Multiselect Listbox add records

[samonwalkabout]

Its

If Not Me.List0.ItemData(vtlm) Then

is the same as


If Me.List0.ItemData(vtlm) Not NULL Then

It just tests to see if anythink is selected in the first list box. It looks at Null Not Null not true false.

You could say.

If Me.List0.ItemData(vtlm) null then

msgbox "null"

Else

'logical expression


I dont think thats the problem here i really need to know if

-- would the other method "rst.FindFirst " look at the contents of the destination list box to compare or the contents of the table?

And if it can how?

Thanks

Aha. If you want to check to see if anything is selected in a multiselect listbox, an easy method is:
Me.List0.ItemsSelected.Count

To look at the contents of any listbox, you need to know what feeds into it. You can use this expression:
strSQL=Me.List0.Rowsource
and strSQL will then be assigned a SQL string that will tell you what goes into the listbox. It will be in this form:
SELECT table.field FROM table;

When I typically tackle this problem, as I stated before, I copy all possible choices for both listboxes into a temp table. That way, I know what feeds into them. Then I just use a yes/no field to decide which record goes into which listbox.
