Chilkat VB.NET Downloads

VB.NET
' The AddHeaderField can be called to add any header field.
' If the header field already exists, AddHeaderField replaces it.
Dim email As New Chilkat.Email
email.AddHeaderField("X-Priority","3 (Normal)")

email.AddHeaderField("X-Priority","1 (High)")

email.AddHeaderField("X-Priority","5 (Low)")


' The X-Priority value ranges from 1 to 5, with 1 being 
' high priority, 3 is normal, and 5 is low.
' You may set X-Priority to the number alone:

email.AddHeaderField("X-Priority","1")

' Including extra text, such as (High), should not 
' affect how the header is interpreted.
email.AddHeaderField("X-Priority","1 (High)")
