Syntax

Example

This Visual Basic for Applications (VBA) example checks the size of the item after an attachment has been added and displays a warning if the size exceeds 500,000 bytes. The sample code must be placed in a class module such as ThisOutlookSession, and the TestAttachAdd() procedure should be called before the event procedure can be called by Microsoft Outlook.

Public WithEvents newItem As Outlook.MailItem 
 
 
 
Private Sub newItem_AttachmentAdd(ByVal newAttachment As Attachment) 
 
 If newAttachment.Type = olByValue Then 
 
 newItem.Save 
 
 If newItem.Size > 500000 Then 
 
 MsgBox "Warning: Item size is now " &; newItem.Size &; " bytes." 
 
 End If 
 
 End If 
 
End Sub 
 
 
 
Public Sub TestAttachAdd() 
 
 Dim atts As Outlook.Attachments 
 
 Dim newAttachment As Outlook.Attachment 
 
 
 
 Set newItem = Application.CreateItem(olMailItem) 
 
 newItem.Subject = "Test attachment" 
 
 Set atts = newItem.Attachments 
 
 Set newAttachment = atts.Add("C:\Test.txt", olByValue) 
 
End Sub
