Dear all,

Im trying to write my first asp.net webservice in c#.
this webservie has a public methode that returns a streamreader.
When calling this methode from my client side:

testWebservice.Service1 serv = new WebApplication1.testWebservice.Service1();
     StreamReader r = serv.CheckAccount(TextBox1.Text, TextBox2.Text);

i get this error:
Error 1 Cannot implicitly convert type 'WebApplication1.testWebservice.StreamReader' to 'System.IO.StreamReader'

What is wrong here and how can i fix this?

thanks

Error message is clear enough. Even if you clear this error, StreamReader can't be serialized and you can't use it with web services.

Hi Navaneeth,

What should i have to use instead of StreamReader? i have to return a soap message to the client.

Thanks.

Hard to tell without knowing much about the problem you are trying to solve. What are you expecting by returning a StreamReader? Are you trying to send contents of a file?

No not the content of a file.
Im getting soap envelopes from the server back through my webservice and i have to send this xml to the client that uses my service.

StreamReader HttpSOAPRequest(String xmlfile, string proxy)
{
XmlDocument doc = new XmlDocument();
doc.Load(@"C:\Inetpub\wwwroot\ASP.NET\" +xmlfile);
HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://uddi.microsoft.com/inquire");
if (proxy != null) req.Proxy = new WebProxy(proxy,true);
req.Headers.Add("SOAPAction","\"\"");

req.ContentType = "text/xml;charset=\"utf-8\"";
req.Accept = "text/xml";
req.Method = "POST";
Stream stm = req.GetRequestStream();
doc.Save(stm);
stm.Close();
WebResponse resp = req.GetResponse();
stm = resp.GetResponseStream();
StreamReader r = new StreamReader(stm);
return r;
//Response.Write(r.ReadToEnd());
}

Check if Session is still alive

Well.. this is not the simplle check if Session == null.

In a global.asax file I log in a table the sessionID of a user. In the Session_End i add to that logline the date the session expired. well that works!

But if a user chooses to close the browser in stead of logging out of an application....The additional logline with date session expiration is not saved.
In an overview page I see that according to the database some sessions are days old while the session timeout is set for 2 hours.

When I retrieve the data from the database is it possible to check with the IIS server if the found SessionID in the database is still valid for IIS?

In Word you can only store 2 bytes. That is why I use Writer.

Obviously you can assume any session over two hours is not valid.

A common practice I've noticed for this situation is to use a bit of AJAX to capture the browser events, whether an actual close or just navigating away from your site, and update the database to logout the user.

No. You can't get this.

Two things you can try,

1 - Handle browsers close event using JS and do AJAX call to update the database. This method is less reliable as JS can be manipulated from client side.

2 - Write a DB job which executes on specific intervals, check the validity of records and updates the records that are inactive for long time. For this to work, you may need to keep the last request time as well.

The browser can only use fonts installed on the client machine anyway, so whether the server has the font installed or not is irrelevant. You should stick to fonts common to all operating systems to ensure consistency.
