Examples

The following example shows how to use the EventKeywords class to redefine event keywords. This code example is part of a larger example provided for the EventSource class.

public static class Keywords
{
    public const EventKeywords Page = (EventKeywords)1;
    public const EventKeywords DataBase = (EventKeywords)2;
    public const EventKeywords Diagnostic = (EventKeywords)4;
    public const EventKeywords Perf = (EventKeywords)8;
}

Public Class Keywords
    Public Const Page As EventKeywords = CType(1, EventKeywords)
    Public Const DataBase As EventKeywords = CType(2, EventKeywords)
    Public Const Diagnostic As EventKeywords = CType(4, EventKeywords)
    Public Const Perf As EventKeywords = CType(8, EventKeywords)
End Class

Remarks

You can customize the meaning of a keyword by assigning different names to the flags.
