CB_SETITEMDATA Overview  Group

An application sends a CB_SETITEMDATA message to set the 32-bit value associated with the specified item in a combo box.

CB_SETITEMDATA 

wParam = (WPARAM) index;            // item index 

lParam = (LPARAM) (DWORD) dwData;   // item data 

 

Parameters

index

Value of wParam. Specifies the item’s zero-based index.

dwData

Value of lParam. Specifies the new value to be associated with the item.

Return Values

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 32-bit value in the lParam parameter of the CB_ADDSTRING or CB_INSERTSTRING message that added the item to the combo box.
