DELPHI quick report cahnge value at runtime 1

[kyriakos70]

Hi,
I have a question which is not derectly to Delphi, I have a quick report form in my application and want to change a value of a database field (qrdbtext) at run time or if not possible of a quick report label.

Thank you
Kyriakos

you say you want to change a value of a database field. that would mean the value comes from the database so you need to change it there, not in the report.

Yes, actually you can. Most QuickReport objects have an OnPrint event that look like this:

procedure TQReport.QRLabel20Print(sender: TObject; var Value: String);
begin
  Value:= MyData.FieldByName('MyField').AsInteger + 100
end;

In the example above, the "value" displayed will be 100 greater than the value in the DB.

OOPS: To funtion properly, it would need to be

procedure TQReport.QRLabel20Print(sender: TObject; var Value: String);
begin
  Value:= IntToStr(MyData.FieldByName('MyField').AsInteger + 100)
end;
