[BUG/PRB.] VFP 9.0 FIX - CLEAN THE TEMPORARY PATH IN THE COMPILED EXECUTABLE FILES
January 2024
--------------------------------------------------------------------------------------------
CCB
1. BUG:
In vfp9 (and vfp6, vfp7, vfp8), there is the temporary path in the compiled executable files.
2. CAUSE:
In vfp9 (and vfp6, vfp7, vfp8), for the following BUILD EXE command:
CD c:\myapp
BUILD PROJECT vctest.pjx FROM vctest.prg
BUILD EXE vctest.exe FROM vctest.pjx
vfp will compile c:\myapp\vctest.prg to C:\Users\UserName\AppData\Local\Temp\vctest.fxp (now the main folder is the temporary path),
and then save the content of C:\Users\UserName\AppData\Local\Temp\vctest.fxp to the field Object in the project file vctest.pjx,
and then read data from the field Object in the project file vctest.pjx,
and then write data to the executable file vctest.exe,
so there is the temporary path in the compiled executable file (and the field Object in the project file).
There are some BUGs in the following code.
3. RESOLUTION:
We can write some code to fix the BUG.
