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.

The CAN Dll Code
int receive_data(unsigned char *data_output, int *MsgId, XLportHandle g_xlPortHandle){
XLstatusxlStatus, xlStatus_new;
XLevent xlEvent;
unsigned intmsgsrx=RECEIVE_EVENT_SIZE;
char *local_data ="11111111";
DWORD status;
xlStatus_new = xlSetNotification(g_xlPortHandle, &h, 1);

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

I need a code in c++ . It should count the Files and Directories in root folder with every folder information i need the below information
1) no of files and folder
2) how many files are there in each folder
3) with size of every folder and files it contains
I am new in c++ ....
I want to make a launcher for my program but the installation folder is different from one computer to another so I need a function or something that shows the path of the executable file.how to import a file from another folder.
#include<stdio.h>
int main(void)
{
FILE *fp;
*fp=fopen("C:Documents and Settings...something.txt","r");
}
You see I want to set the import path.
i get the name of file upon every OK click in the list of array.
i want the file name to be written in command prompt to install the file like
C:WindowsSystem32msiexec.exe filename.exe /quiet
fi is array representing the files
following is a code ..
foreach (FileInfo fiTemp in fi)
{
p2.StandardInput.Write("msiexec.exe ");
p2.StandardInput.Write(fiTemp.Name);
MessageBox.Show(fiTemp.Name);
}
Say, I have the "K: est del USB" folder.
Then I do the following:
Code:
SHFILEOPSTRUCT sfo = {0};
sfo.wFunc = FO_DELETE;
sfo.pFrom = L"K: est del USB";
sfo.fFlags = FOF_ALLOWUNDO |
[Code] ....
So when I run it, the SHFileOperation API shows this warning:
Are you sure you want to permanently delete this folder?
If the end-user clicks "No", SHFileOperation return 0x4c7, which I believe is ERROR_CANCELLED.
My question is, if I don't need any UI, how can I know that my file/folder will be permanently deleted vs. placed into the Recycle Bin?
I'm writing a small function that gets as parameter a file's path and a folder's path, and copies the given file to that folder.
Code:
int copy_file(const char* source, const char* folder) {
char copy[PATH_MAX];
strcpy(copy, folder);
strcat(copy, "/");
strcat(copy, source);
[Code] ....
Basically, this function purpose is to make a backup of source in folder every X minutes (depending on user's input).
The problem is the second call to open():
This call attempts to open the file for writing, and creates it if it is not already exist.
It also truncates it before writing to it - and that's my concern:
Let's say this is the second time this function runs, so copy is already exist. open() will then truncate it, and then one of the system calls in the while loop fails.
In this situation, I might be left with no backup file.
The problem also arises for when source is a read-only file:
If source is a read-only file, and copy is not already exist (meaning - it's the first backup attempt), then everything's fine, but, if source is a read-only file and copy is already exist, then I have to first remove copy altogather, and make a fresh copy of source.
Making a backup with new name for copy every time copy_file() runs, will solve this problem, and how can this be accomplished?
I should say that I'd really prefer that copy and source will have the same names when copy_file() returns...
I am searching an API that can give me thumbnail(with large Icons) of all folders of all drive in Windows 7. Like

I am trying to use ini file for configuring my app.
But GetPrivateProfileString is not working.
I am using Windows 7. I tried "Wow64DisableWow64FsRedirection" also.
Not only this-ATLPath::FileExists is also not working.It gives an error code 0x80070002 which means:
"system could not find the file"
I just purchased Visual C++ 2010 Ultimate, to start my coding experience. Whenever I try to debug, it gives me this error:
The system cannot find the file specified
It can't find the .exe file, I even Googled it, and tried a few things, without any luck.
I can't debug anything and get an error whenever I try. Being able to release a program to run it works sometimes, but it's hit or miss. I've created a very simple program to show the problem. The error on the screen is a result of me trying to debug, but I actually received the same error when trying to release as well.

So I'm doing a kind of banking system. Atm I've got the user able to create an account and set the balance of it, which is written to a .txt file. However, I would like the user to be able to enter their account no. and the program to cout the account info on the screen. I will be adding more to the program later, but until I work out how to search for values in a .txt file, and print out values on that line I'm a bit stuck.
Code:
Main.cpp -
#include <iostream>
#include "create_account.h"
#include <fstream>
using namespace std;
int menuin;
int main() {
create_account creataccObj;

Sample .txt file -
// Account_no - Balance //

1002 150600

View 8 Replies View RelatedMy coin/money change code works when there can be an exact change each time, i.e. when the 1 cent option is available.
