Get An Array Into Listbox And Then Randomize Items Into 4 Groups
Jun 7, 2011
I got the textbox and a listbox and a button, I can add names threw the textbox hit the button to add and it adds to the listbox, now I need to take the names from there and randomize them into 4 groups and make it into an array also, I just dont know how to take the names I entered and randomize them and put them into 4 different groups without repeating themselves, it is ok if three groups that have 5 and the fourth has 6. They just need to be randomized and put into 4 different groups,This is what I have, but I think its the wrong way to do this, to make the code work right atleast.[code]

so I am working on a program with items entered into a listbox. Then when the user clicks a button it will randomize the listbox items in just a random order obviously. I have tried adding it to an array and everything but I ended up just having to start over now because I couldn't find a solution. I can save the contents and everything I know how to do that it's just randomizing the items that I am struggling with. I have searched high and low and have yet to find a conclusion to my problem.

I know there's a one-liner piece of code that converts my Listbox Items to an Array.
I'm trying to save listbox contents to a file using System.IO.File.WriteAllLines.

I am trying to get the items out of a listbox and put into a text box .. I am putting the listbox items into an array and I keep getting this error: InvalidArgument=Value of '1' is not valid for 'index'. Parameter name: index
bolded code where this occurs here is my
Private Sub btn_BuildText_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_BuildText.Click
Dim delimiter As String 'Holds the String character representing the chosen delimiter
Dim i As Integer 'Loop counter

I have a huge assignment tommorow in which i have to make a trivia game on visual basic. In this game you have to be able to make your own questions (modify/delete etc). Basically I have one form where you can add questions into one listbox and answers into another listbox. Now i have another form with the actual game board. I want to load each individual listbox item from the other form into the array on the game board form. Example. the first item of form2.listbox1 into question(1)
I got this so far
Private Sub Form5_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim i As Integer

I am using VB.NET (version 2008). I have two types of items populating in a listbox (checked listbox). For example: lets say one is type "A" and other is "Type B". Their names maybe same so if the user sees those items in listbox then he won;t be able to determine their type until he click on them and checks out its properties. I wanted that I add each item to listbox and colour them so that blue for example means type "A" is there and red means the other. So this way I will be able to know at a glance that how many item of what type is present. I guess it may not be possible to do that in a standard checkedlistbox. I am also using component factory's krypton controls which enhance the gui of an application. But I dunno if I can progress using that.

I am making a random name generator. what I got is a large list of first names in listbox1 and a large list of last names in listbox2. when I hit a button, I am randomly pulling a name from both listboxes and putting them into 2 textboxes. for some reason they arent always random. I would say out of 50 names I will get 2 or 3 sets that are identical. why??keep in mind I probably have 400 first names and 200 last names. I should never get a duplicate! here is my
'randomize first names
Dim rnd As New Random()
Dim randomnumber As Integer = rnd.Next(1, ListBox1.Items.Count)

I am currently using VB 2008 and there is a form I'm using which contains a listview control. I am dynamically filling the listview with groups and items. After I fill it up, it is supposed to look like this:
[CODE]...
Each item is specific for each group. The problem I have is that when I maximize the form to full size, and everything expands, the items change positions into something like this:
[CODE]...
How can I make the listview keep the items in the "row" view always, instead of the "column" view whether I maximize or not?

I 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.

So I want it to remove any text in the list box that has a "Job" in it and just replace it with a blank nothing.
Like if the listbox looked like this
Yardjob
jobsong
redjob
then it would change it to this
Yard
song
red
I also would like a way of removing any blank items from the listbox.

I've got an array containing lots of "Color" and I want to change the order of this colors (random) but with a password: so another user can get the "original" (and correct) sequence of the array only with the right password. How can I do this in Visual Basic .NET or C# ? Do have I to use a particular encryption engine?

I'm making an application that does some stuff involving the given subject, so this is very crucial to the completion and efficiency of my application.What I'm in need of today is simple (well, "seems" simple). I have one listbox that I want to populate with directories file's names. I don't mean the files inside the directories, but the names of the folders inside the directory.So, I have "c:empdog", I'd click on my button or whatever and search for the directory and I choose "temp", said listbox would show "dog".
UPDATE: Oh, BTW. It doesn't HAVE to be a listbox, it can be anything (IE: Textbox, Labels, Etc.).

Why is this code having the opposite effect? If It's checked in the checkedlistbox it's not check in my view, if it's not check in my checkedlistbox it is checked in the grid.
EDIT: More specifically. The CheckState.Checked is always the opposite. .Checked means it's not checked.
Private Sub CheckedListBox1_ItemCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs) Handles CheckedListBox1.ItemCheck

I have a program that will compare an array of grocery list items glist and an array of coupon item clist.When I compare the two and if there is a match somewhere in the array I want to have a picturebox visible.When there is no match, I want the picture box not to be visible. [code] The code seems to work great until I come to the else statement.When the code finds a match it displays the picture box and the msgbox without error, but as soon as the message box is cleared, even though i've input it as an ELSE statement, the picturebox goes false again.Does anyone have any idea of how I can "hold" the picturebox to stay visible while the match between the arrays exists?
