Hi,

I try to obtain th OS version of a workstation on the network.

The code below don't work, an error occurs on the "nresult=" line :
"An unhandled exception of type 'System.NullReferenceException' occurred "

Any idea?

Thanx in advance
Public Declare Function NetServerGetInfo Lib "netapi32" ( _

ByVal ServerName As Byte, _

ByVal Level As Long, _

ByVal buffer As Long) As Long

im server As String

Dim srv() As Byte

Dim nresult As Long

Dim hbuffer As Long

Dim txtEncoder As New UTF8Encoding

server = "GLOBO"

hbuffer = 0

server = server & vbNullChar

srv = txtEncoder.GetBytes(server)

nresult = NetServerGetInfo(srv(0), 102, hbuffer)

Label1.Text = nresult
