Retrieve & display image from sql database in vb.net


In my previous post I have discuss about how to store image into sql server database using vb.net.
It is time to fetch image from sql server database and display into picture box. Here is the snapshot of vb.net code.
First of all we have to imports these namespace in our class.

Imports System.IO
Imports System.IO.Stream
Public Function getImagefromByte(ByVal data As Byte()) As Image
        Dim ms As MemoryStream = New MemoryStream()
        Dim img As Image
        Try
            ms.Write(data, 0, data.GetUpperBound(0))
            img = Image.FromStream(ms)
        Catch ex As Exception
            img = My.Resources.noimage
        Finally
            'ms.Close()
            'ms = Nothing
        End Try
        getImagefromByte = img
    End Function

Here is code that show how to call this function and display image into picture box. ds is object of DataSet class and DataAdaptor is used fill that dataset, ”photo” field type in sql database is image.
pic is PictureBox control.

        Dim data() As Byte
        data = CType(ds.Tables(0).Rows(0)("photo"), Byte())
        pic.Image = getImagefromByte(data)


this will fetch picture from sql database and display into  picture box.
