  c# inheritance
  Knowing that C# doesn’t support multiple inheritance, is it considered bad form to write a utility base class?Some initial thoughts:I could create an interface and a concretion, but then the implementation isn’t portable Should the developer need to extend the class in say, a decorator pattern, they could implement this new class and inherit the base class in their new classEDIT:N.B. I’m not talking about vanilla inheritance here e.g. poodle<–dog<–mammal<–animalMore this sort of thin

  c# coding-style coding-standards teamwork
  I have one one software system which allows developers to specify an ID or name to create NodeReferences. Both work fine, but ID’s are not guaranteed to be the same across different environments. I’ve tried in documentation and in conversations to stress that ID’s should not be hard coded (since they will break when deployed to a different environments), but some developers are still using them. This works only in dev environment:var level = LevelReference.ById(20); var node = NodeReference.ByNa

  c# .net git debugging
  When our application doesn’t work the way we expect it to (e.g. throws exceptions etc.), I usually insert a lot of debug code at certain points in the application in order to get a better overview of what exactly is going on, what the values for certain objects are, to better trace where this error is triggered from. Then I send a new installer to the user(s) that are having the problem and if the problem is triggered again I look at the logs and see what they say.But I don’t want all this debug

  c# oracle
  I have an Oracle server running on Windows Server. When an INSERT statement runs I receive an Oracle Ora-00603 error. The insert statement just tries to insert a BLOB into a table. I searched the error specification on Google and found that perhaps there are network connection issues. The suggested action is to log in again to Oracle Server. I followed this tip, however I still receive the same error.The error I receive is the following:ora-00603: ORACLE server session terminated by fatal error

  I saw this question “Is this implementation of an Asynchronous TCP/UDP Server correct” and it is very similar to what I want to do but it goes about it in a different way so I am wondering if anyone would mind doing some constructive critism on my method please.I’m looking for any feedback along the lines of “when x happens your server will fall over because of y” or something like that.My intention is that the server should log out errors that happen and raise an event when it has data.

  c#
  I have two quite mutually exclusive desires – detailed logs and keeping my code clean. It appears that you can only get either of these. By “logging” I mean logging and not tracing, so AOP adepts wouldn’t appreciate it.What I want to have is real description of action my program does, why it does these actions and so forth. For instance, ‘failures’ could either be real failures like ‘fatal errors’, or absolutely normal behavior depending on context: I don’t like to check whether or not file exis

  database asp.net oracle exception-handling asynchronous-programming
  I have a product with two separate applications. The core of the product lives in the database (oracle) and runs according to a schedule. The other is a client application (currently ASP.NET MVC3) used to manage the database application. There are three levels of validation going on; client, server-side, and database before the client data is saved to the database. However, there are cases where pieces of the data set are currently valid but could become invalid at some point in the future. I

  cryptography ssl iis
  In SSL if the handshake is not succesful, does it always end with a handshake alert? Or are there other ways to finish the SSL connection (acceptable by standard). I am asking this, because in an HTTPS server configured to require client authentication, if the client does not send a certificate, I see (via network packets) a TLS Finished message from server to client; I was expecting an alert.

  c# asp.net visual-studio web-services iis
  I’m using a native DLL (FastImage.dll) in a C# ASP.NET Web Service that sometimes locks (can’t delete it—says access denied); this requires stopping IIS to delete the DLL. The inability to delete this DLL in the bin folder of my published Web Service prevents me from publishing successfully (even though it thinks it published successfully!), which makes development and fixing the bug difficult (especially when it just happily runs old code since my changes may not be reflected on the server!).
