  • Loading multiple embedded flash apps onto an HTML page- problem with ordering

    - by shudson250
    We need to load an embedded version of a site written in Flash, and not originally designed to load multiple instances of itself, on a HTML page. The specific issue is how to get them to load in order when embedded, given that they are all being opened by the same instance of the flash player. It's a complicated mapping application, and at the moment, the maps and data get intermixed as the session variables are overwritten by another instance starting to load before the previous one has finished. We need a way to have them load sequentially, one finishing before another starts to load. The most we can specify in the URL is an &order=1 or similar. We have PHP and SQL on the backend. Edit: The embedded versions are being loaded in an iFrame of a parent site. One php file loads one swf, as many times as the parent site desires.

  • Anyone been successful changing their career without having to start over from scratch?

    - by Awaken
    I posted a similar question on careeroverflow, but stackoverflow is just way more active and has way more users, so hopefully someone out there can help answer. I am currently an embedded developer in the defense/aerospace world for a big company. While I like the benefits and the pay, it just isn't keeping me happy. The Paul Graham article: How To Do What You Love really struck home. The problem I face are my golden handcuffs. When I look at jobs out there, they all want 5+ years experience in that language with expertise in framework/tool/server A,B,C, etc... I have worked in C and C++ on the job (in a real-time embedded environment) with some small things in C# and Java. I'm learning Ruby now to expand my knowledge, but I don't consider myself an expert in anything right now. I'd love to work on desktop applications or web apps. Is it possible for someone like me to make the switch without going back to the start line? I'd love to leave the huge bureaucracy and work with some great developers. I'd be willing to work late and take a modest pay cut, but that isn't so clear just from a resume. For those that have altered their career path, how did you do it? For those people who are in charge of hiring, what can I do to help myself?

  • Internet of Things (IoT) Thanksgiving Special: Turkey Tweeter (Part 1)

    - by hinkmond
    It's time for the Internet of Things (ioT) Thanksgiving Special. This time we are going to work on a special Do-It-Yourself project to create an Internet of Things temperature probe to connect your Turkey Day turkey to the Internet by writing a Thanksgiving Day Java Embedded app for your Raspberry Pi which will send out tweets as it cooks in your oven. If you're vegetarian, don't worry, you can follow along and just run the simulation of the Turkey Tweeter, or better yet, try a tofu version of the Turkey Tweeter. Here is the parts list: 1 Vernier Go!Temp USB Temperature Probe 1 Uncooked Turkey 1 Raspberry Pi (not Pumpkin Pie) 1 Roll thermal reflective tape You can buy the Vernier Go!Temp USB Temperature Probe for $39 from here: http://www.vernier.com/products/sensors/temperature-sensors/go-temp/. And, you can get the thermal reflective tape from any auto parts store. (Don't tell them what you need it for. Say it's for rebuilding your V-8 engine in your Dodge Hemi. Avoids the need for a long explanation and sounds cooler...) The uncooked turkey can be found in your neighborhood grocery store. But, if you're making a vegetarian Tofurkey, you're on your own... The Java Embedded app will be the same, though (Java is vegan). So, grab all your parts and come back here for the next part of this project... Hinkmond

  • What Computing/Programming Qualifications should I aspire for

    - by indevel
    I am a computing science post graduate in my first job from after my degree. During my 12 month review my boss posed the question "What can we do for you in terms of progressing your career?". This got me thinking, after university I hadn't really thought about what other qualifications were available. So this is my question, what courses/qualifications should I be looking to do. Which are highly regarded and which would be really useful to complete. I've searched Google it but all I see is a jumble of courses with no idea of the credibility of each. Any help is much appreciated. I'm traditionally a systems architect, but with this job I've turned to more embedded work so Id like to edge towards electronics, embedded programming, real time OS to help with my work also it would be more likely to be accepted if it was related to my job. Finally UK based courses/ qualifications are a must as travel is probably out of the question. Help me grow as a programmer.

  • WPF Control Toolkits Comparison for LOB Apps

    In preparation for a new WPF project Ive been researching options for WPF Control toolkits.  While we want a lot of the benefits of WPF, the application is a fairly typical line of business application (LOB).  So were not focused on things like media and animations, but instead a simple, solid, intuitive, and modern user interface that allows for well architected separation of business logic and presentation layers. While WPF is mature, it hasnt lived the long life that Winforms has yet, so there is still a lot of room for third party and community control toolkits to fill the gaps between the controls that ship with the Framework.  There are two such gaps I was concerned about.  As this is an LOB app, we have needs for presenting lots of data and not surprisingly much of it is in grid format with the need for high performance, grouping, inline editing, aggregation, printing and exporting and things that weve been doing with LOB apps for a long time.  In addition we want a dashboard style for the UI in which the user can rearrange and shrink and grow tiles that house the content and functionality.  From a cost perspective, building these types of well performing controls from scratch doesnt make sense.  So I evaluated what you get from the .NET Framework along with a few different options for control toolkits.  I tried to be fairly thorough, but know that this isnt a detailed benchmarking comparison or intense evaluation.  Its just meant to be a feature set comparison to be used when thinking about building an LOB app in WPF.  I tried to list important feature differences and notes based on my experience with the trial versions and what I found in documentation and reference materials and samples.  Ive also listed the importance of the controls based on how I think they are needed in LOB apps.  There are several toolkits available, but given I dont have unlimited time, I picked just a few.  Maybe Ill add on more later.  The toolkits I compared are: Teleriks RadControls for WPF since I had heard some good things about Telerik Infragistics NetAdvantage WPF since both I and the customer have some experience with the vendors tools WPF Toolkit on codeplex since many of my colleagues have used it Blacklight codeplex project which had WPF support for the Tile View control  (with Release 4.3 WPF is not going to be supported in favor of focusing only on SilverLight controls, so I dropped that from the comparison) Click Here to Download the WPF Control Toolkits Comparison Hopefully this helps someone out there.  Feel free to post a comment on your experiences or if you think something I listed is incorrect or missing.  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.

  • AJAX Control Toolkit - Incompatibility with HTMLEditor and UpdatePanel

    - by Guilherme Cardoso
    Unfortunately HTMLEditor component of AJAX Control Toolkit is not compatible with the UpdatePanel. The problem is when we use accents with the Mozilla Firefox browser and HTMLEditor is inside an UpdatePanel. Letters that contain accents are left with an unknown character (so is stored in the database or even returned a PostBack). Can be tested using Mozilla Firefox on the site of the ASP.NET AJAX Control Toolkit.  Write a word with accents and go to "Submit Content": http://www.asp.net/AJAX/AjaxControlToolkit/Samples/HTMLEditor/HTMLEditor.aspx As an alternative to this problem there are multiple component Rich Text Editors, some using jQuery and others not. Queneeshas provided us a list of 10 components that can be viewed here: http://www.queness.com/post/212/10-jquery-and-non-jquery-javascript-rich-text-editors Hopefully next release of the AJAX Control Toolkit, this inconsistency and others (like the ModalPopup Extender that already referenced in my blog) are resolved once and for all. This is because there are more updated versions prior to that do not have these problems, and with the passing of time some parts were coming into conflict. If you know of any alternative or want to know at this problem, you can visit the topic I created the section of the AJAX Control Toolkit in ASP.NET forum: http://forums.asp.net/p/1548141/3848763.aspx

  • How to Access the Control Panel in Windows 8

    - by Matthew Klein
    With the old Windows Start menu, you could add the Control Panel as a menu or a drop-down list. With Windows 8, you can pin the Control Panel to the Start Screen and taskbar but first you need to know where it is. One of the chief complaints about Windows 8 (or any new version of Microsoft’s operating system) is “where did such-and-such go?” With Windows 8, when MS removed the Start button and Start Menu, it threw a lot of people for a loop. Because the Start Menu was like an old familiar hang out; one of those places that no matter how it changed over the years, it was a fairly reliable place to find stuff whether it was your Documents folder, Devices, Printers, the ability to search your programs and files, and of course, the Control Panel. There are about four ways (so far) to access the Control Panel in Windows 8 Preview Release. HTG Explains: What Is RSS and How Can I Benefit From Using It?

  • Our embedded linux system won't recognize a USB Device if it is plugged in before powerup. Suggestions?

    - by Blaine
    We are developing on a small embedded device. This device us a gumstix overo board running OpenEmbedded linux. We have our development almost completely done, and have run into the strangest of bugs that we can't figure out. We have a USB Device (Spectrophotometer) that has a USB2.0 Connection and an external power supply for the light source. Typical behavior is that you plug in the power supply, then the USB connection to a host. When the usb connection is detected by the device, the device boots up and enables the light source and fan. The device is then able to be used by the host system. The problem is that if the device is plugged into the Gumstix before we turn on the Gumstix, the USB Device apparently is not probed by the system (and hence does not turn on). Under a normal situation, when the connection is initialized by plugging in the usb cable, the spectro turns itself on and becomes available to the system (this can be seen via "lsusb" typically). Neither of these things are happening. There is no device detected via "lsusb" and no dmesg errors of any kind that we can see. It is as if the device is not plugged in. The device does show up and work fine if we unplug the USB cable and plug it back in once the system is booted up. It turns on and shows up on the usb bus, and we can access it with our driver. On any other desktop or laptop, it does not matter if the host system is on or off when we plug in the spectrometer. This behavior is what I would consider to be "normal" - that the usb system is probed and initialized at boot time, and the usb devices come online. In other words, our system is fully functional as long as we plug in the usb device after the system is booted up. Unfortunately this isn't possible in our final product - everything comes on at once. Additional Info: 1) We have tried a flash drive attached to the system when the system is turned off. Booting up the system brings the flash drive online, as expected 2) There are no messages regarding the spectro or usb device (using dmesg). "lsusb" only lists the USB hubs / controllers. It is literally as if the device is not present and not plugged in. 3) We have tried a brand new image from gumstix and an older image from last year. Both images have this problem. This problem exists on all 3 gumstix devices we use. Does anyone have any suggestions? From what I can tell it isn't really possible to do a complete "reboot" of the usb system that is a complete emulation of "unplugging" and "replugging" a usb device. I feel like what is happening is that there is no initial probe on the usb bus that would trigger the usb handshaking, but this is somehow specific to the spectro. This seems to be a kernel issue or at least an issue in how the kernel is initializing the usb subsystem. I'm not really sure though. I have tried the gumstix mailing list, but there doesn't seem to be anyone who has seen this issue before. Any advice or suggestions on where to start looking would be fantastic. Thank you!

  • Updating an ADF Web Service Data Control When Service Structure or Location Change

    - by Shay Shmeltzer
    The web service data control in Oracle ADF gives you a simplified approach to consuming services in ADF applications, and now with ADF Mobile the usage of this service seems to be growing. A frequent question we get is what happens if the service that I'm consuming changes - how do I update my data control? Well, first we should mention that if you do a good design of your application before you actually code - then things like Web service method signature shouldn't change. The signature is the contract between the publisher and the consumer, and contracts shouldn't be broken. But in reality things do change during development stages, so here is how you can update both method signatures and service location with the Web service data control: After watching this video you might be tempted to not copy the WSDLs to your project - which lets you use the right click update on a data control. However there is a reason why the copy is on by default, it reduces network traffic when you are actually running your application since ADF doesn't need to go to the server to find out the service structure. So for runtime performance, you probably should keep the WSDL local.  I encourage you to further look into both the connections.xml file where your service location is saved, and the datacontrols.dcx file where its definition is kept to get an even deeper understanding of how ADF works underneath the declarative layers.

  • SQL Source Control Contest

    - by Ajarn Mark Caldwell
    If you’re a regular reader of this blog, you know that I have written several posts about how important I think it is to protect your source code, to version it, and in particular, all the aspects I like about Red Gate’s SQL Source Control product.  But for a moment, let’s take a break from my writing and I want to hear your stories.  What nightmare situation are you in, or can you imagine, where source control for your database would save the world.  Or maybe your life is not so dramatic, but you do see a challenge that, if you just had a good tool like SQL Source Control, it would go much smoother.  What’s your pain?  You have read my writings, now tell me your story, and be in the running for a free copy of SQL Source Control from Red Gate. Yes, that’s right.  Although I am just a fan of Red Gate, they have authorized me to give out a handful of licenses to blog readers who are willing to share their story by posting a comment to this blog entry.  Simply add your comment below (be sure to include a valid email address in the box that asks for that) to be entered.  The contest starts immediately and over the next few days, the best stories will win.

  • Need to tab out of ActiveX control in browser

    - by John Donoghue
    When tabbing through controls in an ActiveX control hosted in IE, once I get to the last control the tab key no longer does anything. I would like it to move the focus outside the ActiveX control to the next html control. This works fine when the ActiveX control is hosted in a WinForms app, does anybody know how to make this work in the browser? It may also be relevant that the ActiveX control is a simple wrapper around a WPF control.

  • Do You Develop Your PL/SQL Directly in the Database?

    - by thatjeffsmith
    I know this sounds like a REALLY weird question for many of you. Let me make one thing clear right away though, I am NOT talking about creating and replacing PLSQL objects directly into a production environment. Do we really need to talk about developers in production again? No, what I am talking about is a developer doing their work from start to finish in a development database. These are generally available to a development team for building the next and greatest version of your databases and database applications. And of course you are using a third party source control system, right? Last week I was in Tampa, FL presenting at the monthly Suncoast Oracle User’s Group meeting. Had a wonderful time, great questions and back-and-forth. My favorite heckler was there, @oraclenered, AKA Chet Justice.  I was in the middle of talking about how it’s better to do your PLSQL work in the Procedure Editor when Chet pipes up - Don’t do it that way, that’s wrong Just press play to edit the PLSQL directly in the database Or something along those lines. I didn’t get what the heck he was talking about. I had been showing how the Procedure Editor gives you much better feedback and support when working with PLSQL. After a few back-and-forths I got to what Chet’s main objection was, and again I’m going to paraphrase: You should develop offline in your SQL worksheet. Don’t do anything in the database until it’s done. I didn’t understand. Were developers expected to be able to internalize and mentally model the PL/SQL engine, see where their errors were, etc in these offline scripts? No, please give Chet more credit than that. What is the ideal Oracle Development Environment? If I were back in the ‘real world’ of database development, I would do all of my development outside of the ‘dev’ instance. My development process looks a little something like this: Do I have a program that already does something like this – copy and paste Has some smart person already written something like this – copy and paste Start typing in the white-screen-of-panic and bungle along until I get something that half-works Tweek, debug, test until I have fooled my subconscious into thinking that it’s ‘good’ As you might understand, I don’t want my co-workers to see the evolution of my code. It would seriously freak them out and I probably wouldn’t have a job anymore (don’t remind me that I already worked myself out of development.) So here’s what I like to do: Run a Local Instance of Oracle on my Machine and Develop My Code Privately I take a copy of development – that’s what source control is for afterall – and run it where no one else can see it. I now get to be my own DBA. If I need a trace – no problem. If I want to run an ASH report, no worries. If I need to create a directory or run some DataPump jobs, that’s all on me. Now when I get my code ‘up to snuff,’ then I will check it into source control and compile it into the official development instance. So my teammates suddenly go from seeing no program, to a mostly complete program. Is this right? If not, it doesn’t seem wrong to me. And after talking to Chet in the car on the way to the local cigar bar, it seems that he’s of the same opinion. So what’s so wrong with coding directly into a development instance? I think ‘wrong’ is a bit strong here. But there are a few pitfalls that you might want to look out for. A few come to mind – and I’m sure Chet could add many more as my memory fails me at the moment. But here goes: Development instance isn’t properly backed up – would hate to lose that work Development is wiped once a week and copied over from Prod – don’t laugh Someone clobbers your code You accidentally on purpose clobber someone else’s code The more developers you have in a single fish pond, the greater chance something ‘bad’ will happen This Isn’t One of Those Posts Where I Tell You What You Should Be Doing I realize many shops won’t be open to allowing developers to stage their own local copies of Oracle. But I would at least be aware that many of your developers are probably doing this anyway – with or without your tacit approval. SQL Developer can do local file tracking, but you should be using Source Control too! I will say that I think it’s imperative that you control your source code outside the database, even if your development team is comprised of a single developer. Store your source code in a file, and control that file in something like Subversion. You would be shocked at the number of teams that do not use a source control system. I know I continue to be shocked no matter how many times I meet another team running by the seat-of-their-pants. I’d love to hear how your development process works. And of course I want to know how SQL Developer and the rest of our tools can better support your processes. And one last thing, if you want a fun and interactive presentation experience, be sure to have Chet in the room

  • How does Visual Studio's source control integration work with Perforce?

    - by Weeble
    We're using Perforce and Visual Studio. Whenever we create a branch, some projects will not be bound to source control unless we use "Open from Source Control", but other projects work regardless. From my investigations, I know some of the things involved: In our .csproj files, there are these settings: <SccProjectName <SccLocalPath <SccAuxPath <SccProvider Sometimes they are all set to "SAK", sometimes not. It seems things are more likely to work if these say "SAK". In our .sln file, there are settings for many of the projects: SccLocalPath# SccProjectFilePathRelativizedFromConnection# SccProjectUniqueName# (The # is a number that identifies each project.) SccLocalPath is a path relative to the solution file. Often it is ".", sometimes it is the folder that the project is in, and sometimes it is ".." or "..\..", and it seems to be bad for it to point to a folder above the solution folder. The relativized one is a path from that folder to the project file. It will be missing entirely if SccLocalPath points to the project's folder. If the SccLocalPath has ".." in it, this path might include folder names that are not the same between branches, which I think causes problems. So, to finally get to the specifics I'd like to know: What happens when you do "Change source control" and bind projects? How does Visual Studio decide what to put in the project and solution files? What happens when you do "Open from source control"? What's this "connection" folder that SccLocalPath and SccProjectFilePathRelativizedFromConnection refer to? How does Visual Studio/Perforce pick it? Is there some recommended way to make the source control bindings continue to work even when you create a new branch of the solution?

  • When to use UserControl vs. Control in Silverlight?

    I'm just getting my feet wet in Silverlight, and don't really understand the differences and pros/cons of creating a UserControl vs. creating a Control for the same task (as in when you right click on a selection in Expression Blend, for instance). It seems like selecting "Make Into Control" just creates a new template for the base type you specify, whereas creating a UserControl creates a whole new base class. Is that correct? In this particular instance, I'm creating a custom text box control that only takes numbers, and divides itself into 3 sections, storing 3 values into separate properties as pictured below. In this particular case, which would be best? Update (Additional Question): Why can't I use Template Binding with a UserControl, but I can with a Control? That's one reason I thought that making a UserControl might not be the right decision.

  • How do I add programmatically-generated new files to source control?

    - by Alex Basson
    This is something I've never really understood about source control, specifically Subversion (the only source control I've ever used, which isn't saying much). I'm considering moving to git or Mercurial, so if that affects the answer to my question, please indicate as such. Ok. As I understand it, every time I create a new file, I have to tell SVN about it, so that it knows to add it to the repository and place it under control. Something like: svn add newfile That's fine if I'm the one creating the file: I know I created it, I know its name, I know where it lives, so it's easy to tell SVN about it. But now suppose I'm using a framework of some kind, like Rails, Django, Symfony, etc., and suppose I've already done the initial commit. All of these frameworks create new files programmatically, often many at once, in different directories, etc. etc. How do I tell the source control about these new files? Do I have to hunt each one of them down individually and add them? Is there an easier way? (Or am I possibly misunderstanding something fundamental about source control?)

  • Replacing .NET WebBrowser control with a better browser, like Chrome?

    - by Sylverdrag
    Is there any relatively easy way to insert a modern browser into a .NET application? As far as I understand, the WebBrowser control is a wrapper for IE, which wouldn't be a problem except that it looks like it is a very old version of IE, with all that entails in terms of CSS screw-ups, potential security risks (if the rendering engine wasn't patched, can I really expect the zillion buffer overflow problems to be fixed?), and other issues. I am using Visual Studio C# (express edition - does it make any difference here?) I would like to integrate a good web browser in my applications. In some, I just use it to handle the user registration process, interface with some of my website's features and other things of that order, but I have another application in mind that will require more err... control. I need: A browser that can integrate inside a window of my application (not a separate window) A good support for CSS, js and other web technologies, on par with any modern browser Basic browser functions like "navigate", "back", "reload"... Liberal access to the page code and output. I was thinking about Chrome, since it comes under the BSD license, but I would be just as happy with a recent version of IE. As much as possible, I would like to keep things simple. The best would be if one could patch the existing WebBrowser control, which does already about 70% of what I need, but I don't think that's possible. I have found an activeX control for Mozilla (http://www.iol.ie/~locka/mozilla/control.htm) but it looks like it's an old version, so it's not necessarily an improvement. I am open to suggestions

  • C# : Direct3D in a control, AND fullscreen on a secondary monitor - what's the best way ?

    - by Led
    I'm working on a C# application that needs to use Direct3D in a control in a windows form, AND (at the same time) fullscreen on a secondary monitor. Basically, I want a Windows Forms application on one screen with a user-interface to control the graphics, and I'd like to show preview-graphics in a small control, and full-blown superduper megafancy graphics fullscreen on a secondary monitor. What's the best way to approach this? (For example, I know XNA can render in a Windows Forms control, but is it possible to then add a fullscreen window on another monitor as well?)

  • How I can get information about the scrollbars of an Webbrowser control instance or the IE Webrowser?

    - by Salvador
    I need to get information about the scrollbars (position, size, visibility) of a Webbrowser control of an external application, I tried using the GetScrollBarInfo function from my previous question, but the function always return false, I checked this function with another applications and works fine , but not with the IE or the Webbrowser control. So how I can get information about the scrollbars of an Webbrowser control instance or the IE Webbrowser?

  • C# Console Application: Preventing Control-C from being printed?

    - by Alan
    Hi. I have a console app, and I want to capture Control-C and shutdown gracefully. I have the following code: Console.CancelKeyPress += new ConsoleCancelEventHandler((o, e) => { Logger.Log("Control+C hit. Shutting down."); resetEvent.Set(); }); And the output windows shows: 6/16/2010 3:24:34 PM: Control+C hit. Shutting down. ^C Is there a way to prevent the control-c character ^C from appearing? It's not a huge deal, but for some reason Ill be fixated on it because I'm anal like that.

  • Which is faster when animating the UI: a Control or a Picture?

    - by Christopher Walker
    /I'm working with and testing on a computer that is built with the following: {1 GB RAM (now 1.5 GB), 1.7 GHz Intel Pentium Processor, ATI Mobility Radeon X600 GFX} I need scale / transform controls and make it flow smoothly. Currently I'm manipulating the size and location of a control every 24-33ms (30fps), ±3px. When I add a 'fade' effect to an image, it fades in and out smoothly, but it is only 25x25 px in size. The control is 450x75 px to 450x250 px in size. In 2D games such as Bejeweled 3, the sprites animate with no choppy animation. So as the title would suggest: which is easier/faster on the processor: animating a bitmap (rendering it to the parent control during animation) or animating the control it's self?
