I don't want users to see the screen 'flicking' around as the code moves between cells and worksheets Any help gratefully recieved Dan Dan Auber Dan [email protected], The code to stop the screen updating is Application. Msg Box "Macro complete", vb OKOnly vb Information, "Title"Application.

Screen Updating = False Try it in combination with these lines: Application. Screen Updating = True Just some additional info: If you want to do this in VBA for Access, the command is: Do Cmd.

Recalculation occurs when- Edit a Cell- Open workbook – Add / Delete / Hide / Unhide row – Rename worksheet – Reorder worksheet – Change Calculation Mode from Manual to Automatic / rerun xl Calculation Automatic in VBA – Modify Named Range Types of Cells that will recalculate – Cells affected directly by the above actions – Cells indirectly affected by the above actions such as formula referencing to the affected Cells – Cells that contain volatile Functions recalculate every time when any of the above action is performed It is a common practice to temporarily turn Calculation Property from Automatic (xl Calculation Automatic) to Manual (xl Calculation Manual) in VBA to improve performance.

Excel & Word have the Screen Updating method thru which a developer can lock the main window from unnecessarily redrawing itself whilst the macro is being executed. If left alone, redrawing is not only ugly on the eyes it also takes more time for the macro to reach completion.
