How can I use Combo Box to enter a value from a dbf field ?

Ehab:

Up to 256 elements:

Local aRubro:=CARGACOMBO( .f., "RUBRO",2,"NOMBRE" )

REDEFINE COMBOBOX oRubro VAR cRubro ITEMS aRubro ID 111 OF oFld:aDialogs[1]

Function CARGACOMBO(VACIO,XARCH, XORDEN, XCAMPO)

Local ORD_ACT, AREA_ACT := SELECT()
Local VECTOR:={}
DBSELECTAR(XARCH)
ORD_ACT = INDEXORD()
SET ORDER TO XORDEN
DBGOTOP()
IF VACIO
AADD(VECTOR,SPACE(LEN(EVAL(FIELDBLOCK(XCAMPO)))))
ENDIF
DO WHILE !(XARCH)->(EoF())
AADD(VECTOR,EVAL(FIELDBLOCK(XCAMPO)))
(XARCH)->(DbSkip())
ENDDO
SET ORDER TO ORD_ACT
SELECT(AREA_ACT)

RETURN VECTOR

You can use \source\classes\dbcombo.prg

To the first reply :
*------------------
I tried your help about combo Boxes but I got that error message :
Argument error : ALLTRIM()
I do not find any alltrim in the whole program .
To the second reply :
*------------------
I could not find any /source/classes directory in my evaluation version ,So I could not practise any dbcombo programs .

An old versión (ten years ago), but try this:


. . . . . .

@ nFile, nCol COMBOBOX oCbx VAR cCbx ;
ITEMS aBase ("client.dbf", 42, "fieldnom" )

. . . . . . . .

// -----------------------------------------------------------------------
// Function ..: aBase
// Descriptión: Create an array from dbf
// Parameter .: cFichero (dbf name)
// nAncho (array width)
// cCampo (field name)
// Return ..: acDevuelve -> array
// Manuel Valdenebro ... MALAGA/SPAIN
// -----------------------------------------------------------------------

FUNCTION aBase ( cFichero, nAncho, cCampo )
LOCAL acDevuelve := {}, nAreaActiva := Select()

aAdd( acDevuelve, space( nAncho ) ) // Put First element empty

SELE (cFichero)
dbGoTop()

WHILE !Eof()
aAdd( acDevuelve, (cFichero)->&cCampo )
dbSkip()
ENDDO

SELE ( nAreaActiva )

RETURN( acDevuelve )
