> There was an article in the April 1997 FoxPro Advisor titled "Create Visual Header and Cursor Subclasses" which you might get some useful snippets of info from. Of the Reserved1-8 fields it only references Reserved3 which it describes as a list of class members. It also gives some details of some of the other 'named' fields (class, baseclass, objname, properties & methods).

Thanks Craig, you don't have to go through all the trouble of typing in the article, though. I've figured out most of the fields--Reserved3 is actually property and method descriptions. In any case, I'll post my findings and then maybe other people can fill in the few holes I have.

Right now, I'm still unsure about:

Platform : I think it is only "Windows" or "Comment"
Uniqueid : This is the time and date, but it has been transformed. Don't know how to read it properly.
Ole & Ole2: References any OLE objects?? Guess this will be changed in VFP6 to ActiveX 1 and ActiveX2 ;)
Reserved4 : I haven't found any case it's used in my VCX's.
Reserved5 : " "
Reserved8 : " "
User : " "


Anyone know the purpose of these fields?
