One of the problems on a ListBox when selecting all rows with the
usual loop is that the ListBox Change event will fire for each row
that is being selected. So, if you have 2,000 rows in a ListBox,
the Change event fires 2,000 times! And if you have (like I had)
code on the Change event to check for selected rows and do some
stuff, then you can imagine the problems it caused!
You cannot stop the Change event from firing, but what I usually do
is add a condition to run the code within the Change event.
Something like:
// ModificationLock is a property of Window or Listbox subclass,
and having it
// return like this short-circuits this event
If ModificationLock Then Return
// change code goes here
There are lots of reasons to have a ModificationLock property, not
just SelectAll. For example, if you have text in your
EditField.TextChange event, that event will also fire every time you
change the code in text. If you want to limit the code within the
event for just user modifications to the text, you can use a
ModificationLock. You would use it like:
ModificationLock = True
Me.Text = "something cool here"
ModificationLock = False
