If you work with workbooks first worked on by your colleagues, you may be frustrated by the zoom factor applied to those workbooks by those others. For instance, if your colleague (Wanda) has a huge monitor, it wouldn't be uncommon for her to reduce the Excel's zoom factor to 75% or even 60%. The purpose, of course, is so she isn't overpowered by things that look very large at the full zoom factor.
The problem is that the zoom factor is saved with the workbook. Thus, when Wanda saves the workbook and hands it off to you, when you open it, the workbook is still displayed at whatever zoom factor Wanda last used. If you don't have the same size monitor as Wanda, then the workbook may be almost illegible on your system.
There are only two possible solutions to this problem. First, you can simply adjust the zoom factor once you open the workbook. There are a multitude of ways to do this, but the easiest involves using the Zoom control at the right side of the status bar. You can click the centerpoint on the Zoom slider and quickly get back to 100%, or you can click the percentage beside the slider to display the Zoom dialog box.
The second workaround is to create a macro that gets saved with the workbook. The macro can run every time the workbook is opened, and thereby set the zoom factor. (This macro should be added to the This Workbook code window in the VBA editor.)
Private Sub Workbook_Open() ActiveWindow.Zoom = 100 End Sub
The only problem with a macro such as this, of course, is that whenever Wanda (your colleague) opens the workbook on her system, the zoom factor is also set and she'll get just as frustrated with you as you were with her.
Perhaps a solution is to create a more involved macro—one that checks the current screen resolution and then sets the zoom factor accordingly. For instance, the following macro could be used to make the adjustments based on resolution:
Declare Function GetSystemMetrics32 Lib "user32" _ Alias "GetSystemMetrics" (ByVal nIndex As Long) As Long Public Sub ScreenRes() Dim lResWidth As Long Dim lResHeight As Long Dim sRes As String lResWidth = GetSystemMetrics32(0) lResHeight = GetSystemMetrics32(1) sRes = lResWidth & "x" & lResHeight Select Case sRes Case Is = "800x600" ActiveWindow.Zoom = 75 Case Is = "1024x768" ActiveWindow.Zoom = 125 Case Else ActiveWindow.Zoom = 100 End Select End Sub
This routine checks the screen resolution and adjusts the window accordingly. Other resolutions and zooms may be added easily. To make the routine run automatically, just use a Workbook_Open event handler in the This Workbook code window to trigger the macro:
Private Sub Workbook_Open() ScreenRes End Sub
