It's ok my question is already answered here: http://cboard.cprogramming.com/showthread.php?t=110612 in post #5. Sorry for the repost

Hi,

I am writing some code to parse a port range given as a...

ok thanks for all the replies everyone, I understand now, I should have been using strlen() for one. Just for completeness, the code is below.

Hi,

I'm experimenting with argv to learn more about how it works for a program I'm writing. I'm working with the code below:



#include<stdio.h>

int main( int argc, char **argv)
{

At first glance, you aren't updating C after each switch statement. For example, you enter 'A', and you add a number to the list, then the program breaks and loops back around to the A case again....

Well I tried compiling and running it, but it wasn't happening. I got no packets at all. I know nothing about raw sockets, but I can't see how you can be reading from anything anyway, you read an ip...

So would the following code be ok?



#include<stdio.h>
#include<stdlib.h>

void doStuff( void *sock );

int main()

Sorry I got that link wrong, it's www.security-freak.net. My bad.

sorry excuse my laziness, I realised I just needed a few printf statements to find out what's happening. So it uses pointers with whatever value t has at that point, which is necessary because that's...

if you are interested in learning more about socket programming, especially raw sockets, www.securityfreak.net is a really excellent site for that stuff.

Hi,

I'm looking up pthreads and it's going ok, but I'm getting a little confused with the (void *) casting, so I was hoping sombody could explain what exactly the variable t is when it is passed...

Here is the header file and some of the source file, if you want to see more code just ask.

I moved it into the source file but then I get these errors

Yeah sorry forgot those lines. I added them but then I get errors during linking as far as I can tell.

Well, your test example above works fine for me. But when I declare the two arrays outside the class like yours I still get errors, and member functions apparently can't see them



In file...

Thanks for the replies. I'm still getting errors compiling after making the changes however

Hi,

I am writing a simple chat program using Qt4. I decided to convert all text which is sent over the network into morse code as a side task to better understand string manipulation. I am having...

I was always under the impression that most packets had it set to 256 as it's only used to stop infinite routing loops which are relatively rare afaik. I don't think it has much practical use in...

ok I just tried it with QTextStream and it worked! Thank you so much, you have no idea how long I have been fighting with this, seriously thanks a lot.

Well, the examples simply read into a qstring and they work fine, but you are right the datastream is for binary writing, I want to try this but what type of variable should I use, will an arry work...

Hi,

I am using Qt4 to develop a simple chat client for school. I have already asked this question on qtforums.org but never got a response, I am hoping that someone here has some knowledge of Qt...

It's me who is writing/designing this program. Thanks for the links, I'll have a look. I thought there was a set method to writing designs but choosing your own is great and should be easier.

Hi,

I need to write the deign for a program which I am writing for a school project. I am using qt4 for the gui so there will be around 3-4 source files. This is my first time writing a design for...

Hi,

I am trying to get my head around windows sockets, however they are proving to be a lot more complex than in linux. So I decided to see just how much I would need to modify a simple echo...

Actually after a little research I realise that forking is really not done on windows, I'm better off with multithreading.
