Hi,

I'm using office XP.
I create a list box , inside ListBox I have some items, when I press
up arrow and down arrow key, upper or bottom item is selected and this is done
without any key-press event subroutine, it is working automatically.

Is it possible somehow to disable this behavior ?
I want to make my own key press event for up and down arrow keys which will
select item, but only in case when some other condition meet .


For example I have in ListBox 10 items, selected item is on 4th place.
When I press up arrow key , event subroutine will start.
This event subroutine will check one condition (from some other subroutine) ,
if this condition is TRUE than selection in listbox will move on 3rd place.
If condition is FALSE than nothing happens, selection stays on 4th place.

Hi,

I added a checkbox to mimic the test condition. If the checkbox is check
Up key is allowed.

Private Sub ListBox1_KeyDown( _
ByVal KeyCode As MSForms.ReturnInteger, ByVal Shift As Integer)

If KeyCode = vbKeyUp Then
If Not CheckBox1.Value Then
KeyCode = vbNull
End If
ElseIf KeyCode = vbKeyDown Then
' test code hete
End If
End Sub

Cheers

Will this confuse your users ?
Sometimes UP works, sometimes not. The user will have to understand why,
otherwise they will think it is 'broken'.

Click to expand...

Users are usually confused, but they will learn :-).
And I can always put some message box with information what is happening.
I need this option because I need to perform some actions
in exact order so I need controlled movement in listbox.

In this case that I have now in list box are listed path to images (jpg).
On same user form I have image window.
When I select image path in list box , this image is displayed in
image window.
Images are located on server and sometimes is needed cca 1s to display
image after selecting in list box.
So if user press too fast up and down arrow keys it is possible that
some images are skipped (not displayed in image window) and
this situation I want to avoid.

So I want that when user press, let say key down, in list box image path is selected,
in image window soon image will be displayed.
But until image is not displayed I want to disable up-down key.
