SQL Servers
I use the following code to display all the SQL servers on the network:
VB Code:
Option Explicit
Private Declare Function lstrlenW Lib "kernel32" (ByVal lpString As Long) As Long
Private Declare Function NetServerEnum Lib "netapi32" ( _
strServername As Any, _
ByVal level As Long, _
bufptr As Long, _
ByVal prefmaxlen As Long, _
entriesread As Long, _
totalentries As Long, _
ByVal servertype As Long, _
strDomain As Any, _
resumehandle As Long) As Long
Private Declare Function NetApiBufferFree Lib "Netapi32.dll" _
(ByVal lpBuffer As Long) As Long
Private Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" _
(Destination As Any, Source As Any, ByVal Length As Long)
Private Const SV_TYPE_SERVER As Long = &H2
Private Const SV_TYPE_SQLSERVER As Long = &H4
Private Type SV_100
platform As Long
Name As Long
End Type
Public DEBUGMODE As Boolean
Public Function GetSQLServers(DomainName As String) As String()
Dim l As Long
Dim entriesread As Long
Dim totalentries As Long
Dim hREsume As Long
Dim bufptr As Long
Dim level As Long
Dim prefmaxlen As Long
Dim lType As Long
Dim Domain() As Byte
Dim i As Long
Dim sv100 As SV_100
Dim Servers() As String
level = 100
prefmaxlen = -1
lType = SV_TYPE_SQLSERVER
Domain = DomainName & vbNullChar
l = NetServerEnum(ByVal 0&, _
level, _
bufptr, _
prefmaxlen, _
entriesread, _
totalentries, _
lType, _
Domain(0), _
hREsume)
If l = 0 Or l = 234& Then
ReDim Servers(entriesread - 1)
For i = 0 To entriesread - 1
CopyMemory sv100, ByVal bufptr, Len(sv100)
Servers(i) = Pointer2stringw(sv100.Name)
bufptr = bufptr + Len(sv100)
Next i
Else
ReDim Servers(0)
Servers(0) = "N/A"
End If
NetApiBufferFree bufptr
GetSQLServers = Servers
End Function
Private Function Pointer2stringw(ByVal l As Long) As String
Dim buffer() As Byte
Dim nLen As Long
'
nLen = lstrlenW(l) * 2
If nLen Then
ReDim buffer(0 To (nLen - 1)) As Byte
CopyMemory buffer(0), ByVal l, nLen
Pointer2stringw = buffer
End If
End Function
However, if I stop running the server on my machine and then resume it again, it won't show up again. Any ideas why?

Nervermind,
It seems that it needs few minutes before finding it again. Weird.
