#86: How can I register the file extention with own application and context menu, linked to this ext?

In the next example will be registered the file extention (.newext) - files of this type will open using MyApp.Exe application. Also will be registered the one default action and two additional items in context menu, assigned
with this file extention.

Example:

uses
  Windows, Registry;

procedure TForm1.Button1Click(Sender: TObject);
begin
  with TRegIniFile.Create('') do
    try
      RootKey := HKEY_CLASSES_ROOT;
      WriteString('.newext', '', 'NewExt');
      WriteString('NewExt', '', 'Your description of NewExt files');
      WriteString('NewExt\DefaultIcon', '', 'C:\MyApp.Exe,0');
      WriteString('NewExt\Shell', '', 'This_Is_Our_Default_Action');
      WriteString('NewExt\Shell\First_Action', '','This is our first action');
      WriteString('NewExt\Shell\First_Action\command', '', 'C:\MyApp.Exe /LotsOfParamaters %1');
      WriteString('NewExt\Shell\This_Is_Our_Default_Action', '', 'This is our default action');
      WriteString('NewExt\Shell\This_Is_Our_Default_Action\command', '', 'C:\MyApp.Exe %1');
      WriteString('NewExt\Shell\Second_Action', '', 'This is our second action');
      WriteString('NewExt\Shell\Second_Action\command', '', 'C:\MyApp.Exe /TonsOfParameters %1');
   finally
      Free;
   end;
end;
