Enumerates resources of a specified type that are associated with a specified binary module. The search can include both an LN file and its associated .mui files, or it can be limited in several ways.
BOOL EnumResourceNamesExA( HMODULE hModule, LPCSTR lpType, ENUMRESNAMEPROCA lpEnumFunc, LONG_PTR lParam, DWORD dwFlags, LANGID LangId );
The handle to a module to search. Typically this is an 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 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 name. For more information, see EnumResNameProc.
An application-defined value passed to the callback function. This parameter can be used in error checking.
The type of file to search. 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 resources in .mui files associated with the LN 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 specified .mui file 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 the file specified by hModule, regardless of whether the file is an LN file, another type of 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 name that is enumerated.|
The localization 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.
The function 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.
If IS_INTRESOURCE(lpszType) is TRUE, then lpszType 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.
The enumeration search can include both an LN file and its associated .mui files. It can be limited to a single binary module of any type. It can also be limited to the .mui files associated with a single LN file. 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.
For each resource found, EnumResourceNamesEx calls an application-defined callback function lpEnumFunc, passing the name or the ID of each resource it finds, as well as the various other parameters that were passed to EnumResourceNamesEx.
If a resource has an ID, the ID is returned to the callback function; otherwise the resource name is returned to the callback function. For more information, see EnumResNameProc.
The EnumResourceNamesEx function continues to enumerate resource names until the callback function returns FALSE or all resource names for this type have been enumerated.
If hModule specifies an LN file, and both flags are selected, the names enumerated correspond to resources residing either in that LN file or the .mui files associated with it. If no .mui files are found, only names from the LN file are returned. After 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 names.
If dwFlags and LangId are both zero, then the function behaves like EnumResourceNames.
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 name will only be enumerated once.
