The first few lines of code merely set properties of the OpenFileDialog object.
In the btnBrowse_Click event handler, you can see how this is done. To do this, use an OpenFileDialog object in conjunction with a standard Button control. The first task is to find an image on your hard disk.
The name of database file is Images_Data.

I have included the database file in the zip file that you can attach in SQL Server databases. Note:This Database should be in SQLS erver. The data Type of the Name field is ( nVarChar) and data type of Picture is ( Image) in Sql Server 2000. The first step you have to do is to create a Database table name it Pic, which should contain the two, fields 1: Name 2: Picture. Once the image is converted to a byte array, it’s saved to a database by using coding. Stream classes allow you to work with binary data, reading and writing back and forth between streams and data structures ( such as a byte array). NET is essentially an abstraction of a sequence of bytes, whether these bytes came from a file, a TCP/IP socket, a database, or wherever. One of the easiest ways is to use a concrete implementation of the Stream class. Thus, the main question is: How does one convert an image file-whether a JPEG, Bitmap, or other format-into an array of bytes? There are several ways to accomplish this in. Rather, the Image data type can store anything as variable-length binary data.Ī byte array is used to send data to an Image field. Be sure not to confuse the Image data type with the word image, as if to imply that only images can be stored therein. The new concepts in this article center around the abstract Stream class and how it’s used to convert an image file to and from the Image data type that SQL Server uses to store images.

This sample application will show you how to build a Windows Forms interface that allows you to do the following: Sometimes you need to store images in a database instead of as physical files.
