RDS Questions...

Hi,

I want to use RDS for my applications to provide data access to remote SQL

Server 2000 database. Everything works just fine, but I have encountered
some 
problems that I cannot resolve:

So I have stored procedure that looks like this:
CREATE     PROCEDURE TestInputOutput
	@[EMAIL PROTECTED]
 int out,
	@[EMAIL PROTECTED]
 int out,
	@[EMAIL PROTECTED]
 int
AS
	SELECT @[EMAIL PROTECTED]
 = 2
	SELECT @[EMAIL PROTECTED]
 = 3
	return

And a simple programm code written on C#:
                ADODB.Connection cn = new ADODB.ConnectionClass();
                cn.Open("Provider=MS Remote;Remote 
Server=http://server;Handler=MSDFMAP.Handler;Data
Source=MyPubsConn",
null, 
null, 0);
                //cn.Open("Provider=SQLOLEDB.1;Data Source=(local);Initial

Catalog=catalog;User ID=user;Password=password", null, null, 0);
                ADODB.Command com = new ADODB.CommandClass();
                com.CommandType = ADODB.CommandTypeEnum.adCmdText;
                com.CommandText = "exec TestInputOutput ? out, ? out, ?";
                com.ActiveConnection = cn;
                ADODB.Parameter par = new ADODB.ParameterClass();
                par = com.CreateParameter("@[EMAIL PROTECTED]
", 
ADODB.DataTypeEnum.adInteger, 
ADODB.ParameterDirectionEnum.adParamInputOutput, 4, 330);
                com.Parameters.Append(par);
                par = com.CreateParameter("@[EMAIL PROTECTED]
", 
ADODB.DataTypeEnum.adInteger, 
ADODB.ParameterDirectionEnum.adParamInputOutput, 4, 1);
                com.Parameters.Append(par);
                par = com.CreateParameter("@[EMAIL PROTECTED]
", 
ADODB.DataTypeEnum.adInteger, ADODB.ParameterDirectionEnum.adParamInput,
4, 
DBNull.Value);
                com.Parameters.Append(par);
                object recAffected = Type.Missing;
                object pars = new object[3] { 330, 1, 1 };
                com.Execute(out recAffected, ref recAffected, 0);
                cn.Close();

1. When I try to use InputOutput or Output Parameter when executing stored

procedure - MS REMOTE returns me "an unexpected error". With Input
Parameters 
everything works OK and if I use that commented connection string it works

fine also. So, does RDS sup****ts Output Parameters?

2. if I supply DBNull.Value as a value of any parameter I get an error 
"Procedure 'TestInputOutput' expects parameter '@[EMAIL PROTECTED]
', which was not 
supplied." Of course with native SQLOLEDB Provider everything works fine.
I 
think that it must sup****t null values for the parameter. Of course I can 
avoid this problem by setting default values for parameters in stored 
procedure, but it's not what I want to do really.

3. this one is not critical, but MS REMOTE returns "an unexpected error"
if 
you try to set parameter's Attribute value to 
AdoEnums.ParameterAttributes.LONG for binary data parameter.

So I want to know can it be fixed, or may be I'm doing something wrong
with 
it.

I'm looking forward to hearing from you.
