• Mobile Safari Geolocation API Issues

  - by sph

  Hi, since Mobile Safari's Geolocation API should be an implementation of the W3C Geolocation API I found some bugs. I was wondering if anybody noticed the same. As specified in the W3C Geolocation API the PositionCallback returns a Position object, which contains a Coordinates object. In this object all attributes are of type double. Using navigator.geolocation.getCurrentPosition and checking the Position object in the successCallback the accuracy attribute is always an object, but should be a double. The heading attribute is always -1 when testing in the iPhone simulator, but should be null or between 0 and 360. 2. Setting the options parameter for navigator.geolocation.watchPosition or navigator.geolocation.getCurrentPosition as specified in the W3C Geolocation API has no effect. No matter what is set as the timeout value, the win callback is called every 10 seconds. For example setting the timeout=1000 should immediately call either the successCallback or errorCallback. Thanks

• How to pass parameters in jquery

  - by Priyanka

  Hello. I am supposed to submit 2values called str and name to another page.But only 1value is getting returned in the next page.When i include name and on next page if i say print_r($_POST),then even the first value is not getting printed. I have written a fuction as follows,which works because there is only one parameter. function sendValue(str) { $.post( "newsletter/subscribe.php", //Ajax file { sendValue: str }, function(data){ $('#display').html(data.returnValue); }, "json" ); } But if i pass 2values in that function and in $.post,i do sendValue:str,name then i am not getting even 1value. Please help me.

• Castle Windsor config pointing to connectionStrings section in web.config

  - by Georgia Brown

  I want to inject a connection string into my repository but ideally, I want this connection string to be in my web.config connectionStrings section rather than in my windsor config. Is this possible? I know I can use the fluent interface and achieve this easily but my bosses want an xml config file. I also know that I can define a property and use that in my windsor config to pass the parameter in, but I have other code that reads the connectionstring from the web.config directly and do not really want two places with the same connectionString.

• Csharp component which generates fragmens with highlights for diffs for 2 strings

  - by MicMit

  I need C# equivalent ( ideally open source ) which is similar to Delphi DLL. I am currently using the wrapper ( C# syntax is provided , but it is a call from a different language ) zdiff( string ref str1, string ref str2, int range , int trim ) it calls inside str1 = GetHiDiff(@str1,1,trim) str2 = GetHiDiff(@str1,2,trim) where function GetHiDiff(s:pchar; sIndex:integer; wtrim:integer): pchar; stdcall; What it does it returns a left fragment html of str1 and a right html fragment of str2 with diffs highlighted as strings are passed by reference. Range parameter determines the size of html fragment. Not sure what trim 0 does.

• Session timeout issue

  - by Kumar

  I have a role based ASP.NET C# web application in which I am putting the menu object inside a session and I have a session timeout configured in the web.config as below: <forms defaultUrl="Home.aspx" loginUrl="Login.aspx" name=".ASPXFORMSAUTH" timeout="10"></forms> I first logged into the system as an employee and waited until the session expires and then when I click a link in the menu I am being rightly redirected to the login page with the ReturnUrl parameter. Now when I try to login to the system as an administrator I am still seeing the employee menu and not the admin menu. The method which loads the menu 1st checks to see if the menu session object is not null if so loads the menu from the session if not then it builds the menu and put it into session. So when the system timesout the menu session object is not being cleared. How can I fix this?

• iPhone link to map directions using string "current location" not lat and lng for saddr

  - by Nick

  I know there are numerous questions about how to construct a sharedApplication link to the maps app specifying the start and end address with coordinates. I've got that working no problem. Has anyone found a way to link with a source address generically specified as "current location". I ask because the scenario I'm working on having Core Location or a UIMapView would only be necessary in order to determine the user location prior to handing off to the map app where the user locating would seem to just happen again. I've tried throwing UTF8'd "Current Location" and "[Current Location]" into the saddr parameter which amusingly starts from Current Montana. I've also tried simply excluding the saddr param. I know this is often tread territory but this particular situation wasn't covered by anything I found searching here or on mapki. Before I add the core location code I just wanted to make sure there wasn't a more limited way to tackle this. Thanks

• how do arguments work with dojo.connect?

  - by sprugman

  I've read the docs, but I must be missing something. I've got a grid, I want to connect to the event that fires when the column headers are clicked for sorting, thus: dojo.addOnLoad(function(){ var grid = dijit.byId("grid"); dojo.connect(grid, "setSortInfo", 'afterSort'); }); function afterSort() { console.info('after sort'); } That works fine as far as it goes. I know the setSortInfo method has an argument which is the column number. How do I get that value? I've tried putting a parameter in the sig for afterSort to no avail. The docs say "the method receives the same arguments as the event", but where are they???

• Problem with Apache Commons Id UUID Version 1 generation

  - by Pekka Mattila

  My problem is to generate version 1 UUIDs. We use Jetty 6.x, Maven (to start Jetty among other things) and Apache Commons ID (to generate UUID version 1 from the current time). Apache Commons ID requires a configuration file that is told to the JVM, using a parameter, e.g. 'org.apache.commons.id.uuid.config.resource.filename=commons-id-uuid.xml'. I checked the Apache Commons ID code and it tries to find the file from the classpath. Jetty's documentation states that WEB-INF/lib and WEB-INF/classes are in the classpath. The 'commons-id-uuid.xml' can be found from the deployed war file from the root of WEB-INF/classes directory but Jetty cannot load it: Message: java.lang.RuntimeException: java.lang.IllegalStateException: commons-id-uuid.xml loaded as system resource is null Jetty was started using the following command: mvn jetty:run -Dorg.apache.commons.id.uuid.config.resource.filename=commons-id-uuid.xml Any idea what is going wrong? We just need to generate UUID version 1 identifiers. Any suggestions?

• How to use/manipulate return value from nested boost::bind

  - by JQ

  I have two functions: 1. A & DataSource(); 2. void DataConsumer( A * ); What I want to achieve: Using one statement to assemble them into one functor. I have tried: 1. boost::function< void() func( boost::bind( DataConsumer, & boost::bind( DataSource ) ) ); certainly it didn't work, compiler says it can not convert 'boost::_bi::bind_t ' to 'A *' 2. boost::function< void() func( boost::bind( DataConsumer, boost::addressof( boost::bind( DataSource ) ) )); compiler says cannot convert parameter 1 from 'boost::_bi::bind_t' to 'A &' Question: how to use return value from the nested boost::bind ? or if you want to use boost::lambda::bind.

• Regular expression in BASH

  - by Ryan

  Hello everyone, I was hoping someone could answer my quick question as I am going nuts! I have recently started learning regular expressions in my Java programming however am a little confused how to get certain features to work correctly directly in BASH. For example, the following code is not working as I think it should. echo 2222 | grep '2\{2\}' I am expecting it to return: 22 I have tried variations of it including: echo 2222 | grep '2{2}' echo 2222 | grep -P '2\{2\}' echo 2222 | grep -E '2\{2\}' However I am completely out of ideas. I'm sure this is a simple parameter / syntax fix and would love some help! P.S I've done tons of googling and every reference I find does not work in BASH; regex's can run on so many different platforms and engines =/

• How can I use a value from a session variable as part of the group name in signalR

  - by user1844734

  Hi I am trying to set up signalR to distribute messages to web users the problem is that the one site holds different 'areas' and also 'user types'. The Area is decided when the user visits the site by passing a url parameter, this is then stored in a session variable, The 'user type' is by default not logged in then changed when the user logs in to there user type (returned from a webservice) and stored in a User object. My aim was to connect to the hub using signalR when the user visits the site and add the users connectionId to a groupname, using the 'area id' from the session and the 'user type id' from the User object in the context. The problem I am having is that I can obtain the user id but when it comes to the area id signalR cannot access the session. I understand the reasoning behind not allowing the session available in signalR but does any one know if there is a way to enable this or an alternative way that I can gain access to the users area so that I can create these unique groups.

• how to write re-usable views in django?

  - by rz

  These are the techniques that I use regularly to make my views reusable: take the template_name as an argument with a default take an optional extra_context which defaults to empty {} right before the template is rendered the context is updated with the extra_context for further re-usability, call any callable in extra_context.values() whenever the view deals with a queryset, there is a queryset argument with a default whenever the view needs a particular object from the ORM, it attempts to fetch it using any "id" parameter in several ways (e.g. as a slug, as a database id) (this may be a bad practice...) First, Should I add anything to my list? Should I remove anything from my list? The items accommodates a large number of cases. However, whenever an app extends a model of another in some way (e.g. adding a field or changing the behavior in some way) I end up writing my own views and only reusing the model. Is this normal?

• How to implement exception chaining in PHP

  - by Josef Sábl

  Constructor for PHP's exception has third parameter, documentation says: $previous: The previous exception used for the exception chaining. But I can't make it work. My code looks like this: try { throw new Exception('Exception 1', 1001); } catch (Exception $ex) { throw new Exception('Exception 2', 1002, $ex); } I expect Exception 2 to be thrown and I expect that it will have Exception 1 attached. But all I get is: Fatal error: Wrong parameters for Exception([string $exception [, long $code ]]) in ... What am I doing wrong?

• Registering NUnit DynamicMock Instances in a UnityContainer

  - by Phil

  I'm somewhat new to Unity and dependency injection. I'm trying to write a unit test that goes something like this: [Test] public void Test() { UnityContainer container = new UnityContainer(); DynamicMock myMock = new DynamicMock(typeof(IMyInterface)); container.RegisterInstance(typeof(IMyInterface), myMock.MockInstance); //Error here // Continue unit test... } When this test executes, the container throws an ArgumentNullException inside the RegisterInstance method with the message Value cannot be null. Parameter name: assignmentValueType. The top line of the stack trace is at Microsoft.Practices.Unity.Utility.Guard.TypeIsAssignable(Type assignmentTargetType, Type assignmentValueType, String argumentName). Why can't I register a MockInstance with the UnityContainer, and how do I work around this?

• Getting a JPEG image from a hex string in XML.

  - by Jesse Knott

  Well here goes, I am trying to collect a picture that is encoded as a hex string in an xml file. I have been looking all over for the answer to this and have not been able to find it any where. Here is what I have now. byte[] bytes = Convert.FromBase64String(FilterResults("PHOTOGRAPH")); MemoryStream mem = new MemoryStream(bytes); Image bmp2 = Image.FromStream(mem); return bmp2; The FilterResults function just returns the string from the XML. I am able to get the string of characters and convert it into a byte[] but as soon as I execute the Image.FromStream(mem) I get an "Parameter Incorrect" error. Any ideas?

I tried adding a META-INF folder to the bin-root, and in various other places, but with no success. How do I specify in this case the location of a custom WSDL? Thanks!

• What happens when Npgsql connection pool reaches Max

  - by ClearCarbon

  Both the name of the connection string parameter and this blog post - http://fxjr.blogspot.co.uk/2010/04/npgsql-connection-pool-explained.html - lead me to believe that Npgsql wont exceed the MaxPoolSize value set in the connection string. However the docs (http://npgsql.projects.postgresql.org/docs/manual/UserManual.html) say "Max size of connection pool. Pooled connections will be disposed of when returned to the pool if the pool contains more than this number of connections. Default: 20" This suggests that the pool can actually grow larger than MaxPoolSize and it is in fact just a level at which Npgsql starts to aggressively remove connections from the pool as soon as they are returned. I've been searching to try and find an answer but I can find out exactly what happens when you reach MaxPoolSize. Anyone else know? edit: I should add we are using Npgsql 2.0.6.0 due to another dependency being supported only up to that version.

• Displaying large file in JTextArea.

  - by Sathish Gopal

  Hi All, I'm currently working in Swing UI Assignment. This work involves showing large file content in JTextArea. The file size can be as large as 2 GB. My initial idea is to lazily load content from the file, say 1 MB of content will be shown to the user. As the user scrolls i will retrieve the next 1 MB of content to be shown. All these operation will be happening in background thread (Swing Worker). I looked at the JTextArea API, the method insert takes String and int(position of the insert) as the parameter. This will suffice, but i'm worried about performance, because the content (1 MB at a time) retrieved will have to be converted to String object. Is there any other work around or any other alternative/better solution for this.

• Function returns CSV File: How to go about checking it ?

  - by Rachel

  I am doing something like: $outputFile = getCurrentDBSnapshot($data); where $data is the resource stream that am passing in, basically from command prompt am passing an file and am opening it using fopen for writing with 'w+' permissions, now getCurrentDBSnapshot would get the current state of a table and would update the $data csv file, so basically $outputFile would be updated with the current state of database table, now I want to var_dump or print the value of $outputFile to see the data present into it. But when I do $this->fout = fopen($outputFile,'r') or die('Cannot open file'); $test = fgetcsv($outputFile,5000,":"); var_dump($test); It gives me an error saying that it expects parameter 1 to be a string type and am passing resource. My goal to see the contains of $outputFile and so my question is that How can I see the contains present in $outputFile or how can I see what getcurrentDBSnapshot function is returning me ?

• Copy Structure To Another Program

  - by Steven

  Long story, long: I am adding a web interface (ASPX.NET: VB) to a data acquisition system developed with LabVIEW which outputs raw data files. These raw data files are the binary representation of a LabVIEW cluster (essentially a structure). LabVIEW provides functions to instantiate a class or structure or call a method defined in a .NET DLL file. I plan to create a DLL file containing a structure definition and a class with methods to transfer the structure. When the webpage requests data, it would call a LabVIEW executable with a filename parameter. The LabVIEW code would instantiate the structure, populate the structure from the data file, then call the method to transfer the data back to the website. Long story, short: How do you recommend I transfer (copy) an instance of a structure from one .NET program to a VB.NET program? Ideas considered: sockets, temp file, xml file, config file, web services, CSV, some type of serialization, shared memory

• Xpath and parameters

  - by Daniel

  I am relatively new to XSL and I think this is a basic question. So I better get my apologies in early! Basically, I would like to use a value-of function. This will be in a template and I would like to pass part of the xpath as a parameter. <xsl:variable name="TEST_VAR">"h:elementA/elementB"</xsl:variable> ... and then use the variable (or passed in param) as all (or part) of the xpath: <xsl:element name="transformedElement"><xsl:value-of select=$TEST_VAR/></xsl:element> I would really like to have the xpath to be a mixture of string literals and the vlue of TEST_VAR. Thanks in advance
