Visual C++ :: Invoke AfxThrowMemoryException Cause Access Violation
Jul 25, 2014
I want to override the operator new in a class, as follows:
class CMyclass
{
public:
void* operator new(size_t);
void operator delete(void*);
[Code]....
However, in debug version, whenever MemoryManager.Alloc(size) returns NULL, which means alloation fails, the AfxThrowMemoryException will cause the following exception:
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 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:
Unhandled exception at 0x504A3442 (msvcr120d.dll) in ConsoleApplication1.exe: 0xC0000005: Access violation reading location 0x00380000.
when i try to write the content of the bmp files not the header, namely error occurs in this line:
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.
Code:
// ConsoleApplication1.cpp : Defines the entry point for the console application. // #include "stdafx.h" #include <iostream> #include <fstream> using namespace std; struct BITMAPfileHEADER { unsigned short bfType;
Code: std::ostrstream oss; oss << "path for " << unit << " " << path; puts(oss.str());
[Code] .....
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?
I have CAN Dll program for my application,which was separately used.Now I have included the Drivers program into my application Program and I am having this error System Access Violation Exception:Attempted to read or write protected memory.i am attaching the Dll code and Application code which is throwing this error.
My Application Code which is the receiver thread for accessing the messages got onto the CAN bus.
DWORD WINAPI Rcv_Msg(LPVOID param){ int*MsgId = new int;//msg id from CAN intRcvVal;//0 = there is data in the queue; 1 = there is no data unsigned int uMsgId; *MsgId = 0; unsigned char CanData[8];
I am trying to build a web application that uses p/invoke to access a method. Similiar to the one used here - [URL] However I keep getting the following error message - Unable to load DLL 'MyDll.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E) I read say to change the output directory to match that of the Mydll directory I have tried that and it still does not work.
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".
I have a problem. Im testing character movement in c++ and when i compile and run this, then try to press arrow keys it says "Access violation writing location 0x011feff4.Unhandled exception at 0x770a15de in test.exe: 0xC0000005: Access violation writing location 0x011feff4.The program '[8404] test.exe: Native' has exited with code -1073741819 (0xc0000005)."

I have a rather large project which uses a float array for OpenGL but I believe I am reproducing the problem with a simple example below.Essentially I am getting access violation and HEAP CORRUPTION errors when I execute the code below.
#include <iostream> #include <string> #include <sstream> int main(int argc, char** argv) { std::cout << "Please enter in the size of the array you would like to create:
I am getting the message Access violation reading location 0xccccccc8. when i try to print my dynamic array during the overloaded << function in my Flight class. where the error happens is surrounded by *s
//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 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.
I wrote a very small program in c++ to automate a process at work. The program basically fetches a binary file from somewhere on the internet, but feel free to look at the source:
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 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.
And, It puts a little yellow arrow at this line:
cout << nodepointer->value << " ";//print current node
when I try to run this program.
