| Windows 95: wParam is 16-bits
|
|
|
LB_DELETESTRING
An application sends an LB_DELETESTRING message to delete a string in a list
box.
LB_DELETESTRING
wParam = (WPARAM) index; // index of string to delete
lParam = 0; // not used; must be zero
Parameters
index
Value of wParam. Specifies the zero-based index of the string to be deleted.
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.
Return Values
The return value is a count of the strings remaining in the list. The return
value is LB_ERR if the index parameter specifies an index greater than the number of items in the list.
Remarks
If an application creates the list box with an owner-drawn style but without
the LBS_HASSTRINGS style, the system sends a WM_DELETEITEM message to the owner
of the list box so the application can free any additional data associated with
the item.
