The goal is simple... generate a set of random numbers with a certain range (e.g., 1-6, 5-10) with no repeats. I tried using a system with arrays where everytime a number has been generated, its marked as "used" and then the program is required to generate a new number. But it doesn't work!
Public randomnumgen As New System.Random
Public randomnum As Integer
Public iCounter As Integer
Public GotIt(7) As Boolean
[code]....
What is missing is a way that when I give a print click on the quantity of copies informed skirt with sequential numbers without repetition

how can i randomize numbers between 1 and 200, but no number can be repeated
View 8 RepliesSay I am pulling the following table, I would then like to select an ID randomly. I understand how to select a random number using a Randomize() call followed by the relevant syntax but I want to pre-define the range.
i.e. Table Data
ID | Name
4345 Mike
3456 Lee
4567 John
There will be many more names but for this example you could use 3 or 4 etc..
I'm trying to shuffle a Euchre Deck and it works but I feel like I'm cheating. Is there a more concise way to randomize a list of numbers 1 - 24 and have no repeats? ex. 14, 3, 18, 23...
Dim Deck() As String = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24}
Dim A As New Random
Dim B As Integer = A.Next(0, 24)
Deck(B) = "9 of Clubs"

View 1 RepliesI cant figure out the code for vb.net that would randomize the interval of a certain timer. For each a = a + 1, there would be a different interval, and for each a = 1, a = 2, a = 3 etc. there would be a different text that will be shown on a label.

View 1 RepliesSay you press and hold down a letter on your keyboard. The first letter gets added, there is a delay and then it repeats quickly on screen. Is it possible to skip this delay and go straight to the repeating part? I realize this might not be a visual basic question as much as a windows question, but if there is some way of toggleing it through my program, or using a workaround, i would like to hear the alternatives ^^ Setting the windows setting to fastest still has a small delay and others users would still experience it on other computers.

View 2 RepliesI hv an array which contains

and i want to copy Array 1 value into Array 2 ..... but it pick value from Array1 from randome postition
so in array2 value go like this
[code...]
I was thinking if I can create a code that creates 8 Labels, and each label will show someone's name. The name is not generated, it is randomized. But I Don't want to see 2 same names in 2 different labels. So what I came across is this:
First, I will make an array variable (0 to 8) as String, I will declare each person's name here, the 0 is not used. I Will call this "Names"Second, I'm going to make an array variable (0 to 8) as Boolean. Original State is False. I will call this "Type"Third, I will make another array variable (0 to 8) as Integer, this one is empty. I Will call this "Empty". Original value = false
The Point is that the application will randomize a number between 1 to 8, just say that the randomized number is "x". Then I will take Names(1) and fill it in Empty(x), and set the Type(x) to True, and keep looping. If the application finds the Type = False, then the application will randomize another "x". But after making the code, it seems that the numbers show up the same way everytime I run it. Even with the Randomize() statement.

how to have them all into a list and choose 1 randomly to webbrowser navigate
I wrote the following function to randomize a dictionary object:
Friend Function RandomizeDictionary(Of T)(ByVal oCollection As Dictionary(Of String, T)) As Dictionary(Of String, T)
Try
Dim oResult As Dictionary(Of String, T) = Nothing
[code]....
This code works fine on simple dictionary objects, but when I use it with complex types I get a type cast exception. For example, I have an object X that Inherits Dictionary (Of String, Class Y). If I call the randomize function on object X, I get the type cast exception. I don't really understand why it cares what the type of the dictionary value is, I thought that was the point of using generics.
In summary the following all work:
Dim x as New Dictionary (Of String, String)
Dim x as New Dictionary (Of String, Boolean)
Dim x as New Dictionary (Of String, Integer)
This does not:
Dim x as New Class X
Class X Inherits Dictionary (Of String, Class Y)

View 3 RepliesI have written an if...else statement which uses an array myArr and a string myStr as follows:

'Do stuff 1
ElseIf myStr= "xyz" Then
'Do stuff 2
ElseIf myArr.Length > 0 Then

It works exactly as I need. But It looks really confusing, mostly because the array length is checked twice. There must be a clearer way to write it, but I can't think of one. the order that each statement is executed is crucial. i.e. Stuff 1 has priority over stuff 2, which has priority over stuff 3.
I have a button that when you click executes a certain code, lets say I make a menu that when clicked on should execute the same code, so how can I do this without having to copy/paste the same code twice.

I need to stop the execution of a program in VB.net. Within a repeating structure the program checks whether a variable is true or false. When the variable is false I need to stop the program execution. I do not want to close the program but simply stop it. One way I found was raising an exception, but I would not want to display the error message to the user. What is the best way to do it ?

I'm getting a bit more fluent in VB.Net, but am still a bit green around the edges in certain aspects. I'm creating custom controls, and am starting to rely heavily on AddHandlers to manage them.Until recently, I didn't realize that you can add multiple event handlers for the same control and same address

The above code would create 10,000 copies of the same event, and if I would click on combobutton1, the event would fire 10,000 times. I only need to fire the event once, but sometimes my code is a bit circular, and there may be an instance where two or more addhandlers are designated for a given control and address. Is there a way to have a loop on my custom dispose event where it would look something like:

Or better yet, remove all events from a control(On a side note, is there any way in the debug mode to see all the active events attached to a control?)
