wxWidgets 几个实用的系统函数

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;
19 }
