I'm trying to make a basic settings text file and I'm wondering why pos_y = strAxisData.find(",", pos_x, strAxisData.length()); returns std::string::npos when pos_y = strAxisData.find(","); works fine ? The settings text file format is:
string strAxisData;
while(finConfig)
{
getline(finConfig, strAxisData);
pos_x = strAxisData.find("=");
if(pos_x != std::string::npos)

My current idea of how to work with user settings goes like this:
1. Create a class to hold all of the user settings.
2. Use that class to load/save/hold settings in memory.
3. Create an instance of that class once in the entry point of the program (int Main or whatever).
4. Pass, by reference this same class instance around to all of the other classes that need the user settings.
5. Once all other objects deleted, save and then delete the User Settings class.
I created a psuedo-code example below of this. My question is if this is the best way or should I be doing something else. In particular, I am wondering if somehow I can avoid passing the settings class by reference all of the time. Would this be a good case scenario for a "Singleton" type class?
#include <string>
class UserSettings {

std::string SettingOne;

I want to configure netbeans 7.4 settings for c++.I'm posting here because netbeans forums are close to dead. How to do the following things :-
1) When you create a new project of a 'new application' type, main.cpp is already there with some code. I want that main.cpp to be completely empty when I create a new project.
2) When you compile/build your program and run it, the output is shown in a small log window at the bottom. I want it to be shown like in a black output terminal (console ?) just like in Visual Studio or CodeBlocks. (I have some reasons for not using them instead, so don't bother about me not using them)
3) When you click the green 'Run' icon in the upper toolbar, the project is compiled/build again and then runs afterwards. I want it to just run without compiling. (Compiling/Building should be done by 'Build' icon, just like in CodeBlocks or Visual Studio)

View 3 Replies View RelatedI've created a solution who exported Access reports (graphics/tables) to a Word- and a PDF-format. Therefor I use PDFSharp and PDFFocus.
The PDF document is okay. But the Word-document looks good. Only the size of the Word-document, it has to send by e-mail, is much too big (17MB).
I have to open the Word document again to change the PageSettings to be sure, that the page-margins and the print orientation are correct.

I don't know how it works in the Word-library source. But I've tried WdOrientation.wdOrientPortrait and once I was surprised. I saw this page in Landscape-format.
I think there is something wrong with my document sections, because the documents (with a lot of tables, graphics and a image) is much too big. And that's only after using this method.
So my next question is: How can I shrink the size of this Word document?
And what do I have to do to limit the amount of format-settings in this word-document?
Program background: Ticket Sales Details You will sell tickets in advance and at the door. Prices for buying in advance and at the door will be given. Also, the total number of tickets sold in advance will be given. Each guest will have a unique number. If there are n tickets sold in advance, then these guests will be numbered 0 through n-1. As the event starts, requests to buy tickets at the door may be made and these guests will be numbered sequentially, starting at the lowest unassigned number. The maximum number of guests will be 1000. The first line of the file contains the following three values, separated by spaces: Cost of the presales tickets (in dollars), Cost of the tickets at the door (in dollars), and the number of presale tickets. The first two values will be positive real numbers to two decimal places and the last will be a positive integer.
The second line of the file will contain one positive integer representing the number of auction items followed by a positive real value to two decimal places (at most) representing the minimum bid increment, in dollars. The first value is guaranteed to be 1000 or less and the second will be in between 1 and 50, inclusive.
The third line of the file will contain all the prices of the auction items, in dollars, separated by spaces, in order. Thus, the first price is the price of item 0, the next price is the price of item 1, and so on. These values will be real numbers represented to up to 2 decimal places.
The fourth line of the file will contain the three following positive integers pertaining to the raffle: the number of raffle tickets available, the cost of a raffle ticket in dollars, and the number of raffle prizes. (It's strange to have raffle tickets that don't cost a whole number of dollars.)
The fifth line of the file will contain each of the values of the raffle items, in dollars, separated by spaces, in order. Thus, the first price is the price if item 0, the next price is the price of item 1, and so on. These values will be real numbers with upto 2 decimal places.
The sixth line of the file will contain ten positive integers representing the number of each of the drinks 0 through 9, in order, that are in stock.
The seventh line of the file will contain ten positive real numbers with upto 2 decimal places representing the price of each of the drinks 0 through 9, in order.
The eighth line of the file will contain a single positive integer, numEvents, representing the number of events that occur at the charity ball. These events are split into two groups: actions by guests at the ball and awards given (raffle, auction, person, totalrevenue). All of the actions precede all of the awards. You will produce exactly one line of output for each event described. Here are the formats of each event that could occur:
If a patron buys a ticket at the door, a command will be on a line by itself:
BUY TICKET k
where k is a positive integer indicating the number of tickets bought at the door. These guests will be numbered as previously mentioned. You are guaranteed that the total number of tickets bought, including presales, will not exceed 1000. This is what I have so far and I cannot figure out why it wont calculate the total revenue. I am not completely sure if it is even accessing the if statement in main.
Code:
#include <stdio.h> #include <stdlib.h>
#include <string.h>

I am trying to write a program that will open a file with 2 points, take those points, determine what quadrant those points are in, and save the result back into the same file without truncating the data.
I'm having some trouble with my file I/O. I can't get my program to read the two values for X and Y that I put in the points.txt file. It simply uses whatever random number was used last time in that block of memory. In my points.txt file I put something like "4 -5" and it wont assign those numbers to my X and Y variables. I believe the issue is on line 25

I am practicing with C++ since I done most of C already and I have a problem with reading spaces from a .txt file.
I created a little program that creates a wannabe Cube in wannabe 3D xd, well to appear as 3D like:
Code:
cout << " O------O" << endl;
cout << " / /|" << endl;
cout << " / / |" << endl;
cout << " / / |" << endl;
[Code] .....
The actual code is a bit longer since it offers you to input the size and then it draws the pic. Now that wasn't so hard and I've done that but now I wanted to implement the "MessageBox" func for output.
I managed to write the cube in file cube.txt but when I'm reading from it 1 char at a time since I need to output as char array it avoids all spaces and new lines and just puts all symbols in the same row.
I didn't have that issue with C and I've found on stackoverlow a solution using strings & getline but I need it to be in "char" form.
How to actually read spaces and newlines? This is my current code for reading from file:
Code:
ifstream di("kocka.txt", ios_base::in);
char c[5000];
int br=0;
while( di >> c[br])
{
br++;
}
MessageBox(NULL, c, "Kocka", MB_ICONHAND);

I'm writing a program using Huffman algorithm to compress text file. I have tested my program by just printing the printing ASCII character to file and it worked fine.

Basically I want to open a binary file containing utf-8 encoded characers. The length of the encoding is variable: 1, 2 or 3 bytes.
Rules are:
if the read byte has 0 as strong bit then it represents a single byte.
if the read byte has 11 as strong bits then it represents the first byte of a 2 or 3 length character.
if the read byte has 10 as strong bits then it represents the second or third byte of a 2 or 3 length character.
Each character encoded on 2 or 3 byte has to start with a 11xxxxxx and following bytes has to start with 10xxxxxx
So i need to go through his file, read byte per byte to analyse what kind of byte it is, sometimes go back to previous character etc etc
My goal is to identify all encoded characters in the file and then process them by convering them to Unicode value, storage in array etc...
So im just trying to read in an pgm file and store it in an array,
Code:
int** imageArray;
//allocate the image array
imageArray = (int**) malloc(row * sizeof(int*));
for(i = 0; i < row; i++)
imageArray[i] = (int*) malloc(col * sizeof(int));
[Code]....
It stores about 1/3 of the file into the array, and then starts printing 6815940 6819608 followed by a bunch of 0's.
It appears that when you enter command line arguments or use fgets() to input a string you can assign that string to another string variable using the assignment operator. But when you read from a file, you can't do that, you get a segfault. It seems the only way to get around that is to malloc the string and use the strcpy function.
Code:
#include <stdio.h>
struct person {
char *names[2];
};
void readFile(struct person p){
FILE *file = fopen("names", "r");

Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <conio.h>
