I'm wondering if it's possible to adjust only the vertical of a frame/window/dialog?
I've searched various resources (including msdn), but I can't seem to locate (or figure out) how to go about adjusting a window/dialog/frame only vertically, only on one side; and also adjust a window/dialog/frame within an existing frame and adjust any other adjoining frames accordingly.
I know I can WS_SIZEBOX a frame, but that allows adjusting on all sides.
Set up would be something like;
Both ChildFrames are snapped within the MainFrame side by side. Adjusting the vertical bit in the middle, enables sizing both ChildFrame1/2. Not equally, but according to user adjustment.
Any tips or pointers would be much appreciated, thanks!
