  • Castle Active Record - Working with the cache

    - by David
    Hi All, im new to the Castle Active Record Pattern and Im trying to get my head around how to effectivley use cache. So what im trying to do (or want to do) is when calling the GetAll, find out if I have called it before and check the cache, else load it, but I also want to pass a bool paramter that will force the cache to clear and requery the db. So Im just looking for the final bits. thanks public static List<Model.Resource> GetAll(bool forceReload) { List<Model.Resource> resources = new List<Model.Resource>(); //Request to force reload if (forceReload) { //need to specify to force a reload (how?) XmlConfigurationSource source = new XmlConfigurationSource("appconfig.xml"); ActiveRecordStarter.Initialize(source, typeof(Model.Resource)); resources = Model.Resource.FindAll().ToList(); } else { //Check the cache somehow and return the cache? } return resources; } public static List<Model.Resource> GetAll() { return GetAll(false); }

  • slow SQL command

    - by Retrocoder
    I need to take some data from one table (and expand some XML on the way) and put it in another table. As the source table can have thousands or records which caused a timeout I decided to do it in batches of 100 records. The code is run on a schedule so doing it in batches works ok for the customer. If I have say 200 records in the source database the sproc runs very fast but if there are thousands it takes several minutes. I'm guessing that the "TOP 100" only takes the top 100 after it has gone through all the records. I need to change the whole code and sproc at some point as it doesn't scale but for now is there a quick fix to make this run quicker ? INSERT INTO [deviceManager].[TransactionLogStores] SELECT TOP 100 [EventId], [message].value('(/interface/mac)[1]', 'nvarchar(100)') AS mac, [message].value('(/interface/device) [1]', 'nvarchar(100)') AS device_type, [message].value('(/interface/id) [1]', 'nvarchar(100)') AS device_id, [message].value('substring(string((/interface/id)[1]), 1, 6)', 'nvarchar(100)') AS store_id, [message].value('(/interface/terminal/unit)[1]', 'nvarchar(100)') AS unit, [message].value('(/interface/terminal/trans/event)[1]', 'nvarchar(100)') AS event_id, [message].value('(/interface/terminal/trans/data)[1]', 'nvarchar(100)') AS event_data, [message].value('substring(string((/interface/terminal/trans/data)[1]), 9, 11)', 'nvarchar(100)') AS badge, [message].value('(/interface/terminal/trans/time)[1]', 'nvarchar(100)') AS terminal_time, MessageRecievedAt_UTC AS db_time FROM [deviceManager].[TransactionLog] WHERE EventId > @EventId --WHERE MessageRecievedAt_UTC > @StartTime AND MessageRecievedAt_UTC < @EndTime ORDER BY terminal_time DESC

  • MPAPI vs MPI.NET vs ?

    - by Olexandr
    I'm working on college project. I have to develop distributed computing system. And i decided to do some research to make this task fun :) I've found MPAPI and MPI.NET libraries. Yes, they are .NET libraries(Mono, in my case). Why .NET ? I'm choosing between Ada, C++ and C# so to i've choosed C# because of lower development time. I have two goals: Simplicity; Performance; Cluster computing. So, what to choose - MPAPI or MPI.NET or something else ?

  • Django internationalization for admin pages - translate model name and attributes

    - by geekQ
    Django's internationalization is very nice (gettext based, LocaleMiddleware), but what is the proper way to translate the model name and the attributes for admin pages? I did not find anything about this in the documentation: http://docs.djangoproject.com/en/dev/topics/i18n/internationalization/ http://www.djangobook.com/en/2.0/chapter19/ I would like to have "???????? ????? ??? ?????????" instead of "???????? order ??? ?????????". Note, the 'order' is not translated. First, I defined a model, activated USE_I18N = True in settings.py, run django-admin makemessages -l ru. No entries are created by default for model names and attributes. Grepping in the Django source code I found: $ ack "Select %s to change" contrib/admin/views/main.py 70: self.title = (self.is_popup and ugettext('Select %s') % force_unicode(self.opts.verbose_name) or ugettext('Select %s to change') % force_unicode(self.opts.verbose_name)) So the verbose_name meta property seems to play some role here. Tried to use it: class Order(models.Model): subject = models.CharField(max_length=150) description = models.TextField() class Meta: verbose_name = _('order') Now the updated po file contains msgid 'order' that can be translated. So I put the translation in. Unfortunately running the admin pages show the same mix of "???????? order ??? ?????????". I'm currently using Django 1.1.1. Could somebody point me to the relevant documentation? Because google can not. ;-) In the mean time I'll dig deeper into the django source code...

  • Help getting MVVM ViewModel to bind to the View

    - by cw
    Okay guys, I'm new to this model and Silverlight in general. I have the following code (changed object names, so syntax/spelling errors ignore). public class ViewModel { ViewModelSource m_vSource; public ViewModel(IViewModelSource source) { m_vSource= source; m_vSource.ItemArrived += new Action<Item>(m_vSource_ItemArrived); } void m_vSource_ItemArrived(Item obj) { Title = obj.Title; Subitems = obj.items; Description = obj.Description; } public void GetFeed(string serviceUrl) { m_vFeedSource.GetFeed(serviceUrl); } public string Title { get; set; } public IEnumerable<Subitems> Subitems { get; set; } public string Description { get; set; } } Here is the code I have in my page's codebehind. ViewModel m_vViewModel; public MainPage() { InitializeComponent(); m_vViewModel = new ViewModel(new ViewModelSource()); this.Loaded += new RoutedEventHandler(MainPage_Loaded); this.DataContext = m_vViewModel; } void MainPage_Loaded(object sender, RoutedEventArgs e) { m_vViewModel.GetItems("http://www.myserviceurl.com"); } Finally, here is a sample of what my xaml looks like. <!--TitleGrid is the name of the application and page title--> <Grid x:Name="TitleGrid" Grid.Row="0"> <TextBlock Text="My Super Title" x:Name="textBlockPageTitle" Style="{StaticResource PhoneTextPageTitle1Style}"/> <TextBlock Text="{Binding Path=Title}" x:Name="textBlockListTitle" Style="{StaticResource PhoneTextPageTitle2Style}"/> </Grid> I know I'm missing something, but I'm just not knowledgable enough which is why I'm asking you guys :) Is there anything I'm doing wrong here? Thanks!

  • ASP.NET membership db using integrated security problem

    - by rem
    I published ASP.NET MVC web site to a server on a virtual machine (Hyper-V). SQL Server Express installed on the same server. The problem is that ASP.Net Membership system doesn't work in integrated mode. When Web.config file contains records as follows: <connectionStrings> <remove name="LocalSqlServer" /> <add name="MyDBConnectionString" connectionString="data source=vm-1\SQLEXPRESS;Initial Catalog=testdb;Integrated Security=SSPI;" providerName="System.Data.SqlClient"/> </connectionStrings> I get an error when trying to register and login to the site. If I change connection string this way: <connectionStrings> <remove name="LocalSqlServer" /> <add name="MyDBConnectionString" connectionString="data source=vm-1\SQLEXPRESS;Initial Catalog=testdb;User ID=XX;Password=XXXXXXX;" providerName="System.Data.SqlClient"/> </connectionStrings> I could register and login without any problem. What could cause the problem with using ASP.NET membership database in integrated security mode?

  • How can I place zeroes to the left of a given number to a maximum of 6 digits including the given nu

    - by Sergio Tapia
    I have this method that receives an ID number and downloads an HTML website according to that ID. Typically, an IMDB link is like this: http://www.imdb.com/title/tt0892791/ http://www.imdb.com/title/tt1226229/ http://www.imdb.com/title/tt0000429/ They all follow the 'tt' then 7 digits, with lack of digits turning into zeroes to fill out the left spaces. How can I accomplish this using C#? I'm kind of stumped. Here's my method: /// <summary> /// Find a movie page using its precise IMDB id. /// </summary> /// <param name="id">IMDB Movie ID</param> /// <returns>Returns an HtmlDocument with the source code included.</returns> public HtmlDocument ByID(string id) { string url = String.Format("http://www.imdb.com/title/tt{0}/", id); HtmlDocument page = downloader.Load(url); return page; } Thank you very much for your time, and if you are interested in helping out, you can check out the complete source code of TheFreeIMDB here: http://thefreeimdb.codeplex.com/

  • Streaming Media Player Tutorial Stops Unexpectedly. How Should I Debug (And Other Questions From A

    - by Danny
    Hello! I'm a fledgling in the Android and Eclipse ways. I was reading and downloaded the source code for a Streaming Media Player tutorial from Pocket Journey, here. However, when I try to run it through the "Run As..." or "Debug As..." features in Eclipse, the emulator reports: "Sorry! The application Android Tutorials (process com.pocketjourney.tutorials) has stopped unexpectedly. Please try again." Now, from stepping through the Tutorial 1 activity (for those of you that may be familiar with it), it seems something funky happens here: button.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { Toast.makeText(Tutorial1.this, "Button Clicked",Toast.LENGTH_SHORT).show(); }}); My questions are: What's up with that line? Apparently, other comments haven't had this problem; am I missing some library that I should be downloading from someplace? How should I go about debugging this other than/in addition to stepping through code? I'm used to Visual Studio, which has a nice box with exception details for me to sift through and copy/paste to google with. Eclipse debugging showed a "No Source Code" page, or a list of exceptions. I've heard of something called LogCat; is that relevant here? Thanks in advance!

  • Copy SQL Server data from one server to another on a schedule

    - by rwmnau
    I have a pair of SQL Servers at different webhosts, and I'm looking for a way to periodically update the one server using the other. Here's what I'm looking for: As automated as possible - ideally, without any involvement on my part once it's set up. Pushes a number of databases, in their entirely (including any schema changes) from one server to the other Freely allows changes on the source server without breaking my process. For this reason, I don't want to use replication, as I'd have to break it every time there's an update on the source, and then recreate the publication and subscription One database is about 4GB in size and contains binary data. I'm not sure if there's a way to export this to a script, but it would be a mammoth file if I did. Originally, I was thinking of writing something that takes a scheduled full backup of each database, FTPs the backups from one server to the other once they're done, and then the new server picks it up and restores it. The only downside I can see to this is that there's no way to know that the backups are done before starting to transfer them - can these backups be done synchronously? Also, the server being refreshes is our test server, so if there's some downtime involved in moving the data, that's fine. Does anybody out there have a better idea, or is what I'm currently considering the best non-replication way to go? Thanks for your help, everybody. UPDATE: I ended up designing a custom solution to get this done using BAT files, 7Zip,command line FTP, and OSQL, so it runs in a completely automatic way and aggregates the data from a dozen servers across the country. I've detailed the steps in a blog entry. Thanks for all your input!

  • Distributing WPF apps to a legacy user base: How seamless is it?

    - by Christian Nunciato
    I'm considering developing a WPF application, to be hosted by a legacy Windows app (C++), and I'm trying to get a better sense of how feasible it'll be to do so, given the broad user base I'm targeting. Knowing WPF targets .NET 3.5, I'm looking for some insight as to what the field looks like right now -- who's already got the runtime, whether it's distributed by Windows Update, if so, how (e.g., as an optional or required download, to which operating systems, etc.), whether XP pre-XP2 supports it (and how), and so on. The current version's got many thousands of users, using all manner of Windows operating systems, and while I'd very much like to leverage WPF to breathe some life into their user experience, I want to make sure I'm not shutting anyone out by doing so, or burdening them with a download they might have to do manually. I realize most, or all, of this information's out there already, in various places, but I figured I'd ask here first, since I'm sure some of you've probably already gone down this road and have valuable experiences to share. Thanks in advance!

  • Retrieving dll version info via Win32 - VerQueryValue(...) crashes under Win7 x64

    - by user256890
    The respected open source .NET wrapper implementation (SharpBITS) of Windows BITS services fails identifying the underlying BITS version under Win7 x64. Here is the source code that fails. NativeMethods are native Win32 calls wrapped by .NET methods and decorated via DllImport attribute. private static BitsVersion GetBitsVersion() { try { string fileName = Path.Combine( System.Environment.SystemDirectory, "qmgr.dll"); int handle = 0; int size = NativeMethods.GetFileVersionInfoSize(fileName, out handle); if (size == 0) return BitsVersion.Bits0_0; byte[] buffer = new byte[size]; if (!NativeMethods.GetFileVersionInfo(fileName, handle, size, buffer)) { return BitsVersion.Bits0_0; } IntPtr subBlock = IntPtr.Zero; uint len = 0; if (!NativeMethods.VerQueryValue(buffer, @"\VarFileInfo\Translation", out subBlock, out len)) { return BitsVersion.Bits0_0; } int block1 = Marshal.ReadInt16(subBlock); int block2 = Marshal.ReadInt16((IntPtr)((int)subBlock + 2 )); string spv = string.Format( @"\StringFileInfo\{0:X4}{1:X4}\ProductVersion", block1, block2); string versionInfo; if (!NativeMethods.VerQueryValue(buffer, spv, out versionInfo, out len)) { return BitsVersion.Bits0_0; } ... The implementation follows the MSDN instructions by the letter. Still during the second VerQueryValue(...) call, the application crashes and kills the debug session without hesitation. Just a little more debug info right before the crash: spv = "\StringFileInfo\040904B0\ProductVersion" buffer = byte[1900] - full with binary data block1 = 1033 block2 = 1200 I looked at the targeted "C:\Windows\System32\qmgr.dll" file (The implementation of BITS) via Windows. It says that the Product Version is 7.5.7600.16385. Instead of crashing, this value should return in the verionInfo string. Any advice?

  • Overlay SVG diagrams on google maps

    - by ThibThib
    Hello I would like to add an overlay image on a google map. This image is a SVG file I have generated (python with svgfig). I am using the following code if (GBrowserIsCompatible()) { var map = new GMap2(document.getElementById("map_canvas")); map.setCenter(new GLatLng(48.8, 2.4), 12);     // ground overlay     var boundaries = new GLatLngBounds(new GLatLng(48.283188032632829, 1.9675270369830129), new GLatLng(49.187215000000002, 2.7771877478303999));     var oldmap = new GGroundOverlay("test.svg", boundaries); map.addControl(new GSmallMapControl()); map.addControl(new GMapTypeControl()); map.addOverlay(oldmap); } Surprisingly, it works with Safari 4, but it doesn't with Firefox (with Safari 3, the background is not transparent) Does anyone has an idea on how I could overlay a SVG ? Thanks PS1: I read some works like this or the source code of swa.ethz.ch/googlemaps, but it seems that they have to use javascript code to parse the SVG and add one by one all the elements (but I did not understood all the source...) PS2: The SVG is composed of different filled paths and circles, with transparency. If there is no solution to overlay my SVG, I can use 2 alternative solutions: rasterize the SVG convert the paths and circles in GPolygons But, I do not really like the 1st solution because of the poor quality of the bitmap and the time to generate it with antialiasing. And for the 2nd solutions, the arcs, ellipses and circles will have to be decomposed into small polylines. A lot of them will be necessary for a good result. But I have around 3000 arcs and circles to draw, so...

  • Is there something wrong with this code? AMFReader vs AMFWriter

    - by Triynko
    Something doesn't seem right about the source code for Flash Remoting's Date(AS3) <- DateTime(.NET) stream reader/writer methods, when it comes to handling UTC <- Local times. It seems to write the DateTime data fine, including a 64-bit representation as milliseconds elapsed since Jan 1, 1970, as well as a UTC offset. public void WriteDateTime(DateTime d) { this.BaseStream.WriteByte(11); DateTime time = new DateTime(0x7b2, 1, 1); long totalMilliseconds = (long)d.Subtract(time).TotalMilliseconds; long l = BitConverter.DoubleToInt64Bits((double)totalMilliseconds); this.WriteLong(l); int hours = TimeZone.CurrentTimeZone.GetUtcOffset(DateTime.Today).Hours; this.WriteShort(hours); } But when the data is read... it seems to be ignoring the short UTC offset value that was written, and appears to just discard it! private DateTime ReadDateValue() { long num2 = (long)this.ReadDouble(); DateTime time2 = new DateTime(0x7b2, 1, 1).AddMilliseconds((double)num2); int num3 = this.ReadInt16() / 60; //num3 is not used for anything! return time2; } Can anyone make sense of this? I also found some similar source code for AMFReader here, which has a ReadDateTime method, that seems to do something very similar... but goes on to use the UTC offset for something.

  • Problem with DSL and Business Rules creation in Drools

    - by jillika iyer
    Hi, I am using Eclipse with the Drools plugin to create rules. I want to create business rules and main aim is to try and provide the user a set of options which he can use to create rules. For eg:If an Apple can have only 3 colors: I want to provide an option like a drop down so that the user can know before hand which are the options he can use in his rules. Is it possible? I am creating a dsl but unable to still provide the above functionality for a business rule. I am having an error implementing a basic dsl also. The code to add the dsl is as follows in my RuleRunner class() InputStream ruleSource = RuleRunner.class.getClassLoader().getResourceAsStream("/Rule1.dslr"); InputStream dslSource = RuleRunner.class.getClassLoader().getResourceAsStream("/sample-dsl.dsl"); //Load the rules , using DSL addRulesToThisPackage.addPackageFromDrl( new InputStreamReader(ruleSource),new InputStreamReader(dslSource)); I have both the sample-dsl .dsl and Rule1.dslr in my working directory. Error encountered at adding the dsl to the package (last line) Error stack: Exception in thread "main" java.lang.NullPointerException at java.io.Reader.<init>(Unknown Source) at java.io.InputStreamReader.<init>(Unknown Source) at com.org.RuleRunner.loadRuleFile(RuleRunner.java:96) at com.org.RuleRunner.loadRules(RuleRunner.java:48) at com.org.RuleRunner.runStatelessRules(RuleRunner.java:109) at com.org.RulesTest.main(RulesTest.java:41) my dsl file has basic mapping as per the online documentations. The dsl rule I created is: expander sample-dsl.dsl rule "A status changes B status" when There is an A - has an address There is a B - has name then - print updated A and Aaddress End I have created DSL in eclipse. Is the code I added for it to be loaded to my package correct?? Or am I missing something???? It seems like my program is unable to find the dsl? Please help. Can you point me towards the right direction to create a user friendly business rule ?? Thanks. J

  • Can Git or Mercurial be set to bypass the local repository and go straight to the central one?

    - by Jian Lin
    Using Git or Mercurial, if the working directory is 1GB, then the local repository will be another 1GB (at least), residing normally in the same hard drive. And then when pushed to a central repository, there will be another 1GB. Can Git or Mercurial be set to use only a working directory and then a central repository, without having 3 copies of this 1GB data? (actually, when the central repository also update, then there are 4 copies of the same data... can it be reduced? In the SVN scenario, when there are 5 users, then there will be 6GB of data total. With Distributed Version Control, then there will be 12GB of data?)

  • Find out which row caused the error

    - by Felipe Fiali
    I have a big fat query that's written dynamically to integrate some data. Basically what it does is query some tables, join some other ones, treat some data, and then insert it into a final table. The problem is that there's too much data, and we can't really trust the sources, because there could be some errored or inconsistent data. For example, I've spent almost an hour looking for an error while developing using a customer's database because somewhere in the middle of my big fat query there was an error converting some varchar to datetime. It turned out to be that they had some sales dating '2009-02-29', an out-of-range date. And yes, I know. Why was that stored as varchar? Well, the source database has 3 columns for dates, 'Month', 'Day' and 'Year'. I have no idea why it's like that, but still, it is. But how the hell would I treat that, if the source is not trustable? I can't HANDLE exceptions, I really need that it comes up to another level with the original message, but I wanted to provide some more info, so that the user could at least try to solve it before calling us. So I thought about displaying to the user the row number, or some ID that would at least give him some idea of what record he'd have to correct. That's also a hard job because there will be times when the integration will run up to 80000 records. And in an 80000 records integration, a single dummy error message: 'The conversion of a varchar data type to a datetime data type resulted in an out-of-range datetime value' means nothing at all. So any idea would be appreciated. Oh I'm using SQL Server 2005 with Service Pack 3.

  • How do you handle files that can't support concurrent edits in Mercurial?

    - by Scott Whitlock
    I'm using Mercurial with TortoiseHg. Each developer has their own repositories, and there's one central repository on the server for synchronizing our changes. (This will sound lame, but we're using it to manage the source for a legacy VB6 project. Nothing we can do about that...) As has been pointed out elsewhere, there is a big problem in VB6 with merging the .frx (form resources) files. So code changes seem to merge fine, but if two developers both make changes at the same time in the form design view, we can't merge. I'm ok with disallowing concurrent edits, but of course the whole point of Mercurial is that it's distributed so there is no option to force a file to be locked before editing. I don't believe there's a Mercurial solution for this, so I'm wondering: other developers who are using Mercurial for version control, do you have some 3rd party tool that assists with locking files for editing in the cases where it's necessary? Did we make a mistake using Mercurial instead of something like SVN?

  • Subversion for version control

    - by Gabriel Parenza
    Hi, I am working on an application whose primary purpose would be to provide source control management. My idea is to use to SVNKit for file check-out and check-in. However, while working with SVNKit, I realised it does not have the speed I was looking for. For instance, whenever developers create a ChangeRequest, which can encompass change in 3-40 files, I have to create a directory structure distributed across 32 folders. Doing so takes around 50 seconds, Another instance is that after creating change request developers can add files to the request. Copying even a single file from Trunk to branch takes around 6-7 secs. My question is has anyone had experience like this and what did you do to improve the performance? Moreover, is my approach correct? NOTE: I am using "http" protocol and can't use "svn" protocol.

  • Raw types and subtyping

    - by Dmitrii
    We have generic class SomeClass<T>{ } We can write the line: SomeClass s= new SomeClass<String>(); It's ok, because raw type is supertype for generic type. But SomeClass<String> s= new SomeClass(); is correct to. Why is it correct? I thought that type erasure was before type checking, but it's wrong. From Hacker's Guide to Javac When the Java compiler is invoked with default compile policy it performs the following passes: parse: Reads a set of *.java source files and maps the resulting token sequence into AST-Nodes. enter: Enters symbols for the definitions into the symbol table. process annotations: If Requested, processes annotations found in the specified compilation units. attribute: Attributes the Syntax trees. This step includes name resolution, type checking and constant folding. flow: Performs data ow analysis on the trees from the previous step. This includes checks for assignments and reachability. desugar: Rewrites the AST and translates away some syntactic sugar. generate: Generates Source Files or Class Files. Generic is syntax sugar, hence type erasure invoked at 6 pass, after type checking, which invoked at 4 pass. I'm confused.

  • How can I create a SQL table using excel columns?

    - by Phsika
    I need to help to generate column name from excel automatically. I think that: we can do below codes: CREATE TABLE [dbo].[Addresses_Temp] ( [FirstName] VARCHAR(20), [LastName] VARCHAR(20), [Address] VARCHAR(50), [City] VARCHAR(30), [State] VARCHAR(2), [ZIP] VARCHAR(10) ) via C#. How can I learn column name from Excel? private void Form1_Load(object sender, EventArgs e) { ExcelToSql(); } void ExcelToSql() { string connectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Source\MPD.xlsm;Extended Properties=""Excel 12.0;HDR=YES;"""; // if you don't want to show the header row (first row) // use 'HDR=NO' in the string string strSQL = "SELECT * FROM [Sheet1$]"; OleDbConnection excelConnection = new OleDbConnection(connectionString); excelConnection.Open(); // This code will open excel file. OleDbCommand dbCommand = new OleDbCommand(strSQL, excelConnection); OleDbDataAdapter dataAdapter = new OleDbDataAdapter(dbCommand); // create data table DataTable dTable = new DataTable(); dataAdapter.Fill(dTable); // bind the datasource // dataBingingSrc.DataSource = dTable; // assign the dataBindingSrc to the DataGridView // dgvExcelList.DataSource = dataBingingSrc; // dispose used objects if (dTable.Rows.Count > 0) MessageBox.Show("Count:" + dTable.Rows.Count.ToString()); dTable.Dispose(); dataAdapter.Dispose(); dbCommand.Dispose(); excelConnection.Close(); excelConnection.Dispose(); }

  • Nothing gets displayed when debugging Microsoft Surface

    - by leftend
    I am trying to write my first Microsoft Surface application, and am doing the development on the Surface unit itself. I successfully re-created the quick "Photos" application that is shown on the PDC Video, however, now that I'm trying to create my own app - nothing actually shows up when I run it. I'm mainly just adding ScatterViews right now - and they show up fine in the designer, but as soon as I hit F5 - the shell is shown on the surface - but none of the ScatterViews show up. Here's my xaml code so far. Am I missing something?? <s:SurfaceWindow x:Class="SurfaceUITreeDemo.TreeDemo" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:s="http://schemas.microsoft.com/surface/2008" Title="WYITT Tree Demo" AllowsTransparency="False" Background="Beige"> <s:SurfaceWindow.Resources> <ImageBrush x:Key="WindowBackground" Stretch="None" Opacity="0.6" ImageSource="pack://application:,,,/Resources/TreeDemoBackground.jpg"/> </s:SurfaceWindow.Resources> <Grid Background="{StaticResource WindowBackground}" > <s:ScatterView Name="test"> <Image Source="C:\dev\Network-Alt-icon.png"/> </s:ScatterView> <s:ScatterView Height="100" Margin="456,160,348,0" Name="scatterView1" VerticalAlignment="Top" Background="Black"> <s:ScatterViewItem Height="100" Width="150"> <Image Source="C:\dev\Network-Alt-icon.png"/> </s:ScatterViewItem> <s:ScatterViewItem></s:ScatterViewItem> ScatterView </s:ScatterView> </Grid> </s:SurfaceWindow>
