The FTP Component can be used to transfer files to and from FTP servers using the FTP protocol.

Syntax

TipwFTP

Remarks

The FTP Component supports both plaintext and Secure Sockets Layer/Transport Layer Security (SSL/TLS) connections. When connecting over Secure Sockets Layer/Transport Layer Security (SSL/TLS) the SSLServerAuthentication event allows you to check the server identity and other security attributes. The SSLStatus event provides information about the SSL handshake. Additional SSL-related settings are also supported through the Config method.

The FTP Component implements a standard FTP client as specified in RFC 959 and RFC 1579 with the added option of SSL security (RFC 2228) in both the protocol and data channels.

The first step in using the component is specifying the RemoteHost, User and Password. The file to upload to or download from is given by the RemoteFile property. The file to download to or upload from is specified by LocalFile. The current path in the server is set by calling ChangeRemotePath. The Passive property is especially useful if the client is behind a firewall, which inhibits incoming connections to higher ports.

If LocalFile is set to something other than an empty string, then files are received in LocalFile, and otherwise data are received through the Transfer event. StartTransfer and EndTransfer are fired at the beginning and end of transmission.

The PITrail event traces the interaction between the client and the server (the FTP protocol interface connection).

Directory listings are received through the DirList event.

This property is read-only.

Data Type

String

LocalFile Property (FTP Component)

This is the path to a local file for download or upload. If the file exists, it is overwritten.

Syntax

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

Default Value

""

Remarks

This property is used by the Upload and Download methods to specify the path to a local file to be downloaded or uploaded. See the method descriptions for more information.

Example (Setting LocalFile)

FTPControl.LocalFile = "C:\localfile.txt" FTPControl.RemoteFile = "remotefile.txt" FTPControl.Download() FTPControl.LocalFile = "C:\localfile2.txt" FTPControl.RemoteFile = "folder/remotefile2.txt" FTPControl.Download()

Data Type

String

LocalHost Property (FTP 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

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 component initiate connections (or accept in the case of server components) 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 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 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

Overwrite Property (FTP Component)

This indicates whether or not the component should overwrite files during transfer.

Syntax

__property bool Overwrite = { read=FOverwrite, write=FSetOverwrite };

Default Value

false

Remarks

This property is a value indicating whether or not the component should overwrite downloaded files. If Overwrite is False, an error will be thrown whenever LocalFile exists before a download operation.

Data Type

Boolean

Passive Property (FTP Component)

This controls whether or not to direct the server into a passive mode. It is recommended if behind a firewall.

Syntax

__property bool Passive = { read=FPassive, write=FSetPassive };

Default Value

true

Remarks

This property controls whether or not to direct the server into a passive mode. Many firewalls will not allow the FTP server to open a connection from outside to the higher ports where the FTP client component expects them to be. If Passive is set to TRUE, the component will use the PASV command instead of the PORT command and thus will direct the server into a passive mode: connections are initiated only by the client.

Data Type

Boolean

Password Property (FTP Component)

This is the password used to log in.

Syntax

__property String Password = { read=FPassword, write=FSetPassword };

Default Value

""

Remarks

This property contains the password used to log in. It must be set before the component connects to the FTP server.

Data Type

String

RemoteFile Property (FTP Component)

This is the name of the remote file for uploading, downloading, and performing other operations.

Syntax

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

Default Value

""

Remarks

This property contains the name of the remote file to be uploaded or downloaded and is either an absolute file path or a relative path based on the remote path set by calling ChangeRemotePath.

A number of methods use RemoteFile as an argument.

Example 1. Setting RemoteFile:

FTPControl.LocalFile = "C:\localfile.txt" FTPControl.RemoteFile = "remotefile.txt" FTPControl.Download() FTPControl.LocalFile = "C:\localfile2.txt" FTPControl.RemoteFile = "folder/remotefile2.txt" FTPControl.Download()

Note: As long as file masks are supported by the server, then this property will act as a file mask when performing ListDirectory or ListDirectoryLong. If not supported, then ApplyFileMaskLocally could be set to True to filter the results locally.

Example 2. Using RemoteFile as a file mask: FTPControl.RemoteFile = "*.txt" FTPControl.ListDirectory()

The following special characters are supported for pattern matching:

If these characters need to be used as a literal in a pattern, then they must be escaped by surrounding them with brackets []. Note: "]" and "-" do not need to be escaped. See below for the escape sequences:

For example, to match the value [Something].txt, specify the pattern [[]Something].txt.

Data Type

String

RemoteHost Property (FTP Component)

This is the domain name or IP address of the FTP server.

Syntax

__property String RemoteHost = { read=FRemoteHost, write=FSetRemoteHost };

Default Value

""

Remarks

This property specifies the IP address (IP number in dotted internet format) or the domain name of the FTP server. It is set before a connection is attempted and cannot be changed once a connection is in progress.

If this property is set to a domain name, a DNS request is initiated and upon successful termination of the request, this property is set to the corresponding address. If the search is not successful, an error is returned.

If the component is configured to use a SOCKS firewall, the value assigned to this property may be preceded with an "*". If this is the case, the host name is passed to the firewall unresolved and the firewall performs the DNS resolution.

Data Type

String

RemotePort Property (FTP Component)

This is the port for the FTP service (default is 21).

Syntax

__property int RemotePort = { read=FRemotePort, write=FSetRemotePort };

Default Value

21

Remarks

This property contains the port for the FTP service, which defaults to 21 if not set. A valid port number (a value between 1 and 65535) is required for the connection to take place. The property must be set before a connection is attempted and cannot be changed once a connection is established. Any attempt to change this property while connected will fail with an error.

For an implicit Secure Sockets Layer (SSL), use port 990 (please see the SSLStartMode property for more information).

This property is not available at design time.

Data Type

The subject of the certificate used for client authentication.

Syntax

__property String SSLServerCertSubject = { read=FSSLServerCertSubject };

Default Value

""

Remarks

The subject of the certificate used for client authentication.

This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject.

If a matching certificate is found, the property is set to the full subject of the matching certificate.

If an exact match is not found, the store is searched for subjects containing the value of the property.

If a match is still not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks a random certificate in the certificate store.

The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are as follows:

This property is read-only.

Data Type

String

SSLServerCertEncoded Property (FTP Component)

The certificate (PEM/Base64 encoded).

Syntax

__property String SSLServerCertEncoded = { read=FSSLServerCertEncoded };
__property DynamicArray<Byte> SSLServerCertEncodedB = { read=FSSLServerCertEncodedB };

Default Value

""

Remarks

The certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The SSLServerCertStore and SSLServerCertSubject properties also may be used to specify a certificate.

When SSLServerCertEncoded is set, a search is initiated in the current SSLServerCertStore for the private key of the certificate. If the key is found, SSLServerCertSubject is updated to reflect the full subject of the selected certificate; otherwise, SSLServerCertSubject is set to an empty string.

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

Data Type

Byte Array

SSLStartMode Property (FTP Component)

This property determines how the component starts the Secure Sockets Layer (SSL) negotiation.

Syntax

__property TipwFTPSSLStartModes SSLStartMode = { read=FSSLStartMode, write=FSetSSLStartMode };

enum TipwFTPSSLStartModes {
  sslAutomatic=0,
  sslImplicit=1,
  sslExplicit=2,
  sslNone=3
};

Default Value

sslNone

Remarks

The SSLStartMode property may have one of the following values:

Data Type

Integer

StartByte Property (FTP Component)

This is the byte index in RemoteFile and LocalFile from which to start a transmission.

Syntax

__property String StartByte = { read=FStartByte, write=FSetStartByte };

Default Value

"0"

Remarks

This property contains a zero-based index in both RemoteFile and LocalFile that determines the point from which the transmission of data begins. This is useful for resuming interrupted downloads and uploads of files from FTP servers.

Once set, the StartByte index is used for all future downloads and uploads. The property must be reset to "0" for normal downloads and uploads.

The type of the property is a string instead of numeric value to allow for certain implementations that expect an alphanumeric marker for the start index.

In the Transfer event, the TransferredBytes parameter will include the bytes skipped (i.e., it will show StartByte more bytes than actually transferred).

Note: Some FTP servers may not support the FTP REST command. If that is the case with the server you are accessing, you will not be able to use the StartByte property.

This property is not available at design time.

Data Type

String

Timeout Property (FTP Component)

The 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.

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

TransferMode Property (FTP Component)

This property indicates the transfer mode (ASCII or binary). If the value is 0 (default), the initial server mode will be used.

Syntax

__property TipwFTPTransferModes TransferMode = { read=FTransferMode };

enum TipwFTPTransferModes {
  tmDefault=0,
  tmASCII=1,
  tmBinary=2
};

Default Value

tmDefault

Remarks

This property indicates the current transfer mode, which is either ASCII or binary. To change the transfer mode call the ChangeTransferMode method. Possible values for this property are:

This property is read-only.

Data Type

Integer

User Property (FTP Component)

This property contains the user identifier to use to log in.

Syntax

__property String User = { read=FUser, write=FSetUser };

Default Value

""

Remarks

This property contains the user identifier to be used when logging in. It must be set before the component connects to the FTP server.

Data Type

String

Abort Method (FTP Component)

The method aborts the current upload or download.

Syntax

void __fastcall Abort();

Remarks

This method sends an ABOR command to the FTP server. It is used to interrupt file uploads and downloads.

Append Method (FTP Component)

This method appends data from LocalFile to a RemoteFile on an FTP server.

Syntax

void __fastcall Append();

Remarks

This method causes the server-data transfer process (DTP) to accept the data transferred through the data connection and to store the data in a file on the server site. If the file specified in the pathname exists on the server site, then the data shall be appended to that file; otherwise, the file specified in the pathname shall be created on the server site. This method is similar to the Upload method, but the local file specified by LocalFile is appended to RemoteFile on the server as opposed to replacing it, as with the Upload method. RemoteFile is either an absolute path on the server, or a path relative to the current path set by ChangeRemotePath. The server will create a file with that name if it doesn't already exist (similar to upload). If no FTP session is in place, one is automatically created by first calling the Logon method.

ChangeRemotePath Method (FTP Component)

This method changes the current path on the FTP server.

Syntax

void __fastcall ChangeRemotePath(String RemotePath);

Remarks

This method changes the current path on the FTP server to the specified RemotePath. When called, the component will issue a command to the server to change the directory. The RemotePath parameter may hold an absolute or relative path.

Absolute Paths

If the path begins with a /, it is considered an absolute path and must specify the entire path from the root of the server. For instance:

component.ChangeRemotePath("/home/testuser/myfolder");

Relative Paths

If the path does not begin with a /, it is considered a relative path and is resolved in relation to the current directory. For instance, a value of myfolder will indicate a subfolder of the current directory. The special value .. refers to the parent directory of the current path. For instance:

//Change to the 'myfolder' sub-directory component.ChangeRemotePath("myfolder"); //Navigate up two levels and then into the 'another/folder' path. component.ChangeRemotePath("../../another/folder");

ChangeTransferMode Method (FTP Component)

This method changes the transfer mode for the current connection.

Syntax

void __fastcall ChangeTransferMode(int TransferMode);

Remarks

This method optionally changes the transfer mode used for the connection. The TransferMode parameter indicates the new transfer mode to be used.

In many cases, it is not necessary to explicitly change the transfer mode; however, the binary transfer mode is useful to ensure that files are preserved byte-for-byte during the transfer. For instance, when uploading or downloading images or archives, the binary transfer mode will ensure that no line-ending transformations are performed by the server before data are transmitted.

Valid values for the TransferMode parameter are as follows:

CheckFileExists Method (FTP Component)

This method returns True if the file specified by RemoteFile exists on the server.

Syntax

bool __fastcall CheckFileExists();

Remarks

This method sends a command to the server to determine if the file specified by RemoteFile exists. If the file exists, this method returns true, otherwise it returns false. RemoteFile must be specified before calling this method. For instance: component.ChangeRemotePath("/home/testuser/myfolder"); component.RemoteFile = "test.txt"; if(component.CheckFileExists()) { //Do something }

Config Method (FTP 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.

Connect Method (FTP Component)

This method connects to the FTP server without logging in.

Syntax

void __fastcall Connect();

Remarks

This method establishes a connection with the RemoteHost but does not log in. In most cases, it is recommended to use the Logon method, which will both establish a connection and log in to the server.

This method may be useful in cases in which it is desirable to separate the connection and logon operations, for instance, confirming that a host is available by first creating the connection.

DelFile Method (FTP Component)

This method removes a file specified by FileName from an FTP server.

Syntax

void __fastcall DelFile(String FileName);

Remarks

Disconnect Method (FTP Component)

This method disconnects from the server without first logging off.

Syntax

void __fastcall Disconnect();

Remarks

This method immediately disconnects from the server without first logging off.

In most cases, the Logoff method should be used to log off and disconnect from the server. Call the Disconnect method in cases in which it is desirable to immediately disconnect without first logging off.

DoEvents Method (FTP Component)

This method 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.

Download Method (FTP Component)

This method downloads a RemoteFile from an FTP server.

Syntax

void __fastcall Download();

Remarks

This method is used to download the remote file specified by RemoteFile to the local file specified by LocalFile, or it is retrieved through the Transfer event if the LocalFile property is "" (empty string). RemoteFile is either an absolute path on the server or a path relative to a remote path set by calling ChangeRemotePath. If no FTP session is in place, one is automatically created by first calling the Logon method.

Example (Download a File)

FTPControl.LocalFile = "C:\localfile.txt" FTPControl.RemoteFile = "remotefile.txt" FTPControl.Download() FTPControl.LocalFile = "C:\localfile2.txt" FTPControl.RemoteFile = "folder/remotefile2.txt" FTPControl.Download()

Interrupt Method (FTP Component)

This method interrupts the current method.

Syntax

void __fastcall Interrupt();

Remarks

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

ListDirectory Method (FTP Component)

List the current directory specified by ChangeRemotePath on an FTP server.

Syntax

void __fastcall ListDirectory();

Remarks

This method is used to list the directory (or file mask) specified in RemoteFile. RemoteFile is either an absolute path on the server, or a path relative to the remote path set by ChangeRemotePath. The file listing is received through the DirList event.

Similar to ListDirectoryLong, except that only file names are returned.

Note: Because RemoteFile acts as a file mask, to retrieve a complete directory listing RemoteFile should be set to an empty string or a mask like "*". If no FTP session is in place, one is automatically created by first calling the Logon method.

ListDirectoryLong Method (FTP Component)

This method lists extended directory information for the remote path specified by calling ChangeRemotePath .

Syntax

void __fastcall ListDirectoryLong();

Remarks

This method is used to request a directory (or file mask) listing specified in RemoteFile. RemoteFile is either an absolute path on the server, or a path relative to the remote path set by calling ChangeRemotePath. The file listing is received through the DirList event. Extended file information is returned.

Note: Because RemoteFile acts as a file mask, to retrieve a complete directory listing RemoteFile should be set to empty string or a mask like "*". If no FTP session is in place, one is automatically created by first calling the Logon method.

Logoff Method (FTP Component)

This method is used to log off from the FTP server by posting a QUIT command.

Syntax

void __fastcall Logoff();

Remarks

This method is used to log off from the FTP server by posting a QUIT command. If that fails, the connection is terminated by the local host.

Logon Method (FTP Component)

This method is used to log on to the FTP RemoteHost using the current User and Password .

Syntax

void __fastcall Logon();

Remarks

This method is used to log on to the FTP server using the current User and Password. If TransferMode is not 0 (Default), then the FTP transfer mode is set to the appropriate value.

Example (Logging On)

FTPControl.RemoteHost = "ftpserver" FTPControl.User = "username" FTPControl.Password = "password" FTPControl.Logon()

MakeDirectory Method (FTP Component)

This method is used to create a directory on the FTP server.

Syntax

void __fastcall MakeDirectory(String NewDir);

Remarks

This method is used to create a directory with a path specified by NewDir on the FTP server. NewDir is either an absolute path on the server, or a path relative to the remote path that is set by calling ChangeRemotePath. If no FTP session is in place, one is automatically created by first calling the Logon method.

Note: When MakeDirectory is called, RemoteFile is changed to NewDir.

QueryFileSize Method (FTP Component)

This returns the size of the file specified by RemoteFile .

Syntax

__int64 __fastcall QueryFileSize();

Remarks

This method sends the SIZE command to the server to obtain the size (in bytes) of the file specified by RemoteFile. RemoteFile must be specified before calling this method. For instance: component.ChangeRemotePath("/home/testuser/myfolder"); component.RemoteFile = "test.txt"; long myFileSize = component.QueryFileSize();

If RemoteFile does not exist on the server, the component raises an exception.

QueryFileTime Method (FTP Component)

This returns the modified time of the file specified by RemoteFile .

Syntax

String __fastcall QueryFileTime();

Remarks

This method sends the MDTM command to the server to obtain the modified time of the file specified by RemoteFile. The time returned by this method will be converted to the local timezone. RemoteFile must be specified before calling this method. For instance: component.ChangeRemotePath("/home/testuser/myfolder"); component.RemoteFile = "test.txt"; string myModifiedTime = component.QueryFileTime();

The FileTimeFormat configuration setting controls the format of the returned value.

QueryRemotePath Method (FTP Component)

This queries the server for the current path.

Syntax

String __fastcall QueryRemotePath();

Remarks

This method queries the server for the current path. When called, the component will issue a command to the server to retrieve the current path value. The return value of this method is the path returned by the server. For instance:

string remotePath = component.QueryRemotePath();

RmDir Method (FTP Component)

This removes a directory specified by DirName from an FTP server.

Syntax

void __fastcall RmDir(String DirName);

Remarks

RenameFile Method (FTP Component)

This changes the name of RemoteFile to NewName .

Syntax

void __fastcall RenameFile(String NewName);

Remarks

This method is used to change the name of a remote file, specified by RemoteFile to NewName. RemoteFile and NewName are either absolute paths on the server, or a path relative to a remote path set by calling ChangeRemotePath. If no FTP session is in place, one is automatically created by first calling the Logon method.

Reset Method (FTP Component)

This method will reset the component.

Syntax

void __fastcall Reset();

Remarks

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

SendCommand Method (FTP Component)

This method sends the exact command directly to the server.

Syntax

void __fastcall SendCommand(String Command);

Remarks

This method sends the command specified by Command to the server exactly as it is provided. Use this method to send additional or custom commands directly to the server.

After calling this method, check the LastReply property or monitor the PITrail event to obtain the server's response.

StoreUnique Method (FTP Component)

This method uploads a file with a unique name to an FTP server.

Syntax

void __fastcall StoreUnique();

Remarks

This method is used to upload a file with a unique name to an FTP server. This is similar to the Upload method, but the server determines a unique name for the LocalFile to be saved on the current directory set by calling ChangeRemotePath. The server includes the new name of the file in its response. The user should check the PITrail event, or LastReply property to retrieve this generated filename.

Upload Method (FTP Component)

This method uploads a file specified by LocalFile to an FTP server.

Syntax

void __fastcall Upload();

Remarks

This method uploads a local file specified by LocalFile to the remote file specified by RemoteFile. RemoteFile is either an absolute path on the server, or a path relative to the remote path set by calling ChangeRemotePath. If no FTP session is in place, one is automatically created by first calling the Logon method.

If you want to append to a server file, please refer to the Append method.

Example 1: Upload a File

FTPControl.LocalFile = "C:\localfile.txt" FTPControl.RemoteFile = "remotefile.txt" FTPControl.Upload() FTPControl.LocalFile = "C:\localfile2.txt" FTPControl.RemoteFile = "folder/remotefile2.txt" FTPControl.Upload()

ConnectionStatus Event (FTP Component)

Fired to indicate changes in the connection state.

Syntax

typedef struct {
  String ConnectionEvent;
  int StatusCode;
  String Description;
} TipwFTPConnectionStatusEventParams;
typedef void __fastcall (__closure *TipwFTPConnectionStatusEvent)(System::TObject* Sender, TipwFTPConnectionStatusEventParams *e);
__property TipwFTPConnectionStatusEvent OnConnectionStatus = { read=FOnConnectionStatus, write=FOnConnectionStatus };

Remarks

This event is fired when the connection state changes: for example, completion of a firewall or proxy connection or completion of a security handshake.

The ConnectionEvent parameter indicates the type of connection event. Values may include the following:

DirList Event (FTP Component)

This event is fired when a directory entry is received.

Syntax

typedef struct {
  String DirEntry;
  String FileName;
  bool IsDir;
  __int64 FileSize;
  String FileTime;
} TipwFTPDirListEventParams;
typedef void __fastcall (__closure *TipwFTPDirListEvent)(System::TObject* Sender, TipwFTPDirListEventParams *e);
__property TipwFTPDirListEvent OnDirList = { read=FOnDirList, write=FOnDirList };

Remarks

The DirList events are fired when a directory listing is received as a response to a ListDirectory or ListDirectoryLong call.

The StartTransfer and EndTransfer events mark the beginning and end of the event stream.

The DirEntry parameter contains the filename when ListDirectory is called and includes extended file information when ListDirectoryLong is called.

The component tries to fill out the FileName, IsDir, FileSize, and FileTime parameters when calling the ListDirectoryLong method. Except for FileName, these parameters are empty when a short "List Directory" is performed.

In Unix systems, the date is given in two types of formats: If the date is in the past 12 months the exact time is specified and the year is omitted. Otherwise, only the date and the year, but not hours or minutes, are given.

EndTransfer Event (FTP Component)

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

Syntax

typedef struct {
  int Direction;
} TipwFTPEndTransferEventParams;
typedef void __fastcall (__closure *TipwFTPEndTransferEvent)(System::TObject* Sender, TipwFTPEndTransferEventParams *e);
__property TipwFTPEndTransferEvent 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 (FTP Component)

Fired when information is available about errors during data delivery.

Syntax

typedef struct {
  int ErrorCode;
  String Description;
} TipwFTPErrorEventParams;
typedef void __fastcall (__closure *TipwFTPErrorEvent)(System::TObject* Sender, TipwFTPErrorEventParams *e);
__property TipwFTPErrorEvent 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.

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.

PITrail Event (FTP Component)

This event traces the commands sent to the server, and the respective replies.

Syntax

typedef struct {
  int Direction;
  String Message;
} TipwFTPPITrailEventParams;
typedef void __fastcall (__closure *TipwFTPPITrailEvent)(System::TObject* Sender, TipwFTPPITrailEventParams *e);
__property TipwFTPPITrailEvent OnPITrail = { read=FOnPITrail, write=FOnPITrail };

Remarks

The PITrail event is useful for debugging purposes. It shows all of the interactions between the client and the server, line by line.

The Message parameter contains the full text of the message. The Direction parameter shows the originator of the message:

SSLServerAuthentication Event (FTP Component)

Fired after the server presents its certificate to the client.

Syntax

typedef struct {
  String CertEncoded;
  DynamicArray<Byte> CertEncodedB;
  String CertSubject;
  String CertIssuer;
  String Status;
  bool Accept;
} TipwFTPSSLServerAuthenticationEventParams;
typedef void __fastcall (__closure *TipwFTPSSLServerAuthenticationEvent)(System::TObject* Sender, TipwFTPSSLServerAuthenticationEventParams *e);
__property TipwFTPSSLServerAuthenticationEvent OnSSLServerAuthentication = { read=FOnSSLServerAuthentication, write=FOnSSLServerAuthentication };

Remarks

During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

SSLStatus Event (FTP Component)

Fired when secure connection progress messages are available.

Syntax

typedef struct {
  String Message;
} TipwFTPSSLStatusEventParams;
typedef void __fastcall (__closure *TipwFTPSSLStatusEvent)(System::TObject* Sender, TipwFTPSSLStatusEventParams *e);
__property TipwFTPSSLStatusEvent OnSSLStatus = { read=FOnSSLStatus, write=FOnSSLStatus };

Remarks

The event is fired for informational and logging purposes only. This event tracks the progress of the connection.

StartTransfer Event (FTP Component)

This event fires when a file starts downloading or uploading.

Syntax

typedef struct {
  int Direction;
} TipwFTPStartTransferEventParams;
typedef void __fastcall (__closure *TipwFTPStartTransferEvent)(System::TObject* Sender, TipwFTPStartTransferEventParams *e);
__property TipwFTPStartTransferEvent 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 (FTP 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;
} TipwFTPTransferEventParams;
typedef void __fastcall (__closure *TipwFTPTransferEvent)(System::TObject* Sender, TipwFTPTransferEventParams *e);
__property TipwFTPTransferEvent 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.
