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 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 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.

AuthMechanism Property (HTMLMailer Class)

This property is used when connecting to the mail server.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int GetAuthMechanism();
int SetAuthMechanism(int iAuthMechanism);

Unicode (Windows)
INT GetAuthMechanism();
INT SetAuthMechanism(INT iAuthMechanism);

AM_USER_PASSWORD(0), 
AM_CRAMMD5(1), 
AM_NTLM(2), 
AM_APOP(3), 
AM_SASLPLAIN(4), 
AM_SASLDIGEST_MD5(5), 
AM_KERBEROS(6), 
AM_XOAUTH2(7)

int ipworks_htmlmailer_getauthmechanism(void* lpObj);
int ipworks_htmlmailer_setauthmechanism(void* lpObj, int iAuthMechanism);

int GetAuthMechanism();
int SetAuthMechanism(int iAuthMechanism);

Default Value

0

Remarks

This is the authentication mechanism property to be used when connecting to the mail server.

By default, this property is amUserPassword (0), and if the User and Password properties are set, the AUTH command is sent to the server for authentication. If this property is set to amCRAMMD5 (1), CRAM-MD5 authentication is used instead.

If this property is set to amNTLM (2), NTLM authentication will be used.

If this property is set to amKerberos (6), Kerberos authentication will be used.

Note: This functionality is available only in Windows.

When set to amXOAUTH2 (7), set User to the username and AuthorizationIdentity to the OAuth token. See AuthorizationIdentity for details.

Data Type

Integer

BCc Property (HTMLMailer Class)

This property includes a comma-separated list of addresses for blind carbon copies (optional).

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* GetBCc();
int SetBCc(const char* lpszBCc);

Unicode (Windows)
LPWSTR GetBCc();
INT SetBCc(LPCWSTR lpszBCc);

char* ipworks_htmlmailer_getbcc(void* lpObj);
int ipworks_htmlmailer_setbcc(void* lpObj, const char* lpszBCc);

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

String

Cc Property (HTMLMailer Class)

This property includes a comma-separated list of addresses for carbon copies (optional).

Syntax

• C++
• C
• Qt

char* ipworks_htmlmailer_getcc(void* lpObj);
int ipworks_htmlmailer_setcc(void* lpObj, const char* lpszCc);

QString GetCc();
int SetCc(QString qsCc);

Default Value

""

Remarks

This property specifies a comma-separated list of destinations for carbon copies of the mail message. 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.

LocalHost Property (HTMLMailer Class)

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

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* GetLocalHost();
int SetLocalHost(const char* lpszLocalHost);

Unicode (Windows)
LPWSTR GetLocalHost();

int ipworks_htmlmailer_setlocalhost(void* lpObj, const char* lpszLocalHost);

QString GetLocalHost();
int SetLocalHost(QString qsLocalHost);

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 class initiate connections (or accept in the case of server classs) 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 class 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

MailPort Property (HTMLMailer Class)

This property includes the server port for SMTP (default 25).

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)

int SetMailPort(int iMailPort);

Default Value

25

Remarks

This property contains the server port for SMTP (default 25). 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 465 (please refer to the SSLStartMode property for more information).

This property is not available at design time.

Data Type

Integer

MailServer Property (HTMLMailer Class)

This property includes the name or address of a mail server (mail relay).

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* GetMailServer();
int SetMailServer(const char* lpszMailServer);

Unicode (Windows)
LPWSTR GetMailServer();
INT SetMailServer(LPCWSTR lpszMailServer);

char* ipworks_htmlmailer_getmailserver(void* lpObj);
int ipworks_htmlmailer_setmailserver(void* lpObj, const char* lpszMailServer);

QString GetMailServer();
int SetMailServer(QString qsMailServer);

Default Value

""

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 (e.g., a UNIX host), 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. 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.

Data Type

String

MessageDate Property (HTMLMailer Class)

This property includes the date of the mail message (optional).

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* GetMessageDate();

INT SetMessageDate(LPCWSTR lpszMessageDate);

char* ipworks_htmlmailer_getmessagedate(void* lpObj);
int ipworks_htmlmailer_setmessagedate(void* lpObj, const char* lpszMessageDate);

QString GetMessageDate();
int SetMessageDate(QString qsMessageDate);

Default Value

"*"

Remarks

If this property contains a nonempty string, then a Date SMTP header is created and attached to the message. If it is an empty string, then the date information is added by the mail relay(s) the message goes through.

Special case: If this property is set to the special value "*", a Date SMTP header reflecting the current date and time is generated when MessageHeaders is computed and the message is sent. This is the default behavior of the class

RFC 822 contains detailed date format specifications. An example of a valid date is "Fri, 1 Mar 96 21:24:52 EST".

This property is not available at design time.

Data Type

The headers must be of the format "header: value" as specified in RFC 822. Header lines should be separated by CRLF ("\r\n") .

Use this property with caution. If this property contains invalid headers, message delivery might not be successful.

This property is useful for extending the functionality of the class. A good example is delivery of MIME-encoded messages.

Special case: If this property starts with an empty line (CRLF), then the value of this property is used instead of the normally computed message headers.

Example. Sending an Email with an Additional Header:

component.MailServer = "MyServer"; component.From = "me@server.com"; component.SendTo = "recipient@server.com"; component.Subject = "My Subject"; component.MessageText = "This is the message body."; component.OtherHeaders = "HeaderName: HeaderValue"; component.Send();

QByteArray GetSSLAcceptServerCertEncoded();
int SetSSLAcceptServerCertEncoded(QByteArray qbaSSLAcceptServerCertEncoded);

Remarks

If it finds any issues with the certificate presented by the server, the class will normally terminate the connection with an error.

You may override this behavior by supplying a value for SSLAcceptServerCert. If the certificate supplied in SSLAcceptServerCert is the same as the certificate presented by the server, then the server certificate is accepted unconditionally, and the connection will continue normally.

Note: This functionality is provided only for cases in which you otherwise know that you are communicating with the right server. If used improperly, this property may create a security breach. Use it at your own risk.

Default Value

0

Remarks

This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic), the class will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.

Possible values are as follows:

In most cases using the default value (Automatic) is recommended. The class will select a provider depending on the current platform.

When Automatic is selected, on Windows, the class will use the platform implementation. On Linux/macOS, the class will use the internal implementation. When TLS 1.3 is enabled via SSLEnabledProtocols, the internal implementation is used on all platforms.

Subject Property (HTMLMailer Class)

This property includes 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();

Data Type

String

Timeout Property (HTMLMailer Class)

The 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 ipworks_htmlmailer_gettimeout(void* lpObj);
int ipworks_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.

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

User Property (HTMLMailer Class)

This property includes the user identifier needed to log in as in the MailServer .

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)

Remarks

If this property is set to a nonempty string, then when connecting to the MailServer an AUTH or CRAM-MD5 (depending on the value of AuthMechanism) command is sent 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 ipworks_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 ipworks_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* ipworks_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 ipworks_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 ipworks_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)

This method processes events from the internal message queue.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int DoEvents();

Unicode (Windows)
INT DoEvents();

int ipworks_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)

This method interrupts the current method.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int Interrupt();

Unicode (Windows)
INT Interrupt();

int ipworks_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)

This method sends the messages that previously have been queued into QueueDir .

Syntax

• C++
• C
• Qt

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

Unicode (Windows)
INT ProcessQueue(LPCWSTR lpszQueueDir);

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

int ProcessQueue(const QString& qsQueueDir);

Remarks

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

This method looks in the directory for files with the 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)

This method queues the message into QueueDir .

Syntax

• C++
• C
• Qt

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

Unicode (Windows)
LPWSTR Queue(LPCWSTR lpszQueueDir);

char* ipworks_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.

This 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)

This method will reset the class.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int Reset();

Unicode (Windows)
INT Reset();

int ipworks_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)

This method resets all the message headers to empty.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int ResetHeaders();

Unicode (Windows)
INT ResetHeaders();

int ipworks_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 ipworks_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)

This method 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 ipworks_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 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(IPWorksStream* sMessageStream);

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

int ipworks_htmlmailer_setmessagehtmlstream(void* lpObj, IPWorksStream* sMessageStream);

int SetMessageHTMLStream(IPWorksStream* 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)

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

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:

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 IPWORKS_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)

Fired when information is available about errors during data delivery.

Syntax

• C++

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

// 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)

This event 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 IPWORKS_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.
void PITrail(HTMLMailerPITrailEventParams *e);

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

Remarks

The PITrail event is useful for debugging purposes. It shows all of 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 IPWORKS_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)

Fired when secure connection progress messages are available.

Syntax

• C++

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

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

Remarks

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

StartTransfer Event (HTMLMailer Class)

This event is fired when the message text starts transferring.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireStartTransfer(HTMLMailerStartTransferEventParams *e);

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

virtual INT FireStartTransfer(HTMLMailerStartTransferEventParams *e);

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

#define EID_HTMLMAILER_STARTTRANSFER 7

virtual INT IPWORKS_CALL FireStartTransfer(INT &iDirection);

class HTMLMailerStartTransferEventParams {
public:
  int Direction();

  int EventRetVal();
  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)

This event is fired when the message text is 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 IPWORKS_CALL FireTransfer(INT &iDirection, LONG64 &lBytesTransferred, INT &iPercentDone, LPSTR &lpText, INT &lenText);

class HTMLMailerTransferEventParams {
public:
  int Direction();

  qint64 BytesTransferred();

  int PercentDone();

  const QByteArray &Text();

  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 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.
