Save an image displayed in the Picture. Box control to the database. Select an image from a List. Box control, and load it from the database. New Concepts. The new concepts in this article center around the abstract Stream class and how its used to convert an image file to and from the Image data type that SQL Server uses to store images. Be sure not to confuse the Image data type with the word image, as if to imply that only images can be stored therein.

A nocost, streamlined, easytouse development tool for hobbyists, students, and novices. Rather, the Image data type can store anything as variable length binary data. A byte array is used to send data to an Image field. Thus, the main question is How does one convert an image filewhether a JPEG, Bitmap, or other formatinto an array of bytes There are several ways to accomplish this in. NET. One of the easiest ways is to use a concrete implementation of the Stream class. A stream in. NET is essentially an abstraction of a sequence of bytes, whether these bytes came from a file, a TCPIP socket, a database, or wherever. 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. Once the image is converted to a byte array, its saved to a database by using coding. Creating Database. 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. The data Type of the Name field is n. In the Fifth Edition, Advanced Visual Basic 2010 helps those who are familiar with the fundamentals of Visual Basic 2010 programming harness its power for. Architecture. Visual Studio does not support any programming language, solution or tool intrinsically instead, it allows the plugging of functionality coded as a. Creating PDF documents in Visual Basic has always been a difficult task. Many times people have to purchase controls to do it for them. Not with this Visual Basic. Oracle acquired Sun Microsystems in 2010, and since that time Oracles hardware and software engineers have worked sidebyside to build fully integrated systems and. PDF files that contain the Visual Studio 2005 documentation. Var. Char and data type of Picture is Image in Sql Server 2. Note This Database should be in SQLS erver. I have included the database file in the zip file that you can attach in SQL Server databases. The name of database file is ImagesData. Browsing for and Displaying an Image. The first task is to find an image on your hard disk. To do this, use an Open. File. Dialog object in conjunction with a standard Button control. In the btn. BrowseClick event handler, you can see how this is done. The first few lines of code merely set properties of the Open. File. Dialog object. With Open. File. Dialog. Initial. Directory C. Filter All Files. Bitmaps GIFs gifJPEGs Filter. Index 2. A pipe delimited pair of file types is provided to determine the valid file types that can be accessed through the dialog box. Among other properties, you can also set Filter. Index to the default file type that you want to appear in the dialog boxs Files Of Type menu. The index is not zero based, so in this example, Bitmaps will appear as the default. The dialog box is not actually opened until its Show. Dialogmethod is called, which can be combined in an IfThen statement to check which button was pressed and perform follow on tasks If Open. File. Dialog. 1. Show. Dialog Dialog. Result. OK Then.

String. Although an Open. File. Dialog object contains an Open button instead of an OK button, there is no Dialog. Result enumeration for the Open button. Instead, use the OK enumeration. Once its confirmed that the Open button has been clicked, properties of the Picture. Box control are set. Notice how the Image propertywhich requires an object of type System. Drawing. Imageis assigned. The Image class is abstract and exposes a number of shared methods for working with images, one of which is From. File. This method creates an Image object from a fully qualified path although the Open. File. Dialog. File. Name property might lead you to think that it contains only the file name, it actually has the full path. Now that your image file is represented by an Imageobject, you can use a stream to convert it to a byte array. In the btn. SaveClick event handler, the first line of code creates a Memory. Stream object Dim ms As New Memory. StreamA Memory. Stream object is simply a stream that uses memory as its backup store instead of some other medium. As a result, a Memory. Stream object usually provides better performance. Streams are flexible. You could, for example, have used a File. Stream object to open the image file directly and read it in. There are certainly numerous other ways, too. The implementation here, however, is simple and straightforward. The Memory. Stream is then passed as an argument to the Save method, another member of the Image class. You can optionally pass the image formatfor example, by accessing the Images read only Raw. Format property pic. Save. Image. Savems, pic. Save. Image. Raw. FormatThe actual byte array conversion comes in the next line. Get. Buffer returns an array of unsigned bytes being held by the stream. Dim arr. Image As Byte ms. Get. Buffer. ms. Close It is good to always close the stream rather than. The last data gathering task is to extract the filename from the full path there is no need to store the entire path in the database Dim str. Filename As String. File. Path. Text. Substringlbl. File. Path. Text. Last. Index. Of1. This might look a bit complex and convoluted, but all youre doing is indicating that you want a substring of the full path that starts after the last backslash. With the filename extracted and the image converted to a byte array, youre now ready to use the ADO. NET practices youve already learned to push these to the database. Dim cnn As New Sql.

As you can see, at this point there is nothing new except the use of the Sql. Db. Type. Image enumeration. Set the value of the Picture parameter to the byte array, and execute the INSERT statement as you would with any other type of data. Reading an image. From this point forward, youre essentially reversing the process. To display an image, you have to convert it from a byte array to an Image, and then assign it to the Picture.
