I just created excel file using the class Excel writer. On my pc I have excel 2007. when try to open the file generated I have the following message:
the file are trying to open,is in a different format than specified by the extension. Verify that the file is not cprrupted and is from a trusted source before opening the file. Do you want open the file now?
If I press YES the file is opened correctly,but it is possible to eliminate that message?

It's a default message from excel 2007 when we try to open a document which we made with excel in older version (i.e 2003). The extension of excel 2007's document is *.xlsx and in 2003 version is *.xls
