How can I change color on Items in a listBox at runtime?

Question

I wondering how I can change colors on items in my listbox? I'm using the listBox in a C# windows program and not in a web application. Say that I have 3 items in my listBox. I want to change color on item 2. Then I press a button I want item 2 to change to default color and item 3 to change color. All that will I do in runtime. Can anybody help me please:-) If anybody know, how can I disable items at runtime? I'm using: Microsoft Visual C# .Net 2003 Microsoft .NET Framework 1.1 Sondre
