C :: Create File To Write Text And Read Back The File Content
Mar 15, 2013The Objective Of This Program Is To Create A File To Write Text And Read Back The File Content. To Do That I Have Made Two Function writeFile() To Write And readFile() To Read.The readFile() function works just fine but writeFile() doesn't.
How writeFile() function Works? when writeFile() function Execute It Takes Characters User Type And When Hit Enter(ASC|| 10) It Ask "More?(Y/N)" That Means What User Want? Want To Go Next Line Or End Input?
If "Y" Than Inputs Are Taken From Next Line Else Input Ends.
But The Problem Is When Program Encounters ch==10 It Shows "More?(Y/N)" And Takes Input In cmd variable.If cmd=='Y' I Mean More From Next Line Than It Should Execute Scanf Again To Take ch I Mean User Input.But Its Not!!! Its Always Showing "More?(Y/N)" Again And Again Like A Loop.
Code:
#include <stdio.h>
void writeFile(void);
void readFile(void);
int main(){

C/C++ :: Write Function For Destruction Of Planetary System Solid
Dec 18, 2014I have to write a function for the destruction of the planetary system "solid". With the destruction of the planetary system, the asteroids where the gap between this one and the object, is smaller that "gap" will also be destructed. (so, they have to be deleted) The asteroids for which the gap is greater are converted to free-floating planets so they have to be inserted into the tree of free-floating planets. The total cost of the transport of all the asteroids that are converted into free-floating planets in the tree of free-floating planets should be $O(n)$, where $n$ is the maximal between the elements of the tree of free-floating planets of the star system to which the object belongs and the elements of the tree of asteroids of the planetary system of which the object has identifier "solid". The field "gap" of the new tree should have the value $0$. The destructed planetary system should be deleted from the list of planetary systems of the star system to which it belonged. (The tree of free-floating planets is not a binary search tree)
I have done the following: [URL]
Is the way I deleted the nodes correct??

C# :: Adding More Than One Content To Scrollviewer
Apr 20, 2014 I'm trying to create an appointment time table.
I used a ListBox with each ListBoxItem representing 15 minutes. Now I want to add some kind of label/picture next to the Listbox to indicate the hours.
What I did was I got rid of the scrollbars and scrolling ability of the ListBox and I heightened to the max. THen I added it into a Scrollviewer to scroll up and down.
Now I also have a StackPanel with TextBlocks. Each TextBlock is an hour label.
I want to put that StackPanel into the Scrollviewer as well so it can scroll alongside the ListBox! But it seems the Scrollviewer can only have one "Content" in it.
A picture of my program:

Here is my XAML so far:
(In this code my StackPanel is actually currently in Scrollview. I want to add my ListBox in as well...but I can't... />/>

C++ :: RAM Disk And Pointer To Content In File
Mar 3, 2014When we are using RAM DISK - the files are stored on the RAM. From what I understand (and saw many examples) in order to read data from file (the file which locate on the RAM) - I need to use the read function.
Is there a chance to get char* (or any pointer) to the content of the file without using the read function ?
If the file locate on the RAM, it seem that it is like I have a buffer on the RAM (like an array which was dynamic allocated) and in the case of a buffer on the ram -> we can use pointers to the data without reading all the data.
example:
class CDATA {
int nValue1;
int nValue2;
double dValue3;
double dValue4;
char achBuf[10];

C++ :: How To Put String Content Into Source Code

C/C++ :: Vector Content Goes Away As Soon As Method Ends
Apr 2, 2015I have this class, Prenumeratorius, it represents a subsriber in this context. Then I have a class Leidinys, which represents a newspaper:
class Leidinys {
private:
string kodas;
string pavadinimas;
double vienetoKaina;
[Code] .....
So in while loop it just reads data, Then I create Prenumeratorius object and store data in it, then I want to add it to correct place by using DėtiPrenumeratorių(), I will show it's content in just a moment. And the last method call - I just add element to another two way list of all subscribers.
So here is content of DėtiPrenumeratorių():
void LeidiniuSarasas::D/>ėtiPrenumeratorių(string kodas, Prenumeratorius &P) {
for(LeidiniuMazgas *dd = p; dd != NULL; dd = dd->Pirmyn()) {
if(dd->Imti().ImtiKodą() == kodas) {
dd->Imti().DėtiPrenumeratorių(P);
}
}
}
It just loops through all newspaprers and searches for the match. I actually tested this method, it works just fine, the problem is one step further:
As you can see, it calls another DėtiPrenumeratorių() method, this time that method puts Prenumeratorius in the vector I showed at the beginning.
The problem is, that when that method is over, vector's content dissapears, I debuged program and saw that, but I can't recognize what is wrong, I added & to all of my method's headers where it accepts that Prenumeratorius object. The same algorithm used to work with one way list.
C++ :: Member Function To Shuffle Content?
Nov 14, 2014Is there member functions for STL's like vector,list etc., to shuffle the content of that STL.
eg:
int arr[] = {1,2,3,4};
std::vector<int> v1(arr, arr+ sizeof(arr) / sizeof(int) );
now i need to shuffle the data randomly like
Now vector may contain {3,2,4,1} or {2,1,4,3} ...
I have taken vector as an example. let me know if there is any alternative way with other STL's
C :: Appending Content In Middle Of A Text File
Sep 18, 2013A 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:
Code:
#include<stdio.h>
#include<stdlib.h>
#include<conio.h>
#include "var.c"
int check_count();
void add_query();
void add_reply();
}

C++ :: How To Read All Content From A Text File Into A String
Sep 24, 2013I'm trying to read all content from a text file into a string. This is the code I'm using for it (I know there are other, maybe better ways to do it but I'd like to stick to this for now):
char* buffer;
std::string data;
FILE* fp = fopen("textfile.txt", "rb");
if (!fp) {
printf("Can't open file");
[Code] ....
So my problem is that I get an exception when I try to free the memory -> 0xC0000005: Access violation reading location 0x51366199
I even get the exception when I try to free it immediately after calloc() but why this is.
And if I use buffer = (char*)malloc(lSize); I don't get any exceptions.
So, why this fails and what I'm doing wrong.
C++ :: How To Store Entire Content Of File In Variable
Jan 28, 2013I would like to store the entire content of a file in a single c-string variable or in a standard string class variable. Is there a function that will do this for me? I am familiar with functions that get one character or one line at a time but I don't think I've encountered a function that gets the entire file. Does this function keep or disregard the end-of-line character? If no such function exists, I would write my own function to create and return such a variable.

Jan 13, 2014In my program I have to load a page in a second window based on user's decision. This is how I do it:
case 1:
Page1 p1 = new Page1();
secondwindow.frame.Source = new Uri("p1.xaml", UriKind.Relative);
secondwindow.Show();
break;
case 2:
Page2 p2 = new Page2();
secondwindow.frame.Source = new Uri("p2.xaml", UriKind.Relative);
secondwindow.Show();
break;
The user should not be able to navigate between these two pages, and between choosing one or the other page, the user will have some interaction with the main window. For the user interaction with the main window, the second window gets hidden:
if (secondWindow != null)
{
secondwindow.Hide();
}
Now if the user selects the first page and and then the second page, when I show the second window, I can see the first page for a fraction of a second, and then second page gets rendered. I wanted to know if there is a way to make sure the rendering is complete before using:
secondwindow.Show();
C# :: How To Represent A Table That Contains Dynamic Content In Header
Jun 2, 2014I've attached an image that shows a basic table with dynamic content in the header.
Initially, I thought about using a datagrid. However, I can't use a datagrid because of the format of my data visually. The DataGrid would not allow me to have static and dynamic data inside my column headers.
You see anything I am displaying in brackets, {}, are being updated with results after I process some data in the backend. After the data analysis is done, the results are displayed based on an algorithm.
So, let's say for control1, for each family, it would indicate whether the data passed or failed. Then, in the rows themselves, it would update with choice 1 or choice 2 depending on the data generated.
So, the data that is in brackets shows properties being updated. I'm not sure what UserControl I can use to accommodate this kind of display.
C/C++ :: Search In File And Extract Content Between 2 Strings
Jun 8, 2014I need to develop a simple program, i have 2 variables (begin, end), and i need to search in a file, And extract the string between the Begin and the End variables to a new File, For Example:
my text file: file.txt:
some text here<StartHere>more text here</EndHere>text text
C++ Program:
//Declear 2 variables
strcpy_s(begin, string("<StartHere>").c_str());
strcpy_s(end, string("</EndHere>").c_str());
//And now, search in the Text file, And Extract the text between the begin string and the End string.
<...>
The Result should be: NewFile.txt with the content:
<StartHere>more text here</EndHere>
That's it!, Here is what i have for now:
#include "stdafx.h"
#include <iostream>
#include <fstream>
#include <vector>
using namespace std;
int main() {
int ocurrences_count = 0;
int ocurrences2_count = 0;
char word[20]; //this array will save user input

Visual C++ :: Resizing Controls And Text Content
Sep 11, 2013I have a SDI application that uses a CFormView class to create a window and this window has 2 buttons and 2 edit boxes.
I can resize this window, like minimize and maximize, but the controls all stay at the same place.
I know that it's possible to move the controls based on window size.
But what i want to do is, as the window is expanded the controls and it's text content to grow proportionally and same when the window is shrinked.
Is that possible to do? i.e., increase/decrease size of controls and texts per window size.
