The system is not the only source of WM_PAINT messages.The Invalidate Rect or Invalidate Rgn function can indirectly generate WM_PAINT messages for your windows.
Emotional invalidation is when a person’s thoughts and feelings are rejected, ignored, or judged.
Invalidation is emotionally upsetting for anyone, but particularly hurtful for someone who is emotionally sensitive.
Invalidation disrupts relationships and creates emotional distance.
When people invalidate themselves, they create alienation from the self and make building their identity very challenging.
This allows the user to change the figure by typing a number and view the results; these results are drawn as soon as there are no other messages in the application's message queue.
WM_PAINT: hdc = Begin Paint(hwnd, &ps); Get Client Rect(hwnd, &rc); Set Map Mode(hdc, MM_ANISOTROPIC); Set Window Ext Ex(hdc, 100, 100, NULL); Set Viewport Ext Ex(hdc, rc.right, rc.bottom, NULL); Polyline(hdc, ppt, cpt); End Paint(hwnd, &ps); In this example, the NULL argument used by Invalidate Rect specifies the entire client area; the TRUE argument causes the background to be erased.
If you do not want the application to wait until the application's message queue has no other messages, use the Update Window function to force the WM_PAINT message to be sent immediately.
If there is any invalid part of the client area, Update Window sends the WM_PAINT message for the specified window directly to the window procedure.
Most people would deny that they invalidate the internal experience of others.
Very few would purposefully invalidate someone else.
But well-intentioned people may be uncomfortable with intense emotions or believe that they are helping when they are actually invalidating. The truth is that validation is not self-acceptance, it is only an acknowledgement that an internal experience occurred.
