  • How to link a UIViewController to a NIB file?

    - by jcdmb
    Hi everyone, I'm reading O'reilly's Learning iPhone Programming and on page 79 it says I have to create a new file (UIViewController subclass) and thick the checkbox to ask Xcode to generate an associated NIB file. The problem is: I do not have this option in my XCode 3.1 (this options is from XCode 3.2). So, I have to do it manually, and I don't know how. Could someone please help me? Thanks in advance!

  • How to style forms in the Zend framework?

    - by user505988
    Hi, I really like the idea of putting forms into a seperate class that manages validation etc, but I don't like everything ending up in a DL and also not being able to use square bracket notation in post elements like <input type='checkbox' name='data[]'>. Is there another way of generating forms - like in views so I can style them the way I want, but also keeping the validation aspect? Also how would I load this view into my current view (using partial view somehow?)

  • Inputs inside ListView doesn't change values from old to recently set on ItemUpdating event

    - by Tema
    Hi, I would appreciate if someone help me to understand this situation. I do not know why but when i edit selected ListView item (containing few TextBoxes) and then press Update button in the ItemUpdating event i always get old values instead of those which were typed recently. Why? I do not use Page_Load event so i do not need check on PostBack I try to get value before i bind data from DB to ListView, so it can't override recently typed values I tried to get TextBoxes values in different Event handlers - ItemCommand, ItemUpdating, ItemDataBound - result si always the same Collection NewValues and OldValues are always empty (i think this is because i don't use SqlDataSource control) The only one way i can get new values - is to check Request, but in this case i can't use control validators ... so probably it is bad idea to work with only request. This is the code of ItemUpdating method: ListViewItem editItem = AdminUsersListView.EditItem; Guid userId = new Guid((editItem.FindControl("UserId") as HiddenField).Value); Hashtable dataUpdate = new Hashtable { { "UserName", Request[ (editItem.FindControl("UserNameNew") as TextBox).UniqueID ] }, { "Email", Request[ (editItem.FindControl("Email") as TextBox).UniqueID ] }, { "IsApproved", Request[ (editItem.FindControl("IsApproved") as CheckBox).UniqueID ] == "on" }, { "IsLockedOut", Request[ (editItem.FindControl("IsLockedOut") as CheckBox).UniqueID ] == "on" } }; var x1 = dataUpdate["UserName"]; // this is corrent new value from Request var x2 = (editItem.FindControl("UserNameNew") as TextBox).Text; // this is WRONG! OLD! value from TextBox ... Why??? using (Entities entities = new Entities()) { aspnet_Membership membershipItem = entities.aspnet_Membership.Where(MBS => MBS.UserId == userId).FirstOrDefault(); membershipItem.Email = dataUpdate["Email"].ToString(); membershipItem.LoweredEmail = membershipItem.Email.ToLower(); membershipItem.IsApproved = Convert.ToBoolean(dataUpdate["IsApproved"]); membershipItem.IsLockedOut = Convert.ToBoolean(dataUpdate["IsLockedOut"]); entities.SaveChanges(); aspnet_Users userItem = entities.aspnet_Users.Where(USR => USR.UserId == userId).FirstOrDefault(); userItem.UserName = dataUpdate["UserName"].ToString(); userItem.LoweredUserName = userItem.UserName.ToLower(); entities.SaveChanges(); } AdminUsersListView.EditIndex = -1; AdminUsersListView.DataSource = _getDataList(); AdminUsersListView.DataBind(); Thanks, Art

  • how can i edit the action of the buttons in the dialog box in jquery?

    - by noob
    this code is from the demo of modal confirmation from jquery's site. <script type="text/javascript"> $(function() { $("#dialog").dialog({ bgiframe: true, resizable: false, height:140, modal: true, overlay: { backgroundColor: '#000', opacity: 0.5 }, buttons: { 'Yes': function() { $(this).dialog('close'); }, 'No': function() { $(this).dialog('close'); } } }); }); </script> <div class="demo"> <div id="dialog" title="Empty the recycle bin?"> <p><span class="ui-icon ui-icon-alert" style="float:left; margin:0 7px 20px 0;"></span>These items will be permanently deleted and cannot be recovered.

  • Change xml attribute in foreach statement c#

    - by user1913479
    I need to save XML-attribute value in a database, using information if checkbox is checked. If checkbox is checked, the attribute value is "TRUE", otherwise it's false. When I use foreach statement, the last enumerated value is usually assigned. Here is the part of my code: XmlAttribute xmlAttribute = xmlDoc.CreateAttribute("BooleanValue"); foreach (string value in list) //list is a List<object> { XmlNode xmlNode = xmlDoc.CreateNode(XmlNodeType.Element, "VALUE", ""); if (checkBox1.Checked || checkBox2.Checked || checkBox3.Checked) xmlAttribute.Value = "TRUE"; if (!checkBox1.Checked || !checkBox2.Checked || !checkBox3.Checked) xmlAttribute.Value = "FALSE"; xmlNode.Attributes.Append(xmlAttribute); xmlNode.InnerText = val; childNode.AppendChild(xmlNode); } When I run my application, I get an XML attribute xmlAttribute "FALSE" value anyway. What I need to have: I need to have the following XML: <ROOT><NODE><VALUE ATTRIBUTE="TRUE">Value 1</VALUE></NODE> <NODE><VALUE ATTRIBUTE="TRUE">Value 2</VALUE></NODE> <NODE><VALUE ATTRIBUTE="FALSE">Value 3</VALUE></NODE> <NODE><VALUE ATTRIBUTE="FALSE">Value 4</VALUE></NODE> <NODE><VALUE ATTRIBUTE="TRUE">Value 5</VALUE></NODE> <NODE><VALUE ATTRIBUTE="FALSE">Value 6</VALUE></NODE> </ROOT> What I actually get: <ROOT><NODE><VALUE ATTRIBUTE="FALSE">Value 1</VALUE></NODE> <NODE><VALUE ATTRIBUTE="FALSE">Value 2</VALUE></NODE> <NODE><VALUE ATTRIBUTE="FALSE">Value 3</VALUE></NODE> <NODE><VALUE ATTRIBUTE="FALSE">Value 4</VALUE></NODE> <NODE><VALUE ATTRIBUTE="FALSE">Value 5</VALUE></NODE> <NODE><VALUE ATTRIBUTE="FALSE">Value 6</VALUE></NODE> </ROOT> Because in C# FALSE value is stayed at last position in foreach loop The question is: how do I do to assign the correct values of my attribute. Thanks

  • Does this type of function or technique have a name?

    - by DHR
    HI there, I'm slightly new to programming, more of a hobby. I am wondering if a the following logic or technique has a specific name, or term. My current project has 7 check boxes, one for each day of the week. I needed an easy to save which boxes were checked. The following is the method to saved the checked boxes to a single number. Each checkbox gets a value that is double from the last check box. When I want to find out which boxes are checked, I work backwards, and see how many times I can divide the total value by the checkbox value. private int SetSelectedDays() { int selectedDays = 0; selectedDays += (dayMon.Checked) ? 1 : 0; selectedDays += (dayTue.Checked) ? 2 : 0; selectedDays += (dayWed.Checked) ? 4 : 0; selectedDays += (dayThu.Checked) ? 8 : 0; selectedDays += (dayFri.Checked) ? 16 : 0; selectedDays += (daySat.Checked) ? 32 : 0; selectedDays += (daySun.Checked) ? 64 : 0; return selectedDays; } private void SelectedDays(int n) { if ((n / 64 >= 1) & !(n / 64 >= 2)) { n -= 64; daySun.Checked = true; } if ((n / 32 >= 1) & !(n / 32 >= 2)) { n -= 32; daySat.Checked = true; } if ((n / 16 >= 1) & !(n / 16 >= 2)) { n -= 16; dayFri.Checked = true; } if ((n / 8 >= 1) & !(n / 8 >= 2)) { n -= 8; dayThu.Checked = true; } if ((n / 4 >= 1) & !(n / 4 >= 2)) { n -= 4; dayWed.Checked = true; } if ((n / 2 >= 1) & !(n / 2 >= 2)) { n -= 2; dayTue.Checked = true; } if ((n / 1 >= 1) & !(n / 1 >= 2)) { n -= 1; dayMon.Checked = true; } if (n > 0) { //log event } } The method works well for what I need it for, however, if you do see another way of doing this, or a better way to writing, I would be interested in your suggestions.

    - by PIKP
    I have the following html markup inside a Div named item and I want to select all the elements (inside nested divs) and clear the values. As shown in following given Jquery I have managed to access elements in each Div by using.children().each(). But the the problem is .children().each()goes one level down at a time from the parent div, so I have repeated the same code block with multiple .children() to access the elements inside nested Divs, can anyone suggest me a method to do this without repeating the code for N number of nested divs . html markup <div class="item"> <input type="hidden" value="1234" name="testVal"> <div class="form-group" id="c1"> <div class="controls "> <input type="text" value="Results" name="s1" maxlength="255" id="id2"> </div> </div> <div class="form-group" id="id4"> <input type="text" value="Results" name="s12" maxlength="255" id="id225"> <div class="form-group" id="id41"> <input type="text" value="Results" name="s12" maxlength="255" id="5"> <div class="form-group" id="id42"> <input type="text" value="Results" name="s12" maxlength="255" id="5"> <div class="form-group" id="id43"> <input type="text" value="Results" name="s12" maxlength="255" id="id224"> </div> </div> </div> </div> </div> My Qjuery script var row = $(".item:first").clone(false).get(0); $(row).children().each(function () { updateElementIndex(this, prefix, formCount); if ($(this).attr('type') == 'text') { $(this).val(''); } if ($(this).attr('type') == 'hidden' && ($(this).attr('name') != 'csrfmiddlewaretoken')) { $(this).val(''); } if ($(this).attr('type') == 'file') { $(this).val(''); } if ($(this).attr('type') == 'checkbox') { $(this).attr('checked', false); } $(this).remove('a'); }); // Relabel or rename all the relevant bits $(row).children().children().each(function () { updateElementIndex(this, prefix, formCount) if ($(this).attr('type') == 'text') { $(this).val(''); } if ($(this).attr('type') == 'hidden' && ($(this).attr('name') != 'csrfmiddlewaretoken')) { $(this).val(''); } if ($(this).attr('type') == 'file') { $(this).val(''); } if ($(this).attr('type') == 'checkbox') { $(this).attr('checked', false); } $(this).remove('a'); });

  • Windows Azure: Import/Export Hard Drives, VM ACLs, Web Sockets, Remote Debugging, Continuous Delivery, New Relic, Billing Alerts and More

    - by ScottGu
    Two weeks ago we released a giant set of improvements to Windows Azure, as well as a significant update of the Windows Azure SDK. This morning we released another massive set of enhancements to Windows Azure.  Today’s new capabilities include: Storage: Import/Export Hard Disk Drives to your Storage Accounts HDInsight: General Availability of our Hadoop Service in the cloud Virtual Machines: New VM Gallery, ACL support for VIPs Web Sites: WebSocket and Remote Debugging Support Notification Hubs: Segmented customer push notification support with tag expressions TFS & GIT: Continuous Delivery Support for Web Sites + Cloud Services Developer Analytics: New Relic support for Web Sites + Mobile Services Service Bus: Support for partitioned queues and topics Billing: New Billing Alert Service that sends emails notifications when your bill hits a threshold you define All of these improvements are now available to use immediately (note that some features are still in preview).  Below are more details about them. Storage: Import/Export Hard Disk Drives to Windows Azure I am excited to announce the preview of our new Windows Azure Import/Export Service! The Windows Azure Import/Export Service enables you to move large amounts of on-premises data into and out of your Windows Azure Storage accounts. It does this by enabling you to securely ship hard disk drives directly to our Windows Azure data centers. Once we receive the drives we’ll automatically transfer the data to or from your Windows Azure Storage account.  This enables you to import or export massive amounts of data more quickly and cost effectively (and not be constrained by available network bandwidth). Encrypted Transport Our Import/Export service provides built-in support for BitLocker disk encryption – which enables you to securely encrypt data on the hard drives before you send it, and not have to worry about it being compromised even if the disk is lost/stolen in transit (since the content on the transported hard drives is completely encrypted and you are the only one who has the key to it).  The drive preparation tool we are shipping today makes setting up bitlocker encryption on these hard drives easy. How to Import/Export your first Hard Drive of Data You can read our Getting Started Guide to learn more about how to begin using the import/export service.  You can create import and export jobs via the Windows Azure Management Portal as well as programmatically using our Server Management APIs. It is really easy to create a new import or export job using the Windows Azure Management Portal.  Simply navigate to a Windows Azure storage account, and then click the new Import/Export tab now available within it (note: if you don’t have this tab make sure to sign-up for the Import/Export preview): Then click the “Create Import Job” or “Create Export Job” commands at the bottom of it.  This will launch a wizard that easily walks you through the steps required: For more comprehensive information about Import/Export, refer to Windows Azure Storage team blog.  You can also send questions and comments to the [email protected] email address. We think you’ll find this new service makes it much easier to move data into and out of Windows Azure, and it will dramatically cut down the network bandwidth required when working on large data migration projects.  We hope you like it. HDInsight: 100% Compatible Hadoop Service in the Cloud Last week we announced the general availability release of Windows Azure HDInsight. HDInsight is a 100% compatible Hadoop service that allows you to easily provision and manage Hadoop clusters for big data processing in Windows Azure.  This release is now live in production, backed by an enterprise SLA, supported 24x7 by Microsoft Support, and is ready to use for production scenarios. HDInsight allows you to use Apache Hadoop tools, such as Pig and Hive, to process large amounts of data in Windows Azure Blob Storage. Because data is stored in Windows Azure Blob Storage, you can choose to dynamically create Hadoop clusters only when you need them, and then shut them down when they are no longer required (since you pay only for the time the Hadoop cluster instances are running this provides a super cost effective way to use them).  You can create Hadoop clusters using either the Windows Azure Management Portal (see below) or using our PowerShell and Cross Platform Command line tools: The import/export hard drive support that came out today is a perfect companion service to use with HDInsight – the combination allows you to easily ingest, process and optionally export a limitless amount of data.  We’ve also integrated HDInsight with our Business Intelligence tools, so users can leverage familiar tools like Excel in order to analyze the output of jobs.  You can find out more about how to get started with HDInsight here. Virtual Machines: VM Gallery Enhancements Today’s update of Windows Azure brings with it a new Virtual Machine gallery that you can use to create new VMs in the cloud.  You can launch the gallery by doing New->Compute->Virtual Machine->From Gallery within the Windows Azure Management Portal: The new Virtual Machine Gallery includes some nice enhancements that make it even easier to use: Search: You can now easily search and filter images using the search box in the top-right of the dialog.  For example, simply type “SQL” and we’ll filter to show those images in the gallery that contain that substring. Category Tree-view: Each month we add more built-in VM images to the gallery.  You can continue to browse these using the “All” view within the VM Gallery – or now quickly filter them using the category tree-view on the left-hand side of the dialog.  For example, by selecting “Oracle” in the tree-view you can now quickly filter to see the official Oracle supplied images. MSDN and Supported checkboxes: With today’s update we are also introducing filters that makes it easy to filter out types of images that you may not be interested in. The first checkbox is MSDN: using this filter you can exclude any image that is not part of the Windows Azure benefits for MSDN subscribers (which have highly discounted pricing - you can learn more about the MSDN pricing here). The second checkbox is Supported: this filter will exclude any image that contains prerelease software, so you can feel confident that the software you choose to deploy is fully supported by Windows Azure and our partners. Sort options: We sort gallery images by what we think customers are most interested in, but sometimes you might want to sort using different views. So we’re providing some additional sort options, like “Newest,” to customize the image list for what suits you best. Pricing information: We now provide additional pricing information about images and options on how to cost effectively run them directly within the VM Gallery. The above improvements make it even easier to use the VM Gallery and quickly create launch and run Virtual Machines in the cloud. Virtual Machines: ACL Support for VIPs A few months ago we exposed the ability to configure Access Control Lists (ACLs) for Virtual Machines using Windows PowerShell cmdlets and our Service Management API. With today’s release, you can now configure VM ACLs using the Windows Azure Management Portal as well. You can now do this by clicking the new Manage ACL command in the Endpoints tab of a virtual machine instance: This will enable you to configure an ordered list of permit and deny rules to scope the traffic that can access your VM’s network endpoints. For example, if you were on a virtual network, you could limit RDP access to a Windows Azure virtual machine to only a few computers attached to your enterprise. Or if you weren’t on a virtual network you could alternatively limit traffic from public IPs that can access your workloads: Here is the default behaviors for ACLs in Windows Azure: By default (i.e. no rules specified), all traffic is permitted. When using only Permit rules, all other traffic is denied. When using only Deny rules, all other traffic is permitted. When there is a combination of Permit and Deny rules, all other traffic is denied. Lastly, remember that configuring endpoints does not automatically configure them within the VM if it also has firewall rules enabled at the OS level.  So if you create an endpoint using the Windows Azure Management Portal, Windows PowerShell, or REST API, be sure to also configure your guest VM firewall appropriately as well. Web Sites: Web Sockets Support With today’s release you can now use Web Sockets with Windows Azure Web Sites.  This feature enables you to easily integrate real-time communication scenarios within your web based applications, and is available at no extra charge (it even works with the free tier).  Higher level programming libraries like SignalR and socket.io are also now supported with it. You can enable Web Sockets support on a web site by navigating to the Configure tab of a Web Site, and by toggling Web Sockets support to “on”: Once Web Sockets is enabled you can start to integrate some really cool scenarios into your web applications.  Check out the new SignalR documentation hub on www.asp.net to learn more about some of the awesome scenarios you can do with it. Web Sites: Remote Debugging Support The Windows Azure SDK 2.2 we released two weeks ago introduced remote debugging support for Windows Azure Cloud Services. With today’s Windows Azure release we are extending this remote debugging support to also work with Windows Azure Web Sites. With live, remote debugging support inside of Visual Studio, you are able to have more visibility than ever before into how your code is operating live in Windows Azure. It is now super easy to attach the debugger and quickly see what is going on with your application in the cloud. Remote Debugging of a Windows Azure Web Site using VS 2013 Enabling the remote debugging of a Windows Azure Web Site using VS 2013 is really easy.  Start by opening up your web application’s project within Visual Studio. Then navigate to the “Server Explorer” tab within Visual Studio, and click on the deployed web-site you want to debug that is running within Windows Azure using the Windows Azure->Web Sites node in the Server Explorer.  Then right-click and choose the “Attach Debugger” option on it: When you do this Visual Studio will remotely attach the debugger to the Web Site running within Windows Azure.  The debugger will then stop the web site’s execution when it hits any break points that you have set within your web application’s project inside Visual Studio.  For example, below I set a breakpoint on the “ViewBag.Message” assignment statement within the HomeController of the standard ASP.NET MVC project template.  When I hit refresh on the “About” page of the web site within the browser, the breakpoint was triggered and I am now able to debug the app remotely using Visual Studio: Note above how we can debug variables (including autos/watchlist/etc), as well as use the Immediate and Command Windows. In the debug session above I used the Immediate Window to explore some of the request object state, as well as to dynamically change the ViewBag.Message property.  When we click the the “Continue” button (or press F5) the app will continue execution and the Web Site will render the content back to the browser.  This makes it super easy to debug web apps remotely. Tips for Better Debugging To get the best experience while debugging, we recommend publishing your site using the Debug configuration within Visual Studio’s Web Publish dialog. This will ensure that debug symbol information is uploaded to the Web Site which will enable a richer debug experience within Visual Studio.  You can find this option on the Web Publish dialog on the Settings tab: When you ultimately deploy/run the application in production we recommend using the “Release” configuration setting – the release configuration is memory optimized and will provide the best production performance.  To learn more about diagnosing and debugging Windows Azure Web Sites read our new Troubleshooting Windows Azure Web Sites in Visual Studio guide. Notification Hubs: Segmented Push Notification support with tag expressions In August we announced the General Availability of Windows Azure Notification Hubs - a powerful Mobile Push Notifications service that makes it easy to send high volume push notifications with low latency from any mobile app back-end.  Notification hubs can be used with any mobile app back-end (including ones built using our Mobile Services capability) and can also be used with back-ends that run in the cloud as well as on-premises. Beginning with the initial release, Notification Hubs allowed developers to send personalized push notifications to both individual users as well as groups of users by interest, by associating their devices with tags representing the logical target of the notification. For example, by registering all devices of customers interested in a favorite MLB team with a corresponding tag, it is possible to broadcast one message to millions of Boston Red Sox fans and another message to millions of St. Louis Cardinals fans with a single API call respectively. New support for using tag expressions to enable advanced customer segmentation With today’s release we are adding support for even more advanced customer targeting.  You can now identify customers that you want to send push notifications to by defining rich tag expressions. With tag expressions, you can now not only broadcast notifications to Boston Red Sox fans, but take that segmenting a step farther and reach more granular segments. This opens up a variety of scenarios, for example: Offers based on multiple preferences—e.g. send a game day vegetarian special to users tagged as both a Boston Red Sox fan AND a vegetarian Push content to multiple segments in a single message—e.g. rain delay information only to users who are tagged as either a Boston Red Sox fan OR a St. Louis Cardinal fan Avoid presenting subsets of a segment with irrelevant content—e.g. season ticket availability reminder to users who are tagged as a Boston Red Sox fan but NOT also a season ticket holder To illustrate with code, consider a restaurant chain app that sends an offer related to a Red Sox vs Cardinals game for users in Boston. Devices can be tagged by your app with location tags (e.g. “Loc:Boston”) and interest tags (e.g. “Follows:RedSox”, “Follows:Cardinals”), and then a notification can be sent by your back-end to “(Follows:RedSox || Follows:Cardinals) && Loc:Boston” in order to deliver an offer to all devices in Boston that follow either the RedSox or the Cardinals. This can be done directly in your server backend send logic using the code below: var notification = new WindowsNotification(messagePayload); hub.SendNotificationAsync(notification, "(Follows:RedSox || Follows:Cardinals) && Loc:Boston"); In your expressions you can use all Boolean operators: AND (&&), OR (||), and NOT (!).  Some other cool use cases for tag expressions that are now supported include: Social: To “all my group except me” - group:id && !user:id Events: Touchdown event is sent to everybody following either team or any of the players involved in the action: Followteam:A || Followteam:B || followplayer:1 || followplayer:2 … Hours: Send notifications at specific times. E.g. Tag devices with time zone and when it is 12pm in Seattle send to: GMT8 && follows:thaifood Versions and platforms: Send a reminder to people still using your first version for Android - version:1.0 && platform:Android For help on getting started with Notification Hubs, visit the Notification Hub documentation center.  Then download the latest NuGet package (or use the Notification Hubs REST APIs directly) to start sending push notifications using tag expressions.  They are really powerful and enable a bunch of great new scenarios. TFS & GIT: Continuous Delivery Support for Web Sites + Cloud Services With today’s Windows Azure release we are making it really easy to enable continuous delivery support with Windows Azure and Team Foundation Services.  Team Foundation Services is a cloud based offering from Microsoft that provides integrated source control (with both TFS and Git support), build server, test execution, collaboration tools, and agile planning support.  It makes it really easy to setup a team project (complete with automated builds and test runners) in the cloud, and it has really rich integration with Visual Studio. With today’s Windows Azure release it is now really easy to enable continuous delivery support with both TFS and Git based repositories hosted using Team Foundation Services.  This enables a workflow where when code is checked in, built successfully on an automated build server, and all tests pass on it – I can automatically have the app deployed on Windows Azure with zero manual intervention or work required. The below screen-shots demonstrate how to quickly setup a continuous delivery workflow to Windows Azure with a Git-based ASP.NET MVC project hosted using Team Foundation Services. Enabling Continuous Delivery to Windows Azure with Team Foundation Services The project I’m going to enable continuous delivery with is a simple ASP.NET MVC project whose source code I’m hosting using Team Foundation Services.  I did this by creating a “SimpleContinuousDeploymentTest” repository there using Git – and then used the new built-in Git tooling support within Visual Studio 2013 to push the source code to it.  Below is a screen-shot of the Git repository hosted within Team Foundation Services: I can access the repository within Visual Studio 2013 and easily make commits with it (as well as branch, merge and do other tasks).  Using VS 2013 I can also setup automated builds to take place in the cloud using Team Foundation Services every time someone checks in code to the repository: The cool thing about this is that I don’t have to buy or rent my own build server – Team Foundation Services automatically maintains its own build server farm and can automatically queue up a build for me (for free) every time someone checks in code using the above settings.  This build server (and automated testing) support now works with both TFS and Git based source control repositories. Connecting a Team Foundation Services project to Windows Azure Once I have a source repository hosted in Team Foundation Services with Automated Builds and Testing set up, I can then go even further and set it up so that it will be automatically deployed to Windows Azure when a source code commit is made to the repository (assuming the Build + Tests pass).  Enabling this is now really easy.  To set this up with a Windows Azure Web Site simply use the New->Compute->Web Site->Custom Create command inside the Windows Azure Management Portal.  This will create a dialog like below.  I gave the web site a name and then made sure the “Publish from source control” checkbox was selected: When we click next we’ll be prompted for the location of the source repository.  We’ll select “Team Foundation Services”: Once we do this we’ll be prompted for our Team Foundation Services account that our source repository is hosted under (in this case my TFS account is “scottguthrie”): When we click the “Authorize Now” button we’ll be prompted to give Windows Azure permissions to connect to the Team Foundation Services account.  Once we do this we’ll be prompted to pick the source repository we want to connect to.  Starting with today’s Windows Azure release you can now connect to both TFS and Git based source repositories.  This new support allows me to connect to the “SimpleContinuousDeploymentTest” respository we created earlier: Clicking the finish button will then create the Web Site with the continuous delivery hooks setup with Team Foundation Services.  Now every time someone pushes source control to the repository in Team Foundation Services, it will kick off an automated build, run all of the unit tests in the solution , and if they pass the app will be automatically deployed to our Web Site in Windows Azure.  You can monitor the history and status of these automated deployments using the Deployments tab within the Web Site: This enables a really slick continuous delivery workflow, and enables you to build and deploy apps in a really nice way. Developer Analytics: New Relic support for Web Sites + Mobile Services With today’s Windows Azure release we are making it really easy to enable Developer Analytics and Monitoring support with both Windows Azure Web Site and Windows Azure Mobile Services.  We are partnering with New Relic, who provide a great dev analytics and app performance monitoring offering, to enable this - and we have updated the Windows Azure Management Portal to make it really easy to configure. Enabling New Relic with a Windows Azure Web Site Enabling New Relic support with a Windows Azure Web Site is now really easy.  Simply navigate to the Configure tab of a Web Site and scroll down to the “developer analytics” section that is now within it: Clicking the “add-on” button will display some additional UI.  If you don’t already have a New Relic subscription, you can click the “view windows azure store” button to obtain a subscription (note: New Relic has a perpetually free tier so you can enable it even without paying anything): Clicking the “view windows azure store” button will launch the integrated Windows Azure Store experience we have within the Windows Azure Management Portal.  You can use this to browse from a variety of great add-on services – including New Relic: Select “New Relic” within the dialog above, then click the next button, and you’ll be able to choose which type of New Relic subscription you wish to purchase.  For this demo we’ll simply select the “Free Standard Version” – which does not cost anything and can be used forever:  Once we’ve signed-up for our New Relic subscription and added it to our Windows Azure account, we can go back to the Web Site’s configuration tab and choose to use the New Relic add-on with our Windows Azure Web Site.  We can do this by simply selecting it from the “add-on” dropdown (it is automatically populated within it once we have a New Relic subscription in our account): Clicking the “Save” button will then cause the Windows Azure Management Portal to automatically populate all of the needed New Relic configuration settings to our Web Site: Deploying the New Relic Agent as part of a Web Site The final step to enable developer analytics using New Relic is to add the New Relic runtime agent to our web app.  We can do this within Visual Studio by right-clicking on our web project and selecting the “Manage NuGet Packages” context menu: This will bring up the NuGet package manager.  You can search for “New Relic” within it to find the New Relic agent.  Note that there is both a 32-bit and 64-bit edition of it – make sure to install the version that matches how your Web Site is running within Windows Azure (note: you can configure your Web Site to run in either 32-bit or 64-bit mode using the Web Site’s “Configuration” tab within the Windows Azure Management Portal): Once we install the NuGet package we are all set to go.  We’ll simply re-publish the web site again to Windows Azure and New Relic will now automatically start monitoring the application Monitoring a Web Site using New Relic Now that the application has developer analytics support with New Relic enabled, we can launch the New Relic monitoring portal to start monitoring the health of it.  We can do this by clicking on the “Add Ons” tab in the left-hand side of the Windows Azure Management Portal.  Then select the New Relic add-on we signed-up for within it.  The Windows Azure Management Portal will provide some default information about the add-on when we do this.  Clicking the “Manage” button in the tray at the bottom will launch a new browser tab and single-sign us into the New Relic monitoring portal associated with our account: When we do this a new browser tab will launch with the New Relic admin tool loaded within it: We can now see insights into how our app is performing – without having to have written a single line of monitoring code.  The New Relic service provides a ton of great built-in monitoring features allowing us to quickly see: Performance times (including browser rendering speed) for the overall site and individual pages.  You can optionally set alert thresholds to trigger if the speed does not meet a threshold you specify. Information about where in the world your customers are hitting the site from (and how performance varies by region) Details on the latency performance of external services your web apps are using (for example: SQL, Storage, Twitter, etc) Error information including call stack details for exceptions that have occurred at runtime SQL Server profiling information – including which queries executed against your database and what their performance was And a whole bunch more… The cool thing about New Relic is that you don’t need to write monitoring code within your application to get all of the above reports (plus a lot more).  The New Relic agent automatically enables the CLR profiler within applications and automatically captures the information necessary to identify these.  This makes it super easy to get started and immediately have a rich developer analytics view for your solutions with very little effort. If you haven’t tried New Relic out yet with Windows Azure I recommend you do so – I think you’ll find it helps you build even better cloud applications.  Following the above steps will help you get started and deliver you a really good application monitoring solution in only minutes. Service Bus: Support for partitioned queues and topics With today’s release, we are enabling support within Service Bus for partitioned queues and topics. Enabling partitioning enables you to achieve a higher message throughput and better availability from your queues and topics. Higher message throughput is achieved by implementing multiple message brokers for each partitioned queue and topic.  The  multiple messaging stores will also provide higher availability. You can create a partitioned queue or topic by simply checking the Enable Partitioning option in the custom create wizard for a Queue or Topic: Read this article to learn more about partitioned queues and topics and how to take advantage of them today. Billing: New Billing Alert Service Today’s Windows Azure update enables a new Billing Alert Service Preview that enables you to get proactive email notifications when your Windows Azure bill goes above a certain monetary threshold that you configure.  This makes it easier to manage your bill and avoid potential surprises at the end of the month. With the Billing Alert Service Preview, you can now create email alerts to monitor and manage your monetary credits or your current bill total.  To set up an alert first sign-up for the free Billing Alert Service Preview.  Then visit the account management page, click on a subscription you have setup, and then navigate to the new Alerts tab that is available: The alerts tab allows you to setup email alerts that will be sent automatically once a certain threshold is hit.  For example, by clicking the “add alert” button above I can setup a rule to send myself email anytime my Windows Azure bill goes above $100 for the month: The Billing Alert Service will evolve to support additional aspects of your bill as well as support multiple forms of alerts such as SMS.  Try out the new Billing Alert Service Preview today and give us feedback. Summary Today’s Windows Azure release enables a ton of great new scenarios, and makes building applications hosted in the cloud even easier. If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using all of the above features today.  Then visit the Windows Azure Developer Center to learn more about how to build apps with it. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

  • Ajax Control Toolkit Now Supports jQuery

    - by Stephen.Walther
    I’m excited to announce the September 2013 release of the Ajax Control Toolkit, which now supports building new Ajax Control Toolkit controls with jQuery. You can download the latest release of the Ajax Control Toolkit from http://AjaxControlToolkit.CodePlex.com or you can install the Ajax Control Toolkit directly within Visual Studio by executing the following NuGet command: The New jQuery Extender Base Class This release of the Ajax Control Toolkit introduces a new jQueryExtender base class. This new base class enables you to create Ajax Control Toolkit controls with jQuery instead of the Microsoft Ajax Library. Currently, only one control in the Ajax Control Toolkit has been rewritten to use the new jQueryExtender base class (only one control has been jQueryized). The ToggleButton control is the first of the Ajax Control Toolkit controls to undergo this dramatic transformation. All of the other controls in the Ajax Control Toolkit are written using the Microsoft Ajax Library. We hope to gradually rewrite these controls as jQuery controls over time. You can view the new jQuery ToggleButton live at the Ajax Control Toolkit sample site: http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/ToggleButton/ToggleButton.aspx Why are we rewriting Ajax Control Toolkits with jQuery? There are very few developers actively working with the Microsoft Ajax Library while there are thousands of developers actively working with jQuery. Because we want talented developers in the community to continue to contribute to the Ajax Control Toolkit, and because almost all JavaScript developers are familiar with jQuery, it makes sense to support jQuery with the Ajax Control Toolkit. Also, we believe that the Ajax Control Toolkit is a great framework for Web Forms developers who want to build new ASP.NET controls that use JavaScript. The Ajax Control Toolkit has great features such as automatic bundling, minification, caching, and compression. We want to make it easy for ASP.NET developers to build new controls that take advantage of these features. Instantiating Controls with data-* Attributes We took advantage of the new JQueryExtender base class to change the way that Ajax Control Toolkit controls are instantiated. In the past, adding an Ajax Control Toolkit to a page resulted in inline JavaScript being injected into the page. For example, adding the ToggleButton control to a page injected the following HTML and script: <input id="ctl00_SampleContent_CheckBox1" name="ctl00$SampleContent$CheckBox1" type="checkbox" checked="checked" /> <script type="text/javascript"> //<![CDATA[ Sys.Application.add_init(function() { $create(Sys.Extended.UI.ToggleButtonBehavior, {"CheckedImageAlternateText":"Check", "CheckedImageUrl":"ToggleButton_Checked.gif", "ImageHeight":19, "ImageWidth":19, "UncheckedImageAlternateText":"UnCheck", "UncheckedImageUrl":"ToggleButton_Unchecked.gif", "id":"ctl00_SampleContent_ToggleButtonExtender1"}, null, null, $get("ctl00_SampleContent_CheckBox1")); }); //]]> </script> Notice the call to the JavaScript $create() method at the bottom of the page. When using the Microsoft Ajax Library, this call to the $create() method is necessary to create the Ajax Control Toolkit control. This inline script looks pretty ugly to a modern JavaScript developer. Inline script! Horrible! The jQuery version of the ToggleButton injects the following HTML and script into the page: <input id="ctl00_SampleContent_CheckBox1" name="ctl00$SampleContent$CheckBox1" type="checkbox" checked="checked" data-act-togglebuttonextender="imageWidth:19, imageHeight:19, uncheckedImageUrl:'ToggleButton_Unchecked.gif', checkedImageUrl:'ToggleButton_Checked.gif', uncheckedImageAlternateText:'I don&#39;t understand why you don&#39;t like ASP.NET', checkedImageAlternateText:'It&#39;s really nice to hear from you that you like ASP.NET'" /> Notice that there is no script! There is no call to the $create() method. In fact, there is no inline JavaScript at all. The jQuery version of the ToggleButton uses an HTML5 data-* attribute instead of an inline script. The ToggleButton control is instantiated with a data-act-togglebuttonextender attribute. Using data-* attributes results in much cleaner markup (You don’t need to feel embarrassed when selecting View Source in your browser). Ajax Control Toolkit versus jQuery So in a jQuery world why is the Ajax Control Toolkit needed at all? Why not just use jQuery plugins instead of the Ajax Control Toolkit? For example, there are lots of jQuery ToggleButton plugins floating around the Internet. Why not just use one of these jQuery plugins instead of using the Ajax Control Toolkit ToggleButton control? There are three main reasons why the Ajax Control Toolkit continues to be valuable in a jQuery world: Ajax Control Toolkit controls run on both the server and client jQuery plugins are client only. A jQuery plugin does not include any server-side code. If you need to perform any work on the server – think of the AjaxFileUpload control – then you can’t use a pure jQuery solution. Ajax Control Toolkit controls provide a better Visual Studio experience You don’t get any design time experience when you use jQuery plugins within Visual Studio. Ajax Control Toolkit controls, on the other hand, are designed to work with Visual Studio. For example, you can use the Visual Studio Properties window to set Ajax Control Toolkit control properties. Ajax Control Toolkit controls shield you from working with JavaScript I like writing code in JavaScript. However, not all developers like JavaScript and some developers want to completely avoid writing any JavaScript code at all. The Ajax Control Toolkit enables you to take advantage of JavaScript (and the latest features of HTML5) in your ASP.NET Web Forms websites without writing a single line of JavaScript. Better ToolkitScriptManager Documentation With this release, we have added more detailed documentation for using the ToolkitScriptManager. In particular, we added documentation that describes how to take advantage of the new bundling, minification, compression, and caching features of the Ajax Control Toolkit. The ToolkitScriptManager documentation is part of the Ajax Control Toolkit sample site and it can be read here: http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/ToolkitScriptManager/ToolkitScriptManager.aspx Other Fixes This release of the Ajax Control Toolkit includes several important bug fixes. For example, the Ajax Control Toolkit Twitter control was completely rewritten with this release. Twitter is in the process of retiring the first version of their API. You can read about their plans here: https://dev.twitter.com/blog/planning-for-api-v1-retirement We completely rewrote the Ajax Control Toolkit Twitter control to use the new Twitter API. To take advantage of the new Twitter API, you must get a key and access token from Twitter and add the key and token to your web.config file. Detailed instructions for using the new version of the Ajax Control Toolkit Twitter control can be found here: http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/Twitter/Twitter.aspx   Summary We’ve made some really great changes to the Ajax Control Toolkit over the last two releases to modernize the toolkit. In the previous release, we updated the Ajax Control Toolkit to use a better bundling, minification, compression, and caching system. With this release, we updated the Ajax Control Toolkit to support jQuery. We also continue to update the Ajax Control Toolkit with important bug fixes. I hope you like these changes and I look forward to hearing your feedback.

  • VS 2010 SP1 (Beta) and IIS Express

    - by ScottGu
    Last month we released the VS 2010 Service Pack 1 (SP1) Beta.  You can learn more about the VS 2010 SP1 Beta from Jason Zander’s two blog posts about it, and from Scott Hanselman’s blog post that covers some of the new capabilities enabled with it.  You can download and install the VS 2010 SP1 Beta here. IIS Express Earlier this summer I blogged about IIS Express.  IIS Express is a free version of IIS 7.5 that is optimized for developer scenarios.  We think it combines the ease of use of the ASP.NET Web Server (aka Cassini) currently built-into VS today with the full power of IIS.  Specifically: It’s lightweight and easy to install (less than 5Mb download and a quick install) It does not require an administrator account to run/debug applications from Visual Studio It enables a full web-server feature set – including SSL, URL Rewrite, and other IIS 7.x modules It supports and enables the same extensibility model and web.config file settings that IIS 7.x support It can be installed side-by-side with the full IIS web server as well as the ASP.NET Development Server (they do not conflict at all) It works on Windows XP and higher operating systems – giving you a full IIS 7.x developer feature-set on all Windows OS platforms IIS Express (like the ASP.NET Development Server) can be quickly launched to run a site from a directory on disk.  It does not require any registration/configuration steps. This makes it really easy to launch and run for development scenarios. Visual Studio 2010 SP1 adds support for IIS Express – and you can start to take advantage of this starting with last month’s VS 2010 SP1 Beta release. Downloading and Installing IIS Express IIS Express isn’t included as part of the VS 2010 SP1 Beta.  Instead it is a separate ~4MB download which you can download and install using this link (it uses WebPI to install it).  Once IIS Express is installed, VS 2010 SP1 will enable some additional IIS Express commands and dialog options that allow you to easily use it. Enabling IIS Express for Existing Projects Visual Studio today defaults to using the built-in ASP.NET Development Server (aka Cassini) when running ASP.NET Projects: Converting your existing projects to use IIS Express is really easy.  You can do this by opening up the project properties dialog of an existing project, and then by clicking the “web” tab within it and selecting the “Use IIS Express” checkbox. Or even simpler, just right-click on your existing project, and select the “Use IIS Express…” menu command: And now when you run or debug your project you’ll see that IIS Express now starts up and runs automatically as your web-server: You can optionally right-click on the IIS Express icon within your system tray to see/browse all of sites and applications running on it: Note that if you ever want to revert back to using the ASP.NET Development Server you can do this by right-clicking the project again and then select the “Use Visual Studio Development Server” option (or go into the project properties, click the web tab, and uncheck IIS Express).  This will revert back to the ASP.NET Development Server the next time you run the project. IIS Express Properties Visual Studio 2010 SP1 exposes several new IIS Express configuration options that you couldn’t previously set with the ASP.NET Development Server.  Some of these are exposed via the property grid of your project (select the project node in the solution explorer and then change them via the property window): For example, enabling something like SSL support (which is not possible with the ASP.NET Development Server) can now be done simply by changing the “SSL Enabled” property to “True”: Once this is done IIS Express will expose both an HTTP and HTTPS endpoint for the project that we can use: SSL Self Signed Certs IIS Express ships with a self-signed SSL cert that it installs as part of setup – which removes the need for you to install your own certificate to use SSL during development.  Once you change the above drop-down to enable SSL, you’ll be able to browse to your site with the appropriate https:// URL prefix and it will connect via SSL. One caveat with self-signed certificates, though, is that browsers (like IE) will go out of their way to warn you that they aren’t to be trusted: You can mark the certificate as trusted to avoid seeing dialogs like this – or just keep the certificate un-trusted and press the “continue” button when the browser warns you not to trust your local web server. Additional IIS Settings IIS Express uses its own per-user ApplicationHost.config file to configure default server behavior.  Because it is per-user, it can be configured by developers who do not have admin credentials – unlike the full IIS.  You can customize all IIS features and settings via it if you want ultimate server customization (for example: to use your own certificates for SSL instead of self-signed ones). We recommend storing all app specific settings for IIS and ASP.NET within the web.config file which is part of your project – since that makes deploying apps easier (since the settings can be copied with the application content).  IIS (since IIS 7) no longer uses the metabase, and instead uses the same web.config configuration files that ASP.NET has always supported – which makes xcopy/ftp based deployment much easier. Making IIS Express your Default Web Server Above we looked at how we can convert existing sites that use the ASP.NET Developer Web Server to instead use IIS Express.  You can configure Visual Studio to use IIS Express as the default web server for all new projects by clicking the Tools->Options menu  command and opening up the Projects and Solutions->Web Projects node with the Options dialog: Clicking the “Use IIS Express for new file-based web site and projects” checkbox will cause Visual Studio to use it for all new web site and projects. Summary We think IIS Express makes it even easier to build, run and test web applications.  It works with all versions of ASP.NET and supports all ASP.NET application types (including obviously both ASP.NET Web Forms and ASP.NET MVC applications).  Because IIS Express is based on the IIS 7.5 codebase, you have a full web-server feature-set that you can use.  This means you can build and run your applications just like they’ll work on a real production web-server.  In addition to supporting ASP.NET, IIS Express also supports Classic ASP and other file-types and extensions supported by IIS – which also makes it ideal for sites that combine a variety of different technologies. Best of all – you do not need to change any code to take advantage of it.  As you can see above, updating existing Visual Studio web projects to use it is trivial.  You can begin to take advantage of IIS Express today using the VS 2010 SP1 Beta. Hope this helps, Scott
