Introduction

Most of the time when developing web applications/projects we find the need to display images on the ASP.NET pages. This can include customer pictures, avatars, location maps or other binary data. One good way of doing this is to have a dummy page called, which writes out the binary data using the Response.BinaryWrite() as explained in this article. This article explains using an HttpHandler to display the images.

I have an image saved into a MSSQL Server as varbinary(MAX). How do I get this image and execute it using a handler?

I have found some code here:
[code]
Public Sub getImage()
Dim connectionString As String
Dim connection As SqlConnection
Dim adapter As New SqlDataAdapter
connectionString = "*******"
Dim UserId As String = System.Web.Security.Membership.GetUser().ProviderUserKey.ToString
connection = New SqlConnection(connectionString)

Dim command As New SqlCommand("SELECT Img1 FROM Nomogram WHERE bID=133", connection)
connection.Open()
Dim pictureData As Byte() = DirectCast(command.ExecuteScalar(), Byte())
connection.Close()
Dim picture As Image = Nothing
'Create a stream in memory containing the bytes that comprise the image.
Using stream As New IO.MemoryStream(pictureData)
'Read the stream and create an Image object from the data.
picture = Image.FromStream(stream)
End Using
End Sub
[/CODE]

Any idead on how to display it`?
Kind regards Hans Peter

My bad: I'd put the xsd and xss files in the app_data folder.

Excellent example!

Yes, you could do that and the content-type was the "key" to that. I'm writing on that and will be available in a couple of days.

Thanks

Could you use this same sort of set up to pull things like .doc or .pdf files that might be stored in a database?
