NMCOLUMNVARIANT structure

The NMCOLUMNVARIANT structure provides a line in the top pane of the Event Viewer that serves as a container for all possible data inserted into a column.

Syntax

typedef struct {
  NMCOLUMNTYPE Type;
  union {
    BYTE        Uint8Val;
    char        Sint8Val;
    WORD        Uint16Val;
    short       Sint16Val;
    DWORD       Uint32Val;
    LONG        Sint32Val;
    DOUBLE      Float64Val;
    DWORD       FrameVal;
    BOOL        YesNoVal;
    BOOL        OnOffVal;
    BOOL        TrueFalseVal;
    BYTE        MACAddrVal[MAC_ADDRESS_SIZE];
    IPX_ADDRESS IPXAddrVal;
    DWORD       IPAddrVal;
    DOUBLE      VarTimeVal;
    LPSTR       pStringVal;
