  Hi everyone, I am trying to call a method that passes an object called parameters. public void LoadingDataLockFunctionalityTest() { DataCache_Accessor target = DataCacheTest.getNewDataCacheInstance(); target.itemsLoading.Add("WebFx.Caching.TestDataRetrieverFactorytestsync", true); DataParameters parameters = new DataParameters("WebFx.Core", "WebFx.Caching.TestDataRetrieverFactory", "testsync"); parameters.CachingStrategy = CachingStrategy.TimerDontWait; parameters.CacheDuration = 0; string data = (string)target.performGetForTimerDontWaitStrategy(parameters); TestSyncDataRetriever.SimulateLoadingForFiveSeconds = true; Thread t1 = new Thread(delegate() { string s = (string)target.performGetForTimerDontWaitStrategy(parameters); Console.WriteLine(s ??

Can someone please put me in the right direction Thanks

• Is there a Designer for MFC in Visual Studio like for windows forms in .NET?

  - by claws

  I'm a .NET programmer. I've never developed anything in MFC. Currently I had to write a C++ application (console) for some image processing task. I finished writing it. But the point is I need to design GUI also for this. Well, there won't be anything complex. Just a window with few Buttons, RadioButtons, Check Boxes, PicturesBox & few sliders. thats it. I'm using VS 2008 and was expecting a .NET style form designer. Just to test, I created a MFC project (with all default configuration) and these files were created by default: ChildFrm.cpp MainFrm.cpp mfc.cpp mfcDoc.cpp mfcView.cpp stdafx.cpp Now, I'm unable to find a Designer. There is no View Designer. I've opened all the above *.cpp and in the code editor right clicked to see "Designer View". ToolBox is just empty because I'm in code editor mode. When I built the project. This is the window I get. How to open a designer?

• How to get jQuery to find the first list-item, rather than all list-items?

  - by ricebowl

  I'm trying to implement a basic jQuery infinite carousel. As much for the learning process as for anything else (as a rule I'm not a fan of re-inventing wheels, but...I have to learn somehow, might as well start with the basics). I've managed to get the list to animate left happily enough, but I'm stuck when it comes to selecting the first element of the list. I've tried to use: $('ul#services > li:first'); $('ul#services > li:first-child'); $('ul#services > li').eq([0]); (xhtml below), In each case a console.log(first) (the var name used) returns all of the list-items. Am I doing something blatantly, and obviously, wrong? The eventual plan is to clone the first li, append it to the parent ul, remove the li from the list and allow the list to scroll infinitely. It's just a list of services rather than links so I'm not -at the moment- planning to have scroll or left/right functionality. Current xhtml: <div class="wrapper"> <ul id="services"> <!-- closing the `</li>` tags on the following line is to remove whitespace in the horizontal list, doesn't seem to make a difference to the jQuery from my own testing. --> <li>one</li ><li>two</li ><li>three</li ><li>four</li ><li>five</li ><li>six</li ><li>seven</li ><li>eight</li ><li>nine</li ><li>ten</li> </ul> </div>

• Hibernate saveOrUpdate fails when I execute it on empty table.

  - by Vladimir

  I'm try to insert or update db record with following code: Category category = new Category(); category.setName('catName'); category.setId(1L); categoryDao.saveOrUpdate(category); When there is a category with id=1 already in database everything works. But if there is no record with id=1 I got following exception: org.hibernate.StaleStateException: Batch update returned unexpected row count from update [0]; actual row count: 0; expected: 1: Here is my Category class setters, getters and constructors ommited for clarity: @Entity public class Category { @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; private String name; @ManyToOne private Category parent; @OneToMany(fetch = FetchType.LAZY, mappedBy = "parent") private List<Category> categories = new ArrayList<Category>(); } In the console I see this hibernate query: update Category set name=?, parent_id=? where id=? So looks like hibernates tryis to update record instead of inserting new. What am I doing wrong here?

• Windows Service Start-Up Error 1069

  - by Gavin

  Hello, I am installing a new windows service coded in C# on a server. I installed the service fine on the server, but once i manually start up the service on a server, with the same login credentials that our other services use, i get the fatal error message notification: "Could not start the %service name% on Local Computer. Error 1069: The Service did not start due to a logon failure." I looked in the event log and i got a 7038 and 7000 event id error in that order. 7038 event id message: "The %service name% service was unable to log on as %login% with the currently configured password due to the following error: Logon failure: unknown user name or bad password. To ensure that the service is configured properly, use the Services snap-in in Microsoft Management Console (MMC)." 7000 event id message: "The %service name% service failed to start due to the following error: The service did not start due to a logon failure. " I have other services that are using the same exact login account and they work fine. Is there something simple I could be missing? Thanks

• Storing records in a dropdownlist from DB without using LINQ Data source

  - by user1318369

  I have a website for dance academy where Users can register and add/drop dance classes. In the web page to drop a particular dance, for a particular user, the dropdown displays her registered dances. Now I want to delete one of the dances from the list. So i'll remove the row from the table and also from the dropdownlist. The problem is that everytime the item with the lowest ID (index) is getting deleted, no matter which one the user selects. I think I am storing the DataTextField and DataValueField for the dropdown incorrectly. Can someone please help me out? The code is: private void PopulateDanceDropDown() { var registereddanceList = from dd in context.DANCER_AND_DANCE where dd.UserId == dancerId select new { Text = dd.DanceName, Value = dd.DanceId }; dances.DataSource = registereddanceList; dances.DataTextField = "Text"; dances.DataValueField = "Value"; dances.DataBind(); } protected void dropthedance(object o, EventArgs e) { String strDataValueField = dances.SelectedItem.Value; int danceIDFromDropDown = Convert.ToInt32(strDataValueField); var dancer_dance = from dd in context.DANCER_AND_DANCE where dd.DanceId == danceIDFromDropDown select dd; foreach (var dndd in dancer_dance) { context.DANCER_AND_DANCE.DeleteOnSubmit(dndd); } try { context.SubmitChanges(); } catch (Exception ex) { Console.WriteLine(ex); } PopulateDanceDropDown(); }

• Running an application from an USB device...

  - by Workshop Alex

  I'm working on a proof-of-concept application, containing a WCF service with console host and client, both on a single USB device. On the same device I will also have the client application which will connect to this service. The service uses the entity framework to connect to the database, which in this POC will just return a list of names. If it works, it will be used for a larger project. Creating the client and service was easy and this works well from USB. But getting the service to connect to the database isn't. I've found this site, suggesting that I should modify machine.config but that stops the XCopy deployment. This project cannot change any setting of the PC, so this suggestion is bad. I cannot create a deployment setup either. The whole thing just needs to run from USB disk. So, how do I get it to run? (The service just selects a list of names from the database, which it returns to the client. If this POC works, it will do far more complex things!)

• contentscript, dynamic created iframe, postmessage

  - by thefoyer

  I'm attempting to inject an iframe from a content script. From the content script, post a message to the iframe, without much success. This is the closest I have got. No errors/warnings in the console but it doesn't work (alert test). contentscript: var iframe = document.createElement("iframe"); iframe.setAttribute("src", "https://www.com/iframe.php"); iframe.id = "iframe01"; document.getElementsByTagName("body")[0].appendChild(iframe); //then I inject this "web_accessible_resources" script var script = document.createElement("script"); script.type = "text/javascript"; script.src = chrome.extension.getURL("postMessage.js"); document.getElementsByTagName("head")[0].appendChild(script); postMessage.js window.postMessage({msg: "test"}, "*"); I've also tried top.postMessage({msg: "test"}, "*"); And var iframe = document.getElementById('iframe01'); iframe.contentWindow.postMessage({msg: "test"}, "*"); EDIT: I tried to make sure the iframe was loaded before postMessage, even if I put an alert there, it would alert telling me the iframe was loaded. var iframe = document.getElementById('iframe01'); if (ifrm_prsto.contentWindow.document) //do postMessage EDIT2: I did get it to work by moving the iframe from the contentscript to the inject.js script. Wasn't totally ideal but I do have it working now, I guess. iframe.php window.addEventListener("message", function(e) {alert("test");}); I am however able to do the reverse, talk to the parent script from the iframe.

• Exchange Server 2010: move mailboxes from recoveded and mounted edb to user's mailbox [closed]

  - by Cook

  One of our exchange servers crashed, and I am trying to recover the mailboxes. We had 1 exchange 2003 server named "apex" and 1 exchange 2010 server named "2008Enterprise. the exchange 2010 server named "2008Enterprise" crashed. I created a new exchange 2010 server named "Providence". I ran the command on Providence: New-MailboxDatabase -Recovery -Name JBCMail -Server Providence -EdbFilePath "c:\data\Exchange\Mailbox\Mailbox Database 0579285147\Mailbox Database 0579285147.edb" -LogFolderPath "c:\data\Exchange\Mailbox\Mailbox Database 0579285147" this command executed and finished without error I then ran the command: eseutil /p E00 this command was executed from the below directory: c:\data\Exchange\Mailbox\Mailbox Database 0579285147 I then mounted the JBCMail with the mount command note: I do not have my full typed command. Inside my Exchange Management Console (EMC) I can view the new mailbox database named JBCMail. The JBCMail database is show as mounted on the exchange server named Providence. I can see the crashed Exchange server named 2008Exchange. In the EMC the crashed exchange server states the Copy Status under ServerConfiguration-Mailbox is ServiceDown. From here I need to recover three mailboxes The mail boxes are on the apex server. How do I move the mailboxs from apex to Providence? How do I restore the mailboxes from JBCmail mounted database to the user's mailbox? I do not fully understand how to use the Restore-Mailbox command because when I use this command it tries to restore the mailbox to the dead apex server.

• Updating a C# 2.0 events example to be idiomatic with C# 3.5?

  - by Damien Wildfire

  I have a short events example from .NET 2.0 that I've been using as a reference point for a while. We're now upgrading to 3.5, though, and I'm not clear on the most idiomatic way to do things. How would this simple events example get updated to reflect idioms that are now available in .NET 3.5? // Args class. public class TickArgs : EventArgs { private DateTime TimeNow; public DateTime Time { set { TimeNow = value; } get { return this.TimeNow; } } } // Producer class that generates events. public class Metronome { public event TickHandler Tick; public delegate void TickHandler(Metronome m, TickArgs e); public void Start() { while (true) { System.Threading.Thread.Sleep(3000); if (Tick != null) { TickArgs t = new TickArgs(); t.Time = DateTime.Now; Tick(this, t); } } } } // Consumer class that listens for events. public class Listener { public void Subscribe(Metronome m) { m.Tick += new Metronome.TickHandler(HeardIt); } private void HeardIt(Metronome m, TickArgs e) { System.Console.WriteLine("HEARD IT AT {0}",e.Time); } } // Example. public class Test { static void Main() { Metronome m = new Metronome(); Listener l = new Listener(); l.Subscribe(m); m.Start(); } }

• Jquery failure after site went live

  - by Brandon Condrey

  I have been designing a site for weeks using JQuery. I don't have a local server or a testing server so I just created a directory through FTP, '/testing'. Everything was working great in the testing directory. I attempted to go live tonight by moving all the files in '/testing' to the root directory and I changed all file paths and script sources accordingly. The site loads, but everything related to JQuery is non-functional. Javascript console gives errors of (just as an example from a plugin): '$.os.name' is not a function I'm at loss for what to do. I changed the paths referencing the JQuery library, installed a fresh copy of JQuery (to a new directory), etc. There is a wordpress installation in a different directory '/blog'. I've read about some compatibility issues with wordpress, but that seems to be related to using JQuery inside wordpress, which I am not. I'm not sure if any code would be beneficial since it was all functional in a different directory. Your help is greatly appreciated.

• Unit-testing a directive with isolated scope and bidirectional value

  I want to unit test a directive which looks like this: angular.module('myApp', []) .directive('myTest', function () { return { restrict: 'E', scope: { message: '='}, replace: true, template: '<div ng-if="message"><p>{{message}}</p></div>', link: function (scope, element, attrs) { } }; }); Here is my failing test: describe('myTest directive:', function () { var scope, compile, validHTML; validHTML = '<my-test message="message"></my-test>'; beforeEach(module('myApp')); beforeEach(inject(function($compile, $rootScope){ scope = $rootScope.$new(); compile = $compile; })); function create() { var elem, compiledElem; elem = angular.element(validHTML); compiledElem = compile(elem)(scope); scope.$digest(); return compiledElem; } it('should have a scope on root element', function () { scope.message = 'not empty'; var el = create(); console.log(el.text()); expect(el.text()).toBeDefined(); expect(el.text()).not.toBe(''); }); }); Can you spot why it's failing?

• Recaptcha with Ajax error

  - by Brandon

  I'm having trouble validating a recaptcha input. Heres my code: // Validate Recaptcha Input var challenge = $("#recaptcha_challenge_field").val(); var response = $("#recaptcha_response_field").val(); var dataString = 'recaptcha_challenge_field=' + challenge + '&recaptcha_response_field=' + response; var html = $.ajax({ type: "POST", url: "PHP/recaptchaverify.php", data: dataString, async: true }).responseText; console.log(html); if(html == 'accept') { alert("CORRECT"); } else { alert("The reCAPTCHA wasn't entered correctly. Go back and try it again."); $("#recaptcha_response_field").focus(); Recaptcha.reload(); return false; } Now I passed my variables to recpatchaverify.php require_once('../scripts/recaptcha-php/recaptchalib.php'); $privatekey = "MYKEY"; $resp = recaptcha_check_answer ($privatekey, $_SERVER["REMOTE_ADDR"], $_POST["recaptcha_challenge_field"], $_POST["recaptcha_response_field"]); if (!$resp->is_valid) { // What happens when the CAPTCHA was entered incorrectly echo "error"; } else { // Your code here to handle a successful verification echo "accept"; } Now my problem is the html variable is displaying "accept" whenever I enter the Recaptcha correctly, but it won't work in the IF statement?

• Execute external program from Java

  - by Saurabh Lalwani

  Hi, I am trying to execute a program from the Java code. Here is my code: public static void main(String argv[]) { try { String line; Process p = Runtime.getRuntime().exec( "/bin/bash -c ls > OutputFileNames.txt"); BufferedReader input = new BufferedReader( new InputStreamReader(p.getInputStream())); while ((line = input.readLine()) != null) { System.out.println(line); } input.close(); } catch (Exception err) { err.printStackTrace(); } } My OS is Mac OS X 10.6. If I remove the "> OutputFileNames.txt" from the getRuntime().exec() method, all the file names are printed on the console just fine. But I need it to be printed to a file. Also, if I change the command to: Process p = Runtime.getRuntime().exec( "cmd \c dir > OutputFileNames.txt"); and run it on Windows, it runs and prints the results in the file perfectly fine too. I have read the other posts for executing another application from Java but none seemed to relate to my problem. I would really appreciate any help I can get. Thanks,

• Planning a programming project by example (C# or C++)

  - by Lunan

  I am in the last year of undergraduate degree and i am stumped by the lack of example in c++ and c# large project in my university. All the mini project and assignment are based on text based database, which is so inefficient, and console display and command, which is frustrating. I want to develop a complete prototype of corporate software which deals in Inventory, Sales, Marketing, etc. Everything you would usually find in SAP. I am grateful if any of you could direct me to a books or article or sample program. Some of the question are : How to plan for this kind of programming? should i use the concept of 1 object(such as inventory) have its own process and program and have an integrator sit for all the program, or should i integrate it in 1 big program? How to build and address a database? i have little bit knowledge in database and i know SQL but i never address database in a program before. Database are table, and how do you suppose to represent a table in a OOP way? For development type, which is better PHP and C++ or C# and ASP.NET? I am planning to use Web Interface to set form and information, but using a background program to handle the compute. .NET is very much integrated and coding should be much faster, but i really wonder about performance if compared to PHP and C++ package thank you for the info

• Meteor: how to update DOM via Javascript without a page refresh?

  - by strack

  UPDATE: It looks like this script may be the catalyst I'm looking for. Will test it and answer/close this question if so. I'm sure I'll find the answer to this eventually, but I'm putting it out there now, in case someone else knows it right off... I am using RaphaelJS to manipulate the DOM (adds a bunch of SVG tags to an identified DIV), and I want to re-render those specific DOM parts, if there's an update to the MongoDB collection. As an example: -Let's say that I have a collection called PiePieces. -When the page is first rendered/ called, let's pretend that the number of pieces in the collection is 4. -I programmatically add a pie piece using console: PiePieces.insert({...}) -I want the page to update like it would for a standard handlebars binding situation, but the problem is, the new entry needs to go through the Raphael script, which performs direct DOM manipulation. So, the logic would go something like this: MongoDB collection update event - Client function call to manipulate DOM - DOM modified/ page updated without a refresh. I've tried implementing this by reading values from the DOM itself, and I can get the updated DOM, but the entire page refreshes and/or I have to manually refresh the page, OR the DOM tree isn't completed yet, and so it's blank until I refresh. Can you point me in the right direction, maybe with a small code snippet/example? (if something similar already exists, just tell me where and I'll go digging) Thanks in advance! (I am LOVING Meteor so far...)

• Qt: How to use QTimer to print a message to a QTextBrowser every 10 seconds?

  - by Aaron McKellar

  Hello, I have working at this for hours and cannot figure it out nor can I find any help online that works. Basically the gist of what I am trying to accomplish is to have a Qt GUI with a button and a QTextBrowser. When I push the button I want it to diplay a message and then keep printing this message every 10 seconds. I figured I would use QTimer because it makes sense to have a timer to diplay the message every 10 seconds. When I originally implemented this into my buttonClicked() SLOT it caused the program to freeze. I looked online for a solution and found QApplication::processEvents(). So basically in my function I had something like this: while(1) { QTimer *timer; connect(...) //omitted parameters for this example timer.start(10000); ui->diplay->append("Message"); while(timer.isActive()) { QApplication::processEvents() } } I figured it would break out of the timer.isActive() while loop but it won't it simply stays in there. So I figured this is a threading issue. So I figured out how to use QThreads but I still can't get it to work. Basically when I create a thread with a timer on it and the thread tells the timer to start, the program closes and the console says "The program has unexpectedly finished". There has to be an easy way to do this but my track record with Qt has always been that th

• Multi Player game using Nodejs and Socket IO

  - by Kishorevarma

  I am trying out multi player racing game using Node and Socket IO ,express . So I have tried simple example to see the latency between node server and the clients. I have a draggable image in client . when I move the image ienter code heren one client ,it has to move in all clients. so basically when I am moving the image I am sending the image position to the node server in a json format , then from there I am broadcasting to all clients. there is a ~approx 300ms latency from the time. following are the results. Client 1 sending data to server at : 286136 (timestamp) Server received at : 286271 Client2 received data at : 286470 Client3 received data at : 286479 Client4 received data at : 286487 Client5 received data at : 286520 the latency between move from client1 to client5 is 384ms. its too hight for a racing game .. here is my server code. var app = require('express').createServer(); var io = require('socket.io'); var http = require('http'); var http_server = http.createServer(); var server = http.createServer(app); server.listen(3000); var socket = io.listen(server,{ log: false }); socket.sockets.on('connection', function (client) { client.on('message', function (data){ console.log("data arrived to server",new Date().getTime()); // Below both statements are giving same latency between the client 1 and client 5 client.broadcast.emit('message',data); //socket.sockets.emit('message',data); }); }); 1) Is there any way to optimize the server code to reduce the latency? 2) is this expected latency using node and websockets ? 3) is socket io can't broadcast the data asynchronously (I mean at a same time) ? Thanks Kishorevarma

• How to use Node.js to build pages that are a mix between static and dynamic content?

  - by edt

  All pages on my 5 page site should be output using a Node.js server. Most of the page content is static. At the bottom of each page, there is a bit of dynamic content. My node.js code currently looks like: var http = require('http'); http.createServer(function (request, response) { console.log('request starting...'); response.writeHead(200, { 'Content-Type': 'text/html' }); var html = '<!DOCTYPE html><html><head><title>My Title</title></head><body>'; html += 'Some more static content'; html += 'Some more static content'; html += 'Some more static content'; html += 'Some dynamic content'; html += '</body></html>'; response.end(html, 'utf-8'); }).listen(38316); I'm sure there are numerous things wrong about this example. Please enlighten me! For example: How can I add static content to the page without storing it in a string as a variable value with += numerous times? What is the best practices way to build a small site in Node.js where all pages are a mix between static and dynamic content?

• Retrieve nested list from XDocument with LINQ

  - by twreid

  Ok I want my link query to return a list of users. Below is the XML <section type="Users"> <User type="WorkerProcessUser"> <default property="UserName" value="Main"/> <default property="Password" value=""/> <default property="Description" value=""/> <default property="Group" value=""/> </User> <User type="AnonymousUser"> <default property="UserName" value="Second"/> <default property="Password" value=""/> <default property="Description" value=""/> <default property="Group" value=""/> </User> </section> And my current LINQ Query that doesn't work. doc is an XDocument var users = (from iis in doc.Descendants("section") where iis.Attribute("type").Value == "Users" from user in iis.Elements("User") from prop in user.Descendants("default") select new { Type = user.Attribute("type").Value, UserName = prop.Attribute("UserName").Value }); This does not work can anyone tell me what I need to fix? Here is my second attempt after fixing for the wrong property name. However this one does not seem to enumerate the UserName value for me when I try to use it or at least when I try to write it to the console. Also this returns 8 total results I should only have 2 results as I only have 2 users. (from iis in doc.Descendants("section") where iis.Attribute("type").Value == "Users" from user in iis.Elements("User") from prop in user.Descendants("default") select new { Type = user.Attribute("type").Value, UserName = (from name in prop.Attributes("property") where name.Value == "UserName" select name.NextAttribute.Value).ToString() });
