  • Notification when popup is closed using Silverlight's HtmlPage.PopupWindow()

    - by Dan Auclair
    I am popping up an HTML page from a Silverlight application using the HtmlPage.PopupWindow() method. I am trying to handle the event of when the popup window is closed from within Silverlight. This is how I am attempting to do this: var window = HtmlPage.PopupWindow(new Uri("http://mypopup..."), "popup", options); EventHandler<HtmlEventArgs> windowClosed = (sender, e) => { // would like to refresh the page when popup is closed... HtmlPage.Document.Submit(); }; window.AttachEvent("onUnload", windowClosed); However the event handler never seems to get called. Is this something that is possible or am I missing something? The Silverlight app and the HTML popup page are on the same domain, however they are actually on different ports. I was thinking that maybe the pages being on different ports would be considered a cross-site restriction and cause the JavaScript to fail.

  • Best approach for GPGPU/CUDA/OpenCL in Java?

    - by Frederik
    General-purpose computing on graphics processing units (GPGPU) is a very attractive concept to harness the power of the GPU for any kind of computing. I'd love to use GPGPU for image processing, particles, and fast geometric operations. Right now, it seems the two contenders in this space are CUDA and OpenCL. I'd like to know: Is OpenCL usable yet from Java on Windows/Mac? What are the libraries ways to interface to OpenCL/CUDA? Is using JNA directly an option? Am I forgetting something? Any real-world experience/examples/war stories are appreciated.

  • JSON on IE6 (IE7)

    - by David Thorisson
    Sorry for my inpatience but after weeks staying up late and just having put my web online, I just don't have any left energy to debug... I just can't Google how to implement JSON on IE6 & IE7... I'm using JSON.stringify(...) From what I understand JSON is not built in on IE6-7 and has to be dynamically added in in-line code... how do you do that? I already have jQuery - is it my correct understanding that their JSON engine relies on the browser native one? Then some comment on invalid JSON code that makes IE6-7 fail, but I thought it wasn't native in IE6-7? Anyone?

  • How to render a partial and and a javascript file in the same time in Rails ?

    - by master2004
    Hi. My main intention is to keep the functionality independent form the Javascript, to have it gracefully degradable. Maybe I am trying to go where I want the wrong way but the main idea is: there are some jQuery UI tabs and when the user presses a link, a new tab is added corresponding to that action $("#tabs").tabs('add', "/groups", "My Groups"); the controller identifies the AJAX request and renders only the partial for that tab if request.xhr? render :partial => "index_tab" end at this point I would like the Javascript file associated with the /groups/index action to be executed as well, meaning the index.js.erb file in the groups folder. because of the "only one render" rule I couldn't think of a nice way to do it and I am in need of a fast solution. Thank you for any suggestions you might have.

  • First TDD, Simple 2-tier C# Project - what do I unit test?

    - by Joel
    This is probably a stupid question but my googling isn't finding a satisfactory answer. I'm starting a small project in C#, with just a business layer and a data access layer - strangely, the UI will come later, and I have very little (read:no) concept / control over what it will look like. I would like to try TDD for this project. I'm using Visual Studio 2008 (soon to be 2010), I have ReSharper 5, and nUnit. Again, I want to do Test-Driven Development, but not necessarily the entire XP system. My question is - when and where do I write the first unit test? Do I only test logic before I write it, or do I test everything? It seems counter-productive to test things that have no reason to fail (auto-properties, empty constructors)...but it seems like the "No new code without a failing test" maxim requires this. Links or references are fine (but preferably to online resources, not books - I would like to get started ASAP). Thanks in advance for any guidance!

  • Validation in asp.net MVC - validation only to happen when "asked"

    - by jeriley
    I've got a slightly different validation requirement than the usual "when save, validate!". The system can allow someone to update a bunch of times without being "bothered" with a validation listing UNTIL they say it's complete. I thought I might be able to pull a fast one and put the [HandleError] on the method of which this would fire, but that validates every save. Is there an attribte I can put into my custom validator that can handle this or am I going to have to write up my own HandleError attribute?

  • Graphviz DOT arrange Nodes in circles

    - by Ivo Wetzel
    OK here's my problem, I'm generating a graph of a python module, including all the files with their functions/methods/classes. I want to arrange it so, that nodes gather in circles around their parent nodes, currently everything is on one gargantuan horizontal row, which makes the thing 50k pixels wide and also let's the svg converter fail(only renders about the half of the graph). I went trough the docs(http://www.graphviz.org/doc/info/attrs.html) but couldn't find anything that seems to do the trick. So the question is: Is there a simple way to do this or do I have to layout the whole thing by myself? :/

  • Good projects to learn OCaml and F#

    - by Yin Zhu
    After learning the basic syntax, reading some non-trivial code is a fast way to learn a language. We can also learn how to design a library/software during reading others' code. I have following lists. A Chess program in OCaml by Tomek Czajka. Hal Daumé has written several machine learning libraries in Ocaml. Including decision trees, logistic regression and SVM. All of them are near-production-quality code. A Chess Game Analysis program in F# in Microsoft Research. The above three are my favorites. Will you suggest some other sources? General purpose open source software are good, specialized open source like the three I list here are even more welcome.

  • Is TDD broken in Python?

    - by Konstantin
    Hi! Assume we have a class UserService with attribute current_user. Suppose it is used in AppService class. We have AppService covered with tests. In test setup we stub out current_user with some mock value: UserService.current_user = 'TestUser' Assume we decide to rename current_user to active_user. We rename it in UserService but forget to make change to its usage in AppService. We run tests and they pass! Test setup adds attribute current_user which is still (wrongly but successfully) used in AppService. Now our tests are useless. They pass but application will fail in production. We can't rely on our test suite == TDD is not possible. Is TDD broken in Python?

  • Shadow volume shader optimization (GLSL)

    - by Soubok
    I wondering if there is a way to optimize this vertex shader. This vertex shader projects (in the light direction) a vertex to the far plane if it is in the shadow. void main(void) { vec3 lightDir = (gl_ModelViewMatrix * gl_Vertex - gl_LightSource[0].position).xyz; // if the vertex is lit if ( dot(lightDir, gl_NormalMatrix * gl_Normal) < 0.01 ) { // don't move it gl_Position = ftransform(); } else { // move it far, is the light direction vec4 fin = gl_ProjectionMatrix * ( gl_ModelViewMatrix * gl_Vertex + vec4(normalize(lightDir) * 100000.0, 0.0) ); if ( fin.z > fin.w ) // if fin is behind the far plane fin.z = fin.w; // move to the far plane (needed for z-fail algo.) gl_Position = fin; } }

  • WPF - Render text in Viewport3D

    - by eWolf
    I want to present up to 300 strings (just a few words) in a Viewport3D - fast! I want to render them on different Z positions and zoom in and out fluently. The ways I have found so far to render text in a Viewport3D: Put a TextBlock in a Viewport2DVisual3D. This guy's PlanarText class. The same guy's SolidText class. Create my own 2D panel and align TextBlocks on it. Call InvalidateArrange() every time I update the camera position. All of these are extremely slow and far apart from zooming fluently even with 10 strings only. Does anyone have a solution for this handy? It's got to be possible to render some text in a Viewport3D without waiting seconds!

  • Cassandra and asp.net (C#)

    - by Sergey Osypchuk
    I am interested to create portal on cassandra services, since I faced some performance and scale issues starting from 1 million of records. Definitely, it could be solved, but I am interested on other options. My main issues is cost of updating all necessary indexes, to make reading fast. First, is cassandra is good way for asp.net programmers? I mean, maybe there is some other projects, which worth to take a look And second, can you provide any documentation samples on how to start with cassandra programming from C#?

  • Unable to sync custom authentication with RIA services in SL3 + RIA implementation

    - by Nair
    I am developing SL3 + RIA services with custom authentication. I followed the example in http://code.msdn.microsoft.com/RiaServices/Release/ProjectReleases.aspx?ReleaseId=2661 to implement custom authentication. Based on the implementation, you first do login request from client to service. This request is async process. Noe the client GUI will start to bind data to SL controls using RIA services, which requires the authentication to be successful (by adding [RequireAuthentication] attribute). The trouble is, since you requested login from the main process, while it is doing authentication, the page control takes over and starts to bind data using RIA services. But the problem is authentication is not completed yet thus which ever the first service method data binding hits will fail with 'Access denied'. Bottom line is GUI is will not wait for authentication to be completed to start the data binding. My question is how do you handle this situation? Thanks,

  • WPF slow to start on x64 in .NET Framework 4.0

    - by Robert Fraser
    I've noticed that if I build my WPF application for Any CPU/x64, it takes MUCH longer to start (on the order of about 20 seconds) or to load new controls than it does if started on x86 (in release & debug modes, inside or outside of VS). This occurs with even the simplest WPF apps. The problem is discussed in this MSDN thread, but no answer was provided there. This happens only with .NET 4.0 -- in 3.5 SP1, x64 was just as fast as x86. Interestingly, Microsoft seems to know about this problem since the default for a new WPF project in VS2010 is x86. Is this a real bug or am I just doing it wrong? EDIT: Possibly related to this: http://stackoverflow.com/questions/2788215/slow-databinding-setup-time-in-c-net-4-0. I'm using data binding heavily.

  • Is AlarmManager.setRepeating idempotent?

    - by tardate
    In my android app, I'm setting an alarm that I want to occur repeatedly, hence using AlarmManager.setRepeating(). I don't want to keep track of whether the alarm is set myself (sounds like a bad idea that's prone to fail at some point), and there seems to be no API support for checking whether a particular alarm is already set for a given Intent. Hence, I am pessimistically resetting the alarm each time my app activates: alarmManager.cancel(pendingIntent); ... alarmManager.setRepeating(..., pendingIntent); Question: is calling setRepeating() idempotent i.e. do I need to explicitly cancel() any prior alarm or can I safely just call setRepeating() and be done with it?

  • rename file names from lower case to upper case

    - by Adnan
    Hello, I have about 2k of file that are currently in lower case like: file_one.cfr file_two.cfr .... I am searching for a fast way to rename them to upper case so they would be like; FILE_ONE.cfr FILE_TWO.cfr .... If I use from my shell; for i in *; do mv $i `echo $i | tr [:lower:] [:upper:]`; done I can get all file and the file extensions to upper case. But the extension should remain in lowercase, so my approach does not work. Any programming language is welcome.

  • Works in firefox but not IE8

    This is working fine in firefox but only closes the first page and then breaks in IE8. Firebug in IE8 says that x.item(o) is null. I can't figure out why this works in firefox but not IE. Thanks for any help. pager(x=document.getElementsByName("pg1")); function pager( x ) { var curr = document.getElementById('showing'); $(curr).fadeOut('fast'); curr.id = 'hide'; $(x).fadeIn('slow'); x.item(0).id ='showing'; }

  • Is gchart safe to use?

    - by Paul Tomblin
    The home page for gchart, a client side charting add-in for Google Web Toolkit (GWT), has a long screed about how the project's only maintainer thinks his Google account has been hacked and because of that he will be "disavowing/abandoning my own project and Google account". Does that mean the project is an orphan? Is somebody taking it over? There is always a risk on basing your project on somebody else's code because they may stop supporting it or abandon it during your project's life time, but it seems to me that with the fast evolution of Java and GWT, using gchart in a new project may be a big mistake. Am I right?

  • UIScrollView and UIImage in it with paging enabled

    - by Infinity
    Hello guys! I need to display 10 - 1000 images on a UIScrollView. Paging is enabled. So every page of the scrollview is an image, it is an uiimage. I can load 10 images to 10 uiimages which stays in the memory, but with 1000 images I have problems on the iPhone or on the iPad. I am trying to unload and then load the images when I am doing scrolling. I every time displays 3 images. The current page image, and the -1 and +1 pages. When I am scrolling I unload the image and then load the next. With this method I have two problems. The scrolling is laggy and if I scroll very fast the images don't appear. Maybe is there any good solution for these problems? Can you suggest me one?

  • Redirecting stdin through a FIFO

    - by kaoD
    I'm running a server app (written in Java) under GNU/Linux which takes input (from stdin, I guess) and interprets it to run some commands. I dont want to run the app inside a terminal window (I'd like to run a daemon), but I'd still like to be able to input commands whenever I want to. I thought I might be able to do that using fifos, so I created it using mknod. The problem is cat fifofile java... and cat fifofile | java ... fail with a "file not found" error for some reason. Using only cat to read and write and the fifo works flawlessly. Is there any way to fix this, or any other way to achieve the same goal?

  • Pass by reference in Boost::Python

    - by Fabzter
    Hi everybody. Consider something like: struct Parameter { int a; Parameter(){a = 0} void setA(int newA){a = newA;} }; struct MyClass { void changeParameter(Parameter &p){ p.setA(-1);} }; Well, let's fast forward, and imagine I already wrapped those classes, exposing everything to python, and imagine also I instantiate an object of Parameter in the C++ code, which I pass to the python script, and that python script uses a MyClass object to modify the instance of Parameter I created at the beginning in the C++ code. After that code executes, in C++ Parameter instance is unchanged!!! This means it was passed by value (or something alike :S), not by reference. But I thought I declared it to be passed by reference... I can't seem to find Boost::Python documentation about passing by reference (although there seems to be enough doc about returning by reference...). Can anyone give some hint or pointer please?

  • ExtJS: Login with 'Remember me' functionality

    - by Chau
    I'm trying to create a simple login window with the very common 'Remember me' functionality. The login validation is done AJAX style, thus the browser won't remember my input. My approach is to use the built-in state functionality, but how to use it confuses me. Ext.state.Manager.setProvider(new Ext.state.CookieProvider({ expires: new Date(new Date().getTime()+(1000*60*60*24*7)), //7 days from now })); ... { xtype: 'textfield', fieldLabel: 'User name', id: 'txt-username', stateful: true, stateId: 'username' }, { xtype: 'textfield', fieldLabel: 'Password', id: 'txt-password', inputType: 'password', stateful: true, stateId: 'password' }, { xtype: 'button', text: 'Validate', stateEvents: 'click' } I know I have to implement the getState method, but on what component (my guess is on the two textfields)? Another thing I fail to realize is, how is my click event on the button connected to the state properties of my textfields?

  • Embed VLC player in GWT

    - by chrisnfoneur
    Hello, I want to embed a VLC player in my webapp build with Google's GWT. First I had a look at this page: http://wiki.videolan.org/GWT, which offers a nice solution but I add to implements all javascript functions calls (play, stop, fullscreen) with JSNI. Then I found gwt-player (hosted by Google code) which does all the job for me but the annoying part is that the project is not widely used (few posts each month on the project's group, not so many talks about it in blogs/forums...) Do you know another option to easly embed & control a VLC player in a GWT app ? My main goal is to play any video/audio file in a webapp and offer the user a fast/forward feature (set rate in VLC), is there any other player I could use ? I already had a look at Quicktime, Windows Media player & Flowplayer, none of them offers as much features as VLC. Thanks in advance & have a nice new year's eve. Chris
