C :: Make A File In Directory That Cannot Be Deleted By User Out Of Program
Jul 4, 2013
I have two questions about C programming here :
1. I want to make a file in the program directory that can't be deleted by user out of the program make that file.for example if I make a file named "123.xyz" by the program named "text.exe" and then exit test.exe ,if I tried to delete the file 123.xyz I faced the error and I could not do it but by the test.exe program that make that file.
2. I heard about a function called "Parbegin()".any way i want to know is there any possible way to run two or more functions of a file.c together,like the parbegin function did an do in OS?
So I'm trying to make a program that asks the user for a number and then prints a statement the same number of times the user entered. 3 different statements, using the 3 loops (for, while, and do while). I made the program but for some reason the statement from the do while loop goes off infinitely.
I need to write a program that acts as a file manager for all the files and folders in the directory given as an argv parameter and all of its subdirectories. This means be able to move, rename, delete the files in the sub directories. Also I need to be able to store the structure of folders and files in a binary tree adt (I have one already). But I'm not sure what libraries to use with this and how do I open a directory is it like a file with fopen?
I need to write a program to make the user input some text, and the first letter of each word has to be uppercase. (have to use while loops)
So for example lets say the user inputs:
i lOvE pRoGrAmMiNg
The output needs to be:
I Love Programming
Code: int main() { char c, lower_c; printf("Enter Text"); while (c != '' && c >= 0) { if (c >= 'A' && c <= 'Z') lower_c = c + 32; else lower_c = c;
[Code]...
I have started this code by making the letters lowercase (I don't know if this was the right way to approach this, ). I am not sure how proceed after this step, the step of making the first letter uppercase. (PS for the program, loops should be while loops)
I have my Reverse Polish calculator compiling and everything but for the assignment I need to handle a few exceptions that I can't seem to get. First off I'm trying to make the program exit if the user enters only "0" but since the input i'm using is string, I cant figure out how to code
"If the first node is 0 and the next node = NULL, return true"
Here is my code: #include<iomanip> #include<iostream> #include<stdlib.h> #include<stdio.h> #include<string> #include<sstream> using namespace std;
I want to obtain the user's home directory. I know it can be done with getenv("HOME"), but if I'll inspect the value of the enviroment variable HOME, it might work when I run it now, but it won't work on Windows, since windows uses HOMEPATH to save the user's home directory.
Is there a different, more cross-platform way to do it?
I have a logined user and my running program as system process (not user process).
I want to get user name and surname from AD.
1. GetUserName() dont useful becouse it gets name for current process owner(for SYSTEM in my case).
2. There are userLogin, userName, userSurname and userDisplayedName in user properties of AD. Its possible to get userDisplayedName by NetUserGetInfo(), but I want to know is it possible to get userName and userSurname?
I have been using the code below to extract the current user directory in order to read and write to certain files, presumeably independent of whether or not the user has administrative privileges. This has been necessitated in Win 7 because applications installed in the customary C:/Program Files(x86)/ are not allowed full access to files in the installed app root directory. This was working just fine until just this week when suddenly, for the first time, I found that the user directory retrieved was different when the app was run without administrative privileges in 'Start without debugging' configuration, both in Debug and Release configuration. Note that I have tested the identical app on Win2K and Vista and in neither case is it a problem on those OS machines. More mysterious is the fact that this ONLY happens on Win7 (VS2010 Ultimate) when run in the IDE. Run from the windows explorer double click, the app runs just fine in release and debug mode and monitoring the debug version using DbgView indicates that the expected 'Roaming' User directory is retrieved.
For example:
- without debugging (both Debug and Release configuration) the code below produces:
Either this has been the situation from the outset and I just never noticed it (hard to imagine as I've been on this project for 6 months with 50+ builds), a recent Windows update has changed things, a bug, or I'm just plain stupid (not hard to imagine at all).
From a practical standpoint, if this is the way things are to be, my installer will need to install necessary files in both user directories and the app will need to access both depending upon user privileges.
Code: /// This routine retrieves the process's environment block /// using GetEnvironmentStrings, parses that block pointed to /// by the generic international text pointer LPTCH, and returns /// the requested string lpszVarStr as a string. /// Note that the block lpvEnv environment variable substrings /// are separated by NULL byte, and the block is terminated by a NULL byte. /// The header files <windows.h>, <tchar.h>, <stdio.h>, <string>, and /// <iostream> need to be included.
i need to write a program that when run makes another exe file . Eg: make a program named 'sxes' and compiled it. When i execute or run sxes a new exe file named 'new01.exe' is created. This new01.exe when executed must input two numbers and add them and print output. I want to write a program same as installer file .
Is there any way to set a "lock" on certain couts from system ("cls"). You can this with const to "lock" a variable to a certain value so I am wondering if that is true for couts from system ("cls"). This would make my program much simpler to write.
I'm having a little problem with std:fstream - in my program, the user selects the location of a file which I want to remember. So, I have something like this:
Code: std::string fileLocation; //Code here creates an 'open file' dialog box which lets the user choose which file to open. //The string 'fileLocation' now contains the path to the chosen file. std::ofstream prefs("prefs.txt"); if (prefs.is_open()) { prefs << fileLocation; prefs.close(); }
This works fine if the file chosen is in the same directory as the program, however, if they try to choose a directory outside of where the program is kept, it saves the text file into that directory instead of the same one as the program. So, it looks like outputting a directory into an ofstream actually changes the location to which the file is saved.
Is there a way to save the file directory to a text file using ofstream and still have the text file save in the same directory as the program?
Been away from c++ for a few months now (apart from answering a few questions on this site). I was trying to see if I could do a simple program using just my memory that involved unique_ptr's, but getting an error:
"attempting to reference a deleted function". I thought that by getting a reference to my pointer would not invoke a copy constructor but i'm clearly wrong.
So I'm trying to create a program that allows one to read/write on to output.txt. I though I had everything set up right, but its only writing one word to the text file. Heres the code.
#include "stdafx.h" #include <iostream> //Needed for User Input #include <fstream> //needed for ofstream #include <string> // needed for strings #include <windows.h> //needed for Sleep #include <cstdlib> //Needed for return EXIT_SUCCESS;
using namespace std; int main() { ofstream outputfile; //allows to read and write to files
[Code] .....
If I type Puppies Are Cute and go to output.txt, the only thing written in the text file is Puppies.
I'm trying to write a program where it asks the user for a file name.
If that file exists, the it will open the file and then read it and print the information in the file.
However, if the user enters a file name that does not exist, the user will have 2 more tries (for a total of 3 tries) to get the correct name of the file.
I am close to getting it. What I have now just won't go through the loop to validate if the input matches an existing file. It goes straight to the printing of what is in the file. If the file doesn't exist, it prints: "Found your file..Opening..processing...Total keys found = 0."
So, my question, what am I doing wrong that it won't go through the loop properly?
#include<iostream> #include<iomanip> #include<fstream> #include<string> using namespace std; int main() { bool fileFound = false;
Say I have an object and 10 pointers to it in several other objects of varying class types. if the object gets deleted, those pointers have to be set to null. normally I would interconnect the object's class with the classes which have pointers to it so that it can notify them it is being deleted, and they can set their pointers to null. but this also has the burden that the classes must also notify the object when THEY are deleted since the object will need a pointer to them as well. That way the object doesn't call dereference a dangling pointer when it destructs and attempts to notify the others.
Auto pointers and shared pointers are not what I'm looking for - auto pointers delete their object when they destruct, and shared pointers do the same when no more shared pointers are pointing to it. What I'm looking for is a slick method for setting all pointers to an object to null when the object destructs.
I have a small questions in the behavior of Structure, I have declare a structure with 10 components. Some of the components in the structure has already their value but when I use
The structure components in a function DLL function those value I set previously has been deleted or empty. I don't know what is the problem...
I need my Unix program to generate a directory with a format like this: "hinesro.<pid>". I have some code that mostly works, except for the directory ends up with a question mark on the end, like this: "hinesro.12345?". I need it to just display the directory without this question mark. Here is my code:
Code:
// Using headers sys/types.h, sys/stat.h, unistd.h, and stdio.h int pid = getpid(); char prefix[] = "hinesro."; char fileName[0]; sprintf(fileName, "%s%d ", prefix, pid);
Error Message: $ ./dirsearch ~/Documents/College/textfiles/ [..] [yomama.txt] Error : Failed to open entry file - No such file or directory
Here are my current file permissions: textfiles$ ls -l total 8 -rw-rw-rw- 1 jav jav 7 Apr 26 13:14 moretext.txt -rw-rw-rw- 1 jav jav 10 Apr 26 12:38 yomama.txt
This program will allow the user to input string then scans the file if it contains the same string given by the user. But i always get "MATCHED" even if i enter random string. I tried and tried to place the if statement in different positions but i dont get my expected output.
Code: #include<stdio.h>#include<stdlib.h> #include<time.h> #include<string.h> int main() { int found;
A program which takes input from user and write it to a file then it reads data from that file then it should search for specific data such as email adresses or url etc.
I get the error at the line "ptr1 = new node;" I tried putting a default constructor for my node struct and that fixed the problem but a new problem arises. It states that i have a linker error after i compile it with a default constructor.
