terminate report from code

  this will depend upon where in code and for what reason you are trying to terminate the report.
  
  assuming you loaded and called the report in this manner
  frxreport1.loadfromfile('path&filename');
  frxreport1.showreport;// this forms output and displays preview
  the easiest is to include an frxdialog form in the report
  with 2 buttons (run, cancel) and set their modal result properties to suit.

  thank you gordon, but it still doesn't solve my problem. i try describe it in detail:
  
  i want to print labels using "onmanualbuild" event in report. each label has particular count to print, but some of them have set unlimited count (999999). so when the count is unlimited, i want to show dialog form to specify new count for current label to print, or cancel (terminate) whole report by user without showing preview form.
  
  sample of source code:
  
  procedure PageOnManualBuild(Sender: TfrxComponent);
  var
  I, Count: Integer;
  begin
  if Engine.FinalPass then
  begin
  MasterData.Dataset.First;
  while not MasterData.Dataset.Eof do
  begin
  Count := IIF(MasterData.DataSet.Value = NULL, 0, MasterData.DataSet.Value);
  if Count = 999999 then
  if UnlimitedFrm.ShowModal <> mrOk then
  Engine.StopReport; //here i want not only stop report, but terminate it without showing preview form...
  
  for I:= 1 to Count do
  Engine.ShowBand(MasterData);
  MasterData.Dataset.Next;
  end;
  end;
  end;

  sorry it is not clear to me
  i don't understand why you are insistent upon using the onmanual build
  and a two passreport.
  can you post a sample app in the binaries news group?

  hi gord, it doesn't matter if the report is double pass or not.
  
  i posted a sample source code to binaries news group with topic "for gordk - terminate report from code"...
  please have a look at it.
  
  thank you in advance

  Hi mike
  here is what i would change based on what you posted
  add a variable to the report's categorized variables named Cancelled
  DO NOT give it any value.
  change the report code
  begin
  //here i want to terminate whole report job...
  set('Cancelled',true); //add this line
  Report.Terminated := True;
  
  end;
  change your delphi code
  procedure TForm2.Button1Click(Sender: TObject);
  begin
  frxReport1.PrepareReport;
  if not frxreport1.variables= true then
  
  frxReport1.ShowPreparedReport;
  end;
  
  BTW delphi form onshow event is a better place than oncreate to create client data
  i would load report file in button click event and turn off store in dfm.

  thank you for your quick reply,
  i experimented with the code and i didn't figure out why you added a new variable "Canceled". is it possible to use native variable Terminated instead? See following code:
  
  procedure TForm2.Button1Click(Sender: TObject);
  begin
  frxReport1.PrepareReport;
  if not frxreport1.Terminated then
  frxReport1.ShowPreparedReport;
  end;
  
  i tried the code above and it really works. where is the bug you mentioned?
  
  thank you again
