屏幕吸色器的實現

關鍵地方
1、::SetCapture(this->m_hWnd);ReleaseCapture();
2、::GetDC(NULL);獲得屏幕DC
COLORREF crtTMPColor;
CRect rect;
HDC hDC;
hDC = ::GetDC(NULL);
::GetWindowRect(this->m_hWnd, &rect);
crtTMPColor = GetPixel(hDC, (point.x+rect.left), (point.y+rect.top));
::ReleaseDC(NULL, hDC);
SetColor(crtTMPColor);
運行後截圖，小巧適用
