Kimmo's ListView Subitem Backcolor

I am currently working on a gantt chart activex and have been searching the internet for code to update the backcolor of listview subitem. I finally figured it out last night after much research. This code enables one to change the listview subitem backcolor to any color that you want. I have off course ported this over an activex for my Gantt chart. You can see the post named Gantt Chart Platform here in psc. Enjoy.
