BeforeViewSwitch Event

Occurs before the explorer changes to a new view, either as a result of user action or through program code. This event is not available in Microsoft Visual Basic Scripting Edition (VBScript).

Subobject**_BeforeViewSwitch(ByVal NewView As String, Cancel As Boolean)**

*object   * An expression that evaluates to an Explorer object.

NewView Required. The name of the view the explorer is switching to.

*Cancel    * Optional. False when the event occurs. If the event procedure sets this argument to True, the switch is cancelled and the current view is not changed.

Example

This Microsoft Visual Basic/Visual Basic for Applications (VBA) example confirms that the user wants to switch views and cancels the switch if the user answers No. The sample code must be placed in a class module, and the Initialize_handler routine must be called before the event procedure can be called by Microsoft Outlook.

Dim myOlApp As New Outlook.Application
Public WithEvents myOlExp As Outlook.Explorer

Public Sub Initialize_handler()
    Set myOlExp = myOlApp.ActiveExplorer
End Sub

Private Sub myOlExp_BeforeViewSwitch(ByVal NewView As Variant, Cancel As Boolean)
    Dim Prompt As String
    Prompt = "Are you sure you want to switch to the " & NewView & " view?"
    If MsgBox(Prompt, vbYesNo + vbQuestion) = vbNo Then Cancel = True
End Sub
