Explorer.BeforeFolderSwitch event (Outlook)
Occurs before the explorer goes to a new folder, either as a result of user action or through program code.
Syntax
expression. BeforeFolderSwitch( _NewFolder_ , _Cancel_ )
expression A variable that represents an Explorer object.
Parameters
| Name | Required/Optional | Data type | Description |
|---|---|---|---|
| NewFolder | Required | Object | The Folder object the explorer is switching to. |
| Cancel | Required | Boolean | False when the event occurs. If the event procedure sets this argument to True, navigation is cancelled, and the current folder is not changed. |
Remarks
This event is not available in Microsoft Visual Basic Scripting Edition (VBScript).
If the folder being switched to is in a namespace that doesn't support automation (such as the file system), NewFolder is Nothing.
Example
This sample prevents a user from switching to a folder named "Off Limits". The sample code must be placed in a class module such as ThisOutlookSession, and the Initialize_handler routine must be called before the event procedure can be called by Microsoft Outlook. To run this example without errors, make sure a folder by the name 'Off Limits' exists in the folder displayed in the active explorer.
Public WithEvents myOlExp As Outlook.Explorer
Public Sub Initialize_handler()
Set myOlExp = Application.ActiveExplorer
End Sub
Private Sub myOlExp_BeforeFolderSwitch(ByVal NewFolder As Object, Cancel As Boolean)
If NewFolder.Name = "Off Limits" Then
MsgBox "You don't have permission to access this folder."
Cancel = True
End If
End Sub
