Remarks
By default, the fpSpreadPreview control lets users zoom in and out in the view of the sheet pages.
If you set the value parameter to FALSE for the SpvSetAllowUserZoom function, users cannot zoom in or out by clicking the mouse while the pointer is over a preview page. However, you can still provide other means in the interface to let users zoom, such as a button that changes the SpvSetZoomState function's value parameter.
Return Value
SpvGetAllowUserZoom: For C users, TRUE if the function completes successfully; FALSE otherwise. For C++ users, TRUE if the user can zoom in and out; FALSE otherwise.
SpvSetAllowUserZoom: TRUE if the function completes successfully; FALSE otherwise.
