I wrote an ActiveX control that has a few methods (SendMessage(VARIANT), BSTR
GetMessage(), SetTimerSpeed(long)).

I get an error when the following line is executed in genaxmodule.py: 
axw = wx.activex.ActiveXWindow(f, clsid)

The error was: Debug Assertion Failed.
It allowed me to bring up the VC++ debugger, and found that the error was in
winocc.cpp line 279.  That particular line is:
CString str;

Strange that it should err out there.  But the whole function that surrounds
that line is:
int CWnd::GetWindowTextLength() const
{
	ASSERT(::IsWindow(m_hWnd) || (m_pCtrlSite != NULL));

	if (m_pCtrlSite == NULL)
		return ::GetWindowTextLength(m_hWnd);
	else
	{
		CString str;

		m_pCtrlSite-> GetWindowText(str);
		return (int)str.GetLength();
	}
}

Looking at the call stack, m_hWnd and m_pCtrlSite both have values of
0x00000000.  So the ASSERT should fail.  

How to fix this problem??
