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.
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?

Can i select multiple items in a Checked list Box? I have been tryng for soemtime now but I just dont seem to get the multipe selectd items even when I put it in a loop! Listbox has the member of being Selected. A checklistBox doesn't why? I need to select mulitple items in a CheckedListBox and save it in a database.
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.

I want to retrieve all the items in a listbox with a For loop. there are only two itemsin the listbox. I'm able to retrieve the first item in the listbox when the counter of the for loop is 0. when it gets to 1 an IndexOutOfRange Exception is generated.
Here is my code. Dim i As Integer Dim count As Integer=Me.ListBox1.Items.count Dim sel As String For i=0 To count-1 sel=Me.ListBox1.Items.item(i).ToString MsgBox(sel) Next i
I have a quick question...is it possible to make a "for... each" loop that would go through each selected item of a listbox? What I want to do make sure there are no dupe names in the listbox.
I want to loop through all the items in the datagrid and compare them with a particular item(unique) present in the datagrid itself, and if it is not equal that unique item ("My Pipeline" is the name of that particular item) with which i want to compare rest of the items with then delete that item and move on to the next item and compare again.
I have this script which is designed to loop through all of the selected listview items, and delete them from the ftp server. - The list view item names are exactly the same name as they are on the FTP server.
For i As Integer = 0 To ListView1.Items.Count - 1 Dim ftp As New FTPclient(host.Text, username.Text, password.Text) ftp.FtpDelete(ListView1.SelectedItems(i).Text) Next
Some info: The FTP server works fine! I'm using it in other places in my script, and those functions work fine. ftp.FtpDelete works fine as a function, I've used it to delete single files before. It doesn't delete any of the files, it just gives me a load of exceptions.
