I know there's a way to do this, but I can't find the code for it. Does anyone know where I can find the Subclassing code to hook my scrollbar to a listbox, on which I have removed it's scroll bar so that I may use my own. My scrollbar has a variable for percent, if that is needed. I want it to be able to have the user scroll my scrollbar and the listbox scrolls down. Any suggestions?
