Private Sub expression_BeforeMinimize(Cancel As Boolean)
expression An expression that returns one of the objects in the Applies To list declared with events in a class module.
Cancel Required Boolean. False when the event occurs. If the event procedure sets this argument to True, the operation is not completed and the explorer or inspector is not minimized.
Example
The following Microsoft Visual Basic/Visual Basic for Applications (VBA) example prompts the user with a message before the window is minimized. If the user clicks Yes, the explorer is minimized. The sample code must be placed in a class module such as ThisOutlookSession, and the Initialize_Handler() subroutine should be called before the event procedure can be called by Microsoft Outlook.
Public WithEvents myOlExp As Outlook.Explorer
Sub Initalize_Handler()
Set myOlExp = Application.ActiveExplorer
End Sub
Private Sub myOlExp_BeforeMinimize(Cancel As Boolean)
'Prompts the user before minimizing the Explorer
Dim lngAns As Long
lngAns = MsgBox("Are you sure you want to minimize the current window?", vbYesNo)
If lngAns = vbYes Then
Cancel = False
Else
Cancel = True
End If
End Sub
