The value set control supports dynamic resizing if the application sends the WM_SIZE message to a value set window. This means that the value set control automatically recalculates the size of the items when either the user or the application changes the size of the value set window.
If the value set window's size is decreased so that the window is not large enough to display all of the items the value set contains, the items are clipped. If scroll bars are desired to allow the clipped information to be scrolled into view, they must be provided by the application.
