Problem using ReportPro2 for X#

[vzeljko]

I'm new user of X# and ReportPro2 for X#.

I put this statements first

USING VO
USING ReportPro2
USING ReportPro2_Base
USING ReportPro2_Runtime
USING VOGUIClasses
USING VOWin32APILibrary

after using this code
oReport := RpReport{SELF, cRptPath + cRpt, cDBFPath}
IF oReport:IsValid
oReport:PrintPreview (cJobName, cPrint2FileName, cCaption, cMessage, TRUE, SW_SHOWMAXIMIZED)

I get error:
error XS0144: Cannot create an instance of the abstract class or interface 'ReportPro2.RpReport'
error XS1061: 'ReportPro2.RpReport' does not contain a definition for 'IsValid' and no accessible extension method 'IsValid' accepting a first argument of type 'ReportPro2.RpReport' could be found (are you missing a using directive or an assembly reference?)
error XS1061: 'ReportPro2.RpReport' does not contain a definition for 'PrintPreview' and no accessible extension method 'PrintPreview' accepting a first argument of type 'ReportPro2.RpReport' could be found (are you missing a using directive or an assembly reference?)

does anybody know what problem is.

Hi!
I think you need:
RpReportRDD instead of RpReport.
My call is like
oReport :=RpReportRDD{ SELF, cReport +".rpt", "D:MiscTuKVN_VersionDATAChris", Null_Array}

Yes, you are right.
But, now there is another error:

Hi Zeljko,

I think you have an old version of ReportPro, current versions have been refactored and allow you to use the class RpReport directly. Is it an X# or the old vlcan version of RP2 that you are using?

[vzeljko]

ReportPro 2 for XSharp 2.35.0.4
date: 26.11.2019

Hi Zeljko,

I can't see your email address, can you please send me an email at chris@ xsharp (dot) eu, so I will send you an updated RP version?

[vzeljko]

Problem is solved, thanks to Chris.
Because I call ReportPro from winform not VO window, I had to put this code

LOCAL oOwner AS USUAL

oOwner := __ForeignWindow{SELF:Handle}

and change this code:
oReport := RpReport{oOwner, cRptPath + cRpt, cDBFPath}

Chris, thanks again.

Glad it works for you now Zeljko and thanks for posting the solution here! Have to say I took that tip from Robert though
