Hi JLGWhiz,
I'll try to explain some more details hopefully they will clarify the
problem to you.
In Sheet1, i have some checkboxes for users to select from. Then there is a
commandbutton with caption 'Search'. The code behind this button searches for
the criteria selected by the users in the checkboxes and puts the results in
Sheet2 in 'MyRange'. The Listbox in sheet1 is then supposed to have its
ListFillRange property equal to MyRange.
All this goes well .. except that the items in the list don't get displayed
inside the listbox straight away. I found out that i first have to give the
screen a little 'tingle'. If i simply scroll down the screen and up again,
the list is there. Or if i minimize the window then maximize it, i can then
see the search results listed in the list box. It's as if the screen is not
refreshing its pixels unless it's 'tickled'!! I also noticed if i had another
application active on the screen in front of my sreadsheet, then i close this
other application, i can still visually see part of it within the listbox. Do
you know what i mean? Do you think this is a hardware problem related to the
capacity of the screen to refresh? or is it a programmatic problem with the
listbox? is there anyway i can go around this problem in my code. Is there
such a thing as: Screen.refresh?
PS i tried the spreadsheet in 3 other computers (fairly new ones) and the
same thing happens.
Thanks again for all your help.

On second thought, after reading your post again, if you are expecting the
listbox to automatically add items as you add items to the named range, it
will not do that. It must be re-initialized to reload the ListFillRange.

I have a ListBox object (from Controls toolbar) in Sheet1. The ListFillRange
property is a defined range named 'MyRange' (located in Sheet2). 'MyRange' is
dynamic. It changes in length according to some calculations. I want the
ListBox items to change accordingly. I'm using the following code to first
set the ListFillRange to nothing then set it to MyRange. However, the list
doesn't get refreshed straight away. The list items get updated only when i
manually activate a different worksheet then go back to Sheet1. How can i fix
that? is there such a thing as 'refreshing' the listbox programatically? i'm
using Excel 2003
Here is my code:

' delete the old range
ActiveWorkbook.Names("MyRange").Delete

[code to do some calculations]

' give the new range the same name
Sheets("Sheet2").Range("A5:B5").Select
Range(Selection, Selection.End(xlDown)).Select
ActiveWorkbook.Names.Add Name:="MyRange", RefersTo:=Selection

Sheets("Sheet1").activate

' assigning the newly named range to the listbox
Worksheets("Sheet1").OLEObjects("ListBox2").ListFi llRange = ""
Worksheets("Sheet1").OLEObjects("ListBox2").ListFi llRange = "MyRange"

exit sub

Everything goes fine except that the listbox doesn't show the new items
directly. Why do i have to log out of Sheet1 then go back to find the new
results in the listbox?
Any help will be greatly appreciated.
Cheers, Tendresse
