[BUG/PRB.] VFP 9.0 FIX - SET RESOURCE OFF AT STARTUP
January 2024
--------------------------------------------------------------
CCB
1. BUG:
Usually, VFP will open the resource file at startup.
If there is no the resource file, it will create the resource file.
But in some cases, for example,
VFP Runtime, VFP Multi-threaded Runtime,
usually we need not to create the resource file,
so we can set resource off at startup in these cases.
2. CAUSE:
There are some BUGs in the following code.
3. RESOLUTION:
We can write some code to fix the BUG.
