• Javascript: Onload if checkbox is checked, change li class

  - by BoDiE2003

  I have this code on javascript side: function changeSelectionStyle(id) { if(document.getElementById(id).className != 'yes'){ document.getElementById(id).className = 'yes'; } else{document.getElementById(id).className = '';} } And this on html: <ul> <li id="selectedAuthorities-4_1li" class=""> <input type="checkbox" id="selectedAuthorities-4_1" name="selectedAuthorities" value="ROLE_ADD_COMMENT_TO_CV" checked="checked" onload="changeSelectionStyle(this.id + 'li');" onclick="changeSelectionStyle(this.id + 'li'); checkFatherSelection(this.id);"> <a href="#" onclick="document.getElementById('selectedAuthorities-4_1').click(); return false;"> Agregar comentario <samp><b></b>Permite agregar comentario en el detalle.</samp> </a> </li> Well what I cant get work is when the checkbox is selected, on load, the JS should check it, and assign class="yes" to the li, here: <li id="selectedAuthorities-4_1li" class=""> What should I add to my original JS function to make that possible. Note that li ids are not static, they are dynamic, the html li id is generated.

• .Net Entity Framework & POCO ... querying full table problem

  - by Chris Klepeis

  I'm attempting to implement a repository pattern with my poco objects auto generated from my edmx. In my repository class, I have: IObjectSet<E> _objectSet; private IObjectSet<E> objectSet { get { if (_objectSet == null) { _objectSet = this._context.CreateObjectSet<E>(); } return _objectSet; } } public IQueryable<E> GetQuery(Func<E, bool> where) { return objectSet.Where(where).AsQueryable<E>(); } public IList<E> SelectAll(Func<E, bool> where) { return GetQuery(where).ToList(); } Where E is the one of my POCO classes. When I trace the database and run this: IList<Contact> c = contactRepository.SelectAll(r => r.emailAddress == "[email protected]"); It shows up in the sql trace as a select for everything in my Contact table. Where am I going wrong here? Is there a better way to do this? Does an objectset not lazy load... so it omitted the where clause? This is the article I read which said to use objectSet's... since with POCO, I do not have EntityObject's to pass into "E" http://devtalk.dk/CommentView,guid,b5d9cad2-e155-423b-b66f-7ec287c5cb06.aspx

• jQuery - select onchange to slide in / slide out div or form

  - by slayaz

  Hi, I am trying to enhance a form, by showing only relevant fields depending on initial selection via a form select field. It is an order form for 3 products and all 3 products have unique properties. My idea was to hide all the content in divs, then reveal the relevant div when the product is selected. I have found some solutions that show / hide a div, but none with any animation. It doesn't have to be a slide but just something nice! The alternative is instead of revealing a div, would be to load a seperate form, but this seems unnecessary. I am not sure whether i need a plug in, as I am pretty new to jquery. What i have in the html is: <style type="text/css"> .hide { display:none; } <select> <option value="" >Please select product below</option> <option value="pro1">Product 1</option> <option value="pro2">Product 2</option> </select> <div id="pro1" class="hide" >Product 1</div> <div id="pro2" class="hide" >Product 2</div> Many thanks in advance

• Targetting x86 vs AnyCPU when building for 64 bit window OSes

  - by Mr Roys

  I have an existing C# application written for .NET 2.0 and targetting AnyCPU at the moment. It currently references some third party .NET DLLs which I don't have the source for (and I'm not sure if they were built for x86, x64 or AnyCPU). If I want to run my application specifically on a 64 bit Windows OS, which platform should I target in order for my app to run without errors? My understanding at the moment is to target: x86: If at least one third party .NET dll is built for x86 or use p/Invoke to interface with Win32 DLLs. Application will run in 32 bit mode on both 32 bit and 64 bit OSes. x64: If all third party .NET dlls are already built for x64 or AnyCPU. Application will only run in 64 bit OSes. AnyCPU: If all third party .NET dlls are already built for AnyCPU. Application will run in 32 bit mode on 32 bit OSes and 64 bit on 64 bit OSes. Also, am I right to believe that while targetting AnyCPU will generate no errors when building a application referencing third party x86 .NET DLLs, the application will throw a runtime exception when it tries to load these DLLs when it runs on a 64 bit OS. Hence, as long as one of my third party DLLs is doing p/Invoke or are x86, I can only target x86 for this application?

• Cast object to interface when created via reflection

  - by Al

  I'm trying some stuff out in Android and I'm stuck at when trying to cast a class in another .apk to my interface. I have the interface and various classes in other .apks that implement that interface. I find the other classes using PackageManager's query methods and use Application#createPackageContext() to get the classloader for that context. I then load the class, create a new instance and try to cast it to my interface, which I know it definitely implements. When I try to cast, it throws a class cast exception. I tried various things like loading the interface first, using Class#asSubclass, etc, none of which work. Class#getInterfaces() shows the interface is implemented. My code is below: PackageManager pm = getPackageManager(); List<ResolveInfo> lr = pm.queryIntentServices(new Intent("com.example.some.action"), 0); ArrayList<MyInterface> list = new ArrayList<MyInterface>(); for (ResolveInfo r : lr) { try { Context c = getApplication().createPackageContext(r.serviceInfo.packageName, Context.CONTEXT_IGNORE_SECURITY | Context.CONTEXT_INCLUDE_CODE); ClassLoader cl = c.getClassLoader(); String className = r.serviceInfo.name; if (className != null) { try { Class<?> cls = cl.loadClass(className); Object o = cls.newInstance(); if (o instanceof MyInterface) { //fails list.add((MyInterface) o); } } catch (ClassNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } // some exceptions removed for readability } } catch (NameNotFoundException e1) { e1.printStackTrace(); }

• How to get pixel information inside a fragment shader?

  - by user697111

  In my fragment shader I can load a texture, then do this: uniform sampler2D tex; void main(void) { vec4 color = texture2D(tex, gl_TexCoord[0].st); gl_FragColor = color; } That sets the current pixel to color value of texture. I can modify these, etc and it works well. But a few questions. How do I tell "which" pixel I am? For example, say I want to set pixel 100,100 (x,y) to red. Everything else to black. How do I do a : "if currentSelf.Position() == (100,100); then color=red; else color=black?" ? I know how to set colors, but how do I get "my" location? Secondly, how do I get values from a neighbor pixel? I tried this: vec4 nextColor = texture2D(tex, gl_TexCoord[1].st); But not clear what it is returning? if I'm pixel 100,100; how do I get the values from 101,100 or 100,101?

• Exception while hosting a WCF Service in a DependencyInjection Module ?

  - by Maciek

  Hello, I've written a small just-for-fun console project using Ninject, I'm pasting some of the code below just so that you get the idea : Program.cs using System; using Ninject; using Ninjectionn.Modules; // My namespace for my modules namespace Ninjections { class Program { static void Main(string[] args) { IKernel kernel = new StandardKernel(); kernel.Load<ServicesHostModule>(); Console.ReadKey(); } } } ServicesHostModule.cs using System; using System.ServiceModel; using Ninject; using Ninject.Modules; namespace Ninjections.Modules { public class ServicesHostModule : INinjectModule { #region INinjectModule Members public string Name { get { return "ServicesHost"; }} public void OnLoad(IKernel kernel) { if(m_host != null) m_host.Close(); else m_host = new ServiceHost(typeof(WCFTestService)); m_host.Open(); // (!) EXCEPTION HERE } public void OnUnLoad(IKernel kernel) { m_host.Close(); } #endregion } } ITestWCFService.cs using System.ServiceModel; namespace Ninjections.Modules { [ServiceContract] public interface ITestWCFService { [OperationContract] string GetString1(); [OperationContract] string GetString2(); } } An auto-generated App.config is in the ServicesHostModule project. I've "added" an existing item (the app config) as link in the main project. Q: at the m_host.Open(); line, an InvalidOperationException occurs. The message says : "Service "Ninjections.Modules.TestWCFService" has zero application endopints. What's wrong?

• Is there a way to increase performance on my simple textfilter?

  - by djerry

  Hey guys, I'm writing a filter that will pick out items. I have a list of Objects. The objects contain a number, name and some other irrelevant items. At the moment, the list contains 200 items. When typing in a textbox, i'm looking if the string matches a part of the number/name of the objects in the list. If so, add them to the listbox. Here's the code for my textbox textchanged event : private void txtTelnumber_TextChanged(object sender, TextChangedEventArgs e) { lstOverview.Items.Clear(); string data = ""; foreach (ucTelListItem telList in _allUsers) { data = telList.User.H323 + telList.user.E164; if (data.Contains(txtTelnumber.Text)) lstOverview.Items.Add(telList); } } I sometimes see a little delay when entering a character, especially when i go from 4 records to 200 records (so when i had a filter and 4 records matched, and i backspace and the whole list appears again). My list is a list of usercontrols, cause i found it takes less time to load the usercontrols from a list, then to have to initialize a new usercontrol each time. Can i do something about the code, or is it just adding the usercontrol the listbox that causes the small delay (small delay = <1 sec)? Thanks in advance.

• Using memory-based cache together with conventional cache

  - by Industrial

  Hi! Here's the deal. We would have taken the complete static html road to solve performance issues, but since the site will be partially dynamic, this won't work out for us. What we have thought of instead is using memcache + eAccelerator to speed up PHP and take care of caching for the most used data. Here's our two approaches that we have thought of right now: Using memcache on all<< major queries and leaving it alone to do what it does best. Usinc memcache for most commonly retrieved data, and combining with a standard harddrive-stored cache for further usage. The major advantage of only using memcache is of course the performance, but as users increases, the memory usage gets heavy. Combining the two sounds like a more natural approach to us, even though the theoretical compromize in performance. Memcached appears to have some replication features available as well, which may come handy when it's time to increase the nodes. What approach should we use? - Is it stupid to compromize and combine the two methods? Should we insted be focusing on utilizing memcache and instead focusing on upgrading the memory as the load increases with the number of users? Thanks a lot!

• iphone: cross platform references and referencing external framework resources

  - by dan

  hi there working on an iphone app and separate framework. the separate framework is for an API that i'm building for use in multiple future apps. this api now needs to reference resources (images). what i would like to do is keep the resources WITH the API framework as local set of resources. i followed the instructions from http://www.clintharris.net/2009/iphone-app-shared-libraries/ to setup my app's project to use the headers from the separate API framework. what i can't seem to figure out is how to automatically load the framework's resources into the app's xcode environment so they can be linked in at app compile time. sure, i can drag the resources across from the framework into the main app's set of resources. but that seems kinda ugly and another step that possibly can be automated (??) anyone know of a better way? it would be great if any changes from the framework would be automatically available in the main app (due to the project 'link-age'). thanks for any help/tips/suggestions...

• How to manage data access / preloading efficiently using web services in C# ?

  - by Amadeus45

  Hello all, Ok, this is very "generic" question. We currently have a SQL Server database for which we need to develop an application in ASP.NET with will contain all the business logic in C# Web Services. The thing is that, architecturally speaking, I'm not sure how to design the web service and the data management. There are many things to consider : We need have very rapid access to data. Right now, we have over a million "sales" and "purchases" record from which we need to often calculate and load the current stock for a given day according to a serie of parameter. I'm not sure how we should preload the data and keep the data in the Web Service. Doing a stock calculation within a SQL query will be very lengthy. They currently have a stock calculation application that preloads all sales and purchases for the day and afterwards calculate the stock on the code-side. We want to develop powerful reporting tools. We want to implement a "pivot table" but not sure how to implement it and have good performances. For the reasons above, I'm not sure how to design the data model. Anybody can give me any guidelines on how to start, or from their personnal experiences (what have you done in the past ?) I'm not sure if it's possible to make a bounty even though the question is new (I'd put 300 rep on it, since I really need something). If you know how, let me know. Thanks

• Need to calculate rotation-vector from Sensor.TYPE_ORIENTATION data

  - by Sponge

  I need to calculate a rotation vector out of the data i get from Sensor.TYPE_ORIENTATION. The sensor data is defined like this: the values have to be recalculated to become a correct 3d position: values[0]: Azimuth, angle between the magnetic north direction and the Y axis, around the Z axis (0 to 359). 0=North, 90=East, 180=South, 270=West values[1]: Pitch, rotation around X axis (-180 to 180), with positive values when the z-axis moves toward the y-axis. values[2]: Roll, rotation around Y axis (-90 to 90), with positive values when the x-axis moves away from the z-axis I need all three values like the Z axis value (from 0 to 360 degree). I tried a lot but cant figure out how to do this :/ i also tried to use Sensor.TYPE_ACCELEROMETER and Sensor.TYPE_MAGNETIC_FIELD to calculate this 3d vector on my own. here is the code: final float[] inR = new float[16]; // load inR matrix from current sensor data: SensorManager.getRotationMatrix(inR, null, gravityValues, geomagneticValues); float[] orientation = new float[3]; SensorManager.getOrientation(inR, orientation); mapMagAndAcclDataToVector(orientation); //here i do some *360 stuff orientetionChanged(orientation); //then the correct values are passed (in theorie) But this didn't work and i think it is much to complicated. So i bet there is a simple solution how to recalc the values of ensor.TYPE_ORIENTATION to make them a 3d rotation vector, but i just dont know how to do it. If you know the answer please tell me.

• HTML file: add annotations through IHTMLDocument

  - by peterchen

  I need to add "annotations" to existing HTML documents - best in the form of string property values I can read & write by name. Apparently (to me), meta elements in the header seem to be the common way - i.e. adding/modifying elements like <head> <meta name="unique-id_property-name" content="property-value"/> ... </head> Question 1: Ist that "acceptable" / ok, or is there a better way to add meta data? I have a little previous experience with getting/mut(il)ating HTML contents through the document in an web browser control. For this task, I've already loaded the HTML document into a HTMLDocument object, but I'm not sure how to go on: // what I have IHTMLDocument2Ptr doc; doc.CreateInstance(__uuidof(HTMLDocument)); IPersistFile pf = doc; pf->Load(fileName, STGM_READ); // everything ok until here Questions 2: Should I be using anything else than HTMLDocument? Questions 3..N: How do I get the head element? How do I get the value of a meta element with a given name? How do I set the value of a meta element (adding the item if and only if it doesn't exist yet)? doc->all returns a collection of all tags, which I can enumerate even though count returns 0. I could scan that for head, then scan that for all meta where the name starts with a certain string, etc. - but this feels very clumsy.

• Why does my App.Config codebase not help .NET locate my assembly?

  - by pkolodziej

  I have the following client application and its corresponding config file: namespace Chapter9 { class Program { static void Main(string[] args) { AppDomain.CurrentDomain.ExecuteAssembly("AssemblyPrivate.exe"); } } } <configuration> <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <dependentAssembly> <codeBase href="file://C:\Users\djpiter\Documents\Visual Studio 2008\Projects\70536\AssemblyPrivate\bin\Debug\AssemblyPrivate.exe"/> </dependentAssembly> </assemblyBinding> </runtime> </configuration> The AssemblyPrivate.exe does not have a public key, nor is it located in the GAC. As far as I know, the runtime should parse the app.config file before looking for an assembly in the client app directory. The unhandled exception (wrapped for readability) is: Unhandled Exception: System.IO.FileNotFoundException: Could not load file or assembly 'file:///C:\Users\djpiter\Documents\Visual Studio 2008\Projects\70536\Chapter9\bin\Debug\AssemblyPrivate.exe' or one of its dependencies. The system cannot find the file specified. Why it is not working? I need to use dynamic binding (not static). Kind Regards, PK

• Problem importing Oracle .dmp file

  - by BitFiddler

  So I have looked at all the suggested ways of importing .dmp files and non of them seem to answer this question: where does the data go once you import it? Context: I created a user like so: SQL> create user IMPORTER identified by "12345"; SQL> grant connect, unlimited tablespace, resource to IMPORTER; I then ran the 'imp' command as follows: C:\>imp system/password FROMUSER=OVIEDOE TOUSER=IMPORTER file=c:\database1.dmp Now there were 9 .dmp files, after each one it asked me for the next one and then I received the message "Import terminated successfully with warnings." The warning was: Warning: the objects were exported by OVIEDOE, not by you import done in WE8MSWIN1252 character set and AL16UTF16 NCHAR character set export client uses WE8ISO8859P1 character set (possible charset conversion) IMP-00046: using FILESIZE value from export file of 2147483648 Now it says it was terminated successfully so my assumption (I am new to oracle so this may be wrong) is that the data was loaded. However, when I use SQL developer to connect to the database and look under the 'tables' node under the IMPORTER user, there is nothing there. What is going on? Did the data load? If so, where can I find it?

• Linq to sql Repository pattern , Some doubts

  I am using repository pattern with linq to sql, I am using a repository class per table. I want to know , am i doing at good/standard way, ContactRepository Contact GetByID() Contact GetAll() COntactTagRepository List<ContactTag> Get(long contactID) List<ContactTag> GetAll() List<ContactTagDetail> GetAllDetails() class ContactTagDetail { public Contact Contact {get;set;} public ContactTag COntactTag {get;set;} } When i need a contact i call method in contactrepository, same for contacttag but when i need contact and tags together i call GetDetais() in ContactTag repository its not returning the COntactTag entity generated by the orm insted its returning ContactTagDetail entity conatining both COntact and COntactTag generated by the orm, i know i can simple call GetAll in COntactTag repository and can access Contact.ContactTag but as its linq to sql it will there is no option to Deferred Load in query level, so whenever i need a entity with a related entity i create a projection class Another doubt is where i really need to right the method i can do it in both contact & ContactTag repostitory like In contact repository GetALlWithTags() or something but i am doing it in in COntactTag repository Whats your suggestions ?

• Best practices, PHP, tracking millions of impressions per day.

  - by John

  What do I have to do to make 20k mysql inserts per second possible (during peak hours around 1k/sec during slower times)? I've been doing some research and I've seen the "INSERT DELAYED" suggestion, writing to a flat file, "fopen(file,'a')", and then running a chron job to dump the "needed" data into mysql, etc. I've also heard you need multiple servers and "load balancers" which I've never heard of, to make something like this work. I've also been looking at these "cloud server" thing-a-ma-jigs, and their automatic scalability, but not sure about what's actually scalable. The application is just a tracker script, so if I have 100 websites that get 3 million page loads a day, there will be around 300 million inserts a day. The data will be ran through a script that will run every 15-30 minutes which will normalize the data and insert it into another mysql table. How do the big dogs do it? How do the little dogs do it? I can't afford a huge server anymore so any intuitive ways, if there are multiple ways of going at it, you smart people can think of.. please let me know :)

• How to use google maps API with multiple markers on the same map

  - by Maen

  So, i have the following script to use the google maps API, its all fine, but i need to create a map that has more than one Marker (the balloon shaped icon pointing to something) and i need each of those markers to point on a different area of the map (i.e. different coordinates), how can i do it? <script type="text/javascript"> function load() { var map = new GMap2(document.getElementById("map")); var marker = new GMarker(new GLatLng(<%=coordinates%>)); var html="<img src='simplemap_logo.jpg' width='20' height='20'/> " + "<%=maptitle%><br/>" + "<%=text%>"; map.setCenter(new GLatLng(<%=coordinates%>), <%=zoom%>) map.setMapType(G_HYBRID_MAP); map.addOverlay(marker); map.addControl(new GLargeMapControl()); map.addControl(new GScaleControl()); map.addControl(new GMapTypeControl()); marker.openInfoWindowHtml(html); } //]]> </script> One more question, if i pass the Script text as a variable, lets say something like: <script type="text/javascript"> <%=ScriptText%> </script> and my <%=ScriptText% will be a string which i will build and assign its value to a Friend or Public variable called ScriptText, will it still run and work properly? (i am doing this to make my script dynamic and different based on how i build it as a STRING, due to my illiteracy in javascripting ;P)

• jQuery-driven app. won't work without alert()

  - by webjawns.com

  I have seen a lot of articles on this, but none dealing with jQuery, so here I go... I am implementing a version of a script from http://javascript-array.com/scripts/jquery_simple_drop_down_menu/ into an existing application; however, I cannot get it to work without adding alert('msg...') as the first method within the $(document).ready() call. This has nothing to do with load time... no matter how long I wait, the menu does not work. Add alert(), however, and it works like a charm. var timeout = 500; var closetimer = 0; var ddmenuitem = 0; function jsddm_open() { jsddm_canceltimer(); jsddm_close(); ddmenuitem = $(this).find('ul').css('visibility', 'visible');} function jsddm_close() { if(ddmenuitem) ddmenuitem.css('visibility', 'hidden');} function jsddm_timer() { closetimer = window.setTimeout(jsddm_close, timeout);} function jsddm_canceltimer() { if(closetimer) { window.clearTimeout(closetimer); closetimer = null;}} $(document).ready(function() { $('#jsddm > li').bind('mouseover', jsddm_open) $('#jsddm > li').bind('mouseout', jsddm_timer)}); document.onclick = jsddm_close;

• strange run time error message from CIImage initWithContentsOfURL

  - by Adam

  When executing the following code I receive a run time error when the code executes the second line of code. The error (which shows up in the debugger) says: [NSButton initWithContentsOfURL:]: unrecognized selector sent to instance 0x100418e10. I don't understand this message, because it looks to me (based on my source code) like the initWithContentsOfURL message is being sent to the myImage instance (of the CIImage class) ... not NSButton. Any idea what is going on? If it matters ... this code is in the Application Controller class module of an Xcode project (a Cocoa application) -- within a method that is called when I click on a button on the application window. There is only the one button on the window ... // Step1: Load the JPG file into CIImage NSURL *myURL = [NSURL fileURLWithPath:@"/Users/Adam/Documents/Images/image7.jpg"]; CIImage *myImage = [myImage initWithContentsOfURL: myURL]; if (myImage = Nil) { NSLog(@"Creating myImage failed"); return; } else { NSLog(@"Created myImage successfully"); }

• Changing a url depending on what link chosen (HTML) no asp.

  - by Ozaki

  TLDR I need to change a javascript variable on the same page after clicking a link (can be from a different page) so that the getjson request pulls different data without having to duplicate on html pages. I am using some getJSON requests with Jquery, to make calls to populate my pages. I want to be able to (in plain HTML / javascript) when the user clicks say "link 1" or "link 2" to open the same page (say page.html) but change the get request url to "link 1" or "link 2". Page.html var url = ??; $.getJSON(url, function(data){} link 1 var url = host/link1 <a href="page.html">link1</a> link2 var url = host/link2 <a href="page.html">link2</a> So I call the same page but am able to populate it with different content. Purposely staying away from asp. Was thinking maybe of inserting the content into a div after page load so the url can be set or something along those lines. Any ideas how I might go about this?

• Why does Tex/Latex not speed up in subsequent runs?

  - by Debilski

  I really wonder, why even recent systems of Tex/Latex do not use any caching to speed up later runs. Every time that I fix a single comma*, calling Latex costs me about the same amount of time, because it needs to load and convert every single picture file. (* I know that even changing a tiny comma could affect the whole structure but of course, a well-written cache format could see the impact of that. Also, there might be situations where 100% correctness is not needed as long as it’s fast.) Is there something in the language of Tex which makes this complicated or impossible to accomplish or is it just that in the original implementation of Tex, there was no need for this (because it would have been slow anyway on those large computers)? But then on the other hand, why doesn’t this annoy other people so much that they’ve started a fork which has some sort of caching (or transparent conversion of Tex files to a format which is faster to parse)? Is there anything I can do to speed up subsequent runs of Latex? Except from putting all the stuff into chapterXX.tex files and then commenting them out?

• Who likes #regions in Visual Studio?

  - by Nicholas

  Personally I can't stand region tags, but clearly they have wide spread appeal for organizing code, so I want to test the temperature of the water for other MS developer's take on this idea. My personal feeling is that any sort of silly trick to simplify code only acts to encourage terrible coding behavior, like lack of cohesion, unclear intention and poor or incomplete coding standards. One programmer told me that code regions helped encourage coding standards by making it clear where another programmer should put his or her contributions. But, to be blunt, this sounds like a load of horse manure to me. If you have a standard, it is the programmer's job to understand what that standard is... you should't need to define it in every single class file. And, nothing is more annoying than having all of your code collapsed when you open a file. I know that cntrl + M, L will open everything up, but then you have the hideous "hash region definition" open and closing lines to read. They're just irritating. My most stead fast coding philosophy is that all programmer should strive to create clear, concise and cohesive code. Region tags just serve to create noise and redundant intentions. Region tags would be moot in a well thought out and intentioned class. The only place they seem to make sense to me, is in automatically generated code, because you should never have to read that outside of personal curiosity.
