Problem with DBGrid1 selection and frxReport1.Print.

oyci3c

Hello.
I'm a bit confused...
I have a typical procedure where:

for nJ := 0 to DBGrid1.SelectedRows.Count-1 Do Begin
      DBGrid1.DataSource.DataSet.GotoBookmark(pointer(DBGrid1.SelectedRows.Items[nJ]));

*Do some stuff to get data for a report*

      frxReport1.LoadFromFile('report.fr3');
      frxReport1.PrepareReport();
      frxReport1.PrintOptions.Printer := ComboBox1.Text;
      frxReport1.Print;

end;

Everything is fine untill I have more than one selection (for example 2-3 rows or whole grid).
In debug mode this loop runs once ok (SelectedRows.Count value is for example 3) and after going for another run it sets the Count value to 0 each time thus giving me Access Violation error.
It only happens on frxReport1.Print (same thing with frxReport1.Export(frxPDFExport1)).
If I remove anything related to printing or exporting loop runs fine till the end.

Funny thing is that I have old application in Delphi 2006 which runs fine and now this happened in Delphi 2010. Both are using FR 4.0.

Help

I see that after calling frxReport1.Print; for first time it closes all my datasets... even the one not related to report itself.
Never had such problem with fastreports before as I'm using same procedures:(
When I //frxReport1.Print; from the loop/code everything works smooth.
