Occurs when a Microsoft Outlook item is being opened in an Inspector. When this event occurs, the Inspector object is initialized but not yet displayed. The Open event differs from the Read event in that Read occurs whenever the user selects the item in a view that supports in-cell editing as well as when the item is being opened in an inspector.
Subobject**_Open(Cancel As Boolean)**
*object * An expression that evaluates to one of the objects in the Applies To list. In VBScript, use the word Item.
Cancel Optional (not used in VBScript). False when the event occurs. If the event procedure sets this argument to True, the open operation is not completed and the inspector is not displayed.
In Microsoft Visual Basic Scripting Edition (VBScript), if you set the return value of this function to False, the open operation is not completed and the inspector is not displayed.
This Visual Basic for Applications (VBA) example uses the Open event to display the "All Fields" page every time the item is opened.
Public WithEvents myItem As Outlook.MailItem Sub Initialize_handler() Set myItem = Application.Session.GetDefaultFolder(olFolderInbox).Items(1) myItem.Display End Sub Private Sub myItem_Open(Cancel As Boolean) myItem.GetInspector.SetCurrentFormPage "All Fields" End Sub
This Visual Basic for Applications example uses the Unread property to detect whether the item has been previously read. If it has, then it asks if the user wants to open it. If the user answers No, the return value is set to False to prevent the item from opening.
Public WithEvents myItem As Outlook.MailItem Sub Initialize_handler() Set myItem = Application.Session.GetDefaultFolder(olFolderInbox).Items(1) myItem.Display End Sub Private Sub myItem_Open(Cancel As Boolean) Dim mymsg As String If myItem.UnRead = False Then mymsg = "You have already read this message. Do you want to open this message again?" If MsgBox(mymsg, 4) = 6 Then Cancel = False Else Cancel = True End If End If End Sub
