[BUG/PRB.] VFP 9.0 FIX - SAVING THE SETTING OF SET COLLATE TO MACHINE
January 2024
-------------------------------------------------------------------------------
CCB
1. BUG:
In vfp9 (and vfp6, vfp7, vfp8), we can save the current settings in the Windows registry:
Tools --> Options --> Set As Default
For VFP 9.0, the current settings will be saved in the key HKEY_CURRENT_USER\Software\Microsoft\VisualFoxPro\9.0\Options.
For VFP Advanced 32-bit, the current settings will be saved in the key HKEY_CURRENT_USER\Software\Microsoft\VisualFoxPro\10.n\Options.
For VFP Advanced 64-bit, the current settings will be saved in the key HKEY_CURRENT_USER\Software\Microsoft\VisualFoxPro64\10.n\Options.
But for the setting of SET COLLATE TO "MACHINE", it will not be saved in the Windows registry (in fact, it will be saved as an empty string).
2. CAUSE:
There are some BUGs in the following code.
3. RESOLUTION:
We can write some code to fix the BUG.
