I am trying to make a program in visual basic 2010 where the user enters hours minutes and seconds into text boxes and then the program will count down from that until its equal to 0 when a msgbox appears and says its finished. I was converting hour entered, minutes entered, and seconds entered all into seconds and then having a timer subtract 1 from that until its equal to 0. But the problem I'm having is that I want to display the hours, minutes and seconds left in a label to the user in a format of: "hours: 0 minutes: 23 seconds :42" but how to display it in this format.

I have already build a application where you type in your username and password and it changes it to the specified password. Now I want to make a "User password remover" application. (It should be the same as "Control PanelUser Accounts and Family SafetyUser
AccountsRemove Your Password").
The program should check:
1) Which User is currently logged on and using the program.
2) Check if the User has a password.
3) If No then Exit the program, else Step 4.
4) If YES then allow the User to type in his current password, press a button and Windows should remove the password.

I am making an application where a user can store their logons/passwords and other details for websites on the internet.My question is this: Am I able to have a list of all sites that the user has saved a password for on the internet?I don't think I will be able to get the password (because of Windows security), but am I able to see what sites the user has saved their password on, and maybe even the username they used?

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 have a project where I added visually and successfully a datasource of MySql. I binded a datagridview with a table.
But, how do I change programatically the password, ip or user to connect with the MySql server? Because it can change at any time, so I can let the user change these values.

I am currently making a boggle game, I have done finished every aspect of it expect the spell check bit. I have been searching the internet fruitlessly, and have only found spellcheckers but none of the results allow the program to know the word is wrong. So what I want my program to do is after the user has pressed done or the timer runs out, it checks the items in listbox1 and if it is wrong then puts the item in listbox2.

I don't like validating through the TextChanged event either as I believe that to be the cause of some issues. Doesn't the Textchanged event validate on each time a letter is typed?

I Create an application that when a user enters a positive integer value in a input box(the default number is 10) when the OK button is clicked, the application should display a message box with the sum of all the integers form 1 through the value entered by the user. If the user enters a negative value, the application should display an error message. I believe I have to use a loop condition but I have no idea what to do.
EX: User enters 10 in the input box once OK button is pressed a message box pops up and says "The sum of the numbers 1 through 10 is 55". Use the following test data to determine if the application is calculating properly
VALUE SUM
5 15
10 55
20 210
100 5050

Ok so I have designed a program to figure out commissions for phone sales at my company. Since the devices we sell and their associated prices change over time, I had to make that data within my program dynamic. I have a form within my program (frmprice) that has 160 textboxes - 80 for the devices and 80 for the associated prices. Now I hard coded the .text members with default values for our current stock of phones and prices.
I also added code so whenever that form with the phones and prices (frmprice) closes it saves any changes that have been made to either the phones or prices and when the form loads it overwrites the default data with any data that the user had entered at last run.
HERE is my logic problem. At the very first run the program is overwriting the default hard coded values with "" because no user data has ever been entered before. So when the form with the prices loads, it passes the user entered data from last run which is null because it has never run before. If I test to see if default value <> the user entered data before it executes the code to pass the user entered values it will always test to be true because the user entered data is null at first run. If I test to see if the default value is = to the user data it will always at first run test to be false because there is no user data yet.
HOWEVER once the user entered data is initialized (anytime after the first run) I need the program to pass the user data from the previous runs back in. Just NOT at the first run. Here is the code i am using: (in the code below the variables ending in "val" are the ones that are of the type string and are saved in the application settings) The frmprice_Load Event:

I created a usercontrol which has a Textbox and a Label. Setting the (boolean) textvalidity property we can toggle the icons on the label to show if the user has entered a valid input.
Sub New()
' This call is required by the Windows Form Designer.
InitializeComponent()

The problem is... when the control is used... the constructor initializes it to true (According to my code) so the icon is already displayed.

I've got a (hopefully) quick question. I've got textboxes attached to a binding source on one of my forms, and when I add, then clear, the data for the next entry to be added a small problem arises. If the user has previously entered something into, for example, Textbox3 and the user does not have the data for Textbox3 the user cannot move to the next field unless something is entered into the box.
