pointers..?

[Magiaus]

is there a better way for me to initialize retPoint in the code below? My original code did not have two point structs but it crashed do to a null refreance when it ran. Why?

		void CursorPos(System::Drawing::Point *lpPoint){
			POINT iPoint;
			LPPOINT retPoint = &iPoint;
			GetCursorPos(retPoint);
			lpPoint->X=retPoint->x;
			lpPoint->Y=retPoint->y;
		}

See the changes. retPoint is only a pointer anyway, not a full struct, and you don't need it.

I should have thought of that....

And the last two lines are invalid too (now that lpPoint is gone) and should be removed.

I get what you mean bu the last two are still right because i am superclassing the GetCursorPos API for use in vb.net or C# and it passes the equiv type out I am going to chang it to a return though i think
