Store Password, Even The Developer Can't See It?
Jul 8, 2009
I went for an interview last week, and the interviewer asked me a question that i failed to answer.
He asked me, how did i store the password in the database. Then i answered that i would encrypt it then store it in database.
Then he said after encryption, developer or admin still able to view the encrypted password. But he didn't want developer or admin to be able to view the encrypted password.
I thought of cookies, but if user clear their cookies file, everything will be gone.

In CRUD application development we have to face the issues with concurencies in Ids such as Generate and display UNique EmployeeIDs on forms. Currently i'm writting .DLL file that has a class that will handle concurrencies.
But i'm puzziled with the Question, is this concurrency handle is part of the software developer or Database developer?

I need to be able to accept a password from a user in a WPF app, encrypt it then store this in a database and be able to decrypt later on. However I'm not sure how to implement this.
This is completely trivial so whether it's safe or not doesn't matter. All I need is for it to get working only I'm unsure exactly how to do it. I've tried playing around with the DESCryptoServiceProvider() but haven't gotten anywhere.
To be clear, how exactly do I go about converting a simple password into something that's been encrypted and storing it in the database (and what fields would I store it in). At this point, I'm happy if there's only one key and that key is being defined in the source code.

I have the following code which extracts the contactcode from a table in a database;
[Code]...
Code: lblUniqueID.Value() = (RandomPassword.Generate(4, 6)) Now, I want to compare the contactcode values extracted from the database and the value stored in lblUniqueID.Value(). If the random password is similar to one of the contactcode then generate another RandomPassword IF NOT then place the value to another label called lbltransfer.text.
I'll insert that value to the database.. The idea is extract all the contactcodes(these are the random passwords already generated and stored) from the database. Compare with the new generated password if it exists then create another one if not then store it in a label called lbltransfer.text.

I'm a newbie in visual basic. I'm doing a login system. I'm done with the GUI. but for the programming part, I want to know where to store new user's information along with the username and password. I've done research. seems like it has something to do with database. p/s: I'm looking for high security in storing data to prevent hacking.

I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --
Public Class Form1
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.Close()
End Sub

I'm a C# programmer who needs to pick up some VB. The syntax differences are easy enough to figure out, but there are other things I'll need more of a tutorial on. For example, VB's "strict" mode in Visual Studio is something essential to me, but something I wouldn't have learned just by comparing language syntax. Any recommendations on how to pick up VB quickly, yet thoroughly? I can't stand to work through a 1000 page book introducing VB to novices.

I'm trying to create a password change form for my company's vendors. There are a couple of scenarios I could encounter doing this:
1 - User enters invalid current password
2 - New passwords do not match
3 - User's account is locked
4 - User cannot authenticate because password is expired
It's case 4 that I'm struggling with, because their is no way for me to take the password the user entered and verify it against active directory without getting an error.

I am implementing a system where the user can Reset their password if they have forgotten it.Once it is reset I want to give them the option of changing the password so that it will be something more memorable to them.The password is hashed and if i enter in the correct old password and new password the password does change.If I enter in the wrong old password and new password the password doesnt change.Is there a way to match the old password with the old password field in code behind so I can throw up an error to the user to tell them what is wrong?

How do you get a textbox being using for password entry to display the black circle that you often see in web forms, on the iphone etc etc?
I can change the PasswordChar property to an asterisk no problem and even copying and pasting symbols inserted into Word seemed to work - just couldn't find a symbol that looked like a bullet point!
Can this actually be achieved for a standalone exe, or is it something unique to web forms? Surely copying and pasting symbols from Word isn't actually the answer?

I updated a VB.NET application from Visual Studio 2008 to Visual Studio 2010 and made a few changes to it. Now it works fine on my development workstation but when the user tries to run it, it fails. The error detail is below. I've searched for System.InvalidOperationException and found several suggestions but none of them have helped. There isn't any static initialization code in the application. I changed the compilation to x86 instead of AnyCpu. None of these has helped. The project is compiled for .NET 3.5 and that hasn't changed. Both environments are Windows 7 64-bit.
Does anyone have a suggestion as to how I might determine what is causing this?

I have been trying to download the Visual Basic and it took me 3 days now to download because my network is not always good, so when the net is off, I have to start it over and over again. My question is: How can I download the Visual Basic just once and for all so that I start learning how to build my first Windows Applications?

I've been an ASP.NET VB.NET Web Developer for the past 4 years, but its been mainly self-taught so I think theres a fair few basics I have probably not learnt along the way.I'm interested in switching to C#, and was wondering what book would be best to buy to learn this.Is Jon Skeet's 'C# in depth' book a good place to start learning, or would this be too difficult for me to start with?

Google search does not help. What is really funny about this is that from my search I see there are multiple solutions for this problem that have worked for different people, none of which apply to my situation.Why do I get the feeling that God does not want me to learn VB programming? (Grin)

I have completed a small VB console app to read data from a BT card scanner. From within the VS2010 developer the app runs as desired, capturing the data and displaying it on screen with console.writeline().When I compile and execute the code either from the debug bin version or the release bin version, the app only captures the first few bytes then closes. All the code is within the Module1 Sub Main. Is there a compile setting or other property that I need to adjust?

My home page contains three Dropdownlist controls, the lists are populated from my database i created ie. (From three tables)- Courses, Grades and Schools.
I want a situation whereby a user clicks on any of the Courses, or the Grades, or any of the Schools from my dropdownlist controls, and selects the search button, the names of the students that took the course, their grades in that course, and their schools should appear in a table form. if its a Grade that is selected, the names of the students with the grade, their courses and their schools should also appear in a table form. And likewise the School.

I have class containing 10 properties. It has constructor which accepts one string parameter say "Param1". This is actually a liabrary which will be exposed to the developer.
Now when developer writes a code for creating instance of this class and pass the param1, then depending on the value of param1 developer should be able to see limited properties.
If Param1 has value1 then developer should be able to see 4 properties.
if Param1 has value2 then developer should be able to see another 3 properties etc.

I am wondering how I would get the information on what errors get processed by the application.unhandledexception. I already handle the event and gather the information, but I am unsure how or what the best way to get that information to me (the developer).
So far I have vdialog that asks the user if he/she wants to send the error to me, kind of like when an error occurs in Windows XP and a dialog asks the user if they would like to send information about the error to microsoft. I am unsure what to do when the user clicks "Send".
I have thought about emailing to me, but I don't really want to put my email address as the from, because I might change it or its password in the future, thus breaking its usability.
I cannot yet do an anonymous FTP upload, because my website only allows one FTP user, and that is used only to update the website.
I also have thought about using the user's default email program, but that will not work in most cases of people who rely on web mail.
