User Enters A Password - Must Be At Least 3 Characters Long - At Least 1 Number And 1 Alphabet Character
Mar 28, 2012
My homework assignment is to create a project where a user enters a password that must be at least 3 characters long with at least 1 number and 1 alphabet character. After that the password has to be encrypted so that vowels become X, numbers Z, and it reverses. For example, a password of CS2301 would be ZZZZSC. There's supposed to be Loops to extract 1 number/letter at a time and search for them in the string to validate, and I don't know what to do. The form itself has a Text Box to enter a password and a label to display the new one, and a Go button.
This is what my code looks like so far.
Option Strict On
Option Explicit On
Public Class Form1

I did this for one of my homework assignments in C#. However I need to do this in Visual Basic. For VB it just needs to be 6 characters and have one numeric digit and at least one alphabetic character.
Private Sub btnVerify_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnVerify.Click
public string getPassword()
End Sub
Private Function IsValid() As Boolean

I have a login form that I made. The user enters a username in textbox1 and then enters a password in textbox2. The user then hits the submit button (button2) and from there it works beautifully. The problem is, I would also like the user to be able to hit the "enter" key after they fill out the password textbox (textbox2) and have it be like they pressed the submit button. When the user hits enter right now, the form hides.

The latest assignment from my teacher was to create a console program where the user enters a character and the respective ASCII value in Denary, Hexadecimal and Binary, Even Parity, Odd Parity and Hamming code is returned.I've managed to implement all of them except the latter with relative ease, I am familiar with the concept of Hamming code and can compute it easily by hand, but don't really know how to implement it as a function in my program.

I am wanting to allow a user to enter a number and depending on what number is entered, it will allow that many entries. For example, if 5 is entered, the user has to enter 5 numbers. Those 5 numbers will then be added together.I 6 is entered, 6 total numbers will be added.I was trying to do this with a for next loop but I wasn't getting anywhere.

I just got started and here is what I have so far but when I run the program it is stuck in an infinite loop and will not go to the next function. I am not sure how to end the loop.
Here is what I have so far:
Module Module1
Dim SIZE As Integer = 5
Dim campus() As String = {"Decatur Day", "Decatur Evening", "Huntsville Day", "Huntsville

I 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.

Using visual basic, I have a string. Want to check that the string contains a single, capital alphabetic character followed by a period. Tried to use Contains as in the following:
someString.Contains("[A-Z].") but this didn't return me what I wanted.
Also need to check for a single number followed by a period.
How can I do this in Visual Basic

I'm making a custom control suited for handling passwords. I have created a control that inherits from a text box and I have implemented a lot of things so far. But what i want to do now is create a system so that when a user types It will display his last character typed for a X amount of time.Is there a way to turn only selected characters into password characters and still be able to get the password text from the Text property ?

For each character of this string I want a new character out of the string and then remove the character from the list of characters that still maybe used for other characters. It may not get the same character, you could basically just call this encryption, but it's not what I am making. I don't want to waste my time doing this one hour while VB can do this for me in <1 second.

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 was developing my own project in the university so what i am stack is to have save button which firstly validates what the user enters the form. for instance if the user skips the text fields, i wanted to restrict the user to fill all the form and when he completes, the save must be accomplished.
Here's the code i was trying to put but i was having problem saying the windows.forms.etc is unable to convert the save as Boolean and something like that.
Dim success As Boolean
Private Sub Save_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Save.Click
