ON_EVENT_REFLECT
The ON_EVENT_REFLECT macro, when used in the event sink map of an OLE control's wrapper class, receives events fired by the control before they are handled by the control's container.
ON_EVENT_REFLECT(theClass, dispid, pfnHandler, vtsParams )
Parameters
theClass
The class to which this event sink map belongs.dispid
The dispatch ID of the event fired by the control.pfnHandler
Pointer to a member function that handles the event. This function should have a BOOL return type and parameter types that match the event's parameters (see vtsParams). The function should return TRUE to indicate the event was handled; otherwise FALSE.vtsParams
A sequence of VTS_ constants that specifies the types of the parameters for the event. These are the same constants that are used in dispatch map entries such as DISP_FUNCTION.
Remarks
The vtsParams argument is a space-separated list of values from the VTS_ constants.
One or more of these values separated by spaces (not commas) specifies the function's parameter list. For example:
VTS_I2 VTS_BOOL
specifies a list containing a short integer followed by a BOOL.
For a list of the VTS_ constants, see EVENT_CUSTOM.
