SQL query to Office applications

strictly_mk asked
Last Modified: 2013-11-05

I'm using MS Visual Web Developer Express 2005 and SQL Server 2005 Express. I have a database backend and a few web pages for the front.

I am building a contacts database which is supposed to be able to create excel spreadsheets for mail merge data sources and also to be able to create Outlook contacts from the data stored in the database.

I have a gridview that shows the results of a database query with code like this...

Public Function generatedata(ByVal conn As String, ByVal query As String) As DataTable
        Dim connection As New SqlConnection(conn)
        Dim command As New SqlCommand
        command.Connection = connection
        command.CommandType = CommandType.Text
        command.CommandText = query
        Dim adapter As New SqlDataAdapter(command)
        Dim buffer As New DataTable
        Return buffer
    End Function

conn_string = "Data Source=.\SQLEXPRESS;AttachDbFilename=" ....
query = "SELECT * FROM Contact WHERE....
results = generatedata(conn_string, query)
GridView1.DataSource = results

I have check boxes on each row and I have code that takes the primary key (ContactID) for that table and puts them in an array.

So to cut a long story short I want to click a button, pass those ContactIDs to a sql query (or stored procedure), create a new excel spreadsheet, fill it with the query result and save it to the user's desktop.
Also a button to create an Outlook contact and fill the fields with the relevant data is what I need but I don't know how to write code to interact with the two applications. Any ideas will be greatly appreciated.

Into Page_Load() of your ASPNET page add
     Response.ContentType = "application/vnd.ms-excel" ;
when you want to output as EXcel document and browser (IE for sure) will take care of it


Thank you cpkilekofp and gelbert for your suggestions. I'll test those ideas out asap. Would you by chance know how to access Outlook components directly?

I would prefer not to use csv files to import as contact data. I don't want the user of my page to see the file being created when importing into outlook - I want to give the impression it imports directly.

How can I automate the creation of a csv file/ excel spreadsheet/ outlook contact. Write the data, then save/close?

My appologies for the persistent questions.
