Enumerates resource types associated with a specified binary module. The search can include both a language-neutral Portable Executable file (LN file) and its associated .mui files. Alternately, it can be limited to a single binary module of any type, or to the .mui files associated with a single LN file. The search can also be limited to a single associated .mui file that contains resources for a specific language.
For each resource type found, EnumResourceTypesEx calls an application-defined callback function lpEnumFunc, passing the resource type it finds, as well as the various other parameters that were passed to EnumResourceTypesEx.
BOOL EnumResourceTypesExA( HMODULE hModule, ENUMRESTYPEPROCA lpEnumFunc, LONG_PTR lParam, DWORD dwFlags, LANGID LangId );
The handle to a module to be searched. Typically this is an LN file, and if flag RESOURCE_ENUM_MUI is set, then appropriate .mui files can be included in the search. Alternately, this can be a handle to an .mui file or other LN file.
If this parameter is NULL, it is equivalent to passing in a handle to the module used to create the current process.
A pointer to the callback function to be called for each enumerated resource type. For more information, see EnumResTypeProc.
An application-defined value passed to the callback function.
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.
||Search for resource types in one of the .mui files associated with the file specified by hModule and with the current language preferences, following the usual Resource Loader strategy (see User Interface Language Management). Alternately, if LangId is nonzero, then only the .mui file of the language as specified by LangId will be searched. Typically this flag should be used only if hModule references an LN file. If hModule references an .mui file, then that file is actually covered by the RESOURCE_ENUM_LN flag, despite the name of the flag.|
||Searches only the file specified by hModule, regardless of whether the file is an LN file or an .mui file.|
||Performs extra validation on the resource section and its reference in the PE header while doing the enumeration to ensure that resources are properly formatted. The validation sets a maximum limit of 260 characters for each type that is enumerated.|
The language used to filter the search in the MUI module. This parameter is used only when the RESOURCE_ENUM_MUI flag is set in dwFlags. If zero is specified, then all .mui files that match current language preferences are included in the search, following the usual Resource Loader strategy (see User Interface Language Management). If a nonzero LangId is specified, then the only .mui file searched will be the one matching the specified LangId.
Returns TRUE if successful 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.
The EnumResourceTypesEx function continues to enumerate resource types until the callback function returns FALSE or all resource types have been enumerated.
If hModule specifies an LN file, and both flags are selected, the types enumerated correspond to resources residing either in the LN file or in the .mui files associated with it. If no .mui files are found, only types from the LN file are returned. Once one appropriate .mui file is found the search will not continue further, because all .mui files corresponding to a single LN file have the same resource types.
If dwFlags and LangId are both zero, then the function behaves like EnumResourceTypes.
If 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.
