hi,
I have a aspx page that is binded to Master Page with content.

in some cases the user has signed in to asp.net membership and I have login view in the master page.

Otherwise they are not signed in but when they visit a page where the page load is coded below I get
an exception.

protected void Page_Load(object sender, EventArgs e)     {
   Guid userid = (Guid)Membership.GetUser().ProviderUserKey;         if (CheckUsername(userid) == true)         {             Label10.Visible = true;         }         else         {       &nbs ...

Go to the complete details ...
