I am currently coding a 2D game in Visual Studio 2013. All of the .png graphics are saved in an absolute directory (for example, "C:/gfx/example.png"). Although this works for testing the application on my own system, I would one day like to release it (although it won't be commercial, as I am just learning). I could put all the of the image files in a relative folder, but I do not like the idea of my graphics being out in the open like that.
Is it possible to compile these images into the application itself? I had been researching resource files on Google, but I am still not completely sure if this is what I need to be using. Even if it is, I am using the express version of VS, so I do not have access to the editor. If resource files are what I am looking for, do I have to purchase an upgraded version of Visual Studio, or can I use another editor?

I managed to read txt files and printing them on the console window. I was given a task to select and sample a certain amount of data.
Example of txt file:
Voltage (V),Current (I),Power (W)
50,2,100,
51,2,102,
52,2,104,
etc.. How can I display only the column of Voltage and Power?

I have a std::vector<int> and I want to modify subset of the elements. I thought I might be able to use:
std::vector<int> a = { 1,2,3,4,5,6,7,8,9 };
std::vector<int> b(&a[3],&a[7]);
for(auto& each : b) {
each++;
}
for(auto& each : a) {
std::cout << each << "
";
}
but that didn't work. The elements of 'a' retain their original values. Then, I thought, "Ooo, maybe I could make 'b' a reference." Nope. What approach would be to access a subset of a vector for potential alteration?

I need to extract comments from a C file, which are usually marked with " /* This is a comment */ ". It seems to me that I need to calculate first at what position is the / and then ask it if on the very next position to the / operand is the *, if it is then I need check where is the next * and if / operand is immediately next to it. At last I need to take everything between values that the first and second * have. But I don't know how to write that in code.
This was supposed to be done in c++.

Suppose I have read a line from an ASCII file with fgets(). Now I want to parse the line, which looks something like this: Code: # John Q. Public et al. 2014, to be submitted The name, "John Q. Public" is what I want. However, the name can be anything, consisting of 1 or more tokens separated by spaces. it could be "John" Or "John Public", or "Thurston Howell the 3rd", or etc... Bascially, I need to get the entire substring between the first hash mark, and the "et al" in the line. I tried this: Code: sscanf(line,"# %s et al.",name); But I can only get the first token (which, in this case, is "John").

I have a stored procedure, which I cannot change (it is used by older programs). It is passed an int of 15 and then an ID is generated and written to a database table. The created ID is then suppose to be selected and returned.
The INSERT does not seem to be working. I'm not getting the created ID value from my code, I am getting the value I passed to the procedure when I get to this
line of code "sessionID = sessionProcedureID.Value.ToString()";.
Below the stored procedure and my code.
/***************Stored Procedure***********************/
USE [testDataBase]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON

ALTER PROCEDURE [dbo].[MakeValue]

I need to develop a simple program, i have 2 variables (begin, end), and i need to search in a file, And extract the string between the Begin and the End variables to a new File, For Example:
my text file: file.txt:
some text here<StartHere>more text here</EndHere>text text
C++ Program:
//Declear 2 variables
strcpy_s(begin, string("<StartHere>").c_str());
strcpy_s(end, string("</EndHere>").c_str());
//And now, search in the Text file, And Extract the text between the begin string and the End string.
<...>
The Result should be: NewFile.txt with the content:
<StartHere>more text here</EndHere>
That's it!, Here is what i have for now:
#include "stdafx.h"
#include <iostream>
#include <fstream>
#include <vector>
using namespace std;
int main() {
int ocurrences_count = 0;
int ocurrences2_count = 0;
char word[20]; //this array will save user input
[Code] ....

I have an array matrix called tmat,,and i know that in every row of tmax there are values which repeat two times...and am writing a code to extract the values WHICH DOES NOT REPEAT into another matrix called tcopy...the codes compiles fine...and it writes nicely to file...but without the desired result...
One last question...how can i get the array tcopy written to file in the form 5x3...and not all the figures in line one after the other? i mean i wish to see the matrix like a matrix on file..not like a list of numbers....
Code:
#include <iostream>
#include <fstream>
#include <vector>
using namespace std;
const int R = 5;
const int C = 5;

I have an embedded microcontroller system communicating with a similar system by radio. The api for the radio requires data to be transmitted as an unsigned char array. It will always transmit a positive integer in the range 0 to 255.When I receive the data I am having difficult in extracting this positive integer.
Code:
unsigned char rxData[4]={'1','2','3',''};
int inVal=0;
//want to assign inVal whatever number was transmitted
E.g. 123
I've been at this for a week and have tried at least 10 different approaches including the use of the atoi(), copying the absolute value of each element of rxData into another char array, reinterpret_cast, and others.

I am a beginner and I ALWAYS have the toughest time doing I/O files. It's extremely frustrating. It "seems" it should be so simple. The program should find a code from a list of numbers. These numbers are from 0 - 9, and after each number is a space in the file. Your job is to extract a special code containing only 10 of those numbers. For the number to be part of the code, it should be divisible by 2. After extracting 10 numbers divisible by 2 for the code, write those 10 numbers to the file to form the expected code.
Input file is ("question.txt")
Output should be ("code.txt")
Should this contain a "for loop" or If/else ?
Here's what I did . .
/
// int numbers, total, counter;
ifstream inFile;
inFile.open ("question.txt");
outFile.open ("code.txt");
if (!inFile)

How to write a C or C++ program that extracts certain numbers out of a section after the 4, 5 and 6 space.
For Example:
The output file will produce:
[ [1900 00 0 -2.000000 0.650000 0.006000 0.020000 2.274000 0.010000 54 0 0.7 10.8 1 0 0 0.000000 17.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 18];...
So I want to extract the numbers 0.650000, 0.006000, 0.020000 because those are the 4,5,6 space after [ [
Another problem I have is that the output file I showed will always being updated constantly for instance as follow:
[ [1900 00 0 -2.000000 0.650000 0.006000 0.020000 2.2054000 0.010000 10 0 0.7 10.8 1 0 0 0.000000 17.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 13];...
[ [1900 00 0 -1.000000 0.650000 0.006000 0.020000 2.694000 0.010000 9 0 0.7 10.8 1 0 0 0.000000 17.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 10];...
[ [1900 00 0 -2.000000 0.6023000 0.04000 0.050000 2.2454000 0.010000 5 0 0.7 10.8 1 0 0 0.000000 17.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 12];...
And it will keep updating like this and I want to update the previous numbers I extracted with now the new numbers after the 4,5, and 6 space.
So I have to write a code to let it know when it encounters [ [ start looking for the 4,5,6 space and get those numbers and once it reaches ;... that's the end of that section so re-look for the next section of numbers after the 4,5,6 space.
The file will be a text file or matlab file that is always being updated with these sections of numbers. Can I make this a #include<nameoffile.h> or does .h not work with a file that is always being updated.

I am trying to extract unsigned values from an input stream. I expect the extraction to fail when an invalid character is extracted. It fails correctly when I try to extract an unsigned int from "abc", but when I try to extract an unsigned in from "-1", the extraction succeeds, and the max unsigned int value is extracted (as if -1 were cast to unsigned int). I would expect the '-' to cause the extraction of an unsigned value to fail.
The code I am using is below.
#include <iostream>
#include <sstream>
#include <string>
#include <limits>
int main() {
unsigned int value = 8;
std::string negString = "-1";
[Code]...
Is this standard behavior for an istream extractor?
I am trying this in both Linux (gcc 4.4.3) and in windows with Code::Blocks (whaterver came with CB 13.12, apparently gcc 4.7.1)

I need to write a C++ program, that extracts certain variables, x y z, from a file that is continuously being updated x y z. These variables are going to be used to recalculate a new answer.
My question is to see if it is possible to have an include .h file that is always being updated so that I can extract these three variables from it, and always have the newest venison of each variable, so that the answer to the equation is always the newest updated. Should I use fopen or fwrite to do this.

I need to know about image processing whether it can be done using C /c++ as I am not familiar with MATLAB. I have attached one image. The arrow in the image show the indented circular portion. I need to crop out only the portion inside the indented portion. I think there should be a sharp difference in gradient intensity in pixel at the indented portion. Is it possible to extract that portion out by reading the binary image?
