• Charts - Column chart with extra data

  - by Koran

  Hi, I have some data similar to the following chart: http://developer.yahoo.com/yui/examples/charts/charts-seriescustomization_clean.html Only difference is that for each of the fields - I have some other extra data - say For utlilities - I have a cash reserve for utility - as another field. I would prefer this data point to come above the utilities bar. I have been trying from morning to get this chart working, but I am unable to do so. Could you please let me know if it is possible - someway? Thank you very much in advance. Regards K

• How to configure build numbers in Visual Studio to enable dll comparison

  - by jaminto

  Hi Everyone- I am building a C# solution in Visual Studio 2008 that has several projects and project dependencies. I am looking for a way to change dll version numbers ONLY when the code that builds the project changes. I currently use Beyond Compare to compare my locally built version to the production file system. The goal is to ONLY deploy updated dlls. I am using autoincrementing version numbers, and each time you open visual studio and do a build, all dll version numbers increment. The same goes for a full solution rebuild and when a different developer does a build and tries to deploy. Is there a way that i can configure Visual Studio to ONLY increment the build number based on changed file contents? Is there an add in that will do this?It seems a binary comparison of these files will also fail because of the different version numbers within the dlls. Does anyone know of a better tool compare only the contents of dlls?Thanks in advance.

• Is there any need to get a Computer Science degree?

  - by Tom Moseley

  I've been a software developer for 20 years. i've been involved in language development and large data warehouse development. I've worked for start-ups that have gone public, and for government contractors, and I've written a published programming book. My knowledge is either self-taught or on-the-job. I've worked with some of the best and brightest, and they taught me well. I'm back in school now, and am weighing my options, deciding between a Computer Science and a business degree. My question is this. What do I gain, at this point in my career, by earning a Computer Science degree? I just don't know if a Computer Science degree, at this point, is a value-add on my resume. Edit: I'm working on completing an undergraduate degree.

• What some good books on software testing/quality?

  - by mjh2007

  I'm looking for a good book on software quality. It would be helpful if the book covered: The software development process (requirements, design, coding, testing, maintenance) Testing roles (who performs each step in the process) Testing methods (white box and black box) Testing levels (unit testing, integration testing, etc) Testing process (Agile, waterfall, spiral) Testing tools (simulators, fixtures, and reporting software) Testing of embedded systems The goal here is to find an easy to read book that summarizes the best practices for ensuring software quality in an embedded system. It seems most texts cover the testing of application software where it is simpler to generate automated test cases or run a debugger. A book that provided solutions for improving quality in a system where the tests must be performed manually and therefore minimized would be ideal.

• Get UPN or email for logged in user in a .NET web application

  - by DrStalker

  I'm not a .NET developer, and I have a feeling this would be trivial for someone who is: I have a C# web application that makes user of the user credentials of the logged in user. Currently it uses the SID which comes from System.Security.Principal.WindowsIdentity.GetCurrent().User.Value I need to get either the users UPN login or email address (as defined in active directory) instead of the SID. GetCurrent() returns an object of type WindowsIdentity; looking in the details for WindowsIdentity Members: MSDN: WindowsIdentity Members I can't see anything that looks like it would give me either the UPN or email in there. How can I pull up that information to use, either by feeding the SID into some other function or calling something different in the first place.

• Java Preprocessor in C#

  - by Olaseni

  Say I want to create a sort of Pre-processor for existing java code, so I can get the language specific keywords and objects, and then create routines that convert them to their Csharp equivalents, using Csharp code - what route should this take? I'm thinking of Regular Expressions, but I'm fuzzed. I have a bunch of about a 100 .java files and I need to convert them to csharp code in record time. I have manually done just about five of them and I have serious headaches already. Or are there any tools out there that already do that?

• XCode 3.2 does not mark unit test assert failures in the editor

  - by Cliff

  I've been off in Java land for about a month or so and now, upon returning to XCode I feel lost. I've upgraded 1st to 3.1.2 then recently to 3.2 and also got a new Mac with Snow Leopard so I'm not exactly sure when the problem surfaced. I just know that I used to get little red bubbles in my unit test next to the failing asserts and that no longer seems to happen. Is there a way to restore this? I've been trying to use Apple's own SenTesting framework instead of GoogleTools for mac like I used to. Should I revert to Google Tools? Does anyone have an answer?

• Decoding subsampled bitmaps in Android

  - by hgpc

  I decode bitmaps from the SD card using BitmapFactory.decodeFile. Sometimes the bitmaps are bigger than what the application needs or that the heap allows, so I use BitmapFactory.Options.inSampleSize to request a subsampled (smaller) bitmap. The problem is that the platform does not enforce the exact value of inSampleSize, and I sometimes end up with a bitmap either too small, or still too big for the available memory. From http://developer.android.com/reference/android/graphics/BitmapFactory.Options.html#inSampleSize: Note: the decoder will try to fulfill this request, but the resulting bitmap may have different dimensions that precisely what has been requested. Also, powers of 2 are often faster/easier for the decoder to honor. How should I decode bitmaps from the SD card to get a bitmap of the exact size I need while consuming as little memory as possible to decode it?

• Compile redeclaration error of global variable in C++, but not in C.

  - by coelhudo

  Suppose that I have those three files: a.h //a.h header #include <stdio.h> int int_variable; void a_f() { printf("int_variable: %d\n", int_variable) int_variable++; } b.h //b.h header #include <stdio.h> int int_variable; void b_f() { printf("int_variable: %d\n", int_variable) int_variable++; } main.c //main.c #include "a.h" #include "b.h" int main() { a_f(); b_f(); return 0; } Why compiling in C++ generates redefinition error, but in C doesn't? I am C++ developer, then in C++ makes sense to me, but why in C this is not an error? When I executed the C generated code, the output was: int variable: 0 int variable: 1 Thanks

• Do you know any alternative to NDepend for architects?

  - by ifesdjeen

  Hi! do you know any software similar to NDepend? I've got it just recently, and found it very useful. It helped me a lot, but for now i don't have a possibility to buy a proffessional version. So, is there any alternative (maybe, open-source)? Preferrably, free. But not necessarily. Maybe, with a little bit more fitting price for a single-developer, not a team. Requirements for this software: Build dependency diagrams Retrieve code metrics Display comments coverage (so far)

• SSD and programming

  - by Simon Johnson

  I'm trying to put together a business case for getting every developer in our company an Intel SSD drive. The main codebase contains roughly 400,000 lines of code. My theory is that since the code is scattered about in maybe 1500 files, an SSD drive would be substantially faster for compiles. The logic being that many small reads really punishes the seak-time bottle-neck of a traditional hard-drive. Am I right? Is SSD worth the money in productivity gains by reducing the edit/compile cycle time?

• How to execute a command from with in MSI?

  - by okhalid

  Hi, I have a installation setup with works like this: /exec.exe /some-command This whole setup is located on a shared disk to which my target machine have access to. All i want is to create a small MSI wrapper that basically executes the above command. I don't need to any other fancy things? I looked up on the web; there are tools that create MSI for you but they generate huge amount of other things with them as well. My need is very simple and straight forward. It would be great if some could help me with this issue. Thanks, Omer

• Why darcs instead of git?

  - by Ctrl Alt D-1337

  Using pure functional languages can have a lot of benefits over using impure imperatives but low level systems languages will generally allow you to achieve much greater performance especially when they are imperative because it allows you to specify the exact steps in how the cpu should compute the result. If there is ever list of tools where high performance is an absolute must then I would put source version controls systems right at the top of that list and git achieves this very well but performance is not it's only advantage over many other other types of version control systems anyway. The git team are handling the unsafe c code very well and I never worry about my type system or any other features of the language it is written in so why is it that there is a lot of haskell developers that must use darcs when they will only be using the finished product?

• Creating an installer with WPF forms, packaged files and custom setup actions

  - by RodH257

  I'm trying to create a way of deploying a set of tools (which are add-ins to 3rd party software) to my users. I would like to do the following: User Enters Serial Dlls in their directory structure is extracted to program files a file is copied to a location in ProgramData (this registers my add-ins to the 3rd party application) Online activation for software is performed Can anyone point me into the right direction for this? I had a look at deployment projects in Visual Studio but I'm not sure if they are what I'm after. Main problem is they are ugly, I would like to have a nice WPF installer, and have a more custom experience. But I guess that can be traded off if its going to make things easier. I was thinking, I could just make my own C# project that extracts the files, but I have no idea how to package them up and extract them all as part of one download (like the MSI files that the deployment projects create). Can anyone point me in the right direction?

• Start Activity with an animation

  - by adityad

  I am trying to start an activity with a custom transition animation. The only way I have found out so far to do this (without using onPendingTransition() in the previous activity) is to use a custom theme on the activity and define either activityOpenEnterAnimation, taskOpenEnterAnimation, windowEnterAnimation or windowAnimationStyle to set the animation. But, none of these attributes are working for me. Some experimentation yielded the following results- If I set the windowAnimationStyle attribute to some custom style which defines values for activityOpenEnterAnimation, taskOpenEnterAnimation, windowEnterAnimation or windowAnimationStyle I can get rid of the default transition animation occurring at the start of the activity. It doesn't show the transition animation using the actual value specified but at least the default animation is not shown. According to the reference doc here, http://developer.android.com/reference/android/R.attr.html I should be able to define an animation at the start of the activity using activityOpenEnterAnimation. But no success so far. Any ideas?

• What one-time-password devices are compatible with mod_authn_otp?

  - by netvope

  mod_authn_otp is an Apache web server module for two-factor authentication using one-time passwords (OTP) generated via the HOTP/OATH algorithm defined in RFC 4226. The developer's has listed only one compatible device (the Authenex's A-Key 3600) on their website. If a device is fully compliant with the standard, and it allows you to recover the token ID, it should work. However, without testing, it's hard to tell whether a device is fully compliant. Have you ever tried other devices (software or hardware) with mod_authn_otp (or other open source server-side OTP program)? If yes, please share your experience :)

• How to stop nant exec task putting ( ) around command line

  - by Sam

  I have looked through the nant documentation and sourceforge faq and can't find the answer to this question. The exec task in nant puts ( ) around the command line parameters it generates, so for example this task below would generate: mallow ( -1 ) <exec program="${build.tools.wix}\mallow.exe" workingdir="${build.out.xxx}"> <arg value="-1" /> </exec> The other open source tool I'm using - mallow - cannot handle this. Does anyone know of a way to stop nant putting the ( ) around the arguments? Thanks.

• Embedded computer vision platforms

  - by Egon

  Hi folks, I am planning to start a computer vision based project on a smart phone platform. I know iPhone ( http://niw.at/articles/2009/03/14/using-opencv-on-iphone/en ) and Andriod ( http://github.com/billmccord/OpenCV-Android ) have openCV support. I am interested in knowing how was your experience with the level of integration, support and ease of building good apps on either platform. Also I do want to consider windows phone 7 ( and Zune) as a platform, Are there any Computer Vision libraries for that platform or any good development tools( does Aforgenet work or any other good suggestion) ? Also can you suggest some popular augmented reality apps which uses cutting edge technology ( I am aware of http://www.pranavmistry.com/projects/sixthsense/ ) Thnx in advance!

• What is the most Word-like ASP.NET custom control that you can buy?

  - by rtemp

  We are looking to implement a rich-text box in an ASP.NET application and our requirements are specific to using the "Track Changes" features of Microsoft Word. The closest thing we found in the RadEditor by Telerik. This is a nice control that has a "Track Changes" button and will give you the ability to track the changes from the text in the box to now. It does not let you track your changes from the two previous versions. We have used CVSWeb in the past and the display was not great but it did have the ability (in a web page) to diff two different versions of text (source code in this case). Does anyone have any experience or know of any web-based diff tools that work nicely with a rich-text editor in the web?

• Could you help me understand how to create a C# api by setting the scope of methods, objects, proper

  - by highone

  The answer to this SO question says that you can create an api by exposing methods, objects and .ect by setting their scope to public. http://stackoverflow.com/questions/630971/how-to-start-creating-an-application-api-in-net One of the main things I want to expose is the text of a textbox. Would the best way to do this be to create a public static Text property that is updated by the textbox's textchanged event? Also what would a developer do in order to interact with this text property? Would they add a reference to the program .exe in their program? Please help, I'm quite clueless here. Also was not sure how to word this question, feel free it edit if it is unclear.

• 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!

• Need to debug LINQ simple queries in Visual Studio 2010

  - by maxima120

  I often get in a position when I need to know why my LINQ doesnt work as intended... I use object collections and extensions. I dont want spend more than couple of minutes on it. LINQ supposed to make developer's life easier not harder. I hoped VS 2010 will have it fixed but I now use RC and it still doesnt let me type LINQ and check what is going on... Says as before "Expression cannot contain lambda expressions"... Is there some add-on for Visual Studio so I can quickly and effectively run ad-hoc queries and find out what is going on and where I am wrong?

• What video conferencing software is suitable for communicating with clients?

  - by Nick Retallack

  You're working freelance with several small remote clients and you want to have a meeting via webcam. What do you use? Please consider price, video quality, and minimum hassle for the clients. I'd prefer my clients don't have to pay anything or install anything for it to work. I'm already serving VNC in a Java applet, so something like that would be nice. Skype is awesome, and oovoo looks great, but I'd like to have more than one client on the line at once without them having to pay a subscription too. Something like Ustream.com or Justin.tv would be nice, but it would be better if all parties could talk. Related Questions: Can someone suggest free video conferencing tools

• iPhone keyboard doesn't appear when entering a UITextField

  - by Norm

  This has to be some kind of newbie blunder that I just can’t see, and I’d be grateful for hints as to what to check or where to look. I've followed an iPhone tutorial that has a UITextField, making sure I connected the IBOutlet for the text field, and it seems to compile properly (no errors or warnings). But when I run it under the simulator, and click in the field, I don’t get the keyboard, so I can’t enter anything into the field. I’ve tried searching the site for similar questions, and all I’ve found is a few questions where the developer is trying to set up some complex UI with multiple controllers, and one that seemed to be the same issue, but the original poster simply said that he solved it by starting a new project and porting the code over. I’d like to find an actual solution, so I don’t have to try randomly rebuilding projects when this issue comes up again. Thanks!
