重启计算机、唤醒计算机、使计算机休眠_python如何使用代码将休眠模式的电脑唤醒windows10

 IPHelper函数GetAdaptersInfo，然后自己计算

按一定格式分解字符串的函数是哪个？如分解"aaa,bbb,ccc",
AfxExtractSubString

重启计算机
void RestartPC()
{

  char szInfo[1024];
  memset(szInfo,0,sizeof(szInfo));
  sprintf(szInfo,"重新启动！");
  OutputDebugString(szInfo);

  HANDLE hToken;
  TOKEN_PRIVILEGES tkp;
  BOOL fResult;

  //打开与当前进程相关联的存取标识
  if (!::OpenProcessToken(GetCurrentProcess(),TOKEN_ADJUST_PRIVILEGES
   |TOKEN_QUERY,&hToken))
   OutputDebugString("OpenProcessToken failed");
  //查出本机系统的当前特权的Luid
  ::LookupPrivilegeValue(NULL,SE_SHUTDOWN_NAME,&tkp.Privileges[0].Luid);
  tkp.PrivilegeCount =1;
  tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
  ::AdjustTokenPrivileges(hToken,FALSE,&tkp,0,(PTOKEN_PRIVILEGES)     NULL,0);
  if (::GetLastError()!=ERROR_SUCCESS)
   OutputDebugString("AdjustTokenPrivileges enable failed");
  fResult = ::InitiateSystemShutdown(NULL,"即将关机",8,TRUE,TRUE);
  if (!fResult)
   OutputDebugString("InitiateSystemShutDown failed");
  tkp.Privileges[0].Attributes = 0;
  ::AdjustTokenPrivileges(hToken,FALSE,&tkp,0,(PTOKEN_PRIVILEGES)   NULL,0);
  if (::GetLastError()!=ERROR_SUCCESS)
   OutputDebugString("AdjustTokenPrivileges disable failed");

}

拷贝文件夹
SHFILEOPSTRUCT    fo;
    char szFrom[500]={0},szTo[500]={0};
    fo.hwnd=m_hWnd;
    ::lstrcpy(szFrom,"c://abc//*.*");
    ::lstrcpy(szTo,"d://jqk");
    fo.pFrom=szFrom;
    fo.pTo=szTo;
    fo.wFunc=FO_COPY;
    fo.fAnyOperationsAborted=TRUE;
    fo.fFlags=FOF_NOCONFIRMMKDIR | FOF_NOCONFIRMATION;
    fo.hNameMappings=NULL;
    fo.lpszProgressTitle=NULL;
    ::SHFileOperation(&fo);

 

同时按下了CTRL+F键
msg.message==WM_KEYDOWN && msg.wParam='F' && ( 0x8000&GetKeyState(VK_CONTROL))

有一段字符串(CString)前后都有汉字中间是英文，如何将英文提取出来？
IsDBCSLeadByte(str.GetAt(i));这样的形式

判断文件是否存在
1.PathFileExists   ||  PathIsDirectory
2.GetFileAttributes
3.
include <io.h>
if(_access(filename,0)!=-1)
{
  printf("file exit");
}

唤醒计算机
BOOL RequestWakeupLatency(
  LATENCY_TIME latency      // latency requirement
);

使计算机休眠
#define RTN_ERROR 13

  void PERR(LPTSTR szAPI, DWORD dwLastError) //休眠时调用到的一个函数,用来
  记录休眠中遇到的错误

  {
  LPTSTR MessageBuffer;
  DWORD dwBufferLength;
  fprintf(stderr,"%s error! (rc=%lu)/n", szAPI, dwLastError);

  if(dwBufferLength=FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER |
  FORMAT_MESSAGE_FROM_SYSTEM,
  NULL,
  dwLastError,
  LANG_NEUTRAL,
  (LPTSTR) &MessageBuffer,
  0,
  NULL))
  {

  DWORD dwBytesWritten;

  WriteFile(GetStdHandle(STD_ERROR_HANDLE),
  MessageBuffer,
  dwBufferLength,
  &dwBytesWritten,
  NULL);
  LocalFree(MessageBuffer);
  }
  }

  int SetPower() //主要功能函数
  {

  TOKEN_PRIVILEGES tp;
  HANDLE hToken;
  LUID luid;

  LPTSTR MachineName=NULL;

  if(!OpenProcessToken(GetCurrentProcess(), 从这里
  TOKEN_ADJUST_PRIVILEGES,
  &hToken ))
  {
  PERR("OpenProcessToken", GetLastError() );
  return RTN_ERROR;
  }

  if(!LookupPrivilegeValue(MachineName, SE_SHUTDOWN_NAME, &luid))

  {
  PERR("LookupPrivilegeValue", GetLastError() );
  return RTN_ERROR;
  }

  tp.PrivilegeCount = 1;
  tp.Privileges[0].Luid = luid;
  tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;

  AdjustTokenPrivileges(hToken, FALSE, &tp, sizeof(TOKEN_PRIVILEGES),
  NULL, NULL ); 到这里,是取得权限//

  SetSystemPowerState(FALSE,TRUE);
  return 0;

  }

void CDrawfromDlg::OnButton1()
{
        SetPower();
   
}
