I have learned how to work with TCP and UDP connections with the Java standard API but now I am trying to see how to create raw packets to send on a network with Java so that I can create the header...

it should be an iso image file, just burn that to a blank dvd for use. no need to unrar or unzip.

lets say I have a 1000 byte file and bytes 900-1000 are filled with data and I want to write to bytes 400-500, so I do that but everytime I do it resets the file size to 500 bytes killing the data...

I am trying to take a a file of fixed size and use seekp to jump to a particular spot in the file, write around 100 bytes or so but only to that part of the file while still keeping the size of the...

yeah that apfloat thing looks nice, thanks man.

Is this the best datatype to use for doing calculations for extremely large numbers such as computing pi . Or am I going to need to create my own algorithm for handling extremely large numbers? how...

Fixed it, Thanks for the help guys.

Im having a problem with the while loop in my code, if I change what X2 is being compared to to anything other than 0 it doesnt hit the while loop, I am hoping its just some weird mistake. Thanks in...

so in the end there has to be somekind of verification and exchange that is safe before the public key can be used. Thanks for the info.

I have been reading about public key encryption for the past day or2 and got thinking about something, and am hoping someone here can offer some insight. anyways here it goes

Since public key...

just take a look at box2d.org because thats a 2d rigid body physics engine and thats not all the math required for even just a 2d game nevermind a 3d game.

alright thanks for the advice ill continue on with that.

thats what I have been doing, I was just looking to do it with objects from structs but it doesnt matter anymore.

ok so just write a bootloader, which is the first thing an OS does is run the bootloader. And write it to the first sector on a clean hard drive or floppy disk and boot from that. You just need an...

yeah just make sure you structure your database file accordingly to how your program reads it.

do you have an OS for this Z80 pc, because if you dont than your going to be able to use your flat binary file that was created from your compile to be run. You dont need an exe file if there is no...

can the name possibly be a number or something, it has to be something that I can increment by 1 or something before I make another atom object, and yes I have used pointers like once or twice but...

I have it working with a bunch of vectors but I wanted to see if you can do it with objects from structs, im inexperienced with objects so I want to know how can you have the name of the object...

you could setup a little database which would just be a file and have the program open up the file and search it for the name, ahh what the heck ill show you what i mean, heres the code.

first...

I am trying to figure out for my physics simulator how to give my object name a variable or something, ill show an example and the compiler flags it an error but all i am trying to do is pass it the...

yeah gcc is for c and g++ for c++

how do i make it so that functions and procedures that are located in other files in the include statement have access to the global variables within main.cpp, thanks in advance.

ok that worked, wow thanks i feel like a complete noob, its my dumb VB6 class practices catching up with me lol.

When i compile this code i get an error which states

main.cpp|38|error: no match for call to ‘(std::vector<std::basic_string<char, std::char_traits<char>, std::allocator<char> >,...

yeah didn't realize it was that integer thing, thanks man.

that did absolutely nothing, but thanks for trying. I think the problem is that its not getting to the code for some reason maybe the while loop or something? i dunno but chris you prolly hit the...

what kind of assembly is it? if its x86 i got a good link to a free pdf download of an awesome intro to x86 assembly for you.

nah thanks but that didnt work

this is a really strange one since it doesn't make sense why the program just starts running then shuts down without executing the system("PAUSE") at the end.

here is the source code, thanks in...

that didnt help.

You messed up your if statement and forgot the braces on the if and else statements, heres the fixed code, good luck.


#include <iostream>
using namespace std;

int main()
{
double payrate;...

i wrote some code which only works with objects with a heading of 0 degrees right now because its not finished but when i run it it never seems to catch the collision and break the loop. I need some...

oh ok thanks

Ok here is the new code, and this math works when i follow it exactly with a calculator i get (0.707, 0.707) with the previously entered values in my first post. But in the program i get like .502...

yeah i realize the math is wrong and im changing that but the program still doesnt work

I am having a problem with the results that I am getting when I run my program, according to the math i wrote in the program when I enter these results

object's x co-ord = 0
object's y cor-ord =...

so your saying that if you have data as globals another separate program is allowed to manipulate that data easier? I thought it didnt matter where it was in RAM?

If you have multiple If statements happening to check the logic on something is it better to just use all else if's to make your code execute faster?

and I understand that people always say that...

ok thanks for ur help

is that a reference to the start of my vector?
