Registering File Types and File Filters

Windows CE Services uses the registry entries to determine which conversions are available for a given file type and how to invoke the filter that supports the conversion. For this reason, you must register each file type and file filter properly by using the following procedure.

    To register file types and their filters

1. Register the file extension type.
2. Generate a class identifier (CLSID) for the file filter.
3. Register the file filter.

The following sections describe each step in detail and provide a sample file filter registry entry.

Note CEUTIL, a utility DLL, has functions that are especially helpful when you are dealing with the desktop registry entries for Windows CE Services. For information about CEUTIL, see "Using the CEUTIL Helper DLL for Windows CE Services."
