• Xcode: How-to bind a key that triggers application to appear (background daemon)

  - by Shyam

  Hi, I am struggling to create a certain kind of application my Mac, using Xcode and Interface Builder (RubyCocoa). As I am a nuby (but understand some Ruby), I would like to know how I could let my interface appear only if a key is pushed (a toggle), while the program is running in the background. Similar behavior like when I'd press the F4-key to show Dashboard. Really neat would be if the program wouldn't be showing as running in the Dock, but as a funky icon in the top bar, like well "Growl". Thank you so much for your help, comments and feedback!

• Adobe Flex + Air or Java + JavaFX 2.0?

  - by kuyapangu

  Hey guys! I'm looking into a cloud-computing related career. I've recently graduated from school and have been meaning to study a new programming language. From what I understand, I need to get into RIA development for this. Flex and Java have certainly caught my attention, but I am torn as to whether focus on Flex then continue with Air, or study Java first and see how JavaFX 2.0 pans out, and then continue with Flex thereafter. I've no previous experience with either, and I'm sort of giving myself something like two years or so to learn. What do guys think? Thanks for the feedback! :)

• Simple installer for Visual C# Express 2008

  - by espais

  I am looking for some general feedback here. I have a very simple application that I created in VC# Express 2008, with no special dependencies. Now, I am going to release it as open source, and am curious as to how I should deploy it. Do I need to create an installer package with any dll's? Should I just zip up the *.exe file with a README? Also, how should I go about handling the requirement for the .NET framework that a C# program needs?

• How to disable UI control based on domain object's state?

  - by Subb

  Here's my problem. I have a somewhat complex domain object, which, depending on its state, responds to certain actions. I think the state pattern is pretty much the solution for that. However, I need to display which actions are possible at any moment in the UI. Ex: The domain object is an audio player. Some songs can't be skipped (like ads), so I need to disable the "next" and "previous" buttons in the GUI so the user have some kind of feedback of which action he can execute. I've looked at Swing's Action class (note: this is not a Java project), but I think I would need to keep every Actions in my domain object class (audio player), so it can enable or disable them depending on its own state (thus, affecting the UI). Is it the way to do it?

• DAO design pattern and using it across multiple tables

  - by Casey

  I'm looking for feedback on the Data Access Object design pattern and using it when you have to access data across multiple tables. It seems like that pattern, which has a DAO for each table along with a Data Transfer Object (DTO) that represents a single row, isn't too useful for when dealing with data from multiple tables. I was thinking about creating a composite DAO and corresponding DTO that would return the result of, let's say performing a join on two tables. This way I can use SQL to grab all the data instead of first grabbing data from one using one DAO and than the second table using the second DAO, and than composing them together in Java. Is there a better solution? And no, I'm not able to move to Hibernate or another ORM tool at the moment. Just straight JDBC for this project.

• Why is there no .NET Community Process?

  - by michielvoo

  I was doing some research into general topics of software engineering and I came across the Java Community Process website: The JCP is the mechanism for developing standard technical specifications for Java technology. Anyone can register for the site and participate in reviewing and providing feedback for the Java Specification Requests (JSRs), and anyone can sign up to become a JCP Member and then participate on the Expert Group of a JSR or even submit their own JSR Proposal. Seems like a good idea to me, and there are lots of very well written specifications and reference implementations on the JCP website. So why is there no .NET Community Process? Is that something that Microsoft could or should start? Maybe they could install it on Codeplex.net and hand over the keys to the community.

• C# dealing with invalid user input

  - by Zka

  Have a simple console app where user is asked for several values to input. Input is read via console.readline(). Ex Name: Fred //string Lastname: Ashcloud //string Age: 28 //int I would like to make sure that int and double types are entered and if the user enters garbage, lets him repeat the procedure. Example, if the user enters "28 years old" where age expects int the app will crash. What is the best way to check for these inputs? Right now I can only think of: while (!Int32.TryParse(text, out number)) { Console.WriteLine("Error write only numbers"); text = Console.ReadLine(); } Is there any other way to do this? try catch statements if one wants to give a more detailed feedback to the user? How in that case?

• XNA or C# Pop-up progress bar for the LoadContent() method

  - by Warlax

  Hey people, We wrote a small game using Microsoft's XNA Game Studio 3.1. The LoadContent() takes a long time because, other than loading models, and config files, we're also running some one-time (per run) terrain analysis. We are not C# or XNA programmers... we're Java programmers, and want to be able to give the user some feedback that the system is loading. Preferably, this will be through a simple pop-up with a progress bar that will say something simple like "loading please wait". The progress bar doesn't have to be a 0 to 1 progress bar, it can instead be one of those 'back and forth' progress bars. I was hoping for some quick copy-paste ready code to just do that - as it is not a central piece of our project, nor do we have a need to delve into too much documentation. I appreciate you time, effort, and possible donation. Thanks.

• Send through Email, or store in database?

  - by user156814

  I have wondered when it is best to send an email, and when its best to store data in a database/log file. Everytime a user wants to contact me or inform me of soething, I suppose an email is best.. but is an email always preferred over other ways, and in what cases. Possible reasons for being contacted I can think of are questions, suggestions, feedback, reporting abuse, advertising, etc... I assume email, "why add unnecessary things to the DB?", but I figure data in DB would be a lot easier to manage. Whats the better/best way to be informed of things like this.. What is the best way for you (webmaster) to be informed of something by users? through email, or some other way

• Stack recommendations for small/medium-sized web application in Python

  - by reto

  I'm looking for some recommendations for a python web application. We have some memory restrictions and we try to keep it small and lean. We thought about using WSGI (and a python webserver) and build the rest ourself. We already have a template engine we'd like to use, but we are open for some suggestions regarding the whole request handling (the controller). The application has to run in a single process and the requests have to be processed with multiple threads. We've looked at django, but we are a not sure if it fits into our memory budget. Your feedback is very welcome! Cheers, Reto

• Interview question - c#

  - by ltech

  I was tasked to conduct my first interview and would like to pose my question to this world for both their feedback on my question and also on their solutions. Question: I have a legacy system with users and files, the info of all files pertaining to a user are stored on a flat file. I want to upgrade this system by storing all info on a db, design tables, and create a C# system that will populate the new db as well as ftp the files to a new path. Define the desgin consideration and develop a prototype. Note: We are looking more for what design one would use and why rather than code that compiles. If it does then kudos to you and we will give it more weight. @Tim C, I did show the interviewee the file: User1234.txt UserID=1234 ParentPath=\\somewhere\nowehere\everywhere\1234 FileCount=20 File0=something0.ext .. File19=something19.ext @Tim C, I have never conducted an interview and I followed a script given to me by my senior developer who was absent.

• WCF Rest services for use with the repository pattern?

  - by mark smith

  Hi there, I am considering moving my Service Layer and my data layer (repository pattern) to a WCF Rest service. So basically i would have my software installed locally (WPF client) which would call the Service Layer that exists via a Rest Service... The service layer would then call my data layer using a WCF Rest Service also OR maybe just call it via the DLL assembly I was hoping to understand what the performance would be like. Currently I have my datalayer and servicelayer installed locally via DLL Assemblies locally on the pc. Also i presume the WCF REST services won't support method overloading hance the same name but with a different signature?? I would really appreciate any feedback anyone can give. Thanks

• I need to debug my BrowserHelperObject (BHO) (in C++ with Visual Studio 2008) after a internet explo

  - by BHOdevelopper

  Hi, here is the situation, i'm developping a Browser Helper Object (BHO) in C++ with Visual Studio 2008, and i learned that the memory wasn't managed the same way in Debug mode than in Release mode. So when i run my BHO in debug mode, internet explorer 8 works just fine and i got no erros at all, the browser stays alive forever, but as soon as i compile it in release mode, i got no errors, no message, nothing, but after 5 minutes i can see through the task manager that internet explorer instances are just eating memory and then the browser just stop responding every time. Please, I really need some hint on how to get a feedback on what could be the error. I heard that, often it was happening because of memory mismanagement. I need a software that just grab a memory dump or something when iexplorer crashes to help me find the problem. Any help is appreciated, I'll be looking for responses every single days, thank you.

• distributing R package with optional S4 syntax sugar

  - by mariotomo

  I've written a small package for logging, I'm distributing it through r-forge, recently I received some very interesting feedback on how to make it easier to use, but this functionality is based on stuff (setRefClass) that was added to R in 2.12. I'd like to keep distributing the package also for R-2.9, so I'm looking for a way to include or exclude the S4 syntactical sugar automatically, and include it when the library is loaded on a R = 2.12 system. one other option I see, that is to write a small S4 package that needs 2.12, imports the simpler logging package and exports the syntactically sugared interface... I don't like it too much, as I'd need to choose a different name for the S4 package.

• How to have tortoisesvn Always freeze svn:externals for tags

  - by dnndeveloper

  Is this possible with tortoiseSVN?: Always freeze svn:externals for tags the scenario is our trunk will always use the 'head' revision for externals, however when we create 'tags' we would like for them to have a revision set for externals to properly 'freeze' them at a specific point in time. Thanks! Update Thanks to everyone for your feedback/info. Since I could not find anything that would completely meet our needs (tried smartsvn and svncopy.pl) I made a console app that so far has passed all our test cases. A high level overview: The app takes a repository URL then looks for all externals and adds the last commit revision for them - I do a "svn info" and get the "commit revision". The app works with both folder and single file externals. Here is the source code and complete setup files: http://svnxf.codeplex.com/

• speed up the speed of a sql query to mysql?

  - by fayer

  in my mysql database i've got the geonames database, containing all countries, states and cities. i am using this to create a cascading menu so the user could select where he is from: country - state - county - city. but the main problem is that the query will search through all the 7 millions rows in that table each time i want to get the list of children rows, and that is taking a while 10-15 seconds. i wonder how i could speed this up: caching? table views? reorganizing table structure somehow? and most important, how do i do these things? are there good tutorials you could link to me? i appreciate all help and feedback discussing smart ways of handling this issue!

• Can you suggest good ways of generating URLS for viewing tagged content

  - by rikh

  For example, here on stack overflow the URL http://stackoverflow.com/questions/tagged/javascript+php will give you all questions tagged with javascript and php. The system I have allows tags with spaces in them, so the approach used here would not be a good fit for me. What character would you use to separate the tags, so the URLs are still human readable, google readable and web browser compatible. My gut feeling was to use commas. eg http://example.com/tagged/first+tag,second+tag Any feedback or suggestions would be welcome.

• How do you use Exslt.dyn (especially the 'evaluate' method) in Umbraco?

  - by jeffreypriebe

  I am trying to execute the string contained in an XSL variable. Umbraco has hooks for several Exslt pieces, but it seems the Exslt.dyn (Exslt.dynamic) is not one of them. How do you add it in? Acceptable methods (in order of preference: Writing your own XSLT extension (possibly using existing Umbraco code for Exslt Dynamic). Uploading the XSL from http://www.exslt.org/dyn/functions/evaluate/index.html into Umbraco. Modifying the Umbraco source to add it (possibly using existing Umbraco code for Exslt Dynamic). The reason I mention Exslt Dyanmic is because some Umbraco XSLT sources show a reference that I am assuming existing in some versions of Umbraco. I cannot find it in the source code, however. (Example: the XSL sources pasted in here: http://our.umbraco.org/projects/starter-kits/business-website-starter-pack/general-%28bugs,-feedback,-feature-requests%29/8085-Changing-the-first-day-to-fx-monday)

• if you have written programming book, what prompted you?

  - by aaa

  I noticed that quite a few authors visit the website. First of all, thank everybody who shared their knowledge. Now the question, what prompted you to write a book? was it desire to educate people, just wanted to write the book, financial gains, something else? was writing a book your idea or you were approached to write the book? were you happy with your final work, after editors have their say what feedback did you receive, positive negative neutral? I am warned this is maybe subjective question, I rest decision to close with moderators.

• Passing HttpFileCollectionBase to the Business Layer - Bad?

  - by Terry_Brown

  hopefully there's an easy solution to this one. I have my MVC2 project which allows uploads of files on certain forms. I'm trying to keep my controllers lean, and handle the processing within the business layer of this sort of thing. That said, HttpFileCollectionBase is obviously in the System.Web assembly. Ideally I want to call to something like: UserService.SaveEvidenceFiles(MyUser user, HttpFileCollectionBase files); or something similar and have my business layer handle the logic of how and where these things are saved. But, it feels a little icky to have my models layer with a reference to System.Web in terms of separation of concerns etc. So, we have (that I'm aware of) a few options: the web project handling this, and my controllers getting fatter mapping the HttpFileCollectionBase to something my business layer likes passing the collection through, and accepting that I reference System.Web from my business project Would love some feedback here on best practice approaches to this sort of thing - even if not specifically within the context of the above.

• Is this a good way to identify the type of a javascript object?

  - by FK82

  Apparently neither instanceof nor typeof deliver in terms of correctly identifying the type of every javascript object. I have come up with this function and I'm looking for some feedback: function getType() { var input = arguments[0] ; var types = ["String","Array","Object","Function","HTML"] ; //!! of the top of my head for(var n=0; n < types.length; n++) { if( input.constructor.toString().indexOf( types[n] ) != -1) { document.write( types[n] ) ; } } } Thanks for reading!

• hidden form element not bound?

  - by csetzkorn

  Is it standard/intended behaviour that the value of a hidden form field is not bound to the view model (nor is a query string value)? Example: <%= Html.Hidden("test", "13" )%> if my poco view model contains a property test it should be bound shouldn't it?! i have to set it explicitely in the controller at the moment which kind of defeats the objective doesn't it? bla( formviewmodel m, string test) { m.test = test; } any feedback appreciated. thanks! christian

• iCalcreator 2.6 event creation sent in an email w/o attachment

  - by Jonas

  G'day everyone, I am currently trying to send meeting invitations to Outlook recipients. After reading several blogs and various literature iCalcreator seems to be the most complete iCalendar PHP class available. And the documentation is just...crazily complete. If creating a iCal .ics file is OK, I can't find a nice way to send it by email to the attendees without having them to double click on an attachment. Just like Google Calendar and Outlook do, I would like to send emails that will automatically show the buttons Accept | Tentative | Decline upon reception without any other user action involved. If anyone ever had to realize that, I would be more than happy to get your feedback/help or even just relevant guidance. Thanks
