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 |
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 |
备注
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.
