Re: DLL and VB problems
Hello,
Please ignore my previous message; I made a mistake in the client C file.
I corrected it, and the C client calls the DLL perfectly.
But I tried calling from a VB client, and it works fine for the first
time; Running again causes the application to close.
Any insight would be greatly appreciated.
Thanks.
Paul
