TChilkatEmail Delphi ActiveX Reference Documentation

TChilkatEmail

Current Version: 9.5.0.73

Represents a complete Email object.

Importing the Chilkat ActiveX into Delphi

Important: When upgrading to a new version of Chilkat, make sure to re-imported ActiveX DLL into Delphi to regenerate the files described below.

Two things are required to use an ActiveX in Delphi:

  1. The ActiveX DLL needs to be registered via regsvr32 on the system where the Delphi application runs. See How To Register ActiveX DLLs for detailed information.
  2. See also: ActiveX Registration Tutorial
  3. The ActiveX component needs to be "imported". Use the Delphi Import Component Wizard to import the Chilkat type library. This creates the following files: Chilkat_v9_5_0_TLB.pas and Chilkat_v9_5_0_TLB.dcr. The Chilkat_v9_5_0_TLB.pas should be added to your project.

To import the Chilkat type library, do the following:

  1. In the Delphi RAD Studio, select the menu item "Component" --> "Import a Type Library".
  2. Find "Chilkat ActiveX v9.5.0" in the list and select it. This will only appear in the list if the ChilkatAx-9.5.0-win32.dll (or ChilkatAx-9.5.0-x64.dll) has been registered w/ regsvr32.
  3. Check the "Generate Component Wrappers" checkbox.
  4. Select a directory where the unit files (.pas and .dcr) should be generated.
  5. Select "Create Unit" and then "Finish".
  6. Add the .pas to your Delphi project.

To use a Chilkat ActiveX object in your Delphi code, add "Chilkat_v9_5_0_TLB" to the "uses" statement. For example:

uses
  Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
  Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls, Chilkat_v9_5_0_TLB;

Object Creation

var
obj: TChilkatEmail;
...
begin
obj := TChilkatEmail.Create(Self);
...
// When finished, free the object instance.
obj.Free();

Properties

Body
property Body: WideString

The body of the email. If the email has both HTML and plain-text bodies, this property returns the HTML body. The GetHtmlBody and GetPlainTextBody methods can be used to access a specific body. The HasHtmlBody and HasPlainTextBody methods can be used to determine the presence of a body.

top
BounceAddress
property BounceAddress: WideString

The "return-path" address of the email to be used when the email is sent. Bounces (i.e. delivery status notifications, or DSN's) will go to this address.

Note: This is not the content of the "return-path" header for emails that are downloaded from a POP3 or IMAP server. The BounceAddress is the email address to be used in the process of sending the email via SMTP. (See the "SMTP Protocol in a Nutshell" link below.) The BounceAddress is the email address passed in the "MAIL FROM" SMTP command which becomes the "return-path" header in the email when received.

Note: The Sender and BounceAddress properties are identical and perform the same function. Setting the Sender property also sets the BounceAddress property, and vice-versa. The reason for the duplication is that BounceAddress existed first, and developers typically searched for a "Sender" property without realizing that the BounceAddress property served this function.

More Information and Examples
top
Charset
property Charset: WideString

Sets the charset for the entire email. The header fields and plain-text/HTML bodies will be converted and sent in this charset. (This includes parsing and updating the HTML with the appropriate META tag specifying the charset.) All formatting and encoding of the email MIME is handled automatically by the Chilkat Mail component. If your application wants to send a Shift_JIS email, you simply set the Charset property to "Shift_JIS". Note: If a charset property is not explicitly set, the Chilkat component automatically detects the charset and chooses the appropriate charset. If all characters are 7bit (i.e. us-ascii) the charset is left blank. If the email contain a mix of languages such that no one charset can be chosen, or if the language cannot be determined without ambiguity, then the "utf-8" charset will be chosen.

More Information and Examples
top
DebugLogFilePath
property DebugLogFilePath: WideString

If set to a file path, causes each Chilkat method or property call to automatically append it's LastErrorText to the specified log file. The information is appended such that if a hang or crash occurs, it is possible to see the context in which the problem occurred, as well as a history of all Chilkat calls up to the point of the problem. The VerboseLogging property can be set to provide more detailed information.

This property is typically used for debugging the rare cases where a Chilkat method call hangs or generates an exception that halts program execution (i.e. crashes). A hang or crash should generally never happen. The typical causes of a hang are:

  1. a timeout related property was set to 0 to explicitly indicate that an infinite timeout is desired,
  2. the hang is actually a hang within an event callback (i.e. it is a hang within the application code), or
  3. there is an internal problem (bug) in the Chilkat code that causes the hang.

top
Decrypted
property Decrypted: Integer readonly

1 if the email arrived encrypted and was successfully decrypted, otherwise 0.

top
EmailDateStr
property EmailDateStr: WideString

The date/time from the "Date" header in the UTC/GMT timezone in RFC822 string form.

top
EncryptedBy
property EncryptedBy: WideString readonly

If the email was received encrypted, this contains the details of the certificate used for encryption.

top
FileDistList
property FileDistList: WideString

Set this property to send an email to a list of recipients stored in a plain text file. The file format is simple: one recipient per line, no comments allowed, blank lines are ignored.Setting this property is equivalent to adding a "CKX-FileDistList"header field to the email. Chilkat Mail treats header fields beginning with "CKX-"specially in that these fields are never transmitted with the email when sent. However, CKX fields are saved and restored when saving to XML or loading from XML (or MIME). When sending an email containing a "CKX-FileDistList"header field, Chilkat Mail will read the distribution list file and send the email to each recipient. Emails can be sent individually, or with BCC, 100 recipients at a time. (see the MailMan.SendIndividual property).

top
From
property From: WideString

The combined name and email address of the sender, such as "John Smith" . This is the content that will be placed in the From: header field. If the actual sender is to be different, then set the Sender property to a different email address.

top
FromAddress
property FromAddress: WideString

The email address of the sender.

top
FromName
property FromName: WideString

The name of the sender.

top
Header
property Header: WideString readonly

The complete MIME header of the email.

top
Language
property Language: WideString readonly

A read-only property that identifies the primary language group for the email. Possible values are:

  • "latin1" (for English and all Western European languages)
  • "central" (for Central European languages such as Polish, Czech, Hungarian, etc.)
  • "russian" (for Cyrillic languages)
  • "greek"
  • "turkish"
  • "hebrew"
  • "arabic"
  • "thai"
  • "vietnamese"
  • "chinese"
  • "japanese"
  • "korean"
  • "devanagari"
  • "bengali"
  • "gurmukhi"
  • "gujarati"
  • "oriya"
  • "tamil"
  • "telugu"
  • "kannada"
  • "malayalam"
  • "sinhala"
  • "lao"
  • "tibetan"
  • "myanmar"
  • "georgian"
  • "unknown"
The language group determination is made soley on the subject and plain-text/HTML email bodies. Characters in the FROM, TO, CC, and other header fields are not considered.

The primary determining factor is the characters found in the Subject header field. For example, if an email contains Japanese in the Subject, but the body contains Russian characters, it will be considered "japanese".

The language is determined by where the Unicode chars fall in various blocks in the Unicode Basic Multilingual Plane. For more information, see the book "Unicode Demystified" by Richard Gillam.

top
LastBinaryResult
property LastBinaryResult: OleVariant readonly
Introduced in version 9.5.0.52

The binary data returned by the last (binary data returning) method called. Only available if Chilkat.Global.KeepBinaryResult is set to 1. This provides a means for obtaining large varbinary results in the SQL Server environment (where limitations exist in getting large amounts of data returned by method calls, but where temp tables can be used for binary properties).

top
LastErrorHtml
property LastErrorHtml: WideString readonly

Provides information in HTML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastErrorText
property LastErrorText: WideString readonly

Provides information in plain-text format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastErrorXml
property LastErrorXml: WideString readonly

Provides information in XML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastMethodSuccess
property LastMethodSuccess: Integer
Introduced in version 9.5.0.52

Indicate whether the last method call succeeded or failed. A value of 1 indicates success, a value of 0 indicates failure. This property is automatically set for method calls. It is not modified by property accesses. The property is automatically set to indicate success for the following types of method calls:

  • Any method that returns a string.
  • Any method returning a Chilkat object, binary bytes, or a date/time.
  • Any method returning a standard boolean status value where success = 1 and failure = 0.
  • Any method returning an integer where failure is defined by a return value less than zero.

Note: Methods that do not fit the above requirements will always set this property equal to 1. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

top
LastStringResult
property LastStringResult: WideString readonly
Introduced in version 9.5.0.52

The string return value of the last (string returning) method called. Only available if Chilkat.Global.KeepStringResult is set to 1. This provides a means for obtaining large string results in the SQL Server environment (where limitations exist in getting long strings returned by method calls, but where temp tables can be used for string properties).

top
LastStringResultLen
property LastStringResultLen: Integer readonly
Introduced in version 9.5.0.53

The length, in characters, of the string contained in the LastStringResult property.

top
LocalDateStr
property LocalDateStr: WideString

The date/time found in the "Date" header field returned in the local timezone in RFC822 string form.

top
Mailer
property Mailer: WideString

Identifies the email software that sent the email.

top
NumAlternatives
property NumAlternatives: Integer readonly

The number of alternative bodies present in the email. An email that is not "multipart/alternative"will return 0 alternatives. An email that is "multipart/alternative" will return a number greater than or equal to 1.

top
NumAttachedMessages
property NumAttachedMessages: Integer readonly

Returns the number of embedded emails. Some mail clients will embed an email that is to be forwarded into a new email as a "message/rfc822" subpart of the MIME message structure. This property tells how many emails have been embedded. The original email can be retrieved by calling GetAttachedMessage.

top
NumAttachments
property NumAttachments: Integer readonly

The number of attachments contained in the email.

Note: If an email is downloaded from an IMAP server without attachments, then the number of attachments should be obtained by calling the IMAP object's GetMailNumAttach method. This property indicates the actual number of attachments already present within the email object.

top
NumBcc
property NumBcc: Integer readonly

The number of blind carbon-copy email recipients.

More Information and Examples
top
NumCC
property NumCC: Integer readonly

The number of carbon-copy email recipients.

More Information and Examples
top
NumDaysOld
property NumDaysOld: Integer readonly

Returns the number of days old from the current system date/time. The email's date is obtained from the "Date" header field. If the Date header field is missing, or invalid, then -9999 is returned. A negative number may be returned if the Date header field contains a future date/time. (However, -9999 represents an error condition.)

top
NumDigests
property NumDigests: Integer readonly
Introduced in version 9.5.0.66

Returns the number of message/rfc822 parts contained within the multipart/digest enclosure. If no multipart/digest enclosure exists, then this property has the value of 0. The GetDigest method is called to get the Nth digest as an email object.

More Information and Examples
top
NumHeaderFields
property NumHeaderFields: Integer readonly

The number of header fields. When accessing a header field by index, the 1st header field is at index 0, and the last is at NumHeaderFields-1. (Chilkat indexing is always 0-based.)

top
NumRelatedItems
property NumRelatedItems: Integer readonly

The number of related items present in this email. Related items are typically image files (JPEGs or GIFs) or style sheets (CSS files) that are included with HTML formatted messages with internal "CID"hyperlinks.

top
NumReplacePatterns
property NumReplacePatterns: Integer readonly

Returns the number of replacement patterns previously set by calling the SetReplacePattern method 1 or more times. If replacement patterns are set, the email bodies and header fields are modified by applying the search/replacement strings during the message sending process.

top
NumReports
property NumReports: Integer readonly

(For multipart/report emails that have sub-parts with Content-Types such as message/feedback-report.) Any MIME sub-part within the email that has a Content-Type of "message/*", but is not a "message/rfc822", is considered to be a "report" and is included in this count. (A "message/rfc822" is considered an attached message and is handled by the NumAttachedMessages property and the GetAttachedMessage method.) Any MIME sub-part having a Content-Type equal to "text/rfc822-headers" is also considered to be a "report". The GetReport method may be called to get the body content of each "report" contained within a multipart/report email.

top
NumTo
property NumTo: Integer readonly

The number of direct email recipients.

More Information and Examples
top
OaepHash
property OaepHash: WideString
Introduced in version 9.5.0.67

Selects the hash algorithm for use within OAEP padding when encrypting email using RSAES-OAEP. The valid choices are "sha1", "sha256", "sha384", "sha512",

top
OaepMgfHash
property OaepMgfHash: WideString
Introduced in version 9.5.0.71

Selects the MGF hash algorithm for use within OAEP padding when encrypting email using RSAES-OAEP. The valid choices are "sha1", "sha256", "sha384", "sha512",

top
OaepPadding
property OaepPadding: Integer
Introduced in version 9.5.0.67

Selects the RSA encryption scheme when encrypting email. The default value is 0, which selects RSAES_PKCS1-V1_5. If set to 1, then RSAES_OAEP is used.

top
OverwriteExisting
property OverwriteExisting: Integer

When 1 (the default) the methods to save email attachments and related items will overwrite files if they already exist. If 0, then the methods that save email attachments and related items will append a string of 4 characters to create a unique filename if a file already exists. The filename of the attachment (or related item) within the email object is updated and can be retrieved by the program to determine the actual file(s) created.

top
Pkcs7CryptAlg
property Pkcs7CryptAlg: WideString

When an email is sent encrypted (using PKCS7 public-key encryption), this selects the underlying symmetric encryption algorithm. Possible values are: "aes", "des", "3des", and "rc2". The default value is "aes".

top
Pkcs7KeyLength
property Pkcs7KeyLength: Integer

When the email is sent encrypted (using PKCS7 public-key encryption), this selects the key length of the underlying symmetric encryption algorithm. The possible values allowed depend on the Pkcs7CryptAlg property. For "aes", the key length may be 128, 192, or 256. For "3des" the key length must be 192. For "des" the key length must be 40. For "rc2" the key length can be 40, 56, 64, or 128.

top
PreferredCharset
property PreferredCharset: WideString

Only applies when building an email with non-English characters where the charset is not explicitly set. The Chilkat email component will automatically choose a charset based on the languages found within an email (if the charset is not already specified within the MIME or explicitly specified by setting the Charset property). The default charset chosen for each language is:

Chinese: gb2312
Japanese: shift_JIS
Korean: ks_c_5601-1987
Thai: windows-874
All others: iso-8859-*

This allows for charsets such as iso-2022-jp to be chosen instead of the default. If the preferred charset does not apply to the situation, it is not used. For example, if the preferred charset is iso-2022-jp, but the email contains Greek characters, then the preferred charset is ignored.

More Information and Examples
top
PrependHeaders
property PrependHeaders: Integer

If 1, then header fields added via the AddHeaderField or AddHeaderField2 methods are prepended to the top of the header as opposed to appended to the bottom. The default value is 0.

top
ReceivedEncrypted
property ReceivedEncrypted: Integer readonly

1 if this email was originally received with encryption, otherwise 0.

top
ReceivedSigned
property ReceivedSigned: Integer readonly

1 if this email was originally received with a digital signature, otherwise 0.

More Information and Examples
top
ReplyTo
property ReplyTo: WideString

Sets the "Reply-To" header field to the specified email address.

top
ReturnReceipt
property ReturnReceipt: Integer

Set to 1 if you want the email to request a return-receipt when received by the recipient. The default value is 0.

top
SendEncrypted
property SendEncrypted: Integer

Set to 1 if this email should be sent encrypted.

top
Sender
property Sender: WideString
Introduced in version 9.5.0.41

The sender's address for this email message.

This is the address of the actual sender acting on behalf of the author listed in the From: field.

Note: The Sender and BounceAddress properties are identical and perform the same function. Setting the Sender property also sets the BounceAddress property, and vice-versa. The reason for the duplication is that BounceAddress existed first, and developers typically searched for a "Sender" property without realizing that the BounceAddress property served this function.

Important Note: This property does not contain the value of the "Sender" header field, if one exists, for a received email. It is a property that is used when sending email. To get the value of the "Sender" header field (which may not always exist), call the GetHeaderField method instead.

More Information and Examples
top
SendSigned
property SendSigned: Integer

Set to 1 if this email should be sent with a digital signature.

top
SignaturesValid
property SignaturesValid: Integer readonly

1 if the email was received with one or more digital signatures, and if all the signatures were validated indicating that the email was not altered. Otherwise this property is set to 0.

More Information and Examples
top
SignedBy
property SignedBy: WideString readonly

If the email was received digitally signed, this property contains the fields of the cert's SubjectDN.

For example: US, 60187, Illinois, Wheaton, 1719 E Forest Ave, "Chilkat Software, Inc.", "Chilkat Software, Inc."

It is like the DN (Distinguished Name), but without the "AttrName=" before each attribute.

top
SigningAlg
property SigningAlg: WideString
Introduced in version 9.5.0.67

Selects the signature algorithm to be used when sending signed (PKCS7) email. The default value is "PKCS1-v1_5". This can be set to "RSASSA-PSS" (or simply "pss") to use the RSASSA-PSS signature scheme.

Note: This property only applies when signing with an RSA private key. It does not apply for ECC or DSA private keys.

top
SigningHashAlg
property SigningHashAlg: WideString

Selects the underlying hash algorithm used when sending signed (PKCS7) email. Possible values are "sha1", "sha256", "sha384", "sha512", "md5", and "md2".

top
Size
property Size: Integer readonly

The size in bytes of the email, including all parts and attachments.

top
Subject
property Subject: WideString

The email subject.

top
Uidl
property Uidl: WideString readonly

This is the unique ID assigned by the POP3 server. Emails can be retrieved or deleted from the POP3 server via the UIDL. The header field for this property is "X-UIDL".

Important: Emails downloaded via the IMAP protocol do not have UIDL's. UIDL's are specific to the POP3 protocol. IMAP servers use UID's (notice the spelling difference -- "UIDL" vs. "UID"). An email downloaded via the Chilkat IMAP component will contain a "ckx-imap-uid" header field that contains the UID. This may be accessed via the GetHeaderField method.

top
UnpackUseRelPaths
property UnpackUseRelPaths: Integer

Applies to the UnpackHtml method. If 1, then relative paths are used within the HTML for the links to the related files (images and style sheets) that were unpacked to the filesystem. Otherwise absolute paths are used. The default value is 1.

top
VerboseLogging
property VerboseLogging: Integer

If set to 1, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is 0. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

top
Version
property Version: WideString readonly

Version of the component/library, such as "9.5.0.63"

top

Methods

AddAttachmentBd
function AddAttachmentBd(filename: WideString; binData: TChilkatBinData; contentType: WideString): Integer;
Introduced in version 9.5.0.63

Adds an attachment using the contents of a BinData object. If contentType is empty, then the content-type will be inferred from the filename extension.

Returns 1 for success, 0 for failure.

More Information and Examples
top
AddAttachmentHeader
procedure AddAttachmentHeader(index: Integer; fieldName: WideString; fieldValue: WideString);

Adds or replaces a MIME header field in one of the email attachments. If the header field does not exist, it is added. Otherwise it is replaced.

top
AddBcc
function AddBcc(friendlyName: WideString; emailAddress: WideString): Integer;

Adds a recipient to the blind carbon-copy list. address is required, but name may be empty.

Returns 1 for success, 0 for failure.

top
AddCC
function AddCC(friendlyName: WideString; emailAddress: WideString): Integer;

Adds a recipient to the carbon-copy list. address is required, but name may be empty.

Returns 1 for success, 0 for failure.

top
AddDataAttachment
function AddDataAttachment(fileName: WideString; content: OleVariant): Integer;

Adds an attachment directly from data in memory to the email.

Returns 1 for success, 0 for failure.

top
AddDataAttachment2
function AddDataAttachment2(fileName: WideString; content: OleVariant; contentType: WideString): Integer;

Adds an attachment to an email from in-memory data. Same as AddDataAttachment but allows the content-type to be specified.

Returns 1 for success, 0 for failure.

top
AddEncryptCert
function AddEncryptCert(cert: TChilkatCert): Integer;

Allows for certificates to be explicitly specified for sending encrypted email to one or more recipients. Call this method once per certificate to be used. The ClearEncryptCerts method may be called to clear the list of explicitly-specified certificates.

Note: It is possible to send encrypted email without explicitly specifying the certificates. On Windows computers, the registry-based Current-User and Local-Machine certificate stores are automatically searched for certs matching each of the recipients (To, CC, and BCC recipients).

Note: The SetEncryptCert method is equivalent to calling ClearEncryptCerts followed by AddEncryptCert.

Returns 1 for success, 0 for failure.

top
AddFileAttachment
function AddFileAttachment(path: WideString): WideString;

Adds a file as an attachment to the email. Returns the MIME content-type of the attachment, which is inferred based on the filename extension.

Returns a zero-length WideString on failure

More Information and Examples
top
AddFileAttachment2
function AddFileAttachment2(path: WideString; contentType: WideString): Integer;

Same as AddFileAttachment, but the content type can be explicitly specified.

Returns 1 for success, 0 for failure.

More Information and Examples
top
AddHeaderField
procedure AddHeaderField(fieldName: WideString; fieldValue: WideString);

Any standard or non-standard (custom) header field can be added to the email with this method. One interesting feature is that all header fields whose name begins with "CKX-" will not be included in the header when an email is sent. These fields will be included when saved to or loaded from XML. This makes it easy to include persistent meta-data with an email which your programs can use in any way it chooses.

Important: This method will replace an already-existing header field. To allow for adding duplicate header fields, call AddHeaderField2 (see below).

top
AddHeaderField2
procedure AddHeaderField2(fieldName: WideString; fieldValue: WideString);

This method is the same as AddHeaderField, except that if the header field already exists, it is not replaced. A duplicate header will be added.

top
AddHtmlAlternativeBody
function AddHtmlAlternativeBody(body: WideString): Integer;

Sets the HTML body of the email. Use this method if there will be multiple versions of the body, but in different formats, such as HTML and plain text. Otherwise, set the body by calling the SetHtmlBody method.

Returns 1 for success, 0 for failure.

More Information and Examples
top
AddiCalendarAlternativeBody
function AddiCalendarAlternativeBody(icalContent: WideString; methodName: WideString): Integer;

Adds an iCalendar (text/calendar) alternative body to the email. The icalContent contains the content of the iCalendar data. A sample is shown here:

BEGIN:VCALENDAR
VERSION:2.0
PRODID:-//hacksw/handcal//NONSGML v1.0//EN
BEGIN:VEVENT
UID:uid1@example.com
DTSTAMP:19970714T170000Z
ORGANIZER;CN=John Doe:MAILTO:john.doe@example.com
DTSTART:19970714T170000Z
DTEND:19970715T035959Z
SUMMARY:Bastille Day Party
END:VEVENT
END:VCALENDAR
The methodName is the "method" attribute used in the Content-Type header field in the alternative body. For example, if set to "REQUEST", then the alternative body's header would look like this:
Content-Type: text/calendar; method=REQUEST
Content-Transfer-Encoding: base64

Returns 1 for success, 0 for failure.

top
AddMultipleBcc
function AddMultipleBcc(commaSeparatedAddresses: WideString): Integer;

Adds multiple recipients to the blind carbon-copy list. The parameter is a string containing a comma separated list of full email addresses. Returns True if successful.

Returns 1 for success, 0 for failure.

top
AddMultipleCC
function AddMultipleCC(commaSeparatedAddresses: WideString): Integer;

Adds multiple recipients to the carbon-copy list. The parameter is a string containing a comma separated list of full email addresses. Returns True if successful.

Returns 1 for success, 0 for failure.

top
AddMultipleTo
function AddMultipleTo(commaSeparatedAddresses: WideString): Integer;

Adds multiple recipients to the "to" list. The parameter is a string containing a comma separated list of full email addresses. Returns True if successful.

Returns 1 for success, 0 for failure.

top
AddPfxSourceData
function AddPfxSourceData(pfxBytes: OleVariant; pfxPassword: WideString): Integer;

Adds a PFX to the object's internal list of sources to be searched for certificates and private keys when decrypting. Multiple PFX sources can be added by calling this method once for each. (On the Windows operating system, the registry-based certificate stores are also automatically searched, so it is commonly not required to explicitly add PFX sources.)

The pfxBytes contains the bytes of a PFX file (also known as PKCS12 or .p12).

Returns 1 for success, 0 for failure.

top
AddPfxSourceFile
function AddPfxSourceFile(pfxFilePath: WideString; pfxPassword: WideString): Integer;

Adds a PFX file to the object's internal list of sources to be searched for certificates and private keys when decrypting. Multiple PFX files can be added by calling this method once for each. (On the Windows operating system, the registry-based certificate stores are also automatically searched, so it is commonly not required to explicitly add PFX sources.)

The pfxFilePath contains the bytes of a PFX file (also known as PKCS12 or .p12).

Returns 1 for success, 0 for failure.

top
AddPlainTextAlternativeBody
function AddPlainTextAlternativeBody(body: WideString): Integer;

Sets the plain-text body of the email. Use this method if there will be multiple versions of the body, but in different formats, such as HTML and plain text. Otherwise, simply set the Body property.

Returns 1 for success, 0 for failure.

AddRelatedBd
function AddRelatedBd(filename: WideString; binData: TChilkatBinData): WideString;
Introduced in version 9.5.0.65

Adds a related item using the contents of a BinData object. Returns the Content-ID for the newly added relted item.

Returns a zero-length WideString on failure

More Information and Examples
top
AddRelatedBd2
function AddRelatedBd2(binData: TChilkatBinData; fileNameInHtml: WideString): Integer;
Introduced in version 9.5.0.65

Adds a related item using the contents of a BinData object. The fileNameInHtml should be set to the filename/path/url used in the corresponding HTML IMG tag's "src" attribute.

Returns 1 for success, 0 for failure.

top
AddRelatedData
function AddRelatedData(fileName: WideString; inData: OleVariant): WideString;

Adds the memory data as a related item to the email and returns the Content-ID. Emails formatted in HTML can include images with this call and internally reference the image through a "cid"hyperlink. (Chilkat Email.NET fully supports the MHTML standard.)

Returns a zero-length WideString on failure

top
AddRelatedData2
procedure AddRelatedData2(inData: OleVariant; fileNameInHtml: WideString);

Adds a related item to the email from in-memory byte data. Related items are things such as images and style sheets that are embedded within an HTML email. They are not considered attachments because their sole purpose is to participate in the display of the HTML. This method differs from AddRelatedData in that it does not use or return a Content-ID. The filename argument should be set to the filename used in the HTML img tag's src attribute (if it's an image), or the URL referenced in an HTML link tag for a stylesheet.

top
AddRelatedFile
function AddRelatedFile(path: WideString): WideString;

Adds the contents of a file to the email and returns the Content-ID. Emails formatted in HTML can include images with this call and internally reference the image through a "cid" hyperlink. (Chilkat Email.NET fully supports the MHTML standard.)

Returns a zero-length WideString on failure

top
AddRelatedFile2
function AddRelatedFile2(filenameOnDisk: WideString; filenameInHtml: WideString): Integer;

Adds a related item to the email from a file. Related items are things such as images and style sheets that are embedded within an HTML email. They are not considered attachments because their sole purpose is to participate in the display of the HTML. This method differs from AddRelatedFile in that it does not use or return a Content-ID. The filenameInHtml argument should be set to the filename used in the HTML img tag's src attribute (if it's an image), or the URL referenced in an HTML link tag for a stylesheet. The filenameOnDisk is the path in the local filesystem of the file to be added.

Note: Outlook.com will not properly display embedded HTMl images when the filenameInHtml includes a path part. Apparently, Outlook.com is only capable of correctly displaying images when the filenameInHtml is a only a filename. Other email clients, such as Mozilla Thunderbird, have no trouble when the filenameInHtml includes a path part.

Returns 1 for success, 0 for failure.

top
AddRelatedHeader

top
AddRelatedString2
procedure AddRelatedString2(fileNameInHtml: WideString; content: WideString; charset: WideString);

Adds a related item to the email from an in-memory string. Related items are things such as images and style sheets that are embedded within an HTML email. They are not considered attachments because their sole purpose is to participate in the display of the HTML. The filenameInHtml argument should be set to the filename used in the HTML img tag's src attribute (if it's an image), or the URL referenced in an HTML link tag for a stylesheet. The charset argument indicates that the content should first be converted to the specified charset prior to adding to the email. It should hava a value such as "iso-8859-1", "utf-8", "Shift_JIS", etc.

AesEncrypt
function AesEncrypt(password: WideString): Integer;

Encrypts the email body, all alternative bodies, all message sub-parts and attachments using 128-bit AES CBC encryption. Decrypting is achieved by calling AesDecrypt with the same password. The AesEncrypt/Decrypt methods use symmetric password-based AES encryption and greatly simplify sending and receiving encrypted emails because certificates and private keys are not used. However, the sending and receiving applications must both use Chilkat, and the password must be pre-known on both ends.

Returns 1 for success, 0 for failure.

ComputeGlobalKey2
function ComputeGlobalKey2(encoding: WideString; bFold: Integer): WideString;
Introduced in version 9.5.0.59

Computes a global unique key for the email. The key is created by a digest-MD5 hash of the concatenation of the following:

messageID + CRLF + subject + CRLF + from + CRLF + date + CRLF + recipientAddrs

messageID contains the contents of the Message-ID header field.
subject contains the contents of the Subject header field, trimmed of whitespace from both ends, 
    where TAB chars are converted to SPACE chars, and internal whitespace is trimmed so that 
   no more than one SPACE char in a row exists.
from contains the lowercase FROM header email address.
date contains the contents of the DATE header field.
toAddrs contains lowercase TO and CC recipient email addresses, comma separated, with duplicates removed, and sorted 
    in ascending order.  The BCC addresses are NOT included.

(After calling this method, the LastErrorText property can be examined to see the string that was hashed.)
The 16-byte MD5 hash is returned as an encoded string. The encoding determines the encoding: base64, hex, url, etc. If bFold is 1, then the 16-byte MD5 hash is folded to 8 bytes with an XOR to produce a shorter key.

FindIssuer
function FindIssuer(cert: TChilkatCert): TChilkatCert;

Digitally signed and/or encrypted emails are automatically "unwrapped" when received from a POP3 or IMAP server, or when loaded from any source such as a MIME string, in-memory byte data, or a .eml file. The results of the signature verification / decryption are stored in the properties such as ReceivedSigned, ReceivedEncrypted, SignaturesValid, etc. The signing certificate can be obtained via the GetSigningCert function. If the signature contained more certificates in the chain of authentication, this method provides a means to access them.

During signature verification, the email object collects the certs found in the signature and holds onto them internally. To get the issuing certificate of the signing certificate, call this method passing the cert returned by GetSigningCert. If the issuing cert is available, it is returned. Otherwise nil is returned. If the cert passed in is the root (i.e. a self-signed certificate), then the cert object returned is a copy of the cert passed in.

To traverse the chain to the root, one would write a loop that on first iteration passes the cert returned by GetSignedByCert (not GetSignerCert), and then on each subsequent iteration passes the cert from the previous iteration. The loop would exit when a cert is returned that has the same SubjectDN and SerialNumber as what was passed in (or when FindIssuer returns nil).

Returns nil on failure

GetImapUid
function GetImapUid(): Integer;

When email headers are downloaded from an IMAP server (using Chilkat IMAP), a "ckx-imap-uid" header field is added. The content of this header is the UID or sequence number of the email on the IMAP server. In addition, a "ckx-imap-isUid" header field is added, and this will have the value YES or NO. If the value is YES, then ckx-imap-uid contains a UID, if the value is NO, then ckx-imap-uid contains the sequence number. This method returns the UID if ckx-imap-uid exists and contains a UID, otherwise it returns -1.

An application that wishes to download the full email would use this UID and then call the Chilkat IMAP object's FetchSingle or FetchSingleAsMime methods.

Note:If an email was downloaded from the IMAP server in a way such that the UID is not received, then there will be no "ckx-imap-uid" header field and this method would return -1. For example, if emails are downloaded by sequence numbers via the Imap.FetchSequence method, then UIDs are not used and therefore the email object will not contain this information.
