LB_GETTEXT message

Gets a string from a list box.

Parameters

wParam

The zero-based index of the string to retrieve.

Windows 95/Windows 98/Windows Millennium Edition (Windows Me) : The wParam parameter is limited to 16-bit values. This means list boxes cannot contain more than 32,767 items. Although the number of items is restricted, the total size in bytes of the items in a list box is limited only by available memory.

lParam

A pointer to the buffer that will receive the string; it is type LPTSTR which is subsequently cast to an LPARAM. The buffer must have sufficient space for the string and a terminating null character. An LB_GETTEXTLEN message can be sent before the LB_GETTEXT message to retrieve the length, in TCHARs, of the string.

Return value

The return value is the length of the string, in TCHARs, excluding the terminating null character. If wParam does not specify a valid index, the return value is LB_ERR.

Remarks

If the list box has an owner-drawn style but not the LBS_HASSTRINGS style, the buffer pointed to by the lParam parameter receives the value associated with the item (the item data).
