How to add items in to List Box in VC++ win32 applications?

We can add the items in to List Box in VC++ win32 applications using the following notification message.

int index = SendDlgItemMessage(hwnd, IDC_LIST, LB_ADDSTRING, 0, (LPARAM)"Hi there!");

As you can see, this is a pretty simple task. If the list box has the LBS_SORT style, the new item will be added in alphabetical order; otherwise it will just be added to the end of the list.

This message returns the index of the new item either way, and we can use this to perform other tasks on the item, such as associating some data with it. Usually this will be things like a pointer to a struct containing more information, or maybe an ID that you will use to identify the item, it's up to you.
