Chapter 5: FILESTREAM with ASP.NET and SilverlightRunning the applicationRun the application again on your favorite web browser. Enter the item information,including the location of an image file to load into the FILESTREAM column, and clickSave to push the information to the database (Figure 5-20).Figure 5-20:Running the application.This time, the information should be successfully added into the database. You can verifythis by looking in the Items table; in SSMS, run a SELECT * from Items query on theItems table to see whether the newly entered data shows up in the table.Congratulations! You have successfully completed the second ASP.NET lab. It is time tomove on to the next lab and explore some more interesting stuff.188
Chapter 5: FILESTREAM with ASP.NET and SilverlightLab 6: Creating a Web Handler to Serve Imagesfrom a FILESTREAM DatabaseIn Lab 4, we saw how to upload files into the FILESTREAM column of a SQL Serverdatabase from a web page. In this lab, we will see how to serve those files back to theclient applications, upon request.We will create a web page to retrieve images from the database and send them to theclient browser. A web page is not the best way to implement such a handler, but at thisstage we want to minimize complexity, so that we can focus on FILESTREAM and noton ASP.NET features. In a later lab, we will develop a similar solution using a generichandler, which is a much better approach.To do this, we will:• create a stored procedure to retrieve the FILESTREAM information• create the web page that serves item images• run and test the application.Creating a stored procedure to retrieveFILESTREAM dataStart by creating a stored procedure that will retrieve the logical path name of theFILESTREAM value, and the FILESTREAM transaction context. This stored procedure,shown in Listing 5-9, will take an item number as input parameter and will return theFILESTREAM information.189
