redraw/refresh dialog

[r0n]

Is there a way to redraw/refresh the dialog?
Is this also applicable to a dialog control?

I have a situation where I disable/enable a menu item trough:

Code:

Copy      Help

EnableMenuItem hm 500  MF_GRAYED / MF_ENABLED

But the dialog does not update itself to reflect the disabled/enabled menu item.
(only when you attempt to click on the menu item it update itself).
That's why I want to redraw/refresh dialog (or the control itself).
