hi, im trying to create a delagte for my async socket program but i cant
figure out how to create the async delegate for it. heres what i have so
far...
AsyncCallback * conasync = new AsyncCallback(0, this->ConnectCallBack);
heres my error:
x:\User\FinalProject\Battleship\NewGame.h(158): error C3351:
'System::AsyncCallback' : if you pass a NULL object instance to a delegate
constructor you must also pass the address of a static member function
it was very simple in VB but im seeing now its not quite as simple in
C++...if anyone can help me out thatd be great.
thanks

I would have thought it was this:
new AsyncCallback( this, ClassName::ConnectCallBack ) ;

It'd be 0 if the callback is static, or 'this' if it's not static.
