  • Windows 7 Phone Database Rapid Repository – V2.0 Beta Released

    - by SeanMcAlinden
    Hi All, A V2.0 beta has been released for the Windows 7 Phone database Rapid Repository, this can be downloaded at the following: http://rapidrepository.codeplex.com/ Along with the new View feature which greatly enhances querying and performance, various bugs have been fixed including a more serious bug with the caching that caused the GetAll() method to sometimes return inconsistent results (I’m a little bit embarrased by this bug). If you are currently using V1.0 in development, I would recommend swapping in the beta immediately. A full release will be available very shortly, I just need a few more days of testing and some input from other users/testers.   *Breaking Changes* The only real change is the RapidContext has moved under the main RapidRepository namespace. Various internal methods have been actually made ‘internal’ and replaced with a more friendly API (I imagine not many users will notice this change). Hope you like it Kind Regards, Sean McAlinden

  • Windows 7 Phone Database – Querying with Views and Filters

    - by SeanMcAlinden
    I’ve just added a feature to Rapid Repository to greatly improve how the Windows 7 Phone Database is queried for performance (This is in the trunk not in Release V1.0). The main concept behind it is to create a View Model class which would have only the minimum data you need for a page. This View Model is then stored and retrieved rather than the whole list of entities. Another feature of the views is that they can be pre-filtered to even further improve performance when querying. You can download the source from the Microsoft Codeplex site http://rapidrepository.codeplex.com/. Setting up a view Lets say you have an entity that stores lots of data about a game result for example: GameScore entity public class GameScore : IRapidEntity {     public Guid Id { get; set; }     public string GamerId {get;set;}     public string Name { get; set; }     public Double Score { get; set; }     public Byte[] ThumbnailAvatar { get; set; }     public DateTime DateAdded { get; set; } }   On your page you want to display a list of scores but you only want to display the score and the date added, you create a View Model for displaying just those properties. GameScoreView public class GameScoreView : IRapidView {     public Guid Id { get; set; }     public Double Score { get; set; }     public DateTime DateAdded { get; set; } }   Now you have the view model, the first thing to do is set up the view at application start up. This is done using the following syntax. View Setup public MainPage() {     RapidRepository<GameScore>.AddView<GameScoreView>(x => new GameScoreView { DateAdded = x.DateAdded, Score = x.Score }); } As you can see, using a little bit of lambda syntax, you put in the code for constructing a single view, this is used internally for mapping an entity to a view. *Note* you do not need to map the Id property, this is done automatically, a view model id will always be the same as it’s corresponding entity.   Adding Filters One of the cool features of the view is that you can add filters to limit the amount of data stored in the view, this will dramatically improve performance. You can add multiple filters using the fluent syntax if required. In this example, lets say that you will only ever show the scores for the last 10 days, you could add a filter like the following: Add single filter public MainPage() {     RapidRepository<GameScore>.AddView<GameScoreView>(x => new GameScoreView { DateAdded = x.DateAdded, Score = x.Score })         .AddFilter(x => x.DateAdded > DateTime.Now.AddDays(-10)); } If you wanted to further limit the data, you could also say only scores above 100: Add multiple filters public MainPage() {     RapidRepository<GameScore>.AddView<GameScoreView>(x => new GameScoreView { DateAdded = x.DateAdded, Score = x.Score })         .AddFilter(x => x.DateAdded > DateTime.Now.AddDays(-10))         .AddFilter(x => x.Score > 100); }   Querying the view model So the important part is how to query the data. This is done using the repository, there is a method called Query which accepts the type of view as a generic parameter (you can have multiple View Model types per entity type) You can either use the result of the query method directly or perform further querying on the result is required. Querying the View public void DisplayScores() {     RapidRepository<GameScore> repository = new RapidRepository<GameScore>();     List<GameScoreView> scores = repository.Query<GameScoreView>();       // display logic } Further Filtering public void TodaysScores() {     RapidRepository<GameScore> repository = new RapidRepository<GameScore>();     List<GameScoreView> todaysScores = repository.Query<GameScoreView>().Where(x => x.DateAdded > DateTime.Now.AddDays(-1)).ToList();       // display logic }   Retrieving the actual entity Retrieving the actual entity can be done easily by using the GetById method on the repository. Say for example you allow the user to click on a specific score to get further information, you can use the Id populated in the returned View Model GameScoreView and use it directly on the repository to retrieve the full entity. Get Full Entity public void GetFullEntity(Guid gameScoreViewId) {     RapidRepository<GameScore> repository = new RapidRepository<GameScore>();     GameScore fullEntity = repository.GetById(gameScoreViewId);       // display logic } Synchronising The View If you are upgrading from Rapid Repository V1.0 and are likely to have data in the repository already, you will need to perform a synchronisation to ensure the views and entities are fully in sync. You can either do this as a one off during the application upgrade or if you are a little more cautious, you could run this at each application start up. Synchronise the view public void MyUpgradeTasks() {     RapidRepository<GameScore>.SynchroniseView<GameScoreView>(); } It’s worth noting that in normal operation, the view keeps itself in sync with the entities so this is only really required if you are upgrading from V1.0 to V2.0 when it gets released shortly.   Summary I really hope you like this feature, it will be great for performance and I believe supports good practice by promoting the use of View Models for specific pages. I’m hoping to produce a beta for this over the next few days, I just want to add some more tests and hopefully iron out any bugs. I would really appreciate any thoughts on this feature and would really love to know of any bugs you find. You can download the source from the following : http://rapidrepository.codeplex.com/ Kind Regards, Sean McAlinden.

  • Rapid Repository – Silverlight Development

    - by SeanMcAlinden
    Hi All, One of the questions I was recently asked was whether the Rapid Repository would work for normal Silverlight development as well as for the Windows 7 Phone. I can confirm that the current code in the trunk will definitely work for both the Windows 7 Phone and normal Silverlight development. I haven’t tested V.1.0 for compatibility but V2.0 which will be released fairly soon will work absolutely fine.   Kind Regards, Sean McAlinden.

  • Windows Phone–A beautiful phone which I admire but I don’t recommend to friends and family

    - by Gopinath
    Microsoft’s Windows Phones are the most beautiful phones I’ve seen. Look at the photo which Microsoft shared on their Facebook page today. It’s gorgeous. Windows Phones come in vibrant colors and the user interface is very lively. When you keep an iPhone, Android Phone & a Windows Phone on a table, Windows Phone definitely stands out. Android and iOS interfaces are routine – a bunch of apps icons arranged in rows and multiple screens. Windows Phone is very different, the live tiles concept mesmerizes us. I love Windows Phone, but neither I buy one nor I recommend to family/friends! Why? Because it does not have all the Apps I need. Microsoft advertises that Windows Phone has 100K apps on its Windows Market Place. It’s true, there are 100K+ apps available for Windows Phone but not many of them are really useful and most of the popular Apps I use on Android are not available. When I say this to my friends at Microsoft, they don’t agree and one of them asked me list the apps that are not available. For him today I spent an hour quickly scanning through the apps installed on my Google Nexus and searched for same apps on Windows Market Place. As expected many of them are not available. Here is the list of my favorite Android apps that are not available for Windows Phone Mint – I use this app more than any of the Banking Apps I’ve installed on my mobile. It’s one app to keep a tab on all the expenses and income, the best money management and tracking app. Google Chrome – Web without Google Chrome is too boring, either on Desktop or on mobile. IE is too heavy and Firefox is loosing its grip. Chrome is the new darling of web. Pulse, Flipboard – Flipboard and Pulse are one of the best apps for reading news and following content of favorite blogs. Dropbox – Sync content across devices and provides access to your content on any device.It really does not matter what is your gadget – mobile, tablet or computer; Dropbox lets you access your content. GMail, Google Maps – Should I say how important are these two apps in our day to day life!! Vonage Extension – For around 30 bucks a month, Vonage provide landline service in USA + unlimited calls to India and many other countries + Vonage Extension App that lets Android/iOS mobile to make unlimited international calls for free. Without Vonage Extension app, I’m almost cutoff from my family and friends back home in India. Instagram – The most popular camera app used from a common man to celebrities. Raaga, Dhingana  – Music is part and parcel of life and these two apps are the most like popular apps to listen to Indian music. Quora – Quora is the place where most of the sensible discussions happen on web. Google Analytics, Google Adsense – I’m a blogger and these two apps mean a lot to me The list goes on and on! There are many useful apps that are not available on Windows Phone – TuneIn, MyTWC, Chrome To Phone, Google Voice, etc. Without all these apps, Windows Phone is just another old Nokia phone. Even though Windows Phone is the most beautiful phone, it needs Apps to attract customers. Without apps a smartphone is more or less a dumb feature phone which we loved to use before release of iPhone. Wish in an year or two the beautiful Windows Phone may have all the missing Apps. When it happens I’ll buy a phone for myself and recommend it to my family & friends. But till then I prefer to stay away.

  • Tips to Make Your Website Cell Phone Friendly

    - by Aditi
    Working on a new website design? or Redesigning your website? There is a lot more to consider now a days not just user experience, clean code, CSS etc. one of the important attribute one must not miss, which is making them mobile friendly! With the growing use of handhelds & unlimited data plans, people browse on their cellphones! and All come in different sizes! it is tough to make a website that would look great not just on a high resolution widescreen monitor/LCD, but also should look equally impressive on the low resolutions of cellphones. We are today going to discuss about such factors that can help you make a website Cellphone Friendly. Fluid Width Layouts As we start discussing about this, Most people speak of the Fluid Width Layouts as vital step in moving your website to be mobile friendly. Fluid width allows the width of your website stretch or shrink depending on the browser size. However, having a layout which flows with the width of the screen’s resolution is certainly convenient, more often than not the website was originally laid out for a desktop in mind. Compressing a fluid layout to 320 pixels can do some serious damage to layout, Thus some people strongly believe it is far better to have a mobile style sheet and lay out the content specifically for that screen and have more control on the display. The best thing to do is to detect the type of platform that is connected to your website and disabling or changing some tools and effects to make it look better if not perfect. Keep Your Web Pages Short length One must avoid long pages on their website, a lot of scroll makes it very non user friendly for people, especially on mobile devices this is a huge draw back because of the longer load time it takes to download the webpage. Everyone likes crisp & concise content such pages are easier to load & browse. This makes your website accessible across all platforms. Also try to keep shorter urls, if they have to type..save them from that much work especially if someone is using a cellphone with no QWERTY keyboard it can be tough. Usable Navigation & Search Unlike Desktops, your website’s Navigation won’t super work on a cellphone. Keep in mind the user experience for cellphone users as you design your Navigation. Try to keep your content centered as they do have difficulty in reading the webpage. I always look upto Google and their pages as available on mobile as a great example. Keeping a functional & very visible search bar helps mobile users navigate by searching. Understanding Clean Website Code : Evolved for Mobile Clean code is important when you consider the diversity out there for handheld devices. Some cell phones may only understand WAP. More capable phones may understand WAP2, which allows rendering websites with XHTML and CSS. Most mobiles won’t display tables, floats, frames, JavaScript, and dynamic menus. Most cellphone will not support cookies. Devices at the high end of the mobile market such as BlackBerry, Palm, or the upcoming iPhone are highly capable and support nearly as much as a standard computer..but masses still do not have such phones. You can use specific emulators to test your website on mobile devices. Make sure your color combinations provide good contrast between foreground and background colors, particularly for devices with fewer color options.

  • Windows Phone 7 development: first impressions

    - by DigiMortal
    After hard week in work I got some free time to play with Windows Phone 7 CTP developer tools. Although my first test application is still unfinished I think it is good moment to share my first experiences to you. In this posting I will give you quick overview of Windows Phone 7 developer tools from developer perspective. If you are familiar with Visual Studio 2010 then you will feel comfortable because Windows Phone 7 CTP developer tools base on Visual Studio 2010 Express. Project templates There are five project templates available. Three of them are based on Silverlight and two on XNA Game Studio: Windows Phone Application (Silverlight) Windows Phone List Application (Silverlight) Windows Phone Class Library (Silverlight) Windows Phone Game (XNA Game Studio) Windows Phone Game Library (XNA Game Studio) Currently I am writing to test applications. One of them is based on Windows Phone Application and the other on Windows Phone List Application project template. After creating these projects you see the following views in Visual Studio. Windows Phone Application. Click on image to enlarge. Windows Phone List Application. Click on image to enlarge.  I suggest you to use some of these templates to get started more easily. Windows Phone 7 emulator You can run your Windows Phone 7 applications on Windows Phone 7 emulator that comes with developer tools CTP. If you run your application then emulator is started automatically and you can try out how your application works in phone-like emulator. You can see screenshot of emulator on right. Currently there is opened Windows Phone List Application as it is created by default. Click on image to enlarge it. Emulator is a little bit slow and uncomfortable but it works pretty well. This far I have caused only couple of crashes during my experiments. In these cases emulator works but Visual Studio gets stuck because it cannot communicate with emulator. One important note. Emulator is based on virtual machine although you can see only phone screen and options toolbar. If you want to run emulator you must close all virtual machines running on your machine and run Visual Studio 2010 as administrator. Once you run emulator you can keep it open because you can stop your application in Visual Studio, modify, compile and re-deploy it without restarting emulator. Designing user interfaces You can design user interface of your application in Visual Studio. When you open XAML-files it is displayed in window with two panels. Left panel shows you device screen and works as visual design environment while right panel shows you XAML mark-up and let’s you modify XML if you need it. As it is one of my very first Silverlight applications I felt more comfortable with XAML editor because property names in property boxes of visual designer confused me a little bit. Designer panel is not very good because it is visually hard to follow. It has black background that makes dark borders of controls very hard to see. If you have monitor with very high contrast then it is may be not a real problem. I have usual monitor and I have problem. :) Putting controls on design surface, dragging and resizing them is also pretty painful. Some controls are drawn correctly but for some controls you have to set width and height in XML so they can be resized. After some practicing it is not so annoying anymore. On the right you can see toolbox with some controllers. This is all you get out of the box. But it is sufficient to get started. After getting some experiences you can create your own controls or use existing ones from other vendors or developers. If it is your first time to do stuff with Silverlight then keep Google open – you need it hard. After getting over the first shock you get the point very quickly and start developing at normal speed. :) Writing source code Writing source code is the most familiar part of this action. Good old Visual Studio code editor with all nice features it has. But here you get also some surprises: The anatomy of Silverlight controls is a little bit different than the one of user controls in web and forms projects. Windows Phone 7 doesn’t run on full version of Windows (I bet it is some version of Windows CE or something like this) then there is less system classes you can use. Some familiar classes have less methods that in full version of .NET Framework and in these cases you have to write all the code by yourself or find libraries or source code from somewhere. These problems are really not so much problems than limitations and you get easily over them. Conclusion Windows Phone 7 CTP developer tools help you do a lot of things on Windows Phone 7. Although I expected better performance from tools I think that current performance is not a problem. This far my first test project is going very well and Google has answer for almost every question. Windows Phone 7 is mobile device and therefore it has less hardware resources than desktop computers. This is why toolset is so limited. The more you need memory the more slower is device and as you may guess it needs the more battery. If you are writing apps for mobile devices then make your best to get your application use as few resources as possible and act as fast as possible.

  • windows phone application repeatedly opens while phone is plugged in

    - by Nathan DeWitt
    I plugged my windows phone 8 phone into my Windows 8.1 computer for the first time. It asked what to do when a WP8 phone is plugged in. I chose "Open Windows Phone". All worked fine for about an hour. Now when I connect my phone, the Windows Phone application repeatedly opens. I can't even type in another window, as it continues to steal focus to "switch to" the Windows Phone application. Anyone have any ideas to fix this?

  • Building a Windows Phone 7 Twitter Application using Silverlight

    - by ScottGu
    On Monday I had the opportunity to present the MIX 2010 Day 1 Keynote in Las Vegas (you can watch a video of it here).  In the keynote I announced the release of the Silverlight 4 Release Candidate (we’ll ship the final release of it next month) and the VS 2010 RC tools for Silverlight 4.  I also had the chance to talk for the first time about how Silverlight and XNA can now be used to build Windows Phone 7 applications. During my talk I did two quick Windows Phone 7 coding demos using Silverlight – a quick “Hello World” application and a “Twitter” data-snacking application.  Both applications were easy to build and only took a few minutes to create on stage.  Below are the steps you can follow yourself to build them on your own machines as well. [Note: In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu] Building a “Hello World” Windows Phone 7 Application First make sure you’ve installed the Windows Phone Developer Tools CTP – this includes the Visual Studio 2010 Express for Windows Phone development tool (which will be free forever and is the only thing you need to develop and build Windows Phone 7 applications) as well as an add-on to the VS 2010 RC that enables phone development within the full VS 2010 as well. After you’ve downloaded and installed the Windows Phone Developer Tools CTP, launch the Visual Studio 2010 Express for Windows Phone that it installs or launch the VS 2010 RC (if you have it already installed), and then choose “File”->”New Project.”  Here, you’ll find the usual list of project template types along with a new category: “Silverlight for Windows Phone”. The first CTP offers two application project templates. The first is the “Windows Phone Application” template - this is what we’ll use for this example. The second is the “Windows Phone List Application” template - which provides the basic layout for a master-details phone application: After creating a new project, you’ll get a view of the design surface and markup. Notice that the design surface shows the phone UI, letting you easily see how your application will look while you develop. For those familiar with Visual Studio, you’ll also find the familiar ToolBox, Solution Explorer and Properties pane. For our HelloWorld application, we’ll start out by adding a TextBox and a Button from the Toolbox. Notice that you get the same design experience as you do for Silverlight on the web or desktop. You can easily resize, position and align your controls on the design surface. Changing properties is easy with the Properties pane. We’ll change the name of the TextBox that we added to username and change the page title text to “Hello world.” We’ll then write some code by double-clicking on the button and create an event handler in the code-behind file (MainPage.xaml.cs). We’ll start out by changing the title text of the application. The project template included this title as a TextBlock with the name textBlockListTitle (note that the current name incorrectly includes the word “list”; that will be fixed for the final release.)  As we write code against it we get intellisense showing the members available.  Below we’ll set the Text property of the title TextBlock to “Hello “ + the Text property of the TextBox username: We now have all the code necessary for a Hello World application.  We have two choices when it comes to deploying and running the application. We can either deploy to an actual device itself or use the built-in phone emulator: Because the phone emulator is actually the phone operating system running in a virtual machine, we’ll get the same experience developing in the emulator as on the device. For this sample, we’ll just press F5 to start the application with debugging using the emulator.  Once the phone operating system loads, the emulator will run the new “Hello world” application exactly as it would on the device: Notice that we can change several settings of the emulator experience with the emulator toolbar – which is a floating toolbar on the top right.  This includes the ability to re-size/zoom the emulator and two rotate buttons.  Zoom lets us zoom into even the smallest detail of the application: The orientation buttons allow us easily see what the application looks like in landscape mode (orientation change support is just built into the default template): Note that the emulator can be reused across F5 debug sessions - that means that we don’t have to start the emulator for every deployment. We’ve added a dialog that will help you from accidentally shutting down the emulator if you want to reuse it.  Launching an application on an already running emulator should only take ~3 seconds to deploy and run. Within our Hello World application we’ll click the “username” textbox to give it focus.  This will cause the software input panel (SIP) to open up automatically.  We can either type a message or – since we are using the emulator – just type in text.  Note that the emulator works with Windows 7 multi-touch so, if you have a touchscreen, you can see how interaction will feel on a device just by pressing the screen. We’ll enter “MIX 10” in the textbox and then click the button – this will cause the title to update to be “Hello MIX 10”: We provide the same Visual Studio experience when developing for the phone as other .NET applications. This means that we can set a breakpoint within the button event handler, press the button again and have it break within the debugger: Building a “Twitter” Windows Phone 7 Application using Silverlight Rather than just stop with “Hello World” let’s keep going and evolve it to be a basic Twitter client application. We’ll return to the design surface and add a ListBox, using the snaplines within the designer to fit it to the device screen and make the best use of phone screen real estate.  We’ll also rename the Button “Lookup”: We’ll then return to the Button event handler in Main.xaml.cs, and remove the original “Hello World” line of code and take advantage of the WebClient networking class to asynchronously download a Twitter feed. This takes three lines of code in total: (1) declaring and creating the WebClient, (2) attaching an event handler and then (3) calling the asynchronous DownloadStringAsync method. In the DownloadStringAsync call, we’ll pass a Twitter Uri plus a query string which pulls the text from the “username” TextBox. This feed will pull down the respective user’s most frequent posts in an XML format. When the call completes, the DownloadStringCompleted event is fired and our generated event handler twitter_DownloadStringCompleted will be called: The result returned from the Twitter call will come back in an XML based format.  To parse this we’ll use LINQ to XML. LINQ to XML lets us create simple queries for accessing data in an xml feed. To use this library, we’ll first need to add a reference to the assembly (right click on the References folder in the solution explorer and choose “Add Reference): We’ll then add a “using System.Xml.Linq” namespace reference at the top of the code-behind file at the top of Main.xaml.cs file: We’ll then add a simple helper class called TwitterItem to our project. TwitterItem has three string members – UserName, Message and ImageSource: We’ll then implement the twitter_DownloadStringCompleted event handler and use LINQ to XML to parse the returned XML string from Twitter.  What the query is doing is pulling out the three key pieces of information for each Twitter post from the username we passed as the query string. These are the ImageSource for their profile image, the Message of their tweet and their UserName. For each Tweet in the XML, we are creating a new TwitterItem in the IEnumerable<XElement> returned by the Linq query.  We then assign the generated TwitterItem sequence to the ListBox’s ItemsSource property: We’ll then do one more step to complete the application. In the Main.xaml file, we’ll add an ItemTemplate to the ListBox. For the demo, I used a simple template that uses databinding to show the user’s profile image, their tweet and their username. <ListBox Height="521" HorizonalAlignment="Left" Margin="0,131,0,0" Name="listBox1" VerticalAlignment="Top" Width="476"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal" Height="132"> <Image Source="{Binding ImageSource}" Height="73" Width="73" VerticalAlignment="Top" Margin="0,10,8,0"/> <StackPanel Width="370"> <TextBlock Text="{Binding UserName}" Foreground="#FFC8AB14" FontSize="28" /> <TextBlock Text="{Binding Message}" TextWrapping="Wrap" FontSize="24" /> </StackPanel> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> Now, pressing F5 again, we are able to reuse the emulator and re-run the application. Once the application has launched, we can type in a Twitter username and press the  Button to see the results. Try my Twitter user name (scottgu) and you’ll get back a result of TwitterItems in the Listbox: Try using the mouse (or if you have a touchscreen device your finger) to scroll the items in the Listbox – you should find that they move very fast within the emulator.  This is because the emulator is hardware accelerated – and so gives you the same fast performance that you get on the actual phone hardware. Summary Silverlight and the VS 2010 Tools for Windows Phone (and the corresponding Expression Blend Tools for Windows Phone) make building Windows Phone applications both really easy and fun.  At MIX this week a number of great partners (including Netflix, FourSquare, Seesmic, Shazaam, Major League Soccer, Graphic.ly, Associated Press, Jackson Fish and more) showed off some killer application prototypes they’ve built over the last few weeks.  You can watch my full day 1 keynote to see them in action. I think they start to show some of the promise and potential of using Silverlight with Windows Phone 7.  I’ll be doing more blog posts in the weeks and months ahead that cover that more. Hope this helps, Scott

  • UITabbleView Sections /cellForRowAtIndexPath method

    hello, i have a sectioned tableview in a detailviewcontroller where i load some data in the first section. this is my code: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue2 reuseIdentifier:CellIdentifier] autorelease]; } // For the Ingredients section, if necessary create a new cell and configure it with an additional label for the amount. Give the cell a different identifier from that used for cells in other sections so that it can be dequeued separately. if (indexPath.section == PARAMETERS_SECTION) { switch(indexPath.row) { case 0: cell.textLabel.text = @"Pili"; cell.textLabel.numberOfLines = 1; cell.textLabel.textAlignment = UITextAlignmentLeft; cell.detailTextLabel.text = entity.stid; cell.detailTextLabel.font = [UIFont boldSystemFontOfSize:12]; cell.detailTextLabel.numberOfLines = 2; break; case 1: cell.textLabel.text = @"Pele"; cell.textLabel.numberOfLines = 1; cell.textLabel.textAlignment = UITextAlignmentLeft; cell.detailTextLabel.text = entity.arec; cell.detailTextLabel.font = [UIFont boldSystemFontOfSize:11]; cell.detailTextLabel.numberOfLines = 5; break; case 2: cell.textLabel.text = @"Pale"; cell.textLabel.numberOfLines = 1; cell.textLabel.textAlignment = UITextAlignmentLeft; cell.detailTextLabel.text = entity.wer; cell.detailTextLabel.font = [UIFont boldSystemFontOfSize:11]; cell.detailTextLabel.numberOfLines = 3; break; case 3: cell.textLabel.text = @"Pole"; cell.textLabel.numberOfLines = 1; cell.textLabel.textAlignment = UITextAlignmentLeft; cell.detailTextLabel.text = entity.groid; cell.detailTextLabel.font = [UIFont boldSystemFontOfSize:11]; cell.detailTextLabel.numberOfLines = 3; break; default: break; } if (indexPath.section == NOTES_SECTION) { NSString *text = nil; text = @"User Notes"; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; cell.editingAccessoryType = UITableViewCellAccessoryNone; cell.selectionStyle = UITableViewCellSelectionStyleBlue; cell.textLabel.text = text; } if (indexPath.section == EVALUATION_SECTION) { NSString *text = nil; text = @"Evaluation"; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; cell.editingAccessoryType = UITableViewCellAccessoryNone; cell.selectionStyle = UITableViewCellSelectionStyleBlue; cell.textLabel.text = text; } if (indexPath.section == CENTERING_SECTION) { NSString *text = nil; text = @"Centering"; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; cell.editingAccessoryType = UITableViewCellAccessoryNone; cell.selectionStyle = UITableViewCellSelectionStyleBlue; cell.textLabel.text = text; } } return cell; } everything works ok for the first section. the rest of them seem to be "ignored" Can someone help me? thank you!

  • Test All Features of Windows Phone 7 On Your PC

    - by Matthew Guay
    Are you developer or just excited about the upcoming Windows Phone 7, and want to try it out now?  Thanks to free developer tools from Microsoft and a new unlocked emulator rom, you can try out most of the exciting features today from your PC. Last week we showed you how to try out Windows Phone 7 on your PC and get started developing for the upcoming new devices.  We noticed, however, that the emulator only contains Internet Explorer Mobile and some settings.  This is still interesting to play around with, but it wasn’t the full Windows Phone 7 experience. Some enterprising tweakers discovered that more applications were actually included in the emulator, but were simply hidden from users.  Developer Dan Ardelean then figured out how to re-enable these features, and released a tweaked emulator rom so everyone can try out all of the Windows Phone 7 features for themselves.  Here we’ll look at how you can run this new emulator image on your PC, and then look at some interesting features in Windows Phone 7. Editor Note: This modified emulator image is not official, and isn’t sanctioned by Microsoft. Use your own judgment when choosing to download and use the emulator. Setting Up Emulator Rom To test-drive Windows Phone 7 on your PC, you must first download and install the Windows Phone Developer Tools CTP (link below).  Follow the steps we showed you last week at: Try out Windows Phone 7 on your PC today.  Once it’s installed, go ahead and run the default emulator as we showed to make sure everything works ok. Once the Windows Phone Developer Tools are installed and running, download the new emulator rom from XDA Forums (link below).  This will be a zip file, so extract it first. Note where you save the file, as you will need the address in the next step. Now, to run our new emulator image, we need to open the emulator in command line and point to the new rom image.  To do this, browse to the correct directory, depending on whether you’re running the 32 bit or 64 bit version of Windows: 32 bit: C:\Program Files\Microsoft XDE\1.0\ 64 bit: C:\Program Files (x86)\Microsoft XDE\1.0\ Hold your Shift key down and right-click in the folder.  Choose Open Command Window here. At the command prompt, enter XDE.exe followed by the location of your new rom image.  Here, we downloaded the rom to our download folder, so at the command prompt we entered: XDE.exe C:\Users\Matthew\Downloads\WM70Full\WM70Full.bin The emulator loads … with the full Windows Phone 7 experience! To make it easier, let’s make a shortcut on our desktop to load the emulator with the new rom directly.  Right-click on your desktop (or any folder you want to create the shortcut in), select New, and then Shortcut. Now, in the box, we need to enter the path for the emulator followed by the location of our rom.  Both items must be in quotes.  So, in our test, we entered the following: 32 bit: “C:\Program Files\Microsoft XDE\1.0\” “C:\Users\Matthew\Downloads\WM70Full\WM70Full.bin” 64 bit: “C:\Program Files (x86)\Microsoft XDE\1.0\” “C:\Users\Matthew\Downloads\WM70Full\WM70Full.bin” Make sure to enter the correct location of the new emulator rom for your computer, and keep both items in separate quotes.  Click next when you’ve entered the location. Name the shortcut; we named it Windows Phone 7, but simply enter whatever you’d like.  Click Finish when you’re done. You should now have a nice Windows Phone icon and your fully functional shortcut!  Double-click it to run the Windows Phone 7 emulator as above. Features in the Unlocked Windows Phone 7 Emulator So let’s look at what you can do with this new emulator.  Almost everything you’ve seen in demos from the Mobile World Conference and Mix’10 are right here for you to play with.  Here’s the application menu, which you can access by clicking on the arrow on the top of the home screen, which shows how much stuff they’ve got in this!   And, of course, even the home screen itself shows much more activity than it did in the original emulator. Let’s check out some of these sections.  Here’s Zune running on Windows Phone 7, and the Zune Marketplace.  The animations are beautiful, so be sure to check this out yourself. The new picture hub is much nicer than any picture viewer included with Windows Mobile in the past…   Stay productive, and on schedule with the new Calendar. The XBOX hub gives us only a hint of things to come, and the links to games now are simply placeholders. Here’s a look at the Office hub.  This doesn’t show up on the homescreen right now, but you can access it in the applications menu.  Office obviously still has a lot of work left on it, but even at a glance here it looks like it includes a lot more functionality than Office Mobile in Windows Mobile 6. Here’s a look at each of the three apps: Word, Excel, and OneNote, and the formatting pallet in Office apps.   This emulator also includes a lot more settings than the default one, including settings for individual applications. You can even activate the screen lock, and try out the lift-to-peek-or-unlock feature… Finally, this version of Windows Phone 7 includes a very nice SystemInfo app with an advanced task manager.  We hope this is still available when the actual phones are released. Conclusion If you’re excited about the upcoming Windows Phone 7 series, or simply want to learn more about what’s coming, this is a great way to test it out.  With these exciting new hubs and applications, there’s something here for everyone.  Let us know what you like most about Windows Phone 7 and what your favorite app or hub is.

    Suppose that we have this cell array of data : a={43 432 2006; 254 12 2008; 65 35 2000; 64 34 2000; 23 23 2006; 64 2 2010; 32 5 2006; 22 2 2010} Last column of this cell array is years. I want classify data(rows) based on years like this : a_2006 = {43 432 2006; 32 5 2006; 32 5 2006} a_2008 = {254 12 2008}; a_2000 = {65 35 2000; 64 34 2000} a_2010 = {64 2 2010; 22 2 2010} I have different years in column three in every cell array (this cell array is a sample) so I want an automatic method to determine the years and classify them to a_yearA , a_yearB etc. or other naming that I can distinguish years and call data years easily. How can I do this? Thanks.da

  • Make Your PC Look Like Windows Phone 7

    - by Matthew Guay
    Windows Phone 7 offers a unique and exciting UI that displays lots of information efficiently on the screen.  And with a simple Rainmeter theme, you can have the same UI and content directly on your Windows 7 desktop. Turn your Desktop into a Windows Phone 7 lookalike To give your Windows 7 desktop a Windows Phone 7 makeover, first you need to have the free Rainmeter application installed.  If you do not have it installed, download it from the link below and run the setup.  Accept the license agreement, and install it with the default settings. By default Rainmeter will automatically run when you start your computer.  If you do not want this, you can uncheck the box during the setup. Now, download the Omnimo UI theme for Rainmeter (link below).  You will need to unzip the folder first. This theme uses the Segoe UI and the Segoe UI Light font, so Windows Vista users need to install the segoeuil.ttf font first, and XP users need to install both the segoeui.ttf and the segoeuil.ttf font first.  Copy the appropriate fonts to C:\Windows\Fonts, or in Vista double-click on the font and select Install. Now, run the Rainmeter theme setup.  Double-click on the Rainstaller.exe in the Omnimo folder. Click Express install to add the theme and skin to Rainmeter. Click Finish, and by default Rainmeter will open with your new theme. When the new theme opens the first time, you will be asked to read the readme, or simply go to the gallery. When you open the gallery, you can choose from a wide variety of tiles and gadgets to place on your desktop.  You can also choose a different color scheme for your tiles. Once you’re done, click the X in the top right hand corner to close the Gallery.  Welcome to your Windows Phone 7 desktop!  Many of the gadgets are dynamic, and you can change the settings for most of them.  The only thing missing is the transition animations that Windows Phone 7 shows when you launch an application. To make it look even more like Windows Phone 7, you can change your background to black.  This makes the desktop theme really dramatic. And, if you want to add gadgets or change the color scheme, simply click on the + logo on the top. Windows Phone 7 Desktop Wallpapers If you’d prefer to simply change your background, My Microsoft Life has several very nice Windows Phone 7 wallpapers available for free.  Click the link below to download these and other Microsoft-centric wallpapers. If you can’t wait to get the new Windows phone 7, this is a great way to start experiencing the beauty of the phone UI on your desktop.

  • How to make phone calls using a phone

    - by user18151
    Hi, I have a phone landline connection and I DO NOT have a phone instrument. I connect the cable into my laptop, and want to make calls using my laptop. I have an HDA CX20561 modem. I seem to be able to dial number using dialer.exe, though nothing seems to happen. From Microsoft kb http://support.microsoft.com/kb/958143, it looks like dialer.exe alone is not enough for the call. Can somebody tell me how to make and receive phone call with whatever hardware I have, i.e. what software will I need. Thanks.

  • Windows Phone 8 not interfacing with Zune software

    - by Cyberherbalist
    I just got a Lumia 521 with Windows Phone 8 and am trying to get the device to work with the Zune software on my PC. I still have my Windows Phone 7 device, and the new one is not working the same way. When I plug the WP7 device into the PC's USB port, it automatically fires up Zune and I can sync my podcasts and music etc to the device. But when I plug the Lumia into the PC it doesn't fire up Zune, and if I start Zune manually, it doesn't interface with the phone at all. Perhaps I am missing something and WP8 isn't supposed to use Zune to interface with the phone?
