asp.net - Session Expires and User is no longer valid -


I cache information about the currently logged in user in session. Whenever the CurrentUser property is used on my global application class, this information is loaded, it calls GetUser () on my custom implementation of the subscription provider, which loads the user from the session. , Or loads the user with DB and throws the user object into the session.

How should I handle this scenario?

  1. User login.
  2. Deletes the user administrator (or disables ... the issue is that they can not enter any more)
  3. The user's session is ending < / Li>
  4. Users navigate or request a page, or whatever.

At present, if this scenario comes, NullReferenceExceptions are thrown everywhere, because ASP.NET Framework Call GetUser () does not give anything because it does not allow the user in the database Can not find (and nothing is in the session because it is finished).

If your app thinks that a user is signed in, but the user can not be found, then one The option FormsAuthentication.SignOut () may be used to forget about ASP.NET users, then they should be brought back to the long screen or the anonymous mode.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors?

Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
