i cannot seem to get the image to draw onto this window that i have created. i think it has to do with my HDC variable but im not sure
					if (pbyteImage != NULL)
						EdsGetLength(stream, &size);
						HDC dc = GetDC(evfWin->GetHWND());
						CImage image;
						CComPtr<IStream> stream = NULL;
						HGLOBAL hMem = ::GlobalAlloc(GMEM_MOVEABLE | GMEM_ZEROINIT, size);
						LPVOID pBuff = ::GlobalLock(hMem);
						memcpy(pBuff, pbyteImage, size);
						CreateStreamOnHGlobal(hMem, TRUE, &stream);
						CRect rect;
						GetWindowRect(evfWin->GetHWND(), &rect);

						SetStretchBltMode(dc, COLORONCOLOR);
						image.StretchBlt(dc, 0, 0, rect.Width(), rect.Height(), 0, 0, image.GetWidth(), image.GetHeight(), SRCCOPY);
						ReleaseDC(evfWin->GetHWND(), dc);
