I don't know the class. With directly using the ShellExecute API instead :

declare long ShellExecute in "shell32.dll" ;
	long hwnd, string lpszOp, ;
	string lpszFile, string lpszParams, ;
    string lpszDir, long nShowCmd

lcFileToOpen = '"C:\My Folder\MyFile.txt"'
ShellExecute(0,'Open',;
  '"C:\Program Files\Windows NT\Accessories\wordpad.exe"',;
  m.lcFileToOpen,'',1)
