The OpenDNS community appears to be using it. Is anyone familiar with this software? What's it like to customize and maintain? Would you ...

Question about the Java Garbage Collector, nulls and memory leaking.

Suppose I'm implementing a queue in java and I have a reference to the initial node, called ini and another to the last one, called last. Now, I start inserting objects into the queue. At one point, I decide I want an operation to clear the queue. Then I do this: ini = null; last = null; Am I leaking memory? The nodes between ini and ...

Should one always keep a reference to a running Thread object in C#?

Or is it okay to do something like this: new Thread( new ThreadStart( delegate { DoSomething(); } ) ).Start(); ? I seem to recall that under such a scenario, the Thread object would be garbage collected, but the underlying OS thread would continue to run until the end of the delegate passed into it. I'm basically looking for ThreadPo...

VBA Reference Libraries

Hi, I'm new to VBA and have been throwing together a small macro application for the Office. We've got about 80 users on essentially identical PC setups, and it will be accessed by all but a few users.

C++ How can I get a return a reference and save the refence as a local variable in a function?

I have a function inside a class that returns a reference to a member variable. std::vector<uint8> & getBuffer() const { return m_myBuffer; } Now say in another class I call this method: int someFunction() { std::vector<uint8> myFileBuffer = myFile.getBuffer(); } This line calls the copy constructor of vector and makes me a l...

What is the difference between a C# Reference and a Pointer?

Sorry for such a newbie question but there is something I do not quite understand the difference between a C# reference and a pointer. They both point to a place in memory don't they? The only difference I can figure out is that pointers are not as clever, cannot point to anything on the heap, are exempt from garbage collection, and can ...

How do I use an equivalent to C++ reference parameters in Java?

Suppose I have this in C++: void test(int &i, int &j) { ++i; ++j; } The values are altered inside the function and then used outside. How could I write a code that does the same in Java? I imagine I could return a class that encapsulates both values, but that seems really cumbersome. ...

Framework + Client Code references

There are several things I'd like, and I am wondering if they are all possible: (.NET 3.5, VS2008) Have a .sln with only the implementation (tool) - project Have a .sln with tool + framework projects Have a .sln with only f...

Does Ruby support var references like PHP?

In PHP, you can make two variables point to the same data. $a = 'foo'; $b = 'bar'; $a =& $b; echo $a // Outputs: bar echo $b // Outputs: bar What we are trying to do in Ruby is set @app_session to be equal to session[@current_app[:uid]]. So we only have to deal with @app_session in our app, and everything is automatically saved to th...

Will this lead to a memory leak in C++?

Hello, I have a C++ memory management doubt, that's (obviously) related to references and pointers. Suppose I have a class Class with a method my_method: OtherClass& Class::my_method( ... ) { OtherClass* other_object = new OtherClass( ... ); return *other_object; } Meanwhile in a nearby piece of code: { Class m( ... ); ...

In C#, where should I keep my timer's reference?

The documentation of System.Threading.Timer says that I should keep a live reference for it to avoid it being garbage collected. But where should I do that? My main is very simple that I don't know where to keep the reference: class Program { static void Main() { new System.Threading.Thread(myThreadStart).Start(); ne...

Java, pass-by-value, reference variables

Hello, I have a problem with understanding the "pass-by-value" action of Java in the following example: public class Numbers { static int[] s_ccc = {7}; static int[] t_ccc = {7}; public static void calculate(int[] b, int[] c) { System.out.println("s_ccc[0] = " + s_ccc[0]); // 7 System.out.println("t_ccc[0] = " ...

VBA - "Can't find Project or Library" for standard VBA functions

So I'm having to run someone else's excel app on my PC, and I'm getting "Can't find Project or Library" on standard functions such as date, format, hex, mid, etc. Some research indicates that if I prefix these functions with "VBA." as in "VBA.Date" then it'll work fine. Webpages suggest it has to do with my project references on my sys...
