Since upgrading to Visual Studio 2003 and using the .Net framework v1.1 I am recieving an error while trying to use the examples found in chapter 5 with events.
Additional information: Type System.DelegateSerializationHolder and the types derived from it (such as System.DelegateSerializationHolder) are not permitted to be deserialized at this security level.
Code:
Public Sub Run()
Dim strURL As String
Dim myConference As Conference.Conference
Dim contribution As String
Dim name As String
Dim nickName As String
strURL = "tcp://localhost:8086/MyConference.rem"
myConference = CType(Activator.GetObject( _
GetType(Conference.Conference), _
strURL), Conference.Conference)
AddHandler myConference.TheDelegate, AddressOf ExternalCallback
While True
Console.Write("Input? ")
contribution = Console.ReadLine()
If contribution.Length = 0 Then
Exit While
End If
myConference.Input(contribution)
End While
RemoveHandler myConference.TheDelegate, AddressOf ExternalCallback
End Sub
The error occurs when trying to add the handler.
Any help on this subject would be greatly appreaciated.
Thank you,
Christopher P. Cooper
