    instanciate an unmanaged class in a Winfows Form

    Hello,
    I like to use an unmanaged class in a Windows Form, when including its header, and entring the following code
    Code:
    #pragma endregion
     
    	private: PacketAfdx *P;
     
    		private: System::Void Form1_Load(System::Object^  sender, System::EventArgs^  e) 
    			 {
    				P->traficCapture();
     
    			 }
    I have this error message
    Code:

    Does this help: http://social.msdn.microsoft.com/For...b-e8d895a9faec? (It was the first hit of an MSDN search for servprov.h. )
    I was thrown out of college for cheating on the metaphysics exam; I looked into the soul of the boy sitting next to me.

    This is a snakeskin jacket! And for me it's a symbol of my individuality, and my belief... in personal freedom.
