From: Mr. X. on 16 Jun 2010 07:56 Hello. Is there any way to save a control + all of it's components to a file (or give it some representation as a long string). Thanks :)

From: Mr. X. on 20 Jun 2010 03:22 I would like to learn more about serialization. The code I did is : Dim f As System.IO.FileStream Dim binFormat As New BinaryFormatter f = nothing try f = New FileStream("items.txt", FileMode.Create) binFormat.Serialize(f, MyPanel) finally f.close() end try MyPanel is declared as Panel. (dim myPanel as Panel ...) Even I create myPanel as this : Public Class MyPanelClass Inherits Panel Implements ISerializable Public Sub GetObjectData(ByVal info As System.Runtime.Serialization.SerializationInfo, ByVal context As System.Runtime.Serialization.StreamingContext) Implements System.Runtime.Serialization.ISerializable.GetObjectData Dim i As Integer i = 1 ' this code is not reachable **** what should I write here. need an example, please *********************** End Sub End Class .... dim myPanel as MyPanelClass .... I need a simple sample (specifically : saving panel & objects on it).
