Removing a control

I have a form with an array of controls that I created.

Dim ik as Integer ' is the count of these controls

I want to remove the last control and I use this code to do so

Controls.Remove(ListVItems(ik)) ' remove the control
ListVItems(ik) = Nothing ' I'm not sure this is necessary
ik -= 1 ' reduce the total
ReDim Preserve ListVItems(ik) ' reduce the array
Refresh

but nothing happens.
What have I done wrong?

Use RemoveByKey like:

Me.Controls.RemoveByKey("Button1")

or

Dim ControlToRemove as string = "Button1"
Me.Controls.RemoveByKey(ControlToRemove )

Hi broadbent;

Arrays are zero base in .Net so if ik is the total number of controls in the array then the last control in the array is ( ik - 1 ).

You're quite right, I forgot to say that ik is set =-1

But the answer is quite simple. Just asking the question normally helps.
These controls are NOT on the form, but on a panel (so that I can use the AutoScroll)
MainPanel.Controls does work.

I'm an idiot, and I will happily give the points to Kinger247

RemoveKey was not the answer by the way.
Remove(index) was just as good
