[upperwall1]

Hi Gurus,
I've developed an application that uses plink. Its a window based application and now im trying to create the same application but in ASP.NET. The problem is I get an error when i try to put the instance of my class to a session. Please help me gurus...plsssssssssssssssssssssss

heres the part of my program.

Dim objSSH As classSSH
objSSH = New classSSH

        Dim sHostName As String
        Dim sUserName As String
        Dim sPassword As String
        sHostName = drpHostName.SelectedValue.Trim
        sUserName = txtUserName.Text
        sPassword = txtPassword.Text

        Dim sStatusLogin As String
        sStatusLogin = objSSH.sPuttyLogin(sHostName, "D:\plink.exe", Me.txtPassword.Text,     Me.txtUserName.Text)
        Session("ssh") = objSSH           'This is the line where error starts

the error is: Unable to serialize the session state. In 'StateServer' and 'SQLServer'
mode, ASP.NET will serialize the session state objects, and as a result
non-serializable objects or MarshalByRef objects are not permitted. The same
restriction applies if similar serialization is done by the custom session
state store in 'Custom' mode.
