Vista - Disable the visual themes for an exec

Hello all,

I am trying to find a way to disable the visual themes for an executable on
vista using powershell. What I would like to do is have a function that will
take the exec as a parameter and change the property. But I need to do this
as a post biuld task inside Visual Studio as the exec is recreated after each
build.

Does anyone have a direction for me to look, or provide an example.

Thanks,
Glenn.
