Retrieve images from DataBase and display them using BinaryWrite

To retreive the IMAGES from Database use the method BinaryWrite of the Response Object. Also we need to set the appropriate content type.

All we are doing is executing a sql statement and looping through all the records. We are displaying only the Image from the table, Person. Before dispalying the image, we first set the contentType. Then we write the image to' the browser using the method, BinaryWrite


Public Sub Page_Load(sender As Object, e As EventArgs)

Dim myConnection As New SqlConnection(ConfigurationSettings.AppSettings("ConnectionString"))
Dim myCommand As New SqlCommand("Select * from Person", myConnection)

Try
myConnection.Open()
Dim myDataReader as SqlDataReader
myDataReader = myCommand.ExecuteReader(CommandBehavior.CloseConnection)

Do While (myDataReader.Read())
Response.ContentType = myDataReader.Item("PersonImageType")
Response.BinaryWrite(myDataReader.Item("PersonImage"))
Loop

myConnection.Close()
Response.Write("Person info successfully retrieved!")
Catch SQLexc As SqlException
Response.Write("Read Failed : " & SQLexc.ToString())
End Try

End Sub
