shfolder.dll - File Not Found

[Jerry West]

I installed VB6 onto a Vista system to check some legacy code. When I run my
project, the code where shell folders are determined, I get the following
error when using the API:SHGetFolderPath

Error #48: File Not Found

I checked and shfolder is definitely in the sytem32 folder. But of course,
the legacy code is expecting the pre-Vista version of shfolder.dll. Has
there been so much change in this file that it would return a file not found
message. Anybody have any background info on this issue they can share?

Much appreciated!!

Not enough information.

The 'file' hasn't changed but due to UAC, compatiblity, and to some degree
64-bit/wow issues, permissions and 'views' have certainly changed. ie, what
may 'exist' in some situations, may not 'exist' in another.

You might check out the new group -
"microsoft.public.vb.vista.compatibility".

Well, I certainly should have mentioned that not only am I running the
legacy code within the VB6 environment but the platform is a x64 bit system.
The legacy code was compiled on a 32bit system.

I am running the IDE in "Start as admin" mode.

I'm not convinced the error is the result of the 32-bit versus 64-bit
difference. Am I completely off track here? Any further suggestions?

Have you looked at
http://msdn.microsoft.com/en-us/libr...81(VS.85).aspx, and understand
what it says about the version on Vista?

Also, it seems you think the error is indicating it cannot find the dll
itself. It seems to me the message means that it cannot find whatever the
folder id you are passing into the function.

error when using the API:SHGetFolderPath

The shfolder.dll has been designed primarily for Windows 9x and NT <= 4
with IE <= 4. You shouldn't use this on newer versions of Windows. Use the
following shell procedures instead:
SHGetSpecialFolderLocation()
SHGetSpecialFolderPath()

Error #48: File Not Found

VB6 throws that error when there is something wrong with the declaration or
the way the function was called, and doesn't necessarily mean that the file
was not found.

Please post the function declaration and how it's called.

[Jerry West]

It seems what I am doing should be supported based on the MSDN article
indicated by a previous post on this thread. The call I make looks like
this:

'Declare Function SHGetFolderPath Lib "shfolder.dll" Alias
"SHGetFolderPathA" (ByVal hwndOwner As Long, 'ByVal nFolder As Long, ByVal
hToken As Long, ByVal dwReserved As Long, ByVal lpszPath As String) As 'Long

' sFolderPath$ = Space(MAX_PATH)
' alFolders&(iIdx%) = 48
' SHGFP_TYPE_CURRENT = 0

lRet& = SHGetFolderPath(frmMain.hWnd, alFolders&(iIdx%), 0&,
SHGFP_TYPE_CURRENT, sFolderPath$)

Like I said, works fine pre-Vista.

I don't have vb 6, but the code runs on vist from .net 2008. With a
non-admin user, I get a path that is not a valid path.
The folder returned does exist for an admin user.

Presumably the reason for this is what the documentation on
SHGetFolderPath() in the MSDN states on the parameter 'nFolder': "Only real
folders are valid. If a virtual folder is specified, this function will
fail". Under certain conditions on Windows Vista your application somehow
works with virtual folder pathes, not with real ones (keyword is 'virtual
store').
