C# to ASP to ACCESS having Charest conversion difficulties

[Julia]

Hi,
I am still having Charest conversion
difficulties s when passing string from C# TO ASP and than to access using
ADO
I am using HttpWebRequest to POST some Multilanguage(H ebrew and English)
to an ASP page which in turn uses ADO to save them to an access data base
the access data base support(as I underatdn( UNICODE strings),I can insert
Hebrew string fro access IDE)
Here is the code which create the POST request

//Executing POST command

string strPost=string. Format(
"GUID={0}"+
"&UserPassword= {1}"+
"&Email1Address ={2}"+
"&Email2Address ={3}"+
"&Department={4 }"+
"&FirstName={5} ",
Guid,
UserPassword,
Email1Address,
Email2Address,
HttpUtility.Url Encode(Departme nt),
HttpUtility.Url Encode(FirstNam e))

HttpWebRequest objRequest = (HttpWebRequest )WebRequest.Cre ate(url);
objRequest.Meth od = "POST";
byte[] data = Encoding.UTF8.G etBytes(strPost );
objRequest.Cont entLength = data.Length;
objRequest.Cont entType = "applicatio n/x-www-form-urlencoded";
try
{

System.IO.Strea m stream=objReque st.GetRequestSt ream();
stream.Write(da ta,0,data.Lengt h);
stream.Close();
}
catch(Exception e)
{
Console.Write(e .Message);
return false;
}

HttpWebResponse objResponse = (HttpWebRespons e)objRequest.Ge tResponse();
using (StreamReader sr = new StreamReader(ob jResponse.GetRe sponseStream()) )
{
result = sr.ReadToEnd();
sr.Close();
}
return result.ToLower( ).IndexOf("true ")!=-1;
}

and here is the ASP code which save the data the the data base

///The ASP which process the request

<%@ Language=VBScri pt %>
<%Option explicit
Response.Buffer =TRUE%>
<object RUNAT="server" PROGID="ADODB.R ecordset" id="rs"></object>
<object RUNAT="server" PROGID="ADODB.C onnection" id="conn"></object>
<%
Response.AddHea der "pragma","n o-cache"
Response.AddHea der "cache-control","priva te"
Response.CacheC ontrol = "no-cache"

//Just create the SQL UPDATE query

SqlString="upda te Graduates set "
for each i in Request.Form
SqlString = SqlString & i & " = " & RemoveNullNumbe r(Request.Form( i),0) &
","
next
SqlString= mid(SqlString,1 ,len(SqlString)-1)
SqlString=SqlSt ring & " where [Password]= '" & Request.Form("G UID") & "'"
conn.Execute SqlString,rsAff ected
conn.Close
if rsAffected=0 then
Response.Write SqlString
else
Response.Write "True"
end if
Response.End
%>
When display the result in a web page i see gibberish for records which was
entered using the ASP page
and Hebrew for records which entered using access IDE

I tried several encoders with no luck.

Thanks in advance for any help
