Yes, email is fine, it's certainly your most secure option. How you generate it is up to you, you could send part of a GUID, or have a table full of words and pull three out at random, or whatever you like.

Do you mean that I should add a new column of type GUID in the users table...I think it is a great idea because the passwords I sent to them will differ from each other.
Thank you for these great ideas.

It is better to send email to that person.
Make forgotpassword link.
On this page give a textbox so that user enters his email address.
Send him his newly generated password by email.
Update his password in your DB table.
If any quieries then please ask me.

Yes.
You could use brute force to find a password that gives the same hash code, but there is no guarantee that it's the same as the original password.
TheEagle wrote: I think when the user forgot his password the web application should generate a password for him automatically and send it to his email so he can log again using his new password.
Yes, that is what you normally would do when the passwords are hashed.
TheEagle wrote: Could any one tell me how could I make the web application generate the password automatically?
Pick some characters by random from a string with suitable characters. I exclude characters like "Il10oO" when generating passwords.
TheEagle wrote: Is it safe to send it by email to the user?
No, it's not safe. The email is sent unencrypted over the net, and it travels through mail servers that might be possible to hack into.
It might be safe enough for your purposes, though.

Thing is, what's a more secure option ?

Do you mean each time picking characters by random from the same string?Doesn't this mean that some passwords will be the same?

So what ? Do you take steps to ensure that no two passwords are the same now ? How does it matter ? It's not like users enter a password alone, they need the username as well, right ?

You are right.So I don't need to add a cloumn just a new GUID or a string to pick characters from it by random.Thank you very much and all experts who helped me in this thread.

If you have a string with 30 characters and pick four characters for the password, there is a 0.00012% risk that two given passwords will be the same.
If you generate a large number of passwords, of course some will be the same, but that is not a problem. Do you have a ATM card with a four digit PIN code? Have you ever stopped to think that there are thousands of other people who have the exact same PIN code as you have?

The main trick is that if they are server controls, you need to store their client side Id with something like
var controlId = '<%=ServerControl.ClienID%>'
Then it's just a case of
var control = document.getElementByID(controlID);
if (control)
{
control.disabled = true;
}

A quick way of doing it that doesn't involve loads of enabling and disabling is to add a "veil" to the page, which is basically a transparent div (or opaque - looks kinda cool!), sized to the full screen, then when you show your popup, show the veil on z-index 99, so that it's in front of everything else (except the popup window obviously) - this then stops anything behind it recieving input.

Hi,
After binding your dropdownlist to the datasource you can explicitly insert a listitem to the dropdown list.
the following is the code.
dlst.Items.Insert( 0, "Select One" );
I hope this will help u.
Thanks and Regards,

Hi,
I u want to create a single header which spans for more than one columns then you can use the following approach.
After binding your gridview to the datasource you can set columnspan for the cells in the headerrow.
gv.HeaderRow.Cells[0].ColumnSpan = 2;
gv.HeaderRow.Cells[1].Visible = false;
I hope this will help u.
Thanks and Regards,
Chetan Ranpariya
