C#, Excel Workbook, SaveAs ( Exception from HRESULT: 0x800A03EC )

[fadi980]

Hi,

I'm exporting a data set into excel file from an ASP.NET application (VS 2008).
On my PC, i got everything working just fine. but on my client server i got the error ( Exception from HRESULT: 0x800A03EC ), and i found that the problem is in this call:

wb.SaveAs(FPath , Excel.XlFileFor mat.xlXMLSpread sheet, Type.Missing, Type.Missing, false, false, Excel.XlSaveAsA ccessMode.xlNoC hange, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);

wb is a workbook. FPath is the path to where i want to save the file, and i assigned user "everyone" a full control permission on this location.

on my PC i have WinXP, IIS 5. on client server it's Win server 2008, IIS 7.

i tried changing file format, i tried xlWorkbookNorma l, xlExcel12 .. but still the same error.

can any one please help me to know what could be different from what i have on my PC.

Thanks in advance

My first guess is you are using methods in one version of the framework that don't exist on the machine producing the error.
