Vba turn off screenupdating
You get several extra worksheet functions in Excel when you have ASAP Utilities installed.Some of the most asked questions that can be (or have been) solved by using ASAP Utilities.There are few absolute rules for optimizing VBA; you'll see the best increases in performance by streamlining the basic logic.Normally, Excel will recalculate a cell or a range of cells when that cell's or range's precedents have changed.Remember to set the Screen Updating property back to True when your macro ends.
This course introduces the Visual Basic for Applications programming language, covers creating subroutines and functions to hold code, and provides a solid grounding in the Excel 2007 object model.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. Remarks Turn screen updating off to speed up your macro code.
You won't be able to see what the macro is doing, but it will run faster.I am writing a script that loops through a folder and creates graphs from some criteria, and then exports these to powerpoint.
