• Reading from the Registry in ASP.NET

  - by Filip Ekberg

  I have a Library ( DLL ) that has a method with the following: var masterKey = Registry. LocalMachine. OpenSubKey("SOFTWARE\\Microsoft\\Dynamics\\5.0\\"); When running this method in an WinForms applicaiton, masterKey is not null and when running this in asp.net masterKey is null! I've checked the executing user with WindowsIdentity.GetCurrent().Name and the same user is executing both applications. The asp.net application is executed in visual studio ( debug: F5 ) and so is the WinForms application. How come I cannot read the key in asp.net?

• C# WMI Process Differentiation!?

  - by Goober

  Scenario I have a method that returns a list of processes using WMI. If I have 3 processes running (all of which are C# applications) - and they all have THE SAME PROCESS NAME but different command line arguments, how can I differentiate between them If I want to start them or terminate them!? Thoughts As far as I can see, I physically cannot differentiate between them, at least not without having to use the Handle, but that doesn't tell me which one of them got terminated because the others will still sit there with the same name........ ....really stumped, help greatly appreciated!

• hackage package dependencies and future-proof libraries

  - by yairchu

  In the dependencies section of a cabal file: Build-Depends: base >= 3 && < 5, transformers >= 0.2.0 Should I be doing something like Build-Depends: base >= 3 && < 5, transformers >= 0.2.0 && < 0.3.0 (putting upper limits on versions of packages I depend on) or not? I'll use a real example: my "List" package on Hackage (List monad transformer and class) If I don't put the limit - my package could break by a change in "transformers" If I do put the limit - a user that uses "transformers" but is using a newer version of it will not be able to use lift and liftIO with ListT because it's only an instance of these classes of transformers-0.2.x I guess that applications should always put upper limits so that they never break, so this question is only about libraries: Shall I use the upper version limit on dependencies or not?

  I want to capture a photo manually not by using existing camera apps.

Why i dont see the Camera-Screen?

• Core Data vs SQLite 3

  - by Jason Medeiros

  I am already quite familiar with relational databases and have used SQLite (and other databases) in the past. However, Core Data has a certain allure, so I am considering spending some time to learn it for use in my next application. Is there much benefit to using Core Data over SQLite, or vice versa? What are the pros/cons of each? I find it hard to justify the cost of learning Core Data when Apple doesn't use it for many of its flagship applications like Mail.app or iPhoto.app - instead opting for SQLite databases. SQLite is also used extensively on the iPhone. Can those familiar with using both comment on their experience? Perhaps, as with most things, the question is deeper than just using one over the other?

• What is the best method for implementing mouse wheel activity in Delphi VCL forms?

  - by Brian Frost

  As a long time user of Delphi 7, I've rolled my own mouse wheel handling in a few controls but lately I've noticed that some recent applications only need the mouse cursor to be placed over a control (e.g a list box or tree view) for the mouse wheel activity to cause that control to scroll. This feels nice (as opposed to having to click focus a control before it responds to the wheel. Now I've moved to Delphi 2010 I'm wondering what is the 'correct' behavior? And what can I use in Delphi that avoids me having to bodge this with my own solutions now? Thanks.

• Web Application within a Web Site in Visual Studio?

  - by Sean

  Visual Studio allows you to make "Web Sites" and "Web Applications", but, inside a project, can you have one within the other? Say I have my website "www.mysite.com" and I have an application called "BudgetCalculator". One the production server, this is supposed to be located at: www.mysite.com/BudgetCalculator And the BudgetCalculator app contains links back to other parts of the website, like "/page1" and "/page2". However in Visual Studio, when they're listed as two different projects, they're on the same level. When I fire up the debugger for the BudgetCalculator app, those links aren't going to point back to the main website, like they should. Is there a way around this?

• run two apache servers on one computer

  - by harry_T

  I would like to run two XAMPP apache servers and mysql on one Windows computer. My first idea was to run one under directory XAMPP, the other under XAMPP_B. Why you ask? I have two applications that have to be in the "root" directory of localhost. Both servers do not have to be active at same time, so I don't think I will have any conflicts I will have to modify my.cnf in mySQL httpd.conf, apache_start and maybe other config files as well. Or maybe someone can suggest a better way...

• mvc components in codeigniter?

  - by ajsie

  in yii i could have mvc components (acts like an own application). could i have this too in codeigniter? eg. in SYSTEM/APPLICATION have a folder called COMPONENTS and in there i put stand-alone applications that would be a part of the application. components like ADDRESS BOOK, MAIL, TWITTER and so on. every component folder has folders like: models, views, controllers, config etc. so a component model extends the application model which in turn extends system's (code igniter) model. the same goes for view and controller. i've already got a lot of these components which i want to use in codeigniter. is it good idea to place them as i said in SYSTEM/APPLICATION/COMPONENTS or is there best practice for this?

• Dendrogram generated by scipy-cluster does not show

  - by Space_C0wb0y

  I am using scipy-cluster to generate a hierarchical clustering on some data. As a final step of the application, I call the dendrogram function to plot the clustering. I am running on Mac OS X Snow Leopard using the built-in Python 2.6.1 and this matplotlib package. The program runs fine, but at the end the Rocket Ship icon (as I understand, this is the launcher for GUI applications in python) shows up and vanishes immediately without doing anything. Nothing is shown. If I add a 'raw_input' after the call, it just bounces up and down in the dock forever. If I run a simple sample application for matplotlib from the terminal it runs fine. Does anyone have any experiences on this?

• Essential skills of a Data Scientist

  - by harshsinghal

  I would like to know more about the relevant skills in the arsenal of a Data Scientist, and with new technologies coming in every day, how one picks and chooses the essentials. A few ideas germane to this discussion: Knowing SQL and the use of a DB such as MySQL, PostgreSQL was great till the advent of NoSql and non-relational databases. MongoDB, CouchDB etc. are becoming popular to work with web-scale data. Knowing a stats tool like R is enough for analysis, but to create applications one may need to add Java, Python, and such others to the list. Data now comes in the form of text, urls, multi-media to name a few, and there are different paradigms associated with their manipulation. What about cluster computing, parallel computing, the cloud, Amazon EC2, Hadoop ? OLS Regression now has Artificial Neural Networks, Random Forests and other relatively exotic machine learning/data mining algos. for company Thoughts?

• C: Compiling GNU Projects on Windows

  - by Shiftbit

  I would like to port a few applications that I use on Linux to Windows. In particular I have been working on wdiff. A program that compares the differences word by word of two files. Currently I have been able to successfully compile the program on windows through Cygwin. However, I would like to run the program natively on Windows similar to the Project: UnixUtils. How would I go about porting unix utilities on a windows environment? My possible guess it to manually create the ./configure file so that I can create a proper makefile. Am I on the right track? Has anyone had experience porting GNU software to windows?

• Web App Server hardware question. Which configuration?

  - by JBeckton

  I am pricing some new servers and I am not sure which configuration to get. The server will be running some web applications for our company. Some of them are ASP.Net sites and some are ColdFusion. The OS will be Win Server 2008 Web or Standard Edition. Do I need 2 processors or will a single quad core handle it? Xeon multi core Hyperthreading or non Hyperthreading? I am going 64bit so I can go higher than 4 Gigs of Ram. I am shopping at Dell and there are so many options, i do not want to get too much hardware and not use half of it because that would be a waste of money and I do not want to get too little and have to ask for more money to upgrade it later.

• Connecting to multiple firebird Databases via Delphi

  - by Branden

  I am integrating a system with 2 other applications, 1 using a Firebird database whilst the other BIS (using ADO). My delphi application uses Firebird. I need to read data from my database, insert it into both the BIS database and the other application firebird database. I have created seperate data modules for each. Sending data to the ADO works fine, but when writing to the other Firebird DB (my db still open) I get strange errors. I have managed to isolate the problem to the second firebird DB. Small data writes seems fine. The data structures are completly different, so un able to use a synch tool. is there a way to overcome this by using multi threading or seperate memory space each Firebird instance uses?

• Spring.NET. How actively is it being developed/supported?

  - by Bubba88

  I've made my choice for the developement components on the .NET platform: Spring.NET for IoC and NHibernate for data access. But how safe is it? I've heard here on SO (don't remember which post exactly) that Spring.NET is on its way down, cause for example the Java original version is developed by a large number of people; but (they say that) the sole person behind the .NET version is Mr. Mark Pollack. Is that so? And, if so, does it still make sense to count on Spring.NET for my production applications? if you have similar information about NHibernate, I'll appreciate it; though it seems that the latter is actively supported.

• Is there a declarative language for data definitions?

  - by Jekke

  Reading about WPF and thinking about my application's data store at the same time led me to wonder if there are any languages or tools that allow you to define relational data in a declarative way? A shallow Google search suggests no such thing exists. Yet it seems so obviously useful. The kind of tool I have in mind would declaratively describe (at least) entities, relationships and views is a platform-agnostic way that would act as an abstraction layer between data-driven applications and their datastores. Does any such tool exist?

• VS development on FDCC compliant Workstation

  - by paramesh kudlur

  Hi, I have a FDCC compliant workstation with FIPS 140-1 (Level 1) enabled. Now, i cannot run/debug any VS 2005/2008 applications on my machine I get the following error message on my browser Parser Error Message: This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms. the Error points to line no 1 of default.aspx.cs file using system; The only way to successfully debug/run my application is to set the following registry key to 0 HKLM\System\CurrentControlSet\Control\Lsa\fipsalgorithmpolicy I understand that there are some Cryptographic algorithms that are not FIPS compliant on XP SP2 but i am not using cryptography at all. For that matter, the solution contains just default.aspx page with default code in .cs file, and even that fails to run. So my question is why the webpage fails to load, and why the error points to line #1 "using System;" statement? My next question is how can i develop on FIPS compliant locked down maching where i do not have edit rights on registry Thanks kudlur

• bash script to delete old deployments

  - by benjwarner

  I have a directory where our deployments go. A deployment (which is itself a directory) is named in the format: <application-name>_<date> e.g. trader-gui_20091102 There are multiple applications deployed to this same parent directory, so the contents of the parent directory might look something like this: trader-gui_20091106 trader-gui_20091102 trader-gui_20091010 simulator_20091106 simulator_20091102 simulator_20090910 simulator_20090820 I want to write a bash script to clean out all deployments except for the most current of each application. (The most current denoted by the date in the name of the deployment). So running the bash script on the above parent directory would leave: trader-gui_20091106 simulator_20091106 Any help would be appreciated.

• Using Spotlight as the "database" of an application

  - by vicvicvic

  I'm developing an OS X application to organize "things" (as iTunes is to music and iPhoto to photos). Instead of having my own database and index, I'm considering using Spotlight to essentially serve this purpose. Has anyone tried this? Is it wise? The main benefit, as I see it, would be simplicity and avoiding redundancy. It seems a bit wasteful to implement my own index machinery when OS X comes with one built in. I have little experience working with Spotlight, however. From a user's perspective, I do know that it has been slow and imprecise in older versions of OS X. I also have a gut-feeling that since it's aimed at searching the whole filesystem, using it for "local" purposes becomes hackish. Obviously, my applications's index needs to constantly be up-to-date. Can mdimport be used for this?

• Setting up a SQL Membership Provider and attaching the MDF file in Visual Studio 2008

  - by aubreyrhodes

  I'm trying to set up a SQL Membership Provider for an ASP.NET MVC 1.0 and I'm having problems setting up the tables and stored procedures in the database. I've tried attaching both the applications current database and a blank database to my local SQLEXPRESS instance (using SSEUtil) and then running the aspnet_regsql wizard against them. When I detach the mdf file and try to load it in Visual Studio 2008, the data connection in the server explorer shows that the database has no tables or stored procedures. Am I missing a step or something here? I've been having a heap of trouble with compatibility between Visual Studio and SQLEXPRESS.

• How do I export and import application services with say MEF?

  - by John Leidegren

  I'm working with MEF right now, but the answer I'm looking for probably is irrelevant to MEF -- it's all dependency injection -- I'm just using MEF terminology as an example here. Short background story, I read this article over at MSDN with focus on Composite Applications In this figure there's three things, the shell, the application services and the modules. So that's a composite application. What I don't fully get is the application services part. What's the service, what does it look like? How do you expose a service through a module and how do you consume a service from a different module? I'd really like to see some neat small code examples, nothing fancy but something to illustrate how all this comes to life (the application services part).

• I have some questions about building an AIR app for use with a connected projector.

  - by knuckfubuck

  For an app I'm working on, I'd like to have a control panel window and a video output window to use for projecting video with an attached projector. I have built many Flash applications but this will be my first time using AIR so I have some questions. Is it possible to have two seperate windows as part of one AIR application? Can one of the windows (the video output) be in full-screen mode while the other window stays normal? How does AIR do with playing local video? Will there be crashes or choppy playback? Is there a better language option for what I'm trying to accomplish?

• Ruby gems gone after after jruby install

  - by James

  Today I installed jruby by downloading it, extracting it to /home/james/jruby-1.4.0 and adding the following line to .bashrc export JRUBY_HOME=/home/james/jruby-1.4.0 export PATH=$JRUBY_HOME/bin:$PATH And then I installed some jruby gems via jruby -S gem install ... Jruby works fine, but this seemed to have cause two problems: 1) When I try to run a ruby (not jruby) on rails migration, I see: Missing the Rails gem. Please `gem install -v= rails`, update your RAILS_GEM_VERSION setting in config/environment.rb for the Rails version you do have installed, or comment out RAILS_GEM_VERSION to use the latest version installed. 2) when I do gem list --local, I only see the gems that I've installed for jruby. Launching web applications via ruby script/server succeeds without any warnings. Please help.

• Good Perlin noise resources/implementation?

  - by Chumpy

  Are there any good resources out there detailing Perlin noise generation? I understand that most languages have noise generating libraries available, but I'm interested in creating my own for fun/experience. I've already looked at this, which seems pretty popular, but it only gives an in-depth explanation of one dimensional noise. Google searches have been relatively unhelpful so far, as most of them focus on applications instead of how to create a generator. Books and/or websites are welcome, even if their focus is not the generation itself so long as it gives a thorough explanation of an implementation, or at least the concepts involved so I can "discover" my own.
