这个例子是讲 how to 调用桌面应用程序，比如：WPS电子表格

{$mode objfpc}{$H+}

uses
  SysUtils,Variants,ComObj,ActiveX,Windows;
  
const
  Com = 'KET.Application';
var
  App :Variant;
  wbook :Variant;
  Filename :WideString;
  
begin
  if Assigned(InitProc) then
	TProcedure(InitProc);
  try
    App:= CreateOleObject(Com);
    App.Visible:= True;
    Filename:= App.GetOpenFilename('Excel Files (*.xls), *.xls');
	if FileExists(Filename) then
	  wbook:= App.Workbooks.Open(Filename);
  except
    writeln(' Open Error ');
  end;
