NullReferenceException in Profile

[Saber]

in <system.web> of web.config I've:
[...]
<profile>
<properties>
<add name="EnterTime" type="System.DateTime" allowAnonymous="true"/>
</properties>
</profile>

And in Session_Start of global.asax:
[...]
Profile.EnterTime = System.DateTime.Now '**** Line 26

But I get an error message in line 26:
System.NullReferenceException was unhandled by user code
Message="Object reference not set to an instance of an object."

Thanks Eliyahu,
I used your syntax:
Dim EnterTime As String = System.DateTime.Now.ToString
HttpContext.Current.Profile.GetPropertyValue(EnterTime)

but again the same error, here is the error details:
System.NullReferenceException was unhandled by user code
Message="Object reference not set to an instance of an object."
Source="App_global.asax.5_wxyugz"

The syntax you are using is good for an aspx file for a page. In
global.asax Profile is not defined . You can access it via
HttpContext.Current with syntax:

HttpContext.Current.Profile.GetPropertyValue("EnterTime");

There is no difference in C# and VB syntax in this case (except the
semicolon of end of line!),
Thank you for showing me the right way, I've to use *SetPropertyValue*
because I'm writing
a value not reading.

VB:
Dim EnterTime As String = System.DateTime.Now.ToString
HttpContext.Current.Profile.SetPropertyValue("EnterTime", EnterTime)

C#:
string EnterTime = System.DateTime.Now.ToString();
HttpContext.Current.Profile.SetPropertyValue("EnterTime", EnterTime);

BUT again the same error message(NullReferenceException)

I am not good in VB.

In GetPropertyValue(EnterTime) EnterTime should a string constant. In c# I
would write GetPropertyValue("EnterTime").

What can make a NullReferenceException when trying to read/write a Profile
value?
I configured the database using aspnet_regsql.exe wizard.
How to test it configured properly?
