问题 I have a crash dump from my app showing a bunch of threads waiting on a syncblk, and the syncblk shows that it has no owning thread. How is that possible? I'm trying to reproduce the symptom in a test app, and I can't figure out what could possibly happen to produce that result....having the owning thread exit or die without releasing the syncblk still shows up as owning the object, just the threadid is "XXX"....I've tested using fully managed graceful exit and hard thread termination via

问题 I'm writing a web application that will have "plugins". The plugins will be .DLL files which will export their functionality through predefined interfaces 'n stuff. All the .DLL files are in a folder called "Plugins", and the ASP.NET application loads them all upon startup (by using Assembly.LoadFrom). The problem is that when developing, these plugins will change fairly often (all the functionality is in the plugins, the website itself is just a skeleton). Thus, I need a way to automatically

问题 Currently we are analyzing a tomcat thread dump. A single thread dump of all threads running at that same time on a tomcat contains the following lines: ... "soldOutJmsConsumerContainer-1" prio=10 tid=0x00007f8409c14800 nid=0x231 in Object.wait() [0x00007f8403a9f000] java.lang.Thread.State: WAITING (on object monitor) at java.lang.Object.wait(Native Method) at java.lang.Object.wait(Object.java:485) at com.tc.object.RemoteObjectManagerImpl.waitUntilRunning(RemoteObjectManagerImpl.java:150) at

问题 Is there anyway using WMI/.Net to grab monitor information such as Manufacturer, Serial Number, Monitor Size etc.? Using a script is an option as well, or can I query the registry directly to get this information? SELECT * FROM Win32_DesktopMonitor doesn't really return any useful information for me in this case. 回答1: You may want to try this https://raw.githubusercontent.com/MaxAnderson95/Get-Monitor-Information/master/Get-Monitor.ps1 Cheers 回答2: Hey, I use this tool for a lot of my WMI work

问题 I am using WMI Win32_MonitorDesktop to get all the monitors information on the system. However it only returns one. I have tried it on several computers, and they definitely have multiple monitors on them, connected and working. ManagementObjectSearcher monitorObjectSearch = new ManagementObjectSearcher("SELECT * FROM Win32_DesktopMonitor"); foreach (ManagementObject monitor in monitorObjectSearch.Get()) { Debug.WriteLine(monitor["Description"]); } Does anyone know why i'm only getting 1

问题 I want to monitor the change of track in Rhythmbox using python. I want to continuously check for change of track and execute a set of functions if the track is changed. I have written a piece of code which gets hold of the Rhythmbox interfaces from the dbus and gets the current track details. But this program has to be run manually to check for any change. I am new to this and I would like to know how we can create a background process which continuously runs and checks Rhythmbox. I dont

问题 I saw a similar question which asked how to monitor the progress of a backup/restore operation: Is there a SQL script that I can use to determine the progress of a SQL Server backup or restore process? I would like to know if there's a similar query/way to see how much time the query has left until it will end. For example, one query usually has an elapsed time of 5 minutes. I would like to know how much time is left until it will end DURING the query's execution. 回答1: There is no way to know

问题 I'km working in Qt, i need help to get the physical size of the screen (monitor), In Qt one can get a QDesktopWidget from QApplication , I mean: QDesktopWidget *mydesk = QApplication::desktop(); The QDesktopwidget has some methods to get the resolution in pixels and some to get the the size in milimethers: mydesk-> widthMM(); mydesk->heightMM(); However, this does not correspond to the physical size, when I measure my screen with a ruler, there is a considerable difference. Also one can get

问题 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

问题 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
