En este momento me surge la necesidad de actualizar o mejor dicho cambiar el recorset en tiempo de ejecución, lo estoy intentando de la siguiente manera, pero al hacer el requery, sale un error.
Cabe aclarar que la primera vez, se muestra bien, el problema surge cuando hago click sobre uno de los botones.
- Code: Select all Expand view
#include "fivewin.ch"
#include "ado.ch"
function Main()
local oCnFtr, oRsFtr, oDlg, oBrw,cCnd,cQry,oError
local aSql := { "select * from tbl_empr", ;
"select * from tbl_empr WHERE e_codi='01'", ;
"select * from tbl_empr WHERE e_tipo='CONTABLE'" }
//CREAMOS UNA CONEXION PARA SOLO FACTURACION
cCnd := "DSN=dlyma;Uid=root;Pwd=secret;"
oCnFtr := FW_OpenAdoConnection( cCnd )
cQry := "USE dlyma"
TRY
oCnFtr:Execute(cQry)
CATCH oError
FW_ShowAdoError(oCnFtr)
END
oRsFtr := FW_OPENRECORDSET(oCnFtr,aSql[1],adLockOptimistic,adOpenKeyset)
DEFINE DIALOG oDlg SIZE 600,400 PIXEL TRUEPIXEL ;
