Hello you guys. I'm working a bit on improving my C++ so I decided to mess around with screenshots. it's windows based an uses gdiplus and windows api. It gets your window with the windows api then handles the bitmap that it generates with gdiplus and saves it to a file.

The screenshot header file
#include <Windows.h>
#include <gdiplus.h>


#pragma comment(lib, "gdiplus.lib")
#pragma once

class Screenshot
{
public:
    Screenshot();
    ~Screenshot();
    void makeScreenshot(const WCHAR*);
private:
    ULONG_PTR token;
    int GetEncoderClsid(const WCHAR*, CLSID*);
};

The screenshot class

#include "Screenshot.h"

ULONG_PTR gdiToken;

Screenshot::Screenshot()
{
    Gdiplus::GdiplusStartupInput StartupInput;
    Gdiplus::GdiplusStartup(&gdiToken, &StartupInput, NULL);
}


Screenshot::~Screenshot()
{
    Gdiplus::GdiplusShutdown(gdiToken);
}

int Screenshot::GetEncoderClsid(const WCHAR* format, CLSID* pClsid) {
    UINT num = 0;
    UINT size = 0;

    Gdiplus::ImageCodecInfo* pImageCodecInfo = NULL;
    Gdiplus::GetImageEncodersSize(&num, &size);
   
    if (size == 0)
        return -1;

    pImageCodecInfo = (Gdiplus::ImageCodecInfo*)(malloc(size));

    if (pImageCodecInfo == NULL)
        return -1;

    Gdiplus::GetImageEncoders(num, size, pImageCodecInfo);

    for (UINT codec = 0; codec < num; ++codec)
    {
        if (wcscmp(pImageCodecInfo[codec].MimeType, format) == 0)
        {
            *pClsid = pImageCodecInfo[codec].Clsid;
            free(pImageCodecInfo);
            return codec;
        }
    }

    free(pImageCodecInfo);
    return -1;
}

void Screenshot::makeScreenshot(const WCHAR* filename) {
    int screenHeight = GetSystemMetrics(SM_CYSCREEN);
    int screenWidth = GetSystemMetrics(SM_CXSCREEN);

    HWND desktopWindow = GetDesktopWindow();

    HDC desktopDC = GetDC(desktopWindow);
    HDC captureDC = CreateCompatibleDC(desktopDC);

    HBITMAP captureBitmap = CreateCompatibleBitmap(desktopDC, screenWidth, screenHeight);
    SelectObject(captureDC, captureBitmap);
    BitBlt(captureDC, 0, 0, screenWidth, screenHeight, desktopDC, 0, 0, SRCCOPY | CAPTUREBLT);

    Gdiplus::Bitmap *bitmap = new Gdiplus::Bitmap(captureBitmap, NULL);
    CLSID clsId;

    int retVal = this->GetEncoderClsid(L"image/png", &clsId);
    bitmap->Save(filename, &clsId, NULL);
   
    ReleaseDC(desktopWindow, desktopDC);
    DeleteDC(captureDC);
    DeleteObject(captureBitmap);
}


Can't you use views? Although that might get you some performance problems.

I'm just helping. I mean you have been busy with this specific task for 3 month's if not more.

Yes it's indeed more secure to have your forum password the same as your IRC password

I have a first working version of the urban dictionary module here: https://github.com/Lenoch420/ud
The code needs cleanup work and depending on what people want some added functionality, for now it just works

I also just had the idea in mind for a minimum install script in bash which just pulls modules from git, compiles them and moves them to the scripts/ directory.

I did not join for practical reasons and to cope with it I went to another party but it sucked. It sucked so hard I just wanted to take the plane but well there was no plane anymore


And happy birthday phage you get those multiple women in your bed and have a sexy awesome party

Just check the link I posted. It explains how to execute a statement. It's just nothing more then defining an object and executing a method.

As a beginner you should better not touch Laravel right away. Especially if you want to learn it in while learning to find vulnerabilities. Laravel abstracts PHP too much. All the code that sanitizes your data is hidden in Eloquent or the Authentication Module and you will never be in contact with Security except maybe the encryption methods to store passwords

I recommend you start with simple one file scripts. try to look what happens when you don't use htmlspecialchars() on user inputted code. (Tip: try <script>alert("hello");</script>) and understand the dangers. And learn what goes wrong in the code for all other type of security flaws.

When you are confident in basic PHP and want to write a Web application, Go for Laravel. I use it myself and I think it's an awesome framework.
