Cropping can be implemented by setting window region of the PictureControl.
Please identify region for cropping by tracking LButtonDown and LButtonUp messages.
Then set window region of the PictureControl

C++

  CRgn clipregion;
clipregion.CreateRectRgn( left, top,  right, bottom ); // Prepare clip region.
pPictureControl->SetWindowRgn(clipregion, TRUE);
