If (lpIDList) Then

sBuffer = Left(sBuffer, InStr(sBuffer, vbNullChar) - 1)
MsgBox sBuffer & Path
End If
End Sub

Use this code to get the computer name:

Private Declare Function GetComputerName& Lib "kernel32" Alias "GetComputerNameA" _
(ByVal lpBuffer As String, nSize As Long)

Private Const MAX_COMPUTERNAME_LENGTH = 15


Then place the following in the sub/function that you want to find the name of the computer in:

Dim sName As String
Dim lRetVal As Long
Dim lSize As Long

sName = String$(MAX_COMPUTERNAME_LENGTH + 1, ¯)

lSize = MAX_COMPUTERNAME_LENGTH + 1
lRetVal = GetComputerName(sName, lSize)

sName = Replace(sName, Chr(0), "")

Hi Senthil
The code fragment code sent in your mail is working absolutely fine on my machine. My machine is WinNT workstation having VB 6.0, VC 6.0 installed with service pack 3. So try on the m/c with above config.

Hi senthil
Earlier, I tried with the favourites but not with network option which was in your code and is failing on my machine, with SHGetPathFromIDList(lpIDList, sBuffer) function. Some other options are also failing with the same function like CSIDL_DRIVES, CSIDL_PRINTERS with the same function.
Rightnow don't know the reason. Will get back with reason.
bye
