asp.net - How to force ASMX web service to send JSON data to client on HTTP GET request? -

-

I am trying to use official with ASMX web service in ASPNT 3.5 web form application. If I understand it correctly, then the auto-complete plugin can use HTTP GET to call only one service (with two query string parameters: q and range ). I came to know how the Web service responds to the HTTP GET call, but I did not know how this can return JSON data (even if the service calls it using JS $ $ data.), When calling from the complete plugin, it always gives XML). Here are some code snippets:

Web service: 

  [ScriptService] [WebServices (namespace = "http://tempuri.org/")] Public class UserWS: WebService {[WebMethod] [ScriptMethod (Use HTTPPat = true, response format = response format. Jason)] Public list & amp; YouTube Dislike Menu & gt; GetUnivers (string q, int limit) {list & lt; UserDisplayInfo & gt; User = GetUsers (Q, Border); Return users. }}

Web page: 

  $ ("# test"). Autocomplete ("./services/UserWS.asmx/GetUsers", {dataType: 'Jason', type: 'POST', // This setting is ignored by the content type: 'application / json; charset = utf- 8 ', pars: function (data) {// ...}});

If this is not possible, then I wonder what would be a better option:

  • Using HTTP POST and JSON data instead of GTE and query Fix the auto-complete plugin for string parameters;
  • Using a different autoplayplate plugin (I looked at something, but this time the official plugin has the most recommendations, and I'm not sure other plugins support HTTP posts);
  • An alternative to the ASMX web service, such as WCF Web Services (I would not like to use WCF because the ASMX web service is easy to implement - no web configured change, no contract, no Not the interface - and it gives me everything I need);
  • Something else

I got many similar questions on the stack overflow, but I did not find the answer to the answer that would work for me any (good) idea?

Autocomplete plugin should result in plain text format, not JSON. Each item should be on a separate row: 

  foo \ n times \ nbaz \ n

with the generic handler (.sx) web service Try changing: 

  Public class MyHandler: IHttpHandler {public void ProcessRequest (HttpContext reference) {context.Response.ContentType = "text / plain"; Context.Response.Write ("foo \ Nbar \ nbaz"); } Public Child IRUUL (see {return incorrect;}}}

See if you want ASMX web service to return JSN, you can not use GET. / P>

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...

I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image.

Another option is to use and load the image.

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...
