Hi Leigh

Code: Select all

oPrinter := RpPrinter{oWindow, SELF}
oPrinter:PrintPreview("Job", "File", "Caption", "Message", TRUE, FALSE, FALSE, SW_SHOWNORMAL, ZOOM_100, #rpPrintPreviewDLG)

gives following error

Code: Select all

Invalid Print Preview Object: RPPRINTPREVIEWDLG
Object of type 'ReportPro2.RpPrinter' cannot be converted to type 'XSharp.__Usual[]'.
CallStack: 
RPTSUMMEN:.CTOR (41)

#PreviewDlg instead of #rpPrintPreviewDLG if you are using the PreviewDlg class.

Hi Leigh,
and if I want to use standard dialog?
With #PreviewDlg instead of #rpPrintPreviewDlg I get similar message:

Code: Select all

The following error was encountered while reporting: 
Invalid Print Preview Object: PREVIEWDLG

// here you can delete the default buttons

RETURN SELF
END CLASS

Ah, we are using ReportPro2.RpReportRDD{} rather than RpPrinter{} - maybe that is the issue?

[lagraf]

My ReportProRDD and ReportProSQL reports are not the problem, they do well.
This is a problem using RpPrinter, you see it in the class init and in the error message.

Franz, did you have any problems when you specified NULL_SYMBOL for this param?

[lagraf]

Hi Chris,
if I use NULL_SYMBOL rpPrinter crashes with

Code: Select all

The following error was encountered while reporting: 
Invalid Print Preview Object: 
Object of type 'ReportPro2.RpPrinter' cannot be converted to type 'XSharp.__Usual[]'.
CallStack: 
RPTSUMMEN:.CTOR (36)
...

If I use #rpPrintPreviewDlg the message is nearly the same

Code: Select all

The following error was encountered while reporting: 
Invalid Print Preview Object: RPPRINTPREVIEWDLG
Object of type 'ReportPro2.RpPrinter' cannot be converted to type 'XSharp.__Usual[]'.

Hi Franz,

It is a little strange judging from the error message. Can you please show us your exact code?

[lagraf]

Code: Select all

LOCAL oPrinter AS RpPrinter
oPrinter := RpPrinter{oWindow, SELF}
IF oPrinter:IsValid
	oPrinter:Landscape := FALSE
	oPrinter:UnitOfMeasure := UNIT_MM
	oPrinter:BottomMargin := 0
	oPrinter:LeftMargin := 0
	oPrinter:RightMargin := 0
	oPrinter:TopMargin := 0
	oPrinter:NoPageNums := TRUE
	oPrinter:NoSelection := TRUE
	oPrinter:SetFont("Arial", 10, FALSE, FALSE, FALSE)
	oPrinter:SetPrinterByName("SCREEN", "")
	oPrinter:PaperSize := DMPAPER_A4
	oPrinter:PrintPreview("Tagessummen", "SUMMEN.PRN", "Tagessummen", "Ausdruck in Bearbeitung ...", TRUE, FALSE, FALSE, SW_SHOWNORMAL, ZOOM_100, NULL_SYMBOL)
ENDIF

Hi Franz,

So the line 36 (and 37 in the other error message) that is mentioned in the callstack is the line that contains the call to PrintPreview()? Or is it pointing somewhere else?

I tested your exact code with a test report of mine and it seems to be working fine here. This means that the problem is happening due to some other part of the code that we do not see, or that this is not causing a problem anymore because of the many fixes I have made in our internal version. I will send you tonight our newest version of RP2, hope it fixes the problem. If not, please provide a full compileable sample that reproduces the error.
