C++ :: Server Request Line Validation?
Oct 30, 2014
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 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"

According to my project instructions, I have to make a "validation on the delete button, that before a record can be deleted it will check to see if the count of "In-Progress" orders for that product is 0. If it is greater than zero, it should not allow this record to be deleted."
So far I have on the code behind page:
protected void btnDeleteProduct_Click(object sender, EventArgs e)
{
DataView dv = (DataView)SqlOrders.Select(DataSourceSelectArguments.Empty);
[Coe].....
The professor said I have to: "As for getting the count, check your notes and book, specifically looking at SQL and the Aggregate functions. There is a function we talked about in class called "Count(OrderID)" and set the where clause to check for the productID.

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 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 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(){

How do you do the input validation for date? I used:
char rec.date[SIZE];
cout<<"date"<<endl;
cin.getline(date,SIZE);
I want the user to write in this format (mm/dd/yy)

I am having a problem with my "void Validation :: getId()" function its suppose to get the id number from the user but when I try and type a letter to see if it catches it, it goes into this continuous loop. Also with my "string Validation :: getName(string name)" function it suppose to catch the comma in the user input for their last name , first name but doesn't catch it and still returns the name back to main function.
#include "InputValidation.h"
#include <iostream>
using namespace std;
Validation :: Validation() {
name = " ";
id = 0;

I'm writing a program to check whether codes from a file are invalid, valid, inactive, or valid and active, but can't get it to work properly. The invalid codes are being found, but the other three are not. I think it may have something to do with my "active" function.
#include <iostream>
#include <fstream>
#include <string>
#include <cctype>
using namespace std;
struct ActiveCodes {
string code;
bool flag;

I have this function that is supposed to take a float as a parameter and then call the getLine() method to accept the users input. The function basically just checks to see if what the user input was of the same data type, if it is it returns the input value, if not then it keeps looping through taking new input until its correct. The problem is no matter what number you put in the output always returns as 140734799803512.
float InputValidation(){
float num;
string strInput;
while (true){
getline(cin, strInput);
[Code] ....
You also need to include <string> and <sstream>.

My issue is regardless of which date I input its always defaulting to the values I have set in my constructor in my implementation file in the else statement. So the values always default to 3/15/2006 I think its something to do with the logic in my bool function but I may be incorrect.
header
//date.h header
#include <iostream>
#include <string>
using namespace std;
enum DateFormat {numeric, standard, alternative};
const int MIN_YEAR = 1900;
const int MAX_YEAR = 2015;

How I could correctly validate user input when the user inputs a numeric value that will be float pay1, pay2, pay3, pay4. However, the if statement that I wrote crashes after I test the validation. I been told that scanf is dangerous, but strtol works best, but how to write a validation with strtol.
#define _CRT_SECURE_NO_WARNINGS
#include <stdio.h>
#include <string.h>
#include <conio.h>
#define ARRAYSIZE 2
#define FORMAT "First Name Pago1 Pago2 Pago3 Pago4 Total Net"

I'm trying to make a function that verifies if the char entered is consonant, if not, prompts user to enter another char and when it meets the criteria, return the char. I was able to do this using switch statements (which works, and i'll paste it below) but I wanted to know if there was an easier, perhaps more elegant solution for accomplishing this goal.
char isCons () // data validation for consonants{
char userCons;
bool notCons = false;
cout << "Please enter a consonant: ";
cin >> userCons;

So I am writing a multiform multiclass project for a class and I initially set out to create a validate class to check all of my text boxes. However after writing a few simple boolean functions to check if the box was empty or not, or if it was indeed an integer, decimal ect. I realized I was going to have to call these functions for every text box and also have all of my decision making based on the returned boolean variable still in the code portion of my form. I was wondering how do most people do it, should I write a class that validates the entire form at once(one form has 7 text boxes, one has 9). I suppose I am asking what would the industry standard be, how would a professional do it? While my simple functions would work, and while I could write one large function that validates them all at once both paths leave something to be desired in terms of re-usability for the entire form validation, and compact/cleanliness of code for the simple functions.
My validate class currently stands like this:
class Validate {
bool isValid = true;
int trash;
bool valid_string(string input) //parameter is textbox.text property {
if (input == string.Empty)

So I am writing an assignment to Detect prime numbers and it works by Asking for how many values you are going to enter, and then saying "Enter value 1: "
Then you would input and it would calculate via for loop, and that part is working. However to make my program more foolproof, I devised a way for the user to be unable to "Break" the program by inputting characters or float values. Here is the code for that:
while(!(cin >> num)){ //num is some type (char, float, int etc.)
cout << "That is not at valid input, please try again" << endl; //"Error Message"
cin.clear();
cin.ignore(10000, '
'); //Clear and reset cin
cout << "Enter value " << n << ": "; //Re-Prompt User for input
//n is whatever value the for loop is on
}
and this code works fine, I was just curious about how i would turn it into a function. Preferably wiht the name: ValidateInput(Param1, Param2);
The Parameters of the function preferably would be the variable youre inputting and the message you want to prompt. So somehow i wish to have it so for the above example it would look like:
ValidateInput(num, "Enter Value " << n << ": ");
But I don't know exactly how to label either parameter part because I want it to work for chars, ints, floats etc. And I don't know what I want it to return if anything either.
