TraceRoute Control

Properties Methods Events Config Settings Errors

The TraceRoute control allows you to trace the path that the IP packets take on the Internet.

Syntax

TraceRoute

Remarks

The component implements a standard IP TraceRoute as defined in RFC 1393.

To use the control, simply call the TraceTo method and set the Host parameter to the domain name or IP address of the host you want to trace the path to. This is identical to setting the RemoteHost property to the domain name or IP address. The control will start sending probe packets toward the host, and as it receives replies, it will fire Hop events giving information about the route. The same information is also provided in the Hops properties.

The ResolveNames property enables or disables DNS resolution of IP addresses received during the trace. If set to False, only IP addresses are provided. If set to True, the control will attempt to resolve the names of the hosts in the route. This may considerably increase the time it takes to complete the trace.

The HopTimeout property determines the maximum waiting time for a response in each hop of the trace, while the Timeout property defines the maximum waiting time for the whole trace. The HopLimit property specifies the maximum number of hops allowed for a trace.

HopLimit Property (TraceRoute Control)

This property includes the maximum number of hops to allow for a trace.

Syntax

traceroutecontrol.HopLimit[=integer]

Default Value

Remarks

This property is used to limit lengthy traces. A value of 0 indicates an unbounded trace.

String

HopHostName Property (TraceRoute Control)

This property contains the name of the host for a particular hop in the trace.

Syntax

traceroutecontrol.HopHostName(HopIndex)

Default Value

Remarks

This property contains the name of the host for a particular hop in the trace.

If ResolveNames is False, this property contains the IP address of the host instead.

The HopIndex parameter specifies the index of the item in the array. The size of the array is controlled by the HopCount property.

This property is read-only and not available at design time.

Data Type

String

HopTime Property (TraceRoute Control)

This property contains the amount of time taken by a particular hop in the trace.

Syntax

traceroutecontrol.HopTime(HopIndex)

Default Value

Remarks

This property contains the amount of time taken by a particular hop in the trace.

If a given hop times out, this value will be set to -1.

The HopIndex parameter specifies the index of the item in the array. The size of the array is controlled by the HopCount property.

This property is read-only and not available at design time.

Data Type

Integer

HopTimeout Property (TraceRoute Control)

This property includes the maximum amount of time to wait for an individual hop to complete.

Syntax

traceroutecontrol.HopTimeout[=integer]

Default Value

Remarks

The time value is in seconds. If 0, HopTimeout will be ignored, and only the Timeout for the whole trace will be taken into account.

Data Type

Integer

Idle Property (TraceRoute Control)

The current status of the control.

Syntax

traceroutecontrol.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 (TraceRoute Control)

The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

Syntax

traceroutecontrol.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

RemoteHost Property (TraceRoute Control)

This property includes the address of a host to trace to.

Syntax

traceroutecontrol.RemoteHost[=string]

Default Value

Remarks

Traces are initiated by setting RemoteHost to the name or address of the host to trace to.

This property must contain a valid Internet domain name or address or an error will be returned.

To interrupt a trace in progress, set RemoteHost to empty string.

Example. Perform a TraceRoute:

TraceRouteControl.TraceTo("myHost") is equivalent to TraceRouteControl.RemoteHost = "myHost"

Data Type

String

ResolveNames Property (TraceRoute Control)

This property determines whether the control resolves the host name for each host during the trace.

Syntax

traceroutecontrol.ResolveNames[=boolean]

Default Value

False

Remarks

This property determines whether the control resolves the name of host at each "hop" during the trace. The default value is False.

Note: If this property is set to True, the trace takes longer because of name resolution.

Data Type

Boolean

Timeout Property (TraceRoute Control)

The timeout for the control.

Syntax

traceroutecontrol.Timeout[=integer]

Default Value

Remarks

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If Timeout is set to a positive value, the control will wait for the operation to complete before returning control.

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

Config Method (TraceRoute Control)

Sets or retrieves a configuration setting.

Syntax

traceroutecontrol.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.

DoEvents Method (TraceRoute Control)

This method processes events from the internal message queue.

Syntax

traceroutecontrol.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 (TraceRoute Control)

This method interrupts the current method.

Syntax

traceroutecontrol.Interrupt

Remarks

If there is no method in progress, Interrupt simply returns, doing nothing.

Reset Method (TraceRoute Control)

This method will reset the control.

Syntax

traceroutecontrol.Reset

Remarks

This method will reset the control's properties to their default values.

ResolveRemoteHost Method (TraceRoute Control)

This method resolves the hostname in RemoteHost to an IP address.

Syntax

traceroutecontrol.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.

TraceTo Method (TraceRoute Control)

This method traces the route to a host.

Syntax

traceroutecontrol.TraceTo Host

Remarks

Traces are initiated by calling TraceTo, with the Host argument set to the name or address of the destination host to trace to. Host must contain a valid Internet domain name or address, or the control fails with an error. To interrupt a trace in progress, set RemoteHost to empty string. Calling this method is equivalent to setting the RemoteHost property to Host.

Example. Perform a TraceRoute:

TraceRouteControl.TraceTo("myHost") is equivalent to TraceRouteControl.RemoteHost = "myHost"

Error Event (TraceRoute Control)

Fired when information is available about errors during data delivery.

Syntax

Sub traceroutecontrol_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.

Hop Event (TraceRoute Control)

This event is fired for each hop in the trace to the RemoteHost .

Syntax

Sub traceroutecontrol_Hop(HopNumber As Integer, HostAddress As String, Duration As Integer)

Remarks

This event provides access to the information for each hop in the trace. The HopNumber parameter denotes which hop the trace is at. The HostAddress parameter is the IP address of the host for the hop identified by HopNumber. The Duration parameter shows the amount of time taken by the hop.

HopResolved Event (TraceRoute Control)

This event is fired when the name of a hop address is found.

Syntax

Sub traceroutecontrol_HopResolved(HopNumber As Integer, StatusCode As Integer, HopHostName As String)

Remarks

The StatusCode contains 0 if the address is resolved successfully, or an error code, in which case, HopHostName contains a textual description of the error.

Host name resolution is disabled by default. Set ResolveNames to True to enable it.

Config Settings (TraceRoute 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.

TraceRoute Config Settings

DelayHostResolution: Whether the hostname is resolved when RemoteHost is set.

This configuration setting specifies whether a hostname is resolved immediately when RemoteHost is set. If the control will resolve the hostname and the IP address will be present in the RemoteHost property. If , the hostname is not resolved until needed by the component when a method to connect or send data is called. If desired, ResolveRemoteHost may be called to manually resolve the value in RemoteHost at any time.

The default value is .

HopTimeoutInMilliseconds: The hop timeout is treated as milliseconds.

Setting HopTimeoutInMilliseconds to True causes the control to use the value in the HopTimeout property as milliseconds instead of seconds, which is the default.

TimeoutInMilliseconds: The timeout is treated as milliseconds.

Setting TimeoutInMilliseconds to True causes the control to use the value in the Timeout property as milliseconds instead of seconds, which is the default.

ICMP Config Settings

DelayHostResolution: Whether the hostname is resolved when RemoteHost is set.

The default value is .

DontFragment: Whether the DontFragment control flag is set.

When set to True, the DontFragment control flag in the IP header will be set.

The default value is False.

IcmpDllTimeout: The timeout for the control when using the icmp.dll.

The control will wait for the operation to complete before returning control. If IcmpDllTimeout expires, and the operation is not yet complete, the control fails with an error. IcmpDllTimeout must be set to a positive value.

The default value for IcmpDllTimeout is 60 seconds.

Note: This configuration setting is valid only when UseICMPDLL is set to True.

MaxMessageSize: The maximum length of the messages that can be received.

This setting specifies the maximum size of the datagrams that the control will accept without truncation.

MulticastTTL: The time to live (TTL) value for multicast ICMP packets sent by the component.

When sending multicast packets, the setting specifies the time-to-live (TTL) field. 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 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.

ReceiveAllMode: Enables a socket to receive all IPv4 or IPv6 packets on the network.

This setting specifies the ReceiveAll mode for the socket. The following modes are available:


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.

TimeoutInMilliseconds: The timeout is treated as milliseconds.

Setting TimeoutInMilliseconds to True causes the control to use the value in the IcmpDllTimeout configuration setting as milliseconds instead of seconds, which is the default.

Note: This setting is valid only when UseICMPDLL is set to True.

UseConnection: Determines whether to use a connected socket.

UseConnection specifies whether or not the control should use a connected socket. The connection is defined as an association in between the local address/port and the remote address/port. As such, this is not a connection in the traditional Transmission Control Protocol (TCP) sense. It means only that the control will send and receive data to and from the specified destination.

The default value for this setting is False.

UseICMPDLL: Use the icmp.dll included on Windows Systems.

Setting UseICMPDLL to True causes the control to use the icmp.dll on Windows 9x or on later machines. This sometimes enables access to raw sockets when permissions for standard operations are prohibited.

UseIPHLPDLL: Use the iphlpapi.dll included on Windows Systems.

Setting UseIPHLPDLL to True causes the control to use the iphlpapi.dll on Windows XP or on later machines. This sometimes enables access to raw sockets when permissions for standard operations are prohibited.

Note: If both this and UseICMPDLL are enabled, the iphlpapi.dll will take precedence.

UseIPv6: Whether to use IPv6.

When set to 0 (default), the control will use IPv4 exclusively. When set to 1, the control will use IPv6 exclusively. To instruct the control to prefer IPv6 addresses, but use IPv4 if IPv6 is not supported on the system, this setting should be set to 2. The default value is 0. Possible values are as follows:


0	IPv4 only
1	IPv6 only
2	IPv6 with IPv4 fallback

Socket Config Settings

AbsoluteTimeout: Determines whether timeouts are inactivity timeouts or absolute timeouts.

If AbsoluteTimeout is set to True, any method that does not complete within Timeout seconds will be aborted. By default, AbsoluteTimeout is False, and the timeout is an inactivity timeout.

Note: This option is not valid for User Datagram Protocol (UDP) ports.

FirewallData: Used to send extra data to the firewall.

When the firewall is a tunneling proxy, use this property to send custom (additional) headers to the firewall (e.g., headers for custom authentication schemes).

InBufferSize: The size in bytes of the incoming queue of the socket.

This is the size of an internal queue in the Transmission Control Protocol (TCP)/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. In some cases, increasing the value of the InBufferSize setting can provide significant improvements in performance.

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.

OutBufferSize: The size in bytes of the outgoing queue of the socket.

This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be sending. In some cases, increasing the value of the OutBufferSize setting can provide significant improvements in performance.

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.
