Invokation of Form.Paint

[Guest]

Hi,

Is there a way like in MFC's InvalidateRect function to call some function
that in turns will fire a forms Paint event. The Paint event is fired
automatically when you e.g. rezise your form - can you invoke this call
manually if the basis of what needs to be painted is altered.

best regards
Jesper

Yes, use just Form.Invalidate(Rectangle)

There's also Update() method which you might need to call to force the
painting to occur.
