COMPAT enumeration
The following flags determine the behavior of registered Microsoft ActiveX controls.
Syntax

Constants
- COMPAT_AGGREGATE
-
This control is aggregated.
- COMPAT_NO_OBJECTSAFETY
-
This control is not safe for scripting, even if it implements IObjectSafety.
- COMPAT_NO_PROPNOTIFYSINK
-
A property notify sink is not attached to this control.
- COMPAT_SEND_SHOW
-
For this control, IOleObject::DoVerb is called with OLEIVERB_SHOW before IOleObject::DoVerb is called with OLEIVERB_INPLACEACTIVATE.
- COMPAT_SEND_HIDE
-
For this control, IOleObject::DoVerb is called with OLEIVERB_HIDE before IOleInPlaceObject::InPlaceDeactivate is called.
- COMPAT_ALWAYS_INPLACEACTIVATE
-
For this control, IOleObject::DoVerb is called with OLEIVERB_INPLACEACTIVATE.
- COMPAT_NO_SETEXTENT
-
The amount of space required by this control's container is not specified.
- COMPAT_NO_UIACTIVATE
-
This control cannot activate the UI elements of the current document host.
- COMPAT_NO_QUICKACTIVATE
-
This control does not implement IQuickActivate or should not be activated quickly.
- COMPAT_NO_BINDF_OFFLINEOPERATION
-
A cached version of this control is never used.
- COMPAT_EVIL_DONT_LOAD
-
This control is never used.
- COMPAT_PROGSINK_UNTIL_ACTIVATED
-
This control cannot be used for scripting until in-place activation is complete.
- COMPAT_USE_PROPBAG_AND_STREAM
-
Both IPersistPropertyBag::Load and IPersistStreamInit::Load are called when using this control.
- COMPAT_DISABLEWINDOWLESS
-
This control cannot be in-place activated without a window.
- COMPAT_SETWINDOWRGN
-
This control cannot have UI outside of the window.
- COMPAT_PRINTPLUGINSITE
-
This control has printing capabilities that should be used instead of those provided by Internet Explorer.
- COMPAT_INPLACEACTIVATEEVENWHENINVISIBLE
-
This control is in-place activated whether or not it is visible.
- COMPAT_NEVERFOCUSSABLE
-
This control can never receive focus.
- COMPAT_ALWAYSDEFERSETWINDOWRGN
-
This control is allowed to have, at most, one pending resize request.
- COMPAT_INPLACEACTIVATESYNCHRONOUSLY
-
This control is in-place activated syncronously.
- COMPAT_NEEDSZEROBASEDDRAWRECT
-
This control is positioned in the upper-left corner of the host window.
- COMPAT_HWNDPRIVATE
-
This control does not provide access to its window handle.
- COMPAT_SECURITYCHECKONREDIRECT
-
This control is prevented from accessing content from another domain when redirected by the original server.
- COMPAT_SAFEFOR_LOADING
-
Internet Explorer 7 and later. In the Internet zone, Internet Explorer checks every control for IObjectSafety to determine safety status quickly and abort instantiation as soon as possible. If a particular control doesn't implement IObjectSafety or component categories yet still needs to be instantiated in Internet Explorer without data or scripting, this compatibility flag can be used to disable the frontloaded safety check and revert back to Internet Explorer 6 behavior. See Safe Initialization and Scripting for ActiveX Controls.
Remarks
These enumeration members are bit masks that determine how ActiveX controls are used in Internet Explorer. Values are stored in the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility.
