Namespace:  System.Web.Security
Assembly:  System.Web (in System.Web.dll)

'Declaration
Public Shared ReadOnly Property UserIsOnlineTimeWindow As Integer

Property Value

Type: System.Int32
The number of minutes after the last-activity date/time stamp for a user during which the user is considered online.

The UserIsOnlineTimeWindow property value is checked during the call to GetNumberOfUsersOnline. If the LastActivityDate for a user is greater than the current date and time minus the UserIsOnlineTimeWindow value in minutes, then the user is considered online. You can determine whether a membership user is considered online with the IsOnline property of the MembershipUser class.

The LastActivityDate for a user is updated when a user's credentials are successfully validated by the ValidateUser method. You can also update the LastActivityDate for a membership user when you call one of the GetUser overloads. If you call a GetUser overload that takes a userIsOnline parameter, specify a value of true to update the LastActivityDate for the user.

The following code example shows the membership element in the system.web section of the Web.config file for an ASP.NET application. It specifies that the application use an instance of the SqlMembershipProvider and sets the userIsOnlineTimeWindow attribute to 20 minutes.

<membership defaultProvider="SqlProvider"
  userIsOnlineTimeWindow="20">
  <providers>
    <add name="SqlProvider"
      type="System.Web.Security.SqlMembershipProvider"
      connectionStringName="SqlServices"
      enablePasswordRetrieval="true"
      enablePasswordReset="false"
      requiresQuestionAndAnswer="true"
      passwordFormat="Encrypted"
      applicationName="MyApplication" />
  </providers>
</membership>
