Explorer.BeforeMaximize event (Outlook)

Occurs when an explorer is maximized by the user.

Syntax

expression. BeforeMaximize( _Cancel_ )

expression A variable that represents an Explorer object.

Parameters

Name Required/Optional Data type Description
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 is not maximized.

Remarks

This event can be cancelled after it has started.

Example

The following Microsoft Visual Basic for Applications (VBA) example prompts the user with a warning message before maximizing the current window. If the user clicks Yes, the explorer will maximize. 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 Initialize_Handler() 
 
 Set myOlExp = Application.ActiveExplorer 
 
End Sub 
 
 
 
Private Sub myOlExp_BeforeMaximize(Cancel As Boolean) 
 
'Prompts the user before maximizing the explorer 
 
 
 
 Dim lngAns As Long 
 
 
 
 lngAns = MsgBox("Are you sure you want to maximize the current window?", vbYesNo) 
 
 If lngAns = vbYes Then 
 
 Cancel = False 
 
 Else 
 
 Cancel = True 
 
 End If 
 
 
 
End Sub
