I’m using different objects in my .vb file. Here is the code.
Dim currentdate As DateTime
Dim myForm As Control = Page.FindControl("Tips_Tricks")
DBNull.Value

I’m getting compilation error (Type 'DateTime' is not defined)for all these above statements. I’m sure some namespace need to be imported inside the page. Can any one tell me which are these namespaces.
Also suggest some good reference guide for using namespaces.

DateTime and DBNull is in the System namespace.
Control is in the System.Web.UI namespace

Not sure why you would be getting errors. Are you using VS.NET, and if so, is the System namespace in the references list in the solution explorer? I thought by default it is.
