How to improve the email item selection event performance?

Hi,

I have noticed some issues with handling explorer change event when mailbox

is large. I have Outlook add-in which handles explorer change event like

below and displays senders name as a button caption which is created on

Outlook toolbar. It takes long sometimes to change the caption button.

Could you tell me how could I optimize the single email item selection event?

Thanks,

Paresh

My code:

Private WithEvents objExpl As Outlook.Explorer

Friend Sub InitHandler(olApp As Outlook.Application, strProgID As String)

Set objExpl = objOutlook.ActiveExplorer 'Explorer Object

End Sub

Private Sub objExpl_SelectionChange()

If objExpl.Selection.Count > 0 Then

For Each objMailItem In objExpl.Selection

If objMailItem.Class = olMail Then

msgbox "email item";

End If

Next

End If

End Sub
 
If you want to handle one item only, there's no need to loop through all the

collection. Instead, just work with Selection(1).

But I suppose what takes long is accessing the commandbar button, and that's

the code we don't see. If it's always the same button, keep its reference,

so you don't need to find it again and again.

Best regards

Michael Bauer
