Solution 2

The easiest way is to compile it to a dll. Assuming you aren't using the Express edition of VS, cerate a new project within your solution, and select "Other languages", "Visual C++", then either choose "MFC DLL" or "Class Library" depending on your original source requirements.

Once you build the DLL you should be able to invoke the functions from C#, using DllImport

You can create DLLs with Visual C++ Express, although not MFC.

OriginalGriff 2-Feb-12 5:13am

You can, but you have to have the C++ Express version not just the C# one he may have - only reason I mentioned it.
Doing it in the Express version is probably as simple, but it can't be a part of the C# solution - it has be be separate. Since I don't have the express versions, I can't guide him through that! :laugh:

Richard MacCutchan 2-Feb-12 5:26am

You are right of course, but since OP said they had C++ source I assumed they had the C++ Express as minimum.

OriginalGriff 2-Feb-12 5:34am

I was assuming the other way round! :laugh:

Richard MacCutchan 2-Feb-12 5:39am

My assumption was not the assumption that you assumed. :)

For creating DLL in VS you can refer here

http://msdn.microsoft.com/en-us/library/ms235636(v=vs.80).aspx[^]

And for calling these DLL functions in C# you can use p-invoke. Check here for more info

Write your C++ code into C++ Dll and call it in .net using DllImport Attribute. This link will help you to use it. http://msdn.microsoft.com/en-us/library/aa984739(v=vs.71).aspx[^]
