C/C++ Coder: List View Item Control.

List View Item Control.

Here is a sample listing of code that will add bitmap IDs(win32 application) or ICON Ids to the list view control. few month back I made this to add a feature to my existing application module.
You cannot blindly add this to ur workspace since it need some modifications. Treat this as a code snippet or an example to make the target.!! Happy coding
