CView inplace editing of control layout
<p>I have a <code>CView</code> that acts as a placeholder for several Ctrl's stacked vertically so as the occupy all available space.  What I wish to do is grab a horizontal boundary with the mouse and drag it up or down to resize Ctrl height.</p>

<p>The problem being that the child Ctrl's of the <code>CView</code> intercept the mouse messages and not the <code>CView</code> parent window (<code>WM_LBUTTONDOWN</code>, <code>WM_MOUSEMOVE</code> etc).  The Ctrl's also handle these messages for unrelated editing requirements.</p>

<p>Would anyone be able to offer advice or supply a reference to possible solution(s) to this sizing/editing requirement.  The situation is some what similar to the resource editor in Visual Studio.  Only I wish to edit in a live environment.</p>
