there ya go in your event that you want to see the selected items you can do it this way.

        Dim oItem As Object
        Dim s As String
        For Each oItem In ListBox1.SelectedItems
            s &= CType(oItem, String) & vbCrLf
        Next

        MsgBox("Results: " & vbcrlf & vbcrlf & s)

ok, thanks

I also have been trying to make it compare the text to what is hardcoded

example

in my listbox1 I have

Dog
Cat
Bird

I am trying to have a code that only does something when the current selection is Cat

I was tryingto do

if listbox1.items.item(o) = "Cat"

but nothing I also tried

if listbox1.selecteditem("Cat") = "Cat"

but it does work right

I need something that will only work if the current selection is hit

in vb6

I used
if listbox.text = "Cat" then

and it worked

any ideas of what to do

       Dim oItem As Object
        Dim s As String
        For Each oItem In ListBox1.SelectedItems
            if (CType(oItem, String) = "Cat") then
                   'Run something
            end if
        Next

if you don't like the for each solution you can do it by a count as well

        Dim i As Integer
        For i = 0 To ListBox1.SelectedItems.Count - 1
            If (CType(ListBox1.SelectedItems.Item(i), String) = "Cat") Then
                MsgBox("Run something")
            End If
        Next

the reason your's wasn't working is that you were most probably comparing to an object which is what the selected item returns so you have to cast it to a string then make the comparison.

Cheers
