I removed the "Entry point"  and I got errors "Object reference not set to an instance of an object."

This is the Code:

[DllImport("iaxclient.dll")]	public extern static int			iaxc_register([MarshalAs(UnmanagedType.LPStr)]string iaxc_user,
			[MarshalAs(UnmanagedType.LPStr)]string iaxc_pass,
			[MarshalAs(UnmanagedType.LPStr)]string iaxc_host);
		
private void button1_Click(object sender, System.EventArgs e)
	{
		iaxc_register("1807","1807","82.201.196.147");			
			
	}

Remove the 'EntryPoint=' section from your DllImport attribute.

Note that the DLL is not an "unmanaged com object". It is a plain win32
library.
