Referencing a DLL Error

[ZeroEffect]

While I am trying to add a reference to a DLL I get this Message Box

A reference to 'C:\MyDLL.DLL' could not be added. This is not a valid assembly or COM Component. Only Assemblies with extention 'dll' and COM componets bcan be referenced. Please make sure that the file is accessible, and that it is a valid assembly or com component.

Is it possible to add a reference to this file?

Thanks for your help.

What language was the dll written in? You can only add references to either a COM dll or a .Net assembly - any other dll you would need to access via p/invoke.

Thanks for the extremely quick reply.

I thought it was .Net. I know it is not a COM dll. How does p/invoke work.

Too lazy to type - http://msdn.microsoft.com/msdnmag/issues/03/07/NET/ should get you going.
