Remarks

You create a scroll-bar control in two steps. First, call the constructor CScrollBar to construct the CScrollBar object, then call the Create member function to create the Windows scroll-bar control and attach it to the CScrollBar object.

If you create a CScrollBar object within a dialog box (through a dialog resource), the CScrollBar is automatically destroyed when the user closes the dialog box.

If you create a CScrollBar object within a window, you may also need to destroy it.

If you create the CScrollBar object on the stack, it is destroyed automatically. If you create the CScrollBar object on the heap by using the new function, you must call delete on the object to destroy it when the user terminates the Windows scroll bar.

If you allocate any memory in the CScrollBar object, override the CScrollBar destructor to dispose of the allocations.
