When I am giving elements for row 2 ,program crashes .it says access violation.
Code:
#include<iostream>
#include<vector>
#include<string>
using namespace std;
void matrix_init(vector<vector<string>>& v)

I am really desperate on trying to make my code work. The code is to find the eigen values of any given matrix of dimension NxN. The input can be the diagonal of any NxN matrix alongwith its subdiagonal. The code works fine for N~350 or so but when i go beyond that these errors appear.
First-chance exception at 0x00425ea4 in divide.exe: 0xC0000005: Access violation writing location 0x01141000.
Unhandled exception at 0x00425ea4 in divide.exe: 0xC0000005: Access violation writing location 0x01141000.
But as i have never declared any variable statically and when i dynamically allocating memory with variables it should work like it does for smaller N values.
Here is my code so far, the problem is when I debug it I keep getting the same error but everything seems to be correct.
The error is: Unhandled exception at 0x00ED8F34 in ENCDEC.exe: 0xC0000005: Access violation reading location 0x00000008.

I recently started learning C++ and wanted to deep a bit into process memory reading for Windows, but I get an error I don't know how to fix. I'm using Visual Studio Express 2013 as my IDE and it tells me this, when I try to run and debug:
"Unhandled exception at 0x77E3E243 (ntdll.dll) in readProcessMemory.exe: 0xC0000005: Access violation reading location 0x00000043."
The Call Stack window says following:
ntdll.dll!_NtRaiseException@12() Unknown
ntdll.dll!_KiUserExceptionDispatcher@8() Unknown
ntdll.dll!_RtlInitUnicodeString@8() Unknown
> readProcessMemory.exe!main() Line 8 C++
[External Code]
And in the Output window is this: First-chance exception at 0x77E3E243 (ntdll.dll) in readProcessMemory.exe: 0xC0000005: Access violation reading location 0x00000043. Unhandled exception at 0x77E3E243 (ntdll.dll) in readProcessMemory.exe: 0xC0000005: Access violation reading location 0x00000043.
My code should be extremely simple, I'm just trying to find a Windows window. But here's the code.
Code:
#include <windows.h>
#include <iostream>
using namespace std;
int main(){

I have these two functions listed below. DoEvent() gets called from a window procedure whenever some event occurs. SetEvent() sets an element of the m_Events array a pointer to a Command object to handle the event. The array is zeroed in the constructor.
The error occurs on line 16 in the code in DoEvent(). Why the array is suddenly unreadable. When I call SetEvent() it works just fine, no problem.
When I step through the debugger in SetEvent i see that each element begins as 0 and the element I set is set properly. However, when I step through DoEvent() all elements in m_Events show "?????" "Unable to read memory".
uw::Command* uw::WindowBase::SetEvent(uw::WindowEventsEnum event, uw::Command* command) {
if (event < 0 || event >= FINAL_EVENT_ENTRY)
return NULL;
Command* ret = m_Events[event];
m_Events[event] = command;
return ret;

I'm trying to make it possible to have a 2 dimensional linked list with syntax like with vectors:

This code works:
//void Fighter::LoadAnimation(...){
std::list<SCML_SFML::Entity*> entities;
for(std::map<int, SCML::Data::Entity*>::iterator e = data.entities.begin(); e != data.entities.end(); e++) {
SCML_SFML::Entity* entity = new SCML_SFML::Entity(&data, e->first);
entity->setFileSystem(&fs);
entity->setScreen(&window);
entities.push_back(entity);//problem line
}
}
But if i change entities to a member variable, std::list<SCML_SFML::Entity*> Fighter::m_entities, it does not. Instead i get a write access violation when i try to push_back(entity). i need it to be a member variable because i need to use it in other member functions.

I have the following method to read in a data file using a struct and a doubly linked list.
The readFile method is as follows:
Code:
struct contact *readFile(char * FName,struct contact **ptrList) {
struct contact *head, *newContact;
FILE *fptr;
char oneLine[60];
char *sname, *fname, *phone,*company, *email;
[Code] .....
My struct definition is like this:
Code:
struct contact {
char sname[15];
char fname[15];
char phone[15];
char company[15];
char email[15];
struct contact *prev;
struct contact *next;
};
I have been given a task to debug a C++ project. I have not written a single line of code in this project!!
This project executes for about 5 minutes without problem. Then it ends with an exception "Unhandled exception at (some .dll name) in EITos.exe: 0xC0000005: Access violation reading location "
Now every time I execute the program. The error is from a different dll. Sometimes it is a dll created by other programmers, sometimes it is related to QT. So I don't think this is a code problem. Is there any project setting that would affect this?
I am trying to use PCA, but it gives memory access violation error. Here is my sample code.

I get a memory access violation when I run the below code. void createNewImage(int width, int height); this function deletes any current image data and creates a new image with the specified width/height and allocates the needed number of pixels dynamically. The new image contains four blocks with different color, red, blue, green, and black.
Code:
#include <iostream>
#include "image.h"
image::image() {
pixels = NULL;
width = 0;

The program works on my Windows x64 machine, but it causes a 0xc0000005 (Access Violation) error on the machine I want to apply it to (a Windows NT 6 v7600 x64 server).
The permissions of the NT machine are NT Authority/Network Service, I'm not allowed to change it due to security reasons. Is there a way to avoid this error?

I am trying to make a grid in DirectX, but I keep getting the error "Access violation writing location" for some reason.
This is my code for defining the grid:
void CDirectXFramework::DefineGrid(int Rows, int Cols, float dx, float dz, const D3DXVECTOR3& center) {
/* precalculations */
int CellRows = Rows - 1;
int CellCols = Cols - 1;
float width = (float)CellCols * dx;
[Code]...
What does it look like the problem might be?
btw, the values I am using are:
Rows = 100;
Cols = 100;
dx = 1.0f;
dz = 1.0f;
center = D3DXVECTOR3(0.0f, 0.0f, 0.0f);
I found that the program works when using these values for the rows and columns:
Rows = 2;
Cols = 2;
Using any other value gives the error mentioned above. It displays a small flat surface where I want it to, but I am trying to have a large enough surface to use as a ground (like 100 x 100).
I am getting an Unhandled exception at 0x00CB569E in AusitnHorton_Chapter17_7.exe: 0xC0000005: Access violation reading location 0xCCCCCCCC.

I'm trying to make a menu object in SFML. So far all I've added is the ability to add buttons with text inside of them. I store the buttons in a vector and then loop through that vector to draw the buttons.
The error stems from line 24 of the 2nd piece of code.
Here's what I've got:
//MenuTest.h
#include <SFML/Graphics.hpp>
#include <string>
#include <vector>
class Menu1 {
class Button1 {
sf::RectangleShape body;

This causes an error at the line window.draw(text); in Menu::Button::drawButton(). With the error "Access violation reading location (some memory address)".
Everything up to trying to draw the text works fine.

I would like to copy one bmp file to another using plain fstream (none 3-rd party library). I've managed to come up with something but I keep getting error:

when i try to write the content of the bmp files not the header, namely error occurs in this line:
Code : ofs_differential.write((char*)&picture, (bfh_warm.bfSize - bfh_warm.bfOffBits));
Also i am not sure if i am doing it in a right way, meaning that even after solving this error i will copy the bmp file successfully.

Today, I just received this new fresh error, I was constantly using them, but just come to know it is a private access violation as the last error of my program. Did I use it in the wrong way?
