注意事项：

1.ParamStr(0)是实例自己。

2.传的参数是以空格分看的。

3.“‘2 Hello World”，ParamStr(1) = '2' ；

PS:如果使用CreateProcess建进程，怎么发参数呢？

 1     if not IsBuildInFit then
 2     begin //不代参数
 3       bActiveState := CreateProcess(PChar(nil), PChar(GetExePath + sHardWareName), @lpsaProcess,
 4               @lpsaThread, false, CREATE_SHARED_WOW_VDM, PChar(nil), PChar(nil),
 5               lpsiStartInfo, oProcInfo);
 6     end
 7     else
 8     begin //代参数
 9       bActiveState := CreateProcess(PChar(nil), PChar(GetExePath + sHardWareName + ' True'), @lpsaProcess,
10               @lpsaThread, false, CREATE_SHARED_WOW_VDM, PChar(nil), PChar(nil),
11               lpsiStartInfo, oProcInfo);
12     end;
