| Windows 95: wParam is 16-bits
|
|
|
LB_GETTEXT
An application sends an LB_GETTEXT message to retrieve a string from a list
box.
LB_GETTEXT
wParam = (WPARAM) index; // item index
lParam = (LPARAM) (LPCTSTR) lpszBuffer; // address of buffer
Parameters
index
Value of wParam. Specifies the zero-based index of the string to retrieve.
Windows 95: 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 listbox is limited only by available memory.
lpszBuffer
Value of lParam. Points to the buffer that will receive the string. 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
characters, of the string.
Return Values
The return value is the length of the string, in characters, excluding the
terminating null character. If index does not specify a valid index, the return value is LB_ERR.
Remarks
If you create the list box with an owner-drawn style but without the
LBS_HASSTRINGS style, the buffer pointed to by the lpszBuffer parameter will receive the 32-bit value associated with the item (the item
data).
