count unique group

yvesarchambault

Hi, on a report with group1, masterdata, footer1, how could I count the number of unique group1 ?

example :

Pierre
   1- 
   2- 
   3-
   4-
Yves
   1-
   2-
Sylvain
   1-

       Total number of group = 3

Thanks

My solution :

create the variable 'Membres' in the report then add

procedure GroupHeader1OnBeforePrint(Sender: TfrxComponent);
begin
  set('Membres', FloatToStr(<Line>));                                                       
end;

Then put the variable Membres in the ReportSummary.

Voila. I don't know if it is "?©l?©gant" but it works.
