Looping through a listbox and removing items

Alien · 2014-11-02T21:22:14+00:00

This issue has come up rather unexpectedly and I can't seem to figure out what exactly the problem is. So, basically.. I am trying to loop through a listbox and remove any items that match up with the items/contents of another listbox. My code works fine.. up until I import a list of items that consist of over 300 into the first listbox then nothing gets removed. I know it sounds a little bit confusing.. but just take a look at my code and you can probably see what I'm talking about. Using FD As New OpenFileDialog() FD.Filter = "txt files (*.txt)*.txtAll files (*.*)*.*" If FD.ShowDialog = Windows.Forms.DialogResult.OK Then WordBox.Items.Clear() WordBox.Items.AddRange(IO.File.ReadAllLines(FD.FileName)) For Each item In Listbox2.Items For i As Integer = WordBox.Items.Count - 1 To 0 Step -1 If WordBox.Items(i).Contains(item.ToString) Then WordBox.Items.RemoveAt(i) End If Next Next End If End Using Any help is appreciated! Thanks
