Description

Processes any pending paint messages immediately.

Call Update to force the control to be repainted before any more, possibly time-consuming, processing takes place. Use Update to provide immediate feedback to the user that cannot wait for the Windows paint message to arrive.

Update does not invalidate the control, but simply forces a repaint of any regions that have already been invalidated. Call Repaint instead to invalidate the control as well.
