ChilkatMime ActiveX Reference

ChilkatMime

Chilkat MIME allows you to easily create and manipulate MIME and S/MIME messages from within your applications.

Properties

Boundary As String

The boundary string to be used if this is a multipart message. By default, the boundary is automatically generated to be a unique and random string, so explicitly setting the boundary is not necessary.

Charset As String

The charset, such as "ISO-8859-1" or "utf-8"

ContentType As String

The MIME content type, such as "text/plain", "text/html", "multipart/alternative", "multipart/mixed", etc.

Disposition As String

The content disposition, which can be "attachment", "inline", etc.

Encoding As String

A content encoding such as "base64", "quoted-printable", "7bit", "8bit", etc.

Filename As String

The filename when the content disposition is "attachment".

LastErrorHtml As String (read-only)

Error information in HTML format for the last method called.

LastErrorText As String (read-only)

Error information in plain-text format for the last method called.

LastErrorXml As String (read-only)

Error information in XML format for the last method called.

Micalg As String

The MIC algorithm, such as "SHA1" when the content type is multipart/signed. Properties such as this are rarely set manually, as Chilkat MIME automatically sets it to the correct value when creating a signed message.

Name As String

The name attribute of the content-type header field.

NumEncryptCerts As Long (read-only)

The number of certificates use for encryption. This property is set after UnwrapSecurity is called.

NumHeaderFields As Long (read-only)

The number of header fields. Header field names and values can be retrieved by index (starting at 0) by calling GetHeaderFieldName and GetHeaderFieldValue.

NumParts As Long (read-only)

The number of sub-parts contained within this message. Each sub-part is a complete Chilkat MIME message itself.

NumSignerCerts As Long (read-only)

The number of certificates use for signing. This property is set after UnwrapSecurity is called.

Protocol As String

A protocol such as "application/x-pkcs7-signature". Properties such as this are rarely set manually, as Chilkat MIME automatically sets it to the correct value when creating a signed message.

UnwrapExtras As Long

Controls whether extra (informative) header fields are added to the MIME message when unwrapping security.

UseMmDescription As Long

Controls whether the boilerplate text "This is a multi-part message in MIME format." is used as the body content of a multipart MIME part.

Version As String (read-only)

The version, such as "1.0.0".

Methods

AddDetachedSignature(cert As ChilkatCert) As Long

Signs the message using the certificate provided. If successful, the message is converted to "multipart/signed" and the original message will be contained in the first sub-part.

AddDetachedSignature2(cert As ChilkatCert, transferHeaderFields As Long) As Long

Same as AddDetachedSignature, except an extra argument is provided to control whether header fields from the calling MIME object are transferred to the content part of the multipart/signed object. This method transforms the calling object into a multipart/signed MIME with two sub-parts. The first contains the original content of the calling object, and the second contains the digital signature.

Returns 1 for success, 0 for failure.

AddDetachedSignaturePk(cert As ChilkatCert, key As PrivateKey) As Long

To be documented soon.

AddDetachedSignaturePk2(cert As ChilkatCert, key As PrivateKey, transferHeaderFields As Long) As Long

To be documented soon...

AddHeaderField(fieldName As String, fieldValue As String)

Adds a header field to the MIME.

AppendPart(iMime As ChilkatMime)

Appends a MIME message to the sub-parts of this message. Arbitrarily complex messages with unlimited nesting levels can be created. If the calling Mime object is not already multipart, it is automatically converted to multipart/mixed first.

AppendPartFromFile(fileName As String) As Long

Loads a file and creates a Mime message object using the file extension to determine the content type, and adds it as a sub-part to the calling object.

ContainsEncryptedParts() As Long

Returns 1 if the MIME message contains encrypted parts.

ContainsSignedParts() As Long

Returns 1 if the MIME message contains signed parts.

Convert8Bit()

(PreRelease) Changes the content-transfer-encoding to "base64" for all 8bit or binary MIME subparts. This allows for the MIME to be exported as a string via the GetMime method.

ConvertToMultipartAlt() As Long

To be documented soon.

ConvertToMultipartMixed() As Long

To be documented soon.

ConvertToSigned(cert As ChilkatCert) As Long

Digitally signs the calling Mime object, but rather than the signature becoming a sub-part of the message (as in AddDetachedSignature) it becomes part of the message. In S/MIME terms, the message becomes application/x-pkcs7-mime rather than multipart/signed.

ConvertToSignedPk(cert As ChilkatCert, key As PrivateKey) As Long

To be documented soon...

Decrypt() As Long

To be documented soon.

Decrypt2(cert As ChilkatCert, key As PrivateKey) As Long

To be documented soon.

Encrypt(cert As ChilkatCert) As Long

Encrypt a MIME message object using a digital certificate.

GetBodyBinary() As Variant

Returns the body of the MIME message as a block of binary data. The body is automatically converted from its encoding type, such as base64 or quoted-printable, before being returned.

GetBodyDecoded() As String

Returns the body of the MIME message as a string. The body is automatically converted from its encoding type, such as base64 or quoted-printable, before being returned.

GetBodyEncoded() As String

Returns the body of the MIME message as a String. The body is explicitly not decoded from it's encoding type, so if it was represented in Base64, you will get the Base64 encoded body, as an example.

Returns a null on failure

GetEncryptCert(index As Long) As ChilkatCert

Returns the Nth certificate used for encryption. Most likely the message was only encrypted once, and if so, the index should be set to 0.

Returns a null on failure

GetEntireHead() As String

Returns the MIME header.

Returns a null on failure

GetHeaderField(name As String) As String

Returns a null on failure

GetHeaderFieldName(index As Long) As String

Returns the Nth MIME header field name.

Returns a null on failure

GetHeaderFieldValue(index As Long) As String

Returns the Nth MIME header field value.

Returns a null on failure

GetMime() As String

Returns a string containing the complete MIME message, including all sub-parts.

Returns a null on failure

GetMimeBytes() As Variant

(PreRelease) Returns a byte array containing the complete MIME message, including all sub-parts.
