Create Binary MIME

Demonstrates how to create a MIME document using the "binary" content-transfer-encoding.

CREATE PROCEDURE ChilkatSample
AS
BEGIN
    DECLARE @hr int
    DECLARE @sTmp0 nvarchar(4000)
    DECLARE @mime int
    EXEC @hr = sp_OACreate 'Chilkat.Mime', @mime OUT

    --  Set a custom headerr field:
    EXEC sp_OAMethod @mime, 'AddHeaderField', NULL, 'Content-ID', 'PDFFile'

    --  Load a PDF file into the MIME body-part of the message.
    --  Note: This automatically sets the content-type and
    --  content-transfer-encoding header fields to appropriate values
    --  based on the file extension.  If specific values for these
    --  header fields are required, set the ContentType and
    --  Encoding properties after (as shown here)
    EXEC sp_OAMethod @mime, 'SetBodyFromFile', @success OUT, 'test.pdf'
    IF @success = 0

    --  Use binary MIME -- the MIME body will not be encoded
    --  but will instead consist of the binary data of the file.
    EXEC sp_OASetProperty @mime, 'Encoding', 'binary'

    --  Make sure our content-type is "application/pdf"
    --  (It should already be this value...)
