  • Javascript - find swfobject on included page and call javascript function

    - by Rob
    I’m using the following script on my website to play an mp3 in flash. To instantiate the flash object I use the swfobject framework in a javascript function. When the function is called the player is created and added to the page. The rest of the website is in php and the page calling this script is being included with the php include function. All the other used scripts are in the php 'master'-page var playerMp3 = new SWFObject("scripts/player.swf","myplayer1","0","0","0"); playerMp3.addVariable("file","track.mp3"); playerMp3.addVariable("icons","false"); playerMp3.write("player1"); var player1 = document.getElementById("myplayer1"); var status1 = $("#status1"); $("#play1").click(function(){ player1.sendEvent("play","true"); $("#status1").fadeIn(400); player4.sendEvent("stop","false"); $("#status4").fadeOut(400); player3.sendEvent("stop","false"); $("#status3").fadeOut(400); player2.sendEvent("stop","false"); $("#status2").fadeOut(400); }); $("#stop1").click(function(){ player1.sendEvent("stop","false"); $("#status1").fadeOut(400); }); $(".closeOver").click(function(){ player1.sendEvent("stop","false"); $("#status1").fadeOut(400); }); $(".accordionButton2").click(function(){ player1.sendEvent("stop","false"); $("#status1").fadeOut(400); }); $(".accordionButton3").click(function(){ player1.sendEvent("stop","false"); $("#status1").fadeOut(400); }); $(".turnOffMusic").click(function(){ player1.sendEvent("stop","false"); $("#status1").fadeOut(400); }); }); I have a play-button with the id ‘#play1’ and a stop-button with the id ‘#stop1’ on my page. A div on the same page has the id ‘#status1’ and a little image of a speaker is in the div. When you push the playbutton, the div with the speaker is fading in and when you push the stopbutton, the div with the speaker is fading out, very simple. And it works as I want it to do. But the problem is, when a song is finished, the speaker doesn’t fade out. Is there a simple solution for this? I already tried using the swfobject framework to get the flash player from the page and call the ‘IsPlaying’ on it, but I’m getting the error that ‘swfobject’ can’t be found. All I need is a little push in the right direction or an example showing me how I can correctly get the currently playing audio player (in flash), check if it’s playing and if finished, call a javascript function to led the speaker-image fade-out again. Hope someone here can help me

  • How can I best share Ant targets between projects?

    - by Rob Hruska
    Is there a well-established way to share Ant targets between projects? I have a solution currently, but it's a bit inelegant. Here's what I'm doing so far. I've got a file called ivy-tasks.xml hosted on a server on our network. This file contains, among other targets, boilerplate tasks for managing project dependencies with Ivy. For example: <project name="ant-ivy-tasks" default="init-ivy" xmlns:ivy="antlib:org.apache.ivy.ant"> ... <target name="ivy-download" unless="skip.ivy.download"> <mkdir dir="${ivy.jar.dir}"/> <echo message="Installing ivy..."/> <get src="http://repo1.maven.org/maven2/org/apache/ivy/ivy/${ivy.install.version}/ivy-${ivy.install.version}.jar" dest="${ivy.jar.file}" usetimestamp="true"/> </target> <target name="ivy-init" depends="ivy-download" description="-> Defines ivy tasks and loads global settings"> <path id="ivy.lib.path"> <fileset dir="${ivy.jar.dir}" includes="*.jar"/> </path> <taskdef resource="org/apache/ivy/ant/antlib.xml" uri="antlib:org.apache.ivy.ant" classpathref="ivy.lib.path"/> <ivy:settings url="http://myserver/ivy/settings/ivysettings-user.xml"/> </target> ... </project> The reason this file is hosted is because I don't want to: Check the file into every project that needs it - this will result in duplication, making maintaining the targets harder. Have my build.xml depend on checking out a project from source control - this will make the build have more XML at the top-level just to access the file. What I do with this file in my projects' build.xmls is along the lines of: <property name="download.dir" location="download"/> <mkdir dir="${download.dir}"/> <echo message="Downloading import files to ${download.dir}"/> <get src="http://myserver/ivy/ivy-tasks.xml" dest="${download.dir}/ivy-tasks.xml" usetimestamp="true"/> <import file="${download.dir}/ivy-tasks.xml"/> The "dirty" part about this is that I have to do the above steps outside of a target, because the import task must be at the top-level. Plus, I still have to include this XML in all of the build.xml files that need it (i.e. there's still some amount of duplication). On top of that, there might be additional situations where I might have common (non-Ivy) tasks that I'd like imported. If I were to provide these tasks using Ivy's dependency management I'd still have problems, since by the time I'd have resolved the dependencies I would have to be inside of a target in my build.xml, and unable to import (due to the constraint mentioned above). Is there a better solution for what I'm trying to accomplish?

  • Form Elements in ASP.NET Master Pages and Content Pages

    - by Rob Cooper
    OK, another road bump in my current project. I have never had form elements in both my master and content pages, I tend to have all the forms in the content where relevant. In the current project however, we have a page where they want both. A login form at the top right, and a questions form in the content. Having tried to get this in, I have run in to the issue of ASP.NET moaning about the need for a single form element in a master page. TBH, I really dont get why this is a requirement on ASP.NET's part, but hey ho. Does anyone know if/how I can get the master and content pages to contain form elements that work independantly? If not, can you offer advice on how to proceed to get the desired look/functionality?

  • OCR: How to improve accuracy - existing libraries for removing non-text 'furniture', shapes, etc to

    - by Rob
    I want to remove rectangles etc that enclose text in a screenshot image, so that I can perform optical character recognition to get accurate text from the screenshot. Background: I doing this to extract data from a legacy application for use with other applications. This is the only way to get at this data as associated files are in a closed, proprietary, binary format. I will be using AutoItScript to drive the application to show data in its UI, then I will screenshot this and feed this to tesseract. I've already had some success in automating the UI, and have been able to use tesseract to get plain ascii text out of the bitmap. There are several AutoItScripr forum articles discussing its use with tesseract/OCR but not specifically for my question. http://www.autoitscript.com/forum/index.php?s=6c32c3ece12756e635a619cdf175eff9&showforum=2 What I need to do There are thin, 1-pixel wide rectangles that closely enclose some text, when fed to tesseract, it sees them as I for example for a verticle line of the rectangle. Any thoughts on how to remove the rectangles, or best practices? I'm asking if there is a generic command line based toolset to overwrite rectangles, for example, in .png files. I could then pass the .png through this, then pass it to tesseract. Details on the tesseract release/setup I've used are as follows: Go here: http://code.google.com/p/tesseract-ocr/downloads/list - For the basic english generic character set to get Tesseract up and running and recognising your bitmapped text into ascii text, use tesseract-2.00.eng.tar.gz (current version at time of writing is: "English language data for Tesseract (2.00 and up) Jul 2007 989 KB 84845") Related questions I have already looked at on Stack Overflow http://stackoverflow.com/questions/1335581/how-to-give-best-chance-of-success-to-an-ocr-software http://stackoverflow.com/questions/2296568/analysis-and-transformation-of-the-image-on-the-basis-of-this-analysis-for-better http://stackoverflow.com/questions/2268028/reading-characters-off-of-the-screen In these, my question is not completely answered or a commercial solution is being sold. I do not want to consider a commercial solution at this stage.

  • How can I define a clojure type that implements the servlet interface?

    - by Rob Lachlan
    I'm attempting to use deftype (from the bleeding-edge clojure 1.2 branch) to create a java class that implements the java Servlet interface. I would expect the code below to compile (even though it's not very useful). (ns foo [:import [javax.servlet Servlet ServletRequest ServletResponse]]) (deftype servlet [] javax.servlet.Servlet (service [this #^javax.servlet.ServletRequest request #^javax.servlet.ServletResponse response] nil)) But it doesn't compile. The compiler produces the message: Mismatched return type: service, expected: void, had: java.lang.Object [Thrown class java.lang.IllegalArgumentException] Which doesn't make sense to me, because I'm returning nil. So the fact that the return type of the method is void shouldn't be a problem. For instance, for the java.util.Set interface: (deftype bar [#^Number n] java.util.Set (clear [this] nil)) compiles without issue. So what am I doing wrong with the Servlet interface? To be clear: I know that the typical case is to subclass one of the servlet abstract classes rather than implement this interface directly, but it should still be possible to do this. Stack Trace: The stack trace for the (deftype servlet... is: Mismatched return type: service, expected: void, had: java.lang.Object [Thrown class java.lang.IllegalArgumentException] Restarts: 0: [ABORT] Return to SLIME's top level.

  • Translate query to NHibernate

    - by Rob Walker
    I am trying to learn NHibernate, and am having difficulty translating a SQL query into one using the criteria API. The data model has tables: Part (Id, Name, ...), Order (Id, PartId, Qty), Shipment (Id, PartId, Qty) For all the parts I want to find the total quantity ordered and the total quantity shipped. In SQL I have: select shipment.part_id, sum(shipment.quantity), sum(order.quantity) from shipment cross join order on order.part_id = shipment.part_id group by shipment.part_id Alternatively: select id, (select sum(quantity) from shipment where part_id = part.id), (select sum(quantity) from order where part_id = part.id) from part But the latter query takes over twice as long to execute. Any suggestions on how to create these queries in (fluent) NHibernate? I have all the tables mapped and loading/saving/etc the entities works fine.

  • Hibernate Schema Validation Fails on Oracle Table Synonyms

    - by Rob
    I'm developing a Java web application that uses Hibernate (annotations-based) for persisting entities to an Oracle 11g database. The DBA created synonyms for the tables and requested that I use these synonyms instead of the physical tables. (Eg: Table "Foo" has synonym "S_Foo") If I have "hibernate.hbm2ddl.auto=validate" enabled, then the application fails on startup with "Missing Table: S_Foo". If I turn off the validation, then the app starts up fine and works properly. My guess is that Hibernate only checks against physical tables and not synonyms when validating that a table exists. Is there any way to enable Hibernate schema validation with synonyms? Can I specify both a physical table and a synonym in the annotation? I prefer having that extra safety check that the table structure is correct when the application starts up.

  • How is WPF Data Binding using Object Data Source in Visual Studio 2010 done?

    - by Rob Perkins
    This is probably mostly a question about how to use the VS 2010 IDE tools in a way the Microsofties didn't specifically intend. But since this is something I immediately tried without success. I have defined a .NET 4.0 WPF Application project with a simple class that looks like this: Public Class Class1 Public Property One As String = "OneString" Public Property Two As String = "TwoString" End Class I then defined it as an "Object Data Source" in VS2010, using the IDE's "Add New Data Source..." feature. This exposes the class members in a GUI element in the IDE as given in this image: Dragging "Class1" from that tool to the surface of "Window1.xaml" in a default "WPF Application" results in the design view looking like this: And generated XAML like this: <Window x:Class="Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="133" Width="170" xmlns:my="clr-namespace:WpfApplication1" mc:Ignorable="d" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" > <Window.Resources> <CollectionViewSource x:Key="Class1ViewSource" d:DesignSource="{d:DesignInstance my:Class1, CreateList=True}" /> </Window.Resources> <Grid DataContext="{StaticResource Class1ViewSource}" HorizontalAlignment="Left" Name="Grid1" VerticalAlignment="Top"> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto" /> <ColumnDefinition Width="Auto" /> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition Height="Auto" /> <RowDefinition Height="Auto" /> </Grid.RowDefinitions> <Label Content="One:" Grid.Column="0" Grid.Row="0" HorizontalAlignment="Left" Margin="3" VerticalAlignment="Center" /> <TextBlock Grid.Column="1" Grid.Row="0" Height="23" HorizontalAlignment="Left" Margin="3" Name="OneTextBlock" Text="{Binding Path=One}" VerticalAlignment="Center" /> <Label Content="Two:" Grid.Column="0" Grid.Row="1" HorizontalAlignment="Left" Margin="3" VerticalAlignment="Center" /> <TextBlock Grid.Column="1" Grid.Row="1" Height="23" HorizontalAlignment="Left" Margin="3" Name="TwoTextBlock" Text="{Binding Path=Two}" VerticalAlignment="Center" /> </Grid> Note the data bindings Text="{Binding Path=One}" and Text="{Binding Path=Two}" in the TextBlock elements. Code-behind for Window1.xaml has this in Window_Loaded: Class Window1 Private m_c1 As New Class1 Private Sub Window1_Loaded(ByVal sender As Object, ByVal e As System.Windows.RoutedEventArgs) Handles Me.Loaded Dim Class1ViewSource As System.Windows.Data.CollectionViewSource = CType(Me.FindResource("Class1ViewSource"), System.Windows.Data.CollectionViewSource) 'Load data by setting the CollectionViewSource.Source property: 'Class1ViewSource.Source = [generic data source] Me.DataContext = m_c1 End Sub End Class Running the application produces this output: The expected result was that "OneString" would appear next to "One" and "TwoString" next to "Two" in the running window. The question is: Why didn't this work? What will work instead? If I put bindings in a DataTemplate, it works. Blend, with its sample data stuff, implied that this should work, but it doesn't. I know I'm missing something pretty fundamental here; what is it?

  • Unresolved Host Exception Android

    - by Rob Stevenson-Leggett
    I'm trying to call a RESTful web service from an Android application using the following method: HttpHost target = new HttpHost("http://" + ServiceWrapper.SERVER_HOST,ServiceWrapper.SERVER_PORT); HttpGet get = new HttpGet("/list"); String result=null; HttpEntity entity = null; HttpClient client = new DefaultHttpClient(); try { HttpResponse response=client.execute(target, get); entity = response.getEntity(); result = EntityUtils.toString(entity); } catch (Exception e) { e.printStackTrace(); } finally { if (entity!=null) try { entity.consumeContent(); } catch (IOException e) {} } return result; I can browse to address and see the xml results using the Android Emulator browser and from my machine. I have given my app the INTERNET permission. I'm developing with eclipse. I've seen it mentioned that I might need to configure a proxy but since the web service i'm calling is on port 80 this shouldn't matter should it? I can call the method with the browser. Any ideas?

  • Large Django application layout

    - by Rob Golding
    I am in a team developing a web-based university portal, which will be based on Django. We are still in the exploratory stages, and I am trying to find the best way to lay the project/development environment out. My initial idea is to develop the system as a Django "app", which contains sub-applications to separate out the different parts of the system. The reason I intended to make these "sub" applications is that they would not have any use outside the parent application whatsoever, so there would be little point in distributing them separately. We envisage that the portal will be installed in multiple locations (at different universities, for example) so the main app can be dropped into a number of Django projects to install it. We therefore have a different repository for each location's project, which is really just a settings.py file defining the installed portal applications, and a urls.py routing the urls to it. I have started to write some initial code, though, and I've come up against a problem. Some of the code that handles user authentication and profiles seems to be without a home. It doesn't conceptually belong in the portal application as it doesn't relate to the portal's functionality. It also, however, can't go in the project repository - as I would then be duplicating the code over each location's repository. If I then discovered a bug in this code, for example, I would have to manually replicate the fix over all of the location's project files. My idea for a fix is to make all the project repos a fork of a "master" location project, so that I can pull any changes from that master. I think this is messy though, and it means that I have one more repository to look after. I'm looking for a better way to achieve this project. Can anyone recommend a solution or a similar example I can take a look at? The problem seems to be that I am developing a Django project rather than just a Django application.

  • How do I use Google protobuf to communicate over a serial port?

    - by rob
    I'm working on a project that uses RXTX and protobuf to communicate with an application on a development board and I've been running into issues which implies that I'm likely doing things the wrong way. Here's what I currently have for writing the request to the board (the read code is similar): public void write(CableCommandRequest request, OutputStream out) { CodedOutputStream outStream = CodedOutputStream.newInstance(out); request.writeTo(outStreatm); outStream.flush(); } The OutputStream that is used is prepared by RXTX and the development board seems to indicate that data is being received, but it is getting garbled or is otherwise not being understood. There seems to be little documentation on using protobuf over a serial connection so I'm assuming that passing the OutputStream should be sufficient. Is this in fact correct, or is this the wrong way of sending the response over the serial connection?

  • iphone global variables accessed from different views

    - by Rob
    Okay, so ultimately I want a program where the user can input simple data such as their name, date of birth, address, etc. and then have that information stay through multiple views. I am having the user input their information as UITextFields but their are multiple views that they are using to input the data. Is there a way that when the user inputs data in a UITextField - then moves to another view - then returns to the original view - that the data will still be in that UITextField? I figure since there are placeholders that there must be a command to show previously written text in that field when the viewController is called. Also, for the life of me, I can't figure out how to keep these variables global. I have read in multiple areas that I should define them in the AppDelegate as a simple: NSString *userName; NSString *userDOB; But how do I assign the strings from the UITextFields in a different view to these variables and then re-assign them to the UITextFields when the user returns to the place where they originally input them? (I apologize if I am not explaining this coherently - I am a bit of a newb)

  • Implementing a 2 Legged OAuth Provider

    - by Rob Wilkerson
    I'm trying to find my way around the OAuth spec, its requirements and any implementations I can find and, so far, it really seems like more trouble than its worth because I'm having trouble finding a single resource that pulls it all together. Or maybe it's just that I'm looking for something more specialized than most tutorials. I have a set of existing APIs--some in Java, some in PHP--that I now need to secure and, for a number of reasons, OAuth seems like the right way to go. Unfortunately, my inability to track down the right resources to help me get a provider up and running is challenging that theory. Since most of this will be system-to-system API usage, I'll need to implement a 2-legged provider. With that in mind... Does anyone know of any good tutorials for implementing a 2-legged OAuth provider with PHP? Given that I have securable APIs in 2 languages, do I need to implement a provider in both or is there a way to create the provider as a "front controller" that I can funnel all requests through? When securing PHP services, for example, do I have to secure each API individually by including the requisite provider resources on each? Thanks for your help.

  • How to use the buffer on SocketAsyncEventArgs object

    - by Rob
    We're stuck with using buffers on the SocketAsyncEventArgs object. With the old socket method we'd cast our state object, like this: clientState cs = (clientState)asyncResult.AsyncState; However, the 3.5 framework is different. With have strings arriving from the client in chunks and we can't seem to work out how the buffers work so we can process an entire string when we find a char3. Code at the moment: private void ProcessReceive(SocketAsyncEventArgs e) { string content = string.Empty; // Check if the remote host closed the connection. if (e.BytesTransferred > 0) { if (e.SocketError == SocketError.Success) { Socket s = e.UserToken as Socket; //asyncResult.AsyncState; Int32 bytesTransferred = e.BytesTransferred; // Get the message received from the listener. content += Encoding.ASCII.GetString(e.Buffer, e.Offset, bytesTransferred); if (content.IndexOf(Convert.ToString((char)3)) > -1) { e.BufferList = null; // Increment the count of the total bytes receive by the server. Interlocked.Add(ref this.totalBytesRead, bytesTransferred); } else { content += Encoding.ASCII.GetString(e.Buffer, e.Offset, bytesTransferred); ProcessReceive(e); } } else { this.CloseClientSocket(e); } } }

  • iphone UITextField remembering user's previous input???

    - by Rob
    Is there a way to remember what the user put into a UITextField and have it displayed the next time they come to that UITextField? i.e. - have them input their name the first time they come to the "Name" UITextField but have that name already displayed in that field the next time they come across that UITextField? I want the name to still be editable if they come back to the UITextField, but inputted nonetheless in case they don't need to change it the second time around.

  • How can I get controller type and action info from a url or from route data?

    - by Rob Levine
    How can I get the controller action (method) and controller type that will be called, given the System.Web.Routing.RouteData? My scenario is this - I want to be able to do perform certain actions (or not) in the OnActionExecuting method for an action. However, I will often want to know not the current action, but the "root" action being called; by this I mean I may have a view called "Login", which is my login page. This view may include another partial view "LeftNav". When OnActionExecuting is called for LeftNav, I want to be able to determine that it is really being called for the "root" aciton of Login. I realise that by calling RouteTable.Routes.GetRouteData(actionExecutingContext.HttpContext), I can get the route for the "root" request, but how to turn this into method and type info? The only solution I have so far, is something like: var routeData = RouteTable.Routes.GetRouteData(actionExecutingContext.HttpContext) var routeController = (string)routeData.Values["controller"]; var routeAction = (string)routeData.Values["action"]; The problem with this is that "routeController" is the controller name with the "Controller" suffix removed, and is not fully qualified; ie it is "Login", rather than "MyCode.Website.LoginController". I would far rather get an actual Type and MethodInfo if possible, or at least a fully qualified type name. Any thoughts, or alternative approaches? [EDIT - this is ASP.Net MVC 1.0]

  • Text to MP3 using System.Speech.Synthesis.SpeechSynthesizer

    - by Rob
    I am trying to get a text-to-speech to save to an MP3. Currently I have the System.Speech.Synthesis speaking to a WAV file nicely. With New System.Speech.Synthesis.SpeechSynthesizer '.SetOutputToWaveFile(pOutputPath) This works fine .SetOutputToWaveStream(<<Problem bit>>) .Speak(pTextToSpeak) .SetOutputToNull() .Dispose() End With Now the first line commented out produces a WAV file which is nice. Currently I am trying to replace that with an MP3 output stream and not having much success. I have tried the Yeti.MMedia converter but either it isn't going to work or I haven't got it to work successfully. I have to admit here I don't know much about encodings, speeds etc. So the question I have is, does anyone know of a nice way I can say something like the following: .SetOutputToWaveStream(New MP3WriteStream(pOutputPath)) and have the SpeechSynthesizer write to the WAV which then gets converted to the MP3 and ends up on the HDD.

  • C# mvc2 client side form validation with xval, prevent post

    - by Rob
    I'm using xval to use client side validation in my asp.net mvc2 webapplication. Despite the errors it's giving when i enter text in a nummeric field it still tries to post the form to the database. The incorrect values are being replaced by 0 and saved to the database. But instead it shouldn't even be possible to try and submit the form. Can anyone help me out here? I've set the attributes as below; [Property] [ShowColumnInCrud(true, label = "FromPriceInCents")] [Required] //[Range(1, Int32.MaxValue)] public virtual Int32 FromPriceInCents{ get; set; } The controller catching the request looks as below; I'm getting no errors in this part. [AcceptVerbs(HttpVerbs.Post)] [Transaction] [ValidateInput(false)] public override ActionResult Create() { //some foo happens } My view looks like below; <div class="label"><label for="Price">FromPrice</label></div> <div class="field"> <%= Html.TextBox("FromPriceInCents")%> <%= Html.ValidationMessage("product.FromPriceInCents")%></div> And at the end of the view i have the following rule which in html code generates the correct validation rules <%= Html.ClientSideValidation<Product>("Product") %> I hope someone can helps me out with this issue, thanks in advance!

  • Coda Snippet Sync

    - by Rob
    Hi all, I've been trying to rack my head around making a coda plugin for syncing coda's clips to snipplr.com, coda is such a great app, but the inability to sync my hand crafted snippets is really irritating especially when you are out and about with a laptop! I was wondering if anyone has any experience in developing such a plugin, or even had any success with syncing snippets across computers? Hope you guys can help!
