Question

I’m trying to dynamically create variables if possible.

I have a list box containing check boxes. The user selects items from it and the selections are then added to a database. They can select any number of items from the list (1-7). I have iterated through the selected items and added them to an arraylist.

I now want to store each selected item in a different variable to be added to the database. The idea is to use just one insert statement which is expecting 7 entries. If the user only selects say 2 items, these are inserted as well as 5 empty strings.

    Dim part1 As String = ""
    Dim part2 As String = ""
    Dim part3 As String = ""
    Dim part4 As String = ""
    Dim part5 As String = ""
    Dim part6 As String = ""
    Dim part7 As String = ""

    'add selected items to an array
    For i = 0 To listPart.CheckedItems.Count - 1
        selected.Add(listPart.CheckedItems(i).Text)
    Next

I’d like to do something like:

    For j = 0 To selected.Count
        part+j = selected(j)
    Next

This way I should have variables holding empty strings if the user does not select all 7 items

Answer 1

I don’t think dynamic variables can be created, or need to be created.

Objects like ArrayList, Array, List, and Collection support adding items ( similar to how you are describing adding dynamic variables)

If you are looking to add a database entry for each item in the listview it’s possible you could just loop through the listview

 For item as ListViewItem in listPart.Items
     'Save item.Text
 Next item
