Terminating of Activex exe program (out of process )

I have created an activex exe component which prints using crystal activex control a report.
Even after printing and completion that process is still running. How to stop or terminate that process
after my job is completed.?
Please help me out from this.

A VB activeX exe will unload when no external references to it exist and all forms loaded by it are unloaded....check the latter.
