String Problem

rbuser

Hi,

while generating code128 Barcodes i found a bug in Reportbuilder 11.07:

If you use a string concatenation in the form

s:= CHR(208)+'Value';

inside a Reportbuilder event, the char-code 208 is APPENDED to the Value,
whereas

s:= CHR(208);
s:= s+'Value';

gives the correct value.

The following Procedure generates the Error "The barcode must begin with
#208 ..."

procedure BarCode1OnPrint;
var s:string;
begin
s:= CHR(208)+'F1000273';
BarCode1.Data := s;
end;

Hi Stefan,

In my testing with your exact code below, I was unable to recreate the issue
(with AutoEncode set to True or False). Which version of Delphi are you
using? Note that if you are using the AutoEncode feature, you should not
need to manually encode the barcode. This will be done automatically.

Hi Nico,

I use Delphi 7. Autoencode is Disabled.

It has nothing to do with the Barcode component.
Simply put a Label on a report with the following Reportbuilder-Procedure
(RAP):

procedure Label6OnPrint;
begin
Label6.caption:= CHR(65)+'Hallo';
end;

CHR(65) is 'A' - on the preview the label is printed as "HalloA"!

If i use
Label6.caption:= 'A'+'Hallo';
everything is ok - "AHallo" is printed.

For future reference, please either let us know you are using RAP before
asking a question, or post RAP questions in the RAP newsgroup.

There is now a patch available for RB 11.07 that solves this issue. Send an
email to support@digital-metaphors.com to receive the patch.
