I have been told to show some text document when our application starts up, it is an EULA. They gave me a word file and I saved this file in a .rtf format. I then wish to show this in a dialog box and found this on code guru: [URL]
Which seems to be a sub-class that will do all the formatting for me. So I use that class and then load in the .rtf file, using their setRTF method I just get an empty text box.
I just want to be able to show this formatted, somewhat pretty text from this document in my application as close as I can to the original document. Is there an easy way to do that? I could turn it into plain text, but I think that my boss would not be happy about that.
The problem was that I needed the text box to be marked multi-line.

I have almost a hundred names in a text file that I want to convert to email addresses and save to another file. I seem to have it working, but it doesn't print the full names in the email prefix. The output I'm looking for is Doe_John@livebrandm, but I'm only getting D_J@livebrandm. I'm not sure what I should specifically be reading up on that applies to this directly.
Code:
#include <stdio.h>
#include <stdlib.h>
int main(void)
{
FILE *fpin=fopen("namesIN.txt", "r");
FILE *fpout=fopen("emailOUT.txt", "a");
char first[20],last[20],inbuff[1500];
[Code]...

My objective is to create a file and save some text in it. But the twist is that file should be created in pdf format.
I have written following code:
Code:
#include<stdio.h>
Code:
int main() { FILE *fp;
char ch;
fp=fopen("file.pdf","w");
fprintf(fp, "%PDF-1.3"); //to initiate data storage in pdf file
printf(" Enter data to be stored in to the file:");
while((ch=getchar())!=EOF)
putc(ch,fp);
fclose(fp);
return 0;}
Now my file is created in pdf format, but when I open it by double click on it, it is not open and gives the message like: "Error in opening document. This file is damaged and could not be repaired."

Provide three menu options to format the text entered in QTextEdit to
(1) display the letters in capital letters
(2) display the text in red
(3) align the text in the center
I did the 2nd and the 3rd part but I can't find the capital letter part
Code:
if (name == "Color") {
textEdit->setTextColor("red");
}
if (name == "Capital") {
textEdit->??????;
}
if (name == "Center") {
textEdit->setAlignment(Qt::AlignHCenter);
}

I am trying to display some data in text format on a dialog and I am using a CString to do it. Below is how I coded it.
Code:
CString outputStr;
CString auxStr;
// Add header
outputStr.Format("");
auxStr.Format("%-7s%-20s%-7s%-20s%s
[Code] .....
But the output rows are not aligned as shown in the attached picture. There a two problems.
1. Data rows don't align with the header row.
2. When the first element of a row changes to two digits, the other elements are shifted.
According to MSDN [URL] ...., CString::Format() works the same way as printf(). I wrote a small program using printf() to do the same thing, and the output in the console are perfectly aligned.
What have I missed when doing the display in GUI?

I have installed VS 2010 and VS 2012. VS 2012 uses SqlServer CE 3.5 and VS 2012 uses SqlServer CE 4.0.The problem is that when a project uses a 3.5 file it tries to open it with 4.0 even if the app.config says to use the 3.5 provider. The version of the assembly is pulled right out of the GAC. I uninstalled 4.0 and the reference auto updated its version to 3.5.1. However after installing 4.0 again it changes to 4.0. The error I am getting is that 4.0 cannot open a 3.5 file....they changed the file format from 3.5 to 4.0 and they are not compatible.

The requirement is to capture statistics of uuid occurrences for ALIVE/SEARCH/BYEBYE (it can be all 3, combinations of 2 each, or one alone) in a dynamically populated file in run time.
I am able to print all 3 combinations, but not in combination of 1 or 2 e.g.
If my input.txt is like this :
uuid:22314754-a597-490b-8a93-02cfae01036b ALIVE 16
uuid:22314754-a597-490b-8a93-02cfae01036b BYEBYE 8
uuid:22314754-a597-490b-8a93-02cfae01036b SEARCH 8
uuid:50e65653-7525-485d-83bf-d293558c4264 ALIVE 32
uuid:50e65653-7525-485d-83bf-d293558c4264 BYEBYE 8
uuid:50e65653-7525-485d-83bf-d293558c4264 SEARCH 132
[Code]...
Code:
#include<stdio.h>
#include<string.h>
struct uid
{
char uid_val[100];
char state[100];
int temp_count;
int alive_count;
int search_count;
[Code]...
Gives the following output ->output.txt)
Device ID ALIVE BYEBYE SEARCH
uuid:22314754-a597-490b-8a93-02cfae01036b 16 8 8
uuid:50e65653-7525-485d-83bf-d293558c4264 32 8 132
uuid:55076f6e-6b79-4d65-6497-180373763bc1 113 112 111
uuid:T0100203354 1 2 3
I want to generalize the code such that uuid occurrence does not have to be all 3 (ALIVE/SEARCH/BYEBYE), the occurrences can be any combination and code should work. e.g my code gives wrong results when input.txt contains the following:
uuid:22314754-a597-490b-8a93-02cfae01036b BYEBYE 8
uuid:22314754-a597-490b-8a93-02cfae01036b SEARCH 8
uuid:50e65653-7525-485d-83bf-d293558c4264 ALIVE 32
uuid:50e65653-7525-485d-83bf-d293558c4264 BYEBYE 8
uuid:55076f6e-6b79-4d65-6497-180373763bc1 ALIVE 113
uuid:55076f6e-6b79-4d65-6497-180373763bc1 BYEBYE 112
uuid:55076f6e-6b79-4d65-6497-180373763bc1 SEARCH 111
uuid:T0100203354 BYEBYE 2

I have a multivalued function (created in some other software Mathematica) that looks like f[8.7,5.4]=4.8+8.7*I. In other words it's a complex valued function of two variables. I store the output of this function over a range of parameters in a text file that looks like:
Code:
f[1,2]=9.8+8.7I;
f[4,5]=5.6-5.21I;
.
.
I could store it differently if that is easier, but essentially I just want some c++ code to read this in and store it, either in a vector type structure or Dictionary? (I don't think a double array will work as I don't know how long list of data is in advance).

I'm having trouble reading my data from a .txt file into a structure of the format shown in my code. I've made my student database in the program below based on user input and I didn't have a problem with that, but now it's come to input from a file it's making it difficult.
My three tasks are:
(1) A table containing 1 row per student, containing the student ID number and all of the student's marks.
(2) Another table, containing 1 row per student, containing the student ID number and the average mark obtained by that student.
(3) The average mark for each subject.
The assumptions to be made are: The student ID can begin with a zero, and should therefore be read in as a string.The test data will contain 20 students but the program should be able to deal with up to 100 students.Assume there are no more than 4 different subjects.
So based on the first assumption I've arranged the data in the file in an order in which the student ID begins with a zero:
003953 Computing 38
003953 English 88
003953 Mathematics 29
003953 Physics 83
073241 Computing 63
073241 English 99
073241 Mathematics 32
073241 Physics 73
...for twenty students, 80 lines of data. Now, on the assumption they must be read in as strings, this is what's making it tricky to store in the structure because, I've got 80 ID numbers but 20 repeat themselves 4 times. Once I've got this data in the structure below the tasks I won't have a problem with because I can just base it on a user input program but the data's already stored instead.
Below is my code for user input associated with task (1). In this example the IDs are stored as ints but for the file they will be strings. It compiles fine, displays the data as shown in the assignment sheet, but I don't know how to get the data into my structure. I can store the data in a structure of three arrays using fscanf() no problem, but it's not very "workable" for what I need to do with it.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <stdio.h>

I was asked by a friend about validity of following function prototypes,
void func1(int = 0, int*);
void func2(int = 1, int& = 2);
void func3(int*, int& = 3);
void func4(int& = 4, int* = 0);
void func5(int& = 0, int = 1);
void func6(int = 5, int& = 6, int* = 0);
I think the only prototype that is invalid is func1 because it does not have default parameter on the far right.

The following code writes to a file on either local disk to a remote disk (commented out code) on Windows 7 platform.
Code:
#include <iostream>
#include <fstream>
using namespace std;
int main () {
ofstream outfile;
[Code].....
The documentation does not specify what is a valid filename (path and filename). For example, will the "\server emp" path work on all operating systems to access a samba share? Does the constructor accept forward and backward slashes as folder separator on all operating systems?
