Checkedlistbox

Im looking for some assistance...what im trying to do is check to see what items are checked and say if item 1 and 3 are checked do this but if 2 and 4 are checked do this...I've tried a bunch of code but nothing seems to work..im doing this all in VB

Private Sub btn_ok_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_ok.Click
Dim itemChecked As Object

For Each itemChecked In chklb_syscus.CheckedItems

If itemChecked = "ITEM1" And itemChecked = "ITEM2" Then

MessageBox.Show("ITEM 1 and ITEM 2 Was checked")

End If

Next
End sub

Would this code still work if say i have this setup

Item 1
Item 2
Item 3
Item 4

And a person selects Item 1 and Item 2 and Item 3....and i want it to do something
But if a person only selects Item 1 and Item 2 do something else. The problem i was runing into is when i program it to check to see if Item 1 and Item 2 are picked it would run the Item 1 and Item 2 code not the Item 1 /Item 2/ Item 3 code I guess i could do

if( checkedItems.Contains( m_SomeItems[0] ) && checkedItems.Contains( m_SomeItems[1] )) && checkedItems.Contains( m_SomeItems[2] ))

Your code is not quite right indeed. You are iterating over a collection and checking whether the current items equals two different values... which is always false.

I have made a piece of sample code in C# (sorry), but if you study it just a little bit you will see how it works.
I add a list of objects to the listbox (strings), and later on I compare the reference of the objects using CheckListBox.CheckedItemCollection.Contains.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace CheckedListBoxTest
{
    public partial class Form1 : Form
    {
        private string[] m_SomeItems = new string[ 4 ];

        public Form1()
        {
            for( int i = 0; i < m_SomeItems.Length; ++i )
            {
                m_SomeItems[ i ] = String.Format( "Item {0}", i );
            }

InitializeComponent();
}

        private void Form1_Load( object sender, EventArgs e )
        {
            foreach( string item in m_SomeItems )
            {
                this.checkedListBox1.Items.Add( item );
            }
        }

        private void button1_Click( object sender, EventArgs e )
        {
            System.Windows.Forms.CheckedListBox.CheckedItemCollection checkedItems = checkedListBox1.CheckedItems;
            if( checkedItems.Contains( m_SomeItems[0] ) && checkedItems.Contains( m_SomeItems[1] ))
            {
                MessageBox.Show( "Items 1 and 2 checked!");
            }
            if( checkedItems.Contains( m_SomeItems[2] ) && checkedItems.Contains( m_SomeItems[3] ))
            {
                MessageBox.Show( "Items 3 and 4 checked!");
            }
        }

Easy, just check whether all three items were checked first and act upon it. If not all three were checked but the first two were checked, do something else.
