It works well with Excel 2000 and 2003 but with Excel 2007 I've got a message saying that the format of the file I'm trying to open ,"Export.ashx", is different than the one specified by the file's extension and ask for confirmation (sorry my version is in french and I don't have the message in english...). How not to have this warning?
Could you elaborate which different results you get. Please provide us the complete details, you my provide us the sample codes, template excel file(s) etc. We will check it soon.
And for you info, this warning message is a user-notification function that was actually added to Excel 2007. The warning message can help prevent the unexpected problems that might occur due to possible incompatibility issues between the actual content of the file and the file name extension.
Well, It’s not the problem about Aspose.Cells. Please check the option about MS office and IE settings.
Coming to your resutls Results with IE7 and Excel 2007:
OpenInBrowser mode: Please check the issue in Microsoft support in
http://support.microsoft.com/kb/927009/us-en
OpenInExcel mode: We could not understand “you may have to be precise if you want to open or save the file, it depends on your parameters”. Could you explain it more especially about “your parameters”? We would appreciate if you could give us some snapshot(s) about this issue, we will surely check the issue ASAP.
OpenInExcel mode: Everything works well in this mode so I'm not waiting any further answer. The parameter I'm talking about is a security parameter in IE but I can't remember which one, sorry.
