  • Move Data into the Grid for Scalable, Predictable Response Times

    - by JuergenKress
    CloudTran is pleased to introduce the availability of the CloudTran Transaction and Persistence Manager for creating scalable, reliable data services on the Oracle Coherence In-Memory Data Grid (IMDG). Use of IMDG architectures has been key to handling today’s web-scale loads because it eliminates database latency by storing important and frequently access data in memory instead of on disk. The CloudTran product lets developers easily use an IMDG for full ACID-compliant transactions without having to be concerned about the location or spread of data. The system has its own implementation of fast, scalable distributed transactions that does NOT depend on XA protocols but still guarantees all ACID properties. Plus, CloudTran asynchronously replicates data going into the IMDG to back-end datastores and back-up data centers, again ensuring ACID properties. CloudTran can be accessed through Java Persistence API (JPA via TopLink Grid) and now, through a new Low-Level API, or LLAPI. This is ideal for use in SOA applications that need data reliability, high availability, performance, and scalability. Still in limited beta release, the LLAPI gives developers the ability to use standard put/remove logic available in Coherence and then wrap logic with simple Spring annotations or XML+AspectJ to start transactions. An important feature of LLAPI is the ability to join transactions. This is a common outcome for SOA applications that need to reduce network traffic by aggregating data into single cache entries and then doing SOA service processing in the node holding the data. This results in the need to orchestrate transaction processing across multiple service calls. CloudTran has the capability to handle these “multi-client” transactions at speed with no loss in ACID properties. Developing software around an IMDG like Oracle Coherence is an important choice for today’s web-scale applications and services. But this introduces new architectural considerations to maintain scalability in light of increased network loads and data movement. Without using CloudTran, developers are faced with an incredibly difficult task to ensure data reliability, availability, performance, and scalability when working with an IMDG. Working with highly distributed data that is entirely volatile while stored in memory presents numerous edge cases where failures can result in data loss. The CloudTran product takes care of all of this, leaving developers with the confidence and peace of mind that all data is processed correctly. For those interested in evaluating the CloudTran product and IMDGs, take a look at this link for more information: http://www.CloudTran.com/downloadAPI.php, or, send your questions to [email protected].

  • Random enemy placement on a 2d grid

    - by Robb
    I want to place my items and enemies randomly (or as randomly as possible). At the moment I use XNA's Random class to generate a number between 800 for X and 600 for Y. It feels like enemies spawn more towards the top of the map than in the middle or bottom. I do not seed the generator, maybe that is something to consider. Are there other techniques described that can improve random enemy placement on a 2d grid?

  • Dynamically Create Different Controls on Grid view as a Single Column

    Usually we use Grid view control to display either a static or dynamic data (ie., in row column format). We may use either datatable , dataview , dataset to display records. Here is also the same but quit different to create more than one control in gridview as a single column. We may add such a set of controls for more than one time depends on the need of the user. Here is the code for you dear friends....

  • WPF ListView as a DataGrid – Part 3

    - by psheriff
    I have had a lot of great feedback on the blog post about turning the ListView into a DataGrid by creating GridViewColumn objects on the fly. So, in the last 2 parts, I showed a couple of different methods for accomplishing this. Let’s now look at one more and that is use Reflection to extract the properties from a Product, Customer, or Employee object to create the columns. Yes, Reflection is a slower approach, but you could create the columns one time then cache the View object for re-use. Another potential drawback is you may have columns in your object that you do not wish to display on your ListView. But, just because so many people asked, here is how to accomplish this using Reflection.   Figure 1: Use Reflection to create GridViewColumns. Using Reflection to gather property names is actually quite simple. First you need to pass any type (Product, Customer, Employee, etc.) to a method like I did in my last two blog posts on this subject. Below is the method that I created in the WPFListViewCommon class that now uses reflection. C#public static GridView CreateGridViewColumns(Type anyType){  // Create the GridView  GridView gv = new GridView();  GridViewColumn gvc;   // Get the public properties.  PropertyInfo[] propInfo =          anyType.GetProperties(BindingFlags.Public |                                BindingFlags.Instance);   foreach (PropertyInfo item in propInfo)  {    gvc = new GridViewColumn();    gvc.DisplayMemberBinding = new Binding(item.Name);    gvc.Header = item.Name;    gvc.Width = Double.NaN;    gv.Columns.Add(gvc);  }   return gv;} VB.NETPublic Shared Function CreateGridViewColumns( _  ByVal anyType As Type) As GridView  ' Create the GridView   Dim gv As New GridView()  Dim gvc As GridViewColumn   ' Get the public properties.   Dim propInfo As PropertyInfo() = _    anyType.GetProperties(BindingFlags.Public Or _                          BindingFlags.Instance)   For Each item As PropertyInfo In propInfo    gvc = New GridViewColumn()    gvc.DisplayMemberBinding = New Binding(item.Name)    gvc.Header = item.Name    gvc.Width = [Double].NaN    gv.Columns.Add(gvc)  Next   Return gvEnd Function The key to using Relection is using the GetProperties method on the type you pass in. When you pass in a Product object as Type, you can now use the GetProperties method and specify, via flags, which properties you wish to return. In the code that I wrote, I am just retrieving the Public properties and only those that are Instance properties. I do not want any static/Shared properties or private properties. GetProperties returns an array of PropertyInfo objects. You can loop through this array and build your GridViewColumn objects by reading the Name property from the PropertyInfo object. Build the Product Screen To populate the ListView shown in Figure 1, you might write code like the following: C#private void CollectionSample(){  Product prod = new Product();   // Setup the GridView Columns  lstData.View =      WPFListViewCommon.CreateGridViewColumns(typeOf(Product));  lstData.DataContext = prod.GetProducts();} VB.NETPrivate Sub CollectionSample()  Dim prod As New Product()   ' Setup the GridView Columns  lstData.View = WPFListViewCommon.CreateGridViewColumns( _       GetType(Product))  lstData.DataContext = prod.GetProducts()End Sub All you need to do now is to pass in a Type object from your Product class that you can get by using the typeOf() function in C# or the GetType() function in VB. That’s all there is to it! Summary There are so many different ways to approach the same problem in programming. That is what makes programming so much fun! In this blog post I showed you how to create ListView columns on the fly using Reflection. This gives you a lot of flexibility without having to write extra code as was done previously. NOTE: You can download the complete sample code (in both VB and C#) at my website. http://www.pdsa.com/downloads. Choose Tips & Tricks, then "WPF ListView as a DataGrid – Part 3" from the drop-down.

  • Possible to register Selenium RC's with the Hudson Selenium Grid Hub w/o the RC's being slaves in th

    - by Rodreegez
    I am trying to get Hudson to run my ruby based selenium tests. I have installed the Selenium Grid plugin, but I don't want to have the RC's running as slaves in a Hudson cluster. The reason for this is I don't want to waste the next six years of my life trying to configure each of my projects in various Windows environments. Hudson currently pulls each project from Github and builds it just fine. With a regular Selenium Grid setup, I am able to edit the grid_configuration.yml file to represent the various environments I wish to tests against, then pass environment variables to the rake task that runs the test i.e. which browser/platfom to run on and the URL of the application under test -- usually a port on the hub machine running in a specific environment. In this way, the machines on which the RC's run don't need to know anything about the source code of my apps, they just need to have selenium-grid installed and have registered with the hub. Is there a way of elegantly emulating this with Hudson?

    Hi, Can you please help me understand the significant differences between Cloud Computing and Grid Computing ? What are the precise definations and target application domains for both ? I'm looking for conceptual insights along with technicalities. Like Windows Azure is a Cloud OS, do we have anytihng such for Grid Computing ? In past I did work on distributed and parallel computing and I used the librariries like PVM and MPI for processing distribution. Out of curiosity I wanted to know If Grid Computing is distributed computing extended over internet ?

  • In C#, how do you send a refresh/repaint message to a WPF grid or canvas?

    - by xarzu
    How do you send a refresh message to a WPF grid or canvas? In other words, I have noticed while in debug mode, I can write code that sends a line to the display and then, if that line is not right, I can adjust it -- but the previous line is still there. Now, the code I am writing sends information to the display based on what the user clicks. So this must mean that the display is not refreshed each time a new set of lines and boxes and text goes to the grid or canvas in WPF. Using C# code, how do you send a refresh/repaint message to a WPF grid or canvas?

  • How to read and set a value of a specific cell in an ExtJS Grid ?

    - by Lou
    Hello, I am beginning with ExtJS. I am trying to read a value from a cell that is selected I use an EditorGrid and the store looking like that : my_store = new Ext.data.JsonStore({ root: 'topics', totalProperty: 'totalCount', idProperty: 'details_id', fields: [ {name : 'index', type : 'int'}, {name : 'inactive', type : 'int'}, {name : 'c_1', type : 'string'}, {name : 'c_2', type : 'string'}, {name : 'c_3', type : 'string'}, {name : 'c_4', type : 'string'} ], proxy: new Ext.data.ScriptTagProxy({ url: 'my_proxy_url' }) }); As of now, this is what I use to retrieve the rows and columns of the selected cell : var column = grid.getSelectionModel().selection.cell[0]; var row = grid.getSelectionModel().selection.cell[1]; How can I read the value of a selected cell in the grid and change this value ?

  • Adding a new row in between rows in a grid view.

    - by SARAVAN
    I have an ASP .net grid view. It has some template columns like a command button, a text box, and a dropdown control. When I click the command button, a new row needs to be inserted below the current row (from where I hit the command button). If I have rows 1 and 2 and I hit the command button in row1 a new row needs to be inserted between rows 1 and 2 Now in the new row I should be able to select values from dropdown and enter some value in a text box and finally hit my save button. (Which should work fine as I am expecting) The grid view is bound to some data source say for instance a datatable for now. Oneway that I could think about is when Command button is clicked, I can add a new row to the datatable in my server side code and rebind the grid. But I am not sure that, from a UI perspective how I can make sure that the new row goes exactly below the row from where I hit the command button. Any thoughts or comments?

What exactly I want to do is in the datagridtemplatecolumn for others I want to display the usernames that are not in CurrentUsername, but they have the same program Id as the CurrentUsername. Please do let me know if there is another way that i can make this work, instead of using a dependencyproperty, althouht for testing I did put a textblock below datagrid, and it works perfectly fine.. Help!

  • DataGrid row and MVVM

    - by Titan
    Hi, I have a wpf datagrid with many rows, each row has some specific behaviors like selection changed of column 1 combo will filter column 2 combo, and what is selected in row 1 column 1 combo cannot be selected in row 2 column 1 combo, etc... So I am thinking of having a view model for the main datagrid, and another for each row. Is that a good MVVM implementation? It is so that I can handle each row's change event effectively. Question is, how do I create "each row" as a user control view? within the datagrid. I want to implement something like this: <TreeView Padding="0,4,12,0"> <controls:CommandTreeViewItem Header="Sales Orders" Command="{Binding SelectViewModelCommand}" CommandParameter="Sales Orders"/> </TreeView> Where instead of a TreeView I want a datagrid, and instead of controls:CommandTreeViewItem a datagrid row in WPF. Thanks in advance.

  • Datagrid for Symfony?

    - by Stick it to THE MAN
    I want to use a datagrid in one of my modules (Symfony 1.3, Propel ORM). I have spent a while searching the web, but everything I found expects a direct connection to teh db (mySQL) or is otherwise unsuitable. I found the datagrid plugin (http://symfony.swisscenter.com/datagrid/exemples), but the documentation/examples are in French - and I'm not too keen on learning French just for the sake of using the plugin - besides, if all the users are French speakers, then it will be difficult to get support/help if/when I do hget stuck. So my questions are: Is anyone aware of a good (PHP) datagrid component that I can use with SF? Is anyone out there (English speaker), using the SF datagrid plugin?

  • Change Rectangle Fill Based on ColumnWidth of a grid

    Essentially i want to do as the title says, if the columnwidth is .50 then the rectangle should be red, if it's .75 then it should be amber, and if it's 1 then it should be green. I thought I could achieve this with DataTriggers but for some reason I am getting "Object Reference Not Set To An Instance Of An Object" error, here is my code, am I missing something here? FYI the width property will be changed in the backend through a timer_tick event. <Grid x:Name="Grid1" Width="300" Height="30"> <Grid.ColumnDefinitions> <ColumnDefinition x:Name="MyColumn1" Width=".50*"></ColumnDefinition> <ColumnDefinition x:Name="MyColumn2" Width=".50*"></ColumnDefinition> </Grid.ColumnDefinitions> <Grid.Triggers> <DataTrigger Binding="{Binding ElementName=MyColumn1,Path=Width}" Value=".50*"> <Setter TargetName="rect" Property="Fill" Value="Red"></Setter> </DataTrigger> <DataTrigger Binding="{Binding ElementName=MyColumn1,Path=Width}" Value=".75*"> <Setter TargetName="rect" Property="Fill" Value="Yellow"></Setter> </DataTrigger> <DataTrigger Binding="{Binding ElementName=MyColumn1,Path=Width}" Value="1"> <Setter TargetName="rect" Property="Fill" Value="Green"></Setter> </DataTrigger> </Grid.Triggers> <Rectangle x:Name="rect" Grid.Column="0" HorizontalAlignment="Stretch"></Rectangle> <Rectangle Grid.Column="1" Fill="Blue"></Rectangle> </Grid>
