• jquery ajax, array and json

  - by sea_1987

  I am trying to log some input values into an array via jquery and then use those to run a method server side and get the data returned as JSON. The HTML looks like this, <div class="segment"> <div class="label"> <label>Choose region: </label> </div> <div class="column w190"> <div class="segment"> <div class="input"> <input type="checkbox" class="radio" value="Y" name="area[Nationwide]" id="inp_Nationwide"> </div> <div class="label "> <label for="inp_Nationwide">Nationwide</label> </div> <div class="s">&nbsp;</div> </div> </div> <div class="column w190"> <div class="segment"> <div class="input"> <input type="checkbox" class="radio" value="Y" name="area[Lancashire]" id="inp_Lancashire"> </div> <div class="label "> <label for="inp_Lancashire">Lancashire</label> </div> <div class="s">&nbsp;</div> </div> </div> <div class="column w190"> <div class="segment"> <div class="input"> <input type="checkbox" class="radio" value="Y" name="area[West_Yorkshire]" id="inp_West_Yorkshire"> </div> <div class="label "> <label for="inp_West_Yorkshire">West Yorkshire</label> </div> <div class="s">&nbsp;</div> </div> <div class="s">&nbsp;</div> </div> I have this javascript the detect whether the items are checked are not if($('input.radio:checked')){ } What I dont know is how to get the values of the input into an array so I can then send the information through AJAX to my controller. Can anyone help me?

• Java JMS Messaging

  - by London

  Hello, I have a working example of sending message to server and server receiving it via qpid messaging. Here is simple hello world to send to server : http://pastebin.com/M7mSECJn And here is server which receives requests and sends response(the current client doesn't receive response) : http://pastebin.com/2mEeuzrV Here is my property file : http://pastebin.com/TLEFdpXG They all work perfectly, I can see the messages in the qpid queue via Qpid JMX management console. These examples are downloaded from https://svn.apache.org/repos/asf/qpid/trunk/qpid/java/client/example (someone may need it also). I've done Jboss messaging using spring before, but I can't manage to do the same with qpid. With jboss inside applicationsContext I had beans jndiTemplate, conectionFactory, destinationQueue, and jmscontainer like this : <!-- Queue configuration --> <bean id="jndiTemplate" class="org.springframework.jndi.JndiTemplate"> <property name="environment"> <props> <prop key="java.naming.factory.initial">org.jnp.interfaces.NamingContextFactory</prop> <prop key="java.naming.provider.url">jnp://localhost:1099</prop> <prop key="java.naming.factory.url.pkgs">org.jboss.naming:org.jnp.interfaces</prop> <prop key="java.naming.security.principal">admin</prop> <prop key="java.naming.security.credentials">admin</prop> </props> </property> </bean> <bean id="connectionFactory" class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiTemplate" ref="jndiTemplate" /> <property name="jndiName" value="ConnectionFactory" /> </bean> <bean id="queueDestination" class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiTemplate" ref="jndiTemplate" /> <property name="jndiName"> <value>queue/testQueue</value> </property> </bean> <bean id="jmsContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer"> <property name="connectionFactory" ref="connectionFactory" /> <property name="destination" ref="queueDestination" /> <property name="messageListener" ref="listener" /> </bean> and of course sender and listener : Now I'd like to rewrite this qpid example using spring context logic. Can anyone help me?

• Stringtemplate: is it ok to Apply Templates, in which HashMap uses, To Multi-Valued Attributes

  - by user1071830

  There is two template in my .stg file, and both of them apply on multi-value a HashMap. The HashMap is employed as an injected object. And I need those instance of HashMap can be injected for many times. My trouble is, when I switch to another template, ANTLR seems to consider the second HashMap as a List -- multipul objects and null value. Part of my .stg file shows as follows: tpl_hash(BAR, FOO) ::= << <FOO:foo(); separator="\n"> <BAR:bar(); separator="\n"> >> foo(nn) ::= << foo: <nn.name; null="NULL"> . <nn.national; null="NULL"> >> bar(mm) ::= << bar: <mm.name> @ <mm.national> >> Part of my .g file shows: HashMap hm = new HashMap(); hm.put("name", $name.text); hm.put("national", "German"); tpl_hash.add("FOO",new HashMap(hm)); HashMap hm2 = new HashMap(); hm2.put("name", $name.text); hm2.put("national", "German"); tpl_hash.add("BAR",new HashMap(hm2)); The result I expect is : bar: Kant @ German foo: Russell @ England But, I got: foo: NULL . NULL foo: NULL . NULL bar: @ bar: @ If we replace BAR with FOO, as is, keeping FOO and BAR with identical template, the output is right, like the following. bar: Russell @ German bar: Russell @ German In docs, "synchronized ST add (String name, Object value) in org.stringtemplate.v4.ST" said: "If you send in a List and then inject a single value element, add() copies original list and adds the new value." What about a HashMap? Does ANTLR consider the HashMap, key/value pair access, an object purposely, as a List and as multi-value injected by mistake? Thanks a lot in advance.

• Using native MySQL driver in Erlang

• Cascade Saves with Fluent NHibernate AutoMapping - Old Anwser Still Valid?

  - by Glenn

  I want to do exactly what this question asks: http://stackoverflow.com/questions/586888/cascade-saves-with-fluent-nhibernate-automapping Using Fluent Nhibernate Mappings to turn on "cascade" globally once for all classes and relation types using one call rather than setting it for each mapping individually. The answer to the earlier question looks great, but I'm afraid that the Fluent Nhibernate API altered its .WithConvention syntax last year and broke the answer... either that or I'm missing something. I keep getting a bunch of name space not found errors relating to the IOneToOnePart, IManyToOnePart and all their variations: "The type or namespace name 'IOneToOnePart' could not be found (are you missing a using directive or an assembly reference?)" I've tried the official example dll's, the RTM dll's and the latest build and none of them seem to make VS 2008 see the required namespace. The second problem is that I want to use the class with my AutoPersistenceModel but I'm not sure where to this line: .ConventionDiscovery.AddFromAssemblyOf() in my factory creation method. private static ISessionFactory CreateSessionFactory() { return Fluently.Configure() .Database(SQLiteConfiguration.Standard.UsingFile(DbFile)) .Mappings(m => m.AutoMappings .Add(AutoMap.AssemblyOf<Shelf>(type => type.Namespace.EndsWith("Entities")) .Override<Shelf>(map => { map.HasManyToMany(x => x.Products).Cascade.All(); }) ) )//emd mappings .ExposeConfiguration(BuildSchema) .BuildSessionFactory();//finalizes the whole thing to send back. } Below is the class and using statements I'm trying using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO; using FluentNHibernate.Conventions; using FluentNHibernate.Cfg; using FluentNHibernate.Cfg.Db; using NHibernate; using NHibernate.Cfg; using NHibernate.Tool.hbm2ddl; using FluentNHibernate.Mapping; namespace TestCode { public class CascadeAll : IHasOneConvention, IHasManyConvention, IReferenceConvention { public bool Accept(IOneToOnePart target) { return true; } public void Apply(IOneToOnePart target) { target.Cascade.All(); } public bool Accept(IOneToManyPart target) { return true; } public void Apply(IOneToManyPart target) { target.Cascade.All(); } public bool Accept(IManyToOnePart target) { return true; } public void Apply(IManyToOnePart target) { target.Cascade.All(); } } }

• Create a screen like the iPhone home screen with Scrollview and Buttons

  - by Anthony Chan

  Hi, I'm working on a project and need to create a screen similar to the iPhone home screen: A scrollview with multiple pages A bunch of icons When not in edit mode, swipe through different pages (even I started the touch on an icon) When not in edit mode, tap an icon to do something When in edit mode, drag the icon to swap places, and even swap to different pages When in edit mode, tap an icon to remove it Previously I read from several forums that I have to subclass UIScrollview in order to have touch input for the UIViews on top of it. So I subclassed it overriding the methods to handle touches: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { //If not dragging, send event to next responder if (!self.dragging) [self.nextResponder touchesBegan:touches withEvent:event]; else [super touchesBegan:touches withEvent:event]; } In general I've override the touchesBegan:, touchesMoved: and touchesEnded: methods similarly. Then in the view controller, I added to following code: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; UIView *hitView = (UIView *)touch.view; if ([hitView isKindOfClass:[UIView class]]) { [hitView doSomething]; NSLog(@"touchesBegan"); } } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { // Some codes to move the icons NSLog(@"touchesMoved"); } - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { NSLog(@"touchesEnded"); } When I run the app, I have the touchesBegan method detected correctly. However, when I tried to drag the icon, the icon just moved a tiny bit and then the page started to scroll. In console, it logged with 2 or 3 "touchesMoved" message only. However, I learned from another project that it should logged tonnes of "touchesMoved" message as long as I'm still dragging on the screen. (I'm suspecting I have the delaysContentTouches set to YES, so it delays a little bit when I tried to drag the icons. After that minor delay, it sends to signal back to the scrollview to scroll through the page. Please correct me if I'm wrong.) So if any help on the code to perform the above tasks would be greatly appreciated. I've stuck in this place for nearly a week with no hope. Thanks a lot.

• Where would I implement this array to pass?

  - by Keeano Martin

  I currently build an NSMutableArray in Class A.m within the ViewDidLoad Method. - (void)viewDidLoad { [super viewDidLoad]; //Question Array Setup and Alloc stratToolsDict = [[NSMutableDictionary alloc] initWithObjectsAndKeys:countButton,@"count",camerButton,@"camera",videoButton,@"video",textButton,@"text",probeButton,@"probe", nil]; stratTools = [[NSMutableArray alloc] initWithObjects:@"Tools",stratToolsDict, nil]; stratObjectsDict = [[NSMutableDictionary alloc]initWithObjectsAndKeys:stratTools,@"Strat1",stratTools,@"Strat2",stratTools,@"Strat3",stratTools,@"Strat4", nil]; stratObjects = [[NSMutableArray alloc]initWithObjects:@"Strategies:",stratObjectsDict,nil]; QuestionDict = [[NSMutableDictionary alloc]initWithObjectsAndKeys:stratObjects,@"Question 1?",stratObjects,@"Question 2?",stratObjects,@"Question 3?",stratObjects,@"Question 4?",stratObjects,@"Question 5?", nil]; //add strategys to questions QuestionsList = [[NSMutableArray alloc]init]; for (int i = 0; i < 1; i++) { [QuestionsList addObject:QuestionDict]; } NSLog(@"Object: %@",QuestionsList); At the end of this method you will see QuestionsList being initialized and now I need to send this Array to Class B. So I place its setters and getters using the @property and @Synthesize method. Class A.h @property (retain, nonatomic) NSMutableDictionary *stratToolsDict; @property (retain, nonatomic) NSMutableArray *stratTools; @property (retain, nonatomic) NSMutableArray *stratObjects; @property (retain, nonatomic) NSMutableDictionary *QuestionDict; @property (retain, nonatomic) NSMutableArray *QuestionsList; Class A.m @synthesize QuestionDict; @synthesize stratToolsDict; @synthesize stratObjects; @synthesize stratTools; @synthesize QuestionsList; I use the property method because I am going to call this variable from Class B and want to be able to assign it to another NSMutableArray. I then add the @property and @class for Class A to Class B.h as well as declare the NSMutableArray in the @interface. #import "Class A.h" @class Class A; @interface Class B : UITableViewController<UITableViewDataSource, UITableViewDelegate>{ NSMutableArray *QuestionList; Class A *arrayQuestions; } @property Class A *arrayQuestions; Then I call NSMutableArray from Class A in the Class B.m -(id)initWithStyle:(UITableViewStyle)style { if ([super initWithStyle:style] != nil) { //Make array arrayQuestions = [[Class A alloc]init]; QuestionList = arrayQuestions.QuestionsList; Right after this I Log the NSMutableArray to view values and check that they are there and it returns NIL. //Log test NSLog(@"QuestionList init method: %@",QuestionList); Info about Class B- Class B is a UIPopOverController for Class A, Class B has one View which holds a UITableView which I have to populate the results of Class A's NSMutableArray. Why is the NsMutableArray coming back as NIL? Ultimately would like some help figuring it out as well, it seems to really have me confused. Help is greatly appreciated!!

• Sharing a file from Android to Gmail or to Dropbox

  - by Calaf

  To share a simple text file, I started by copying verbatim from FileProvider's manual page: <application android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <provider android:name="android.support.v4.content.FileProvider" android:authorities="com.mycorp.helloworldtxtfileprovider.MainActivity" android:exported="false" android:grantUriPermissions="true" > <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/my_paths" /> </provider> <activity android:name="com.mycorp.helloworldtxtfileprovider.MainActivity" ... Then I saved a text file and used, again nearly verbatim, the code under Sending binary content. (Notice that this applies more accurately in this case than "Sending text content" since we are sending a file, which happens to be a text file, rather than just a string of text.) For the convenience of duplication on your side, and since the code is in any case so brief, I'm including it here in full. public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); String filename = "hellow.txt"; String fileContents = "Hello, World!\n"; byte[] bytes = fileContents.getBytes(); FileOutputStream fos = null; try { fos = this.openFileOutput(filename, MODE_PRIVATE); fos.write(bytes); } catch (IOException e) { e.printStackTrace(); } finally { try { fos.close(); } catch (IOException e) { e.printStackTrace(); } } File file = new File(filename); Intent shareIntent = new Intent(); shareIntent.setAction(Intent.ACTION_SEND); shareIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file)); shareIntent.setType("application/txt"); startActivity(Intent.createChooser(shareIntent, getResources().getText(R.string.send_to))); file.delete(); } } Aside from adding a value for send_to in res/values/strings.xml, the only other change I did to the generic Hello, World that Eclipse creates is to add the following in res/xml/my_paths.xml (as described on the page previously referenced. <paths xmlns:android="http://schemas.android.com/apk/res/android"> <Files-path name="files" path="." /> </paths> This code runs fine. It shows a list of intent recipients. But sending the text file to either Dropbox or to Gmail fails. Dropbox sends the notification "Uploading to Dropbox" followed by "Upload failed: my_file.txt". After "sending message.." Gmail sends "Couldn't send attachment". What is wrong?

• problem with two .NET threads and hardware access

  - by mack369

  I'm creating an application which communicates with the device via FT2232H USB/RS232 converter. For communication I'm using FTD2XX_NET.dll library from FTDI website. I'm using two threads: first thread continuously reads data from the device the second thread is the main thread of the Windows Form Application I've got a problem when I'm trying to write any data to the device while the receiver's thread is running. The main thread simply hangs up on ftdiDevice.Write function. I tried to synchronize both threads so that only one thread can use Read/Write function at the same time, but it didn't help. Below code responsible for the communication. Note that following functions are methods of FtdiPort class. Receiver's thread private void receiverLoop() { if (this.DataReceivedHandler == null) { throw new BackendException("dataReceived delegate is not set"); } FTDI.FT_STATUS ftStatus = FTDI.FT_STATUS.FT_OK; byte[] readBytes = new byte[this.ReadBufferSize]; while (true) { lock (FtdiPort.threadLocker) { UInt32 numBytesRead = 0; ftStatus = ftdiDevice.Read(readBytes, this.ReadBufferSize, ref numBytesRead); if (ftStatus == FTDI.FT_STATUS.FT_OK) { this.DataReceivedHandler(readBytes, numBytesRead); } else { Trace.WriteLine(String.Format("Couldn't read data from ftdi: status {0}", ftStatus)); Thread.Sleep(10); } } Thread.Sleep(this.RXThreadDelay); } } Write function called from main thread public void Write(byte[] data, int length) { if (this.IsOpened) { uint i = 0; lock (FtdiPort.threadLocker) { this.ftdiDevice.Write(data, length, ref i); } Thread.Sleep(1); if (i != (int)length) { throw new BackendException("Couldnt send all data"); } } else { throw new BackendException("Port is closed"); } } Object used to synchronize two threads static Object threadLocker = new Object(); Method that starts the receiver's thread private void startReceiver() { if (this.DataReceivedHandler == null) { return; } if (this.IsOpened == false) { throw new BackendException("Trying to start listening for raw data while disconnected"); } this.receiverThread = new Thread(this.receiverLoop); //this.receiverThread.Name = "protocolListener"; this.receiverThread.IsBackground = true; this.receiverThread.Start(); } The ftdiDevice.Write function doesn't hang up if I comment following line: ftStatus = ftdiDevice.Read(readBytes, this.ReadBufferSize, ref numBytesRead);

• iPhone JSON Object

  - by Cosizzle

  Hello, I'm trying to create a application that will retrieve JSON data from an HTTP request, send it to a the application main controller as a JSON object then from there do further processing with it. Where I'm stick is actually creating a class that will serve as a JSON class in which will take a URL, grab the data, and return that object. Alone, im able to make this class work, however I can not get the class to store the object for my main controller to retrieve it. Because im fairly new to Objective-C itself, my thoughts are that im messing up within my init call: -initWithURL:(NSString *) value { responseData = [[NSMutableData data] retain]; NSString *theURL = value; NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:theURL]]; [[NSURLConnection alloc] initWithRequest:request delegate:self]; return self; } The processing of the JSON object takes place here: - (void)connectionDidFinishLoading:(NSURLConnection *)connection { [connection release]; NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]; [responseData release]; NSError *jsonError; SBJSON *json = [[SBJSON new] autorelease]; NSDictionary *parsedJSON = [json objectWithString:responseString error:&jsonError]; // NSArray object. listings = [parsedJSON objectForKey:@"posts"]; NSEnumerator *enumerator = [listings objectEnumerator]; NSDictionary* item; // to prove that it does work. while (item = (NSDictionary*)[enumerator nextObject]) { NSLog(@"posts:id = %@", [item objectForKey:@"id"]); NSLog(@"posts:address = %@", [item objectForKey:@"address"]); NSLog(@"posts:lat = %@", [item objectForKey:@"lat"]); NSLog(@"posts:lng = %@", [item objectForKey:@"lng"]); } [responseString release]; } Now when calling the object within the main controller I have this bit of code in the viewDidLoad method call: - (void)viewDidLoad { [super viewDidLoad]; JSON_model *jsonObj = [[JSON_model alloc] initWithURL:@"http://localhost/json/faith_json.php?user=1&format=json"]; NSEnumerator *enumerator = [[jsonObj listings] objectEnumerator]; NSDictionary* item; // while (item = (NSDictionary*)[enumerator nextObject]) { NSLog(@"posts:id = %@", [item objectForKey:@"id"]); NSLog(@"posts:address = %@", [item objectForKey:@"address"]); NSLog(@"posts:lat = %@", [item objectForKey:@"lat"]); NSLog(@"posts:lng = %@", [item objectForKey:@"lng"]); } }

• When does the .NET FormAuthentication ticket get checked and how do I tap into this event?

  - by Mustafakidd

  Hello everyone - We are attempting to integrate an ASP.NET MVC site with our client's SSO system using PingFederate. I would like to use the built in FormsAuthentication framework to do this. The way I've gone about it so far is: Set up my Web.config so that my FormsAuthentication LoginURL goes to my site's "BeginAuthentication" action on a "Security" controller. From this action, I set up some session variables (what URL was being accessed, for example, since Ping won't send this info back to me), and then redirect to our client's login page on an external site (www.client.com/Login for example). From here, the authentication takes place and a cookie is generated on the same domain as the one that our application is running on which contains the unique identifier of the authenticated user, I've set it up so that once this happens, the Ping server will redirect to my "EndAuthentication" action on my "Security" controller. In this action, I call my membership class's "ValidateUser" method which takes this unique identifier from the cookie and loads in the user on our application that this ID refers to. I save that logged in user in our Session (Session["LoggedInAs"], for example) and expire the cookie that contains the id of the authenticated user that the SSO system provided for me. All of this works well. The issue I'm wondering about is what happens after our user has already authenticated and manually goes back to our client's login page (www.client.com/login) and logs in as another user. If they do that, then the flow from #2 above to number 3 happens as normal - but since there already exists an authenticated user on our site, it seems as though the FormsAuthentication system doesn't bother kicking off anything so I don't get a chance to check for the cookie I'm looking for to login as this new user. What I'd like to do is, somewhere in my Global.asax file (probably FormsAuthenticate_OnAuthenticate), check to see if the cookie that the SSO system sends to me exists, and if so, sign out of the application using FormsAuthentication.SignOut(). Another issue that seems to be related is that if I let my Session expire, the FormsAuthentication still seems to think I am authenticated and it lets me access a page even though no currently logged in user exists in my Session, so the page doesn't render correctly. Should I tap into the Session_End event and do FormsAuthentication.SignOut() here as well? Basically, I want to know when the authentication ticket created by System.Web.Security.FormsAuthentication.SetAuthCookie(..) gets checked in the flow of a request so that I can determine whether I need to SignOut() and force revalidation or not. Thanks for any help. Sorry for the length of this message, trying to be as detailed as possible. Mustafa

• Problem with JSON, Struts 2 and Ajax.

  - by Javi

  Hello, I have an apllication with Struts 2, Spring and I want to send JSON as a response to an Ajax request, but my server in not sending the JSON in the response. I have this base package: <package name="myApp-default" extends="struts-default"> <result-types> <result-type name="tiles" class="org.apache.struts2.views.tiles.TilesResult" /> <result-type name="json" class="com.googlecode.jsonplugin.JSONResult"> <param name="enableGZIP">true</param> <param name="noCache">true</param> <param name="defaultEncoding">ISO-8859-1</param> </result-type> </result-types> </package> And another package which extends the previous one. <package namespace="/rest" name="rest" extends="myApp-default"> <action name="login" class="restAction" method="login"> <result type="json"/> </action> So I call with jQuery Ajax and debugging it I see it enters in the Action restAction in the method login and it also enters in the method getJsonData() because I have set two breakpoints and the program is stopped first in login and then in getJsonData. public class RestAction extends BaseAction { private String login; private String password; private String jsonData; public String login() { jsonData = "changed"; return Action.SUCCESS; } //I ommit getter/setters for login and password @JSON(name="jsonData") public String getJsonData() { return jsonData; } public void setJsonData(String jsonData) { this.jsonData = jsonData; } } My ajax looks like this: $.ajax({type: 'GET', url: this_url, data: pars, cache:false, success: handleResponse, error: handleError}); With firebug I see that the response to my request is completely void (though I have seen that the data saved in pars variable has been populated to the action and the methods have been executed correctly). And maybe for that reason my ajax enters in my handleError function where xmlHttpRequest.readyState is 4 and xmlHttpRequest.status is 0. Can anyone tell me what may the problem be? Thanks.

• performance problem looping through table rows

  - by Sridhar

  Hi, I am using jquery to loop through table rows and save the data. If the table has 200 rows it is performing slow. I am getting the javascript message "Stop Running this script" in IE when I call this method. Following is the code I am using to loop through table rows. Can you please let me know if there is a better way to do this. function SaveData() { var $table = $('#' + gridid); var rows = $table.find('tbody > tr').get(); var transactions = []; var $row, empno, newTransaction, $rowChildren; $.each(rows, function(index, row) { $row = $(row); $rowChildren = $row.children("td"); if ($rowChildren.find("input[id*=hRV]").val() === '1') { empno = $rowChildren.find("input[id*=tEmpno]").val(); newTransaction = new Array(); newTransaction[0] = company; newTransaction[1] = $rowChildren.find("input[id*=tEmpno]").val(); newTransaction[2] = $rowChildren.find("input[id*=tPC]").val(); newTransaction[3] = $rowChildren.find("input[id*=hQty]").val(); newTransaction[4] = $rowChildren.find("input[id*=hPR]").val(); newTransaction[5] = $rowChildren.find("input[id*=tJC]").val(); newTransaction[6] = $rowChildren.find("input[id*=tL1]").val(); newTransaction[7] = $rowChildren.find("input[id*=tL2]").val(); newTransaction[8] = $rowChildren.find("input[id*=tL3]").val(); newTransaction[9] = $rowChildren.find("input[id*=tL4]").val(); newTransaction[10] = $rowChildren.find("input[id*=tL5]").val(); newTransaction[11] = $rowChildren.find("input[id*=tL6]").val(); newTransaction[12] = $rowChildren.find("input[id*=tL7]").val(); newTransaction[13] = $rowChildren.find("input[id*=tL8]").val(); newTransaction[14] = $rowChildren.find("input[id*=tL9]").val(); newTransaction[15] = $rowChildren.find("input[id*=tL10]").val(); newTransaction[16] = $rowChildren.find("input[id*=tSF]").val(); newTransaction[17] = $rowChildren.find("input[id*=tCG]").val(); newTransaction[18] = $rowChildren.find("input[id*=tTF]").val(); newTransaction[19] = $rowChildren.find("input[id*=tWK]").val(); newTransaction[20] = $rowChildren.find("input[id*=tAI]").val(); newTransaction[21] = $rowChildren.find("input[id*=tWC]").val(); newTransaction[22] = $rowChildren.find("input[id*=tPI]").val(); newTransaction[23] = "E"; var record = newTransaction.join(';'); transactions.push(record); } }); if (transactions.length > 0) { var strTransactions = transactions.join('|'); //send data to server //here ajax function is called to save data. } }

• How to create a Uri instance parsed with GenericUriParserOptions.DontCompressPath

  - by Andrew Arnott

  When the .NET System.Uri class parses strings it performs some normalization on the input, such as lower-casing the scheme and hostname. It also trims trailing periods from each path segment. This latter feature is fatal to OpenID applications because some OpenIDs (like those issued from Yahoo) include base64 encoded path segments which may end with a period. How can I disable this period-trimming behavior of the Uri class? Registering my own scheme using UriParser.Register with a parser initialized with GenericUriParserOptions.DontCompressPath avoids the period trimming, and some other operations that are also undesirable for OpenID. But I cannot register a new parser for existing schemes like HTTP and HTTPS, which I must do for OpenIDs. Another approach I tried was registering my own new scheme, and programming the custom parser to change the scheme back to the standard HTTP(s) schemes as part of parsing: public class MyUriParser : GenericUriParser { private string actualScheme; public MyUriParser(string actualScheme) : base(GenericUriParserOptions.DontCompressPath) { this.actualScheme = actualScheme.ToLowerInvariant(); } protected override string GetComponents(Uri uri, UriComponents components, UriFormat format) { string result = base.GetComponents(uri, components, format); // Substitute our actual desired scheme in the string if it's in there. if ((components & UriComponents.Scheme) != 0) { string registeredScheme = base.GetComponents(uri, UriComponents.Scheme, format); result = this.actualScheme + result.Substring(registeredScheme.Length); } return result; } } class Program { static void Main(string[] args) { UriParser.Register(new MyUriParser("http"), "httpx", 80); UriParser.Register(new MyUriParser("https"), "httpsx", 443); Uri z = new Uri("httpsx://me.yahoo.com/b./c.#adf"); var req = (HttpWebRequest)WebRequest.Create(z); req.GetResponse(); } } This actually almost works. The Uri instance reports https instead of httpsx everywhere -- except the Uri.Scheme property itself. That's a problem when you pass this Uri instance to the HttpWebRequest to send a request to this address. Apparently it checks the Scheme property and doesn't recognize it as 'https' because it just sends plaintext to the 443 port instead of SSL. I'm happy for any solution that: Preserves trailing periods in path segments in Uri.Path Includes these periods in outgoing HTTP requests. Ideally works with under ASP.NET medium trust (but not absolutely necessary).

• SignalR recording when a Web Page has closed

  - by Benjamin Rogers

  I am using MassTransit request and response with SignalR. The web site makes a request to a windows service that creates a file. When the file has been created the windows service will send a response message back to the web site. The web site will open the file and make it available for the users to see. I want to handle the scenario where the user closes the web page before the file is created. In that case I want the created file to be emailed to them. Regardless of whether the user has closed the web page or not, the message handler for the response message will be run. What I want to be able to do is have some way of knowing within the response message handler that the web page has been closed. This is what I have done already. It doesnt work but it does illustrate my thinking. On the web page I have $(window).unload(function () { if (event.clientY < 0) { // $.connection.hub.stop(); $.connection.exportcreate.setIsDisconnected(); } }); exportcreate is my Hub name. In setIsDisconnected would I set a property on Caller? Lets say I successfully set a property to indicate that the web page has been closed. How do I find out that value in the response message handler. This is what it does now protected void BasicResponseHandler(BasicResponse message) { string groupName = CorrelationIdGroupName(message.CorrelationId); GetClients()[groupName].display(message.ExportGuid); } private static dynamic GetClients() { return AspNetHost.DependencyResolver.Resolve<IConnectionManager>().GetClients<ExportCreateHub>(); } I am using the message correlation id as a group. Now for me the ExportGuid on the message is very important. That is used to identify the file. So if I am going to email the created file I have to do it within the response handler because I need the ExportGuid value. If I did store a value on Caller in my hub for the web page close, how would I access it in the response handler. Just in case you need to know. display is defined on the web page as exportCreate.display = function (guid) { setTimeout(function () { top.location.href = 'GetExport.ashx?guid=' + guid; }, 500); }; GetExport.ashx opens the file and returns it as a response. Thank you, Regards Ben

• active_scaffold routing error

  - by Elizabeth Buckwalter

  If you haven't seen my question yesterday, this is my second rails app. The first went nice and smooth, but this one keeps giving me one random error after another. I installed active_scaffold for this app as well as the last app (the first error, instead of using script/install plugin git://active_scaffold repository, I did script/install plugin http://active_scaffold repository.) I didn't want to spell out basic CRUD on minor models. After the install problems, (before I found the http solution from a windows user when I'm on Linux) I thought I'd try out Hobo. Well, Hobo updated actionmailer, actionpack, activerecord, activeresource, and installed rack. Rails isn't even using the updated versions. But as you can see at the bottom of the trace it's using rack. I have a feeling it has something to do with my futzing around with installing Hobo which I uninstalled. Thanks in advanced. [Edit] I had asked the question over at the ActiveScaffold Group the answer (if you don't want to follow the link) was that this line needed to be added to routes: map.resources :modelName, :active_scaffold => true It doesn't entirely answer my question, since the documentation said nothing about changing routes. But, it works.

• "RFC 2833 RTP Event" Consecutive Events and the E "End" Bit

  - by brian_d

  Hello, I can send out a RFC 2833 dtmf event as outlined at http://www.ietf.org/rfc/rfc2833.txt When I do set the E "End" bit, but leave it as 0, I get the following behaviour: If for example keys 7874556332111111145855885#3 were pressed, then ALL events would be sent and show up in a program like wireshark, however only 87456321458585#3 would sound. So the first key (which I figure could be a separate issue) and any repeats of an event (ie 11111) are failing to sound. In section 3.9, figure 2 of the above linked document, they give a 911 example. Here all but the last event have the E bit set. When I set the bit for all numbers, I never get an event to sound. I have thought of a couple possible thing but do not know if they are the reason: 1) figure 2 shows payload types of 96 and 97 sent. I have not nor know how to exactly. In section 3.8, codes 96 and 97 are described as "the dynamic payload types 96 and 97 have been assigned for the redundancy mechanism and the telephone event payload respectively" 2) In section 3.5, "E:", "A sender MAY delay setting the end bit until retransmitting the last packet for a tone, rather than on its first transmission" Does anyone have an idea of how to actually do this? I have also fiddled around with timestamp intervals and the RTP marker. Any help is greatly appreciated. Here is a sample wireshark event capture of the relevant areas: 6590 31.159045000 xx.x.x.xxx --.--.---.-- RTP EVENT Payload type=RTP Event, DTMF Pound # (end) Real-Time Transport Protocol Stream setup by SDP (frame 6225) Setup frame: 6225 Setup Method: SDP 10.. .... = Version: RFC 1889 Version (2) ..0. .... = Padding: False ...0 .... = Extension: False .... 0000 = Contributing source identifiers count: 0 0... .... = Marker: False Payload type: telephone-event (101) Sequence number: 0 Extended sequence number: 65536 Timestamp: 0 Synchronization Source identifier: 0x15f27104 (368210180) RFC 2833 RTP Event Event ID: DTMF Pound # (11) 1... .... = End of Event: True .0.. .... = Reserved: False ..00 0000 = Volume: 0 Event Duration: 2048

• How can I pass latitude and longitude values from UIViewController to MKMapView?

  - by jerincbus

  I have a detail view that includes three UIButtons, each of which pushes a different view on to the stack. One of the buttons is connected to a MKMapView. When that button is pushed I need to send the latitude and longitude variables from the detail view to the map view. I'm trying to add the string declaration in the IBAction: - (IBAction)goToMapView { MapViewController *mapController = [[MapViewController alloc] initWithNibName:@"MapViewController" bundle:nil]; mapController.mapAddress = self.address; mapController.mapTitle = self.Title; mapController.mapLat = self.lat; mapController.mapLng = self.lng; //Push the new view on the stack [[self navigationController] pushViewController:mapController animated:YES]; [mapController release]; //mapController = nil; } And on my MapViewController.h file I have: #import <UIKit/UIKit.h> #import <MapKit/MapKit.h> #import "DetailViewController.h" #import "CourseAnnotation.h" @class CourseAnnotation; @interface MapViewController : UIViewController <MKMapViewDelegate> { IBOutlet MKMapView *mapView; NSString *mapAddress; NSString *mapTitle; NSNumber *mapLat; NSNumber *mapLng; } @property (nonatomic, retain) IBOutlet MKMapView *mapView; @property (nonatomic, retain) NSString *mapAddress; @property (nonatomic, retain) NSString *mapTitle; @property (nonatomic, retain) NSNumber *mapLat; @property (nonatomic, retain) NSNumber *mapLng; @end And on the pertinent parts of the MapViewController.m file I have: @synthesize mapView, mapAddress, mapTitle, mapLat, mapLng; - (void)viewDidLoad { [super viewDidLoad]; [mapView setMapType:MKMapTypeStandard]; [mapView setZoomEnabled:YES]; [mapView setScrollEnabled:YES]; MKCoordinateRegion region = { {0.0, 0.0 }, { 0.0, 0.0 } }; region.center.latitude = mapLat; //40.105085; region.center.longitude = mapLng; //-83.005237; region.span.longitudeDelta = 0.01f; region.span.latitudeDelta = 0.01f; [mapView setRegion:region animated:YES]; [mapView setDelegate:self]; CourseAnnotation *ann = [[CourseAnnotation alloc] init]; ann.title = mapTitle; ann.subtitle = mapAddress; ann.coordinate = region.center; [mapView addAnnotation:ann]; } But I get this when I try to build: 'error: incompatible types in assignment' for both lat and lng variables. So my questions are am I going about passing the variables from one view to another the right way? And does the MKMapView accept latitude and longitude as a string or a number?

• PHP: POST Request to ASP.NET website results in 500 server error when html tags included

  - by RyanJD

  My situation: I need to send text to an ASP.NET web service using POST. The entire page there is a form: <form name="aspnetForm" method="post" action="Discussion.aspx?classroom=lG39il1cotOAGJwiNvmQlIPfwmjikD%2fAHLhjjGInAZQ%3d&amp;Page=Posts&amp;ID=794239&amp;Sort=&amp;SortOrder=" id="aspnetForm"> So, I figured if I sent a POST request to this form with the correct inputs it would work. And, to an extent, it has. The form inputs are as follows: <input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" /> <input type="hidden" name="__EVENTARGUMENT" id="__EVENTARGUMENT" value="" /> <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDw..." /> <input type="hidden" name="__EVENTVALIDATION" id="__EVENTVALIDATION" value="/wEWYQLrt..." /> And a bunch of other inputs. The code I have used is as follows: // grab form info $inputs = extract_form_inputs($discussion['body']); $inputs['__EVENTTARGET'] = 'ctl00$cphMain$ctl01$btnSubmit'; $inputs['ctl00$cphMain$ctl01$tbNickname'] = "Your Instructor"; $inputs['ctl00$cphMain$ctl01$reMessage'] = $message; // submit form $r = request_send($discussion['url'], $inputs); extract_form_inputs does exactly that. $discussion['body'] is the content of the page. $discussion['url'] is the URL of the page. request_send has two arguments: ($url, $post_array). It performs rawurlencode on each element of the array and joins them up as keypairs, in the same way as http_build_query. The request is url encoded properly, sent to the correct page, and works fine until I insert html tags. I have checked - the 'greater than' and 'less than' symbols ('<' and '') are url-encoded properly. However, the server responds with a 500 error. It accepts any other text. Has anyone else come across this sort of problem? Is there some setting on an ASP.NET server that denies html? I can't see this being the case - there is a rich text editor on the website that I am sending requests to. This text editor performs the same request as I am, only I am doing it remotely. The rich text editor sends html to the form - I have checked that, too, using javascript. Note: I do not have the power to modify the ASP.NET server.

• Suggest the best options to me to design the dynamic web interface using PHP MYSQL and AJAX

  - by Krishna

  Hello, I am designing a web interface for a company. I am describing the company's profile: company is currently having 5 branches and planning to extend their branches all over the country. it is an insurance surveying company. they are dealing with 6 Categories in the insurance domain, vide .. Engineering Fire Marine Motor Miscellaneous Risk Inspection and branches named as b1, b2, b3, b4, b5 and Extending. and finally they have contract with 22 companies. For each claim they are assign a unique ID. like contractcompany/category/serialno Ex: take a contracted company names as xxx, sss, zzz. xxx/Engineering/001 sss/Engineering/001 . . . xxx/Enginnering/002 sss/Engineering/002 . . . xxx/Fire/001 sss/Fire/001 . . . xxx/Fire/002 . . . xxx/Fire/002 . . . and so on..... by this way they issue the unique ID for each claim. Finally what i want is developing the interface with PHP mysql and ajax auto generating the unique id for each claim. store full details of the claims with reference to unique id. show all claims in one page, and they can view by branch wise and category wise. send monthly Report (All claims they have given and status of claims) to contract companies. give access to contracted companies, but they can view only their respective claims. Each claim has its own documents. So they can be uploaded by own company users or administrator. these files are associated with unique ID. contracted companies can view files. Give access to branches to enter new claims and update old claims. Administrator can create, update and delete all the claims and their details. Only administrator can grant new users (own company branches / contracted companies) Finally the the panel is completely database driven. Could any body can help. Thanks in advance Kindly do the needful and oblige Thanks and Regards Krishna. P [email protected]

• How to maximize http.sys file upload performance

  - by anelson

  I'm building a tool that transfers very large streaming data sets (possibly on the order of terabytes in a single stream; routinely in the tens of gigabytes) from one server to another. The client portion of the tool will read blocks from the source disk, and send them over the network. The server side will read these blocks off the network and write them to a file on the server disk. Right now I'm trying to decide which transport to use. Options are raw TCP, and HTTP. I really, REALLY want to be able to use HTTP. The HttpListener (or WCF if I want to go that route) make it easy to plug in to the HTTP Server API (http.sys), and I can get things like authentication and SSL for free. The problem right now is performance. I wrote a simple test harness that sends 128K blocks of NULL bytes using the BeginWrite/EndWrite async I/O idiom, with async BeginRead/EndRead on the server side. I've modified this test harness so I can do this with either HTTP PUT operations via HttpWebRequest/HttpListener, or plain old socket writes using TcpClient/TcpListener. To rule out issues with network cards or network pathways, both the client and server are on one machine and communicate over localhost. On my 12-core Windows 2008 R2 test server, the TCP version of this test harness can push bytes at 450MB/s, with minimal CPU usage. On the same box, the HTTP version of the test harness runs between 130MB/s and 200MB/s depending upon how I tweak it. In both cases CPU usage is low, and the vast majority of what CPU usage there is is kernel time, so I'm pretty sure my usage of C# and the .NET runtime is not the bottleneck. The box has two 6-core Xeon X5650 processors, 24GB of single-ranked DDR3 RAM, and is used exclusively by me for my own performance testing. I already know about HTTP client tweaks like ServicePointManager.MaxServicePointIdleTime, ServicePointManager.DefaultConnectionLimit, ServicePointManager.Expect100Continue, and HttpWebRequest.AllowWriteStreamBuffering. Does anyone have any ideas for how I can get HTTP.sys performance beyond 200MB/s? Has anyone seen it perform this well on any environment?

• Incorrect XML produced by SUDS

  - by Ben

  Hi, I am trying to talk to a SOAP web service using SUDS and Python. After lots of messing around learning Python (yes I am new to this) and working out how to use SUDS I have come across a problem. The signature of the web method I am calling, according to suds, is (FWTCaseCreate){ ClassificationEventCode = None Priority = None Title = None Description = None Queue = None DueDate = None AssociatedObject = (FWTObjectBriefDetails){ ObjectID = (FWTObjectID){ ObjectType = None ObjectReference[] = <empty> } ObjectDescription = None Details = None Category = None } Form = (FWTCaseForm){ FormField[] = <empty> FormName = None FormKey = None } Internal = None InteractionID = None XCoord = None YCoord = None } So I use SUDS to create the classes that I want and send it to the method. However I get an error. So I turned logging on and I can see that the XML that is being sent is not correct which is causing a deserialize error. The SOAP package looks like the following <?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlns:ns0="http://www.lagan.com/wsdl/FLTypes" xmlns:ns1="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"> <SOAP-ENV:Header> <wsse:Security> <wsse:BinarySecurityToken>eaadf1ddff99a8</wsse:BinarySecurityToken> </wsse:Security> </SOAP-ENV:Header> <ns1:Body> <ns0:FWTCaseCreate> <ClassificationEventCode> <ClassificationEventCode>2000023</ClassificationEventCode> <Priority>1</Priority> <Title>testing</Title> <Description>testing</Description> <Queue/> <Internal>True</Internal> <XCoord>356570</XCoord> <YCoord>168708</YCoord> </ClassificationEventCode> </ns0:FWTCaseCreate> </ns1:Body> As you can see there is a 'ClassificationEventCode' element around all the other elements, this should not be there. If I cut and paste this xml into SOAPUI and first remove this element and then post it directly to the web service it works successfully. Does anyone have any ideas why this is happening? I guess SUDS thinks that it should be there based on the WSDL. Thanks.
