inspectors.NewInspector +=
new Outlook.InspectorsEvents_NewInspectorEventHandler(
Inspectors_NewInspector);
foreach (Outlook.Inspector inspector in inspectors)
{
TotalAttachSize = 0;
Inspectors_NewInspector(inspector);
}
}
void Inspectors_NewInspector(Microsoft.Office.Interop.Outlook.Inspector Inspector)
{
if (Inspector.CurrentItem is Outlook.MailItem)
{
Outlook.MailItem mail = (Outlook.MailItem)Inspector.CurrentItem;
mail.BeforeAttachmentAdd += new Microsoft.Office.Interop.Outlook.ItemEvents_10_BeforeAttachmentAddEventHandler(mail_BeforeAttachmentAdd);
mail.AttachmentAdd += new Microsoft.Office.Interop.Outlook.ItemEvents_10_AttachmentAddEventHandler(mail_AttachmentAdd);
}
}
void mail_AttachmentAdd(Microsoft.Office.Interop.Outlook.Attachment Attachment)
{
int MB = 1024*1024;
MessageBox.Show(Attachment.Size.ToString() + "\n" + " Now Total Size limit reached is " + TotalAttachSize/MB + " MB");
}
void mail_BeforeAttachmentAdd(Microsoft.Office.Interop.Outlook.Attachment Attachment, ref bool Cancel)
{
