Member Function Documentation

ForceVersion()

tResult ForceVersion

(

double

fForcedVersion

[in]

fForcedVersion

The version the printer use for output. Use the flags defined in IMediaDescription::tMediaDescriptionFlags.

Returns

Standard result code.

Return values

ERR_NOERROR	Everything went fine
ERR_INVALID_VERSION	Unknown version passed.

GetXML()

A_UTILS_NS::cString GetXML

(

)

const

Getter for the XML string of the collected DDL information.

Returns

the XML string containing the DDL description

ToFile()

tResult ToFile

(

const A_UTILS_NS::cString &

strFilename

Parameters

[in]

strFilename

- Path to file to use

Return values

ERR_FAILED

Saving process failed
