c# - ASP.NET MVC Custom Error Handling Application_Error Global.asax? -

-

I have some basic code to define errors in my MVC application. Currently I have a error in my project Working methods with a controller called HTTPError404 () , HTTPError500 () , and normal . All those string parameters error accept or use the code given below What is the best / proper way to pass data to the error controller for processing? I would like to have a strong solution as possible. 

  Protected Zero application_Error (Object Sender, EventArgs E) {exception exception = Server.GetLastError (); Response.Clear (); Exception as HttpException httpException = HttpException; If (httpException! = Null) {Routed Data Routine = New Root Data (); RouteData.Values.Add ("Admin", "Error"); Switch (httpException.GetHttpCode ()) {case 404: // page path data not found. value. Add ("Action", "HTTPERR 404"); break; Case 500: // server error path data value. Add ("Action", "HTTPAR 500 500"); break; Default: route data value. Add ("verb", "normal"); break; } RouteData.Values.Add ("Error", exception); // clear error on server server Cleaner (); // How to correctly pass the root data to the error controller at this point? }}

Instead of creating a new route for that, you can only access your Controller / Pass the information through Action and QueryString. For example: 

  Secure Zero application_Error (Object Sender, EventArgs E) {exception exception = Server.GetLastError (); Response.Clear (); Exception as HttpException httpException = HttpException; If (httpException! = Null) {string action; Switch (httpException.GetHttpCode ()) {case 404: // page not found action = "HTTPERR 404"; break; Case 500: // server error action = "HTTPP 500 500"; break; Default: verb = "normal"; break; } // clear error on server server Cleaner (); Response.Redirect (String.Format ("~ / Error / {0} /? Message = {1}", Action, Exception Message.)); }

Then your controller will receive whatever you want: 

  // GET: / Error / HTTPRIR 404 Public Actionship HTTPPart 404 (string Message) {Return View (see "Some Views", Messages); }

There are some tradeoffs with your attitude Be careful with looping in this type of error handle. The second thing is that when you are going to handle a 404 through the ASP.NET pipeline, you will create a session object for all those hits. This can be a problem (performance) for heavily used systems.

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...
