Sample Code:
Const MAX_PREFERRED_LENGTH As Integer = -1
Dim dwIndex, dwStatus, dwReadEntries, dwTotalEntries As Integer
Dim pCurrent As FILE_INFO_3
Dim iPtr, pBuffer As IntPtr
dwStatus = NetFileEnum(TextBox1.Text, Nothing, Nothing, 3, pBuffer, MAX_PREFERRED_LENGTH, dwReadEntries, dwTotalEntries, Nothing)
if dwStatus = 0 then
For dwIndex = 0 To dwReadEntries - 1
iPtr = New IntPtr(pBuffer.ToInt32 + (dwIndex * Len(pCurrent)))
pCurrent = CType(Marshal.PtrToStructure(iPtr, GetType(FILE_INFO_3)), FILE_INFO_3)
'Debug.WriteLine("dwIndex=" & dwIndex)
'Debug.WriteLine(" id: " & pCurrent.fi3_id)
'Debug.WriteLine(" num_locks: " & pCurrent.fi3_num_locks)
'Debug.WriteLine(" pathname: " & pCurrent.fi3_pathname)
'Debug.WriteLine(" permission: " & pCurrent.fi3_permission)
'Debug.WriteLine(" username: " & pCurrent.fi3_username)
