shBrowseForFolder - validating selection?

[Lance Edmonds]

Folks,

I'm trying to validate local folders with shBrowseForFolder() and BrowseCallbackProc() so I can disable the OK button for non-local drives/folders.

While I can reject most network connections by testing the path, thus:

CALLBACK FUNCTION BrowseForFolderProc
    IF CBMSG = %BFFM_INITIALIZED THEN
        DIALOG SEND CBHNDL, %BFFM_SETSELECTION, %TRUE, CBLPARAM
    ELSEIF CBMSG = %BFFM_SELCHANGED THEN
        DIM zBuffer AS ASCIIZ * %MAX_PATH
        CALL SHGetPathFromIDList(BYVAL CBWPARAM, zBuffer)
        IF ISFALSE CBWPARAM OR ISFALSE LEN(zBuffer) OR _
            ISFALSE (GETATTR(zBuffer) AND %SUBDIR) OR _
            MID$(zBuffer,2,1) <> ":" THEN
            DIALOG SEND CBHNDL, %BFFM_ENABLEOK, %FALSE, %FALSE
            BEEP ' test only - not for final version
        END IF
    END IF
END FUNCTION

However, if I have shortcuts to network drives in my "Network Neighborhood" section (Win2K), the root names are detected as folders on the local PC, so the OK button is left enabled.

Does anyone have any ideas how to reliably detect the selection of one of these shortcut names?

Does this help?

BIF_DONTGOBELOWDOMAIN
Does not include network folders below the domain level in the 
tree view control.

BIF_RETURNONLYFSDIRS
Only returns file system directories. If the user selects 
foldersthat are not part of the file system, the OK button is grayed.

Lance,

I don't know anything about Windows shortcuts, but if the
shortcuts contain the drive letters for the programs/folders,
then you could try using:

L1 = GetDriveType(A$)

A$ = ASCIIZ containing root path of drive in question

L1 = UINT

If the drive letter queried is a Network drive,
L1 will return %DRIVE_REMOTE

Hope that helps!

Thanks for the ideas folks, but the problem is not quite straight forward...

Yes, I'm using %BIF_DONTGOBELOWDOMAIN and also %BIF_RETURNONLYFSDIRS (and I've experimented with %BIF_RETURNFSANCESTORS). The code above excludes any folder name whose 2nd letter is not a colon (truely Mapped drives will be ok), but the key problem is shortcuts contained in "My Network Places" cannot be discriminated from (what I call) "real" folders.

For example, "Computers Near Me" is returned from ShBrowseForFOlder as "C:\Documents and Settings\Administrator\NetHood\Computers Near Me".

Any ideas how to exclude a name that appears as a child of "My Network Places" in the list.

Thanks!

Have you checked what attributes are set for it? Some folders, like
Recycled have Directory+Hidden+System set, others may have other
combinations. Maybe this one has some other unique combination one
can use? Just a wild idea..

You talk that you are interesting in local folders.
If so, how can "Computers near me" appear ?

Do you restrict selection by BROWSEINFO.pidlRoot = "My Computer" ?
