Add column to an existing spotfire table from a C# data structure

I am working on a spotfire extension where data is extracted from a spotfire table, sent to a standalone R script, and the results added as a new column. I am having trouble adding a new column to the spotfire table. After a bit of searching, the only references to adding a column were to either add a CalculatedColumn from an existing column and an expression or to convert the data to a text file data source, (the link explains how to do it using python, How to create a data table on the fly in Spotfire via python.). Are these the only options, is there a better way to do it? Note that i am constrained to use Spotfire 6.5, C# and the R.Net environment, i can't use TERR or Iron Python scripts. Any help is appreciated.

How to export Sql Server Data to Excel File in C#

How can one read sql server data and write it to excel file in C#?
Do I need to use an external .Net library, or is it just OK using Visual Studio itself?
Any example and link will be well appreciated..
Note: Please send examples for Winforms, not asp.net

I would use some kind of OR-Mapper to read data from SQL such as
NHibernate
Entity Framework
Linq 2 SQL
For writing data to Excel you could bind hardly to any Excel Version by referencing the Excel Assemblies. The cleaner and more beautiful way is to use Open XML SDK for Office http://www.microsoft.com/download/en/details.aspx?id=5124

Follow the below article, this even provide the facility to export the data into many formats.

Fix length record and creating a file

I have to create a fix length record file using C#. I read the records from database and then after some business logic I would like to write some of the fields into a text file.
I researched this and some recommend using an XML to define the file, while others format the string and then write that into a file.
Is there a proper way to do this? I would like to keep this object oriented.
Thanks for any hints.

take a look at http://www.filehelpers.com/ to export the data to a fixed file format. you may also want to look at http://hibernatingrhinos.com/open-source/rhino-etl to create a process that runs the export for you. rhino.etl includes operations for FileHelpers.

You can use Jet to parse fixed length records in a text file. This is a decent overview that should be able to get you started:

In the past when i've done this, I pull the data out of SQL as a Char(Length) so that the padding is handled by SQL. This makes the C# pretty easy to put together. You can do this by casting or converting the data when you select it, or by creating a table that is the exact format of your file and inserting the data in there before pulling it out into C#.

Query to search on a keyword in the content of a PDF file with the ADO.NET Entity Framework

I work a project with ASP.NET MVC 2 (C#) using the ADO.NET Entity Framework.
My database contains the path of a PDF file. j'extrère the contents of the PDF file, and I put it in my table in a column of type ntex (SQL Server).
My problem is that I want to do a search by a keyword in the content of a PDF file.
I do not find the query (requète).

try something like
SELECT * FROM MYTABLE WHERE MYCOLUMN LIKE '%keyword2search%'
For more information on LIKE see http://technet.microsoft.com/en-us/library/ms179859.aspx
Also consider changing ntext because it is deprecated according to http://technet.microsoft.com/en-us/library/ms187993.aspx
