Membership.GetUser() Does not return same value

[dknapp]

I am trying to see if a person has logged in, but the examples that i find to do that do not work with the MySQLDirect .NET 2 provider. I am using version 3.55.20.0.

The example I am tring to use is this:

Code: Select all

If Membership.GetUser() IsNot Nothing Then
  lblDisplayName.Visible = True
  lblDisplayName.Text = "Something"
End If

When I try to use this code I get an error:

System.ArgumentNullException was unhandled by user code
Message="Value cannot be null.
Parameter name: username"
ParamName="username"
Source="CoreLab.MySql.Web"
StackTrace:

How would I use the MySQLDirect .NET 2 provider to check if a user has logged in?

Thanks,
