c# - How to handle 'View not found' InvalidOperationException in asp.net mvc? -

-

I have an asp.net mvc 1.0 site that serves some content from 2 level hierarchy / category / article < / P>

When things work right for a view of the article and the scene is provided. However, when the URL meets the routing status, but the view is not present, the exception is raised so that I can not go into the operation of the controller.

Routing: 

  Routes.MapRoute ("paragraph", "{class} / {article}. Espx", new {controller = "microcontroller", action = " Paragraph "});

MyController verb: 

  public action paragraph (string category, string text) {string path = string.format ("~ / scene / {0} / {1} .aspx ", category, article); ViewResult vr = View (Path); Return VR; }

However, when the view is not found, the system. Resident Operation Exposure is generated that I can not hold in the controller action.

Exception Description: System.InvalidOperationException: The view '/ / views / my-category / my-article-with-long-name.aspx' or its master was not found. Searched at the following places: ~ / views / my-category / my-article-with-long-name.aspx

I get the error to Application_Error () Method global.asax.cs :

  1. Do not know how to redirect error view from there
  2. Wonder if there is a better The place where the exception has been raised.

    3. XD, Greg, I appreciate your answer. It helps to take advantage of a well-researched solution that everything I have to do is an override controller. Since I only have one controller, where I need to behave, I need to override only the uppercase in that controller.

    It is being said, my solution does not consider symptoms as a disease, and as you both suggest, it will be better to check the existence of the file before implementing it. See on the path.

    Here I have used the code to treat the symptoms :) 

      Protected Override On Option (Exception Consultant Filter Contains) {// Invalid Operation Exception is thrown If the path of the view can not be resolved by // calculation, if (filterContext.Exception invalid operation exception) {filterContext.ExceptionHandled = true; FilterContext.Result = View ("~ / visible / error / NotFound.aspx"); FilterContext.HttpContext.Response.StatusCode = 404; } Base.OnException (filterContext); }

    A problem that I could not resolve, is a way to display NotFound View in a clean way. This is usually used through the error controller NotFound Action. I had to hardcode the path for this. I can live with it, but I would like to know whether it is possible that HC Path.

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...
