Right now, I have a method that takes a Trader as an argument and stores it 50 or so times in the vector. I am having problems because storing the same object 50 times is just storing 50 references of the ...
Can you point me to a good reference book for MySQL? I'm an experienced database programmer, but I'm new to MySQL, so I need a book where I can look up specific things and get quick (short) answers (preferably with clear examples). It needs to explain MySQL-specific things, not standard SQL. I don't want a wordy book explaining the...

How can we access and reference classes and variables in different pages in ASP.NET? In version 2003, it was straight forward, just reference the class name of the page and the whole page becomes at your command, but with Websites instead of Web Applications, that does not seem to be the case.

Why does constructor ORDER matter in VB.Net? I am building a .Net type library which is meant to wrap an underlying COM library completely so that the consumers of the API can pretend to use a nice .Net library with .Net collections and whatnot instead of a COM library. Currently most of my classes are just 1 to 1 wrappers built using R...
There are already two questions about F#/functional snippets. However what I'm looking for here are useful snippets, little 'helper' functions that are reusable. Or obscure but nifty patterns that you can never quite remember. Something like: open System.IO let rec visitor dir filter= seq { yield! Directory.GetFiles(dir, filter)...

I'm trying to reconcile the various Adobe AIR HTML guides, and am totally lost. I want to do something with a socket. Some general guides on the topic here and here refer to Air.Socket(); But the supposedly Adobe AIR HTML reference looks like it's not even JavaScript and it references a namespace (window.runtime.flash.net.Socket) that ...
Hi, We have a multi-tiered application using CSLA Business Objects and NHibernate ORM. In our Business Objects, we hold our collection data members as ICollection<T>, and in our object mapping files we define them as <set>s. Since NHibernate uses its own concrete types to fetch these collections, we have a problem when these collection...
