Below is the code I have written but there seems to be a problem with the [InputBox] statement at line 11 & 15. Every time that I click cancel the program crashes. This code is just a random password generator. [code]

I have a simple windows application that pops up an input box for users to enter in a date to do searches.
How do I identify if the user clicked on the Cancel button, or merely pressed OK without entering any data as both appear to return the same value? I have found some examples of handling this in VB 6 but none of them really function in the .NET world.
Ideally I would like to know how to handle the empty OK and the Cancel seperately, but I would be totally ok with just a good way to handle the cancel.

Is there any workaround to the input box sending an empty string when you press cancel? I have a web research function on my program:
Private Sub Button17_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button17.Click
Dim temp7 As String = InputBox("Enter the album name.")
[Code].....
Basically, it provides an input box, you type in the album you want information on, and it will take you to a web page to give you information.
But when you press cancel, it does all of that anyway. It just takes an empty string...
Is there a way I can have the user press cancel to the input box and simply nothing happens? As far as I can tell, it ignores the "If windows.forms.dialogresult.ok." line...

I validate a DataGridView with the CellValidating-eventhandler.That works fine. However, I want to avoid validating when the user presses the Cancel button. In the sequence validation occurs before the event CancelButton.Clicked.

Not so much a VB question more of a Net question.Does anyone have a logical explanation as to why the Maximum value of a Scrollbar is impossible to reach by user interaction?The documentation explains clearly the how, it just gives no reason for the why.

I am working on a poker game and I have the game setup the way I want it in terms of graphics and I have the code programed to deal the cards out exactly how I want them. Granted, the code is very simplistic, but functional for a new programmer like myself. I'm sure there are other more efficient ways to code my game, but I like mine so far because I can at least understand the majority of it. With that being said, here are a few problems and questions that I have.
1. How come when all 12 cards are dealt out I have some cards repeating in the game? For example, I get queen of diamonds in more than one picture box when I only want the card to be dealt once and then removed until the next game.
2. I was hoping to have a button 3 to clear all the boxes, basically resetting the game to the next game. When I hit button 3 it only clears the contents of picturebox 10 and 12.Other notes: I have the deal down the way I want it. It deals the first 10 picture boxes and a second button deals the 11 and 12 picture boxes.
3. I know this is my next step so I want to post it with the code I currently have. I want to start taking my project one step further by evalutating each of the three rows of cards (3 rows of 3 cards each - I'm not worried about the dealers hand (picture box 10, 11, 12 yet). So I want to evaluate a row of pictureboxes against a "pay scale" and display the win in a text box or label next to the 3 card hand. For example, Q of diamonds, Q of Clubs, Q of spades would win 15, etc. ( have a weird feeling I may have to change the names of the cards (I have them named card1, card2, etc. right now) to something that identifies them in order to evaluate the hands.
Here is the code that I currently have. I'm using visual basic.
Public Class Form1
Dim Rndm As New Random
Dim myPB(11) As PictureBox
Dim HiddenCards As New List(Of String)
[code]....

I'm trying to make a mastermind game program with visual basic. I started of creating the combination maker for the start of the game. Hoever, in my version i don't want any colors to repeat. I used the random function independently to get numbers from 1 to 6. Each number has a corresponding color. The problem, the values still repeat sometimes.
Here's my code for that part:
Randomize
a = Fix(Rnd * 6) + 1
txtA = a
If a = 1 Then

How do I (programmatically) find out the key repeat delay and key repeat rate for a system?
A solution that works on any/all .Net capable platforms would be ideal, but the key target OSes would be XP, Vista, and 7.

I have an assignment that asks me to:
1. create a button
2. when that button is clicked, an inputBox will appear to ask the user how many words they will enter.
3. then display an inputBox for each word.
For example, when the first inputBox appears, I enter "3" (meaning that I will enter 3 words).Then there should be 3 more inputBox (each inputBox allows me to enter only 1 word)After I enter the third word, there will be no more inputBox.How can we FLAG (stop) the inputBox, or let the inputBox know when to stop showing up?

If Not IsNumeric(textbox1.Text) Then
KeyAscii = 0
End If
I learned in MSDN and wrote those code,but it doesn't work. This code " KeyAscii = 0" it's not correct, I just want to cancel the input, for instance,if user input 1a, then "a" will be not inputted into textbox, but "1" will leave.

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.....
