I not understood how work fieldWBlock
before run ok and now not run

I wish print a field using fieldWBlock

Code: Select all  Expand view

#include "fivewin.ch"

REQUEST DBFCDX


Function test()
 local acampi :=   {"FIRST"   ,;
                      "LAST"    ,;
                      "STREET"  ,;
                      "CITY"    ,;
                      "STATE"   ,;
                      "ZIP"     ,;
                      "HIREDATE",;
                      "MARRIED" ,;
                      "AGE"     ,;
                      "SALARY"  ,;
                      "NOTES"    }

local nFor:=1// first
 local oPrn
local oFont
local oBold

 USE CUSTOMER NEW alias cust SHARED VIA "DBFCDX"


PRINT oPrn PREVIEW

   DEFINE FONT oFont NAME "TAHOMA" SIZE 0,-14 OF oPrn
   DEFINE FONT oBold NAME "VERDANA" SIZE 0,-25 BOLD OF oPrn

   PAGE

    @ 10, 10 PRINT TO oPrn TEXT bCampo( aCampi, nFor,1 ) ;
                SIZE 100, 100 CM ALIGN "T" FONT oFont

      ENDPAGE
       ENDPRINT

   RELEASE FONT oFont, oBold


return nil

function bCampo( aCampi, nFor,nArea )
   return (fieldWBlock(aCampi[nFor],nArea ))

 

I tried also with fieldWBlock( "FIRST",1 )

[ADutheil]

Try
eval(fieldWBlock(aCampi[nFor],nArea ))

[Silvio.Falconi]

perhaps fieldget(n)
but I need to have the naArea

nCampo:= 2
aFields := {"FIRST" ,;
"LAST" ,;
"STREET" ,;
"CITY" ,;
"STATE" ,;
"ZIP" ,;
"HIREDATE",;
"MARRIED" ,;
"AGE" ,;
"SALARY" ,;
"NOTES" }



this Run ok if I wish print a barcode

Code: Select all  Expand view

nCampo:= 2
FIELDWBLOCK( ncampo, SELECT( "CUST" ) )

sample :

@ nRiga, nColonna PRINT TO oPrn TEXT FIELDWBLOCK( ncampo, SELECT( "CUST" ) ) ;
AS BARCODE TYPE "EAN8" ;
SIZE nWid-nCo, nHei CM BARSIZE nWid


If I wish print a text run with

Code: Select all  Expand view

 FIELDWBLOCK( aFields[nCampo], SELECT( "CUST" ) )

sample :

@ nRiga, nColonna PRINT TO oPrn TEXT FIELDWBLOCK( aFields[ncampo], SELECT( "CUST" ) );
SIZE nWid, nHei CM ALIGN "T" FONT oFnt


it's very strange because I call allways the field number 2 ( Last)

[ADutheil]

FIELDWBLOCK("FName", 1) is the same as &( "{ |setVal| IF( setVal == NIL, 1->FName, 1->FName := setVal ) }" )

If you don't eval the block you'll not retrieve the content of the field.

@ nRiga, nColonna PRINT TO oPrn TEXT eval( FIELDWBLOCK( aFields[ncampo], SELECT( "CUST" ) ) );
SIZE nWid, nHei CM ALIGN "T" FONT oFnt

@ nRiga, nColonna PRINT TO oPrn TEXT eval( FIELDWBLOCK( aFields[ncampo], SELECT( "CUST" ) ) );

I tried with eval make error

I took your initial example and rewrote a little:

Code: Select all  Expand view

#include "fivewin.ch"

REQUEST DBFCDX


Function main()
 local acampi :=   {"FIRST"   ,;
                      "LAST"    ,;
                      "STREET"  ,;
                      "CITY"    ,;
                      "STATE"   ,;
                      "ZIP"     ,;
                      "HIREDATE",;
                      "MARRIED" ,;
                      "AGE"     ,;
                      "SALARY"  ,;
                      "NOTES"    }

local nFor:=2

USE CUSTOMER NEW alias cust SHARED VIA "DBFCDX"


alert(  bCampo( aCampi, nFor,1 ) )


return nil

function bCampo( aCampi, nFor,nArea )
   return eval((fieldWBlock(aCampi[nFor],nArea )))
 

I works OK for me. The alert box shows Simpson

[ADutheil]

This works perfectly for me.

Also for me !!
When I tried to Print a BARCODE it make error
IT's very STRANGE because Barcode want code as text

sample

Code: Select all  Expand view

nWid:=0.2
@ 10, 10 PRINT TO oPrn TEXT  bCampo( aCampi, nFor,1 );
AS BARCODE TYPE "EAN8" ;
SIZE 3.6, 0.8  CM BARSIZE nWid

[ADutheil]

My FWH version is old and I'm not aware of the AS BARCODE command so I can't help you further.

[Silvio.Falconi]

THERE IS SOMEONE CAN HELP ME PLS ?

[ADutheil]

As you want to print a barcode the function may be expecting a string of numbers not letters.
