    My comment:
    On the picture below, the window with title "FolderView" and class "SysListView32" is actually a ListView control. The OS uses this ListView control for displaying shortcuts on the Windows desktop.


    For manipulating ListViews, Windows has an exhaustive set of LVM macros. Each LVM macro wraps a call to the SendMessage API function.

    Take in account that the Desktop ListView belongs to a different process. That makes calling the LVM macros a bit more complex than if both a caller and a ListView had shared the same process. Some memory needs to be allocated directly in the address space of that process, and some data moved back and forth.

    And here is one more thing. On 64-bit system the Desktop ListView obviously belongs to a 64-bit process. And remember that Visual FoxPro is a 32-bit application.

    That 32 to 64-bit issue makes LVM calls that use the LVITEM structure even more convoluted. The structure clearly cannot be used as is. Instead some of its members (the pointers) must be "padded" with extra bytes to fit a pattern recognizable by 64-bit OS.
