i has been created one login.aspzx page and one master.aspx page
when i login ,i m directly redirect to master page.master page contain logout button(linkbutten).
when clicked on logout button,the page has redirect to login page.
My problem is that,in that (after i clicked the logout button)when i clicked the "Back" it will move to master page.
i want clear the session or history?????
login.aspx page :
protected void buttonLogin_Click(object sender, EventArgs e)
{
if (string.IsNullOrEmpty(TextBox1.Text))
{ //Focus box before showing a message
// textBoxUsername.Focus();
TextBox1.Focus();
//MessageBox.Show("Enter your username", this.Text, MessageBoxButtons.OK, MessageBoxIcon.Information);
Response.Write("<script> alert('Enter your username');</script>");
//Focus again afterwards, sometimes people double click message boxes and select another control accidentally
TextBox1.Focus();
// textBoxUsername.Focus();
return;
}
else if (string.IsNullOrEmpty(TextBox2.Text))
{
// textBoxPassword.Focus();
TextBox2.Focus();
// MessageBox.Show("Enter your password", this.Text, MessageBoxButtons.OK, MessageBoxIcon.Information);
Response.Write("<script> alert('Enter your password');</script>");
TextBox2.Focus();
// textBoxPassword.Focus();
return;
}
using (DataTable dt = LookupUser(TextBox1.Text))
{
if (dt.Rows.Count == 0)
{
TextBox1.Focus();
// MessageBox.Show("Invalid username.", this.Text, MessageBoxButtons.OK, MessageBoxIcon.Error);
Response.Write("<script> alert('Invalid username.');</script>");
TextBox1.Focus();
return;
}
else
{
//Always compare the resulting crypto string or hash value, never the decrypted value
//By doing that you never make a call to Decrypt() and the application is harder to
//reverse engineer. I included the Decrypt() method here for informational purposes
//only. I do not recommend shipping an assembly with Decrypt() methods.
string dbPassword = Convert.ToString(dt.Rows[0]["Password"])…
string appPassword = (TextBox2.Text);
//we store the password as encrypted in the DB
if (string.Compare(dbPassword, appPassword) == 0)
{
Session.Add("islogin", true);
Response.Redirect("Firstmain.aspx");
}
else
{
//You may want to use the same error message so they can't tell which field they got wrong
TextBox2.Focus();
// MessageBox.Show("Invalid Password", this.Text, MessageBoxButtons.OK, MessageBoxIcon.Information);
Response.Write("<script> alert('Invalid Password');</script>");
TextBox2.Focus();
return;
}
}
}
}
master page :
protected void Page_Load(object sender, EventArgs e)
{
lblTime.Text = DateTime.Now.ToLongDateString();
if ((Session["islogin"] == null) || (Session["islogin"] == ""))
{
Response.Redirect("frmLogin.aspx");
}
}
protected void LinkButton1_Click(object sender, EventArgs e)
{
Session.Remove("islogin");
Session.Clear();
Response.Redirect("frmlogin.aspx");

If this is a paid job ( allowing you to set a time limit ), please place it in the job section.

It's clear you're barely learning how to use ASP.NET. You're clearing the session. The question becomes, how does each page make sure that the user is logged in, and redirect them if they are not ?

There's a lot of comments in this code that are wrong. Did you copy this code from somewhere ? In any case, I have to wonder why it is that you want help 'as soon as possible', but don't respond when someone answers.

Hi all,
In a ASP.NET website, I have used Login View to show the Login Status. For Login I have used Login Control.
It is showing status correctly. But after few idle minutes, it is automatically login view text changing to "login"
But user is already logged in. I think this is Session problem. I have used below line earlier. I commented it now.
Still same problem.
<sessionState mode="InProc" stateConnectionString="tcpip=127.0.0.1:42424" sqlConnectionString="data source=127.0.0.1;Trusted_Connection=yes" cookieless="UseCookies" timeout="1400" />
pl.help me out

Either the forum is by far the most complex part of your project, or you're in a real mess.

Hi
I am completely new to web services, but after doing some reading around, I have found that the WCF Web Services fits the bill. My project are looking to use the Web Service to get an XML document from a server and pass it through the same web service to another application and pass messages back in XML. The Web Service will not being doing anything except passing documents back and forth.
The Web Service will be called from an ASP.Net application.
Being completely new, is there an example I can follow that shows me how to pass an XML through a web service to an application and back again?
Thanks

Unfortunately both the links provided by you are not explaining what OP is asking.

You can read the XML file into a string and pass it like sending normal strings. After receiving the XML string, you can load it to XmlDocument class.

Hello friends,
Pls can you explain me difference between the document.write() and document.writeln() in JavaScript language?

writeln is almost similar to write, the only difference is writeln places a newline character after each expression.
Actually you cant see them in browser as newline character in browser is <br/>. But the html will be placed in newline.

means to say that if we use code something like
document.writeln("Hello");
document.write("Hello I am new here.");
then
OUTPUT:
Hello
Hello I am new here.

|

no .. as I already told you...
It places newline on the html not in its output.
Output will be
HelloHello I am new here.
but if you look into innerHTML it will write like
Hello
Hello I am new here.
To make the output appear newline, you need to use <br/>

I gave you the link to the documentation in my previous response. I would suggest you read through that a few times then create a test HTML file and see for yourself what the results are.

Hi...

why do you need to create Virtual Directory inside the Default Website?
Place the document in the Default web site and then configure it.

Yaa... thanks...I did the same and able to browse my website..its online now...
You can check it "x-student.com"...

yaa.. It happens sometimes. ... When you are in the beginning of your learning process we do mistakes .. but through this we all learn.. So dont worry about that...
Well virtual directory is just a directory inside the main web site. It is just given the flexibility to create multiple website inside the same web site and to use different application pool for the same web site.
Say you have
www.xyz.com
It might point to c:\xyzmain folder. The folder might contain a folder called c:\xyzmain\mno.. this is also a virtual directory. But the flexibility that IIS gives is to have a website running altogether in a virtual directory.
Means let www.xyz.com/mno points to C:\my documents\mywebsite.
This is the main advantage of Virtual directory. Although there are lots of more advantages.. .

Hi,
I have just downloaded the sql server 2008 version. I am currently developing a web application which is to be uploaded on the internet Now the web application and the database both will be uploaded on the same site .To be precise I am new sql server, whenever i try to run the website ,the login page comes perfectly but when I try to enter the id and password it shows me an error that :
Login failed for 'user\Guest'.
I think (but not sure) that this is sql server error and might be caused because of some roles or logins.
Can any one please help me with the problem that is am I correct , is there a way to resolve it
i am giving You the screenshot of the error here:
http://lh4.ggpht.com/_EC8qUhn9kJY/Sq4yFPLtvEI/AAAAAAAAAGA/Bt_L1eKpI7c/error.JPG[^]
I still dont know which will be the best forum to post this thread, so I am posting it here.
Any help shall be appreciated
thanks

you should give permission of ASP.net to the virtual directory. It shouldnt be login using user\guest, rather it should login using asp.net account.
