I understand I can do this via a php file on a server, but I don't understand how I can communicate with the php file from c++ code on my machine. Is there some library function I can use to load the html form or data object to hold the php form? Also whats the vibe on amazon EC2 cloud computing servers? It may be out of the scope of this simple program I have uploading and downloading XML, but is this the technology of the future, and should it be embraced now?

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 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"

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 <stdlib.h>
#include <unistd.h>
#include <arpa/inet.h>

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'm currently in the middle of designing a program for some project. one part of the program is to send reminding SMS messages to the employees.
I have already subscribed to a SMS provider that has SMS integration - API. But now I'm wondering how will I be able connect to the SMS server and be able to send messages?
I need to create a client and server program. The client will have a GUI that will display all the available servers (since more than one will be running) in a list box.
I’m guessing a TCP connection will be the best method here, but how will the client find the servers to connect to? I won’t know the IP address of the server because anyone could take the server program and run it on their computer and the client would have to find it.
Is there some way to make the server send some kind of signal that only the client application will be to connect to? So the server will be sending out a signal, the client finds the signal and connects to the server. Is this possible?
i also need to be able to store the IP address the client selects so when the client application is run again it will automatically connect to the server that was stored.
I need to connect and manipulate a DB in SQL Server 2008, but need to have high performance too, so, I want to develop an class in C++ that connect direct to DBMS, in a low level, without using ADO, ODBC or OLEDB.

I know this question must have been asked before, but the problem that I am facing is that I am using a library PoDoFo to parse PDF files. It seems that it is only compatible with C++.
Now I want the application to be web-based. That is, the user uploads a PDF file on the server, the server parses it and the parsed content is then sent back to the user.
Is such a thing possible with C++, or maybe any good work-arounds? Or should I look at server-side scripting languages like PHP and their respective libraries?
I am writing a very basic database in C++ and I am accessing the data from a web browser. I am using the opensource Mongoose web server code....
I have an issue...
The way the DB works is this: on starting, the DB loads a json file of all of the data into it. I have a class called DatabaseLoader that does this - it is the class that gets rewritten depending on the data structure of the json.
This is passed to vectors (vector<Node*> and vector<Edge*>) as references from Graph object.
Once the DatabaseLoader has finished it can be destroyed and any memory allocated objects it created (except the ones in those two vectors).
From then on, the Graph object is in charge of all of the elements in the database that are stored in the two vectors. When the user browses to htpp://127.0.0.1:8000 they see the json representing each object in the vectors.
All good so far....
However, when I repeatedly hit refresh in my browser (and call me insane...) at quite a fast speed I get this error:
Code:
main(29855,0x7fff76763310) malloc: *** error for object 0x7f98b2829408: incorrect checksum for freed object - object was probably modified after being freed.
*** set a breakpoint in malloc_error_break to debug
[1] 29855 abort ./main testing.json
It seems to me this would be if I tried to "delete" and object twice, or if one of my objects was overwriting memory somewhere. However I am not recreating anything, I am just looping over the vectors and printing out the content. When I refresh slowly, I dont see this happen - i did it quite a lot of times, but when I do it fast I think it is happening.
So is there any possibility of me hitting the c++ web server to quickly and it is trying to process the data twice, causing some sort of memory error - i.e do I need to implement threading or something??
I can paste code, but there is quite a lot now....
I just started to work on a project which is 'Body Area Network'.
What I need to do is to take data from body with some sensor nodes and send it to mobile which would further send the data to a remote server, and I need to add some security (encryption/decryption) on the data.
So I want to know how to send data from mobile after encrypting it to the server and then decrypt it back(on server side).

I would imagine there is a pretty big difference between retrieving text and downloading files but im just wondering what the best thing would be to research for both.
