问题 I have a problem while cleaning up my WebGl-Scenes. I'm using Three.js with a WebGlRenderer. In my application I have to change the views quite often and therefore need to render new scenes all the time. Uptil now I destroy and reinitialize the entire Threejs scene. After switching the scenes about 15 - 20 times I get following warning: WARNING: Too many active WebGL contexts. Oldest context will be lost. After switching a couple of times more the context is lost completly and the application

问题 I have a form to upload different kind of files. I need to ask questions according to the uploaded file type. For instance, if the file is a pdf, I need to ask the author. If the file is an mp3, I need to ask the title of the song. So : the user uploads the file which is saved somewhere on the server; the user answers the questions associated to the file type; the user clicks the Save button (the answers are validated) to confirm everything. Everything is fine so far. Now what if the user

问题 Can we work together to come up with something that works for control-c, control-break, log off, window X button pressed, etc? Here is what I have so far: class Program { private static ConsoleEventHandlerDelegate consoleHandler; delegate bool ConsoleEventHandlerDelegate(CtrlTypes eventCode); static void Main(string[] args) { consoleHandler = new ConsoleEventHandlerDelegate(ConsoleCtrlCheck); SetConsoleCtrlHandler(consoleHandler, true); System.Diagnostics.Process.GetCurrentProcess().Exited +=

问题 Does NUnit support the concept of an Assembly Teardown similar to the Microsoft.VisualStudio.TestTools.UnitTesting.AssemblyCleanupAttribute that can be applied to a static method? This would be run after all the tests within the assembly have completed. I am currently using NUnit 2.6.0. 回答1: It turns out this functionality does exist in NUnit it is just not very obvious or intuitive. According to Charlie Poole in the feature request I made for this functionality here, he states the following

问题 In Ruby, I have a DAO class, which is extended by a class that makes managing the connections easier, which is extended by a class that represents and manipulates data in a DB, which is further extended by another class. To use an animal metaphor it would look like this: class Animal ... end class Mammal < Animal ... end class Feline < Mammal ... end class Cat < Feline ... end class Lion < Cat ... end ... In PHP, there is __destruct method that runs when you destroy/delete a class. And should

问题 Is there anything standardized within the Scala library to support the disposable resource pattern ? I mean something similar to that supported by C# and .NET just to mention one. For example does official Scala library provide something like this: trait Disposable { def dispose() } class Resource extends Disposable using (new Resource) { r => } Note: I'm aware of this article «Scala finally block closing/flushing resource» but it seems not integrated within the standard lib 回答1: At this time

问题 I'm having problems with my .net controls not getting cleaned up properly when wrapped for activeX use. The default behavior leaves the SDK's test container app (TstCon32.exe) running as a GUIless process when I try and close it. The workaround I initially found via google was to override WndProc and call Environment.Exit(0) manually. This did get TstCon32.exe to shut down completely; however it's breaking the application where i need to have the control hosted. The App is MDI and WM_DESTROY

问题 For the snippet below, the deferred call is not made when ^C is received. Is it possible that the cleanup introduces a race condition? If yes, what could be a better pattern of cleanup on receiving an interrupt? func fn() { // some code defer cleanup() go func() { c := make(chan os.Signal, 1) signal.Notify(c, os.Interrupt) // Block until a signal is received. _ = <-c cleanup() } for { // Infinite loop. Returns iff an error is encountered in the // body } } 回答1: Note that if you "install" your

问题 If I set a variable using CreateObject() , do I need to clean it up by setting it to Nothing after use? Dim foo Set foo = CreateObject("SomeAssembly") foo Bar Set foo = Nothing I just found this post by Eric Lippert: The script engine will automatically clear those variables when they go out of scope, so clearing them the statement before they go out of scope seems to be pointless. 回答1: If I set a variable using CreateObject(), do I need to clean it up by setting it to Nothing after use?
