Dll help

Question

Hey I'm trying to write a dll which can receive input from mIRC. In mIRC helpt its specified that i need a method with the following signature: int __stdcall procname(HWND mWnd HWND aWnd char *data char *parms BOOL show BOOL nopause) How do I convert that c++ signature into a c# method ? Thanks

If that function is contained in a dll called mIRC.dll let's say then I'd try this signature: using System.Runtime.InteropServices; [DllImport(mIRC.dll)] public static extern int procname(IntPtr mWnd IntPtr aWnd string data string parms int show int nopause); There should be no need to specify the _stdcall calling convention as that is the default in C#. You might be able to use 'bool' rather than 'int' for the last 2 parameters but I'm always a bit nervous of using the former (1 byte in C#) as BOOL in C is a typedef for a 4 byte integer.
