如何知道用CreateProcess创建的进程已执行结束？

[pinemail]

在程序中，我调用CreateProcess函数来创建一个进程，我如何知道这个进程什么时候执行完成呢？
Thx

谢谢大家！
虽然问题仍然没有解决。。。
开新帖继续问！
呵呵～～～

WaitForSingleObject( 你的进程句柄, INFINITE );

查看MSDN里关于WaitForSingleObject的帮助就知道，它可以用来等待一个进程的结束，WaitForSingleObject执行时，就会等在那里，但不占用CPU时间，一旦正等待的进程退出，WaitForSingleObject才返回，上面的INFINITE是无限等待下去的意思。

还有两个办法为：
while( GetProgressExitCode( hProgress ) == STILLACTIVE )
Sleep( 0 );

下面也是一个办法：
C/C++ Code Example: Retrieving Task Exit Code
This example retrieves the last exit code returned by a known task. (A returned value of "0" indicates the task was never run.) The example assumes that the task, Test Task, already exists on the local computer.

#include <windows.h>
#include <initguid.h>
#include <ole2.h>
#include <mstask.h>
#include <msterr.h>
#include <wchar.h>

int main(int argc, char **argv)
{
HRESULT hr = ERROR_SUCCESS;


///////////////////////////////////////////////////////////////////
// Call CoInitialize to initialize the COM library and then
// CoCreateInstance to get the Task Scheduler object.
///////////////////////////////////////////////////////////////////
ITaskScheduler *pITS;
hr = CoInitialize(NULL);
if (SUCCEEDED(hr))
{
hr = CoCreateInstance(CLSID_CTaskScheduler,
NULL,
CLSCTX_INPROC_SERVER,
IID_ITaskScheduler,
(void **) &pITS);
if (FAILED(hr))
{
CoUninitialize();
return 1;
}
}
else
{
return 1;
}


///////////////////////////////////////////////////////////////////
// Call ITaskScheduler::Activate to get the Task object.
///////////////////////////////////////////////////////////////////
ITask *pITask;
LPCWSTR lpcwszTaskName;
lpcwszTaskName = L"TestTask";
hr = pITS->Activate(lpcwszTaskName,
IID_ITask,
(IUnknown**) &pITask);

// Release ITaskScheduler interface.
pITS->Release();

if (FAILED(hr))
{
wprintf(L"Failed calling ITaskScheduler::Activate: ");
wprintf(L"error = 0x%x\n",hr);
CoUninitialize();
return 1;
}


///////////////////////////////////////////////////////////////////
// Call ITask::GetExitCode. Note that this method is
// inherited from IScheduledWorkItem.
///////////////////////////////////////////////////////////////////
DWORD pdwExitCode;

hr = pITask->GetExitCode(&pdwExitCode);

// Release ITask interface.
pITask->Release();

if (FAILED(hr))
{
wprintf(L"Failed calling ITask::GetExitCode: ");
wprintf(L"error = 0x%x\n",hr);
CoUninitialize();
return 1;
}


wprintf(L"The last exit code of Test Task is: %d\n", pdwExitCode);


CoUninitialize();
return 0;
}

用GetExitCodeThread这个东东,具体参加MSDN

[椒椒子]

The GetExitCodeProcess function retrieves the termination status of the specified process.
BOOL GetExitCodeProcess(
HANDLE hProcess, // handle to the process
LPDWORD lpExitCode // termination status
);

[kingzai]

UINT ProcessStatus(LPVOID pParam)
{
PROCESS_INFORMATION pi;
STARTUPINFO si;
si.cb=sizeof(si);
si.wShowWindow=SW_SHOW;
si.dwFlags=STARTF_USESHOWWINDOW;
BOOL fRet=CreateProcess(NULL,
"d:\\temp\\disk1\\setup.exe -r",
NULL,
NULL,
FALSE,
NORMAL_PRIORITY_CLASS|CREATE_NEW_CONSOLE,
NULL,
NULL,
&si,
&pi);
if(fRet)
{
m_hPro=pi.hProcess;//保存当前进程句柄，在强制结束进程时使用。
}
if(::WaitForSingleObject(m_hPro,INFINITE)==WAIT_OBJECT_0)
{
AfxMessageBox("the Process is go over");
}
CloseHandle(m_hPro);
return 0;
}
