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

	GetEncoderClsid(L"image/jpeg", &imageCLSID);
	int result = (pScreenShot->Save(lpszFilename, &imageCLSID, &encoderParams) == Ok);
	delete pScreenShot;

	return result;
}

 int APIENTRY WinMain(HINSTANCE hInst, HINSTANCE hPrev, LPSTR lpCmdLine, int nShowCmd)
{
	// for (int count = 26; count > -1; count -= 2)
	// {

	// }
}

nu reusesc sa il fac sa faca screen la intervale de 10 min... nonstop pana dau kill la proces.

Va rog frumos sa ma ajutati. Multumesc frumos.

[cifratorul]

pai si cum ai incercat? ai pus si tu un timer ceva sa apelezi functia la un anumit interval?

[Maximus]

@cifratorul ; am incercat asa :

for (int count = 26; count > -1; count -= 2)
	{
	Sleep(19000);
		return GetScreeny(L"screeny.jpg", 75);
	}

pe langa alte variante.. si nu a mers.ce e drept, nu sun PRO, iar codul nu e facut de mine, e luat de pe google

@noVaLue ; sa inteleg ca nu am ce sa ai fac?

Din moment ce un return se executa in functia main (WINAPI) programul se opreste, pentru ca el considera executarea completa a blocului de informatii, si intoarce un raspuns.

spide iti sugerez cu caldura sa termini macar un tutorial de C sau C++ inainte sa te apuci de astfel de proiecte.

Iti recomand Learn C++

@phreak ; mersi. Vroiam doar sa il las in lege sa faca print din cand in cand ... oricum multumesc de ajutor.

te-ai chinuit aiurea cu timeru ala cand puteai foarte frumos sa dai Sleep(1000 * 60 * 10)

[noVaLue]

I-am dat o idee despre timer, cum ar putea sa il foloseasca, poate vrea sa faca ceva mai complex stiu ca nu ajuta la nimic in proiect, de aceea i-am facut o structura.
