• Suggestions for a mashup application

  - by Raffo

  I have to write a mashup application for an university course and I have to use some APIs, but I need to choose by myself what to use and what the final application should do. Unfortunately I never made an application like this, so I'm not sure what to do... I don't want to code a stupid app which uses google maps' APIs since the web seems to be full of stuff like this. Have you got any suggestion for me? Is there any mashup web app you want that's still not there?? I can use JAVA, GWT (and google app engine of course) or python, but I also accept suggestions for other languages. Thank you in advance!

• recommendations for rich scalable internet application

  - by Wouter Roux

  I am planning to develop a web application that must perform the following actions: User authentication allow authenticated user to download data from USB device (roughly 5 meg data) upload the data from the USB device to processing server process the data and display the results to the user further requirements/restrictions: the USB driver supports windows (2000, XP, Vista, 7) the application must support IE, Firefox and Chrome the USB driver must be installed when pointing to the web application the first time the USB driver exposes functionality through exported functions in dll scalability and eye candy is important server details: Windows Server 2008 Enterprise x64, IIS 7.0, SQL server 2008 With the limited details specified: What technology would you recommend? (eg silverlight/asp.net mvc/wcf). What practices/patterns/3rd party controls would you recommend?

• kill -9 and production application

  - by valodzka

  Which problem can cause kill -9 in production application (in linux to be exact)? I have application which do some periodical work, stopping these takes long time, and I don't care if some jobs will be aborted - work can be finished by new processes. So can I use kill -9 just to stop it immediately or this can cause serious OS problems? For example, Unicorn, uses it as normal working procedure: When your application goes awry, a BOFH can just "kill -9" the runaway worker process without worrying about tearing all clients down, just one. But this article claims: The -9 (or KILL) argument to kill(1) should never be used on Unix systems

• Web Application Translation, methods and tools

  - by CiscoIPPhone

  I've developed a web application. It needs to be translated to languages other than English in the future, and ideally the translators shouldn't need to know HTML/JS/C++ to provide the translation. The server side of the web application is written in C++ and the majority of the localised text is in the HTML files. My question is: What approaches are there to translating web applications? - Are there any existing tools that would enable a translator who doesn't understand HTML to translate a site? Should I write an application that extracts the localised text from a html file and can re-substitute translated text? Do you just provide the html file to your translators to be localised? I'm aware the question isn't strictly programming related but the solution may involve programming and it may require some software engineering.

• Anyone using IronPython in a production application?

  - by Scott P

  I've been toying with the idea of adding IronPython for extending a scientific application I support. Is this a good or horrible idea? Are there any good examples of IronPython being used in a production application. I've seen Resolver, which is kind of cute. Are there any other apps out there? What I don't get is this. Is it any easier to use IronPython than to just use something like code DOM to create script like extensibility in your application? Anyone have some horror stories or tales of glorious success with IronPython / IronRuby?

• How To Make Moving News Bar in Windows Forms Application without Timer

  - by Ehab Sutan

  I'm making a desktop application in C# which contains a moving News Bar labels. I'm using a timer to move these labels but the problem is that when i make the interval of this timer low (1-10 for example) the application takes very high percentage of CPU Usage, And when i make it higher(200 -500 ) the movement of the labels becomes intermittent or not smooth movement even that the user may not be able to read the news in Comfortable way. ((More Information)) it is Windows form application. the way i move the labels is as follows : the news items from RSS feeds are represented in a group of linklabels. All these linklabels are added to a flowlayout container. The timer moves the whole flowlayout container. I found this way according to my knowledge the best way to making the news bar. If you have better idea or solution please help

• c# application and configuration settings

  - by Maks

  Hi, I never used Settings class before but I found some articles on CodeProject which I'm currently reading (for example http://www.codeproject.com/KB/cs/PropertiesSettings.aspx) but so far I didn't see how to save string array for getting it after application is started next time. For example my application has several FileSystemWatcher instances, with each instance several other directories are connected (for example one FSW instance is monitoring one directory for a change and when it happens it copies some file to several other directories), so I would have one string array with watched paths representing FSW instances, and string array for each of those paths, representing directories that are affected. My question is, what should I use (Settings class or something else), and how should I use that for storing application configuration that is variable number of string arrays? Emphasize is on something I could use very soon as I don't have too much time to make custom class (but would have to if I cannot find solution) or dig into some obscure hacks. Any tutorial link, code snippet would be very helpful. Thanks.

• Hitting a memory limit slows down the .Net application

  - by derdo

  We have a 64bit C#/.Net3.0 application that runs on a 64bit Windows server. From time to time the app can use large amount of memory which is available. In some instances the application stops allocating additional memory and slows down significantly (500+ times slower).When I check the memory from the task manager the amount of the memory used barely changes. The application keeps on running very slowly and never gives an out of memory exception. Any ideas? Let me know if more data is needed.

• Get application icon from ProcessSerialNumber

  - by Thomi

  I would like to get the application icon for all foreground applications running on my Mac. I'm already iterating over all applications using the Process Manager API. I have determined that any process that does not have the modeBackgroundOnly flag set in the processMode (as retrieved from GetProcessInformation()) is a "foreground" application, and shows up in the task switcher window. All I need is an API that gives me a CImageRef (or similar) that contains the application icon for a process. I'm free to use either carbon or cocoa APIs.

• What can I put in my software development blog to make it a good showcase of me?

  - by Sean

  I have been itching to write a software development blog for some time now. The best advice I've received about blog writing is "Write the blog you would have want to read". Its good advice but its only half the story, Once you write a blog it becomes your showcase on the Internet, it is bound to come up on any search conducted by a future colleague or employer. It can be a good thing or it can do some serious damage. So if there are any hiring managers out there, can you give me a few pointers on what it is in a blog that give you a good impression about candidate and/or the kind of stuff that causes you to throw the candidate's resume to the nearest bean? Does a blog have to come up with a clever piece of code every week? (Don’t think I can manage it) Is it OK to blog more then not about development methods to improved quality and productivity (have a lot of ideas about that). Can I blog about stuff I did not try first hand but seems noteworthy?

• Quicken like Windows Forms application

  - by WinFXGuy

  Hi All, I need to build a quicken like application, where data needs to be secure. I don't see any database being used by Quicken. I could use XML, MDF or Access database, but data is not secure in the tables. What is the best option? How does Quicken handle it? My application may also have document attachments as well. The functionality of this application is similar to quicken but not an accounting/financial in functionality. Thanks a bunch!

• Application lifecycle. How to run something only when application starts

  - by David

  I have a dialog popup to indicate how long I want an activity to run. Seems simple enough, but its difficult to determine when the activity is really starting. If the user opens the keyboard on a G1 and thereby goes into landscape, that reruns the activities onCreate method. I can't have a static for the class or even create an application class, because I can't determine when the 'application' goes away. Even after destroying the only activity, the application is apparently still alive. Is there a way to determine that onCreate has been called because of the keyboard being extended or landscape mode invoked? Thanks

• Using Network load balancing to distribute load for SharePoint2010 – Part3 of building my own development SharePoint2010 Farm

  - by ybbest

  Part1 of building my own development SharePoint2010 Farm Part2 of building my own development SharePoint2010 Farm Part3 of building my own development SharePoint2010 Farm In my last post, I have installed SharePoint2010 in one of the server (WFE One) and configured using the OOB SharePoint configuration wizard. In this post I will show you how to use OOB windows network load balancing to distribute load for SharePoint2010 site. 1. Install SharePoint in another server WFE Two (you can follow the steps in my last post), but instead of choosing create new Farm, you need to select “connect to existing farm” this time. 2. Click next then click retrieve database names button and select the farm configuration database. 3. Click next and enter the passphrase you specified when you first installed the SharePoint Farm. 4. Click the advanced settings and select Use this machine to host the web site. 5. Click OK to finish the configurations 6. Next, Install NLB in the two WFE (web front end) SharePoint servers 7. Configure NLB to create the cluster. Go to Start—Administrative Tools—Network Load Balancing Manager 8. Right-click the Network Load Balancing Clusters Node and select New Cluster. 9. Type in the host name that is to be part of the new cluster. 10. Type in the IP address for the cluster. 11. Select the Multicast for this cluster.(The default one is Unicast) 12. You can configure the Port Rules for the clustering , but I will leave the default here. 13. Add another WEF to the cluster. 14. Type in the host name that is to be part of the new cluster. 15. Set the Priority to 2. 16. Click Next to complete the cluster setup. 17. Create an entry in the DNS for the new cluster. 18. Add the binding to the IIS site in the IIS Manager 19. Change the Alternate access mapping for you default site collection from http://sp2010wefone to http://team 20. Browse to http://Team , you will be redirected to the SharePoint site.

• Remove all references to a DLL across all application domains

  - by ck

  I have a web application that dynamically loads assemblies based on database configuration entries to perform certain actions (dynamic plugin style architecture). The calls to the objects are in a Factory Pattern implementation, and the object is cached (in a static dictionary< within the Factory) as the calls can be made many thousands of times in a minute. The calls to this factory are made from both the main web application and a number of webservices, some in different assemblies/projects. When I need to update one of these DLLs, I have to recycle IIS to get the DLL released. As this has an impact on another application on the server, I wanted to know if there was a way I could release the DLL without restarting IIS?

• How to calculate vertext normals for a mesh in Java in OpenGL ES application?

  - by alan mc

  Can some one point me to Java code ( in Java not C or C++) that calculates all the normals for all the vertices of a mesh for OpenGL ES application. I need this for lighting. Lets say I have a cube with following vertices and indices: float vertices[] = { -width, -height, -depth, // 0 width, -height, -depth, // 1 width, height, -depth, // 2 -width, height, -depth, // 3 -width, -height, depth, // 4 width, -height, depth, // 5 width, height, depth, // 6 -width, height, depth // 7 }; short indices[] = { 0, 2, 1, 0, 3, 2, 1,2,6, 6,5,1, 4,5,6, 6,7,4, 2,3,6, 6,3,7, 0,7,3, 0,4,7, 0,1,5, 0,5,4 }; In above specific example how many normals we need ?

• bad_application error starting erlang gen_server application

  - by user313475

  I have written a simple erlang app using gen_server. When starting it with application:start(myapp), I get the following tuple... {error,{bad_application,{application,myapp ... (rest of my application config). There are no other error or warning messages. I have also tried to google examples of how to configure gen_server and also the error itself. I am surprised at how little information there is out there. I could start trying to debug OTP?? Any pointers would be appreciated.

• Should I go back to college and graduate with a poor GPA or try to jump into an entry-level development position? [closed]

  - by jshin47

  I once attended a top-10 American university but I am currently not in school for several different reasons. Chief among them is that I did very poorly two semesters and even failed one of them (got two F's) which put me in automatic suspension. My major is not CS but math. I am in a pickle at the moment. After I was suspended I got a job at a niche IT company in the area. I am employed as something of an IT generalist; my primary responsibilities are Windows systems administration/networking but I also do some Android, iOS, and .NET development. I have released a few apps to the app store under my name and my company's name, and we have done work for a few big clients. I started working at my job about 1.5 years ago and I am somewhat happily employed but I do not see it as a long-term fit because it is a small company with little opportunity to advance. I would like to move out to California and particularly to the Bay Area to get a job at a more reputable or exciting company, even at a lower rate of pay, but I am not sure if I should do that or try to go back to school. If I went back to school, it would take 1-1.5 years to graduate and some $. Best case scenario I would graduate with a 2.9 or 3.0 GPA. It is a top-10 school, but that's a crappy GPA. If I do not go back to school, I will be a field where most people have degrees, without a degree. If anything goes wrong I could be really screwed as I feel I will get no respect without a degree. On the other hand I really would like to get started in the field and get more serious about developing good development practices, learning new languages/frameworks, and working with people who know a lot more than I so I can learn and grow as a developer and eventually do my own thing. Basically, I am wondering: Should I just go back to school? How much does the bad GPA / good school reputation weigh in? What about the fact that I am a Math major and not a CS major (have never taken a CS course)? Does my skill set as something of a generalist bode well for me finding work at a start up in the Bay Area? If not (2), should I hunker down and focus on producing a really good (or a few medicore) iOS apps? Android apps? etc... How would you look at someone who did great in HS, kind of goofed off in college and eventually quit, and got into development? Thanks for any thoughts or input.

• Get Excel.Application object from Process or hwnd in .NET

  - by Abiel

  In C# I am trying to get an instance of an Excel.Application object from a Process object. This seems like it should be really simple yet I cannot figure it out and cannot find an example. To repeat, I have a System.Diagnostics.Process object that I know refers to a running Excel instance. I now need to recover a Microsoft.Office.Interop.Excel.Application object that refers to the process so that I can go about manipulating the Excel application from C#. In case it makes it any simpler, I also have the HWND id and window text associated with the active Excel window. Thanks.

• Implementing a 'Send Feedback' feature in a Java desktop application

  - by William

  I would like to implement a 'Send Feedback' option in a Java desktop application. One which will pop up a box for the user to enter a comment, then send it to us along with a screenshot of the application window. How would be the best way to communicate the data to us? Two obvious solutions spring to mind: Email - I'm thinking that the application would connect to an SMTP server set-up by us, with the username/password somehow hidden in the code. SMTP over SSL for security (not of the data being sent, but of the SMTP username/password). Web service - pretty self explanatory. Which of these would be best, or is there a better alternative?

• Set Java Application's virtual machine max memory without access to VM parameters because of custom

  - by Tom

  I'm using a Java application which allows you to import custom files. On import, these files are loaded into memory. The problem is that the files I want to import are very big, this causes an OutOfMemory exception. The crash log also informs me that the VM was started with the java parameter "-Xmx512m", I want to alter this to "-Xmx1024m" so that I got double the memory available. The problem is that this application is using it's own JRE folder and that there's a launcher written in C which is calling the jvm.dll file. In any way, java.exe or javaw.exe are never called and thus I cannot set these parameters myself (if I delete these executables it doesn't matter, can still run the application - this is not the case with the dll). So, my question is, can I set this VM parameter in an other way? I'm even willing to alter the JRE files if there is no other way.

• Best way to get an Application Context into a static method in Android

  - by Slapout

  I'm working on an Android application that has several Activities. In it I have a class with several static methods. I would like to be able to call these methods from the different Activities. I'm using the static methods to load data from an xml file via a XmlResourceParser. To create a XmlResourceParser requires a call on the Application Context. So my question is, what is the best way to get a reference to the Application Context into the static methods? Have each Activity get it and pass it in? Store it somehow in a global variable?

• visual c# 2008 database application examples

  - by Omar

  hi, i just have a few weeks programming with vc# (2008) and i'm trying to build an application (winforms) and i have the following problem... i need my application to work with and without connection to the mssql database, this sounds like piece of cake for our friend DataSet right? i can persist the data as XML or binary until i can reach the database and the DataSet will magically sync; all without bothering the user. The problem is... the few books i have read just mention that logic like a fairy tale but dont give any practical example of how to do it, can you point me to one example/demo/whatever i can read or download of an application with (equal or) similar logic?

• Visual Studio detaches from application as soon as debugging starts

  - by rwmnau

  I have a web application that I've always been able to run in Visual Studio and it debugs just fine (breakpoints work, I can pause execution, etc). Recently, the behavior changed suddenly, and a few things happen: I start debugging, it lauches IE and loads the application, but after a few seconds (sometimes the page hasn't even displayed yet), Visual Studio acts as if debugging has stopped - I'm able to edit code in VS again, and the "Play" button on the toolbar is enabled. The application continues to run in the IE window just spawned, but I'm not attached to it During this few seconds that VS is "debugging", because it detaches, my breakpoints show as hollow - as if I'm set to "Release" mode and they won't be hit. In fact, I have a breakpoint set in Page_Load, and it skips right by. I've checked, and I'm set to debug mode, though the compile mode dropdown is missing from my toolbar (I checked in the build properties to ensure I was in debug mode). Can anybody shed some light here?

• Application Runs when Debugging but not when Published.

  - by corymathews

  When publishing my web application and then running it will return the error "Could not load file or assembly 'BaseApplicationName' or one of its dependencies. An attempt was made to load a program with an incorrect format." However if I run the application through debugging (f5) it runs correctly. I guess what it comes down to is what differences are there when running an application through debugging vs publishing it that would cause a problem like this? When publising I have it set to delete all existing. History of how it started... I added the 32 bit Oracle.DataAccess dll to my 64 bit system. It would not work and crash giving the same error as above but with the Oracle.DataAccess name instead of the baseApplicationName. I have since removed all references to it and removed the dll to try and get it to run without it once again. Any advice?
