Re: Difference between wodSmtp1.SendMessage and w (General questions)
Hi,
The difference is that SendSimple and SendSimpleAttachment will automatically create a Message object for you.
SendMessage on the other hand expects that you already created one by yourself.
In other words, you are receiving this error, because wodSmtp.Message object isn't populated (Sender atually isn't specified).
Hope this helps.
Regards,
