如何知道我的某一个进程正在运行？

[uk]

有什么比较高效的方法吗？

使用FINDWINDOW（）

[scklotz]

在你的程序里建立一个信号量或则mutex,
然后就可以监测到.

create a named CMutex in your program, to detect the existence of your, program, you can try to do the samething , if success, no previous instance exists, otherwise there is a previous instance running.

我想知道程序启动时他会向系统发送一个什么消息，这样我就不用枚举系统里所有的进程信息了，那样太慢了。
各位能谈谈CMutex具体做法吗？我很急，谢谢各位！

// CPreviousInstance.h

class CPreviousInstance
{
public:
CPreviousInstance();
virtual ~CPreviousInstance();

LONG Count() const
{
return m_previous;
}

private:
static LONG s_count;
LONG m_previous;

CPreviousInstance(const CPreviousInstance&);
CPreviousInstance& operator=(const CPreviousInstance&);
};

// CPreviousInstance.cpp

// static instance count stored in a shared read/write section

#pragma data_seg("Instance")

LONG CPreviousInstance::s_count = 0;

#pragma data_seg()
#pragma comment(linker,"/section:Instance,rws")


// Construction/Destruction

CPreviousInstance::CPreviousInstance():
m_previous(0)
{
m_previous = ::InterlockedIncrement(&s_count);
--m_previous;
}

CPreviousInstance::~CPreviousInstance()
{
::InterlockedDecrement(&s_count);
}

用个特殊的类名称，直接FindWindow就行了。

还是用vss自带的“Process Viewer"吧，这个最省事！
你可以观察当前正在运行的所有进程！

Process Viewer 也不能实时刷新
