Background: Our C# application generates and executes queries to several types of databases (Oracle, SQL Server, MySQL), but a requirement came up to also apply them to a proprietary file format. The namespace used until now is System.Data.Common. The queries we need to apply are non-trivial (nested SELECTs, aliases in FROM, substring...
.NET 3.5, I've got some classes which stores up to 1MB of strings. Even though I need the object for a really long time I don't need to store the string for a long time. How can I truly remove the string from memory without disposing the parent object. Is it a good practice to use "myString = null" in this case? or shall wrap it in a ...
I need to specify my T4 to use C# 4.0, to render my tt files? I tried using <#@ template language="C#v4.0" debug="true" #> But when I use a dynamic variable, like this dynamic x=10; Write(x.ToString()); I'm getting these errors Error 2 Compiling transformation: Predefined type 'Microsoft.CSharp.RuntimeBinder.CSharpSetMemberBind...

We are required to use a 3rd party ActiveX control. The only issue is, the layer in our software is a business layer and has no access to a window or form. It also runs on separate threads (and should work from any thread) that are not STA. Rather than breaking our separation of UI from business logic, we used this workaround to make ...

I have a C# .NET 2.0 application that loads legacy VB6 modules (which we have not converted yet) which are ActiveX controls (.ocx files) the application loads these from the main C# .NET form via interops. Since service pack 2 for .NET 2.0 our users have been getting random errors where the application will throw a "Windowless ActiveX c...
I know you can perform a 'Find All References' on a function and you can determine if it is being used anywhere, but is there a tool that will go through all of my functions and highlight any that are not called anywhere in the code? ...
I just started playing with Linq to SQL the other day and was curious if I should use it in up coming projects. I know it will save me tons of developement time. I have seen many similar questions out there on the subject but I have a few more specific questions. Is there anything wrong with inheriting the classes generated in the ...

I've got a set of business/domain classes (for a calendar) that are going to be exposed in an internally-public API. In the same API, there are data objects that directly mirror the underlying database structure (NHibernate mapping, but that's unimportant). What I need to do is build typed collections of those objects, so the days on th...

Hi I have two assemblies, A and B, where A depends on B. I'm trying to obfuscate both of them together, i.e. in a way it doesn't break the app with the babel obfuscator. Is there a way to do that? Apparently this obfuscator doesn't handle multiple assemblies. If that's an issue, which other .NET obfuscator- that handles multiple assem...
I'm looking to do the same as in this question here, however I am developing in a .NET class library, referencing the Primary Interop Assemblies. The item returned from the dialog box collection when I do this wordApp.Dialogs[WdWordDialog.wdDialogFilePrintSetup] does not expose properties such as Printer and DoNotSetAsSysDefault. Doe...

The collection is a Skip list and those of you familiar with it know that for every node inserted I need to generate a new height that is <= CurrentMaxHeight+1, here's the code that I'm using to d...
I'm familiar with unit testing, but am still learning about mocks and mocking frameworks. I get the ideas (I think), but the syntax still seems a little foreign. I'm considering creating some T4 templates that automatically generate mock implementations of interfaces and classes. Using a combination of generics and extension methods, thi...
