Question

I am creating a small application where i am reading am image from the database, storing the image in a file, and then setting the Image Control ImageURL property to the created file

The code is pretty straight forward

Dim m_Bytes As Byte() = DirectCast(command.ExecuteScalar, Byte())

    Dim strfn As String = "D:\" + Convert.ToString(DateTime.Now.ToFileTime()) + ".jpeg"

    Dim fs As New FileStream(strfn, FileMode.CreateNew, FileAccess.Write)

    fs.Write(m_Bytes, 0, m_Bytes.Length)
    fs.Flush()
    fs.Close()

    Image1.ImageUrl = strfn

The image is getting created properly at the location but the image control does not render an image . I checked the source of the page and the image control was pointing to

 <img id="Image1" src="D:\129901061171254403.jpeg" />

The src is pointing to the correct location…

Thanks in Advance….

You must store the image in a location that is accessible under IIS.

You could for instance have a folder under you application where you store the image. Let’s say your application is deployed in the folder d:\virtualDirs\myApp and you browse it on the url http://someserver.com/superapp/.

You could then store the image in (for instance) the folder d:\virtualDirs\myApp\dynImages:

d:\virtualDirs\myApp\dynImages\129901061171254403.jpeg

and then set the ImageUrl:

Image1.ImageUrl = "~/dynImages/129901061171254403.jpeg";

Sending the local folder path in the webpage simply wont work since that is where the file is on the server.
