Report Application using Interbase-- tutorial

rbuser

I am working through the "Building a Report Application using Interbase"
tutorial, and when I run the application I get the error

FolderPipeline: 'plFolder' could not be opened.

ppReportExplorer1.FolderPipeline = plFolder
All other components are set to specifics in the tutorial... any ideas?

Check the database connection- can you connect? Then trace through the
Database -> Table -> Datasource -> Pipeline connections to make sure they
are connected. Does the RB_Folder table exist in the database? Did the SQL
script to create the RB tables in Interbase run without errors?

yes. to get rid of the errors, i opened the folder and item tables before I
executed the report explorer, and I set the validateSettings property to
false. This seems to work, but I am still curious why the pipeline couldn't
be opened with the validateSettings property set to true.

ValidateSettings is used when you call ReportExplorer.Execute. Execute
returns false if the pipelines can't be opened and an error message is
built.

if not(ppReportExplorer1.Execute) then
begin
pnlStatusBar.Caption := 'Error: ' + ppReportExplorer1.ErrorMessage;
MessageBeep(0);
end
else
pnlStatusBar.Caption := 'Explorer Launch Successful.'
