The WebBrowser Control gives you control over what it downloads,
displays, and executes. To gain this control, you need to implement
your host's IDispatch so it handles DISPID_AMBIENT_DLCONTROL.
When the WebBrowser Control is instantiated, it will call your
IDispatch::Invoke with this ID. Set pvarResult to a combination
of following flags, using the bitwise OR operator, to indicate
your preferences.
STDMETHODIMP CAtlBrCon::Invoke(DISPID dispidMember, REFIID riid,
LCID lcid, WORD wFlags,
DISPPARAMS* pDispParams,
VARIANT* pvarResult,
EXCEPINFO* pExcepInfo,
UINT* puArgErr)
{
switch (dispidMember)
{
case DISPID_AMBIENT_DLCONTROL:
pvarResult->vt = VT_I4;
pvarResult->lVal = DLCTL_DLIMAGES | DLCTL_VIDEOS | DLCTL_NO_SCRIPTS;
break;
default:
return DISP_E_MEMBERNOTFOUND;
}
return S_OK;
}
