ON_PROPNOTIFY

ON_PROPNOTIFY( theClass, id, dispid, pfnRequest, pfnChanged )

Parameters

theClass

The class to which this event sink map belongs.

id

The control ID of the OLE control.

dispid

The dispatch ID of the property involved in the notification.

pfnRequest

Pointer to a member function that handles the OnRequestEdit notification for this property. This function should have a BOOL return type and a BOOL* parameter. This function should set the parameter to TRUE to allow the property to change and FALSE to disallow. The function should return TRUE to indicate the notification was handled; otherwise FALSE.

pfnChanged

Pointer to a member function that handles the OnChanged notification for this property. The function should have a BOOL return type and a UINT parameter. The function should return TRUE to indicate that notification was handled; otherwise FALSE.

Remarks

Use the ON_PROPNOTIFY macro to define an event sink map entry for handling property notifications from an OLE control.

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.
