Visual C++ :: Access Username / Password Protected URL?
Oct 14, 2014
I mainly code plugins for Cinema 4D .... I used to code in COFFEE (a javascript like language, only for Cinema 4D) and python. But, recently, I started coding in C++.
I start my development on a Mac, using Xcode. But then, to generate Windows versions of my plugins, I take my source code to Visual Studio, perform the necessary adjustments, and create Win32 and Win64 code.
Lately, I was trying to devise a scheme to protect my plugins from being pirated. Yes, I know it is virtually impossible, but if I could make it harder for hackers to crack my plugins, it would be fine.
I made it work fine in python and in C++, but only in Xcode.
In Windows it is difficult. I only need to be able to access a username/password protected folder in my server and check if there is a file there. I don't even need to read the content of the file (but it would be nice to be able to do that too).
I started out using the cURL library but it is so complicated to make it work. I need 32 and 64 bit versions. Then I also have to include three .dll files in the folder of the application (that means that I would have to ask to the people who buy my plugins to copy three additional files to the main application folder... not a good thing )
So, any way to access a username/password protected folder on the net? (the username/password is generated in my code so, of course, I know what are the username/password to provide).
Also, I would need a way for the code to be completely self-contained, meaning that the users would not have to manually add any other files (libraries), besides the folder containing my plugin.

I am trying to create a login that accepts a user login and password. it should accept 3 tries in which when the user enters their username the system should tell whether if the username is correct if not it should display a message saying invalid username and directs the user to register like entering their dob and name. But I cannot seem to get this part run correctly.
#include<stdio.h>
#include<conio.h>
#include<stdlib.h>
#include<string.h>
void main() {
char userId[10];
char passwrd[10];
int p = 0;

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.
[CODE]
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);
[code]...
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 tried to build a basic username-password verification program; I already have 2 text documents, usr.txt and pass.txt in which username and password are stored. Then have written this program to check the username and password, but every time it says Access Denied.
Here's what I have written:
#include<stdio.h>
#include<conio.h>
void main()

I am trying to make a simple login program that reads username and password from a text file.
In my text file I have:
name1;pass1
name2;pass2
name3;pass3
name4;pass4
name5;pass5
Everything is working okay with name1 and pass1, but if I try to log in with different credentials, for example name2 and pass2 it says "invalid details"
Here is my code:
string user, chuser;
string pass, chpass;
string los;
ifstream loginData("logindata.txt");
cout << "Please type in your username:" << endl;
getline(cin, user);
[code].....

I am doing C++ data structures exercises, and I am still learning some of the more basic concepts. I have a parent class:
template<class T>
class linkedListType {
public:
protected:
int count;
nodeType<T> *first;
nodeType<T> *last;
private:
};
Derived class:
#include "linkedListType.h"
template<class T>
class orderedLinkedList: public linkedListType<T> {
public:
void mergeList(orderedLinkedList<T> &list1, orderedLinkedList<t> &list2) {
first = list1.first;
...
} private:
};
There is more code in my mergeList() function, but I included the line that is giving me problems. The error that my CodeBlocks compiler is giving me is that 'first' was not declared in this scope.
Strangely enough, if I change it to this->first, the error disappears.
1. Why does it not recognise 'first'?
2. Why would this->first work at all? Is the 'this' object a smart pointer?

I have `MainShop`(base class) then `SwordShop` and `BowShop`(derived classes) and another derived class called `Inventory`. I have a vector under protected in my base class, and when I access it from my derived classes it's okay, but each one has its own value. How can I set them all to have the same value?
//MainShop.h
#pragma once
class MainShop {
private:
//some variables
protected:
vector <string> WeaponInventory;
[code]......
Here every time I run it, it goes straight to the `else` and it displays that I do not have any items. I want to just have one vector for both my bow and Sword shops because vectors take up a lot of memory and my teacher said keep them to a minimum. So I just want one vector that takes in items from my bow class as well as my sword class, but for some reason it's acting as if I have multiple vectors, each with its own set of items.

What I want is just to make a validation of the users and passwords already set within my array and go to the other form. By the way this form I already made it my start up form on program.cs with the same command I am trying to back to MainForm.
void Button1Click(object sender, EventArgs e) {
string error = "denied";
string[,] usrpass = {{"User1", "pass1"}, {"User2", "pass2"}, {"User3", "pass3"}, {"User4", "pass4"},
{"User5", "pass5"}};

I'm trying to create a simple program that reads in the user's first name, middle name, and last name. Then inside of the userName function, I want it to only take the first letter of firstName, first letter of middleName, and then just output the full last name. So for example: if your name was John Kevin Smith, it would output jksmith. I'm having a lot of compile issues due to the pointers. I have to use the function in this code, so the pointers are needed.
#include <stdio.h>
#include <string.h>
int main() {
char userName (char firstName[12], char middleName[12], char lastName[12], char firstInit[1], char secondInit[1]);
char firstName[12];
char middleName[12];
char lastName[12];
char firstInit[1];

I'm trying to create a piece of code similar to the code I have created on the new username section which will allow me to put certain restrictions on how my new users log in i.e the password length and the the need for a numeric digit. I also need storing my new members details in my previously created array.
case 'N': //Set up new user
Console.Write("
Create new Member details
");
Console.Write("
Create new Username
must be 8 characters, all letters, 1 Capital letter");

I don't understand why my compiler gives me this error when I'm trying to run this code:
Code:
#include <iostream>
#include <cmath>
using namespace std;
class Airplane
{
public:
Airplane();
~Airplane();
[Code]...
The variable is protected. Yeah, that's right. But shouldn't a derived class be able to reach it? Or is it only in a function that the derived class is able to reach protected variables and isn't able to reach protected variables in the constructor?

Is there a way to detect whether or not a template type has a protected destructor?
I see there is std::is_destructible in C++11, but I can't tell if this will return true or false for the protected case. Also, I'm interested in finding a solution for C++03 as well.

I have:
int _tmain(int argc, char* argv[])
{
printf("drive name: %s
", argv[1]);
It displays only the first character of the first argument on the command line.
Yet the following works as expected:
static char* myArg[2] = {"first arg","second arg"};
printf("drive name: %s
", myArgv[1]);
That displays the entire string "second arg".
So what's wrong with my reference to argv[1]?

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?

However, in debug version, whenever MemoryManager.Alloc(size) returns NULL, which means alloation fails, the AfxThrowMemoryException will cause the following exception:

I tried installing Java Accesss Bridge for a few hours now. But with no success. The installer from ORACLE does not work (rolls back at the end without error message). Many tries of patching some libs together failed.
What do I need for an application that makes use of JAB. Do I really need some sort of installation or can I simply put some headers and libs together?
