Vba screen updating

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.Hence I created this generic wrapper to lock the window updates.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.Raise Number:=vb Object Error ERR_WINDOW_LOCK_FAIL, _ Description:="Unable to set a Power Point window lock" Exit Property End If Else ' Unlock the Window to refresh Lock Window Update (0&) Update Window (hwnd) hwnd = 0 End If End Property 'Sample Usage: Sub Long Processing Sub() ' Lock screen redraw Screen Updating=False ' --- Long time consuming code ' Redraw screen again Screen Updating=True ' Also see below article for another example of usage of the code End Sub It's fairly simple to open a Power Point file (*.ppt) for editing using VBA code however opening a Power Point Show (*.pps) file for editing is altogether another matter. Open method and it defaults to open the file in Slide Show mode. The routine below illustrates a manner of woring around the default behaviour and opening the file for editing. A VBA add-in to quickly insert any of the sample code found on our site directly into the Visual Basic Editor, save your own frequently used code, and more!Whenever you have a task to automate, you can usually go down the VBA route. Maybe later you add some features here-and-there, making your VBA code more powerful. Color = vb White End If i = i 1 Next cell ' offset i to alternate column coloring i = i 1 Next repeat Msg Box "Total time was: " & (Timer - start Time) End Sub Before moving on, let’s get a better understanding of why this is taking so long. Color = vb White End If i = i 1 Next cell ' offset i to alternate column coloring i = i 1 Next repeat Msg Box "Total time was: " & (Timer - start Time) Application.Display Status Bar = True ''//Make sure that the statusbar is visible For i = 1 To i Max ''// imax is usually 30 or so fraction Done = CDbl(i) / CDbl(i Max) Application.

It’s not as fast as it used to be and it can begin to get pretty frustrating waiting a long time for your code to finish. Color = vb Black Else ' else, color the cell light gray cell. If you think about it, if there were of the screen to process, it should run faster, right? Now it should make sense why it’s a good idea to turn off Public Sub Add Content To Sheet() Application. Color = vb Black Else ' else, color the cell light gray cell. Status Bar = Format(fraction Done, "0%") & "done..." ' or, alternatively: ' status Range.value = Format(fraction Done, "0%") & "done..." ' Some code.......Next i Sub Progress Meter() Dim boo Status Bar State As Boolean Dim i Max As Integer Dim i As Integer i Max = 10000 Application.The grater the amount of screen changes the bigger the impact will be. Other application settings that can make a difference to execution time are Calculation and Event handling. Enable Events = False ' Code here Clean Up: On Error Resume Next Application. Calculation = xl Calculation Automatic Application. Enable Events = True Exit Sub EH: ' Do error handling Go To Clean Up End Sub Sub test Screen Updating() Dim i As Integer Dim numb Switches As Integer Dim results As String 'swap between sheets this number of times numb Switches = 1000 'keep track of time Dim start Time As Double start Time = Time 'swap between sheets 1/2 (need both sheets or this will crash) For i = 1 To numb Switches Sheets(1 (i Mod 2)).Use this code template as a starting point (the error handler ensures that these properties are turned back on at the end of the sub, even if it errors) Sub Your Sub() On Error Go To EH Application. Select Next i 'get results results = "Screen Updating not disabled: " & Format(Time - start Time, "hh:mm:ss") & " seconds" start Time = Time 'scenario 2 - screenupdating disabled Application.Screen Updating = False ''//Turn off screen updating boo Status Bar State = Application.
