C# :: Combining Or Merging PDFs From Several Memory Streams
Jul 7, 2014
merging 2 or more pdfs using itextsharp. I have 2 methods that fill a pdf template each and saves them to a memorystream and a downloadAsPDF methods to return the combined pdfs to the broswer. the downloadAsPDF works when i add only one of the memorystream but when i add both MemoryStreams to the list I receive the message...If this message is not eventually replaced by the proper contents of the document, your PDF viewer may not be able to display this type of document.
public byte[] fillTemplateA() {
String NfoodAllergyTemplate = "~/pdfTemplateA.pdf";

I wanted to know if i could use two streams with a file
fstream fS;
ifstream read;
fs.open("text.txt", ios::in | ios::out | ios::app);
read.open("text.txt", ios:: in);
my aim is to read a record from text.txt in to fs and compare it with other records of text.txt by read
bool checkID(char userID, inStream read);
read.open("text.txt", ios::in);
while (read.good()){
read.getline(id, size);
if(strcmp (id, userID)==0)
return true;
}
return false;

The goal is to write a c++ program to read the employee.dat(which is this text file below) file created and produce a duplicate copy of the file named employee.bak.
Anthony A 10031 11.82 12182010
Burrows W 10067 12.14 692011
Fain B 10083 10.79 5182011
Janney P 10095 12.57 9282008
Smith G 10105 9.50 12202006
and then the second question is to modify this program to accept the names of the original and duplicate files as user input.
#include <iostream>
#include <fstream>
#include <cstdlib> // for exit
#include <string>
using namespace std;
int main() {
ifstream inFile;
ofstream outFile;

I have dabbled in programming with C, but I am not proficient enough to write a program dealing with files. I have to take an extremely long list of numbers that need to be placed into another file within a line of code for validating purposes. Taking the numbers from one file and placing them into another file with a string code around them?

How I could use unions to combine registers elegantly. For example I have the 8 bit registers B and C & I have opcodes that work on each independent register such as add b, c, which is simple, but then I also have opcodes that work on both of them as if they're one like ld a, bc. I know I could go about that by just masking them together but I've seen it done with unions before & it made everything so much more simple.

So I built an interpreter for a language I made, but I can't get the streams right. I have an istream pointer and if they don't supply a cmd line arg, it references the adress of cin, which works fine. however, if they do supply a file in the form of cmd line args, i want to make it reference an ifstream. how do i do that?

#include <stdio.h>
#include <ctype.h>
#include <string.h>
void interpose(char s[], char a[], int pos) {
char b[80];
[Code] ....
The program should take 2 string parameter and 1 int parameter for combining. (without any str functions, the functions should be written by coder)
My problem is when i enter int value program crashes.
For example,
str1='Good';
str2=' Morning';
int x= 5;
The output will be 'Good Morning'

Write a program that uses a record structure to store a Student Name, Student ID, Test Scores, Average Test Score, and Grade. The program should keep a list of test scores for a group of 6 students. The program should ask for the name, ID, and four test scores for each student. Then the average test score should be calculated and stored. The course grade should be based on the following scale:
Average Test Score Course Grade
------------------ ------------
90 - 100 A
80 - 89 B
70 - 79 C
60 - 69 D
59 or below F
A table should be displayed on the screen listing each student's name, ID, average test score, and course grade. Implement with functions.
My code runs but it isnt returning anything (readable/correct) and i have no clue why. This is what i have so far:
#include <iostream>
using namespace std;
const int columns = 4;
struct StuRec //user defined datatype {
int id[6];
char names[6][20];
[Code] .....
it compiles completely but at the end instead of showing the student name ID average score and class grade it shows.... [URL] .....

I'm having a bit of trouble with something. What I'm trying to do is create a new Access table by combining other already existing Tables.
For instance, let's consider Table1 (with columns A, B and C), Table2 (with columns A, D and E) and Table3 (with columns A, F and G), where Table1.A = Table2.A = Table3.A.
From these, I want to create a new table TableResult, with columns A, B, C, D, E, F and G, with all the data contained in them. There's one catch: I want the code to get the names of the other columns, apart from column A.
I've thought about using Union, but I need to actually create a new table by combining the previous tables.

I want to write a template that combines two type of resources:
class someClasses {
typedef someType ElementType;
} template<class T1,class T2>
class combo {
...
}
And I want to specify my T1 and T2 has the same ElementType, how can I write my combo class to partial specialize the general case so the ElementType check is at compile time?

I have to implemente the to_string method. Whats the fastest way? Stringstreams. But I have to use C++ without any headers, so I need to implement the stringstream class. How can an stringstream hold one float? An double? Hoq cqn I implement an strigstream myself?

I need to make a program which reads multiple lines from a text file and stores that information in a vector of structs(the vector class template also needs to be custom made).
One of my requirements is to have a class dedicated for I/O for the text file. At the moment I can't seem to get a way to input the data from a file into a vector from an InputOutput class. This is my code:
InputOutput.h
#include <ostream>
#include <fstream>
#include "Share.h"
#include <string>
#include "Vector.h"
class InputOutput {
[Code] ....
This is the menu selection function in the menu.cpp where i figured i would call the Input file and store it from case 1. I think I'm doing it wrong though. Is there a better way of doing this because at the moment i am getting some errors such as error LNK2019.
void Menu::UserMenuSelection() {
Vector<Share> shares;
std::ifstream infile;
switch (menuOption) {
[Code] ....

I seem to be missing a concept or 2 here ... I am tasked with writing a program that reads text from a file and outputs each line to the screen as well as to another file PRECEDED by a line number ...
In addition, I have to Print the line number at the start of the line and right-adjusted in a field of 3 spaces ...
Follow the line number with a colon then 1 space, then the text of the line.
Another kicker, is I have to grab the data 1 character at a time and write code to ignore leading blanks on each line.
Here is what I have so far:
#include <iostream>
#include <conio.h>
#include <fstream>
#include <string>
#include <cstdlib>
#include <cctype>
using namespace std;
int main() {
char next;
int count = 0;
[Code] ....

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 need to write a c++ code which can merge contents of several .txt files into a single file. i used the following code , it works but after merging the result file contains the contents merged twice.I think it over writes the result.I want to do it without using command line.
#include<iostream>
#include<fstream>
using namespace std;
int main()
{
std::ofstream("merge.txt");
system("type *.txt >> merge.txt");
system("pause");
return 0;

The directions are to write a program that reads sorted integers from two separate files and merge the contents of the file to an output file (third file). The only standard output will be any errors to be reported and a “FINISHED” statement after all items have been processed.
file1.txt
2
4
6
8
10
file2.txt
1
5
11
12
15
Output.txt

This is the code I have so far, but it is not working, and I have put the two txt files in the same directory as my .cpp file. It is not working though still. What have I done wrong and how can I fix it to read these integers from the two numbers and merge the contents into a third file?
#include <iostream>
#include <fstream>
using namespace std;
int main() {
int num1;
int num2;
ifstream inputFile;

Write a program using user-defined function to merge the contents of two sorted arrays A & B into third array C. Assuming array A is sorted in ascending order, B is sorted in descending order, the resultant array is required to be in ascending order.

i've just started learning building structures in c++ and they gave us an exercise of writing a recursive merge code of linked lists - just merging without sorting... i don't even know how to start this is how i started so far.... i know that the break in the recursive function is when i get to the end of the first list and then to start linking the second list..as you can see i wrote a function that uses recursive function...
LIST merge3(LIST lst1, LIST lst2) {
LNODE* curr1 = lst1.head;
LNODE* curr2 = lst1.head;
LIST mergeList;
mergeList.head = NULL;
mergeList.tail = NULL;
