Like the Production Reporting menu option, the Viewer menu option displays all the methods in the SQR Production Reporting ActivatorActiveX Control. To use the Viewer menu, open an SPF file. (A few sample SPF files are included in the \sample directory of the Oracle's Hyperion® SQR® Production Reporting Activator installation.) All the menu items under Viewer call the Oracle's Hyperion® SQR® Production Reporting Viewer ActiveX Control’s methods or read/set properties, except for "Page Navigation", which uses the properties CurrentPage and PageCount to do things like first page, last page, next page, previous page and go to page. Notice that it does not make sense to call the SizeTo method other than from its containing (parent) window. As a result, it is called by the message handler for the frame window when processing WM_SIZE message.
You can have multiple reports open in an application, each in its own Viewer ActiveX control. The last option on the Viewer menu demonstrates this feature. It has four fix size controls on a window (you probably need to enlarge the window to see all), and the program helps you bring up four reports.
