Getting Excel to refresh data on sheet from within VBA

Question

How do you get spreadsheet data in Excel to recalculate itself from within VBA, without the kluge of just changing a cell value?

Answer 1

I had an issue with turning off a background image (a DRAFT watermark) in VBA. My change wasn't showing up (which was performed with the Sheets(1).PageSetup.CenterHeader = "" method) - so I needed a way to refresh. The ActiveSheet.EnableCalculation approach partly did the trick, but didn't cover unused cells.

In the end I found what I needed with a one liner that made the image vanish when it was no longer set :-

Application.ScreenUpdating = True
