I am writing an ASP page and want to call a DLL to do some computation for me. How do i call a Dll from ASP? What sort of DLL do i need to produce

Hi, lgcoles

For information about creating (VB) DLLs, check out the following thread:

http://p2p.wrox.com/topic.asp?TOPIC_ID=193

The code I have posted deals with ADO data access, but the principle holds true for other kinds of DLLs as well.

Cheers,

Can you do the same with a C DLL

C or C++?

You can do the same with C++ (that is, create a DLL that can be called from an ASP page and that is hosted in a COM+ package), but I am not sure about C. AFAIK, C doesn't support COM+ so if that's true, I guess you're out of luck with C.

There may be others on this forum that can give a definite answer to this question....

Cheers,

99.99% sure you can't call a C DLL directly. You could, however, provide a COM object with a wrapper function that calls your C DLL.
