Problem when print CODE128 using Barlib

Hi Guys,

I´m having a problem when try to print barcode using Barlib.

IF I print the string 15140803532877000111550020000018651000018657 using the pattern CODE128 and after I try to read the barcode generated, the value returned is different.

Do you know why ?

Try this fixed code:

Code: Select all  Expand view
FUNCTION _CODE128( cCode, cMode )

    LOCAL aCode := {"212222",;
                    "222122",;
                    "222221",;
                    "121223",;

Hi Enrico,

Don't work yet :(
I made a little sample:
Code: Select all  Expand view
  PRINT oPrn NAME "Teste Barcode" PREVIEW
   oPrn:SetPortrait()

   PAGE
      aMargin:=oPrn:SizeInch2Pix(1,1)
    Code128(aMargin[2],aMargin[1],"15140803532877000111550020000018651000018657",oPrn,"C",0,.T.,0.029,1.20)

   ENDPAGE

   PrintEnd()
 


When I read the barcode that is printed, the number returned is 15140803531118000111550020000018651000018657
The part that is returning different is '1118' that is bold/red in the string.

Double check that you are using the new code, please. It works fine here now with your sample. Maybe you need this function:

Code: Select all  Expand view
FUNCTION ISNUMBER( cStr )

    LOCAL i

    FOR i = 1 TO LEN( cStr )
        IF !ISDIGIT( SUBSTR( cStr, i, 1 ) ) THEN RETURN .F.
    NEXT

    RETURN .T.

Enrico,

You are right. I was doing "IsNumber" by a wrong way. Everything is fine now.
Thank you very much ;)

Hi Vilian
Can you send me the complete program to print code 128 starting from any number or name
Do you use barlib.lib or barlib32.lib and barcode.ch
Where do you position the .lib and the .ch (in fwh or harbour map)
Thank you

Hello,
May I ask why you don't use FIVEWIN’s build in EASYREPORT?

You read what you print.

The built-in barcode functionality of EasyReport can also be used directly using Printer class with this code:
Code: Select all  Expand view
function printbarcode()

   local oPrn, oBarcode
   local cText := "FiveTechSoft"

   cText := "15140803532877000111550020000018651000018657"

   PRINT oPrn PREVIEW
   oPrn:SetLandScape()
   PAGE

      oBarCode := FWER_BarCode():New( oPrn:hDCOut, cText, 700,100, 3000, 400, 3 )
      WITH OBJECT oBarCode
         :nBCodeType    := 3  // CODE 128
         :nPinWidth     := 10
         :ShowBarCode()
      END

   ENDPAGE
   ENDPRINT

return nil
 

Using the same barcode class that FWH EasyReport uses.
This class is already available in FWH. You do not need any external library.

What is 9.0 version?

Did you try the above code?
If it works for you, then the Easy Report runtime is included in your version.

Where is this function located ? :

FWER_BarCode():New( oPrn:hDCOut, cText, 700,100, 3000, 400, 3 )
Looking for the options that exist for :

 :nBCodeType    := 3  // CODE 128
