Description

Sets whether or not callbacks should be invalidating portions of the screen that are being changed. This should be used if you need to create temporary objects for calculation purposes and do not want the screen to be redrawn as a result.

Note: as of version 9.0, SetCallBackInval now also turns worksheet and worksheet image updating on and off. Use ResetObject to force a redraw of a worksheet or worksheet image.
