Printing several files in the background without print options dialog!

[lehu]

How to automatically print several PDF-files in the background with the
default printer and without getting the print options dialogue ?

This code(snippet) gets one PDF-file printed, but I still get the print
options dialogue.

For Counter = 1 To UBound(MyList)
ShellExecute lnghWnd, Print, MyList(Counter), vbNullString, "D:\tmp\", SW_HIDE
Next

When for example MyList(1) = "Test1.pdf" and MyList(2) = "Test2.pdf" only
Test1.pdf gets printed...

Does anybody know how to prevent the print options dialogue from being
presented and how to make it work for several files?

Any help appreciated.
