Windows 7 - View/Change Power Plan via Registry?

Hello all,
I'm working on a little Visual Basic .NET program that simply changes the power plan based upon the AC power status and battery percentage status (something that Windows 7 should already do...)
Anyway, it's coming along well enough, except that I need to have my program run the 'powercfg' command line utility to change plans. I have yet to find a way for my program to determine which plan is in use.
Is there a registry key that changes the current power plan or something similar, or do I need to play around with grabbing outputs from the command line?

Thanks in advance!

You can find which is the current plan here:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\User\Default\PowerSchemes]
"ActivePowerScheme"="381b4222-f694-41f0-9685-ff5bb260df2e"

GAH!

Thank you!!!
This is going to be a whole lot easier now!

(I can't believe I didn't see that...)

You're welcome.
