I would like to find the local path (C:\folder\folder\file) of a unc path of a shared file or folder (\\computer\share\folder\file).

I have come across two examples of code that get the job done in win2000, winnt and winxp, but none that do it in win95 and win98.

The code found for nt machines is as follows:
Dim sLocalPath as string

sLocalPath=GetLocalPath("MYDomain","ServerWhereTheUncPointsTo","\\Server\DatabaseShare")

'sLocalPath should hold the local path for UNC Share, this works even if its executing against itself


Function GetLocalPath(sDomName As String, sServer As String, sUNCShare As String) As String

Dim Fserver As IADsContainer
Dim Share As IADsFileShare


If Left(sServer, 2) = "\\" Then sServer = Mid(sServer, 3)

Set Fserver = GetObject("WinNT://" & sDomName & "/" & sServer & "/lanmanserver")

' Enumerate existing shares
For Each Share In Fserver

If Share.Class = "FileShare" Then
sShareName = Share.Name
sFullShare = "\\" & sServer & "\" & sShareName

If UCase(sFullShare) = UCase(sUNCShare) Then
GetLocalPath = Share.Path
End If

End If


sShareName = ""
sFullShare = ""
sLocalPath = ""

Next Share

Set Fserver = Nothing

End Function

Dim TempStr As MungeInt
Dim TempPtr As MungeLong
Dim STRArray(0 To 255) As Byte
Dim sBasePath As String

sTemp = Mid(sUNCPath, 3)
sServer = Left(sTemp, InStr(1, sTemp, "\") - 1)
sTemp = Mid(sTemp, InStr(1, sTemp, "\") + 1)
If InStr(1, sTemp, "\") > 0 Then
sShare = Left(sTemp, InStr(1, sTemp, "\") - 1)
sTemp = Mid(sTemp, InStr(1, sTemp, "\"))
Else
sShare = sTemp
sTemp = ""
End If

baServer = "\\" & sServer & Chr(0)
baShare = UCase(sShare) & Chr(0)

Result = NetShareGetInfo(baServer(0), baShare(0), 2, Buf)
mvarLastError = Result

If Result = 0 Then
Result = PtrToInt(TempStr.XLo, Buf + 24, 2)
Result = PtrToInt(TempStr.XHi, Buf + 26, 2)
LSet TempPtr = TempStr
Result = PtrToStr(STRArray(0), TempPtr.x)
sBasePath = Left(STRArray, StrLen(TempPtr.x))

Result = NetAPIBufferFree(Buf)

Server = sServer
GetLocalPath = sBasePath & sTemp
End If
End Function

I would like to make my application accessible to windows 95 and 98 machines. Does anyone know a way to do this with full compatibility?

Thanks!
