How to use ::TerminateProcess to terminate a process?

[fantasy1215]

I only know the HWND as an input, first I use GetWindowThreadProcessId to get the process ID. But then how can I convert the process ID as the first input parameter of TerminateProcess which is HANDLE?

DWORD dwProcessID = 0;
::GetWindowThreadProcessId(hWndGot, &dwProcessID);

Thanks in advance!

Use OpenProcess function.

Did you read about using TerminateProcess in MSDN?
Doesn't any "clean" way to close a process work?
If the HWND you refer to is the handle of the main window - why not just PostMessage WM_CLOSE to it?

It's kind of you to remind me of closing the process in a 'clean' way. Because the HWND is not the main window of the process, so I have to use TerminateProcess.
So I should use the code below to TerminateProcess? for I'm not sure. Thanks.

HANDLE hProcess = NULL;
hProcess = ::OpenProcess(0, 0, dwProcessID);
if (hProcess)
{
	::TerminateProcess(hProcess, 0);
	::CloseHandle(hProcess);
}

Not really. Given a window handle use GetWindowThreadProcessID to retrieve its processId. From there you can use the ModuleTest code in the following link to politely close the process.

Thanks for your quick reply.
But I can't find the ModuleTest in the link(http://msdn.microsoft.com/en-us/libr...22(VS.85).aspx). Sorry!

Yes, you can terminate process by this way, you need only to use PROCESS_TERMINATE as first OpenProcess parameter.

Sorry, my mistake. I've updated the link above.
