textbox1.attributes.add("value",passwordvalue);

Same happing with when i edit record. password doesn't show in textbox.
How can I use Membership.GeneratePassword to return a password that ONLY contains alpha or numeric characters? The default method will only guarantee a minimum and not a maximum number of non alphanumeric passwords.

And one more thing, i also want to save these textboxes' text in database table. how to do that. [ i am confused cos i dont know the no of textboxes will generate so how can i writeinsert query for that ]
I'm attempting to create a pure t-sql representation of the default SHA-1 password hashing in the ASP.Net Membership system. Ideally, what I would get would be this:
UserName Password GeneratedPassword
cbehrens 34098kw4D+FKJ== 34098kw4D+FKJ==
Note: that's bogus base-64 text there. I've got base64_encode and decode functions that round-trip correctly. Here's my attempt, which doesn't work: SELECT UserName, Password, dbo.base64_encode(HASHBYTES('SHA1', dbo.base64_decode(PasswordSalt) + 'test')) As TestPassword FROM aspnet_Users U JOIN aspnet_membership M ON U.UserID = M.UserID
I've tried a number of variations on the theme, to no avail. I need to do this in pure T-Sql; involving a console app or something like that will double the work. So if anyone can supply what precisely the syntax should be to duplicate that password from the ASP.Net membership stuff
I am looking to store a string field, a password, in a location that I can access within the code, but if you downloaded the code from a deployed place, you would not be able to access the password. Web.config is available for all to see, or else I would just slide it in there.

View 1 RepliesI just finished setting up the environment for an ASP based web app on a Windows Server 2003 machine, IIS 6.0, ASP.NET 4.0., with custom service account.This is not a domain based setup, so I have created mirrored logins on both servers (WEB server and SQL Server 2005). Everything works just fine except the fact that every time I try to browse the main page, a login pop-up window will request login password confirmation. I tried many things so far. Making sure IIS is in NTLM Authentication mode, checking access rights for the local login I created, workarounds I found on MSDN, etc.
This happens only if I change the Directory Security to not allow anonymous access (Authenticated Access - Integrated Windows authentication only). If I keep both, or only anonymous, everything works fine.Is this the intended behavior? Am I doing something wrong here?I already tried everything I found on MSDN regarding these types of errors. If I do not enter a password for three times in a row, the error says "HTTP Error 401.1 - Unauthorized - Access is denied due to invalid credential."
When a user that has their IE set to save passwords hits my "Reset Password" form, the first text box set with TextMode set to "Password" is populated with the users saved password. Understandable, this is not the affect I would like as this is their "old" password. I cannot set the text of a text box with mode set to "Password" (naturally). Does someone know how to suppress or clear this value when IE is saving passwords?
View 4 RepliesI can recover my password but when I try to change my password to something a bit easier to remember it gives me:
Password incorrect or New Password invalid. New Password length minimum: 7. Non-alphanumeric characters required: 1.
I am using the below post to encrypt and decrypt the password.
ENCRYPT POST
Now my code is working for Encryption. But now what I want is,
When I am using Forgot passwprd functionality, I want to send the decrypted password to the respective user in the Email.
In my database table the password is saved in the Encrypted format.
I have the code decrypt code from the above mentioned post, the question is where to place in the below code so that it will decrypt it properly

View 1 RepliesI have a web form, which is to allow user to reset their password. When I clicked on the button, I got this error
"Input string was not in a correct format."
The code behind the button is:

When the user types in the new password, this new password will be hashed upon clicking the button and saved into the database.
I have written a javascript code for handling the password functionality. The scenario is: when user wants to change the old password, he cannot fill the same old password again. I have written the code. But even the simple alert of blank textbox is not working. See the code for reference:
Javascript code:-
<script type="text/javascript">
function ltrim(str) {
var reg
reg = /^s+/g
return str.replace(reg, "")
}
function rtrim(str) {
[Code] .....
aspx code:-
<tr>
<td class="auto-style1">Old Password</td>
<td class="auto-style2">
<asp:TextBox ID="txtOldPassword" runat="server" TextMode="Password" class="txtcareer"></asp:TextBox>
<asp:RequiredFieldValidator ID="reqtxtOldPassword" ControlToValidate="txtOldPassword" runat="server" ErrorMessage="*"></asp:RequiredFieldValidator>

I have a form that is used to add and edit data. Based on a dropdown selection, the form is either prepopulated or left blank so you can add new data.
I have a password field that is set to TextMode="Password" and works fine when adding new data, it displays ***** as you type..
Now if you select from the dropdown and there is already a record on file, it populates the form to allow you to edit the information.. Now i DONT want to display the password in plain text, but i want to populate the field so if they make any changes all field data is kept and table is updated with all of it.
I already debugged the page and my variable is being set with the password, but the textbox doesnt even show the ***** for the password value.
