I'm not an experienced SQL or VB-programmer. I can programm basic things in VBA and can read VBS and VB-programms

Now I have to send a PDF-file to a lot of people in a SQL-table, based on customergroup

Making a selection is no problem but how do I send this mail ? Is there some code available that I can use ?

Thanks in advance

Lookup Microsoft MAPI controls

You basically...
open mapi session
create mapi message
attach PDF
Call message's Send method
