Creating a Resource List
The following example creates a list of every resource in the HAND.EXE file.
The list is written to the RESINFO.TXT file.
The code demonstrates how to load the executable file, create a file in which
to write resource information, and call the
EnumResourceTypes function to send each resource type found in the module to the
application-defined callback function
EnumTypesFunc. See
EnumResTypeProc for information on callback functions of this type. This callback function
uses the
EnumResourceNames function to pass the name of every resource within the specified type to
another application-defined callback function,
EnumNamesFunc. See
EnumResNameProc for information on callback functions of this type.
EnumNamesFunc uses the
EnumResourceLanguages function to pass the language of every resource of the specified type and
name to a third callback function,
EnumLangsFunc. See
EnumResLangProc for information on callback functions of this type.
EnumLangsFunc writes information about the resource of the specified type, name, and
language to the RESINFO.TXT file.

DWORD cbWritten; // number of bytes written to res. info. file
