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?

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

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.

How can the exception generated due to Page validation be caught ?
I am having RequestValidation=True (which is default) on my page.
Now, if the user enters some HTML tags, an exception is generated ...
How can that error be caught in the page where it occurred, so that the user can be asked not to enter html tags .... there itself ....
Please help me here .... Smile | :)

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.

var question = (_2b || !(_2b));

I tried your solution but it does not work Frown | :(

I want to have: the value of a cell of selected line in a GridView.
I read that i can do that :TextBox1.Text = GridView2.SelectedRow.Cells[1].Text;
but it doesn't work.

Seriouly? Ok... here goes:

You could change the Text displayed on it
You could change its Width
You could change its Height
You could change its foreground or Background Color
You could change the Tooltip displayed when it is moused-over
You could use an ImageButton and supply an ImageUrl
You could use an ImageButton and supply an AlternateText

and probably a whole load more that i'll leave to your own investigation.

Use < instead of < and > instead of >. The < > get treated as tags.

What is the error you're getting ?

Hi,

I have a login page in my application. (I m using C#)
In that I have disabled Cut, Copy and Paste using Javascript. Its working fine.

But, still user can drag and drop any text in these textboxes.

How can I restrict the use from this?
I dont want to derive any class from Textbox control..

Please advice.

Hi,

I found the solution in javascript only.

It was same as restricting user from Cut, Copy and Paste.

Solution is : ondrop="return false"
