how to remove once added object from a global namespace?

[the-Arioch]

Hello, maybe it is stupid to ask here, but you did not publish your mail.

also, the original host-centered ActiveScripting SDK or ScriuptControls SDK did not survive on the internet. It was all paper-only back in 2000s...

So, there is a iScriptControl.AddObject interface, but it does NOT return any token to control the bridge after it was created

I know using your code instead of the SDK (code by contract) is stupid (code for implementation), actually twice stupid (code for someone else's implementation), but that was the best i could find

I was thinking about calling AddObject(<name to remove>, NULL but your code would throw AV there, clearly that was not an expected way...

CTScriptObject::CTScriptObject(IDispatch *pObject, VARIANT_BOOL bAddMembers)
{
	m_cRef = 1;
	m_pObject = pObject;
	m_pObject->AddRef();
	m_bAddMembers = bAddMembers;
}

I may create and register a dummy no-properties iDispatch stub, but that feels even more stupid than registering NULL

Also, that would not de-pollute the global namespace.
Also, i don;t know and feel insecure if that will clear away the secondary objects that very (bAddMembers)

Now why should global objects ever be de-registered? Huh... our legacy app was designed in a clever way to use global objects in stead of functio narguments to handle events...

Dunno, i feel like going to hunt for leaked Win2000 sources now, i really don't know where to look for information now... Well, sorry for whining.

I just hope you had hoarded a lto of AS/WSC/WSH documents and can give some authoritative clue...

anyway, there seems the error overlooked in your code

Win10 x86 code, when calling AddObject("somename", NULL, FALSE) throws EOleException with message 'The object cannot be nothing'

this makes me sad about de-registering

OTOH this means your code should add an explicit NULL check :-)

And no way to override it, the second call results in somewhat expected

EOleException with message 'An object with the given name has already been added

Hello,

In version 1.2.5.5, as a temporary measure, calling AddObject with NULL now removes the previously added object from the global namespace.

Thanks, but i believe you should rather mimic stock win32 behavior - fail explicitly. That is why i reported the tests above.

Once the object is inserted it can not be replaced with neither NULL not another object (until ::Reset called), which the exact error texts pasted above. Hmmm, i probably should had quieried and pasted HRESULT instead... well, guess you can make a test easily.

The point it, you did not account for that case at all, while Microsoft did and coded in a very specific behavior/checks for two scenarios:

• there was no object yet, the function is called for the first time, but with the NULL object
• there was some object already, the function is called (for a given name) again, regardless real object or NULL

Was my NULL test above the first or the second call i actually do not remember and do not think it makes a practical difference. The point is, the code you strive to mimic does both checks and explicitly fails in both cases, while your code seemed to have no defense programming upon flawed API use
