TFTPClient Component

Properties   Methods   Events   Config Settings   Errors  

The TFTPClient component is used to exchange files with TFTP servers via the TFTP protocol defined in RFC 783.

Syntax

TipwTFTPClient

Remarks

To use the component, first specify the TFTPServer, then a LocalFile and a RemoteFile, and then call GetFile or PutFile. The Transfer event shows the progress of the transfer.

Potential transmission errors and packet loss are managed by the Timeout property which controls the maximum time to wait for a response from the server, and the MaxRetransmits property which specifies how many times to resend a failed packet before giving up.

Idle Property (TFTPClient Component)

The current status of the component.

Syntax

__property bool Idle = { read=FIdle };

Default Value

True

Remarks

Idle will be False if the component is currently busy (communicating and/or waiting for an answer), and True at all other times.

This property is read-only.

Data Type

Boolean

LocalFile Property (TFTPClient Component)

The file on the local host to transfer the data to/from.

Syntax

__property String LocalFile = { read=FLocalFile, write=FSetLocalFile };

Default Value

""

Remarks

If GetFile is called, and LocalFile already exists, it is overwritten. If PutFile is called, LocalFile must point to a valid file, or an error will be returned.

Data Type

String

LocalHost Property (TFTPClient Component)

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

Syntax

__property String LocalHost = { read=FLocalHost, write=FSetLocalHost };

Default Value

""

Remarks

The LocalHost 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 multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the component initiate connections (or accept in the case of server components) only through that interface.

If the component 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 multi-homed 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

MaxRetransmits Property (TFTPClient Component)

The number of times to retry sending a failed packet before disconnecting.

Syntax

__property int MaxRetransmits = { read=FMaxRetransmits, write=FSetMaxRetransmits };

Default Value

3

Remarks

This property allows you to specify the number of times that you would like to try re-sending the last data packet if the original packet fails.

The RetransmitTimeout determines the wait time (in seconds) between successive retransmissions.

The default value for the MaxRetransmits property is 3.

Data Type

Integer

RemoteFile Property (TFTPClient Component)

The file on the remote host.

Syntax

__property String RemoteFile = { read=FRemoteFile, write=FSetRemoteFile };

Default Value

""

Remarks

When the GetFile is called, this must be a valid file on the TFTPServer.

Data Type

String

RetransmitTimeout Property (TFTPClient Component)

Maximum time in seconds to wait for a reply packet from the server before retransmitting the last packet.

Syntax

__property int RetransmitTimeout = { read=FRetransmitTimeout, write=FSetRetransmitTimeout };

Default Value

5

Remarks

Please refer to the MaxRetransmits property for the number of retransmit efforts before an error is returned.

The default value for the RetransmitTimeout is 5 seconds.

Data Type

Integer

TFTPPort Property (TFTPClient Component)

The UDP port where the remote TFTP server is listening.

Syntax

__property int TFTPPort = { read=FTFTPPort, write=FSetTFTPPort };

Default Value

69

Remarks

The TFTPPort is the UDP port on the TFTPServer to send TFTP requests to.

This property is not available at design time.

Data Type

Integer

TFTPServer Property (TFTPClient Component)

The address of the TFTP server to exchange files with.

Syntax

__property String TFTPServer = { read=FTFTPServer, write=FSetTFTPServer };

Default Value

""

Remarks

To be able to transfer file via TFTP, the remote host must be running TFTP services on port TFTPPort (default 69).

Example (Get a File)

TFTPControl.TFTPServer = "MyServer" TFTPControl.LocalFile = "C:\filename.txt" TFTPControl.RemoteFile = "/remotefile.txt" TFTPControl.GetFile()

Data Type

String

Timeout Property (TFTPClient Component)

A timeout for the component.

Syntax

__property int Timeout = { read=FTimeout, write=FSetTimeout };

Default Value

60

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 component will wait for the operation to complete before returning control.

The component 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 component raises an exception.

Please note that by default, all timeouts are inactivity timeouts, i.e. 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 (TFTPClient Component)

Sets or retrieves a configuration setting.

Syntax

String __fastcall Config(String ConfigurationString);

Remarks

Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, 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 (TFTPClient Component)

Processes events from the internal message queue.

Syntax

void __fastcall DoEvents();

Remarks

When DoEvents is called, the component processes any available events. If no events are available, it waits for a preset period of time, and then returns.

GetFile Method (TFTPClient Component)

Download a RemoteFile from the TFTP server.

Syntax

void __fastcall GetFile();

Remarks

The remote file specified by RemoteFile is downloaded to the local file specified by LocalFile, or it is retrieved through the Transfer event, if the LocalFile property is "" (empty string).

Example (Get a File)

TFTPControl.TFTPServer = "MyServer" TFTPControl.LocalFile = "C:\filename.txt" TFTPControl.RemoteFile = "/remotefile.txt" TFTPControl.GetFile()

Interrupt Method (TFTPClient Component)

Interrupt the current method.

Syntax

void __fastcall Interrupt();

Remarks

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

PutFile Method (TFTPClient Component)

Upload a file specified by LocalFile to the TFTP server.

Syntax

void __fastcall PutFile();

Remarks

The local file specified by LocalFile is uploaded to the remote file specified by RemoteFile.

Example (Put a File)

TFTPControl.TFTPServer = "MyServer" TFTPControl.LocalFile = "C:\filename.txt" TFTPControl.RemoteFile = "/remotefile.txt" TFTPControl.PutFile()

Reset Method (TFTPClient Component)

Reset the component.

Syntax

void __fastcall Reset();

Remarks

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

EndTransfer Event (TFTPClient Component)

This event is fired when a file finishes downloading or uploading.

Syntax

typedef struct {
  int Direction;
} TipwTFTPClientEndTransferEventParams;
typedef void __fastcall (__closure *TipwTFTPClientEndTransferEvent)(System::TObject* Sender, TipwTFTPClientEndTransferEventParams *e);
__property TipwTFTPClientEndTransferEvent OnEndTransfer = { read=FOnEndTransfer, write=FOnEndTransfer };

Remarks

The EndTransfer event fires when a Data Interface connection is closed. This occurs when the file finishes transferring or a directory listing is finished.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

Error Event (TFTPClient Component)

Information about errors during data delivery.

Syntax

typedef struct {
  int ErrorCode;
  String Description;
} TipwTFTPClientErrorEventParams;
typedef void __fastcall (__closure *TipwTFTPClientErrorEvent)(System::TObject* Sender, TipwTFTPClientErrorEventParams *e);
__property TipwTFTPClientErrorEvent OnError = { read=FOnError, write=FOnError };

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the component raises an exception.

ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

StartTransfer Event (TFTPClient Component)

This event fires when a file starts downloading or uploading.

Syntax

typedef struct {
  int Direction;
} TipwTFTPClientStartTransferEventParams;
typedef void __fastcall (__closure *TipwTFTPClientStartTransferEvent)(System::TObject* Sender, TipwTFTPClientStartTransferEventParams *e);
__property TipwTFTPClientStartTransferEvent OnStartTransfer = { read=FOnStartTransfer, write=FOnStartTransfer };

Remarks

The StartTransfer event fires when a Data Interface connection is created. This is when the file starts transferring or a directory listing is started.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

Transfer Event (TFTPClient Component)

This event is fired during the file download or upload.

Syntax

typedef struct {
  int Direction;
  __int64 BytesTransferred;
  int PercentDone;
  String Text;
  DynamicArray<Byte> TextB;
} TipwTFTPClientTransferEventParams;
typedef void __fastcall (__closure *TipwTFTPClientTransferEvent)(System::TObject* Sender, TipwTFTPClientTransferEventParams *e);
__property TipwTFTPClientTransferEvent OnTransfer = { read=FOnTransfer, write=FOnTransfer };

Remarks

One or more Transfer events are fired during file transfer. The BytesTransferred parameter shows the number of bytes transferred since the beginning of the transfer.

Text contains the portion of the file data being delivered.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.

Note: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.

Config Settings (TFTPClient Component)

The component 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 component, access to these internal properties is provided through the Config method.

TFTPClient Config Settings

BlockSize:   Determines the block size that will be used when transferring a file. Set this to the number of bytes the block should be. This uses the blocksize option as defined in RFC 2348. The default is 512.

TransferMode:   Determines the transfer mode that will be used when transferring a file. Available modes: Value Description 0 (default) Binary (Octet) 1 Ascii (Netascii)

UDP Config Settings

CaptureIPPacketInfo:   Used to capture the packet information. If this is set to true, the component will capture the IP packet information. The default value for this setting is False. Note: This setting is only available in Windows.

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

DestinationAddress:   Used to get the destination address from the packet information. If CaptureIPPacketInfo is set to true, then this will be populated with the packet's destination address when a packet is received. This information will be accessible in the DataIn event. Note: This setting is only available in Windows.

DontFragment:   Used to set the Don't Fragment flag of outgoing packets. When set to True, packets sent by the component will have the Don't Fragment flag set. The default value is False.

LocalHost:   The name of the local host through which connections are initiated or accepted. The LocalHost setting 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 multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the component initiate connections (or accept in the case of server components) only through that interface. If the component is connected, the LocalHost setting 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 multi-homed hosts (machines with more than one IP interface).

LocalPort:   The port in the local host where the component binds. This must be set before a connection is attempted. It instructs the component to bind to a specific port (or communication endpoint) in the local machine. Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established. LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error. This; setting is useful when trying to connect to services that require a trusted port in the client side. An example is the remote shell (rsh) service in UNIX systems.

MaxPacketSize:   The maximum length of the packets that can be received. This setting specifies the maximum size of the datagrams that the component will accept without truncation.

QOSDSCPValue:   Used to specify an arbitrary QOS/DSCP setting (optional). UseConnection must be True to use this setting. This option allows you to specify an arbitrary DSCP value between 0 and 63. The default is 0. When set to the default value the component will not set a DSCP value. Note: This setting uses the qWAVE API is only available on Windows 7, Windows Server 2008 R2, and later.

QOSTrafficType:   Used to specify QOS/DSCP settings (optional). UseConnection must be True to use this setting. You may specify either the text or integer values: BestEffort (0), Background (1), ExcellentEffort (2), AudioVideo (3), Voice (4), and Control (5). Note: This setting uses the qWAVE API which is only available on Windows Vista and Windows Server 2008 or above. Note: QOSTrafficType must be set before setting Active to true.

ShareLocalPort:   If set to True, allows more than one instance of the component to be active on the same local port. This option must be set before the component is activated through the Active property or it will have no effect. The default value for this setting is False.

UseConnection:   Determines whether to use a connected socket. UseConnection specifies whether the component should use a connected socket or not. 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 TCP sense. What it means is only that the component will send and receive data only to and from the specified destination. The default value for this setting is False.

UseIPv6:   Whether or not to use IPv6. By default, the component expects an IPv4 address for local and remote host properties, and will create an IPv4 socket. To use IPv6 instead, set this to True.

Socket Config Settings

AbsoluteTimeout:   Determines whether timeouts are inactivity timeouts or absolute timeouts. If AbsoluteTimeout is set to True, any method which 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 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 TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. Increasing the value of the InBufferSize setting can provide significant improvements in performance in some cases. Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the component 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. Increasing the value of the OutBufferSize setting can provide significant improvements in performance in some cases. Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the component is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

Base Config Settings

BuildInfo:   Information about the product's build. When queried, this setting will return a string containing information about the product's build.

CodePage:   The system code page used for Unicode to Multibyte translations. The default code page is Unicode UTF-8 (65001). The following is a list of valid code page identifiers: Identifier Name 037 IBM EBCDIC - U.S./Canada 437 OEM - United States 500 IBM EBCDIC - International 708 Arabic - ASMO 708 709 Arabic - ASMO 449+, BCON V4 710 Arabic - Transparent Arabic 720 Arabic - Transparent ASMO 737 OEM - Greek (formerly 437G) 775 OEM - Baltic 850 OEM - Multilingual Latin I 852 OEM - Latin II 855 OEM - Cyrillic (primarily Russian) 857 OEM - Turkish 858 OEM - Multilingual Latin I + Euro symbol 860 OEM - Portuguese 861 OEM - Icelandic 862 OEM - Hebrew 863 OEM - Canadian-French 864 OEM - Arabic 865 OEM - Nordic 866 OEM - Russian 869 OEM - Modern Greek 870 IBM EBCDIC - Multilingual/ROECE (Latin-2) 874 ANSI/OEM - Thai (same as 28605, ISO 8859-15) 875 IBM EBCDIC - Modern Greek 932 ANSI/OEM - Japanese, Shift-JIS 936 ANSI/OEM - Simplified Chinese (PRC, Singapore) 949 ANSI/OEM - Korean (Unified Hangul Code) 950 ANSI/OEM - Traditional Chinese (Taiwan;

LicenseInfo:   Information about the current license. When queried, this setting will return a string containing information about the license this instance of a component is using. It will return the following information: Product: The product the license is for. Product Key: The key the license was generated from. License Source: Where the license was found (e.g., RuntimeLicense, License File). License Type: The type of license installed (e.g., Royalty Free, Single Server). Last Valid Build: The last valid build number for which the license will work.

MaskSensitive:   Whether sensitive data is masked in log messages. In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to true to mask sensitive data. The default is false. This setting only works on these components: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

UseInternalSecurityAPI:   Tells the component whether or not to use the system security libraries or an internal implementation. When set to false, the component will use the system security libraries by default to perform cryptographic functions where applicable. Setting this setting to true tells the component to use the internal implementation instead of using the system security libraries. This setting is set to false by default on all platforms.
