The HTMLMailer Class is used to send HTML emails, including embedded images.

Syntax

HTMLMailer

Remarks

The HTMLMailer Class supports both plaintext and Secure Sockets Layer/Transport Layer Security (SSL/TLS) connections (RFC 2487). When connecting over 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 via the Config method.

The class sends a message (provided in MessageHTML and MessageText). The HTML message may contain references to images that are automatically embedded into the message.

The MessageHTML property contains the HTML version of the message. The corresponding plaintext version is provided in the MessageText property.

When MessageHTML is set, the class automatically computes a plaintext version of the text and puts it into MessageText. You may choose to override this default text with your own version.

The recipients are specified by the SendTo, Cc, and BCc properties, and the message subject by the Subject property.

Once all the appropriate properties have been set, call the Send method and your message will be sent to its intended recipient(s).

Other SMTP headers may be specified through the OtherHeaders property. Information about interaction with the server is provided by the PITrail event.

QString GetBCc();
int SetBCc(QString qsBCc);

Default Value

""

Remarks

This property specifies a comma-separated list of destinations for blind carbon copies of the mail message. A copy of the message is sent to each destination. Because no BCc SMTP header is created containing the destination addresses, individual recipients never see the list of the other recipients.

The class will return an error if the MailServer returns an error code about any email address specified in SendTo or Cc but it will fire an Error event only if the same thing happens with an email address specified in this property.

If the resulting header is longer than MaxHeaderLength, then it is folded according to RFC 822 specifications.

Note: You must clear the MessageRecipients properties before setting this property to remove previous recipients.

Data Type

A copy of the message is sent to each destination, and a Cc SMTP header is created containing the destination addresses. This header is sent to every recipient of the message. If you don't want to copy this information to every recipient, then use blind carbon copies instead (see the description of the BCc).

The class will return an error if the MailServer returns an error code about any email address specified in SendTo or Cc but it will fire an Error event only if the same thing happens with an email address specified in BCc.

If the resulting header is longer than MaxHeaderLength, then it is folded according to RFC 822 specifications.

Note: You must clear the MessageRecipients properties before setting this property to remove previous recipients.

""

Remarks

This property specifies the IP address (IP number in dotted internet format) or Domain Name for a mail relay through which messages will be routed. It is set before a connection is attempted and cannot be changed once a connection is in progress.

The current version of the class does not provide a default value for the mail relay. You must provide a host name yourself. Generally, any internet host with an SMTP server will suffice (a UNIX host for example), but it is preferable to select a MailServer that is close to the machine sending mail.

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 class 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.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int GetSSLStartMode();
int SetSSLStartMode(int iSSLStartMode);

Unicode (Windows)
INT GetSSLStartMode();
INT SetSSLStartMode(INT iSSLStartMode);

SSL_AUTOMATIC(0), 
SSL_IMPLICIT(1), 
SSL_EXPLICIT(2)

int ipworksssl_htmlmailer_getsslstartmode(void* lpObj);
int ipworksssl_htmlmailer_setsslstartmode(void* lpObj, int iSSLStartMode);

int GetSSLStartMode();
int SetSSLStartMode(int iSSLStartMode);

Default Value

0

Remarks

The SSLStartMode property may have one of the following values:

Data Type

Integer

Subject Property (HTMLMailer Class)

The subject of the mail message (optional).

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* GetSubject();
int SetSubject(const char* lpszSubject);

Unicode (Windows)
LPWSTR GetSubject();
INT SetSubject(LPCWSTR lpszSubject);

char* ipworksssl_htmlmailer_getsubject(void* lpObj);
int ipworksssl_htmlmailer_setsubject(void* lpObj, const char* lpszSubject);

QString GetSubject();
int SetSubject(QString qsSubject);

Default Value

""

Remarks

The string in this property is sent with a Subject SMTP header to the mail recipient.

If the resulting header is longer than MaxHeaderLength, then it is folded according to RFC 822 specifications.

Data Type

String

Timeout Property (HTMLMailer Class)

A timeout for the class.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int GetTimeout();
int SetTimeout(int iTimeout);

Unicode (Windows)
INT GetTimeout();
INT SetTimeout(INT iTimeout);

int ipworksssl_htmlmailer_gettimeout(void* lpObj);
int ipworksssl_htmlmailer_settimeout(void* lpObj, int iTimeout);

int GetTimeout();
int SetTimeout(int iTimeout);

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

The class 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 class fails with an error.

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

User Property (HTMLMailer Class)

A user identifier to login as in the MailServer .

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* GetUser();
int SetUser(const char* lpszUser);

Unicode (Windows)
LPWSTR GetUser();
INT SetUser(LPCWSTR lpszUser);

char* ipworksssl_htmlmailer_getuser(void* lpObj);
int ipworksssl_htmlmailer_setuser(void* lpObj, const char* lpszUser);

QString GetUser();
int SetUser(QString qsUser);

Default Value

""

Remarks

If this property is set to a non-empty string, then when connecting to the MailServer an AUTH or CRAM-MD5 (depending on the value of AuthMechanism) command is sent in order to provide authentication information for the user.

This property is not available at design time.

Data Type

String

AddAttachment Method (HTMLMailer Class)

This adds FileName as an attachment.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int AddAttachment(const char* lpszFileName);

Unicode (Windows)
INT AddAttachment(LPCWSTR lpszFileName);

int ipworksssl_htmlmailer_addattachment(void* lpObj, const char* lpszFileName);

int AddAttachment(const QString& qsFileName);

Remarks

This method adds the file name as an attachment. The full list of attachments is contained in the Attachments property.

Example 1: Adding an Attachment

component.AddAttachment("C:\file1.zip"); component.AddAttachment("C:\file2.zip"); component.Send(); Example 3: Using an Attachments Array

component.AttachmentCount = 1; component.AttachmentName(0) = "name"; component.AttachmentFile(0) = "C:\file.txt";

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

CalcMessageText Method (HTMLMailer Class)

This method populates MessageText with the plaintext version of the message.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int CalcMessageText();

Unicode (Windows)
INT CalcMessageText();

int ipworksssl_htmlmailer_calcmessagetext(void* lpObj);

int CalcMessageText();

Remarks

This method parses MessageHTML or HTMLFile and calculates a plaintext version of the message. The plaintext version is stored in the MessageText property.

Calling this method is optional. When the Send method is called, the class will automatically calculate a plaintext version of the message. This may be called in cases in which the plaintext version will be set explicitly. For instance:

component.MessageHTML="<html><body><b>Test Message</b></body></html>"; component.CalcMessageText(); component.MessageText = "A new custom plaintext message";

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Config Method (HTMLMailer Class)

Sets or retrieves a configuration setting.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* Config(const char* lpszConfigurationString);

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);

char* ipworksssl_htmlmailer_config(void* lpObj, const char* lpszConfigurationString);

QString Config(const QString& qsConfigurationString);

Remarks

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

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, 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.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

Connect Method (HTMLMailer Class)

This method connects to the mail relay and sends the SMTP HELO command.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int Connect();

Unicode (Windows)
INT Connect();

int ipworksssl_htmlmailer_connect(void* lpObj);

int Connect();

Remarks

This method connects to the mail relay and sends the SMTP HELO command, thus preparing to send messages. Any number of messages can later be sent using the Send method.

Example. Connecting and Sending an Email:

control.MailServer = "MyServer" control.From = "me@server.com" control.SendTo = "recipient@server.com" control.Subject = "My Subject" control.MessageText = "This is the message body" control.Connect() control.Send() control.Disconnect()

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Disconnect Method (HTMLMailer Class)

This method disconnects from the SMTP server.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int Disconnect();

Unicode (Windows)
INT Disconnect();

int ipworksssl_htmlmailer_disconnect(void* lpObj);

int Disconnect();

Remarks

This method disconnects from the mail relay.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

DoEvents Method (HTMLMailer Class)

Processes events from the internal message queue.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int DoEvents();

Unicode (Windows)
INT DoEvents();

int ipworksssl_htmlmailer_doevents(void* lpObj);

int DoEvents();

Remarks

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

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Interrupt Method (HTMLMailer Class)

Interrupt the current method.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int Interrupt();

Unicode (Windows)
INT Interrupt();

int ipworksssl_htmlmailer_interrupt(void* lpObj);

int Interrupt();

Remarks

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

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

ProcessQueue Method (HTMLMailer Class)

Sends the messages which have previously been queued into QueueDir .

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int ProcessQueue(const char* lpszQueueDir);

Unicode (Windows)
INT ProcessQueue(LPCWSTR lpszQueueDir);

int ipworksssl_htmlmailer_processqueue(void* lpObj, const char* lpszQueueDir);

int ProcessQueue(const QString& qsQueueDir);

Remarks

This method sends the messages which have previously been queued into QueueDir. The PITrail event shows the interaction with the server as messages as are processed.

This method looks in the directory for files with extension ".queued" and starts processing them.

When processing starts, the file extension is changed to ".sending". If an error happens at this stage, the sending process is aborted, and the file extension is changed to ".failed".

If the file is successfully sent, the file is normally deleted, unless the KeepQueue configuration setting is set to True, in which case the file extension is instead changed to ".sent" and the queue file is not deleted.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Queue Method (HTMLMailer Class)

Queues the message into QueueDir .

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* Queue(const char* lpszQueueDir);

Unicode (Windows)
LPWSTR Queue(LPCWSTR lpszQueueDir);

char* ipworksssl_htmlmailer_queue(void* lpObj, const char* lpszQueueDir);

QString Queue(const QString& qsQueueDir);

Remarks

This method queues the message into QueueDir. The message is queued into a unique file into the directory QueueDir for future processing.

QueueDir must already exist, or an error will be generated. Alternatively, QueueDir may be set to "*" to return the result as a string instead of writing it to a file.

The method returns the name of the unique queue file created in QueueDir. The file extension is ".queued".

Please refer to the ProcessQueue method for more information on email queue processing.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

Reset Method (HTMLMailer Class)

Reset the class.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int Reset();

Unicode (Windows)
INT Reset();

int ipworksssl_htmlmailer_reset(void* lpObj);

int Reset();

Remarks

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

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

ResetHeaders Method (HTMLMailer Class)

Resets all the message headers to empty.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int ResetHeaders();

Unicode (Windows)
INT ResetHeaders();

int ipworksssl_htmlmailer_resetheaders(void* lpObj);

int ResetHeaders();

Remarks

This method resets all the message headers to "" (empty string). Use this method before creating a new message, so that headers from the previous message are not carried over to the next one.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Send Method (HTMLMailer Class)

This method sends the current message and MIME-encoded attachment.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int Send();

Unicode (Windows)
INT Send();

int ipworksssl_htmlmailer_send(void* lpObj);

int Send();

Remarks

This method sends the current message and MIME-encoded attachment. If the class is not connected to the mail relay, a connection is created, the message is sent, and then the connection is closed unless an error occurs.

If the class is already connected (by use of the Connect method), the connection will remain open after the message is sent. To disconnect, call the Disconnect method.

Example. Send an HTML Email:

HTMLMailerControl.MailServer = "myserver" HTMLMailerControl.SendTo = "recipient@myserver.com" HTMLMailerControl.From = "me@myserver.com" HTMLMailerControl.Subject = "My Subject" HTMLMailerControl.MessageHTML = "<b>Hello</b>, my name is <i>Tom</i>" HTMLMailerControl.Send

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

SendCommand Method (HTMLMailer Class)

Sends the exact command directly to the server.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int SendCommand(const char* lpszCommand);

Unicode (Windows)
INT SendCommand(LPCWSTR lpszCommand);

int ipworksssl_htmlmailer_sendcommand(void* lpObj, const char* lpszCommand);

int SendCommand(const QString& qsCommand);

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 and/or monitor the PITrail event to obtain the server's response.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

SetMessageHTMLStream Method (HTMLMailer Class)

This method sets the stream from which the class will read the HTML version of the message.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int SetMessageHTMLStream(IPWorksSSLStream* sMessageStream);

Unicode (Windows)
INT SetMessageHTMLStream(IPWorksSSLStream* sMessageStream);

int ipworksssl_htmlmailer_setmessagehtmlstream(void* lpObj, IPWorksSSLStream* sMessageStream);

int SetMessageHTMLStream(IPWorksSSLStream* sMessageStream);

Remarks

This method sets the stream from which the class will read the HTML version of the message. Once set, the class reads the content of the stream and populates the MessageHTML property with the HTML version of the message. The corresponding plaintext version is provided in the MessageText property.

When this property is called, the class automatically computes a plaintext version of the text and puts it into MessageText. You may choose to override this default text with your own version.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

ConnectionStatus Event (HTMLMailer Class)

This event is fired to indicate changes in the connection state.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireConnectionStatus(HTMLMailerConnectionStatusEventParams *e);

typedef struct {
  const char *ConnectionEvent;
  int StatusCode;
  const char *Description;
  int reserved;
} HTMLMailerConnectionStatusEventParams;


Unicode (Windows)
virtual INT FireConnectionStatus(HTMLMailerConnectionStatusEventParams *e);

typedef struct {
  LPCWSTR ConnectionEvent;
  INT StatusCode;
  LPCWSTR Description;
  INT reserved;
} HTMLMailerConnectionStatusEventParams;

#define EID_HTMLMAILER_CONNECTIONSTATUS 1

class HTMLMailerConnectionStatusEventParams {
public:
  const QString &ConnectionEvent();

  int StatusCode();

  const QString &Description();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void ConnectionStatus(HTMLMailerConnectionStatusEventParams *e);

// Or, subclass HTMLMailer and override this emitter function.
virtual int FireConnectionStatus(HTMLMailerConnectionStatusEventParams *e) {...}

Remarks

The ConnectionStatus 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:

EndTransfer Event (HTMLMailer Class)

This event is fired when the message text completes transferring.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireEndTransfer(HTMLMailerEndTransferEventParams *e);

typedef struct {
  int Direction;
  int reserved;
} HTMLMailerEndTransferEventParams;


Unicode (Windows)
virtual INT FireEndTransfer(HTMLMailerEndTransferEventParams *e);

typedef struct {
  INT Direction;
  INT reserved;
} HTMLMailerEndTransferEventParams;

#define EID_HTMLMAILER_ENDTRANSFER 2

virtual INT IPWORKSSSL_CALL FireEndTransfer(INT &iDirection);

class HTMLMailerEndTransferEventParams {
public:
  int Direction();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void EndTransfer(HTMLMailerEndTransferEventParams *e);

// Or, subclass HTMLMailer and override this emitter function.
virtual int FireEndTransfer(HTMLMailerEndTransferEventParams *e) {...}

Remarks

If MessageText is not empty, the EndTransfer event is fired when the MessageText finishes transferring from the local host to the MailServer. If MessageText is empty, the event is not fired.

If a file is attached to the MessageText via the AttachedFile property, then EndTransfer fires again when the file finishes transferring. For more information, go to the description of the AttachedFile property.

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

Error Event (HTMLMailer Class)

Information about errors during data delivery.

Syntax

};

// To handle, connect one or more slots to this signal.
void Error(HTMLMailerErrorEventParams *e);

// Or, subclass HTMLMailer and override this emitter function.
virtual int FireError(HTMLMailerErrorEventParams *e) {...}

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the class 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.

PITrail Event (HTMLMailer Class)

Traces the commands sent to the mail server, and the respective replies.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FirePITrail(HTMLMailerPITrailEventParams *e);

typedef struct {
  int Direction;
  const char *Message;
  int reserved;
} HTMLMailerPITrailEventParams;


Unicode (Windows)
virtual INT FirePITrail(HTMLMailerPITrailEventParams *e);

typedef struct {
  INT Direction;
  LPCWSTR Message;
  INT reserved;
} HTMLMailerPITrailEventParams;

#define EID_HTMLMAILER_PITRAIL 4

virtual INT IPWORKSSSL_CALL FirePITrail(INT &iDirection, LPSTR &lpszMessage);

class HTMLMailerPITrailEventParams {
public:
  int Direction();

  const QString &Message();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.

The PITrail event is useful for debugging purposes. It shows all the interaction between the client and the server, line by line, except for message header and body transfers.

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

SSLServerAuthentication Event (HTMLMailer Class)

Fired after the server presents its certificate to the client.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireSSLServerAuthentication(HTMLMailerSSLServerAuthenticationEventParams *e);

typedef struct {
  const char *CertEncoded;
  int lenCertEncoded;
  const char *CertSubject;
  const char *CertIssuer;
  const char *Status;
  int Accept;
  int reserved;
} HTMLMailerSSLServerAuthenticationEventParams;


Unicode (Windows)
virtual INT FireSSLServerAuthentication(HTMLMailerSSLServerAuthenticationEventParams *e);

typedef struct {
  LPCSTR CertEncoded;
  INT lenCertEncoded;
  LPCWSTR CertSubject;
  LPCWSTR CertIssuer;
  LPCWSTR Status;
  BOOL Accept;
  INT reserved;
} HTMLMailerSSLServerAuthenticationEventParams;

#define EID_HTMLMAILER_SSLSERVERAUTHENTICATION 5

virtual INT IPWORKSSSL_CALL FireSSLServerAuthentication(LPSTR &lpCertEncoded, INT &lenCertEncoded, LPSTR &lpszCertSubject, LPSTR &lpszCertIssuer, LPSTR &lpszStatus, BOOL &bAccept);

class HTMLMailerSSLServerAuthenticationEventParams {
public:
  const QByteArray &CertEncoded();

  const QString &CertSubject();

  const QString &CertIssuer();

  const QString &Status();

  bool Accept();
  void SetAccept(bool bAccept);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void SSLServerAuthentication(HTMLMailerSSLServerAuthenticationEventParams *e);

// Or, subclass HTMLMailer and override this emitter function.
virtual int FireSSLServerAuthentication(HTMLMailerSSLServerAuthenticationEventParams *e) {...}

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 (HTMLMailer Class)

Shows the progress of the secure connection.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireSSLStatus(HTMLMailerSSLStatusEventParams *e);

  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void StartTransfer(HTMLMailerStartTransferEventParams *e);

// Or, subclass HTMLMailer and override this emitter function.
virtual int FireStartTransfer(HTMLMailerStartTransferEventParams *e) {...}

Remarks

If MessageText is not empty, the StartTransfer event is fired when the MessageText starts transferring from the local host to the MailServer. If MessageText is empty, the event is not fired.

If a file is attached to the MessageText via the AttachedFile property, then StartTransfer fires again when the file starts transferring. Please go to the description of the AttachedFile property for more information.

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

Transfer Event (HTMLMailer Class)

Fired while the message text gets transferred to MailServer .

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireTransfer(HTMLMailerTransferEventParams *e);

typedef struct {
  int Direction;
  int64 BytesTransferred;
  int PercentDone;
  const char *Text;
  int lenText;
  int reserved;
} HTMLMailerTransferEventParams;


Unicode (Windows)
virtual INT FireTransfer(HTMLMailerTransferEventParams *e);

typedef struct {
  INT Direction;
  LONG64 BytesTransferred;
  INT PercentDone;
  LPCSTR Text;
  INT lenText;
  INT reserved;
} HTMLMailerTransferEventParams;

#define EID_HTMLMAILER_TRANSFER 8

virtual INT IPWORKSSSL_CALL FireTransfer(INT &iDirection, LONG64 &lBytesTransferred, INT &iPercentDone, LPSTR &lpText, INT &lenText);

class HTMLMailerTransferEventParams {
public:

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void Transfer(HTMLMailerTransferEventParams *e);

// Or, subclass HTMLMailer and override this emitter function.
virtual int FireTransfer(HTMLMailerTransferEventParams *e) {...}

Remarks

One or more Transfer events are fired during message delivery. Messages consist of MessageText and an optional AttachedFile. The BytesTransferred parameter shows the number of bytes sent starting from the beginning of MessageText and/or AttachedFile.

Text contains the current portion of the message being sent.

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.

IPWorksSSLStream Type

Syntax

IPWorksSSLStream (declared in ipworksssl.h)

Remarks

The HTMLMailer class includes one or more API members that take a stream object as a parameter. To use such API members, create a concrete class that implements the IPWorksSSLStream interface and pass the HTMLMailer class an instance of that concrete class.

When implementing the IPWorksSSLStream interface's properties and methods, they must behave as described below. If the concrete class's implementation does not behave as expected, undefined behavior may occur.

bool CanRead() { return true; }

bool CanSeek() { return true; }

bool CanWrite() { return true; }

int64 GetLength() = 0;

void Close() {}

int Flush() { return 0; }

int Read(void* buffer, int count) = 0;

int64 Seek(int64 offset, int seekOrigin) = 0;

int Write(const void* buffer, int count) = 0;
