void FireEvent( DISPID dispid, BYTE FAR* pbParams, ... );
Parameters
dispid
The dispatch ID of the event to be fired.
pbParams
A descriptor for the event’s parameter types.
Remarks
Call this function, with any number of optional arguments, to fire a user-defined event from your control. Usually this function should not be called directly. Instead you will call the event-firing functions generated by ClassWizard 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 | IFontDisp* |
| VTS_HANDLE | HWND |
| VTS_PICTURE | IPictureDisp* |
| VTS_OPTEXCLUSIVE | OLE_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.
