如何让一个应用程序不出现在任务栏上？

Question

一般Windows运行程在任务栏上，
  要实现该功能要在OnCreate事件里利用到API函序时都会在任务栏上出现按钮，我想不让它出现数SetWindowLongprocedure TForm1.Button1Click(Sender: TObject);
begin
  SetWindowLong(Application , Handle , GWL_EXSTYLE, WS_EX_TOOLWINDOW);
end;　但是上面这段代码却提示两个错误：
[Error] Unit1.pas(28): Incompatible types: 'HWND' and 'TApplication'　
[Error] Unit1.pas(28): Too many actual parameters在线等，谢谢!
