Aspose.Cells 4.0.2.7 Save Issue

Aspose.Cells Product Family

I have a situation where workbook.Save is failing when running at the server root. The following code creates a zero byte file and produces a "Object not set to an instance of an object" error but when it resides in a subfolder it operates flawlessly.

Dim oFile As String
oFile = "~/Export/" & Context.Session.SessionID.ToString() & ".xml"
workbook.Save(Context.Server.MapPath(oFile), FileFormatType.AsposePdf)

http://somesite.com/ <--- fails

http://somesite.com/testfolder/ <-- perfect operation

It also produces incomplete worksheet saves when it saves to the Response object

workbook.Save("SomeReport.xls", FileFormatType.Excel2000, Aspose.Cells.SaveType.OpenInExcel, Response)

http://somesite.com/ <--- fails

http://somesite.com/testfolder/ <-- perfect operation

This may be caused by your IIS settings. Aspose.Cells doesn't have any difference with creating files in these situations.
