Just started looking at this bit of code - think it holds the key. Since the SendData method takes a string, then this routine is somehow constructing a string containing nulls ?

Whats with the sixteen times mac address thingy ? Is that part of the trick or just something to do with WOL ?

code:
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
'     Function:          CreatePacket
'     Params:               array of bytes representing Mac address of target
'     Return:               String of data representing Magic Packet data
'     Notes:               Magic Packet is six bytes of chr(&HFF) folowed by 16 copies of the target adapter's
'                         Mac address
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
Private Function CreatePacket(arMacAddr)
     Dim Item
     Dim strTemp
     Dim strData

     For Each Item in arMacAddr
          Item = "&H" & Item
          strTemp = strTemp & chr(Item)
     Next
     For i = 1 to 16
          strData = strData & strTemp
     Next
     CreatePacket = String(6, &HFF) & strData
End Function
