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
