The information in this article applies to:
- Microsoft Visual SourceSafe for Windows, versions 4.0a, 5.0
- Microsoft Visual FoxPro for Windows, version 5.0
-------------------------------------------------------------------------------
SYMPTOMS
========
When you modify files in a Visual FoxPro project under Source Code Control, it
takes 4 to 5 times longer than if the project is not under Source Code Control.
CAUSE
=====
Instead of updating individual files when individual objects are being modified,
the entire project is updated by default in Source Code Control.
STATUS
======
Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article. This bug has been corrected in Microsoft Visual
FoxPro version 5.0a for Windows.

Steps to Reproduce Problem
--------------------------
1. Run Visual FoxPro v5.0 and create a Visual FoxPro program file, MakMor.prg,
with the following code:
**** Create sample programs ****
FOR i= 1 TO 200
lcname1="main" + maknum(i) + ".prg"
COPY FILE main000.prg TO &lcname1
ENDFOR
**** Create sample forms ****
FOR i= 1 TO 200
lcname1="main" + maknum(i) + ".scx"
lcname2="main" + maknum(i) + ".sct"
COPY FILE main000.scx TO &lcname1
COPY FILE main000.sct TO &lcname2
ENDFOR
PROCEDURE maknum
PARAMETERS tnWhich
RETURN PADL(ALLTRIM(STR(m.tnWhich)),3,"0")
2. Save the program file created in the previous step into a directory by
itself, for example "..\BigProj\". This program will create 200 program files
and forms that will be used to reproduce the behavior.
3. Create a Visual FoxPro program file, MAIN000.prg, with the following code:
&&***Top of MAIN000.PRG****
RETURN
DO MYINIT
DO MYSAVE
DO FORM main
READ EVENTS
PROCEDURE myinit
LOCAL x00,x01,x02,x03,x04,x05,x06,x07,x08,x09
LOCAL x10,x11,x12,x13,x14,x15,x16,x17,x18,x19
STORE 9 TO x00,x01,x02,x03,x04,x05,x06,x07,x08,x09
STORE 9 TO x10,x11,x12,x13,x14,x15,x16,x17,x18,x19
RETURN
PROCEDURE mysave
LOCAL x00,x01,x02,x03,x04,x05,x06,x07,x08,x09
LOCAL x10,x11,x12,x13,x14,x15,x16,x17,x18,x19
LOCAL x20,x21,x22,x23,x24,x25,x26,x27,x28,x29
STORE 9 TO x00,x01,x02,x03,x04,x05,x06,x07,x08,x09
STORE 9 TO x10,x11,x12,x13,x14,x15,x16,x17,x18,x19
STORE 9 TO x20,x21,x22,x23,x24,x25,x26,x27,x28,x29
RETURN
&&***End of MAIN000.PRG****
Save the program into the same directory (..\BigProj) as the program file
created in step 1. This is a sample program whose contents will be copied
into all the sample program files created by MakMor.prg.
4. Create a Visual FoxPro form, MAIN000.SCX, and place a control on the form.
Save the form to the same directory (..\BigProj) as the previous step. The
contents of this form will be copied to all the sample forms created by
MakMor.prg.
5. Create another Visual FoxPro program, MNDAT.PRG, with the following code:
IF !file("main.prg")
FHAND=fcreate("main.prg")
FCLOSE(fhand)
ENDIF
fhand = FOPEN("main.prg",11)
?"fhand = ",fhand
IF FHAND >= 0
FOR i=1 TO 200
fnum=PADL(ALLTRIM(STR(i)),3,"0")
FPUTS(fhand, "Do Main"+(fnum))
** Uncomment the following if forms added to the project **
fputs(fhand, "Do Form Main"+(fnum))
ENDFOR
ENDIF
FCLOSE(fhand)
Save the program to the same directory (..\BigProj) as the previous step. This
program creates MAIN.PRG that contains references to all the forms and
programs created by MakMor.prg.
6. From Visual FoxPro issue the following commands:
SET DEFAULT TO <..\BigProj> ** Set default to where all files saved
DO MakMor.prg **Make sample programs and files
DO MNDAT.prg **Create Main.prg with references to files
7. Create a Project, BigProj.PJX, in the directory (..\BigProj) where all the
files have been saved so far.
8. Add MAIN.PRG to the project and re-build the project to add all the files
referenced by MAIN.PRG.
9. Modify any of the files (Programs or Forms) from within the Project Manager
and note that the modify window opens up instantly.
10. Close all files and add the project to source control.
11. Repeat step 9 and note that the modify window takes much longer to come up.
NOTE: In Visual FoxPro v5.0a step 11 will be almost as fast as step 9.
