I never used LCK. If I write a DLL, I prefer it to be useable from any other tool that can use DLLs.

>The Library Construction Kit included with VFP allows you to pass arrays of double, integer, etc using the functions included in the LCK. I can successfully create a .DLL without MFC and pass arrays by reference. When I try to incorporate the LCK with an MFC based .DLL I get linker errors.
