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 trying to store confidential encrypted user information for my program on a single computer. I do not want the application to be copied on to another computer and be usable. So I was thinking about storing the information in the Registry but I read that that is a very unsafe location and is bad for more reasons then one. I started storing the information in the programs Settings.config file but I am not sure how to encrypt that information. The only thing I have gotten to work so far is storing the information in a XML file and encrypting that which has worked but I want the information to be more hidden and more secured.

I need to have the ability to have a Global variable/class that stores some basic information about the currently logged in user including that user's preferences, security rights, UserID, etc. This information will be needed by any/every part of my application. In the past I have either used a Public variable/class in a vb.net module for this purpose. I'm trying to get away from my old ways of doing things and was curious what people currently do for this functionality.
I am thinking a singleton or 2 regarding preferences and security but am not sure if that is the best way to go.
EDIT: I asked this when I was too sleepy last night. This is an n-Tier WinForms application.

I need to store specific information about a user in a file of some sort. Something like an old ini file?
I will need to save a file for each customer.
CustomerName
OrderDate
DeliveryDate
[Code]....
All things point to a database but for several reasons I can't use a database.

I have an ASP.NET application. It resides within another ASP.NET application. I put my DLL in the other apps bin folder and have a subdirectory with my aspx files. I can't edit the main app's Web.config.
So where can I store configuration settings? For example, this is an app that will get deployed to various clients. I want to store the client name used for display in the headers and such. And the location of a logo file.

Basically i am creating a console application that will create and store client information as a .txt file it is going okay but i have come across a slight hick up i want to use something on the lines of this .....
dim lastname as string
Do Until Integer.TryParse(Console.ReadLine(), LastName) = False
Console.WriteLine("Invalid input, Please try again")
Console.Write("LastName:-")
[code].....
this works fine to trap out numbers from letters but the problem i am getting is when the program calls uppon LastName it is recording 0 and wanted to know if there is a way of getting past this ..... so basically i need a way to allow letter but not numbers and symbols and then dispay a pernolised error message but at the same time use Stream writer to save was the answer is in a .txt file.

Which is the best way to store application and user settings of an application running with multiple instances?My problem is that using the vb's "Application Settings" one instance would overwrite the other one.I want to identify each instance with a number passed via command line argument. I could use this number to identify the appropriate settings of the running instance, but I see in a local INI o XML file a better way to handle that.

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 want to store some information of the form in such a way that if the user quit/exit the application it stores the information. When user runs the application next time the information should be available to him. It also involve the restart of the computer. The application is in vb.net 3.5 framework. The one way that i can think of using flat files and encrypted data, but i can not do this. I do not to store any kind of data on client side and I can not store this information on server side. The problem is of getting client machine information and storing it on server.

I am creating a windows application using visual studio. I want somehow to insert an excel file into the application so the user will be able to download it from the program and save it to his computer. This means that the file will be a part of the program. There will be a button that will prompt the user to save the particular file somewhere so he can then view it.
What should I do in order to "embody" the excel file to the application? And what code should I write to link the file with the button?

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.

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 was wondering how you can copy information (from a webpage, for example) and store it in a string?Also, how would I take only one word of the string if there are spaces between words and I will always be removing the word with the same location in the string (for example, the last word in string).

I have a config file that I store information in and parse using streamreader. For example..
configfile.txt TEMPLATE NAME: mytemplatename TEMPLATEDIRECTORYPATH: C:TEMPWOOF.TXT
I had been doing a split function after the ":" but, that doesn't turn out so good once you add in file paths. I have turned to trying to grab the first ":" from the left using the "InStr" function which returns the char integer. I need a way to grab all the information on that line after the first ":".

I am new to development and I am looking for some pointers. I have a sql 2000 database and a vb.net app. Right now the SQL username and password to connect to the database is stored in the VB application which is not convenient since we must change the password periodically. The user opens the app and enters the username and password for the vb application. Using the credentials stored in the application to connect to the sql server, the app checks the username and password stored in a user table in the database to determine if they are allowed to connect or not. For various reasons, it is not feasible to simply have the application username and password be the same as the database username and password. We must have only one database username and password and it must be changeable. Like I said, it is now stored in the compiled application which is inconvenient.
