Enumerates language-specific resources, of the specified type and name, associated with a specified binary module. Extends EnumResourceLanguages by allowing more control over the enumeration.
Type: HMODULE
The handle to a module to search. Typically this is a language-neutral Portable Executable (LN file), and if flag RESOURCE_ENUM_MUI is set, then appropriate .mui files are included in the search. Alternately, this can be a handle to an .mui file or other LN file. If this is a specific .mui file, only that file is searched for resources.
If this parameter is NULL, it is equivalent to passing in a handle to the module used to create the current process.
Type: LPCTSTR
The type of the resource for which the language is being enumerated. Alternately, rather than a pointer, this parameter can be MAKEINTRESOURCE(ID), where ID is an integer value representing a predefined resource type. For a list of predefined resource types, see Resource Types. For more
information, see the Remarks section below.
Type: LPCTSTR
The name of the resource for which the language is being enumerated. Alternately, rather than a pointer, this parameter can be MAKEINTRESOURCE(ID), where ID is the integer identifier of the resource. For more information, see the Remarks section below.
Type: ENUMRESLANGPROC
A pointer to the callback function to be called for each enumerated resource language. For more information, see EnumResLangProcW.
Type: LONG_PTR
An application-defined value passed to the callback function. This parameter can be used in error checking.
Type: DWORD
The type of file to be searched. The following values are supported. Note that if dwFlags is zero, then the RESOURCE_ENUM_LN and RESOURCE_ENUM_MUI flags are assumed to be specified.
Type: LANGID
The localization language used to filter the search in the .mui file. This parameter is used only when the RESOURCE_ENUM_MUI flag is set in dwFlags. If zero is specified, then all .mui files are included in the search. If a nonzero LangId is specified, then the only .mui file searched will be the one matching the specified LangId.
Type: BOOL
Returns TRUE if the function succeeds or FALSE if the function does not find a resource of the type specified, or if the function fails for another reason. To get extended error information, call GetLastError.
If IS_INTRESOURCE(lpType) is TRUE, then lpType specifies the integer identifier of the given resource type. Otherwise, it is a pointer to a null-terminated string. If the first character of the string is a pound sign (#), then the remaining characters represent a decimal number that specifies the
integer identifier of the resource type. For example, the string "#258" represents the identifier 258.
Similarly, if IS_INTRESOURCE(lpName) is TRUE, then lpName specifies the integer identifier of the given resource. Otherwise, it is a pointer to a null-terminated string. If the first character of the string is a pound sign (#), then the remaining characters represent a decimal number that specifies the
integer identifier of the resource.
Starting with Windows Vista, the binary module is typically an LN file, and the enumeration will also include resources from the corresponding language-specific resource files (.mui files) that contain localizable language resources.
For each such resource found, EnumResourceLanguagesEx calls an application-defined callback function lpEnumFunc, passing to the callback function the language identifier (see Language Identifiers) of the language for which a resource was found (as well as the various other parameters that were passed to EnumResourceLanguagesEx).
The search can include both an LN file and its associated .mui files, or it can be limited either to a single binary module of any type, or to the .mui files associated with a single LN file. Also, by specifying an LN file for the hModule parameter and a nonzero LangId parameter, the search can be limited to the unique .mui file associated with that LN file and language.
The EnumResourceLanguagesEx function continues to enumerate resource languages until the callback function returns FALSE or all resource languages have been enumerated.
If hModule specifies an LN file, and both flags are selected, the languages enumerated include all languages whose resources reside either in the LN file or in any .mui files associated with it. If no .mui files are found, only languages from the LN file are returned.
If dwFlags contains RESOURCE_ENUM_MUI or NULL and LangId is 0, then the enumeration first includes the languages associated with all system-installed .mui files, using languages retrieved from EnumUILanguages.. Finally, if the RESOURCE_ENUM_LN flag is also set, the file designated by hModule is also searched.
If the LangId is nonzero, then only the .mui file corresponding to that language identifier will be searched. Language fallbacks will not be used. If an .mui file for that language does not exist, the enumeration will be empty (unless resources for that language exist in the LN file, and the flag is set to search the LN file as well).
The enumeration never includes duplicates: if resources for a particular language are contained in both the LN file and in an .mui file, the type will only be enumerated once.
For an example, see Creating a Resource List.
Note
The libloaderapi.h header defines EnumResourceLanguagesEx as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
