monitor

I have a folder called "Datas". This folder has a subfolder called "Inbox" inside of which there are multiple ".txt" files. This "Datas" folder can be modified and in the end there will be multiple subfolders with "Inbox" subfolders and ".txt" files. I need to monitor the "Datas" folder and the ".txt" file from the "Inbox" folder. How can I do that? INotify is just monitoring a folder and pops events when subfolders are created. How to pop events when ".txt" files are created (in which folder)? I need C or C++ code but I am stuck. I do not know how to solve this. Abhijeet Rastogi From the

Say I have an array of thousands of objects, and a small number of threads that might access each of the objects. I want to protect the access to one of the objects methods. Easiest way would be to declare that method as synchronized . However, that might result in creating thousands of monitors, whichever way they are implemented. If this were Win32, I'd never create thousands of kernel objects such as Mutex, but CRITICAL_SECTIONs might be plausible. I'm wondering what's the case in Java. Given the chance of contention is low, would the use of monitors impose more than the sheer amount of

I'm developing an application which will display information derived from the EDID blocks (monitor model, ID, S/N, etc.) on a dialog on the corresponding monitor. This code works for finding the EDID information for displays. It extracts the EDID information by enumerating the DISPLAY keys under HKLM\SYSTEM\CurrentControlSet\Enum\DISPLAY\[Monitor]\[PnPID]\Device Parameters\EDID . Update: The above code is relying on "side effects" of PnP use of the registry. I am now using the SetupAPI to enumerate monitors, which correctly handles monitors being attached/removed (unlike the code from the link

I have the Android Emulator running in my Ubuntu VM and just installed an apk file trough the console. The emulator and adb have many options to view what is going on on the device. But how can I get a list of services that are currently running? I'm trying to find out if a specific app installes a notify service to view (unwanted) ads. I even know the services' name. PS.: I'm an advanced beginner - but not advanced enough. So thanks for your help. You can get the list with the following command : adb shell dumpsys activity services If you just need a simple list without all the detail dumpsys

When reading articles about Java threads, I often notice the expression: "current thread is the owner of this object's monitor". I get the meaning: the thread gets the right to operate on the object. But I am puzzled why we use the phrase "the object's monitor" instead of "the object's lock"? In brief, I don't know the meaning of the word 'monitor' The question may be strange and simple. But I wish anybody can help to solve it. 3ks but I am puzzled why use word "the object's monitor" instend of "the object's lock"? See ulmangt's answer for links that explain the term "monitor" as used in this

I have developed a generic producer-consumer queue which pulses by Monitor in the following way: the enqueue : public void EnqueueTask(T task) { _workerQueue.Enqueue(task); Monitor.Pulse(_locker); } the dequeue: private T Dequeue() { T dequeueItem; if (_workerQueue.Count > 0) { _workerQueue.TryDequeue(out dequeueItem); if(dequeueItem!=null) return dequeueItem; } while (_workerQueue.Count == 0) { Monitor.Wait(_locker); } _workerQueue.TryDequeue(out dequeueItem); return dequeueItem; } the wait section produces the following SynchronizationLockException : "object synchronization method was called

I need some kind of event from Windows whenever there is a monitor that's getting plugged into system. Is there any API in Windows to do that. BTW, it is an C++ application Use RegisterDeviceNotification to register for getting WM_DEVICECHANGE notification. Goz You can do it via WMI, AFAIK. I've never tried it though so I can't give much help Read here for more info: MSDN - Receiving a WMI Event 来源： https://stackoverflow.com/questions/1440285/how-to-detect-hot-plugging-of-monitor-in-a-win32-application
