Steve,

If you have Visual Studio there is a sample app on my website in spyin.zip to show how to create and use a VC++ DLL from VFP. It's much, much easier that the gyrations you heve to use for the older style of FLLs.

>Well, it gets better. Not only do the several DLL functions require a pointer to the address space, they also want the size. I also believe several K of memory needs to be allocated because many of the functions cache info in this buffer as you call certain functions. This info can build up (to what extent, I don't know, I'm still trying to get past the initialization!).

I should be able to call a function in an FLL to allocate the memory, and have it return the pointer to the memory and the size of memory allocated. I should then be able to use these numbers in my app to call the functions in the custom DLL. I could use that same DLL to deallocate the memory (if for some reason it can't be deallocated from my app with globalunlock() and globalfree()). How does that sound? If VFP had a pointer type, I wouldn't have to go through any of this trouble (GlobalLock() requires a pointer type arg).
