unit Unit1;

// include EASendMailObjLib_TLB unit to your Delphi Project
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, EASendMailObjLib_TLB, StdCtrls;

You can also create “EASendMailObjLib_TLB.pas” manually like this:

    Form1: TForm1;


{$R *.dfm}

Procedure TForm1.Button1Click(Sender: TObject);
