代码说话，各函数功能一目了然：

  
    1 
   void
    shelltest()

    2 
   {
  
  
   
    3 
       wxExecute(wxT(
   "
   notepad.exe newfile.txt
   "
   ));

    4 
   }

    5 
   

    6 
    
   void
    sysutils()

    7 
   {

    8 
       wxString output(wxT(
   "
   Home dir:
   "
   ));

    9 
       output
   <<
   wxGetHomeDir();

   10 
       output
   <<
   wxT(
   "
   \nOs Description:
   "
   )
   <<
   wxGetOsDescription();

   11 
       output
   <<
   wxT(
   "
   \nUse Name:
   "
   )
   <<
   wxGetUserName();

   12 
       output
   <<
   wxT(
   "
   \nUser Id:
   "
   )
   <<
   wxGetUserId();

   13 
       output
   <<
   wxT(
   "
   \nEmail Address:
   "
   )
   <<
   wxGetEmailAddress();

   14 
       output
   <<
   wxT(
   "
   \nFull Host Name:
   "
   )
   <<
   wxGetFullHostName();

   15 
       output
   <<
   wxString::Format(wxT(
   "
   \nFree Memory:%.2fG
   "
   ),(
   double
   )wxGetFreeMemory().ToLong()
   /
   1024
   /
   1024
   /
   1024
   );

   16 
       output
   <<
   wxString::Format(wxT(
   "
   \n64bit?%s
   "
   ),wxIsPlatform64Bit()
   ?
   wxT(
   "
   Yes
   "
   ):wxT(
   "
   No
   "
   ));

   17 
       output
   <<
   wxString::Format(wxT(
   "
   \nLittle Endian?%s
   "
   ),wxIsPlatformLittleEndian()
   ?
   wxT(
   "
   Yes
   "
   ):wxT(
   "
   No
   "
   ));

   18 
       cout
   <<
   output
   <<
   endl;
