Load report

rbuser

Hi,

Is it possible to open a report (print, preview) in an end user application
by code.

Example of my code :

if Preview then
myEndUserSolution.ppReportExplorer1.PrintPreview(ReportName,FolderId)
else
myEndUserSolution.ppReportExplorer1.Print(ReportName,FolderId);

but the report isn't print.

Thank's

I tested your issue on my machine using RBuilder 7.01 with Delphi 7 and
found no problem. I used the (RBuilder\Demos\3. EndUser\2. Custom Data

Views\) demo and created a radio button group with one option to print and
the other option to print preview. The code in the btnLaunchClick

event was changed to the following:

procedure TmyEndUserSolution.btnLaunchClick(Sender: TObject);
begin

{The 'Print Preview' radio button is checked}
if (rbPreview.Checked) then

myEndUserSolution.ppReportExplorer1.PrintPreview('Customer List', 1)

{The 'Print' radio button is checked}
else

myEndUserSolution.ppReportExplorer1.Print('Customer List', 1);

end;

This seemed to function correctly. If you still have problems, please
provide a more detailed way to reproduce this problem.

1. The first test would be to get it working within the same program as I
did in my example.

2. The standard way to control one application from another is via COM.
There are some books on using COM with Delphi that can help you with this.

When I launch my application from another,
I don't execute the ppReportExplorer.Execute and the ppReportExplorer.form
is nil.

How do I assigned the ppReportExplorer.Form?

thank's

Below is an article explaining how to load a report without showing the
Report Explorer form. You can then use Report.Print.

---------------------------------------------------------------
Tech Tip: How to Programmatically Load Reports that were Saved
using the Report Explorer
---------------------------------------------------------------

1. The ReportExplorer has a run-time interface you can use to load reports
using the ReportExplorer.LoadReport method. You can use this method without
actually 'showing' the report explorer form. (See the online help topic for
TppReportExplorer.)

2. If you want use Report.Template.LoadFromDatabase, RB will locate the
report stored in the database table based upon the NameField value only.
However, for the rb_item table you need Folder_Id, Name to locate a record
uniquely.

To override this default behavior, assign an event-handler to the
Report.Template.OnLocateRecord event.

example:

TmyForm = class(TForm)
private
function ReportLocateRecordEvent(Sender: TObject; const aReportName:
String): Boolean;

end;

procedure TmyForm.FormCreate(Sender, TObject);
begin
{assign the event handler}
FReport.Template.OnLocateRecord := ReportLocateRecordEvent;

end;


function TmyForm.ReportLocateRecordEvent(Sender: TObject; const aReportName:
String): Boolean;
begin
{add logic here to locate the record and return True if it is found}

Result := myLocateReportFunction(FFolderid, aReportname);

end;
