FILEMUIINFO structure

Contains information about a file, related to its use with MUI. Most of this data is stored in the resource configuration data for the particular file. When this structure is retrieved by GetFileMUIInfo, not all fields are necessarily filled in. The fields used depend on the flags that the application has passed to that function.

Note  Your MUI applications can use the MUI macros to access this structure.
 

Syntax


typedef struct _FILEMUIINFO {
  DWORD dwSize;
  DWORD dwVersion;
  DWORD dwFileType;
  BYTE  pChecksum[16];
  BYTE  pServiceChecksum[16];
  DWORD dwLanguageNameOffset;
  DWORD dwTypeIDMainSize;
  DWORD dwTypeIDMainOffset;
  DWORD dwTypeNameMainOffset;
  DWORD dwTypeIDMUISize;
  DWORD dwTypeIDMUIOffset;
  DWORD dwTypeNameMUIOffset;
  BYTE  abBuffer[8];
} FILEMUIINFO, *PFILEMUIINFO;

Members

dwSize

Size of the structure, including the buffer, which can be extended past the 8 bytes declared. The minimum value allowed is sizeof(FILEMUIINFO).

dwVersion

Version of the structure. The current version is 0x001.

dwFileType

The file type. Possible values are:

  • MUI_FILETYPE_NOT_LANGUAGE_NEUTRAL. The input file does not have resource configuration data. This file type is typical for older executable files. If this file type is specified, the other file types will not provide useful information.
  • MUI_FILETYPE_LANGUAGE_NEUTRAL_MAIN. The input file is an LN file.
  • MUI_FILETYPE_LANGUAGE_NEUTRAL_MUI. The input file is a language-specific resource file.
pChecksum

Pointer to a 128-bit checksum for the file, if it is either an LN file or a language-specific resource file.

pServiceChecksum

Pointer to a 128-bit checksum for the file, used for servicing.

dwLanguageNameOffset

Offset, in bytes, from the beginning of the structure to the language name string for a language-specific resource file, or to the ultimate fallback language name string for an LN file.

dwTypeIDMainSize

Size of the array for which the offset is indicated by dwTypeIDMainOffset. The size also corresponds to the number of strings in the multi-string array indicated by dwTypeNameMainOffset.

dwTypeIDMainOffset

Offset, in bytes, from the beginning of the structure to a DWORD array enumerating the resource types contained in the LN file.

dwTypeNameMainOffset

Offset, in bytes, from the beginning of the structure to a series of null-terminated strings in a multi-string array enumerating the resource names contained in the LN file.

dwTypeIDMUISize

Size of the array with the offset indicated by dwTypeIDMUIOffset. The size also corresponds to the number of strings in the series of strings indicated by dwTypeNameMUIOffset.

dwTypeIDMUIOffset

Offset, in bytes, from the beginning of the structure to a DWORD array enumerating the resource types contained in the LN file.

dwTypeNameMUIOffset

Offset, in bytes, from the beginning of the structure to a multi-string array enumerating the resource names contained in the LN file.

abBuffer

Remainder of the allocated memory for this structure. See the Remarks section for correct use of this array.

Remarks

All offsets are from the base of the structure. An offset of 0 indicates that the data is not available.

The following is an example showing how to access data for the position in the structure that is described by an offset. This example accesses the language name string with the position defined by dwLanguageNameOffset.


PFILEMUIINFO pFileMUIInfo = NULL;

Allocate_pFileMUIInfo_AndPassTo_GetFileMUIInfo(&pFileMUIInfo);

LPWSTR lpszLang = reinterpret_cast<LPWSTR>(reinterpret_cast<BYTE*>(pFileMUIInfo) + pFileMUIInfo->dwLanguageNameOffset);


This example uses two reinterpret casts. First the code casts to BYTE* so the pointer arithmetic for the offset will be done in bytes. Then the code casts the resulting pointer to the desired type.

Alternatively, the code can be written as shown below. The effect is the same; the choice is strictly one of style.


PFILEMUIINFO pFileMUIInfo = NULL;

Allocate_pFileMUIInfo_AndPassTo_GetFileMUIInfo(&pFileMUIInfo);

DWORD ix = pFileMUIInfo->dwLanguageNameOffset - offsetof(struct _FILEMUIINFO, abBuffer);
LPWSTR lpszLang = reinterpret_cast<LPWSTR>(&(pFileMUIInfo->abBuffer[ix]));
