1. Problem creating an ActiveX inside another ActiveX (in a separate thread)

I'm trying to create an ActiveX (let say A) which creates a second UI Thread
containing another ActiveX (let say B) - with MFC and Visual C++. The
problem I have is the following message when creating the ActiveX B in the
thread window of the ActiveX B:

** Message **
CoCreateInstance of OLE control {1E9AEBC8-891B-11D6-8661-00D05915F009}
failed.
***

When I try to run the code from a standard MFC application, no problem: the
thread can open its window and create the ActiveX B inside this window...

The code I'm using to create the ActiveX B inside the thread window (of the
ActiveX A) is the following:

ThreadWindow::ThreadWindow() // Of ActiveX A
{
 Create(NULL, _T("UI Thread Window "));

 CActiveXB *b = new CActiveXB;
 b->Create(NULL, WS_VISIBLE | WS_CHILD, CRect(0,0,100,100), this,
ID_ACTIVEX_B);

Also:

- I'm calling AfxEnableControlContainer() in the App:InitInstance of the
ActiveX A.
- I'm launching the UI thread with AfxBeginThread in the ActiveX's
initaliazion code

Do any one know what is wrong?

Thank you very much in advance for any help!
