>When I work with regular strings (LPTSTR), I have no problem modifying and returning the string. But when I tried to modify an array of strings (LPTSTR *), well, there is something I am missing. So maybe just my declaration isn't correct in VB, or maybe the way I'm declaring it on the C side isn't correct either.

I really am not sure, but could you pass ByRef Str1 as Variant?
