  • How to access the user font settings of the Internet Explorer?

    - by Mil
    I would like to access the Internet Explorer user settings for fonts, especially the font family, within a Browser Helper Object written in C#. I have looked into SHDocVw.WebBrowser and IHTMLDocument( to 5) but I don't see what I'm looking for or missing the property. The BHO is for Internet Explorer 7. Thank you very much! Edit: Richard asks why I need this information: The font-family you can adjust in the IE7 settings is used if the given font-families by the HTML document or CSS are not installed on the system. I need this application-based font-family which is used to render the text in the last instance (if all other information fail).

  • Rails, Edit page update in a window

    - by Mike
    I have my code working so that I have a table of businesses. There's a pencil icon you can click on the edit the business information. The edit information comes up in a partial inside of a modal pop up box. The only problem is that once they make the changes they want and click update, it sends them to the 'show' page for that business. What I want to happen is have the pop up box close and have it update the information. This is my update function in my controller. def update @business = Business.find(params[:id]) respond_to do |format| if @business.update_attributes(params[:business]) flash[:notice] = 'Business was successfully updated.' format.html { redirect_to(business_url(@business)) } format.js else format.html { render :action => "edit" } format.xml { render :xml => @business.errors, :status => :unprocessable_entity } end end end I tried following railscast 43 and i created an .rjs file but I couldn't get that to work at all. My update was still taking me to the show page. Any help would be appreciated. EDIT: Added some more code. <% form_for(@business) do |f| %> <%= f.error_messages %> <p> <%= f.label :name %><br /> <%= f.text_field :name %> </p> ... <%= f.label :business_category %><br /> <%= f.select :business_category_id, @business_categories_map, :selected => @business.business_category_id %> </p> <p> <%= f.label :description %><br /> <%= f.text_area :description %> </p> <p> <%= f.submit 'Update' %> </p> <% end %> This is my form inside of my edit page which is being called through the index in a pop up by: <div id="popupEdit<%=h business.id %>" class="popupContact"> <a class="popupClose<%=h business.id %>" id="popupClose">x</a> <% if business.business_category_id %> <% @business = business %> <%= render "business/edit" %> <% end %> </div>

  • Is there a buffer size attached to stdout?

    - by jameswelle
    I am trying to find some information on data limits related to stdout on Windows. I can't seem to find the information on MSDN. Is there a limit to how much data can be written to stdout? If so, what happens if the limit is reached? Is the data lost? If stdout is redirected (for example, by launching the process from .Net and using the ProcessStartInfo.RedirectStandardOutput property), does that have any effect on how much data can be written? As I read from the stdout stream in the calling process, does that affect the limitations? Are these limits related in any way to named pipes?

  • unit-testing maven plugins

    - by Don
    Hi, I'm looking for information about how to write unit tests for Maven plugins. Although there's a page on the Maven site about this topic, there's only one example unit test, which does nothing useful. I also found this wiki page, but it hasn't been updated for more than 4 years, so I'm reluctant to invest any faith in it. I checked the book "The Definitive Guide to Maven", but it doesn't even mention the subject. I'd like to write my unit tests in either Groovy or Java, and would appreciate any information about how to do this. Thanks, Don

  • How to write a custom (odd) authentication plugins for Wordpress, Joomla and MediaWiki

    - by Bart van Heukelom
    On our network (a group of related websites - not a LAN) we have a common authentication system which works like this: On a network site ("consumer") the user clicks on a login link This redirects the user to a login page on our auth system ("RAS"). Upon successful login the user is directed back to the consumer site. Extra data is passed in the query string. This extra data does not include any information about the user yet. The consumer site's backend contacts RAS to get the information about the logged in user. So as you can see, the consumer site knows nothing about the authentication method. It doesn't know if it's by username/password, fingerprint, smartcard, or winning a game of poker. This is the main problem I'm encountering when trying to find out how I could write custom authentication plugins for these packages, acting as consumer sites: Wordpress Joomla MediaWiki For example Joomla offers a pretty simple auth plugin system, but it depends on a username/password entered on the Joomla site. Any hints on where to start?

  • How to get started with embedded systems in the aircraft or submarine industries?

    - by Jason
    Hi, Not 100% sure how to frame this question but here goes... I currently work as a Rails developer but want to work on more substancial / "meaty" projects and have always been very interested in embedded systems, especially systems that run on aircraft and especially submarines.....I know strange combination. I have been doing some searching & found lockheed martin produces a lot of underwater systems for various navys around the world e.g. http://www.naval-technology.com/projects/nssn/ However, there is very little information about what software is used within these systems, what OS's they use or anything else "technical", presume there is a lot of C / C++ involved but that is just a guess... so its hard to know where to even begin learning what is required to potential work in these areas. Just wondering if anyone has any experiance working with or more information about embeddeed systems in either the airline (onboard flight systems) or especially submarine systems? Thanks!

  • How does Maven find a Artifact in a remote repository?

    - by Thomas
    I'm trying to create a maven plugin to generate a file with the URL to all the dependencies in a project. I have been able to get the dependencies and their artifact, but I'm having trouble getting the download URL. Using ArtifactResolver and ArticateMetadataSource I get some of the artifact information. However I fail to get all the information for all the dependencies. I haven't been able to find documentation on the resolution logic, so that I can call it form my plugin. I can use an ArtifactResolver to download the artifact, but what I really wanted was just the URL. The Maven Artifact API has a a method called getDownloadURL (see http://maven.apache.org/ref/2.0.4/maven-artifact/apidocs/org/apache/maven/artifact/Artifact.html). However I cant seem to find a way to get a real value into it. I always get a null value. Is there a way to have it resolved (downloading or not) and get the URL for where the file came from?

  • Java Session Like Object

    - by scriptmonster
    I have been developing a project and in this project i have designed my code to do the same job after a specified time interval continuously. The job that wanted to be done has a lot of distinct cycles. The interval is small to execute them normally thus i used threads. Until that point everything is clear for me. To decrease the process and information transaction i wanted to put an session like object that holds the given data and provide it to any thread at anytime. With this object i plan to not query the same configuration information from database at everytime but if it exists on the session take it else query and store on session. I'm not sure how to implement this structure. Regards,

  • PHP/Mysql issues

    - by queryne
    Php/my sql newbie question. I have a database I've imported into my local phpmyadmin. However it seems I can't access it from my a php application. The connection string seems right and when i try to authenticate user credentials to access database information, no problems. However authenticate everyone and knows when i put in fake credentials. Still it won't pull any other information from the database. For instance, once a users login they should see something like, "Hello username"... that kind of thing. At this point I see "Hello" without the username. Any ideas what i might be missing?

  • get url:xml why external url does not work

    - by Kazim Cubbali
    I am trying to grab information from an external xml with the following code. It only worked when I uploaded same file to my servers. Why cant I grab information from an external url? <script language="javascript"> // This script uses jQuery to retrieve the news XML file and display the contents $(document).ready(function(){ $.ajax({ type: "GET", url: "www.simplyprofound.com/samples/xml_jquery/sample.xml", dataType: "xml", success: function(xml) { $(xml).find('item').each(function(){ var title = $(this).find('title').text(); var source = $(this).find('source').text(); var description = $(this).find('description').text(); $('<div class="news_title"></div>').html(title).appendTo('#news_wrap'); $('<div class="news_source"></div>').html(source).appendTo('#news_wrap'); $('<div class="news_description"></div>').html(description).appendTo('#news_wrap'); }); } }); }); </script>

  • WCF service reference stopped generating code for one project

    - by Mike Pateras
    I have references to two different WCF services in a project. I updated the reference for one of the services, and now no code is generated for it. The references.cs file just has the "this is genrated code" comment at the top. Updating that same service in other projects and updating the other service both work fine. It's only that one service reference in this one project that's causing the problem, and I'm getting no information from Visual Studio (it just says it failed to generate code and I should look at the other errors, which provide no information). If I uncheck the "reuse types in referenced assemblies", code is generated, but I don't want to have this one project be different from the others. I'd like to solve the problem. Re-checking the reuse type option produces an empty references.cs file, again. The collection type doesn't seem to matter, either. How can I diagnose and solve this problem?

  • Php efficiency question --> Database call vs. File Write vs. Calling C++ executable

    - by JP19
    Hi, What I wish to achieve is - log all information about each and every visit to every page ofmy website (like ip address, browser, referring page, etc). Now this is easy to do. What I am interested is doing this in a way so as to cause minimum overhead (runtime) in the php scripts. What is the best approach for this efficiency-wise: 1) Log all information to a database table 2) Write to a file (from php directly) 3) Call a C++ executable, that will write this info to a file in parallel [so the script can continue execution without waiting for the file write to occur ...... is this even possible] I may be trying to optimize unnecessarily/prematurely, but still - any thoughts / ideas on this would be appreciated. (I think efficiency of file write/logging can really be a concern if I have say 100 visits per minute...) Thanks & Regards, JP

  • Shoring up deficiencies in a "home grown" programmer?

    - by JohnP
    I started out by teaching myself BASIC on a Vic 20, and in college (mid 80's) I had Fortran, Pascal, limited C, machine and assembler (With a smattering of COBOL). I didn't touch programming from approx 1989 to 1999. At that point, I was lucky enough to get hired as a Clipper programmer. Took me about 6 months to learn most of it, and by now (13 yrs) I'm pretty expert in it. I have also picked up Cold Fusion, some C#, some ASP, SQL, etc. I know programming structures, but in most languages I'm missing the esoterics, and I know my code could be much tighter. The problem is that I've learned what I needed to, to get the job done. This results in a lot of gaps in practical knowledge. I am also missing out on a TON of theory. Things like SRP, Refactoring, etc are alien terms. (Although I grok the intent after a short read). In addition, I am in the position now of teaching junior programmers the company and our software, and I don't want to pass on the knowledge gaps. I know this is somewhat of a subjective question and may be closed, but how do you go back and pick up what you've missed?

  • How can I use Perl to grab text from a web page that is dynamically generated with JavaScript?

    - by bstullkid
    There is a website I am trying to pull information from in Perl, however the section of the page I need is being generated using javascript so all you see in the source is: <div id="results"></div> I need to somehow pull out the contents of that div and save it to a file using Perl/proxies/whatever. e.g. the information I want to save would be document.getElementById('results').innerHTML; I am not sure if this is possible or if anyone had any ideas or a way to do this. I was using a lynx source dump for other pages but since I cant straight forward screen scrape this page I came here to ask about it! If anyone is interested, the page is http://downloadcenter.trendmicro.com/index.php?clk=left_nav&clkval=pattern_file&regs=NABU and the info I am trying to get is the row about the ConsumerOPR

  • Is C# development effectively inseparable from the IDE you use?

    - by Ghopper21
    I'm a Python programmer learning C# who is trying to stop worrying and just love C# for what it is, rather than constantly comparing it back to Python. I'm really get caught up on one point: the lack of explicitness about where things are defined, as detailed in this Stack Overflow question. In short: in C#, using foo doesn't tell you what names from foo are being made available, which is analogous to from foo import * in Python -- a form that is discouraged within Python coding culture for being implicit rather than the more explicit approach of from foo import bar. I was rather struck by the Stack Overflow answers to this point from C# programmers, which was that in practice this lack of explicitness doesn't really matter because in your IDE (presumably Visual Studio) you can just hover over a name and be told by the system where the name is coming from. E.g.: Now, in theory I realise this means when you're looking with a text editor, you can't tell where the types come from in C#... but in practice, I don't find that to be a problem. How often are you actually looking at code and can't use Visual Studio? This is revelatory to me. Many Python programmers prefer a text editor approach to coding, using something like Sublime Text 2 or vim, where it's all about the code, plus command line tools and direct access and manipulation of folders and files. The idea of being dependent on an IDE to understand code at such a basic level seems anathema. It seems C# culture is radically different on this point. And I wonder if I just need to accept and embrace that as part of my learning of C#. Which leads me to my question here: is C# development effectively inseparable from the IDE you use?

  • How to design this simple database?

    - by Vafello
    I have 2 tables - one storing user information (id, username, password) and the second one storing information about events (id, name, description, date, username(represents the user who created the event)). I would like to implement 'favourite events' functionality. This would allow the user to store his favourite events and later display them in a list. I am not sure how to implement this in terms of design. I need a simple solution. Something like storing the IDs of favourite events in a field in the user table. I am using mysql and php. Can anyone point me to the right direction?

  • Good practices when optimizing HTML5/Javascript Game Developement [closed]

    - by hustlerinc
    I'm just starting out as a game developer and have created a few crappy but playable clones of classic games like pong, and bomberman. Being self taught (bless the internet) I do this by just stuffing in code to make the games work. Now I feel the time has come to create something complete, for this I need to know how a game is structured. I've searched on the web but there isn't that much to be found. The only "high-level" language I know is javascript so reading a tutorial or article based on C++ doesn't help me that much. I'm looking for good resource's pedagogically covering the theory and possibly examples (in Javascript or pseudo code that is understandable for a beginner) of how the game pieces fit together. From the start screen to asset loading and running the game loop. I'm not looking for anything complicated like reading through a 4000 line source code. All I want to learn is where, how and when the main parts of every game should be called. If you know any good resources to share, or maybe even have an answer for me I would deeply appreciate it.

  • Javascript Regex multiple group matches in pattern

    - by mummybot
    I have a question for a Javascript regex ninja: How could I simplify my variable creation from a string using regex? I currently have it working without using any grouping, but I would love to see a better way! The string is: var url = 'resources/css/main.css?detect=#information{width:300px;}'; The code that works is: var styleStr = /[^=]+$/.exec(url).toString(); var id = /[^\#][^\{]+/.exec(styleStr).toString(); var property = /[^\{]+/.exec(/[^\#\w][^\:]+/.exec(styleStr)).toString(); var value = /[^\:]+/.exec(/[^\#\w\{][^\:]+[^\;\}]/.exec(styleStr)).toString(); This gives: alert(id) //information alert(property) //width alert(value) //300px Any takers?

  • How to set up a has-many relationship in Cocoa?

    - by SphereCat1
    I'm building a (very) simple FTP app in Cocoa, and I need to store information on the different types of servers that are supported. So, I've created a ServerType class, which stores all of the relevant information about a single type of server. I then have a ServerTypes class which is designed to manage all of the ServerType classes that are created. My question is how to set up the relationship between the two objects. Is there a preferred method to do so? Also, since Objective-C doesn't support non-instance classes, where should I create an instance of ServerTypes that will have to be used throughout the entire program? Or is there a better way to do that? I need it to be KVC compliant so That I can bind one of the ServerType properties to an NSPopupBox. Sorry about the large volume of questions, I'm fairly new to Cocoa and Objective-C. If you need to see code, just ask and I'll be happy to add some. :) SphereCat1

  • Watermarking Flash Videos (server-side)

    - by Roberto Aloi
    Hi all, I have a bunch of flash videos that I need to watermark with user related information, to make illegal re-distribution of these files harder. I'm wondering how can this be done server-side. If done client-side, it will be quite easy for the user to intercept the videos before they are watermarked. Since the watermark should contain user-specific information I can't really watermark the videos before encoding them (unless I have an encoded video per user - not feasible). I'm expecting this to affect the streaming performances a lot, though. Any idea how this can be done (possibly in an efficient way)?

  • Facebook login on headless browser

    - by dmni
    My Facebook app has a function of automating tasks on server side headless browser (like visiting app links). Now, I use the Facebook SDKs to log user in and access user's news stream to search for links and other information. Once the app has found all the links, it is supposed to pass this information in to the headless browser which will then proceed to visit in them for example. The problem is that these headless browser windows' are not logged in. I would like the headless browser to be temporary logged in as the user launching the tasks from the app. Is this possible?

  • Running OpenMPI on Windows XP

  • Dropping the full-time high-pay gig - I need help choosing a smart path that I can rely on to produce enough to survive comfortably ($2,500 per month)

    - by Jeff V
    I have about 6 years of full time experience developing web applications and tools. I know perl, python, PHP, ruby, and a good deal of SQL and relational theory. I have never had to choose a self-employed path as I have always had full time work or a bank account (credit cards) to support a big project. I'm planning to move out of the country to an area that will not offer local employment, and need some advice on what to focus on. I want to move in no more than six months, I have enough savings to live for an additional six months, but I would like to conserve it as much as possible. I enjoy taking risks, so I'm not looking for discussion of whether this is a good idea or not. I want advice on the most reliable solution given my skill set. Some paths I'm considering: Learn objective-c and build quality Apple software. Develop subscription based web tools for SEO, or other Marketing applications Attempt to acquire freelance projects by developing a reputation within open source projects, freelancer.com, and other online communities The last time I left my job, I was building a startup (that went under), and missed out living in a beautiful place due to the amount of time I worked. I would like to work 30-40 hours per week max. I can dedicate 10-15 hours per week while at my current job to prepare and learn. A preemptive thanks for the advice...
