Ping Control
Properties Methods Events Config Settings Errors
The PING control encapsulates Internet Control Message Protocol (ICMP) ECHO functionality, which is used to check whether there is a communications link between two computers.
Syntax
Ping
Remarks
When the PingHost method is called with the Host parameter, or if RemoteHost is assigned an IP address or domain name, the control sends an ICMP ECHO packet to the remote host. The ResponseTime and ResponseSource properties are updated with the time of the roundtrip to the remote host and the address of the host actually sending the response.
The control operates synchronously by default (i.e., waits for a response before returning control to the caller); however, the control may also operate asynchronously (i.e., returns control immediately) by setting Timeout to 0. Please refer to the Timeout property for more information.

Active Property (Ping Control)
This property indicates whether the control is active.
Syntax
pingcontrol.Active
Default Value
False
Remarks
This property indicates whether the control is currently active and can send or receive data. Use the Activate and Deactivate methods to control whether the control is active.
The PingHost method will automatically change the value of this property to True.
This property is read-only and not available at design time.
Data Type
Boolean
Idle Property (Ping Control)
The current status of the control.
Syntax
pingcontrol.Idle
Default Value
True
Remarks
This property will be False if the component is currently busy (communicating or waiting for an answer), and True at all other times.
This property is read-only.
Data Type
Boolean
LocalHost Property (Ping Control)
The name of the local host or user-assigned IP interface through which connections are initiated or accepted.
Syntax
pingcontrol.LocalHost[=string]
Default Value
""
Remarks
This property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.
In multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the control initiate connections (or accept in the case of server controls) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used.
If the control is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).
Note: LocalHost is not persistent. You must always set it in code, and never in the property window.
Data Type
String
PacketSize Property (Ping Control)
This property includes the size of the packet to send as the ping request.
Syntax
pingcontrol.PacketSize[=integer]
Default Value
64
Remarks
This property allows you to control the size of the data packet sent in the PingHost method. The default packet size is 64 bytes, with a minimum of 8 bytes (4 bytes of the ICMP header plus the ECHO identifier). The maximum value is 65520.
Data Type
Integer
RemoteHost Property (Ping Control)
This property includes the address of the RemoteHost. Domain names are resolved to IP addresses.
Syntax
pingcontrol.RemoteHost[=string]
Default Value
""
Remarks
This property specifies the IP address (IP number in dotted internet format) or the domain name of the remote host.
If this property is set to 255.255.255.255, the control broadcasts data on the local subnet.
If this property is set to a domain name, a DNS request is initiated. Upon successful termination of the request, the property is set to the corresponding address. If the search is not successful, the control fails with an error.
If UseConnection is True, this property must be set before the control is activated (Active is set to True).
Data Type
String
RequestId Property (Ping Control)
This property includes a unique identifier for outgoing packets.
Syntax
pingcontrol.RequestId
Default Value
0
Remarks
This property contains a unique identifier for outgoing packets. This property is useful during asynchronous ping operations. The RequestId parameter of the Response event is used to match requests with responses.
The identifier of the outgoing ping packet is provided in this property after the PingHost method returns.
This property is read-only and not available at design time.
Data Type
Integer
ResponseSource Property (Ping Control)
This property includes the source of the last PING response.
Syntax
pingcontrol.ResponseSource
Default Value
""
Remarks
This property contains the address of the host responding to the PING (ICMP ECHO) request. This may or may not be the host used in PingHost.
This property is read-only.
Data Type
String
ResponseStatus Property (Ping Control)
This property includes the status of the last PING response.
Syntax
pingcontrol.ResponseStatus
Default Value
""
Remarks
This property contains the status of the last response. After PingHost has returned, this property will be populated with the status of the response. For responses without error, the value will be OK. In the case of an error, the value will hold a description of the error, such as Network Unreachable or Host Unreachable.
This property is read-only.
Data Type
String
ResponseTime Property (Ping Control)
This property includes the time elapsed between sending the original packet and the remote host reply.
Syntax
pingcontrol.ResponseTime
Default Value
0
Remarks
This property contains the time elapsed between sending the original packet and the remote host reply. The time value is expressed in milliseconds. The lowest resolution available depends on the resolution of the clock on the host system (normally between 10 ms and 20 ms).
This property is read-only.
Data Type
Integer
Timeout Property (Ping Control)
This property includes the timeout for the control.
Syntax
pingcontrol.Timeout[=integer]
Default Value
60
Remarks
If the Timeout property is set to 0, all operations return immediately, potentially failing with a WOULDBLOCK error if data cannot be sent immediately.
If Timeout is set to a positive value, data is sent in a blocking manner and the control will wait for the operation to complete before returning control. The control will handle any potential WOULDBLOCK errors internally and automatically retry the operation for a maximum of Timeout seconds.
The control will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not freeze and remains responsive.
If Timeout expires, and the operation is not yet complete, the control fails with an error.
Note: By default, all timeouts are inactivity timeouts, that is, the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.
The default value for the Timeout property is 60 seconds.
Data Type
Integer
TimeToLive Property (Ping Control)
This property includes the time-to-live (TTL) value for the ICMP packets sent by the control.
Syntax
pingcontrol.TimeToLive[=integer]
Default Value
0
Remarks
This method contains the time-to-live (TTL) value for the ICMP packets sent by the control. The TTL field of the ICMP packet is a counter limiting the lifetime of a packet.
Each router (or other module) that handles a packet decrements the TTL field by one or more if it holds the packet for more than one second. Thus, the TTL value is effectively a hop count limit on how far a datagram can propagate through the internet. When the TTL value is reduced to zero (or less), the packet is discarded.
If the value of the property is set to zero, then the default TTL value of the underlying Transmission Control Protocol (TCP)/IP subsystem will be used.
This property is not available at design time.
Data Type
Integer
TypeOfService Property (Ping Control)
This property includes the type of ICMP message sent as a ping request.
Syntax
pingcontrol.TypeOfService[=integer]
Default Value
8
Remarks
This property contains the type of the ICMP message sent as a ping request. The default value is 8 (ECHO REQUEST).
This property is not available at design time.
Data Type
Integer
Activate Method (Ping Control)
This method enables sending and receiving data.
Syntax
pingcontrol.Activate
Remarks
This method enables sending and receiving of data.
Note: Calling the PingHost method will automatically activate the control.
Config Method (Ping Control)
Sets or retrieves a configuration setting.
Syntax
pingcontrol.Config ConfigurationString
Remarks
Config is a generic method available in every control. It is used to set and retrieve configuration settings for the control.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the control, access to these internal properties is provided through the Config method.
To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).
To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.
Deactivate Method (Ping Control)
This method disables sending and receiving data.
Syntax
pingcontrol.Deactivate
Remarks
This method disables sending and receiving data.
DoEvents Method (Ping Control)
This method processes events from the internal message queue.
Syntax
pingcontrol.DoEvents
Remarks
When DoEvents is called, the control processes any available events. If no events are available, it waits for a preset period of time, and then returns.
Interrupt Method (Ping Control)
This method interrupts the current method.
Syntax
pingcontrol.Interrupt
Remarks
If there is no method in progress, Interrupt simply returns, doing nothing.
PingHost Method (Ping Control)
This method pings a host.
Syntax
pingcontrol.PingHost Host
Remarks
This method will ping a host. A valid internet domain name or address must be specified in Host, or an error will be returned.
A PING request (ICMP ECHO) is sent to the Host.
Example. Ping a Host:
PingControl.PingHost("MyHostName")
ResponseTime = PingControl.ResponseTime
Reset Method (Ping Control)
This method will reset the control.
Syntax
pingcontrol.Reset
Remarks
This method will reset the control's properties to their default values.
ResolveRemoteHost Method (Ping Control)
This method resolves the hostname in RemoteHost to an IP address.
Syntax
pingcontrol.ResolveRemoteHost
Remarks
This method resolves the hostname specified by RemoteHost to an IP address. The resolved value is available in the RemoteHost property after this method returns.
In most cases, calling this method is not necessary; the control will resolve the hostname automatically when needed. If DelayHostResolution is , this method may be called to manually resolve RemoteHost, if desired.
WakeOnLAN Method (Ping Control)
This method sends a Wake-On-LAN packet.
Syntax
pingcontrol.WakeOnLAN RemoteHost, MACAddress
Remarks
When this method is called, a Wake-On-LAN packet is sent to RemoteHost (which may also be a broadcast address). This has the effect of powering on the machine (if such functionality is supported by the network card on the remote machine).
The physical address of the remote host must be supplied in the MACAddress parameter.
Error Event (Ping Control)
Fired when information is available about errors during data delivery.
Syntax
Sub pingcontrol_Error(ErrorCode As Integer, Description As String)
Remarks
The Error event is fired in case of exceptional conditions during message processing. Normally the control fails with an error.
The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.
Response Event (Ping Control)
This event is fired when a response packet is received.
Syntax
Sub pingcontrol_Response(RequestId As Integer, ResponseSource As String, ResponseStatus As String, ResponseTime As Integer)
Remarks
The RequestId parameter is used along with the RequestId property to match requests with responses.
ResponseStatus is set to OK for normal operation, or it contains an error string, such as Network unreachable or Host unreachable.
Config Settings (Ping Control)
The control accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the control, access to these internal properties is provided through the Config method.Ping Config Settings
The default value is .
ICMP Config Settings
The default value is .
The default value is False.
The default value for IcmpDllTimeout is 60 seconds.
Note: This configuration setting is valid only when UseICMPDLL is set to True.
Each router (or other module) that handles a packet decrements the TTL field by one or more if it holds the packet for more than one second. Thus, the TTL is effectively a hop count limit on how far a datagram can propagate through the internet. When the TTL is reduced to zero (or less), the packet is discarded.
By default, the default TTL value of the underlying Transmission Control Protocol (TCP)/IP subsystem will be used.
| Value | Description |
| -1 (default) | The socket option is left unspecified. |
| 0 | Do not receive all network traffic. |
| 1 | Receive all network traffic. This enables the promiscuous mode on the network interface card (NIC). On a LAN segment with a network hub, a NIC that supports the promiscuous mode will capture all IPv4 or IPv6 traffic on the LAN, including traffic between other computers on the same LAN segment. |
| 2 | Receive only socket-level network traffic (this feature may not be implemented by your Windows installation). |
| 3 | Receive only IP-level network traffic. This option does not enable the promiscuous mode on the NIC. This option affects packet processing only at the IP level. The NIC still receives only those packets directed to its configured unicast and multicast addresses. A socket with this option enabled, however, not only will receive packets directed to specific IP addresses, but also will receive all the IPv4 or IPv6 packets the NIC receives. |
Note: This setting is valid only when UseICMPDLL is set to True.
The default value for this setting is False.
Note: If both this and UseICMPDLL are enabled, the iphlpapi.dll will take precedence.
| 0 | IPv4 only |
| 1 | IPv6 only |
| 2 | IPv6 with IPv4 fallback |
Socket Config Settings
Note: This option is not valid for User Datagram Protocol (UDP) ports.
Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the control is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.
Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the control is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.
