  • mysql match against russain

    - by Devenv
    Hey, Trying to solve this for a very long time now... SELECT MATCH(name) AGAINST('????????') (russian) doesn't work, but SELECT MATCH(name) AGAINST('abraxas') (english) work perfectly. I know it's something with character-set, but I tried all kind of settings and it didn't work. For now it's latin-1.

  • Updating / refreshing a geojson layer

    - by Ozaki
    TLDR My geoJSON layer will display the vector mark but will not destroy the features or re add the features in causing a moving / updating look to the OpenLayers map. Hey S O. I have a geojson layer set up as follows: //GeoJSON Layer// var layer1 = new OpenLayers.Layer.GML("My GeoJSON Layer", "coordinates", {format: OpenLayers.Format.GeoJSON, styleMap: style_red}); My features are set up as follows: var f = new OpenLayers.Feature.Vector(null,style_red); var style_red = OpenLayers.Util.extend({}, layer_style); style_red.strokeColor = "red"; style_red.fillColor = "black"; style_red.fillOpacity = 0.5; style_red.graphicName = "circle"; style_red.pointRadius = 3.8; style_red.strokeWidth = 2; style_red.strokeLinecap = "butt"; and my layer updating function: function UpdateLayer(){ var p = new OpenLayers.Format.GeoJSON({ 'internalProjection': new OpenLayers.Projection("EPSG:900913"), 'externalProjection': new OpenLayers.Projection("EPSG:4326") }); var url = "coordinates.geojson"; OpenLayers.loadURL(url, {}, null, function(r) { var f = p.read(r.responseText); map.layers[1].destroyFeatures(); map.layers[1].addFeatures(f); }); setTimeout("UpdateLayer()",1000) } Any idea what I am doing wrong or what I am missing?

  • how to start a smartdevice application minimized in c#

    - by x86shadow
    I made a smart device application in c# and I want to run it at startup (I know how to do that) but the problem is that I can't make my application to run minimized (hidden) on the first time. I've tried this.Hide() and this.Visible = false and also used ShowWindow API with SW_HIDE(6) but non of them worked. It seems it's impossible to use these methods on Form_Load() or in InitializeComponent() to start the application minimized or hidden. anyone can help me with this ?

  • Grails bean-fields plugin

    - by Don
    Hi, I'm having problems using the Grails bean-fields plugin with a class this is annotated Validateable, but is not a domain/command class. The root cause of the problem appears to be in this method of BeanTagLib.groovy private def getBeanConstraints(bean) { if (bean?.metaClass?.hasProperty(bean, 'constraints')) { def cons = bean.constraints if (cons != null) { if (log.debugEnabled) { log.debug "Bean is of type ${bean.class} - the constraints property was a [${cons.class}]" } // Safety check for the case where bean is no a proper domain/command object // This avoids confusing errors where constraints comes back as a Closure if (!(cons instanceof Map)) { if (log.warnEnabled) { log.warn "Bean of type ${bean.class} is not a domain class, command object or other validateable object - the constraints property was a [${cons.class}]" } } } else { if (log.warnEnabled) { log.warn "Bean of type ${bean.class} has no constraints" } } return cons } else return null } I tested out this method above in the grails console and when I pass an instance of MyBean into this method, it logs: Bean of type ${bean.class} is not a domain class, command object or other validateable object - the constraints property was a [${cons.class}] Because the constraints are returned as an instance of Closure instead of a Map. If I could figue out how to get a Map reference to the constraints of a @Validateable class (that is not a domain/command class), I guess I could resolve the problem. Thanks, Don

  • Get "term is undefined” error when trying to assign arrayList to List component dataSource

    - by user1814467
    I'm creating an online game where people log in and then have the list of current players displayed. When the user enters a "room" it dispatches an SFSEvent which includes a Room object with the list of users as User objects in that room. As that event's callback function, I get the list of current users which is an Array, switch the View Stack child index, and then I wrap the user list array in an ArrayList before I assign it to the MXML Spark List component's dataSource. Here's my code: My Actionscript Code Section (PreGame.as): private function onRoomJoin(event:SFSEvent):void { const room:Room = this._sfs.getRoomByName(PREGAME_ROOM); this.selectedChild = waitingRoom; /** I know I should be using event listeners * but this is a temporary fix, otherwise * I keep getting null object errors * do to the li_users list not being * created in time for the dataProvider assignment **/ setTimeout(function ():void { const userList:ArrayList = new ArrayList(room.userList); this.li_users.dataProvider = userList; // This is where the error gets thrown },1000); } My MXML Code: <?xml version="1.0" encoding="utf-8"?> <mx:ViewStack xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" initialize="preGame_initializeHandler(event)" > <fx:Script source="PreGame.as"/> <s:NavigatorContent id="nc_loginScreen"> /** Login Screen Code **/ </s:NavigatorContent> /** Start of Waiting Room code **/ <s:NavigatorContent id="waitingRoom"> <s:Panel id="pn_users" width="400" height="400" title="Users"> /** This is the List in question **/ <s:List id="li_users" width="100%" height="100%"/> </s:Panel> </s:NavigatorContent> </mx:ViewStack> However, I keep getting this error: TypeError: Error #1010: A term is undefined and has no properties Any ideas what I'm doing wrong? The arrayList has data, so I know it's not empty/null.

  • Soon to be PhD in Computer Science - Which Path to Follow?

    - by mttr
    I am going to submit my PhD thesis within the next six months. My PhD is on managing the availabiity of large-scale distributed systems, so I have some experience actually building non-trivial systems (+ I have four years experience working as a programmer). I am now trying to figure out what I should do following the PhD. I enjoy research (a quick definition: identify problem, come up with solution, ask interesting questions, find ways to answer them, build system, experiment, contribute some new knowledge and publish). I also like teaching and supervising students. It would seem that a career in academia is the ideal thing to do (can work on non-trivial problems and contribute something of use to some or more people). However, a career in academia has two significant drawbacks. First, it can be difficult to gain access to real systems with real users which then display real problems. This creates the danger that you do work that seems important (to you and maybe to some of your colleagues), but is not really relevant to anything or anyone. Second, the pay is pretty sad. Apparently, you have to sacrifice this for the privilege of doing research. I enjoy programming, but don't just want to hack some web-based system for the rest of my life. That is, working in IT for a bank is not a future I see myself enjoying. I want to work on interesting problms (that's difficult to define clearly): things where you don't know how to start, that take some time to figure out and attack, that require a rigorous approach to demonstrate that the problem has been solved, and problems that need a solution in the real world. Give the experience of people on stackoverflow, what do you think suitable options are and why (or alternatively, what gaps in my thinking does the above reveal)? Is industrial research (aka IBM Research, Microsoft Research) the only alternative avenue to a career in academia? What other areas, companies, occupations, etc. could provide me with stimulating, inspiring work? Which regions, countries am I most likely to find such work? Please share your experience.

  • Clearing canvas with Canvas.drawColor()

    - by strangeInAStrangerLand
    I'm attempting to change the background image of a custom View with some success. The image will change but the problem is that I still see traces of the old image. When I attempt to clear the canvas before drawing the new image, it doesn't appear to work. I create a bitmap to store the image. When changing the image, I call Canvas.drawColor() before drawing the new image but the old image persists. I've tried drawColor(0), drawColor(Color.BLACK), c.drawColor(0, PorterDuff.Mode.CLEAR), and none of the above works. As such, I had to post this for review from more experienced minds than mine. The actual code is as follows: private int bgnd; private boolean switching; public void setBgnd(int incoming){ switching = true; switch (incoming){ case R.drawable.image1: bgnd = incoming; this.invalidate(); break; case R.drawable.image2: bgnd = incoming; this.invalidate(); break; } } protected void onDraw(Canvas c){ if(switching == true){ Bitmap b = BitmapFactory.decodeResource(getResources(), bgnd); c.drawColor(0, PorterDuff.Mode.CLEAR); c.drawBitmap(b, 0, 0, null); switching = false; }else{ Bitmap b = BitmapFactory.decodeResource(getResources(), bgnd); c.drawBitmap(b, 0, 0, null); } }

  • MINA: Performing synchronous write requests / read responses

    - by Matt Huggins
    I'm attempting to perform a synchronous write/read in a demux-based client application with MINA 2.0 RC1, but it seems to get stuck. Here is my code: public boolean login(final String username, final String password) { // block inbound messages session.getConfig().setUseReadOperation(true); // send the login request final LoginRequest loginRequest = new LoginRequest(username, password); final WriteFuture writeFuture = session.write(loginRequest); writeFuture.awaitUninterruptibly(); if (writeFuture.getException() != null) { session.getConfig().setUseReadOperation(true); return false; } // retrieve the login response final ReadFuture readFuture = session.read(); readFuture.awaitUninterruptibly(); if (readFuture.getException() != null) { session.getConfig().setUseReadOperation(true); return false; } // stop blocking inbound messages session.getConfig().setUseReadOperation(false); // determine if the login info provided was valid final LoginResponse loginResponse = (LoginResponse)readFuture.getMessage(); return loginResponse.getSuccess(); } I can see on the server side that the LoginRequest object is retrieved, and a LoginResponse message is sent. On the client side, the DemuxingProtocolCodecFactory receives the response, but after throwing in some logging, I can see that the client gets stuck on the call to readFuture.awaitUninterruptibly(). I can't for the life of me figure out why it is stuck here based upon my own code. I properly set the read operation to true on the session config, meaning that messages should be blocked. However, it seems as if the message no longer exists by time I try to read response messages synchronously. Any clues as to why this won't work for me?

  • Transitioning accordions from small height to full height with CSS

    - by arkanciscan
    I am building an accordion list and I want it to animate open and closed using a CSS -webkit-transition:. The animation is triggered by an event handler that simply toggles the .open class on and off. The problem is that when I click it, the animation goes from closed height to 0px height then jerks back to full height instead of smoothly animating to full height. HTML <ul class="accordion"> <li>Foo <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nunc quis leo sit amet justo vulputate volutpat. Suspendisse potenti. Aliquam aliquet justo ut turpis suscipit adipiscing.</p> </li> <li class="open">Baz <p>Ut velit magna, sagittis at blandit accumsan, vestibulum et dolor. Aliquam elit ante, congue vel pharetra ut, ultricies non est. In hac habitasse platea dictumst. Donec velit ligula, sodales a imperdiet non, sagittis id mauris.</p> </li> <li>Bar <p>Cras sit amet gravida lacus. Nulla consequat molestie nunc nec fermentum. Donec lobortis pretium quam sit amet scelerisque.</p> </li> </ul>? Javascript $('.accordion').delegate('li', 'click', function(li){ $(this).toggleClass('open'); }); Css .accordion li.open{ -webkit-transition: height 1s; } .accordion li:not(.open){ height: 1em; -webkit-transition: height 1s; } ? Try it on JSFiddle and see what I mean. I've already figured out how to make it work, but it requires setting an explicit height on the .open class. The accordions have variable height however, and creating an explicit selector for each one is obtrusive and unmaintainable. Can anyone give me a better solution than this? Here it is working with an explicit height that doesn't fit the content

  • FancyBox Callback Keydown

    - by headShrinker
    I have been working on this code, and I can't seem to figure it out. Fancybox's callbacks don't seem to work at all. I have the keyboard bound to the pagination for this gallery. But I want to unbind the keyboard from the table when fancybox opens. When fancybox opens nothing changes.... What to do?? $(document).ready(function() { $('a.active').click(function() { var url = $(this).attr('href'); $('#ajaxTable').load(url+'/1'); return false; }); $("a.fancy").fancybox({ callbackOnStart: function() { $('a#gleft a#gright').unbind("keydown"); }, 'frameWidth': 570, 'frameHeight': 470 }) $(document).keydown(function(event) { if(event.keyCode == 37 ) { var url = $('a#gleft').attr('href'); if (url != null) { $('#ajaxTable').load(url+'/1'); $(document).unbind("keydown"); } } else if(event.keyCode == 39 ) { var url = $('a#gright').attr('href'); if (url != null) { $('#ajaxTable').load(url+'/1'); $(document).unbind("keydown"); } } }); });

  • Locking down RAD Studio internal browser security.

    - by HMcG
    I use Firefox as my web browser, mostly for access to add-ins such as Flashblock and No-script. I noticed yesterday that the RAD Studio internal browser used for the Welcome Page etc has scripting and Active X etc enabled. Is there a way to disable scripting, or better still, block all access to non-local sources in the built-in browser?

  • Webservice returning 403 error

    - by user48408
    I'm wondering whether I'm receiving the 403 errors because there are too many attempted connections being made to the webservice. If this is the case how do I get around it? I've tried creating a new instance of InternalWebService each time and disposing of the old one but I get the same problem. I've disabled the firewall and the webservice is located locally at the moment. I beginning to think it may be a problem with the credentials but the control tree is populated via the webservice at some stage. If I browse to the webmethods in my browser I can run them all. I return an instance of the webservice from my login handler loginsession.cs: static LoginSession() { ... g_NavigatorWebService = new InternalWebService(); g_NavigatorWebService.Credentials = System.Net.CredentialCache.DefaultCredentials; ... } public static InternalWebService NavigatorWebService { get { return g_NavigatorWebService; } } I have a tree view control which uses the webservice to populate itself. IncidentTreeViewControl.cs: public IncidentTreeView() { InitializeComponent(); m_WebService = LoginSession.NavigatorWebService; ... } public void Populate() { m_WebService.BeginGetIncidentSummaryByCompany(new AsyncCallback(IncidentSummaryByClientComplete), null); m_WebService.BeginGetIncidentSummaryByDepartment(new AsyncCallback(IncidentSummaryByDepartmentComplete), null); ... } private void IncidentSummaryByClientComplete(IAsyncResult ar) { MyTypedDataSet data = m_WebService.EndGetIncidentSummaryByCompany(ar); //403 ..cont... } I'm getting the 403 on the last line.

  • Problem Activating Sharepoint Timer Job

    - by Ben Robinson
    I have created a very simple sharepoint timer job. All i want it to do is iterate through a list and update each list item so that it triggers an existing workflow that works fine. In other words all i am trying to do is work around the limitation that workflows cannot be triggered on a scheduled basis. I have written a class that inherits from SPJobDefinition that does the work and i have a class that inherits from SPFeatureReceiver to install and activate it. I have created the feature using SPVisualdev that my coleagues have used in the past for other SP development. My Job class is below: public class DriverSafetyCheckTrigger : SPJobDefinition { private string pi_SiteUrl; public DriverSafetyCheckTrigger(string SiteURL, SPWebApplication WebApp):base("DriverSafetyCheckTrigger",WebApp,null, SPJobLockType.Job) { this.Title = "DriverSafetyCheckTrigger"; pi_SiteUrl = SiteURL; } public override void Execute(Guid targetInstanceId) { using (SPSite siteCollection = new SPSite(pi_SiteUrl)) { using (SPWeb site = siteCollection.RootWeb) { SPList taskList = site.Lists["Driver Safety Check"]; foreach(SPListItem item in taskList.Items) { item.Update(); } } } } } And the only thing in the feature reciever class is that i have overridden the FeatureActivated method below: public override void FeatureActivated(SPFeatureReceiverProperties Properties) { SPSite site = Properties.Feature.Parent as SPSite; // Make sure the job isn't already registered. foreach (SPJobDefinition job in site.WebApplication.JobDefinitions) { if (job.Name == "DriverSafetyCheckTrigger") job.Delete(); } // Install the job. DriverSafetyCheckTrigger oDriverSafetyCheckTrigger = new DriverSafetyCheckTrigger(site.Url, site.WebApplication); SPDailySchedule oSchedule = new SPDailySchedule(); oSchedule.BeginHour = 1; oDriverSafetyCheckTrigger.Schedule = oSchedule; oDriverSafetyCheckTrigger.Update(); } The problem i have is that when i try to activate the feature it throws a NullReferenceException on the line oDriverSafetyCheckTrigger.Update(). I am not sure what is null in this case, the example i have followed for this is this tutorial. I am not sure what I am doing wrong.

    See code just bellow Our generic interface public interface Repository<INSTANCE_CLASS, INSTANCE_ID_CLASS> { void add(INSTANCE_CLASS instance); INSTANCE_CLASS getById(INSTANCE_ID_CLASS id); } And a single class public class Order { private Integer id; private Integer orderNumber; // getter's and setter's public void equals(Object o) { if(o == null) return false; if(!(o instanceof Order)) return false; // business key if(getOrderNumber() == null) return false; final Order other = (Order) o; if(!(getOrderNumber().equals(other.getOrderNumber()))) return false; return true; } // hashcode } And when i do the following test private Repository<Order, Integer> repository; @Before public void setUp { repository = EasyMock.createMock(Repository.class); Order order = new Order(); order.setOrderNumber(new Integer(1)); repository.add(order); EasyMock.expectLasCall().once(); EasyMock.replay(repository); } @Test public void addOrder() { Order order = new Order(); order.setOrderNumber(new Integer(1)); repository.add(order); EasyMock.verify(repository) } I get Unexpected method call add(br.com.smac.model.domain.Order@ac66b62): add(br.com.smac.model.domain.Order@ac66b62): expected: 1, actual: 0 Why does it not work as expected ??? What should i do to pass the test ???

  • Where my memory is alloced, Stack or Heap, Can I find it at Run-time?

    - by AKN
    I know that memory alloced using new, gets its space in heap, and so we need to delete it before program ends, to avoid memory leak. Let's look at this program... Case 1: char *MyData = new char[20]; _tcscpy(MyData,"Value"); . . . delete[] MyData; MyData = NULL; Case 2: char *MyData = new char[20]; MyData = "Value"; . . . delete[] MyData; MyData = NULL; In case 2, instead of allocating value to the heap memory, it is pointing to a string literal. Now when we do a delete it would crash, AS EXPECTED, since it is not trying to delete a heap memory. Is there a way to know where the pointer is pointing to heap or stack? By this the programmer Will not try to delete any stack memory He can investigate why does this ponter, that was pointing to a heap memory initially, is made to refer local literals? What happened to the heap memory in the middle? Is it being made to point by another pointer and delete elsewhere and all that?

  • CodeDom : compile partial class

    - by James
    I'm attempting to compile code in a text file to change a value in a TextBox on the main form of a WinForms application. Ie. add another partial class with method to the calling form. The form has one button (button1) and one TextBox (textBox1). The code in the text file is: this.textBox1.Text = "Hello World!!"; And the code: namespace WinFormCodeCompile { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { // Load code from file StreamReader sReader = new StreamReader(@"Code.txt"); string input = sReader.ReadToEnd(); sReader.Close(); // Code literal string code = @"using System; using System.Windows.Forms; namespace WinFormCodeCompile { public partial class Form1 : Form { public void UpdateText() {" + input + @" } } }"; // Compile code CSharpCodeProvider cProv = new CSharpCodeProvider(); CompilerParameters cParams = new CompilerParameters(); cParams.ReferencedAssemblies.Add("mscorlib.dll"); cParams.ReferencedAssemblies.Add("System.dll"); cParams.ReferencedAssemblies.Add("System.Windows.Forms.dll"); cParams.GenerateExecutable = false; cParams.GenerateInMemory = true; CompilerResults cResults = cProv.CompileAssemblyFromSource(cParams, code); // Check for errors if (cResults.Errors.Count != 0) { foreach (var er in cResults.Errors) { MessageBox.Show(er.ToString()); } } else { // Attempt to execute method. object obj = cResults.CompiledAssembly.CreateInstance("WinFormCodeCompile.Form1"); Type t = obj.GetType(); t.InvokeMember("UpdateText", BindingFlags.InvokeMethod, null, obj, null); } } } } When I compile the code, the CompilerResults returns an error that says WinFormCodeCompile.Form1 does not contain a definition for textBox1. Is there a way to dynamically create another partial class file to the calling assembly and execute that code? I assume I'm missing something really simple here.

  • Why does calling abort() on ajax request cause error in ASP.Net MVC (IE8)

    - by user169867
    I use jquery to post to an MVC controller action that returns a table of information. The user of the page triggers this by clicking on various links. In the event the user decides to click a bunch of these links in quick succession I wanted to cancel any previous ajax request that may not have finished. I've found that when I do this (although its fine from the client's POV) I will get errors on the web application saying that "The parameters dictionary contains a null entry for parameter srtCol of non-nullable type 'System.Int32'" Now the ajax post deffinately passes in all the parameters, and if I don't try and cancel the ajax request it works just fine. But if I do cancel the request by calling abort() on the XMLHttpRequest object that ajax() returns before it finishes I get the error from ASP.Net MVC. Example: //Cancel any pevious request if (req) { req.abort(); req = null; } //Make new request req= $.ajax({ type: 'POST', url: "/Myapp/GetTbl", data: {srtCol: srt, view: viewID}, success: OnSuccess, error: OnError, dataType: "html" }); I've noticed this only happen is IE8. In FF it seems to not cuase a problem. Does anyone know how to cancel an ajax request in IE8 without causing errors for MVC? Thanks for any help.

  • Shopify JSONP issue in ajaxAPI

    - by Aaron U
    I'm getting some odd response back from shopify ajaxapi for jsonp. If you cURL a Shopify ajax api location http://storename.domain.com/cart.json?callback=handler you will get a jsonp response. But something is breaking the same request in browsers. It appears to be related to compression? Here are some responses from each browser when attempting to call the jsonp as documented. Firefox: The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression. Internet Explorer: Internet Explorer cannot display the webpage Chrome/Safari/Webkit: Cannot decode raw data, or failed (chrome) Attempted use via jquery: $.getJSON('http://storename.domain.com/cart.json?callback=?', function(data) { ... }); // Results in a failed request, viewable network request panels of dev tools Here is some output from cURL including response headers: $ curl -i http://storename.domain.com/cart.json?callback=CALLBACK_FUNC HTTP/1.1 200 OK Server: nginx Date: Tue, 18 Dec 2012 13:48:29 GMT Content-Type: application/javascript; charset=utf-8 Transfer-Encoding: chunked Connection: keep-alive Status: 200 OK ETag: cachable:864076445587123764313132415008994143575 Cache-Control: max-age=0, private, must-revalidate X-Alternate-Cache-Key: cachable:11795444887523410552615529412743919200 X-Cache: hit, server X-Request-Id: a0c33a55230fe42bce79b462f6fe450d X-UA-Compatible: IE=Edge,chrome=1 Set-Cookie: _session_id=b6ace1d7b0dbedd37f7787d10e173131; path=/; HttpOnly X-Runtime: 0.033811 P3P: CP="NOI DSP COR NID ADMa OPTa OUR NOR" CALLBACK_FUNC({"token":null,"note":null,"attributes":{},"total_price":0,...}) Also related unanswered here: Shopify Ajax API JSONP supported?

  • Does python's httplib.HTTPConnection block?

    - by python_noob
    Hello, I am unsure whether or not the following code is a blocking operation in python: import httplib import urllib def do_request(server, port, timeout, remote_url): conn = httplib.HTTPConnection(server, port, timeout=timeout) conn.request("POST", remote_url, urllib.urlencode(query_dictionary, True)) conn.close() return True do_request("http://www.example.org", 80, 30, "foo/bar") print "hi!" And if it is, how would one go about creating a non-blocking asynchronous http request in python? Thanks from a python noob.
