Response Problem

Hi !
I am new to asp.net.
I m doing a project where in a mobile user is hitting my page for login authentication where in I accept the username & password, authenticate it , and send a response to him back.

When I use GET method it works fine but theres a problem in POST method
public void subResponse(string contents)
{
txtArr = System.Text.Encoding.Default.GetBytes(contents);
try
{
Response.Clear();
Response.OutputStream.Write(txtArr, 0, txtArr.Length);
objToErrorFile.writeResponse(contents, Server.MapPath(ConfigurationSettings.AppSettings["ErrorInfoDirectory"]));
Response.BinaryWrite(txtArr);
Response.End();
}
catch (Exception ex)
{
objToErrorFile.LogToErrorFile(ex.Message, ex.StackTrace, "Class: serverform Function/Sub: subResponse", Server.MapPath(ConfigurationSettings.AppSettings["ErrorInfoDirectory"]));
}

}

I used the above code
But the response he gets is as below :-

(J2ME response)
Running with storage root DefaultColorPhone
Running with locale: English_United States.1252
Running in the identified_third_party security domain
RMS Value : 0

Re: Response Problem

It also throws an exception called :-
"Unable to evaluate expression because the code is optimized or a native frame is on the top of the call stack"

Re: Response Problem

You rarely need to do anything with the output stream. Just add a label control and set the text property

public void subResponse(string contents)
{
label.text = content;
}

Are you trying to change the whole page? Most login pages simply redirect to the content page after authentication. Use server.transfer("contentpage.aspx").

Re: Response Problem

No,I'm not tring to change whole page or anything like that

I am jus sending a response in the form of 1 or 0 (i.e valid or invalid) to the j2me application.

Re: Response Problem

Well finally I am able to send correct reponse to the other j2me application but was not able to clear the exception that was mentioned above..

What is this exception all about..
