  • Convert Ruby array of tuples into a hash given an array of keys?

    - by Kit Ho
    I have an simple array array = ["apple", "orange", "lemon"] array2 = [["apple", "good taste", "red"], ["orange", "bad taste", "orange"], ["lemon" , "no taste", "yellow"]] how can i convert in to this hash whenever element in array match the first element of each element in array2? hash = {"apple" => ["apple" ,"good taste", "red"], "orange" => ["orange", "bad taste", "orange"], "lemon" => ["lemon" , "no taste", "yellow"] } I am quite new to ruby, and spend a lot to do this manipulation, but no luck, any help ?

  • Redmine on Apache2 with Passenger issue

    - by nkr1pt
    I installed Redmine and run it in Apache2 with the Passenger module. Apache2 boots, Passenger module gets loaded and the Redmine welcome page is shown, however when trying to login or navigate to other parts of the Redmine site, the browser keeps loading and loading and loading forever, although the Redmine production.log indicates redirects and HTTP 200 codes in the header, so everything seems to work correctly according to the log. I tested in various browsers. Does anyone have an idea what could be wrong? I will add apache configuration and some relevant log snippets from both apache and redmine hereafter.

  • Why is HttpClient's GetStringAsync is unbelivable slow?

    - by Jason94
    I have a Windows Phone 8 project where I've taken to use the PCL (Portable Class Library) project too since I'm going to build a Win8 app to. However, while calling my api (in Azure) my HttpClient's GetStringAsync is so slow. I threw in a couple of debugs with datetime and GetStringAsync took like 14 seconds! And sometimes it takes longer. What I'm doing is retrieving simple JSON from my Azure API site. My Android client has no problem with getting that same data in a split second... so is there something I'm missing? The setup is pretty straight forward: HttpClient client = new HttpClient(); client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); client.DefaultRequestHeaders.Add("X-Token", "something"); string responseJSON = await client.GetStringAsync("url"); I've places the debug times right before and after the await there, in between it is 14 seconds! Does someone know why?

  • ASP.Net: IHttpAsyncHandler and AsyncProcessorDelegate

    - by ctrlShiftBryan
    I have implemented an IHttpAsyncHandler. I am making about 5 different AJAX calls from a webpage that has widgets to that handler. One of those widgets takes about 15 seconds to load(because of a large database query) the others should all load in under a second. The handler is responding in a synchronous manner. I am getting very inconsistent results. The ProcessRequest method is using Session and other class level variables. Could that be causing different requests to use the same thread instead each there own? I'm getting this... Request1 --- response 1 sec Request2 --- response 14 sec Request3 --- response 14.5 sec Request4 --- response 15 sec Request5 --- response 15.5 sec but I'm looking for something more like this... Request1 --- response 1 sec Request2 --- response 14 sec Request3 --- response 1.5 sec Request4 --- response 2 sec Request5 --- response 1.5 sec Without posting too much code my implementation of the IHttpAsyncHandler methods are pretty standard. private AsyncProcessorDelegate _Delegate; protected delegate void AsyncProcessorDelegate(HttpContext context); IAsyncResult IHttpAsyncHandler.BeginProcessRequest(HttpContext context, AsyncCallback cb, object extraData) { _Delegate = new AsyncProcessorDelegate(ProcessRequest); return _Delegate.BeginInvoke(context, cb, extraData); } void IHttpAsyncHandler.EndProcessRequest(IAsyncResult result) { _Delegate.EndInvoke(result); } Putting a debug break point in my IHttpAsyncHandler.BeginProcessRequest method I can see that the method isn't being fired until the last Process is complete. Also my machine.config has this entry... processModel autoConfig="true" with no other properties set. What else do I need to check for?

  • C# - update variable based upon results from backgroundworker

    - by Bruce
    I've got a C# program that talks to an instrument (spectrum analyzer) over a network. I need to be able to change a large number of parameters in the instrument and read them back into my program. I want to use backgroundworker to do the actual talking to the instrument so that UI performance doesn't suffer. The way this works is - 1) send command to the instrument with new parameter value, 2) read parameter back from the instrument so I can see what actually happened (for example, I try to set the center frequency above the max that the instrument will handle and it tells me what it will actually handle), and 3) update a program variable with the actual value received from the instrument. Because there are quite a few parameters to be updated I'd like to use a generic routine. The part I can't seem to get my brain around is updating the variable in my code with what comes back from the instrument via backgroundworker. If I used a separate RunWorkerCompleted event for each parameter I could hardwire the update directly to the variable. I'd like to come up with a way of using a single routine that's capable of updating any of the variables. All I can come up with is passing a reference number (different for each parameter) and using a switch statement in the RunWorkerCompleted handler to direct the result. There has to be a better way. Thanks for your help.

  • Calling end invoke on an asynchronous call when an exception has fired in WCF.

    - by james.ingham
    Hey, I currently have an asynchronous call with a callback, which fires this method on completion: private void TestConnectionToServerCallback(IAsyncResult iar) { bool result; try { result = testConnectionDelegate.EndInvoke(iar); Console.WriteLine("Connection made!"); } catch (EndpointNotFoundException e) { Console.WriteLine("Server Timeout. Are you connected?"); result = false; } ... } With the EndpointNotFoundException firing when the server is down or no connection can be made. My question is this, if I want to recall the testConnectionDelegate with some kind of re-try button, must I first call testConnectionDelegate.EndInvoke where the exception is caught? When I do call end invoke in the catch, I get another exception on result = testConnectionDelegate.EndInvoke(iar); whenever I call this method for the second time. This is "CommunicationObjectFaultedException". I'm assuming this is because I didn't end it properly, which is what I think I have to do. Any help would be appreciated. Thanks - James

  • What is stopping data flow with .NET 3.5 asynchronous System.Net.Sockets.Socket?

    - by TonyG
    I have a .NET 3.5 client/server socket interface using the asynchronous methods. The client connects to the server and the connection should remain open until the app terminates. The protocol consists of the following pattern: send stx receive ack send data1 receive ack send data2 (repeat 5-6 while more data) receive ack send etx So a single transaction with two datablocks as above would consist of 4 sends from the client. After sending etx the client simply waits for more data to send out, then begins the next transmission with stx. I do not want to break the connection between individual exchanges or after each stx/data/etx payload. Right now, after connection, the client can send the first stx, and get a single ack, but I can't put more data onto the wire after that. Neither side disconnects, the socket is still intact. The client code is seriously abbreviated as follows - I'm following the pattern commonly available in online code samples. private void SendReceive(string data) { // ... SocketAsyncEventArgs completeArgs; completeArgs.Completed += new EventHandler<SocketAsyncEventArgs>(OnSend); clientSocket.SendAsync(completeArgs); // two AutoResetEvents, one for send, one for receive if ( !AutoResetEvent.WaitAll(autoSendReceiveEvents , -1) ) Log("failed"); else Log("success"); // ... } private void OnSend( object sender , SocketAsyncEventArgs e ) { // ... Socket s = e.UserToken as Socket; byte[] receiveBuffer = new byte[ 4096 ]; e.SetBuffer(receiveBuffer , 0 , receiveBuffer.Length); e.Completed += new EventHandler<SocketAsyncEventArgs>(OnReceive); s.ReceiveAsync(e); // ... } private void OnReceive( object sender , SocketAsyncEventArgs e ) {} // ... if ( e.BytesTransferred > 0 ) { Int32 bytesTransferred = e.BytesTransferred; String received = Encoding.ASCII.GetString(e.Buffer , e.Offset , bytesTransferred); dataReceived += received; } autoSendReceiveEvents[ SendOperation ].Set(); // could be moved elsewhere autoSendReceiveEvents[ ReceiveOperation ].Set(); // releases mutexes } The code on the server is very similar except that it receives first and then sends a response - the server is not doing anything (that I can tell) to modify the connection after it sends a response. The problem is that the second time I hit SendReceive in the client, the connection is already in a weird state. Do I need to do something in the client to preserve the SocketAsyncEventArgs, and re-use the same object for the lifetime of the socket/connection? I'm not sure which eventargs object should hang around during the life of the connection or a given exchange. Do I need to do something, or Not do something in the server to ensure it continues to Receive data? The server setup and response processing looks like this: void Start() { // ... listenSocket.Bind(...); listenSocket.Listen(0); StartAccept(null); // note accept as soon as we start.

  • Cannot use await in Portable Class Library for Win 8 and Win Phone 8

    - by Harry Len
    I'm attempting to create a Portable Class Library in Visual Studio 2012 to be used for a Windows 8 Store app and a Windows Phone 8 app. I'm getting the following error: 'await' requires that the type 'Windows.Foundation.IAsyncOperation' have a suitable GetAwaiter method. Are you missing a using directive for 'System'? At this line of code: StorageFolder guidesInstallFolder = await Package.Current.InstalledLocation.GetFolderAsync(guidesFolder); My Portable Class Library is targeted at .NET Framework 4.5, Windows Phone 8 and .NET for Windows Store apps. I don't get this error for this line of code in a pure Windows Phone 8 project, and I don't get it in a Windows Store app either so I don't understand why it won't work in my PCL. The GetAwaiter is an extension method in the class WindowsRuntimeSystemExtensions which is in System.Runtime.WindowsRuntime.dll. Using the Object Browser I can see this dll is available in the .NET for Windows Store apps component set and in the Windows Phone 8 component set but not in the .NET Portable Subset. I just don't understand why it wouldn't be in the Portable Subset if it's available in both my targeted platforms.

  • How to notify client about updated UpdatePanel content on server side

    - by csh1981
    I have a problem with UpdatePanel.Update() which works initially but then stops. I have tumbled with this problem for some time and some background is needed so please read ahead. I have an ASP.net application in which I have a subpage that display computed information in graphs. Each graph is embedded in an UpdatePanel. The graph is a user control that uses the standard asp:Chart for display. My task is to enable this page with AJAX capabilities so the page is responsive during postbacks. When I access this page from another page, during the initial page rendering, I use a wait dialog for each graph and a pageload event on the client side. In the client event, a hidden button is clicked which a server event handles (the hidden button is inside an UpdatePanel so the postback is asynchronous). Each graph is computed and the UpdatePanels are in turn updated with the Chart content. This is done using UpdatePanel.Update. And it is successful. However, I also have some RadioButtons on the page. These are dynamically created. The purpose of them is to switch graph type --- to show the same data in a different way. Same type of time consuming computation is needed in order to do so. I subscribe on each RadioButton's OnCheckedChanged event and the postback is asynchronous since the radiobuttons are inside an UpdatePanel. In the server event handler I determine the type of graph and use this as an input to the Chart control. I then remove the old Chart control from my Panel and adds new Chart and then I call UpdatePanel.Update(). But with no success. Nothing happens, no errors, nothing. Why is this?? I think this is strange because if I compute every Chart data in the initial rendering instead of using the "Wait dialog"-solution described earlier then I can select graph types successfully and all subsequent AJAX requests work as intended. Also, the same code (computing the chart, removal, and adding the Chart control to Panel and UpdatePanel.Update()) is hit during the initial rendering of the page, and it works only the first time. Here is the method that computes the graph and adds it to the panel and update the UpdatePanel: public void UpdateGraph(GraphType type, GraphMapper mapper) { //Panel is the content of UpdatePanelGraph's Panel.Controls.Clear(); chart = new Chart(type, mapper); //Computation happens inside here panel.Controls.Add(chart); //UpdatePanelGraph is in UpdateMode Conditional and has //ChildrenAsTriggers set to false UpdatePanelGraph.Update(); } I really need a way for these radiobuttons to work, possible using some clientside JavaScript or another way of handling things on the server side. I have thought about using a JavaScript postback call on the UpdatePanel instead of the UpdatePanel.Update(). However, the issue I have here is how to notify the client side when the server side is finished with computing the graph? An plausible explanation of the strange behavior is also much appreciated. Any help appreciated, thanks

  • ASP.NET MVC 2 Cancel Asynchronous Action

    - by Sean Carpenter
    The MSDN documentation for using an asynchronous controller mentions choosing an asynchronous controller when you want to provide a way for users to cancel requests. I couldn't find any documentation related to actually allowing users to cancel asynchronous requests, however. Is there a way to indicate to ASP.Net and/or the MVC framework that a request should be canceled?

  • Render asp.net repeater as-and-when chunks of html is ready (streaming)

    - by sash
    The problem is to render huge reports. Basically we have lots of data that get rendered in html reports (mostly using repeater or gridview). As it so happens, the data started out small and now we have tons of it. There are lots of such reports already built so total rewrite is not an option. Heck, the business is not even letting us page the data. Now server memory is shooting up each time we try to render some reports. So the question is - is there some way we can bind data to repeater and have it stream html to browser as and when chunks are ready? That way we hope to not bring all that data into app server at once. I'm thinking we'll use a datareader or something to get parts of data and render it to browser. Any pointers, links, ideas?

  • What is a simple way to add a timer to a method

    - by John
    The following is in C#. I'm trying to do something very simple (I think). I have a method that loads an XML document XDocument doc = XDocument.Load(uri); , but I don't want to tie up pc resources if there are issues (connectivity, document size, etc.). So I'd like to be able to add a timeout variable that will cut the method off after a given number of seconds. I'm a newbie when it comes to asynchronous programming and find it confusing that there are so many examples written so many different ways . . . and none of them appear simple. I'd like a simple solution, if possible. Here's my thoughts so far on possible solution paths: 1) A method that wraps the existing load public XDocument LoadXDocument(string uri, int timeout){ //code } 2) A wrapper, but as an extension method XDocument doc = XDocument.LoadWithTimeout(string uri, int timeout); 3) A generic extension method. Object obj = SomeStaticClass.LoadWithTimeout(??? method, int timeout); 3), on its face seems really nice, because it would mean being able to generically add timeouts to many different method calls and not specifically tied to one type of object, but I suspect that it is either i)impossible or ii) very difficult. Please assist. Thanks.

  • What's wrong with consuming ConfiguredTaskAwaitable from PortableClassLibrary's class under Debugger from MSTest Runner or Console App?

    - by Stas Shusha
    *Its only Debug-time error, but a very weird one. Problem: While running with Debugger attached and calling a method, exposed in separate Portable library, returning ConfiguredTaskAwaitable, we get InvalidProgramException. Repro: Having 2 projects: PortableClassLibrary (supporting .Net 4.5; Windows Store; Windows Phone 8) with 1 class: public class Weird { public static ConfiguredTaskAwaitable GetConfiguredTaskAwaitable() { return new ConfiguredTaskAwaitable(); } } ConsoleApplication with code: static void Main(string[] args) { Weird.GetConfiguredTaskAwaitable(); } Notes: replacing ConfiguredTaskAwaitable with ConfiguredTaskAwaitable<T> (a generic version) fixes this strange issue consuming this method form WP8 or Win8 app under Debugger works fine. Currently it causes problems cause I cant run my Unit Tests under Debugger. I'm forced to change my "ObjectUnderTest" implementation to return generic ConfiguredTaskAwaitable<T>, which is fine for the real project, but still is only a workaround. The Question is: does anybody knows the reason of this error? It definitely related to Portable Class Library magic.

  • Can I use a single instance of a delegate to start multiple Asynchronous Requests?

    - by RobV
    Just wondered if someone could clarify the use of BeginInvoke on an instance of some delegate when you want to make multiple asynchronous calls since the MSDN documentation doesn't really cover/mention this at all. What I want to do is something like the following: MyDelegate d = new MyDelegate(this.TargetMethod); List<IAsyncResult> results = new List<IAsyncResult>(); //Start multiple asynchronous calls for (int i = 0; i < 4; i++) { results.Add(d.BeginInvoke(someParams, null, null)); } //Wait for all my calls to finish WaitHandle.WaitAll(results.Select(r => r.AsyncWaitHandle).ToArray()); //Process the Results The question is can I do this with one instance of the delegate or do I need an instance of the delegate for each individual call? Given that EndInvoke() takes an IAsyncResult as a parameter I would assume that the former is correct but I can't see anything in the documentation to indicate either way.

  • If I register a domain name using a service like A Small Orange, how can I know they are registering

    - by Sergio Tapia
    I have a great name for a website and it's available, but I don't really know how to register a domain name using a barebones website; that's why I want to use A Small Orange-like service. My question is, is it standard procedure to register the name on YOUR(the costumers) behalf, or do companies set it up on their name so they can profit from hits if in the future you stop paying for the hosting?

    I'm validating the installation of a program that consists of a few separate modules. They are not co-dependent.

  • How could I change the colour of the menu font in Lubuntu?

    - by cipricus
    I use Lubuntu 12.04 and I have become obsessed with the looks of it! There is a type of themes that I especially want to use (flat, light), all related to the Elegant brit theme. On my desktop it looks like: As I want to replace the dominating orange with blue, I would prefer even more the theme Elegant Brit re-Revisited The problem is that both of them have a problem with my system tray, a white background appears: A theme that is almost identical to the orange one, but has no problem with the system tray is called Elegant Blackle. I have tried to use this one and replaced the gtk2 folder in its main folder with the gtk2 folder from Elegant Brit re-Revisited. The result is an improvement for me, as I have eliminated a part of the orange stuff with a decent blue :). The orange now appears only with the gtk3 apps, which is rather amusing. Migrating also the gtk3 folder from the blue to the orange theme would bring the sys tray problem too: it is something related to that gtk3 folder. But this is another matter. Now I have something very close to what I want. But I especially would like to have a feature that was present in the Elegant Blackle theme and now is gone as its gtk2 folder was replaced by that of the blue theme: the black font of the menus, instead of the blueish ones. Could anyone instruct me what is to be changed in the gtk2 folder of the Elegant Brit re-Revisited theme so as to make the menus look like this (like they do in Elegant Blackle with its original gtk2 folder): and not like this? : (on my display this blue is more whitish). An alternative and ideal solution would be knowing how to edit the Elegant Brit re-Revisited theme so as to remove the systray problem or, maybe easier, to edit the orange colour of Elegant Blackle theme to as to be completely replaced by the blue of the other one.

  • Loading Youtube Iframe API with RequireJS

    - by davidgnin
    I'm trying to use the Youtube Iframe API inside a module definded with Require JS. As this API is loaded async and calls a function once is loaded, I used a requireJS plugin called "async", that worked before with google maps api. However, this time something isn't working. My module starts this way: define(['text!fmwk/widgets/video/video.html','fmwk/utils/browser','async!http://www.youtube.com/iframe_api'], function (videoTpl,root) { ... }); and chrome console fires this error: Uncaught Error: Load timeout for modules: async!http://www.youtube.com/iframe_api_unnormalized3,async!http://www.youtube.com/iframe_api http://requirejs.org/docs/errors.html#timeout If I don't use async plugin the object YT or its functions are undefinded, and the same happens if I download the API code. The API is loaded sometimes if I put an script tag in the head tag of the html file. All this is expected, but I don't understand because async plugin fails. Thank you for your attention and help :)
