Hi,

I am trying to set the visibility of an Excel sheet to xlSheetVeryHidden.
But I am getting an HRESULT: 0x800A03EC exception.

The code is given below:
Microsoft.Office.Interop.Excel.Application m_Excel;
Microsoft.Office.Interop.Excel.Workbook m_WorkBook;
Microsoft.Office.Interop.Excel.Worksheet m_worksheet;

m_Excel = new Application();
m_Excel.Visible = false;
m_Excel.DisplayAlerts = false;
m_WorkBook =
m_Excel.Workbooks.Add(XlWBATemplate.xlWBATWorkshee t);
Worksheet sh = (Worksheet) m_WorkBook.Sheets[1];

sh.Visible = XlSheetVisibility.xlSheetVeryHidden;

At the last line above I get the exception. Stack Trace is here.

[COMException (0x800a03ec): Exception from HRESULT: 0x800A03EC.]
Microsoft.Office.Interop.Excel._Worksheet.set_Visi ble(XlSheetVisibility

sourceControl, String eventArgument)
System.Web.UI.Page.RaisePostBackEvent(NameValueCol lection postData)
System.Web.UI.Page.ProcessRequestMain()

Does anyone know the solution. I just need to hide the sheet. That's all.

Thanks in Advance.
