Use the Shell function to start the other application. Call the InstanceToWnd function to get the new program's Window handle (hWnd). Then use the SetParent API function to reparent the new window so it has the PictuerBox program as its parent.
If you want to free the new window from the MDI form, use SetParent to restore its original parent.
