When I do:
ef.Save(sUser & ".xls", SaveType.OpenInBrowser, FileFormatType.Default, Me.Response)
I want the excel file to open within the browser, not in Excel, in case the client machine does not have Excel on it. I want the functionality that Excel has, if I open an xls and save as htm. Then the htm will open in the browser, with tabs for each worksheet, and if my browser is IE, a menuitem is added to the File menu "Edit with Microsoft Excel for Windows" which will open the same spreadsheet in Excel.
How can I achieve this with Aspose?
