I tried regasm.exe and it successfully unreg the Assembly-based COM class. Thanks.

>>>Hi William,
>>>just create a new .Net solution, add a "Class Library" project to the solution.
>>>In the project properties check the "Register for COM interop" checkbox, add code to the classes, for example:
>>>
>>>Public Class Class1
>>> Public Function hello()
>>> Return "hello"
>>> End Function
>>>End Class

>>>Generate the solution, switch to VFP, in the command window type:
>>>
>>>xx=CREATEOBJECT("theprojectname.class1")
>>>?xx.hello

>>>you are done.
