I'm finally back to working on testing the support for ActiveX
licensing in my scripting language. I've traced through the ATL code
and my license string seems to be getting processed correctly.
However, it is being rejected when it is passed to IClassFactory2's
CreateInstaceLic method on line 119 of AtlHost.h. I think I must
have the format of the license string incorrect.
Are we still talking about passing a zero-length license? If so, the
code shouldn't have reached CreateInstaceLic call at all, but should
have used plain vanilla CoCreateInstance. See the check at line 114.
I looked in the vb6controls.reg file and found the following registry
data:
// FlexGrid Control 6.0 license key
HKEY_CLASSES_ROOT\Licenses\ABCDEF567ABCD-11cf-91F6-C24434543F45 =
idfsdfrwesdfsdfgdfggdsdjfhdsjfssdjmf
This doesn't necessarily have anything to do with the license you should
pass to CreateInstaceLic. The way COM licensing works, you should obtain
IClassFactory2 interface of the object on a licensed machine, and call
IClassFactory2::RequestLicKey. You should store the returned string
somewhere - usually hard-coded in your program. On an unlicensed
machine, you pass this exact string to
IClassFactory2::CreateInstanceLic.

necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
