Tips on walking through unfamiliar code or info on tools that help the process?
I would love tips on how to walk unfamiliar code with many objects. Before OOP this was still a difficult thing and I would do it with listings and have tabs and 8 fingers holding my place.

I am using CodeDom to generate dynamic code based on user values. One of those values controls what the name of the class I'm generating is. I know I could sterilize the name based on language rules about valid class names using regular expressions, but I'd like to know if there is a specific method built into the framework to validate a...
Are properties accessed by fields still lazy-loaded?
I'm using the field.camelcase in my mapping files to setting things like collections, dependant entities, etc. and exposing the collections as readonly arrays. I know the access strategy does not affect the lazy loading, I just want confirm that this will still be cached: private ISet<AttributeValue> attributes; public virtual Attribu...
Built in unit-testing in VS
Hi all, I'm looking for advice on the built-in unit testing feature provided in VS08.

Windsor Container: Registering things in Code vs Xml
From what I've read about Windsor/Microkernel it is in theory possible to do everything that you can do using xml files with code. As a matter of fact - and please correct me if I'm wrong - it seems like the major contribution of the Windsor layer is to add xml configuration for things Microkernel can already do. However, I have been ...

Baseline snaplines in custom Winforms controls
I have a custom user control with a textbox on it and I'd like to expose the baseline (of the text in the textbox) snapline outside of the custom control. I know that you create a designer (inherited from ControlDesigner) and override SnapLines to get access to the snaplines, but I'm wondering how to get the text baseline of a control t...
Want to write to a file, but may have potentially multiple writers at once, need to lock.
Hi, In a asp.net web application, I want to write to a file. This function will first get data from the database, and then write out the flat file.

Do you generate code? If so, what do you use and what do you generate?
I've used MyGeneration, and I love it for generating code that uses Data Access Applicaiton Blocks from Microsoft for my Data Access Layer, and keeping my database concepts in sync with the domain I am modeling. Although, it took a steeper than expected learning curve one weekend to make it productive. I'm wondering what others are doi...
