Hi Friends,
I am trying to convert plain c++ code int .dll file to be used in c# project. I recieve following message when I add reference to the *.dll (I have made from plain c++)
"A reference to 'D:\...\...\CLAHE.dll' could not be added. please make sure that the file is accessible, and a valid assemble or COM Component".
Please help how to do it.

No, you cannot do it. References only reference assemblies. To use unmanaged DLL you need to use P/Invoke via System.Runtime.InteropServices. See http://msdn.microsoft.com/en-us/library/system.runtime.interopservices.aspx[^].

You can find detailed explanation and basic code samples here: http://en.wikipedia.org/wiki/P/Invoke[^].

For more information, learn this:
http://msdn.microsoft.com/en-us/library/sd10k43k.aspx[^],
http://msdn.microsoft.com/en-us/library/26thfadc.aspx[^].

Some cases of [ImportDll] can be rather complex. If you're really lost, try to seek help at CodeProject and report all the details of the problem; in many cases we helped to find ends.
