Bonjour,

J'ai un probleme lorsque j'essaie de recuperer l'adresse
mac d'un ordinateur qui est sous NT cela me renvoie
toujours la valeur suivant 0.0.0.0.0.0(sur toutes les
autres versions de windows ca fonctionne).
Si quelqu'un peut m'aider.
A moins que je sois obliger de la recuperer sosu dos avec
la commande arp et ensuite placer la valeur dan sun
fichier et ensuite j'irai chcer cette valeur a partir de
mon prog vb ( je ne trouve pas cette idee tres bonne!)

Merci beaucoup

Voila le code que j'utilise:

Option Explicit

Private Const NCBASTAT = &H33

Salut !

J'ai trouvé sur "microsoft.fr" en tapant le mot clé "mac" dans la zone de recherche de la page d'accueil un meilleur code pour récupérer la mac adresse. Ce prog marche sur toutes les versions de windows. Il a été testé sous VB6.

Le voici :

'A mettre dans un module
Public Const NCBASTAT As Long = &H33
Public Const NCBNAMSZ As Long = 16
Public Const NCBRESET As Long = &H32

Public Type NET_CONTROL_BLOCK
ncb_command As Byte
ncb_retcode As Byte
ncb_lsn As Byte
ncb_num As Byte
ncb_buffer As Long
ncb_length As Integer
ncb_callname As String * NCBNAMSZ
ncb_name As String * NCBNAMSZ
ncb_rto As Byte
ncb_sto As Byte
ncb_post As Long
ncb_lana_num As Byte
ncb_cmd_cplt As Byte
ncb_reserve(9) As Byte
ncb_event As Long
End Type

Public Type ADAPTER_STATUS
adapter_address(5) As Byte
rev_major As Byte
reserved0 As Byte
adapter_type As Byte
rev_minor As Byte
duration As Integer
frmr_recv As Integer
frmr_xmit As Integer
iframe_recv_err As Integer
xmit_aborts As Integer
xmit_success As Long
recv_success As Long
iframe_xmit_err As Integer
recv_buff_unavail As Integer
t1_timeouts As Integer
ti_timeouts As Integer
Reserved1 As Long
free_ncbs As Integer
max_cfg_ncbs As Integer
max_ncbs As Integer
xmit_buf_unavail As Integer
max_dgram_size As Integer
pending_sess As Integer
max_cfg_sess As Integer
max_sess As Integer
max_sess_pkt_size As Integer
name_count As Integer
End Type

Public Type NAME_BUFFER
name As String * NCBNAMSZ
name_num As Integer
name_flags As Integer
End Type

Public Type ASTAT
adapt As ADAPTER_STATUS
NameBuff(30) As NAME_BUFFER
End Type

Public Declare Function Netbios Lib "netapi32.dll" (pncb As NET_CONTROL_BLOCK) As Byte

Public Function MACAddress() As String
Dim macAdr As String
Dim ncb As NET_CONTROL_BLOCK
Dim adapter As ASTAT

ncb.ncb_command = NCBRESET
Call Netbios(ncb)

ncb.ncb_command = NCBASTAT
ncb.ncb_lana_num = 0
ncb.ncb_callname = "* "
ncb.ncb_buffer = VarPtr(adapter)
ncb.ncb_length = Len(adapter)

Call Netbios(ncb) 'renvoie entre autre la mac adresse dans une structure
For i = 0 To 5
macAdr = macAdr & Format$(Hex(adapter.adapt.adapter_address(i)), "00") & " "
Next i

macAdr = Trim(macAdr) 'Enlève les espces à droite et à gauche de la chaîne
MACAddress = macAdr

End Function

'prog principal
Private Sub Form_load()
MsgBox MACAddress
End Sub

j'espère que je t'aurais aider.
