Thread moved to Windows Forms forum, this is more specific for your topic than VB.Net General forum.

Private Sub CheckedListBox1_ItemCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs) Handles CheckedListBox1.ItemCheck
    If Me.CheckedListBox1.CheckedItems.Count = 3 AndAlso e.NewValue = CheckState.Checked Then
        e.NewValue = CheckState.Unchecked
        MsgBox("You can only check 3 items.")
    End If
End Sub
