C# :: Saving Variables To Text File
Jan 26, 2015
I started with C# 2 days ago, but i have made 3 "games". Its something like Cookie Clicker, very simple and very easy.
But I have problem with saving the game. I want to save values of variables to text file when i click on button, and when i click on another button i want to values of variables load. Just simple save system. How it works and so.

I'm very new to c and c++ and am currently working on a Caesar cipher that grabs encrypted text from a txt file and decrypts it onto a new txt file. My code builds fine in CodeBlocks and when I run it, there is a new txt file created but it stays blank.
#include <iostream>
#include <fstream>
#include <string>
#include <stdlib.h>
#include <cstdlib>
using namespace std ;
int main(int argc, char *argv[]){

I have a program that saves all information temporarily into memory (into the array), however, I need a permanent save solution. I have the full program working correctly, formatted perfectly, but it's missing the file array to file output.
Essentially, whenever I'm presented with the menu I'll be able to add entries, search by last name, show the entire list, and exit and save. Whenever I select option 4 the program should save to a file "address_book.txt". Whenever I reload the program, it should load from "address_book.txt" and populate the array with the preexisting data.
My question is focused on how and where I should implement the file output. What I have thus far:
#include <iostream>
#include <string.h> //Required to use string compare
#include <fstream> //Eventually used to store array into file
using namespace std;
class AddBook{

Right now I'm working on an assignment where I need to take the data from on file encrypt it by adding 5 to each byte and then save it to a user specified location. I think I'm close to having it done but I've run into a hick up. After I get the user input for where the encrypted data should be saved the program seems to never end. This is the code I have so far
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main()
{
ifstream input;
ofstream output;

My project involves writing a c program to generate a set of 70 decimal numbers. I want to save the output (these 70 numbers) as a txt file. I tried the following:
1. prt scr of output screen and pasting it in notepad. NOT WORKING
2. going to DOS SHELL and doing the following:
c:TCBIN>output.exe>>output.txt
NOT WORKING. Text file is generated, but it does not contain output. It just says:
illegal command: output.exe
What do I do?

Why my code is not working?
Interface
class Person{
private:
char name[80];
short age;
public:
void get_data();
[Code] .....
This is a simple example from and old Lafore C++ book, with a few tweaks by me. The point is simple. Save object person to a *.dat file, exit the program, then start up program again, open up *.dat file, and load contents.
The first problem is the compiler is printing a bunch of Asian characters to the file (is this normal?)
The second problem is, it's not loading the object as it should, giving me a bunch of gibberish.

I have been working a while with saving and retrieve structs, and I still have not got it to work. I get Segmentation fault sh "${SHFILE} . I have search this error, and it has something to do with memory, but what, since I am a beginner with saving and retrieving files. The project runs fine, and the error stated above outputs into my console window as text.
Here are my two structs:
struct checkbook {
char id[50];
double value[50];
};
struct fbook {
[Code] ....
Here is how I save and retrieve my structs:
void saveCheckbook (string file, checkbook checkbook, double initial, int counter) {
string path = "C:UsersAshwinGoogle DriveC++Checkbook" + file;
fbook save;
save.counter = counter;
save.initial = initial;
save.book = checkbook;

I'm intrested in creating programs of games and such which learns while playing and saving the information for further use. For example a tic tac toe game where the program saves evry game it won or lost and creates a tree of some kind that store the information of the game and save it in a file when the program is being quit. The problem i'm having is how to save a tree in a file efficently.

I have written code that saves a matrix to a utf-8 file. This code works just fine when invoked from a win32 console app, but if I attempt to use the exact same code by invoking it within a SDI Doc/View Serialize(CArchive& ar), if(ar.IsStoring), it fails, but in a somewhat unusual manner. Namely, the file shows up in the designated directory, but it is an empty file (0 bytes), and the 'Unable to open file' message is seen in Debug config. Note that both the win32 console app and the SDI app are both using a Unicode character set, however, only the SDI app uses the method inside a Serialize(CArchive& ar) method, whereas the win32 console app evokes the save method directly from within _tmain. Why this seemingly illogical disparity occurs.
Here's the template code I have used in innumerable applications to save matrices to a disk file.
Code:
namespace TNT {
// saves a TNT double matrix, discriminating between real and complex matrices by virtue of the respective file markers, 'MATCALC94R' and 'MATCALC94C'.
template <class T>
void SaveRealBMatrix(const Matrix<T> &M, string sfilename) {
_RPT0(0, "SaveRealBMatrix:
");
_RPT1(0, "sfilename =: |%s|
[Code] ....
Here's the code from the SDI document Serialize(CArchive& ar) that fails as described above. Note that m_M is a class member TNT::Matrix<double> m_M that has been verified to exist in the Serialize method.
Code:
void CMyWndDoc::Serialize(CArchive& ar) {
if (ar.IsStoring()) {
CString csFileName = ar.m_strFileName;
wstring ws = csFileName.GetBuffer(0);
string s(ws.begin(), ws.end());

I am trying to find a quicker way of setting the variables for text. here is my code:
sf::Text set_text_values(sf::Text text, sf::Font font) {
text.setFont(font);
text.setCharacterSize(50);
text.setColor(sf::Color::White);
return text;
[Code] ....
And I have tried it like this
void set_text_values(sf::Text text, sf::Font font) {
text.setFont(font);
text.setCharacterSize(50);
text.setColor(sf::Color::White);
[Code] ....
The code compiles and runs but it won't show the text on the screen like it did when i did it manually like this:
int main() {
Hull.setFont(font);
Hull.setCharacterSize(50);
Hull.setColor(sf::Color::White);
}
What is wrong with it?

I am using fin.peek() to read character from input file and saving each character into an array. Each line from the input has first name, last name, id number, and then 5-6 grades. Random spacing between each one.
input file example:
Adam Zeller 45678 80 87 60 90 88 100
David Young 34521 34 56 76 76 76 76
Carl Wilson 909034 90 90 90 49 39
my code for reading in and storing each character is this:
while(fin.peek() == ' ')
fin.get();
while(fin.peek() != ' ') ///// first name {
c = fin.get();
first[i] = c;
[Code] ....
The problem I am having is what sort of loop would go around this to read till end of file. I have tried eof. I have tried while(!fin.peek == ') and I have tried a couple of other methods. these methods resulted in a never ending loop execution.

I am trying to establish a connection between client and server to send a file to the server from a client. I have been successfully able to send files to the server but i am facing a problem with the the filename whenever i try to send any string to the server and use it in naming the filename at the server side, the string is successfully concatenated but it saves the filecontents in the filename.
for example: i am sending a file hello1.txt to server and the server has to save it as abcxyz.txt as i am sending the "xyz" from the client. BUT Whenever i am doing this ,the file saves as abcxyzfilecontents.txt If i saved in the .txt file "you123" ,my file at server side would save as abcxyzyou123.txt
Here are my codes:
Know that the server code implements a multi threaded server. The functionality to be discussed is defined in myfunc
Code:
server.c:
#include <stdlib.h>
#include <stdio.h>

I am working on a project that uses a web service to extract a PNG image from a web server and save it on a local machine. It's done via a system call. I can get the output of the system call to a FILE but it appears to be losing data, most notably the PNG chunk names (IHDR/PLTE/IDAT/IEND, notably). (Unfortunately piping the output to an exterior file does not work through a system call.) The end result is ~6KB smaller than the file I am intending to retrieve.
This is the code I'm using (adapted from other material I found via searches here):
ofstream png;
png.open(/*outputfile*/, ios::binary);
FILE* fp = _popen(/*SYSTEMCALL*/, "rb");
string responseString;
if(fp != NULL) {
char a[100];
while(!feof(fp)) {
fgets(a, 100, fp);
responseString += a;
}
}
_pclose(fp);
png << responseString;
Am I missing something or just doing it wrong?
