• How can I disable Ctrl+A (select all) using jquery in a browser?

  - by Keltex

  I'm trying to prevent information to be copied from a page (for non-technical users of course). I know how to disable selecting text using the mouse. The following jquery code works: $(function(){ $.extend($.fn.disableTextSelect = function() { return this.each(function(){ if($.browser.mozilla){//Firefox $(this).css('MozUserSelect','none'); }else if($.browser.msie){//IE $(this).bind('selectstart',function(){return false;}); }else{//Opera, etc. $(this).mousedown(function(){return false;}); }); }); $('.noSelect').disableTextSelect(); }); But users can still use Ctrl+A to select the entire page. Any workarounds for this?

• Retrieving FBO data in GLSL

  - by Tom Savage

  I'm trying to get MRT working in OpenGL to try out deferred rendering. Here's the situation as I understand it. Create 3 render buffers (for example). Two RGBA8 and one Depth32. Create an FBO. Attach render buffers to FBO. ColorAttachment0/1 for color buffers, DepthAttachment for depth buffer. Bind the FBO. Draw geometry. Send data to different attachments using gl_FragData[] in the frag shader. At this point I would want to take the data in another pass using GLSL, how can a) retrieve data from the framebuffer color attachments, b) get data from the depth component.

• InfoPath Repeating Group with Data from SharePoint and User Input

  - by 0x808080

  I have a series of questions which are pulled from a SharePoint list and loaded into a repeating section. The section has three elements, the Question # (from SharePoint), and Question itself (from SharePoint), and a drop down box Yes/No (NOT from SharePoint)... The repeating group portion works just fine, it is pulling all Question # and Questions from the SharePoint site, but I cannot bind the drop down box (yes/no) to any sort of local data source in order to record the information. Essentially what I have is a dynamically generated form which pulls questions off a SharePoint and a user will answer Yes or No for each question. I cannot associate the Yes/No drop down with anything because it resides within a Repeating section... Thanks for any help!

• How can I use data binding in WPF to create a new user control for each element in a list?

  - by Joel

  I have a list of objects. For each item in the list, I want to create a new user control bound to that item. From what I've read, doing this programmatically is bad practice with WPF (as well as less than straightforward), so I should use data binding as a solution instead. The problem is, I can't figure out how to do this. I don't know the contents of the list (just the type) at compile-time, so I can't create and bind with XAML for each element. Google and MSDN don't seem to have any answers, so maybe I'm thinking about this the wrong way? What do I need to do? Thanks

• Client authentication with RubyLDAP ldap

  - by Marcelo de Moraes Serpa

  Hello all, I'm trying to implement a feature that uses LDAP over SSL (SSL, not TLS), it needs to connect to a SSL-enabled LDAP server (i.e OpenLDAP), bind and then do any additional queries. It also needs to support client-authentication, and this is where things get tricky: The client is a web application written in Ruby, and we are using RubyLDAP (so far we have used it for non-SSL ldap stuff with great success). My question is: Is there a way to load a client certificate and send its data over the wire to the LDAP server when doing a LDAP::SSLConn? I haven't found anything obvious on the API docs (http://ruby-ldap.sourceforge.net/rdoc/) nor while googling around. I know I that I can prevent the server from asking for a certificate by putting the following on slapd.conf (OpenLDAP): TLSVerifyClient never However, this is not an option here. Thanks, Marcelo.

• Multi Select Checkbox using ListView

  - by Parsa

  I have a CheckBox in the header of ListView. I write a code to select all Checkboxes in ItemTemplate automatically when the user select the checkBox in the header of ListView. This code is useful, when you bind your ListView in DataPager_PreRender. protected void DataPager1_PreRender(object sender, EventArgs e) { //get the user id of the current user Guid userGuid = (Guid)Membership.GetUser().ProviderUserKey; ListView1.DataSource = MyClass.MyStaticMethod(userGuid.ToString()); ListView1.DataBind(); } protected void ListView1_ItemCreated(object sender, ListViewItemEventArgs e) { //Find the checkBox in each Row CheckBox checkBoxRow = e.Item.FindControl("CheckBoxRow") as CheckBox; //Assign the value of checkBoxHeader to the checkBoxRow checkBoxRow.Checked = CheckBoxHeader.Checked; } protected void ListView1_PagePropertiesChanged(object sender, EventArgs e) { // assign false value to the CheckBoxHeader when user click on the DataPager // so if checkboxheader is true in the page 1, when user select Page 2,this check box will be false // therefore all checkbox rows will be false in the new page. if (CheckBoxHeader.Checked == true) CheckBoxHeader.Checked = false; }

• UDP Socket Client in .NET

  - by Betamoo

  I use UDP Sokckts in my client application. Here are some code snippets: SendIP = new IPEndPoint(IPAddress.Parse(IP), port); ReceiveIP = (EndPoint)(new IPEndPoint(IPAddress.Any, 0)); socket = new Socket( AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp); socket.Bind(ReceiveIP); And to Receive (while(true)): byte[] data = new byte[BUFFERSIZE]; int receivedDataLength = socket.ReceiveFrom(data, ref ReceiveIP); string s= Encoding.ASCII.GetString(data, 0, receivedDataLength); I am doing an infinite while on the receive, there are other things to be done in the while, even if nothing is received.. I want to check if there are actually available data then receive else do not wait.. (Note the current receive method waits until the server sends a message)

  - by Bjarne

  I'm trying to bind a Viewbox to Canvas that is created dynamically like so: <ListBox.ItemTemplate> <DataTemplate> <DockPanel> <Viewbox> <ContentPresenter Content="{Binding Canvas}"/> </Viewbox> </DockPanel> </DataTemplate> </ListBox.ItemTemplate> This works fine as long as the Canvas doesn't have any children, but as soon at the Canvas has children it's not shown. What am I missing here?

• How to use Dependency Injection with ASP.NET

  - by Schneider

  I am trying to work out a way to use Dependency Injection with ASP.NET controls. I have got lots of controls that create repositories directly, and use those to access and bind to data etc. I am looking for a pattern where I can pass repositories to the controls externally (IoC), so my controls remain unaware of how repositories are constructed and where they come from etc. I would prefer not to have a dependency on the IoC container from my controls, therefore I just want to be able to construct the controls with constructor or property injection. (And just to complicate things, these controls are being constructed and placed on the page by a CMS at runtime!) Any thoughts?

• Multilingual support using gettext with codeigniter, best practice?

  - by tobefound

  I know how to create .po files and how to generate .mo files and then use them for translation on my Codeigniter powered site. However, I'm not quite sure on how to change language from the site GUI. I want to stick to codeigniter's default url calling schema: www.domain.com/controllername/method/param1/param2. Calling the server like this is a no-brainer: www.domain.com/controllername?lang=en Doing that for every controller using the default url schema, requires me to implement the same method in every controller, just to pass the lang parameter to the setlocale() function and then bind to my .po domain name. Feels awkward... ANy ideas how you guys work with gettext in codeigniter? And yes, I do want to work with gettext.

• What is a good pattern for binding a collection of objects coming from WCF, in Silverlight?

  - by Krishna

  Hi there, I've got a question about a Silverlight WCF Databinding pattern: There are many examples about how to bind data using {Binding} expressions in XAML, how to make async calls to a WCF service, set the DataContext property of a element in the UI, how to use ObservableCollections and INotifyPropertyChanged, INotifyCollectionChanged and so on. Background: I'm using the MVVM pattern, and have a Silverlight ItemsControl, whose ItemsSource is set to an ObservableCollection property on my ViewModel object. My view is of course the XAML which has the {Binding}. Say the model object is called 'Metric'. My ViewModel periodically makes calls to a WCF service that returns ObservableCollection. MetricInfo is the data transfer object (DTO). My question is two-fold: Is there any way to avoid copying each property of MetricInfo to the model class - Metric? When the WCF calls completes, is there any way to make sure I sync the items which are in both my local ObservableCollection and the result of the WCF call - without having to first clear out all the items in the local collection and then add all the ones from the WCF call result? thanks, Krishna

• Accessing and binding events to an ASP.NET Grid view using Jquery

  - by Sayem Ahmed

  I have an ASP page which displays a text box when it loads. It takes an input number, send it to the server through post back, and then displays some record in a grid view. After a number is input into the box, the server fetches some data from a database and add records to the grid view. It also contains a link column, whose URL is set to "#", so that the page isn't redirected when it is clicked. Now I want to bind a jquery "click" event to that link. How can I do that ? I have tried that to do myself but failed, because it is not available when the DOM is loaded (since it only contains rows when a number is input through the box), and is being modified through ASP.NET Ajax post back.

• Trying to debug a symfony app showing the list of all the functions called, debug_backtrace() doesn'

  - by user248959

  Hi, im trying to debug a symfony app. I've added a debug_backtrace() calling to this function below. It outputs a list of functions called, but the save() function (that is just before the debug_backtrace() calling) is not that list.. why? any other way to debug that shows more things, in this case the save() calling ? protected function processForm(sfWebRequest $request, sfForm $form) { $form->bind($request->getParameter($form->getName())); if ($form->isValid()) { $sf_guard_user = $form->save(); var_dump(debug_backtrace()); die("fsdgsgsdf"); $this->redirect('guardausuario/edit?id='.$sf_guard_user- >getId()); } } Regards Javi

• Can you update/add records in SQL using a datagridview and LINQ to SQL

  - by Jordan S

  Is it possible to bind a DataGridView to a LINQ to SQL class so that when I make changes to the records in the datagridview it automatically updates the SQL database? I have tried binding the data like this but if I make changes to the data in the datagrid view they do not actually affect the data in the database... BOMClassesDataContext DB = new BOMClassesDataContext(); var mfrs = from m in DB.Manufacturers select m; BindingSource bs = new BindingSource(); bs.DataSource = mfrs; dataGridView1.DataSource = bs;

• WPF TreeView binding to a simple object

  I have a simple object as such: public class Info { public string Name {get; set;} public int Count {get; set;} public DateTime TimeStamp {get; set;} } I want to bind a collection of these objects to a WPF TreeView and have the properties on the Info objects show up as sub TreeViewItems, like so: Item 1 Name: Bill Count: 3 TimeStamp: 12/05/2010 09:06:00 AM Item 2 Name: Chris Count: 22 TimeStamp: 11/05/2010 11:34:00 AM Item 3 Name: Toby Count: 1 TimeStamp: 09/05/2010 05:55:00 PM How can I achieve this through XAML?

• (partial apply str) and apply-str in clojure's ->

  - by Jason Baker

  If I do the following: user=> (-> ["1" "2"] (partial apply str)) #<core$partial__5034$fn__5040 clojure.core$partial__5034$fn__5040@d4dd758> ...I get a partial function back. However, if I bind it to a variable: user=> (def apply-str (partial apply str)) #'user/apply-str user=> (-> ["1" "2" "3"] apply-str) "123" ...the code works as I intended it. I would assume that they are the same thing, but apparently that isn't the case. Can someone explain why this is to me?

• Explanation of JAXB error: Invalid byte 1 of 1-byte UTF-8 sequence

  - by Marcus

  We're parsing an XML document using JAXB and get this error: [org.xml.sax.SAXParseException: Invalid byte 1 of 1-byte UTF-8 sequence.] at javax.xml.bind.helpers.AbstractUnmarshallerImpl.createUnmarshalException(AbstractUnmarshallerImpl.java:315) What exactly does this mean and how can we resolve this?? We are executing the code as: jaxbContext = JAXBContext.newInstance(Results.class); Unmarshaller unmarshaller = jaxbContext.createUnmarshaller(); unmarshaller.setSchema(getSchema()); results = (Results) unmarshaller.unmarshal(new FileInputStream(inputFile)); Update Issue appears to be due to this "funny" character in the XML file: ¿ Why would this cause such a problem??

• NHibernate transactions randomly not rolled back

  - by cbp

  I have a suite of integration tests that run inside transactions. Sometimes it seems that NHibernate transactions are not being correctly rolled back. I can't work out what causes this. Here is a slightly simplified overview of the base class that these integration test fixtures run with: public class IntegrationTestFixture { private TransactionScope _transactionScope; private ConnectionScope _connectionScope; [TestFixtureSetUp] public virtual void TestFixtureSetUp() { var session = NHibernateSessionManager.SessionFactory.OpenSession(); CallSessionContext.Bind(session); _connectionScope = new ConnectionScope(); _transactionScope = new TransactionScope(); } [TestFixtureTearDown] public virtual void TestFixtureTearDown() { _transactionScope.Dispose(); _connectionScope.Dispose(); var session = CurrentSessionContext.Unbind(SessionFactory); session.Close(); session.Dispose(); } } A call to the TransactionScope's commit method is never made, therefore how is it possible that data still ends up in the database?

• Maximum page fetch with maximum bandwith

  - by Ehsan

  Hi I want to create an application like a spider I've implement fetching page as the following code in multi-thread application but there is two problem 1) I want to use my maximum bandwidth to send/receive request, how should I config my request to do so (Like Download Accelerator application and the like) cause I heard the normal application will use 66% of the available bandwidth. 2) I don't know what exactly HttpWebRequest.KeepAlive do, but as its name implies I think i can create a connection to a website and without closing the connection sending another request to that web site using existing connection. does it boost performance or Im wrong ?? public PageFetchResult Fetch() { PageFetchResult fetchResult = new PageFetchResult(); try { HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create(URLAddress); HttpWebResponse resp = (HttpWebResponse)req.GetResponse(); Uri requestedURI = new Uri(URLAddress); Uri responseURI = resp.ResponseUri; string resultHTML = ""; byte[] reqHTML = ResponseAsBytes(resp); if (!string.IsNullOrEmpty(FetchingEncoding)) resultHTML = Encoding.GetEncoding(FetchingEncoding).GetString(reqHTML); else if (!string.IsNullOrEmpty(resp.CharacterSet)) resultHTML = Encoding.GetEncoding(resp.CharacterSet).GetString(reqHTML); req.Abort(); resp.Close(); fetchResult.IsOK = true; fetchResult.ResultHTML = resultHTML; } catch (Exception ex) { fetchResult.IsOK = false; fetchResult.ErrorMessage = ex.Message; } return fetchResult; }

• Rebinding jQuery qtip tooltip on images in bxcarousel

  - by skerit

  I'm using bxcarousel to show a bunch of images. Each image has a tooltip, which I display using qtip. This works fine for the first round, but when the images come round a second time the tooltips don't show anymore (because bxcarousel removes an element that slides out and puts it back at the end) An example of the carousel can be found here: http://www.kipdola.be/carousel/carousel.html This is the code used to bind the events (maybe it needs a "live" function somewhere?) // Create the tooltips only on document load $(document).ready(function() { // Use the each() method to gain access to each elements attributes $('#shopcarousel a[rel]').each(function() { $(this).qtip(

• How to implement JQuery easing into this window scroll movement function?

  - by Mohammad

  With this code I've been able to capture the mousewheel movement and apply it to the horizontal scroll bars instead of the vertical default. $('html').bind('mousewheel', function(event, delta) { window.parent.scrollBy(-120 * delta, 0); return false; }); Is there any way that I could add this jQuery easing animation to the scroll movement? jQuery.extend( jQuery.easing, { easeInOutBack: function (x, t, b, c, d, s) { if (s == undefined) s = 1.70158; if ((t/=d/2) < 1) return c/2*(t*t*(((s*=(1.525))+1)*t - s)) + b; return c/2*((t-=2)*t*(((s*=(1.525))+1)*t + s) + 2) + b; } }); Thank you so much in advance!

• How can I keep a WPF Image from blocking if the ImageSource references an unreachable Url?

  - by Corey O'Brien

  I'm writing a WPF application and trying to bind an image to my view model with the following XAML: <Image Source="{Binding Author.IconUrl, IsAsync=True}" /> The problem is that the image URLs are defined by users and can often refer to images hosted on intranet web servers. When the WPF application is run remotely, it locks up while trying to resolve the images that are now unreachable. I thought the "IsAsync" binding property would cause the load to happen in the background, but it appears that the DNS resolution may still happen in the main thread? What can I do to keep my app from locking, even if the images are unreachable? Thanks, Corey

• Strange behavior in DockPanel

  - by plotnick

  I don't understand, I have a toolbar with buttons bind to custom commands. Also I have an expandable control docked to the left of window - kinda NavPanel. (Devcomponents' NavigationPane to be exact) Now, everytime when it's collapsed or expanded, buttons in the toolbar become disabled and stay like that till the focus changes. Of course, it's simple to change the focus inside Collapsed and Expanded events, but unfortunately it works only in the first and ignores the second one and all buttons stay disabled. It seems that it something to do with CommandTarget which I haven't define nowhere. Maybe I should? Any ideas?

• Is Annotation in Javascript? If not, how to switch between debug/productive modes in declarative way

  - by Michael Mao

  Hi all: This is but a curious question. I cannot find any useful links from Google so it might be better to ask the gurus here. The point is: is there a way to make "annotation" in javascript source code so that all code snippets for testing purpose can be 'filtered out' when project is deployed from test field into the real environment? I know in Java, C# or some other languages, you can assign an annotation just above the function name, such as : // it is good to remove the annoying warning messages @SuppressWarnings("unchecked") public class Tester extends TestingPackage { ... } Basically I've got a lot of testing code that prints out something into FireBug console. I don't wanna manually "comment out" them because the guy that is going to maintain the code might not be aware of all the testing functions, so he/she might just miss one function and the whole thing can be brought down to its knees. One other thing, we might use a minimizer to "shrink" the source code into "human unreadable" code and boost up performance (just like jQuery.min), so trying to match testing section out of the mess is not possible for plain human eyes in the future. Any suggestion is much appreciated.
