An application sends a CB_SETITEMDATA message to set the value associated with the specified item in a combo box.
Syntax
To send this message, call the
SendMessage
function as follows.
lResult = SendMessage( // returns LRESULT in lResult
hWndControl, // (HWND) handle to destination control
CB_SETITEMDATA, // (UINT) message ID
wParam, // = () wParam;
lParam // = (LPARAM)(DWORD) lParam;
);
Parameters
- wParam
-
Specifies the item's zero-based index.
- lParam
-
Specifies the new value to be associated with the item.
Return Value
If an error occurs, the return value is CB_ERR.
Remarks
If the specified item is in an owner-drawn combo box created without the CBS_HASSTRINGS style, this message replaces the value in the
lParam parameter of the CB_ADDSTRING or CB_INSERTSTRING message that added the item to the combo box.
