    Maybe the TrackMouseEvent function

    Ok, this is my code:
    Code:
    LRESULT CALLBACK WndProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
    {
    	static BOOL bLeave;
    	switch (uMsg)
    	{
    	case WM_CREATE:
    		{
    			return 0;
    		}
    	case WM_COMMAND:
    		{
    			return 0;
    		}
    	case WM_CLOSE:
    		{
    			DestroyWindow(hWnd);
    			return 0;
    		}
    	case WM_MOUSEMOVE:
    		{
    			TRACKMOUSEEVENT tme;
    			tme.cbSize = sizeof(TRACKMOUSEEVENT);
    			tme.dwFlags = TME_LEAVE|TME_HOVER;
    			tme.dwHoverTime = HOVER_DEFAULT;
    			tme.hwndTrack = hWnd;
    			_TrackMouseEvent(&tme); // WindowFromPoint
    
    			if (bLeave) {
    				POINTS pMouse;
    				char szMouse[24];
    
    				pMouse = MAKEPOINTS(lParam);
    				wsprintf(szMouse, "%i, %i", pMouse.x, pMouse.y);
    				SetWindowText(hWnd, szMouse); // display the mouse points
    			}
    			return 0;
    		}
    	case WM_MOUSEHOVER:
    		{
    			bLeave = FALSE;
    			return 0;
    		}
    	case WM_MOUSELEAVE:
    		{
    			bLeave = TRUE;
    			return 0;
    		}
    	case WM_DESTROY:
    		{
    			PostQuitMessage(0);
    			return 0;
    		}
    	}
    	return DefWindowProc(hWnd, uMsg, wParam, lParam);
    }
    My idea is that display the points only when the mouse is outside of my window, but instead it showed when is inside, any ideas?
