win32 api mouse coordinates weird

Feb 10th, 2006

I'm writting a program where I need the coordinates of the mouse when it's clicked inside the client area. For some reason, the coordinates seem to be in base 21, maybe higher (I've seen the character k). I'm not sure why this is happening.

case WM_LBUTTONDOWN:
{
	int x = ((int)(short)LOWORD(lParam));
	int y = ((int)(short)HIWORD(lParam));

	char buf[20];
	string s = itoa(x, buf, 21);
	s += ", ";
	s += itoa(y, buf, 21);
	MessageBox(hwnd, s.c_str(), "Distance", MB_OK | MB_APPLMODAL);

	return 0;
}
