You may not be able to auto disable the Wireless Adapter but you can configure an "interface metric" in Windows. If you make the Wireless interface a lower priority metric it should accomplish what you want. Please note this is a different metric than a "gateway metric", which can also be configured in Windows.

You know, it's funny, because as soon as I hit Send, I looked at the laptop I was building out next to me and I couldn't find that option either. Maybe I was lying and it's only Dell WiFi cards, but I was sure it was Intel. You're looking in the right place though, the Advanced tab is where I saw it, or at least, THOUGHT I saw it...
Confirmed! It looks like it's Dell cards that support this feature :( http://support.dell.com/support/edocs/network/p70008/en/props.htm#toc_70

I'm quite interested in this capability. I've got a Thinkpad with Intel drivers for both the wired and wireless adapters (PRO/1000, PRO/Wireless
3945ABG) and I don't see such a setting. On the chance I'm missing it,
would you describe in more detail where it is? I'm guessing it's under the
Advanced tab as a Property, but I don't see such a setting.
Thanks -- this sounds interesting.

Depending on the drivers on the system, you can specify that a wired connection disables the wifi. I've seen this mostly on Intel drivers, but some Dell cards support this as well I believe. Since I almost never install the full [crappy] software package that comes with wifi drivers, you can look for this setting in Device Manager, under the Properties for the wifi interface.

Yeah, good luck with that. You can see the route metrics by running "route print" (at least under XP), and you can add/delete routes using the "route"
command, but I don't know where to set default metrics for new connections.
Generally, the wired interface will have a better metric, but I have seen occasions where my browser traffic will prefer the wireless interface, while other non-browser connections remain on the wired link. I generally just kill the wireless when I'm docked.
