Current Windows Desktop Path

Hi! Does anybody know of a way to extract the current desktop path from the system? I know that in NT for example, each user can have a different desktop path. It also varies between the standard location in Win95 and WinNT, and I would like to be able to find out the correct path for the current user.

Can anybody help me?

Code:

---

Private Const g_sNULL$ = ""            'Empty string
Private Const g_sSepDir$ = "\"          'Directory separator character
Private Const g_sQuote$ = """"

Enum genErrors
    genUnknownError = vbObjectError + 512 + 1000
End Enum

Marty, how does that get the Desktop directory?

I have some code here that I dug up from MS and trial and error. I put it into a class module, but you can put this in a standard module or form, you will have to change the API declare (public/private) depending on which....

The catch: requires IE4 and above.

Code:

---

Public Enum fFolderNames
    f_STARTMENUPROGRAMS = &H2
    f_MYDOCUMENTS = &H5
    f_FAVORITES = &H6
    f_STARTUP = &H7
    f_RECENT = &H8
    f_SENDTO = &H9
    f_DESKTOP = &H10
    f_NETHOOD = &H13
    f_FONTS = &H14
    f_SHELLNEW = &H15
    f_ALLUSERSSTARTMENU = &H16
    f_ALLUSERSPROGRAMS = &H17
    f_ALLUSERSSTARTUP = &H18
    f_ALLUSERSDESKTOP = &H19
    f_TEMPINTERNETFILES = &H20
    f_COOKIES = &H21
    f_HISTORY = &H22
    f_WINDIR = &H24
    f_SYSDIR = &H25
    f_PROGRAMFILES = &H26
    f_MYPICTURES = &H27
End Enum

Private Declare Function SHGetFolderPath Lib "ShFolder" Alias "SHGetFolderPathA" & _
(ByVal hwnd As Long, ByVal f As Long, ByVal TOKENHANDLE As Long, & _
ByVal FLAGS As Long, ByVal lpPath As String) As Long

Public Function GetFolderPath(FolderName As fFolderNames) As String
       
    Dim Path As String * 260
    Dim ret As Long
    ret = SHGetFolderPath(0, FolderName, 0, 0, Path)
    GetFolderPath = Path
   
End Function

---

Usage: MSGBOX GetFolderPath(f_DESKTOP)

I guess I misread the original question. My code yields the path to the system folder. C:\WINNT for example.
