c++ - Removing the border from an owner-drawn listbox -

I have created a master-drawn list with CListBox, but I do not want it to be a border. Instead, the boundary will be portrayed in the background of the parents' dialogue, so my list-box will show that it has a custom limit how can I remove the limit? Is there a flag or function to override in my derived class?

You WS_BORDER window style.
