Use of ReportPro 2 in a migrated VO application

[wriedmann]

Hi,
I have now tried to use ReportPro 2 in a migrated VO application, and have some problems.

In VO, the class RpReport can be simply instanciated - in the X# version no more because the class is defined as abstract. And there are missing some methods of the class RpReport, like SetVariableValue() and PrintPreview().

I have looked in the assembly ReportPro2.Runtime.dll.

What I'm missing here?

Thank you very much!

Hello,

I have found it now: the class to use is RpReportRDD or RpReportSQL.

Wolfgang,
That is right. There is also a 3rd class RpReportDesigner that needs to be used when you want to include the designer in your app.

Hi Robert,

thank you very much!
Do you need a list of overloaded methods that need to be changed so the rpReportRDD object can be used in existing VO applications?

Wolfgang,
Yes please.

Hi Robert,
the RpReportRDD class has currently the following parameter list:

Code: Select all

METHOD PrintPreview(cJobName AS STRING, cPrint2FileName AS STRING, cCaption AS STRING, cMessage AS STRING, lModal AS LOGIC, nShowState AS INT, nZoom AS DWORD, symPPWindow AS SYMBOL) AS VOID

AFAIK this list is not congruent with the VO version.
So at least the following overload is needed:

Code: Select all

METHOD PrintPreview(cJobName AS STRING, cPrint2FileName AS STRING, cCaption AS STRING, cMessage AS STRING, lModal AS LOGIC, nShowState AS INT) AS VOID

and maybe also this one:

Code: Select all

METHOD PrintPreview(cJobName AS STRING, cPrint2FileName AS STRING, cCaption AS STRING, cMessage AS STRING, lModal AS LOGIC, nShowState AS INT, nZoom AS DWORD) AS VOID

Wolfgang,
In the next build of RP2 I have added default values for most of these parameters

Code: Select all

    METHOD PrintPreview(cJobName := "" AS STRING, cPrint2FileName := "" AS STRING, cCaption := "" AS STRING, ;
cMessage := "" AS STRING, lModal := FALSE AS LOGIC, nShowState := SW_SHOWNORMAL AS INT, ;
nZoom := ZOOM_WHOLE_PAGE AS DWORD, symPPWindow := NULL_SYMBOL AS SYMBOL) AS VOID

That should help, I think.

Hi Robert,

thank you very much!

May I suggest another change: in VO, the report class is RpReport, and in X# the RpReport class is abstract.
I would rename the abstract class to RpReportBase (or any other name), and add three new assemblies that define stub classes called RpReport, inheriting from RpReportRDD, RpReportSQL and RpReportDesigner.
So for migrated applications everyone could decide which assembly to include, and no VO code needs to be changed.
For applications migrated from Vulcan there is no change needed.

Wolfgang,
I'll see what I can do.
