I have learned that the BeforeFormShow event is called with each new Inspector window, however it is only called once when the Explorer (or reading pane) is opened the first time and never again. I want to call the BeforeFormShow event in the ADXForm with each new AdxOutlookAppEvents.ExplorerSelectionChange. How can I accomplish this?
In the AddinModule I have:
Private Sub adxOutlookEvents_ExplorerSelectionChange(ByVal sender As System.Object, ByVal explorer As System.Object) Handles AdxOutlookAppEvents1.ExplorerSelectionChange
Debug.Print("The ExplorerSelectionChange event has occurred.")
Dim theExplorer As Outlook.Explorer = TryCast(explorer, Outlook.Explorer)
If theExplorer IsNot Nothing Then
Dim selection As Outlook.Selection = Nothing
Try
selection = theExplorer.Selection
Catch
End Try
If selection IsNot Nothing Then
ConnectToSelectedItem(selection)
Marshal.ReleaseComObject(selection)
End If
End If
'''''
GloMsgID = GetEmailHeader()
If GloMsgID.Contains("Foo") Then
'*** 'This should call ADXOlForm.BeforeFormShow for the Explorer window. I cannot find a method to fire the form to close, open or update for each new selection in the Explorer. I need to hide/show the form based on criteria.
End If
End Sub
Private Function GetEmailHeader() As String
Dim explorer As Outlook._Explorer = Nothing
Dim selection As Outlook.Selection = Nothing
Dim mailItem As Outlook._MailItem
Dim item As Object = Nothing
Dim headerText As String = String.Empty
Try
explorer = OutlookApp.ActiveExplorer()
'Explorer.Selection fires an exception for a top-level folder
selection = explorer.Selection
item = selection.Item(1)
If TypeOf item Is Outlook._MailItem Then
mailItem = CType(item, Outlook._MailItem)
If Me.HostMajorVersion >= 12 Then ' Outlook 2007 and higher
' use late binding
Dim propertyAccessor As Object = Nothing
propertyAccessor = mailItem.GetType().InvokeMember( _
"PropertyAccessor", Reflection.BindingFlags.GetProperty, Nothing, mailItem, New Object() {})
headerText = propertyAccessor.GetType().InvokeMember( _
"GetProperty", Reflection.BindingFlags.InvokeMethod, Nothing, propertyAccessor, _
New Object() {"http://schemas.microsoft.com/mapi/proptag/0x007D001E"}).ToString()
Marshal.ReleaseComObject(propertyAccessor)
End If
End If
Catch
Finally
If explorer IsNot Nothing Then Marshal.ReleaseComObject(explorer)
If selection IsNot Nothing Then Marshal.ReleaseComObject(selection)
If item IsNot Nothing Then Marshal.ReleaseComObject(item)
End Try
Return headerText
End Function

Hello Lance,

The forms manager only create a form instance once: before the form instance is embedded in an Outlook window (inspector or explorer). On the other hand, the ADXBeforeFormShow event is fired before the form is shown. That is, if the form is hidden via ADXOlForm.Hide() and you call ADXOlForm.Show, you'll get the ADXBeforeFormShow event.
Could you please explain what you need to achieve?
