  • Simple Java Applet not loading in FireFox / Safari on MacOS

    - by Sleepless
    Hello all, I'm probably missing something very basic here. I'm trying to get my first applet to run inside a local HTML page in Firefox 3.6 on Mac OS 10.5.8. Here's the applet's code: package SimpleApplet; import java.applet.Applet; import java.awt.*; public class MyApplet extends Applet { private static final long serialVersionUID = 1L; public void init() { } public void stop() { } public void paint(Graphics g) { g.drawString("Tweedle-Dee!",20,40); } } Here's the HTML page: <html> <body> Here's the applet: <br/> <applet code="MyApplet.class" width="300" height="150"> </applet> </body> </html> Both files (.class and .html) are in the same folder on my local machine. Now when I load the .html file into Firefox, a rectangle with a red X gets displayed. The applet works when started from Eclipse (using JRE 1.5 BTW). Also, it's not a general problem with my browser, as several pages with applets (e.g. http://java.sun.com/applets/jdk/1.4/demo/applets/Blink/example1.html) work. This is also difficult to troubleshoot because there is no output at all on the Java console... Any suggestions are appreciated!

  • Facebook Connect for simple authentication?

    - by Starnzy
    Hi I have an ASP.net website which I want to introduce 'Facebook Connect' functionality into, purely for account login/creation purposes. I want a user to be able to click the 'Login using Facebook' type button, and to then log that user into my website based on a userid lookup from the Facebook response. I have a couple of questions surrounding this: Presumeably I can do all of this using the Facebook API - without the need for an actual pretty public facing 'application' on Facebook? I simply want to utilise the Facebook API for authenticating an account. I'm not interested in creating some app for doing something 'within' facebook itself. I have located some code snippets online and tried using the Facebook Developer Toolkit, calling the getInfo method, and whilst it does come back to my website with a uid, none of the other user information is present within the response, like Email, Name etc. The uid is the only populated field in the response. Here is the code I use: if (ConnectAuthentication.isConnected()) { API api = new API(); api.ApplicationKey = ConnectAuthentication.ApiKey; api.SessionKey = ConnectAuthentication.SessionKey; api.Secret = ConnectAuthentication.SecretKey; api.uid = ConnectAuthentication.UserID; //Display user data captured from the Facebook API. facebook.Schema.user facebookUser = null; try { facebookUser = api.users.getInfo(); User user = new User(); user.FacebookUser = facebookUser; user.IsFacebookUser = true; return user; } catch { return null; } } else { return null; } Can anyone please help with either/both of these queries? Thanks in advance...

  • Simple NSTableView bindings example

    - by sirjorj
    I am trying to populate a 2-column NSVTableView via bindings, but the data is not showing up in the table. In XCode: I have a NSMutableArray in my AppDelegate that will hold the data, as well as the corresponding @property and @synthesize. On an event, I call [removeAllObjects] on the NSMutableArray and repopulate it with some NSDictionary objects. Each dictionary contains 2 KVP's: a NAME and a VALUE. In IB: I added an NSArrayController and bound it's Content Array to my AppDelegate and set the ModelKeyPath to the name of the NSMutableArray in the AppDelegate. On the NSTableView, I bound the Content to the ArrayController. ControllerKey = "arrangedObjects", ModelKeyPath = empty. For each of the two columns, I bound the Value to the AppController and set the ModelKeyPaths to NAME and VALUE respectively. ControllerKey = "ArrangedObjects". I have tried several other things, such as using an NSArray in the app delegate and making a new one every time I need to update the values. There must be some tiny little thing I am forgetting. What is it? jorj

  • Ruby PTY.spawn is Hanging - How to fill out Email and Password in simple example

    - by viatropos
    After asking this question, it looks like I need to use Ruby's PTY Module, of which there is no documentation. I have written this code to try to push content to Google App Engine because the python command sometimes asks me for my username and password. But when I run this code, it just hangs. cmd = "appcfg.py update cdn" PTY.spawn("#{cmd} 2>&1") do | input, output, pid | begin input.expect("Email:") do output.write("#{credentials[:username]}\n") end input.expect("Password:") do output.write("#{credentials[:password]}\n") end rescue Exception => e puts "GAE Error..." end end What am I missing here? How can I get this to work?

  • Form Validation using Java inside PHP

    - by Mikey1980
    I have a simple problem but no matter what I try I can't see to get it to work. I have a form on a php page and I need to validate the qty value on my form so that it doesn't exceed $qty (value pulled from mySQL) and is not less than zero. Sounds easy--hmm wish it were..lol! I had it checking if the value was numeric and in my attempts to make this work I even broke that--not a good morning..lol! Here's a snip of my Java Fn: <script type='text/javascript'> function checkQty(elem){ var numericExpression = /^[0-9]+$/; if(elem.value.match(numericExpression)){ return true; }else{ alert("Quantity for RMA must be greater than zero and less than original order!"); elem.focus(); return false; } } </script> The function is called from the submit button, onClick: <input type="submit" name="submit" onclick="checkQty(document.getElementById('qty')";"> I've tried: var numericExpression = /^[0-9]+$/; if(elem.value.match(numericExpression) || elem.value < 0 || elem.value > <? int($qty) ?>){ No dice....HELP!?!

  • How can Perl interact with an ajax form

    - by Jeff
    I'm writing a perl program that was doing a simple get command to retrieve results and process them. But the site has been updated and now has a java component that handles the results (so the actual data is not in the source code anymore). This is the site: http://wro.westchesterclerk.com/legalsearch.aspx Try putting in: Index Number: 11103 Year: 2009 I want to be able to pro grammatically enter the "index number" and "year" at the bottom of the form where it says "search by number" and then retrieve the results listed next to it. I've written many programs in Perl that simply pass variables via the URL and the results are listed in the source code, so it's easy to parse. (Using LWP:Simple) Like: $html = get("http://www.url.com?id=$somenum&year=$someyear") But this is totally new to me and I don't know where to begin. I'm somewhat familiar with LWP:UserAgent and Mechanize. I'd really appreciate any help. Thanks!

  • I need a simple command line program to transform XML using XSLT

    - by fuzzy lollipop
    I am on OSX Snow Leopard (10.6.2) I can install anything I need to. I would preferably like a Python or Java solution. I have searched on Google and found lots of information on writing my own program to do this, but this is a just a quick and dirty experiment so I don't want to invest a lot of time on writing a bunch of code to do this, I am sure someone else has done this already.

  • simple regex to splice out text in ruby

    - by user141146
    I'm using ruby and I want to splice out a piece of a string that matches a regex (I think this is relatively easy, but I'm having difficulty) I have several thousand strings that look like this (to varying degrees) my_string = "adfa <b>weru</b> orua fklajdfqwieru ofaslkdfj alrjeowur woer woeriuwe <img src=\"/images/abcde_111-222-333/111-222-333.xml/blahblahblah.jpg\" />" I would like to splice out the /111-222-333.xml (the value of this changes from string to string, but suffice it to say is that I want to remove the piece between 2 forward slashes that contains something.xml. my hope was to find a match like this my_match = my_string.match(/\/.+?\.xml\//) but this actually captures "/b> orua fklajdfqwieru ofaslkdfj alrjeowur woer woeriuwe <img src=\"/images/abcde_111-222-333/111-222-333.xml/" I assumed that .+? would match what I am looking for, but it seems like it starts with the first forward slash that it finds (even though it's non-greedy) and then expands forward to the ".xml"). Any thoughts on what I'm doing wrong? TKS!!

  • Need simple advice for graph solving problem

    - by sap
    Hi there, a collegue of mine proposed to me an exercise from an online judge website, which is basically a graph solving problem of an evacuation plan on a small town. i dont need the answer (nor do i want it) i just need an advice on which is the best approach to solving it since im kinda new to these kind of problems. the problem consists of town buildings with workers and fallout shelters in case of a nuclear attack. i have to build an algorithm that will assign the workers of each building to one or more fallout shelters but in a way that some shelters wont became too overcrowded while others remain almost empty (else i would just make the workers go to the nearest one). the problem is this: http://acm.timus.ru/problem.aspx?space=1&num=1237 in case its offline heres the google cached version of it: http://webcache.googleusercontent.com/search?q=cache:t2EPCzezs7AJ:acm.timus.ru/problem.aspx%3Fspace%3D1%26num%3D1237+vladimir+kotov+evacuation+problem&cd=1&hl=pt-PT&ct=clnk&gl=pt what i've done so far is for each building get the nearest shelter and move the number of workers from that build equal to the shelter capacity. then move to the next building. but sometimes the number of workers is greater than the shelter capacity, in that case after i iterate through every building, ill just iterate then again apllying the same algorithm until every building has 0 workers in it, problem is this is hardly the best way to solve it. any tip is welcome, please dont feel like im asking for the answer, i just want an advice in the right direction of solving it. thanks in advance.

  • Best Practice - Validating Input In Simple GUI Application?

    - by Alex
    I'm writing a GUI app with wxwidgets in C++ for one of my programming classes. We have to validate input and throw custom exceptions if it doesn't meet certain conditions. My question is, what is best practice when it comes to this? Should I write a seperate function that checks for errors, and have my event handler's call that function? Or should I do my error-checking in my event handlers? Or does it really matter? Thanks!

  • Android ==> Simple 2d Animation ???

    - by aryaxt
    public void MoveMyButton (int x) //where the button suppose to move to { TranslateAnimation anim=new TranslateAnimation(this.getLeft() ,x, this.getTop() ,20)); anim.setFillAfter(true); anim.setDuration(1000); this.setAnimation(anim); anim.start(); } button's x at start is 1. I call the method to move it to 100, and it goes from 1 to 100 I call it to go to 200, and it goes from 1 to 200, instead of 100 to 200 Is there any way to make the animation to save the location of the button as it animates it? Thanks

  • How do I populate these fields from existing data?

    - by dmanexe
    I'm not sure how to make a few parts of my form to populate from data from an array I'm passing from the database. First is this <select> object. The key estimate_lead_id in the database holds the value, and I want the dropdown to auto-select based on the value from the database. <select name="estimate_lead_id"> <? foreach($leads->result() as $lead) { ?> <option value="<?=$lead->id?>"><?=$lead->lead_name?></option> <? } ?> </select> Second (this is a little more complex), I have created a script that loops through and gets all of the items from each respective category. What I can't get it to do though is loop through these items and only display the items in the estimate, and then fill the fields with the respective values from the database. <?php foreach ($items['items_poolconcretedecking']->result() as $item) { ?> <input type="checkbox" name="measure[<?=$item->id?>][checkmark]" value="<?=$item->id?>"> <input class="item_mult" value="" type="text" name="measure[<?=$item->id?>][quantity]" /> <?php } ?>

  • Simple Android OpenGL App Lag

    - by Eugene
    Hi, I have an Android OpenGL application which simply draws 2D squares (using 2 triangles) and animates them moving down the screen. I essentially do this by running: glLoadIdentity(), then glTranslatef, and finally glDrawElements all in a for loop. (The for loop is to draw all 10 blocks on the screen for every frame). In every drawFrame, the y-position of the blocks increments for the animation. The problem I'm having is strange. I run the application and the animation is laggy and not smooth. Then I re-run the application and I get a smooth animation. If I run again, I may get a smooth animation, or possibly not. Is my method correct, or is there a better way of doing this animation? Thanks for the help!

  • Rails does not display error messages on a form in a custom method

    - by slythic
    Hi all, I've created a custom method called checkout in my app. I create an order (which is done my adding products to my "cart"), assign it to my client, and then I head to my checkout screen where I confirm the items and enter their customer order number and complete the order (submit). Everything works great except that it doesn't display error messages. I'm able to display a flash error notice (seen in complete_order method) when things go wrong but it doesn't specify the details like a normal form would. The error messages should appear if the customer order number is not unique for that client. Below is the custom method (checkout) related code. Order Model: validates_uniqueness_of :customer_order_number, :scope => :client_id Orders_controller: def checkout @order = current_order end def complete_order @order = current_order respond_to do |format| if @order.update_attributes(params[:order]) @order.complete #sets submitted datetime and state to 'complete' flash[:notice] = 'Thank you! Your order is being processed.' format.html { redirect_to( products_path ) } format.xml { head :ok } else flash[:error] = 'Please review your items' #added to confirm an error is present format.html { redirect_to( checkout_path ) } format.xml { render :xml => @order.errors, :status => :unprocessable_entity } end end end And the form in the checkout view: <% form_for @order, :url => { :controller => "orders", :action => "complete_order" } do |f| %> <%= f.error_messages %> <%= f.text_field :customer_order_number, :label => "Purchase Order Number" %> <p> <%= f.submit 'Complete Order', :confirm => 'Are you sure?' %> <small> or <%= link_to 'cancel', current_cart_path %></small> </p> <% end %> Any idea how I can display the specific error messages? Thank you in advance! -Tony

  • Simple Prototype.js code to select multiple elements with the same classname

    - by stephemurdoch
    I have one link with an id of "link", and I use the javascript below to open that link up in a modalbox: #In my template I have: <a href="some/path" id="link">link</a> #Then in my application.js file I have: document.observe('dom:loaded', function() { $('login-link').observe('click', function(event) { event.stop(); Modalbox.show(this.href,{title: 'some title', width: 500}); }); }) Since id's must be unique, this javascript only works for one element per page so I use it to observe my login-link and it has served me well. Until now. I want to use the same javascript to observe multiple links which have classnames instead of id's as below: <a href="link/to/some/stuff" class="link">link 1</a> <a href="link/to/some/other/stuff" class="link">link 2</a> When I do this, I can't get any of the links to open in a modalbox. If I change the class to an id for each link, then I can get the first link in the list to open in a modalbox. I've tried to use the '$$' notation to build an array of links in my javascript (shown below) but if I do that, then none of the links open correctly #document.observe method removed for display purposes $$('link').observe('click', function(event) { event.stop(); Modalbox.show(this.href,{title: 'some title', width: 500} ); }); My javascript skills obviously suck. Does anyone know how to fix the problem?
