Is there some reason you are not using CHtmlView?

ATL::CComPtr<IOleWindow> oleWindow;
iOleObject_->QueryInterface(&oleWindow);

HWND hwndBrowser = NULL;
oleWindow->GetWindow(&hwndBrowser);

::MoveWindow(hwndBrowser, 0, 0, cx, cy, TRUE);

As an interesting addition, I noticed that IWebBrowser2::get_HWND gives NULL for the window, where I expected the same result as querying the IOleWindow interface.

Is there any API which sets the visibility state to WM_VISIBLE.
