Compose a new mail message.
Syntax
object.ComposeMessage( From, To,
[Cc], [Bcc], [Subject], [MessageText],
[MessageHTML], [CharacterSet], [EncodingType] )
Parameters
- From
- A string that specifies the sender's email address. Only a
single address should be used. After the message has been composed,
the From
property will be updated with this value.
- To
- A string that specifies one or more recipient email addresses.
Multiple email addresses may be specified by separating them with
commas. After the message has been composed, the To
property will be updated with this value.
- Cc
- An optional string that specifies one or more additional
recipient addresses that will receive a copy of the message. If this
argument is not specified, then no Cc header field will be created
for this message. After the message has been composed, the Cc property
will be updated with this value.
- Bcc
- An optional string that specifies one or more additional
recipient addresses that will receive a copy of the message. Unlike
the cc argument, these recipients will not be
included in the header of the message. If this argument is not
specified, then no blind carbon copies of the message will be sent.
After the message has been composed, the Bcc property will be
updated with this value.
- Subject
- An optional string that specifies the subject for the message.
If the argument is not specified, then no Subject header field will
be created for this message. After the message has been composed,
the Subject property will be updated with this value.
- MessageText
- An optional string that contains the body of the message. Each
line of text contained in the string should be terminated with a
carriage-return/linefeed (CRLF) pair, which is recognized as the
end-of-line. If this parameter is not specified, then the message
will have an empty body unless the MessageHTML parameter has
been specified.
- MessageHTML
- An optional string that contains an alternate HTML formatted
message. If the MessageText parameter has been
specified, then a multipart message will be created with both plain
text and HTML text as the alternative. This allows mail clients to
select which message body they wish to display. If the MessageText
parameter is not specified or is an empty string, then the message
will only contain HTML. Although this is supported, it is not
recommended because older mail clients may be unable to display the
message correctly.
- CharacterSet
- An optional integer value which specifies the
character set for the message text.
If this parameter is omitted, the default is for the message to be
composed using the standard UTF-8 character set.
- EncodingType
- An optional integer value which specifies the default encoding
for the message. If this parameter is omitted, the message will use
standard 8-bit encoding. This parameter may be one of the following
values:
| Value |
Description |
| mailEncoding7Bit |
Each character is encoded in one or more bytes, with each
byte being 8 bits long, with the first bit cleared. This encoding
is most commonly used with plain text using the US-ASCII
character set, where each character is represented by a single
byte in the range of 20h to 7Eh. |
| mailEncoding8Bit |
Each character is encoded in one or more bytes, with each
byte being 8 bits long and all bits are used. 8-bit encoding is
used with UTF-8 and other multi-byte character sets. |
| mailEncodingBinary |
Binary encoding is essentially the absence of any encoding
performed on the message data, and there is no presumption that
the data contains textual information. No character set
localization or conversion is performed on binary encoded data.
This encoding type is not recommended. Instead, binary data
should be encoded using the standard base64 algorithm. |
| mailEncodingQuoted |
Quoted-printable encoding is designed for textual messages
where most of the characters are represented by the ASCII
character set and is generally human-readable. Non-printable
characters or 8-bit characters with the high bit set are encoded
as hexadecimal values and represented as 7-bit text.
Quoted-printable encoding is typically used for messages which
use character sets such as ISO-8859-1, as well as those which use
HTML. |
| mailEncodingBase64 |
Base64 encoding is designed to represent binary data in a
form that is not human readable but which can be safely exchanged
with servers that only accept 7-bit data. Base64 encoding is
typically used with file attachments. |
| mailEncodingUucode |
Uuencoding and uudecoding is a legacy encoding format that
was used before the MIME standard was established. This encoding
method has largely been replaced by base64 encoding, although it
is still commonly used for binary newsgroup postings on USENET.
Although this encoding format is supported, it is not officially
part of the MIME standard and its use in email messages is
discouraged. |
Return Value
A value of zero is returned if the method succeeds.
Otherwise, a non-zero error code is returned which indicates the
cause of the failure.
Remarks
The ComposeMessage method will
replace the current message if one already exists.
Example
The following example composes a message and sends it to the
specified recipients:
Dim nError As Long
nError = InternetMail1.ComposeMessage(comboFrom.Text, _
editTo.Text, _
editCc.Text, _
editBcc.Text, _
editSubject.Text, _
editMessage.Text)
If nError > 0 Then
MessageBox "Unable to compose message", vbExclamation
Exit Sub
End If
nError = InternetMail1.SendMessage()
If nError > 0 Then
MsgBox "Unable to send message", vbExclamation
Exit Sub
End If
