Hi, I have coded few methods in C++ language. These methods are to be used in C#.NET . I guess I need to convert the .CPP file(C++ code) into DLL and then import the methods in C#. I made a Win32 project and converted the exe(C++ code) into unmanaged C++ DLL. Then I tried to call its method in C#.NET as : using System.Runtime.InteropServices; public partial class CDLL : System.Web.UI.Page { [DllImport("C:\\Project1\\TestProject\\Debug\\TestProject.dll", EntryPoint = "testMethod", ExactSpelling = false, CallingConvention = CallingConvention.Cdecl)] public static extern void testMethod(); protected void Page_Load(object sender, EventArgs e) { testMethod(); } } After running the above code i am getting error like : Unable to find an entry point named 'testMethod' in DLL 'C:\Project1\TestProject\Debug\TestProject.dll'. Can any one suggest how to run the above code successfully. Thanks.
