authorization - ASP.net MVC: Getting Required Roles for Login? -

-

Is there a general way to obtain the required role for a particular action?

My problem with detail is that I have 2 roles such as "Users" and "Admin" and an action with:

[Authorize (roles = "admin" )] Admin of Public Sector Administration ...

If the user is not logged in, he takes the login screen. Okay. When a user logs in to the role of "Admin", then all works well, but if the user logs in with "role" then he will display the login screen continuously, in addition he has successfully entered, but definitely Does not have the necessary role.

So it would be good if the login display can show an alert, saying that it is already logged in, but it does not have the necessary rights to view this page. And additionally it can display the necessary roles.

Thank you, Michael

I think this is mainly the default AuthorizeAttribute From the design page, if fails in any part of the authorization.

You can create a new class that is AuthorizeAttribute . Then you can override the default behavior and show a different page. See for a great example of this.

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
