How to load the DLL in visual studio.net

[Guest]

Hi, all,

I have a DLL file (which wrote from Visual C++) and it could send signalling
message to the other server. I would like to write a ASP.net web page, and
have button to call the function in DLL to send message. Does anyone know how
tobload that DLL in ASP.net page?

I try "Add Reference", but I got the following message:
"This is not a valid assembly or COM component.Only assemblies with
extension 'dll' and COM components can be referenced. Please make sure that
the file is accessible, and that it is a valid assembly or COM component."

Thanks

Angie

This is true; you were adding it as if you were using COM interop, where
you create a .NET wrapper around the COM-dll call. You are looking at
adding a call to an external library, here's a short intro:

Alot more info can be found on MSDN elsewhere as well.
