win32: simulate a click without simulating mouse movement?

Question

I\'m trying to simulate a mouse click on a window. I currently have success doing this as follows (I\'m using Python, but it should apply to general win32):

Answer 1

Try WindowFromPoint() function:

POINT pt;
    pt.x = 30; // This is your click coordinates
    pt.y = 30;

HWND hWnd = WindowFromPoint(pt);
LPARAM lParam = MAKELPARAM(pt.x, pt.y);
PostMessage(hWnd, WM_RBUTTONDOWN, MK_RBUTTON, lParam);
PostMessage(hWnd, WM_RBUTTONUP, MK_RBUTTON, lParam);
