CB_GETLBTEXT Overview  Group

An application sends a CB_GETLBTEXT message to retrieve a string from the list of a combo box.

CB_GETLBTEXT 

wParam = (WPARAM) index;                // item index 

lParam = (LPARAM) (LPCSTR) lpszBuffer;  // address of buffer 

 

Parameters

index

Value of wParam. Specifies the zero-based index of the string to retrieve.

lpszBuffer

Value of lParam. Points to the buffer that receives the string. The buffer must have sufficient space for the string and a terminating null character. You can send a CB_GETLBTEXTLEN message prior to the CB_GETLBTEXT message to retrieve the length, in bytes, of the string.

Return Values

The return value is the length of the string, in bytes, excluding the terminating null character. If the index parameter does not specify a valid index, the return value is CB_ERR.

Remarks

If you create the combo box with an owner-drawn style but without the CBS_HASSTRINGS style, the buffer pointed to by the lpszBuffer parameter of the message receives the 32-bit value associated with the item (the item data).
