Yes.

The class work as well:

Local oReport
oReport = CreateObject("MyReportClass")
oReport.PDFFileName = "xxxx.pdf"
oReport.Add("Repor1.frx")
oReport.Add("Repor2.frx")
oReport.Add("Repor3.frx")
oReport.Run("I")

The parameter passed in Run method could be "I" to print, "P" to preview, "E" to e-mail or "W" to upload the resultant pdf file.

In "MyReportClass" there is a Report Form... Object command for each report added that use a ReportListener object in which I add the watermarks and do another things.

I want that when the user choose the printer and the range of pages (using my form and don't the VFP print dialog), he also choose the number of copies.
But I want to do this in a way (if is possible) that I only need to change the class in itself instead of each call.
