text-files

I wrote a method which takes in a file name, checks if the file exists and has content, then proceeds to read 6 numbers in the file into 6 int variables and return true . If the file doesn't exist, or doesn't have content, it returns false. However, when I call the method and give it a file that exists, it returns false. I'm not sure where I went wrong. Here's my code: bool readHSV(string the_file) { if(ifstream(the_file)){ fstream myfile(the_file, ios_base::in); myfile >> h_min >> h_max >> s_min >> s_max >> v_min >> v_max; cout << h_min << endl << h_max << endl << s_min << endl << s_max <<

i made a program that uses a pre-made text file that hold a list of sites. now in some computer the program works fine but, in my friend computer it doesn't. i check the program on 2 of my windows 7 computers, and 1 xp and i don't have any errors. this program was used for some time on XP, now my friend want to install it in his windows 7 computer at home, but the program doesn't find the file after he install the program. this is the error he get: System.IO.FileNotFoundException: file not found 'C:\Users\eli\AppData\Roaming\fourmlinks.txt'. file name: 'C:\Users\eli\AppData\Roaming\fourmlinks

What is the fastest way to count lines and words in a text file in pure ANSI C? A word is terminated by a space or period. Line is terminated by '\n' . This seems to be in C++. Maybe take a look at the source code of the GNU wc utility as this utility does exactly what you want. #include <stdlib.h> #include <stdio.h> #include <stdarg.h> typedef unsigned long count_t; /* Counter type */ /* Current file counters: chars, words, lines */ count_t ccount; count_t wcount; count_t lcount; /* Totals counters: chars, words, lines */ count_t total_ccount = 0; count_t total_wcount = 0; count_t total

I just was wodering if there's an equivalent to MySQL LOAD DATA INFILE statemnent in Oracle? I need it because I want to read from a huge textfile into a database table. BigMike Oracle gives the SQLLoader commandline utility. But it relies on a proper formatting of the data file. You can try to look at Oracle External Tables (e.g. you can link a csv file as an external table and see it as a table within Oracle). Both solutions have pros and cons, but the big cons is that they still rely on data input format (so if you have a file ready for mysql, you may need to tweak it a bit). Example on

I'm working with a very big text file (755Mb). I need to sort the lines (about 1890000) and then write them back in another file. I already noticed that discussion that has a starting file really similar to mine: Sorting Lines Based on words in them as keys The problem is that i cannot store the lines in a collection in memory because I get a Java Heap Space Exception (even if i expanded it at maximum)..(already tried!) I can't either open it with excel and use the sorting feature because the file is too large and it cannot be completely loaded.. I thought about using a DB ..but i think that
