Post From: StudyRegionRightCoordinate Problem when

I have found a workaround to using sc.StudyRegionXXXXCoordinate to get my code to work. Instead I use GetClientRect() to fill "rc". Here is the full code:

  // Set up the memory device context we will draw to so we can apply transparency. Copy the current image so there is no strange
  // issue with the blending.
  HDC hMemDC = CreateCompatibleDC(DeviceContext);
  RECT rc;
  GetClientRect(WindowHandle, &rc);
  //rc.left = sc.StudyRegionLeftCoordinate;
  //rc.right = sc.StudyRegionRightCoordinate;
  //rc.top = sc.StudyRegionTopCoordinate;
  //rc.bottom = sc.StudyRegionBottomCoordinate;

  HBITMAP hBitMap = CreateCompatibleBitmap(DeviceContext, rc.right - rc.left, rc.bottom - rc.top);
  SelectObject(hMemDC, hBitMap);
  BitBlt(hMemDC, rc.left, rc.top, rc.right - rc.left, rc.bottom - rc.top, DeviceContext, rc.left, rc.top, SRCCOPY);

However, I would still like to understand why my original idea to use the StudyRegion coordinates does not work when there is a Trade Window attached on the left of the chart.
