Puedes hacer:
Const CSIDL_DESKTOP = &H0
Const CSIDL_PROGRAMS = &H2
Const CSIDL_PERSONAL = &H5
Const CSIDL_FAVORITES = &H6

Const CSIDL_RECENT = &H8
Const CSIDL_STARTMENU = &HB
Const CSIDL_COMMON_STARTMENU = &H16
Const CSIDL_COMMON_PROGRAMS = &H17
Const CSIDL_COMMON_STARTUP = &H18
Const CSIDL_COMMON_FAVORITES = &H1F
Const MAX_PATH = 260
