FbwfCacheDetail Class (Standard 8)

7/8/2014

Review the syntax, members, and examples of the FbwfCacheDetail WMI provider class for Windows Embedded 8 Standard (Standard 8).

This class stores information about files and directories that are modified.

The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties.

Syntax

class FbwfCacheDetail
{
  sint64 CacheSize;
  string FileName;
  uint32 OpenHandleCount;
  string VolumeName;
};

Members

This class defines the following types of members:

• Properties

Properties

This class defines the following properties.

Property	Data type	Qualifiers	Description
CacheSize	sint64	[Read]	Returns the size of the item in the write filter overlay.
FileName	string	[Read, Key]	Returns the absolute file path for the associated volume.
OpenHandleCount	uint32	[Read]	Returns the number of open handles on the item in the write filter overlay.
VolumeName	string	[Read, Key]	Returns the name of the volume.

Remarks

When querying for property values with a uint64 or sint64 data type in a scripting language such as VBScript, WMI returns string values. Unexpected results can occur when comparing these values, because comparing strings returns different results than comparing numbers. For example, "10000000000" is less than "9" when comparing strings, and 9 is less than 10000000000 when comparing numbers. To avoid confusion you should use the CDbl method in VBScript when properties of type uint64 or sint64 are retrieved from WMI.
