Delete key ListBox - 6/18/2008 9:51:26 PM

Hi,

I have the following sub that deletes a selected item from a listbox in a hta.
When hitting Backspace it works, but not with Delete.

Any idea why the Delete key doesn't work?

(Lists is a form tag, Samplecodes is the listbox (select tag) inside the form)

Sub Lists_onKeyPress
Dim objOption
If window.event.keycode = 127 or window.event.keycode = 8 Then
  For Each objOption in Lists.Samplecodes.Options
   If objOption.Selected Then
    objOption.removenode
   End If
  Next
End If

End Sub

Do you get any return if you do something like this?

If window.event.keycode = 127 then
Wscript.echo "127"
ElseIf window.event.keycode = 8 Then
Wscript.Echo "8"
End if

Hi SilentBob,

look at

and use the onKeyUp event (checking for Del == 46 and BS == 8).

Good luck!

Thx ehvbs,

onKeyUp (or onKeyDown) worked with window.event.keycode = 46
I don't get why it's 46 (ascii for . which is del on the numpad).
When using onKeyUp it acts as a del key (not . on numpad), when using onKeyPress it acts like . (dot)

Hi SilentBob,

you are welcome. To understand (the difference between) key and character codes (and
which event delivers what kind of code) just read the intro in the second link I gave you (again).

Good luck!
