is there a way to safely keep the value of a password field during postbacks in ASP.NET?
I was thinking of the viewstate, but I don't want to print it clearly in the HTML code by setting the control value equals to the viewstate content at every postback.
how to show plain text in password field and then make it regular password field on focus
View 3 RepliesI 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.
byte[] bytes = new byte[uploader.UploadedFiles[0].InputStream.Length];
uploader.UploadedFiles[0].InputStream.Read(bytes, 0, bytes.Length);
var storedFile = new document();
string strFullPath = uploader.UploadedFiles[0].FileName;
string strFileName = Path.GetFileName(strFullPath);
storedFile.document_id = Guid.NewGuid();
storedFile.content_type = uploader.UploadedFiles[0].ContentType;
storedFile.original_name = strFileName;
storedFile.file_data = bytes;
storedFile.date_created = DateTime.Now;
db.documents.InsertOnSubmit(storedFile);
db.SubmitChanges();
If:
Reading from a stream in a single call to Read is very dangerous. You're assuming all the data will be made available immediately, which isn't always the case. You should always loop round, reading until there's no more data.
How should I change the above code to make it 'less dangerous'?
I have the following code to encode password feild but it gets error when password feild greater than ten characters.
private string base64Encode(string sData)
{
try

Will this cause any harm? Does it serve any purpose other than tell browsers you have .net installed?I like this article about changing the header to Pure Evil.[URL]

Create User
Form to Email
Summary of Fields
When the finish button is clicked on the third step I would like to Create the user and send the form. I have the logic for this written but the only problem I have is the when the next button is pressed on a wizard, a PostBack occurs and my password field:
<asp:TextBox ID="txtPassword" TextMode="Password" Width="70%" runat="server" />
Does not retain its value.

View 2 RepliesI have a web service asp.net project which has a global.asax with empty Application_Start and Application_End implementations.As far as I can understand, in this case it is of no use and could be removed (correct me if I'm wrong).Do I need to do anything other than delete global.asax and global.asax.cs (such as change something in web.config or in the project settings)?Just asking in order to not screw up some dependencies I'm not aware of...

View 2 RepliesI am looking to create a confirm password field using asp.net MVC2 that works on the client. All my other client validation is done with MicrosoftMvcValidation.js by just adding the Html.EnableClientValidation(); call.
Some of my considerations. Should the confirm password be part of the model object? Using that approach i have created server side validation by creating my own model binder.
In your forum when I registered, there was a textbox for passwod in the register form and as I was typing more words or numeric charecters then a field with witten good/ strong password along with more colored field shown.........

View 1 Replies I want to use a RangeValidator Control which will validate my Password field where i want to check that if user enters less than 6 characters passwrod then it will prompt an error .
I want to give minimum & maximun password size ie minimum 6 characters. It could be alphanumeric & combination of special characters.
Maximum size should be 15 characterss.Same any combination o Alpha numeric or special charactors.
I have done it through Custom Validator .But how can i do this with Range Validator control.
I'm trying to user ValidatorCalloutExtender on my login page but I'm having some trouble with it. I have two TextBoxes, two RequiredFieldValidators and two ValidatorCalloutExtenders. Here's my page's code:
[Code]....
So, my problem is quite simple, I guess. When the user press "ButtonLogin", the first ValidatorCallout is displayed requesting that the user enter his username. The validation text for the password field isn't displayed. If I enter the username and then try to post the form again, the validation text for the password isn't displayed at all. The text is displayed only after I click on TextBoxPassword. Is there any way to solve this? If I wasn't using ValidatorCalloutExtender, text for both validators would be displayed. So, I'm guessing that internally both validators actually trigger. The second isn't displayed because the first one is already been displayed. But even after entering text on the first textbox, the text doesn't come up. I believe it's still thinking that the first validator is been displayed.
Is there a way to assign a value to the password field in the CreateUserWizard Control programmatically when the page loads. I would like to assign this value using a random password function that returns the password string without converting it an editable template.
View 2 Repliesive a simple webform where a checkbox enable the send button, this check is used for disclaimer agreement and has autopostback set to true; when a user insert all the required data to register, including his password and the check is clicked the password fields are reset to null because of the postback, i need to leave the check at the bottom of my module and consecuently the users most likely select it as last control.

View 1 RepliesI'm working with dynamic fields in ASP.NET due to a very specifc and rigid end-user requirement that would take 2 hours just to explain. Suffice it to say, I can't make the requirement go away.
Anyway, I have a working solution in place; no problems with controls loading, rendering or maintaining their ViewState. This is what my OnLoad looks like:

I want to force user to type more than 6 characters in password field.we cannot usee range validator because password characters can be mix(i.e.Numeric or alphabates or special characters)
View 3 Repliesi have searched this forum about this pbm. But People posted about Dynamic Image Button .. In my case, this is a static design only. I have a login page with image button as the Login button. I set Panel's Default button to that image button. onclick event Sometime fires, sometime not firing when pressing enter on the password field..If this happens once, then even if i click on the Image button also, the event is not firing.. but the form is post acking....Strange! i have removed panel's default button and wrote this line instead on page_load..
[Code]....
Still, the same pbm persists. Even i click on the imagebutton without pressing enter key also, the same pbm comes sometimes...I couldnt trace why.

View 1 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'm having the problem of my password fields being cleared when a postback occurs on a dropdownlist selection change.
Is it a security threat to fix it with this...

= ((TextBox)sender).Text;
}
I have inherited a database that is throwing me for a loop. Each user in this database has a "Password" and a "HashedPassword". I changed my password to "Testing" and discovered that the database stores the password like the following:
Original: "Testing"
Password Field: 211216058087052117197079019018007020147229039085161161
Hashed Password: 16e118ce2fd9e0cebda251af3a24fd6c5b6578ab
I was able to reverse engineer it to discover that the "Hashed Password" is generated using SHA1 encryption. My problem is, I can't figure out what is used for just the "Password Field". Can anyone give me any ideas of how to determine how the "Password Field" is generated? Can anyone look at this and tell me?
