I've been experiencing problems on some computers with XML Serialization. On
some computers the files do not get created on the web server's hard drive
and it's been driving me nuts trying to figure it out.

I store navigation history and application state in object collections and
save this upon application exit by doing an XML.Serialize.

I'd like to serialize directly to SQL Server instead. Can I create a stream
object to be used by SQL Server with serialization?

Thanks

Yeah, this is the basics (DT is just an object I'm taking from session and
serializing):

Dim ms As New MemoryStream
ms = SerializeDT(CType(Session("DT"), DTProcess))
Dim da() As Byte
da = ms.ToArray
cmd.Parameters("@DesktopData").Value = da
SqlConnection1.Open()
cmd.ExecuteNonQuery()
SqlConnection1.Close()

Public Shared Function SerializeDT(ByVal DTSource As DTProcess) As
MemoryStream
Dim ms As New MemoryStream
Dim formatter As New BinaryFormatter
formatter.Serialize(ms, DTSource)
ms.Position = 0
Return ms
End Function

thanks John.

I've never used binary objects in SQL before.

Where exactly is your data "@DesktopData" stored in the database? Do you
have a field already defined?

Cheers,

Yes, I have a field defined. The datatype is image, which is
variable-length binary data from 0 through 231-1 (2,147,483,647) bytes.
