Listbox Multiple Line Remove
Jun 22, 2010
I'm having a little trouble deleting multiple lines for a listbox. I know how to remove a single line, which is this: [code]If I change the value for IndexOf to SelectedItems, I get an error stating that -1 is not valid for index.I am guessing this needs to be done using an integer array and a for each but I don't know how to do that. I really never bothered to look much into arrays.

I have 2 listboxes on my form.Listbox 1 - populated with "available" field namesListbox 2 - populated with "selected" field names.There cannot be the same field name in both listboxes - it's either one of the other.The logic I was going to apply was to populate Listbox 1 with every field name ... and then as I populated Listbox with the field names which the user has already selected, remove the corresponding item from Listbox 1.

I am making an application where the listbox will load a text file that contains a number of different strings on each line. I want my application to interact with the first line, then go back, interact with the second line, then go back etc etc. The number of lines that will be in the listbox isn't set, and will change according to the text file that is loaded.

I am having trouble removing a line from a text file. When I click on the button in order to remove the line it gives me an error that access to the file is not possible. Now I assume that the file is in use during me wanting to change it and therefore cant save it while it is loaded in ht application. I have tried a few things but cant seem to get it to work.Essentially what it does is that I have another dialog that a used can add data, the data is then written to the file FilingLocations.txt and then it saves it and loads it again. But once the line is no longer needed I would like to have the option to remove the line agaise.
Here is the code:
Private Sub cmdRemoveLocation_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdRemoveLocation.Click
[code].....
