  • Import part with specific meta data using MEF Preview 5

    - by Riri
    I have a export defined as as follows in MEF preview 5 [ExportMetadata("Application", "CheckFolderApplication")] [Export(typeof(ExtendedArtifactBase))] public class CheckFolderArtifact2 : ExtendedArtifactBase { ... Then I only want those imports with the "Application" "CheckFolderApplication" metadata. To currenly do that I read all the imports and then filter the result. [Import(typeof(ExtendedApplicationBase))] private ExportCollection<IApplication> _applications { get; set; } public IApplication GetApplication(string applicationName) { return _applications.Single(a => a.GetExportedObject().Name == applicationName).GetExportedObject(); } This feels really inefficient. What if I have thousands of plug-ins - do I have to read them all via MEF to just get one with the right metadata? If so how do you cache the result?

  • ServerVariables and POST Data

    - by tyndall
    I've got a piece of tracking code which is capturing REMOTE_HOST, SERVER, REQUEST_METHOD, SCRIPT_NAME and QUERY_STRING. It grabs these from ServerVariables and sticks them in a database by user and IP. What is the best way to pick up the exact contents of what was posted back to a URL in ASP.NET? Is there an HTTP_POST? I'd rather not grab something and then have to parse it.

  • C# Retrieving Data From XML File

    - by Christopher MacKinnon
    I seem to be having a problem with retrieving XML values with C#, which I know it is due to my very limited knowledge of C# and .XML. I was given the following XML file <PowerBuilderRunTimes> <PowerBuilderRunTime> <Version>12</Version> <Files> <File>EasySoap110.dll</File> <File>exPat110.dll</File> <File>pbacc110.dll</File> </File> </PowerBuilderRunTime> </PowerBuilderRunTimes> I am to process the XML file and make sure that each of the files in the exist in the folder (that's the easy part). It's the processing of the XML file that I have having a hard time with. Here is what I have done thus far: var runtimeXml = File.ReadAllText(string.Format("{0}\\{1}", configPath, Resource.PBRuntimes)); var doc = XDocument.Parse(runtimeXml); var topElement = doc.Element("PowerBuilderRunTimes"); var elements = topElement.Elements("PowerBuilderRunTime"); foreach (XElement section in elements) { //pbVersion is grabbed earlier. It is the version of PowerBuilder if( section.Element("Version").Value.Equals(string.Format("{0}", pbVersion ) ) ) { var files = section.Elements("Files"); var fileList = new List<string>(); foreach (XElement area in files) { fileList.Add(area.Element("File").Value); } } } My issue is that the String List is only ever populated with one value, "EasySoap110.dll", and everything else is ignored. Can someone please help me, as I am at a loss.

  • Subset and lagging list data structure R

    - by user1234440
    I have a list that is indexed like the following: >list.stuff [[1]] [[1]]$vector ... [[1]]$matrix .... [[1]]$vector [[2]] null [[3]] [[3]]$vector ... [[3]]$matrix .... [[3]]$vector . . . Each segment in the list is indexed according to another vector of indexes: >index.list 1, 3, 5, 10, 15 In list.stuff, only at each of the indexes 1,3,5,10,15 will there be 2 vectors and one matrix; everything else will be null like [[2]]. What I want to do is to lag like the lag.xts function so that whatever is stored in [[1]] will be pushed to [[3]] and the last one drops off. This also requires subsetting the list, if its possible. I was wondering if there exists some functions that handle list manipulation. My thinking is that for xts, a time series can be extracted based on an index you supply: xts.object[index,] #returns the rows 1,3,5,10,15 From here I can lag it with: lag.xts(xts.object[index,]) Any help would be appreciated thanks: EDIT: Here is a reproducible example: list.stuff<-list() vec<-c(1,2,3,4,5,6,7,8,9) vec2<-c(1,2,3,4,5,6,7,8,9) mat<-matrix(c(1,2,3,4,5,6,7,8),4,2) list.vec.mat<-list(vec=vec,mat=mat,vec2=vec2) ind<-c(2,4,6,8,10) for(i in ind){ list.stuff[[i]]<-list.vec.mat }

  • flex data provider not working if XML has single node value or less

    - by Rees
    hello, i get this error when i retrieve an XML that only has 1 node (no repeating nodes) and i try to store in an ArrayCollection. -When I have MORE than 1 "name" nodes...i do NOT get an error. My test show that XMLListCollection does NOT work either. TypeError: Error #1034: Type Coercion failed: cannot convert "XXXXXX" to mx.collections.ArrayCollection. this error occurs as the line of code: myList= e.result.list.name; Why can't ArrayCollection work with a single node? I'm using this ArrayCollection as a dataprovider for a Component -is there an alternative I can use that will take BOTH single and repeating nodes as well as work as a dataprovider? Thanks in advance! code: [Bindable] private var myList:ArrayCollection= new ArrayCollection(); private function getList(e:Event):void{ var getStudyLoungesService:HTTPService = new HTTPService(); getStuffService.url = "website.com/asdf.php"; getStuffService.addEventListener(ResultEvent.RESULT, onGetList); getStuffService.send(); } private function onGetList(e:ResultEvent):void{ myList= e.result.list.name; }

  • Can I use WCF NET.TCP Protocol from Silverlight 4 for a public website ?

    - by pixel3cs
    Does anyone know if the new NET.TCP feature of Silverlight 4 can be used for public websites ? From what I know, in the Silverlight 4 Beta they announced that WCF NET.TCP can only be used for intranet applications. The reason I am asking this is because I want to recode my Silverlight multiplayer chess game (build with SL 3 Sockets support) based on the new SL 4 WCF TCP communication protocol. My Socket implementation is build from scratch and have big issues with thread safe and few unsolvable bugs from my side. I am sure that SL 4 team did a great job and they simplified all hard part for me, letting us, developers, concentrate more on the game code instead on underlying communication layers.

  • choose the best class if 2 class have same P (c|d), naive bayes

    - by ryandi
    Hello I have some question about naive bayes classifier . In my project I have to classify a text into a class from 4 available class. In naive bayes we have formula like cmap=argmax.P(d|c).P(c) I have standarize the amount of training document of each class, so I got a same P(c) value for each class (0.25). Here's my question: What if a testing document token doesn't have any token which belong to any of those 4 class(in document training)? Resulted to all of the class have same value of P(d|c).P(c). Which class should i pick? What if the token exist, and 2 class or more have same value of P(d|c).P(c) what should I do? Thank you..

  • PostgeSQL: Arrays Data Type with PHP

    - by ArchJ
    I'm working on PostgeSQL with PHP and I know that PosrgeSQL allow columns of a table to be defined as arrays. So let's say I have a table like this: CREATE TABLE sal_emp ( a text ARRAY, b text ARRAY, c text ARRAY, ); These are my arrays: $a = array(aa,bb,cc); $b = array(dd,dd,aa); $c = array(bb,ff,ee); and I want to insert them into respective column each like this: a | b | c -----------+------------+------------ {aa,bb,cc} | {dd,dd,aa} | {bb,ff,ee} Can I insert it this way? $a = implode(',', $a); $b = implode(',', $b); $c = implode(',', $c); $a = array('a' => $a, 'b' => $b, 'c' => $c); pg_insert($dbconn, 'table', $a); Or is there a better way to achieve the same result?

  • In-order tree traversal

    - by Chris S
    I have the following text from an academic course I took a while ago about in-order traversal (they also call it pancaking) of a binary tree (not BST): In-order tree traversal Draw a line around the outside of the tree. Start to the left of the root, and go around the outside of the tree, to end up to the right of the root. Stay as close to the tree as possible, but do not cross the tree. (Think of the tree — its branches and nodes — as a solid barrier.) The order of the nodes is the order in which this line passes underneath them. If you are unsure as to when you go “underneath” a node, remember that a node “to the left” always comes first. Here's the example used (slightly different tree from below) However when I do a search on google, I get a conflicting definition. For example the wikipedia example: Inorder traversal sequence: A, B, C, D, E, F, G, H, I (leftchild,rootnode,right node) But according to (my understanding of) definition #1, this should be A, B, D, C, E, F, G, I, H Can anyone clarify which definition is correct? They might be both describing different traversal methods, but happen to be using the same name. I'm having trouble believing the peer-reviewed academic text is wrong, but can't be certain.
