创建独立的流程! [英] Creating independent process!
问题描述
我正在尝试使用C ++中的服务创建一个进程.这个新过程正在创建为子过程.我想创建一个独立的进程而不是一个子进程...
I am trying to create a process from a service in C++. This new process is creating as a child process. I want to create an independent process and not a child process...
我正在使用CreateProcess函数.由于我创建的新进程是子进程,因此当我尝试在服务级别终止进程树时,它也正在终止子进程……我不希望这种情况发生.我希望创建的新进程独立于服务运行.
I am using CreateProcess function for the same. Since the new process i create is a child process when i try to kill process tree at the service level it is killing the child process too... I dont want this to happen. I want the new process created to run independent of the service.
请在同一点上提出建议.谢谢.
Please advice on the same.. Thanks..
代码
STARTUPINFO si;
PROCESS_INFORMATION pi;
ZeroMemory( &si, sizeof(si) );
si.cb = sizeof(si); // Start the child process.
ZeroMemory( &pi, sizeof(pi) );
si.dwFlags = STARTF_USESHOWWINDOW;
if(bRunOnWinLogonDesktop)
{
if(csDesktopName.empty())
si.lpDesktop = _T("winsta0\\default");
else
_tcscpy(si.lpDesktop, csDesktopName.c_str());
}
if(bHide)
si.wShowWindow = SW_HIDE; /* maybe even SW_HIDE */
else
si.wShowWindow = SW_SHOW; /* maybe even SW_HIDE */
TCHAR szCmdLine[512];
_tcscpy(szCmdLine, csCmdLine.c_str());
if( !CreateProcess( NULL,
szCmdLine,
NULL,
NULL,
FALSE,
CREATE_NEW_PROCESS_GROUP,
NULL,
NULL,
&si,
&pi ) )
推荐答案
在关闭子进程的线程和进程处理程序之后,它仍然是Process Explorer中的一个子进程,但是结束父进程不会导致终止该子进程
After closing thread and process handlers of the child process, it's still a child in the Process Explorer, but ending parent process doesn't cause termination of the child one.
CreateProcess( NULL,
szCmdLine,
NULL,
NULL,
FALSE,
CREATE_NEW_PROCESS_GROUP,
NULL,
NULL,
&si,
&pi );
if(pi.hThread)
CloseHandle(pi.hTread);
if(pi.hProcess)
CloseHandle(pi.hProcess);
我在 ReactOS 的="nofollow"> cmd.exe的来源.执行启动"命令的过程.
I've found this decision in sources of cmd.exe of the ReactOS, in the procedure of executing 'start' command.
