Removing the border from an owner-drawn listbox

I've made an owner-drawn listbox by deriving CListBox, but I don't want it to have a border. Instead the border will be painted in the background of the parent dialog, so my开发者_如何学Go listbox will look like it has a custom border. How can I remove the border? Is there a flag or a function to override in my derived class?

You need to remove the WS_BORDER window style.
