New Post: An example to share vb6 script control vs clearscript

The code above initially calls AddHostObject() to create the "TEST1" global property. What you may not realize - most likely because of insufficient documentation on our part - is that AddHostobject() creates a read-only global property. Subsequent reassignment is quietly ignored. This is by design - to prevent script code from clobbering the host's API, and to achieve compatibility with ClearScript's original JScript/VBScript behavior.

On the other hand, properties created via Script can be reassigned normally. Instead of:

V8JS.AddHostObject("TEST1", T1);

please try:

V8JS.Script.TEST1 = T1;

Cheers!
