Re: what method to use for pushing page updates to page/iframes?

If you want the page to refresh itself, a js timer is the only way to do that. If only part of the page refreshes, you can use AJAX to make requests for that data.

The only code that could do this, is URL rewriting. Look at HTTP handlers.

No, I can't. I know that ASP.NET as it's typically used, plainly can't change a URL. URL rewriting can, and I know where to look for that info in ASP.NET. That's why my reply was tentative. I've not done it, I just know enough about ASP.NET to know where I'd look, so I gave you some keywords to type into google. Good luck.

Hello sir,

On registering our details to a new website, we recieve a confirmation mail along with user name, and password. How is it possibile? How can i do so using c#?

Nothing special... just during registration enter all the info into table, and leave the active field of the database as false. Send a confirmation mail with one transaction id, which you hold to the database upto a certain time... When the user clicks on the link you have provided with the email, it opens up a new page for activation, you can get the transaction id through query string or else ask the user to enter....

If the user enters correct transaction id, you can update the active bit field in the database and make the user active....

Hello sir,
I have to encrypt my password.I used the following statement.

string pswd = FormsAuthentication.HashPasswordForStoringInConfigFile(txtPswd.Text, SHA1 );

Error message is "SHA1 is a type not a variable".
How can i do?

Re: SHA1

The second parameter is expecting a string not an enum.

Try this:

string pswd = FormsAuthentication.HashPasswordForStoringInConfigFile(txtPswd.Text, <code>"SHA1"</code> );

A hash is one way. It cannot be decrypted. However, you can just compare the newly generated hash with the one stored like below.

string storedpswd = ... // retrieve stored password from your storage location
string newpswd = FormsAuthentication.HashPasswordForStoringInConfigFile(txtPswd.Text, "SHA1" );
if (newpswd == storedpswd)
{
   // passwords match
}else
{
   // passwords do not match
}

Sir,
To encrypt and also decrypt what algorithm can be used

Re: SHA1

Kelly Herald4-Mar-09 8:19

You can use TripleDES, Rijndael, or any of the non-hashing algorithms located in the System.Security.Cryptography namespace. Below is a link to MSDN's library for the TripleDES class and it has a complete example of how to encrypt and decrypt data. The other algorithms can also be found in the MSDN library.

Is there any equivalent to this when a combo is data bound? I've been through this hundreds of times before, but I'm having a brain freeze moment.

You could use UNC and HTML like so.

e.g. <a href="file://///domain/site/images/scanned/1.jpg" target="_blank">Scanned Image</a>

GridView and SelectedIndexChanged

Hi!!

public void GridView2_SelectedIndexChanged(Object sender, EventArgs e)<br />
    {<br />
 <br />
        TextBox tb = GridView2.SelectedRow.FindControl("id0") as TextBox;<br />
        if (tb != null)<br />
 <br />
           TextBox1.Text = tb.Text;<br />
 <br />
        else<br />
             TextBox1.Text = "no data";<br />
   <br />
        //TextBox1.Text = GridView2.SelectedRow.Cells[1].Text; <br />
 <br />
    }

This code returns me always "no data" even if there is data in the GridView.
I do not see where is the error.

thanks

Try debugging, that helps.
I guess the .FindControl is not finding your "id0", and for a reason.
Imagine you're looking for something, but it's there in front of you, just locked in a box.
Your textbox is in a cell of your .SelectedRow, now I can only assume by your commented-out code it's the first cell.

so do:

TextBox tb = GridView2.SelectedRow.Cells[1].FindControl("id0") as TextBox;

and it should be fine.
