Visual C++ :: MFC - FrameWnd Output To Picture Control In Dialog

I am working on a MFC application that I used for Image Analysis. I have a FrameWnd called MillChart that I use to generate an Image. This window is displayed at the run time in the application and not a part of the GUI dialog. It automatically resizes according to the different monitor resolutions and because of this there is a lot of empty space to the right of the MillChart. I was planning to add a picture control in the GUI dialog and redirect whatever is displayed in the MillChart to the Picture Control so that I can place my other elements (checkboxes, scrollbars etc) that I use in my app close to this MillChart and also set the size of the MillChart to a constant size.

Here is the code for positioning the elements (Note: I have only shown the MillChart position)

Code:
void CMainFrame::PositionElements()
{
CRect r, r2, r3;
GetClientRect(&r);
int mcs = r.Height() - r2.Height();
mMillChart->MoveWindow(r.right - r2.Width(),r.top + r2.Height(),mcs,mcs);
