[BUG/PRB.] VFP 9.0 FIX - ALL COMMANDS RESET THE OBJECT.NAME PROPERTY
January 2024
------------------------------------------------------------------------------
CCB
1. BUG:
In vfp9 (and vfp6, vfp7, vfp8), the MODIFY FORM command will reset the Form.Name property to the name in the Name Table Index (NTI)
if the name already exists in the Name Table Index (NTI),
sometimes the Form.Name property value will be converted to uppercase.
There is a test program:
*PROC testmodifyformcommand
form_lowername="aaa" && the variable name is the same as the Form.Name property value ("form_lowername").
MODIFY FORM testmodifyformcommand.scx && the Form.Name property value will be converted to uppercase ("FORM_LOWERNAME") in vfp9!
RETURN
* END OF PROC TESTMODIFYFORMCOMMAND.
2. CAUSE:
There are some BUGs in the following code.
3. RESOLUTION:
We can write some code to fix the BUG.

;
; In vfp9, the MODIFY FORM command will reset the Form.Name property to the name in the Name Table Index (NTI)
; if the name already exists in the Name Table Index (NTI),
; sometimes the Form.Name property value will be converted to uppercase.
; In VFP Advanced, the MODIFY FORM command will not reset the Form.Name property.

The bug has been fixed in VFP Advanced.
IMPORTANT NOTE:
Some commands will reset the Object.Name property to the name in the Name Table Index (NTI)
if the name already exists in the Name Table Index (NTI),
sometimes the Object.Name property value will be converted to uppercase, lowercase or mixedcase.
We can use the Form.Name property to locate a form, for example,
PRIVATE m.q_form_main
m.q_form_main=""
PRIVATE m.q_forms_nn
m.q_forms_nn=1
DO WHILE TYPE("_SCREEN.FORMS(m.q_forms_nn)")="O"
IF UPPE(ALLTRIM(_SCREEN.FORMS(m.q_forms_nn).NAME))==UPPE(ALLTRIM("form_main"))
m.q_form_main=_SCREEN.FORMS(m.q_forms_nn)
EXIT
ENDI
m.q_forms_nn=m.q_forms_nn+1
ENDDO
