iis 7 - asp.net mvc keeps overriding text/html content-type with .wml -

-

I am developing a website that is being viewed on mobile (cellphone) devices. I'm just using plain HTML 4.01, not very special. Except Nokia Series 40 1-5 versions, we have presented pages properly on all mobile browsers. On closer inspection, it seems that the IIS is automatically rendering html with the content-type of text / vnd.wap.wml instead of text / html . Since we are not using WAP, the page fails with error.

I am using ASP.Net MVC 1.0, so I've added a ActionFilterAttribute to override content-type. This code runs but the client still comes out as vnd.wap.wml.
I am using this principle;

& lt ;? XML version = "1.0" encoding = "UTF-8"? & Gt; & Lt ;! DOCTYPE HTML PUBLIC "- // W3C / / DTD HTML 4.01 Transitional // N" "http://www.w3.org/TR/html4/loose.dtd" & gt;

It is worth noting that vnd.wap.wml first is worth Accept-Encoding specified by mobile browser, so I IIS7, so this offer Let's take it. And I think MVC does not specifically mention .html (or .aspx) files, maybe the mime-type is being skipped? I suppose it's probably an IIS fine rather than a code properly.

Any help is greatly appreciated!

Turns out I ActionFilter was not implemented correctly .. I OnResultExecuted than OnActionExecuted method Need to override the method. The full feature looks like this (add the [HtmlOverrideFilter] to your controllers where necessary. Hopefully this does help someone 

  inner class HtmlOverrideFilter: ActionFilterAttribute {public override void OnActionExecuted (ActionExecutedContext filterContext) {filterContext.HttpContext.Response.ContentType = "text / html"; } Public override void OnResultExecuted (ResultExecutedContext filterContext) {filterContext.HttpContext.Response.ContentType = "text / html"; }}

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...
