程序中主要使用了InitiateSystemShutdown()这个函数。
|
CString CPage1::ShowError()
{
LPVOID lpMsgBuf;
::FormatMessage(
FORMAT_MESSAGE_ALLOCATE_BUFFER |
FORMAT_MESSAGE_FROM_SYSTEM |
FORMAT_MESSAGE_IGNORE_INSERTS,
NULL,
::GetLastError(),
MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), // Default language
(LPTSTR) &lpMsgBuf,
0,
NULL
);
CString strMsg((LPCTSTR)lpMsgBuf);
::LocalFree( lpMsgBuf );
return strMsg;
} |
关机：
|
void CPage1::OnShutdown()
{
GetDlgItem(IDC_STATE)->SetWindowText("正在试图关闭计算机，请稍候...");
static HANDLE hToken;
static TOKEN_PRIVILEGES tp;
static LUID luid;
if(::OpenProcessToken(GetCurrentProcess(),
TOKEN_ADJUST_PRIVILEGES|TOKEN_QUERY,
&hToken))
{
::LookupPrivilegeValue(NULL,SE_SHUTDOWN_NAME,&luid);
tp.PrivilegeCount=1;
tp.Privileges[0].Luid =luid;
tp.Privileges[0].Attributes =SE_PRIVILEGE_ENABLED;
::AdjustTokenPrivileges(hToken,false,&tp,sizeof(TOKEN_PRIVILEGES),NULL,NULL);
}
UpdateData(true);
CString str;
str.Format("\\\\%s",m_strName);
if(!::InitiateSystemShutdown(
(LPTSTR)(LPCTSTR)str,
"\n不好意思，我要关机了!",
m_nTime,
m_bAlert==0?true:false,
m_nType==0?false:true
))
{
GetDlgItem(IDC_STATE)->SetWindowText(this->ShowError());
}
else
GetDlgItem(IDC_STATE)->SetWindowText("关机成功");
} |
取消关机：
|
void CPage1::OnAbort()
{
GetDlgItem(IDC_STATE)->SetWindowText("正在试图取消关机操作，请稍候...");
UpdateData(true);
CString str;
str.Format("\\\\%s",m_strName);
if(!::AbortSystemShutdown((LPTSTR)(LPCTSTR)str))
{
GetDlgItem(IDC_STATE)->SetWindowText(this->ShowError());
}
else
GetDlgItem(IDC_STATE)->SetWindowText("取消成功");
} |
休眠：
void CPage1::OnXiu()
{
if(MessageBox("确实要休眠吗?","关机程序",MB_YESNO|MB_DEFBUTTON2|MB_ICONQUESTION)==IDYES)
{
static HANDLE hToken;
static TOKEN_PRIVILEGES tp;
static LUID luid;
if(::OpenProcessToken(GetCurrentProcess(),
TOKEN_ADJUST_PRIVILEGES|TOKEN_QUERY,
&hToken))
{
::LookupPrivilegeValue(NULL,SE_SHUTDOWN_NAME,&luid);
tp.PrivilegeCount=1;
tp.Privileges[0].Luid =luid;
tp.Privileges[0].Attributes =SE_PRIVILEGE_ENABLED;
::AdjustTokenPrivileges(hToken,false,&tp,sizeof(TOKEN_PRIVILEGES),NULL,NULL);
}
::SetSystemPowerState(false,true);
}
