i *think* what's happening is you are writing the stream out correctly,
but as a binary stream, not as an image so when you come to open it, the
system doesn't handle it properly.
anyway i think the following would work...this is untested, so don't
blame me if the machine dies a painful death! ;>
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs)
Handles MyBase.Load
' Declare variables
Dim oDly As New com.esynaps.www.DailyDilbert()
Dim oByte() As Byte
' This is the call to the web service
oByte = oDly.DailyDilbertImage()
'display it on website
Response.BinaryWrite(oByte)
'save gif to hd
dim strmMem as MemoryStream = new MemoryStream(oByte)
dim dilbertPic as Image = new Bitmap(strmMem)
dilbertPic.Save("c:\temp\dailydilbert.gif")
strmMem.Close()
End Sub
make sure that the asp.net process has permission to write to the
directory as well.
hope that works,
