Generating Excel 2007 using string builder

[pavankasyapa]

Hi, How can we generate excel 2007 format document using string builder. We successfully achieved for generating excel file in 2007 format, but while opening the document it is showing a message as "the file you are trying to open contains a different format, are you sure you want to open it ". Can anybody tell me how can we avoid that warning message using source code (not with any registry settings etc).

Hi, This is not the right forum to ask the question. Btw, have you checked this link: http://www.dotnetspider.com/resources/38216-Create-Excel-File-using-ASP-NET-C.aspx[^]

There is no foolish question, there is no final answer...
