COleControl::FireEvent

Fires a user-defined event from your control with any number of optional arguments,.

void AFX_CDECL FireEvent( 
   DISPID dispid, 
   BYTE* pbParams, 
   ...  
);

Parameters

  • dispid
    The dispatch ID of the event to be fired.

  • pbParams
    A descriptor for the event's parameter types.

Remarks

Usually this function should not be called directly. Instead you will call the event-firing functions in the event map section of your control's class declaration.

The pbParams argument is a space-separated list of VTS_. One or more of these values, separated by spaces (not commas), specifies the function's parameter list. Possible values are as follows:

Symbol

Parameter type

VTS_COLOR

OLE_COLOR

VTS_FONT

VTS_HANDLE

VTS_PICTURE

IPictureDisp*

VTS_OPTEXCLUSIVE

VTS_TRISTATE

OLE_TRISTATE

VTS_XPOS_HIMETRIC

OLE_XPOS_HIMETRIC

VTS_YPOS_HIMETRIC

OLE_YPOS_HIMETRIC

VTS_XPOS_PIXELS

OLE_XPOS_PIXELS

VTS_YPOS_PIXELS

OLE_YPOS_PIXELS

VTS_XSIZE_PIXELS

OLE_XSIZE_PIXELS

VTS_YSIZE_PIXELS

OLE_XSIZE_PIXELS

VTS_XSIZE_HIMETRIC

OLE_XSIZE_HIMETRIC

VTS_YSIZE_HIMETRIC

OLE_XSIZE_HIMETRIC

Note

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.
