  • Program crashes after trying to use a recently created file. C#

    - by Jason T.
    So here is my code if (!File.Exists(pathName)) { File.Create(pathName); } StreamWriter outputFile = new StreamWriter(pathName,true); But whenever I run the program the first time the path with file gets created. However once I get to the StreamWriter line my program crashes because it says my fie is in use by another process. Is there something I'm missing between the File.Create and the StreamWriter statements?

    - by user576611
    Hi Everyone, I'm specifically using the Google Contacts API at the moment, but this could be true of other scinarios as well. I have the following code: Contact newContact = new Contact(); When I let the code run without any breakpoints, I get a NullReferenceException on all of the properties of this object. However, if I put a breakpoint just after this line, I can see all of the properties have been initialises and the rest of my code executes fine. Any idea's would be greatly appreciated

  • Is there an equivalent to RSpec's before(:all) in MiniTest?

    - by bergyman
    Since it now seems to have replaced TestUnit in 1.9.1, I can't seem to find an equivalent to this. There ARE times when you really just want a method to run once for the suite of tests. For now I've resorted to some lovely hackery along the lines of: Class ParseStandardWindTest < MiniTest::Unit::TestCase @@reader ||= PolicyDataReader.new(Time.now) @@data ||= @@reader.parse def test_stuff transaction = @@data[:transaction] assert true, transaction end end

Thx

  • How do I send a javascript variable to a subsequent jquery function or set of braces?

    - by desbest
    How do I send a javascript variable to a subsequent jquery function? Here is my code. <script type="text/javascript"> $(function() { var name = $("#name"), email = $("#email"), password = $("#password"), itemid = $("#itemid"), tips = $(".validateTips"); function updateTips(t) { tips .text(t) .addClass('ui-state-highlight'); setTimeout(function() { tips.removeClass('ui-state-highlight', 1500); }, 500); } $("#dialog-form").dialog({ autoOpen: false, height: 320, width: 350, modal: true, /* buttons: { 'Change category': function() { alert("The itemid2 is "+itemid2); var bValid = true; $('#users tbody').append('<tr>' + '<td>' + name.val() + '</td>' + '<td>' + email.val() + '</td>' + '<td>' + password.val() + '</td>' + '<td>' + itemid.val() + '</td>' + '</tr>'); $(this).dialog('close'); }, Cancel: function() { $(this).dialog('close'); } }, */ close: function() { allFields.val('').removeClass('ui-state-error'); } }); $('.changecategory') .button() .click(function() { var categoryid = $(this).attr("categoryid"); var itemid = $(this).attr("itemid"); var itemid2 = $(this).attr("itemid"); var itemtitle = $(this).attr("itemtitle"); var parenttag = $(this).parent().get(0).tagName; var removediv = "itemid_" +itemid; alert("The itemid is "+itemid); $('#dialog-form').dialog('open'); }); }); </script> I'll break it down. The .changecategory section happens FIRST when an image on my page is clicked. $("#dialog-form").dialog({ is then called, and the variable item id is not passed to this function. How can I pass a variable from one function to another? Is that possible. Is there a way I can pass a variable to another jquery function without having to resort of setting a cookie with javascript and then using jquery to read it?

  • Writing a mini-language with haskell, trouble with "while" statements and blocks { }

    - by Nibirue
    EDIT: problem partially solved, skip to the bottom for update. I'm writing a small language using haskell, and I've made a lot of progress, but I am having trouble implementing statements that use blocks, like "{ ... }". I've implemented support for If statements like so in my parser file: stmt = skip +++ ifstmt +++ assignment +++ whilestmt ifstmt = symbol "if" >> parens expr >>= \c -> stmt >>= \t -> symbol "else" >> stmt >>= \e -> return $ If c t e whilestmt = symbol "while" >> parens expr >>= \c -> symbol "\n" >> symbol "{" >> stmt >>= \t -> symbol "}" >> return $ While c t expr = composite +++ atomic And in the Syntax file: class PP a where pp :: Int -> a -> String instance PP Stmt where pp ind (If c t e) = indent ind ++ "if (" ++ show c ++ ") \n" ++ pp (ind + 2) t ++ indent ind ++ "else\n" ++ pp (ind + 2) e pp ind (While c t) = indent ind ++ "while (" ++ show c ++") \n" ++ "{" ++ pp (ind + 2) t ++ "}" ++ indent ind Something is wrong with the while statement, and I don't understand what. The logic seems correct, but when I run the code I get the following error: EDIT: Fixed the first problem based on the first reply, now it is not recognizing my while statment which I assume comes from this: exec :: Env -> Stmt -> Env exec env (If c t e) = exec env ( if eval env c == BoolLit True then t else e ) exec env (While c t) = exec env ( if eval env c == BoolLit True then t ) The file being read from looks like this: x = 1; c = 0; if (x < 2) c = c + 1; else ; -- SEPARATE FILES FOR EACH x = 1; c = 1; while (x < 10) { c = c * x; x = x + 1; } c I've tried to understand the error report but nothing I've tried solves the problem.

  • Javascript problem with a global external link confirmation alert

    - by OverDrive
    Below is the code from a plugin for Joomla. It works on it's own and it's purpose is to detect external links on the page and force them into new browser windows using _blank. I've tried for about an hour (I don't know javascript well) but I can't seem to figure out how to get an onclick function working. End result, I want to add to this script the ability of a confirmation dialog, shown in the 2nd code section. An external link, when clicked, will pop up the confirmation dialog, and if it says yes, they will be able to get to the external URL, opening in a new window. Otherwise, it cancels, and does nothing. When I create a link with onclick="return ExitNotice(this.href);" within it it works perfectly, but since my website has multiple people submitting input, I'd like the confirmation box global. this.blankwin = function(){ var hostname = window.location.hostname; hostname = hostname.replace("www.","").toLowerCase(); var a = document.getElementsByTagName("a"); this.check = function(obj){ var href = obj.href.toLowerCase(); return (href.indexOf("http://")!=-1 && href.indexOf(hostname)==-1) ? true : false; }; this.set = function(obj){ obj.target = "_blank"; obj.className = "blank"; }; for (var i=0;i<a.length;i++){ if(check(a[i])) set(a[i]); }; }; this.addEvent = function(obj,type,fn){ if(obj.attachEvent){ obj['e'+type+fn] = fn; obj[type+fn] = function(){obj['e'+type+fn](window.event );} obj.attachEvent('on'+type, obj[type+fn]); } else { obj.addEventListener(type,fn,false); }; }; addEvent(window,"load",blankwin); Second Part /* ---------- OnClick External Link Notice ---------- */ function ExitNotice(link,site,ltext) { if(confirm("-----------------------------------------------------------------------\n\n" + "You're leaving the HelpingTeens.org website. HelpingTeens.org\ndoes not " + "control this site and its privacy policies may differ\nfrom our own. " + "Thank you for using our site.\n\nYou will now access the following link:\n" + "\n" + link + "\n\nPress \'OK\' to proceed, or press \'Cancel\' to remain here." + "\n\n-----------------------------------------------------------------------")) { return true; } history.go(0); return false; } A) Can anyone help me fix this problem? or B) Is there a better solution?

  • Jetty servlet respons to Ajax always empty

    - by chris
    Hi I try to run a java server on Jetty which should respond to an ajax call. Unfortunately the response seems to be empty when I call it with ajax. When I call http://localhost:8081/?id=something I get an answer. The Java Server: public class Answer extends AbstractHandler { public void handle(String target, Request baseRequest, HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException { String id = request.getParameter("id"); response.setContentType("text/xml"); response.setHeader("Cache-Control", "no-cache"); response.setContentLength(19+id.length()); response.setStatus(HttpServletResponse.SC_OK); response.getWriter().write("<message>"+id+"</message>"); //response.setContentType("text/html;charset=utf-8"); response.flushBuffer(); baseRequest.setHandled(true); } public static void main(String[] args) throws Exception { Server server = new Server(8081); server.setHandler(new Answer()); server.start(); server.join(); } } The js and html: <html> <head> <script> var req; function validate() { var idField = document.getElementById("userid"); var url = "validate?id=" + encodeURIComponent(idField.value); if (typeof XMLHttpRequest != "undefined") { req = new XMLHttpRequest(); } else if (window.ActiveXObject) { req = new ActiveXObject("Microsoft.XMLHTTP"); } req.open("GET", "http://localhost:8081?id=fd", true); req.onreadystatechange = callback; req.send(null); } function callback() { if (req.readyState == 4) { if (req.status == 200) { var message = req.responseXML.getElementsByTagName("message")[0]; document.getElementById("userid").innerHTML = "message.childNodes[0].nodeValue"; } } } </script> </head> <body onload="validate('foobar')"> <div id="userid">hannak</div> </body> </html> I'm actually don't know what I'm doing wrong here. Maybe someone has a good idea. greetings chris

  • How to validate SSL certificate chain in ruby with net/http

    - by maledictus
    How can I verify the certificates of a site like https://processing.ukash.com/ in ruby with net/http? https = Net::HTTP.new('processing.ukash.com', 443) https.use_ssl = true https.verify_mode = OpenSSL::SSL::VERIFY_NONE Works so far, but how do I verify that it's the right cert now? I saved the certificate from within firefox, but the resulting .pem file has many certificates in it and net/http doesn't seem to like it.

  • regarding C++ stl container swap function

    - by sm1
    I recently learned that all stl containers have swap function: i.e. c1.swap(c2); will lead to object underlying c1 being assigned to c2 and vice versa. I asked my professor if same is true in case of c1 and c2 being references. he said same mechanism is followed. I wonder how it happens since c++ references cannot be reseted.

  • GAE update different fields of the same entity

    - by bach
    Hi, UserA and UserB are changing objectA.filedA objectA.filedB respectively and at the same time. Because they are not changing the same field one might think that there are no overlaps. Is that true? or the implementation of pm.makePersistnace() actually override the whole object... good to know...

  • How to return this XML-RPC response in an array using PHP?

    - by mind.blank
    I'm trying to put together a WordPress plugin and I want to grab a list of all categories (of other WordPress blogs) via XML-RPC. I have the following code and it looks like it works so far: function get_categories($rpcurl,$username,$password){ $rpcurl2 = $rpcurl."/xmlrpc.php"; $params = array(0,$username,$password,true); $request = xmlrpc_encode_request('metaWeblog.getCategories',$params); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $rpcurl2); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: text/xml")); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_TIMEOUT, 10); curl_setopt($ch, CURLOPT_POSTFIELDS, $request); $results = curl_exec($ch); $res = xmlrpc_decode($results); curl_close($ch); return $res; } If I use $res I get the following string as the response: Array If I use $results then I get: categoryId17 parentId0 descriptionTest categoryDescription categoryNameTest htmlUrlhttp://test.yoursite.com/?cat=17 rssUrlhttp://test.yoursite.com/?feed=rss2&amp;cat=17 categoryId1 parentId0 descriptionUncategorized categoryDescription categoryNameUncategorized htmlUrlhttp://test.yoursite.com/?cat=1 rssUrlhttp://test.yoursite.com/?feed=rss2&amp;cat=1 I need to pull out the names after description so Uncategorized and Test in this case. It's my first time coding in PHP. I got these results by echoing them to the page, so not sure if they get changed in that process or not... By the way I modified the above code from one that posts to a WordPress blog remotely so maybe I haven't set some of the options correctly? With var_dump($res) I get: array(2) { [0]=> array(7) { ["categoryId"]=> string(2) "17" ["parentId"]=> string(1) "0" ["description"]=> string(4) "Test" ["categoryDescription"]=> string(0) "" ["categoryName"]=> string(4) "Test" ["htmlUrl"]=> string(40) "http://test.youreventwebsite.com/?cat=17" ["rssUrl"]=> string(54) "http://test.youreventwebsite.com/?feed=rss2&cat=17" } [1]=> array(7) { ["categoryId"]=> string(1) "1" ["parentId"]=> string(1) "0" ["description"]=> string(13) "Uncategorized" ["categoryDescription"]=> string(0) "" ["categoryName"]=> string(13) "Uncategorized" ["htmlUrl"]=> string(39) "http://test.youreventwebsite.com/?cat=1" ["rssUrl"]=> string(53) "http://test.youreventwebsite.com/?feed=rss2&cat=1" } }
