How could I insert a bitmap or other image objects in a CListCtrl in MFC?

I want to list the thumbnails of a set of photos in a listctrl. But the only way to achieve this is to use the setImageList method to bind a image list to the CListCtrl object and insert items like this: InsertItem (int nItem, LPCTSTR lpszitem, int nImage). I also must modify the listctrl's style by ModifyStyle(LVS_TYPEMASK, LVS_ICON) to force it to display the icon of each item.

I don't think this approach a good way to achieve my goal. Can I add items of bitmap or other image objects directly in a CListCtrl?

Thank you very much!

Given that you need these sorts of extended features, sounds like you must use owner-draw. A good example is here. It doesn't show how to draw the image, but once you've got the owner-draw procedure set up you should be able to use typical BitBlts to paint the images.

Why do you think it's not a good approach? Your other options are to make it an owner-drawn control and render the images yourself, or use a callback for the images via CListCtrl::SetCallbackMask.

List controls use image lists for a reason; the bitmaps are stored in a way that is most efficient for rendering the list control. You would be pretty hard pressed to do it any better.
