Add Content-Length Header to a MIME Message

See more MIME Examples

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

uses
    Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
    Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls, Chilkat_TLB;

...

procedure TForm1.Button1Click(Sender: TObject);
var
mime: TChilkatMime;

begin
// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

mime := TChilkatMime.Create(Self);

// Set the MIME body:
mime.SetBody('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.
mime.AddContentLength();

// Display the MIME:
Memo1.Lines.Add(mime.GetMime());
end;
