BUG: Project Manager Limitation in Standard Mode FoxPro

• Microsoft FoxPro for MS-DOS, version 2.5, 2.5a, 2.5b, 2.6

SYMPTOMS

In the Standard (16-bit) version of FoxPro for MS-DOS, versions 2.5x and later, if a project has a large number of files (any number above 75, depending on what types of files are in the project and the size of each file), and another file is added to the project, that file will be removed after the project is built. This behavior will occur after the project has been saved and reopened.

NOTE: This problem does NOT occur in the Extended (32-bit) version.

CAUSE

This problem might be caused by the combined compiled size of the files in the project.

RESOLUTION

At this time, there is no resolution or workaround for this problem.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

Steps to Reproduce Behavior

1. Type the following code into a program file:

         FOR i=1 to 108
            SET  PRINTER TO "prg" + ALLTRIM(STR(i)) + ".prg"
            WAIT WINDOW "Writing Program: "+SET('PRINTER',1) NOWAIT
            SET PRINTER ON
            ?"WAIT WINDOW 'This is a program' TIME 4"
            SET PRINTER OFF
            SET PRINTER TO
         ENDFOR
         SET TALK OFF
         SET PRINTER TO test2.prg
         SET PRINTER ON
         ? "BUILD PROJECT test FROM  ;"
         FOR outer = 1 to 108 STEP 9
            IF outer = 100
               ? "prg" + ALLTRIM(STR(outer))+ ","
               ?? "prg"+ALLTRIM(STR(outer +1)) +","
               ?? "prg"+ALLTRIM(STR(outer +2)) +","
               ?? "prg"+ALLTRIM(STR(outer +3)) +","
               ?? "prg"+ALLTRIM(STR(outer +4)) +","
               ?? "prg"+ALLTRIM(STR(outer +5)) +","
               ?? "prg"+ALLTRIM(STR(outer +6)) +","
               ?? "prg"+ALLTRIM(STR(outer +7)) +","
               ?? "prg"+ALLTRIM(STR(outer +8))
            ELSE
               ? "prg" +ALLTRIM(STR(outer))+ ","
               ?? "prg"+ALLTRIM(STR(outer +1)) +","
               ?? "prg"+ALLTRIM(STR(outer +2)) +","
               ?? "prg"+ALLTRIM(STR(outer +3)) +","
               ?? "prg"+ALLTRIM(STR(outer +4)) +","
               ?? "prg"+ALLTRIM(STR(outer +5)) +","
               ?? "prg"+ALLTRIM(STR(outer +6)) +","
               ?? "prg"+ALLTRIM(STR(outer +7)) +","
               ?? "prg"+ALLTRIM(STR(outer +8)) +",;"
            ENDIF
         ENDFOR
         SET PRINTER OFF
         SET PRINTER TO
         DO test2.prg
         SET SYSMENU ON
         MODIFY PROJECT test
   
   

2. Press CTRL+W to save the project.

3. In the Command window, type:
