  • log4net - configure using multiple configuration files

    - by Gai
    Hi, I have an application consisting of a host and pluggable modules (plugins). I want to be able to configure log4net for the host and for each of the other modules. Each of them should have its own configuration file and each will log to a different file. Only the host has an App.config file. The plugins have their own config file containing the log4net config sections. Calling XmlConfigurator.Configure from one of the plugins overrides the host's app.config log4net definitions. Is there an easy way to append configurations instead of overriding them? Thanks, Gai.

  • One config file for multiple environments

    - by ho
    I'm currently working with systems that has quite a lot of configuration settings that are environment specific (Dev, UAT, Production). Does anyone have any suggestions for minimizing the changes needed to the config file when moving between environments as well as minimizing the duplication of data in the config file? It's mostly Application settings rather than User settings. The way I'm doing it at the moment is something similar to this: <DevConnectionString>xyz</DevConnectionString> <DevInboundPath>xyz</DevInboundPath> <DevProcessedPath>xyz</DevProcessedPath> <UatConnectionString>xyz</UatConnectionString> <UatInboundPath>xyz</UatInboundPath> <UatProcessedPath>xyz</UatProcessedPath> ... <Environment>Dev</Environment> And then I have a class that reads in the Environment setting via the My.Settings class (it's VB project) and then uses that to decide what other settings to retrieve. This leads to too much duplication though so I'm not sure if it's worth it.

  • LINQ Query Returning Multiple Copies Of First Result

    - by Mike G
    I'm trying to figure out why a simple query in LINQ is returning odd results. I have a view defined in the database. It basically brings together several other tables and does some data munging. It really isn't anything special except for the fact that it deals with a large data set and can be a bit slow. I want to query this view based on a long. Two sample queries below show different queries to this view. var la = Runtime.OmsEntityContext.Positions.Where(p => p.AccountNumber == 12345678).ToList(); var deDa = Runtime.OmsEntityContext.Positions.Where(p => p.AccountNumber == 12345678).Select(p => new { p.AccountNumber, p.SecurityNumber, p.CUSIP }).ToList(); The first one should hand back a List. The second one will be a list of anonymous objects. When I do these queries in entities framework the first one will hand me back a list of results where they're all exactly the same. The second query will hand me back data where the account number is the one that I queried and the other values differ. This seems to do this on a per account number basis, ie if I were to query for one account number or another all the Position objects for one account would have the same value (the first one in the list of Positions for that account) and the second account would have a set of Position objects that all had the same value (again, the first one in it's list of Position objects). I can write SQL that is in effect the same as either of the two EF queries. They both come back with results (say four) that show the correct data, one account number with different securities numbers. Why does this happen??? Is there something that I could be doing wrong so that if I had four results for the first query above that the first record's data also appears in the 2-4th's objects??? I cannot fathom what would/could be causing this. I've searched Google for all kinds of keywords and haven't seen anyone with this issue. We partial class out the Positions class for added functionality (smart object) and some smart properties. There are even some constructors that provide some view model type support. None of this is invoked in the request (I'm 99% sure of this). However, we do this same pattern all over the app. The only thing I can think of is that the mapping in the EDMX is screwy. Is there a way that this would happen if the "primary keys" in the EDMX were not in fact unique given the way the view is constructed? I'm thinking that the dev who imported this model into the EDMX let the designer auto select what would be unique. Any help would give a haggered dev some hope!

  • Mysql: ROLLBACK for multiple queries

    - by Raj
    Hi I have more than three MySql queiries in a PHP script triggered by scheduled task. If a query catch an error, script throw an exception and rollback that Mysql query. It works fine. However if first query works fine, but not 2nd query, throw an exception, it rollback 2nd one but not 1st query. I am using begin_trans(), commit and rollback() for individual queries because Sometimes i need to rollback one query, sometimes all queries. Is there any way to rollback one query or all queries? Thanks in advance UPDATE: I got it working, there was no problem with in begin_trans(), commit and rollback(), the database connection config was different for one query from other queries, crazy code without any comments!!!

  • WCF Multiple Services

    - by David
    Hi, im brand spanking new to WCF and Im trying to understand how to correctly expose my BLL to it. I created my first Resource.svc and IResource.svc Resource.svc [ServiceBehavior] public class Resources : IResources { #region IResources Members public List<Model.Resource> GetAll() { return Repository.Inventory.Resource.GetAll(true); } public List<Model.Resource> GetAllEnabled() { return Repository.Inventory.Resource.GetAllEnabled(true); } #endregion } IResource.cs [ServiceContract] public interface IResources { [OperationContract] List<Model.Resource> GetAll(); [OperationContract] List<Model.Resource> GetAllEnabled(); } So this all works, My windows app can talk to the service and all is great. So I now need to access some information, I have created another .svc file called Project.svc and IProject.cs, this contains the same info as resource (apart from the type is Project) But this now means I have another webservice, surley this is not right!?

  • How to handle multiple openIDs for the same user

    - by Sinan
    For my site I am using a login system much like the one on SO. A user can login with his Facebook, Google (Gmail openID), Twitter account. This question is not about specific oAuth or openID implementations. The question is how to know if the same user logins with different providers. Let me give an example: Bobo comes to site logins to site by clicking on "Login with Facebook". Because this is his first visit we create an account for him. Later Bobo comes to the site. This time he clicks on "Login with Google". So how do I know if this is the same person so I can add this provider to his account instead of creating a new (and duplicate) account. Can I trust solely on email? What is the best way to handle this. How does SO do it? Any ideas?

  • Database frontend for multiple db engines

    - by xeroxed_yeti
    Hey Stackoverflow, yeah it's spring and a lot of things happens to me... Also changing some software things at my computer, because suddenly everything seems to be boring after starting my laptop. I even changed my wallpaper!!! Besides I'm looking for a new database frontend and after using google with serveral queries I didn't find the right software. You have to know, my laptop and me are very very special :) I'm looking for a database frontend which should have following features can access PostgreSQL and MySQL databases can handle schemata overs a nice sql query tool supports an import and export functionality (something like tab separated text files) it for free looks awesome - every time when a college come to my office he must get the feeling: oh boy, this man really knows his job and should get more money! At the moment I used phpmyadmin, phppgadmin, pgadminIII, mysqladmin and dbVisualizer. Furthermore I was a big fan of the aqua datastudio until it became commercial. This tools offers a great variety of functionalities which can simplify programmes live. However, now you have to buy a license...I'm a scientist and money for software is limited =) So it's my first time (question) here at stackoverflow please be cheerful :)

  • Apache/Tomcat configuration to allow multiple incoming DNS served by one app (SAAS)

    - by Shaun F
    Is there a way to setup apache and tomcat so that I can have d1.webapp.com d2.webapp.com d3.webapp.com etc. All hosted by the same tomcat instance without having to add aliases to the HOSTS element in the tomcat config file? I will be allowing new users to have thier own domain when they sign up and it will be a subdomain of the web app. I don't want to keep updating the hosts file for aliases and restarting tomcat though each time a new user signs up.

  • SQL multiple primary keys - localization

    - by Max Malmgren
    I am trying to implement some localization in my database. It looks something like this (prefixes only for clarification) tbl-Categories ID Language Name tbl-Articles ID CategoryID Now, in my tbl-Categories, I want to have primary keys spanning ID and language, so that every combination of ID and language is unique. In tbl-Articles I would like a foreign key to reference ID in categories, but not Language, since I do not want to bind an article to a certain language, only category. Of course, I cannot add a foreign key to part of the primary key. I also cannot have the primary key only on the ID of categories, since then there can only be one language. Having no primary keys disables foreign keys altogether, and that is also not a great solution. Do you have any ideas how I can solve this in an elegant fashion? Thanks.

  • Treat multiple IEnumerable objects as a single IEnumerable

    - by MainMa
    Hi, My question seems to be something easy, but I can't figure it out. Let's say I have a "root" IEnumerable of objects. Each object has IEnumerable of strings. How can I obtain a single IEnumerable of those strings? A possible solution is to do: public IEnumerable<string> DoExample() { foreach (var c in rootSetOfObjects) { foreach (var n in c.childSetOfStrings) { yield return n; } } } But maybe there is a magic solution with Linq?

    I have a mac and a macbook, and one iPhone device and want to develop on both systems. My enrollment type is individual. How am I able to install the developer certificate and provisioning profiles on both machines? On the macbook it says 'a valid signing identity matching this profile could not be found in your keychain'. In my keychain I have a 'green status' for my developer certificate and in the xcode organizer for my device as well.

  • MySQL: Storage of multiple text fields for a record

    - by Tom
    An inexperienced question: I need to store about 10 unknown-length text fields per record into a MySQL table. I expect no more than 50K rows in total for this table but speed is important. The database actions will be solely SELECTs for all practical purposes. I'm using InnoDB. In other words: id | text1 | text2 | text3 | .... | text10 As I understand that MySQL will store the text elsewhere and use its own indicators on the table itself, I'm wondering whether there's any fundamental performance implications that I should be worrying about given the way the data is stored? (i.e. several "sub-fetches" from the table). Thank you.

  • Django multiple generic_inline_formset in a view

    - by Can Burak Cilingir
    We have a bunch of formsets: EmailAddressInlineFormSet = generic_inlineformset_factory( EmailAddress, extra=1, exclude=["created_by","last_modified_by"]) emailaddressformset = EmailAddressInlineFormSet( instance=person, prefix="emailaddress") # [ more definitions ] and, in the view, we process them as: emailaddressformset = EmailAddressInlineFormSet( request.POST, instance=person, prefix="emailaddress") # [ more definitions ] So, nothing fancy or unordinary. The unfortunate or unordinary fact is, we have 15 of these formsets, one for email addresses, other for phone numbers etc. so the view code is ugly and not-so-manageable. What would be the most unhackish way to handle this number of formsets in a single view? At the end -i guess- I'm looking for a class or a functionality like multiple_generic_inline_formset and open to all kind of suggestions or discussions.

  • Access one database from multiple ORMs :: Caching issue

    - by kaptan
    I know this is not a good idea and the best would be to let the applications talk Web Services. But I have a situation where the legacy application is accessing a database with an ORM and I need to access the same database from the new .net application using Fluent nHibernate. So the question is what problems this will make and how to solve them? I guess the main issue is the caching. I need to disable the caching on one of the applications (which would be the new app). So how can I disable caching in nHibernate? Is there anything else that should be careful about?
