Assembly: Microsoft.Office.Interop.Excel (in microsoft.office.interop.excel.dll)
If the range is discontinuous, the first area is used. If the range is more than one column wide, the leftmost column in the range is used.
If the window is maximized, this property returns a negative number that varies based on the width of the window border. Setting this property to 0 (zero) will make the window a tiny bit smaller than it would be if the application window were maximized. In other words, if this property is 0 (zero), the left border of the main Microsoft Excel window will just barely be visible on the screen.
