TStringlist and Tstrings

Hi!

I have just upgraded from Delphi5 and ReportBuilder 5 to
Delphi6 and ReportBuilder6

It seems to be some changes in RB6 that gives me problems.

Here is my working code for RB5:

SubReports := TStringlist.Create;
ppReportFromTreStruct.GetSubReports(SubReports);
MainChild := TppChildReport(SubReports.ObjectsSubReports.IndexOf('MainPage')]);

I get ListIndex Out Of bands when I run this.

In the help form GetSubReports :

Declaration

procedure GetSubReports(aReportList: TStrings);

Description

Returns a list of handles to all of the TppChildReport objects within a report in the Objects property of the TStrings. The Caption of the TppSubReport component is saved in the main property of the TString.

This Means that I should use TStrings instead of TstringList or?

OK I try to change to:

SubReports := TStrings.Create;
ppReportFromTreStruct.GetSubReports(SubReports);
MainChild := TppChildReport(SubReports.Objects[SubReports.IndexOf('MainPage')]);

Now I get som compiler warnings:
[Warning] Report.pas(708): Constructing instance of 'TStrings' containing abstract method 'TStrings.Clear'
[Warning] Report.pas(708): Constructing instance of 'TStrings' containing abstract method 'TStrings.Delete'
[Warning] Report.pas(708): Constructing instance
of 'TStrings' containing abstract method 'TStrings.Insert'

And the program crashes with Abstract Error on the row:

ppReportFromTreStruct.GetSubReports(SubReports);

Can someone help me out?

tstrings or tstringlist doesn't matter,

i guess the porblem is that

SubReports.IndexOf('MainPage')
in
MainChild := TppChildReport(SubReports.Objects[SubReports.IndexOf('MainPage')]);

returns -1

there is no entry 'MainPage'
and -1 is out of bounds of course

to get the correct naming (maybe all is uppercased now)
