  • C# creating a custom user interface

    - by CSharpInquisitor
    Hi, I have a SQL database holding a number of numeric and text values that get updated regularly. The exact number/type/names of these data points can change depending on the source of the database writes. I would like to create a user interface editor, where the user can add database points to the UI and arrange them and format them as they want. If a new point is added to the database they can right click on the UI and say "add this point" and choose from a list of database points. I'm looking for some pointers on where to start on creating this editor application, could something clever be done using XAML to dynamically create std WPF controls at runtime? Thanks in advance for any help, Si

  • Custom spring bean

    - by Hari
    Hi, I want to convert some of our internal API into a spring bean that we can use in other projects. This API needs some instantiation and other logic which I want to encapsulate in this bean so that we can just put the bean into our app context with necessary propoerties alone. I remember having read an article on this somewhere in the past - but cant find it now. Any pointers to something similar will be helpful

  • possible to create custom scrollbar graphics without flash?

    - by Joel
    A friend is wanting me to help her convert her flash based website to html. She has an embedded textbox with a scrollbar that is using a flower instead of a normal scrollbar. Avoiding the obvious question of why a user would want a non-standard element to do this task, is it possible to do this without flash?

  • Custom Floating Point Representation

    - by Abion47
    I'm trying to write a parser that will read a particular file type, and I need to map the different data types to C# equivalents. Most of them aren't that difficult, but I'm having trouble wrapping my head around what "int16 with a bias of 14" means. I've deduced that it's some kind of floating point type, so my best bet would be to write a converter that would map it to a float, double, or decimal type. I'm not sure where to take it from here, though.

  • Handling Trailing Delimiters in HL7 Messages

    - by Thomas Canter
    Applies to: BizTalk Server 2006 with the HL7 1.3 Accelerator Outline of the problem Trailing Delimiters are empty values at the end of an object in a HL7 ER7 formatted message. Examples: Empty Field NTE|P| NTE|P|| Empty component ORC|1|725^ Empty Subcomponent ORC|1|||||27& Empty repeat OBR|1||||||||027~ Trailing delimiters indicate the following object exists and is empty, which is quite different from null, null is an explicit value indicated by a pair of double quotes -> "". The BizTalk HL7 Accelerator by default does not allow trailing delimiters. There are three methods to allow trailing delimiters. NOTE: All Schemas always allow trailing delimiters in the MSH Segment Using party identifiers MSH3.1 – Receive/inbound processing, using this value as a party allows you to configure the system to allow inbound trailing delimiters. MSH5.1 – Send/outbound processing, using this value as a party allows you to configure the system to allow outbound trailing delimiters. Generally, if you allow inbound trailing delimiters, unless you are willing to programmatically remove all trailing delimiters, then you need to configure the send to allow trailing delimiters. Add the appropriate parties to the BizTalk Parties list from these two fields in your message stream. Open the BizTalk HL7 Configuration tool and for each party check the "Allow trailing delimiters (separators)" check box on the Validation tab. Disadvantage – Each MSH3.1 and MSH5.1 value must be represented in the parties list and configured. Advantage – granular control over system behavior for each inbound/outbound system. Using instance properties of a pipeline used in a send port or receive location. Open the BizTalk Server Administration console locate the send port or receive location that contains the BTAHL72XReceivePipeline or BTAHL72XSendPipeline pipeline. Open the properties To the right of the pipeline selected locate the […] ellipses button In the property list, locate the "TrailingDelimiterAllowed" property and set it to True. Advantage – All messages through a particular Send Port or Receive Location will allow trailing delimiters. Disadvantage – Must configure each Send Port or Receive Location. No granular control over which remote parties will send or receive messages with trailing delimiters. Using a custom pipeline that uses a pre-configured BTA HL7 Pipeline component. Use Visual Studio to construct a custom receive and send pipeline using the appropriate assembler or dissasembler. Set the component property to "TrailingDelimitersAllowed" to True Compile and deploy the custom pipeline Use the custom pipeline instead of the standard pipeline for all HL7 message processing Advantage – All messages using the custom pipeline will automatically allow trailing delimiters. Disadvantage – Requires custom coding and development to create and deploy the custom pipeline. No granular control over which remote parties will send or receive messages with trailing delimiters. What does a Trailing Delimiter do to the XML Schema? Allowing trailing delimiters does not have the impact often expected in the actual XML Schema.The Schema reproduces the message with no data loss.Thus, the message when represented in XML must contain the extra fields, in order to reproduce the outbound message.Thus, a trialing delimiter results in an empty XML field.Trailing Delmiters are not stripped from the inbound message. Example:<PID_21>44172</PID_21><PID_21>9257</PID_21> -> the original maximum number of repeats<PID_21></PID_21> -> The empty repeated field Allowing trailing delimiters not remove the trailing delimiters from the message, it simply suppresses the check that will cause the message to fail parse with trailing delimiters. When can you not fix the problem by enabling trailing delimiters Each object in a message must have a location in the target BTAHL7 schema for its content to reside.If you have more objects in the message than are contained at that location, then enabling trailing delimiters will not resolve the problem. The schema must be extended to accommodate the empty message content.Examples: Extra Field NTE|P||||Only 4 fields in NTE Segment, the 4th field exists, but is empty. Extra component PID|1|1523|47^^^^^^^Only 5 components in a CX data type, the 5th component exists, but is empty Extra subcomponent ORC|1|||||27&&Only 2 subcomponents in a CQ data type, the 3rd subcomponent is empty, but exists. Extra Repeat PID|1||||||||||||||||||||4419~5217~Only 2 repeats allowed for the field "Mother's identifier", the repeat is empty, but exists. In each of these cases, you must locate the failing object and extend the type to allow an additional object of that type. FieldAdd a field of ST to the end of the segment with a suitable name in the segments_nnn.xsd Component Create a new Custom CX data type (i.e. CX_XtraComp) in the datatypes_nnn.xsd and add a new component to the custom CX data type. Update the field in the segments_nnn.xsd file to use the custom data type instead of the standard datatype. Subcomponent Create a new Custom CQ data type that accepts an additional TS value at the end of the data type. Create a custom TQ data type that uses the new custom CQ data type as the first subcomponent. Modify the ORC segment to use the new CQ data type at ORC.7 instead of the standard CQ data type. RepeatModify the Field definition for PID.21 in the segments_nnn.xsd to allow more repeats in the field.

  • what should a developer know/address to build commercial Android Apps ?

    - by giulio
    Android and mobile development is an exciting area of development. As it is a new discipline, what would be expected of an android developer to build commercially robust applications in terms of skills ? The problem that I and, i think, many other "noobs" into the technology would like to know are the areas of technical skills and the progression to the required advanced topics that goes beyond the the very basics provided by Google. There is a lot of information that's quite useful but its not organised into categories of discipline nor order.

  • Hudson deploy specific git revision

    - by brad
    I'm using hudson to auto-deploy my Rails app to heroku. In my main build job I pull from a Git repo (hosted using gitosis on the same machine), master branch with the following: URL of repository: /home/git/repositories/my_app.git Name of repository: origin Refspec: +refs/heads/master:refs/remotes/origin/master Branches to build: master Then, assuming all tests pass, I want to kick off a new build that is the deploy to Heroku. I can't however figure out how to get that deploy build to checkout the particular revision that this build was using. I understand there's a parameterized trigger plugin that would allow me to pass this revision number, but I don't know how I can tell hudson to checkout this particular revision on the deploy build. I'm pretty sure this just has to do with my limited knowledge of git, but where in the hudson git config's is there an option to checkout a particular revision? Otherwise, I could have many commits happen whilst a build is happening, and when it kicks off a deploy build, that deploy build would just check out the HEAD of the branch, which may not be the same as the code that was pushed that triggered this build. I don't fully understand why I have a refspec in Hudson, then also specify a branch to build, I thought this was the same thing. Can refspec somehow specify the revision number? How would this be referenced if it was passed through with the parameterized trigger plugin? (I've never used that plugin, but someone else recommended it as a way to pass in vars to a new build, if there's another way I'm all ears)

  • The HTG Guide to Using a Bluetooth Keyboard with Your Android Device

    - by Matt Klein
    Android devices aren’t usually associated with physical keyboards. But, since Google is now bundling their QuickOffice app with the newly-released Kit-Kat, it appears inevitable that at least some Android tablets (particularly 10-inch models) will take on more productivity roles. In recent years, physical keyboards have been rendered obsolete by swipe style input methods such as Swype and Google Keyboard. Physical keyboards tend to make phones thick and plump, and that won’t fly today when thin (and even flexible and curved) is in vogue. So, you’ll be hard-pressed to find smartphone manufacturers launching new models with physical keyboards, thus rendering sliders to a past chapter in mobile phone evolution. It makes sense to ditch the clunky keyboard phone in favor of a lighter, thinner model. You’re going to carry around in your pocket or purse all day, why have that extra bulk and weight? That said, there is sound logic behind pairing tablets with keyboards. Microsoft continues to plod forward with its Surface models, and while critics continue to lavish praise on the iPad, its functionality is obviously enhanced and extended when you add a physical keyboard. Apple even has an entire page devoted specifically to iPad-compatible keyboards. But an Android tablet and a keyboard? Does such a thing even exist? They do actually. There are docking keyboards and keyboard/case combinations, there’s the Asus Transformer family, Logitech markets a Windows 8 keyboard that speaks “Android”, and these are just to name a few. So we know that keyboard products that are designed to work with Android exist, but what about an everyday Bluetooth keyboard you might use with Windows or OS X? How-To Geek wanted look at how viable it is to use such a keyboard with Android. We conducted some research and examined some lists of Android keyboard shortcuts. Most of what we found was long outdated. Many of the shortcuts don’t even apply anymore, while others just didn’t work. Regardless, after a little experimentation and a dash of customization, it turns out using a keyboard with Android is kind of fun, and who knows, maybe it will catch on. Setting things up Setting up a Bluetooth keyboard with Android is very easy. First, you’ll need a Bluetooth keyboard and of course an Android device, preferably running version 4.1 (Jelly Bean) or higher. For our test, we paired a second-generation Google Nexus 7 running Android 4.3 with a Samsung Series 7 keyboard. In Android, enable Bluetooth if it isn’t already on. We’d like to note that if you don’t normally use Bluetooth accessories and peripherals with your Android device (or any device really), it’s best practice to leave Bluetooth off because, like GPS, it drains the device’s battery more quickly. To enable Bluetooth, simply go to “Settings” -> “Bluetooth” and tap the slider button to “On”. To set up the keyboard, make sure it is on and then tap “Bluetooth” in the Android settings. On the resulting screen, your Android device should automatically search for and hopefully find your keyboard. If you don’t get it right the first time, simply turn the keyboard on again and then tap “Search for Devices” to try again. If it still doesn’t work, make sure you have fresh batteries and the keyboard isn’t paired to another device. If it is, you will need to unpair it before it will work with your Android device (consult your keyboard manufacturer’s documentation or Google if you don’t know how to do this). When Android finds your keyboard, select it under “Available Devices” … … and you should be prompted to type in a code: If successful, you will see that device is now “Connected” and you’re ready to go. If you want to test things out, try pressing the “Windows” key (“Apple” or “Command”) + ESC, and you will be whisked to your Home screen. So, what can you do? Traditional Mac and Windows users know there’s usually a keyboard shortcut for just about everything (and if there isn’t, there’s all kinds of ways to remap keys to do a variety of commands, tasks, and functions). So where does Android fall in terms of baked-in keyboard commands? There answer to that is kind of enough, but not too much. There are definitely established combos you can use to get around, but they aren’t clear and there doesn’t appear to be any one authority on what they are. Still, there is enough keyboard functionality in Android to make it a viable option, if only for those times when you need to get something done (long e-mail or important document) and an on-screen keyboard simply won’t do. It’s important to remember that Android is, and likely always will be a touch-first interface. That said, it does make some concessions to physical keyboards. In other words, you can get around Android fairly well without having to lift your hands off the keys, but you will still have to tap the screen regularly, unless you add a mouse. For example, you can wake your device by tapping a key rather than pressing its power button. However, if your device is slide or pattern-locked, then you’ll have to use the touchscreen to unlock it – a password or PIN however, works seamlessly with a keyboard – other things like widgets and app controls and features, have to be tapped. You get the idea. Keyboard shortcuts and navigation As we said, baked-in keyboard shortcut combos aren’t necessarily abundant nor apparent. The one thing you can always do is search. Any time you want to Google something, start typing from the Home screen and the search screen will automatically open and begin displaying results. Other than that, here is what we were able to figure out: ESC = go back CTRL + ESC = menu CTRL + ALT + DEL = restart (no questions asked) ALT + SPACE = search page (say “OK Google” to voice search) ALT + TAB (ALT + SHIFT + TAB) = switch tasks Also, if you have designated volume function keys, those will probably work too. There’s also some dedicated app shortcuts like calculator, Gmail, and a few others: CMD + A = calculator CMD + C = contacts CMD + E = e-mail CMD + G = Gmail CMD + L = Calendar CMD + P = Play Music CMD + Y = YouTube Overall, it’s not a long comprehensive list and there’s no dedicated keyboard combos for the full array of Google’s products. Granted, it’s hard to imagine getting a lot of mileage out of a keyboard with Maps but with something like Keep, you could type out long, detailed lists on your tablet, and then view them on your smartphone when you go out shopping. You can also use the arrow keys to navigate your Home screen over shortcuts and open the app drawer. When something on the screen is selected, it will be highlighted in blue. Press “Enter” to open your selection. Additionally, if an app has its own set of shortcuts, e.g. Gmail has quite a few unique shortcuts to it, as does Chrome, some – though not many – will work in Android (not for YouTube though). Also, many “universal” shortcuts such as Copy (CTRL + C), Cut (CTRL + X), Paste (CTRL + V), and Select All (CTRL + A) work where needed – such as in instant messaging, e-mail, social media apps, etc. Creating custom application shortcuts What about custom shortcuts? When we were researching this article, we were under the impression that it was possible to assign keyboard combinations to specific apps, such as you could do on older Android versions such as Gingerbread. This no long seems to be the case and nowhere in “Settings” could we find a way to assign hotkey combos to any of our favorite, oft-used apps or functions. If you do want custom keyboard shortcuts, what can you do? Luckily, there’s an app on Google Play that allows you to, among other things, create custom app shortcuts. It is called External Keyboard Helper (EKH) and while there is a free demo version, the pay version is only a few bucks. We decided to give EKH a whirl and through a little experimentation and finally reading the developer’s how-to, we found we could map custom keyboard combos to just about anything. To do this, first open the application and you’ll see the main app screen. Don’t worry about choosing a custom layout or anything like that, you want to go straight to the “Advanced settings”: In the “Advanced settings” select “Application shortcuts” to continue: You can have up to 16 custom application shortcuts. We are going to create a custom shortcut to the Facebook app. We choose “A0”, and from the resulting list, Facebook. You can do this for any number of apps, services, and settings. As you can now see, the Facebook app has now been linked to application-zero (A0): Go back to the “Advanced settings” and choose “Customize keyboard mappings”: You will be prompted to create a custom keyboard layout so we choose “Custom 1”: When you choose to create a custom layout, you can do a great many more things with your keyboard. For example, many keyboards have predefined function (Fn) keys, which you can map to your tablet’s brightness controls, toggle WiFi on/off, and much more. A word of advice, the application automatically remaps certain keys when you create a custom layout. This might mess up some existing keyboard combos. If you simply want to add some functionality to your keyboard, you can go ahead and delete EKH’s default changes and start your custom layout from scratch. To create a new combo, select “Add new key mapping”: For our new shortcut, we are going to assign the Facebook app to open when we key in “ALT + F”. To do this, we press the “F” key while in the “Scancode” field and we see it returns a value of “33”. If we wanted to use a different key, we can press “Change” and scan another key’s numerical value. We now want to assign the “ALT” key to application “A0”, previously designated as the Facebook app. In the “AltGr” field, we enter “A0” and then “Save” our custom combo. And now we see our new application shortcut. Now, as long as we’re using our custom layout, every time we press “ALT + F”, the Facebook app will launch: External Keyboard Helper extends far beyond simple application shortcuts and if you are looking for deeper keyboard customization options, you should definitely check it out. Among other things, EKH also supports dozens of languages, allows you to quickly switch between layouts using a key or combo, add up to 16 custom text shortcuts, and much more! It can be had on Google Play for $2.53 for the full version, but you can try the demo version for free. More extensive documentation on how to use the app is also available. Android? Keyboard? Sure, why not? Unlike traditional desktop operating systems, you don’t need a physical keyboard and mouse to use a mobile operating system. You can buy an iPad or Nexus 10 or Galaxy Note, and never need another accessory or peripheral – they work as intended right out of the box. It’s even possible you can write the next great American novel on one these devices, though that might require a lot of practice and patience. That said, using a keyboard with Android is kind of fun. It’s not revelatory but it does elevate the experience. You don’t even need to add customizations (though they are nice) because there are enough existing keyboard shortcuts in Android to make it usable. Plus, when it comes to inputting text such as in an editor or terminal application, we fully advocate big, physical keyboards. Bottom line, if you’re looking for a way to enhance your Android tablet, give a keyboard a chance. Do you use your Android device for productivity? Is a physical keyboard an important part of your setup? Do you have any shortcuts that we missed? Sound off in the comments and let us know what you think.

  • How do I create statistics to make ‘small’ objects appear ‘large’ to the Optmizer?

    - by Maria Colgan
    I recently spoke with a customer who has a development environment that is a tiny fraction of the size of their production environment. His team has been tasked with identifying problem SQL statements in this development environment before new code is released into production. The problem is the objects in the development environment are so small, the execution plans selected in the development environment rarely reflects what actually happens in production. To ensure the development environment accurately reflects production, in the eyes of the Optimizer, the statistics used in the development environment must be the same as the statistics used in production. This can be achieved by exporting the statistics from production and import them into the development environment. Even though the underlying objects are a fraction of the size of production, the Optimizer will see them as the same size and treat them the same way as it would in production. Below are the necessary steps to achieve this in their environment. I am using the SH sample schema as the application schema who's statistics we want to move from production to development. Step 1. Create a staging table, in the production environment, where the statistics can be stored Step 2. Export the statistics for the application schema, from the data dictionary in production, into the staging table Step 3. Create an Oracle directory on the production system where the export of the staging table will reside and grant the SH user the necessary privileges on it. Step 4. Export the staging table from production using data pump export Step 5. Copy the dump file containing the stating table from production to development Step 6. Create an Oracle directory on the development system where the export of the staging table resides and grant the SH user the necessary privileges on it.  Step 7. Import the staging table into the development environment using data pump import Step 8. Import the statistics from the staging table into the dictionary in the development environment. You can get a copy of the script I used to generate this post here. +Maria Colgan

I created a new Team Project in TFS 2010 Beta 1 and choose not to configure SharePoint during the creation of the Team Project. Of course I found out fairly quickly that a portal for TFS is very useful, especially the Iteration and the Product backlog workbooks and the dashboard reports. This blog describes how you can configure the sharepoint portal afterwards. Update: September 9th, 2009 Adding the portal afterwards is much easier as described below. Here are the steps Step 1: Create a new temporary project (with a SharePoint site for it). Open the Team Explorer Right click in the Team Explorer the root node (i.e. the project collection) Select "New team project" from the menu Walk throught he wizard and make sure you check the option to create the portal (which is by default checked) Step 2: Disable the site for the new project Open the Team Explorer Select the team project you created in step 1 In the menu click on Team -> Show Project Portal. In the menu click on Team -> Team Project Settings -> Portal Settings... The following dialog pops up Uncheck the option "Enable team project portal" Confirm the dialog with OK Step 3: Enable the site for the original one. Point it to the newly created site. Open the Team Explorer Select the team project you want to add the portal to In the menu open Team -> Team Project Settings -> Portal Settings... The same dialog as in step 2 pops up Check the option "Enable team project portal" Click on the "Configure URL" button The following dialog pops up   In the dialog select in the combobox of the web application the TFS server Enter in the Relative site path the text "sites/[Project Collection Name]/[Team Project Name created in step 1]" Confirm the "Specify an existing SharePoint Site" with OK Check the "Reports and dashboards refer to data for this team project" option Confirm the dialog "Project Portal Settings" with OK Step 4: Delete the temporary project you created. In Beta 1, I have found no way to delete a team project. Maybe it will be available in TFS 2010 Beta 2. Original post Step 1: Create new portal site Go to the sharepoint site of your project collection (/sites//default.aspx">/sites//default.aspx">http://<servername>/sites/<project_collection_name>/default.aspx) Click on the Site Actions at the left side of the screen and choose the option Site Settings In the site settings, choose the Sites and workspaces option Create a new site Enter the values for the Title, the description, the site address. And choose for the TFS2010 Agile Dashboard as template. Create the site, by clicking on the Create button Step 2: Integrate portal site with team project Open Visual Studio Open the Team Explorer (View -> Team Explorer) Select in the Team Explorer tool window the Team Project for which you are create a new portal Open the Project Portal Settings (Team -> Team Project Settings -> Portal Setings...) Check the Enable team project portal checkbox Click on Configure URL... You will get a new dialog as below Enter the url to the TFS server in the web application combobox And specify the relative site path: sites/<project collection>/<site name> Confirm with OK Check in the Project Portal Settings dialog the checkbox "Reports and dashboards refer to data for this team project" Confirm the settings with OK (this takes a while...) When you now browse to the portal, you will see that the dashboards are now showing up with the data for the current team project. Step 3: Download process template To get a copy of the documents that are default in a team project, we need to have a fresh set of files that are not attached to a team project yet. You can do that with the following steps. Start the Process Template Manager (Team -> Team Project Collection Settings -> Process Template Manager...) Choose the Agile process template and click on download Choose a folder to download Step 4: Add Product and Iteration backlog Go to the Team Explorer in Visual Studio Make sure the team project is in the list of team projects, and expand the team project Right click the Documents node, and choose New Document Library Enter "Shared Documents", and click on Add Right click the Shared Documents node and choose Upload Document Go the the file location where you stored the process template from step 3 and then navigate to the subdirectory "Agile Process Template 5.0\MSF for Agile Software Development v5.0\Windows SharePoint Services\Shared Documents\Project Management" Select in the Open Dialog the files "Iteration Backlog" and "Product Backlog", and click Open Step 5: Bind Iteration backlog workbook to the team project Right click on the "Iteration Backlog" file and select Edit, and confirm any warning messages Place your cursor in cell A1 of the Iteration backlog worksheet Switch to the Team ribbon and click New List. Select your Team Project and click Connect From the New List dialog, select the Iteration Backlog query in the Workbook Queries folder. The final step is to add a set of document properties that allow the workbook to communicate with the TFS reporting warehouse. Before we create the properties we need to collect some information about your project. The first piece of information comes from the table created in the previous step.  As you collect these properties, copy them into notepad so they can be used in later steps. Property How to retrieve the value? [Table name] Switch to the Design ribbon and select the Table Name value in the Properties portion of the ribbon [Project GUID] In the Visual Studio Team Explorer, right click your Team Project and select Properties.  Select the URL value and copy the GUID (long value with lots of characters) at the end of the URL [Team Project name] In the Properties dialog, select the Name field and copy the value [TFS server name] In the Properties dialog, select the Server Name field and copy the value [UPDATE] I have found that this is not correct: you need to specify the instance of your SQL Server. The value is used to create a connection to the TFS cube. Switch back to the Iteration Backlog workbook. Click the Office button and select Prepare – Properties. Click the Document Properties – Server drop down and select Advanced Properties. Switch to the Custom tab and add the following properties using the values you collected above. Variable name Value [Table name]_ASServerName [TFS server name] [Table name]_ASDatabase tfs_warehouse [Table name]_TeamProjectName [Team Project name] [Table name]_TeamProjectId [Project GUID] Click OK to close the properties dialog. It is possible that the Estimated Work (Hours) is showing the #REF! value. To resolve that change the formula with: =SUMIFS([Table name][Original Estimate]; [Table name][Iteration Path];CurrentIteration&"*";[Table name][Area Path];AreaPath&"*";[Table name][Work Item Type]; "Task") For example =SUMIFS(VSTS_ab392b55_6647_439a_bae4_8c66e908bc0d[Original Estimate]; VSTS_ab392b55_6647_439a_bae4_8c66e908bc0d[Iteration Path];CurrentIteration&"*";VSTS_ab392b55_6647_439a_bae4_8c66e908bc0d[Area Path];AreaPath&"*";VSTS_ab392b55_6647_439a_bae4_8c66e908bc0d[Work Item Type]; "Task") Also the Total Remaining Work in the Individual Capacity table may contain #REF! values. To resolve that change the formula with: =SUMIFS([Table name][Remaining Work]; [Table name][Iteration Path];CurrentIteration&"*";[Table name][Area Path];AreaPath&"*";[Table name][Assigned To];[Team Member];[Table name][Work Item Type]; "Task") For example =SUMIFS(VSTS_ab392b55_6647_439a_bae4_8c66e908bc0d[Remaining Work]; VSTS_ab392b55_6647_439a_bae4_8c66e908bc0d[Iteration Path];CurrentIteration&"*";VSTS_ab392b55_6647_439a_bae4_8c66e908bc0d[Area Path];AreaPath&"*";VSTS_ab392b55_6647_439a_bae4_8c66e908bc0d[Assigned To];[Team Member];VSTS_ab392b55_6647_439a_bae4_8c66e908bc0d[Work Item Type]; "Task") Save and close the workbook. Step 6: Bind Product backlog workbook to the team project Repeat the steps for binding the Iteration backlog for thiw workbook too. In the worksheet Capacity, the formula of the Storypoints might be missing. You can resolve it with: =IF([Iteration]="";"";SUMIFS([Table name][Story Points];[Table name][Iteration Path];[Iteration]&"*")) Example =IF([Iteration]="";"";SUMIFS(VSTS_487f1e4c_db30_4302_b5e8_bd80195bc2ec[Story Points];VSTS_487f1e4c_db30_4302_b5e8_bd80195bc2ec[Iteration Path];[Iteration]&"*"))
