Description
The SMTP_Attachment command provides a means to attach text or binary files to your message in MIME format. This command may be called multiple times in order to attach multiple documents to one mail message. If a value greater than zero is passed to the encodeType parameter, this command will perform encoding at the time the message is sent.
smtp_ID is the long integer reference to the mail message created with the SMTP_New command.
fileName contains the name of the file you want to attach to the message. This value may be specified three different ways:
| "" | = Display the Standard Open File dialog. |
| "FileName" | = Looks for FileName in the same directory as the structure of the database. |
| "Path:FileName" | = Complete path of the file including FileName. |
encodeType is an Integer value indicating what type of encoding will be done on the file before it is incorporated into the message. If attaching a binary file, an encoding method must be applied capable of the proper conversion (BinHex, AppleSingle). The most common encoding method is BinHex.
If you pass positive values of encodeType the command will automatically encode the file using the specified method when the message is sent. The encoding of a file occurs at the time the SMTP_Send command is issued. If the file is large it may take some time for the SMTP_Send command to complete. Significant time may be saved in cases where the same file will be sent a number of times. In these cases it is best to encode the file one time with the IT_Encode command and then attach the resulting file to your message using the negative value of encodeType. A negative value in encodeType will not perform any additional encoding but will set the message headers to the correct encoding method of the attached file. This will inform your recipients' mail reader of the correct way to interpret your attachment.
Note: You cannot pass an array element to the encodeType parameter.
deleteOption is an optional integer parameter which specifies how to treat the attachment. A value of zero will add the attachment to the current list of attachments. A value of 1 will replace all attachments with the file in fileName. If fileName is a null string, all attachments will be removed. A value of 2 will remove only the attachment listed in fileName from the list of attachments.
