• ASIHTTPRequest POST splits up header + data?

  - by chris.o.

  Hi, I am using ASIHTTPRequest to POST data to a remote server on iPhone 4.2.1. When I make the following post request to our server, I get a 400 response (I removed the IP address): NSString dataString = @"data1=00&data2=00&data3=00"; ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:<ipremoved>]]]; [request appendPostData:[dataString dataUsingEncoding:NSUTF8StringEncoding]]; [request setRequestMethod:@"POST"]; [request addRequestHeader:@"User-Agent" value:@"iphone app"]; [request addRequestHeader:@"Content-Type" value:@"application/octet-stream"]; request.delegate = self; [request startAsynchronous]; When I send the same data using curl, I receive a 200 response: curl -H "User-Agent: iphone app" -H "Accept:" -H "Content-Type:application/octet-stream" --data-ascii "data1=00&data2=00&data3=00" --location <ipremoved> -v My colleague is stating that, in the failure case, the ASIHTTPRequest requires two socket reads: one for the header and one for the data. Apparently the server is not presently equipped to parse this correctly, so I am trying to work around it. If I setup a proxy between iPhone and my Mac and run Paros (to see packets), the problem goes away. Paros combine the header and data so that it is all acquired by the server in a single socket read. I've tried a few things suggested in other posts including disabling persistent connections, but I am not having any luck. I've also tried doing a ASIHTTPFormRequest, but the server does not like the generated data format. Any suggestions would be appreciated. Thanks.

• Checking if a RoutedEvent has any handlers

  - by AK

  I've got a custom Button class, that always performs the same action when it gets clicked (opening a specific window). I'm adding a Click event that can be assigned in the button's XAML, like a regular button. When it gets clicked, I want to execute the Click event handler if one has been assigned, otherwise I want to execute the default action. The problem is that there's apparently no way to check if any handlers have been added to an event. I thought a null check on the event would do it: if (Click == null) { DefaultClickAction(); } else { RaiseEvent(new RoutedEventArgs(ClickEvent, this));; } ...but that doesn't compile. The compiler tells me that I can't do anything other than += or -= to an event outside of the defining class, event though I'm trying to do this check INSIDE the defining class. I've implemented the correct behavior myself, but it's ugly and verbose and I can't believe there isn't a built-in way to do this. I must be missing something. Here's the relevant code: public class MyButtonClass : Control { //... public static readonly RoutedEvent ClickEvent = EventManager.RegisterRoutedEvent("Click", RoutingStrategy.Bubble, typeof(RoutedEventHandler), typeof(MyButtonClass)); public event RoutedEventHandler Click { add { ClickHandlerCount++; AddHandler(ClickEvent, value); } remove { ClickHandlerCount--; RemoveHandler(ClickEvent, value); } } private int ClickHandlerCount = 0; private Boolean ClickHandlerExists { get { return ClickHandlerCount > 0; } } //... }

• Any way for a class to prevent outside code from declaring variables of its type?

  - by supercat

  Is it possible for a class of exposing a type for function returns, without allowing users of that class to create variables of that type? A couple usage scenarios: A Fluent interface on a large class; a statement like "foo=bar.WithX(5).WithY(9).WithZ(19);" would be inefficient if it had to create three new instances of the class, but could be much more efficient if the WithX could create one instance, and the other statements could simply use it. A class may wish to support a statement like "foo[19].x = 9;" even when foo itself isn't an array, and does not hold the data in class instances that can be exposed to the public; one way to do that is to have foo[19] return a struct which holds a reference to 'foo' and the value '19', and has a member property 'x' which could call "foo.SetXValue(19, 9);" Such a struct could have a conversion operator to convert itself to the "apparent" type of foo[19]. In both of these scenarios, storing the value returned by a method or property into a variable and then using it more than once would cause strange behavior. It would be desirable if the designer of the class exposing such methods or properties could ensure that callers wouldn't be able to use them more than once. Is there any practical way to accomplish that?

• Problem with JSONResult

  - by vikitor

  Hi, I' still newby to this so I'll try to explain what I'm doing. Basically what I want is to load a dropdownlist depending on the value of a previous one, and I want it to load the data and appear when the other one is changed. This is the code I've written in my controller: public ActionResult GetClassesSearch(bool ajax, string phylumID, string kingdom){ IList<TaxClass> lists = null; int _phylumID = int.Parse(phylumID); int _kingdom = int.Parse(kingdom); lists = _taxon.getClassByPhylumSearch(_phylumID, _kingdom); return Json(lists.count); } and this is how I call the method from the javascript function: function loadClasses(_phylum) { var phylum = _phylum.value; $.getJSON("/Suspension/GetClassesSearch/", { ajax: true, phylumID: phylum, kingdom: kingdom }, function(data) { alert(data); alert('no fallo') document.getElementById("pClass").style.display = "block"; document.getElementById("sClass").options[0] = new Option("-select-", "0", true, true); //for (i = 0; i < data.length; i++) { // $('#sClass').addOption(data[i].classID, data[i].className); //} }); } The thing is that just like this it works, I pass the function the number of classes within a selected phylum, and it displays the pclass element, the problem gets when I try to populate the slist with data (which should contain the objects retrieved from the database), because when there is data returned by the database changing return Json(lists) instead of return Json(lists.count) I keep getting the same error: A circular reference was detected while serializing an object of type 'SubSonic.Schema.DatabaseColumn'. I've been going round and round debugging and making tests but I can't make it work, and it is suppossed to be a simple thing, but I'm missing something. I have commented the for loop because I'm not quite sure if that's the way you access the data, because I've not been able to make it work when it finds records. Can anyone help me? Thanks in advance, Victor

• Why does ICEfaces send dispose-window request on page unload when using view-scoped bean?

  - by woflrevo

  in our application ICEfaces always sends a dispose-window request just before navigating to another JSF Page. as much as i understand this should not happen when having org.icefaces.lazyWindowScope set to true and there is no window-scoped bean involved in current request. but it happens on each link and makes our UI less responsive. but we don't have any window-scoped bean in our application. is that a bug in icefaces that the dispose request is sent when using view-scoped beans? Is it possible to disable? ViewScope is defined in JSF not in ICEfaces, it should work without this dispose request i guess... @ManagedBean(name="viewScopeBean") @ViewScoped public class ViewScopeBean { public void doSomething(){ // } } And here the example jsf: <ice:form> <ice:commandButton value="doSomething" action="#{viewScopeBean.doSomething}"/> <h:link outcome="index" value="Link to same page"/> </ice:form> To reproduce do the following using the code above: open firebug's net tab and activate persist option click doSomething-Button click "link to same page" = dispose-window will be send before navigation Dispose Request Parameters: ice.submit.type=ice.dispose.window ice.window=4guthcbue javax.faces.ViewState=-8138151632882151449%3A-6709064564386098402 Environment: ICEfaces-EE 2.0.0.GA ICEpush-EE 2.0.0.GA Mojarra 2.1.1 JRockit 1.6.0_22 WebLogic Server 10.3.4.0 ICEfaces Configuration: org.icefaces.render.auto: true [default] org.icefaces.autoid: true [default] org.icefaces.aria.enabled: true [default] org.icefaces.blockUIOnSubmit: false [default] org.icefaces.compressDOM: false [default] org.icefaces.compressResources: true [default] org.icefaces.connectionLostRedirectURI: /pages/main.jsf org.icefaces.deltaSubmit: false [default] org.icefaces.lazyPush: true [default] org.icefaces.sessionExpiredRedirectURI: /pages/main.jsf org.icefaces.standardFormSerialization: false [default] org.icefaces.strictSessionTimeout: false [default] org.icefaces.windowScopeExpiration = 1000 [default] org.icefaces.mandatoryResourceConfiguration: null [default] org.icefaces.uniqueResourceURLs: true [default] org.icefaces.lazyWindowScope: true [default] org.icefaces.disableDefaultErrorPopups: false [default]

• Django inlineformset validation and delete

  - by Andrew Gee

  Hi, Can someone tell me if a form in an inlineformset should go through validation if the DELETE field is checked. I have a form that uses an inlineformset and when I check the DELETE box it fails because the required fields are blank. If I put data in the fields it will pass validation and then be deleted. Is that how it is supposed to work, I would have thought that if it is marked for delete it would bypass the validation for that form. Regards Andrew Follow up - but I would still appreciate some others opinions/help What I have figured out is that for validation to work the a formset form must either be empty or complete(valid) otherwise it will have errors when it is created and will not be deleted. As I have a couple of hidden fields in my formset forms and they are pre-populated when the page loads via javascript the form fails validation on the other required fields which might still be blank. The way I have gotten around this by adding in a check in the add_fields that tests if the DELETE input is True and if it is it makes all fields on the form not required, which means it passes validation and will then delete. def add_fields(self, form, index) #add other fields that are required.... deleteValue = form.fields['DELETE'].widget.value_from datadict(form.data, form.files, form.add_prefix('DELETE')) if bool(deleteValue) or deleteValue == '': for name, field in form.fields.items(): form.fields[name].required= False This seems to be an odd way to do things but I cannot figure out another way. Is there a simpler way that I am missing? I have also noticed that when I add the new form to my page and check the Delete box, there is no value passed back via the request, however an existing form (one loaded from the database) has a value of on when the Delete box is checked. If the box is not checked then the input is not in the request at all. Thanks Andrew

• weird result with c# winForms array of Lists

  - by jello

  so I'm trying to store values in an array of Lists in C# winForms. In the for loop in which I make the sql statment, everything works fine: the message box outputs a different medication name each time. for (int i = 0; i < numberOfMeds; i++) { queryStr = "select * from biological where medication_name = '" + med_names[i] + "' and patient_id = " + patientID.patient_id; using (var conn = new SqlConnection(connStr)) using (var cmd = new SqlCommand(queryStr, conn)) { conn.Open(); using (SqlDataReader rdr = cmd.ExecuteReader()) { while (rdr.Read()) { medObject.medication_date = (DateTime)rdr["patient_history_date_bio"]; medObject.medication_name = rdr["medication_name"].ToString(); medObject.medication_dose = Convert.ToInt32(rdr["medication_dose"]); medsList[i].Add(medObject); } } conn.Close(); MedicationTimelineClass medObjectx = medsList[i][0] as MedicationTimelineClass; MessageBox.Show(medObjectx.medication_name); } } but then, when I take the message box code out of the loop, meaning that the array of Lists is supposed to be populated, I always get the same value: the last value entered. the same medication name, no matter what number I put between those brackets. It's like if the whole array of Lists is populated with the same data. for (int i = 0; i < numberOfMeds; i++) { queryStr = "select * from biological where medication_name = '" + med_names[i] + "' and patient_id = " + patientID.patient_id; using (var conn = new SqlConnection(connStr)) using (var cmd = new SqlCommand(queryStr, conn)) { conn.Open(); using (SqlDataReader rdr = cmd.ExecuteReader()) { while (rdr.Read()) { medObject.medication_date = (DateTime)rdr["patient_history_date_bio"]; medObject.medication_name = rdr["medication_name"].ToString(); medObject.medication_dose = Convert.ToInt32(rdr["medication_dose"]); medsList[i].Add(medObject); } } conn.Close(); } } MedicationTimelineClass medObjectx = medsList[0][0] as MedicationTimelineClass; MessageBox.Show(medObjectx.medication_name); what's going on here?

• validating wsdl/schema using cxf

  - by SGB

  I am having a hard time getting cxf to validate an xml request that my service creates for a 3rd party. My project uses maven. Here is my project structure Main Module : + Sub-Module1 = Application + sub-Module2 = Interfaces In Interfaces, inside src/main/resources I have my wsdl and xsd. so, src/main/resources + mywsdl.wsdl. + myschema.xsd The interface submodule is listed as a dependency in the Application-sub-module. inside Application sub-module, there is a cxsf file in src/maim/resources. <jaxws:client name="{myTargerNameSpaceName}port" createdFromAPI="true"> <jaxws:properties> <entry key="schema-validation-enabled" value="true" /> </jaxws:properties> </jaxws:client> AND:. <jaxws:endpoint name="{myTargetNameSpaceName}port" wsdlLocation="/mywsdl.wsdl" createdFromAPI="true"> <jaxws:properties> <entry key="schema-validation-enabled" value="true" /> </jaxws:properties> </jaxws:endpoint> I tried changing the "name="{myTargetNameSpaceName}port" to "name="{myEndPointName}port" But to no anvil. My application works. But it just do not validate the xml I am producing that has to be consumed by a 3rd party application. I would like to get the validation working, so that any request that I send would be a valid one. Any suggestions?

• How to pass a random User/Pass (for Basic Authentication) with JMeter?

  - by Pure.Krome

  Hi folks, I'm using JMeter to stress test an API. I've got Basic Authentication set up - seems to be working great. Now, i'm trying to randomize the credentials that JMeter passes across the wire. So, there's two ways I know I can do this. Add a custom HTTP Header (via an HTTP Header Manager Element) and set then value to the random fields (ie. something I've read in from a csv file) Use the HTTP Authorization Manager Element and pass in the username and password there. Now, if I try and use method (1) above, I need to create the following header/data :- Authorization: Basic <some Base64 encoded string in the format username:password> eg. Authorization: Basic OnVzZXIxOnBhc3Mx Kewl. simple. BUT that header value is not getting passed across the wire :( I can add any other header type and it's passed across the wire.. hmm .. ok then .. lets try method (2). Now that works .. but I can only hardcode in the username & password. I can't see how I can pass in a username VARIABLE (ie. ${usernmae} ) or a password VARIABLE (ie. ${password} ).... If it's hardcoded, then the server correctly replies with the correct page/data. so .. can someone please help?

• How can parallelism affect number of results?

  - by spender

  I have a fairly complex query that looks something like this: create table Items(SomeOtherTableID int,SomeField int) create table SomeOtherTable(Id int,GroupID int) with cte1 as ( select SomeOtherTableID,COUNT(*) SubItemCount from Items t where t.SomeField is not null group by SomeOtherTableID ),cte2 as ( select tc.SomeOtherTableID,ROW_NUMBER() over (partition by a.GroupID order by tc.SubItemCount desc) SubItemRank from Items t inner join SomeOtherTable a on a.Id=t.SomeOtherTableID inner join cte1 tc on tc.SomeOtherTableID=t.SomeOtherTableID where t.SomeField is not null ),cte3 as ( select SomeOtherTableID from cte2 where SubItemRank=1 ) select * from cte3 t1 inner join cte3 t2 on t1.SomeOtherTableID<t2.SomeOtherTableID option (maxdop 1) The query is such that cte3 is filled with 6222 distinct results. In the final select, I am performing a cross join on cte3 with itself, (so that I can compare every value in the table with every other value in the table at a later point). Notice the final line : option (maxdop 1) Apparently, this switches off parallelism. So, with 6222 results rows in cte3, I would expect (6222*6221)/2, or 19353531 results in the subsequent cross joining select, and with the final maxdop line in place, that is indeed the case. However, when I remove the maxdop line, the number of results jumps to 19380454. I have 4 cores on my dev box. WTF? Can anyone explain why this is? Do I need to reconsider previous queries that cross join in this way?

• overriding enumeration base type using pragma or code change

  - by vprajan

  Problem: I am using a big C/C++ code base which works on gcc & visual studio compilers where enum base type is by default 32-bit(integer type). This code also has lots of inline + embedded assembly which treats enum as integer type and enum data is used as 32-bit flags in many cases. When compiled this code with realview ARM RVCT 2.2 compiler, we started getting many issues since realview compiler decides enum base type automatically based on the value an enum is set to. http://www.keil.com/support/man/docs/armccref/armccref_Babjddhe.htm For example, Consider the below enum, enum Scale { TimesOne, //0 TimesTwo, //1 TimesFour, //2 TimesEight, //3 }; This enum is used as a 32-bit flag. but compiler optimizes it to unsigned char type for this enum. Using --enum_is_int compiler option is not a good solution for our case, since it converts all the enum's to 32-bit which will break interaction with any external code compiled without --enum_is_int. This is warning i found in RVCT compilers & Library guide, The --enum_is_int option is not recommended for general use and is not required for ISO-compatible source. Code compiled with this option is not compliant with the ABI for the ARM Architecture (base standard) [BSABI], and incorrect use might result in a failure at runtime. This option is not supported by the C++ libraries. Question How to convert all enum's base type (by hand-coded changes) to use 32-bit without affecting value ordering? enum Scale { TimesOne=0x00000000, TimesTwo, // 0x00000001 TimesFour, // 0x00000002 TimesEight, //0x00000003 }; I tried the above change. But compiler optimizes this also for our bad luck. :( There is some syntax in .NET like enum Scale: int Is this a ISO C++ standard and ARM compiler lacks it? There is no #pragma to control this enum in ARM RVCT 2.2 compiler. Is there any hidden pragma available ?

• Web service SSL handshake fails in production environment unless SSL debugging enabled

  - by JST

  Scenario: calling a client web service over SSL (https) with mutual SSL authentication. Different service endpoint URLs and certs (both keystore and truststore) for test vs. production environments. Both test and production environments run tomcat / JBoss clustered. Production environment has load balancing / BigIP, runs Blade and non-Blade machines. Truststore is set (using -Djavax.net.ssl.trustStore=value) at startup. Keystore is set using System.setProperty("javax.net.ssl.keyStore", "value") in Java code. Web service call made using Axis2. All works fine in test environment, but when we moved to production environment (6 servers), it appears certs are not being forwarded for the handshake. Here's what we've done: in test environment, handshake using test versions of certs has been working all along, with no ssl debugging enabled confirmed in test environment that handshake with client production endpoint succeeds (production certs, both ours and theirs, are fine) -- this was done using -Djavax.net.debug=handshake,ssl confirmed that the error condition occurs on all 6 production servers took one server out of the cluster, turned on ssl debugging for just that one (with a restart), hit it directly, handshake works! switched to a different server without the debugging turned on, handshake error condition occurs turned debugging on on that second server (with a restart), hit it directly, handshake works! From the evidence, it seems like somehow the debugging being enabled causes the certificates to be properly retrieved/conveyed, although that makes no sense! I wonder whether somehow the enabled debugging makes the system pay attention to the System.setProperty call, and ignore it otherwise. However, in local and test environments, handshake worked without debugging enabled. Do I maybe need to be setting keystore on server startup like I'm setting truststore? Have been avoiding that because the keystore will differ for each of our test environments (16 of them).

• Shopify: Replacing Product Radio Buttons With Dropdown Select

  - by Wade D Ouellet

  Hi, With Shopify I am trying to alter my product template to display a dropdown select list instead of radio buttons for my product variants. I managed to do this but when you try and add a product to the cart from the list it says, "No variant ID was passed." Here is the code for their radio buttons: <ul id="product-variants"> {% for variant in product.variants %} <li> {% if variant.available %} <input type="radio" name="id" value="{{variant.id}}" id="radio_{{variant.id}}" style="vertical-align: middle;" {%if forloop.first%} checked="checked" {%endif%} /> <label for="radio_{{variant.id}}"><span class="sku">{{ variant.sku }}</span> {%if variant.title != 'Default' %}{{ variant.title }} for {%endif%} <span class="price">{{ variant.price | money_with_currency }}</span></label> {% else %} <del style="margin-left: 26px">{{ variant.title }}</del>&nbsp;<span>Sold Out!</span> {% endif %} </li> {% endfor %} </ul> Here is the code for my dropdown select at this point: <select id="product-variants"> {% for variant in product.variants %} <li> {% if variant.available %} <option value="{{variant.id}}" selected="selected"><span class="sku">{{ variant.sku }}</span> {%if variant.title != 'Default' %}{{ variant.title }} for {%endif%} <span class="price">{{ variant.price | money_with_currency }}</span></option> {% else %} <del style="margin-left: 26px">{{ variant.title }}</del>&nbsp;<span>Sold Out!</span> {% endif %} </li> {% endfor %} </select> Thanks, Wade

• how to show avg of employees salary in a NSTextField using NSArrayController and cocoa bindings

  - by Miraaj

  Hi all, I am new to cocoa bindings so I tried to make a simple application which will simply calculate avg of employees salary and display it in a text field, using cocoa bindings. I followed these steps: Made the model class : Person with one property for now - @property (readwrite, assign) int salary; In the application delegate class I initialized a mutable array : personArray with certain objects like this: Person *person1 = [[Person alloc] init]; person1.salary = 5000; Person *person2 = [[Person alloc] init]; person2.salary = 15000; Person *person3 = [[Person alloc] init]; person3.salary = 7000; Person *person4 = [[Person alloc] init]; person4.salary = 9000; Person *person5 = [[Person alloc] init]; person5.salary = 11000; personArray= [[NSMutableArray alloc] initWithObjects:person1, person2, person3, person4, person5,nil]; In IB I dropped a NSArrayController object, set its mode as Class - Person, added key salary in attribute pane. Then in bindings pane, binded contents array to ApplicationDelegate class with model key path set to self.personArray. Dropped a NSTextField on window. Binded its value to ArrayController object. Assigned controller key as - arrangedObjects. Assigned Model key path to @avg.salary When I executed the application I found no value being displayed in the text field. Can anyone suggest me where I may be wrong? Thanks, Miraaj

• Mark assembly App_licenses.dll with AssemblyVersion (FxCop CA1016 rule)

  Hello everyone, I'm trying to fulfil FxCop's rules in my web site. Since I use some Infragistics controls I have a licenses.licx file that turns into a "app_licenses.dll" assembly after publication. The problem is that this app_licenses.dll assembly does not comply with rule CA1016 (MarkAssembliesWithAssemblyVersion), and I should add an AssemblyVersion attribute to 'App_Licenses.dll'. I found I can add an AssemblyInfo file to my web site and then reference it from the web.config file as following: <compilers> <compiler language="c#;cs;csharp" extension=".cs" compilerOptions="C:\....\AssemblyInfo.cs" type="Microsoft.CSharp.CSharpCodeProvider,System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" warningLevel="4"> <providerOption name="CompilerVersion" value="v3.5" /> <providerOption name="WarnAsError" value="false" /> </compiler> </compilers> AssemblyInfo.cs contains: using System; using System.Reflection; using System.Runtime.InteropServices; using System.Resources; [assembly: AssemblyVersion("1.0.0.0")] [assembly: AssemblyFileVersion("1.0.0.0")] [assembly: NeutralResourcesLanguageAttribute("es-ES")] NeutralResourcesLanguageAttribute worked for another auto-generated dll in the web site (app_GlobalResources.dll) for another FxCop rule, but app_licenses.dll seems to ignore the assembly info and still pops up the same CA1016 error. Any help would be much appreciated.

• XAML Deserialization problem

  - by mrwayne

  Hi, I have a block of XAML of which i'm trying to deserialize. For arguments sake lets say it looks like below. <NS:SomeObject> <NS:SomeObject.SomeProperty> <NS:SomeDifferentObject SomeOtherProp="a value"/> </NS:SomeObject.SomeProperty> </NS:SomeObject> Of which i deserialise using the following code. XamlReader.Load( File.OpenRead( @"c:\SomeFile.xaml")) I have 2 solutions, one i use Unit Testing, and another i have for my web application. When i'm using the unit testing solution, it deserializes fine and works as expected. However, when i try to deserialize using my other project i keep getting an exception like the following. 'NameSpace.SomeObject' value cannot be assigned to property 'SomeProperty' of object 'NameSpace.SomeObject'. Object of Type 'NameSpace.SomeObject' cannot be converted to type 'NameSpace.SomeObject'. It's as if it is getting confused or instantiating 2 different types of objects? Note, i do not have similarly named classes or any sort of namespace conflict. The same codes executes fine in one solution and not the other. The same project files are referenced in both. Please help!

• jQuery autocomplete: taking JSON input and setting multiple fields from single field

  - by Sly

  I am trying to get the jQuery autocomplete plugin to take a local JSON variable as input. Once the user has selected one option from the autocomplete list, I want the adjacent address fields to be autopopulated. Here's the JSON variable that declared as a global variable in the of the HTML file: var JSON_address={"1":{"origin":{"nametag":"Home","street":"Easy St","city":"Emerald City","state":"CA","zip":"9xxxx"},"destination":{"nametag":"Work","street":"Factory St","city":"San Francisco","state":"CA","zip":"94104"}},"2":{"origin":{"nametag":"Work","street":"Umpa Loompa St","city":"San Francisco","state":"CA","zip":"94104"},"destination":{"nametag":"Home","street":"Easy St","city":"Emerald City ","state":"CA","zip":"9xxxx"}}}</script> I want the first field to display a list of "origin" nametags: "Home", "Work". Then when "Home" is selected, adjacent fields are automatically populated with Street: Easy St, City: Emerald City, etc. Here's the code I have for the autocomplete: $(document).ready(function(){ $("#origin_nametag_id").autocomplete(JSON_address, { autoFill:true, minChars:0, dataType: 'json', parse: function(data) { var rows = new Array(); for (var i=0; i<=data.length; i++) { rows[rows.length] = { data:data[i], value:data[i].origin.nametag, result:data[i].origin.nametag }; } return rows; } }).change(function(){ $("#street_address_id").autocomplete({ dataType: 'json', parse: function(data) { var rows = new Array(); for (var i=0; i<=data.length; i++) { rows[rows.length] = { data:data[i], value:data[i].origin.street, result:data[i].origin.street }; } return rows; } }); }); }); So this question really has two subparts: 1) How do you get autocomplete to process the multi-dimensional JSON object? (When the field is clicked and text entered, nothing happens - no list) 2) How do you get the other fields (street, city, etc) to populate based upon the origin nametag sub-array? Thanks in advance!

• javascript form validation - positioning

  - by Holian

  Dear Masters! I have little snippet for validatin' my form. I need help to position the error messages, because now all message appear in the filed, so the user can't see it, and so its very annoying. $(document).ready(function() { jQuery.validator.addMethod("lettersonly", function(value, element) { return this.optional(element) || /^[a-zoöüóúéáuí ]+$/i.test(value); }, "<?php echo $lettersonly; ?>"); $("#regval").validate({ rules: { name: { required: true, minlength: 5, maxlength:30, lettersonly: true }, nick: { required: true, minlength: 3, maxlength:12 }, pass1: { required: true, minlength: 5 }, pass2: { required: true, minlength: 5, equalTo: "#pass1" }, messages: { full: { required: ".....", minlength: "....", maxlength: "...." }, nick: { required: "....", minlength: "....", maxlength: "...." }, pass1: { required: "....", minlength: "..." }, pass2: { required: "....", minlength: "....", equalTo: "...." }, }); }); </script>

• URL Encoding using C#

  - by masfenix

  I have an application which I've developed for a friend. It sends a POST request to the VB forum software and logs someone in (with out setting cookies or anything). Once the user is logged in I create a variable that creates a path on their local machine. c:\tempfolder\date\username The problem is that some usernames are throwing "Illegal chars" exception. For example if my username was mas|fenix it would throw an exception.. Path.Combine( _ Environment.GetFolderPath(System.Environment.SpecialFolder.CommonApplicationData), _ DateTime.Now.ToString("ddMMyyhhmm") + "-" + form1.username) I don't want to remove it from the string, but a folder with their username is created through FTP on a server. And this leads to my second question. If I am creating a folder on the server can I leave the "illegal chars" in? I only ask this because the server is Linux based, and I am not sure if Linux accepts it or not.. EDIT: It seems that URL encode is NOT what I want.. Here's what I want to do: old username = mas|fenix new username = mas%xxfenix Where %xx is the ASCII value or any other value that would easily identify the character.

• Hidden div height (changing my advice)

  - by fudgey

  Ok, I was going to answer someone's question here on SO about why their script wasn't working. They loaded content into a hidden div, then got the height so they could animate the wrapping div. But I always try to test the code I provide. So I made this demo to prove it to them. So, umm, have I entered the twilight zone or am I dreaming right now? pinches self OUCH! I tried that demo in Firefox, IE and Chrome and both methods return the same value. Firebug says zero! I rebooted my computer and I even changed the code a bit (removed the height function) and tried it with jQuery 1.3.2 and it still worked! I know hidden elements USED to return a zero value. Even this SO Answer is giving the advice I would have! So I guess my question is... did I miss something or are we giving bad advice?
