Thus, the main body of your macro can do its work behind the scenes without the necessity of stopping to update the screen.

I am writing a script that loops through a folder and creates graphs from some criteria, and then exports these to powerpoint.
At the moment, creating 130 graphs takes 290 seconds, of which 286 are used by powerpoint. While I can alt-tab and keep powerpoint in the background, when switching to Powerpoint all the changes are being shown and you can basically see how it slows down the program. Should it be in a class module, should I do anything else or what am I doing wrong?
(Microsoft Word is the most popular word processing software in the world.) This tip (749) applies to Microsoft Word 97, 2000, 2002, and 2003.
You can find a version of this tip for the ribbon interface of Word (Word 2007 and later) here: Turning Off Screen Updating.
All those Screen Updating = False's you see is called "sheer desperation". I can still enter the workbook and it is screenupdating away even right after the line set it false. Screen Updating = False" in the immediate window it works as expected. Thanks Colin Correct, when you step through in debug mode the screenupdating remains turned on. To test it properly, try this: Put a commandbutton on your sheet and paste in Application. Net) | Coordinates, Vectors and 3D volumes I've experienced this problem, with code that previously worked!I suspect a major reason for this is not being able to turn off screenupdating for powerpoint. Below is the code-snippet I have borrowed and an example of how I try to call it: Option Explicit ' User Defined Error codes Const ERR_NO_WINDOW_HANDLE As Long = 1000 Const ERR_WINDOW_LOCK_FAIL As Long = 1001 Const ERR_VERSION_NOT_SUPPORTED As Long = 1002 ' API declarations for Find Window() & Lock Window Update() ' Use Find Window API to locate the Power Point handle.Declare Function Find Window Lib "user32" Alias "Find Window A" (By Val lp Class Name As String, By Val lp Window Name As Long) As Long ' Use Lock Window Update to prevent/enable window refresh Declare Function Lock Window Update Lib "user32" (By Val hwnd Lock As Long) As Long ' Use Update Window to force a refresh of the Power Point window Declare Function Update Window Lib "user32" (By Val hwnd As Long) As Long Property Let Screen Updating(State As Boolean) Static hwnd As Long Dim Version No As String ' Get Version Number If State = False Then Version No = Left(Application. Version, ".") - 1) 'Get handle to the main application window using Class Name Select Case Version No Case "8" ' For PPT97: hwnd = Find Window("PP97Frame Class", 0&) Case "9" ' For PPT2K: hwnd = Find Window("PP9Frame Class", 0&) Case "10" ' For XP: hwnd = Find Window("PP10Frame Class", 0&) Case "11" ' For 2003: hwnd = Find Window("PP11Frame Class", 0&) Case "12" ' For 2007: hwnd = Find Window("PP12Frame Class", 0&) Case "14" ' For 2010: hwnd = Find Window("PPTFrame Class", 0&) Case Else Err.Raise Number:=vb Object Error ERR_WINDOW_LOCK_FAIL, _ Description:="Unable to set a Power Point window lock" Exit Property Else Lock Window Update (hwnd) End If Else 'Unlock the Window to refresh Lock Window Update (0&) Update Window (hwnd) hwnd = 0 End If End Property Sub Test Sub() ' Lock screen redraw If Screen Updating Off = True Then Screen Updating = False ' --- Loop through charts in Excel and export them to Powerpoint ' Redraw screen again Screen Updating = True End Sub How do I do this? I tried copying all the code above into a class module and then added Set Screen Updating = New Screen Updating in my regular module, to no avail. EDIT: Just use the code as it was originally written: no need to add anything.The bad news is that it doesn't make any difference to speed in my testing in PPT 2013.
