creating a password generator in VB using VS 2008.What I want to do is have a front end which has a text box (to enter password length), a button (to generate a password) and a label (to display the password).I have been successful in creating random numbers; however a password containing just numbers isn't sufficient. So I would like random characters including uppercase and lowercase letters.
View 4 Repliesi would like to create a password generator however i have a 2 text box aplication the top one is where the person types their e-mail address then select generate. the program must then use that address to generate a unique password only for that person if another email address is inserted in the top text box a total different password should be generated.
View 5 RepliesI am trying to do a somewhat different pw generator. The user can specify the amount of characters the password will be and whether to randomize between the alphabets A-Z, numbers 1-10, and maybe a hand full of symbols or so, and a combination of all three options. Also the user can use the "re-generate" button if he/she does not like the current password. I'm fairly new to VB, and would just like a push in the right direction to get started.

View 2 RepliesI'm the head of my companies IT Engineering Security Department. We handle all the user account creations, access rights, file shares, terminations, badges...etc. To make the task of user accounts creation easier, I am looking to create a Password Generator that runs off of "Word Banks" if you will.Right now I have 4 ComboBoxes with a list of words in each. I want to make it so that when I click "Button1" it will Randomly populate each ComboBox with a word from their respective lists and then all compile, in order, in a TextBox at the bottom of the App so we can copy it out to use for our respective account creations.
Example:I know nothing about VB's randomization functions, so I don't even know where to begin.I'm using VB Express 2008, but can use 2010 if needed.
So I've been wanting to make a random password generator for a while now and I was looking around on here for the code to do so. I came across this:
Dim random As New Random
Dim password As New System.Text.StringBuilder
For i As Int32 = 0 To 9
[Code]...
And I used it successfully. The only thing is I want to change it slightly. I want to change it to where, only a few are letters, and the rest are numbers. But for them to be combined. One example could be "DM23TH91PB". How would I go about changing this to do that?
I wanted to make a simple program for people to create passwords out of phrases. A phrase can be a quote, or something that is easy for you to remember. An example would be: "I visit the MSDN often". The passphrase from that would be: "IvtMo".Notice the case is retained. The phrase is just the first character of every word. The button click function is to convert the phrase into passphrase.The capital() function is change random characters in the passphrase to uppercase. This works by using the Dim x As
String = Int(TextBox2.Text.Length * Rnd())
which allows "x" to be equal to the length of the passphrase text times a random.
Controls: Button named Button1 CheckBox named CheckBox1 TextBox named TextBox1 TextBox named TextBox2
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
If TextBox1.Text <> String.Empty Then[code].....
i have a password generator and am trying to improve it by adding checkboxes for the diffrent character types eg ABC, abc, 123 , @~}
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[code].....
VS 2008 Creating a Password Application with Do Loop
View 4 RepliesI've been trying to work on a personal project, in which the user enters in a text string in the first text box, and when the user clicks the "encrypt" button, the SHA1 hash of the text appears in the next text box. I've googled around for some information on this, and haven't found much for Windows Forms and SHA1, only MD5. I've checked a lot of things on MSDN but to no avail.
View 1 RepliesI've read numerous posts and threads about random number generation, but I havent' run across this.If I generate a bunch of random numbers, the results are radically different if I create a new Random generator for each number than if I use on Random generator for all the numbers. The results are much more consistent and evenly distributed if I use the same Random generator.I would have thought the opposite,because creating a new Random generator each time should reduce the number of random repetitions, if a different time slice is used to create the random number.[code]......
View 9 RepliesI am creating a password managment tool and for the storage I will be using a text file, I want to encrypt so I decided I will use the Rijndael cypher. I have found source code which does this to a file:
http:www.codeproje...ncryptFile.aspx. It is well explained but I am but still struggling to understand parts as I never looked at cryptography at all before.
Private Function CreateKey(ByVal strPassword As String) As Byte()
'Convert strPassword to an array and store in chrData.
Dim chrData() As Char = strPassword.ToCharArray
'Use intLength to get strPassword size.
[Code]...
This assigns all of bytekey with half of the hash from byteresult. Am I correct? If not why not just use SHA256 instead of SHA512 as you are only using half of the hash. If somebody could explain this to me this would be great. Already confused and this is just creating the key, then the IV needs to be created(not sure what an Initialization vector does) then the encrypt/decrypt function. I think I will struggle understanding this but I am going to try.

View 4 RepliesI made an application that manages someones pets. It's fairly simple, a grid showing all pets and their properties, to which the user can add new pets, edit existing pets and remove pets. Properties of the pets include name, color type, birth date and more importantly the animals father and mother (not sure if that are the right terms for animals, but meh). The father/mother must be chosen from the same database and their IDs are stored as FATHER_ID and MOTHER_ID in the current animal, so only existing pets (eg, pets added to the database) can be chosen as father/mother.
Now, the application needs to be able to show a pedigree of each pet. It should show the details of the current pet, preferably with a picture, followed by its father and mother, and their details. The same is done for both father and mother, and for them, etc, etc, until its has covered a few (4 or 5) generations.
I realize this may be a little hard to understand, so here's an "artist rendition" of what it should look like: As you can see it should display the name of each family member and some of its details. As you go up in the tree (to the right actually) the room gets smaller so less details are shown, until only the name remains. Obviously the blank areas should be filled with similar information, but I was lazy and paint wasn't really cooperating.
I wanted to know how to make a 13-digit number with -'s from the press of a button.
View 4 Replies1. Is it possible to have vb.net piece together a legitimate word of a specified length, or do I need to have a massive word list, and generate a random number to pick a word from this list?
2. I also need to separate each letter of the word and display an image for each letter, and each letter going to the next based on a timer, and can also repeat on a button click.
Eg: TWO would end up displaying T W O, a few seconds apart from each other.

I am trying to build my own website and realized that it would be a big help to also create my own vb program to enable me to embed tags with simple clicks of buttons. I am having trouble getting my vb code to be compatible with html code (I keep getting vb syntax errors).
Here is what I've tried:

I am currently creating a tool that can manage local user accounts on Windows-PCs. I am using the functions described on
this MSDN page ; and after some struggling, I got most of them to work.
Unluckily, I haven't found a way to set the option "User must change password at next logon" while creating a new user account. I use the
NetUserAdd -Function to create the new user. I set the level to 1 and supply a
USER_INFO_1 -Structure . This structure accepts flags, and the flag UF_PASSWORD_EXPIRED seems to be exactly what I want - but when I set it, the user can log on without changing the password first...
I'm developing on Windows 7 Ultimate 64-Bit using Visual Studio 2010 Express.
Here's my code:
#Region "Constants"
Public Const UF_PASSWORD_EXPIRED As Integer = &H800000
Public Const USER_PRIV_USER As Integer = 1

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?

View 1 RepliesHow 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?
