I am trying to open a file and print the contents of the file to the terminal window. It works when I put the file right in the directory with the Solution but not if the file is out on my desktop and I use the full path. Here is the code:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int OpenFile(){
fstream SampleFile;

I want to:
1. Load HTML File (or take stuff from string)
2. display window with content of that html
so yeah, basically something like a browser, is there some lib that will just load html and do it for me? I dont need whole browser, I just need to show really simple html pages in my app....
How it make it work for my project. Runtime means I am going to have to give the path at the command line?
Here is how I have to run it, so I can test it against the example inputs and outputs they give us to test our program. I am using putty. Already crated the folders inside my project folder, but don't know how to implement it on my source code.
./movie_stats < ./input/test1.in ./my-output/test1.out
What I'm thinking is to open/create the file test1.out in the my-output folder and open it at runtime?
I have a folder "pics" in g: drive. There I want to create some text.txt file. Thus, the final path is "g:pics ext.txt".
How can I do that?
I am trying to store a large text file into an array so I can count the number of characters.

The only Problem I have is that I need to know how to open a command window at the folder containing the .exe file(this program), inorder to enter the program name or arguments.
I am using
string text = System.IO.File.ReadAllText(@"C:datainput.txt");
to open a file and save it content to "text"
How can I instead create new window where user will select the .txt file he wants to read like many applications do
This is a WPF application
Taking a OS course and my professor gave us files to reference in a directory located at ~agw/class/os/share/proj3. But when I typed this into the terminal I keep getting a permission denied error message.

I'm not sure what I am doing wrong. Ive opened shared directories for this class before and had no issues.

I've created a text file with the numbers from 1-450. After writing code to retrieve and print out the contents in the text file, the compiler only printed out the numbers 124-450. Is there a reason why this is happening?

I have written the following code but i am stuck. Write a program that will prompt the user for a file name and open that file for reading. Print out all the information in the file, numbering each new line of text.

Suppose I have a txt file that I want the contents printed to the console in such a way that every five words are colored blue and the following five are red. How do I accomplish such a task? I am currently only able to print the contents of the file in regular color using ifstream.

We are required to open a text file, read the data from that file, and print it back.
However, we are supposed to let the user input the name of the file that is to be opened. This is the code I have so far. It is not opening anything.
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
const int NUM_QUESTIONS = 30;
typedef char CharArray[NUM_QUESTIONS];

There is only one thing I need here. When the paint program is opened I need it to automatically open it maximized. Other than that my code works perfectly for what I'm trying to build.
It has to be maximized so when a friend opens it after I send it to him, it auto maximizes and doesn't start drawing on his desktop.

Is there a way to change what a relative path is referencing after runtime has started?
My specific issue is that I have several existing 100,000+ LOC lua projects. I am building a new back-end in C/C++ for this by wrapping a Lua C library. The lua scripts use io.open("./path/relative/to/project/file") which translates to fopen(...) in C. The project file which this is relative to is opened by the user after the application has started.
I see two solutions, neither are particularly good:
1) Change every io.open() function in every project to be relative to a static location. I lose all flexibility if I do this.
2) Modify the Lua library to prepend a custom path to opened files. Modifying 3rd party libraries suck because you can't update the library without tracking patches.
3?) Ask cplusplus forum if there is a way to change the relative directory.
My program accepts strings, places them in a vector and then "bleeps!" out words of my choosing, in this case, "broccoli". But I'm having trouble keeping the output window open even with my Keep_window_open() implementation.

I have a list with 2 items in it. When I double click on item 1, I want to open Window1.xaml, when I double click on item 2, I want to open Window2.xaml...
The code below works for popping up a message box, or window for that matter. But I really need to get the Window1 and Window2 based on the clicking of the correct selected item in the list.
Here is some code:

I am developing an app that shows a pixelated picture in a window. I am trying to capture the image, which is composed of a number of tiles processed from a mother image, but I am having difficulty since I can't reference the image on the screen. I have placed a rectangle around the image and my understanding is that I have get the window handle for the rectangle in order to save the Image as a jpg file. In the literature there is something about a Device Context and a window handle but my compiler throws out HWND and I don't really understand the device context. I am using Windows Forms, not native code.

The problem is that when I want to use pagination (with A4 pages), the printed text (which is just 4 sample line with 40 chars at most) at the code lTextPrinted =FormatRange(&fr,TRUE); is always lesser than the actual text pointed by the lTextLength variable making the loop run for ever. notice that using the RichEditControl Version 1 it works fine.

I need to create an overloaded cout that will print the contents of an array. So I can say output << a << endl;
And it will print the contents of the object a... which happens to be an array.

List();
bool empty(); //returns true of false if empty
void front(); //makes current position at beginning of list
void end(); //makes current position at the end of list

I understand this code, I am simply calling the size method from the program, but i don't know how to pass in the array so that i can print it line by line... simple syntax i am sure... but the whole thing is baffling me... I need to be able to call this on any variation of the class, so it cannot be specific to any one array.

I am trying use a print function to print out data in a struct. My questions are:
1. I have to use pass by reference. For the print function, I am passing the struct pointer as a reference, however, I don't want the print function to accidentally change anything. How can I make it use const to ensure that?
2. The deleteprt function doesn't look right to me. I feel like it should just be delete ptr not delete [] ptr.
