**************************************************
2023/12/18
VFP C++ Compiler 2023 RELEASE.
**************************************************
2023/12/12
New Features:
1, /VCLOWERCASEFILENAME=ON|OFF Lowercase File Name
--------------------------------------
VFP C++ Compiler Update 20231212
--------------------------------------
1, /VCLOWERCASEFILENAME=ON|OFF Lowercase File Name
The default is ON, VFP C++ Compiler saves lowercase file name in the the executable file.
If set to OFF, VFP C++ Compiler saves uppercase file name in the the executable file.
In the VFP C++ Compiler old version,
there are some problems about uppercase file name in Spanish.
In the VFP C++ Compiler new version,
if we set /VCLOWERCASEFILENAME=ON (the default setting),
there is no problem about file name in Spanish.
**************************************************
2023/12/11
Bugs Fixed:
1, Preprocessor directives problem.
--------------------------------------
VFP C++ Compiler Update 20231211
--------------------------------------
1, Preprocessor directives problem.
The VFP C++ Compiler old version can only process the preprocessor directives without space, for example,
#INCLUDE vctest.h
#DEFINE XX2 "Y"
it can't process the preprocessor directives with spaces or tabs, for example,
# INCLUDE vctest.h
# DEFINE XX2 "Y"
The VFP C++ Compiler new version can process the preprocessor directives without space
and the preprocessor directives with spaces or tabs, for example,
#INCLUDE vctest.h
#DEFINE XX2 "Y"
# INCLUDE vctest.h
# DEFINE XX2 "Y"
The VFP C++ Compiler new version has fixed the bug.
**************************************************
2023/11/25
Bugs Fixed:
1, File names containing multiple contiguous spaces of the Picture property problem.
2, The RelationalExpr property in class definition problem.
3, #DEFINE preprocessor directive compilation speed optimization.
4, DIMENSION statement syntax error problem.
5, FOR EACH ... ENDFOR statement problem.
--------------------------------------
VFP C++ Compiler Update 20231125
--------------------------------------
1, File names containing multiple contiguous spaces of the Picture property problem.
For example,
Picture = fox abc.bmp
There are 5 spaces in the file name,
the old VFP C++ Compiler will compress the 5 spaces to 1 space,
it will be converted to:
Picture = fox abc.bmp
then vfp will get wrong Picture property.
The VFP C++ Compiler new version has fixed the bug for the following *Picture / *Icon properties:
DisabledPicture
DownPicture
OLEDragPicture
Picture
DragIcon
Icon
MouseIcon
2, The RelationalExpr property in class definition problem.
For example,
Add Object Relation1 As Relation With ;
ParentAlias = "Table_Parent",;
RelationalExpr = "field1+field2",;
ChildAlias = "Table_Child",;
ChildOrder = "MainOrder"
In the old VFP C++ Compiler,
it will display an error: RelationalExpr Expression Error or Unknown.
The VFP C++ Compiler new version has fixed the bug.
3, #DEFINE preprocessor directive compilation speed optimization.
For example, for the code:
#IF XX1
#DEFINE XX2 "Y"
#ELSE
#DEFINE XX2 "N"
#ENDIF
the const name XX2 has been defined 2 (or more) times,
VFP C++ Compiler will take more time to process the const name XX2,
so VFP C++ Compiler will run slow.
I did some changes in the VFP C++ Compiler new version.
If a const name is defined many times, and they are defined the same value, for example,
#DEFINE XX2 "Y"
#DEFINE XX2 "Y"
VFP C++ Compiler will process these #DEFINE preprocessor directives very fast.
If a const name is defined many times, and they are not defined the same value, for example,
#IF XX1
#DEFINE XX2 "Y"
#ELSE
#DEFINE XX2 "N"
#ENDIF
VFP C++ Compiler will process these #DEFINE preprocessor directives slow.
4, DIMENSION statement syntax error problem.
In VFP9, for example, the code:
DIMENSION aFiles(1) = "Default_Item"
will be compiled to:
DIMENSION aFiles(1)
so there is no error for the compiled fxp/app/exe files.
In the VFP C++ Compiler old version, for example, the code:
DIMENSION aFiles(1) = "Default_Item"
will be converted to:
DIMENSION ("aFiles(1)") = "Default_Item"
so there is an error for the compiled fxp/app/exe files.
In the VFP C++ Compiler new version, for example, the code:
DIMENSION aFiles(1) = "Default_Item"
will be converted to:
DIMENSION ("aFiles(1)")
so there is no error for the compiled fxp/app/exe files,
and VFP C++ Compiler will display the compilation error messages:
DIMENSION Syntax Error: DIMENSION aFiles(1) = "Default_Item"
and write the error message to the error log (.err) file.
The VFP C++ Compiler new version has fixed the bug for the following statements:
PUBLIC | PRIVATE | LOCAL | DIMENSION | DECLARE [ARRAY] Syntax Error.
5, FOR EACH ... ENDFOR statement problem.
For example,
FOR n1=1 TO 130
?n1
LOCAL lcComputerName, loWMIService, loItems, loItem
lcComputerName = "."
loWMIService = GETOBJECT("winmgmts:\\" + lcComputerName + "\root\cimv2")
loItems = loWMIService.ExecQuery("Select * from Win32_NetworkAdapter",,48)
FOR EACH loItem IN loItems
?loItem.name
ENDFOR
ENDFOR
_FreeObject() API Library Routine (form the vfp help file DV_FOXHELP9.CHM):
If an object reference is returned from any Visual FoxPro API function,
for example, _Evaluate() or _GetObjectProperty(),
you must use _FreeObject() to release the object when you are no longer using it.
In the old VFP C++ Compiler,
it will create a backup object of the group object,
and then it will call the _Evaluate() function to evaluate the backup object,
but it will not call the _FreeObject() function to free the backup object,
and the maximum number of objects in an API Library is 128,
so it will cause an error:
There is not enough memory to complete this operation (Error 43).
The VFP C++ Compiler new version has fixed the bug.
**************************************************
2023/3/6
New Features:
1, /VCRUNTIMELIBRARYFILETYPE=n File Type of the VC Runtime Library (only support Visual FoxPro Advanced)
--------------------------------------
VFP C++ Compiler Update 20230306
--------------------------------------
1, /VCRUNTIMELIBRARYFILETYPE=n File Type of the VC Runtime Library (only support Visual FoxPro Advanced)
For Visual FoxPro Advanced, we can select the file type of the VC runtime library
of the compiled executable files:
-2 - The VC runtime library file is MSVCR70.DLL
-1 - The VC runtime library file is MSVCR71.DLL
0 - The VC runtime library file is MSVCR100.DLL
1 - The VC runtime library file is MSVCR10064.DLL
2 - The VC runtime library file is MSVCRA64.DLL
If we set /VCRUNTIMELIBRARYFILETYPE=2,
we can save the 32-bit executable files and the 64-bit executable files in the same folder, for example,
MYAPP.EXE && the 32-bit executable file
MYAPP.DLL && the 32-bit dynamic link library file
MSVCR100.DLL && the 32-bit Visual C++ Runtime Library
VFPAR.DLL && the 32-bit VFP Advanced Runtime Library
MYAPP64.EXE && the 64-bit executable file
MYAPP64.DLL && the 64-bit dynamic link library file
MSVCRA64.DLL && the 64-bit Visual C++ Runtime Library
VFPAR64.DLL && the 64-bit VFP Advanced Runtime Library
**************************************************
2023/2/26
Bugs Fixed:
1, DEFINE CLASS ... OF ... statement problem.
--------------------------------------
VFP C++ Compiler Update 20230226
--------------------------------------
1, DEFINE CLASS ... OF ... statement problem.
For example,
DEFINE CLASS custom_vctest2 AS custom_vctest OF mylib.vcx
ENDDEFINE
For the old VFP C++ Compiler,
it will create 2 names custom_vctest2 and custom_vctest:mylib.vcx in the name table index,
and then it will display an error message "Create the global name table index failed".
For the new VFP C++ Compiler,
it will create 2 names custom_vctest2 and custom_vctest in the name table index,
and then it will run fine.
**************************************************
2023/2/12
New Features:
1, Support for all versions of Visual C++ 14.3 (Visual Studio 2022).
--------------------------------------
VFP C++ Compiler Update 20230212
--------------------------------------
Now VFP C++ Compiler can support for all versions of Visual C++ 14.3 (Visual Studio 2022).
For the history of Visual C++ 14.3 (Visual Studio 2022), please refer to:
https://learn.microsoft.com/en-us/visualstudio/releases/2022/release-notes

https://learn.microsoft.com/en-us/visualstudio/releases/2022/release-notes-v17.0
**************************************************
2023/2/1
New Features:
1, /VCADDPROC=ON|OFF Load Additional Procedure Files
/VCADDPROCLIST=... Additional Procedure Files List
--------------------------------------
VFP C++ Compiler Update 20230201
--------------------------------------
For example,
SET PROCEDURE TO ("myaddproc.fxp") ADDITIVE
USE VCTEST.DBF EXCLUSIVE
INDEX ON myfunc(vexp) TAG vexp
So, we must load the procedure file myaddproc.fxp first,
and then we can open the table file vctest.dbf.
In the old VFP C++ Compiler,
it will not load the procedure file myaddproc.fxp,
so it will cause an error: Open Table File Error.
In the new VFP C++ Compiler,
we can set:
/VCADDPROC=ON
/VCADDPROCLIST=myaddproc.fxp
so it will load the procedure file myaddproc.fxp first,
so it can run fine.
**************************************************
2023/1/30
Bugs Fixed:
1, Fixed some bugs for some commands about clear the compiled program buffer automatically.
--------------------------------------
VFP C++ Compiler Update 20230130
--------------------------------------
Usually, the following commands will clear the compiled program buffer automatically:
Activate another application, when Visual FoxPro is running in interactive mode (in the command window)
CLEAR PROGRAM command
DOEVENTS command
MODIFY COMMAND command and MODIFY FILE command, specify the name of the text editor (TEDIT = [/N] editor)
in the configuration file
RUN or ! command, when Visual FoxPro is not running in a VFP API Library routine
SET DEVELOPMENT ON command
CHDIR (or CD) command and SET DEFAULT command, when Visual FoxPro Advanced is not running
in a VFP API Library routine
In the old VFP C++ Compiler, sometimes there are some problems for the following commands:
MODIFY COMMAND command and MODIFY FILE command, specify the name of the text editor (TEDIT = [/N] editor)
in the configuration file
The VFP C++ Compiler new version has fixed the bug.
**************************************************

VFP C++ Compiler 2022 RELEASE.
**************************************************
2022/10/30
New Features:
1, /VCNOTDISPLAY_COMPILEERROR=ON|OFF Does Not Display Compilation Error Messages
--------------------------------------
VFP C++ Compiler Update 20221030
--------------------------------------
1, /VCNOTDISPLAY_COMPILEERROR=ON|OFF Does Not Display Compilation Error Messages
The default is OFF, VFP C++ Compiler displays compilation error messages.
If set to ON, VFP C++ Compiler does not display compilation error messages.
In the old VFP C++ Compiler,
if there are some compilation errors,
VFP C++ Compiler saves compilation error messages to the error log (.err) file.
In the new VFP C++ Compiler,
if there are some compilation errors,
VFP C++ Compiler saves compilation error messages to the error log (.err) file,
and displays compilation error messages.
**************************************************
2022/9/25
Bugs Fixed:
1, Fixed some bugs for COM server programs and the compile options /VCNAMEMULTIPROJ=ON|OFF
Compile Variable Names for Multiple Projects.
--------------------------------------
VFP C++ Compiler Update 20220925
--------------------------------------
In the old VFP C++ Compiler,
for COM server programs,
we can not select the compile options /VCNAMEMULTIPROJ=ON|OFF Compile Variable Names for Multiple Projects.
The VFP C++ Compiler new version has fixed the bug.
**************************************************
2022/9/12
New Features:
1, /VCNEWNAMEMODE=n Create the Name Table Index Mode (only support Visual FoxPro Advanced)
--------------------------------------
VFP C++ Compiler Update 20220912
--------------------------------------
1, /VCNEWNAMEMODE=n Create the Name Table Index Mode (only support Visual FoxPro Advanced)
For Visual FoxPro Advanced, we can select the Create the Name Table Index Mode:
0 - Old Mode to Create the Name Table Index
1 - New Mode to Create the Name Table Index
2 - Auto Mode to Create the Name Table Index
**************************************************
2022/9/10
Bugs Fixed:
1, Fixed some bugs for Access or Assign methods.
--------------------------------------
VFP C++ Compiler Update 20220910
--------------------------------------
In the old VFP C++ Compiler,
sometimes there are some problems for Access or Assign methods.
The VFP C++ Compiler new version has fixed the bug.
**************************************************
2022/8/24
New Features:
1, /VCSTEP_ONERROR=ON|OFF Single Step Compile On Error Code
2, /VCSTEP_ONESCAPE=ON|OFF Single Step Compile On Escape Code
**************************************************
2022/6/16
Bugs Fixed:
1, Fixed some bugs for the compile options /VCENCRYPTPCODE=ON|OFF Encrypt P-Code
and /VCFASTENCRYPTPCODE=ON|OFF Fast Encrypt P-Code.
--------------------------------------
VFP C++ Compiler Update 20220616
--------------------------------------
For example,
PUBLIC m.p_count
m.p_count=1
IF TYPE("_SCREEN.custom_vctest1")="O"
_SCREEN.REMOVEOBJECT("custom_vctest1")
ENDI
_SCREEN.ADDOBJECT("custom_vctest1","custom_vctest")
_SCREEN.custom_vctest1.method1()
RETU
DEFINE CLASS custom_vctest AS CUSTOM
property1=0
FUNCTION method1
IF m.p_count<=5
m.p_count=m.p_count+1
THIS.method1()
ENDIF
THIS.property1=SECOND()
RETU
FUNCTION property1_assign
LPARAMETERS tnvalue
THIS.property1=tnvalue
THIS.method1()
RETU
ENDDEFINE
When vfp runnig the statement "THIS.property1=SECOND()",
it will run the property1_assign() method,
and then it will run into the method1() method again,
and then it will run the statement "THIS.property1=SECOND()" again...
This is a recursive routine.
In the old VFP C++ Compiler,
for some recursion code in property_access or property_assign methods,
there are some bugs for the compile options /VCENCRYPTPCODE=ON|OFF Encrypt P-Code
and /VCFASTENCRYPTPCODE=ON|OFF Fast Encrypt P-Code.
The VFP C++ Compiler new version has fixed the bug.
**************************************************
2022/5/18
New Features:
1, /VCANTIDECOMPILE=ON|OFF Anti-Decompile
**************************************************
2022/4/7
New Features:
1, Automatic use "Single Step Compile Mode" to compile the statements between
ON ESCAPE command and ON ESCAPE.
--------------------------------------
VFP C++ Compiler Update 20220407
--------------------------------------
1, Automatic use "Single Step Compile Mode" to compile the statements between
ON ESCAPE command and ON ESCAPE.
For example,
cancelado = .f.
SET ESCAPE ON
ON ESCAPE cancelado = .t.
numeroDato=1
totalDato=100000
WAIT CLEAR
DO WHILE numeroDato<=100000
IF cancelado
IF messagebox("Do you want to cancel the process?","Cancel.",4+32+256) = 6
EXIT
ELSE
cancelado = .f.
ENDIF
ENDIF
WAIT WINDOW NOWAIT ALLTRIM(STR(numeroDato/1000))+"%. Press ESC to cancel the process."
numeroDato=numeroDato+1
ENDDO
SET ESCAPE off
ON ESCAPE
For the older version,
it will compile the vfp code:
numeroDato=1
totalDato=100000
WAIT CLEAR
DO WHILE numeroDato<=100000
IF cancelado
IF messagebox("Do you want to cancel the process?","Cancel.",4+32+256) = 6
EXIT
ELSE
cancelado = .f.
ENDIF
ENDIF
WAIT WINDOW NOWAIT ALLTRIM(STR(numeroDato/1000))+"%. Press ESC to cancel the process."
numeroDato=numeroDato+1
ENDDO
to one C funciton __VC_TEST_xxx().
It will run all code in the C funciton __VC_TEST_xxx(),
and then check the ESC key,
and then call the ON ESCAPE handling (run the code: cancelado = .t.).
The new VFP C++ Compiler will automatic compile the vfp code between:
ON ESCAPE xxx
...
...
...
ON ESCAPE (or ON ESCAPE *, or ON ESCAPE &xxx)
as "Single Step Compile Mode":
ON ESCAPE cancelado = .t.
__VC_TEST_A(1)
__VC_TEST_A(2)
__VC_TEST_A(3)
DO WHILE __VC_TEST_A(4)
IF __VC_TEST_A(5)
IF __VC_TEST_A(6)
EXIT
ELSE
__VC_TEST_A(7)
ENDIF
ENDIF
__VC_TEST_A(8)
__VC_TEST_A(9)
ENDDO
__VC_TEST_A(10)
ON ESCAPE
then it can run fine.
**************************************************
2021/12/24
VFP C++ Compiler 2021 RELEASE.
**************************************************
2021/12/16
Bugs Fixed:
1, Fixed some bugs for the SYS(17) function.
--------------------------------------
VFP C++ Compiler Update 20211216
--------------------------------------
For the following code:
#IF SYS(17) = "X64"
?"VFP Advanced 64-bit version"
#ELSE
?"VFP Advanced 32-bit version"
#ENDIF
When the old VFP C++ Compiler 32-bit compiled and generated the Win32 executable file,
and then run the Win32 executable file, it will display "VFP Advanced 32-bit version",
it is correct.
When the old VFP C++ Compiler 64-bit compiled and generated the Win64 executable file,
and then run the Win64 executable file, it will display "VFP Advanced 64-bit version".
it is correct.
When the old VFP C++ Compiler 32-bit compiled and generated the Win64 executable file,
and then run the Win64 executable file, it will display "VFP Advanced 32-bit version",
it is incorrect.
When the old VFP C++ Compiler 64-bit compiled and generated the Win32 executable file,
and then run the Win32 executable file, it will display "VFP Advanced 64-bit version".
it is incorrect.
The VFP C++ Compiler new version has fixed the bug.
For the following code:
IF SYS(17) = "X64"
?"VFP Advanced 64-bit version"
ELSE
?"VFP Advanced 32-bit version"
ENDIF
The compiled executable file will call the SYS(17) function at runtime instead of compile time,
so there is no the bug in the VFP C++ Compiler old version.
The the _WIN64 system variable can only be used at runtime, it can not be used at compile time,
so there is no the bug for the the _WIN64 system variable.
**************************************************

/VCMULTITASK_COMPILEDLL=ON|OFF Multi-Task Compile the DLL Source Files
/VCMULTITASKNUMBER_COMPILEDLL=n Multi-Task Number for Compiling the DLL Source Files
--------------------------------------
VFP C++ Compiler Update 20200906
--------------------------------------
1, /VCMULTITASK_COMPILEFORM=ON|OFF Multi-Task Compile the Large Form File
/VCMULTITASKNUMBER_COMPILEFORM=n Multi-Task Number for Compiling the Large Form File
VFP C++ Compiler generates a large form file which contains all code in the VFP project file,
sometimes the size of the large form file is great than 100 MB,
and it takes more than 10 minutes to compile the large form file.
Recommend to set the following compile options for multi-core or multi-thread CPU:
/VCMULTITASK_COMPILEFORM=ON Multi-Task Compile the Large Form File
/VCMULTITASKNUMBER_COMPILEFORM=4 Multi-Task Number for Compiling the Large Form File
then VFP C++ Compiler can compile faster.
If we set:
/VCMULTITASK=ON Multi-Task Compile Mode
VFP C++ Compiler will run multi-task to compile the large form file automatically.
2, /VCMULTITASK_COMPILEDLL=ON|OFF Multi-Task Compile the DLL Source Files
/VCMULTITASKNUMBER_COMPILEDLL=n Multi-Task Number for Compiling the DLL Source Files
VFP C++ Compiler generates many C/C++ files (foxrun*.c),
sometimes the size of the C/C++ files are great than 100 MB,
and it takes more than 10 minutes to compile the C/C++ files.
Recommend to set the following compile options for multi-core or multi-thread CPU:
/VCMULTITASK_COMPILEDLL=ON Multi-Task Compile the DLL Source Files
/VCMULTITASKNUMBER_COMPILEDLL=4 Multi-Task Number for Compiling the DLL Source Files
then VFP C++ Compiler can compile faster.
If we set:
/VCMULTITASK=ON Multi-Task Compile Mode
VFP C++ Compiler will run multi-task to compile the DLL source files automatically.

Bugs Fixed:
1, Fixed some bugs for COM server programs.
2, Fixed some bugs for the compile option /APPDEBUG=ON|OFF Application Debug Mode.
--------------------------------------
VFP C++ Compiler Update 20200816
--------------------------------------
1, Fixed some bugs for COM server programs.
If the COM server program is small, there is no problem in the VFP C++ Compiler old version.
If the COM server program is bigger, there are some bugs in the VFP C++ Compiler old version.
The VFP C++ Compiler new version has fixed the bug.
2, Fixed some bugs for the compile option /APPDEBUG=ON|OFF Application Debug Mode.
The VFP C++ Compiler old version only creates an 'after' application debug log:
<VFP statement>
after_log
Usually, for almost VFP statements,
the VFP C++ Compiler new version creates 2 application debug logs:
before_log
<VFP statement>
after_log
VFP C++ Compiler does NOT create an application debug log for the following statements:
TEXT ... ENDTEXT
properties in DEFINE CLASS ... ENDDEFINE (between endfunc/endproc and Function/proc)
PROCEDURE
FUNCTION
PROTECTED
HIDDEN
PARAMETERS
LPARAMETERS
ENDDEFINE
Preprocessor Directives (starts with #)
VFP C++ Compiler only creates an 'after' application debug log for the following statements:
ELSE
CASE
OTHERWISE
CATCH
FINALLY
<VFP statement>
after_log
VFP C++ Compiler only creates a 'before' application debug log for the following statements:
DO CASE
LOOP
EXIT
THROW
RETURN
ENDxxx (except ENDDEFINE)
before_log
<VFP statement>

**************************************************
2020/6/20
New Features:
1, Support for multiple-instances of VFP C++ Compiler.
--------------------------------------
VFP C++ Compiler Update 20200620
--------------------------------------
In the old VFP C++ Compiler,
we can only run single-instance of VFP C++ Compiler.
If we want to compile many projects, we can create a batch file compileall.bat, for example,
START /W "C:\Program Files\Baiyujia VFP C++ Compiler\VC.EXE" "D:\PROG1\PROG1.VCF" /SILENT=ON
START /W "C:\Program Files\Baiyujia VFP C++ Compiler\VC.EXE" "D:\PROG2\PROG2.VCF" /SILENT=ON
START /W "C:\Program Files\Baiyujia VFP C++ Compiler\VC.EXE" "D:\PROG3\PROG3.VCF" /SILENT=ON
when we running the batch file compileall.bat,
it will compile the 1st project, and the 2nd project, and the 3rd project.
In the new VFP C++ Compiler,
we can run multiple-instances of VFP C++ Compiler.
If we want to compile many projects, we can create a batch file compileall.bat, for example,
START "C:\Program Files\Baiyujia VFP C++ Compiler\VC.EXE" "D:\PROG1\PROG1.VCF" /SILENT=ON
START "C:\Program Files\Baiyujia VFP C++ Compiler\VC.EXE" "D:\PROG2\PROG2.VCF" /SILENT=ON
START "C:\Program Files\Baiyujia VFP C++ Compiler\VC.EXE" "D:\PROG3\PROG3.VCF" /SILENT=ON
when we running the batch file compileall.bat,
it will run 3 instances of VFP C++ Compiler,
they will compile the 3 projects at the same time.

/VCADDFLLLIST=... Additional VFP API Library Files List
--------------------------------------
VFP C++ Compiler Update 20200330
--------------------------------------
For example,
SET LIBRARY TO ("FOXTOOLS.FLL") ADDITIVE
USE VCTEST.DBF EXCLUSIVE
INDEX ON WORDS(vexp) TAG WORDS
So, we must load the VFP API library file foxtools.fll first,
and then we can open the table file vctest.dbf.
In the old VFP C++ Compiler,
it will not load the VFP API library file foxtools.fll,
so it will cause an error: Open Table File Error.
In the new VFP C++ Compiler,
we can set:
/VCADDFLL=ON
/VCADDFLLLIST=FOXTOOLS.FLL
so it will load the VFP API library file foxtools.fll first,
so it can run fine.

--------------------------------------
VFP C++ Compiler Update 20190525
--------------------------------------
Usually, we can create the version information file FOXRUN\RSRCDLL\RSRCDLL.RC in the project folder,
then when VFP C++ Compiler build the dynamic link library file,
the version information file will be embedded into the dynamic link library file automatically.
For example, we can create the version information file such as:
/////////////////////////////////////////////////////////////////////////////
//
// Version
//
1 VERSIONINFO
FILEVERSION 10,0,0,0
PRODUCTVERSION 10,0,0,0
FILEFLAGSMASK 0x3fL
#ifdef _DEBUG

END
END
BLOCK "VarFileInfo"
BEGIN

END
END
If there is the version information in the project file,
VFP C++ Compiler will update the following version number in the version information file automatically:
FILEVERSION 10,0,0,0
PRODUCTVERSION 10,0,0,0
VALUE "FileVersion", "10.0.0.0\0"
VALUE "ProductVersion", "10.0.0.0\0"
then the version number in the executable file is the same version number in the dynamic link library file.

1, Project includes database files problem.
For example,
the project includes some database files:
testdata1.dbc
testdata2.dbc
testdata3.dbc
...
these database files (*.dbc, *.dct and *.dcx) will be compiled into the executable file.
For the old VFP C++ Compiler,
these database files (*.dbc, *.dct and *.dcx) will be opened in the system data session automatically
when opening the table (*.dbf) files,
so these database files (*.dbc, *.dct and *.dcx) will NOT be compiled into the executable file,
so the compiled executable file is a corrupted executable file and it can't run.
For the new VFP C++ Compiler,
it will run the command "CLOSE DATABASE ALL" first,
so these database files (*.dbc, *.dct and *.dcx) will be compiled into the executable file,
so it can run fine.

Usually, we can create a user-defined manifest file <PROJECT-NAME>.EXE.manifest,
then when VFP build the executable file,
the user-defined manifest file will be embedded into the executable file automatically.
For example, for the Win32 executable files compiled with Visual FoxPro 32-bit,
we can create a user-definded manifest file such as:

VFP C++ Compiler only convert the VFP base class object's properties into procedure init,
so convert faster.
If we set:
/VCFASTFRXINIT=ON Fast Convert Report's Expressions into Procedure Init
VFP C++ Compiler only convert the TextBox control's expressions into procedure init,
it does not convert the Label control's expressions into procedure init,
so convert faster.

VFP C++ Compiler Update 20141120
--------------------------------------
1, /VCMULTITASK=ON|OFF Multi-Task Compile Mode
/VCMULTITASKNUMBER=n Multi-Task Number for Compiling Files
Usually we can set the multi-task number to the maximum number of threads for the CPU supported,
for example, for a 2 cores 4 threads CPU, we can set it to 4:
/VCMULTITASK=ON Multi-Task Compile Mode
/VCMULTITASKNUMBER=4 Multi-Task Number for Compiling Files
Usually, if we set the multi-task number to 4 for a 4 threads CPU,
the compiled time is about 60% of the compiled time of the single-task compile.
If we set the multi-task number to 8 for a 8 threads CPU,
the compiled time is about 40% of the compiled time of the single-task compile.
Recommend to set the following compile options for multi-core or multi-thread CPU:
/VCINCREMENTAL=ON Incremental Compile Mode
/VCSAVEINCREMENTAL=ON Save Incremental Compile Files
/VCMULTITASK=ON Multi-Task Compile Mode
/VCMULTITASKNUMBER=4 Multi-Task Number for Compiling Files

/VCPACK=ON|OFF Pack Executable File
/DEBUG=ON|OFF Debug Mode
/SILENT=ON|OFF Silent Mode
/VCINCREMENTAL=ON|OFF Incremental Compile Mode
/VCSAVEINCREMENTAL=ON|OFF Save Incremental Compile Files
or the incremental compile files have been deleted,
or the main program file has been modified.
Usually, first, we can set:
/VCINCREMENTAL=ON Incremental Compile Mode
/VCSAVEINCREMENTAL=ON Save Incremental Compile Files
and compile the VFP project.
After this, if we set:
/VCINCREMENTAL=ON Incremental Compile Mode
/VCSAVEINCREMENTAL=ON Save Incremental Compile Files
VFP C++ Compiler only compile the modified files in the VFP project file,
that is VFP C++ Compiler can compile faster.
If we need re-compile the VFP project, we can set:
/VCINCREMENTAL=OFF does not compile with Incremental Compile Mode
/VCSAVEINCREMENTAL=ON Save Incremental Compile Files
VFP C++ Compiler will re-compile all files in the VFP project file.

Bugs Fixed:
1, /VCTOLARGEPROC=ON|OFF Compile to Large Procedure Files Format (only used for VFP 9.0)
2, SET TALK ON in private data session problem.
--------------------------------------
VFP C++ Compiler Update 20140918
--------------------------------------
1, /VCTOLARGEPROC=ON|OFF Compile to Large Procedure Files Format (only used for VFP 9.0)
For VFP Advanced, it ALWAYS compile to large procedure files format and it has fixed
the large program files BUG, so there is no the compile option for VFP Advanced.
For VFP 6.0, 7.0 and 8.0, it does not support large procedure files format, so there is
no the compile option for VFP 6.0, 7.0 and 8.0.
For VFP 9.0,
If we set:
/VCTOLARGEPROC=ON Compile to Large Procedure Files Format
VFP C++ Compiler will compile to large procedure files format and automatically fix
the large program files BUG.
IMPORTANT NOTE:
For the old VFP C++ Compiler,
because the VFP project's version (9.0) is not the same as VFP C++ Compiler's version (10.0),
VFP C++ Compiler will create a temporary program file <PROJECT-NAME>$VCC$.PRG:
ON ERROR *
SET TALK OFF
SET RESOURCE OFF
SET NOTIFY OFF
COMPILE ("VCTEST.PRG")
CLEAR ALL
CLOSE ALL
QUIT
and then run VFP9.EXE <PROJECT-NAME>$VCC$.PRG to compile files,
but there is a problem for this method,
1, the VFP C++ Compiler window lost focus,
2, the VFP 9 windows got focus (although it has the SW_HIDE property),
3, the VFP C++ Compiler window got focus,
so the VFP C++ Compiler window is flashing.
For the new VFP C++ Compiler,
in fact, for ALMOST all files in the project,
1, VFP C++ Compiler compiled to large procedure files format (the VFP Advanced version format),
2, VFP C++ Compiler converted the VFP Advanced version format to the VFP 9.0 version format,
VFP C++ Compiler need not create a temporary program file <PROJECT-NAME>$VCC$.PRG and run it,
so there is no the flash problem, and compile faster.
About the large procedure files format, please refer to:
baiyujia website: www.baiyujia.com/vfpdocuments/f_vhfox.asp
vfp9 procedure size >64K format
Before vfp9, procedure size <64K, use one WORD can save the size of procedure:
00-01 DW size of procedure
In vfp9, procedure size >64K possible, use one WORD and one DWORD to save the size of procedure:
00-01 DW 0
02-05 DD size of procedure
2, /VCNOTDISPLAY_LARGEPROC=ON|OFF Does Not Display Large Program Files in the Project
(only used for VFP 9.0)
About the large program files BUG, please refer to:
baiyujia website: www.baiyujia.com/vfpdocuments/f_vfp9fix2.asp
Usually, if we set:
/VCTOLARGEPROC=ON Compile to Large Procedure Files Format
then all files in the project will be compiled to large procedure files format,
so we needn't to display large program files in the project.
So recommend to set:
/VCTOLARGEPROC=ON Compile to Large Procedure Files Format
/VCNOTDISPLAY_LARGEPROC=ON Does Not Display Large Program Files in the Project
3, SET TALK ON in private data session problem.
If a form or a report use private data session,
some settings are set to the default values,
for example, SET TALK is set to ON.
Usually, we need change some settings, for example,
SET STEP OFF
SET ECHO OFF
SET DEBUG OFF
SET ESCAPE OFF
SET TALK OFF
SET SAFETY OFF
...
For the old VFP C++ Compiler,
it will insert the statement "SET TALK OFF" into the PROCEDUREs Form.Load() and Form.Init(),
but it will not insert the statement "SET TALK OFF" into the PROCEDUREs
DataEnvironment.BeforeOpenTables() and DataEnvironment.Init().
For the new VFP C++ Compiler,
it will insert the statement "SET TALK OFF" into the PROCEDUREs Form.Load(), Form.Init(),
FormSet.Load(), FormSet.Init(),
ToolBar.Init(), ToolBar.sub-objects.Init(),
DataEnvironment.allmethods(), DataEnvironment.sub-objects.allmethods().
Sometimes, VFP C++ Compiler does not know the form use private data session or not.
For example,
in the class library, we can set:
DataSession = 1 && default data session
but in the form (it is subclassed from the class library), we can set:
DataSession = 2 && private data session
then the form (and the class library) use private data session.
When VFP C++ Compiler compile the class library,
it does not know the class library use private data session or not.
So, for the new VFP C++ Compiler,
it ALWAYS insert the statement "SET TALK OFF" into some PROCEDUREs.

--------------------------------------
1, /VCNAMEEXCLUDEVCD2=ON|OFF Does Not Compile Variable Names in String Delimiters
If we set:
/VCNAMEEXCLUDEVCD2=ON Does Not Compile Variable Names in String Delimiters
VFP C++ Compiler does not compile variable names in string delimiters.
For example,
x1 = 123
?"The value of x1 is "+STR(x1,10)
VFP C++ Compiler does not compile the variable name x1.
2, /VCNAMEEXCLUDEVCD3=ON|OFF Does Not Compile Field Names or Property Names
If we set:
/VCNAMEEXCLUDEVCD3=ON Does Not Compile Field Names or Property Names
VFP C++ Compiler does not compile field names or property names.
For example,
fld1 = 123
?STR(t1.fld1,10)
VFP C++ Compiler does not compile the variable name (or field name) fld1.
3, /VCNAMEEXCLUDEVCW=ON|OFF Does Not Compile Variable Names Specified

If we want does not compile other variable names,
we can set:
/VCNAMEEXCLUDEVCW=ON Does Not Compile Variable Names Specified in the User Reserved Words File
and add the variable names to the user reserved words file (<PROJECT-NAME>.VCW).
For example,
cancelar
or:
cancelar Caption = "Cancelar"
VFP C++ Compiler only get the first word in per line.
4, /VCNAMEONLYTEXTMERGEDELI=ON|OFF For Text Merge Statements, Only Compile Variable Names
in the Text Merge Delimiters
If we set:
/VCNAMEONLYTEXTMERGEDELI=OFF For Text Merge Statements, Compile All Variable Names in the Statements
For example,
x1 = 123
text
The value of x1 is << x1 >>
endtext
will be compiled to:
_vc_aa = 123
text
The value of _vc_aa is << _vc_aa >>
endtext
If we set:
/VCNAMEONLYTEXTMERGEDELI=ON For Text Merge Statements, Only Compile Variable Names

--------------------------------------
VFP C++ Compiler Update 20130501
--------------------------------------
1, Compile and generate a large (greater than 100MB, but less than 250MB) executable file problem.
That is,
the old VFP C++ Compiler can only compile and generate an executable file less than 100MB,
the new VFP C++ Compiler can compile and generate an executable file less than 250MB.
For the dynamic link library file, it can greater than 250MB.
But if the dynamic link library file greater than 250MB, VFP C++ Compiler will not compress it,
because the UPX program can't compress a large executable file (or dynamic link library file)
greater than 250MB.

THISFORM.OLecontrol1.COMmPort=99
IF lOk
WAIT WINDOW 'port open'
thisform.olecontrol1.Enabled=.t.
ELSE

ENDIF
to one C funciton __VC_TEST_xxx().
It will run all code in the C funciton __VC_TEST_xxx(),
and then generates an error,
and then call the ON ERROR handling (run the code: lok = .f.).
The new VFP C++ Compiler will automatic compile the vfp code between:
ON ERROR xxx

1, /VCSTEP=ON|OFF Single Step Compile Mode
--------------------------------------
VFP C++ Compiler Update 20111108
--------------------------------------
1, /VCSTEP=ON|OFF Single-step Compile Mode
The default is OFF, VFP C++ Compiler compiled many VFP statements to one C function.
If set to ON, VFP C++ Compiler compiled only one VFP statement to one C function.
To resolved the ON ERROR, RETURN TO, RETRY statements problem,
Method 1 (the simple method):
we can set:
/VCSTEP=ON Single-step Compile Program
then VFP C++ Compiler will compile the ON ERROR, RETURN TO, RETRY statements same as VFP.
The /VCSTEP=ON|OFF option is used for all files in the project.
This method is simple, we needn't to edit our code,
but the Structured Programming Commands such as:
DO CASE ... ENDCASE
DO WHILE ... ENDDO
FOR EACH ... ENDFOR
FOR ... ENDFOR
IF ... ENDIF
SCAN ... ENDSCAN
TRY ... ENDTRY
will leave in the exe file (VFP code), not in the dll file (C code),
so the code security will be reduced.
Recommend to set:
/VCSTEP=ON Single-step Compile Program
for our old project,
because we needn't to edit our code and the compiled code will run fine.
Please refer to:
vctest\vctest_on_error_vcstep\vctest.vcf, vctest.prg
vctest\vctest_return_to_vcstep\vctest.vcf, vctest.prg
vctest\vctest_retry_vcstep\vctest.vcf, vctest.prg
Method 2 (the recommend method):
Or we can use =[FOXSTEP ON|OFF] statement to set Single-step Compile for some files
(or some code), other files will not be Single-step Compiled.
That is we can set Single-step Compile for some code (relate to the ON ERROR, RETURN TO,
RETRY statements), the code security will be reduced.
Other code will not be Single-step Compiled, so the other code is more secure.
Please refer to:
vctest\vctest_on_error_foxstep\vctest.prg
vctest\vctest_return_to_foxstep\vctest.prg
vctest\vctest_retry_foxstep\vctest.prg
Method 3 (the old method):

then VFP C++ Compiler does not Clean Data for Show Position.
Usually, we can set:

/VCFRX_AUTORELEASEVARIABLES=ON|OFF Automatic Release Variables Defined
in Report's Procedure Init
If we set (the default setting):
/VCFRX_AUTORELEASEVARIABLES=OFF does not Automatic Release Variables Defined
in Report's Procedure Init, then VFP C++ Compiler does not Automatic Release
Variables Defined in Report's Procedure Init.
If there is no more than one report at the same time, that is only one report
at any time, then we can set:
/VCFRX_AUTORELEASEVARIABLES=ON Automatic Release Variables Defined
in Report's Procedure Init, then VFP C++ Compiler will Automatic Release Variables
Defined in Report's Procedure Init.
For example,

1, About Encrypt and Compress Executable File
If we set:
/VCENCRYPT=ON Encrypt Executable File
/VCPACKEXE=ON Compress Executable File
then the Executable File can be compressed, the compression ratio is about 80%.
If we set:
/VCENCRYPT=OFF does not Encrypt Executable File
/VCPACKEXE=ON Compress Executable File
then the Executable File can be compressed very small, the compression ratio is about 20%.
If we set:
/VCENCRYPT=OFF does not Encrypt Executable File
/VCPACKEXE=OFF does not Compress Executable File
then the Executable File can't be compressed,
but you can use other third-party VFP encryption products such as DeFox and FoxShell to
encrypt/compress the Executable File.
2, TRY ... ENDTRY statement problem.
An example from DV_FOXHELP9.CHM:
CLEAR
ON ERROR DO errorHandler && Create a functional error handler to test.
oMyObject=CREATEOBJECT("myClass")
oMyObject.myMethod1()
* oMyObject.myMethod2() && Remove comment character to test this line.
DEFINE CLASS myClass AS Custom
PROCEDURE myMethod1
? "myMethod1"
TRY
? "Calling myMethod2 in TRY block for myMethod1."
THIS.myMethod2()
CATCH TO omyError
? "Entered CATCH block for myMethod1. Caught: ", ;
omyError.ErrorNo, " ", omyError.Message
ENDTRY
ENDPROC
PROCEDURE myMethod2
?
? "myMethod2"
? "Generating an error in myMethod2."
x=y && Variable y does not exist. CATCH handles this error.
? "This line displays if CATCH does not handle the prece* error."
ENDPROC
ENDDEFINE
If we call myMethod2() in a TRY ... ENDTRY block,
? "This line displays if CATCH does not handle the prece* error."
will not be run.
If we call myMethod2() not in a TRY ... ENDTRY block,
? "This line displays if CATCH does not handle the prece* error."
will be run.
I have found a useful function SYS(2410) - Error Handler can resolved this problem.
when causes an error,
if SYS(2410)='1' then call _Error(), the next statements will not be run.
else
the next statements in the C function will be run continue,
at the end, call the _Error(), then jump to the error process program.
Now VFP C++ Compiler can run TRY ... ENDTRY code same as VFP.

VFP C++ Compiler Update 20110801
--------------------------------------
1, Form and Report Compile Options.
For more details, please refer to others\readme*.txt.
IMPORTANT:
Some program use a TextBox object to call a UDF function and set Print When is Flase,
so the UDF function can be called normal, but not print anything in the report.
In this case, we can't Delete Data When Print When is Flase, so we MUST set:
/VCFRX_DELETEDATA_WHEN_PRINTWHENISFALSE=OFF does not Delete Data When Print When
is Flase (Supexpr==".F.")
The old VFP C++ Compiler will automatic Delete Data When Print When is Flase.
So please update to the new VFP C++ Compiler 20110801.
2. Please Download VFP C++ Compiler Runtime Library from:
http://www.baiyujia.com/f_downloadproc_vclib.asp
the password is www.baiyujia.com.
Compress options in make_packexe.bat and make_packdll.bat have changed to:
upx --best --compress-icons=0 %1
If we set:
/VCENCRYPT=OFF does not Encrypt Executable File
then the Executable File can be compressed very small,
it's about 15% of the original file size.
3. If you use Mycheck SDK and selected C/C++ compiler file is foxrun8\make.bat or foxrun9\make.bat,
for some reasons about SEH, the dll code can't run correctly on Windows XP.
The new VFP C++ Compiler 20110801 has fixed this BUG.
If we select Visual C++ 8.0/9.0 to compile foxrun*.c,
then the foxrun.dll include the IMAGE_DIRECTORY_ENTRY_LOAD_CONFIG data,
the IMAGE_DIRECTORY_ENTRY_LOAD_CONFIG save some reserved SEH data,
and it is only used on Windows NT, Windows 2000 and Windows XP.
The new VFP C++ Compiler 20110801 will clear the IMAGE_DIRECTORY_ENTRY_LOAD_CONFIG data,
then the program can run correctly on Windows XP (and Windows vista and Windows 7 and after).

New Features:
1, EXTENDED CODE is not available when set =[FOXRUN OFF].
--------------------------------------
VFP C++ Compiler Update 20110725
--------------------------------------
1, EXTENDED CODE is not available when set =[FOXRUN OFF].
For example,
in the vctest.prg:
...
=[foxrun off]
...
=[include mycheck_isdebuggerpresent.c]
...
=[foxrun on]
...
The statement:
=[include mycheck_isdebuggerpresent.c]
it is only a normal VFP statement, and it do nothing.
The new version VFP C++ Compiler will write a warning message to the vctest.err:
EXTENDED CODE is not available when set =[FOXRUN OFF].
=[include mycheck_isdebuggerpresent.c]
**************************************************
2011/6/26
New Features:
1, /APPERROR=ON|OFF Application Error Log File
--------------------------------------
VFP C++ Compiler Update 20110626
--------------------------------------
1, VFP C++ Compiler version 20110401-20110625 has a BUG:
IF x1>0 ; && xxx
and x2>0 && xxx
...
the old VFP C++ Compiler can't process these statements correctly.
Please update to the new version VFP C++ Compiler 20110626.
2, New Functions: /APPERROR=ON|OFF Application Error Log File
Usually, the code:
?x1
?x2
?x3
VFP C++ Compiler only return the last error:
Variable "x3" is not found
If we set:
/APPERROR=ON Application Error Log File
and then compile the project,
and then run the application,
it will generate an Error Log File include all errors, like:
06/27/11 08:02:50 AM VCTEST: (170) ?X1
06/27/11 08:02:50 AM VCTEST: (170) ?X2
06/27/11 08:02:50 AM VCTEST: (170) ?X3
now we can know it causes 3 errors.
the function is only used for test/debug,
and please set:
/VCOPT=OFF does not Optimize Code
/VCOPT2=OFF does not Optimize Code Level II
because if we set:
/VCOPT=ON Optimize Code
/VCOPT2=ON Optimize Code Level II
the error message in the Error Log File is p-code data,
it is hard to understand.
**************************************************

--------------------------------------
VFP C++ Compiler Update 20110501
--------------------------------------
1, /VCOPT2=ON|OFF Optimize Code Level II.
If we set /VCOPT=ON,
VFP C++ Compiler will Optimize the _Execute() function.
If we set /VCOPT2=ON,
VFP C++ Compiler will Optimize the _Evaluate() function,
then the generated code is smaller and run faster.
2, Support for Windows 7 (x86/x64).
The new version only fix some directories access problem such as:
C:\Windows\System32 and C:\Windows\SysWOW64,
C:\Program Files and C:\Program Files (x86),
then VFP C++ Compiler can normal run on Windows 7 x64 system.
VFP C++ Compiler is a 32-bit program.

Please don't select "Encrypt Executable File",
then VFP C++ Compiler will generate a standard VFP executable file,
then we can use DeFox or FoxShell to encrypt it.
