Writ a program to implement hashing of text files in a directory to find files with the same content?

I mean, instead of loading my dice images as "dice6.png", I'm trying to load them from a file, as ".Imagesdice6.png"
Not sure why, but this isn't working. Google searching has got me nowhere.
Ok I'm on a Windows machine and I'm writing a simple tool to dump and touch ttf files. It's almost done except that the command line parser is giving nightmares. how do I stop the shell from automatically converting wildcards in arguments to directory listings? (I first flatten all arguments to a single string before parsing)
View 7 Replies View RelatedI have built the wave tool and now am trying to run my source code through it. But it just doesn't want to find the include directory. I just don't understand. Here's my command:
#include <stdio.h>
#include <vector>
#include <map>
#include <string>
Perhaps it how I built it since there is no info on how to do this? I just ran ../b2.exe from the boost_1_53_0/tools directory.
I'm running CYGWIN_NT-6.1-WOW64 TARDIS 1.7.18(0.263/5/3) 2013-04-19 10:39 i686 Cygwin with a g++ version of 4.5.3. g++ has no problem finding the default include directory (I don't have to specify the -I switch). The -I switch doesn't seem to work for any of the other include directories that I wan to use either, but I want this cleared up before I get into that since it might be related.
I recently noticed that I don't need to include the required header files inside header files that I have written myself. As as example, GLuint is defined using typedef unsigned int GLuint; inside glew.h. If I create a sample.hpp header file and mention GLuint without including glew.h, the compiler automatically works out that there is a typedef in glew.h. However, if I mention GLuint in a source file the compiler starts to complain. I have seen this happen in VS 2010 and 2013.
Edit: I should have mentioned that I am not including any other header files so I'm not indirectly including glew.h
In case you need to look at the code:
#ifndef CP_SHADER_LOADER_H
#define CP_SHADER_LOADER_H
namespace cp {

msdos is present on my computer but it cannot include the header files but when i check all files are present but they still cannot include????????
View 1 Replies View RelatedI have two files that I want to compile:
main.cpp
Code:
#include <iostream>
using namespace std;
int ReadNumber();
void WriteAnswer();

The compiler complains:
io.cpp||In function 'int ReadNumber()':|

io.cpp||In function 'void WriteAnswer()':|
io.cpp|7|error: 'cout' was not declared in this scope|
io.cpp|7|error: 'endl' was not declared in this scope|
In io.cpp file, should I put the two statements ("include <iostream>" and "using namespace std") at the top, outside of the functions?
Or should I put the two statements inside each of the functions?
I'm a beginner with C and wonder how to include single header files (*.h) in to my project. I mean header files which are not included to the standard installation package.
I thought it would work if I just copy the newheader.h file in to library folder c:MinGWinclude, but it didn't work. Is there some kinf of GCC -command or procedure to add these single header files or how it should work?
All of those standard header files are working well and I don't have any problems with them.
Environment I'm using is MinGW+GCC+Win7.
if I include iostream twice in my project why is that valid? Wouldn't the linker see that there are two definitions of it and report a error, but it works?
By project I mean in multiple translation units.
I'm writing a program to merge all .txt files in a directory. I had the code working and then made small change. It started crashing and I couldn't get it back to working.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <dirent.h>
#include <unistd.h>
#include <string.h>
#include <sys/stat.h>
[Code] ....
It's crashing around the
Code: while(!feof(in)){ .
If I comment that section out, the code still works. But, I know that portion of the code works to copy text from one file to another! It's actually from the Schildt complete C reference and I have tested it several times on it's own.

I'm using the following code to capture all files in a directory - but when I pass the "path" var such as "C:SomeDir" ffd.cFileName is just simply "SomeDir" and is seen as a valid folder and no more files are processed..

write a code using vs studio 8 to read a diretory name as argument and then open the directory and read each file one at a time and find the match for a string passed as an nother argument in the lines of each file. When it matches create a file and write in that output file the file name whetre the match found, the line number and line which matched.
My vis does not have dirent.h. so please use another ways to read directory call witha system acll and then then extract the fienames in a file(use some primitive way to open the the directory)
I cant do this parts
(1) read a directory
(2) create a file with only file names
(3) read file names ans open the files one at a time till the end of the file reached
I've tried to form together the following code so that I can process multiple files from one user specified directory. However, when I run the program it works great for the first file, but all other files are blank. The problem starts on the following line:

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?
View 4 Replies View RelatedI am writing a piece of code that requires me to display the last 1000 lines from a multiple text files (log files). FYI, I am running on Linux and using g++.
I have a log file from which - if it contains more than 1000 lines, I need to display the last 1000 lines. However, the log file could get rotated. So, in case where the current log file contains less than 1000 lines, I have to go to older log file and display the remaining. For e.g., if log got rotated and new log file contains 20 lines, I have to display the 980 lines from old log file + 20 from current log files.
What is the best way to do this? Even an outline algorithm will work.
I'm reading from stdin a line. With that line, I should open a new textfile with the first letter of that line on a certain directory. My code is the following :
Code:
int main() {
char line[BUFSIZ];
FILE *ptr_file;
int x;
while(fgets(line,BUFSIZ,stdin) != NULL){
[Code] ....
char caminho[] is the directory in which I want to create the text file and chave will be the first letter of the line in stdin.
How am I supposed to use strcat to get these two together in a string to then use ptr_file =fopen(caminho, "w");
I want to write a single line to a file and upload it as a .txt file to a server directory . I know the traditional way to upload a local file to a server
public bool ftpTransfer(string fileName){

string password = "test";

is there anyway to change this so that I can write the contents of the file through the program and upload it directly without having a local file?
I'm trying to get a Browse Directory dialog to update a text box with the path selected. I had it working fine in Unicode build but now using TCHAR - I see the variable contains the correct path, but the textbox only gets updated with a single weird character.

I want to make a program that opens a text file and checks the usernames listed in the text files to see if the names are registered on a site such as twitter. How easy would this be to make, what things would I need to know?
View 4 Replies View RelatedI'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?
I found it incredible that I could not found any working example of simple printing text while I was looking on google.
Somewhere I read I should include (I am not sure if I remember the name right but code::blocks on Windows did not find the header)
Code: #include <stdiostream.h>
so I am trying
Code: #include <stdio.h> and cout << "test"; (error: cout undeclared)
or
Code: #include <stdio.h> and std::cout << "test"; also I tried print("test");
as noted somewhere on Answers. Did not work (error: undefined reference print).
Last try I even got most of links in French. So I hope you'll give me the correct answer. Edit: I found it. I used puts()
I have a text file that contains values as follows:
2013 05 27 15 52 02.049824 231.401 0.022 49.738 2013 05 27 15 52 02.668822 229.814 0.019 49.738 2013 05 27 15 52 03.283705 228.528 2.599 49.726 2013 05 27 15 52 03.898469 230.140 2.576 49.751
Column1=date, Column2=Month, Column3=Day, Column4=Hour, Column5=Minute, Column6=Seconds, Column7=Voltage(Vrms), Column8=Current(Irms), Column9=Frequency(Hz).
I have to develop a program that will analyse these time-sampled voltage and current measurements over 24 hours and find the total energy used, mean and peak power consumption and Energy used over each hour of the 24 hour period.
How do I go about doing this? I also need to include at least one numerical integration technique. The file data contains over 50 thousand lines in the format mentioned above.
