最简单的办法，运行外部程序
UINT WinExec(
LPCSTR lpCmdLine, // address of command line
UINT uCmdShow // window style for new application
);
lpCmdLine
命令行；像dos命令一样，可以加参数
delphi 中用ParamStr(Index: Integer): string; 获得参数，参考例子
procedure TForm1.FormCreate(Sender: TObject);
var
i: Integer;
for i := 0 to ParamCount ?1 do
begin
if LowerCase(ParamStr(i)) = 'beep' then
Beep(10000,1000)
else if (LowerCase(ParamStr(i)) = 'exit' then
Application.Terminate;
end;
end;
uCmdShow 程序打开时的状态，
