Finally after several days with many problems I made my VB6 app send faxes through MS fax printer on the server and get the status of each job.
I used FaxComExLib.
Now when objDocument.ConnectedSubmit methot is called the application associated with the type of the document is invoked. In my case it's MS Word (I'm faxing only Word documents). I would like to make it invisible along with messages displayed during conversion.
Is there any way to do that?

Thank you
