(SQL Server) Add Content-Length Header to a MIME Message

The AddContentLength method automatically computes the length of the MIME content and adds a Content-Length header with the correct number of bytes.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows

CREATE PROCEDURE ChilkatSample

    DECLARE @sTmp0 nvarchar(4000)
    -- This example assumes the Chilkat API to have been previously unlocked.
    -- See Global Unlock Sample for sample code.

    DECLARE @mime int
    -- Use "Chilkat_9_5_0.Mime" for versions of Chilkat < 10.0.0

    EXEC sp_OAMethod @mime, 'SetBody', NULL, 'This is a test'

    -- The complete size (in bytes) of the contents is computed, 
    -- even if the MIME is multipart, and the Content-Length header
    -- is added.
