Thanks in advance.

I have an objuct that I declared like this:
Class DailyStats Dim _day As String Dim _hour As String Dim _impressions As String Dim _clicks As String Property Day() As String Get Return _day End Get Set(ByVal value As String) _day = value End Set End Property Property Hour() As String Get Return _hour
What is the proper way to check for null or empty strings on dynamic objects? This is the only solution I've found so far:
if (admin.PasswordHash.GetType() == typeof(DBNull) || admin.PasswordHash == string.Empty)
If the field is null, the object returned is DBNull.Value, but if the field is empty string, it's return as a System.String object. This makes it impossible to do regular "admin.PasswordHash == DBNull.Value" check, as that will fail whenever the field has been set to empty string. Is my example the right (and only) way to go?
Is there any way or process to serialize the the objects?? i am trying to store the instance of few control in viewstate but it shows error msg that it is not a serialized object. should i perform some steps to serialize the objects ???

I have a second class named "Class2" Class2, is a member of class 1,and is implemented as an array of objects of type Class 2.
If I try and call the Accessor GetName() my hard coded value "Hello" in my accessor is not returned? Onlyan alpha character like "T"
Also if I try and assigne a value using the setter GetName() it does not work, and the compiler gives me an error message "property Chars is ReadOnly? Does anyone know what is wrong in my code? Line 6 above

The .NET Framework 4 introduces some new features that enable you to go beyond static types. We explore dynamically expando objects and demonstrate how they can be used like dynamically updatable dictionary objects.

Until now, Microsoft did not provide explicit support in the .NET Framework for manipulating security settings. With the .NET Framework 1.x, access can only be granted to users via a series of cumbersome P/Invoke calls. By introducing the concepts of security objects and rules, the .NET Framework 2.0 allows developers to manipulate security settings of objects in a few easy steps using managed code. Want to know more? Read on.
