Hey everyone,

I was just wondering if there is a method as part of the JTree class that would accept a parameter such as an instance of DefaultMutableTreeNode and change the content of the tree...

Worked perfect, thanks.

I'm not sure about SCTP, but java is able to use Sockets to listen on a specified port, using either UDP or TCP protocols. If this is sufficient, then I would suggest googling "Java Socket...

I think a segmentation fault occurs when you are trying to use a memory location that it is not allowed to. For example, trying to write to a read only memory location or maybe even trying to use a...

Ok, thanks a lot.

Actually, can you use sprintf like this, and is it safe?


int len;
len = sprintf(NULL,"This is my forename: %s",fname);


And then use len to allocate the memory for msg?

Yeah, I assumed so. But what is the best way to go about doing this? What kind of practices do you use when dealing with such things?

Hey all,
I was just wondering, is it safe to do something like this?


char *msg;
sprintf(msg,"Forename: %s", fname); //where fname has been previously defined as char fname[ ] = "Jonathon";

...

Thanks, it works perfectly.
Is this "2>" a g++ functionality or an OS functionality? I.e. will the same command work on Unix i.e.

g++ "~/HelloWorld.cpp" 2> "~/out.txt"


Cheers.

This is not a question about C/C++ as such, but I couldn't think of where else to put it.

Yeah I have tried that but it didn't seem to work either. The thread idea sounds cool but a little much work for such a simple task.

We would need a little more information than that to help you. Is it a console application? or a GUI? Windows? Linux? Can you post any code so we can see exactly what you are trying to get at?

You could try reading the whole file into memory and store it in a character array i.e. char*. Then you could use the function strtok() to "tokenise" the character array, i.e. split up the character...

Doesn't the translate function simply move an object i.e. in your example so far in a specified direction? I don't think it's what I'm after, thanks anyway. I think it could be something along the...

Its not a problem. My point is that I cannot start off by just writing code because there is a specific function that I need to do it. I am just asking if there exists a function that would set the...

What attitude? I'm simply stating that I cannot in this case just "have a stab" at it which is why I posted the question I did.. and a somewhat useless reply is not helpful. I am well aware of the...

How about..

Nevermind, I have found the mistake.. I was using closedir() inside the loop where I should have been using it outside the loop.

I have tried the @ to suppress warnings on all the functions I am using, I don't get any messages from PHP but now all my function displays are the testing echos..

Ooh, Yes I see where its gone wrong now. I'm returning before Closing the Handle to the file. So really I should return pszFileText at the end, and obviously remove GlobalFree( pszFileText )..

Do you mean CloseHandle()?
