[C++]Kako narediti screenshot?

Zivjo zanima me kako v C++ narediti screenshot, ki ni extra velik? (torej v .jpg formatu).


Sem ze preiskal slo-tech in par drugih strani samo nisem mel se srece, da bi kaj delalo...

GDI+?

Vključiš knjižnico

#include <GdiPlus.h>

tukaj pa imaš funkcijo
ps: popravi pot kam ti naj shranjuje, če uporabljaš visto, 7, mislim da ne moreš shranjevat v c:, to funkcijo sem pobral pred časom z interneta...

void gdiscreen()
{
	SYSTEMTIME SysTime;
	GetLocalTime(&SysTime);
	wchar_t filename[200];
	memset(filename,0,sizeof(filename));
	wsprintfW(filename,L"C:\\screen%02d:%02d:%02d h.jpeg",SysTime.wHour,SysTime.wMinute,SysTime.wSecond);
	
	using namespace Gdiplus;
	GdiplusStartupInput gdiplusStartupInput;
	ULONG_PTR gdiplusToken;
	GdiplusStartup(&gdiplusToken, &gdiplusStartupInput, NULL);

	{
		HDC scrdc, memdc;
		HBITMAP membit;
		scrdc = ::GetDC(0);
		int Height = GetSystemMetrics(SM_CYSCREEN);
		int Width = GetSystemMetrics(SM_CXSCREEN);
		memdc = CreateCompatibleDC(scrdc);
		membit = CreateCompatibleBitmap(scrdc, Width, Height);
		HBITMAP hOldBitmap =(HBITMAP) SelectObject(memdc, membit);
		BitBlt(memdc, 0, 0, Width, Height, scrdc, 0, 0, SRCCOPY);
		Gdiplus::Bitmap bitmap(membit, NULL);
		CLSID clsid;
		GetEncoderClsid(L"image/jpeg", &clsid);
		bitmap.Save(filename, &clsid);
		SelectObject(memdc, hOldBitmap);
		DeleteObject(memdc);
		DeleteObject(membit);
		::ReleaseDC(0,scrdc);
	}
	GdiplusShutdown(gdiplusToken);
}

pps: več pomoči ti pa skoraj da ne morem ponudit, ker sem jo sam uporabljal in je funkcija delovala, tako da se nisem pretirano ubadal z njo.
