Uploading Files VB Microsoft Docsby Scott Mitchell. Download Sample App or Download PDFLearn how to allow users to upload binary files such as Word or PDF documents to your Web site where they may be stored in either the servers file system or the database. Introduction. All of the tutorials we ve examined so far have worked exclusively with text data.

An online dating site might allow users to upload a picture to associate with their profile. A recruiting website might let users upload their resume as a Microsoft Word or PDF document. Working with binary data adds a new set of challenges. We must decide how the binary data is stored in the application. The interface used for inserting new records has to be updated to allow the user to upload a file from their computer and extra steps must be taken to display or provide a means for downloading a record s associated binary data. In this tutorial and the next three well explore how to hurdle these challenges. At the end of these tutorials well have built a fully functional application that associates a picture and PDF brochure with each category. In this particular tutorial well look at different techniques for storing binary data and explore how to enable users to upload a file from their computer and have it saved on the web server s file system.

Step 1 Creating the Working with Binary Data Web Pages. Before we begin to explore the challenges associated with adding support for binary data, let s first take a moment to create the ASP. NET pages in our website project that well need for this tutorial and the next three. Start by adding a new folder named Binary. Data. Next, add the following ASP.

Figure 3 The Site Map Now Includes Entries for the Working with Binary Data Tutorials. Step 2 Deciding Where to Store the Binary Data. Binary data that is associated with the application s data model can be stored in one of two places on the web server s file system with a reference to the file stored in the database or directly within the database itself see Figure 4. Each approach has its own set of pros and cons and merits a more detailed discussion. Figure 4 Binary Data Can Be Stored On the File System or Directly in the Database Click to view full size imageImagine that we wanted to extend the Northwind database to associate a picture with each product. One option would be to store these image files on the web server s file system and record the path in the Products table. With this approach, we d add an Image. Path column to the Products table of type varchar2. When a user uploaded a picture for Chai, that picture might be stored on the web server s file system at ImagesTea. Phtls 7 Edicao Em Pdf on this page. That is, if the web site is rooted at the physical path C WebsitesNorthwind, ImagesTea. C WebsitesNorthwindImagesTea. After uploading the image file, we d update the Chai record in the Products table so that its Image. Path column referenced the path of the new image. We could use ImagesTea. Tea. jpg if we decided that all product images would be placed in the application s Images folder. The main advantages of storing the binary data on the file system are Ease of implementation as well see shortly, storing and retrieving binary data stored directly within the database involves a bit more code than when working with data through the file system. Additionally, in order for a user to view or download binary data they must be presented with a URL to that data. If the data resides on the web server s file system, the URL is straightforward. If the data is stored in the database, however, a web page needs to be created that will retrieve and return the data from the database. Wider access to the binary data the binary data may need to be accessible to other services or applications, ones that cannot pull the data from the database. For example, the images associated with each product might also need to be available to users through FTP, in which case we d want to store the binary data on the file system. Performance if the binary data is stored on the file system, the demand and network congestion between the database server and web server will be less than if the binary data is stored directly within the database. The main disadvantage of storing binary data on the file system is that it decouples the data from the database. If a record is deleted from the Products table, the associated file on the web server s file system is not automatically deleted. We must write extra code to delete the file or the file system will become cluttered with unused, orphaned files. Furthermore, when backing up the database, we must make sure to make backups of the associated binary data on the file system, as well. Moving the database to another site or server poses similar challenges. Alternatively, binary data can be stored directly in a Microsoft SQL Server 2. Like with other variable length data types, you can specify a maximum length of the binary data that can be held in this column. For example, to reserve at most 5,0. MAX allows for the maximum storage size, about 2 GB. The main advantage of storing binary data directly in the database is the tight coupling between the binary data and the database record. This greatly simplifies database administration tasks, like backups or moving the database to a different site or server. Also, deleting a record automatically deletes the corresponding binary data. There are also more subtle benefits of storing the binary data in the database. Software Free Download Augesoft. Recommended Downloads. New Updated Software.
