Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Gets or sets the interval to be used for grouping events of the same type.
public:
property TimeSpan GroupWithinInterval { TimeSpan get(); void set(TimeSpan value); };
public TimeSpan GroupWithinInterval { get; set; }
member this.GroupWithinInterval : TimeSpan with get, set
Public Property GroupWithinInterval As TimeSpan
Returns a TimeSpan value containing the interval used for grouping events of the same type.
The following example initializes a new WqlEventQuery and displays the event query string.
using System;
using System.Management;
public class EventSample
{
public static void Main(string[] args)
{
WqlEventQuery query = new WqlEventQuery();
query.EventClassName = "__InstanceCreationEvent";
query.Condition = "TargetInstance ISA 'Win32_NTLogEvent'";
query.GroupWithinInterval = new TimeSpan(0, 0, 10);
System.Collections.Specialized.StringCollection collection =
new System.Collections.Specialized.StringCollection();
collection.Add("TargetInstance.SourceName");
query.GroupByPropertyList = collection;
query.HavingCondition = "NumberOfEvents > 25";
Console.WriteLine(query.QueryString);
return;
}
}
Imports System.Management
Public Class EventSample
Public Overloads Shared Function _
Main(ByVal args() As String) As Integer
Dim query As New WqlEventQuery
query.EventClassName = "__InstanceCreationEvent"
query.Condition = "TargetInstance ISA 'Win32_NTLogEvent'"
query.GroupWithinInterval = New TimeSpan(0, 0, 10)
Dim collection As New System.Collections.Specialized. _
StringCollection
collection.Add("TargetInstance.SourceName")
query.GroupByPropertyList = collection
query.HavingCondition = "NumberOfEvents > 25"
MessageBox.Show(query.QueryString)
End Function 'Main
End Class
Setting this property value overrides any previous value stored in the object. The query string is rebuilt to reflect the new interval.
Null, if there is no grouping involved; otherwise, the interval in which WMI should group events of the same type.
Full trust for the immediate caller. This member cannot be used by partially trusted code. For more information, see Using Libraries from Partially Trusted Code.
