Using Adodb.Command.Execute Method in C# and ASp.net

Can anyone please help me figure out what each of the parameters in this function mean

ADODB.Recordset_Command.Execute(out Object RecordsAffected, ref objParameters ,int options)

I am trying to query an Active Directory using c# in asp.net

After connecting to the active directory. I am unable to execute this command which retreives the data from
the active directory. Execute method is supposed to return a record set, But i am unable to figure out the
parameters of Execute method

Code:
ADODB.Connection Conn=new ADODB.Connection();
ADODB.Recordset rs=new ADODB.RecordsetClass();
Conn.Provider="ADsDSOObject";
ADODB.Command cmd=new ADODB.Command();
Conn.Open("Active Directory Provider",null,null,0);
cmd.ActiveConnection=Conn;
i have also specified the command text.
rs=cmd.Execute(?,?,?)

Can any one help me with this

Thank you

Try to use this code to execute your command !

object dummy = Type.Missing;
ADODB.Recordset rs = cmd.Execute(out dummy, ref dummy, 0);

OML is everywhere !

ADODB.Recordset objRS = null;
try
{
ADODB.Connection objConn = new ADODB.Connection();

int intConnectionMode = (int)ConnectModeEnum.adModeUnknown;
objConn.Open("Provider='SQLOLEDB';Data Source='MyServer'; Initial Catalog='MyDataBase';", UserName, Password, intConnectionMode);
objConn.CursorLocation = ADODB.CursorLocationEnum.adUseClient;
object objRecAff;
ADODB.Command cmd = new ADODB.Command();
cmd.CommandType = ADODB.CommandTypeEnum.adCmdStoredProc;
cmd.ActiveConnection = objConn;
cmd.CommandTimeout = 600;
cmd.CommandText = "MyStoredProcName";
cmd.Parameters.Refresh();
cmd.Parameters["@employeeID"].Value = 68;
cmd.Parameters["@startDate"].Value = "1/1/2008";
cmd.Parameters["@DaysToGet"].Value = 30;
object objParameters = cmd.Parameters;
objRS = (ADODB.Recordset)cmd.Execute(out objRecAff, ref objParameters, (int)ADODB.CommandTypeEnum.adCmdStoredProc);
}
catch (Exception e)
{
Console.WriteLine(e.Message);
}

return objRS;
}
