I am wondering how i would go about taking multiple items (randomly) from a listbox and displaying them in a label!Now this listbox wouldn't have to be visible, maybe i can do it without it even being a listbox?I want to have 25 labels and each one recalls a random value from the list (doesnt matter about being unique and the list will contain about 20-30 items)Im just a bit stumped on how to do it as ive done some looking into it but most people are asking for randomized numbers or unique items where as i need randomized items from a list which aren't unique!
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 have two listboxes and one text box. lbxData is already populated with strings (ex; car, boat, motorcycle) I have a text box (tbxRandom) for user input to choose the number of random strings they want generated and placed in the other listbox (lbxRandom) when clicking btnRandom. Here is what I have but keep getting an error. mylist.addrange(str) "value cannot be null. parameter name: collection
Dim Str As String 'Declare a List Dim myList As New List(Of String)
how to go about picking the random weapons. When you generate a random class, the user must first enter their current rank (level). This is because you are unable to use certain guns until you reach a specified level. This keeps the program from giving out guns the user can't use. What I am doing is allowing the user to give certain parameters as to what type of gun they want to use (or don't want to use). For example, I have checkboxes for the user to pick if they want assault rifles, SMGs, LMGs, Snipers, Shotguns, RPG, etc.
I did this in another version of this program I made, but the only option was to pick whether or not you wanted RPGs included. So, it was easy enough to check if the weapon was an RPG and if it was simply generate another random weapon. I could do this, but with the number of options there are, I don't think this would be the best solution.
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 have a listbox were users can add items to. Then i also have a remove button which removes the selected item. The listbox also has a datasource, so to remove an item i uses this
[code]...
But i also want sorting on the listbox. But when i clicks the remove button, it removes random items, not the selected one. How can i fix this?
The Textbox.Text will be a new Item in ListBox when Button1.Click I want button2.click to pick a random item from the listbox and display it as the label. Think of it as a random raffle picker lol.
I've been working on a little project recently which is a music player (unoriginal I know, but I'm just learning ). Basically, I want the items that have been added into the listbox to be remembered for the next time the application is opened so that you don't have to re-add the items. The items show up like this (because they are added from my documents): C:UsersEthanDocumentsMusicCage The Elephant - Aint No Rest For the Wicked.mp3?
I am using a listbox that is filled with a list of items from Database. When I am deleting an item from the listbox it is has to be deleted from Database, and that is all working fine.The problem is, even after deleting the item from the listbox, it is showing in the listbox, I have to close and restart the app to get the deleted item off from the listbox.
Is there any way to remove an item from listbox at the same time? I don't want to use timer to refresh is there any other way to refresh the listbox items???
I am making a program, and I have a listbox which will contain A big list of file Paths. I have two buttons Add and remove. Adding items is easy and I have done this. But removing items is the hard part because the listbox is multiselect. I have tried so many attempts It wouldn't be useful to post code. But the closest attempt is
I have a listbox control on my form that has SelectionMode as MultiSimple so I can select more than one item with my mouse. I added a contextMenuStrip to my form and added it to my listbox. I'd like the user to be able to select a few items in the listbox and when they right click > Copy it would copy the contents of the selected items to the Clipboard.
basically i had this problem before which i fixed with this code!
'REMOVE TIME If ListBox1.SelectedIndex <> -1 Then Dim Box As MsgBoxResult = MsgBox("Are you sure you want to remove this time?", MsgBoxStyle.YesNo)
[Code]....
It worked perfectly, all ive done to my code since is change the way the listboc is loaded / saved, it now comes from a .txt in My Documents rather than the C drive.
It now only deleted the top value of the group selected int he listbox and not all of them as it did before.
How do I disable buttons while there are less than 2 items in a listbox? I can't figure out how to do it. I'm a newbie in Visual Basic(programming at all)
how to write the items in the right listbox to a .txt file using StreamWriter. I need the output line to resemble:
"set sv_mapRotation map mp_abandon map mp_afghan map mp_boneyard map mp_brecourt map mp_checkpoint map mp_complex map mp_crash" The order should be just like it is in the right listbox.
This is the code that I have set up to begin this:
So I'm using the following code to add items into my list box, and I'm trying to get it to check the contents of the list box as well.
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click If ListBox2.Items.Contains(TextBox3.Text) Then MsgBox("Character already exists!") Else ListBox2.Items.Add(New LBnfo With {.v4 = RadioButton6.Checked, [Code] .....
But when I try to compare the two: If ListBox2.Items.Contains(TextBox3.Text) Then MsgBox("Character already exists!") Else
It doesn't show the message box even when the character actually does exist. I believe the problem is that I never do add the item really. I just use, "Return Me.character," which is assigned the value of Textbox3. So I just need to figure out how to check Me.character before returning it.
Ik heb met behulp van het volgende script de gegevens uit mijn listbox geexporteerd naar een ini file:
Private Sub saveButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles saveButton.Click If SaveFileDialog1.ShowDialog = DialogResult.OK Then
How would one go about checking a listbox's items for duplicates? Basically I need to write a program that displays the teams from a text file provided by my instructor, in alphabetical order. I can do that, but what I can't figure out is how to prevent the For loop from adding a duplicate team. What I'm envisioning is:
If teams(i).name is not in lstTeams.Items Then lstTeams.Items.Add(teams(i).name) End If
I have a program that compiles and works so far, except for the above problem and my alphabetical order (which I can probably figure out on my own:
Public Class danbrockteams Structure team Dim name As String
[Code]....
This works except that my listbox is filled with the team every player is in rather than just listing all possible teams. Not exactly looking for someone to just give me the answer, as I understand things best when figuring them out on my own, so I suppose a hint is what I'm really after.
I have made a little application for me and my friend to be able to chat with eachother, but now we have some unclear strings as you can see on the image below:
I would like to change for example the username or time date to a color or make it bold, could anyone tell me how to change ONLY that and not everything? I'd love to have such a thing as it makes the whole application way 'clearer'.
I am just wondering how I can make a listbox count the number of selected items and display it in a text label. My listbox selection mode is on MultiExtended.
The class Random is out right defective. It always produces the same random numbers in the same sequence. Things I have tried so far is every kind of seed you can think of as well as Randomize. The result is that I always get the same random numbers in exactly the same sequence.
I am practicing using the drawing commands, and have gotten a grass background and black happy face that moves around the background.It's a 10x10 grid of 50 pixels.I want (at the moment, when i press enter) it to generate a random number of trees (15 ~ 25) at random locations on the background. The program doesn't freak out about anything, and the variables seem to be right (using stop commands) but it's not drawing anything. Here is the code for the "GenerateTrees" command I have for when I press enter.
Private Sub GenerateTrees() NumberOfTrees = Int(Rnd() * 10) + 15 For i = 0 To NumberOfTrees - 1 bmap.MakeTransparent(Color.Fuchsia)
I've made an image viewer which opens a random image from a specified folder, but the random number is not that random at all... I've already used Randomize(), but without result.
