  • How do I use WS-Security with WCF?

    - by Jonathan Allen
    Below is the style of header I need to create. I am expected to use either a public/private key or a SSL style certificate. I don't know for certain, but I think my counter-party is using some form of Java. <soap-env:Header> <wsse:Security xmlns:wsse="http://schemas.xmlsoap.org/ws/2002/04/secext"> <ds:Signature xmlns:ds="http://www.w3.org/2000/09/xmldsig#"> <ds:SignedInfo xmlns:ds="http://www.w3.org/2000/09/xmldsig#"> <ds:CanonicalizationMethod Algorithm="http://www.w3.org/2001/10/xml-exc-c14n#" /> <ds:SignatureMethod Algorithm="http://www.w3.org/2000/09/xmldsig#rsa-sha1" /> <ds:Reference URI="#secinfo"> <ds:DigestMethod Algorithm="http://www.w3.org/2000/09/xmldsig#sha1" /> <ds:DigestValue>xxxxxxxxxxxxx</ds:DigestValue> <ds:Transforms> <ds:Transform Algorithm="http://www.w3.org/TR/1999/REC-xpath-19991116"> <ds:XPath>//*[@id='secinfo']/child::*/text()</ds:XPath> </ds:Transform> </ds:Transforms> </ds:Reference> </ds:SignedInfo> <ds:SignatureValue>xxxxxxxxxxds:SignatureValue> <ds:KeyInfo> <ds:KeyName>xxxxxxx</ds:KeyName> </ds:KeyInfo> </ds:Signature> <t:UsernameToken xmlns:t="http://schemas.xmlsoap.org/ws/2002/04/secext" id="secinfo"> <t:UserInfo>USER=xxxx;CORR=xxxx;TIMESTAMP=201003161916</t:UserInfo> </t:UsernameToken> </wsse:Security> </soap-env:Header>

  • Why is Dispatcher.Invoke not triggering UI update?

    - by Brandon
    I am trying to reuse a UserControl and also borrow some logic that keeps track of progress. I'll try and simplify things. MyWindow.xaml includes a MyUserControl. MyUserControl has its own progress indicator (Formatting in progress..., Copying files..., etc.) and I'd like to mirror this progress somewhere in the MyWindow form. But, the user control has some logic I don't quite understand. I've read and read but I still don't understand the Dispatcher. Here's a summary of the logic in the user control that updates the progress. this.Dispatcher.Invoke(DispatcherPriority.Input, (Action)(() => { DAProgressIndicator = InfiniteProgress.AddNewInstanceToControl(StatusGrid, new SolidColorBrush(new Color() { A = 170, R = 128, G = 128, B = 128 }), string.Empty); DAProgressIndicator.Message = MediaCardAdminRes.ActivatingCard; ActivateInProgress = true; })); I thought I'd be smart and add an event to MyUserControl that would be called in the ActivateInProgress property set logic. public bool ActivateInProgress { get { return _activateInProgress; } set { _activateInProgress = value; if (ActivateInProgressHandler != null) { ActivateInProgressHandler(value); } } } I'm setting the ActivateInProgressHandler within the MyWindow constructor to the following method that sets the view model property that is used for the window's own progress indicator. private void SetActivation(bool activateInProgress) { viewModel.ActivationInProgress = activateInProgress; } However, the window's progress indicator never changes. So, I'm convinced that the Dispatcher.Invoke is doing something that I don't understand. If I put a message box inside the SetActivation method, the thread blocks and the window's progress indicator is updated. I understand basic threads but this whole Dispatcher thing is new to me. What am I missing?

  • Explicit behavior with checks vs. implicit behavior

    - by Silviu
    I'm not sure how to construct the question but I'm interested to know what do you guys think of the following situations and which one would you prefer. We're working at a client-server application with winforms. And we have a control that has some fields automatically calculated upon filling another field. So we're having a field currency which when filled by the user would determine an automatic filling of another field, maybe more fields. When the user fills the currency field, a Currency object would be retrieved from a cache based on the string introduced by the user. If entered currency is not found in the cache a null reference is returned by the cache object. Further down when asking the application layer to compute the other fields based on the currency, given a null currency a null specific field would be returned. This way the default, implicit behavior is to clear all fields. Which is the expected behavior. What i would call the explicit implementation would be to verify that the Currency object is null in which case the depending fields are cleared explicitly. I think that the latter version is more clear, less error prone and more testable. But it implies a form of redundancy. The former version is not as clear and it implies a certain behavior from the application layer which is not expressed in the tests. Maybe in the lower layer tests but when the need arises to modify the lower layers, so that given a null currency something else should be returned, i don't think a test that says just that without a motivation is going to be an impediment for introducing a bug in upper layers. What do you guys think?

  • How do I eliminate Error 3002?

    - by Andrew
    Say I have the following table definitions in SQL Server 2008: CREATE TABLE Person (PersonId INT IDENTITY NOT NULL PRIMARY KEY, Name VARCHAR(50) NOT NULL, ManyMoreIrrelevantColumns VARCHAR(MAX) NOT NULL) CREATE TABLE Model (ModelId INT IDENTITY NOT NULL PRIMARY KEY, ModelName VARCHAR(50) NOT NULL, Description VARCHAR(200) NULL) CREATE TABLE ModelScore (ModelId INT NOT NULL REFERENCES Model (ModelId), Score INT NOT NULL, Definition VARCHAR(100) NULL, PRIMARY KEY (ModelId, Score)) CREATE TABLE PersonModelScore (PersonId INT NOT NULL REFERENCES Person (PersonId), ModelId INT NOT NULL, Score INT NOT NULL, PRIMARY KEY (PersonId, ModelId), FOREIGN KEY (ModelId, Score) REFERENCES ModelScore (ModelId, Score)) The idea here is that each Person may have only one ModelScore per Model, but each Person may have a score for any number of defined Models. As far as I can tell, this SQL should enforce these constraints naturally. The ModelScore has a particular "meaning," which is contained in the Definition. Nothing earth-shattering there. Now, I try translating this into Entity Framework using the designer. After updating the model from the database and doing some editing, I have a Person object, a Model object, and a ModelScore object. PersonModelScore, being a join table, is not an object but rather is included as an association with some other name (let's say ModelScorePersonAssociation). The mapping details for the association are as follows: - Association - Maps to PersonModelScore - ModelScore ModelId : Int32 <=> ModelId : int Score : Int32 <=> Score : int - Person PersonId : Int32 <=> PersonId : int On the right-hand side, the ModelId and PersonId values have primary key symbols, but the Score value does not. Upon compilation, I get: Error 3002: Problem in Mapping Fragment starting at line 5190: Potential runtime violation of table PersonModelScore's keys (PersonModelScore.ModelId, PersonModelScore.PersonId): Columns (PersonModelScore.PersonId, PersonModelScore.ModelId) are mapped to EntitySet ModelScorePersonAssociation's properties (ModelScorePersonAssociation.Person.PersonId, ModelScorePersonAssociation.ModelScore.ModelId) on the conceptual side but they do not form the EntitySet's key properties (ModelScorePersonAssociation.ModelScore.ModelId, ModelScorePersonAssociation.ModelScore.Score, ModelScorePersonAssociation.Person.PersonId). What have I done wrong in the designer or otherwise, and how can I fix the error? Many thanks!

  • BreezingForms Integrator Finalize Code and $this->execPieceByName('ff_InitLib');

    - by nickyt
    I've started working on a Joomla! project (I'm mainly a C#/ASP.NET kind a guy). I'm using BreezingForms and have created forms, got them working, but now I need to do some additional code in the "Finalize Code" section. I need to access form elements via BreezingForms(FacileForms) API. Here's what I'm doing, but it chokes: $this->execPieceByName('ff_SubmitLib'); // Is this necessary? // load the standard Facile Forms library $this->execPieceByName('ff_InitLib'); // page breaks here. // get the name of the uploaded file $filename = ff_getSubmit('someUploadedFile'); Now I don't know what goes wrong. The page posts back blank. I'm not sure how to debug this in Joomla. I currently do not have access to the server to debug, so I would need to debug remotely at runtime (not ideal I know). My account is of type Administrator for the Joomla backend. As far as I know all the plugins/modules are installed. Any ideas?

  • Open Source Web Frameworks : Security

    - by trappedIntoCode
    How secure are popular open source web frameworks? I am particularly interested in popular frameworks like Rails and DJango. If I am building a site which is going to do heavy e-commerce, is it Ok to use frameworks like DJango and Satchmo? Is security compromised because their open architecture ? I know being OS does not mean being down right open to hackers, Linux uses superb authentication mechanism, but web is a different game. What can be done in this regard? UPDATE: Thanks for answers guys. I understand that I will have to find a suitable hosting service for a secure e-commerce application and that additional layers of security will be needed. I understand that Django and Rails have been designed keeping security aspects in mind, the most common form attacks like XSS, Injections etc. (Django book has a ch on Security) I was expecting comments from security Gurus. If you are a security Guru, would you recommend an important site, which is likely going to be popular, to be built on DJango or Rails?

  • SQL statement with datetimepicker

    - by David Archer
    This should hopefully be a simple one. When using a date time picker in a windows form, I want an SQL statement to be carried out, like so: string sql = "SELECT * FROM Jobs WHERE JobDate = '" + dtpJobDate.Text + "'"; Unfortunately, this doesn't actually provide any results because the JobDate field is stored as a DateTime value. I'd like to be able to search for all records that are on this date, no matter what the time stored may be, any help? New query: SqlDataAdapter da2 = new SqlDataAdapter(); SqlCommand cmd = new SqlCommand(); cmd.CommandText = "SELECT * FROM Jobs WHERE JobDate >= @p_StartDate AND JobDate < @p_EndDate"; cmd.Parameters.Add ("@p_StartDate", SqlDbType.DateTime).Value = dtpJobDate.Value.Date; cmd.Parameters.Add ("@p_EndDate", SqlDbType.DateTime).Value = dtpJobDate.Value.Date.AddDays(1); cmd.Connection = conn; da2.SelectCommand = cmd; da2.Fill(dt); dgvJobDiary.DataSource = dt; Huge thanks for all the help!

  • Dynamically created "CheckBoxList" in placeholder controls throwing null reference exception error d

    - by newName
    I have a web form that will dynamically create a number of checkboxlist filled with data based on the number of row in database. Then this is added to a placeholder to be displayed. theres a button when clicked, will add the selected check boxes value into database but right now when the button is clicked and after the postback, the page will show the error "System.NullReferenceException". the following code is written in Page_Load in (!Page.IsNotPostBack) and in a loop that will dynamically create a number of checkboxlist: CheckBoxLis chkContent = new CheckBoxList(); chkContent.ID = chkIDString; //chkIDString is an incremental int based on the row count chkContent.RepeatDirection = RepeatDirection.Horizontal; foreach (List<t> contentList in List<t>) //data retrieved as List<t> using LINQ { ListItem contents = new ListItem(); contents.Text = contentList.Title; contents.Value = contentList.contentID.ToString(); chkContent.Items.Add(contents); } plcSchool.Controls.Add(chkContent); //plcSchool is my placeholder plcSchool.Controls.Add(new LiteralControl("<br>")); protected void btnAdd_Click(object sender, EventArgs e) { CheckBoxList cbl = Page.FindControl("chkContent4") as CheckBoxList; Response.Write(cbl.SelectedValue.ToString()); // now im just testing to get the value from one of the checkboxlist } Anyone able to help, as it seems the controls are not recreated after the postback, therefore it can't find the control and throwing the null reference exception.

  • Any one like me who still believes in AspNet Web forms? Or has evryone switched to MVC

    - by The_AlienCoder
    After years mastering Aspnet webforms I recently decided to try out ASpnet MVC. Naturally my first action was to google 'Aspnet webforms vs Aspnet MVC'. I hoped to get an honest comparison of the two development techniques and guidelines on when to use which one. ..But I was completely turned off by the MVC proponents. In almost every post on the net comparing the two 'platforms' the MVC camp is simply bashing webform developers like me. They go on and on about how wrong and stupid using webforms is. As if what we have been doing the past decade has been pointless - all those websites built(& still running), all those clever controls, the mighty gridview..ALL POINTLESS ! Karl Seguin especially with his stupid webforms rant really turned me off. If his intention was to convert people like me he did the oposite and made me defensive. If anything I am now convinced that the webforms approach is better. consider the following All the critical shortcomings of aspnet webforms have now been Addressed in visual studio 2010 with Aspnet 4.0.- Cleaner html, cleaner control IDs, friendly urls, leaner viewstate etc Why would any one want to implement the mighty gridview and other wonderful controls from scratch ? In MVC you have to do this yourself because ABSTRACTION IS PLAIN STUPID- Instead of writing loops why not just code using 1s and 0s then? A stateless web is a WEAKNESS so why would anyone want to get rid of viewstate? Everyone would like a better implementation but getting rid of it is a step backwards not forward. Unit testing is great but not a critical requirement for most web projects. I thought inline codes were dead with asp. But now they are back and fashionable - Thanks to MVC. I dont know about you people but codebehind was REVOLUTIONARY. Ive had the Ajax Update panel do so many wonderful things without writing a line of code so why demonise it? Ive succesfully implemented a chat client, IM client and Status bar using nothing but the update panel and script manager.Ofcourse you cant use it for everything but most of the time its appropriate. And finally the last word from JQUERY - 'Write less do more !' - That's what webforms is all about ! So Am I the only who still believes in webforms(and it getting better as Aspnet 4.0 has shown) or will it be dead and gone a few years from now like asp? I mean if inline coding is 'the future' why not just switch to PHP !

  • TinyMCE is glitchy in IE8

    - by Force Flow
    I'm using the jQuery version of TinyMCE 3.3.9.3 In firefox, it works fine (10 sec video depicting it in use): http://www.youtube.com/watch?v=TrAE0igfT3I In IE8 (in IE8 standards mode), I can't type or click any buttons. However, if I use ctrl+v to paste, then I can start typing, but the buttons still don't work (a 45 sec video depicting it in use): http://www.youtube.com/watch?v=iBSRlE8D8F4 The jQuery TinyMCE demo on TinyMCE's site works for me in IE8. Here's the init code: $().ready(function(){ function tinymce_focus(){ $('.defaultSkin table.mceLayout').css({'border-color' : '#6478D7'}); $('.defaultSkin table.mceLayout tr.mceFirst td').css({'border-top-color' : '#6478D7'}); $('.defaultSkin table.mceLayout tr.mceLast td').css({'border-bottom-color' : '#6478D7'}); } function tinymce_blur(){ $('.defaultSkin table.mceLayout').css({'border-color' : '#93a6e1'}); $('.defaultSkin table.mceLayout tr.mceFirst td').css({'border-top-color' : '#93a6e1'}); $('.defaultSkin table.mceLayout tr.mceLast td').css({'border-bottom-color' : '#93a6e1'}); } $('textarea.tinymce').tinymce({ script_url : 'JS/tinymce/tiny_mce.js', theme : "advanced", mode : "exact", theme : "advanced", invalid_elements : "b,i,iframe,font,input,textarea,select,button,form,fieldset,legend,script,noscript,object,embed,table,img,a,h1,h2,h3,h4,h5,h6", //theme options theme_advanced_buttons1 : "cut,copy,paste,pastetext,pasteword,selectall,|,undo,redo,|,cleanup,removeformat,|", theme_advanced_buttons2 : "bold,italic,underline,|,bullist,numlist,|,forecolor,backcolor,|", theme_advanced_buttons3 : "", theme_advanced_buttons4 : "", theme_advanced_toolbar_location : "top", theme_advanced_toolbar_align : "left", theme_advanced_statusbar_location : "none", theme_advanced_resizing : false, //plugins plugins : "inlinepopups,paste", dialog_type : "modal", paste_auto_cleanup_on_paste : true, setup: function(ed){ ed.onInit.add(function(ed){ //check for addEventListener -- primarily supported by firefox only var edDoc = ed.getDoc(); if ("addEventListener" in edDoc){ edDoc.addEventListener("focus", function(){ tinymce_focus(); }, false); edDoc.addEventListener("blur", function(){ tinymce_blur(); }, false); } }); } }); }); Any ideas as to why it's not working in IE8?

  • Creating a Blog ruby on Rails - Problem Deleting Comments

    - by bgadoci
    As I always type I am new to rails and programming in general so go easy. Thanks in advance. I have successfully followed the initial tutorial from Ryan Bates on how to build a weblog in 15 minutes. If you don't know this tutorial takes you through creating posts and allowing for comments on those post. It even introduces AJAX through the creating and displaying comments on the posts show.html.erb page. All works great. Here's the hiccup, when Ryan takes you though this tutorial he clears out the comments_controller and only shows the code for creating comments. I am trying to add back the ability to edit and destroy comments. Can't see to get it to work, keeps deleting the actual post not the comment (log shows that I keep sending DELETE request to PostsController). Here is my code: class CommentsController < ApplicationController def create @post = Post.find(params[:post_id]) @comment = @post.comments.create!(params[:comment]) respond_to do |format| format.html { redirect_to @post } format.js end end def destroy @comment = Comment.find(params[:id]) @comment.destroy respond_to do |format| format.html { redirect_to(posts_url) } format.xml { head :ok } end end end /views/posts/show.html.erb <%= render :partial => @post %> <p> <%= link_to 'Edit', edit_post_path (@post) %> | <%= link_to 'Destroy', @post, :method => :delete, :confirm => "Are you sure?" %> | <%= link_to 'See All Posts', posts_path %> </p> <h2>Comments</h2> <div id="comments"> <%= render :partial => @post.comments %> </div> <% remote_form_for [@post, Comment.new] do |f| %> <p> <%= f.label :body, "New Comment" %><br/> <%= f.text_area :body %> </p> <p> <%= f.submit "Add Comment" %></p> <% end %> /views/comments/_comment.html.erb <% div_for comment do %> <p> <strong>Posted <%= time_ago_in_words(comment.created_at) %> ago </strong><br/> <%= h(comment.body) %><br/> <%= link_to 'Destroy', @comments, :method => :delete, :confirm => "Are you sure?" %> </p> <% end %>

  • Qt: Force QWebView to click on a web element, even one not visible on the window

    - by Pirate for Profit
    So let's say I'm trying to click a link in the QWebView, here is what I have: // extending QWebView void MyWebView::click(const QString &selectorQuery) { QWebElement el = this->page()->mainFrame()->findFirstElement(selectorQuery); if (!el) return; el.setFocus(); QMouseEvent pressEvent(QMouseEvent::MouseButtonPress, el.geometry().center(), Qt::MouseButton::LeftButton, Qt::LeftButton, Qt::NoModifier); QCoreApplication::sendEvent(this, &pressEvent); QMouseEvent releaseEvent(QMouseEvent::MouseButtonRelease, el.geometry().center(), Qt::MouseButton::LeftButton, Qt::LeftButton, Qt::NoModifier); QCoreApplication::sendEvent(this, &releaseEvent); } And you call it as so: myWebView->click("a[href]"); // will click first link on page myWebView->click("input[type=submit]"); // submits a form THE ONLY PROBLEM IS: if the element is not visible in the window, it is impossible to click. What I mean is if you have to scroll down to see it, you can't click it. I imagine this has to do with the geometry, since the element doesn't show up on the screen it can't do the math to click it right. Any ideas to get around this? Maybe some way to make the window behave like a billion x billion pixels but still look 200x200?

  • Java Generics: Dealing with an intermediate unknown type

    - by Matt
    I am trying to figure out a way to deal with a particular problem in a type safe manner, or to put it more specifically without any explicit casts. I have a class that takes in a generic request and returns a generic response like such: public class RetrievalProcessor<Req extends Request, Resp> implements RequestProcessor<Req, Resp>{ private Dao<Req> dao; private RawResponseTransformer<Resp> transformer; @Override public Resp process(Req request) { return transformer.transformResponse(dao.retrieveRawResponse(request)); } } My problem is the following. My Dao object can be many different things REST, JDBC, some other proprietary object. I can't be certain of the type of object that the Dao will return. I do know the type of object my caller would like and that is the Resp type on the generic, and the job of the RawResponseTransformer is to transform that Dao response into something that the caller can consume. The problem I have is I can't figure out a way that feels clean to do that. I have considered putting the intermediate type as part of the definition of the class, but it doesn't seem like the caller should know, or really care, what the intermediate form is. Hoping someone might have a good clean idea for handling this.

  • Progress Bar design patterns?

    - by shoosh
    The application I'm writing performs a length algorithm which usually takes a few minutes to finish. During this time I'd like to show the user a progress bar which indicates how much of the algorithm is done as precisely as possible. The algorithm is divided into several steps, each with its own typical timing. For instance- initialization (500 milli-sec) reading inputs (5 sec) step 1 (30 sec) step 2 (3 minutes) writing outputs (7 sec) shutting down (10 milli-sec) Each step can report its progress quite easily by setting the range its working on, say [0 to 150] and then reporting the value it completed in its main loop. What I currently have set up is a scheme of nested progress monitors which form a sort of implicit tree of progress reporting. All progress monitors inherit from an interface IProgressMonitor: class IProgressMonitor { public: void setRange(int from, int to) = 0; void setValue(int v) = 0; }; The root of the tree is the ProgressMonitor which is connected to the actual GUI interface: class GUIBarProgressMonitor : public IProgressMonitor { GUIBarProgressMonitor(ProgressBarWidget *); }; Any other node in the tree are monitors which take control of a piece of the parent progress: class SubProgressMonitor : public IProgressMonitor { SubProgressMonitor(IProgressMonitor *parent, int parentFrom, int parentLength) ... }; A SubProgressMonitor takes control of the range [parentFrom, parentFrom+parentLength] of its parent. With this scheme I am able to statically divide the top level progress according to the expected relative portion of each step in the global timing. Each step can then be further subdivided into pieces etc' The main disadvantage of this is that the division is static and it gets painful to make changes according to variables which are discovered at run time. So the question: are there any known design patterns for progress monitoring which solve this issue?

  • Spring HandlerInterceptor or Spring Security to protect resource

    - by richever
    I've got a basic Spring Security 3 set up using my own login page. My configuration is below. I have the login and sign up page accessible to all as well as most everything else. I'm new to Spring Security and understand that if a user is trying to access a protected resource they will be taken to the defined login page. And upon successful login they are taken to some other page, home in my case. I want to keep the latter behavior; however, I'd like specify that if a user tries to access certain resources they are taken to the sign up page, not the login page. Currently, in my annotated controllers I check the security context to see if the user is logged in and if not I redirect them to the sign up page. I only do this currently with two urls and no others. This seemed redundant so I tried creating a HandlerInterceptor to redirect for these requests but realized that with annotations, you can't specify specific requests to be handled - they all are. So I'm wondering if there is some way to implement this type of specific url handling in Spring Security, or is going the HandlerInterceptor route my only option? Thanks! <http auto-config="true" use-expressions="true"> <intercept-url pattern="/login*" access="permitAll"/> <intercept-url pattern="/signup*" access="permitAll"/> <intercept-url pattern="/static/**" filters="none" /> <intercept-url pattern="/" access="permitAll"/> <form-login login-page="/login" default-target-url="/home"/> <logout logout-success-url="/home"/> <anonymous/> <remember-me/> </http>

  • Image Conversion from Bitmap to Icon doesn't seem to work

    - by contactmatt
    I have a simple function that takes a bitmap, and converts the bitmap to an ICON format. Below is the function. (I placed literal values in place of the variables) Bitmap tempBmp = new Bitmap(@"C:\temp\mypicture.jpeg"); Bitmap bmp = new Bitmap(tempBmp, 16, 16); bmp.Save("@C:\temp\mypicture2.ico", ImageFormat.Icon) It doesn't seem to be converting correctly...or so I think. After the image is converted, some browsers do not reconigze the image as a true "ICON" , and even Visual Studio 2008 doesn't reconigze the image as an icon after its converted to an Icon format. For example, I was going to set the Icon property for my Win32 form app with the Icon i just converted. I open the dialouge box and select the icon I just converted and get the following error. -- "Argument 'picture' must be a picture that can be used as a Icon." I've browsed the web and come across complicated code where people take the time to manually convert the bitmap to different formats, but I would think the above code should work, and that the .NET framework would take care of this conversion.

  • WPF designer gives exception when databinding a label to a checkbox

    - by John
    I'm sure it's something stupid, but I'm playing around with databinding. I have a checkbox and a label on a form. What I'm trying to do is simply bind the Content of the label to the checkbox's IsChecked value. What I've done runs fine (no compilation errors and acts as expected), but if I touch the label in the XAML, the designer trows an exception: System.NullReferenceException Object reference not set to an instance of an object. at MS.Internal.Designer.PropertyEditing.Editors.MarkupExtensionInlineEditorControl.BuildBindingString(Boolean modeSupported, PropertyEntry propertyEntry) at <Window x:Class="UnitTestHelper.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:FileSysCtls="clr-namespace:WPFFileSystemUserControls;assembly=WPFFileSystemUserControls" xmlns:HelperClasses="clr-namespace:UnitTestHelper" Title="MainWindow" Height="406" Width="531"> <Window.Resources> <HelperClasses:ThreestateToBinary x:Key="CheckConverter" /> </Window.Resources> <Grid Height="367" Width="509"> <CheckBox Content="Step into subfolders" Height="16" HorizontalAlignment="Left" Margin="17,254,0,0" Name="chkSubfolders" VerticalAlignment="Top" Width="130" IsThreeState="False" /> <Label Height="28" HorizontalAlignment="Left" Margin="376,254,0,0" Name="lblStepResult" VerticalAlignment="Top" Width="120" IsEnabled="True" Content="{Binding IsChecked, ElementName=chkSubfolders, Mode=OneWay, UpdateSourceTrigger=PropertyChanged, Converter={StaticResource CheckConverter}}" /> </Grid> The ThreeStateToBinary class is as follows: class ThreestateToBinary : IValueConverter { #region IValueConverter Members public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { if ((bool)value) return "Checked"; else return "Not checked"; //throw new NotImplementedException(); } public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { return ((string)value == "Checked"); //throw new NotImplementedException(); } #endregion } Quite honestly, I'm playing around with it at this point. It was originally simpler (not using the ValueConverter) but was displaying similar behavior when I simply had the content set to: Content="{Binding IsChecked, ElementName=chkSubfolders, UpdateSourceTrigger=PropertyChanged}" Any ideas? Thanks, John

  • How to change the Struts2 validation error message in the case of an invalid field value?

    - by FarmBoy
    I'm using Struts2 validation on a web form. In the case that a field is suppose to be an integer or Date, the <s:fielderror> message I receive is a generic Invalid field value for field "[fieldname]" Naturally, I want to customize this for the user. Here's an example validation: <field name="spouseDOB"> <field-validator type="date"> <message>"Spouse Date of Birth" is invalid.</message> </field-validator> <field-validator type="date"> <param name="min">01/01/1900</param> <message>"Spouse Date of Birth" must be after 1900 AD. </field-validator> </field> The message "Spouse Date of Birth" is invalid. never appears, for any invalid date that I have tried. The output is the generic Invalid field value for field spouseDOB spouseDOB is a java.util.Date object in the action class. It is set by a <s:textfield> in the JSP.

  • Debugger Visualizer, ElementHost, and Edit and Continue problems

    - by Frank Fella
    I recently wrote a custom Debugger Visualizer for Visual Studio 2008 for one of the custom types in my application. The UI for the visualizer is written in WPF and is hosted in an element host and shown using the IDialogVisualizerService windowService object. Everything works great, and my visualizer loads and shows the relevant information, but if try to "edit and continue" in my application after loading the visualizer, Visual Studio crashes with no useful error message. In trying to debug this I removed almost all of my code from the solution to the point where I was only serializing a string with the ObjectSource and displaying just an empty element host and I still get the crash on edit and continue. If I remove the element host and show a WinForms control or form there is no crash. Here is the Visualizer code: using System; using System.Drawing; using System.IO; using System.Runtime.Serialization.Formatters.Binary; using System.Windows.Forms; using System.Windows.Forms.Integration; using Microsoft.VisualStudio.DebuggerVisualizers; using ObjectVisualizerShared; using ObjectVisualizerUI; namespace ObjectVisualizer { public class Visualizer : DialogDebuggerVisualizer { protected override void Show(IDialogVisualizerService windowService, IVisualizerObjectProvider objectProvider) { try { Stream stream = objectProvider.GetData(); if (stream.Length > 0) { BinaryFormatter formatter = new BinaryFormatter(); VisualizerNode node = (VisualizerNode)formatter.Deserialize(stream); if (node != null) { VisualizerWindow window = new VisualizerWindow(node); ElementHost host = new ElementHost(); host.Child = window; host.Dock = DockStyle.Fill; host.Size = new Size(800, 600); windowService.ShowDialog(host); } } } catch (Exception ex) { MessageBox.Show(string.Format("Error!\n{0}", ex), "Object Visualizer"); } } } } Any ideas?

  • Using Hibernate's ScrollableResults to slowly read 90 million records

    - by at
    I simply need to read each row in a table in my MySQL database using Hibernate and write a file based on it. But there are 90 million rows and they are pretty big. So it seemed like the following would be appropriate: ScrollableResults results = session.createQuery("SELECT person FROM Person person") .setReadOnly(true).setCacheable(false).scroll(ScrollMode.FORWARD_ONLY); while (results.next()) storeInFile(results.get()[0]); The problem is the above will try and load all 90 million rows into RAM before moving on to the while loop... and that will kill my memory with OutOfMemoryError: Java heap space exceptions :(. So I guess ScrollableResults isn't what I was looking for? What is the proper way to handle this? I don't mind if this while loop takes days (well I'd love it to not). I guess the only other way to handle this is to use setFirstResult and setMaxResults to iterate through the results and just use regular Hibernate results instead of ScrollableResults. That feels like it will be inefficient though and will start taking a ridiculously long time when I'm calling setFirstResult on the 89 millionth row... UPDATE: setFirstResult/setMaxResults doesn't work, it turns out to take an unusably long time to get to the offsets like I feared. There must be a solution here! Isn't this a pretty standard procedure?? I'm willing to forgo Hibernate and use JDBC or whatever it takes. UPDATE 2: the solution I've come up with which works ok, not great, is basically of the form: select * from person where id > <offset> and <other_conditions> limit 1 Since I have other conditions, even all in an index, it's still not as fast as I'd like it to be... so still open for other suggestions..

  • MySQL performance

    - by kapil.israni
    Hi, I have this LAMP application with about 900k rows in MySQL and I am having some performance issues. Background - Apart from the LAMP stack , there's also a Java process (multi-threaded) that runs in its own JVM. So together with LAMP & java, they form the complete solution. The java process is responsible for inserts/updates and few selects as well. These inserts/updates are usually in bulk/batch, anywhere between 5-150 rows. The PHP front-end code only does SELECT's. Issue - the PHP/SELECT queries become very slow when the java process is running. When the java process is stopped, SELECT's perform alright. I mean the performance difference is huge. When the java process is running, any action performed on the php front-end results in 80% and more CPU usage for mysqld process. Any help would be appreciated. MySQL is running with default parameters & settings. Software stack - Apache - 2.2.x MySQL -5.1.37-1ubuntu5 PHP - 5.2.10 Java - 1.6.0_15 OS - Ubuntu 9.10 (karmic)

  • SQL 2000 (MSDE) Hangs When It Receives an Erroneous Query from a Classic ASP Web Application

    - by Jimbo
    I have a SQL interface page in my classic ASP web app that allows admin users to run queries against the app's database (MSDE 2000) - it simply consists of a textarea that the user submits and the app returns the resulting list of records as below Dim oRS Set oRS = Server.CreateObject("ADODB.Recordset") oRS.ActiveConnection = sConnectionString // run the query - this is for the admin only so doesnt check for sql safe commands etc. oRS.Open Request.Form("txtSQL") If Not oRS.EOF Then // list the field names from the recordset For i = 0 to oRS.Fields.Count - 1 Response.Write oRS.Fields(i).name & "&nbsp;" Next // show the data for each record in the recordset While Not oRS.EOF For i = 0 to oRS.Fields.Count - 1 Response.Write oRS.Fields(i).value & "&nbsp;" Next Response.Write "<br />" oRS.Movenext() Wend End If The problem with this is that if you send it an invalid query (with a spelling mistake, invalid join etc.) instead of throwing back an error immediately, it hangs IIS (you can see this by trying to browse the app from another computer, it fails) for a number of minutes and THEN returns the error. I have NO idea why! Can anyone help?
