Saving More Than One CheckListBox Lists?
Oct 23, 2011
I have 3 CheckListBoxes, and I want to save all of their "checked" states. I tried to change the code to save and load one to work for three, and this is what I came up with:
vb
Private Sub savechxlst()
Dim FileStream As New System.IO.FileStream("C:CheckedListBoxData.cld", IO.FileMode.Create)
[Code]....
Unfortunately, all this does is combine all of the checkboxes into one list (ChxLstSym), and leave the other lists (ChxLstAud and ChxLstEx) completely blank. By this I mean ChxLstSym ends up having 15 checkboxes instead of each of the 3 Lists having 5 checkboxes (Which is how it was before I saved and Loaded), though it does remember which boxes were checked originally.
Is there a way to fix this so that I can save and load the checked states for all three of the checklistboxes (ChxLstSym, ChxLstAud, and ChxLstEx) so that they are all in their own lists upon loading them?

I have a CheckListBoxthat is filled with items from an array. I want the user to be able to select the items they want to remove then press a button and have the items be removed from the array. I have never worked with a CheckListBoxthat before so I'm not really sure how to go about this. Here is what I have tried so far:
Private Sub btnRemove_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRemove.Click
Dim TempNameList As New ArrayList
If cmbRemove.SelectedIndex = 0 Then
TempNameList.AddRange(NameList)
Array.Clear(NameList, 0, NameList.Length)
When I re-display the array into the CheckListBoxthat it shows that nothing was removed from the array.

Is there a way to implement a new column with a header in a checklistbox in vb.net? I've done a bit of searching, but didn't find much on the topic. Should I just abandon the quest and use a listview or some other control?

I would like to make a checklistbox which relates to a database, in that there should be the same amount of Items in the check list box as there are records in the table.
i was going to make a for loop for the amount of records in the database each time adding a new item to the checklistbox but im really not sure how to do that!
Using command As New SqlCommand("SELECT player_name FROM player_table", _
connection)
Using reader As SqlDataReader = command.ExecuteReader()

I've searched the forums and have only found similar things for ASP but not this exact function in VB.
I've got a checklistbox in my program which has 8 choices. I'd like to append the selected indices (the text not the index number) to a textbox on my form. How would I do this?

I made a quick search but couldn't find any help I need to put the values of a checklist box into an array. I've found several solutions on the internet but all of these don't seem to work for integer arrays. This is what I've got so far
" Dim RemoveValues(checklistRemoveBrew.CheckedItems.Count - 1) As Integer
Dim C As Integer
For C = 0 To checklistRemoveBrew.CheckedItems.Count - 1
RemoveValues(C) = checklistRemoveBrew.CheckedItems(C)
Next "

Heres some test code I used. Just a checklistbox on the form with this code-behind:
Dim list As New List(Of String)
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
For i = 0 To 10
list.Add("Test " + i.ToString)
[code].....
I use a list to keep track of the items in the listbox, so if I remove one of those items from the listbox I want to also remove it from the list using the same index.If you use this code and load the form and then check all the items, youll notice that when you uncheck one it will remove the item and THEN also uncheck the next item...why is that?

I have a checked listbox which is populated with names(firstname & Surname), I also have a form that has been designed (layoutwise but with no code) to be populated with personal info such as name address,postcode,email address, sql database defined in the program that has a table called members that has the same column headings as the members form.
What i am trying to figure out is how i can commit personal information on my form to that database and copy the firstname and surname from that form to the checklist box if they dont exist? how do i go about this codewise?
