print a value from dbf (fieldWBlock)
Posted: Mon Nov 08, 2021 12:31 PM

I must return me the value of a field on a dbf

this is a small test

Code (fw): Select all Collapse

#include "FiveWin.ch"


REQUEST DBFCDX
     

Function test()
local odbf,cField,ctxt

     oDbf:=TDatabase():Open( , "Customer", "DBFCDX", .T. )
     oDbf:setorder(1)

     cField ="first" 
     cField:=trim(cField)           
     ctxt:=bCampo( cfield,oDbf)  //give me an array

?ctxt

return nil 

static function bCampo( cCampo,oDbf)
   return   oDbf:fieldWBlock(cCampo )

If I made

xbrowser ctxt

I see this

If I made

?ctxt[1] or ?ctxt[1][1]

make error why ?

How I can resolve ?

Dear Silvio,

function bCampo() is returning a codeblock and that is what you see (not an array)

Simply evaluate the codeblock providing the parameters
