I'm trying to send a simple text string using httpsendrequest, everything works fine, the string is sent but I don't know how to retrieve it in the PHP server. Also when I use internetreadfile, the dwBytesRead is 0 meaning that there is no response from the server though the application works fine. This is the code that I have so far.
#define _WIN32_WINNT 0x600
#include <stdio.h>
#include <wininet.h>
#define BUFLEN 200
static const char *acceptTypes[] = {"application/x-www-form-urlencoded", NULL};
static const char *postData = "teststr=Hello+world&testval=42";
int main() {
HINTERNET hSession, hConnect, hFile;
[code].....

I've been trying for more than one month to access a method found in a library called libcocosnas_static.a. I'm using Cocos2d-X version 2.0.4. The library has been used many times by my company to make games using cocos2d-1.0.1-x-0.12.0 without any problem.
This is what I've done:
1- I added the include paths of the library to both eclipse and Android.mk
2- Included the .h file using #include "NASPlatformUtil.h"
3- Added the libcocosnas_static.a file to the proj.androidobjlocalarmeabi folder
4- Added "LOCAL_WHOLE_STATIC_LIBRARIES += cocosnas_static" to the Android.mk file
5- Called the function using: NASPlatformUtil:: openUrl("http://xxx.xxx.com/");
I can right click on the function, click Open Declaration and get it without any problem, but the compiler keeps on giving me that dreaded error...

How do I do a get/post for an array in c#? In C#, you get and set variables like this:
public int ID { get; set; }
How would one get and set an array in C#?
This will not work:
public uint [5] BIG_Hash {get; set;}

I'm writing a small c++ program which will be able to do a few things with a matrix. I have a class called Matrix and a member function in it called getSor() which returns an integer value about the number of lines in the matrix. When I call this getSor() function the program says: error: request for member ‘getSor’ in ‘matrix’, which is of non-class type ‘Matrix*’
- 'matrix' is an existing Matrix object here
- I called the function like this: "cout << matrix.getSor() << endl;"

I'm building a project in my free time and in the last part of it I need to fill a form of a website and then 'hit submit', but how it can be done. Btw the form is a 'POST' form so it's harder than a 'GET' one.

i have a page (which i did not create) which opens as a modeless box with a save button. The save works great in saving comments. However the client wants to have the comments update on the page where the link is for the editable modeless box. is there a way to post pack to the original page to force the page to refresh the information?
info:
All information is gathered on the page load event.
there is a section that shows all the comments for a certain item
a link to edit the comments that opens up a modeless box
save button in the modeless box
I have tried the
Page.ResolveUrl(
And response redirect but they give me errors of unknown url) i am guessing it has something to do with the dynamic data crap.

I want to know how to respond to a request made by a mobile application (preferably Android) through a desktop software. So for example if there is a button on the mobile app named 'do something and a user clicks it, I want the desktop software to respond to that request and 'do something
So what I was thinking was to upload a file to a server when the button on the app is clicked and add a timer to the desktop software to connect to the server and read the file and respond accordingly.
Is this how it is usually done or am I going about this the wrong way? Im developing the app in C# (Xamarin) and the desktop software in C# as well.

I am trying to create "dummy" drivers for testing purposes of another program of mine.
I want to be able to Call DeviceIoControl and pass a string in as the buffer and then receive that string in the driver, change it and return it. But right now I am not able to receive the string, when i get the buffer and print it out it is garbage. Where am I going wrong?
TEST
int _tmain(int argc, _TCHAR* argv[]) {
BOOL freeResult, runTimeLinkSuccess = FALSE;
HANDLE RTC_IOControlHandle = NULL;
HINSTANCE FRS_IOControlHandle = NULL;
RTC_IOControlHandle = CreateFile(L"\.ROOT#SAMPLE#0000#{db3d5a0e-63aa-4b97-9d05-b50d5093a20f}",
FILE_SHARE_READ | FILE_SHARE_WRITE,

I have problems relating the HTTP server request line validation into a c++ code, where the request line is defined as follows:
method SP request-target SP HTTP-version CRLF
and the server supports absolute-path [ "?" query ]
At the same time absolute-path must start with / and might optionally be followed by a ? followed by a query, which may not contain ".
Basically, method must be GET, request-line must begin with / , request-target cannot contain " ,HTTP version must be 1.1 (HTTP/1.1), and the absolute-path must contain the character .

I need to write an interface program in C++ to receive occasional data being sent to me from a different company from across the internet. The company says they will send the data using POST. They have given me a document that lists their data specific parameters and their meaning.
How do I receive this data in my C++ program?

I want to write a little c++ program that sends a request to a server an get some data. I found the C++ Rest-SDK and decided to use it. I searched on different websites for code-examples but many of them doesn't work an shows syntax errors. What i got now is that code but the client.request method is skipped. The program never jumps in.
#include <Windows.h>
#include <iostream>
#include <sstream>
#include <string>
#include "cpprest/containerstream.h"
#include "cpprest/filestream.h"

I need to create C++ app that uploads a file using http request. I have the following php file on my server:
<?php
$uploaddir = '/var/www/uploaded/';
$uploadfile = $uploaddir . basename($_FILES['file']['name']);
echo '<pre>';
if (move_uploaded_file($_FILES['file']['tmp_name'], $uploadfile)) {
[Code] .....
Now, i know the general idea of how its supposed to be done but I just cant get it right. Either my "post" message is wrong all the time or some library is not working properly. Im not even including the code for the application because I have 5 projects, each with different approach and none of them is working.

Ok, so the assignment is to use a recursive function to display a request for a certain position in the Fibonacci Sequence (0, 1, 1, 2, 3, 5, 8, 13...)
The program I have written works, but it displays the wrong number in sequence. The book says that when you enter "8" you should receive "13", which is correct in the order of the sequence, though my program is producing "21" which is the next number in the sequence.
I tested it with a few more numbers and when I enter "7" it produces "13" and when I enter "6" it produces "8" and so on.
Code:
//Cameron Taylor
#include <stdio.h>
int main(){

Is there anyway to make when browser request some file from server than browser to load another file. Example:
I open [URL] ....
So now the browser send http request to load image [URL] ....
so when browser want to load that image to load this image [URL] ....

I have a question similar to the one here: [URL] .....
The main difference is I would like to pass a method of derived class as a parameter to some other method in its template base class.
template <typename BaseType>
class Base {
public:
typedef void (Base::*Callback)(int A);
[Code] .....
The above is an example which does not compile. My compiler complains that the two BaseMethod() calls in DerivedMethod() are invalid uses of non-static member function.
Is this not possible to do, or is my syntax simply wrong? All I want is to be able to pass as an an argument to a method in the base class from the derived class some callback as a variable for the base class to invoke later.

I am trying to develop a function which prints a binary tree using post-order traversal (left, right, root) but I am experiencing some troubles. The code is compiled but when I run the program it crashes right before printing the post-order traversal.
Below you can find my code and the output from debugging.
Code:
/**
Program which represents a Binary Search Tree and is modified with the following functions:
- smallest() - member function which searches for the smallest element in the tree.
- preorder() - member function which prints the tree nodes using pre-order traversal
- postorder() - member function which prints the tree nodes using post-order traversal (to be completed)

#include <iostream>
#include <cstdlib>
#include <string>
using namespace std;
class TreeNode {
