I'm trying to edit an existing xml file but with no luck. I'm new to xml environment.
This is the xml content :
<?xml version="1.0" encoding="UTF-8"?>
-<mmp>
<ID>aaa</ID>
<clientID>bbb</clientID>
<time>2004-05-10T17:35:41.29</time>
<session>2000</session>
<Answer>Yes</Answer>
-<Program>
<_id>ppp</id>
</mmp>
I'm trying to change the time and id values and can't do it.I tried almost anything.
#include <iostream>
#include<fstream>
using namespace std;
int main() {
string choice, meaning, word, yesOrno;
char add[20];

i have done my best but i have still problem with searching words from previously saved words from user this code it keeps adding but it won't display when i search for.
Let's say I have an exe-file (for example computer game) and need to forbid to run it until certain date or time during the day. Any 'manipulations' with file are allowed. offer me a simple way of how to encode/decode such a file?

View 1 Replies View RelatedI've got some code in C++ that does some basic analysis on price data and I run it from the cmd prompt. One of the functions I had built to read in the data is as follows:
void ReadPricesFromFile(constchar*filename,std::vector<PriceInfo>&prices)
{std::ifstreaminput(filename);
input>>prices;}
How would one merge this type of code into a Qt GUI? Ideally, I'd like to use something like QFileDialog to open up a folder with my data files, select a file, and then read the file that the user selects. Would the main.cpp look something like this?
int main (int argc, char *argv []) {
QApplication prog (argc, argv);
QPushButton *load_button = new QPushbutton ("Load File");
QObject:: connect (load_button, SIGNAL (clicked()), &prog, SLOT ( (ReadPricesfromFile function?);
load_button-> show ();
return prog.exec ();}
I basically want to develop an application which print an existing file on reception of a network event (application will be running on a seven 64 bits PC).
I wonder which application type would be the most suitable (and the simplest) for that (console win32, win32 app, MFC app ...). As this application does not need user intervention (print on network event), I'm not sure that I need a MFC application or a win32 app.
Well,I have a dat file which following format;
ID Level(Manager or Executive)
Name
Sales(for 12months)
For example;
W00051 M
Lee Ah Moi
1200.00 150.00 1400.20 156.00 200.00 880.00 1500.00 8000.00 800.00 120.00 1600.00 1800.00
My question is how am i going to find the value 880.00 (August) & replace it with a new value?
Is it possible for me to open & edit the same file without creating s new one?

how to change a certain part of a text file? I want to +1 to a text file every time the user does a particular input. For example my text file has name << password << count . When the user logs in and choose option 1 the program will +1 to the count.
for e.g. Bob Bob123 1
when he logs in and chooses option 1.
it will change to Bob Bob123 2
What i'm trying to do is compile a text file to an executable, but the problem is that I want to be able to edit the resource file while in runtime, for example write something on a textbox, hit compile and get the executable file edited by the texbox.
Here's my codedom:
public static bool Compile(string sourcefile, string exefile) {
CSharpCodeProvider ccp = new CSharpCodeProvider();
CompilerParameters cp = new CompilerParameters();
cp.ReferencedAssemblies.Add("System.dll");

Is there anyway I could do that?
I have this project for school where I basically need to write a program that will take any text file and convert it into html code.
string line;
int lineCount = 0;
while (!inFile.eof()) {
getline(inFile, line);
cout << line << endl;
lineCount++;
}
cout << lineCount - 1 << " lines of text read in this file." << endl;
I have this block of code to print each line of the text file into the terminal window and count the number of lines printed. But I don't know how to make it change a single character or set of characters to something else. For example, if a line of text begins with the number "1", I want to be able to change it to "<h1>".
I have a report that's generated by a piece of software, and (I'm assuming because it was intended for Linux/Unix) when I open to read it in notepad, it has a bunch of funky symbols in it, and incorrect line feed characters instead of returns that windows uses.
I looked at the txt file with a hex editor and can see all the hex codes for the symbols I want deleted. One of the symbols 0A.
How can I do a "find and replace" command but do it with hex codes? These symbols cant be simply placed into my code file because VS does not know how to interpret it.
I am working on a program that will do several mathematical calculation and will store the data into a csv file.The one below is just a prototype version of this.In my program,I will store my csv file as (current-date).csv using time.
With this in mind,I want my program to first check does (current-date).csv already exists.If not,the program runs normally and output all the data into the csv file.
However if (current-date).csv already exists,I want my program to read and edit that particular csv file,by skipping part1 in my code(name,id N etc.) and start with prompting the user for numbers straight-away.
In other words, if (current-date).csv already exists,the user should continue outputting the numbers from where the user last left before last termination instead of outputting the name,date & etc into the csv file again.
Eg: if no=22, continue inputting values from no=23 till terminating the program again and storing the values correctly into the csv file.
#include <iostream>
#include <fstream>
#include <iomanip>
#include <locale>
#include <string>
#include <sstream>
#include <time.h>
using namespace std;
// Program to read date N store it as currentdate.csv

i am working on a resx file. I have read the file and load it on data-gridview. now i wanted to be able to edit from the file and save.I have tried many ways but i didn't come with the solution. yesterday i tried this code below. I don't know how i can edit. here is what i have tried,
private void btnSave_Click(object sender, EventArgs e) {
foreach (DataGridViewRow _row in Gridview_Output.Rows) {
DataRow dt1 = oDataTable.NewRow();
for (int i = 0; i < Gridview_Output.ColumnCount; i++) {

View 5 Replies View RelatedI have an array of char representing pixels in a bitmap, which I want to modify. I don't think I can just iterate over the array and pass chars into a function individually, because the function needs to take into account the neighboring pixels, too.
I thought of two ways to do this. The first would be to pass the array to the function as an argument, then have the function change it and return it. The trouble is I'm not exactly sure what happens internally when you pass an array to a function and return it. Is it the same array, modified? Or is it a copy of the array, so now you're using twice as much memory?
Alternatively I guess I could have a function with a void return type and pass a pointer to the array. I'm somewhat new to this, but the way I understand it is that a pointer is like the address of a house, while the array is the actual house. So if I give the function the address, it can go to that address and rearrange the furniture inside the house. Then, after the function returns, I can go to that address myself and see all the rearranged furniture, even though the function has already returned.
Is there a problem with the second way? It seems a bit neater, but maybe I'm understanding pointers wrong.
I would like to get hold of the code for a function that takes a string as input argument and returns a numerical value, either integer or double, according to the the expression represented by the string. For example the string may look like this:
Code:
"(256 * d3 + d4) * factor - offset"
then the function would calculate the value of
Code:
(256 * d[3] + d[4]) * factor - offset
where d is an integer array, factor and offset are double or int variables or constants. For my application the name for the array can be fixed to be "d", and the names for other variables and constants are known. The closest thing I could find on-line is this:
[URL]
which only does literal integer calculations, no double, no variables or constants. Are there existing code that does what I need or do I have to write my own?

Is there some quick way of resetting the contents of an existing array to 0? Just to be clear, I'm not initializing the array, it already exists, has content and needs to be reset at 0. Is there a faster way than the code below?
Code:
for(i=0;i<100;i++)myarray[i]=0;
is it better to reuse an existing variable or create a new variable for the following situation:
/* Is this faster: */
glm::mat4 newViewModelMatrix = (*existingViewMatrix) * (*existingModelMatrix);
/* Or is this faster? */
glm::mat4 existingViewModelMatrix; /* declared in class header - initial value assigned in class constructor */
existingViewModelMatrix = (*existingViewMatrix) * (*existingModelMatrix);
Just wondering if it makes a difference or not.
I am trying to add in a few 3rd party libraries to an existing project solution. I have no source code or knowledge on how the libraries were built (i.e. what run-time library was used). I have recieved the following errors and warnings:
1>CAPS_LIB.lib(PCEfunc.obj) : MSIL .netmodule or module compiled with /GL found; restarting link with /LTCG; add /LTCG to the link command line to improve linker performance
1>libcmt.lib(getenv.obj) : error LNK2005: _getenv_s already defined in MSVCRT.lib(MSVCR90.dll) ***There are multiple of these errors
1>LINK : warning LNK4098: defaultlib 'MSVCRT' conflicts with use of other libs; use /NODEFAULTLIB:library
1>MSVCRT.lib(cinitexe.obj) : warning LNK4098: defaultlib 'libcmt.lib' conflicts with use of other libs; use /NODEFAULTLIB:library
1>libcmt.lib(crt0.obj) : error LNK2001: unresolved external symbol _main
1>C:Program Files (x86)BCI 2000 v3progRelWithDebInfo..CAPSVRInterface.exe : fatal error LNK1120: 1 unresolved externals
CAPS_LIB.lib is one of the libraries I am trying to add in and it seems to be the one causing the problem. I believe I have added in all three libraries into the project solution correctly, but I can't seem to find a solution to these errors.
