If you like ASP, and want to move to ASP.NET, skip Webforms and learn MVC. |
One way you could do that is to wire up an Application.Load handler in Application.Init, then have that handler unbind itself after running:

Sys.Application.add_load(RunOnce);
}

Another option is that there is no order to types where as numerics and strings can be. Thus a type switch would can't build a binary search tree, just a linear search. |

I would think carefully about this since it may not be a necessary feature.

Remember the [KISS principle][1] (Keep It Simple, Stupid).

Use a hard-coded key to encrypt the generated key before writing it out. Then you can write it anywhere.
Yes you can find the hard-coded key, but so long as you're assuming it's OK to store a symmetric key *anywhere*, it's not less secure. |

Is your type not public, if so, call the overload that takes in a boolean:
Activator.CreateInstance(type, true);
Also, in your first example, see if o is null and if not, print out o.GetType().Name to see what it really is. |
Combining several third-party libraries into one could create more problems for you--for instance, if two of those libraries define a common symbol which your program doesn't use. Now you've got to extract all (or all-but-one) of the instances of the common symbol before you combine the libraries.

What you can do is that after the broadcast have the **clients** initiate the tcp connections. Otherwise you just have to keep a list of all clients and initiate the connections to each client yourself. |

Set based queries are (usually) faster because:
1. They have more information for the query optimizer to optimize

5. Set based logic is the focus of RDBM... |
