  • Do employers hiring for Software jobs care about the classes you took in CS masters program?

    - by Joey Green
    I'm torn between two classes right now for next semester( Software Design and Advanced Computer Graphics ). I would enjoy Advanced Computer Graphics more, but I feel the software design class would help me when approaching anything I ever build for the rest of my career. I feel though I could just buy the book( I already have both books actually ) of the Software Design class and go through it, if I wanted. But think it would be a bit tougher to pick up the Advanced Computer Graphics class on my own. So do employers look at the graduate classes you've taken to decide if you would be a good fit or not? I think more importantly what I'm wanting to know is if I wanted to work for a high-end software company like Apple or Google would a company like that be more impressed by someone that took software engineering classes or hardcore CS classes?

  • College Courses through distance learning

    - by Matt
    I realize this isn't really a programming question, but didn't really know where to post this in the stackexchange and because I am a computer science major i thought id ask here. This is pretty unique to the programmer community since my degree is about 95% programming. I have 1 semester left, but i work full time. I would like to finish up in December, but to make things easier i like to take online classes whenever I can. So, my question is does anyone know of any colleges that offer distance learning courses for computer science? I have been searching around and found a few potential classes, but not sure yet. I would like to gather some classes and see what i can get approval for. Class I need: Only need one C SC 437 Geometric Algorithms C SC 445 Algorithms C SC 473 Automata Only need one C SC 452 Operating Systems C SC 453 Compilers/Systems Software While i only need of each of the above courses i still need to take two more electives. These also have to be upper 400 level classes. So i can take multiple in each category. Some other classes I can take are: CSC 447 - Green Computing CSC 425 - Computer Networking CSC 460 - Database Design CSC 466 - Computer Security I hoping to take one or two of these courses over the summer. If not, then online over the regular semester would be ok too. Any help in helping find these classes would be awesome. Maybe you went to a college that offered distance learning. Some of these classes may be considered to be graduate courses too. Descriptions are listed below if you need. Thanks! Descriptions Computer Security This is an introductory course covering the fundamentals of computer security. In particular, the course will cover basic concepts of computer security such as threat models and security policies, and will show how these concepts apply to specific areas such as communication security, software security, operating systems security, network security, web security, and hardware-based security. Computer Networking Theory and practice of computer networks, emphasizing the principles underlying the design of network software and the role of the communications system in distributed computing. Topics include routing, flow and congestion control, end-to-end protocols, and multicast. Database Design Functions of a database system. Data modeling and logical database design. Query languages and query optimization. Efficient data storage and access. Database access through standalone and web applications. Green Computing This course covers fundamental principles of energy management faced by designers of hardware, operating systems, and data centers. We will explore basic energy management option in individual components such as CPUs, network interfaces, hard drives, memory. We will further present the energy management policies at the operating system level that consider performance vs. energy saving tradeoffs. Finally we will consider large scale data centers where energy management is done at multiple layers from individual components in the system to shutting down entries subset of machines. We will also discuss energy generation and delivery and well as cooling issues in large data centers. Compilers/Systems Software Basic concepts of compilation and related systems software. Topics include lexical analysis, parsing, semantic analysis, code generation; assemblers, loaders, linkers; debuggers. Operating Systems Concepts of modern operating systems; concurrent processes; process synchronization and communication; resource allocation; kernels; deadlock; memory management; file systems. Algorithms Introduction to the design and analysis of algorithms: basic analysis techniques (asymptotics, sums, recurrences); basic design techniques (divide and conquer, dynamic programming, greedy, amortization); acquiring an algorithm repertoire (sorting, median finding, strong components, spanning trees, shortest paths, maximum flow, string matching); and handling intractability (approximation algorithms, branch and bound). Automata Introduction to models of computation (finite automata, pushdown automata, Turing machines), representations of languages (regular expressions, context-free grammars), and the basic hierarchy of languages (regular, context-free, decidable, and undecidable languages). Geometric Algorithms The study of algorithms for geometric objects, using a computational geometry approach, with an emphasis on applications for graphics, VLSI, GIS, robotics, and sensor networks. Topics may include the representation and overlaying of maps, finding nearest neighbors, solving linear programming problems, and searching geometric databases.

  • DB Documentation Tool

    - by Hisham El-bereky
     Recently I have uploaded new project to codeplex site, DbDocument or DbDoc project is a helper tool used side by side with MS SQL server management studio tool, you can design your DB Tables in visualized way through Diagrams and then use “DbDoc” tool to generate design document in MS Word format, the generated file can be used in design review process or as history reference, the tool facilitate and reduce the time of writing DB structure documentthe current version is not so sophisticated which is intend to generate word document in table format with all tables in DB illustrating its structure and constraints, but for now it seems to be good.   For more details check DbDoc document or go immediately to DbDoc home page http://dbdocument.codeplex.com/

  • How does TDD address interaction between objects?

    - by Gigi
    TDD proponents claim that it results in better design and decoupled objects. I can understand that writing tests first enforces the use of things like dependency injection, resulting in loosely coupled objects. However, TDD is based on unit tests - which test individual methods and not the integration between objects. And yet, TDD expects design to evolve from the tests themselves. So how can TDD possibly result in a better design at the integration (i.e. inter-object) level when the granularity it addresses is finer than that (individual methods)?

  • Thought Oracle Usability Advisory Board Was Stuffy? Wrong. Justification for Attending OUAB: ROI

    - by ultan o'broin
    Looking for reasons tell your boss why your organization needs to join the Oracle Usability Advisory Board or why you need approval to attend one of its meetings (see the requirements)? Try phrases such as "Continued Return on Investment (ROI)", "Increased Productivity" or "Happy Workers". With OUAB your participation is about realizing and sustaining ROI across the entire applications life-cycle from input to designs to implementation choices and integration, usage and performance and on measuring and improving the onboarding and support experience. If you think this is a boring meeting of middle-aged people sitting around moaning about customizing desktop forms and why the BlackBerry is here to stay, think again! How about this for a rich agenda, all designed to engage the audience in a thought-provoking and feedback-illiciting day of swirling interactions, contextual usage, global delivery, mobility, consumerizationm, gamification and tailoring your implementation to reflect real users doing real work in real environments.  Foldable, rollable ereader devices provide a newspaper-like UK for electronic news. Or a way to wrap silicon chips, perhaps. Explored at the OUAB Europe Meeting (photograph from Terrace Restaurant in TVP. Nom.) At the 7 December 2012 OUAB Europe meeting in Oracle Thames Valley Park, UK, Oracle partners and customers stepped up to the mic and PPT decks with a range of facts and examples to astound any UX conference C-level sceptic. Over the course of the day we covered much ground, but it was all related in a contextual, flexibile, simplication, engagement way aout delivering results for business: that means solving problems. This means being about the user and their tasks and how to make design and technology transforms work into a productive activity that users and bean counters will be excited by. The sessions really gelled for me: 1. Mobile design patterns and the powerful propositions for customers and partners offered by using the design guidance with Oracle ADF Mobile. Customers' and partners' developers existing ADF developers are now productive, efficient ADF Mobile developers applying proven UX guidance using ADF Mobile components and other Oracle Fusion Middleware in the development toolkit. You can find the Mobile UX Design Patterns and Guidance on Building Mobile Apps on OTN. 2. Oracle Voice and Apps. How this medium offers so much potentual in the enterprise and offers a window in Fusion Apps cloud webservices, Oracle RightNow NLP and Nuance technology. Exciting stuff, demoed live on a mobile phone. Stay tuned for more features and modalities and how you can tailor your own apps experience.  3. Oracle RightNow Natural Language Processing (NLP) Virtual Assistant technology (Ella): how contextual intervention and learning from users sessions delivers a great personalized UX for users interacting with Ella, a fifth generation VA to solve problems and seek knowledge. 4. BYOD Keynote: A balanced keynote address contrasting Fujitsu's explaining of the conceprt, challenges, and trends and setting the expectation that BYOD must be embraced in a flexible way,  with the resolute, crafted high security enterprise requirements that nuancing the BYOD concept and proposals with the realities of their world of water tight information and device sharing policies. Fascinating stuff, as well providing anecdotes to make us thing about out own DYOD Deployments. One size does not fit all. 5. Icon Cultural Surveys Results and Insights Arising: Ever wondered about the cultural appropriateness of icons used in software UIs and how these icons assessed for global use? Or considered that social media "Like" icons might be  unacceptable hand gestures in culture or enterprise? Or do the old world icons like Save floppy disk icons still find acceptable? Well the survey results told you. Challenges must be tested, over time, and context of use is critical now, including external factors such as the internet and social media adoption. Indeed the fears about global rejection of the face and hand icons was not borne out, and some of the more anachronistic icons (checkbooks, microphones, real-to-real tape decks, 3.5" floppies for "save") have become accepted metaphors for current actions. More importantly the findings brought into focus the reason for OUAB - engage with and illicit feedback though working groups before we build anything. 6. EReaders and Oracle iBook: What is the uptake and trends of ereaders? And how about a demo of an iBook with enterprise apps content?  Well received by the audience, the session included a live running poll of ereader usage. 7. Gamification Design Jam: Fun, hands on event for teams of Oracle staff, partners and customers, actually building gamified flows, a practice that can be applied right away by customers and partners.  8. UX Direct: A new offering of usability best practices, coming to an external website for you in 2013. FInd a real user, observe their tasks, design and approve, build and measure. Simple stuff to improve apps implications no end. 9. FUSE (an internal term only, basically Fusion Simplified Experience): demo of the new Face of Fusion Applications: inherently mobile, simple to use, social, personalizable and FAST, three great demos from the HCM, CRM and ICT world on how these UX designs can be used in different ways. So, a powerful breadth and depth of UX solutions and opporunities for customers and partners to engage with and explore how they can make their users happy and benefit their business reaping continued ROI from those apps investments.

  • What are some good resources for learning about file systems? [closed]

    - by Daniel
    I'd like to learn about file system design at a very detailed level. I'm currently in a graduate level operating systems course, and we're currently going over file systems. We mostly discuss papers and such, but our semester long project is to implement a log-structured file system using fuse and a virtual disk. Are there any good books that focus heavily on file system design and implementation? I have some conceptual clouding on things that seem very basic such as "when we say that an inode has pointers to blocks, do we mean anything besides the inode keeping track of block numbers? Is there any other format for 'disk pointers'?" I'm actually looking at file system design to start my career, so I'm probably going to try to implement a more traditional file system with fuse and our virtual disk format after this course is over.

  • Penny auction concept and how the timer works

    - by madi
    I am creating a penny auction site using PHP yii framework. The main consideration of the system is to update the database records of all active auctions (max 15 auctions) with the current ticker timer. I am seeking for advice on how i should design the system where every auction item will have a its own countdown timer stored in the database and when someone bids the auction item, the counter resets to 2 min. Every users who are connected to the system should see the same countdown timer for that particular auction. I am little confused on how i should design the system. Will there be a performance issue when there are frequent updates to the database (Mysql) where 15 active auctions are updated every seconds, the countdown timer decreases by a second in the database table for the particular auction. Schema Sample for auction_lots: Auction_id,startdatetime,counter_timer,status I am seeking for advice on how I should design this. Please help. Thank you!

  • New Office 2010 theme added for creating current UIs

    - by Webgui
    Visual WebGui offers its developers a set of out-of-the-box themes which they can easily apply to their applications. This allows developers to focus on the development and business logic rather than dealing with UI design missions. However, design tools and customization freedom are available for those who need to customize current themes or create their own custom theme. As part of the constant updates and enhancements to Visual WebGui and its developer CompanionKit a new available theme was added last week. The new theme applies the latest Microsoft UI - Office 2010 to Visual WebGui and allows developers and/or end users (of 6.4.0 and above) to switch their Web applications UI to the successful design of Office 2010. After the latest update the new theme is integrated into the Visual WebGui Developers CompanionKit which now matches Visual WebGui 6.4.0 Release version's infrastructure. The update also includes several enhancements to existing controls and features and the addition of some new ones. Go to the CompanionKit

  • Process development lifecycle in Oracle BPM 11g

    - by mesriniv
       Oracle BPM 11g platform provides two modeling tools tailored to different audience. The BPM Process Composer component is a web-based, role-driven, collaborative platform for discovery, design and documentation of business processes aimed at business audience. It empowers the business user to participate in the definition, feedback and design of business processes. The other modeling tool is Oracle BPM Studio that runs in the JDeveloper IDE .  Irrespective of the tool used, same BPMN and related artifacts are authored - that is , this is not import/export but just multiple tools working with same assets. In addition to BPMN 2.0, both tools provides editors for process data, organizational roles, human tasks (including assignment and user interface), business rules. The Oracle BPM design-time repository (Oracle Metadata Services Repository) is the glue that facilitates shared work environment across multiple BPM Composer and Studio clients.This document explains how to create snapshots and versions of your BPM projects and captures best practices for shared process development lifecycle. http://java.net/projects/oraclebpmsuite11g/downloads/directory/Samples/bpm-122-processdevelopment-lifecycle

  • How to survive if you can only do things your way as a programmer?

    - by niceguyjava
    I hate hibernate, I hate spring and I am the kind of programmer who likes to do things his way. I hate micro-management and other people making decisions for me about what framework I should use, what patterns I should apply (hate patterns too) and what architecture I should design. I consider myself a successful programmer and have a descent financial situation due to my performance in past jobs, but I just can't take the standard Java jobs out there. I really love to design things from scratch and hate when I have to maintain other people's bad code, design and architecture, which is the majority you find out there for sure. Does anybody relate to that? What do you guys recommend me? Open up my on company, do consulting, or just keep looking hard until I find a job that suits my preferences, as hard as this may look like with all the hibernate and spring crap out there?

  • When JDeveloper IDE doesn't render the visual editor

    - by Frank Nimphius
    Though with Oracle JDeveloper 11g the problem of the IDE not rendering JSF pages properly in the visual editor has become rare, there always is a way for the creative to break IDE functionality. A possible reason for the visual editor in JDeveloper to break is a failed dependency reference, which often is in a custom JSF PhaseListener configured in the faces-config.xml file. To avoid this from happening, surround the code in your PhaseListener class with the following statement (for example in the afterPhase method) public void afterPhase(PhaseEvent phaseEvent) {   if(!ADFContext.getCurrent().isDesigntime()){ ... listener code here ... } } The reason why the visual editor in Oracle JDeveloper fails rendering the WYSIWYG view has to do with how the live preview is created. To produce the visual display of a view, JDeveloper actually runs the ADF Faces view in JSF, which then also invokes defined PhaseListeners. With the code above, you check whether the PhaseListener code is executed at runtime or design time.If it is executed in design time, you ignore all calls to external resources that are not available at design time.

  • In what order do people build websites?

    - by Corey
    For a website, you need to have an idea, you need to have a design and you need to have data, events and output, right? Whether it be a blog, web app, Q&A site, search engine... Anyway, that is only slightly related to my question. My question is, when designing a website, providing I know the purpose, what should I start with? Should I start with the CSS, design and look&feel using dummy data first, or should I program in the logic, events and output, and style it later? What is the design process of most websites that are built from the ground up?

  • Hidden text and links appearing just on click for SEO?

    - by CamSpy
    I am working on a site that has neat clean/minimalistic design/layout. Menu items are "hidden" behind an icon, to see them, users need to click on that icon to get a javascript toggled overlay with the list of menu items. Then there are blocks with photos and users need to click on a small icon/button on each of them to get a block of text shown for each of the photo. While I don't like such "design" myself, making me click lots of time just to read, I also think that for SEO purpose this model is really wrong. Is such model bad for SEO? Are there ways to keep design like this but have "safe" methods of displaying text content on click that will not hurt SEO?

  • Testability &amp; Entity Framework 4.0

    This white paper describes and demonstrates how to write testable code with the ADO.NET Entity Framework 4.0 and Visual Studio 2010. This paper does not try to focus on a specific testing methodology, like test-driven design (TDD) or behavior-driven design (BDD). Instead this paper will focus on how to write code that uses the ADO.NET Entity Framework yet remains easy to isolate and test in an automated fashion. Well look at common design patterns that facilitate testing in data access scenarios...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Jquery datepicker popup not closing on select date in IE8

    - by Notorious2tall
    I've got a web form with a start date field. I've tied a jquery datepicker to the txt field. Now when I choose a date in FF, the selected date is populated in the text box and the calendar popup closes. However when I do the same thing in IE8, the selected date is populated in the text box but the popup remains open. I've also noticed that a script error is generated as soon as I select a date in the popup calendar. I'm using jquery 1.3.2, jquery-ui 1.7.2, and .NET 3.5. Here's an example of my code: <script type="text/javascript"> $(document).ready(function() { $("#<%=txtStartDate.ClientID%>").datepicker({ changeMonth: true, changeYear: true, showButtonPanel: true, showOn: 'button', buttonImage: '/_layouts/images/CALENDAR.GIF', buttonImageOnly: true }); }); </script> <div id="stylized"> <asp:ValidationSummary ID="vs" runat="server" CssClass="messages-error" HeaderText=" Action required before the form can be submitted." ForeColor="" ValidationGroup="sh" /> <div class="formrow"> <div class="ms-formlabel formlabel"> <asp:Label ID="lblStartDate" runat="server" CssClass="ms-standardheader" AssociatedControlID="txtStartDate">Start Date:</asp:Label> </div> <div class="ms-formbody formfield"> <asp:RequiredFieldValidator ID="reqStartDate" runat="server" ControlToValidate="txtStartDate" ErrorMessage="Start Date is a required field." Text="*" Display="Dynamic" ValidationGroup="sh"></asp:RequiredFieldValidator> <asp:CompareValidator ID="cvStartDate" runat="server" ControlToValidate="txtStartDate" ErrorMessage="Date must be in the format MM/DD/YYYY" Text="*" Display="Dynamic" ValidationGroup="sh" Operator="DataTypeCheck" Type="Date"></asp:CompareValidator> <asp:TextBox ID="txtStartDate" runat="server"></asp:TextBox> <span class="formMessage">ex. MM/DD/YYYY</span> </div> </div> <div id="buttonrow"> <asp:Button ID="btnSubmit" runat="server" Text="Submit" CssClass="ms-ButtonHeightWidth" OnClick="Submit_Click" ValidationGroup="sh" /> <asp:Button ID="btnCancel" runat="server" Text="Cancel" CssClass="ms-ButtonHeightWidth" OnClick="Cancel_Click" CausesValidation="false" /> </div> </div> Here's the script error I get in IE when I select the date: 'length' is null or not an object WebResource.axd Here's the code where the error is being thrown from: function ValidatorOnChange(event) { if (!event) { event = window.event; } Page_InvalidControlToBeFocused = null; var targetedControl; if ((typeof(event.srcElement) != "undefined") && (event.srcElement != null)) { targetedControl = event.srcElement; } else { targetedControl = event.target; } var vals; if (typeof(targetedControl.Validators) != "undefined") { vals = targetedControl.Validators; } else { if (targetedControl.tagName.toLowerCase() == "label") { targetedControl = document.getElementById(targetedControl.htmlFor); vals = targetedControl.Validators; } } var i; for (i = 0; i < vals.length; i++) { ValidatorValidate(vals[i], null, event); } ValidatorUpdateIsValid(); } It happens on the .length in the for loop at the end. Vals is null and isn't found in the previous if/else. I've stepped through the javascript and if (typeof(targetedControl.Validators) != "undefined") returns false and then if (targetedControl.tagName.toLowerCase() == "label") returns false too. Thus the length is null or not an object error. Now I'm not sure if the datepicker popup not closing in IE and the script error in the WebResources.axd file are related errors, but I'm leaning that way. Can anyone tell me why the popup isn't closing?

  • jqGrid: sort by index

    - by David__
    I am having trouble getting a column to sort by an index other than the 'name' value. In this case I am trying to sort the aggregation type column (values are days of the week) by the week order, rather than alphanumeric order. To do this I added an index column ('Aggregation type-index') that has the days of week an integers. However with this configuration, it fails to sort that column by index or name. Can someone point me the err in my ways? I posted all the js and css that is on the page, because I am also having two other issues, that if you notice the problem great, otherwise I'll keep hunting. I want to be able to enable the column reodering and be able to resize the grid (Both shown at http://trirand.com/blog/jqgrid/jqgrid.html under the new in 3.6 tab).

  • ListView items not responding to tap

    - by Justin Williams
    I'm just getting my feet wet with Android and have built a UI that contains a TabHost with three tabs. Each tab is powered by its own Activity. The first Tab contains a listview with a prepopulated set of rows and is built from a custom ArrayAdapter. The problem I'm running into is that none of the ListView rows are tappable. In other words, when I tap on them there is no orange selection. If I use the scroll ball on my Nexus One it will select, but any touch gestures don't seem to be responding. All the UI is being handled using XML files with a main.xml housing the TabHost - LinearLayout - TabWidget/FrameLayout and a nearby_activity.xml file containing my ListView UI <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:id="@+id/android:empty" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="@string/nearby_no_events" /> <ListView android:id="@android:id/list" android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1.0" android:choiceMode="multipleChoice" android:divider="#d9d9d9" android:dividerHeight="1px" android:cacheColorHint="#eee" /> </LinearLayout> And the relevant code from my Activity that is set to show in the selected tab. public class NearbyActivity extends ListActivity { private ArrayList<Event> m_events = null; private EventAdapter m_adapter = null; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.nearby_activity); getEvents(); this.m_adapter = new EventAdapter(this, R.layout.eventrow, m_events); setListAdapter(this.m_adapter); } private void getEvents() { m_events = new ArrayList<Event>(); for (int i = 0; i < 100 ; i++) { Event e = new Event(); e.setEventName("Event " + i); e.setVenueName("Staples Center"); e.setStartDate(new Date()); m_events.add(e); } } private class EventAdapter extends ArrayAdapter<Event> { private ArrayList<Event> items; public EventAdapter(Context context, int textViewResourceId, ArrayList<Event> items) { super(context, textViewResourceId, items); this.items = items; } @Override public View getView (int position, View convertView, ViewGroup parent) { View v = convertView; if (v == null) { LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE); v = vi.inflate(R.layout.eventrow, null); } Event e = items.get(position); if (e != null) { TextView nameText = (TextView)v.findViewById(R.id.eventName); TextView venueNameText = (TextView)v.findViewById(R.id.venueName); if (nameText != null) { nameText.setText(e.getEventName()); } if(venueNameText != null) { venueNameText.setText(e.getVenueName()); } } return v; } } } My listview row's are populated by an XML file as well. <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="?android:attr/listPreferredItemHeight" android:orientation="vertical" android:padding="4dip"> <TextView android:id="@+id/eventName" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:inputType="text" android:singleLine="true" android:ellipsize="marquee" android:textSize="18sp" android:textColor="#000" /> <TextView android:id="@+id/venueName" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@id/eventName" android:layout_alignParentBottom="true" android:layout_marginRight="55dip" android:singleLine="true" android:ellipsize="end" android:scrollHorizontally="true" android:textSize="13sp" android:textColor="#313131" android:layout_alignWithParentIfMissing="true" android:gravity="center_vertical" /> </RelativeLayout> Thanks for any help you can offer.

  • Actionscript multiple file upload, with parameter passing is not working

    - by Metropolis
    Hey everyone, First off, I am very bad at flash/actionscript, it is not my main programming language. I have created my own file upload flash app that has been working great for me up until this point. It uses PHP to upload the files and sends back a status message which gets displayed in a status box to the user. Now I have run into a situation where I need the HTML to pass a parameter to the Actionscript, and then to the PHP file using POST. I have tried to set this up just like adobe has it on http://livedocs.adobe.com/flex/3/html/help.html?content=17_Networking_and_communications_7.html without success. Here is my Actionscript code import fl.controls.TextArea; //Set filters var imageTypes:FileFilter = new FileFilter("Images (*.jpg, *.jpeg, *.gif, *.png)", "*.jpg; *.jpeg; *.gif; *.png"); var textTypes:FileFilter = new FileFilter("Documents (*.txt, *.rtf, *.pdf, *.doc)", "*.txt; *.rtf; *.pdf; *.doc"); var allTypes:Array = new Array(textTypes, imageTypes); var fileRefList:FileReferenceList = new FileReferenceList(); //Add event listeners for its various fileRefList functions below upload_buttn.addEventListener(MouseEvent.CLICK, browseBox); fileRefList.addEventListener(Event.SELECT, selectHandler); function browseBox(event:MouseEvent):void { fileRefList.browse(allTypes); } function selectHandler(event:Event):void { var phpRequest:URLRequest = new URLRequest("ajax/upload.ajax.php"); var flashVars:URLVariables = objectToURLVariables(this.root.loaderInfo); phpRequest.method = URLRequestMethod.POST; phpRequest.data = flashVars; var file:FileReference; var files:FileReferenceList = FileReferenceList(event.target); var selectedFileArray:Array = files.fileList; var listener:Object = new Object(); for (var i:uint = 0; i < selectedFileArray.length; i++) { file = FileReference(selectedFileArray[i]); try { file.addEventListener(DataEvent.UPLOAD_COMPLETE_DATA, phpResponse); file.upload(phpRequest); } catch (error:Error) { status_txt.text = file.name + " Was not uploaded correctly (" + error.message + ")"; } } } function phpResponse(event:DataEvent):void { var file:FileReference = FileReference(event.target); status_txt.htmlText += event.data; } function objectToURLVariables(parameters:Object):URLVariables { var paramsToSend:URLVariables = new URLVariables(); for(var i:String in parameters) { if(i!=null) { if(parameters[i] is Array) paramsToSend[i] = parameters[i]; else paramsToSend[i] = parameters[i].toString(); } } return paramsToSend; } The flashVars variable is the one that should contain the values from the HTML file. But whenever I run the program and output the variables in the PHP file I receive the following. //Using this command on the PHP page print_r($_POST); //I get this for output Array ( [Filename] => testfile.txt [Upload] => Submit Query ) Its almost like the parameters are getting over written or are just not working at all. Thanks for any help, Metropolis

  • receiving error #1009 in flash cs4 actionscript3

    - by Leah
    I'm having a weird issue where my buttons will work initially and direct me to an appropriate page, but when i go back to that page and try to use the buttons the roll-overs work but none of the buttons direct to a different page. This is the actionscript on the initial page with the buttons. If I choose any of these buttons they work. For example the profile_btn will take me to the go_to_page" stop(); import flash.events.MouseEvent; //button instancese listed below profile_btn.addEventListener(MouseEvent.CLICK, aClick); function aClick(event:MouseEvent):void{ gotoAndPlay("go_to_page"); } color_btn.addEventListener(MouseEvent.CLICK, cClick); function cClick(event:MouseEvent):void{ gotoAndPlay("color_page"); } drawing_btn.addEventListener(MouseEvent.CLICK, dClick); function dClick(event:MouseEvent):void{ gotoAndPlay("drawing_page"); } letsgo_btn.addEventListener(MouseEvent.CLICK, fClick); function fClick(event:MouseEvent):void{ gotoAndPlay("home_page"); } //go to flash fish animation digital_btn.addEventListener(MouseEvent.CLICK,onMouseClick2); function onMouseClick2(e:MouseEvent):void { var request:URLRequest=new URLRequest("aquarium2.swf"); navigateToURL(request,"blank");} //go to resume document resume_btn.addEventListener(MouseEvent.CLICK,onMouseClick3); function onMouseClick3(e:MouseEvent):void { var request:URLRequest=new URLRequest("LeahHonseyResume.pdf"); navigateToURL(request,"blank"); once at the go_to_page, it plays through a motion tween and ends up at the profile_page. from this page, there is a home_btn. Here is the actionscript for the profile_page. stop(); home_btn.addEventListener(MouseEvent.CLICK, gClick); function gClick(event:MouseEvent):void{ gotoAndPlay("return_frame"); } But when I click on the home_btn I get an output: TypeError: Error #1009: Cannot access a property or method of a null object reference. at flash7_fla::MainTimeline/frame38() It does take me to the correct page, but none of the button then on this page are working. the actionscript for the return_frame page is: stop(); import flash.events.MouseEvent; //button instances listed below profile_btn.addEventListener(MouseEvent.CLICK, hClick); function hClick(event:MouseEvent):void{ gotoAndPlay("profile_page"); } color_btn.addEventListener(MouseEvent.CLICK, iClick); function iClick(event:MouseEvent):void{ gotoAndPlay("color_page"); } drawing_btn.addEventListener(MouseEvent.CLICK, jClick); function jClick(event:MouseEvent):void{ gotoAndPlay("drawing_page"); } letsgo_btn.addEventListener(MouseEvent.CLICK, kClick); function kClick(event:MouseEvent):void{ gotoAndPlay("home_page"); } //go to flash fish animation digital_btn.addEventListener(MouseEvent.CLICK,onMouseClick4); function onMouseClick4(e:MouseEvent):void { var request:URLRequest=new URLRequest("aquarium2.swf"); navigateToURL(request,"blank");} //go to resume document resume_btn.addEventListener(MouseEvent.CLICK,onMouseClick5); function onMouseClick5(e:MouseEvent):void { var request:URLRequest=new URLRequest("LeahHonseyResume.pdf"); navigateToURL(request,"blank");} Can anyone help me figure out why this script is not working? Thank you. I am a beginner flash user, and am trying to build my portfolio site for a homework assignment on Monday. Leah

  • Flex/PHP/XML data issue

    - by reado
    I have built a simple application in Flex. When the application loads, a GET request is made to the xmlService.php file with parameters "fetchData=letters". This tells the PHP to return the XML code. In Flex Debug I can see the XML data being sent by the PHP to the flex client. What I need it to do is populate the first drop down box (id="letter") with this data, however nothing is being received by Flex. I added an Alert.show() to check what was being returned but when the application runs, the alert is blank. Can anyone help? Thanks in advance.

  • jquery scope issue

    - by matthewb
    I am having issue with the following: I can't seem to keep the link I am selecting in each repeated item. The word "this" is getting lost. the Var event_id works for each element, but the var $something is undefined? Why is that, Ideally I wanted to do a switch statement but same issue, can't seem to get it to know what link I click and the elements around it to do the action. Updated Full Function: function rsvp (selector,function_url) { $(selector).livequery('click',function(){ var $select = $(selector).attr('rel'); var $event_id= $(this).parents('ul.event-options').attr('rel'); if ($select == "attending") { $(this).closest('span.rsvp-status').html("I'm Attending &ndash; <a href='javascript:;' class='remove' rel='remove'>Remove</a>"); var $something = $(this).parents('ul.event-options').attr('rel'); alert($something); } if ($select == "remove") { $(this).closest('span.rsvp-status').html("Not Attending &ndash; <a href='javascript:;' class='rsvp' rel='attending'>RSVP?</a>"); } if ($select == "interested") { $(this).closest('li').addClass('interested'); $(this).closest('li').removeClass('not-interested'); $(this).closest('li').html("You're Interested"); } $.ajax({ type: "POST", url: "/events/set_member/"+function_url, data: "event_id="+$event_id, beforeSend: function() { $("<span class='notice'>Updating...</span>").prependTo('body'); }, complete: function() { $('span.notice').fadeOut(500); } }); }); } rsvp ('a.rsvp','rsvp'); rsvp ('a.interests','interested'); rsvp ('a.remove','remove'); HTML <ul class="event-options" rel="<?=$event['event_id']?>"> <?php if($event['rsvp_total'] > 0) { ?> <!-- Show Only When Count is Greater than 0 --> <li class="group"><span class="total"><?= $event['rsvp_total']?></span>Interested </li> <?php } ?> <li class="rsvp"><span class="rsvp-status"> Not Attending &ndash; <a href="javascript:;" class="rsvp" rel="attending">RSVP?</a></span></li> <li class="not-interested"> <a href="javascript:;" class="interests" rel="interested"> Interested? </a> </li> <li class="place"><span><a href="<?=$place_path.$event['place_id']?>"><?=$event['place_name']?></a></span></li> <li class="share" rel="<?=$event['event_name']?>"> <a class="sharethis"></a> </li> </ul>

  • Flash As3 Loader Problem

    - by Hadar
    Hi iam trying to load a few external jpegs in As3. It works fine locally in Flash, but it dosen't work at all ion my server. My app also loads a youtube video simultaneously. function drawResult(index,videoID,song_title,thumbnail:String=null) { var theClip:resultRowClip=new resultRowClip (); _clip.addChild(theClip); myArray[index] = new Array(videoID,theClip); theClip.y=0+(43*(index-1)); theClip.rowText.text = song_title; theClip.rowBack.visible = false; if (thumbnail != ""){ theClip.tHolder.visible=true; loadImage(thumbnail,index); } } function loadImage(url:String,index):void { //this.myClip.myText.text += "load image"; // Set properties on my Loader object var imageLoader:Loader = new Loader(); imageLoader.load(new URLRequest(url)); imageLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, function (evt:Event){imageLoaded(evt,index)}); } function imageLoaded(evt,id):void { //this.myClip.myText.text += "id : evt : " + evt.status; // Load Image var image:Bitmap = new Bitmap(evt.target.content.bitmapData); myArray[id][1].tHolder.addChild(image); myArray[id][1].tHolder.width=myArray[id][1].tHolder.width*0.35; myArray[id][1].tHolder.height=myArray[id][1].tHolder.height*0.35; } Does anyone knows what the problem is ? ** I added two Evenet listeners from io Error : imageLoader.addEventListener(IOErrorEvent.IO_ERROR,ioErrorHandler); imageLoader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR,ioErrorHandler); This is the function for handling the errors : private function ioErrorHandler(event:IOErrorEvent):void { this.myClip.myText.text +=("ioErrorHandler: " + event); } anyway, I got no errors... I also tried to move the listeners before imageLoader.load but it's still the same...no errors and no data loaded.. I change my code to patrikS suggestion : function loadImage(url:String,index):void { //this.myClip.myText.text += "load image"; // Set properties on my Loader object //if (index != 1) return; var imageLoader:Loader = new Loader(); imageLoader.name = index.toString(); //myArray[index][1].addChild(imageLoader); //imageLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, function (evt:Event){imageLoaded(evt,index)}); imageLoader.contentLoaderInfo.addEventListener(Event.COMPLETE,completeHandler); imageLoader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR,ioErrorHandler); imageLoader.load(new URLRequest(url)); } My current completeHandler function(tnx patrikS ) : private function completeHandler(evt:Event):void{ //this.myClip.myText.text += "id : evt : " + evt.status; // Load Image trace("evt target loader name : "+ evt.target.loader.name ); evt.target.removeEventListener(Event.COMPLETE, completeHandler ); var image:Bitmap = new Bitmap(evt.target.content.bitmapData); myArray[evt.target.loader.name][1].tHolder.addChild(image); myArray[evt.target.loader.name][1].tHolder.width=myArray[evt.target.loader.name][1].tHolder.width*0.35; myArray[evt.target.loader.name][1].tHolder.height=myArray[evt.target.loader.name][1].tHolder.height*0.35; //trace (hadar.y + "Y / X" + hadar.x); } It still work only on flash IDE and dosent work on any browser...
