Ok, do any Active X control designers have an answer to this one?

I am designing a user control that needs to react when its parent form is resized.

I have tried to use the Ambient property but the resize event does not appear to be included?

I have had some success with using timers to continually check if the parents size has changed but this is messy code.

Does anyone know a way I can trap when the parent forms size changes without using a timer?
