Button click emulation in Win CE

Gert
I would like to test my Software under Win CE 6.0. This Programm is in
Visual Studio 2008 programmed.
This software has ten buttons. I must click each buttons from 1 up 10 every
20 secconds. 
Do you have any tool, that does a script to emulation button clicks ?
If I start this script, it does buttons click on my software.
