• Word 2007 Question

  - by Lijo

  Hi Team, While preparing a Word 2007 document, I made a mistake. (Not to say I don't have any other copy of the document) While formatting (as a try) I applied the style "Apply Style to Body to match selection". This caused the document to go totally in a wronfg format - having numbers even in tables. Have you ever faced this? Could you please tell how to correct it? Hope you would be kind enough to answer this even though it is not striclty technical. Thanks Lijo

• iPhone SDK: am I still allowed to develop with SDK 3.1.3 on Leopard?

  - by BoltClock

  Mac OS X Snow Leopard's been in stores for a while now. Sadly, the Mac that I'll be developing on is still running Leopard, and I don't have admin access to the Mac either so I can't do anything about the OS version. Therefore I can only use iPhone SDK 3.1.3, which we've obtained thanks to this answer, to start building apps on that Mac. Am I still allowed to develop apps with this setup and deploy for iPhone OS 3.x to the App Store? Keyword is allowed because all I've seen so far are technical questions/answers, but I'm not certain if Apple's going to be a jerk and shun me because I can't use a Snow Leopard Mac despite having only started this year (and I don't even want to get started about iPhone SDK 4's revised agreement, not with its NDA still in place...).

• Java applet - access denied to file on same web server

  - by me_here

  I've written a simple Java applet to generate a technical image based upon some data in a CSV file. I'm passing in the CSV file as a parameter to the applet: <applet code = "assaymap.AssayMapApplet" archive = "http://localhost/applet_test/AssayMap.jar" height="600px" width="800px"> <param name="csvFile" value="http://localhost/applet_test/test.csv"> </applet> As far as I understood applet security restrictions, an applet should be able to read data from the host they're on. These applets here http://www.jalview.org/examples/applets.html are using the same approach of passing in a text data file as a parameter. So I'm not sure why my own applet isn't working. The error message I get thrown is: Error with processing the CSV data. java.security.AccessControlException: access denied (java.io.FilePermission http:\localhost\applet_test\test.csv read)

• Can you explain to me git reset in plain english?

  - by e-satis

  I have seen interesting posts explaining subtleties about git reset. Unfortunately, the more I read about it, the more it appear that I don't understand it fully. I come from a SVN background and git is a whole new paradigm. I got mercurial easily, but git is much more technical. I think git reset is close to hg revert, but it seems there are differences. So what exactly does git reset do? Please include detailed explanations about: the options --hard, --soft and --merge; the strange notation you use with HEAD such as HEAD^ and HEAD~1; concrete use cases and workflows; consequences on the working copy, the HEAD and your global stress level. I will put a bounty on this ASAP cause it's really important and I find the git doc cryptic. Holly blessing and tons of chocolate/beer/name_your_stuff to the guy who makes a no-brainer answer :-)

• Silverlight Data Access - how to keep the gruntwork on the server

  - by akaphenom

  What technologies are used / recommended for HTTP Rpc Calls from Silverlight. My Server Side stack is JBoss (servlets / json_rpc [jabsorb]), and we have a ton of business logic (object creation, validation, persistence, server side events) in place that I still want to take advantage of. This is our first attempt at bringing an applet style ria to our product, and ideally we keep both HTML and Silverlight versions. For better or worse the powers that be have pushed us down the silverlight path, and while flex / java fx / silverlight is an interesting debate, that question is removed from the equation. We just have to find a way to get silverlight to behave with our classes. Should I be defining .NET Class representation of our JSON objects and the methodology to serialize / deserialize access to those objects? IE "blah.com/dispenseRpc?servlet=xxxx&p1=blah&p2=blahblah creating functions that invoke the web request and convert the incomming response string to objects? Another way would be to reverse engineer the .NET wcf(or whatever) communications and implement the handler on the Java side that invokes the correct server side code and returns what .NET expects back. But that sounds much trickier. T

• What is your best programmer joke?

  - by hmason

  When I teach introductory computer science courses, I like to lighten the mood with some humor. Having a sense of fun about the material makes it less frustrating and more memorable, and it's even motivating if the joke requires some technical understanding to 'get it'! I'll start off with a couple of my favorites: Q: How do you tell an introverted computer scientist from an extroverted computer scientist? A: An extroverted computer scientist looks at your shoes when he talks to you. And the classic: Q: Why do programmers always mix up Halloween and Christmas? A: Because Oct 31 == Dec 25! I'm always looking for more of these, and I can't think of a better group of people to ask. What are your best programmer/computer science/programming jokes?

• How to debug unreleased COM references from managed code?

  - by Marek

  I have been searching for a tool to debug unreleased COM references, that usually cause e.g. Word/Outlook processes to hang in memory in case the code does not call Marshal.ReleaseCOMObject on all COM instances correctly. (Outlook 2007 partially fixes this for outlook addins, but this is a generic question). Is there a tool that would display at least a list of COM references (by type) held by managed code? Ideally, it would also display memory profiler-style object trees helping to debug where the reference increment occured. Debugging at runtime is not that important as being able to attach to a hung process - because the problem typically occurs when the code is done with the COM interface and someone forgot to release something - the application (e.g. winword) hangs in memory even after the calling managed application quits. If such tool does not exist, what is the (technical?) reason? It would be very useful for debugging a lot of otherwise very hard to find problems when working with COM interop.

• Low noise sites to keep track of news related to computers & programming?

  - by Sridhar Ratnakumar

  I am aware of sites like Slashdot and Ars Technica. Unfortunately they publish way too many articles per day. Ars Technical: 100 posts per week Slashdot: 179 posts per week And I prefer not to waste my attention over reading about 180 posts (even if I were to skim) every week. Is there a site that provides only important news - excluding not-so-important news items like top 6 iPad apps that someone is dying to try out (but haven't done yet; still thinks their readers/advertisers care about it)?

• Which persistent & lightweight queue messaging for cross domain (> 2) data exchange with rails integ

  - by Erwan

  Hi all, I'm looking for the right messaging system for my needs. Can you help me ? For now, there won't be a huge amount of data to process, but I don't want to be limited later ... The machines are not just web servers, so the messaging tool should be lightweight, even if processing is not very speed. When some data change on a server, all servers should have the information and process it locally. (should I create one channel per server on each of them ?) The frontend is written on Rails, so it is important, in order to simplify the development, that there is a gem / plugin to manage communications and data sent. At this time : RabbitMQ + workling seems to fit my needs. Could this be a right choice ? ActiveMQ make me afraid, because of Java (I really don't know very well Java, but it seems to me to be big CPU consumer) Others don't seem to be as mature as them. There might be lot of development using this kind of technology, so I can't go to the wrong way ! Thank you for help.

• Reducing piracy of iPhone applications

  - by Alex Reynolds

  What are accepted methods to reduce iPhone application piracy, which do not violate Apple's evaluation process? If my application "phones home" to provide the unique device ID on which it runs, what other information would I need to collect (e.g., the Apple ID used to purchase the application) to create a valid registration token that authorizes use of the application? Likewise, what code would I use to access that extra data? What seem to be the best available technical approaches to this problem, at the present time? (Please refrain from non-programming answers about how piracy is inevitable, etc.)

• Handling changes in an interface shared across multiple solutions?

  - by Anthony Mastrean

  Our "main" solution is the development code: shared libraries, services, UI projects, etc. The other solution is an integration and automated tests solution. It references several of the development projects. The reason it is separate is to avoid interference with the development solution's unit test VSMDI file. And to allow us to play with different execution methods (other test runners, like Gallio or StoryTeller) without interfering with the development solution. Recently, an interface changed in the development solution, one of our test mocks implemented that interface. But, it was not updated because there was no warning at compile time because it was in another solution. This broke our CI build. Does anyone have a similar setup? How do you handle these issues, do you follow a strict procedure or is there some kind of technical answer?

• Client Side Development - In Process/Completed Indicator Preferences?

  - by Brian

  Hello, I have been doing more client-side development, managing the UI on the client and submitting data to the server via web service calls. I'm not looking for implementation details, but was curious on developer preferences for displaying an operation in process and what to display when completed or even failed. As a for instance, just for clarification sake, what if you are submitting a profile form's data to a web service. I want to display that something's happening to the user, and give them a message that the form submitted successfully. I've in the past used a twitter-style message (that appears at the top), modal dialogs... I was curious what worked for others and any advice (what did the users like/not like, etc.). Again, technical details aren't needed. Thanks.

• Getting a summary of comments in Jira

  - by Ross Alexander

  I currently maintain a Jira system at work and I have been tasked with a rather strange request which is too find a way of 'making a summary of a comment'. In the ideal situation this would allow a user to write a comment and a quick summary however I doubt this is something available in Jira / something that is feasible. Alternatively a summary of all comments would be nice that will allow our technical writers a way to clarify fixes through the information in the comments. If any one out there has ANY suggestions or ideas on this they are most welcome :) Sorry if this question is slightly general but I cannot find any thing that remotely helps on google, wondering if any Jira experts can push me in the right direction. Thanks

• Storing ASP.Net MVC Views in the Database

  - by Adam Albrecht

  For an ASP.Net MVC application, I'm interested in storing some views and/or partial views in the database so that a few semi-technical users can do some basic view logic. Does anyone have any tips or lessons from experience on doing this? I know Phil Haack wrote a blog post on this about a year ago. He used IronRuby for scripting his views, (which would be fine for me). He created a quick proof-of-concept, but I can't find any other information on the topic. Any ideas, thoughts, tips, etc would be appreciated. Thanks!

• Setting image DPI in relation to height/width C#

  - by Aaron

  Hi, I'm writing an application to send some images to a third party, and the images must be 200x200 DPI. The image is a Bitmap and is sized at 500 width and 250 height. The first time I tested the images with the third party, my resolution was incorrect. I merely used image.SetResolution(200,200) to correctly set it to 200x200. This, however, only changed the resolution tag for the image and did not properly, according to my third party technical contact, adjust the image height and width. Is there a ratio that I can use so that for each X units I increment the resolution, I merely increment the corresponding height or width Y units? I thought that I could just increment resolution without having to increment height or width. Thank you, Aaron.

• Find cheapest price for X number of days

  - by user76152

  Hey 'FLow. I have a technical challenge for you regarding an algorithm. Lets say I have this list of days and prices: List<ReservationPrice> prices = new List<ReservationPrice>(); prices.Add(new ReservationPrice { NumberOfDays = 1, Price = 1000 }); prices.Add(new ReservationPrice { NumberOfDays = 2, Price = 1200 }); prices.Add(new ReservationPrice { NumberOfDays = 3, Price = 2500 }); prices.Add(new ReservationPrice { NumberOfDays = 4, Price = 3100 }); prices.Add(new ReservationPrice { NumberOfDays = 7, Price = 4000 }); What I would like to able to do now is: give me the best price from the list based on a number of days. So if ask for 3 days the best price from the list is from child one (1000) and two (1200), but there are of course different combinations you would have to try out at first. How would an algorithm that found the best price from this list look like ? Thank you!

• merging two duplicate contacts/ColdFusion

  - by jil

  having to do with data integrity - I maintain a coldfusion database at a small shop that keeps addresses of different contacts. These contacts sometimes contain notes in them. When you are merging two duplicate contacts, one may be created in 2002 and one in 2008. If the contact in 2002 has notes prior to 2008, my question would be does it matter if you merge these contacts and keep the 2008 contact's ID number? Would that affect the data integrity or create any sort of issues with the notes earlier than 2008? I hope I've accurately described my scenario, as I am not familiar with the proper technical terms. I really appreciate the help sir!

• Unable to connect to a local MYSQL server on wireles LAN.

  - by Arnab

  Ok, Here is the technical description. My laptop's config: Ip Adress:192.168.2.5 Mysqlserver 5.0 on port : 3306 Operating system: Ubuntu jaunty (9.04) 3306 is open for both incoming and outgoing. My friend's laptop config: Ip Adress:192.168.2.4 Mysqlserver 5.0 on port : 3306 Operating system: Windows XP pro 3306 is open for both incoming and outgoing. Both are on a wireless LAN connected through a belkin router (192.168.2.1) Both the MYSQL servers have been given the sufficient GRANT privileges. I am also able to connect from 192.168.2.4 to 192.168.2.5's MYSQL instance but the vice versa is not happening. I am getting an (100061) error. Tried Telnetting on 3306; again happening from 192.168.2.4 to 192.168.2.5 but not the vice versa. Am I doing something wrong? Kindly suggest.

• Which development Language is best suited to Network Inventory

  - by dastardlyandmuttley

  Dear stackoverflow I hope this is the corrcet type of question for stackoverflow to consider I would like to develop a "Hard Core" application that performs Network Inventory. High level requirements are Work on Windows and UNIX networks it has to be extremly performant it has to be 100% accuarate (massively) scalable and fun to write The sort of details I am after is manufacturer and versions of all major workstation hardware components such as motherboard, network card, sound card, hard drives, optical drives, memory, BIOS details, operating system information etc. I dont want to have to distribute a client on each workstation to collect the information although i will require automatic worksattion discovery I would value your thoughts on the best development language to employ I know there are products such as NEWT and stuff like nmap... I would like to do this type of technical programming myself "from scratch" Warm Regards DD

• Why do C# automatic properties not support default values like VB 2010?

  - by Rob van Groenewoud

  Looking at the new VB 2010 features, I stumbled upon support for Auto-Implemented Properties. Since I'm working with C#, this seemed quite familiar, but I noticed that VB did add a feature I would love to have in C#: setting a arbitrary default value for the auto-implemented property: I really like the clean usage of auto-properties in C#. This would save us the effort of introducing a backing field and hooking it up to the property everytime we simply need a default value, thereby cluttering up the code unnecessarily. I was wondering why this wasn't introduced in C# as well? What could be the rationale for not doing this? Is a syntax discussion going on, or are there technical limitations to implementing this?

• If you can't do a Support Role, does this mean you should not be in development?

  - by Alex

  Hi, I've been shifted around roles a lot, and have been put in a support role which seems to deal out a lot of rubbish due to poor business management. Anyway, my line manager says that he's not sure he would recommend me for a developer role as they regard support as a poor technical role. What I resent is the fact that not all the information is available to us about what we're supporting and I miss coding. This thing I'm supporting has been regarded as a disaster when it went in and is still highly unstable. The thing is...does he have a point about Support roles being under developers, or are they completely two different kettle of fish?

• Can I use Catalyst to display images or graphs?

  - by Octopus

  I have simple Perl/CGI scripts based web server which is mainly used to display graphs and images. I am looking to make it more technical and come to know about Catalyst. I have installed all the required Perl modules on my test platform and created an application called myweb. Also, I am going through the Catalyst documents to reach my goal but nothing helpful yet. Is Catalyst helpful to display images/graphs on web? How can I use my existing CGI/Perl scritps with Catalyst? Any example would be really appreciated.

• Scrum: What if the Product Owner has tasks?

  - by Lauren J

  I have just started working with a team that has picked up some aspects of Scrum (two week timeboxing) but not others (the team does not currently agree to all estimates or to the number of points in a sprint, but I'll change this soon.) The product owner is also a technical resource (scientist) with some development background. Is it appropriate to have the product owner's tasks (which mostly involve research) mixed in with the team's tasks (some of which are research and some development). I have looked at a lot of resources and not found an answer. Thanks!

• How can you prevent an individual window being captured by Print-Screen?

  - by John

  I noticed a few times than when I print-screen while Media Player is running, the content is replaced with a grey rectangle. I've no idea if it's deliberate due to DRM, or some technical issue, but it struck me that being able to deliberately block screen-capture might be a useful feature in some scenarios. I am not looking to fix the problem, but replicate it! Is there some specific message each HWND gets for print-screen - does Windows do a special repaint or simply dump buffers to the clipboard? I guess I'd prefer to focus this on Win32 specifically, but as long as it's Windows-related then fine.

• VB.net Edit-And-Continue: ignore "unable to apply this change while debugging"

  - by FastAl

  When using VB.Net (2008) and paused in debugging, Edit-And-Continue is a great time-saver. However if you change any module/class-level information (variable, sub/function signature, etc), you get the error message like this: "unable to apply this change while debugging" While I can understand the technical challenge to making this work (and why it would be hard), it leaves me in a tight spot with just a few options: 1) Restart and recompile and get the program back to the same state 2) Continue debugging without making the change, and risk forgetting 3) Type up a reminder note to make the change All of which are annoying. Now I know that option '4) Just actually make the change' may not be possible. but does anybody know how to enable the following 'technically easy' possibility? 4) Let me change the code, get it flagged with the purple squiggly underline, so I can save it, but just ignore the change until recompile I have checked the Tools|options|debug|edit and continue, nothing appears to let me do this. thanks!
