I need to write a function that generates an id that is unique for a given machine running a Windows OS.
Currently, I'm using WMI to query various hardware parameters and concatenate them together and hash them to derive the unique id. My question is, what are the suggested parameters I should use?
Currently, I'm ... |

Newer versions of Excel really don't like running macros automatically. If you really want to generate an Excel file and send that to your users, build the full file on the server using the COM interface to Excel, or some libraries that can read/write XLS files, and then send the completed file. |
There are lots of answers here about why a compiler that lets you hide a member function *silently* is a bad idea. But no modern compiler *silently* hides member functions. Even in C++, where it's allowed to do so, there's always a warning about it, and that ought to be enough.
So why require "reintroduce"? The m... |

Have a look at:
http://www.oracle-base.com/articles/misc/ManualOracleUninstall.php
Basically, it comes down to:

With (of course) the requisite reboots thrown in as required ;-) |
Possibly a macro. There are also addins (like ReSharper, which is great but commercial) capable of doing that quickly. |

Yes, there are differences between the two.
Both are anonymous functions and execute in the exact same way. But, the difference between the two is that in the second case scope of the variables is restricted to the anonymous function itself. There is no chance of accidentally adding variables to the global scope.

It's a "quirk" in the way the JVM looks up the zoneinfo file. See [Bug ID 6456628][1].
The easiest workaround is to make /etc/localtime a symlink to the correct zoneinfo file. For Pacific time, the following commands should work:

Can you pull some kind of manufacturer serial number or service tag?
Our shop is a Dell shop, so we use the service tag which is unique to each machine to identify them. I know it can be queried from the BIOS, at least in Linux, but I don't know offhand how to do it in Windows. |
Have you looked at capturing the T-SQL with the DataContext.Log property? If you were able to capure it into an object that also had your tag property you might be able to catalog the SQL your application executes. |

It's a trade off. Strings go into the string pool and when you create multiple identical strings they share the same memory. The designers figured this memory saving technique would work well for the common case, since programs tend to grind over the same strings a lot.
