Error Starting Program
[!] The PUREBASIC8491641.EXE file is
linked to missing export NETAPI32.DLL:NetWkstaGetInfo.

Maybe because I use Windows98 original?

Yep, Win NT/2k/XP only, sorry.

Here is another example (Fred's code I think) ; it could work with Win98 ?

Code: Select all

Structure HOSTENT
  h_name.l
  h_aliases.l
  h_addrtype.w
  h_length.w
  h_addr_list.l
EndStructure


If InitNetwork()


  Hostname$ = Space(255)
  gethostname_(Hostname$,255)

  Debug "Hostname: "+Hostname$

  pHostinfo = gethostbyname_(Hostname$)

  If pHostinfo = 0 

    Debug "Unable to resolve domain name."

  Else

    CopyMemory (pHostinfo, hostinfo.HOSTENT, SizeOf(HOSTENT))


    If hostinfo\h_addrtype <> #AF_INET

      Debug "A non-IP address was returned."

    Else

      While PeekL(hostinfo\h_addr_list+AdressNumber*4)

        ipAddress = PeekL(hostinfo\h_addr_list+AdressNumber*4)
        Debug StrU(PeekB(ipAddress),0)+"."+StrU(PeekB(ipAddress+1),0)+"."+StrU(PeekB(ipAddress+2),0)+"."+StrU(PeekB(ipAddress+3),0)
        AdressNumber+1

      Wend

          

    EndIf

  EndIf

Else

  Debug "Network can't be initialized"

EndIf

Should work, the commands used all work starting from Win95
