  • Simple search form passing the searched string through GET

    - by Brian Roisentul
    Hi, I'd like my Search form to return the following url after submit: /anuncios/buscar/the_text_I_searched My form is the following: <% form_for :announcement, :url => search_path(:txtSearch) do |f| %> <div class="searchBox" id="basic"> <%= text_field_tag :txtSearch, params[:str_search].blank? ? "Busc&aacute; tu curso r&aacute;pido y f&aacute;cil." : params[:str_search], :maxlength=> 100, :class => "basicSearch_inputField", :onfocus => "if (this.value=='Busc&aacute; tu curso r&aacute;pido y f&aacute;cil.') this.value=''", :onblur => "if(this.value=='') { this.value='Busc&aacute; tu curso r&aacute;pido y f&aacute;cil.'; return false; }" %> <div class="basicSearch_button"> <input type="submit" value="BUSCAR" class="basicSearch_buttonButton" /> <br /><a href="#" onclick="javascript:jQuery('#advance').modal({opacity:60});">Busqueda avanzada</a> </div> </div> <% end %> My routes' line for search_path is this: map.search '/anuncios/buscar/:str_search', :controller => 'announcements', :action => 'search' Well, this will work if I manually type the url I want in the brower, but definitely, if you look at the form's url, you'll find a ":txtSearch" parameter, which is not giving me the actual value of the text field when the form is submitted. And that's what I'd like to get! Could anybody help me on this?

  • Creating rapid function overloads in C++

    - by DeadMG
    template<typename Functor, typename Return, typename Arg1, typename Arg2, typename Arg3, typename Arg4, typename Arg5, typename Arg6, typename Arg7, typename Arg8, typename Arg9, typename Arg10> class LambdaCall : public Instruction { public: LambdaCall(Functor func ,unsigned char constructorarg1 ,unsigned char constructorarg2 ,unsigned char constructorarg3 ,unsigned char constructorarg4 ,unsigned char constructorarg5 ,unsigned char constructorarg6 ,unsigned char constructorarg7 ,unsigned char constructorarg8 ,unsigned char constructorarg9 ,unsigned char constructorarg10) : arg1(constructorarg1) , arg2(constructorarg2) , arg3(constructorarg3) , arg4(constructorarg4) , arg5(constructorarg5) , arg6(constructorarg6) , arg7(constructorarg7) , arg8(constructorarg8) , arg9(constructorarg9) , arg10(constructorarg10) , function(func) {} void Call(State& state) { state.Push<Return>(func(*state.GetRegisterValue<Arg1>(arg1) ,*state.GetRegisterValue<Arg1>(arg1) ,*state.GetRegisterValue<Arg2>(arg2) ,*state.GetRegisterValue<Arg3>(arg3) ,*state.GetRegisterValue<Arg4>(arg4) ,*state.GetRegisterValue<Arg5>(arg5) ,*state.GetRegisterValue<Arg6>(arg6) ,*state.GetRegisterValue<Arg7>(arg7) ,*state.GetRegisterValue<Arg8>(arg8) ,*state.GetRegisterValue<Arg9>(arg9) ,*state.GetRegisterValue<Arg10>(arg10) )); } Functor function; unsigned char arg1; unsigned char arg2; unsigned char arg3; unsigned char arg4; unsigned char arg5; unsigned char arg6; unsigned char arg7; unsigned char arg8; unsigned char arg9; unsigned char arg10; }; Then again for every possible number of arguments I want to support, and again for void returns. Any way to do this faster?

  • eclipse stuck at running program

    - by user1434388
    This is the picture after I end task the eclipse. My Android Program has no errors, and before this problem it was all fine. It happened when I added some code into my program. It gets stuck after I click the run button. This also happens when I run my handphone for debugging the program. Other programs are all working fine, only one is stuck. When I try to remove and import it again seem there is a classes.dex file which I cannot delete, I have to restart my computer for it to allow to delete and I have to force the program to close. I have searched at this website and they said keep open the emulator but it doesn't work for me. below is the connecting coding that i added. //check internet connection private boolean chkConnectionStatus(){ ConnectivityManager connMgr = (ConnectivityManager) this.getSystemService(Context.CONNECTIVITY_SERVICE); final android.net.NetworkInfo wifi = connMgr.getNetworkInfo(ConnectivityManager.TYPE_WIFI); final android.net.NetworkInfo mobile = connMgr.getNetworkInfo(ConnectivityManager.TYPE_MOBILE); if( wifi.isAvailable() ){ return true; } else if( mobile.isAvailable() ){ return true; } else { Toast.makeText(this, "Check your internet" , Toast.LENGTH_LONG).show(); return false; } }

  • Disable specific dates in jquery

    - by rvdb86
    I am using the jquery date picker found here: http://www.kelvinluck.com/assets/jquery/datePicker/v2/demo/datePickerStartEnd.html that allows the user to pick a start and end date. However I want to be able to disable specific dates. I tried to implement the code found here: stackoverflow.com/questions/501943/can-the-jquery-ui-datepicker-be-made-to-disable-saturdays-and-sundays-and-holida that discusses disabling national holidays. Here is my complete code: $(function() { $('.date-pick').datePicker({ beforeShowDay: nationalDays}) // $(".selector").datepicker({ beforeShowDay: nationalDays}) var natDays = [ [1, 26, 'au'], [2, 6, 'nz'], [3, 17, 'ie'], [4, 27, 'za'], [5, 25, 'ar'], [6, 6, 'se'], [7, 4, 'us'], [8, 17, 'id'], [9, 7, 'br'], [10, 1, 'cn'], [11, 22, 'lb'], [12, 12, 'ke'] ]; function nationalDays(date) { for (i = 0; i < natDays.length; i++) { if (date.getMonth() == natDays[i][0] - 1 && date.getDate() == natDays[i][1]) { return [false, natDays[i][2] + '_day']; } } return [true, '']; } $('#start-date').bind( 'dpClosed', function(e, selectedDates) { var d = selectedDates[0]; if (d) { d = new Date(d); $('#end-date').dpSetStartDate(d.addDays(1).asString()); } } ); $('#end-date').bind( 'dpClosed', function(e, selectedDates) { var d = selectedDates[0]; if (d) { d = new Date(d); $('#start-date').dpSetEndDate(d.addDays(-1).asString()); } } ); }); But this does not seem to work. I would really appreciate any assistance with solving this!

  • using empty on inaccessible object with __isset and __get

    - by David
    <?php class Magic_Methods { protected $meta; public function __construct() { $this->meta = (object) array( 'test' => 1 ); } public function __isset($name) { echo "pass isset {$name} \n"; return isset($this->$name); } public function __get($name) { echo "pass get {$name} \n"; return $this->$name; } } $mm = new Magic_Methods(); $meta = empty($mm->meta->notExisting); var_dump($meta); echo "||\n"; $meta = empty($mm->meta); var_dump($meta); The snippet above does not work as expected for me. Why would the first empty() ommit the __isset? I get this: pass get meta bool(true) || pass isset meta pass get meta bool(false) I would expected identical results or another pass at the __isset, but not a direct call to __get. Or am I missing something here?

  • "Abstract static" method - how?

    - by polyglot
    There are already several SO questions on why there is not abstract static method/field as such, but I'm wondering about how one would go about implementing the following psuedo-code: class Animal { abstract static int getNumberOfLegs(); // not possible } class Chicken inherits Animal { static int getNumberOfLegs() { return 2; } class Dog inherits Animal { static int getNumberOfLegs() { return 4; } Here is the problem: Assuming that I want make sure that every class that inherits Animal to contain getNumberOfLegs() method (i.e. almost like an interface, except I do want the abstract class to implement several methods that are common to all child classes, hence pure interface does not work here). getNumberOfLegs() obviously should be a static method (assuming that in a perfect world we dont' have crippled chicken and dogs so getNumberOfLegs is not instance-dependent). Without an "abstract static" method/field, one can either leave the method out from Animal class, then there is the risk that some child class do not have that method. Or one can make getNumberOfLegs an instance method, but then one would have to instantiate a class to find out how many legs that animal has - even though it is not necessary. How do one usually go about implementing this situation?

  • Memory optimization while downloading

    - by lboregard
    hello all i have the following piece of code, that im looking forward to optimize, since i'm consuming gobs of memory this routine is heavily used first optimization would be to move the stringbuilder construction out of the download routine and make it a field of the class, then i would clear it inside the routine can you please suggest any other optimization or point me in the direction of some resources that could help me with this (web articles, books, etc). i'm thinking about replacing the stringbuilder by a fixed (much larger) size buffer ... or perhaps create a larger sized stringbuilder thanks in advance. StreamWriter _writer; StreamReader _reader; public string Download(string msgId) { _writer.WriteLine("BODY <" + msgId + ">"); string response = _reader.ReadLine(); if (!response.StartsWith("222")) return null; bool done = false; StringBuilder body = new StringBuilder(256* 1024); do { response = _reader.ReadLine(); if (OnProgress != null) OnProgress(response.Length); if (response == ".") { done = true; } else { if (response.StartsWith("..")) response = response.Remove(0, 1); body.Append(response); body.Append("\r\n"); } } while (!done); return body.ToString(); }

  • Repeated host lookups failing in urllib2

    - by reve_etrange
    I have code which issues many HTTP GET requests using Python's urllib2, in several threads, writing the responses into files (one per thread). During execution, it looks like many of the host lookups fail (causing a name or service unknown error, see appended error log for an example). Is this due to a flaky DNS service? Is it bad practice to rely on DNS caching, if the host name isn't changing? I.e. should a single lookup's result be passed into the urlopen? Exception in thread Thread-16: Traceback (most recent call last): File "/usr/lib/python2.6/threading.py", line 532, in __bootstrap_inner self.run() File "/home/da/local/bin/ThreadedDownloader.py", line 61, in run page = urllib2.urlopen(url) # get the page File "/usr/lib/python2.6/urllib2.py", line 126, in urlopen return _opener.open(url, data, timeout) File "/usr/lib/python2.6/urllib2.py", line 391, in open response = self._open(req, data) File "/usr/lib/python2.6/urllib2.py", line 409, in _open '_open', req) File "/usr/lib/python2.6/urllib2.py", line 369, in _call_chain result = func(*args) File "/usr/lib/python2.6/urllib2.py", line 1170, in http_open return self.do_open(httplib.HTTPConnection, req) File "/usr/lib/python2.6/urllib2.py", line 1145, in do_open raise URLError(err) URLError: <urlopen error [Errno -2] Name or service not known>

  • Issue with the Entity Manager and phpunit in Symfony 2

    I have an issue with my Entity Manager in phpunit. This is my test : public function testValidChangeEmail() { $client = self::createAuthClient('user','password'); $crawler = $client->request('GET', '/user/edit/30'); $crawler = $client->submit($crawler->selectButton('submit')->form(array( 'form[email]' => '[email protected]', ))); /* * With this em, this work perfectly * $em = $client->getContainer()->get('doctrine.orm.entity_manager'); */ $user = self::$em->getRepository('MyBundle:User')->findUser('[email protected]'); die(var_dump($user->getEmail())); } and this is my WebTestCase which extends original WebTestCase : class WebTestCase extends BaseWebTestCase { static protected $container; static protected $em; static protected function createClient(array $options = array(), array $server = array()) { $client = parent::createClient($options, $server); self::$em = $client->getContainer()->get('doctrine.orm.entity_manager'); self::$container = $client->getContainer(); return $client; } protected function createAuthClient($user, $pass) { return self::createClient(array(), array( 'PHP_AUTH_USER' => $user, 'PHP_AUTH_PW' => $pass, )); } As you can see, I replace the self::$em when I created my client. My issue : In my test, the die() give me the old email and not the new email ([email protected]) which has registered in the test. However in my database, I have the [email protected] correctly saved. When I retrieve my user in the database, I use sefl::$em. If I use the $em in comments, I retrieve the right new email. I don't understand why in my WebTestCase, I can access to the new Entity Manager...

  • Linq. Help me tune this!

    - by dtrick
    I have a linq query that is causing some timeout issues. Basically, I have a query that is returning the top 100 results from a table that has approximately 500,000 records. Here is the query: using (var dc = CreateContext()) { var accounts = string.IsNullOrEmpty(searchText) ? dc.Genealogy_Accounts .Where(a => a.Genealogy_AccountClass.Searchable) .OrderByDescending(a => a.ID) .Take(100) : dc.Genealogy_Accounts .Where(a => (a.Code.StartsWith(searchText) || a.Name.StartsWith(searchText)) && a.Genealogy_AccountClass.Searchable) .OrderBy(a => a.Code) .Take(100); return accounts.Select(a => } } Oddly enough it is the first linq query that is causing the timeout. I thought that by doing a 'Take' we wouldn't need to scan all 500k of records. However, that must be what is happening. I'm guessing that the join to find what is 'searchable' is causing the issue. I'm not able to denormalize the tables... so I'm wondering if there is a way to rewrite the linq query to get it to return quicker... or if I should just write this query as a Stored Procedure (and if so, what might it look like). Thanks.

  • Apache crashes, probably because of this piece of php code. Can you have a look?

    - by Munim
    I am working on the development of a web based application on codeigniter. I wrote this function to get the timezone data for any city or address. function gettimezone($address) { $_url = 'http://api.local.yahoo.com/MapsService/V1/geocode'; $_url .= sprintf('?appid=%s&location=%s',"phpclasses",rawurlencode($address)); $_result = false; if($_result = file_get_contents($_url)) { preg_match('!<Latitude>(.*)</Latitude><Longitude>(.*)</Longitude>!U', $_result, $_match); $lng = $_match[2]; $lat = $_match[1]; $url = "http://ws.geonames.org/timezone?lat={$lat}&lng={$lng}"; $timedata = file_get_contents($url); $sxml = simplexml_load_string($timedata); return $sxml->timezone; } else return false; } I am working on Windows 7 and xampp 1.7 (php 5.2.8). Is there any possible scenario where this piece of code would crash Apache? The application runs fine almost everytime, but I think running this piece of code when there is no internet connectivity or very poor internet connectivity (thereby no access to either of the webservices I have used) brings down the server. Something like this happened a few times and I think it was due to loss of internet connectivity but I am not sure what exactly is going on. [ By the way, feel free to use this piece of code. Makes 2 web service calls so don't use to too often in your application. Consider storing the results in a database.]

  • ASP.NET MVC Inserting object and related object into 2 tables

    - by ile
    I have two tables: Users and UserOwners. Table UserOwners contains list of users that certain user created (list of child-users) - or to be more precise, it contains UserOwnerID and UserID fields. So, now I want to create a new user... in Controller I have something like this: var userOwner = accountRepository.GetUser(User.Identity.Name); var userOwnerID = userOwner.UserID; UserReference userReference = new UserReference(); userReference.UserOwnerID = userOwnerID; if (ModelState.IsValid) { try { //accountRepository.Add(user); //accountRepository.Save(); return View(); } catch { return View(); } } What is the easiest way to add new user to a table Users and matching UserOwner to UserOwners table. Is it suppose to be something like this? public void Add(User user) { db.Users.InsertOnSubmit(user); db.UserReferences.InsertOnSubmit(user.UserReference); } ...or I will have to pass two objects and after adding user I must read it's ID and than assign it to userReference object and add that object to DB? If so, how to read ID of the last object added? Thanks, Ile

  • CodeModel help needed for right-hand singleton.getinstance() assignment.

    - by antarti
    I've been able to generate 99% of what I need with the CodeModel API, but I am stumped here... Using the various "directXX" methods does not add import statements to the generated code, and I can work without the "directXXX" type of methods except for one place in a generated class. Suppose I desire a generated method like: /** * Copies data from this Value-Obj instance, to the returned PERSON instance. * * @return PERSON * */ public PERSON mapVOToPERSON() throws MappingException { Mapper mapper = (com.blah.util.MapperSingleton.getMapperInstance()); return mapper.map(this, PERSON.class); } You can see the right hand of the Mapper assignment in parens. Emitting the entire package+class was the only way I could find to just declare "SomeSingleton.someMethod()" on the right hand side and have the generated code compile. Without the MapperSingleton being added to the object model, there is no import generated... Questions: 1) Is there a way to force an import to be generated? 2) How to declare an expression that gives me the right side of the Mapper assignment within the object model (so that an import of MapperSingleton gets generated. Any help appreciated...

  • How to negate a predicate function using operator ! in C++?

    - by Chan
    Hi, I want to erase all the elements that do not satisfy a criterion. For example: delete all the characters in a string that are not digit. My solution using boost::is_digit worked well. struct my_is_digit { bool operator()( char c ) const { return c >= '0' && c <= '9'; } }; int main() { string s( "1a2b3c4d" ); s.erase( remove_if( s.begin(), s.end(), !boost::is_digit() ), s.end() ); s.erase( remove_if( s.begin(), s.end(), !my_is_digit() ), s.end() ); cout << s << endl; return 0; } Then I tried my own version, the compiler complained :( error C2675: unary '!' : 'my_is_digit' does not define this operator or a conversion to a type acceptable to the predefined operator I could use not1() adapter, however I still think the operator ! is more meaningful in my current context. How could I implement such a ! like boost::is_digit() ? Any idea? Thanks, Chan Nguyen

  • How to create anonymous objects of type IQueryable using LINQ

    - by Soham Dasgupta
    Hi, I'm working in an ASP.NET MVC project where I have created a two LinqToSQL classes. I have also created a repository class for the models and I've implemented some methods like LIST, ADD, SAVE in that class which serves the controller with data. Now in one of the repository classes I have pulled some data with LINQ joins like this. private HerculesCompanyDataContext Company = new HerculesCompanyDataContext(); private HerculesMainDataContext MasterData = new HerculesMainDataContext(); public IQueryable TRFLIST() { var info = from trfTable in Company.TRFs join exusrTable in MasterData.ex_users on trfTable.P_ID equals exusrTable.EXUSER select new { trfTable.REQ_NO, trfTable.REQ_DATE, exusrTable.USER_NAME, exusrTable.USER_LNAME, trfTable.FROM_DT, trfTable.TO_DT, trfTable.DESTN, trfTable.TRAIN, trfTable.CAR, trfTable.AIRPLANE, trfTable.TAXI, trfTable.TPURPOSE, trfTable.STAT, trfTable.ROUTING }; return info; } Now when I call this method from my controller I'm unable to get a list. What I want to know is without creating a custom data model class how can I return an object of anonymous type like IQueryable. And because this does not belong to any one data model how can refer to this list in the view.

  • When should we use private variables and when should we use properties. Do Backing Fields should be

    - by Shantanu Gupta
    In most of the cases we usually creates a private variable and its corresponding public properties and uses them for performing our functionalities. Everyone has different approach like some people uses properties every where and some uses private variables within a same class as they are private and opens it to be used by external environment by using properties. Suppose I takes a scenario say insertion in a database. I creates some parameters that need to be initialized. I creates 10 private variables and their corresp public properties which are given as private string name; public string Name { get{return name;} set{name=value;} } and so on. In these cases mentioned above, what should be used internal variables or properties. And in those cases like public string Name { get{return name;} set{name=value>5?5:0;} //or any action can be done. this is just an eg. } In such cases what should be done.

  • Get context for search string in text in C#

    - by soundslike
    Given a string text which contains newline there is a search keyword which matches an item within the text. How do I implement the following in C#: searchIdx = search index (starting with 0, then 1, etc. for each successive call to GetSearchContext. Initially start with 0. contextsTxt = string data to search in searchTxt = keyword to search for in contextsTxt numLines = number of lines to return surrounding the searchTxt found (ie. 1 = the line the searchTxt is found on, 2 = the line the searchTxt is found on, 3 = the line above the searchTxt is found on, the line the searchTxt is found on, and the line below the searchTxt is found on) returns the "context" based on the parameters string GetSearchContext(int searchIdx, string contentsTxt, string searchTxt, int numLines); If there's a better function interface to accomplish this feel free to suggest that as well. I tried the following but doesn't seem to work properly all the time: private string GetSearchContext(string contentValue, string search, int numLines) { int searchIdx = contentValue.IndexOf(search); int startIdx = 0; int lastIdx = 0; while (startIdx != -1 && (startIdx = contentValue.IndexOf('\n', startIdx+1)) < searchIdx) { lastIdx = startIdx; } startIdx = lastIdx; if (startIdx < 0) startIdx = 0; int endIdx = searchIdx; int lineCnt = 0; while (endIdx != -1 && lineCnt++ < numLines) { endIdx = contentValue.IndexOf('\n', endIdx + 1); } if (endIdx == -1 || endIdx > contentValue.Length - 1) endIdx = contentValue.Length - 1; string lines = contentValue.Substring(startIdx, endIdx - startIdx + 1); if (lines[0] == '\n') lines = lines.Substring(1); if (lines[lines.Length - 1] == '\n') { lines = lines.Substring(0, lines.Length - 1); } if (lines[lines.Length - 1] == '\r') { lines = lines.Substring(0, lines.Length - 1); } return lines; }

  • INotifyPropertyChanged Setter Style

    - by Ivovic
    In order to reflect changes in your data to the UI you have to implement INotifyPropertyChanged, okay. If I look at examples, articles, tutorials etc most of the time the setters look like something in that manner: public string MyProperty { //get [...] set { if (_correspondingField == value) { return; } _correspondingField = value; OnPropertyChanged("MyProperty"); } } No problem so far, only raise the event if you have to, cool. But you could rewrite this code to this: public string MyProperty { //get [...] set { if (_correspondingField != value) { _correspondingField = value; OnPropertyChanged("MyProperty"); } } } It should do the same (?), you only have one place of return, it is less code, it is less boring code and it is more to the point ("only act if necessary" vs "if not necessary do nothing, the other way round act"). So if the second version has its pros compared to the first one, why I see this style rarely? I don't consider myself being smarter than those people that write frameworks, published articles etc, therefore the second version has to have drawbacks. Or is it wrong? Or do I think too much? Thanks in advance

  • Jquery animate negative top and back to 0 - starts messing up after 3rd click

    - by Daniel Takyi
    The site in question is this one: http://www.pickmixmagazine.com/wordpress/ When you click on one of the posts (any of the boxes) an iframe will slide down from the top with the content in it. Once the "Home" button in the top left hand corner of the iframe is clicked, the iframe slides back up. This works perfectly the first 2 times, on the 3rd click on of a post, the content will slide down, but when the home button is clicked, the content slides back up normally but once it has slid all the way up to the position it should be in, the iframe drops straight back down to where it was before the home button was clicked, I click it again and then it works. Here is the code I've used for both sliding up and sliding down functions: /* slide down function */ var $div = $('iframe.primary'); var height = $div.height(); var width = parseInt($div.width()); $div.css({ height : height }); $div.css('top', -($div.width())); $('.post').click(function () { $('iframe.primary').load(function(){ $div.animate({ top: 0 }, { duration: 1000 }); }) return false; }); /* slide Up function */ var elm = parent.document.getElementsByTagName('iframe')[0]; var jelm = $(elm);//convert to jQuery Element var htmlElm = jelm[0];//convert to HTML Element $('.homebtn').click(function(){ $(elm).animate({ top: -height }, { duration: 1000 }); return false; })

  • Array indexOf implentation for Internet Explorer

    - by Daemon
    There are plenty of solutions on how to get the indexOf implementation into the Array prototype so that it works under Internet Explorer, however I've stumbled upon an issue that doesn't seem to be addressed anywhere I've looked so far. Using the pretty well agreed upon implementation at MDC, I have the following code that's being problematic now: // indexOf support for IE (from MDC) if (!Array.prototype.indexOf) { Array.prototype.indexOf = function(elt /*, from*/) { var len = this.length >>> 0; var from = Number(arguments[1]) || 0; from = (from < 0) ? Math.ceil(from) : Math.floor(from); if (from < 0) from += len; for (; from < len; from++) { if (from in this && this[from] === elt) return from; } return -1; }; } var i = [1,2,3,4]; for (j in i) { alert(i[j]); } I am expecting to receive 4 alerts, each one containing one of the elements of the array. In Firefox and Chrome, that's exactly what I see, however in IE8 I get an additional alert containing the indexOf function code. What can be done to avoid this?

  • A Question about dereferencing pointer to incomplete type In C programming

    - by user552279
    Hi, can you explain this error for me? Blockquote /////////////////////////////// In my A.h file: struct TreeNode; struct TreeHead; typedef struct TreeNode * Node; typedef struct TreeHead * Head; /////////////////////////////// In my A.c file: struct TreeNode { char* theData; Node Left; Node Right; } ; struct TreeHead{ int counter; char type; Node Root; }; Head Initialisation() { Head treeHead; treeHead = malloc(sizeof (struct TreeHead)); treeHead-Root = malloc(sizeof (struct TreeNode)); return treeHead; } /////////////////////////////// In my Main.c file: Head head; Node tree; int choose =5; head = Initialisation(); (head-Root) = tree; //When compiling, this line has an error: error: dereferencing pointer to incomplete type Blockquote haed-Root will return a Node pointer, tree is also a Node pointer. So why error is dereferencing pointer to "incomplete" type?

  • Spring.net customer namespace parser

    - by ListenToRick
    I have a customer parser which looks like this: [NamespaceParser( Namespace = "http://mysite/schema/cache", SchemaLocationAssemblyHint = typeof(CacheNamespaceParser ), SchemaLocation = "/cache.xsd" ) ] public class CacheNamespaceParser : NamespaceParserSupport { public override void Init() { RegisterObjectDefinitionParser("cache", new CacheParser ()); } } public class CacheParser : AbstractSimpleObjectDefinitionParser { protected override Type GetObjectType(XmlElement element) { return typeof(CacheDefinition); } protected override void DoParse(XmlElement element, ObjectDefinitionBuilder builder) { } protected override bool ShouldGenerateIdAsFallback { get { return true; } } } in the web config i have the following configuration.... <spring> <parsers> <parser type="Spring.Data.Config.DatabaseNamespaceParser, Spring.Data"/> <parser type="App.Web.CacheNamespaceParser, WebApp" /> </parsers> When I run the project I get the following error: An error occurred creating the configuration section handler for spring/parsers: Invalid resource name. Name has to be in 'assembly:<assemblyName>/<namespace>/<resourceName>' format. I put a break point in the CacheNamespaceParser init method and it is called. If I remove from the web config all is well! Any ideas whats wrong
