I am trying to read this xml file. This readFile function does not give me right values. Only to use cstring..no pointers or other libs such as xml libs
void readFile(char file[], ifstream& read){
char line[chr_len];
read.open(file, ios::in);
if(read.fail())
cout<<"Sorry could not read";
[Code] ....
Also how can i only read the values..not the tags?
I am writing a program which compresses files into .zip files.
Here's my problem: Whenever I want to compress an executable file, my readFile function does not read the entire file. When I extract the .exe I get a very tiny and incomplete file.
Here's the function I use to read files:
std::string miniz_wrapper::readFile(FILE* f, int MAX_FILEBUFFER)
//MAX_FILEBUFFER has a default value of 65536 {
char* tmp;
std::string tmp_s;
int count = 0;
[Code] .....
Prior to reading, every file is opened using fopen with the mode "rb".
I cant get with part of it is wrong, i want to sum every row, too.
// Color Number.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include<conio.h>
#include<iostream>

I have a problem with ReadFile and overlapped.
first I use ReadFile with overlapped with 0
Code:
ZeroMemory(&overlapped ,sizeof(OVERLAPPED));
hDevice = CreateFileW(zwpath, GENERIC_READ | GENERIC_WRITE, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL | FILE_FLAG_OVERLAPPED, NULL);
if(hDevice != INVALID_HANDLE_VALUE){

I'm creating a bank system.
So I know to make a deposit to the balance, which add ups what is the balance to i have add.
When i run the deposit function, its work well in some ways. If balance(text file) has the value 10, add i addSum 20, the balance will become 30, same as the text file will become 30. so its work well to add positive number.
Code:
double deposit(double balance) {
double addSum = 0;
system("CLS");
cout<< "Welcome to deposit."<<endl;
cout<<"Enter a sum you wish to add to your account:";
[code]...
When I withdraw from 30 which is the balance, then i takeSum, for example i take away 30. The balance will become 30 - 30 = 0 When i make another withdraw from example -150, it will be -150.Which shows correct.
But when i make a deposit from -150 and i addSum 130, the balance shows -500, and it should had been -20.
Code:
double withdraw(double balance) {
double takeSum = 0;
system("CLS");
cout<< "Welcome to withdraw."<<endl;
cout<<"Enter a sum you wish to take away from your account:";

I am trying to read the file which has the values stored in the following pattern
2 4 10 103 2 504 .... and so on
I Have opened the file and then passed the opened file to another function to process it further.
here is my code
#include <iostream>
#include <fstream>
#include <vector>
#include <stdlib.h>
[Code].....
now the problem is when the control exits the "while loop" in the function "readingValues(std::ifstream& myFile)it goes straight to catch block ?
I was told to use a round function to round a number to give an integer number that is closer to the real value. (for example if the number is 114.67 I need to print an int value of 115 instead of 114)
I am not exactly sure how a round function works, but I am told to include math.h library. What I try doesn't seem to work.
I'm trying to pass 2 arrays into a void funtion, and return values to one function.
this is the the program I'm working with, after I'm done I have to split it into 3 files, a header, a main, and a separate cpp file for the functions to live in.
#include <iostream>
using namespace std;
void processArrary(int numberCount[], int Numbers[], int intnumberSize, int numberCountSize);
int main() {
int Scores[26] = {76, 89, 150, 135, 200, 76, 12, 100, 150, 28, 178, 189, 167, 200, 175, 150, 87, 99, 129, 149, 176, 200, 87, 35, 157, 189};
int numberCount[8] = { 0 };
[code]...
The goal of this program is to separate and count the groups of numbers then output the amount of numbers in each group. Near as I can tell, everthing should work, but I'm getting all zeros to be displayed in each group.
The function is supposed to return value from the file in my main, but I am getting empty value. I am trying to get better with pointer. Right now just teaching myself.
right now the only way for this code to show value is when in put the putchar(*ps) inside my readfile function. I would like to readfile to return value and print in the main function.
Code:
#include <stdio.h>
char *readfile(char filename[]);
int main(int argc, char *argv[] ) {

Is there any methods to add scroll bar for group box
My code scenerio is: I have many groupbox in form, all group box will be appears in same place and also height and width is fixed. I'm doing group box visible true/false according to condition.
So some groupbox ecxeeds the width and heighto so I want to put this all in scroll Bar
I'm trying to build a basic shell for Unix. This is the code I use to create a new process:
Code:
pid = fork();
if (pid == 0) {
setpgrp();
complexCommand(argv, isComplex);
[code] .....
Where complexCommand is a function that handles the command (uses execvp after generating the correct string out of argv). My problem is that after if while in the shell I use a program that needs to print to the screen and handle input, it doesn't work as expected. To test this, I built this small program:
Code:
#include <iostream>
#include <stdio.h>
#include <stdlib.h>
using namespace std;
int main() {
int x1, x2;
[code] ....
And when I use the shell I built to run it, the output is only "Enter 2 numbers" for one time. It doesn't print the result, or anything else. Is there anything I need to do in the parent process (my shell in this case) to give the child the output?

I need to write a program that will give me multiple calculation results.
#include <iostream>
using namespace std;
int main () {
int x = 8;
int y = 7;
[Code] ....
It only calculates the last two numbers: 1 and 0, so therefor it gives me 1.
But i need to calculate x and y each time they are smaller(incremented) by one digit.
Please note that the int calculation formula needs to stay.
i have only recently got into programming. i have this homework assignment that is frying my brains, the program needs to take a number from the user and give the 'reduced' sum. for example: if the user enters 888 then the sum should be: 6. it takes the number and adds its digits im just looking for a direction to where my problem is
#include "iostream.h"

return number/10+number%10;

how to give error and ask user to re enter if user enter other then a number?
I am in the process of writing a program that will give the appropriate color code for a resistor after the user enters an integer value for the resistance needed and selects the tolerance form a list. My question is this: Is there a way to allow the user to enter a value such as 75000 and C++ use each digit separately, as if they entered 7 [enter], 5[enter], 0 [eneter]... and so on? But, then use the entire value as an integer too? Also, it should read a value such as: 45835, as 45000, or 1843 as 1800.
