                      VFP 9.0 FIX - SAVING THE SETTING OF SET COLLATE TO MACHINE

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, the current settings will be saved in the key HKEY_CURRENT_USER\Software\Microsoft\VisualFoxPro\10\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.

     ; 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, the current settings will be saved in the key HKEY_CURRENT_USER\Software\Microsoft\VisualFoxPro\10\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).
