  • How to bind an ADF Table on button click

    - by Juan Manuel Formoso
    Coming from ASP.NET I'm having a hard time with basic ADF concepts. I need to bind a table on a button click, and for some reason I don't understand (I'm leaning towards page life cycle, which I guess is different from ASP.NET) it's not working. This is my ADF code: <af:commandButton text="#{viewcontrollerBundle.CMD_SEARCH}" id="cmdSearch" action="#{backingBeanScope.indexBean.cmdSearch_click}" partialSubmit="true"/> <af:table var="row" rowBandingInterval="0" id="t1" value="#{backingBeanScope.indexBean.transactionList}" partialTriggers="::cmdSearch" binding="#{backingBeanScope.indexBean.table}"> <af:column sortable="false" headerText="idTransaction" id="c2"> <af:outputText value="#{row.idTransaction}" id="ot4"/> </af:column> <af:column sortable="false" headerText="referenceCode" id="c5"> <af:outputText value="#{row.referenceCode}" id="ot7"/> </af:column> </af:table> This is cmdSearch_click: public String cmdSearch_click() { List l = new ArrayList(); Transaction t = new Transaction(); t.setIdTransaction(BigDecimal.valueOf(1)); t.setReferenceCode("AAA"); l.add(t); t = new Transaction(); t.setIdTransaction(BigDecimal.valueOf(2)); t.setReferenceCode("BBB"); l.add(t); setTransactionList(l); // AdfFacesContext.getCurrentInstance().addPartialTarget(table); return null; } The commented line also doesn't work. If I populate the list on my Bean's constructor, the table renders ok. Any ideas?

  • Loading velocity template inside a jar file

    - by Rafael
    I have a project where I want to load a velocity template to complete it with parameters. The whole application is packaged as a jar file. What I initially thought of doing was this: VelocityEngine ve = new VelocityEngine(); URL url = this.getClass().getResource("/templates/"); File file = new File(url.getFile()); ve = new VelocityEngine(); ve.setProperty(RuntimeConstants.RESOURCE_LOADER, "file"); ve.setProperty(RuntimeConstants.FILE_RESOURCE_LOADER_PATH, file.getAbsolutePath()); ve.setProperty(RuntimeConstants.FILE_RESOURCE_LOADER_CACHE, "true"); ve.init(); VelocityContext context = new VelocityContext(); if (properties != null) { stringfyNulls(properties); for (Map.Entry<String, Object> property : properties.entrySet()) { context.put(property.getKey(), property.getValue()); } } final String templatePath = templateName + ".vm"; Template template = ve.getTemplate(templatePath, "UTF-8"); String outFileName = File.createTempFile("p2d_report", ".html").getAbsolutePath(); BufferedWriter writer = new BufferedWriter(new FileWriter(new File(outFileName))); template.merge(context, writer); writer.flush(); writer.close(); And this works fine when I run it in eclipse. However, once I package the program and try to run it using the command line I get an error because the file could not be found. I imagine the problem is in this line: ve.setProperty(RuntimeConstants.FILE_RESOURCE_LOADER_PATH, file.getAbsolutePath()); Because in a jar the absolute file does not exist, since it's inside a zip, but I couldn't yet find a better way to do it. Anyone has any ideas?

  • Dynamic Array traversal in PHP

    - by Kristoffer Bohmann
    I want to build a hierarchy from a one-dimensional array and can (almost) do so with a more or less hardcoded code. How can I make the code dynamic? Perhaps with while(isset($array[$key])) { ... }? Or, with an extra function? Like this: $out = my_extra_traverse_function($array,$key); function array_traverse($array,$key=NULL) { $out = (string) $key; $out = $array[$key] . "/" . $out; $key = $array[$key]; $out = $array[$key] ? $array[$key] . "/" . $out : ""; $key = $array[$key]; $out = $array[$key] ? $array[$key] . "/" . $out : ""; $key = $array[$key]; $out = $array[$key] ? $array[$key] . "/" . $out : ""; return $out; } $a = Array(102=>101, 103=>102, 105=>107, 109=>105, 111=>109, 104=>111); echo array_traverse($a,104); Output: 107/105/109/111/104

  • Using label tags in a validation summary error list?

    - by patridge
    I was thinking about making use of <label> tags in my validation error summary on a failed form submit and I can't figure out if it is going to get me in trouble down the line. Can anyone think of a good reason to avoid this approach? Usability, functionality, design, or other issues are all helpful. I really like the idea of clicking a line item in the error list and being jumped to the offending input element, especially in a mobile HTML scenario where vertical orientation is more common and scrolling is a pain. So far the only problem I can find is that labels don't navigate for radio buttons or checkboxes without individual IDs (Clicking a label for a single ID-tagged radio/checkbox element alters its selection). It doesn't make it any worse than no label, though. Here is a stripped down HTML test sample of this idea (CSS omitted for simplicity). <div class="validation-errors"> <p>There was a problem saving your form.</p> <ul> <li><label for="select1">Select 1 is invalid.</label></li> <li><label for="text1">Text 1 is invalid.</label></li> <li><label for="textarea1">TextArea 1 is invalid.</label></li> <li><label for="radio1">Radio 1 is invalid.</label></li> <li><label for="checkbox1">Checkbox 1 is invalid.</label></li> </ul> </div> <form action="/somewhere"> <fieldset><legend>Some Form</legend> <ol> <li><label for="select1">select1</label> <select id="select1" name="select1"> <option value="value1">Value 1</option> <option value="value2">Value 2</option> <option selected="selected" value="value3">Value 3</option> </select></li> <li><label for="text1">text1</label> <input id="text1" name="text1" type="text" value="sometext" /></li> <li><label for="textarea1">textarea1</label> <textarea id="textarea1" name="textarea1" rows="5" cols="25">sometext</textarea></li> <li><ul> <li><label><input type="radio" name="radio1" value="value1" />Value 1</label></li> <li><label><input type="radio" name="radio1" value="value2" checked="checked" />Value 2</label></li> <li><label><input type="radio" name="radio1" value="value3" />Value 3</label></li> </ul></li> <li><ul> <li><label><input type="checkbox" name="checkbox1" value="value1" checked="checked" />Value 1</label></li> <li><label><input type="checkbox" name="checkbox1" value="value2" />Value 2</label></li> <li><label><input type="checkbox" name="checkbox1" value="value3" checked="checked" />Value 3</label></li> </ul></li> <li><input type="submit" value="Save &amp; Continue" /></li> </ol> </fieldset> </form> The only thing I have added to make the click-capable behavior more obvious is to add a CSS rule for the labels. .validation-errors label { text-decoration: underline; cursor: pointer; }

  • java annotations - problem with calling a locator class from a Vaadin Project

    - by George
    Hello, I'm not sure how to explain this without writing several pages so I hope the actual code is more expressive. I've made a jar containing multiple annotation declaration similar to the following: @Target(ElementType.PACKAGE) @Retention(RetentionPolicy.RUNTIME) public @interface MarkedPackage { } then I have made a test jar containing several classes in several packages and marked just one package with the above annotation (with package-info.java) like below: @myPackage.MarkedPackage package package.test.jar; this jar had in its build path the jar containing the annotations. then I made a static class that has a method (LoadPlugins) that retrieves a list with all the jars of a directory. Then it searches through the jars for the 'package-info' class and checks if that classes package contains the MarkedPackage annotation. by calling this: if (checkPackageAnnotation(thisClass.getPackage())) where thisClass is the package-info class retrieved via a classloader. and: public static boolean checkPackageAnnotation(AnnotatedElement elem) { System.out.println(elem.getAnnotations().length); if (elem == null || !elem.isAnnotationPresent(MarkedPackage.class)) return false; return true; } the elem.getAnnotatios().length is there for debug purposes. And the problem appears when I call the method from the static class: if I call it from a main function: public class MyMain { public static void main(String[] args){ PluginUtils.LoadPlugins(); } } everything works perfectly it displays '1' from that System.out.println(elem.getAnnotations().length); But if I call it from a button from my Vaadin project: header.addComponent(new Button("CallThat", new Button.ClickListener() { public void buttonClick(ClickEvent event) { PluginUtils.LoadPlugins(); } })); It displays '0' from that System.out.println(elem.getAnnotations().length); Also I should mention that I created the main inside my Vaadin project so it would have the exact same build path and resources. Is there a problem with web applications and that "@Retention(RetentionPolicy.RUNTIME)" ? hope I was clear enough... Hope someone has a solution for me... If you need more information - let me know. Thank you.

  • java - powermock whenNew doesnt seem to work, calls the actual constructor

    - by user1331243
    I have two final classes that are used in my unit test. I am trying to use whenNew on the constructor of a final class, but I see that it calls the actual constructor. The code is @PrepareForTest({A.class, B.class, Provider.class}) @Test public void testGetStatus() throws Exception { B b = mock(B.class); when(b.getStatus()).thenReturn(1); whenNew(B.class).withArguments(anyString()).thenReturn(b); Provider p = new Provider(); int val = p.getStatus(); assertTrue((val == 1)); } public class Provider { public int getStatus() { B b = new B("test"); return b.getStatus(); } } public final class A { private void init() { // ...do soemthing } private static A a; private A() { } public static A getInstance() { if (a == null) { a = new A(); a.init(); } return a; } } public final class B { public B() { } public B(String s) { this(A.getInstance(), s); } public B(A a, String s) { } public int getStatus() { return 0; } } On debug, I find that its the actual class B instance created and not the mock instance that is returned for new usage and assertion fails. Any pointers on how to get this working. Thanks

  • Problem with relative file path

    - by Richard Knop
    So here is my program, which works ok: import java.io.FileReader; import java.io.BufferedReader; import java.io.IOException; import java.util.Scanner; import java.util.Locale; public class ScanSum { public static void main(String[] args) throws IOException { Scanner s = null; double sum = 0; try { s = new Scanner(new BufferedReader(new FileReader("D:/java-projects/HelloWorld/bin/usnumbers.txt"))); s.useLocale(Locale.US); while (s.hasNext()) { if (s.hasNextDouble()) { sum += s.nextDouble(); } else { s.next(); } } } finally { s.close(); } System.out.println(sum); } } As you can see, I am using absolute path to the file I am reading from: s = new Scanner(new BufferedReader(new FileReader("D:/java-projects/HelloWorld/bin/usnumbers.txt"))); The problem arises when I try to use the relative path: s = new Scanner(new BufferedReader(new FileReader("usnumbers.txt"))); I get an error: Exception in thread "main" java.lang.NullPointerException at ScanSum.main(ScanSum.java:24) The file usnumbers.txt is in the same directory as the ScanSum.class file: D:/java-projects/HelloWorld/bin/ScanSum.class D:/java-projects/HelloWorld/bin/usnumbers.txt How could I solve this?

  • Testing ASP.NET webservice using NUnit and transferring session state

    - by herbertyeung
    I have a NUnit test class that starts an ASP.NET web service (using Microsoft.VisualStudio.WebHost.Server) which runs on http://localhost:1070 The problem I am having is that I want to create a session state within the NUnit test that is accessible by the ASP.NET web service on localhost:1070. I have done the following, and the session state can be created successfully inside the NUnit Test, but is lost when the web service is invoked: //Create a new HttpContext for NUnit Testing based on: //http://blogs.imeta.co.uk/jallderidge/archive/2008/10/19/456.aspx HttpContext.Current = new HttpContext( new HttpRequest("", "http://localhost:1070/", ""), new HttpResponse( new System.IO.StringWriter())); //Create a new HttpContext.Current for NUnit Testing System.Web.SessionState.SessionStateUtility.AddHttpSessionStateToContext( HttpContext.Current, new HttpSessionStateContainer("", new SessionStateItemCollection(), new HttpStaticObjectsCollection(), 20000, true, HttpCookieMode.UseCookies, SessionStateMode.Off, false)); HttpContext.Current.Session["UserName"] = "testUserName"; testwebService.testMethod(); I want to be able to get the session state created in the NUnit test for Session["UserName"] in the ASP.NET web service: [WebMethod(EnableSession=true)] public int testMethod() { string user; if(Session["UserName"] != null) { user = (string)Session["UserName"]; //Do some processing of the user return 1; } else return 0; } The web.config file has the following configuration for the session state configuration and would like to remain using InProc than rather StateServer Or SQLServer: <sessionState mode="InProc" stateConnectionString="tcpip=127.0.0.1:42424" cookieless="false" timeout="20"/>

  • How to query MySQL for exact length and exact UTF-8 characters

    - by oskarae
    I have table with words dictionary in my language (latvian). CREATE TABLE words ( value varchar(255) COLLATE utf8_unicode_ci DEFAULT NULL ) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci; And let's say it has 3 words inside: INSERT INTO words (value) VALUES ('teja'); INSERT INTO words (value) VALUES ('vejš'); INSERT INTO words (value) VALUES ('feja'); What I want to do is I want to find all words that is exactly 4 characters long and where second character is 'e' and third character is 'j' For me it feels that correct query would be: SELECT * FROM words WHERE value LIKE '_ej_'; But problem with this query is that it returs not 2 entries ('teja','vejš') but all three. As I understand it is because internally MySQL converts strings to some ASCII representation? Then there is BINARY addition possible for LIKE SELECT * FROM words WHERE value LIKE BINARY '_ej_'; But this also does not return 2 entries ('teja','vejš') but only one ('teja'). I believe this has something to do with UTF-8 2 bytes for non ASCII chars? So question: What MySQL query would return my exact two words ('teja','vejš')? Thank you in advance

  • Accessing we.config from Sharepoint web part

    - by philj
    I have a VS 2008 web parts project - in this project is a web.config file: something like this: ……. In my web part I am trying to access values in the appSetting section: I've tried all of the code below and each returns null: string Owner = ConfigurationManager.AppSettings.Get("MFOwner"); string stuff1 = ConfigurationManager.AppSettings["MFOwner"]; string stuff3 = WebConfigurationManager.AppSettings["MFOwner"]; string stuff4 = WebConfigurationManager.AppSettings.Get("MFOwner"); string stuff2 = ConfigurationManager.AppSettings["MFowner".ToString()]; I've tried this code I found: NameValueCollection sAll; sAll = ConfigurationManager.AppSettings; string a; string b; foreach (string s in sAll.AllKeys) { a = s; b = sAll.Get(s); } and stepped through it in debug mode - that is getting things like : FeedCacheTime FeedPageURL FeedXsl1 ReportViewerMessages which is NOT coming from anything in my web.config file....maybe a config file in sharepoint itself? How do I access a web.config (or any other kind of config file!) local to my web part??? thanks, Phil J

  • Retrieving license type (linux/windows/windows+sqlserver) for an Amazon EC2 instance via the API?

    - by Geir
    I need to calculate the hourly running costs for my Amazon EC2 instances. This varies even between instances with same hardware configs (instance types) because I use different amazon images (AMIs): some plain windows server and some windows server with sql server (both of them have additional costs compared with plain linux instances) The EC2 Java API has a describeInstances() method which returns Instance objects with metadata such as instance id, instance type (m1.small/large...), state (running,stopped..) public ip, etc. This Instance object also has a .getLicense().getPool() which according to the Java API should return "The license pool from which this license was used (ex: 'windows')." I thought this is were it may also give 'windows+sqlserver' or something to that effect. The getLicense() method does however return null.. I've navigated around the EC2 web console, not being able to find this information, but I'm hoping that it is possible - otherwise it would mean that you cannot identify the true hourly cost of an particular instance unless you know which AMI was used to create it in the first place (plain windows server or windows server with sql server). Anyone? Thanks :) /Geir

  • Android - overlay small check icon over specific image in gridview or change border

    - by oscar
    I've just asked a question about an hour ago, while waiting for replies, I've thought maybe I can achieve what I want differently. I was thinking of changing the image but it would be better if I could perhaps overlay something over the top of complete levels in the gridview i.e a small tick icon At the moment, when a level has been completed I am storing that with sharedpreferences So I have a gridView layout to display images that represent levels. Let's just say for this example I have 20 levels. When one level is complete is it possible to overlay the tick icon or somehow highlight the level image. Maybe change the border of the image?? Here are the image arrays I use int[] imageIDs = { R.drawable.one, R.drawable.two, R.drawable.three, R.drawable.four, R.drawable.five, R.drawable.six etc....... and then I have my code to set the images in gridView. Obviously there is more code in between. public View getView(int position, View convertView, ViewGroup parent) { ImageView imageView; if (convertView == null) { imageView = new ImageView(context); imageView.setLayoutParams(new GridView.LayoutParams(140, 140)); imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); imageView.setPadding(5, 5, 5, 5); } else { imageView = (ImageView) convertView; } imageView.setImageResource(imageIDs[position]); return imageView; would it be possible to do any of the above, even the border method would be fine. Thanks for any help

  • C# 4.0 'dynamic' doesn't set ref/out arguments

    - by Buu Nguyen
    I'm experimenting with DynamicObject. One of the things I try to do is setting the values of ref/out arguments, as shown in the code below. However, I am not able to have the values of i and j in Main() set properly (even though they are set correctly in TryInvokeMember()). Does anyone know how to call a DynamicObject object with ref/out arguments and be able to retrieve the values set inside the method? class Program { static void Main(string[] args) { dynamic proxy = new Proxy(new Target()); int i = 10; int j = 20; proxy.Wrap(ref i, ref j); Console.WriteLine(i + ":" + j); // Print "10:20" while expect "20:10" } } class Proxy : DynamicObject { private readonly Target target; public Proxy(Target target) { this.target = target; } public override bool TryInvokeMember(InvokeMemberBinder binder, object[] args, out object result) { int i = (int) args[0]; int j = (int) args[1]; target.Swap(ref i, ref j); args[0] = i; args[1] = j; result = null; return true; } } class Target { public void Swap(ref int i, ref int j) { int tmp = i; i = j; j = tmp; } }

  • Flex ChangeWatcher bind to a negative condition

    - by bedwyr
    I have a bindable getter in a component which informs me when a [hidden] timer is running. I also have a context menu which, if this timer is running, should disable one of the menu items. Is it possible to create a ChangeWatcher which watches for the negative condition of a bindable property/getter and changes the enabled property of the menu item? Here are the basic methods I'm trying to bind together: Class A: [Bindable] public function get isPlaying():Boolean { return (_timer != null) ? _timer.running : false; } Class B: private var _playingWatcher:ChangeWatcher; public function createContextMenu():void { //...blah blah, creating context menu var newItem:ContextMenuItem = new ContextMenuItem(); _playingWatcher = BindingUtils.bindProperty(newItem, "enabled", _classA, "isPlaying"); } In the code above, I have the inverse case: when isPlaying() is true, the menu item is enabled; I want it to only be enabled when the condition is false. I could create a second getter (there are other bindings which rely on the current getter) to return the inverse condition, but that sounds ugly to me: [Bindable] public function get isNotPlaying():Boolean { return !isPlaying; } Is this possible, or is there another approach I'm completely missing?

  • spring.net proxy factory with target type needs property virtual ?

    - by Vince
    Hi all, I'm creating spring.net proxy in code by using ProxyFactory object with ProxyTargetType to true to have a proxy on a non interfaced complex object. Proxying seems ok till i call a method on that object. The method references a public property and if this property is not virtual it's value is null. This doesn't happen if i use Spring.Aop.Framework.AutoProxy.InheritanceBasedAopConfigurer in spring config file but in this case i can't use this because spring context doesn't own this object. Is this normal to have such behavior or is there a tweak to perform what i want (proxying object virtual method without having to change properties virtual)? Note that i tried factory.AutoDetectInterfaces and factory.ProxyTargetAttributes values but doesn't help. My proxy creation code: public static T CreateMethodCallStatProxy<T>() { // Proxy factory ProxyFactory factory = new ProxyFactory(); factory.AddAdvice(new CallMonitorTrackerAdvice()); factory.ProxyTargetType = true; // Create instance factory.Target = Activator.CreateInstance<T>(); // Get proxy T proxiedClass = (T)factory.GetProxy(); return proxiedClass; } Thanks for your help

  • Deleting a node from linked list in C

    - by LuckySlevin
    My problem is deleting a node from linked list. I have two structs : typedef struct inner_list { int count; char word[100]; inner_list*next; } inner_list; typedef struct outer_list { char word [100]; inner_list * head; int count; outer_list * next; } outer_list; My problem is in deleting a node from outer_list linked list. For example when user entered aaa to delete, delete function should find the node with outer_list->word = aaa and delete this node and reconnect the list again. I tried the below code to do this. but After finding and deleting I'm losing the list. I don't know what's wrong. Please notice that outer_list have also a linked list of inner_list inside. void delnode(outer_list *head,char num[100]) { outer_list *temp, *m; temp=head; while(temp!=NULL) { if(strcmp(temp->word==num)==0) { if(temp==head) { head=temp->next; free(temp); return; } else { m->next=temp->next; free(temp); return; } }else { m=temp; temp= temp->next; } } printf(" ELEMENT %s NOT FOUND ", num); } What are your ideas about this?

  • Timer Service in ejb 3.1 - schedule calling timeout problem

    - by Greg
    Hi Guys, I have created simple example with @Singleton, @Schedule and @Timeout annotations to try if they would solve my problem. The scenario is this: EJB calls 'check' function every 5 secconds, and if certain conditions are met it will create single action timer that would invoke some long running process in asynchronous fashion. (it's sort of queue implementation type of thing). It then continues to check, but as long as long running process is there it won't start another one. Below is the code I came up with, but this solution does not work, because it looks like asynchronous call I'm making is in fact blocking my @Schedule method. @Singleton @Startup public class GenerationQueue { private Logger logger = Logger.getLogger(GenerationQueue.class.getName()); private List<String> queue = new ArrayList<String>(); private boolean available = true; @Resource TimerService timerService; @Schedule(persistent=true, minute="*", second="*/5", hour="*") public void checkQueueState() { logger.log(Level.INFO,"Queue state check: "+available+" size: "+queue.size()+", "+new Date()); if (available) { timerService.createSingleActionTimer(new Date(), new TimerConfig(null, false)); } } @Timeout private void generateReport(Timer timer) { logger.info("!!--timeout invoked here "+new Date()); available = false; try { Thread.sleep(1000*60*2); // something that lasts for a bit } catch (Exception e) {} available = true; logger.info("New report generation complete"); } What am I missing here or should I try different aproach? Any ideas most welcome :) Testing with Glassfish 3.0.1 latest build - forgot to mention

  • 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.

  • The OpenID Provider issued an assertion for an Identifier whose discovery information did not match

    I used sample code from DotNetOpenAuth.net to become my own OpenID Provider (OpenIDProviderWebForm) everything worked fine and I was able to test my OP against NerdDinner. now I want to customize the identifier like --- http://www.mydomain.com/user.aspx/Hash(Username+PrivateKey)~Username. everything works on OP side but on the NerdDinner application when the app tries to do HttpRequestInfo clientResponseInfo = new HttpRequestInfo("GET", auth, auth.PathAndQuery, headers, null); response = RelyingParty.GetResponse(clientResponseInfo); (you find these two lines of codes in AuthController.cs from NerdDinner) the response contains below error: The OpenID Provider issued an assertion for an Identifier whose discovery information did not match.

  • core data saving in textboxes in table view controller

    - by user1489709
    I have created a five column (text boxes) cell (row) in table view controller with an option of add button. When a user clicks on add button, a new row (cell) with five column (text boxe) is added in a table view controller with null values. I want that when user fills the text boxes the data should get saved in database or if he changes any data in previous text boxes also it get saved. this is my save btn coding.. -(void)textFieldDidEndEditing:(UITextField *)textField { row1=textField.tag; NSLog(@"Row is %d",row1); path = [NSIndexPath indexPathForRow:row1 inSection:0]; Input_Details *inputDetailsObject1=[self.fetchedResultsController objectAtIndexPath:path]; /* Update the Input Values from the values in the text fields. */ EditingTableViewCell *cell; cell = (EditingTableViewCell *)[self.tableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:row1 inSection:0]]; inputDetailsObject1.mh_Up= cell.cell_MH_up.text; inputDetailsObject1.mh_down=cell.cell_MH_dn.text; inputDetailsObject1.sewer_No=[NSNumber numberWithInt:[cell.cell_Sewer_No.text intValue]]; inputDetailsObject1.mhup_gl=[NSNumber numberWithFloat:[cell.cell_gl_MHUP.text floatValue]]; inputDetailsObject1.mhdn_gl=[NSNumber numberWithFloat:[cell.cell_gl_MHDN.text floatValue]]; inputDetailsObject1.pop_Ln=[NSNumber numberWithInt:[cell.cell_Line_pop.text intValue]]; inputDetailsObject1.sew_len=[NSNumber numberWithFloat:[cell.cell_Sewer_len.text floatValue]]; [self saveContext]; NSLog(@"Saving the MH_up value %@ is saved in save at index path %d",inputDetailsObject1.mh_Up,row1); [self.tableView reloadData]; }

  • Php index page utitlizing an idea for a superswitch...

    - by Matt
    I dont know if this is a great idea...or a crap one. But I was thinking I may use one page to display all my pages using includes. Here is what my index.php would look like...on the functions include there is a function called "superSwitch" which will determine what requested page will be included....for instance if I do a get ?a=a it will goto the function superSwitch(a) superSwitch will take it and associate it with (login.php) then respond with such... here is the code for the index.php...please let me know if this makes sense and might work, or should I just stick to long blocks of code (which is why I am trying this because I hate long pages full of code...) of course as you can tell it is not actually including anything yet...the print is for debugging purposes. :) Thanks, Matt <?php //includes Functions include_once('inc/func.inc.php'); //set superget variable $superget = @$_GET['a']; //check if superget is set or null if (!$superget) { echo "Nothing Requested :)"; } else { //sanitizes the superget request $supergetr = supergetSanitize($superget) //uses the result "good" or "nogood" to determine what happens if ( $supergetr == "good" ) { //pulls superSwitch value of the request $ssresult = superSwitch($superget); print_r ($ssresult); } //if the sanitize is nogood else { //the superSwitch is instructed to respond with a 404 page $superget = "404" $ssresult = superSwitch($superget); print_r ($ssresult); } } ?>

  • Java swing app can't find image

    - by KáGé
    Hello, I'm making a torpedo game for school in java with swing gui, please see the zipped source HERE. I use custom button icons and mouse cursors of images stored in the /bin/resource/graphics/default folder's subfolders, where the root folder is the program's root folder (it will be the root in the final .jar as well I suppose) which apart from "bin" contains a "main" folder with all the classes. The relative path of the resources is stored in MapStruct.java's shipPath and mapPath variables. Now Battlefield.java's PutPanel class finds them all right and sets up its buttons' icons fine, but every other class fail to get their icons, e.g. Table.java's setCursor, which should set the mouse cursor for all its elements for the selected ship's image or Field.java's this.button.setIcon(icon); in the constructor, which should set the icon for the buttons of the "water". I watched with debug what happens, and the images stay null after loading, though the paths seem to be correct. I've also tried to write a test file in the image folder but the method returns a filenotfound exception. I've tried to get the path of the class to see if it runs from the supposed place and it seems it does, so I really can't find the problem now. Could anyone please help me? Thank you.

  • Programming style question on how to code functions

    - by shawnjan
    Hey all! So, I was just coding a bit today, and I realized that I don't have much consistency when it comes to a coding style when programming functions. One of my main concerns is whether or not its proper to code it so that you check that the input of the user is valid OUTSIDE of the function, or just throw the values passed by the user into the function and check if the values are valid in there. Let me sketch an example: I have a function that lists hosts based on an environment, and I want to be able to split the environment into chunks of hosts. So an example of the usage is this: listhosts -e testenv -s 2 1 This will get all the hosts from the "testenv", split it up into two parts, and it is displaying part one. In my code, I have a function that you pass it in a list, and it returns a list of lists based on you parameters for splitting. BUT, before I pass it a list, I first verify the parameters in my MAIN during the getops process, so in the main I check to make sure there are no negatives passed by the user, I make sure the user didnt request to split into say, 4 parts, but asking to display part 5 (which would not be valid), etc. tl;dr: Would you check the validity of a users input the flow of you're MAIN class, or would you do a check in your function itself, and either return a valid response in the case of valid input, or return NULL in the case of invalid input? Obviously both methods work, I'm just interested to hear from experts as to which approach is better :) Thanks for any comments and suggestions you guys have!
