I’m trying to develop a c#/asp.net application to extract data from a SQL server

  • 0

I’m trying to develop a c#/asp.net application to extract data from a SQL server and have it formatted in an excel spreadsheet. I have been practicing with excel object model and recently stumbled upon this: http://support.microsoft.com/kb/257757 Considerations for server-side Automation of Office

From what I understand I really can’t use Excel Object models? And if not what are other solutions/advice besides whats suggested in this article and 3rd party apps I can use?

    From that article:

    Microsoft does not currently recommend, and does not support,
    Automation of Microsoft Office applications from any unattended,
    non-interactive client application or component (including ASP,
    ASP.NET, DCOM, and NT Services), because Office may exhibit unstable
    behavior and/or deadlock when Office is run in this environment.

    What this means is that Microsoft won’t explicitly prevent you from trying (the licensing allows you to try.) However, if there is a problem, it’s up to you to figure out how to fix it.

    There is a better option:

    Create Excel (.XLS and .XLSX) file from C#

    This will allow you to create the file for download without having to use Excel automation on the server side.
