• why we can't initialize a servlet using constructor itself?

  - by Reddy

  Why do we have to override init() method in Servlets while we can do the initialization in the constructor and have web container call the constructor passing ServletConfig reference to servlet while calling constructor? Ofcourse container has to use reflection for this but container has to use reflection anyway to call a simple no-arg constructor

• Delphi - Is there any equivalent to C# lock?

  - by CaldonCZE

  I'm writing a multi-threaded application in Delphi and need to use something to protect shared resources. In C# I'd use the "lock" keyword: private someMethod() { lock(mySharedObj) { //...do something with mySharedObj } } In Delphi I couldn't find anything similar, I found just TThread.Synchronize(someMethod) method, which prevents potential conflicts by calling someMethod in main VCL thread, but it isn't exactly what I want to do.... Edit: I'm using Delphi 6

• How to do method chaining in Java? o.m1().m2().m3().m4()

  - by Pentium10

  Maybe the title might be better, if someone knows a better one, please edit. I've seen in many Java code notation that after a method we call another, here is an example. Toast.makeText(text).setGravity(Gravity.TOP, 0, 0).setView(layout).show(); As you see after calling makeText on the return we call setGravity and so far. How can I do this with my own classes? Do I have to do anything special?

• Why doesn't HashTable.Contains() just simply return false if it is passed a null?

  - by Nate Pinchot

  I understand why passing a null to HashTable.Contains() doesn't work, but I don't understand what the point of it throwing an ArgumentNullException is - instead of just simply returning false? What is the benefit of throwing the exception (other than to make me do null checks before calling .Contains())? Caused By [System.ArgumentNullException] Key cannot be null. Parameter name: key at System.Collections.Hashtable.ContainsKey(Object key) at System.Collections.Hashtable.Contains(Object key)

• In C# ,how do I terminate a thread that has had its call stack corrupted?

  - by Emil D

  I have a thread in my application that is running code that can potentially cause call stack corruption ( my application is a testing tool for dlls ). Assuming that I have a method of detecting if the child thread is misbehaving, how would I terminate it? From what I read, calling Thread.Abort() on the misbehaving thread would be equivalent to raising an exception inside it.I fear that that not be a good idea, provided the call stack of the thread might be corrupted.Any suggestions?

• c# 3.5 class List<int> class initialisation

  - by josephj1989

  I can initialize a List like new List{1,2,3,4,5}; However List does not have a constructor which accepts a single parameter. So I tried to run this through the debugger and it seems to be calling the Add method. So how does the compiler know which method to invoke to add each individual element. This may be a silly question but I am a bit confused. Thanks

• Play an AudioBufferSourceNode twice?

  - by alltom

  Should I be able to use the same AudioBufferSourceNode to play a sound multiple times? For some reason, calling noteGrainOn a second time doesn't play audio, even with an intervening noteOff. This code only plays the sound once: var node = audioContext.createBufferSource() node.buffer = audioBuffer node.connect(audioContext.destination) var now = audioContext.currentTime node.noteGrainOn(now, 0, 2) node.noteOff(now + 2) node.noteGrainOn(now + 3, 0, 2) node.noteOff(now + 5)

• Is this technically thread safe despite being mutable?

  - by Finbarr

  Yes, the private member variable bar should be final right? But actually, in this instance, it is an atomic operation to simply read the value of an int. So is this technically thread safe? class foo { private int bar; public foo(int bar) { this.bar = bar; } public int getBar() { return bar; } } // assume infinite number of threads repeatedly calling getBar on the same instance of foo.

  - by Daniel

  I have a ocnnection to SQL Server set up in my vba code. The format is: strConn = "ODBC;Driver=SQL;Server=SQL1;Database=DB1;Uid=1;Pwd=1" I have this in 4 sheets, but there will be times when I will want to change it to call from SQL2 or SQL3, and instead of changing the code on each sheet 4 times, I want to change it only once. Is there a way to set up that line to run by calling it from somewhere else or by passing in a string into the ""?
