Creating Listboxes "on the fly"

[vonehle]

Let's say I ask the user for a number between 1 and 10, then they click a button. How would I then create that same number of listboxes to appear on a form? I know I could create them and make them visible after the number is entered, but I don't want to have to do it that way.

One way would be to have a control like a placeholder (not sure if desktop has that) and then create listboxes in code and add them to your placeholder.

Try something like (not tested):

[tt]
'Validate that user input is a valid number between 1 and 10
'Result of validation would leave number in an Integer variable called UserInput
'Then ...
For a As Integer = 1 To UserInput
Dim lb As New System.Windows.Forms.ListBox
'Do any required positioning here (ie set lb.Top, lb.Left, lb.Height and lb.Width etc.)
'You might also want to look up using AddHandler if you want the list boxes to respond to events
Me.Controls.Add(lb)
Next
[/tt]

Hopefully this will point you in the right direction.
