After all: I don't know C/C++ language, nor low-level COM, so this may be a crazy idea.

I know that VFP MTDLLs use Apartment model (STA), but on the other side the VFP9T.DLL is thread-safe, so I would question if anybody have tryed to change the threading model of a generated DLL to "Free" so can be used in MTA.

My reasoning is this:

1) If the VFP9T DLL is thread-safe (which as I understand it, means that support real multithread) and care is taken in the code for using only local variables (or properties) and properly marking "critical sections", then in theory no problems should happen.

2) If the VFP "multi-thread" concept really means "multi-thread STAs", on which ona STA can't se other STAs, then what's the support for critical section is for?

I'm going to do some testing, but I'm interested in other's testings on the matter.
Yeah, this may be crazy, but it doesn't hurt to make a try :)


Best Regards.-
