C++ :: CopyFile Error 5 - Access Denied
Dec 26, 2013
I am trying to copy files, but the windows + compiler gods will not submit easily today. In my code below I get the sysdirectory + the file I want to copy with:
GetSystemDirectory(sysdirect, sizeof(sysdirect)); //Sets system directory IE. C:WindowsSystem32
GetModuleFileName(GetModuleHandle(NULL), cfilename, sizeof(cfilename));
_splitpath(cfilename, NULL, NULL, fileName, extension); //splits the path name up into different pieces
_snprintf(rfilename, sizeof(rfilename), "%s%s", fileName, extension); // writes formatted data to a string
Then
if (strstr(cfilename, sysdirect) == NULL) { //returns a pointer to the first occurence of str2 in str1
char tmpfilename[MAX_PATH]; sprintf(tmpfilename, "%s\%s", sysdirect, filename);
cout << tmpfilename << endl;
[Code] ....
my tmpfilename prints exactly where I want it to go and my debug prints out an error 5 which is an access denied error. I was looking at the system("copy") function, but I don't think I would be able to use my pathnames. From what it looks like I would have to hardcode in like "copy C:windowssystem32".

I'm new to C++ and keep getting an error. I get a permission denied and id returned 1 exit status, the code is fine and as far as i understand this would be because my OS doesn't allow modification of currently running files which would make sense as when i look in task manager it shows my program running even though it has finished. Ending process/process tree does nothing as does using any third party process terminator.
There is no loop in the program or anything even a simple hello world program yields the same result. Only way i can re-run my program is restarting my computer or saving the project under another name and re-compiling...

I am writing a C++ program that finds the Word Documents on your computer that have '+' or "%2B" in the name and replacing those '+' and "%2B" with ' '. I am writing this program for my school's University Writing Center, so I predict the only places they will have these files are the USB memory stick, Desktop, Documents, and Downloads. I encounter a problem, however, when I run this program and it renames the files in Downloads: Permission denied. I am using the windows.h to do this. How do I give the program permissions to that folder?
update:This program is going to be written in C++.

let me show you the (simple) code:
Code:
#ifndef DUCK_H_
#define DUCK_H_
#include<iostream>
using namespace std;
class Duck
[Code].....
When I compile, it says: "error: 'virtual void Duck::display()' is protected" how come I can't gain access to MallardDuck's display(), which is public?

I upgraded to code::blocks and now I have the errors while trying to install sfml and sdl (to use in a dual project): Codeblocks libs:Permission Denied
Codeblocks libs is a custom folder I created and copied libs from the lib folders to because I got the same errors in the actual folders and thought it might be because of their location. What should I do?

My goal is accessing c++ objects within c by using wrapper and externals. To get the pointer to the c++ object I use a type "void *".
But i get an error while linking: undefined reference to "create_mycpp".
Should I take an other way to access c++ objects?
Code:
//-------------------------------------
//mycpp.cpp
#include "mycpp.h"
Mycpp::void func(int i)
{
i += 1;

if we don't provide the acces modifiers for base class and we need to manipulate the private data of base class in derived class. Is there anyway to acces the private data members? Here's a coding example
class A {
private :
int a;
};
class B : public class A {
public :
void displayA() { cout<<a<<endl; }
};
how i can acces the a of base class A in derived class B without acces modifiers.

Code:
#include <iostream>
using namespace std;
void f();
extern int x;
int main() {
[Code] .....
x is declared outside the functions and defined inside main(). Then why this code produces a compile error?
x is already declared so it can be used in f(); and when I call f(), x is already defined. Then why can't f() sets the value of x (in main) to 10?

I have an array called abee1.
int abee1[4][3];
I have done some string function (like: "abee" + "1" ) and have "abee1" as string which is the same as abee1. How can I copy the data of abee1 into another array with same size, for example abeeTwo[4][3], using only the name of abbe1 as string ("abee1") not by abee1 directly.

I have the following code below. I am getting a memory access violation when accessing cmd->query_string in the loop function. The loop() function is running in another thread. The cmd object appears to be destroyed after calling the send_command function. How do I create an object on the heap and access the query_string.
std::list<my_command_message_que*> my_command_que;
void loop(){
if(my_command_que.size() > 0){
my_command_message_que * cmd = my_command_que.front();
std::cout << cmd->query_string;

On linux, I can compile DLLs (shared objects) as well as executables that use them. I can even access globals and classes that are defined in the EXE from the DLL, and vice versa, simply with the 'export' keyword. flawlessly.
The Problem: But on Windows (using MinGW), no matter what I do, I'm completely unable to access global variables which defined in the EXE, from the DLL. On Linux, this is no sweat, but what's Windows' problem?
I also need to extend classes in the dll with base class method definitions defined in the exe.
Ive heard that on Windows, you need to use declspec(dllimport) and declspec(dllexport). I can compile with CygWin+MinGW/g++4.5.3 as well as "Pure Windows" with MinGW/g++4.7.2 *without* the declspecs. So what's the decljunk for? Is this really just something for MSVC or other compilers?
Here's some Windows code to show what the problem is. The DLL's global variable is accessible to the EXE just fine, but the EXE's global variable is not accessible to the DLL - compilation complains it is an undefined reference.
main.cpp
#include "myLib.h"
#include <stdio.h>
int exe;
[Code].....
edit: I tried using --enable-runtime-pseudo-reloc --allow-shlib-undefined options when compiling the DLL and G++ complains that --allow-shlib-undefined is an unrecognized option.

I found this API [URL] .... which proposes to do exactly what I want, but I need to develop it by myself.

In this code:
vector<int> mydata(100);
mydata[2] = 999;
In statement 2 does that call the iterator to access the 3rd position and set its value to 999?
