Confusion on nothing
 

Hi

I am confused over how to check for nulls (Nothing in vb.net?). For instance
I am trying to create user in my vb.net/asp.net app as below;

Dim newUser As MembershipUser = Membership.CreateUser(Username, Password,
Email, passwordQuestion, passwordAnswer, True, status)
If (newUser = Nothing) Then

But I get an "Operator '=' is not defined for types
'System.Web.Security.MembershipUser' and
'System.Web.Security.MembershipUser'. " error on the second line above. What
is the correct method to check for nothing in vb.net?

Thanks

Regards

Use the "Is" operator
If (newUser is Nothing) Then

or the related (VS2005)
If (newUser isNot Nothing) Then

Re: Confusion on nothing
 

use the "is" keyword in vb.net

if user is nothing then
