Write a resource file

Context

Each converter DLL requires an associated information file. This file allows the converter architecture to read the properties of the converters in the DLL without having to load the DLL itself.

The following information is written to a resource file:

• A single CONARC_RESOURCE_FILE resource which contains an array of CONVERTER_DATA resources.

• Each CONVERTER_DATA resource describes the properties of a single converter. It specifies the UID of the converter, an array of MIME resources describing the data types from which the converter can convert and another array of MIME resources describing the data types to which the converter can convert.

• Each MIME resource specifies the supported MIME type. For example, text/html, and an array of LANG_DATA resources giving localized human-readable names for that MIME type.

• Each LANG_DATA resource specifies a language ID and a human-readable name for the MIME type in that language.

NOTE: The resource file is included within a start resource ... end block in the project file. Its target path must be\resource\convert\.

The following example is an information file for a converter DLL that contains one converter:

#include <conplugin.rh>
#include "ExampleConv.hrh"
RESOURCE CONARC_RESOURCE_FILE
    {
    converter_list =
        {
        CONVERTER_DATA
            {
            conv_uid = KExampleConvImplementationUid; // UID of the converter, as returned by CConverterBase2::Uid()
            from_list =
                {
                MIME
                    {
                    type = "example/qp";
                    lang_list =
                        {
                        // lang_id is a value from the TLanguage enumeration. 01 is English.
                        LANG_DATA{lang_id=01;translation="quoted-printable";
                        }
                    };
                }
            };
        to_list =
            {
            MIME
                {
                type = "example/text";
                lang_list =
                    {
                    LANG_DATA
                        {
                        lang_id = 01;
                        translation = "text";
                        };
                    }
                };
            }
        };
    }
