Members

Size

Size of the structure, used to validate the structure version. This value is required.

pszCopyright

Pointer to copyright information about the service.

wMajorVersion

Major version number that is used to track changes to the service.

wMinorVersion

Minor version number that is used to track changes to the service.

wBuildVersion

Build version that is used to track changes to the service.

wStepVersion

Step version that is used to track changes to the service.

dwInputContentTypesCount

Number of content types that the service can receive.

prgInputContentTypes

Optional. Pointer to an array of input content types, following the format of the MIME content types, that identify the format that the service interprets when the application passes data. Examples of content types are "text/plain", "text/html" and "text/css".

Note  In Windows 7, the ELS services support only the content type "text/plain". A content types specification can be found at Text Media Types.

 

dwOutputContentTypesCount

Number of content types in which the service can format results.

prgOutputContentTypes

Optional. Pointer to an array of output content types, following the format of the MIME content types, that identify the format in which the service retrieves data.

dwInputLanguagesCount

Number of input languages supported by the service. This member is set to 0 if the service can accept data in any language.

prgInputLanguages

Pointer to an array of the input languages, following the IETF naming convention, that the service accepts. This member is set to NULL if the service can work with any input language.

dwOutputLanguagesCount

Number of output languages supported by the service. This member is set to 0 if the service can retrieve data in any language, or if the service ignores the output language.

prgOutputLanguages

Pointer to an array of output languages, following the IETF naming convention, in which the service can retrieve results. This member is set to NULL if the service can retrieve results in any language, or if the service ignores the output language.

dwInputScriptsCount

Number of input scripts supported by the service. This member is set to 0 if the service can accept data in any script.

prgInputScripts

Pointer to an array of input scripts, with Unicode standard script names, that are supported by the service. This member is set to NULL if the service can work with any scripts, or if the service ignores the input scripts.

dwOutputScriptsCount

Number of output scripts supported by the service. This member is set to 0 if the service can retrieve data in any script, or if the service ignores the output scripts.

prgOutputScripts

Pointer to an array of output scripts supported by the service. This member is set to NULL if the service can work with any scripts, or the service ignores the output scripts.

guid

Globally unique identifier (GUID) for the service.

pszCategory

Pointer to the service category for the service, for example, "Language Detection".

pszDescription

Pointer to the service description. This text can be localized.

dwPrivateDataSize

Size, in bytes, of the private data for the service. This member is set to 0 if there is no private data.

pPrivateData

Pointer to private data that the service can expose. This information is static and updated during installation of the service.

pContext

Reserved for internal use.

IsOneToOneLanguageMapping

Flag indicating the language mapping between input language and output language that is supported by the service. Possible values are shown in the following table.

Value	Meaning
0	The input and output languages are not paired and the service can receive data in any of the input languages and render data in any of the output languages.
1	The arrays of the input and output languages for the service are paired. In other words, given a particular input language, the service retrieves results in the paired language defined in the output language array. Use of the language pairing can be useful, for example, in bilingual dictionary scenarios.

 

HasSubservices

Flag indicating if the service has subservices, that is, other services that plug into the service. This flag is used in service enumeration to determine if the parent service must be called to get a list of subservices. Possible values are shown in the following table.

Value	Meaning
0	The service is a regular service that stands alone and has no subservices.
1	The service acts as a parent for subservices.

 

OnlineOnly

Reserved for future use.

ServiceType

Reserved for future use.

Remarks

Structures of this type are created in an application call to MappingGetServices.
