.Net Oracle ORA-24338 'statement handle not executed' error and some error in one stored Procedure - asp.net

Question

I have the following Stored Procedures
create or replace PROCEDURE WEB_AC
(
v_iDocid IN NUMBER DEFAULT NULL ,
v_valor IN VARCHAR2 DEFAULT NULL ,
v_campo IN VARCHAR2 DEFAULT NULL ,
v_error OUT NUMBER
)
AS
v_campoid NUMBER(5,0);
v_tipodato VARCHAR2(50);
v_DOCTYPE NUMBER;
v_tabla VARCHAR2(50);
v_procedure VARCHAR2(70);
BEGIN
v_error:= 0;
IF v_valor IS NULL
OR v_valor IS NULL
OR LENGTH(TRIM(v_valor)) = 0 THEN
BEGIN
v_error:= 3;
END;
else
Begin
bEGIN
SELECT campoid,
doctype,
tipodato
INTO v_campoid,
v_DOCTYPE,
v_tipodato
FROM TiposDocumento t
, DIGITALIZAMAIN d
, CatCamposDocumento c
where
c.tabla=t.tabla and
nombre=v_campo and
doctype = TipoDocumentoID and
docid = v_iDocid AND
Mostrar = 1;
EXCEPTION
WHEN OTHERS THEN
v_campoid := 0;
END;
--select #campoid
IF v_campoid != 0 THEN
Begin
EXECUTE IMMEDIATE 'BEGIN ABANCE3.WEB_UPDOC' || TRIM(TO_CHAR(v_DOCTYPE )) || 'C' || TRIM(TO_CHAR(v_campoid)) ||'(' ||
TO_CHAR (v_iDocid)||' , '||CHR(39)||v_valor||CHR(39)||',:2);END;'
USING out v_error;
END;
END IF;
end;
end if;
END;
And
create or replace PROCEDURE WEB_UPDOC1C6(v_idreg NUMBER,v_valor VARCHAR2,v_temp OUT NUMBER)
AS
v_sys_error NUMBER := 0;
BEGIN
BEGIN
SELECT count(*)
INTO v_sys_error
FROM DOC1
where DOCID = v_idreg;
EXCEPTION WHEN OTHERS THEN v_sys_error:=0;
END;
IF v_sys_error > 0 THEN
BEGIN
BEGIN
UPDATE DOC1
SET DESCRIPCION = v_valor
WHERE DOCID = v_idreg;
EXCEPTION WHEN OTHERS THEN v_sys_error:=0;
END;
IF v_sys_error = 0 THEN v_temp:=0 ;
ELSE v_temp:=1 ;
END IF;
END;
END IF;
END;
and I'm calling them from an Application with this code:
Friend Function ActualizaCampos(ByVal iDocID As Long, ByVal valor As String, ByVal Campo As String, ByVal ProyectoID As Integer) As String
Dim mstrCS as String = "Here goes the connection String to my server"
Dim db As Database
Dim dbCW As DbCommand
Dim iValor As String = "0"
Select Case Me.TipoBD
Case GlobalDef.eTipoBD.Oracle
db = New OracleDatabase(mstrCS)
dbCW = db.GetStoredProcCommand(WEB_AC, iDocid, valor, Campo, 0)
db.ExecuteNonQuery(dbCW)
Case GlobalDef.eTipoBD.SQLServer
db = New SqlDatabase(mstrCS)
dbCW = db.GetStoredProcCommand(WEB_AC, iDocid, valor, Campo)
iValor = db.ExecuteScalar(dbCW).ToString()
End Select
Return iValor
End Function
In this example the WEB_AC SP always execute the sp WEB_UPDOC1C6
I have two problems with this.
First problem: At some point in the application I have the valor parameter (of the visual Basic Function) as a string with spaces that is something like "some string with spaces". When this happens, the stored procedure don't update the table. If I execute the SP directly in the DB (with SQL Developer) all works fine. I know it has something to do with the string missing some quotes(') but I haven't make it work yet. Some ideas on this?
Second problem: Sometimes, when debuging the application, if I interrupt the execution, I start getting the ORA-24338 'statement handle not executed' error for hours every time I try to execute it again. I believe it has something to do with an open transaction. But honestly, as I'm new in working with Oracle, I really have no idea what the problem could be.
Can you help me?
UPDATE: I have found the ORA-24338 real reason. It was another SP that was causing the error. When i found the solution to my other problem I'll post it all here.

I'd suggest that you replace your WHEN OTHERS clause with one that specifically names the erros that you are expecting, or you raise the error after handling it anyway. WHEN OTHERS is a bit contraversial as it is notorious for hiding the real problem.
