Thanks for your reply,

But with VFP 6.0 pro it does not work. LOCAL lnTest AS Integer would define 3 vars: lnTest, AS and integer! I can assign a value of other type. Same behavior when calling the activeX. One year ago I put my VB CD an books in the trash. Now I need it so, I try to avoid it but maybe l'll have to use it again.

If you or somebody else has another suggestion, I'll take it.
Thanks.
