LB_SETTOPINDEX
An application sends an LB_SETTOPINDEX message to ensure that a particular
item in a list box is visible.
LB_SETTOPINDEX
wParam = (WPARAM) index; // item index
lParam = 0; // not used; must be zero
Parameters
index
Value of wParam. Specifies the zero-based index of the item in the list box.
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
If an error occurs, the return value is LB_ERR.
Remarks
The system scrolls the list box contents so that either the specified item
appears at the top of the list box or the maximum scroll range has been reached.
