Hey HF,
I released a video tutorial previously on how to make a stub and builder in C#. One of my friends decided to re-code my tutorial in C++ for HF. You can find my original C# tutorial here - hackforums.net/showthread.php?tid=4623639. I've posted his screen-casting on my channel, enjoy!

Stub (video) - youtube.com/watch?v=gb_xkgxGM68
Builder (video) - youtube.com/watch?v=iWo7a6Stg48

Stub - main.cpp

Code

#include <iostream>
#include <fstream>

#include <Windows.h>

using namespace std;

struct Settings {
int port;
char url[256];
};

int main() {
cout << "Stub\n\n\n";

long int filesize = 93184;
Settings data;

int size = MAX_PATH;
char *filename = new char[size];

GetModuleFileNameA(NULL, filename, size);

ifstream file(filename, ios::binary);
file.seekg(filesize);
file.read((char*)&data, sizeof(Settings));
file.close();

cout << data.url << ":" << data.port << endl << endl;

system("pause");

return 0;
}

Builder - main.cpp

Code

#include <iostream>
#include <Windows.h>

#include "MyForm.h"

using namespace System;
using namespace System::Windows::Forms;

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInst, char *cmdLine, int nCmdShow) {
Application::EnableVisualStyles();
Application::Run(gcnew Builder::MyForm());
}

Builder - form.h

Code

#include <iostream>
#include <string>
#include <fstream>
#include <msclr\marshal_cppstd.h>

struct Settings {
int port;
char url[256];
};

namespace Builder {

Nice tutorial, I'm sure this will help out a lot of people.

[tqmedia]

Very usefull tutorial. There is lots of good information for me

[еlixir]

Is there something equivalent to codedom in c++?

Yes, codedom.

[еlixir]

Codedom requires the .net framework. I need something that can compile without dependencies.

Hi Elixir,
Are you just looking to compile small C code? I like the TinyC compiler, great for malware. Let me know if you need help / thats not what you're looking for :P

Haven't heard of a library like that, however you could always whip one up yourself.

[Not2EXceL]

The CLI is real with this one. Seriously take the CLI out.

Instead of setting the filesize statically you can also get it dynamically

Replace stub with:

Code

#include <iostream>
#include <fstream>

#include <Windows.h>

using namespace std;

struct Settings {
int port;
char url[256];
};

int main() {
cout << "Stub\n\n\n";

long int filesize;
Settings data;

int size = MAX_PATH;
char *filename = new char[size];

GetModuleFileNameA(NULL, filename, size);

ifstream file(filename, ifstream::ate | ios::binary);
filesize = file.tellg();
file.seekg(filesize);
file.read((char*)&data, sizeof(Settings));
file.close();

cout << data.url << ":" << data.port << endl << endl;

system("pause");

return 0;
}

I changed the following lines

Code

long int filesize;

ifstream file(filename, ifstream::ate | ios::binary);
filesize = file.tellg();
