Call this function to enable a control bar to be docked.
Specifies whether the control bar supports docking and the sides of its parent window to which the control bar can be docked, if supported. Can be one or more of the following:
CBRS_ALIGN_TOP Allows docking at the top of the client area.
CBRS_ALIGN_BOTTOM Allows docking at the bottom of the client area.
CBRS_ALIGN_LEFT Allows docking on the left side of the client area.
CBRS_ALIGN_RIGHT Allows docking on the right side of the client area.
CBRS_ALIGN_ANY Allows docking on any side of the client area.
CBRS_FLOAT_MULTI Allows multiple control bars to be floated in a single mini-frame window.
If 0 (that is, indicating no flags), the control bar will not dock.
The sides specified must match one of the sides enabled for docking in the destination frame window, or the control bar cannot be docked to that frame window.
