How do you get the location, in x-y coordinate pixels, of a mouse click?

Question

In C++ (WIN32), how can I get the (X,y) coordinate of a mouse click on the screen?

Answer 1

Assuming the plain Win32 API, use this in your handler for WM_LBUTTONDOWN:

xPos = GET_X_LPARAM(lParam); 
yPos = GET_Y_LPARAM(lParam);

Answer 2

You can call GetMouseMovePointsEx to get the mouse position and history. Alternatively, if you have access to your wndproc, you can just check the lparam of WM_MOUSEMOVE, WM_LBUTTONDOWN or similar message for the x,y coordinates.
