[ENHANCED] VFP 9.0 FIX - THE FILE TYPE OF THE VISUAL C++ RUNTIME LIBRARY OF THE COMPILED EXECUTABLE FILES
January 2024
-------------------------------------------------------------------------------------------------------------------
CCB
1. BUG:
We can set the Visual C++ runtime library of the compiled executable files to MSVCR70.DLL, MSVCR71.DLL, MSVCR100.DLL, MSVCR10064.DLL or MSVCRA64.DLL,
it is useful for saving the 32-bit executable files and the 64-bit executable files in the same folder.
2. CAUSE:
There are some BUGs in the following code.
3. RESOLUTION:
We can write some code to fix the BUG.
