  • jQuery $(document).ready and UpdatePanels?

    - by Herb Caudill
    I'm using jQuery to wire up some mouseover effects on elements that are inside an UpdatePanel. The events are bound in $(document).ready . For example: $(function() { $('div._Foo').bind("mouseover", function(e) { // Do something exciting }); }); Of course, this works fine the first time the page is loaded, but when the UpdatePanel does a partial page update, it's not run and the mouseover effects don't work any more inside the UpdatePanel. What's the recommended approach for wiring stuff up in jQuery not only on the first page load, but every time an UpdatePanel fires a partial page update? Should I be using the ASP.NET ajax lifecycle instead of $(document).ready?

  • What's an elegant solution to get the property values from two classes (that have the same property

    - by SlipToFall
    Essentially I have to deal with a poorly implemented web service. They have two classes that don't derive from a parent class, but have the same properties (Ughh...). So it looks like this in my web service proxy class file: public partial class Product1 { public int Quantity; public int Price; } public partial class Product2 { public int Quantity; public int Price; } So what's the best way to grab the values from known properties without duplicating the code and casting to their respective classes? I know I probably could use reflection, but that can get ugly. If there is an easier less crazier way to do it (maybe in the new c# features?) please let me know.

  • Getting every nth Element of a Sequence

    - by Alexander Rautenberg
    I am looking for a way to create a sequence consisting of every nth element of another sequence, but don't seem to find a way to do that in an elegant way. I can of course hack something, but I wonder if there is a library function that I'm not seeing. The sequence functions whose names end in -i seem to be quite good for the purpose of figuring out when an element is the nth one or (multiple of n)th one, but I can only see iteri and mapi, none of which really lends itself to the task. Example: let someseq = [1;2;3;4;5;6] let partial = Seq.magicfunction 3 someseq Then partial should be [3;6]. Is there anything like it out there? Edit: If I am not quite as ambitious and allow for the n to be constant/known, then I've just found that the following should work: let rec thirds lst = match lst with | (_,_,x)::t -> x::thirds t | _ -> [] Would there be a way to write this shorter?

  • How to Execute Base Class's Method Before Implementors's Method?

    - by DaveDev
    I have the following page public partial class GenericOfflineCommentary : OfflineFactsheetBase { } where OfflineFactsheetBase is defined as public class OfflineFactsheetBase : System.Web.UI.Page { public OfflineFactsheetBase() { this.Load += new EventHandler(this.Page_Load); this.PreInit += new EventHandler(this.Page_PreInit); } protected void Page_PreInit(object sender, EventArgs e) { if (Request.QueryString["data"] != null) { this.PageData = StringCompressor.DecompressString(Request.QueryString["data"]); this.ExtractPageData(); } } } OfflineFactsheetBase has the following virtual method: public virtual void ExtractPageData() { // get stuff relevant to all pages that impmement OfflineFactsheetBase } which is implemented in all pages that impmement OfflineFactsheetBase as follows: public partial class GenericOfflineCommentary : OfflineFactsheetBase { public override void ExtractPageData() { // get stuff relevant to an OfflineCommentary page. } } Currently, only GenericOfflineCommentary's ExtractPageData() is firing. How can I modify this to first run OfflineFactsheetBase's ExtractPageData() and then GenericOfflineCommentary's? edit: I'm trying to avoid having to call base.ExtractPageData() in every implementor. Is this possible?

  • DropDownList always does full-page postback, the first time it fires.

    - by CodexArcanum
    I have an ASP.NET page using the AJAX library. There is a dropdownlist inside an UpdatePanel, which on index changing is supposed to update a different UpdatePanel to modify a grid control. But after the page first comes up, and you adjust the ddl, the entire page postbacks, followed by a (correct) partial postback. After this one time, every other usage of the ddl performs correctly, trigger partial postbacks. Both the panel and the ddl are being added from code. The UP is Conditional updates and ChildrenAsTriggers = true. The dropdownlist is AutoPostBack true and has an event set up on SelectedIndexChanged. So what is going on? I've tried adjusting every setting I can think of and still the page completely refreshes once, then works fine after that.

  • How do I pass objects through a _url based on a routing in rails?

    - by Angela
    I want to pass the attributes associated with two objects into a path created from a route. In this case, the _url is skip_contact_letter_url. contact_letter and letter are passed through a render partial. The clip below resides in the partial. <%= link_to_remote "Skip Letter Remote #{contact_letter}", :url => skip_contact_letter_url(contact_letter, letter), :update => "update-area-#{contact_letter.id}-#{letter.id}" %> <span id='update-area-<%="#{contact_letter.id}-#{letter.id}"%>'> </span> The route I created looks like this: map.resources :contact_letters, :member => {:skip => :post} And the controller looks like this: def skip @contact_letter = ContactLetter.new(params[:all]) @contact_letter.status = "skipped" @contact_letter.date_sent = Date.today #@contact_letter.date_created = Date.today if @contact_letter.save render :text => 'This letter was skipped!' end end When I look at the console, none of the parameters from contact_letter or letter get passed through.

    - by neiled
    class Person belongs_to :team class Status #has last_updated property class Team has_many :members, :class => "Person" Ok, so I have a Team class which has many People in it and each of those people has a status and each status has a last_updated property. I'm currently rendering a partial with a collection similar to: =render :partial => "user", :collection => current_user.team.members Now how do I go about sorting the collection by the last_updated property of the Status class? Thanks in advance! p.s. I've just written the ruby code from memory, it's just an example, it's not meant to compile but I hope you get the idea!

Thank you for the help so far :) Edit 3 So it turns out that installing the ca-certificates package didn't install the one that I needed. I found this post about certificates being presented out of order. This seems to be the case with my request to sagepay. The solution ended up being to install another CA certificate from Verisign. I'm not sure why this fixes the issue with it being out of order but it does, but I suspect the out of order issue really isn't a problem at all and it was infact because I was missing a certificate all along. The additional certificate is available in that post but I didn't want to blindly trust it. I've looked at the list of CA certificates from cURL's site and it is listed there so I do trust it.

  • How to delete files and folders that cannot be deleted?

    - by glenneroo
    I have a backup copy of a previous Windows' Documents and Settings folder which only contains my original user and within 2 more directories: Favorites and Local Settings. When I try to delete Local Settings I get this error: When I try to delete Favorites, I get this error: I ran this in a cmd shell: attrib *.* -r -a -s -h /s ...but it did not help, nor did it return any errors/warnings. I used Unlocker v1.8.5 and LockHunter repeatedly at multiple levels to see if any files are in use, but both always say: No Files Locked. Update #1: I was able to rename the directory, which now gives me this warning before (trying to) delete: If I press Yes (or Yes to All) then I get this error: Update #2: I let chkdsk /f run which required a reboot since it's on my primary system partition. During Stage 2 scanning, I received about 40 of these: Deleting an index entry from index $0 of file 25. ...followed by: Deleting index entry cookies in index $I30 of file 37576. ...but I still get the first error dialog above when trying to delete. I ran chkdsk again, this time: chkdsk /f /r. Produced no messages. Same result when deleting. Update #3: Digging deeper, the 99 is the name of one of many directories located deep in here: C:\Documents and Settings.OLD\User\Local Settings\Application Data\Microsoft\Messenger\[email protected]\SharingMetadata\[email protected]\DFSR\Staging\CS{D4E4AE55-B5E2-F03B-5189-6C4DA6E41788}\ Inside each of those directories were files with names such as: 2300-{C93D01AC-0739-4FD9-88C7-13D2F21A208E}-v2300-{C93D01AC-0739-4FD9-88C7-13D2F21A208E}-v2300-Downloaded.frx I noticed that, unlike all the directories, I couldn't rename any of these files. I also noticed that the file + dir names were extremely long: Original directory = 194 characters Filenames = 100+ characters Together the length exceeds the 255-char limit which is bad and would explain the error message I posted in Update #1. Partial Solution: Rename all directories until the total path length is less than 100. Afterwards I was able to rename the .frx files, not to mention delete everything inside the Local Settings directory. This is only a partial solution because these (empty) directories are still not deleteable, C:\1\2\Favorites\Wien\What To Do.. C:\1\2\Favorites\Photography\FIRE Same error as above: Here is what Explorer properties shows for both folders: Update #4 (another partial solution): Using harrymc's answer combined with thoroughly reading through this amazing MS-KB article which contains nearly everyone's idea and then some, inconspicuously titled: You cannot delete a file or a folder on an NTFS file system volume. I was able to delete the 2nd folder C:\1\2\Favorites\Photography\FIRE - the problem being that there was an invisible trailing space at the end. I got lucky when I did an auto-complete whilst playing around with the del "\\?\<path>" command which he suggested. NOTE: A normal del did NOT work, nor did deleting from explorer. Now all that is left is the first directory C:\1\2\Favorites\Wien\What To Do.. (yes I tried endlessly with multiple combinations of the above solution ;) Keep 'em coming! =)

  • Ajax Control Toolkit July 2011 Release and the New HTML Editor Extender

    - by Stephen Walther
    I’m happy to announce the July 2011 release of the Ajax Control Toolkit which includes important bug fixes and a completely new HTML Editor Extender control. You can download the July 2011 Release by visiting the Ajax Control Toolkit CodePlex site at: http://AjaxControlToolkit.CodePlex.com Using the New HTML Editor Extender Control You can use the new HTML Editor Extender to extend any standard ASP.NET TextBox control so that it supports rich formatting such as bold, italics, bulleted lists, numbered lists, typefaces and different foreground and background colors. The following code illustrates how you can extend a standard ASP.NET TextBox control with the HtmlEditorExtender: <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Simple.aspx.cs" Inherits="WebApplication1.Simple" %> <%@ Register TagPrefix="asp" Namespace="AjaxControlToolkit" Assembly="AjaxControlToolkit" %> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>Simple</title> </head> <body> <form id="form1" runat="server"> <asp:ToolkitScriptManager runat="Server" /> <asp:TextBox ID="txtComments" TextMode="MultiLine" Columns="60" Rows="8" runat="server" /> <asp:HtmlEditorExtender TargetControlID="txtComments" runat="server" /> </form> </body> </html> This page has the following three controls: ToolkitScriptManager – The ToolkitScriptManager renders all of the scripts required by the Ajax Control Toolkit. TextBox – The TextBox control is a standard ASP.NET TextBox which is set to display multiple lines (a TextArea instead of an Input element). HtmlEditorExtender – The HtmlEditorExtender is set to extend the TextBox control. You can use the standard TextBox Text property to read the rich text entered into the TextBox control on the server. Lightweight and HTML5 The HTML Editor Extender works on all modern browsers including the most recent versions of Mozilla Firefox (Firefox 5), Google Chrome (Chrome 12), and Apple Safari (Safari 5). Furthermore, the HTML Editor Extender is compatible with Microsoft Internet Explorer 6 and newer. The HTML Editor Extender is very lightweight. It takes advantage of the HTML5 ContentEditable attribute so it does not require an iframe or complex browser workarounds. If you select View Source in your browser while using the HTML Editor Extender, we hope that you will be pleasantly surprised by how little markup and script is generated by the HTML Editor Extender. Customizable Toolbar Buttons Depending on the web application that you are building, you will want to display different toolbar buttons with the HTML Editor Extender. One of the design goals of the HTML Editor Extender was to make it very easy for you to customize the toolbar buttons. Imagine, for example, that you want to use the HTML Editor Extender when accepting comments on blog posts. In that case, you might want to restrict the type of formatting that a user can display. You might want to enable a user to format text as bold or italic but you do not want the user to make any other formatting changes. The following page illustrates how you can customize the HTML Editor Extender toolbar: <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="CustomToolbar.aspx.cs" Inherits="WebApplication1.CustomToolbar" %> <%@ Register TagPrefix="asp" Namespace="AjaxControlToolkit" Assembly="AjaxControlToolkit" %> <html> <head runat="server"> <title>Custom Toolbar</title> </head> <body> <form id="form1" runat="server"> <asp:ToolkitScriptManager Runat="server" /> <asp:TextBox ID="txtComments" TextMode="MultiLine" Columns="50" Rows="10" Text="Hello <b>world!</b>" Runat="server" /> <asp:HtmlEditorExtender TargetControlID="txtComments" runat="server"> <Toolbar> <asp:Bold /> <asp:Italic /> </Toolbar> </asp:HtmlEditorExtender> </form> </body> </html> Notice that the HTML Editor Extender in the page above has a Toolbar subtag. You can list the toolbar buttons which you want to appear within the subtag. In the case above, only Bold and Italic buttons are displayed. Here is a complete list of the Toolbar buttons currently supported by the HTML Editor Extender: Undo Redo Bold Italic Underline StrikeThrough Subscript Superscript JustifyLeft JustifyCenter JustifyRight JustifyFull InsertOrderedList InsertUnorderedList CreateLink UnLink RemoveFormat SelectAll UnSelect Delete Cut Copy Paste BackgroundColorSelector ForeColorSelector FontNameSelector FontSizeSelector Indent Outdent InsertHorizontalRule HorizontalSeparator Of course the HTML Editor Extender was designed to be extensible. You can create your own buttons and add them to the control. Compatible with the AntiXSS Library When using the HTML Editor Extender on a public facing website, we strongly recommend that you use the HTML Editor Extender with the AntiXSS Library. If you allow users to submit arbitrary HTML, and you don’t take any action to strip out malicious markup, then you are opening your website to Cross-Site Scripting Attacks (XSS attacks). The HTML Editor Extender uses the Provider Model to support different Sanitizer Providers. The July 2011 release of the Ajax Control Toolkit ships with a single Sanitizer Provider which uses the AntiXSS library (see http://AntiXss.CodePlex.com ). A Sanitizer Provider is responsible for sanitizing HTML markup by removing any malicious elements, attributes, and attribute values. For example, the AntiXss Sanitizer Provider will take the following block of HTML: <b><a href=""javascript:doEvil()"">Visit Grandma</a></b> <script>doEvil()</script> And return the following sanitized block of HTML: <b><a href="">Visit Grandma</a></b> Notice that the JavaScript href and <SCRIPT> tag are both stripped out. Be aware that there are a depressingly large number of ways to sneak evil markup into your HTML. You definitely want a Sanitizer as a safety net. Before you can use the AntiXSS Sanitizer Provider, you must add three assemblies to your web application: AntiXSSLibrary.dll, HtmlSanitizationLibrary.dll, and SanitizerProviders.dll. All three assemblies are included with the CodePlex download of the Ajax Control Toolkit in the SanitizerProviders folder. Here’s how you modify your web.config file to use the AntiXSS Sanitizer Provider: <configuration> <configSections> <sectionGroup name="system.web"> <section name="sanitizer" requirePermission="false" type="AjaxControlToolkit.Sanitizer.ProviderSanitizerSection, AjaxControlToolkit"/> </sectionGroup> </configSections> <system.web> <compilation targetFramework="4.0" debug="true"/> <sanitizer defaultProvider="AntiXssSanitizerProvider"> <providers> <add name="AntiXssSanitizerProvider" type="AjaxControlToolkit.Sanitizer.AntiXssSanitizerProvider"></add> </providers> </sanitizer> </system.web> </configuration> You can detect whether the HTML Editor Extender is using the AntiXSS Sanitizer Provider by checking the HtmlEditorExtender SanitizerProvider property like this: if (MyHtmlEditorExtender.SanitizerProvider == null) { throw new Exception("Please enable the AntiXss Sanitizer!"); } When the SanitizerProvider property has the value null, you know that a Sanitizer Provider has not been configured in the web.config file. Because the AntiXSS library requires Full Trust, you cannot use the AntiXSS Sanitizer Provider with most shared website hosting providers. Because most shared hosting providers only support Medium Trust and not Full Trust, we do not recommend using the HTML Editor Extender with a public website hosted with a shared hosting provider. Why a New HTML Editor Control? The Ajax Control Toolkit now includes two HTML Editor controls. Why did we introduce a new HTML Editor control when there was already an existing HTML Editor? We think you will like the new HTML Editor much more than the previous one. We had several goals with the new HTML Editor Extender: Lightweight – We wanted to leverage HTML5 to create a lightweight HTML Editor. The new HTML Editor generates much less markup and script than the previous HTML Editor. Secure – We wanted to make it easy to integrate the AntiXSS library with the HTML Editor. If you are creating a public facing website, we strongly recommend that you use the AntiXSS Provider. Customizable – We wanted to make it easy for users to customize the toolbar buttons displayed by the HTML Editor. Compatibility – We wanted to ensure that the HTML Editor will work with the latest versions of the most popular browsers (including Internet Explorer 6 and higher). The old HTML Editor control is still included in the Ajax Control Toolkit and continues to live in the AjaxControlToolkit.HTMLEditor namespace. We have not modified the control and you can continue to use the control in the same way as you have used it in the past. However, we hope that you will consider migrating to the new HTML Editor Extender for the reasons listed above. Summary We’ve introduced a new Ajax Control Toolkit control with this release. I want to thank the developers and testers on the Superexpert team for the huge amount of work which they put into this control. It was a non-trivial task to build an entirely new control which has the complexity of the HTML Editor in less than 6 weeks. Please let us know what you think! We want to hear your feedback. If you discover issues with the new HTML Editor Extender control, or you have questions about the control, or you have ideas for how it can be improved, then please post them to this blog. Tomorrow starts a new sprint

  • Messing with the Team

    - by Robert May
    Good Product Owners will help the team be the best that they can be.  Bad product owners will mess with the team and won’t care about the team.  If you’re a product owner, seek to do good and avoid bad behavior at all costs.  Remember, this is for YOUR benefit and you have much power given to you.  Use that power wisely. Scope Creep The product owner has several tools at his disposal to inject scope into an iteration.  First, the product owner can use defects to inject scope.  To do this, they’ll tell the team what functionality that they want to see in a feature.  Then, after the feature is developed, the Product Owner will decide that they don’t really like how the functionality behaves.  To change it, rather than creating a new story, they’ll add a defect.  The functionality is correct, as designed, but the Product Owner doesn’t like it.  By creating the defect, the Product Owner destroys the trust that the team has of the product owner.  They may not be able to count the story, because the Product Owner changed the story in the iteration, and the team then ends up looking like they have low velocity for something over which they have no control.  This is bad.  One way to deal with this is to add “Product Owner Time” to the iteration.  This will slow the velocity, but then the ScrumMaster can tell stake holders that this time is strictly in place to deal with bad behavior of the Product Owner. Another mechanism often used to inject Scope is the concept of directed development.  Outside of planning, stand-ups, or any other meeting, the Product Owner will take a developer aside and ask them to complete a task for them.  This is bad!  The team should be allocating all of their time to development.  If the Product Owner asks for a favor, then time that would normally be used for development will be used for a pet project of the Product Owner and the team will not get credit for this work.  Selfish product owners do this, and I typically see people who were “managers” do this behavior.  Authoritarian command and control development environments also see this happen.  The best thing that can happen is for the team member to report the issue to the ScrumMaster and the ScrumMaster to get very aggressive with management and the Product Owner to try and stop the behavior.  This may result in the ScrumMaster being fired, but if the behavior continues, Scrum is doomed.  This problem is especially bad in cases where the team member’s direct supervisor is the Product Owner.  I don’t recommend that the Product Owner or ScrumMaster have a direct report relationship with team members, since team members need the ability to say no.  To work around this issue, team members need to say no.  If that fails, team members need to add extra time to the iteration to deal with the scope creep injection and accept the lower velocity. As discussed above, another mechanism for injecting scope is by changing acceptance tests after the work is complete.  This is similar to adding defects to change scope and is bad.  To get around, add time for Product Owner uncertainty to the iteration and make sure that stakeholders are aware of the need to add this time because of the Product Owner. Refusing to Prioritize Refusing to prioritize causes chaos for the team.  From the team’s perspective, things that are not important will be worked on while things that the team knows are vital will be ignored.  A poor Product Owner will often pick the stories for the iteration on a whim.  This leads to the team working on many different aspects of the product and results in a lower velocity, since each iteration the team must switch context to the new area of development. The team will also experience confusion about priorities.  In one iteration, Feature X was the highest priority and had to be done.  Then, the following iteration, even though parts of Feature X still need to be completed, no stories to address them will be in the iteration.  However, three iterations later, Feature X will again become high priority. This will cause the team to not trust the Product Owner, and eventually, they’ll stop caring about the features they implement.  They won’t know what is important, so to insulate themselves from the ever changing chaos, they’ll become apathetic to all features.  Team members are some of the most creative people in a company.  By losing their engagement, the company is going to have a substandard product because the passion for the product won’t be in the team. Other signs that the Product Owner refuses to prioritize is that no one outside of the product owner will be consulted on priorities.  Additionally, the product, release, and iteration backlogs will be weak or non-existent. Dealing with this issue is not easy.  This really isn’t something the team can fix, short of taking over the role of Product Owner themselves.  An appeal to the stake holders might work, but only if the Product Owner isn’t a “manager” themselves.  The ScrumMaster needs to protect the team and do what they can to either get the Product Owner to prioritize or have the Product Owner replaced. Managing the Team A Product Owner that is also the “boss” of team members is a Scrum team that is waiting to fail.  If your boss tells you to do something, failing to do that something can cause you to be fired.  The team needs the ability to tell the Product Owner NO.  If the product owner introduces scope creep, the team has a responsibility to tell the Product Owner no.  If the Product Owner tries to get the team to commit to more than they can accomplish in an iteration, the team needs the ability to tell the Product Owner no. If the Product Owner is your boss and determines your pay increases, you’re probably not going to ever tell them no, and Scrum will likely fail.  The team can’t do much in this situation. Another aspect of “managing the team” that often happens is the Product Owner tries to tell the team how to develop the stories that are in the iteration.  This is one reason why I recommend that Product Owners are NOT technical people.  That way, the team can come up with the tasks that are needed to accomplish the stories and the Product Owner won’t know better.  If the Product Owner is technical, the ScrumMaster will need to take great care to protect the team from the ScrumMaster changing how the team thinks they need to implement the stories. Product Owners can also try to manage the team by their body language.  If the team says a task is going to take 6 hours to complete, and the Product Owner disagrees, they will use some kind of sour body language to indicate this disagreement.  In weak teams, this may cause the team to revise their estimate down, which will result in them taking longer than estimated and may result in them missing the iteration.  The ScrumMaster will need to make sure that the Product Owner doesn’t send such messages and that the team ignores them and estimates what they REALLY think it will take to complete the tasks.  Forcing the team to deal with such items in the retrospective can be helpful. Absenteeism The team is completely dependent upon the Product Owner to develop features for the customer.  The Product Owner IS the voice of the customer and without them, the team will lack direction.  Being the Product Owner is a full time job!  If the Product Owner cannot dedicate daily time with the team, a different product owner should be found. The Product Owner needs to attend every stand-up, planning meeting, showcase, and retrospective that the team has.  The team also must be able to have instant communication with the product owner.  They must not be required to schedule meetings to speak with their product owner.  The team must be the highest priority task that the Product Owner has. The best way to work around an absent Product Owner is to appoint a new Product Owner in the team.  This person will be responsible for making the decisions that the Product Owner should be making and to act as the liaison to the absent Product Owner.  If the delegate Product Owner doesn’t have authority to make decisions for the team, Scrum will fail.  If the Product Owner is absent, the ScrumMaster should seek to have that Product Owner replaced by someone who has the time and ability to be a real Product Owner. Making it Personal Too often Product Owners will become convinced that their ideas are the ones that matter and that anyone who disagrees is making a personal attack on them.  Remember that Product Owners will inherently be at odds with many people, simply because they have the need to prioritize.  Others will frequently question prioritization because they only see part of the picture that Product Owners face. Product Owners must have a thick skin and think egos.  If they don’t, they tend to make things personal, which causes them to become emotional and causes them to take actions that can destroy the trust that team members have in the Product Owner. If a Product Owner is making things person, the best thing that team members can do is reassure them that its not personal, but be firm about doing what is best for the Company and for the users.  The ScrumMaster should also spend significant time coaching the Product Owner on how to not react emotionally and how to accept criticism without becoming defensive. Conclusion I’m sure there are other ways that a Product Owner can mess with the team, but these are the most common that I’ve seen.  I would encourage all Product Owners to seek to be a good Product Owner.  If you find yourself behaving in any of the bad product owner ways, change your behavior today!  Your team will thank you. Remember, being Product Owner is very difficult!  Product Owner is one of the most difficult roles in Scrum.  However, it can also be one of the most rewarding roles in Scrum, since Product Owners literally see their ideas brought to life on the computer screen.  Product Owners need to be very patient, even in the face of criticism and need to be willing to make tough decisions on priority, but then not become offended when others disagree with those decisions.  Companies should spend the time needed to find the right product owners for their teams.  Doing so will only help the company to write better software.

  • Peer did not return a certificate

    - by pfista
    I am trying to get two way SSL authentication working between a Python server and an Android client application. I have access to both the server and client, and would like to implement client authentication using my own certificate. So far I have been able to verify the server certificate and connect without client authentication. What sort of certificate does the client need and how do I get it to automatically send it to the server during the handshake process? Here is the client and server side code that I have so far. Is my approach wrong? Server Code while True: # Keep listening for clients c, fromaddr = sock.accept() ssl_sock = ssl.wrap_socket(c, keyfile = "serverPrivateKey.pem", certfile = "servercert.pem", server_side = True, # Require the client to provide a certificate cert_reqs = ssl.CERT_REQUIRED, ssl_version = ssl.PROTOCOL_TLSv1, ca_certs = "clientcert.pem", #TODO must point to a file of CA certificates?? do_handshake_on_connect = True, ciphers="!NULL:!EXPORT:AES256-SHA") print ssl_sock.cipher() thrd = sock_thread(ssl_sock) thrd.daemon = True thrd.start() I suspect I may be using the wrong file for ca_certs...? Client Code private boolean connect() { try { KeyStore keystore = KeyStore.getInstance("BKS"); // Stores the client certificate, to be sent to server KeyStore truststore = KeyStore.getInstance("BKS"); // Stores the server certificate we want to trust // TODO: change hard coded password... THIS IS REAL BAD MKAY truststore.load(mSocketService.getResources().openRawResource(R.raw.truststore), "test".toCharArray()); keystore.load(mSocketService.getResources().openRawResource(R.raw.keystore), "test".toCharArray()); // Use the key manager for client authentication. Keys in the key manager will be sent to the host KeyManagerFactory keyFManager = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm()); keyFManager.init(keystore, "test".toCharArray()); // Use the trust manager to determine if the host I am connecting to is a trusted host TrustManagerFactory trustMFactory = TrustManagerFactory.getInstance(TrustManagerFactory .getDefaultAlgorithm()); trustMFactory.init(truststore); // Create the socket factory and add both the trust manager and key manager SSLCertificateSocketFactory socketFactory = (SSLCertificateSocketFactory) SSLCertificateSocketFactory .getDefault(5000, new SSLSessionCache(mSocketService)); socketFactory.setTrustManagers(trustMFactory.getTrustManagers()); socketFactory.setKeyManagers(keyFManager.getKeyManagers()); // Open SSL socket directly to host, host name verification is NOT performed here due to // SSLCertificateFactory implementation mSSLSocket = (SSLSocket) socketFactory.createSocket(mHostname, mPort); mSSLSocket.setSoTimeout(TIMEOUT); // Most SSLSocketFactory implementations do not verify the server's identity, allowing man-in-the-middle // attacks. This implementation (SSLCertificateSocketFactory) does check the server's certificate hostname, // but only for createSocket variants that specify a hostname. When using methods that use InetAddress or // which return an unconnected socket, you MUST verify the server's identity yourself to ensure a secure // connection. verifyHostname(); // Safe to proceed with socket now ... I have generated a client private key, a client certificate, a server private key, and a server certificate using openssl. I then added the client certificate to keystore.bks (which I store in /res/raw/keystore.bks) I then added the server certificate to the truststore.bks So now when the client tries to connect I am getting this error server side: ssl.SSLError: [Errno 1] _ssl.c:504: error:140890C7:SSL routines:SSL3_GET_CLIENT_CERTIFICATE:peer did not return a certificate And when I try to do this in the android client SSLSession s = mSSLSocket.getSession(); s.getPeerCertificates(); I get this error: javax.net.ssl.SSLPeerUnverifiedException: No peer certificate So obviously the keystore I am using doesn't appear to have a correct peer certificate in it and thus isn't sending one to the server. What should I put in the keystore to prevent this exception? Furthermore, is this method of two way SSL authentication safe and effective?

  • Introducing the Earthquake Locator – A Bing Maps Silverlight Application, part 1

    - by Bobby Diaz
    Update: Live demo and source code now available!  The recent wave of earthquakes (no pun intended) being reported in the news got me wondering about the frequency and severity of earthquakes around the world. Since I’ve been doing a lot of Silverlight development lately, I decided to scratch my curiosity with a nice little Bing Maps application that will show the location and relative strength of recent seismic activity. Here is a list of technologies this application will utilize, so be sure to have everything downloaded and installed if you plan on following along. Silverlight 3 WCF RIA Services Bing Maps Silverlight Control * Managed Extensibility Framework (optional) MVVM Light Toolkit (optional) log4net (optional) * If you are new to Bing Maps or have not signed up for a Developer Account, you will need to visit www.bingmapsportal.com to request a Bing Maps key for your application. Getting Started We start out by creating a new Silverlight Application called EarthquakeLocator and specify that we want to automatically create the Web Application Project with RIA Services enabled. I cleaned up the web app by removing the Default.aspx and EarthquakeLocatorTestPage.html. Then I renamed the EarthquakeLocatorTestPage.aspx to Default.aspx and set it as my start page. I also set the development server to use a specific port, as shown below. RIA Services Next, I created a Services folder in the EarthquakeLocator.Web project and added a new Domain Service Class called EarthquakeService.cs. This is the RIA Services Domain Service that will provide earthquake data for our client application. I am not using LINQ to SQL or Entity Framework, so I will use the <empty domain service class> option. We will be pulling data from an external Atom feed, but this example could just as easily pull data from a database or another web service. This is an important distinction to point out because each scenario I just mentioned could potentially use a different Domain Service base class (i.e. LinqToSqlDomainService<TDataContext>). Now we can start adding Query methods to our EarthquakeService that pull data from the USGS web site. Here is the complete code for our service class: using System; using System.Collections.Generic; using System.IO; using System.Linq; using System.ServiceModel.Syndication; using System.Web.DomainServices; using System.Web.Ria; using System.Xml; using log4net; using EarthquakeLocator.Web.Model;   namespace EarthquakeLocator.Web.Services {     /// <summary>     /// Provides earthquake data to client applications.     /// </summary>     [EnableClientAccess()]     public class EarthquakeService : DomainService     {         private static readonly ILog log = LogManager.GetLogger(typeof(EarthquakeService));           // USGS Data Feeds: http://earthquake.usgs.gov/earthquakes/catalogs/         private const string FeedForPreviousDay =             "http://earthquake.usgs.gov/earthquakes/catalogs/1day-M2.5.xml";         private const string FeedForPreviousWeek =             "http://earthquake.usgs.gov/earthquakes/catalogs/7day-M2.5.xml";           /// <summary>         /// Gets the earthquake data for the previous week.         /// </summary>         /// <returns>A queryable collection of <see cref="Earthquake"/> objects.</returns>         public IQueryable<Earthquake> GetEarthquakes()         {             var feed = GetFeed(FeedForPreviousWeek);             var list = new List<Earthquake>();               if ( feed != null )             {                 foreach ( var entry in feed.Items )                 {                     var quake = CreateEarthquake(entry);                     if ( quake != null )                     {                         list.Add(quake);                     }                 }             }               return list.AsQueryable();         }           /// <summary>         /// Creates an <see cref="Earthquake"/> object for each entry in the Atom feed.         /// </summary>         /// <param name="entry">The Atom entry.</param>         /// <returns></returns>         private Earthquake CreateEarthquake(SyndicationItem entry)         {             Earthquake quake = null;             string title = entry.Title.Text;             string summary = entry.Summary.Text;             string point = GetElementValue<String>(entry, "point");             string depth = GetElementValue<String>(entry, "elev");             string utcTime = null;             string localTime = null;             string depthDesc = null;             double?

Model I have also created a Model folder and added a new class, Earthquake.cs. The Earthquake object will hold the various properties returned from the Atom feed. Here is a sample of the code for that class. Notice the [Key] attribute on the Id property, which is required by RIA Services to uniquely identify the entity. using System; using System.Collections.Generic; using System.Linq; using System.Runtime.Serialization; using System.ComponentModel.DataAnnotations;   namespace EarthquakeLocator.Web.Model {     /// <summary>     /// Represents an earthquake occurrence and related information.     /// </summary>     [DataContract]     public class Earthquake     {         /// <summary>         /// Gets or sets the id.         /// </summary>         /// <value>The id.</value>         [Key]         [DataMember]         public string Id { get; set; }           /// <summary>         /// Gets or sets the title.         /// </summary>         /// <value>The title.</value>         [DataMember]         public string Title { get; set; }           /// <summary>         /// Gets or sets the summary.         /// </summary>         /// <value>The summary.</value>         [DataMember]         public string Summary { get; set; }           // additional properties omitted     } }   View Model The recent trend to use the MVVM pattern for WPF and Silverlight provides a great way to separate the data and behavior logic out of the user interface layer of your client applications. I have chosen to use the MVVM Light Toolkit for the Earthquake Locator, but there are other options out there if you prefer another library. That said, I went ahead and created a ViewModel folder in the Silverlight project and added a EarthquakeViewModel class that derives from ViewModelBase. Here is the code: using System; using System.Collections.ObjectModel; using System.ComponentModel.Composition; using System.ComponentModel.Composition.Hosting; using Microsoft.Maps.MapControl; using GalaSoft.MvvmLight; using EarthquakeLocator.Web.Model; using EarthquakeLocator.Web.Services;   namespace EarthquakeLocator.ViewModel {     /// <summary>     /// Provides data for views displaying earthquake information.     /// </summary>     public class EarthquakeViewModel : ViewModelBase     {         [Import]         public EarthquakeContext Context;           /// <summary>         /// Initializes a new instance of the <see cref="EarthquakeViewModel"/> class.         /// </summary>         public EarthquakeViewModel()         {             var catalog = new AssemblyCatalog(GetType().Assembly);             var container = new CompositionContainer(catalog);             container.ComposeParts(this);             Initialize();         }           /// <summary>         /// Initializes a new instance of the <see cref="EarthquakeViewModel"/> class.         /// </summary>         /// <param name="context">The context.</param>         public EarthquakeViewModel(EarthquakeContext context)         {             Context = context;             Initialize();         }           private void Initialize()         {             MapCenter = new Location(20, -170);             ZoomLevel = 2;         }           #region Private Methods           private void OnAutoLoadDataChanged()         {             LoadEarthquakes();         }           private void LoadEarthquakes()         {             var query = Context.GetEarthquakesQuery();             Context.Earthquakes.Clear();               Context.Load(query, (op) =>             {                 if ( !op.HasError )                 {                     foreach ( var item in op.Entities )                     {                         Earthquakes.Add(item);                     }                 }             }, null);         }           #endregion Private Methods           #region Properties           private bool autoLoadData;         /// <summary>         /// Gets or sets a value indicating whether to auto load data.         /// </summary>         /// <value><c>true</c> if auto loading data;

                    RaisePropertyChanged("AutoLoadData");                     OnAutoLoadDataChanged();                 }             }         }           private ObservableCollection<Earthquake> earthquakes;         /// <summary>         /// Gets the collection of earthquakes to display.         /// </summary>         /// <value>The collection of earthquakes.</value>         public ObservableCollection<Earthquake> Earthquakes         {             get             {                 if ( earthquakes == null )                 {                     earthquakes = new ObservableCollection<Earthquake>();                 }                   return earthquakes;             }         }           private Location mapCenter;         /// <summary>         /// Gets or sets the map center.         /// </summary>         /// <value>The map center.</value>         public Location MapCenter         {             get { return mapCenter; }             set             {                 if ( mapCenter != value )                 {                     mapCenter = value;                     RaisePropertyChanged("MapCenter");                 }             }         }           private double zoomLevel;         /// <summary>         /// Gets or sets the zoom level.         /// </summary>         /// <value>The zoom level.</value>         public double ZoomLevel         {             get { return zoomLevel; }             set             {                 if ( zoomLevel != value )                 {                     zoomLevel = value;                     RaisePropertyChanged("ZoomLevel");                 }             }         }           #endregion Properties     } }   The EarthquakeViewModel class contains all of the properties that will be bound to by the various controls in our views. Be sure to read through the LoadEarthquakes() method, which handles calling the GetEarthquakes() method in our EarthquakeService via the EarthquakeContext proxy, and also transfers the loaded entities into the view model’s Earthquakes collection. Another thing to notice is what’s going on in the default constructor. I chose to use the Managed Extensibility Framework (MEF) for my composition needs, but you can use any dependency injection library or none at all. To allow the EarthquakeContext class to be discoverable by MEF, I added the following partial class so that I could supply the appropriate [Export] attribute: using System; using System.ComponentModel.Composition;   namespace EarthquakeLocator.Web.Services {     /// <summary>     /// The client side proxy for the EarthquakeService class.     /// </summary>     [Export]     public partial class EarthquakeContext     {     } }   One last piece I wanted to point out before moving on to the user interface, I added a client side partial class for the Earthquake entity that contains helper properties that we will bind to later: using System;   namespace EarthquakeLocator.Web.Model {     /// <summary>     /// Represents an earthquake occurrence and related information.     /// </summary>     public partial class Earthquake     {         /// <summary>         /// Gets the location based on the current Latitude/Longitude.         /// </summary>         /// <value>The location.</value>         public string Location         {             get { return String.Format("{0},{1}", Latitude, Longitude); }         }           /// <summary>         /// Gets the size based on the Magnitude.         /// </summary>         /// <value>The size.</value>         public double Size         {             get { return (Magnitude * 3); }         }     } }   View Now the fun part! Usually, I would create a Views folder to place all of my View controls in, but I took the easy way out and added the following XAML code to the default MainPage.xaml file. Be sure to add the bing prefix associating the Microsoft.Maps.MapControl namespace after adding the assembly reference to your project. The MVVM Light Toolkit project templates come with a ViewModelLocator class that you can use via a static resource, but I am instantiating the EarthquakeViewModel directly in my user control. I am setting the AutoLoadData property to true as a way to trigger the LoadEarthquakes() method call. The MapItemsControl found within the <bing:Map> control binds its ItemsSource property to the Earthquakes collection of the view model, and since it is an ObservableCollection<T>, we get the automatic two way data binding via the INotifyCollectionChanged interface. <UserControl x:Class="EarthquakeLocator.MainPage"     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"     xmlns:d="http://schemas.microsoft.com/expression/blend/2008"     xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"     xmlns:bing="clr-namespace:Microsoft.Maps.MapControl;assembly=Microsoft.Maps.MapControl"     xmlns:vm="clr-namespace:EarthquakeLocator.ViewModel"     mc:Ignorable="d" d:DesignWidth="640" d:DesignHeight="480" >     <UserControl.Resources>         <DataTemplate x:Key="EarthquakeTemplate">             <Ellipse Fill="Red" Stroke="Black" StrokeThickness="1"                      Width="{Binding Size}" Height="{Binding Size}"                      bing:MapLayer.Position="{Binding Location}"                      bing:MapLayer.PositionOrigin="Center">                 <ToolTipService.ToolTip>                     <StackPanel>                         <TextBlock Text="{Binding Title}" FontSize="14" FontWeight="Bold" />                         <TextBlock Text="{Binding UtcTime}" />                         <TextBlock Text="{Binding LocalTime}" />                         <TextBlock Text="{Binding DepthDesc}" />                     </StackPanel>                 </ToolTipService.ToolTip>             </Ellipse>         </DataTemplate>     </UserControl.Resources>       <UserControl.DataContext>         <vm:EarthquakeViewModel AutoLoadData="True" />     </UserControl.DataContext>       <Grid x:Name="LayoutRoot">           <bing:Map x:Name="map" CredentialsProvider="--Your-Bing-Maps-Key--"                   Center="{Binding MapCenter, Mode=TwoWay}"                   ZoomLevel="{Binding ZoomLevel, Mode=TwoWay}">             <bing:MapItemsControl ItemsSource="{Binding Earthquakes}"                                   ItemTemplate="{StaticResource EarthquakeTemplate}" />         </bing:Map>       </Grid> </UserControl>   The EarthquakeTemplate defines the Ellipse that will represent each earthquake, the Width and Height that are determined by the Magnitude, the Position on the map, and also the tooltip that will appear when we mouse over each data point. Running the application will give us the following result (shown with a tooltip example): That concludes this portion of our show but I plan on implementing additional functionality in later blog posts. Be sure to come back soon to see the next installments in this series.

  • Pure Front end JavaScript with Web API versus MVC views with ajax

    - by eyeballpaul
    This was more a discussion for what peoples thoughts are these days on how to split a web application. I am used to creating an MVC application with all its views and controllers. I would normally create a full view and pass this back to the browser on a full page request, unless there were specific areas that I did not want to populate straight away and would then use DOM page load events to call the server to load other areas using AJAX. Also, when it came to partial page refreshing, I would call an MVC action method which would return the HTML fragment which I could then use to populate parts of the page. This would be for areas that I did not want to slow down initial page load, or areas that fitted better with AJAX calls. One example would be for table paging. If you want to move on to the next page, I would prefer it if an AJAX call got that info rather than using a full page refresh. But the AJAX call would still return an HTML fragment. My question is. Are my thoughts on this archaic because I come from a .net background rather than a pure front end background? An intelligent front end developer that I work with, prefers to do more or less nothing in the MVC views, and would rather do everything on the front end. Right down to web API calls populating the page. So that rather than calling an MVC action method, which returns HTML, he would prefer to return a standard object and use javascript to create all the elements of the page. The front end developer way means that any benefits that I normally get with MVC model validation, including client side validation, would be gone. It also means that any benefits that I get with creating the views, with strongly typed html templates etc would be gone. I believe this would mean I would need to write the same validation for front end and back end validation. The javascript would also need to have lots of methods for creating all the different parts of the DOM. For example, when adding a new row to a table, I would normally use the MVC partial view for creating the row, and then return this as part of the AJAX call, which then gets injected into the table. By using a pure front end way, the javascript would would take in an object (for, say, a product) for the row from the api call, and then create a row from that object. Creating each individual part of the table row. The website in question will have lots of different areas, from administration, forms, product searching etc. A website that I don't think requires to be architected in a single page application way. What are everyone's thoughts on this? I am interested to hear from front end devs and back end devs.

  • Creating Wizard in ASP.NET MVC (Part 3 - jQuery)

    - by bipinjoshi
    In Part 1 and Part 2 of this article series you developed a wizard in an ASP.NET MVC application using full page postback and Ajax helper respectively. In this final part of this series you will develop a client side wizard using jQuery. The navigation between various wizard steps (Next, Previous) happens without any postback (neither full nor partial). The only step that causes form submission to the server is clicking on the Finish wizard button.http://www.binaryintellect.net/articles/d278e8aa-3f37-40c5-92a2-74e65b1b5653.aspx

  • Ajaxy

    - by Chris Skardon
    Today is the big day, the day I attempt to use Ajax in the app… I’ve never done this (well, tell a lie, I’ve done it in a ‘tutorial’ site, but that was a while ago now), so it’s going to be interesting.. OK, basics first, let’s start with the @Ajax.ActionLink Right, first stab: @Ajax.ActionLink("Click to get latest", "LatestEntry", new AjaxOptions { UpdateTargetId = "ajaxEntrant", InsertionMode = InsertionMode.Replace, HttpMethod = "GET" }) As far as I’m aware, I’m asking to get the ‘LatestEntry’ from the current controller, and in doing so, I will replace the #ajaxEntrant DOM bit with the result. So. I guess I’d better get the result working… To the controller! public PartialResult LatestEntry() { var entrant =_db.Entrants.OrderByDescending(e => e.Id).Single(); return PartialView("_Entrant", entrant); } Pretty simple, just returns the last entry in a PartialView… but! I have yet to make my partial view, so onto that! @model Webby.Entrant <div class="entrant"> <h4>@Model.Name</h4> </div> Again, super simple, (I’m really just testing at this point)… All the code is now there (as far as I know), so F5 and in… And once again, in the traditionally disappointing way of the norm, it doesn’t work, sure… it opens the right view, but it doesn’t replace the #ajaxEntry DOM element, rather it replaces the whole page… The source code (again, as far as I know) looks ok: <a data-ajax="true" data-ajax-method="GET" data-ajax-mode="replace" data-ajax-update="#ajaxEntrants" href="/Entrants/LatestEntrant">Click to get latest</a> Changing the InsertionMode to any of the other modes has the same effect.. It’s not the DOM name either, changing that has the same effect.. i.e. none. It’s not the partial view either, just making that a <p> has (again) no effect… Ahhhhh --- what a schoolboy error… I had neglected (ahem) to actually put the script bit into the calling page (another save from stackoverflow): <script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script> I’ve now stuck that into the _Layout.cshtml view temporarily to aid the development process… :) Onwards and upwards!
