Another thing I would like to know is what exactly are the differences between the various C's? Is there specific purposes/situations each is better for?

Hi people,

For a school assignment, I have to create a Client/Server application in Java that uses sockets to communicate. All communications have to be in XML format. Now, the difficulty of the assignment is that we have never done Client/Server programing in Java up until now, so I'm kinda lost. I managed to set up pretty much everything except for the XML communication and I'm lost. I use the JDOM library to create a small XML document in my server, and I attempt to send it through a stream to the client. Now thing is, I'm not sure what I need to send. I have a Document object that I guess that I could send, but it's not really XML, it's an object so it can't be read by a say, a python client does it ? Do I actually have to create a file, send the file, delete the file just to send my xml to the client ? Can anyone give me a hint I'm really lost here. Would it be easier in another library ?

Unrelated to the above, does anyone know if there is any point to using dateTime vs dateTimeOffset?

DateTimeOffset has everything DateTime does and DateTimeOffset also supports timezones.

It would always be nice to also mention the language. If it's C#, I think I remember there being some pretty concrete advice on MSDN on this subject.

Can somebody give me a hint what is happening when I declare a struct variable like so (C++): "MyStruct *struct_name();" ?
I have no idea what is happening here

Edit: figured it out, that is actually a function declaration ^^. I am quite new to C++.

struct MyStruct{ };

struct MyStruct* MyFunction(args)

Woa java is driving me nuts today.
I have this endless loop:

boolean pause=true;
while (true) {
	if (!pause) {
		update();
	}
}

At the start of the program pause is set to true and is not changed in the class which contains the loop. It is only changed in another class, which contains a gui. And heres the weird part: pause gets set to false correctly, but the loop still doesnt run. However, if i add a System.out.println("foo"); inside the loop, it works. So my assumption is, java falsely "optimizes", aka removes, the loop, because the condition is never changed to true inside the class. How can i prevent that without adding dummy commands?

while (true) {
    if (!ClassB->queryPause(pause)) {
        update();
    }
}

boolean pause = true;

... do stuff with pause ...

public boolean queryPause(boolean pause)
{
    return pause;
}

Can you make it more like this?

Class A

while (true) {
    if (!ClassB->queryPause(pause)) {
        update();
    }
}

Class B

boolean pause = true;

... do stuff with pause ...

public boolean queryPause(boolean pause)
{
    return pause;
}

I think it would be even better if you had 3 classes. 2 that actually do stuff and have all the data and another one acting as an interface for the other two to communicate. This way you can easily shuffle stuff around and change things later.

while (true) {
	if (!B.getPause()) {
		update();
	}
}

boolean pause=true;
...
	public boolean getPause() {
		return pause;
	}

	public boolean getPause() {
		System.out.println("qwe");
		return pause;
	}
