I'm having trouble opening a file from a specific location.
#include "maidcafe.h"
....
char directory[80] = {"C:UsersPublicDocumentsAnime NotesTransaction"};
char code[20];
printf("Enter file name");
gets(code);
strcat(directory,code);
system("start "" %s",directory);
i thought this would work, but it didn't xD. I got an error
I have a huge text file in following format:

I want to extract Text1, Text2, Text3, Text4,..., Text600 in the output file. How can i achieve this?
/* BTW, I am not getting my homework done here. I am an ex-programmer, who has now moved to marketing for some time now, and today, I encountered this problem, which I believe can be solved easily through programming. */
I have a text file called (Test.txt) with the following text:
This is line one
This is line two
This is line three
How do I go about writing a program that will print a line of text (e.g. "This in line two" on the console screen?
All I can seem to do is display the entire text file.
I already wrote:
strncpy(buff2, buff1[i], strlen(buff1)-i );
but this function seem to just copy from the beginning of a buffer to another, not from the ith element.Is there such a function?
Buff1&buff2 are char[10000] and i is declared int, holding the interesting element's position.
How to measure a NAS (NTFS) free space/total space and used space? Few more details: I have the needed code to map the NAS location (serverNameshared_folderfoldersub_folder) into the local server where I am running my applciation but I can only get the needed statistics above for the whole NAS, I need to know the statistics for a specified folder on the NAS, how can I do that?
View 1 Replies View RelatedI'm trying to type out whatever is in the .txt document, but I cannot open it for some reason. My code is
Code:

I keep getting an error with my fp=fopen so how do you open the text? Do i have anything else wrong with my code.

I want to select three columns from my text file i.e. Empl No, Start Date and Created Date. After selecting this, I want to insert the data into a database.
I have attached a copy of the text file.
I have the following code so far:
if (File.Exists(filename))
{
string[] lines = File.ReadAllLines(filename);
for (int y = 0; y < lines.Length; y++) {
Console.WriteLine(lines[y].ToString());
}
How do i select specific details for each employee
I am trying to print a specific line from a textfile
e.g
I have a text file called info.txt and inside it contains the id,item name, price, quantity
Code:
1,shirt,100,10
2,pants,50,9
3,pen,20,8
I know how to find a specific word at the line in the file but how do I find and print out the specific line e.g(print out just the entire contents of line 2)?
Code:
string temDescription;
ofstream fout;
int curLine = 0;
[Code].....
I have the following complete code in c++
Code:
void GetMapData () {
MapPair NewMap;
string TempString;
BOOL SkipReadLine = FALSE;
//------
char buffer[MAX_PATH];
std::fstream File;
[code].....
The problem is that I do not want to have an external MapData.txt, rather I access it through a embedded text resource, which in this case I have no knowledge on doing so.
I have the following snippet which demonstrates to my knowledge on how to access a text resource; however, I do not know hot to modify the code above to implant this, but to still have the same functionality as the original code above.
Code:
HRSRC hRes = FindResource(GetModuleHandle(NULL), MAKEINTRESOURCE(IDR_TEXT1), _T("TEXT"));
DWORD dwSize = SizeofResource(GetModuleHandle(NULL), hRes);
HGLOBAL hGlob = LoadResource(GetModuleHandle(NULL), hRes);
const BYTE* pData = reinterpret_cast<const BYTE*>(::LockResource(hGlob));
note that I am compiling with a MBCS.
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 am in an "intro" C++ course and am having trouble with a section of my current project.
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];

I have started making a text adventure game.
if (Choice == 2) {
cout << "" << endl << "You follow the light to the end of the hallway, you find your self in a room" << endl
<< "with natural light coming from a hole in the ceiling." << endl << "" << endl << "You hear the door you just came through, slam behind you!" << endl << "" << endl
<< "There are three possible directions." << endl << "" << endl << "Do you:" << endl << "" << endl << "1) Go forward" << endl << "" << endl << "2) Go left" << endl

Ignore the if (Choice == 2) at the beginning, that's linked to some previous code.
I want to make the player go back to the first bit of text but i'm not sure how to do this if they keep choosing to go back and forth from one location.
I first thought of doing it by just putting the text back in after they have chosen the option, but I can't do this infinite times.
I am trying to change label text on button click, the way label.text = "string" work well before but not in this case. I tried to put this on other method and it work..it is just not working on the button that I would like to fire..

I want to open one new CMD from console application, write text into the new CMD and then coming back to the control on the old cmd. (like interactively working on the both)
look into the below code
Process P1 = Process.Start(@"C:WINDOWSsystem32cmd.exe");
P1.StartInfo.RedirectStandardInput = true;
P1.StartInfo.RedirectStandardOutput = true;
P1.StartInfo.UseShellExecute = false;
StreamWriter wr = P1.StandardInput;
wr.WriteLine("First line in New Cmd");
Console.WriteLine("First line in Old Cmd");
wr.WriteLine("Second line in New Cmd");
Console.WriteLine("Second line in Old Cmd");
it is giving the exception "StandardIn has not been redirected"
I have my libraries in ../../lib location
and when i try to compile :
gcc -O9 -I ../../include/ -L ../../lib/ -o test test.c thr.o -lm -lthread
I get :

obviously the problem is the library path location but my obj is there

I have a std::vector of short ints that I need to write to a specific location in a binary file (without using .NET code). To that end, I wrote up this code:
Code:
ofstream fileStream (filePathString, ios::out | ios::binary);
int curPos = 2821;
fileStream.seekp(curPos);
int iter = 0;
while (iter < 1024*1024){
char bytesToWrite[2];
//Low byte
bytesToWrite[0] = LOBYTE(dataVector[iter]);
[Code]...
The code runs without crashing, but when I look at the file afterwards in a hex editor, every byte (even those outside the range I thought I was writing to) are replaced with 00. I suspect I'm missing something in my understanding of file streams. Did I write that code correctly? Seekp does move the pointer over the next byte to be overwritten, yes? Am I getting a memory leak somewhere?
My project is to get a file from a designated location in my computer and not just read, but grab the values from the user and make a count, sum, and average calculation of the numbers in my code. I am using the fstream library and I am trying I did do it, I got the values and calcualated them, however I want the values to be accessed from maybe my desktop or my drive, I want to know how to manipulate my code to get a path like C:UserDesktop and maybe executed from the path input or given. I dont know if this is possible, or easy to do. ALso I did copy some of this code from my teachers examples and I dont know exatly why the variables have to be initilized at zero, and I would like to know a little more on the Bitwise right shift breaker used in line 20 something.
Here is my code below.
#include <iostream>//For avergae functionality
#include <fstream>//For the file commands, such as ifstream and the Bitwise right breakers(<< and >>).
#include <iomanip> // To control the amount of decimals in my results desired.
using namespace std;
int main () {
int aNumber=0; //Initilized at zero because of Stack Overflow:

I would like to copy one bmp file to another using plain fstream (none 3-rd party library). I've managed to come up with something but I keep getting error:
Unhandled exception at 0x504A3442 (msvcr120d.dll) in ConsoleApplication1.exe: 0xC0000005: Access violation reading location 0x00380000.
when i try to write the content of the bmp files not the header, namely error occurs in this line:
Code : ofs_differential.write((char*)&picture, (bfh_warm.bfSize - bfh_warm.bfOffBits));
Also i am not sure if i am doing it in a right way, meaning that even after solving this error i will copy the bmp file successfully.
Code:
// ConsoleApplication1.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"

#include <fstream>
using namespace std;

so I wrote this code in class today and I'm almost done but I need to come up with some sort of equation to add up all the total values. The problem is I am reading data off a txt file so it's all being read as one thing. I don't know how to get each specific value and add them all together. This is my code so far.
#include <iostream>
#include <iomanip>
#include <string>
#include <fstream>
using namespace std;
[Code] .....
here's what's inside the input file
Chisel 50 9.99
Hammer 30 15.99
Nails 2000 0.99
Bolts 200 2.99
Nuts 300 1.99
Soap 55 1.89
I end up multiplying the amount by the price to get the total value as shown in the code above. Now I just don't know how to add the total value of each item to get the total overall value. Also I haven't used invTotal because I want that to be the overall total.
