In a Windows 2003 domain, I would like to create a SRV record programmatically at install time to advertise to clients where my server is located.

Where should I place unmanaged .dlls in a .NET project using VS2008?
So far I've been placing the dll into the /bin folder because it seems to be the only place it will get loaded when a DllImport'd function is called, but it just doesn't feel right since it's the output folder and it'll probably be wiped after a 'project clean' or 'rebuild all' operation. How should I do this? Thanks in advance. Note: ...

What would be a good replacement for C++ vector in C#?
I'm working on improving my skills in other languages, coming from using c++ as my primary programming language. My current project is hammering down C#.net, as I have heard it is a good in-between language for one who knows both c++ and VB.net.
