Ms access vba turn off screenupdating Real free chatline for phone sex no creditcard needed
Christian Mark - you just beat me to it but as a fellow Celt any chance you could help me out with a fairly tricky problem ??I have a VB app that neds to read a variable entered by a user, access an Access database and read some information from it based on the entered variable.I suspect this is because the code is run through Excel (maybe I should have been more clear on that). I use a form to run a few codes on a database in Access.Raise Number:=vb Object Error ERR_NO_WINDOW_HANDLE, _ Description:="Unable to get the Power Point Window handle" Exit Property End If If Lock Window Update(hwnd) = 0 Then Err.
However, it never seems to actually call this function?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 "15" ' For 2013: hwnd = Find Window("PPTFrame Class", 0&) Case Else Err.Raise Number:=vb Object Error ERR_VERSION_NOT_SUPPORTED, _ Description:="Newer version." Exit Property End Select If hwnd = 0 Then 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.
