MIME Control

Properties   Methods   Events   Configuration Settings   Errors  

The MIME control allows for the simple encoding and decoding of MIME structures such as message attachments, file uploads, etc.

Syntax

MIME

Remarks

The control may be used for decoding or encoding of messages. Message holds the content of the encoded message or the filename which holds the encoded data. The decoded data is provided in Parts properties.

To decode a MIME message you should first assign either the whole message (headers and body) to Message or put the message headers into the MessageHeaders property and the message body or the filename holding it into the Message property. Calling DecodeFromFile or DecodeFromString directs the control to start parsing the message: it will fill out the ContentType, ContentTypeAttr properties with message content type information, and enter information about message parts into the Parts properties, which includes: part sizes, part content types, part content type attributes, part content disposition, part content disposition attributes, part encoding, part name, part filename, part headers, or part content (part decoded string or part decoded file) for each decoded part.

Calling the DecodeFromString or DecodeFromFile to decode doesn't actually decode the message but only parses it. The real decoding is done when the part content in the Parts properties is first accessed.

To encode data into a MIME message you should first assign values for each part to either part decoded string or part decoded file in the Parts properties property, and optionally assign values to the other part attributes in the Parts properties. Assigning a value to the part decoded string or part decoded file through the Parts properties, fills out automatically the part headers into the Parts properties for the respective part. Calling EncodeToFile or EncodeToString directs the control to fill out the Message with the message body and the MessageHeaders with the headers.

The Progress event is fired as the message is parsed and the data is decoded/encoded.

This property is not available at design time.

Data Type

String

PartSize Property (MIME Control)

This property contains the size of the DecodedFile or DecodedString .

Syntax

mimecontrol.PartSize(PartIdx)

Default Value

0

Remarks

This property contains the size of the PartDecodedFile or PartDecodedString. If a non empty value is assigned to PartDecodedFile, then control fills out the corresponding PartSize with the file size or an error occurs if the file doesn't exist.

If the PartDecodedFile is empty and a value is assigned to PartDecodedString, then the corresponding PartSize will be equal to the string's size.

During decoding, this property is filled with the size of that part.

The PartIdx parameter specifies the index of the item in the array. The size of the array is controlled by the PartCount property.

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

Data Type

Integer

Config Method (MIME Control)

Sets or retrieves a configuration setting.

Syntax

mimecontrol.Config ConfigurationString

Remarks

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

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

DecodeFromFile Method (MIME Control)

Decodes from file.

Syntax

mimecontrol.DecodeFromFile 

Remarks

This method decodes the data file given in Message and optionally MessageHeaders and fills out the Parts properties for each decoded part.

Example (Decoding From File)

MIMEControl.Message = "C:\filename.txt" MIMEControl.DecodeFromFile

Here, C:\filename.txt must contain the MIME headers and body. If not, the MessageHeaders property must also be set to the appropriate MIME headers.

DecodeFromString Method (MIME Control)

Decodes from string.

Syntax

mimecontrol.DecodeFromString 

Remarks

This method decodes from string. Same as DecodeFromFile, but now the Message denotes the real encoded message rather than a filename.

This method decodes the data given in Message and optionally MessageHeaders and fills out the Parts properties.

Example (Decoding Mail Message)

MIMEControl.MessageHeadersString = MailControl.MessageHeaders MIMEControl.Message = MailControl.MessageText MIMEControl.DecodeFromString

DecodePart Method (MIME Control)

Decodes the specified part.

Syntax

mimecontrol.DecodePart index

Remarks

This method decodes the part specified by Index and returns the decoded part data.

DecodeFromString or DecodeFromFile must be called before calling this method. Calling this method will return the decoded bytes, and in addition the PartDecodedString property will be populated with the string representation of the decoded data.

For instance: mime.MessageHeadersString = myMessageHeaders; mime.Message = myMessageBody; mime.DecodeFromString(); byte[] myPartContent = await mime.DecodePart(0);

DecodePartToFile Method (MIME Control)

Decodes the specified part to a file on disk.

Syntax

mimecontrol.DecodePartToFile index

Remarks

This method decodes the part specified by Index to a temporary file. The full path to the temporary file is returned by this method. The user is responsible for deleting the temporary file.

DecodeFromString or DecodeFromFile must be called before calling this method.

EncodeToFile Method (MIME Control)

Encodes to file.

Syntax

mimecontrol.EncodeToFile 

Remarks

This method encodes the data given in Parts properties (either decoded file or decoded string) into a MIME message at Message and MessageHeaders using the values optionally given in Parts properties. To encode several objects into a MIME envelope, the user should first clear any old values left in the Parts properties.

The control will check for each item in Parts properties (first decoded file and then the decoded string) for the data to encode.

The encoded message will be saved in the file pointed to by Message; the message headers will be held by MessageHeaders.

Example (Encoding Data)

MIMEControl.ResetData() MIMEControl.PartCount = 2 MIMEControl.PartDecodedString(0) = "This is plain text data" MIMEControl.PartEncoding(0) = peQuotedPrintable MIMEControl.PartContentType(0) = "text/plain" MIMEControl.PartDecodedFile(1) = "C:\filename.txt" MIMEControl.Message = "temp.tmp" MIMEControl.EncodeToFile()

EncodeToString Method (MIME Control)

Encodes to string.

Syntax

mimecontrol.EncodeToString 

Remarks

This method encodes to string. Same as EncodeToFile but the encoded data is held in the Message property rather than saved to a file.

This method encodes the data given in Parts properties into a MIME message. The Message gets stored in Message and MessageHeaders using the values optionally given in Parts properties. To encode several objects into a MIME envelope, the user should first clear any old values left in the Parts properties by calling ResetData.

The control will check each item in Parts properties (first decoded file and then decoded string) for the data to encode.

The encoded message will be stored in the Message property; the message headers will be held by MessageHeaders.

Example (Encoding Data)

MIMEControl.ResetData() MIMEControl.PartCount = 2 MIMEControl.PartDecodedString(0) = "This is plain text data" MIMEControl.PartEncoding(0) = peQuotedPrintable MIMEControl.PartContentType(0) = "text/plain" MIMEControl.PartDecodedFile(1) = "C:\filename.txt" MIMEControl.EncodeToString()

Reset Method (MIME Control)

Reset the control.

Syntax

mimecontrol.Reset 

Remarks

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

ResetData Method (MIME Control)

Resets the values of all headers and Part- properties.

Syntax

mimecontrol.ResetData 

Remarks

This method resets the values of all headers and Part- properties. It is an easy way to reset the control's properties before starting to populate the Part- properties with new values.

Error Event (MIME Control)

Information about errors during data delivery.

Syntax

Sub mimecontrol_Error(ErrorCode As Integer, Description As String)

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the control fails with an error.

ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

Header Event (MIME Control)

Fired every time a header is parsed.

Syntax

Sub mimecontrol_Header(PartIndex As Integer, Field As String, Value As String)

Remarks

The PartIndex parameter contains the index of the part containing the current header. If the header is from the MIME body, this value will be -1. The Field parameter contains the name of the MIME header. The Value parameter contains the header contents. The Header event is fired when a header is parsed, which occurs for each header of the Message when DecodeFromFile, DecodeFromString, or DecodeFromStream is called.

Progress Event (MIME Control)

Shows the progress of decoding/encoding the input data.

Syntax

Sub mimecontrol_Progress(PercentDone As Integer)

Remarks

The Progress allows the user to visualize the progress of processing the input data.

The PercentDone parameter shows what percentage of the input has been read.

Configuration Settings (MIME Control)

The control accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the control, access to these internal properties is provided through the Config method.

MIME Configuration Settings

DecodeMessageHeaders:   Instructs the component to automatically decode message headers.

Message headers that have been Quoted-Printable or Base-64 encoded are automatically decoded when this configuration setting is True. The default value of this setting is False.

IncludeHeaders:   Tells the control whether to include the headers when encoding the message.

If true, the control will include the headers when EncodeToFile or EncodeToString are called. If false, only the message will be encoded.

The default value for IncludeHeaders is false.

RequireVersionHeader:   Specifies whether or not the control should require the version header.

If true, the control will require that the "MIME-Version" header be included in the MessageHeaders. If the header is not present during decoding, the component fails with an error. This config is false by default.

SanitizeFilename:   Whether invalid characters are replaced in MIME part filenames.

If True, the control will replace invalid characters with an underscore when decoding the MIME message. This applies to the filename held in the PartFilename property. When True the following characters are considered invalid:

  • \
  • /
  • "
  • :
  • ?
  • *
  • <
  • >
  • |
Any characters with ASCII values between 0-31 are also considered invalid. The default value is False.
TempFilePath:   If set, the temporary files created during MIME decoding and encoding will be put in the path specified.

The TempFilePath property sets the path at which the temporary files will be created.

Base Configuration Settings

CodePage:   The system code page used for Unicode to Multibyte translations.

The default code page is Unicode UTF-8 (65001).
