An application sends an LB_SELITEMRANGEEX message to select one or more consecutive items in a multiple-selection list box.
LB_SELITEMRANGEEX
wParam = (WPARAM) wFirst; // first item
lParam = (LPARAM) wLast); // last item
Parameters
wFirst
Value of wParam. Specifies the zero-based index of the first item to select.
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.
wLast
Value of lParam. Specifies the zero-based index of the last item to select.
Return Values
If an error occurs, the return value is LB_ERR.
Remarks
If the wFirst parameter is less than the wLast parameter, the specified range of items is selected. If wFirst is greater than wLast, the selection is removed from the specified range of items.
Use this message only with multiple-selection list boxes.
This message can select a range only within the first 65,536 items.
