C#/VB.NET hide and unhide window for Excel Workbook

We have demonstrated how to use Spire.XLS for .NET to hide/show Excel worksheets. From Spire.XLS v 10.9.0, it starts to support hide the current window of Excel workbook by setting the property of workbook.IsHideWindow.

C#
using Spire.Xls;

namespace HideWindow
{
    class Program
    {
        static void Main(string[] args)
        {
            //Load Sample Document
            Workbook workbook = new Workbook();
            workbook.LoadFromFile("Sample.xlsx");

            //Hide Excel Window
            workbook.IsHideWindow = true;

             //Save the document to file
            workbook.SaveToFile("result.xlsx", ExcelVersion.Version2013);
        }
    }
    
}
VB.NET
Imports Spire.Xls

Namespace HideWindow
    
    Class Program
        
        Private Shared Sub Main(ByVal args() As String)
            'Load Sample Document
            Dim workbook As Workbook = New Workbook
            workbook.LoadFromFile("Sample.xlsx")
            'Hide Excel Window
            workbook.IsHideWindow = true
            'Save the document to file
            workbook.SaveToFile("result.xlsx", ExcelVersion.Version2013)
        End Sub
    End Class
End Namespace
