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
