Sample Visual Basic Procedure
Sub ChangeView

' The smallest percentage you can use is 10%. Const MinViewPercent As Long = 10

' The largest percentage you can use is 400%. Const MaxViewPercent As Long = 400

' Stores the results of the MsgBox selection. Dim lResult As Long

Dim lCurrentViewPercentage As Long Dim lNewViewPercentage As Long

' Get the current view percentage. lCurrentViewPercentage = ActiveWindow.View.Zoom

' Calculate a new view by dividing the old view by 2. lNewViewPercentage = (lCurrentViewPercentage / 2)

' Check to see if OK to change the percentage. If you apply a view ' percentage less then 10, a run-time error results. This code ' ensures a valid zoom is assigned. If lNewViewPercentage >= MinViewPercent Then

' Assign the calculated percentage to the zoom percentage. ActiveWindow.View.Zoom = lNewViewPercentage

Else

' If percentage goes out of range set to minimum level. ActiveWindow.View.Zoom = MinViewPercent

End If

' See whether a change was made to the zoom percentage. If lCurrentViewPercentage = ActiveWindow.View.Zoom Then

' No change was made. MsgBox "No change was made. Your zoom percentage is already " _ & "set to the minimum percentage.", vbInformation, _ "Minumin Already Set"

Else

' A change to the zoom percentage was made. ' Option to restore the original zoom percentage. lResult = MsgBox("The zoom percentage was changed to " _                  & ActiveWindow.View.Zoom & "%. " _                   & "Do you want to restore your original " _                   & "zoom percentage of " & lCurrentViewPercentage _                   & "%?", vbYesNo, "Restore Original Percentage")

' See whether they clicked the Yes button. If lResult = vbYes Then ActiveWindow.View.Zoom = lCurrentViewPercentage End If

End If

End Sub
