Is there a way to repeat two popup input boxes (in succession) until the user presses cancel?
Dim hours As Integer
Dim letterGrade As String
Do
hours = InputBox("Total credit hours", "Total credit hours", )
letterGrade = InputBox("Letter Grade", "Letter Grade", )
Loop
The input boxes continue to repeat but when I hit cancel nothing happens... I'm sure I'm missing something to tell it when I cancel to go back to the MainForm I just don't know what it is.....

How do I make it that the user must enter a number between 1 and 100? And If they dont they get an OK messagebox stating that they must do.I imagine it'll be something like this:
If TextBox1.Text = "" Then
MessageBox.Show("You must enter a value between 1 and 100", "Name Entry Error", _
MessageBoxButtons.OK, MessageBoxIcon.Exclamation)
End If
But Im not sure whats suppose to go inbetween the speech marks.

I am using VB .Net 2.0. I know I can detect the OS using
System.Environment.OSVersion
Can anyone tell me if there's a list somewhere where I can find what that generates for different OS versions.
Specifically I am trying to detect if a user is running Windows 7 64-bit.

How do I detect if an arbitrary user is an administrator on a machine? I have the user's domain and username but not password. The user is NOT the currently logged in user,so I can't just use WindowsIdentity.GetCurrent.

I have an application that when it starts, it checks the internet to see if a new version is available. My problem is this: If there is no net connection, the program 'pauses' as it tries to check for the new version.
Is there a function that I can use to detect if the user is currently online, with a working connection?

I'm trying to work out how to detect if the user has pressed an f key I have this so far:
Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles Me.KeyPress
Label1.Text = e.KeyChar
End Sub
This detects when the user presses a character key and outputs it via Label1.text, but it doesnt work on all keys?

Dim hostname As IPHostEntry = Dns.GetHostEntry(TextBoxIP.Text)
Dim ip As IPAddress() = hostname.AddressList
TextBoxIP.Text = ip(0).ToString()
I have a windows form with the code above to get the ip address of the user. what would be the easiest way to get the country location of the user? based on the IP in the textbox. The solution doesnt need to be 100% accurate but good enough to work most of the time. the simpler the better.is there are any work arounds or built in fuctions for pulling a users country or language, this would be better than creating or managing a giant database.

Using MVC, EF 4.2. I am working on an application that has a comment section. Right now if a user enters a comment that contains HTML e.g.<b>text</b>and hits submit i get the message "A ptentially dangerous Request.Form value was detected..."How do i handle html on the way into the db? Should I just strip the html? Or encode it? I tried server.htmlencode the text but i still had the same error message.

If we format a value for percent "{0:#%}" then it will become 400%, and this also applies to all the 3rd party controls I've tried. I've used custom format as a workaround for this but perhaps you guys could enlighten me on this one. If a user inputted 4 for example then did the user intended 4% or 400%? If it were me that I would expect the 4 to be 4% rather than 400%.

I need to write a program allowing the user to enter up to five passwords at one time. I have the textboxes set the way I need. When the user presses the button, the code should check every password they ve entered, and flag any passwords that are invalid. A valid password includes the following:
At least 6 and not more than 15 characters
At least one uppercase alpha character
At least one lowercase alpha character
At least one numeric character
I'm a little confused about how to check each character of the entered passwords for these conditions.Because it must include alpha characters, I believe I have to do something with ASC and CHAR variables. This is my first post and I need to have this done within a few hours, haha. Help would be awesome.

No doubt a simple question, but I'm a beginner (I learnt GW BritingASIC in 3 months long ago - but after 6 months grappling with vb 2008 I am still bewidered).
I have written a program that asks the user at run time to choose 1 of 40 buttons. These are themselves defined at run time. Whichever button is chosen the same algoritm will run (using different data). Question: To save writing the same Button_Click routine 40 times, what code should I write - and where in the program - to detect which of the 40 the user has chosen?

I need to detect whenever user clicks the mouse, no matter what form is selected at the given time.
I know that detected keypresses globally can be done through a Keyboard hook so I assume that i am going to need some sort of Mouse Hook.

How would I go about having my program monitor all open (or at least the current active) Internet Explorer windows and their current URLs? Basically, I want my program (running in system tray) to monitor the web page that is being viewed in an Internet Explorer window (NOT an integrated web browser control), and if it detects the loading of a specific URL address, execute whatever code.

Adding How would you detect if the user is using the computer? I want a program to detect if the user is using the computer (i.e. mouse and keyboard movements), and if the user doesn't type or move the mouse for a specific amount of time, it executes a command. Normally I would do this with the Application.Idle, but I want it to be detected throughout the system. Any starters?
