  • Zend_Db_Select: regrouping conditions in where clause

    - by pvledoux
    Hi, I would like to do something like this: $select = $myTbl->select() ->from('download_log') ->joinLeft(...... etc........ ->joinLeft(...... etc........ ->joinLeft(...... etc........); //Filter all configured bots (Google, Yahoo, etc.) if(isset($this->_config->statistics->bots)){ $bots = explode(',',$this->_config->statistics->bots); foreach ($bots as $bot){ $select = $select->orWhere("user_agent NOT LIKE '%$bot%'"); } } $select = $select->where("download_log.download_log_ts BETWEEN '".$start_date." 00:00:00' AND '".$end_date." 23:59:59'"); But the outputed query is not correct because of the orWhere clauses are not grouped together in a unique AND clause. I would like to know if it is possible to regrouped those OR clauses in a pair of parentheres. My current alternative is the following: //Filter all configured bots (Google, Yahoo, etc.) if(isset($this->_config->statistics->bots)){ $bots = explode(',',$this->_config->statistics->bots); foreach ($bots as $bot){ $stmt .= "user_agent NOT LIKE '%$bot%' OR "; } $stmt = substr($stmt,0,strlen($stmt)-3); //remove the last OR $select = $select->where("($stmt)"); } Thanks!

  • Performing calculations by subsets of data in R

    - by Vivi
    I want to perform calculations for each company number in the column PERMNO of my data frame, the summary of which can be seen here: > summary(companydataRETS) PERMNO RET Min. :10000 Min. :-0.971698 1st Qu.:32716 1st Qu.:-0.011905 Median :61735 Median : 0.000000 Mean :56788 Mean : 0.000799 3rd Qu.:80280 3rd Qu.: 0.010989 Max. :93436 Max. :19.000000 My solution so far was to create a variable with all possible company numbers compns <- companydataRETS[!duplicated(companydataRETS[,"PERMNO"]),"PERMNO"] And then use a foreach loop using parallel computing which calls my function get.rho() which in turn perform the desired calculations rhos <- foreach (i=1:length(compns), .combine=rbind) %dopar% get.rho(subset(companydataRETS[,"RET"],companydataRETS$PERMNO == compns[i])) I tested it for a subset of my data and it all works. The problem is that I have 72 million observations, and even after leaving the computer working overnight, it still didn't finish. I am new in R, so I imagine my code structure can be improved upon and there is a better (quicker, less computationally intensive) way to perform this same task (perhaps using apply or with, both of which I don't understand). Any suggestions?

  • How to pass date parameters to Crystal Reports 2008 from an ASP.NET App?

    - by Unlimited071
    Hello all, I'm passing some parameters to a CR report programatically and it was working fine, but now that I have added a new date parameter to the report, for some reason, it is prompting me to enter that parameter on screen (the user isn't allowed to set that parameter is the system who must set it.), I haven't changed a thing other than adding the new date parameter, and all the other parameters behave normal, just the date parameter is prompted even thought I've already set a value for the parameter. This is the code I've got: private void ConfigureCrystalReports() { crystalReportViewer.ReportSource = GetReportPath(); crystalReportViewer.DataBind(); ConnectionInfo connectionInfo = GetConnectionInfo(); TableLogOnInfos tableLogOnInfos = crystalReportViewer.LogOnInfo; foreach (TableLogOnInfo tableLogOnInfo in tableLogOnInfos) { tableLogOnInfo.ConnectionInfo = connectionInfo; } ArrayList totOriValues = new ArrayList(); totOriValues.Add(date.ToString("MM/dd/yyyy HH:mm:ss")); ParameterFields parameterFields = crystalReportViewer.ParameterFieldInfo; SetCurrentValuesForParameterField(parameterFields, totOriValues, "DateParameter"); } private static void SetCurrentValuesForParameterField(ParameterFields parameterFields, ArrayList arrayList, string parameterName) { ParameterValues currentParameterValues = new ParameterValues(); foreach (object submittedValue in arrayList) { ParameterDiscreteValue parameterDiscreteValue = new ParameterDiscreteValue(); parameterDiscreteValue.Value = submittedValue.ToString(); currentParameterValues.Add(parameterDiscreteValue); } ParameterField parameterField = parameterFields[parameterName]; parameterField.CurrentValues = currentParameterValues; } Just for the sake of things: I have checked that the parameter is indeed a date and that it is well formed. CR prompts me to enter it in the format (mm/dd/yyyy hh:mm:ss) so I pass date in that exact format (In fact I've even tried hard coding a well-formed date and it still prompts me to enter the date). Am I doing something wrong?

  • dynamic JSF composite component styling/rendering

    - by Checkoff
    I've a little problem with a composite component. This component's implementation looks like: <composite:implementation> <h:outputStylesheet name="foo.css" library="bar"/> <div id="#{cc.clientId}"> <composite:insertChildren/> </div> </composite:implementation> It is included dynamically into a facelet page which include this component with JSTL core tags. The facelet page is similar to the following one. <h:panelGroup id="viewport" layout="block"> <c:if test="#{controller.object != null}"> <c:forEach items="#{controller.object.elements}" var="element"> <c:if test="#{element.type == 'type1'}"> <my:componentTypeOne id="#{element.id}"/> </c:if> <c:if test="#{element.type == 'type2'}"> <my:componentTypeTwo id="#{element.id}"/> </c:if> </c:forEach> </c:if> </h:panelGroup> So when I only render the viewport of the page the components are rendered but without the stylesheet defined within the composite component my:component. Is there any way to include the stylesheet on the fly without rendering the whole page? EDIT: extension of the example code..

  • Getting rid of nested using(...) statements

    - by Ghostrider
    Sometimes I need to use several disposable objects within a function. Most common case is having StreamReader and StreamWriter but sometimes it's even more than this. Nested using statements quickly add up and look ugly. To remedy this I've created a small class that collects IDisposable objects and disposes of them when it itself is disposed. public class MultiDispose : HashSet<IDisposable>, IDisposable { public MultiDispose(params IDisposable[] objectsToDispose) { foreach (IDisposable d in objectsToDispose) { this.Add(d); } } public T Add<T>(T obj) where T : IDisposable { base.Add(obj); return obj; } public void DisposeObject(IDisposable obj) { obj.Dispose(); base.Remove(obj); } #region IDisposable Members public void Dispose() { foreach (IDisposable d in this) { d.Dispose(); } } #endregion } So my code now looks like this: using (MultiDispose md = new MultiDispose()) { StreamReader rdr = md.Add(new StreamReader(args[0])); StreamWriter wrt = md.Add(new StreamWriter(args[1])); WhateverElseNeedsDisposing w = md.Add(new WhateverElseNeedsDisposing()); // code } Is there anything wrong with this approach that can cause problems down the road? I left the Remove function inherited from the HashSet on purpose so that the class would be more flexible. Surely misusing this function can lead to objects not being disposed of properly, but then there many other ways to shoot yourself in the foot without this class.

  • Is JPA persistence.xml classpath located?

    - by Vinnie
    Here's what I'm trying to do. I'm using JPA persistence in a web application, but I have a set of unit tests that I want to run outside of a container. I have my primary persistence.xml in the META_INF folder of my main app and it works great in the container (Glassfish). I placed a second persistence.xml in the META-INF folder of my test-classes directory. This contains a separate persistence unit that I want to use for test only. In eclipse, I placed this folder higher in the classpath than the default folder and it seems to work. Now when I run the maven build directly from the command line and it attempts to run the unit tests, the persistence.xml override is ignored. I can see the override in the META-INF folder of the maven generated test-classes directory and I expected the maven tests to use this file, but it isn't. My Spring test configuration overrides, achieved in a similar fashion are working. I'm confused at to whether the persistence.xml is located through the classpath. If it were, my override should work like the spring override since the maven surefire plugin explains "[The test class directory] will be included at the beginning the test classpath". Did I wrongly anticipate how the persistence.xml file is located? I could (and have) create a second persistence unit in the production persistence.xml file, but it feels dirty to place test configuration into this production file. Any other ideas on how to achieve my goal is welcome.

  • Game architecture: modeling different steps/types of UI

    - by Sander
    I have not done any large game development projects, only messed around with little toy projects. However, I never found an intuitive answer to a specific design question. Namely, how are different types/states of UI modeled in games? E.g. how is a menu represented? How is it different from a "game world" state (let's use an FPS as an example). How is an overlaid menu on top of a "game world" modeled? Let's imagine the main loop of a game. Where do the game states come into play? It it a simple case-by-case approach? if (menu.IsEnabled) menu.Process(elapsedTime); if (world.IsEnabled) world.Process(elapsedTime); if (menu.IsVisible) menu.Draw(); if (world.IsVisible) world.Draw(); Or are menu and world represented somewhere in a different logic layer and not represented at this level? (E.g. a menu is just another high-level entity like e.g. player input or enemy manager, equal to all others) foreach (var entity in game.HighLevelEntities) entity.Process(elapsedTime); foreach (var entity in game.HighLevelEntities) entity.Draw(elapsedTime); Are there well-known design patterns for this? Come to think of it, I don't know any game-specific design patterns - I assume there are others, as well? Please tell me about them.

  • Is it bad use "display: table;" to organise a layout into 2 columns?

    - by Colen
    Hello, I am trying to make a 2 column layout, apparently the bane of CSS. I know you shouldn't use tables for layout, but I've settled on this CSS. Note the use of display: table etc. div.container { width: 600px; height: 300px; margin: auto; display: table; table-layout: fixed; } ul { white-space: nowrap; overflow: hidden; display: table-cell; width: 40%; } div.inner { display: table-cell; width: auto; } With this layout: <div class="container"> <ul> <li>First</li> <li>Second</li> <li>Third</li> </ul> <div class="inner"> <p>Hello world</p> </div> </div> This seems to work admirably. However, I can't help wondering - am I obeying the letter of the "don't use tables" rule, but not the spirit? I think it's ok, since there's no positioning markup in the HTML code, but I'm just not sure about the "right" way to do it. I can't use css float, because I want the columns to expand and contract with the available space. Please, stack overflow, help me resolve my existential sense of dread at these pseudo-tables.

  • Serializing QGraphicsScene contents

    - by Rob
    I am using the Qt QGraphicsScene class, adding pre-defined items such as QGraphicsRectItem, QGraphicsLineItem, etc. and I want to serialize the scene contents to disk. However, the base QGraphicsItem class (that the other items I use derive from) doesn't support serialization so I need to roll my own code. The problem is that all access to these objects is via a base QGraphicsItem pointer, so the serialization code I have is horrible: QGraphicsScene* scene = new QGraphicsScene; scene->addRect(QRectF(0, 0, 100, 100)); scene->addLine(QLineF(0, 0, 100, 100)); ... QList<QGraphicsItem*> list = scene->items(); foreach (QGraphicsItem* item, items) { if (item->type() == QGraphicsRectItem::Type) { QGraphicsRectItem* rect = qgraphicsitem_cast<QGraphicsRectItem*>(item); // Access QGraphicsRectItem members here } else if (item->type() == QGraphicsLineItem::Type) { QGraphicsLineItem* line = qgraphicsitem_cast<QGraphicsLineItem*>(item); // Access QGraphicsLineItem members here } ... } This is not good code IMHO. So, instead I could create an ABC class like this: class Item { public: virtual void serialize(QDataStream& strm, int version) = 0; }; class Rect : public QGraphicsRectItem, public Item { public: void serialize(QDataStream& strm, int version) { // Serialize this object } ... }; I can then add Rect objects using QGraphicsScene::addItem(new Rect(,,,)); But this doesn't really help me as the following will crash: QList<QGraphicsItem*> list = scene->items(); foreach (QGraphicsItem* item, items) { Item* myitem = reinterpret_class<Item*>(item); myitem->serialize(...) // FAIL } Any way I can make this work?

  • LINQ to Sql: Insert instead of Update

    - by Christina Mayers
    I am stuck with this problems for a long time now. Everything I try to do is insert a row in my DB if it's new information - if not update the existing one. I've updated many entities in my life before - but what's wrong with this code is beyond me (probably something pretty basic) I guess I can't see the wood for the trees... private Models.databaseDataContext db = new Models.databaseDataContext(); internal void StoreInformations(IEnumerable<EntityType> iEnumerable) { foreach (EntityType item in iEnumerable) { EntityType type = db.EntityType.Where(t => t.Room == item.Room).FirstOrDefault(); if (type == null) { db.EntityType.InsertOnSubmit(item); } else { type.Date = item.Date; type.LastUpdate = DateTime.Now(); type.End = item.End; } } } internal void Save() { db.SubmitChanges(); } Edit: just checked the ChangeSet, there are no updates only inserts. For now I've settled with foreach (EntityType item in iEnumerable) { EntityType type = db.EntityType.Where(t => t.Room == item.Room).FirstOrDefault(); if (type != null) { db.Exams.DeleteOnSubmit(type); } db.EntityType.InsertOnSubmit(item); } but I'd love to do updates and lose these unnecessary delete statements.

  • Adding jQuery event handler to expand div when a link is clicked

    - by hollyb
    I'm using a bit of jQuery to expand/hide some divs. I need to add an event handler so that when a link is clicked, it opens a corrisponding div. Each toggled div will have a unique class assigned to it. I am looking for some advice about how to build the event handler. The jQuery $(document).ready(function(){ $(".toggle_container:not(:first)").hide(); $(".toggle_container:first").show(); $("h6.trigger:first").addClass("active"); $("h6.trigger").click(function(){ $(this).toggleClass("active"); $(this).next(".toggle_container").slideToggle(300); }); The css: // uses a background image with an on (+) and off (-) state stacked on top of each other h6.trigger { background: url(buttonBG.gif) no-repeat;height: 46px;line-height: 46px;width: 300px;font-size: 2em;font-weight: normal;} h6.trigger a {color: #fff;text-decoration: none; display: block;} h6.active {background-position: left bottom;} .toggle_container { overflow: hidden; } .toggle_container .block {padding: 20px;} The html has a list of links, such as: <a href="#">One</a> <a href="#">Two</a> and the coorisponding divs to open: <h6 class="trigger">Container one</h6> <div class="toggle_container"> div one </div> <h6 class="trigger">Container two</h6> <div class="toggle_container Open"> div one </div> As I mentioned, I will be assigning a unique class to facilitate this. Any advice? Thanks! To clarify, i'm looking for some advice to build an event handler to toggle open a specific div when a link is clicked from a different part of the page, from a nav for instance.

  • wrapping user controls in a transaction

    - by Hans Gruber
    I'm working on heavily dynamic and configurable CMS system. Therefore, many pages are composed of a dynamically loaded set of user controls. To enable loose coupling between containers (pages) and children (user controls), all user controls are responsible for their own persistence. Each User Control is wired up to its data/service layer dependencies via IoC. They also implement an IPersistable interface, which allows the container .aspx page to issue a Save command to its children without knowledge of the number or exact nature of these user controls. Note: what follows is only pseudo-code: public class MyUserControl : IPersistable, IValidatable { public void Save() { throw new NotImplementedException(); } public bool IsValid() { throw new NotImplementedException(); } } public partial class MyPage { public void btnSave_Click(object sender, EventArgs e) { foreach (IValidatable control in Controls) { if (!control.IsValid) { throw new Exception("error"); } } foreach (IPersistable control in Controls) { if (!control.Save) { throw new Exception("error"); } } } } I'm thinking of using declarative transactions from the System.EnterpriseService namespace to wrap the btnSave_Click in a transaction in case of an exception, but I'm not sure how this might be achieved or any pitfalls to such an approach.

  • ASP.NET dropdownlist callback doesn't work inside div

    - by Wayne Werner
    This seems super weird to me. I have a callback handler done in VB which works fine with this code: <!-- Div Outside Form --> <div class="container"> <form id="querydata" runat="server"> <asp:DropDownList runat="server" ID="myddl" AutoPostBack="true" OnSelectedIndexChanged="myddlhandler"> <asp:ListItem>Hello</asp:ListItem> <asp:ListItem>Goodbye</asp:ListItem> </asp:DropDownList> <asp:Label runat="server" ID="label1"></asp:Label> </form> </div> <!-- Yep, they're matching --> I can change the value and everything is A-OK, but if I change the code to this (div inside form): <form id="querydata" runat="server"> <!-- Div inside form doesn't work :( --> <div class="container"> <asp:DropDownList runat="server" ID="myddl" AutoPostBack="true" OnSelectedIndexChanged="myddlhandler"> <asp:ListItem>Hello</asp:ListItem> <asp:ListItem>Goodbye</asp:ListItem> </asp:DropDownList> <asp:Label runat="server" ID="label1"></asp:Label> </div> </form> It the postback no longer works. Is how asp is supposed to work? Or is it some magic error that only works for me? And most importantly, if asp is not supposed to work this way, how should I be doing this? Thanks!

  • Getting table schema from a query

    - by Appu
    As per MSDN, SqlDataReader.GetSchemaTable returns column metadata for the query executed. I am wondering is there a similar method that will give table metadata for the given query? I mean what tables are involved and what aliases it has got. In my application, I get the query and I need to append the where clause programically. Using GetSchemaTable(), I can get the column metadata and the table it belongs to. But even though table has aliases, it still return the real table name. Is there a way to get the aliase name for that table? Following code shows getting the column metadata. const string connectionString = "your_connection_string"; string sql = "select c.id as s,c.firstname from contact as c"; using(SqlConnection connection = new SqlConnection(connectionString)) using(SqlCommand command = new SqlCommand(sql, connection)) { connection.Open(); SqlDataReader reader = command.ExecuteReader(CommandBehavior.KeyInfo); DataTable schema = reader.GetSchemaTable(); foreach (DataRow row in schema.Rows) { foreach (DataColumn column in schema.Columns) { Console.WriteLine(column.ColumnName + " = " + row[column]); } Console.WriteLine("----------------------------------------"); } Console.Read(); } This will give me details of columns correctly. But when I see BaseTableName for column Id, it is giving contact rather than the alias name c. Is there any way to get the table schema and aliases from a query like the above? Any help would be great!

  • Messages not forwarded to error queue when exception is thrown in handler (it works on my machine)

    - by darthjit
    e are using NServicebus 4.0.5 with sql server(sql server 2012) as transport. When the handler throws an exception, NSB does not retry or move the message to the error queue. Successful messages make it to the audit queue but the failed/errored ones don't! . Interestingly, all this works on our local machines(windows 7 ,sql server localdb) but not on windows server 2012 (sql server 2012). Here is the config info on the subscriber: <add name="NServiceBus/Transport" connectionString="Data Source=xxx;Initial Catalog=NServiceBus;Integrated Security=SSPI;Enlist=false;" /> <add name="NServiceBus/Persistence" connectionString="Data Source=xxx;Initial Catalog=NServiceBus;Integrated Security=SSPI;Enlist=false;" /> <MessageForwardingInCaseOfFaultConfig ErrorQueue="error" /> <UnicastBusConfig ForwardReceivedMessagesTo="audit"> <MessageEndpointMappings> <add Assembly="Services.Section.Messages" Endpoint= "Services.ACL.Worker" /> </MessageEndpointMappings> </UnicastBusConfig> And in code it is configured as follows: public class EndpointConfig : IConfigureThisEndpoint, AsA_Server, IWantCustomInitialization { public void Init() { IContainer container = ContainerInstanceProvider. GetContainerInstance(); Configure .Transactions.Enable(); Configure.With() .AutofacBuilder(container) .UseTransport<SqlServer>() .Log4Net() //.Serialization.Json() .UseNHibernateSubscriptionPersister() .UseNHibernateTimeoutPersister() .MessageForwardingInCaseOfFault() .RijndaelEncryptionService() .DefiningCommandsAs(type => type.Namespace != null &&type .Namespace.EndsWith("Commands")) .DefiningEventsAs(type => type.Namespace != null &&type .Namespace.EndsWith("Events")) .UnicastBus(); } } Any ideas on how to fix this? here is the log info (there is a lot there, search for error to see the relevant parts) https://gist.github.com/ranji/7378249

  • Prevent box shadow from showing on a specific side

    - by kaile
    Is there any way to create a css box-shadow in which regardless of the blur value, the shadow only appears on the desired sides? For example if I want to create a div with shadows on left and right sides and no shadow on the top or bottom. The div is not absolutely positioned and its height is determined by the content. -- Edit -- @ricebowl: I appreciate your answer. Maybe you can help with creating a complete solution to fix the problems stated in my reply to your solution... My page setup is as follows: <div id="container"> <div id="header"></div> <div id="content"></div> <div id="clearfooter"></div> </div> <div id="footer"></div> And CSS like this: #container {width:960px; min-height:100%; margin:0px auto -32px auto; position:relative; padding:0px; background-color:#e6e6e6; -moz-box-shadow: -3px 0px 5px rgba(0,0,0,.8), 3px 0px 5px rgba(0,0,0,.8);} #header {height:106px; position:relative;} #content {position:relative;} #clearFooter {height:32px; clear:both; display:block; padding:0px; margin:0px;} #footer {height:32px; padding:0px; position:relative; width:960px; margin:0px auto 0px auto;}

  • How to receive Email in JEE application

    - by Hank
    Obviously it's not so difficult to send out emails from a JEE application via JavaMail. What I am interested in is the best pattern to receive emails (notification bounces, mostly)? I am not interested in IMAP/POP3-based approaches (polling the inbox) - my application shall react to inbound emails. One approach I could think of would be Keep existing MTA (postfix on linux in my case) - ops team already knows how to configure / operate it For every mail that arrives, spawn a Java app that receives the data and sends it off via JMS. I could do this via an entry in /etc/aliases like myuser: "|/path/to/javahelper" with javahelper calling the Java app, passing STDIN along. MDB (part of JEE application) receives JMS message, parses it, detects bounce message and acts accordingly. Another approach could be Open a listening network socket on port 25 on the JEE application container. Associate a SessionBean with the socket. Bean is part of JEE application and can parse/detect bounces/handle the messages directly. Keep existing MTA as inbound relay, do all its security/spam filtering, but forward emails to myuser (that pass the filter) to the JEE application container, port 25. The first approach I have done before (albeit in a different language/setup). From a performance and (perceived) cleanliness point of view, I think the second approach is better, but it would require me to provide a proper SMTP transport implementation. Also, I don't know if it's at all possible to connect a network socket with a bean... What is your recommendation? Do you have details about the second approach?

  • Insert array to mysql database php

    - by ganjan
    Hi. I want to add an array to my db. I have set up a function that checks if a value in the db (ex. health and money) has changed. If the value is diffrent from the original I add the new value to the $db array. Like this $db['money'] = $money_input + $money_db;. function modify_user_info($conn, $money_input, $health_input){ (...) if ($result = $conn->query($query)) { while ($user = $result->fetch_assoc()) { $money_db = $user["money"]; $health_db = $user["health"]; } $result->close(); //lag array til db med kolonnene som skal fylles ut som keys i array if ($user["money"] != $money_input){ $db['money'] = $money_input + $money_db; //0 - 20 if (!preg_match("/^[[0-9]{0,20}$/i", $db['money'])){ echo "error"; return false; } } if ($user["health"] != $health_input){ $db['health'] = $health_input + $health_db; //0 - 4 if (!preg_match("/^[[0-9]{0,4}$/i", $db['health'])){ echo "error"; return false; } if (($db['health'] < 1) or ($db['health'] > 1000)) { echo "error"; return false; } } The keys in $db represent colums in my database. Now I want to make a function that takes the keys in the array $db and insert them in the db. Something like this ? $query = "INSERT INTO `main_log` ( `id` , "; foreach(range(0, x) as $num) { $query .= array_key.", "; } $query = substr($query, 0, -3); $query .= " VALUES ('', "; foreach(range(0, x) as $num) { $query .= array_value.", "; } $query = substr($query, 0, -3); $query .= ")";

  • array_splice() - Numerical Offsets of Associative Arrays

    I'm trying to do something but I can't find any solution, I'm also having some trouble putting it into works so here is a sample code, maybe it'll be enough to demonstrate what I'm aiming for: $input = array ( 'who' => 'me', 'what' => 'car', 'more' => 'car', 'when' => 'today', ); Now, I want to use array_splice() to remove (and return) one element from the array: $spliced = key(array_splice($input, 2, 1)); // I'm only interested in the key... The above will remove and return 1 element (third argument) from $input (first argument), at offset 2 (second argument), so $spliced will hold the value more. I'll be iterating over $input with a foreach loop, I know the key to be spliced but the problem is I don't know its numerical offset and since array_splice only accepts integers I don't know what to do. A very dull example: $result = array(); foreach ($input as $key => $value) { if ($key == 'more') { // Remove the index "more" from $input and add it to $result. $result[] = key(array_splice($input, 2 /* How do I know its 2? */, 1)); } } I first though of using array_search() but it's pointless since it'll return the associative index.... How do I determine the numerical offset of a associative index?

  • nhibernate : Repository Session Management

    - by frosty
    At the moment my repository has 2 constructors. When i call these from my mvc website i am alway calling first constructor and thus opening a new session. Should i been passing in the session. How should i be doing this. public CompanyRepository() { _session = NHibernateHelper.OpenSession(); } public CompanyRepository(ISession session) { _session = session; } public class NHibernateHelper { private static ISessionFactory _sessionFactory; private static ISessionFactory SessionFactory { get { if (_sessionFactory == null) { var configuration = new Configuration(); configuration.Configure(); configuration.AddAssembly(typeof(UserProfile).Assembly); configuration.SetProperty(NHibernate.Cfg.Environment.ConnectionStringName, System.Environment.MachineName); _sessionFactory = configuration.BuildSessionFactory(); } return _sessionFactory; } } public static ISession OpenSession() { return SessionFactory.OpenSession(); } } I'm using the Ninject IOC container ( very new to me ). I have the following container. How would i bind the ISession to the CompanyRepository. private class EStoreDependencies : NinjectModule { public override void Load() { Bind<ICompanyRepository>().To<CompanyRepository>(); Bind<IUserProfileRepository>().To<UserProfileRepository>(); Bind<IAddressRepository>().To<AddressRepository>(); Bind<IRolesService>().To<AspNetRoleProviderWrapper>(); Bind<IUserService>().To<AspNetMembershipProviderWrapper>(); Bind<ICurrentUserSerivce>().To<DefaultCurrentUserSerivce>(); Bind<IPasswordService>().To<AspNetMembershipProviderWrapper>(); Bind<IStatusResponseRepository>().To<StatusResponseRepository>(); Bind<ICategoryRepository>().To<CategoryRepository>(); Bind<IProductRepository>().To<ProductRepository>(); } }

  • ControlCollection extension method optimazation

    - by Johan Leino
    Hi, got question regarding an extension method that I have written that looks like this: public static IEnumerable<T> FindControlsOfType<T>(this ControlCollection instance) where T : class { T control; foreach (Control ctrl in instance) { if ((control = ctrl as T) != null) { yield return control; } foreach (T child in FindControlsOfType<T>(ctrl.Controls)) { yield return child; } } } public static IEnumerable<T> FindControlsOfType<T>(this ControlCollection instance, Func<T, bool> match) where T : class { return FindControlsOfType<T>(instance).Where(match); } The idea here is to find all controls that match a specifc criteria (hence the Func<..) in the controls collection. My question is: Does the second method (that has the Func) first call the first method to find all the controls of type T and then performs the where condition or does the "runtime" optimize the call to perform the where condition on the "whole" enumeration (if you get what I mean). secondly, are there any other optimizations that I can do to the code to perform better. An example can look like this: var checkbox = this.Controls.FindControlsOfType<MyCustomCheckBox>( ctrl => ctrl.CustomProperty == "Test" ) .FirstOrDefault();

  • d2: assigning ranges/iterators to array slices

    - by modchan
    Consider following code: enum size = 16; double[size] arr1 = [...]; double[size] arr2 = [...]; process = (double x) { return (x + 1); }; arr2[] = map!(process)(arr1[]); // here I have trouble converting results of map back to my plain array. Problem applies not only to map, but also to take, repeat and all those fine tools from std.algorithm and std.range that operate on ranges. On this assignment, I get Error: cannot implicitly convert expression (map(arr1[])) of type Result to double[]. How can I evaluate range to array without using uint i = 0; foreach (x; map!(process)(arr1[])) { arr2[i] = x; i++; } ? Additionally, can someone please explain, why I must call map!(process)(arr1[]) instead of map!(process)(arr1) with static arrays? Shouldn't static arrays be compatible with dynamic for means of iteration, or I don't get something? Also, it seems that straightforward enumeration syntax foreach (index, item; sequence) does not work for ranges - are there workarounds? I guess the reason is the same as why ranges cannot be assigned to array slices.

  • Events still not showing up despite the many tries...sigh

    - by sheng88
    I have tried the recommendation from this forum and through the many google searches...but i still can't get the events to show up on my calendar via jsp....i tried with php and it worked...sigh...i wonder where is the error....sigh.... The processRequest method is fine but when it dispatches to the JSP page...nothing appears from the browser.... protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { String email=request.getParameter("email"); try { ArrayList<CalendarEvt> calc=CalendarDAO.retrieveEvent(email); for (CalendarEvt calendarEvt : calc) { System.out.println(calendarEvt.getEventId()); } request.setAttribute("calendar", calc); request.getRequestDispatcher("calendar.jsp").forward(request, response); } catch (Exception e) { } } Here is the JSP section that's giving me headaches...(Without the loop...the Google link does appear...)...I have tried putting quotations and leaving them out....still no luck: <%--Load user's calendar--%> <script type='text/javascript'> $(document).ready(function() { var date = new Date(); var d = date.getDate(); var m = date.getMonth(); var y = date.getFullYear(); $('#calendar').fullCalendar({ editable: false, events: [ <c:forEach items="calendar" var="calc"> { title: '${calc.eventName}', start: ${calc.eventStart} }, </c:forEach> { title: 'Click for Google', start: new Date(y, m, 1), end: new Date(y, m, 1), url: 'http://google.com/' } ]//end of events }); }); </script> <%--Load user's calendar--%> ...any kind of help would be greatly appreciated...thx!!
