class CPrtPreviewDlgBar
This class implements the print preview dialog control bar. It is a modeless dialog that contains controls for manipulating a print preview window. It is loosely coupled from the print preview window to allow different controls bars to be used easily. In other words, the print preview window has no direct coupling to this class so this class can be replaced without affecting the core print preview logic. This class maintains an IQueryGuid pointer to the print preview window. That IQueryGuid pointer is used to get other interfaces for manipulating the print preview window. An example of a print preview window that is queried for is IZoom, which is used when the magnification value changes in the zoom combo box.
