  • Replacing div html() by echoing PHP - how to?

    - by Jared
    Hello, I have a multiple product elements that get their class and ID from PHP: $product1["codename"] = "product-1"; $product1["short"] = "Great Product 1"; $product2["codename"] = "product-2"; $product2["short"] = "Great Product 2"; <div class="leftMenuProductButton" id="'. $product1["codename"].'" >'. $product1["short"].'</div> <div class="leftMenuProductButton" id="'. $product2["codename"].'" >'. $product2["short"].'</div> These display as: <div class="leftMenuProductButton" id="product-1" > Great Product 1</div> <div class="leftMenuProductButton" id="product-2" > Great Product 2</div> In the page, I have an element that I want to replace the HTML: <div id="productPopupTop"> //Replace this content </div> Using jquery, I have tried the following: $( '.leftMenuProductButton' ).hover ( function () { var swapNAME = $(this).attr("id"); //gets the ID, #product-1, #product-2 etc. This works. $("#productPopupTop").html(' <? echo $' + swapNAME + '["short"] ?>'); //This is supposed to get something like <? echo $product-1["short"] ?> This doesn't appear to work. }, function () { //this is just here for later }); If I try to do an alert('<? echo $' + swapNAME + '["short"] ?>'); it will literally display something like <? echo $product-1["short"] ?> Please note that both the Javascript and the PHP are externally linked in a PHP file (index.php <<< (js.js, products.php) QUESTION: How do I replace the HTML() of #productPopupTop with the ["short"] of a product? If I should use Ajax, how would I code this?

  • organizing unit test

    - by soulmerge
    I have found several conventions to housekeeping unit tests in a project and I'm not sure which approach would be suitable for our next PHP project. I am trying to find the best convention to encourage easy development and accessibility of the tests when reviewing the source code. I would be very interested in your experience/opinion regarding each: One folder for productive code, another for unit tests: This separates unit tests from the logic files of the project. This separation of concerns is as much a nuisance as it is an advantage: Someone looking into the source code of the project will - so I suppose - either browse the implementation or the unit tests (or more commonly: the implementation only). The advantage of unit tests being another viewpoint to your classes is lost - those two viewpoints are just too far apart IMO. Annotated test methods: Any modern unit testing framework I know allows developers to create dedicated test methods, annotating them (@test) and embedding them in the project code. The big drawback I see here is that the project files get cluttered. Even if these methods are separated using a comment header (like UNIT TESTS below this line) it just bloats the class unnecessarily. Test files within the same folders as the implementation files: Our file naming convention dictates that PHP files containing classes (one class per file) should end with .class.php. I could imagine that putting unit tests regarding a class file into another one ending on .test.php would render the tests much more present to other developers without tainting the class. Although it bloats the project folders, instead of the implementation files, this is my favorite so far, but I have my doubts: I would think others have come up with this already, and discarded this option for some reason (i.e. I have not seen a java project with the files Foo.java and FooTest.java within the same folder.) Maybe it's because java developers make heavier use of IDEs that allow them easier access to the tests, whereas in PHP no big editors have emerged (like eclipse for java) - many devs I know use vim/emacs or similar editors with little support for PHP development per se. What is your experience with any of these unit test placements? Do you have another convention I haven't listed here? Or am I just overrating unit test accessibility to reviewing developers?

  • SwingWorker exceptions lost even when using wrapper classes

    - by Ti Strga
    I've been struggling with the usability problem of SwingWorker eating any exceptions thrown in the background task, for example, described on this SO thread. That thread gives a nice description of the problem, but doesn't discuss recovering the original exception. The applet I've been handed needs to propagate the exception upwards. But I haven't been able to even catch it. I'm using the SimpleSwingWorker wrapper class from this blog entry specifically to try and address this issue. It's a fairly small class but I'll repost it at the end here just for reference. The calling code looks broadly like try { // lots of code here to prepare data, finishing with SpecialDataHelper helper = new SpecialDataHelper(...stuff...); helper.execute(); } catch (Throwable e) { // used "Throwable" here in desperation to try and get // anything at all to match, including unchecked exceptions // // no luck, this code is never ever used :-( } The wrappers: class SpecialDataHelper extends SimpleSwingWorker { public SpecialDataHelper (SpecialData sd) { this.stuff = etc etc etc; } public Void doInBackground() throws Exception { OurCodeThatThrowsACheckedException(this.stuff); return null; } protected void done() { // called only when successful // never reached if there's an error } } The feature of SimpleSwingWorker is that the actual SwingWorker's done()/get() methods are automatically called. This, in theory, rethrows any exceptions that happened in the background. In practice, nothing is ever caught, and I don't even know why. The SimpleSwingWorker class, for reference, and with nothing elided for brevity: import java.util.concurrent.ExecutionException; import javax.swing.SwingWorker; /** * A drop-in replacement for SwingWorker<Void,Void> but will not silently * swallow exceptions during background execution. * * Taken from http://jonathangiles.net/blog/?p=341 with thanks. */ public abstract class SimpleSwingWorker { private final SwingWorker<Void,Void> worker = new SwingWorker<Void,Void>() { @Override protected Void doInBackground() throws Exception { SimpleSwingWorker.this.doInBackground(); return null; } @Override protected void done() { // Exceptions are lost unless get() is called on the // originating thread. We do so here. try { get(); } catch (final InterruptedException ex) { throw new RuntimeException(ex); } catch (final ExecutionException ex) { throw new RuntimeException(ex.getCause()); } SimpleSwingWorker.this.done(); } }; public SimpleSwingWorker() {} protected abstract Void doInBackground() throws Exception; protected abstract void done(); public void execute() { worker.execute(); } }

  • Jquery question : maintain focus upon appending a row?

    - by PoppySeedsAndAppleJuice
    The function below checks whether the id entered is already in the database, and if it is, then it adds some html to the table. I'm not sure if it's directly related to my issue or not, but, essentially, a user will place the focus on the id input field and enters an id. Using ajax, it posts to a php script and returns data if rows are found and nothing if it doesn't. If the user then tabs over to the next input field (zipcode), or clicks in another input field, they essentially have to do so twice. The cursor "flashes" in the field briefly and then focuses out. I tried adding in a focus(), but the behavior didn't change. So, the html looks like this: <table id="tableSearchData" class="searchlist" style="width: 789px;"> <thead> <tr> <th>ID</th> <th>Zip Code</th> <th>Radius (in miles)</th> </tr> </thead> <tbody> <tr class="odd"> <!-- PROBLEM is described below --> <!-- User clicks in <input name="id[]"> and ID is checked --> <!-- User presses "tab" or clicks in <input name="zipcode[] (in the *same* row) and cursor flashes, then goes out of focus so that the user has to click in the field again --> <td class="center sorting_1"><input type="text" value="" name="id[]"></td> <td class="center"><input type="text" value="" name="zipcode[]"></td> <td class="center"><input type="text" value="" name="radius[]"></td> </tr> </tbody> </table> Here's the jquery function... Like I said, I'm not sure if it's directly related to the problem I'm having, but, thought I should include it because I suppose it's likely there is something happening there... $("#tableSearchData > tbody > tr > td > input[name=id[]]").focusout(function() { var row = $(this).closest("tr").get(0); var sData = $(this).serialize(); $.ajax({ type: "POST", url: "checkid.php", data: sData, success: function(html) { $(row).replaceWith(html); $(".preset").each(function() { $(this).attr("disabled", true); }); $(row).closest("input[name=zipcode[]]").focus(); } }); });

  • Can first descendent be selected directly?

    - by Ben Huh
    I am currently using find() and first() method to select the first descendent element from each of the <div> elements that contains the parent class. But I find this quite cumbersome since find() method would produce a set of matched elements before the first element is being picked. The following is the skeleton of my code: HTML <div class=parent> <ul> <li>random characters</li> <li>random characters</li> <li>random characters</li> <li>random characters</li> </ul> </div> <div class=parent> <ul> <li>random characters</li> <li>random characters</li> <li>random characters</li> <li>random characters</li> </ul> </div> <div class=non-parent> <ul> <li>random characters</li> <li>random characters</li> <li>random characters</li> <li>random characters</li> </ul> </div> <div class=parent> <ul> <li>random characters</li> <li>random characters</li> <li>random characters</li> <li>random characters</li> </ul> </div> // .....the list continues Javascript $('.parent').each(function() { $(this).find('ul li').first().css('color', 'red'); // do other stuff within each loop }); I have seen people using $(".parent li:first") selector. But, because I am doing it in a loop, I am not sure how or whether if this could be done and would like some advice. Thanks.

  • How can I link two Java serialised objects back together?

    - by Kidburla
    Sometimes (quite a lot, actually) we get a situation in Java where two objects are pointing to the same thing. Now if we serialise these separately it is quite appropriate that the serialised forms have separate copies of the object as it should be possible to open one without the other. However if we now deserialise them both, we find that they are still separated. Is there any way to link them back together? Example follows. public class Example { private static class ContainerClass implements java.io.Serializable { private ReferencedClass obj; public ReferencedClass get() { return obj; } public void set(ReferencedClass obj) { this.obj = obj; } } private static class ReferencedClass implements java.io.Serializable { private int i = 0; public int get() { return i; } public void set(int i) { this.i = i; } } public static void main(String[] args) throws Exception { //Initialise the classes ContainerClass test1 = new ContainerClass(); ContainerClass test2 = new ContainerClass(); ReferencedClass ref = new ReferencedClass(); //Make both container class point to the same reference test1.set(ref); test2.set(ref); //This does what we expect: setting the integer in one (way of accessing the) referenced class sets it in the other one test1.get().set(1234); System.out.println(Integer.toString(test2.get().get())); //Now serialise the container classes java.io.ObjectOutputStream os = new java.io.ObjectOutputStream(new java.io.FileOutputStream("C:\\Users\\Public\\test1.ser")); os.writeObject(test1); os.close(); os = new java.io.ObjectOutputStream(new java.io.FileOutputStream("C:\\Users\\Public\\test2.ser")); os.writeObject(test2); os.close(); //And deserialise them java.io.ObjectInputStream is = new java.io.ObjectInputStream(new java.io.FileInputStream("C:\\Users\\Public\\test1.ser")); ContainerClass test3 = (ContainerClass)is.readObject(); is.close(); is = new java.io.ObjectInputStream(new java.io.FileInputStream("C:\\Users\\Public\\test2.ser")); ContainerClass test4 = (ContainerClass)is.readObject(); is.close(); //We expect the same thing as before, and would expect a result of 4321, but this doesn't happen as the referenced objects are now separate instances test3.get().set(4321); System.out.println(Integer.toString(test4.get().get())); } }

  • Returning different data types C#

    - by user1810659
    i have create a class library (DLL) with many different methods. and the return different types of data(string string[] double double[]). Therefore i have created one class i called CustomDataType for all the methods containing different data types so each method in the Library can return object of the custom class and this way be able to return multiple data types I have done it like this: public class CustomDataType { public double Value; public string Timestamp; public string Description; public string Unit; // special for GetparamterInfo public string OpcItemUrl; public string Source; public double Gain; public double Offset; public string ParameterName; public int ParameterID; public double[] arrayOfValue; public string[] arrayOfTimestamp; // public string[] arrayOfParameterName; public string[] arrayOfUnit; public string[] arrayOfDescription; public int[] arrayOfParameterID; public string[] arrayOfItemUrl; public string[] arrayOfSource; public string[] arrayOfModBusRegister; public string[] arrayOfGain; public string[] arrayOfOffset; } The Library contains methods like these: public CustomDataType GetDeviceParameters(string deviceName) { ...................... code getDeviceParametersObj.arrayOfParameterName; return getDeviceParametersObj; } public CustomDataType GetMaxMin(string parameterName, string period, string maxMin) { .....................................code getMaxMingObj.Value = (double)reader["MaxMinValue"]; getMaxMingObj.Timestamp = reader["MeasurementDateTime"].ToString(); getMaxMingObj.Unit = reader["Unit"].ToString(); getMaxMingObj.Description = reader["Description"].ToString(); return getMaxMingObj; } public CustomDataType GetSelectedMaxMinData(string[] parameterName, string period, string mode) {................................code selectedMaxMinObj.arrayOfValue = MaxMinvalueList.ToArray(); selectedMaxMinObj.arrayOfTimestamp = MaxMintimeStampList.ToArray(); selectedMaxMinObj.arrayOfDescription = MaxMindescriptionList.ToArray(); selectedMaxMinObj.arrayOfUnit = MaxMinunitList.ToArray(); return selectedMaxMinObj; } As illustrated thi different methods returns different data types,and it works fine for me but when i import the DLL and want to use the methods Visual studio shwos all the data types in the CustomDataType class as suggestion for all the methods even though the return different data.This is illusrtated in the picture below. As we can see from the picture with the suggestion of all the different return data the user can get confused and choose wrong return data for some of the methods. So my question is how can i improve this. so Visual studio suggest just the belonging return data type for each method.

  • Unfortunately App stopped when destroying SupportMapFragment

    - by user1408341
    I have the following problem. I have three fragments which are hosted in a TabHost. When I'm working with the app everything works fine. Now I like to end the app when the user hits the back button. Instead of terminating without errors I get the message Unfortunately App stopped. Then I said to myself something is wrong with the onDestroy() method of the FragmentActivity or with the onDestroyView method() of the Fragment. The problem is I cannot debug the point where the app crash. I get only the error:Fatal signal 11 (SIGSEGV). I then removed one by one each Fragment to identify which fragment causes the error. I could identify the fragment that I named BasicMapFragment. Something is wrong there. The code: public class BasicMapFragment extends SupportMapFragment implements LocationListener { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = super.onCreateView(inflater, container, savedInstanceState); //removeAllMarkers(); //setupGps(); //setupMap(); //setupMarkersFromModel(); //registerListeners(); return view; } } I commented out all my self written code to isolate the place where the error occurs. @Override public void onDestroy() { Log.d("ch.xxx.fragment.BasiceMapFragment", "On destroy called"); super.onDestroy(); } public void onDestroyView() { Log.d("ch.xxx.fragment.BasiceMapFragment", "On destroy view called"); super.onDestroyView(); } When I press the back button now the onDestroy() method of my FragmentActivity is first called like expected. Then the onDestroyView method is called on my BasicMapFragment class. At the end the onDestroy method is called - and then the application crash. Here is my layout file: <?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent"> <fragment android:id="@+id/map" android:layout_width="match_parent" android:layout_height="match_parent" class="com.google.android.gms.maps.SupportMapFragment"/> </FrameLayout> Resume: - Map is showed - I can work with the app. - When I leave out the BasicMapFragment the app finish without error. - When I add the BasicMapFragment the app returns an error when I press the back button Is there something that I have forgot to implement? Have somebody had the same trouble?

  • Spring OpenSessionInViewFilter with @Transactional annotation

    - by Gautam
    This is regarding Spring OpenSessionInViewFilter using with @Transactional annotation at service layer. i went through so many stack overflow post on this but still confused about whether i should use OpenSessionInViewFilter or not to avoid LazyInitializationException It would be great help if somebody help me find out answer to below queries. Is it bad practice to use OpenSessionInViewFilter in application having complex schema. using this filter can cause N+1 problem if we are using OpenSessionInViewFilter does it mean @Transactional not required? Below is my Spring config file <context:component-scan base-package="com.test"/> <context:annotation-config/> <bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource"> <property name="basename" value="resources/messages" /> <property name="defaultEncoding" value="UTF-8" /> </bean> <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" p:location="/WEB-INF/jdbc.properties" /> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close" p:driverClassName="${jdbc.driverClassName}" p:url="${jdbc.databaseurl}" p:username="${jdbc.username}" p:password="${jdbc.password}" /> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="configLocation"> <value>classpath:hibernate.cfg.xml</value> </property> <property name="configurationClass"> <value>org.hibernate.cfg.AnnotationConfiguration</value> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">${jdbc.dialect}</prop> <prop key="hibernate.show_sql">true</prop> <!-- <prop key="hibernate.hbm2ddl.auto">create</prop> --> </props> </property> </bean> <tx:annotation-driven /> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean>

  • Error reading values from dynamically created table rows in Android

    - by jaymo
    So I have a couple of dynamically created tablerows.Each TableRow has a couple of Textviews.I have a button that on clicked should get all the values of the second and third textviews in each Tablerow in the Table.

  • C++ - Error: expected unqualified-id before ‘using’

    - by Francisco P.
    Hello, everyone. I am having some trouble on a project I'm working on. Here's the header file for the calor class: #ifndef _CALOR_ #define _CALOR_ #include "gradiente.h" using namespace std; class Calor : public Gradiente { public: Calor(); Calor(int a); ~Calor(); int getTemp(); int getMinTemp(); void setTemp(int a); void setMinTemp(int a); void mostraSensor(); }; #endif When I try to compile it: calor.h|6|error: expected unqualified-id before ‘using’| Why does this happen? I've been searching online and learned this error occurs mostly due to corrupted included files. Makes no sense to me, though. This class inherits from gradiente: #ifndef _GRADIENTE_ #define _GRADIENTE_ #include "sensor.h" using namespace std; class Gradiente : public Sensor { protected: int vActual, vMin; public: Gradiente(); ~Gradiente(); } #endif Which in turn inherits from sensor #ifndef _SENSOR_ #define _SENSOR_ #include <iostream> #include <fstream> #include <string> #include "definicoes.h" using namespace std; class Sensor { protected: int tipo; int IDsensor; bool estadoAlerta; bool estadoActivo; static int numSensores; public: Sensor(/*PARAMETROS*/); Sensor(ifstream &); ~Sensor(); int getIDsensor(); bool getEstadoAlerta(); bool getEstadoActivo(); void setEstadoAlerta(int a); void setEstadoActivo(int a); virtual void guardaSensor(ofstream &); virtual void mostraSensor(); // FUNÇÃO COMUM /* virtual int funcaoComum() = 0; virtual int funcaoComum(){return 0;};*/ }; #endif For completeness' sake, here's definicoes.h #ifndef _DEFINICOES_ #define _DEFINICOES_ const unsigned int SENSOR_MOVIMENTO = 0; const unsigned int SENSOR_SOM = 1; const unsigned int SENSOR_PRESSAO = 2; const unsigned int SENSOR_CALOR = 3; const unsigned int SENSOR_CONTACTO = 4; const unsigned int MIN_MOVIMENTO = 10; const unsigned int MIN_SOM = 10; const unsigned int MIN_PRESSAO = 10; const unsigned int MIN_CALOR = 35; #endif Any help'd be much appreciated.

  • Issue with TagBuilder.MergeAttribute for parameter null

    - by The Yur
    I would like to use Razor's feature not to produce attribute output inside a tag in case when attribute's value is null. So when Razor meets <div class="@var" where @var is null, the output will be mere <div. I've created some Html extension method to write text inside tag. The method takes header text, level (h1..h6), and html attributes as simple object. The code is: public static MvcHtmlString WriteHeader(this HtmlHelper html, string s, int? hLevel = 1, object htmlAttributes = null) { if ((hLevel == null) || (hLevel < 1 || hLevel > 4) || (s.IsNullOrWhiteSpace())) return new MvcHtmlString(""); string cssClass = null, cssId = null, cssStyle = null; if (htmlAttributes != null) { var T = htmlAttributes.GetType(); var propInfo = T.GetProperty("class"); var o = propInfo.GetValue(htmlAttributes); cssClass = o.ToString().IsNullOrWhiteSpace() ? null : o.ToString(); propInfo = T.GetProperty("id"); o = propInfo.GetValue(htmlAttributes); cssId = o.ToString().IsNullOrWhiteSpace() ? null : o.ToString(); propInfo = T.GetProperty("style"); o = propInfo.GetValue(htmlAttributes); cssStyle = o.ToString().IsNullOrWhiteSpace() ? null : o.ToString(); } var hTag = new TagBuilder("h" + hLevel); hTag.MergeAttribute("id", cssId); hTag.MergeAttribute("class", cssClass); hTag.MergeAttribute("style", cssStyle); hTag.InnerHtml = s; return new MvcHtmlString(hTag.ToString()); } I found that in spite of null values for "class" and "style" attributes TagBuilder still puts them as empty strings, like <h1 class="" style="" But for id attribute it surprisingly works, so when id's value is null, there is no id attribute in tag. My question - is such behavior something that should actually happen? How can I achieve absent attributes with null values using TagBuilder? I tried this in VS2013, MVC 5.

  • Unable to use getInt() but able to use getString() for a sqlite database

    - by mwrazam
    I am using a cursor to access a sqlite database I have in my app. I am having trouble using the .getInt() on my database. My database is pre-created, and I have a few cursors that perform queries to interface with the information. Several of the columns in one of the tables are set as INTEGER type. I realize that sqlite has no built in check to make sure columns are indeed INT. However, when retrieving the data, I can use the .getString() function without any issues, but calling .getInt() causes the app to crash. Below is the relevant code. If I am missing anything, please let me know, and I'll add it in. Any help is greatly appreciated. Thank you very much. Cursor: public Cursor getSkitStats(int module, int skit) { Cursor mCursor = myDataBase.rawQuery("SELECT * FROM score WHERE mod="+module+" AND skit="+skit+"", null); if (mCursor != null) { mCursor.moveToFirst(); } return mCursor; } and I am using a simple Toast call to output the result of the query: Toast.makeText(getApplicationContext(), scoreContent.getInt(0), Toast.LENGTH_SHORT).show(); The variable scoreContent is the cursor. And here is the crash output: 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1659) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1675) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.access$1500(ActivityThread.java:121) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:943) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.os.Handler.dispatchMessage(Handler.java:99) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.os.Looper.loop(Looper.java:130) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.main(ActivityThread.java:3701) 07-08 23:53:31.726: E/AndroidRuntime(15685): at java.lang.reflect.Method.invokeNative(Native Method) 07-08 23:53:31.726: E/AndroidRuntime(15685): at java.lang.reflect.Method.invoke(Method.java:507) 07-08 23:53:31.726: E/AndroidRuntime(15685): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:866) 07-08 23:53:31.726: E/AndroidRuntime(15685): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:624) 07-08 23:53:31.726: E/AndroidRuntime(15685): at dalvik.system.NativeStart.main(Native Method) 07-08 23:53:31.726: E/AndroidRuntime(15685): Caused by: android.content.res.Resources$NotFoundException: String resource ID #0x2 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.content.res.Resources.getText(Resources.java:205) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.widget.Toast.makeText(Toast.java:258) 07-08 23:53:31.726: E/AndroidRuntime(15685): at jp.atomicideas.ne.Summary.onCreate(Summary.java:90) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1623) 07-08 23:53:31.726: E/AndroidRuntime(15685): ... 11 more

  • Calling a webservice synchronously from a Silverlight 3 application?

    - by Lasse V. Karlsen
    I am trying to reuse some .NET code that performs some calls to a data-access-layer type service. I have managed to package up both the input to the method and the output from the method, but unfortunately the service is called from inside code that I really don't want to rewrite in order to be asynchronous. Unfortunately, the webservice code generated in Silverlight only produces asynchronous methods, so I was wondering if anyone had working code that managed to work around this? I tried the recipe found here: The Easy Way To Synchronously Call WCF Services In Silverlight, but unfortunately it times out and never completes the call. Or rather, what seems to happen is that the completed event handler is called, but only after the method returns. I am suspecting that the event handler is called from a dispatcher or similar, and since I'm blocking the main thread here, it never completes until the code is actually back into the GUI loop. Or something like that. Here's my own version that I wrote before I found the above recipe, but it suffers from the same problem: public static object ExecuteRequestOnServer(Type dalInterfaceType, string methodName, object[] arguments) { string securityToken = "DUMMYTOKEN"; string input = "DUMMYINPUT"; object result = null; Exception resultException = null; object evtLock = new object(); var evt = new System.Threading.ManualResetEvent(false); try { var client = new MinGatServices.DataAccessLayerServiceSoapClient(); client.ExecuteRequestCompleted += (s, e) => { resultException = e.Error; result = e.Result; lock (evtLock) { if (evt != null) evt.Set(); } }; client.ExecuteRequestAsync(securityToken, input); try { var didComplete = evt.WaitOne(10000); if (!didComplete) throw new TimeoutException("A data access layer web service request timed out (" + dalInterfaceType.Name + "." + methodName + ")"); } finally { client.CloseAsync(); } } finally { lock (evtLock) { evt.Close(); evt = null; } } if (resultException != null) throw resultException; else return result; } Basically, both recipes does this: Set up a ManualResetEvent Hook into the Completed event The event handler grabs the result from the service call, and signals the event The main thread now starts the web service call asynchronously It then waits for the event to become signalled However, the event handler is not called until the method above has returned, hence my code that checks for evt != null and such, to avoid TargetInvocationException from killing my program after the method has timed out. Does anyone know: ... if it is possible at all in Silverlight 3 ... what I have done wrong above?

  • How does the CLR (.NET) internally allocate and pass around custom value types (structs)?

    - by stakx
    Question: Do all CLR value types, including user-defined structs, live on the evaluation stack exclusively, meaning that they will never need to be reclaimed by the garbage-collector, or are there cases where they are garbage-collected? Background: I have previously asked a question on SO about the impact that a fluent interface has on the runtime performance of a .NET application. I was particuarly worried that creating a large number of very short-lived temporary objects would negatively affect runtime performance through more frequent garbage-collection. Now it has occured to me that if I declared those temporary objects' types as struct (ie. as user-defined value types) instead of class, the garbage collector might not be involved at all if it turns out that all value types live exclusively on the evaluation stack. What I've found out so far: I did a brief experiment to see what the differences are in the CIL generated for user-defined value types and reference types. This is my C# code: struct SomeValueType { public int X; } class SomeReferenceType { public int X; } . . static void TryValueType(SomeValueType vt) { ... } static void TryReferenceType(SomeReferenceType rt) { ... } . . var vt = new SomeValueType { X = 1 }; var rt = new SomeReferenceType { X = 2 }; TryValueType(vt); TryReferenceType(rt); And this is the CIL generated for the last four lines of code: .locals init ( [0] valuetype SomeValueType vt, [1] class SomeReferenceType rt, [2] valuetype SomeValueType <>g__initLocal0, // [3] class SomeReferenceType <>g__initLocal1, // why are these generated? [4] valuetype SomeValueType CS$0$0000 // ) L_0000: ldloca.s CS$0$0000 L_0002: initobj SomeValueType // no newobj required, instance already allocated L_0008: ldloc.s CS$0$0000 L_000a: stloc.2 L_000b: ldloca.s <>g__initLocal0 L_000d: ldc.i4.1 L_000e: stfld int32 SomeValueType::X L_0013: ldloc.2 L_0014: stloc.0 L_0015: newobj instance void SomeReferenceType::.ctor() L_001a: stloc.3 L_001b: ldloc.3 L_001c: ldc.i4.2 L_001d: stfld int32 SomeReferenceType::X L_0022: ldloc.3 L_0023: stloc.1 L_0024: ldloc.0 L_0025: call void Program::TryValueType(valuetype SomeValueType) L_002a: ldloc.1 L_002b: call void Program::TryReferenceType(class SomeReferenceType) What I cannot figure out from this code is this: Where are all those local variables mentioned in the .locals block allocated? How are they allocated? How are they freed? Why are so many anonymous local variables needed and copied to-and-fro only to initialize my two local variables rt and vt?

  • Friendly way to parse XDocument

    - by Oli
    I have a class that various different XML schemes are created from. I create the various dynamic XDocuments via one (Very long) statement using conditional operators for optional elements and attributes. I now need to convert the XDocuments back to the class but as they are coming from different schemes many elements and sub elements may be optional. The only way I know of doing this is to use a lot of if statements. This approach doesn't seem very LINQ and uses a great deal more code than when I create the XDocument so I wondered if there is a better way to do this? An example would be to get <?xml version="1.0"?> <root xmlns="somenamespace"> <object attribute1="This is Optional" attribute2="This is required"> <element1>Required</element1> <element1>Optional</element1> <List1> Optional List Of Elements </List1> <List2> Required List Of Elements </List2> </object> </root> Into public class Object() { public string Attribute1; public string Attribute2; public string Element1; public string Element2; public List<ListItem1> List1; public List<ListItem2> List2; } In a more LINQ friendly way than this: public bool ParseXDocument(string xml) { XNamespace xn = "somenamespace"; XDocument document = XDocument.Parse(xml); XElement elementRoot = description.Element(xn + "root"); if (elementRoot != null) { //Get Object Element XElement elementObject = elementRoot.Element(xn + "object"); if(elementObject != null) { if(elementObject.Attribute(xn + "attribute1") != null) { Attribute1 = elementObject.Attribute(xn + "attribute1"); } if(elementObject.Attribute(xn + "attribute2") != null) { Attribute2 = elementObject.Attribute(xn + "attribute2"); } else { //This is a required Attribute so return false return false; } //If, If/Elses get deeper and deeper for the next elements and lists etc.... } else { //Object is a required element so return false return false; } } else { //Root is a required element so return false return false; } return true; } Update: Just to clarify the ParseXDocument method is inside the "Object" class. Every time an xml document is received the Object class instance has some or all of it's values updated.
