This is exactly what i want to know too.

 It seems simple enough...

I tried 2 things. First i tried this;

Dim Doc As New Infragistics.Documents.Report.Report
Dim Mem As New IO.MemoryStream
PrintDoc.SaveAsBinary(Mem)
Doc.Load(Mem)

That works up until Doc.Load, where it fails and says 'Root element is missing.'

 The second thing i tried was this;

Dim Doc As New Infragistics.Documents.Report.Report
PrintDoc.SaveAsXml("C:\Test.xml")
Doc.Load("C:\Test.xml")
Doc.Publish("C:\1.pdf", Infragistics.Documents.Report.FileFormat.PDF)

That appeared to work, except the xml file contained hardly any data and thus the pdf was only 1kb and would not open "This file cannot be opened because it has no pages."

 The contents of the xml document (which doesnt appear to contain any of the information about the appointments on the daily overview) is this;

 I don't beleive there's any wa to do this. You should  Submit a feature request to Infragistics.
