若已知进程HANDLE,怎么判断进程是否已经结束?

[tonybaobao]

我用ShellExecuteEx获得了HANDEL,但是我用什么API可以得知该进程已经执行完毕?因为我要在该进程完毕后才能进行一些处理.谢谢.

WaitForSingleObject

[tonybaobao]

我也知道有这么一个API,但是不知道怎么用.我用过了,可是似乎没法判断.谁能给个例子看看.

WaitForSingleObject
or
GetExitCodeProcess

[msdn_user]

GetExitCodeProcess
The GetExitCodeProcess function retrieves the termination status of the specified process.

BOOL GetExitCodeProcess(
HANDLE hProcess, // handle to the process
LPDWORD lpExitCode // termination status
);
Parameters
hProcess
[in] Handle to the process.
Windows NT/2000 or later: The handle must have PROCESS_QUERY_INFORMATION access. For more information, see Process Security and Access Rights.

lpExitCode
[out] Pointer to a variable to receive the process termination status.
Return Values
If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks
If the specified process has not terminated, the termination status returned is STILL_ACTIVE. If the process has terminated, the termination status returned may be one of the following:

The exit value specified in the ExitProcess or TerminateProcess function.
The return value from the main or WinMain function of the process.
The exception value for an unhandled exception that caused the process to terminate.

好象用WaitForSingleObject()来等待线程句柄的返回吧

谢谢各位,我等会儿试试看.

[jozu]

WaitForSingleObject(hYourProcess, INIFINATE);
返回的时候hYourProcess就是结束状态

嘿嘿，这叫什么意思？我的回答不准确么？居然没有分？搞不懂怎么回事
