  • Binding keys from specific device in X.org

    - by Michal Cihar
    I have a remote control for presentations, which generates Next/Prior key events in X.org (Page up/down). I'd like to use these for navigating in playlist (using MPD, but it probably does not matter). The problem is that I want to make this control work all the time (without application having focus) and I don't want to lose Page up/down functionality from normal keyboard. Is there some application which would allow me to bind actions to events from specific keyboard? Or is there simple way to implement such thing on my own?

  • Binding FontStyles and FontWeights to WPF ComboBox

    - by Haemoglobin
    I was just wondering if it would be possible to bind the list of available FontStyles and FontWeights to a ComboBox? For example, to bind the list of fonts to a combobox you can use: FontComboBox.ItemsSource = Fonts.SystemFontFamilies; Can I also have something for : FontStyleComboBox.ItemsSource = .... FontWeightComboBox.ItemsSource = .... ? Would it require reflection on the System.Windows.FontWeights and System.Windows.FontStyles classes or would there be an easier way than that? Thanks

  • XML\Jquery create listings based on user selection

    - by Sirius Mane
    Alright, so what I need to try and accomplish is having a static web page that will display information pulled from an XML document and render it to the screen without refreshing. Basic AJAX stuff I guess. The trick is, as I'm trying to think this through I keep coming into 'logical' barriers mentally. Objectives: -Have a chart which displays baseball team names, wins, losses, ties. In my XML doc there is a 'pending' status, so games not completed should not be displayed.(Need help here) -Have a selection list which allows you to select a team which is populated from XML doc. (done) -Upon selecting a particular team from the aforementioned selection list the page should display in a separate area all of the planned games for that team. Including pending. Basically all of the games associated with that team and the dates (which is included in the XML file). (Need help here) What I have so far: HTML\JS <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <link rel="stylesheet" href="batty.css" type="text/css" /> <meta http-equiv="Content-Type" content="text/html;

Any help right now would be great, I'm just banging my head against a wall. I'm trying to avoid using XSLT transforms because I absolutely despise XML and I'm not good with it. So I'd -like- to just use Javascript\PHP\etc with only a sprinkling of the necessary XML where possible..

  • WCF REST Question, Binding, Configuration

    - by Ethan McGee
    I am working on a WCF rest interface using json. I have wrapped the service in a windows service to host the service but I am now having trouble getting the service to be callable. I am not sure exactly what is wrong. The basic idea is that I want to host the service on a remote server so I want the service mapped to port localhost:7600 so that it can be invoked by posting data to [server_ip]:7600. The problem is most likely in the configuration file, since I am new to WCF and Rest I wasn't really sure what to type for the configuration so sorry if it's a total mess. I removed several chunks of code and comments to make it a little easier to read. These functions should have no bearing on the service since they call only C# functions. WCF Service Code using System; using System.Collections.Generic; using System.Linq; using System.ServiceModel; using System.ServiceModel.Activation; using System.ServiceModel.Web; using System.Text; namespace PCMiler_Connect { public class ZIP_List_Container { public string[] ZIP_List { get; set; } public string Optimized { get; set; } public string Calc_Type { get; set; } public string Cross_International_Borders { get; set; } public string Use_Kilometers { get; set; } public string Hazard_Level { get; set; } public string OK_To_Change_Destination { get; set; } } [ServiceContract] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)] public class PCMiler_Webservice { [WebInvoke(Method = "POST", UriTemplate = "", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json), OperationContract] public List<string> Calculate_Distance(ZIP_List_Container container) { return new List<string>(){ distance.ToString(), time.ToString() }; } } } XML Config File <?xml version="1.0" encoding="utf-8"?> <configuration> <system.serviceModel> <services> <service name="PCMiler_Connect.PCMiler_Webservice"> <endpoint address="" behaviorConfiguration="jsonBehavior" binding="webHttpBinding" bindingConfiguration="" contract="PCMiler_Connect.PCMiler_Webservice" /> <host> <baseAddresses> <add baseAddress="http://localhost:7600/" /> </baseAddresses> </host> </service> </services> <behaviors> <endpointBehaviors> <behavior name="jsonBehavior"> <enableWebScript/> </behavior> </endpointBehaviors> </behaviors> </system.serviceModel> </configuration> Service Wrapper using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Diagnostics; using System.Linq; using System.ServiceProcess; using System.ServiceModel; using System.Text; using System.Threading; namespace PCMiler_WIN_Service { public partial class Service1 : ServiceBase { ServiceHost host; public Service1() { InitializeComponent(); } protected override void OnStart(string[] args) { host = new ServiceHost(typeof(PCMiler_Connect.PCMiler_Webservice)); Thread thread = new Thread(new ThreadStart(host.Open)); } protected override void OnStop() { if (host != null) { host.Close(); host = null; } } } }

  • What does P mean in Sort(Expression<Func<T, P>> expr, ListSortDirection direction)?

    - by Grasshopper
    I am attempting to use the answer in post: How do you sort an EntitySet<T> to expose an interface so that I can sort an EntitySet with a Binding list. I have created the class below and I get the following compiler error: "The type or namespace 'P' could not be found (are you missing a using directive or assembly reference?). Can someone tell me what the P means and which namespace I need to include to get the method below to compile? I am very new to delegates and lamba expressions. Also, can someone confirm that if I create a BindingList from my EntitySet that any modifications I make to the BindingList will be made to the EntitySet? Basically, I have an EntitySet that I need to sort and make changes to. Then, I will need to persist these changes using the original Entity that the BindingList came from. public class EntitySetBindingWrapper<T> : BindingList<T> { public EntitySetBindingWrapper(BindingList<T> root) : base(root) { } public void Sort(Expression<Func<T, P>> expr, ListSortDirection direction) { if (expr == null) base.RemoveSortCore(); MemberExpression propExpr = expr as MemberExpression; if (propExpr == null) throw new ArgumentException("You must provide a property", "expr"); PropertyDescriptorCollection descriptorCol = TypeDescriptor.GetProperties(typeof(T)); IEnumerable<PropertyDescriptor> descriptors = descriptorCol.Cast<PropertyDescriptor>(); PropertyDescriptor descriptor = descriptors.First(pd => pd.Name == propExpr.Member.Name); base.ApplySortCore(descriptor, direction); } }

  • How to write PowerShell code part 1 (Using external xml configuration file)

    - by ybbest
    In this post, I will show you how to use external xml file with PowerShell. The advantage for doing so is that you can avoid other people to open up your PowerShell code to make the configuration changes; instead all they need to do is to change the xml file. I will refactor my site creation script as an example; you can download the script here and refactored code here. 1. As you can see below, I hard code all the variables in the script itself. $url = "http://ybbest" $WebsiteName = "Ybbest" $WebsiteDesc = "Ybbest test site" $Template = "STS#0" $PrimaryLogin = "contoso\administrator" $PrimaryDisplay = "administrator" $PrimaryEmail = "[email protected]" $MembersGroup = "$WebsiteName Members" $ViewersGroup = "$WebsiteName Viewers" 2. Next, I will show you how to manipulate xml file using PowerShell. You can use the get-content to grab the content of the file. [xml] $xmlconfigurations=get-content .\SiteCollection.xml 3. Then you can set it to variable (the variable has to be typed [xml] after that you can read the content of the xml content, PowerShell also give you nice IntelliSense by press the Tab key. [xml] $xmlconfigurations=get-content .\SiteCollection.xml $xmlconfigurations.SiteCollection $xmlconfigurations.SiteCollection.SiteName 4. After refactoring my code, I can set the variables using the xml file as below. #Set the parameters $siteInformation=$xmlinput.SiteCollection $url = $siteInformation.URL $siteName = $siteInformation.SiteName $siteDesc = $siteInformation.SiteDescription $Template = $siteInformation.SiteTemplate $PrimaryLogin = $siteInformation.PrimaryLogin $PrimaryDisplay = $siteInformation.PrimaryDisplayName $PrimaryEmail = $siteInformation.PrimaryLoginEmail $MembersGroup = "$WebsiteName Members" $ViewersGroup = "$WebsiteName Viewers"

  • Linq To SQL: Behaviour for table field which is NotNull and having Default value or binding

    - by kaushalparik27
    I found this something interesting while wandering over community which I would like to share. The post is whole about: DBML is not considering the table field's "Default value or Binding" setting which is a NotNull. I mean the field which can not be null but having default value set needs to be set IsDbGenerated = true in DBML file explicitly.Consider this situation: There is a simple tblEmployee table with below structure: The fields are simple. EmployeeID is a Primary Key with Identity Specification = True with Identity Seed = 1 to autogenerate numeric value for this field. EmployeeName and their EmailAddress to store in rest of 2 fields. And the last one is "DateAdded" with DateTime datatype which doesn't allow NULL but having Default Value/Binding with "GetDate()". That means if we don't pass any value to this field then SQL will insert current date in "DateAdded" field.So, I start with a new website, add a DBML file and dropped the said table to generate LINQ To SQL context class. Finally, I write a simple code snippet to insert data into the tblEmployee table; BUT, I am not passing any value to "DateAdded" field. Because I am considering SQL Server's "Default Value or Binding (GetDate())" setting to this field and understand that SQL will insert current date to this field.        using (TestDatabaseDataContext context = new TestDatabaseDataContext())        {            tblEmployee tblEmpObjet = new tblEmployee();            tblEmpObjet.EmployeeName = "KaushaL";            tblEmpObjet.EmployeeEmailAddress = "[email protected]";            context.tblEmployees.InsertOnSubmit(tblEmpObjet);            context.SubmitChanges();        }Here comes the twist when application give me below error:  This is something not expecting! From the error it clearly depicts that LINQ is passing NULL value to "DateAdded" Field while according to my understanding it should respect Sql Server's "Default value or Binding" setting for this field. A bit googling and I found very interesting related to this problem.When we set Primary Key to any field with "Identity Specification" Property set to true; DBML set one important property "IsDbGenerated=true" for this field. BUT, when we set "Default Value or Biding" property for some field; we need to explicitly tell the DBML/LINQ to let it know that this field is having default binding at DB side that needs to be respected if I don't pass any value. So, the solution is: You need to explicitly set "IsDbGenerated=true" for such field to tell the LINQ that the field is having default value or binding at Sql Server side so, please don't worry if i don't pass any value for it.You can select the field and set this property from property window in DBML Designer file or write the property in DBML.Designer.cs file directly. I have attached a working example with required table script with this post here. I hope this would be helpful for someone hunting for the same. Happy Discovery!

  • Line-length-tolerant XML diff

    - by Jon Skeet
    I've looked at the answers to this question, and unfortunately none of them has helped me so far. Not to beat about the bush, the second edition of C# in Depth is now in copy edit. I want to be able to see what the copy editor's done really easily, so I can reject or accept his changes. We're using a modified form of docbook, but I'm happy enough looking at the raw XML source. All fine so far - except that when the copy editor makes a change, that can change the line wrapping. So something that used to read: <para>Foo bar baz second line</para> now reads <para>Foo bar grontle baz second line</para> Now the real change here is the insertion of "grontle". I don't care that "baz" has moved from the first line to the second line... but all the diff tools I've seen do. I realise that one option would be to reformat the whole document (or possibly just whole paragraphs) into single lines... but that's then really hard to read, because diff tools don't wrap when they're displaying. I'm sure I can manage with the tools I've got, but if anyone knows of anything better, I'd be really glad to hear about it. I suspect my publishers would too :) (I've included the Windows tag here because I'd really need it to be available on Windows. I'd like to hear about any non-Windows software too, but only in case I could help to build it on Windows :)

  • XNA 4.0: Problem with loading XML content files

    - by 200
    I'm new to XNA so hopefully my question isn't too silly. I'm trying to load content data from XML. My XML file is placed in my Content project (the new XNA 4 thing), called "Event1.xml": <?xml version="1.0" encoding="utf-8" ?> <XnaContent> <Asset Type="MyNamespace.Event"> // error on this line <name>1</name> </Asset> </XnaContent> My "Event" class is placed in my main project: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Xml.Linq; namespace MyNamespace { public class Event { public string name; } } The XML file is being called by my main game class inside the LoadContent() method: Event temp = Content.Load<Event>("Event1"); And this is the error I'm getting: There was an error while deserializing intermediate XML. Cannot find type "MyNamespace.Event" I think the problem is because at the time the XML is being evaluated, the Event class has not been established because one file is in my main project while the other is in my Content project (being a XNA 4.0 project and such). I have also tried changing the build action of the xml file from compile to content; however the program would then not be able to find the file and would give this other warning: Project item 'Event1.xml' was not built with the XNA Framework Content Pipeline. Set its Build Action property to Compile to build it. Any suggestions are appreciated. Thanks.

  • SQL SERVER – Quiz and Video – Introduction to Discovering XML Data Type Methods

    - by pinaldave
    This blog post is inspired from SQL Interoperability Joes 2 Pros: A Guide to Integrating SQL Server with XML, C#, and PowerShell – SQL Exam Prep Series 70-433 – Volume 5. [Amazon] | [Flipkart] | [Kindle] | [IndiaPlaza] This is follow up blog post of my earlier blog post on the same subject - SQL SERVER – Introduction to Discovering XML Data Type Methods – A Primer. In the article we discussed various basics terminology of the XML. The article further covers following important concepts of XML. What are XML Data Type Methods The query() Method The value() Method The exist() Method The modify() Method Above five are the most important concepts related to XML and SQL Server. There are many more things one has to learn but without beginners fundamentals one can’t learn the advanced  concepts. Let us have small quiz and check how many of you get the fundamentals right. Quiz 1.) Which method returns an XML fragment from the source XML? query( ) value( ) exist( ) modify( ) All of them Only query( ) and value( ) 2.) Which XML data type method returns a “1” if found and “0” if the specified XPath is not found in the source XML? query( ) value( ) exist( ) modify( ) All of them Only query( ) and value( ) 3.) Which XML data type method allows you to pick the data type of the value that is returned from the source XML? query( ) value( ) exist( ) modify( ) All of them Only query( ) and value( ) 4.) Which method will not work with a SQL SELECT statement? query( ) value( ) exist( ) modify( ) All of them Only query( ) and value( ) Now make sure that you write down all the answers on the piece of paper.

  • Is there a free XML viewer to do "pivot tables"

    - by FumbleFingers
    I have an *.xml file on a PC running Windows XP, with a structure something like... <movies id="my movies" <movie name="Unforgiven" <people star="Clint Eastwood" director="Clint Eastwood"/> </movie> <movie name="A Fistful of Dollars" <people star="Clint Eastwood" director="Sergio Leone"/> </movie> <movie name="J Edgar" <people star="Leonardo DiCaprio" director="Clint Eastwood"/> </movie> </movies> I want to open this file in a viewer utility which will show one line per movie, filtered by a condition such as director="Clint Eastwood", including the relevant value for movie name on each line. Note - that's just an example. My actual file has thousands of lines, each possibly several hundred bytes long, and there are many more levels and named values. The important thing is I want to apply a filter for a specified value of some field at some level. And I want to see one line for every case where that value occurs, showing the values for any fields I specify, even if they're stored at higher levels. I may be mistaken in saying what I want is a "pivot table" - I don't know what I should call it.

  • Loading XML file containing leading zeros with SSIS preserving the zeros

    - by Compudicted
    Visiting the MSDN SQL Server Integration Services Forum oftentimes I could see that people would pop up asking this question: “why I am not able to load an element from an XML file that contains zeros so the leading/trailing zeros would remain intact?”. I started to suspect that such a trivial and often-required operation perhaps is being misunderstood by the developer community. I would also like to add that the whole state of affairs surrounding the XML today is probably also going to be increasingly affected by a motion of people who dislike XML in general and many aspects of it as XSD and XSLT invoke a negative reaction at best. Nevertheless, XML is in wide use today and its importance as a bridge between diverse systems is ever increasing. Therefore, I deiced to write up an example of loading an arbitrary XML file that contains leading zeros in one of its elements using SSIS so the leading zeros would be preserved keeping in mind the goal on simplicity into a table in SQL Server database. To start off bring up your BIDS (running as admin) and add a new Data Flow Task (DFT). This DFT will serve as container to adding our XML processing elements (besides, the XML Source is not available anywhere else other than from within the DFT). Double-click your DFT and drag and drop the XMS Source component from the Tool Box’s Data Flow Sources. Now, let the fun begin! Being inspired by the upcoming Christmas I created a simple XML file with one set of data that contains an imaginary SSN number of Rudolph containing several leading zeros like 0000003. This file can be viewed here. To configure the XML Source of course it is quite intuitive to point it to our XML file, next what the XML source needs is either an embedded schema (XSD) or it can generate one for us. In lack of the one I opted to auto-generate it for me and I ended up with an XSD that looked like: <?xml version="1.0"?> <xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="XMasEvent"> <xs:complexType> <xs:sequence> <xs:element minOccurs="0" name="CaseInfo"> <xs:complexType> <xs:sequence> <xs:element minOccurs="0" name="ID" type="xs:unsignedByte" /> <xs:element minOccurs="0" name="CreatedDate" type="xs:unsignedInt" /> <xs:element minOccurs="0" name="LastName" type="xs:string" /> <xs:element minOccurs="0" name="FirstName" type="xs:string" /> <xs:element minOccurs="0" name="SSN" type="xs:unsignedByte" /> <!-- Becomes string -- > <xs:element minOccurs="0" name="DOB" type="xs:unsignedInt" /> <xs:element minOccurs="0" name="Event" type="xs:string" /> <xs:element minOccurs="0" name="ClosedDate" /> </xs:sequence> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> As an aside on the XML file: if your XML file does not contain the outer node (<XMasEvent>) then you may end up in a situation where you see just one field in the output. Now please note that the SSN element’s data type was chosen to be of unsignedByte (and this is for a reason). The reason is stemming from the fact all our figures in the element are digits, this is good, but this is not exactly what we need, because if we will attempt to load the data with this XSD then we are going to either get errors on the destination or most typically lose the leading zeros. So the next intuitive choice is to change the data type to string. Besides, if a SSIS package was already created based on this XSD and the data type change was done thereafter, one should re-set the metadata by right-clicking the XML Source and choosing “Advanced Editor” in which there is a refresh button at the bottom left which will do the trick. So far so good, we are ready to load our XML file, well actually yes, and no, in my experience typically some data conversion may be required. So depending on your data destination you may need to tweak the data types targeted. Let’s add a Data Conversion Task to our DFT. Your package should look like: To make the story short I only will cover the SSN field, so in my data source the target SQL Table has it as nchar(10) and we chose string in our XSD (yes, this is a big difference), under such circumstances the SSIS will complain. So will go and manipulate on the data type of SSN by making it Unicode String (DT_WSTR), World String per se. The conversion should look like: The peek at the Metadata: We are almost there, now all we need is to configure the destination. For simplicity I chose SQL Server Destination. The mapping is a breeze, F5 and I am able to insert my data into SQL Server now! Checking the zeros – they are all intact!

  • SQL Server and the XML Data Type : Data Manipulation

    The introduction of the xml data type, with its own set of methods for processing xml data, made it possible for SQL Server developers to create columns and variables of the type xml. Deanna Dicken examines the modify() method, which provides for data manipulation of the XML data stored in the xml data type via XML DML statements.

  • Silverlight Binding with multiple collections

    - by George Evjen
    We're designing some sport specific applications. In one of our views we have a gridview that is bound to an observable collection of Teams. This is pretty straight forward in terms of getting Teams bound to the GridView. <telerik:RadGridView Grid.Row="0" Grid.Column="0" x:Name="UsersGrid" ItemsSource="{Binding TeamResults}" SelectedItem="{Binding SelectedTeam, Mode=TwoWay}"> <telerik:RadGridView.Columns> <telerik:GridViewDataColumn Header="Name/Group" DataMemberBinding="{Binding TeamName}" MinWidth="150"></telerik:GridViewDataColumn> </telerik:RadGridView.Columns> </telerik:RadGridView> We use the observable collection of teams as our items source and then bind the property of TeamName to the first column. You can set the binding to mode=TwoWay, we use a dialog where we edit the selected item, so our binding here is not set to two way. The issue comes when we want to bind to a property that has another collection in it. To continue on our code from above, we have an observable collection of teams, within that collection we have a collection of KeyPeople. We get this collection using RIA Serivces with the code below. return _TeamsRepository.All().Include("KeyPerson"); Here we are getting all the teams and also including the KeyPerson entity. So when we are done with our Load we will end up with an observable collection of Teams with a navigation property / entity of KeyPerson. Within this KeyPerson entity is a list of people associated with that particular team. We want to display the head coach from this list of KeyPersons. This list currently has a list of ten or more people that are bound to this team, but we just want to display the Head Coach in the column next to team name. The issue becomes how do we bind to this included entity? I have found about three different ways to solve this issue. The way that seemed to fit us best is to utilize the features within RIA Services. We can create client side properties that will do the work for us. We will create in the client side library a partial class of Team. We will end up in our library a file that is Team.shared.cs. The code below is what we will put into our partial team class. public KeyPerson Coach        {            get            {                if (this.KeyPerson != null && this.KeyPerson.Any())                { return this.KeyPerson.Where(x => x.RelationshipType == “HeadCoach”).FirstOrDefault(); }                 return null;            }        } We will return just the person that is the Head Coach and then be able to bind that and any other additional properties that we need. <telerik:GridViewDataColumn Header="Coach" DataMemberBinding="{Binding Coach.Name}" MinWidth="150"></telerik:GridViewDataColumn> There are other ways that we could have solved this issue but we felt that creating a partial class through RIA Services best suited our needs.

  • SQL to XML open data made simple

    - by drrwebber
    The perennial question for people is how to easily generate XML from SQL table content?  The latest CAM Editor release really tackles this head on by providing a powerful and simple toolset.  Firstly you can visually browse your SQL tables and then drag and drop from columns and tables into the XML structure editor.   This gives you a code-free method of describing the transformation you require.  So you do not need to know about the vagaries of XML and XSD schema syntax. Second you can map directly into existing industry domain XML exchange structures in the XML visual editor, again no need to wrestle with XSD schema, you have WYSIWYG visual control over what your output will look like. If you do not have a target XML structure and need to build one from scratch, then the CAM Editor makes this simple.  Switch the SQL viewer into designer mode, then take your existing SQL table and drag and drop it into the XML structure editor.  Automatically the XML wizard tool will take your SQL column names and definitions and create equivalent XML for you and insert the mappings. Simply save the structure template, and run the Open Data generator menu option, and your XML is built for you. Completely code-free template driven development. To see this in action, see our video demonstration links and then download the tools and samples and try it yourself.

  • Is there a simple, flat, XML-based query-able data storage solution? [closed]

    - by alex gray
    I have been in long pursuit of an XML-based query-able data store, and despite continued searches and evaluations, I have yet to find a solution that meets the my needs, which include: Data is wholly contained within XML nodes, in flat text files. There is a "native" - or at least unobtrusive - method with which to perform Create/Read/Update/Delete (CRUD) operations onto the "schema". I would consider access via http, XHR, javascript, PHP, BASH, or PERL to be unobtrusive, dependent on the complexity of the set of dependencies. Server-side file-system reads and writes. A client-side interface element, accessible in any browser without a plug-in. Some extra, preferred (but optional) requirements include: Respond to simple SQL, or similarly syntax queries. Serve the data on a bare bones https server, with no "extra stuff", either via XMLHTTPRequest, HTTP proper, or JSON. A few thoughts: What I'm looking for may be possible via some Java server implementations, but for the sake of this question, please do not suggest that - unless it meets ALL the requirements. Java, especially on the client-side is not really an option, nor is it appealing from a development viewpoint.* I know walking the filesystem is a stretch, and I've heard it's possible with XPATH or XSLT, but as far as I know, that's not ready for primetime, nor even yet a recommendation. However the ability to recursively traverse the filesystem is needed for such a system to be of useful facility. At this point, I have basically implemented what I described via, of all things, CGI and Bash, but there has to be an easier way. Thoughts?
