Hi,

 

Im trying to figure out how can i repaint a remote window in delphi easily, because if i make changes to the window, i always have to minimize and maximize it to take effect. (believe the paint message start going when i maximizing).

 

Is there any workaround? I have read that i should use the invalidate function, but i dont have a clue how to do it on a specific window, outside delphi.

 

You can use the InvalidateRect API for Windows:

Just give it a valid handle to the window and use 0 / null for the rest of the parameters to force the entire window to refresh.

 

You can use API like FindWindow to get the hWnd needed for InvalidatedRect.
