Syntax
CB_GETITEMDATA wParam = (WPARAM) index, lParam = 0
Parameters
index
Specifies the zero-based index of the item.
Return Values
The 32-bit value associated with the item indicates success. CB_ERR indicates that an error has occurred.
If the item is in an owner-drawn combo box created without the CBS_HASSTRINGS style, the return value is the 32-bit value contained in the lParam parameter of the CB_ADDSTRING or CB_INSERTSTRING message that added the item to the combo box. If the CBS_HASSTRINGS style was not used, the return value is the lParam parameter contained in a CB_SETITEMDATA message.
