• GetAmbient Property Methods

• Data Members

• Typedefs

Methods

CComControlBase	The constructor.
~CComControlBase	The destructor.
ControlQueryInterface	Retrieves a pointer to the requested interface.
DoesVerbActivate	Checks that the iVerb parameter used by IOleObjectImpl::DoVerb either activates the control's user interface (iVerb equals OLEIVERB_UIACTIVATE), defines the action taken when the user double-clicks the control (iVerb equals OLEIVERB_PRIMARY), displays the control (iVerb equals OLEIVERB_SHOW), or activates the control (iVerb equals OLEIVERB_INPLACEACTIVATE).
DoesVerbUIActivate	Checks that the iVerb parameter used by IOleObjectImpl::DoVerb causes the control's user interface to activate and returns TRUE.
DoVerbProperties	Displays the control's property pages.
FireViewChange	Call this method to tell the container to redraw the control, or notify the registered advise sinks that the control's view has changed.
GetDirty	Returns the value of data member m_bRequiresSave.
GetZoomInfo	Retrieves the x and y values of the numerator and denominator of the zoom factor for a control activated for in-place editing.
InPlaceActivate	Causes the control to transition from the inactive state to whatever state the verb in iVerb indicates.
InternalGetSite	Call this method to query the control site for a pointer to the identified interface.
OnDraw	Override this method to draw your control.
OnDrawAdvanced	The default OnDrawAdvanced prepares a normalized device context for drawing, then calls your control class's OnDraw method.
OnKillFocus	Checks that the control is in-place active and has a valid control site, then informs the container that the control has lost focus.
OnMouseActivate	Checks that the UI is in user mode, then activates the control.
OnPaint	Prepares the container for painting, gets the control's client area, then calls the control class's OnDraw method.
OnSetFocus	Checks that the control is in-place active and has a valid control site, then informs the container the control has gained focus.
PreTranslateAccelerator	Override this method to provide your own keyboard accelerator handlers.
SendOnClose	Notifies all advisory sinks registered with the advise holder that the control has been closed.
SendOnDataChange	Notifies all advisory sinks registered with the advise holder that the control data has changed.
SendOnRename	Notifies all advisory sinks registered with the advise holder that the control has a new moniker.
SendOnSave	Notifies all advisory sinks registered with the advise holder that the control has been saved.
SendOnViewChange	Notifies all registered advisory sinks that the control's view has changed.
SetControlFocus	Sets or removes the keyboard focus to or from the control.
SetDirty	Sets the data member m_bRequiresSave to the value in bDirty.

GetAmbient Property Methods

GetAmbientAppearance	Retrieves DISPID_AMBIENT_APPEARANCE, the current appearance setting for the control: 0 for flat and 1 for 3D.
GetAmbientAutoClip	Retrieves DISPID_AMBIENT_AUTOCLIP, a flag indicating whether the container supports automatic clipping of the control display area.
GetAmbientBackColor	Retrieves DISPID_AMBIENT_BACKCOLOR, the ambient background color for all controls, defined by the container.
GetAmbientCharSet	Retrieves DISPID_AMBIENT_CHARSET, the ambient character set for all controls, defined by the container.
GetAmbientCodePage	Retrieves DISPID_AMBIENT_CODEPAGE, the ambient character set for all controls, defined by the container.
GetAmbientDisplayAsDefault	Retrieves DISPID_AMBIENT_DISPLAYASDEFAULT, a flag that is TRUE if the container has marked the control in this site to be a default button, and therefore a button control should draw itself with a thicker frame.
GetAmbientDisplayName	Retrieves DISPID_AMBIENT_DISPLAYNAME, the name the container has supplied to the control.
GetAmbientFont	Retrieves a pointer to the container's ambient IFont interface.
GetAmbientFontDisp	Retrieves a pointer to the container's ambient IFontDisp dispatch interface.
GetAmbientForeColor	Retrieves DISPID_AMBIENT_FORECOLOR, the ambient foreground color for all controls, defined by the container.
GetAmbientLocaleID	Retrieves DISPID_AMBIENT_LOCALEID, the identifier of the language used by the container.
GetAmbientMessageReflect	Retrieves DISPID_AMBIENT_MESSAGEREFLECT, a flag indicating whether the container wants to receive window messages (such as WM_DRAWITEM) as events.
GetAmbientPalette	Retrieves DISPID_AMBIENT_PALETTE, used to access the container's HPALETTE.
GetAmbientProperty	Retrieves the container property specified by id.
GetAmbientRightToLeft	Retrieves DISPID_AMBIENT_RIGHTTOLEFT, the direction in which content is displayed by the container.
GetAmbientScaleUnits	Retrieves DISPID_AMBIENT_SCALEUNITS, the container's ambient units (such as inches or centimeters) for labeling displays.
GetAmbientShowGrabHandles	Retrieves DISPID_AMBIENT_SHOWGRABHANDLES, a flag indicating whether the container allows the control to display grab handles for itself when active.
GetAmbientShowHatching	Retrieves DISPID_AMBIENT_SHOWHATCHING, a flag indicating whether the container allows the control to display itself with a hatched pattern when the UI is active.
GetAmbientSupportsMnemonics	Retrieves DISPID_AMBIENT_SUPPORTSMNEMONICS, a flag indicating whether the container supports keyboard mnemonics.
GetAmbientTextAlign	Retrieves DISPID_AMBIENT_TEXTALIGN, the text alignment preferred by the container: 0 for general alignment (numbers right, text left), 1 for left alignment, 2 for center alignment, and 3 for right alignment.
GetAmbientTopToBottom	Retrieves DISPID_AMBIENT_TOPTOBOTTOM, the direction in which content is displayed by the container.
GetAmbientUIDead	Retrieves DISPID_AMBIENT_UIDEAD, a flag indicating whether the container wants the control to respond to user-interface actions.
GetAmbientUserMode	Retrieves DISPID_AMBIENT_USERMODE, a flag indicating whether the container is in run-mode (TRUE) or design-mode (FALSE).

Data Members

m_bAutoSize	Flag indicating the control cannot be any other size.
m_bDrawFromNatural	Flag indicating that IDataObjectImpl::GetData and CComControlBase::GetZoomInfo should set the control size from m_sizeNatural rather than from m_sizeExtent.
m_bDrawGetDataInHimetric	Flag indicating that IDataObjectImpl::GetData should use HIMETRIC units and not pixels when drawing.
m_bInPlaceActive	Flag indicating the control is in-place active.
m_bInPlaceSiteEx	Flag indicating the container supports the IOleInPlaceSiteEx interface and OCX96 control features, such as windowless and flicker-free controls.
m_bNegotiatedWnd	Flag indicating whether or not the control has negotiated with the container about support for OCX96 control features (such as flicker-free and windowless controls), and whether the control is windowed or windowless.
m_bRecomposeOnResize	Flag indicating the control wants to recompose its presentation when the container changes the control's display size.
m_bRequiresSave	Flag indicating the control has changed since it was last saved.
m_bResizeNatural	Flag indicating the control wants to resize its natural extent (its unscaled physical size) when the container changes the control's display size.
m_bUIActive	Flag indicating the control's user interface, such as menus and toolbars, is active.
m_bUsingWindowRgn	Flag indicating the control is using the container-supplied window region.
m_bWasOnceWindowless	Flag indicating the control has been windowless, but may or may not be windowless now.
m_bWindowOnly	Flag indicating the control should be windowed, even if the container supports windowless controls.
m_bWndLess	Flag indicating the control is windowless.
m_hWndCD	Contains a reference to the window handle associated with the control.
m_nFreezeEvents	A count of the number of times the container has frozen events (refused to accept events) without an intervening thaw of events (acceptance of events).
m_rcPos	The position in pixels of the control, expressed in the coordinates of the container.
m_sizeExtent	The extent of the control in HIMETRIC units (each unit is 0.01 millimeters) for a particular display.
m_sizeNatural	The physical size of the control in HIMETRIC units (each unit is 0.01 millimeters).
m_spAdviseSink	A direct pointer to the advisory connection on the container (the container's IAdviseSink).
m_spAmbientDispatch	A CComDispatchDriver object that lets you retrieve and set the container's properties through an IDispatch pointer. For more information, see Implementing the IDispatch Interface.
m_spClientSite	A pointer to the control's client site within the container.
m_spDataAdviseHolder	Provides a standard means to hold advisory connections between data objects and advise sinks.
