  • What is the best way to read and write cXML documents in C# ?

    - by tetranz
    I know this is a vague open ended question. I'm hoping to get some general direction. I need to add cXML punchout to an ASP.NET C# site / application. This is replacing something that I wrote years ago in ColdFusion. I'm a reasonably experienced C# developer but I haven't done much with XML. There seems to be lots of different options for processing XML in .NET. Here's the open ended question: Assuming that I have an XML document in some form, eg a file or a string, what is the best way to read it into my code? I want to get the data and then query databases etc. The cXML document size and our traffic volumes are easily small enough so that loading the a cXML document into memory is not a problem. Should I: 1) Manually build classes based on the dtd and use the XML Serializer? 2) Use a tool to generate classes. There are sample cXML files downloadable from Ariba.com. I tried xsd.exe to generate an xsd and then xsd.exe /c to generate classes. When I try to deserialize I get errors because there seems to be "confusion" around whether some elements should be single values or arrays. I tried the CodeXS online tool but that gives errors in it's log and errors if I try to deserialize a sample document. 2) Create a dataset and ReadXml()? 3) Create a typed dataset and ReadXml()? 4) Use Linq to XML. I often use Linq to Objects so I'm familiar with Linq in general but I'm struggling to see what it gives me in this situation. 5) Some other means. I guess I need to improve my understanding of XML in general but even so ... am I missing some obvious way of doing this? In the old ColdFusion site I found a free component ("tag") which basically ignored any schema and read the XML into a "structure" which is essentially a series of nested hash tables which was then easy to read in code. That was probably quite sloppy but it worked. I also need to generate XML files from my C# objects. Maybe Linq to XML will be good for that. I could start with a default "template" document and manipulate it before saving. Thanks for any pointers ...

  • How to play small sound file continuously in Silverlight?

    - by ash
    Hello, I have two questions regarding Silverlight's SoundPlay action and properties. My scenario is like: I have two story board: The first story board has an image and a sound file; when the silverlight application gets loaded, the sound starts to play automatically, but if someone clicks the image, the sound file will stop and the second storyboard will start with a new sound file. 1) My first question is how to stop the first sound file of first story board when the second story board starts with the second sound file. 2) My second question is how to play a sound file continuously; for example, in Silverlight we can play a story board continuously with RepeatBehavior="Forever"; but I cannot find a way to play my 10 second sound file forever or continuously. Note: I have attached a small XAML file to show what I am talking about; I am also stating that if instead of an image file, if there were a button, then I can stop the first music file after I click the button and start my second story board with a new sound file, but I would like to use image file instead of a button. Is it possible? If it is, how to do it? Therefore, please answer my following two questions or give big hint or website tutorial links on 1) How to stop the first sound file of first story board when the second story board starts with the second sound file ( When the clickable element is an image instead of a button) 2) How to play a 10 second sound file continuously? ............Code Snippet...................... XAML ............ <Grid x:Name="LayoutRoot" Background="Red"> <Button HorizontalAlignment="Left" Margin="212,0,0,111" VerticalAlignment="Bottom" Width="75" Content="Button" Click="onClick"/> <MediaElement x:Name="sound2_mp3" Height="0" HorizontalAlignment="Left" Margin="105,230,0,0" VerticalAlignment="Top" Width="0" Source="/sound2.mp3" Stretch="Fill"/> <MediaElement x:Name="sound1_mp1" Height="0" HorizontalAlignment="Left" Margin="190,164,0,0" VerticalAlignment="Top" Width="0" Source="/sound1.mp3" Stretch="Fill" AutoPlay="False"/> </Grid> ..................................................................................................................................................................................................................... using System; using System.Windows; using System.Windows.Controls; using System.Windows.Documents; using System.Windows.Ink; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Animation; using System.Windows.Shapes; namespace testPrj { public partial class MainPage : UserControl { public MainPage() { // Required to initialize variables InitializeComponent(); } private void onClick(object sender, System.Windows.RoutedEventArgs e) { Storyboard1.Stop(); sound2_mp3.Stop(); sound1_mp1.Play(); } } } ...................................................................................................

  • HTML Types - Learning Order?

    - by Gabe
    I've decided that today - as soon as this question is answered, in fact - I'm going to dive into learning HTML. But, looking online, I've noticed there are many types: HTML, XHTML, HTML5, and so on. So, which should I start with? In what order should I learn them? And, for that first language, where should I learn at?

    - by kavoir.com
    So I need to encode an array in PHP and store it in plain text in MySQL database, my question is should I use serialize() or json_encode()? What are the advantages and disadvantages of each of them? I think either of them would do in this situation. But which one would you prefer and why? If it is for something other than an array?

  • embedded Italic, bold fonts don't look the same in flex as in Windows...

    - by Mark
    ...unless they're something like "Times New Roman" or some other established font with a fully designed italic and bold, presumably in seperate files. Let me explain what I mean (though why no one has commented on this before I have no idea.) Numerous, numerous fonts do not have a seperate file for italic and bold, and in fact to the best of my knowledge don't even have italic and bold defined as such. But if you install them on windows (for example) and then use them in an app, You can still make use of italic and bold with those fonts. For italic, and oblique angle is just given to it, presumably by Windows, and it looks the same in all Windows apps, and the bold is just given a heavier weight. OK, well here's the problem: if you embed a font like that in a Flex app, as a "SystemFont" the italic and bold will not look the same as they do in Windows. Specifically, the oblique angle is invariably much less than in Windows (i.e the italic slant is much less) and the bold version is not bold enough. I vaguely recall thinking that there was some flex mechanism to assign custom oblique angles for italic (and weight for bold) but now can't recall what it is. Does anyone know the correct established way to do this. The following is actually a seperate (but related) font question (in case anyone is expert in all this.) Its rather a lengthy question and can be skipped, but its something that's plagued me for a long time. I mention above embedding as a "SystemFont", so iow something like this: package fonts { import flash.display.Sprite; public class FLW_Script_I extends Sprite { [Embed(systemFont='FLW Script', fontName='FLW Script', fontStyle='italic', fntWeight='normal', mimeType='application/x-font-truetype')] public var wrFont:Class; } } The other alternative to SystemFont for embedding, is "Source" followed by the name of an actual font file. If you try to embed one of the aformentioned single file fonts as a Source file (as opposed to SystemFont) and specify fontStyle='italic', then the mxmlc compiler will return an error and say there is no italic info in the font file. So up to now I have only been embedding these fonts as "SystemFont". The problem is, flex uses two different font compilers internally for Source embedding and SystemFont embedding. For source font embeds it uses the "Batik" compiler and for SystemFont, the JRE (Java Runtime) font compiler. Well actually the Batik is considered a superior compiler and generally produces better looking fonts. And also if you mix normal fonts compiled with Batik and italic compiled with JRE, sometimes the line spacing is different for the two, and it doesn't look right. So does anyone have an idea how to get mxmlc to do italic and bold for these single file fonts when embedding as "Source". Would there be a way using C++ or whatever to construct an "italic" font file from the SystemFont for such a font in windows.

  • Why is this c# snippet legal?

    - by Sir Psycho
    Silly question, but why does the following line compile? int[] i = new int[] {1,}; As you can see, I haven't entered in the second element and left a comma there. Still compiles even though you would expect it not to.

    This is quite possibly an extremely retarded question, but what is the best way to draw a line over a black and white (binary) image in MATLAB, provided the start and end coordinates are known? Please note, I am not trying to add an annotation line, I would like the line to become part of the image.

    Two questions (questions #2 and #3) did not populate in my survey for respondents. All questions, including these two, was mandatory. The question is visible in the preview and when tested (testing was completed eight times). The browser is internet explorer. The survey link is: https://www.surveymonkey.com/s/3YWNTR5 This survey was used for a graduate school Capstone research project. If I could recover the answers to these questions, I would be grateful. Thank you, Jennifer Granger

  • Enumerating and using wmp visualizers

    - by monoceres
    Hi! I want to use the systems available windows media player visualizers in my app. Apperently visualizers expose an IWMPEffects interface to the world. My question is how do I enumerate and create instances to the available visualizers on my system? Probably it's just a process of getting the cslid of the visualizers and then create the instance with CoCreateInstance. However I have no idea how to get these clsid's! Thanks!

  • Java - Collections.sort() performance

    - by msr
    Hello, Im using Collections.sort() to sort a LinkedList whose elements implements Comparable interface, so they are sorted in a natural order. In the javadoc documentation its said this method uses mergesort algorithm wich has n*log(n) performance. My question is if there is a more efficient algorithm to sort my LinkedList? The size of that list could be very high and sort will be also very frequent. Thanks!

  • Post/Redirect/Get Pattern and Sticky Forms

    - by Scott Christopherson
    I'm using the Post/Redirect/Get pattern on a form of mine. I've never used this approach before and I'm trying to figure something out: Normally, I always just displayed the posted form again when there were validation errors and displayed POST values in the form (sticky form). However with the PRG pattern, the form is displayed after a redirect, so there aren't any POST values. So my question is, how can I implement the PRG pattern and still have sticky forms?

    - by hero
    i am using pcap library to sniff some packets, change their tcp data , and then inject my packet on the network. my question is: if i changed in the tcp data, should i recalculate the length field in the tcp header? should i also change the checksum? i read in a page on how to create raw sockets that if you set the tcp_checksum to 0, the kernel will automatically calculate it and fill it, is this true for windows machines also?

  • Cross-Browser CSS3 Rule

    - by Alexander Corotchi
    I have a stupid question, If I want to add round corner for an element in browsers which support some stuff of CSS3, I have to repeat style several time for each browser, because it is different ? For ex : -moz-border-radius: 12px; /* FF1+ */ -webkit-border-radius: 12px; /* Saf3+, Chrome */ border-radius: 12px; /* Opera 10.5, IE 9 */ It means, that I have to add 3 styles for this radius border, doesn't it ?
