Input Format Objects

Input Format objects provide programmatic access to the input formats supported by Log Parser.

Input Format objects are instantiated with the ProgId and the .NET COM wrapper class names specified in the following table:

Input Format	ProgId	.NET COM Wrapper Class Name
ADS	MSUtil.LogQuery.ADSInputFormat	COMADSInputContextClassClass
BIN	MSUtil.LogQuery.IISBINInputFormat	COMIISBINInputContextClassClass
CSV	MSUtil.LogQuery.CSVInputFormat	COMCSVInputContextClassClass
ETW	MSUtil.LogQuery.ETWInputFormat	COMETWInputContextClassClass
EVT	MSUtil.LogQuery.EventLogInputFormat	COMEventLogInputContextClassClass
FS	MSUtil.LogQuery.FileSystemInputFormat	COMFileSystemInputContextClassClass
HTTPERR	MSUtil.LogQuery.HttpErrorInputFormat	COMHttpErrorInputContextClassClass
IIS	MSUtil.LogQuery.IISIISInputFormat	COMIISIISInputContextClassClass
IISODBC	MSUtil.LogQuery.IISODBCInputFormat	COMIISODBCInputContextClassClass
IISW3C	MSUtil.LogQuery.IISW3CInputFormat	COMIISW3CInputContextClassClass
NCSA	MSUtil.LogQuery.IISNCSAInputFormat	COMIISNCSAInputContextClassClass
NETMON	MSUtil.LogQuery.NetMonInputFormat	COMNetMonInputContextClassClass
REG	MSUtil.LogQuery.RegistryInputFormat	COMRegistryInputContextClassClass
TEXTLINE	MSUtil.LogQuery.TextLineInputFormat	COMTextLineInputContextClassClass
TEXTWORD	MSUtil.LogQuery.TextWordInputFormat	COMTextWordInputContextClassClass
TSV	MSUtil.LogQuery.TSVInputFormat	COMTSVInputContextClassClass
URLSCAN	MSUtil.LogQuery.URLScanLogInputFormat	COMURLScanLogInputContextClassClass
W3C	MSUtil.LogQuery.W3CInputFormat	COMW3CInputContextClassClass
XML	MSUtil.LogQuery.XMLInputFormat	COMXMLInputContextClassClass

After instantiating an input format object, an application can set the input format parameters and use the object as an argument to the Execute or ExecuteBatch methods of the LogQuery object.

Methods

The Input Format objects do not expose methods.

Properties

The Input Format objects expose read/write properties with the same names and capitalization as the parameters accepted by the corresponding Log Parser input format.
For example, the MSUtil.LogQuery.EventLogInputFormat input format object exposes a "resolveSIDs" property that controls the resolveSIDs parameter of the EVT input format.
The value type accepted and returned by an input format object property depends on the nature of the values that can be specified for the input format parameter, as described by the following table:

Parameter values	Property value type	JScript Example
"ON"/"OFF" values	Boolean	oEVTInputFormat.resolveSIDs = true;
Enumeration values (e.g. "ASC"/"PRINT"/"HEX")	String	oEVTInputFormat.binaryFormat = "PRINT";
String values	String	oEVTInputFormat.stringsSep = ", ";
Numeric values	Number	oIISW3CInputFormat.recurse = 10;

For more information on Input Format Parameters, see the Input Formats Reference.

Examples

JScript example:

var oLogQuery = new ActiveXObject("MSUtil.LogQuery");

// Create EVT Input Format object
var oEVTInputFormat = new ActiveXObject("MSUtil.LogQuery.EventLogInputFormat");

// Set input format parameters
oEVTInputFormat.resolveSIDs = true;
oEVTInputFormat.binaryFormat = "PRINT";
oEVTInputFormat.stringsSep = ", ";
oEVTInputFormat.iCheckpoint = "MyCheckpoint.lpc";

// Create query text
var strQuery = "SELECT * FROM System";

// Execute query and receive a LogRecordSet
var oRecordSet = oLogQuery.Execute( strQuery, oEVTInputFormat );

VBScript example:

Dim oLogQuery
Dim oEVTInputFormat
Dim strQuery
Dim oRecordSet

Set oLogQuery = CreateObject("MSUtil.LogQuery")

' Create EVT Input Format object
Set oEVTInputFormat = CreateObject("MSUtil.LogQuery.EventLogInputFormat")

' Set input format parameters
oEVTInputFormat.resolveSIDs = True
oEVTInputFormat.binaryFormat = "PRINT"
oEVTInputFormat.stringsSep = ", "
oEVTInputFormat.iCheckpoint = "MyCheckpoint.lpc"

' Create query text
strQuery = "SELECT * FROM System"

' Execute query and receive a LogRecordSet
Set oRecordSet = oLogQuery.Execute ( strQuery, oEVTInputFormat )
