oRecordSet:Fields(1):value;
ON DBLCLICK (odlgbus:end(),wr:=.t.) ;
SIZE 258,68 OF oDlgbus PIXEL

olbx1:aheaders := ::titulos
olbx1:acolsizes := ::sizes
oLbx1:aJustify := ::just
olbx1:aHJustify := ::justh

oLbx1:bLogicLen = { || oRecordSet:RecordCount }
oLbx1:bGoTop = { || oRecordSet:MoveFirst() }
oLbx1:bGoBottom = { || oRecordSet:MoveLast() }
oLbx1:bSkip = { | nSkip | Skipper( oRecordSet, nSkip ) }
oLbx1:cAlias := "ARRAY"



Gracias desde ya

Te falta la funcion Skipper() que esta en el ::Bskip

este es el codigo:

STATIC FUNCTION SKIPPER( oRs, nSkip )

LOCAL nRec := oRs:AbsolutePosition

oRs:Move( nSkip )
IF oRs:EOF()
oRs:MoveLast()
endif
IF oRs:BOF()
oRs:MoveFirst()
ENDIF

RETURN oRs:AbsolutePosition - nRec

de hecho si compilo el codigo que tu me pasaste me da el mismo error

Cuando estas creando el Recordset, ¿ que tipo de cursor estas usando ?

¿ Puedes poner tu cadena de conexion y la creacoin del RecordSet ?

[alex_cyr]

ahi va:

oConexionAdo := TOLEAUTO():New("adodb.connection")
oComando := TOLEAUTO():New("adodb.command")
oConexionAdo:Open("Provider=Advantage.OLEDB.1;User ID=adssys;Data Source="+xrutab+"dd.add;Persist Security Info=False;ServerType="+xservidor+";LockMode=ADS_COMPATIBLE_LOCKING")
oComando:ActiveConnection(oConexionAdo)

cQuery := 'SELECT '+::campos+' FROM '+::base+' ORDER BY '+::orden
oComando:CommandText := cQuery

oRecordSet := oComando:Execute()


es todo:

No señor, te falta definir el tipo del cursor en el RecordSet, por eso no te puedes mover sobre el browse.

Necesitas hacer lo siguiente:

Code: Select all  Expand view

*---- CursorTypeEnum Values ----
#DEFINE adOpenForwardOnly 0
#DEFINE adOpenKeyset      1
#DEFINE adOpenDynamic     2
#DEFINE adOpenStatic      3

*---- LockTypeEnum Values ----
#DEFINE adLockReadOnly        1
#DEFINE adLockPessimistic     2
#DEFINE adLockOptimistic      3
#DEFINE adLockBatchOptimistic 4


oMiConexion := TOleAuto():New(“adodb.connection”)
oMiConexion:Open("Provider=Advantage.OLEDB.1;User ID=adssys;Data Source="+xrutab+"dd.add;Persist Security Info=False;ServerType="+xservidor+";LockMode=ADS_COMPATIBLE_LOCKING")

oRecordSet := TOleAuto():New(“adodb.recordset”)
oRecordSet:LockType := adLockOptimistic
oRecordSet:CursorType := adOpenKeySet
oRecordSet:ActiveConnection(oMiConexion)
oRecordSet:Source := 'SELECT '+::campos+' FROM '+::base+' ORDER BY '+::orden
oRecordSet:Open()

Es muy importante que el Tipo de cursor del recordset lo pongas como adOpenKeySet para que te puedas mover, de lo contrario solo puedes ir hacia adelante y no hacia atras.
