How are you creating the PDF? Is this via code, or just printing to Acrobat
or CutePDFWriter or some other PDF creator.
I'm not sure if there is a way to do it directly, but if your report has a
Caption, the Acobat print engine is likely pulling from the Caption, not the
report name itself. My poor-man's solution might be to do this just before
opening the print dialog:
Me.Caption = ExportName 'where ExportName contains the value you want
Acrobat to use for the file name.
Then change the Caption back after the print.
There is probably a more sophisticated way.
