The ReadFromString Windows Management Instrumentation (WMI) class method, in Configuration Manager, reads SMS_ScheduleToken Server WMI Class objects from an interval string.

The following syntax is simplified from Managed Object Format (MOF) code and defines the method.

Syntax

SInt32 ReadFromString(  
   String StringData,  
     SMS_ScheduleToken TokenData[]  
);

Parameters

StringData
Data type: String

Qualifiers: [in]

The interval string (details in table below).

TokenData
Data type: SMS_ScheduleToken Array

Qualifiers: [out]

SMS_ScheduleToken Server WMI Class objects.


The ScheduleToken class uses two DWORDs to store the schedule data.   

Values for the first DWORD laid out as follows:
