EVENT_CUSTOM
Defines an event-map entry for a custom event.
EVENT_CUSTOM(pszName, pfnFire, vtsParams )
Parameters
pszName
The name of the event.pfnFire
The name of the event firing function.vtsParams
A space-separated list of one or more constants specifying the function's parameter list.
Remarks
The vtsParams parameter 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_COLOR VTS_FONT
specifies a list containing a 32-bit integer representing an RGB color value, followed by a pointer to the IFontDisp interface of an OLE font object.
The VTS_ constants and their meanings are as follows:

Poznámka
Additional variant constants have been defined for all variant types, with the exception of VTS_FONT and VTS_PICTURE, that provide a pointer to the variant data constant. These constants are named using the VTS_Pconstantname convention. For example, VTS_PCOLOR is a pointer to a VTS_COLOR constant.
