This Code Append file successfully but when I Execute the appended Exe, only the first EXE will execute, why and how to fix it so that successively both of exe will execute .
A user enters a query and other users reply to it. But it creates a problem here. After adding queries, if I wish to reply to query in between then it adds a redundant entry in file. 1st entry is the original query without reply and 2nd entry is the same query now with a reply added. I want only 1 entry of the query along with replies.Here is the code:
Following is the program I wrote it basically takes 9 inputs and then save them into binary file. then print out the data stored in binary data and find inverse of it then print the inverse out. but its stuck in a loop somewhere.
Code: #include <stdio.h> int main() { int a[3][3],i,j; float determinant=0; int x; FILE *fp = fopen ("file.bin", "wb");
I'm having a little problem with System::String and terminating the text to end the line in the textbox, I tried adding to the string in multiple ways (Insert, or just + " ")) but the text is still appended in one single line.
However converting a properly terminated char array to a string and appending it to the textbox works. So, let me explain my code a little more: I have a function which appends text to the textbox (I use it from a different thread thus I needed to use Invoke):
But when I try to call it multiple times with different strings then they do not appear in new lines but they're all in one single line, I've tried doing it like:
I've also tried using Environment::NewLine, but it still didn't work, so what I finally came up with was converting the system string to an char array using Marshal and inserting an " " there and then converting it back to an system string, then it was ok .
I need to create a program which could create text files of the bits stored in avi file/binary file. My first requirement is to show 0s and 1s in the text representation . My second requirement is to create an avi file from this text file. I have tried few codings but either they give me error or they not playing the reconverted binary files.
I am trying to get the code to read from the txt file one bite at a time and then write this bite into the binary file but i cant seem to get it working.
FILE *fpcust, *fpcustbin; //<<<<<-----point to both sales and customers text files, and the new .bin files for both char buffer; int ch; int ch1; fpcust = fopen("c:customers.txt", "r"); //<<<<-----pointing to the file fpcustbin = fopen("c:customers.bin", "wb"); //<<<<<-----pointing to the new binary file, opening in writing binary
I just wrote a program for Huffman Encoding, where I take a text file, encode it in the form of 0's and 1's, and save that as another text file. However, this does not solve my purpose as it is taking even more space.
So I want to know how do I convert a text file containing these 0'S & 1's to a binary format.
When reading a binary .img why is it when you read it by slurping in the file, then save it to a string and cout, you don't see the binary but random garbage?
I'm not the best at C but I'm trying to write a C function that basically opens a text file with assembler language does a syntax error check on it and then converts the binary data into hex.
This is my code so far:
Code:
#include <stdio.h> #include <string.h> int main(void) { FILE*fname; char prompt; char filename[15]; char text[100]; printf( "Please enter the name of the file you wish to open: " );
As long as position+length doesn't exceed the end of the file, all is well. However, if it does, weird things start to happen. In particular, the apparent length of the file (that is, the value of "read" after the function has finished) becomes dependent on "length"). I know that "position" is never past the end of the file.
I'm attempting to split a large binary file into smaller manageable files for analysis. I've written most of the software but I'm stuck in a couple of places.
1. The binary file is split by looking at a couple of bytes to determine when to create a new file or continue appending to the current new file. The question is when I need to create a new file, how can I dynamically sign it a name? My intention is to rename each subfile by: "original_name" + new section id + ".log".
2. The start of each section is determined by a specific pattern (6 bytes of FF's). I'm running into an issue where the pattern check is checking for 5 bytes instead of 6 because the for..loop doesn't increment for one instance.
How to store values from a .txt file delimited with semicolons (;) into a class which is then stored into a Binary Search Tree. After browsing Google for a few hours, and trying various examples of people using Vectors, I just can't seem to get my program to work using Object Oriented Programming with an instance of the class Person.
My two classes are Person, and BinarySearchTree as follows:
class Person{ private: string first_surname; string second_surname; string name; int ID;
[Code] ....
Ok so my text file saves the data of each person in the same order as the class with each value separated by a semicolon.
i.e. First_Surname;Second_Surname;Name;ID;Telephone;Score;
void fillTree( BinarySearchTree *b) { string input[7]; Person p; fstream file("scores.txt", ios::in); // reads text file if(file.is_open()) {
[Code] ....
I understand that I get an error because a vector is saved as integers, and I am using strings, my question is, any other way to read the .txt file and save each data separated by a semicolon, into the Person class?
I a want to write a code to convert a string into binary data for that i wrote a code its working perfectly but there is one problem , some of the binary data is written in 7bit and i want to convert it to 8 bit by adding 0 to the last.
#include <iostream> #include <fstream> #include <string> using namespace std;
My program writes a vector to a file in binary. I want to erase the vector, then read the file to repopulate the vector then display.
Basically I want to erase the RAM memory and be able to use the file as memory. This is my current code but it is not reading the file correctly. I have checked the file to see that the writing part is working.
void read_from_file(vector<Info> &vector) {fstream file; file.open("info.dat", ios::binary | ios::in); if (file.fail()) { cout<<" FILE DOES NOT EXIST "; system("pause");
