On the web site msdn.microsoft.com/scripting/ Microsoft has a Active-X
control that can run VBScript (or any Active-X Scripting language)
from inside a Visual Basic application. It is free. Although its focus
has been web development, it can be used in any application.


This might save you some development time or give you some ideas on
how Microsoft did it. It would allow dynamic creation of code that
could be executed at run time.
