If ListBox1.Items(0).ToString = Nothing Then

Hi i keep getting an error here and cant seem to fix it :/

VB CODE

Code:

---

    Private Sub Button10_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button10.Click

        If ListBox1.Items(0).ToString = Nothing Then
            MsgBox("this is nothing")
        Else
            MsgBox("something is there")
        End If

    End Sub

---

ERROR:
System.ArgumentOutOfRangeException was unhandled
Message="InvalidArgument=Value of '0' is not valid for 'index'. Parameter name: index"

Now i know that the error means that there there is nothing in "0" but my code above should check that but its not :/

What have i done wrong ?

Thanks for any help

Try: If ListBox1.Items.Count = 0 Then

vb Code:

If ListBox1.Items.Count = 0 then
   'no items

The actual problem is you are calling .ToString on ListBox1.Items(0).

When Listbox1.items(0) is nothing, you can't call a method on it, because its not a valid instance of an object.

Code:

---

Private Sub Button10_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button10.Click

        If ListBox1.Items(0) is Nothing Then
            MsgBox("this is nothing")
        Else
            MsgBox("something is there")
        End If

    End Sub
