摘要:[VB6] 使用 ICMP 來 ping

法一:利用WIN32 API
http://support.microsoft.com/kb/300197
這是microsoft的官網裡面有教你如何使用ICMP來ping一個位置,其主要是利用ICMP通訊協助定API寫的,其中包含了不少API的宣告程式又臭又長,請看以下範

法二:利用WMI(Windows Management Instrumentation)
可愛又好用的WMI又來了,上述的功能,當然也可以利用WMI Win32_PingStatus達
成其目的,MSDN裡面有詳細的說明哩!ICMP Win32 API Ping.rarhttp://msdn.microsoft.com/en-us/library/aa394350.aspx

class Win32_PingStatus
{
  string Address;
  uint32 BufferSize = 32;
  boolean NoFragmentation = FALSE;
  uint32 PrimaryAddressResolutionStatus;
  string ProtocolAddress = "";
  string ProtocolAddressResolved = "";
  uint32 RecordRoute = 0;
  boolean ReplyInconsistency;
  uint32 ReplySize;
  boolean ResolveAddressNames = FALSE;
  uint32 ResponseTime;
  uint32 ResponseTimeToLive;
  string RouteRecord[];
  string RouteRecordResolved[];
  String SourceRoute = "";
  uint32 SourceRouteType = 0;
  uint32 StatusCode;
  uint32 Timeout = 1000;
  uint32 TimeStampRecord[];
  string TimeStampRecordAddress[];
  string TimeStampRecordAddressResolved[];
  uint32 TimeStampRoute = 0;
  uint32 TimeToLive = 80;
  uint32 TypeofService = 0;
};

我個人覺得還是WMI好用多了,讚!
不過懶的寫範例,直接上網google一下,便有一堆資料了,
http://www.enterpriseitplanet.com/networking/features/article.php/1571771


以下程式碼用於vbs,要改一下才能在vb6上面run

Dim sHost  'name of Windows XP computer from which the

PING command will be initiated
Dim sTarget  'name or IP address of remote computer to which

connectivity will be tested
Dim cPingResults 'collection of instances of Win32_PingStatus

class
Dim oPingResult  'single instance of Win32_PingStatus class

sHost  = "SWYNKPC-XP001"
sTarget  = "192.168.12.14"

Set cPingResults = GetObject("winmgmts:

{impersonationLevel=impersonate}//" & _
  sHost & "/root/cimv2"). ExecQuery("SELECT * FROM

Win32_PingStatus " & _
  "WHERE Address = '" + sTarget + "'")

For Each oPingResult In cPingResults
 If oPingResult.StatusCode = 0 Then
  If LCase(sTarget) = oPingResult.ProtocolAddress Then
   WScript.Echo sTarget & " is responding"
  Else
   WScript.Echo sTarget & "(" &

oPingResult.ProtocolAddress & ") is responding"
  End If
  Wscript.Echo "Bytes = " & vbTab &

oPingResult.BufferSize
  Wscript.Echo "Time (ms) = " & vbTab &

oPingResult.ResponseTime
  Wscript.Echo "TTL (s) = " & vbTab &

oPingResult.ResponseTimeToLive
 Else
  WScript.Echo sTarget & " is not responding"
  WScript.Echo "Status code is " & oPingResult.StatusCode
 End If
Next
