    calling unmanaged c++ dll from c#

    I'm trying to call an unmanaged c++ dll from a c# windows form application, but I'm getting a DLLNotFoundException. The dll is in my project folder, and my code calling it is:

    Code:
    [DllImport("id3libBuilder.dll")]
    	private static extern void createMediaLibrary ( string src );
    I don't know why it can't find the dll. The code seems pretty straightforward. Can anyone help?

    I often encounter problems like this when I call a C++ DLL from Visual Basic. When this hppens, i just use the absolute path of the said dll.

    c:\project\finkus\sucks\myballs\andlikesit\verymuc h.dll

    or something like that

    It should work fine for C# too.
