TCP, UDP, Daemon, DNS, Ping and RAS controls for Internet application development.

Ping ActiveX Control

Use the Ping control to easily send and receive ICMP echo (Ping) messages. Dynamically discovers if a host is reachable. Features include:

  • Determine if any host is online and reachable.
  • Simple interface makes the Ping control easy-to-use.
  • Ping a host using blocking or non-blocking techniques.
  • Specify any amount of data to send along with the Ping packet.
  • Assign an ID to the Ping packet.

Ping Use the Ping Control to determine if a host is reachable.
Public Properties
Data Optional data that is sent and returned with each ping request.
Delay Time between sending the ping request and receiving the response (round-trip time in milliseconds).
Id Sets the ping request ID included with the request.
Timeout Controls the blocking behavior of methods that can be used in blocking and non-blocking ways.
Public Methods
Abort Abort any blocking method and release all system resources.
About Show the About Box.
Ping Determine if a host is reachable.
Error Fires when an error condition occurs.
Response Fires after the Id, Delay, and Data properties are updated with the contents of a ping response.

Code Example

How easy is the Ping ActiveX component to use? Check out the following Ping VB example below, which demonstrates getting an IP address for a domain name.

On Error GoTo OnError ' use intrinsic error handling

   Dim Count As Integer
   Dim Delay As Integer
   Ping1.Timeout = 10000 'give it 10 seconds to complete
   Delay = 0

   ' Ping a host 3 times.
   For Count = 1 To 3
      Ping1.Ping "www.dart.com" 
      Delay = Delay + Ping1.Delay
   Next Count

   ' take the average time
   Delay = Delay / Count
   MsgBox "Server is reachable, average delay " & Delay & " ms"

   Exit Sub

OnError: ' Any error jumps here
   Debug.Print "ERROR #" + CStr(Err.Number) + ": " + Err.Description
