how do i send a function that is inside a class to an API call? i need to know so that i can determin if the mouse is over the taskbar or not.

class functions are the same as any normal function when it comes to their return result.

ie.

begin
APICall(IntToStr(99));
end;

is the same as:

begin
APICall(Form1.Memo1.Lines.Text);
end;

Yeah, but it doesn't work. It generates a error.

The problem would then seem to be that the API function you're calling is expecting different data passed to it. Show us your code snippet that's causing the problem.

well, the following codes doen;t work

PrevWndProc := SetWindowLong(hWnd, GWL_WNDPROC, TTaskbar.WindowProc);
PrevWndProc := SetWindowLong(hWnd, GWL_WNDPROC, WindowProc);
PrevWndProc := SetWindowLong(hWnd, GWL_WNDPROC, @TTaskbar.WindowProc);
PrevWndProc := SetWindowLong(hWnd, GWL_WNDPROC, @WindowProc);

When i pass the function, it says that there isn;t enough actual perameters. When i pass it as a pointer, it says it can't convert a pointer to a int (thus it shouldn't be a pointer, arnt they longints?). Anyways, I do have the function declared under the private section of the class and I written it too...
