Delphi ActiveX

Create MIME Containing XML

See more MIME Examples

Calls SetBodyFromXml to load XML into the MIME body. Also sets the Content-Type header to "text/xml", and the Content-Transfer-Encoding to an appropriate transfer encoding based on the characters found in the XML. 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
success: Integer;
mime: TChilkatMime;
xmlData: WideString;

begin
success := 0;

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

mime := TChilkatMime.Create(Self);

// Add a few header fields:
success := mime.AddHeaderField('Description','this is a test');
success := mime.AddHeaderField('MyId','123');

xmlData := '<something>123</something>';

// Set the mime body via SetBodyFromXml.  This also
// has the intended side-effect of adding the Content-Type
// and Content-Transfer-Encoding headers.
success := mime.SetBodyFromXml(xmlData);

Memo1.Lines.Add(mime.GetMime());

// The MIME should look like this:

// Description: this is a test
// MyId: 123
// Content-Type: text/xml; 
// Content-Transfer-Encoding: 7bit
// 
// <something>123</something>

// Note: The Content-Transfer-Encoding may be changed.
// For example, to use "base64", do this:
mime.Encoding := 'base64';

// Show the MIME again, this time using the base64 
// transfer encoding:
Memo1.Lines.Add(mime.GetMime());

// It should look like this:

// Description: this is a test
// MyId: 123
// Content-Type: text/xml; 
// Content-Transfer-Encoding: base64
