Hi!
Try to contact the Support for the Thirdparty DLL you want to use. They will help you. Probably a Patch is available.
If not, describe the problem in VFP code like:
DECLARE INTEGER funktion IN THIRDPARTYDLL AS funktion
RELEASE DLLS &&HERE YOU WILL GET An ERROR

You'll never notice the good things if you haven't seen the bad.
