Let's consider a simple Delphi form (Form2) which contains button "Button1".

<blockquote>

<pre>
<font color="blue"><b>unit</b></font> TestDfm2;

<font color="blue"><b>interface</b></font>

<font color="blue"><b>uses</b></font>
  Windows, Messages, SysUtils, Classes, Graphics,   Controls, Forms, Dialogs,
  StdCtrls;

<font color="blue"><b>type</b></font>
  TForm2 = <font color="blue"><b>class</b></font>(TForm)
    Button1: TButton;
    <font color="blue"><b>procedure</b></font> Button1Click(Sender: TObject);
  <font color="blue"><b>private</b></font>
    { <font color="blue"><b>Private</b></font> declarations }
  <font color="blue"><b>public</b></font>
    { <font color="blue"><b>Public</b></font> declarations }
  <font color="blue"><b>end</b></font>;

<font color="blue"><b>var</b></font>
  Form2: TForm2;

<font color="blue"><b>implementation</b></font>

{$R *.DFM}

<font color="blue"><b>procedure</b></font> TForm2.Button1Click(Sender: TObject);
<font color="blue"><b>begin</b></font>
  ShowMessage(<font color="Red">'Hello from Delphi!'</font>);
<font color="blue"><b>end</b></font>;

<font color="blue"><b>end</b></font>.
</pre>
</blockquote>


<p>
Open new project, then drop TPaxScripter, TPaxPascal, TPaxDfmConverter, 2 TButton 
and TMemo components on the main form and inlcude Form2 in your project.

<p>
Button1 will generate script by dfm-file which represents Form2. 
Memo1 will show the generated script. Button2 will show Form2 "as is":
