Greg,

>Does any have a piece of code or article that demostrates how to stop a COM+ or MTS package from running. I need it as part of by automatic build process.

Randy Brown's paper on VFP6 and MTS (1998) has a section near the end about "Automating MTS Administration" and goes into some detail, including using project hooks. I haven't read it in detail in a while, but it might have what you're looking for.
