C/C++ :: Code For A Server That Creates A Log File
Mar 12, 2013
I am trying to write a c code for a server that recieve msgs from a client and put that msg in a log file dedicated for that client along with the msg reception time and client IP address.......
The log file must be created if it doesn't already exist.....
Here is a code that i wnat to customize and it already opens a communication channel between server and client......
Here is my code:
#include "stdio.h"
#include "stdlib.h"
#include "sys/socket.h"
#include "sys/types.h"
#include "netinet/in.h"
#include "error.h"
[Code] ....

Here is my issue: I am making a simple audioplayer in Xamarin.android but i want every time i change the track to make a crossfade effect. So im using 2 mediaplayers at the same time for the fade. The problem is that im defining one time the players and i pass the player as a parameter like this:
public MediaPlayer player = null;
public MediaPlayer player2 = null;
....
If i have to fadeout the player and start the next one im doing it like this:
if (player != null){
if (player.IsPlaying) {
cts = new CancellationTokenSource();
token = cts.Token;
FadeOut (player, 2000 ,token);
[Code] .....
So my problmem is that player and player2 remain always null. Why? i guess c# creates a copy of player and player2 and use this one. How i can pass a mediaplayer as parameter and always use only player and player2?

I am relatively new to C++ and am trying to bubble sort my linked list that creates 100 random integers. Everything works, but I am unsure how to continue this to include a bubble sorting method.

I am working on a program which creates a large pointer array of numbers and then performs several iterations of operations in them.
Code:
int * u = new int[N];
double * nu = new double[N];
int * nud = new int[N];
for (int i=0;i<M;i++){
for (int i=0;i<N;i++){
u[i]=0;
nu[i]=0;
[Code]...
If M is small enough then there are no problems in the program. However once M is large enough I get the "unhanded exception":
std::bad_alloc at memory location 0x0026f728..
Since I am just reusing the same arrays, and since I am able to make it through a few iterations, I didn't think it could be a memory issue. If it is, is there a way I can clear the data completely after each iteration?

I have to make a server-client file transfer using UDP . I have created a basic server which receives message sent by client . That's all. Now comes the major part :-
1. The message sent by client is the name of file
.2. Now the server checks whether there exists this file or not .
3. If there exists it sends the file to the client and it also keeps the count of the number of requests of file made by the client . Here is the Server Code
Code:
#include<sys/socket.h>
#include<arpa/inet.h>
#include<stdio.h>
#include<unistd.h>
#include<fcntl.h>
#include<sys/types.h>
#include<string.h>
}
[code]...
The server reads the data from file and writes into it and send to the client , On the other end client receive the data and make duplicate of this file and write into it. But on compiling it gives error in reading the file.

I'm trying to upload a file to a FTP server with curl. The problem is that I do not know what to do after I enter the passive mode and open the specified port. I tried to send data with curl_easy_send but it simply hangs.
bool Ftp::Upload(const char *local_fn,const char *remote_fn)
{
int ret;
string ip;
unsigned port;
SendCmd("TYPE I");
// Enter passive mode and get IP & port
if(pasv(ip,port)==false)
return false;
[Code]...
How to send file to the server. And I also suspect I should tell the file size to the server.

Here is what I got so far, I am not able to send whats in the txt file to the server. Its pretty much a txt file with movie names and when the client types the name, it brings up the movie and its ranking (all from the txt file)
Server Code::
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <arpa/inet.h>
#include <string.h>
#include <fcntl.h> //file control
[Code] .....
I attached the images of the client and server when I run this, along with the movie.txt file. I cannot seem to get the file to send to the client?

I have done a test, I have edited with the WordPad in Windows on my Local Webserver a file banana.h which contains a list of float arrays in order to extract one array and create a text file named ObjVerts.txt I have done a lot of search in the Web in order to find a small piece of code that can read the text file and convert it to a float array GLfloat, but I did not find any. I have found a lot of piece of code that read the file and make a NSData but many of the code seem to not work. It seem that the last statement return nothing!
NSURL *myurl = [NSURL URLWithString:@"http://localhost/ObjVerts.txt"];
//NSString *mystring = [NSString stringWithContentsOfURL:myurl];
NSData *mydata = [NSData dataWithContentsOfURL:myurl];

I want to write a single line to a file and upload it as a .txt file to a server directory . I know the traditional way to upload a local file to a server
public bool ftpTransfer(string fileName){
try {
string ftpAddress = "test.com";
string username = "test";
string password = "test";
[Code] ....
is there anyway to change this so that I can write the contents of the file through the program and upload it directly without having a local file?

Currently I'm working on a application which reads the input from the server and write to a file. Message stored in server : idle_message="维杰PC时钟" key_prompt="在按键"
Server will send a xml reply with encode type as "UTF-8". In my code I'm store in a char array. [ char * ch = "idle_message="缁存澃PC鏃堕挓" key_prompt="鍦ㄦ寜閿" msg came from server and copied from vs2005 watch point] After this I'm writing the same to a file in my desk using the API WriteFile. When i open the file in Editplus below is the content.
idle_message="维杰PC时钟" key_prompt="在按键" Again I'm trying to read the file and storing into the char array. Below is the content viewed by the watchpoint in VS2005.
idle_message="缁存澃PC鏃堕挓" key_prompt="鍦ㄦ寜閿? I'm trying to find the starting and ending chinese char and I'm converting that char to wchar_t using the API mcstowcs() for display, its coming as completely junk chars.
I can able to every place the chinese char are different. how to overcome this problem.

I have a client/server program. My Client process spawns my server process using a `fork()` and `system()` call. The client and the server are meant to communicate to each other through named piped, that is a requirement of my homework. The client and the server are supposed to initially send a message to the other one, through a pipe, to confirm that a connection is made. My issue is that my client is trying to open one of the named pipes before the server has a chance to make it. This doesn't always happen though. Occasionally, it will run fine. Is there some way to synchronize this?
My overall goal is to get a filename and search target from the user, send those to the server through a named pipe. And the server searches for the target and sends info back.
OUTPUT:
Client: PID 2986 - Running on Tue Sep 30 20:59:28 2014
Client: PID 2986 - Enter File Name: largeSampleText.txt
Server PID 2988 - Running on Tue Sep 30 20:59:32 2014
Server: PID 2988 - Synchronized to Client.//This means the client-to-server fifo is working
There was an error opening serverToClientfifo//This means client couldn't open the server-to-client fifo
error is: 2//This means the fifo doesn't exist yet
[Code] ....
CORRECT OUTPUT:
Client: PID 2542 - Running on Tue Sep 30 20:58:44 2014
Client: PID 2542 - Enter File Name: largeSampleText.txt
Server PID 2557 - Running on Tue Sep 30 20:58:54 2014
Server: PID 2557 - Synchronized to Client.
[Code] ....
RELEVANT CLIENT CODE:
int main() {
char requestedFileName[1024];
//Get initial information on the client
pid_t clientPID = getpid();
time_t currentTime = time(0);
char* stringTime= ctime(¤tTime);
[Code] ....
I tried creating both of my fifos in my client and my output changed to this
Client: PID 3150 - Running on Tue Sep 30 21:23:17 2014
Client: PID 3150 - Enter File Name: largeSampleText.txt
Client: PID 3150 - Enter Target:
Server PID 3153 - Running on Tue Sep 30 21:23:21 2014
was
Client: PID 3150 - Input File >>>largeSampleText.txt<<<
Client: PID 3150 - Target >>>was<<<
Client: PID 3150 - Synchronized to Server
Server received unexpected connection message
Message: was
Terminating
So It appears like the client went ahead and put `requestedFileName` and`requestedTarget`into the pipe and the server read out `requestedTarget` instead of the connection message. Not sure why though

i have to upload a ms access database file to the server from my client program. The server program should connect to this database and read the data. What's the easiest way to upload the file? Is it FTP? i tried sockets, but it only allows like 9kb of data transfer capacity.

I have a function in one src file called from code in a different src file.
In ig_cfunc.cpp
Code:
#include "ig_tools.h"
int x2_count = 0.0;
float rel_branch_degree_tmp = 0.0;
string type;
vector<int> is_disp_type;
[Code] ....
I am getting a linker error,
Code:
ig_cfunc.cpp:1609: error: `calc_rel_branch_degree' undeclared (first use this function)
I have deleted all of the objects and recompiled to make sure that everything is in sync. I can't see what the issue is here and I'm not sure what to do next. This code actually worked until I changed the name of the function, so the types are all correct and such. This is the format I use for all external functions ....

Here is program I have written which reads the destination, then finds it from a separate file, and reserves the information on a different file. But the reserved file has hex code information, how can I output my result to the file in normal alphabet/number/symbol characters? I've tried fputs,fprintf, and fwrite , and all give me the same result. The array c, is the one to be written to file.
void main {
FILE *afile = fopen("flightrecord.txt","r");
int i=0,j=0,k=0,z=0,y=0,sum=0,seat=0,g=0;
char destination[10],a[1000],c[1000],b[1000],name[100],last_name[100],c_number[15],plane[]={'P','6','2'};
printf("What is your destination?");
scanf("%s",&destination);

So the premise of my code is to read in a 2d array from a .txt. The array is a game board but the first two lines are what determine the size of the board. After i read it in i want it to find wherever te character "U" is, and then display the array but only showing U and whats around it. Problem is i cant get the array to print the right size and the code for displaying the U is not working either.
ifstream inputFile;
int boardSizeRow;
int boardSizeCol;
inputFile.open("C:UsersMichaelDesktopfileboard2.txt");
inputFile >> boardSizeRow;
inputFile >> boardSizeCol;
inputFile.get();
[Code]...

I use a programming language called layout which nobody here has probably ever heard of. It was discontinued over 15 years years ago but it was a very visual & easy to use piece of software - no coding required. In fact once you name all the variables on cards (forms) from then on it's just mouse clicking & occassionaly typing a number if required. It used blackboxes in a flowchart arrangement which were pre-done code for doing just about anything. i.e opening windows, handling numbers & text, files etc. I have written many programs with it including database management, quoting software & currently use it in my business to track my jobs & do invoicing & ordering. It's a pity it wasn't updated & still around today.

Back to the problem. Being a 16 bit program it was written to run on Windows 3.1 but still works on Windows 7!! as long as it is the 32 bit version. I need to write a program that will run on 64 bit W7 without resorting to using a virtual PC solution. I have tried to find something similar that I might be able to use instead but so far nothing comes close to Layout. I just remembered today that layout can produce not only .exe programs but also various versions of C/C++ including visual c++. So I got this idea that if I could get those files I might be able to stick them into a C compiler program to re-make a "modern" exe file.
I could just do a simple sample program & send the source code to them to see if it works on a 64 bit version of Windows 7. how I can do this myself to produce a working exe file.
