C++ :: Loading File Crashing Multiplayer Game?
Sep 4, 2014I've been making a multilayer game for a while and have a config that the game loads for the IP and stuff. I just recently put all the loading stuff into a function just so its easier to go through the code, but now the game isn't really working. It works fine on my computer connecting to the server myself, but when someone else tries to do it it seems like the game is working like it says the IP and everything from the config. When it tries to connect it either doesn't work or crashes just saying the program stopped working. Here is the code... I don't know if this is what is causing it to not work or something else.
string LoadConfig(int &loadPort, bool &fullscreen) {
string file;
string loadIP;
vector<string> fileLines;
fstream config("config.txt");
if (config.good()) {

C/C++ :: Client To Client Communication Using Network Programming?
Feb 8, 2015I am trying to make kind of a messenger using Socket/Network Programming
My program should allow clients to register or sign in, after they are signed in they should see a list of the other signed in people whoever I select from that list I should be able to implement using multiple threads as well.
I have done this much:
User.txt file
ahsan,1234
bilal,1234
pappu,1234
babu,1234
Client.c
#include <stdio.h>
#include <string.h>

#include <netinet/in.h>
#include <arpa/inet.h>
#include <stdlib.h>
#include <unistd.h>
#include <pthread.h>
[code]....
Now issue is in this code I am getting error SEGEMENTATION ERROR, CORE DUMP

C++ :: Code Reading From Online Dictionary Rather Than Offline Txt File?
Aug 14, 2014I have a script that checks and compares two lists from an offline dictionary. Dictionary.txt which has a lot of words in it. input.txt will compare to dictionary.txt and print out anything that matches in CMD.
However, instead of using an offline dictionary is there anyway to make a code check an online dictionary? If so, would this process be slow or fast?
C# :: Create Online Application Without Revealing Database Credentials
Jan 26, 2014I want to make an online application which will connect to my database to do the stuff, but I don't want the credentials to be stored somewhere in the program or in an external file somewhere in the computer or hardcored in anyway in the code.
I think that a good solution is (but I don't know how to implement it): on program execution, the credentials will be downloaded from my website somehow in an encrypted type maybe, from an api or so.
I've not tried before to make an online application, it's the first time. But I do have knowledge of SQL and PHP and I want to try a project like this.
The technology I am going to or can use is:
* Visual C# (in Visual Studio 2010 Ultimate)
* MySQL Connector/NET
* MySQL Database on a shared host
* PHP (if needed)
C Sharp :: Coding For Quantities In Online Shopping Carts?
Jan 11, 2013I am trying to create an on-line product store. I'm having trouble with setting up the code to correctly acknowledge quantity desired per product item in the shopping cart at check-out. I want to be able to capture multiple impressions/hits/clicks per item and increase the # in the quantity box each time someone clicks on the same item. For example, if product A is clicked 3 times, then the quantity in the shopping cart should show "3". If it's clicked 5 times, it should show "5" and so on ... However, right now, it's showing the product multiple times in the shopping cart with a quantity of "1" for each time the item was clicked. How can I correct this?

C++ :: Method To Loop Through Network IPs
Nov 25, 2013This problem relates to a program i am developing to ping all hosts on a network.
So far I've managed to access a PostgreSQL database to retrieve a CIDR network address e.g. 192.168.52.14/24.
I have then managed to mask the bits to get the network address.
So for e.g. above its 192.168.52.0
I now need some kind of algorithm to loop through available hosts so from.
192.168.52.0 - 192.168.52.255
I have got as far as deriving the network and separating it into an int array
So I have : ip_start[]= {192,168,52,0}
C++ :: Threading Over The Network With Pthread Or TBB?
Jun 13, 2013I'm wondering if there is a library for C++ that supports threading over the network, maybe with a threading pool and a specific protocol; or if there is just a de-facto protocol for doing threading over the network.

C# :: Difference When Starting A Program From Network?
Aug 17, 2012The following code prevents windows from letting the monitor go into sleep mode when the program is active and wakes the monitor up after a scanner scans something.
Code:
protected override void WndProc(ref Message m) {
if (m.Msg == W32.Const.WM_SYSCOMMAND &&
(m.WParam.ToInt32() & 0xfff0) == W32.Const.SC_MONITORPOWER && m.LParam.ToInt32() != -1)
{
return;
[Code] ....
When the program is started normally it works fine. But when the program is started from a network share it goes to sleep anyway and the OnScan does not work anymore. Removing the Send Message line makes On Scan work again but then the monitor wont wake up on a scan of course.
What could be the problem here when started from the network?

Feb 3, 2015I want to build a proxy, middleman between various client programs on my machine and servers outside, like this:
Client -> Proxy -> Server, Client <- Proxy <- Server.
OSes are Windows XP, 7 and 8.
Within that proxy I want to analyze data before it reaches it's destination and have full control over it to the point where I can prevent a packet from reaching it's destination if my program finds something suspisious going on. I need incoming and outgoing traffic of specific adresses and ports to be forwarded into my application on my client machine. My app then should deliver packets to their destination after they were analyzed.
The parts where data is received, analyzed, manipulated if needed, and sent is something I could code with no difficulty. But the concept of redirecting and forwarding is hard for me to grasp at the moment. I'd like to know at least what winsock functions I have to use.
If it's possible, I would like to use Windows libraries only, nothing from 3rd parties.
C# :: Mapped Network Drive - Deleting Or Moving A File
Sep 16, 2014Currently I'm trying to do something extremely basic: delete or move a file
I have a mapped network drive (Y) where I have a file I need to move from one folder to another
First was doing the obvious:
System.IO.File.Move("Y:TempFile.txt", "Y:Temp2File.txt");
Not much to go wrong here, right? As long as I have the correct permission to write in the folders and the folders exists, this would normally go smooth. But for some reason it only copies the file. The source file still exists, but it has successfully copied the file to the destination folder. No exceptions has been thrown or anything... but the file still exists in the source directory
I then changed the code to the following:
System.IO.File.Copy("Y:TempFile.txt", "Y:Temp2File.txt");
System.IO.File.Delete("Y:TempFile.txt");
Console.WriteLine("See mommy, no Exceptions");
As expected the file copies correctly, but the delete command is completely ignored. The file is not deleted, but the Console.WriteLine command is called
I'm running the application as the logged in user. The user has permission to delete the file. If I try from Windows Explorer, the file is correctly deleted. Unfortunately my application refuses to delete the file and even worse, it will not even throw an Exception.

Sep 10, 2014I basically want to develop an application which print an existing file on reception of a network event (application will be running on a seven 64 bits PC).
I wonder which application type would be the most suitable (and the simplest) for that (console win32, win32 app, MFC app ...). As this application does not need user intervention (print on network event), I'm not sure that I need a MFC application or a win32 app.
C++ :: Game Design Practice For Accessing Container Of Game Objects
Dec 21, 2014I'm working on my first video game. So far I have a few classes in the game starting with the Game class which includes a list of GameObjects (another class). There are several classes that inherit from GameObjects used to implement things like bullets, explosions, various enemy types, etc.
The game essentially iterates through the list of GameObjects to update/render them. I would like to provide access to the Game's list of GameObjects inside another class (like the Bullet class) so I can put new objects on the list. For example, when a bullet hits, I want to add an explosion to the Game's GameObject list it can be updated/rendered.
How this should be setup? I was considering adding a pointer to the Game or GameObject list to the GameObject class (and methods to access it), but I was wondering if there is a better way to set this up?
