  • Issues loading SWF with External SWF Files - using SWFObject and ExternalInterface

    - by wdense51
    I'm having issues with loading a SWF that references external SWF files... The main SWF loads fine if the HTML file is in the same folder as all the SWFs using the following code: <script type="text/javascript" src="../js/swfobject.js"></script> <script type="text/javascript"> var flashvars = {}; var params = { allowScriptAccess: "always" }; params.quality = "high"; params.wmode = "transparent"; var attributes = {id:"IDofSWF", name:"IDofSWF"}; swfobject.embedSWF("event_so_js.swf", "flashContent", "700", "400", "7.0.0", false, flashvars, params, attributes);</script> </head> <body> <div id="flashContent"> <object data="event_so_js.swf" name="IDofSWF" id="IDofSWF" type="application/x-shockwave-flash" width="700" height="400"></object></div> But as soon as I move the HTML file out of that folder to the root folder and update the links, it doesn't load correctly - it seems that it's having trouble with the external SWF files. I did have it successfully load one of the external SWF files directly, but it's having trouble with the main SWF. All of the SWF files are in the same folder, so I don't know why it's having issues. Here's the code for the HTML file when it's in the root folder: <script type="text/javascript" src="js/swfobject.js"></script> <script type="text/javascript"> var flashvars = {}; var params = { allowScriptAccess: "always" }; params.quality = "high"; params.wmode = "transparent"; var attributes = {id:"IDofSWF", name:"IDofSWF"}; swfobject.embedSWF("folio/event_so_js.swf", "flashContent", "700", "400", "9.0.0", false, flashvars, params, attributes);</script> </head> <body> <div id="flashContent"> <object data="folio/event_so_js.swf" name="IDofSWF" id="IDofSWF" type="application/x-shockwave-flash" width="700" height="400"></object></div> There is also a link on the page that calls a function in the actionscript using ExternalInterface, so it could be that causing the issues. The code for the link is: <a href="#" onclick="document.getElementById('IDofSWF').clicky()"> Any help would be awesome, because it's really confusing me.

  • How to use second level cache for lazy loaded collections in Hibernate?

    - by Chandru
    Let's say I have two entities, Employee and Skill. Every employee has a set of skills. Now when I load the skills lazily through the Employee instances the cache is not used for skills in different instances of Employee. Let's Consider the following data set. Employee - 1 : Java, PHP Employee - 2 : Java, PHP When I load Employee - 2 after Employee - 1, I do not want hibernate to hit the database to get the skills and instead use the Skill instances already available in cache. Is this possible? If so how? Hibernate Configuration <session-factory> <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property> <property name="hibernate.connection.password">pass</property> <property name="hibernate.connection.url">jdbc:mysql://localhost/cache</property> <property name="hibernate.connection.username">root</property> <property name="hibernate.dialect">org.hibernate.dialect.MySQLInnoDBDialect</property> <property name="hibernate.cache.use_second_level_cache">true</property> <property name="hibernate.cache.use_query_cache">true</property> <property name="hibernate.cache.provider_class">net.sf.ehcache.hibernate.EhCacheProvider</property> <property name="hibernate.hbm2ddl.auto">update</property> <property name="hibernate.show_sql">true</property> <mapping class="org.cache.models.Employee" /> <mapping class="org.cache.models.Skill" /> </session-factory> The Entities with imports, getters and setters Removed @Entity @Table(name = "employee") @Cache(usage = CacheConcurrencyStrategy.READ_WRITE) public class Employee { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private int id; private String name; public Employee() { } @ManyToMany @JoinTable(name = "employee_skills", joinColumns = @JoinColumn(name = "employee_id"), inverseJoinColumns = @JoinColumn(name = "skill_id")) @Cache(usage = CacheConcurrencyStrategy.READ_WRITE) private List<Skill> skills; } @Entity @Table(name = "skill") @Cache(usage = CacheConcurrencyStrategy.READ_WRITE) public class Skill { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private int id; private String name; } SQL for Loading the Second Employee and his Skills Hibernate: select employee0_.id as id0_0_, employee0_.name as name0_0_ from employee employee0_ where employee0_.id=? Hibernate: select skills0_.employee_id as employee1_1_, skills0_.skill_id as skill2_1_, skill1_.id as id1_0_, skill1_.name as name1_0_ from employee_skills skills0_ left outer join skill skill1_ on skills0_.skill_id=skill1_.id where skills0_.employee_id=? In that I specifically want to avoid the second query as the first one is unavoidable anyway.

  • OneToOne JPA / Hibernate eager loading cause N+1 select

    - by Alexandre Lavoie
    I created a method to have multilingual text on different objects without creating field for each languages or tables for each objects types. Now the only problem I've got is N+1 select queries when doing a simple loading. Tables schema : CREATE TABLE `testentities` ( `keyTestEntity` int(11) NOT NULL, `keyMultilingualText` int(11) NOT NULL, PRIMARY KEY (`keyTestEntity`) ) ENGINE=MyISAM AUTO_INCREMENT=0 DEFAULT CHARSET=utf8; CREATE TABLE `common_multilingualtexts` ( `keyMultilingualText` int(11) NOT NULL auto_increment, PRIMARY KEY (`keyMultilingualText`) ) ENGINE=MyISAM AUTO_INCREMENT=0 DEFAULT CHARSET=utf8; CREATE TABLE `common_multilingualtexts_values` ( `languageCode` varchar(5) NOT NULL, `keyMultilingualText` int(11) NOT NULL, `value` text, PRIMARY KEY (`languageCode`,`keyMultilingualText`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8; MultilingualText.java @Entity @Table(name = "common_multilingualtexts") public class MultilingualText implements Serializable { private Integer m_iKeyMultilingualText; private Map<String, String> m_lValues = new HashMap<String, String>(); public void setKeyMultilingualText(Integer p_iKeyMultilingualText) { m_iKeyMultilingualText = p_iKeyMultilingualText; } @Id @GeneratedValue @Column(name = "keyMultilingualText") public Integer getKeyMultilingualText() { return m_iKeyMultilingualText; } public void setValues(Map<String, String> p_lValues) { m_lValues = p_lValues; } @ElementCollection(fetch = FetchType.EAGER) @CollectionTable(name = "common_multilingualtexts_values", joinColumns = @JoinColumn(name = "keyMultilingualText")) @MapKeyColumn(name = "languageCode") @Column(name = "value") public Map<String, String> getValues() { return m_lValues; } public void put(String p_sLanguageCode, String p_sValue) { m_lValues.put(p_sLanguageCode,p_sValue); } public String get(String p_sLanguageCode) { if(m_lValues.containsKey(p_sLanguageCode)) { return m_lValues.get(p_sLanguageCode); } return null; } } And it is used like this on a object (having a foreign key to the multilingual text) : @Entity @Table(name = "testentities") public class TestEntity implements Serializable { private Integer m_iKeyEntity; private MultilingualText m_oText; public void setKeyEntity(Integer p_iKeyEntity) { m_iKeyEntity = p_iKeyEntity; } @Id @GeneratedValue @Column(name = "keyEntity") public Integer getKeyEntity() { return m_iKeyEntity; } public void setText(MultilingualText p_oText) { m_oText = p_oText; } @OneToOne(cascade = CascadeType.ALL) @JoinColumn(name = "keyText") public MultilingualText getText() { return m_oText; } } Now, when doing a simple HQL query : from TestEntity, I get a query selecting TestEntity's and one query for each MultilingualText that need to be loaded on each TestEntity. I've searched a lot and found absolutely no solutions. I have tested : @Fetch(FetchType.JOIN) optional = false @ManyToOne instead of @OneToOne Now I am out of idea!

    I am displaying pdf on my page like this <object data="/Customer/GetPricedMaterialPDF?projID=<%= ViewData["ProjectID"]%>" type="application/pdf" width="960" height="900" style="margin-top: -33px;"> <p> It appears you don't have a PDF plugin for this browser. No biggie... you can <a href="/Customer/GetPricedMaterialPDF?projID=<%= ViewData["ProjectID"]%>">click here to download the PDF file. </a> </p> </object> and Controller function are public FileStreamResult GetPricedMaterialPDF(string projID) { System.IO.Stream fileStream = GeneratePDF(projID); HttpContext.Response.AddHeader("content-disposition", "attachment; filename=form.pdf"); return new FileStreamResult(fileStream, "application/pdf"); } private System.IO.Stream GeneratePDF(string projID) { //create your pdf and put it into the stream... pdf variable below //comes from a class I use to write content to PDF files System.IO.MemoryStream ms = new System.IO.MemoryStream(); Project proj = GetProject(projID); List<File> ff = proj.GetFiles(Project_Thin.Folders.IntegrationFiles, true); string fileName = string.Empty; if (ff != null && ff.Count > 0 && ff.Where(p => p.AccessToUserID == CurrentCustomer.CustomerID).Count() > 0) { ff = ff.Where(p => p.AccessToUserID == CurrentCustomer.CustomerID).ToList(); foreach (var item in ff) { fileName = item.FileName; } byte[] bArr = new byte[] { }; bArr = GetJDLFile(fileName); ms.Write(bArr, 0, bArr.Length); ms.Position = 0; } return ms; } Now my problem is function on controller taking 10 to 20 second to process pdf, data="/Customer/GetPricedMaterialPDF?projID=<%= ViewData["ProjectID"]%>" at that time my page shows blank, which i don't want. i want to show loading image at that time.

  • Objects not loading on second request in Restkit

    - by Holger Edward Wardlow Sindbæk
    I'm sending off 2 requests simultaneously with Restkit and I receive a response back from both of them, but only one of the requests receives any objects. If I send them off one by one, then my objectloader receives all objects.

  • CellTable + AsyncListViewAdapter<T>, stuck at 'loading' when paging

    - by Jaroslav Záruba
    Hi I'm trying to make CellTable, AsyncListViewAdapter<T> and SimplePager<T> working together. I managed to display my data, but whenever I click either "go to start" or "go to end" button I get that 'loading' indicator which stays there till the end of days. ( AsyncListViewAdapter<T>.onRangeChanged doesn't even get called this time.) As I have only single row in my data those two buttons should be (and appear to be) disabled. I went through the code-snippets in this thread, but I can't see nothing suspicions in what I've been doing. Is there some obvious answer to a rookie mistake? I shrinked my variable names, hopefully it won't wrap too much. protected class MyAsyncAdapter extends AsyncListViewAdapter<DTO> { @Override protected void onRangeChanged(ListView<DTO> v) { // doesn't get called on go2start/go2end :( Range r = v.getRange(); fetchData(r.getStart(), r.getLength()); } } private void addTable() { // table: CellTable<DTO> table = new CellTable<DTO>(10); table.addColumn(new Column<DTO, String>(new TextCell()) { @Override public String getValue(DTO namespace) { return namespace.getName(); } }, "Name"); // pager: SimplePager<DTO> pager = new SimplePager<DTO>(table); table.setPager(pager); adapter = new MyAsyncAdapter(); adapter.addView(table); // does not make any difference: // adapter.updateDataSize(0, false); // adapter.updateDataSize(10, true); VerticalPanel vPanel = new VerticalPanel(); vPanel.add(table); vPanel.add(pager); RootLayoutPanel.get().add(vPanel); } // success-handler of my fetching AsyncCallback @Override public void onSuccess(List<DTO> data) { // AsyncCallback<List<DTO>> has start field adapter.updateViewData(start, data.size(), data); if(data.size() < length) adapter.updateDataSize(start + data.size(), true); } Regards J.

  • Loading of external SWF results in a "Could not find resource bundle messaging" error

    - by Leeron
    I'm using flash.display.Loader to load this example SWF as a use-case for loading SWFs that uses flex charting components in an application I'm working on. This is the code I'm using to load the swf: Main.mxml: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="onCreationComplete(event);"> <mx:Script> <![CDATA[ import mx.events.FlexEvent; import myLoaderClass; private function onCreationComplete( e:FlexEvent ):void { trace("Init!"); var l:myLoaderClass = new myLoaderClass(); this.addChild(l); } ]]> </mx:Script> </mx:Application> myLoaderClass: package { import mx.core.UIComponent; import flash.display.DisplayObject; import flash.display.DisplayObjectContainer; import flash.display.Loader; import flash.display.Sprite; import flash.display.StageAlign; import flash.display.StageScaleMode; import flash.events.Event; import flash.events.ProgressEvent; import flash.net.URLRequest; import flash.text.TextField; import flash.text.TextFieldType; import flash.utils.Dictionary; public class JittRunner extends UIComponent { private var displayedObjects:Dictionary; public function JittRunner():void { displayedObjects = new Dictionary(); if (stage) init(); else addEventListener(Event.ADDED_TO_STAGE, init); } private function init(e:Event = null):void { removeEventListener(Event.ADDED_TO_STAGE, init); var mLoader:Loader = new Loader(); var mRequest:URLRequest = new URLRequest('ChartSampler.swf'); mLoader.load(mRequest); } } } The thing is, the minute the swf is loaded I'm getting the following runtime error: Error: Could not find resource bundle messaging at mx.resources::ResourceBundle$/getResourceBundle()[C:\autobuild\3.5.0\frameworks\projects\framework\src\mx\resources\ResourceBundle.as:143] at mx.utils::Translator$cinit() at global$init() at mx.messaging.config::ServerConfig$cinit() at global$init() at _app_FlexInit$/init() at mx.managers::SystemManager/http://www.adobe.com/2006/flex/mx/internal::docFrameHandler()[C:\autobuild\3.5.0\frameworks\projects\framework\src\mx\managers\SystemManager.as:3217] at mx.managers::SystemManager/docFrameListener()[C:\autobuild\3.5.0\frameworks\projects\framework\src\mx\managers\SystemManager.as:3069] What am I doing wrong here?

  • Check Avaibility of a page before loading using jquery/ajax

    - by overcomer
    Is it possible check the Accessibility of a page before loading it? I have a form, running on mobile device using wireless connection. The problem is: not always this connection is avaible and i would like to alert the user when is doing a submit or an unload of the page. The problem is that the page contains elements doing redirect like this: <input type="button" value="MyText" onClick="script1;script2;...window.location='mylocation" /> If the user click on this button and the server is not achievable, i will recive some undesiderable errors. Also if I want to generalize my script i do not know the value of "mylocation" previously. The page contains elements to submit the Form also: <input type="submit" name="SUBMIT" value="MyValue" onClick="return eval('validationForm()')" /> For the submitting I'm using the ajaxForm plugin and it works quite well. This is a snippet of code: Thanks to your answer I found the solution to the problem. That's the code: function checkConnection(u,s){ $.ajax({ url:u, cache:false, timeout:3000, error: function(jqXHR, textStatus) { alert("Request failed: " + textStatus ); }, success: function() { eval(s); } }); } $(document).ready(function() { // part of the function that checks buttons with redirect // for any input that contain a redirect on onClick attribute ("window.locarion=") $("input[type=button]").each(function(){ var script = $(this).attr("onClick"); var url = ""; var position = script.indexOf("window.location") ; if (position >= 0) { // case of redirect url = script.substring(position+17, script.lenght); url = url.split("\'")[0]; url = "\'"+url+"\'"; // that's my url script = "\""+script+"\""; // that's the complete script $(this).attr("onClick","checkConnection("+url+","+script+")"); } }); // part of the function that checks the submit buttons (using ajaxForm plugin) var is_error = false; var options = { error: function() { if (alert("Error Message")==true) { } is_error = true; }, target: window.document, replaceTarget: is_error, timeout: 3000 }; $("#myForm").ajaxForm(options); }); I hope that this will be usefull.

But the volume of data is big I'm recieving an error "java.lang.OutOfMemoryError: Java heap space" I've tried to write in blobFields null values on each row of table. In this case, application works fine, memory doesn't go out of. I have a conclusion that the blob field which is marked as lazy (@Basic(fetch=FetchType.LAZY)) isn't lazy, actually! How can I solve the issie? Many thanks for advance.

  • Eager/Lazy loaded member always empty with JPA one-to-many relationship

    - by Kaleb Pederson
    I have two entities, a User and Role with a one-to-many relationship from user to role. Here's what the tables look like: mysql> select * from User; +----+-------+----------+ | id | name | password | +----+-------+----------+ | 1 | admin | admin | +----+-------+----------+ 1 row in set (0.00 sec) mysql> select * from Role; +----+----------------------+---------------+----------------+ | id | description | name | summary | +----+----------------------+---------------+----------------+ | 1 | administrator's role | administrator | Administration | | 2 | editor's role | editor | Editing | +----+----------------------+---------------+----------------+ 2 rows in set (0.00 sec) And here's the join table that was created: mysql> select * from User_Role; +---------+----------+ | User_id | roles_id | +---------+----------+ | 1 | 1 | | 1 | 2 | +---------+----------+ 2 rows in set (0.00 sec) And here's the subset of orm.xml that defines the tables and relationships: <entity class="User" name="User"> <table name="User" /> <attributes> <id name="id"> <generated-value strategy="AUTO" /> </id> <basic name="name"> <column name="name" length="100" unique="true" nullable="false"/> </basic> <basic name="password"> <column length="255" nullable="false" /> </basic> <one-to-many name="roles" fetch="EAGER" target-entity="Role" /> </attributes> </entity> <entity class="Role" name="Role"> <table name="Role" /> <attributes> <id name="id"> <generated-value strategy="AUTO"/> </id> <basic name="name"> <column name="name" length="40" unique="true" nullable="false"/> </basic> <basic name="summary"> <column name="summary" length="100" nullable="false"/> </basic> <basic name="description"> <column name="description" length="255"/> </basic> </attributes> </entity> Yet, despite that, when I retrieve the admin user, I get back an empty collection. I'm using Hibernate as my JPA provider and it shows the following debug SQL: select user0_.id as id8_, user0_.name as name8_, user0_.password as password8_ from User user0_ where user0_.name=? limit ? When the one-to-many mapping is lazy loaded, that's the only query that's made. This correctly retrieves the one admin user. I changed the relationship to use eager loading and then the following query is made in addition to the above: select roles0_.User_id as User1_1_, roles0_.roles_id as roles2_1_, role1_.id as id9_0_, role1_.description as descript2_9_0_, role1_.name as name9_0_, role1_.summary as summary9_0_ from User_Role roles0_ left outer join Role role1_ on roles0_.roles_id=role1_.id where roles0_.User_id=? Which results in the following results: +----------+-----------+--------+----------------------+---------------+----------------+ | User1_1_ | roles2_1_ | id9_0_ | descript2_9_0_ | name9_0_ | summary9_0_ | +----------+-----------+--------+----------------------+---------------+----------------+ | 1 | 1 | 1 | administrator's role | administrator | Administration | | 1 | 2 | 2 | editor's role | editor | Editing | +----------+-----------+--------+----------------------+---------------+----------------+ 2 rows in set (0.00 sec) Hibernate obviously knows about the roles, yet getRoles() still returns an empty collection. Hibernate also recognized the relationship sufficiently to put the data in the first place. What problems can cause these symptoms?

  • Error When Loading Images on Local Host Test Server

    - by ke4ktz
    I have a peculiar problem that I just can't seem to find an explanation. I'm working on an AngularJS site for our family and am integrating data from various web services. Currently I am working on the photos section which will integrate in photos from our Flickr account. I have a main page which lists the various photo sets and displays the set's primary photo along with the title. (Note: I'm using the Flickr 'extras' parameter to return the primary photo's URL in the API calls.) <div data-ng-repeat="p in vm.photoSets"> <a ng-href="#/photos/{{p.id}}"> <img ng-src="{{p.primary_photo_extras.url_s}}"></img> </a> <h4>{{p.title._content}}</h4> </div> When clicking on the photo, the routing will display a page with a list of all the photos from that set, showing the image and the title. <div data-ng-repeat="p in vm.photoSetData.photo"> <a ng-href="#/photos/{{vm.photoSetId}}/{{p.id}}" <img ng-src="{{p.url_s}}"></img> </a> <h4>{{p.title}}</h4> </div> Now, here's where the problem is occuring. When I upload the code to my public website on my hosting provider, everything works just fine. Both pages display their respective photos. However, when I attempt to run the site on my local system, either in MAMP or NodeJS (using http-server), the second page gives me an error for each image: Error: [$interpolate:interr] Can't interpolate: {{p.url_s}} Error: [$sce:insecurl] Blocked loading resource from url not allowed by $sceDelegate policy.

In fact, the image title does display! I've tested it with Firefox, Safari and Chrome...all three browsers fail. I cannot find any explanation as to why it would work remotely but fail locally. Also, the images show up on the first page, but not on the second, even though one of the images on the second page is the same image URL as on the first page. Even going directly to the second page, bypassing the first page, still fails. Any ideas on how to fix this? It would be nice to test locally without having to upload to the server each time I make a change. Update: I have shut off the $sce security to see if that was causing the issue. Although it resulted in turning the error off, the files still don't load on the local test server. I have used the developer tools' network monitor and it doesn't even show an attempt to retrieve the files. AngularJS appears to shut down the retrieval, although the correct path shows up in the DOM.

  • Multiset container appears to stop sorting

    - by Sarah
    I would appreciate help debugging some strange behavior by a multiset container. Occasionally, the container appears to stop sorting. This is an infrequent error, apparent in only some simulations after a long time, and I'm short on ideas. (I'm an amateur programmer--suggestions of all kinds are welcome.) My container is a std::multiset that holds Event structs: typedef std::multiset< Event, std::less< Event > > EventPQ; with the Event structs sorted by their double time members: struct Event { public: explicit Event(double t) : time(t), eventID(), hostID(), s() {} Event(double t, int eid, int hid, int stype) : time(t), eventID( eid ), hostID( hid ), s(stype) {} bool operator < ( const Event & rhs ) const { return ( time < rhs.time ); } double time; ... }; The program iterates through periods of adding events with unordered times to EventPQ currentEvents and then pulling off events in order. Rarely, after some events have been added (with perfectly 'legal' times), events start getting executed out of order. What could make the events ever not get ordered properly? (Or what could mess up the iterator?) I have checked that all the added event times are legitimate (i.e., all exceed the current simulation time), and I have also confirmed that the error does not occur because two events happen to get scheduled for the same time. I'd love suggestions on how to work through this. The code for executing and adding events is below for the curious: double t = 0.0; double nextTimeStep = t + EPID_DELTA_T; EventPQ::iterator eventIter = currentEvents.begin(); while ( t < EPID_SIM_LENGTH ) { // Add some events to currentEvents while ( ( *eventIter ).time < nextTimeStep ) { Event thisEvent = *eventIter; t = thisEvent.time; executeEvent( thisEvent ); eventCtr++; currentEvents.erase( eventIter ); eventIter = currentEvents.begin(); } t = nextTimeStep; nextTimeStep += EPID_DELTA_T; } void Simulation::addEvent( double et, int eid, int hid, int s ) { assert( currentEvents.find( Event(et) ) == currentEvents.end() ); Event thisEvent( et, eid, hid, s ); currentEvents.insert( thisEvent ); }

  • asp.net external form loading into jquery dialog submit button issue

    I am loading an external file 'contact_us.aspx' into a jquery dialog box. the external page contains a form. When the submit button is pressed it closes the dialog box and changes the page to contact_us.aspx. is my code correct or is there a different way of doing this. see my code below, thanks. This JS is in y masterpage: <script type="text/javascript"> $(document).ready(function() { var dialogOpts = { modal: true, bgiframe: true, autoOpen: false, height: 500, width: 500, open: function(type, data) { $(this).parent().appendTo(jQuery("form:first")); } } $("#genericContact").dialog(dialogOpts); //end dialog $('a.conactGeneric').click( function() { $("#genericContact").load("contact_us.aspx", [], function() { $("#genericContact").dialog("open"); } ); return false; } ); }); </script> The external file 'contact_us.aspx' which is loaded into the dialog box, when the link is clicked. <asp:Panel ID="pnlEnquiry" runat="server" DefaultButton="btn_Contact"> <asp:Label ID="lblError" CssClass="error" runat="server" Visible="false" Text=""></asp:Label> <div class="contact_element"> <label for="txtName">Your Name <span>*</span></label> <asp:TextBox CssClass="contact_field" ID="txtName" runat="server"></asp:TextBox> <asp:RequiredFieldValidator CssClass="contact_error" ControlToValidate="txtName" Display="Dynamic" ValidationGroup="valContact" ID="RequiredFieldValidator1" runat="server" ErrorMessage="Enter your name"></asp:RequiredFieldValidator> </div> <div class="contact_element"> <label for="txtName">Phone Number</label> <asp:TextBox CssClass="contact_field" ID="txtTel" runat="server"></asp:TextBox> <asp:RequiredFieldValidator CssClass="contact_error" ControlToValidate="txtTel" Display="Dynamic" ValidationGroup="valContact" ID="RequiredFieldValidator2" runat="server" ErrorMessage="Enter your phone number"></asp:RequiredFieldValidator> </div> <div class="contact_element"> <label for="txtEmail">Your Email <span>*</span></label> <asp:TextBox CssClass="contact_field" ID="txtEmail" runat="server"></asp:TextBox> <asp:RequiredFieldValidator CssClass="contact_error" ControlToValidate="txtEmail" Display="Dynamic" ValidationGroup="valContact" ID="RequiredFieldValidator3" runat="server" ErrorMessage="Enter your email address"></asp:RequiredFieldValidator> </div> <div class="contact_element"> <label for="txtQuestion">Question <span>*</span></label> <asp:TextBox TextMode="MultiLine" CssClass="contact_question" ID="txtQuestion" runat="server"></asp:TextBox> <asp:RequiredFieldValidator CssClass="contact_error" ControlToValidate="txtQuestion" Display="Dynamic" ValidationGroup="valContact" ID="RequiredFieldValidator4" runat="server" ErrorMessage="Enter your question"></asp:RequiredFieldValidator> </div> <div class="contact_chkbox"> <asp:CheckBox ID="chkNews" runat="server" Checked="true" Text="Receive our monthly newsletter" EnableTheming="false" /> </div> <span class="mandatory">* Required Field</span> <asp:LinkButton ID="btn_Contact" ToolTip="Submit" CssClass="submit_btn" ValidationGroup="valContact" runat="server" OnClick="SignUp" ></asp:LinkButton> <asp:RegularExpressionValidator CssClass="contact_error" ID="RegularExpressionValidator1" runat="server" ValidationExpression=".*@.{2,}\..{2,}" Display="Dynamic" ValidationGroup="valContact" ControlToValidate="txtEmail" ErrorMessage="Invalid email format."></asp:RegularExpressionValidator> <asp:ValidationSummary ID="ValidationSummary1" ValidationGroup="valContact" ShowMessageBox=true ShowSummary=false runat="server" /> </asp:Panel> <asp:Panel ID="pnlThanks" runat="server" Visible="false"> <h1>Thank you!</h1> </asp:Panel> code behind file: protected void SignUp(object sender, EventArgs e) { SmtpMail.SmtpServer = "localhost"; MailMessage myMail = new MailMessage(); //String myToEmail = MyDB.getScalar("select setting_value from [Website.Settings]"); ; //myMail.To = myToEmail; myMail.To = "[email protected]"; myMail.From = "[email protected]"; //myMail.Bcc = "[email protected]"; myMail.Subject = "Enquiry from the Naturetrek Site"; StringBuilder myContent = new StringBuilder(); myContent.Append("Name : " + txtName.Text + "\r\n"); myContent.Append("Email: " + txtEmail.Text + "\r\n"); myContent.Append("Telephone: " + txtTel.Text + "\r\n"); myContent.Append("\r\nTheir Question: \r\n" + txtQuestion.Text + "\r\n"); if (chkNews.Checked != true) { myContent.Append("Subscribed to newsletter: No"); } else { myContent.Append("Subscribed to newsletter: Yes"); } myContent.Append("\r\n"); myMail.Body = myContent.ToString(); SmtpMail.Send(myMail); pnlEnquiry.Visible = false; pnlThanks.Visible = true; }

  • Paging over a lazy-loaded collection with NHibernate

    - by HackedByChinese
    I read this article where Ayende states NHibernate can (compared to EF 4): Collection with lazy=”extra” – Lazy extra means that NHibernate adapts to the operations that you might run on top of your collections. That means that blog.Posts.Count will not force a load of the entire collection, but rather would create a “select count(*) from Posts where BlogId = 1” statement, and that blog.Posts.Contains() will likewise result in a single query rather than paying the price of loading the entire collection to memory. Collection filters and paged collections - this allows you to define additional filters (including paging!) on top of your entities collections, which means that you can easily page through the blog.Posts collection, and not have to load the entire thing into memory. So I decided to put together a test case. I created the cliché Blog model as a simple demonstration, with two classes as follows: public class Blog { public virtual int Id { get; private set; } public virtual string Name { get; set; } public virtual ICollection<Post> Posts { get; private set; } public virtual void AddPost(Post item) { if (Posts == null) Posts = new List<Post>(); if (!Posts.Contains(item)) Posts.Add(item); } } public class Post { public virtual int Id { get; private set; } public virtual string Title { get; set; } public virtual string Body { get; set; } public virtual Blog Blog { get; private set; } } My mappings files look like this: <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" default-access="property" auto-import="true" default-cascade="none" default-lazy="true"> <class xmlns="urn:nhibernate-mapping-2.2" name="Model.Blog, TestEntityFramework, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" table="Blogs"> <id name="Id" type="System.Int32, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="Id" /> <generator class="identity" /> </id> <property name="Name" type="System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="Name" /> </property> <property name="Type" type="System.Int32, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="Type" /> </property> <bag lazy="extra" name="Posts"> <key> <column name="Blog_Id" /> </key> <one-to-many class="Model.Post, TestEntityFramework, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" /> </bag> </class> </hibernate-mapping> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" default-access="property" auto-import="true" default-cascade="none" default-lazy="true"> <class xmlns="urn:nhibernate-mapping-2.2" name="Model.Post, TestEntityFramework, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" table="Posts"> <id name="Id" type="System.Int32, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="Id" /> <generator class="identity" /> </id> <property name="Title" type="System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="Title" /> </property> <property name="Body" type="System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="Body" /> </property> <many-to-one class="Model.Blog, TestEntityFramework, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" name="Blog"> <column name="Blog_id" /> </many-to-one> </class> </hibernate-mapping> My test case looks something like this: using (ISession session = Configuration.Current.CreateSession()) // this class returns a custom ISession that represents either EF4 or NHibernate { blogs = (from b in session.Linq<Blog>() where b.Name.Contains("Test") orderby b.Id select b); Console.WriteLine("# of Blogs containing 'Test': {0}", blogs.Count()); Console.WriteLine("Viewing the first 5 matching Blogs."); foreach (Blog b in blogs.Skip(0).Take(5)) { Console.WriteLine("Blog #{0} \"{1}\" has {2} Posts.", b.Id, b.Name, b.Posts.Count); Console.WriteLine("Viewing first 5 matching Posts."); foreach (Post p in b.Posts.Skip(0).Take(5)) { Console.WriteLine("Post #{0} \"{1}\" \"{2}\"", p.Id, p.Title, p.Body); } } } Using lazy="extra", the call to b.Posts.Count does do a SELECT COUNT(Id)... which is great. However, b.Posts.Skip(0).Take(5) just grabs all Posts for Blog.Id = ?id, and then LINQ on the application side is just taking the first 5 from the resulting collection. What gives?

  • Approaches for generic, compile-time safe lazy-load methods

    - by Aaronaught
    Suppose I have created a wrapper class like the following: public class Foo : IFoo { private readonly IFoo innerFoo; public Foo(IFoo innerFoo) { this.innerFoo = innerFoo; } public int? Bar { get; set; } public int? Baz { get; set; } } The idea here is that the innerFoo might wrap data-access methods or something similarly expensive, and I only want its GetBar and GetBaz methods to be invoked once. So I want to create another wrapper around it, which will save the values obtained on the first run. It's simple enough to do this, of course: int IFoo.GetBar() { if ((Bar == null) && (innerFoo != null)) Bar = innerFoo.GetBar(); return Bar ?? 0; } int IFoo.GetBaz() { if ((Baz == null) && (innerFoo != null)) Baz = innerFoo.GetBaz(); return Baz ?? 0; } But it gets pretty repetitive if I'm doing this with 10 different properties and 30 different wrappers. So I figured, hey, let's make this generic: T LazyLoad<T>(ref T prop, Func<IFoo, T> loader) { if ((prop == null) && (innerFoo != null)) prop = loader(innerFoo); return prop; } Which almost gets me where I want, but not quite, because you can't ref an auto-property (or any property at all). In other words, I can't write this: int IFoo.GetBar() { return LazyLoad(ref Bar, f => f.GetBar()); // <--- Won't compile } Instead, I'd have to change Bar to have an explicit backing field and write explicit getters and setters. Which is fine, except for the fact that I end up writing even more redundant code than I was writing in the first place. Then I considered the possibility of using expression trees: T LazyLoad<T>(Expression<Func<T>> propExpr, Func<IFoo, T> loader) { var memberExpression = propExpr.Body as MemberExpression; if (memberExpression != null) { // Use Reflection to inspect/set the property } } This plays nice with refactoring - it'll work great if I do this: return LazyLoad(f => f.Bar, f => f.GetBar()); But it's not actually safe, because someone less clever (i.e. myself in 3 days from now when I inevitably forget how this is implemented internally) could decide to write this instead: return LazyLoad(f => 3, f => f.GetBar()); Which is either going to crash or result in unexpected/undefined behaviour, depending on how defensively I write the LazyLoad method. So I don't really like this approach either, because it leads to the possibility of runtime errors which would have been prevented in the first attempt. It also relies on Reflection, which feels a little dirty here, even though this code is admittedly not performance-sensitive. Now I could also decide to go all-out and use DynamicProxy to do method interception and not have to write any code, and in fact I already do this in some applications. But this code is residing in a core library which many other assemblies depend on, and it seems horribly wrong to be introducing this kind of complexity at such a low level. Separating the interceptor-based implementation from the IFoo interface by putting it into its own assembly doesn't really help; the fact is that this very class is still going to be used all over the place, must be used, so this isn't one of those problems that could be trivially solved with a little DI magic. The last option I've already thought of would be to have a method like: T LazyLoad<T>(Func<T> getter, Action<T> setter, Func<IFoo, T> loader) { ... } This option is very "meh" as well - it avoids Reflection but is still error-prone, and it doesn't really reduce the repetition that much. It's almost as bad as having to write explicit getters and setters for each property. Maybe I'm just being incredibly nit-picky, but this application is still in its early stages, and it's going to grow substantially over time, and I really want to keep the code squeaky-clean. Bottom line: I'm at an impasse, looking for other ideas. Question: Is there any way to clean up the lazy-loading code at the top, such that the implementation will: Guarantee compile-time safety, like the ref version; Actually reduce the amount of code repetition, like the Expression version; and Not take on any significant additional dependencies? In other words, is there a way to do this just using regular C# language features and possibly a few small helper classes? Or am I just going to have to accept that there's a trade-off here and strike one of the above requirements from the list?

  • Image not loading onto JPanel?

    - by None None
    I have been trying to figure out how to add an image to a JPanel as a background, but still have complete control over the placing of JButtons, JLabels, and etc. This is one method I found, but it is crashing and not loading the image or buttons. Here is the code: import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.JButton; import java.awt.BorderLayout; import java.awt.FlowLayout; import java.awt.GridLayout; public class PanelDemo extends JFrame { private static final long serialVersionUID = 1L; private JButton btn1 = new JButton("EASY"); private JButton btn2 = new JButton("MEDIUM"); private JButton btn3 = new JButton("HARD"); private JButton btn4 = new JButton("High Score"); public PanelDemo() { super("Image Panel Demo"); JPanel panel = new ImagePanel( new FlowLayout(FlowLayout.CENTER, 50, 180)); JPanel panelbtn = new JPanel(new GridLayout(4, 1)); btn1.setBackground(new java.awt.Color(0, 0, 0)); btn1.setFont(new java.awt.Font("Showcard Gothic", 1, 24)); btn1.setForeground(new java.awt.Color(0, 255, 102)); btn2.setBackground(new java.awt.Color(0, 0, 0)); btn2.setFont(new java.awt.Font("Showcard Gothic", 1, 24)); btn2.setForeground(new java.awt.Color(0, 255, 102)); btn3.setBackground(new java.awt.Color(0, 0, 0)); btn3.setFont(new java.awt.Font("Showcard Gothic", 1, 24)); btn3.setForeground(new java.awt.Color(0, 255, 102)); btn4.setBackground(new java.awt.Color(0, 0, 0)); btn4.setFont(new java.awt.Font("Showcard Gothic", 1, 24)); btn4.setForeground(new java.awt.Color(0, 255, 102)); panel.add(panelbtn); panelbtn.add(btn1); panelbtn.add(btn2); panelbtn.add(btn3); panelbtn.add(btn4); add(panel, BorderLayout.CENTER); setSize(640, 480); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } public static void main(String... args) { new PanelDemo().setVisible(true); } } ImagePanel.java import java.awt.Graphics; import java.awt.Image; import java.awt.LayoutManager; import javax.swing.ImageIcon; import javax.swing.JPanel; public class ImagePanel extends JPanel { private static final long serialVersionUID = 1L; String imageFile = "/rsc/img/background.jpg"; public ImagePanel() { super(); } public ImagePanel(String image) { super(); this.imageFile = image; } public ImagePanel(LayoutManager layout) { super(layout); } public void paintComponent(Graphics g) { ImageIcon imageicon = new ImageIcon(getClass().getResource(imageFile)); Image image = imageicon.getImage(); super.paintComponent(g); if (image != null) g.drawImage(image, 0, 0, getWidth(), getHeight(), this); } } Error: Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at javax.swing.ImageIcon.<init>(Unknown Source) at ImagePanel.paintComponent(ImagePanel.java:27) at javax.swing.JComponent.paint(Unknown Source) at javax.swing.JComponent.paintChildren(Unknown Source) at javax.swing.JComponent.paint(Unknown Source) at javax.swing.JComponent.paintChildren(Unknown Source) at javax.swing.JComponent.paint(Unknown Source) at javax.swing.JLayeredPane.paint(Unknown Source) at javax.swing.JComponent.paintChildren(Unknown Source) at javax.swing.JComponent.paintToOffscreen(Unknown Source) at javax.swing.RepaintManager$PaintManager.paintDoubleBuffered(Unknown Source) at javax.swing.RepaintManager$PaintManager.paint(Unknown Source) at javax.swing.RepaintManager.paint(Unknown Source) at javax.swing.JComponent.paint(Unknown Source) at java.awt.GraphicsCallback$PaintCallback.run(Unknown Source) at sun.awt.SunGraphicsCallback.runOneComponent(Unknown Source) at sun.awt.SunGraphicsCallback.runComponents(Unknown Source) at java.awt.Container.paint(Unknown Source) at java.awt.Window.paint(Unknown Source) at javax.swing.RepaintManager$3.run(Unknown Source) at javax.swing.RepaintManager$3.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain$1.doIntersectionPrivilege(Unknown Source) at javax.swing.RepaintManager.paintDirtyRegions(Unknown Source) at javax.swing.RepaintManager.paintDirtyRegions(Unknown Source) at javax.swing.RepaintManager.prePaintDirtyRegions(Unknown Source) at javax.swing.RepaintManager.access$1000(Unknown Source) at javax.swing.RepaintManager$ProcessingRunnable.run(Unknown Source) at java.awt.event.InvocationEvent.dispatch(Unknown Source) at java.awt.EventQueue.dispatchEventImpl(Unknown Source) at java.awt.EventQueue.access$200(Unknown Source) at java.awt.EventQueue$3.run(Unknown Source) at java.awt.EventQueue$3.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain$1.doIntersectionPrivilege(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source) Also, if anyone knows of a better way to put a background image on a JPanel, pease do tell.

  • Many-to-one relation exception due to closed session after loading

    - by Nick Thissen
    Hi, I am using NHibernate (version 1.2.1) for the first time so I wrote a simple test application (an ASP.NET project) that uses it. In my database I have two tables: Persons and Categories. Each person gets one category, seems easy enough. | Persons | | Categories | |--------------| |--------------| | Id (PK) | | Id (PK) | | Firstname | | CategoryName | | Lastname | | CreatedTime | | CategoryId | | UpdatedTime | | CreatedTime | | Deleted | | UpdatedTime | | Deleted | The Id, CreatedTime, UpdatedTime and Deleted attributes are a convention I use in all my tables, so I have tried to bring this fact into an additional abstraction layer. I have a project DatabaseFramework which has three important classes: Entity: an abstract class that defines these four properties. All 'entity objects' (in this case Person and Category) must inherit Entity. IEntityManager: a generic interface (type parameter as Entity) that defines methods like Load, Insert, Update, etc. NHibernateEntityManager: an implementation of this interface using NHibernate to do the loading, saving, etc. Now, the Person and Category classes are straightforward, they just define the attributes of the tables of course (keeping in mind that four of them are in the base Entity class). Since the Persons table is related to the Categories table via the CategoryId attribute, the Person class has a Category property that holds the related category. However, in my webpage, I will also need the name of this category (CategoryName), for databinding purposes for example. So I created an additional property CategoryName that returns the CategoryName property of the current Category property, or an empty string if the Category is null: Namespace Database Public Class Person Inherits DatabaseFramework.Entity Public Overridable Property Firstname As String Public Overridable Property Lastname As String Public Overridable Property Category As Category Public Overridable ReadOnly Property CategoryName As String Get Return If(Me.Category Is Nothing, _ String.Empty, _ Me.Category.CategoryName) End Get End Property End Class End Namespace I am mapping the Person class using this mapping file. The many-to-one relation was suggested by Yads in another thread: <id name="Id" column="Id" type="int" unsaved-value="0"> <generator class="identity" /> </id> <property name="CreatedTime" type="DateTime" not-null="true" /> <property name="UpdatedTime" type="DateTime" not-null="true" /> <property name="Deleted" type="Boolean" not-null="true" /> <property name="Firstname" type="String" /> <property name="Lastname" type="String" /> <many-to-one name="Category" column="CategoryId" class="NHibernateWebTest.Database.Category, NHibernateWebTest" /> (I can't get it to show the root node, this forum hides it, I don't know how to escape the html-like tags...) The final important detail is the Load method of the NHibernateEntityManager implementation. (This is in C# as it's in a different project, sorry about that). I simply open a new ISession (ISessionFactory.OpenSession) in the GetSession method and then use that to fill an EntityCollection(Of TEntity) which is just a collection inheriting System.Collections.ObjectModel.Collection(Of T). public virtual EntityCollection< TEntity Load() { using (ISession session = this.GetSession()) { var entities = session .CreateCriteria(typeof (TEntity)) .Add(Expression.Eq("Deleted", false)) .List< TEntity (); return new EntityCollection< TEntity (entities); } } (Again, I can't get it to format the code correctly, it hides the generic type parameters, probably because it reads the angled symbols as a HTML tag..? If you know how to let me do that, let me know!) Now, the idea of this Load method is that I get a fully functional collection of Persons, all their properties set to the correct values (including the Category property, and thus, the CategoryName property should return the correct name). However, it seems that is not the case. When I try to data-bind the result of this Load method to a GridView in ASP.NET, it tells me this: Property accessor 'CategoryName' on object 'NHibernateWebTest.Database.Person' threw the following exception:'Could not initialize proxy - the owning Session was closed.' The exception occurs on the DataBind method call here: public virtual void LoadGrid() { if (this.Grid == null) return; this.Grid.DataSource = this.Manager.Load(); this.Grid.DataBind(); } Well, of course the session is closed, I closed it via the using block. Isn't that the correct approach, should I keep the session open? And for how long? Can I close it after the DataBind method has been run? In each case, I'd really like my Load method to just return a functional collection of items. It seems to me that it is now only getting the Category when it is required (eg, when the GridView wants to read the CategoryName, which wants to read the Category property), but at that time the session is closed. Is that reasoning correct? How do I stop this behavior? Or shouldn't I? And what should I do otherwise? Thanks!

  • Cleaning your BizTalk Build Server
