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

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

ssl windows certificates .net
I have written an application (in C#) to communicate with one of our customers via a web service. Our customer requires us to use bi-directional SSL. The customer has sent us their certificate (in the form of a .p7b file). The client certificate was provided to me in the form of a .cer file.I’ve installed the certificates and in the program I use the HttpWebRequest class and add the client certificate to the ClientCertificates collection.When I run the program I get an exception:System.Net.We

.net sql-server
I’ve recently started receiving this error: “Internal connection fatal error” from my application. The error occurs randomly. When it happens my application is unusable for the next few minutes. After careful analysis of the error I’ve concluded that this error happens in only one method within my application. This method fires a series of simple ordinary SQL queries but it does involve multithreading however all threads should be disposed before this block of code. The error happens always on a

Duplicate of: Getting assemblies to show in the .NET tab of Add ReferenceSo, I’m using Visual C# 2008 Express Edition and I’ve just been on a bit of a detour as I found out that my assumption that the .NET tab of the ‘Add Reference’ dialog lists the contents of the GAC was incorrect. This was a bit of a problem for me as the assembly that I wanted to reference from my project was only available in the GAC.

I’m trying to deploy some sort of framework and therefore need to register some assemblies in the GAC.The interesting part is: These GAC assemblies should only be used by the framework developer, the client apps should not use these GAC assemblies but the ones in their local directories (the GAC assemblies could be of a different version, most likely higher).I’ve already found and tried the app.config setting but it seems to be ignored by the client app (latest .NET runtime installed is 3.5).An

c# assemblies reference gac activereports
I have a project where I simultaneously must use reports built in ActiveReports 2 and ActiveReports 6. Overall, it works ok, but some of the helper assemblies use the same name. For instance, to be able to export to PDF, both versions use an assembly called ActiveReports.PdfExport.dll. The corresponding assemblies are different, of course.Note that I don’t access the ActiveReports.PdfExport.dll directly – this is handled by the ActiveReports runtime.I can’t find a way to include both of them
