• XBAP usage and maturity issues

  - by Yonatan Karni

  we're considering migrating our UI to XBAP. we've chosen XBAP despite knowing the clients must have .net pre-installed, since we're not targeting the masses but rather IT professionals in the corporate environment, and it's a way to preserve our investment (in a WPF based UI in a client-server architecture) and enjoy web deployment. however, we are concerned about the maturity of the platform/architecture and it's adoption. do you know of any commercial applications out there using XBAP, and do you have any experience using it? can you elaborate on that experience? also, as @Murph suggested, can you think of strong reasons to prefer clickOnce over XBAP (or the other way around)?

• What useful GDB scripts have you used/written?

  - by nik

  People use gdb on and off for debugging, of course there are lots of other debugging tools across the varied OSes, with and without GUI and, maybe other fancy IDE features. I would like to know what useful gdb scripts you have written and liked. While, I do not mean a dump of commands in a something.gdb file that you source to pull out a bunch of data, if that made your day, go ahead and talk about it. Lets think conditional processing, control loops and functions written for more elegant and refined programming to debug and, maybe even for whitebox testing Things get interesting when you start debugging remote systems (say, over a serial/ethernet interface) And, what if the target is a multi-processor (and, multithreaded) system Let me put a simple case as an example... Say, A script that traversed serially over entries to locate a bad entry in a large hash-table that is implemented on an embedded platform. That helped me debug a broken hash-table once.

• Web-based map authoring with ArcGIS Server?

  - by nw

  I'm embarking on a project in which users will author, save, and share their own maps over the web. We will provide them with a large number of feature classes, but users will effectively author their own maps, map symbologies, etc. Furthermore, they will create and edit their own feature classes, which they can both map and share with other users. The model for AGS map services seems to be: author a map in ArcMap, save an MXD/MSD, publish. I'm struggling to understand how this can help us build a dynamic web mapping platform as described above. Can anyone offer some tips on how to go about it?

• MembershipProvider, IPrincipal, IIdentity?

  - by MRFerocius

  Hello guys; I have a conceptual question... I am making an Intranet application (Web platform) for a company. I have a SQL Server DB with these tables: Users (userID, userName, userPass, roleID) Roles (roleID, roleName) Pages (pageID, pageURL) RolesXPages(pageID, roleID) How is the best way to create a structure to store all this information while the user navigates the site, I mean, on the thread I should be able to check his role, his pages (the ones he can access) I have been reading and there is a lot of stuff there where Im confused, I saw the MembershipProvider, IPrincipal, IIdentity, etc classes but Im not sure what should be the best one for me. Any thoughts... Thanks in advance! Edit: Everytime gets more confusing... I just want to handle those structures at runtime and be able to mantain state during page callbacks or changing pages...

• Continuous integration with ClearCase and long-updating snapshot views

  - by Yulia Rogovaya

  Hi, I need to set up a continuous integration system. We use ClearCase version control and only snapshot views due to platform restrictions. I have tried setting up Hudson and Luntbuild. They both show the same behaviour. In a view, we have lots of libraries that are used for build but are strictly read-only. The CI system executes cleartool lshistory and finds a change in the VCS. After that, it executes cleartool setcs, which causes update of the view. This can take about half an hour, which is very undesirable for CI. Why wouldn't it update only the changed elements, which were previously obtained by cleartool lshistory? Is there a CI system that can do this?

• Should I use WPF or ASP.NET for my next Web Application development?

  - by gap

  We have a web application that has been built using MySQL / PHP / Javascript+JQuery, with server-side HTML generation. The problem is that of the 10 software developers that work for the company, none are PHP experts (we're all .NET / C# developers). I need to make a recommendation to my management team on which technologies to use as the platform for the next generation of web application products. I want to leverage the .NET / C# expertise which the company has and is otherwise building, and so am inclined to recommend some Microsoft technologies. We don't want a client-side plugin, and we don't need flashy animations/multimedia, so I'm ruling out Silverlight. Is WPF ready for primetime? Is ASP.NET deprecated by WPF? How do I choose between these two technologies? Big Question, I know... I can refine it based on your comments if necessary. Thanks for taking the time.

• Get seconds since epoch in any POSIX compliant shell

  - by mattbh

  I'd like to know if there's a way to get the number of seconds since the UNIX epoch in any POSIX compliant shell, without resorting to non-POSIX languages like perl, or using non-POSIX extensions like GNU awk's strftime function. Here are some solutions I've already ruled out... date +%s // Doesn't work on Solaris I've seen some shell scripts suggested before, which parse the output of date then derive seconds from the formatted gregorian calendar date, but they don't seem to take details like leap seconds into account. GNU awk has the strftime function, but this isn't available in standard awk. I could write a small C program which calls the time function, but the binary would be specific to a particular architecture. Is there a cross platform way to do this using only POSIX compliant tools? I'm tempted to give up and accept a dependency on perl, which is at least widely deployed. perl -e 'print time' // Cheating (non-POSIX), but should work on most platforms

• phantom error "error parsing XML: unbound prefix"

  - by Brad Hein

  The error "error parsing XML: unbound prefix" shows up on my main layout: main.xml when I first open Eclipse. To make the error go away, all I have to do is make a modification to the file, then undo it, then hit save (have to make a change in order to be able to save file and thus trigger the new syntax check). My environment is: Fedora Eclipse Platform Version: 3.4.2 Based on build id: 20090211-1700 My target is Android API level 5. The first time I saw the error I spent a long time trying to track down "the problem" but later realized there isn't really a problem, it's just a phantom error. Screenshot: http://i50.tinypic.com/2i89iee.jpg Who should I report this to?

• Using a DataSet instead of custom business entities in soa and n-tier architecture

  - by kathy

  I’m working on a large and a high volume transactional enterprise application which has been designed using n-tire application architecture .And it was developed in the .NET platform utilizing C#,VB.NEt, Framework 3.5, ObjectDataSources, DataSet, WCF, asp.net update panel, JavaScript ,JSON, 3rd Party tools. The application is supposed to accomplish a really scalable / easily maintained / robust application / integrations, and to make sure that my services are created using a format that can be understood by other systems. The problem is, this application is about 70% complete but now I was wondering if the following would cause us future issues, I’m using a DataSet and a DataTable to (get /set) the data (form /to) the stored procedure in the database using the ObjectDataSources and was wondering if this would prevent my application from achieving the above goals. Actually, I am not anti-OO. I write lots of classes for different purposes, but I didn’t use the entity objects(custom business entities) instead of the previous way because I have a large database that may contain 50 tables and I was just afraid to create entities for each table and then in the future if I need to change the schema of the database, it might cause a huge affect on the application ?

• Can't finish Eclipse Plug-in Project Wizard when choosing RCP

  - by Jens Schauder

  I'm trying create a RCP Application with Eclipse, but I can't get past the 'Content' screen of the New Plug-in Project Wizard. When I select 'yes' for "Rich Client Application, Would you like to create a rich client application" it disables the Next and the Finish Button. I first thought it is due to my target platform which is Eclipse 3.2, but changing that doesn't make a difference. On the top of the screen only one task is displayed (now warnings about missing or incompatible information): Enter the data required to generate the plug-in My Eclipse Version is 3.5 Any ideas? Since it was asked. A screenshot can be found here: http://www.flickr.com/photos/jensschauder/4535101973/

• How to resume repo sync

  - by webgenius

  Can anyone please mention how to resume the sync command? I followed the following steps: $ repo init -u git://git.omapzoom.org/platform/omapmanifest.git -b eclair $ repo sync The sync took more than 6 hours and I had to terminate the sync myself due to shortgae of bandwidth. Is there any way I can resume the sync from the previous session? I can see that the following folders are created: bionic.git bootable build.git cts.git and many more.... I have access to free bandwidth only for 6 hours in a day, and I have to do the sync within this time. Any help is really appreciated.

• Is there anything RAD comparible to VCL?

  - by mawg

  After years in embedded programmking, I have to develop a windows app. I dug out my old C++ builder and Delphi. These are great and the latest version costs over $1k, so I won't be going there. What I prarticularly like is the VCL (visual component library) which let's me code my own components and share them with others, plus the thousands of existing 3rd party components. I noticed that there is now also a RAD PHP form Borland too. I realzie that MSVC, QT, NetBEans, etc are good enough IDEs for RAD, _BUT_ does anything offer the ease of the Borland products for developing additional components - and does anything else have thousands to choose from? PC based? Cross-platform is good. Browser based? Free is always good ;-) I don't particularly care about the programming language.

• Building v8 without JIT

  - by rames

  Hello, I would like to run some tests on v8 with and without JIT to compare performances. I know JIT will improve my average speed performance, but it would be nice for me to have some actual more detailed tests results as I want to work with mobile platforms. I haven't found how to enable or disable JIT like it exists on Squirrelfish (cf. ENABLE_JIT in JavaScriptCore/wtf/Platform.h). Does somebody knows how to do that with v8? Thanks. Alexandre

• Analysing a Visual Foxpro application to derive requirements. Tools/approaches/practices?

  - by Kabeer

  Hello. In an upcoming project I am supposed to re-engineer a huge application built on Visual Foxpro into a web-application. The target platform is .Net. The application from the end-users' perspective is very complex (complex forms, reports, navigation, etc). The sorry state is that there are no documents available from which I can derive, business processes, business rules, work-flows, validations, application state, etc. I can gather some requirements from end-users but it cannot be complete from any perspective. Maneuvering through the code would be tedious & time consuming, given the millions of lines of code. Therefore I am looking for a tool that can help me in code analysis. My googling attempt didn't help me at least for a Visual Foxpro code base. Besides, I will appreciate if someone can share processes/approaches/techniques to establish the requirements as far as possible. BTW, this link didn't quite help.

• How to convert TM-2 degree coordinate to lat lon on Android?

  - by Victor Lin

  I am writing a program that convert TM-2 degree to lat/lon on Android, but I can't find formula for that. I do find some example on internet, but most of them are convert with open source library, that I can't use on Android platform. I also find a java class that do convert from UTM to lat lon, but it seems no suitable for TM 2 degreen coordinate system. So my question is: how do I convert TM 2 degree coordinate to lat/lon? Where can I find formula?

• Which language/framework to use for this desktop internet application?

  - by Karsten

  I'd like to experiment with a new language/framework to work on some desktop tools for myself, which will do tasks related to internet services. I.e. i'd like to to monitor some of my servers for http or icmp response, also parse xml responses. I have experience with php, lua, mysql, and basic knowledge of java and c++. I'm also interested in exploring multithreading for this, background tasks and a responsive gui do need that as i have read. Being a private project, i certainly want to learn something new, but i don't have that much free time. The question for you would be which language and what framework to choose that could help me with this tasks: lightweight + fast gui (windows only would be ok, platform-independent even better) network/socket support, html module would be appreciated htmlview support xml "parsing" support (xpath or something like the phpish DOMDocument class) threading support Free software would be nice, but paying some bucks won't hurt me if it really helps the case.

• Creating a Stack Overflow notifier

  - by Trey

  I could not find a Stack Overflow notifier Android app so I am planning on making one. I hope that my app will serve a similar purpose as the Stack Overflow Notifier Chrome extension. This will be my first Android app so I am still unfamiliar with the platform. My main concern when creating this app is, what is the proper way to access the user's Recent Activity page? I thought of two different approaches but I'm not sure how to implement either one: Make the user login to Stack Overflow through the Browser application or an embedded browser and scrape their recent activity page occasionally for updates. Ask the user for their username and password and forward this information to Stack Overflow for authentication, storing cookies somehow to keep the session active. I think Astrid uses something similar to the first approach, but I haven't been able to figure it out yet from skimming their code. What is the correct way to handle a notification application like this that requires session management?

• 32-bit oracle 10g client to 64-bit oracle 10g server

  - by Dakshin

  Due to a 3rd party application's requirement, I may be forced to use 32-bit client of Oracle 10gR2 on the application server to connect to a 64-bit DB server oracle 10gR2 (10.2.0.4.0 - 64bit;another box). The OS is SUSE Linux ver 10. Platform is x86. There are no problems connecting to 64-bit DB server via 32-bit client. I have tested this. Does this result in performance degradation? Does Oracle or anyone else has any recommendations about this kind of scenario? Searched the net without much gain. Please help. Thanks.

• How to kill msvsmon.exe when finished remote debugging?

  - by dferraro

  Hi, We are a .NET LOB shop using MS CRM as our CRM platform. To this end, we many times a day during development phases are using remote debugging due to 2 connection limit to the server. We are able to setup remote debugging without logging onto the machine by using PsExec. This works great - but how the heck do we kill the remote debugger for that user, once we are finished debugging? In fact, not even sure how to kill the remote debugger in general, even when manually opening it... without remoting into server and using task manager, or keeping the server open and doing File-Exit on the debugger. Any advice?

• How to complie x64 asp.net website?

  - by Eran Betzalel

  I'm trying to compile (using Visual Studio) an ASP.Net website with the Chilkat library. The compilation fails due to this error: Could not load file or assembly 'ChilkatDotNet2, Version=9.0.8.0, Culture=neutral, PublicKeyToken=eb5fc1fc52ef09bd' or one of its dependencies. An attempt was made to load a program with an incorrect format. I've been told that this error occurs because of platform noncompliance. The weird thing is that although the compilation fails, the site works once accessed from a browser. My theory is that the IIS compilation uses csc.exe compiler from the Framework64 (64 bit) folder while the Visual Studio uses csc.exe compiler from the Framework (32 bit) folder. If this is acually it, how can I configure my Visual studio to run with the 64 bit compiler for ASP.Net sites? This is my current development configuration: Windows 7 (x64). Visual Studio 2008 Pro (x86 of course...). Chilkat library (x64) IIS/Asp.net (x64).

• Do I really need cmake for build automation?

  - by PMiller

  I'm currently investigating cmake to allow automatic building on the Win32 platform. For all runtimes and libraries I'd like to build, Visual Studio (2008/2010) projects do allready exist. I've come across cmake, but I'm unsure if I really need it. As the documentation says, cmake generates VS projects and they then can be built e.g. using MSBuild. As the projects itself allready do exist (and build nicely via the IDE or MSBuild on the cmd line), what do I need and use cmake for? Just for directory/project folder traversal? Build failure reporting? Regards, Paul

• What technologies should I focus on to work as a developer in Japan?

  - by Atomiton

  I'm thinking of one day moving to Japan and I was wondering if anyone here has any experience working there. I'm curious as to what languages/technology are popular there for web development and software development. I have heard Ruby is/was strong there due to its founder being Japanese. What would you recommend someone focus on if they wanted to work as a developer in Japan? I have heard Microsoft has a strong base in Japan, but my guess is that whatever platform has supported unicode or Shift-JIS the best would be the strongest.

• producing pixel-identical images of text between Sun Java and OpenJDK

  - by yuvi

  My release script produces images of the version number to save me the trouble of manually going into the MoinMoin wiki software and changing it by hand for each release. Unfortunately, since the fonts look a little different on each platform's JVM, the result is ugly. I solved the the font inconsistency by using Lucide Sans (comes with every Java system). (Loading Fonts from TTF files was another option, but was buggy on Mac Java). The result is much better, producing the exact same image on Mac/Windows (), but a slightly different one on OpenJDK (). I believe this is caused by OpenJDK having a different font rendering system (as opposed to different fonts). Is there any way I can get all three of my target platforms (Sun Windows, Mac, OpenJDK Linux) to produce images of text that look identical?
