Visual Basic and Wild Tangent

Hi, I am trying to create some graphics that can be manipulated by the user. To do this I am using 3D library provided by Wild Tangent (www.wildtangent.com)with Visual Basic. I was wondering if anyone was familiar with this as I am keen to get some help and guidance...?
In particular, I have two vertical panels which I would like to rotate about the y-axis using the forward and backwards cursor keys. I know that it involved using:

container1.Setrotation x, y, z, N
where N is the number of degrees

but I don't know how to be able to manipulate this.
Any ideas would be greatly appreciated...Thanks
