4.13 Message Table Resources

A message table is a resource that contains formatted text that is used to display an error message or message box. It has taken the place of the error table resource (which was never used). The data consists of a MESSAGE_RESOURCE_DATA structure, which contains one or more MESSAGE_RESOURCE_BLOCKS, which in turn may consist of one or more MESSAGE_RESOURCE_ENTRY structures. The structure is similar to that of the STRINGTABLE resource.

typedef struct _MESSAGE_RESOURCE_DATA {
  ULONG NumberOfBlocks;
  MESSAGE_RESOURCE_BLOCK Blocks[];
} MESSAGE_RESOURCE_DATA, *PMESSAGE_RESOURCE_DATA;

typedef struct _MESSAGE_RESOURCE_BLOCK {
  ULONG LowId;
  ULONG HighId;
  ULONG OffsetToEntries;
} MESSAGE_RESOURCE_BLOCK, *PMESSAGE_RESOURCE_BLOCK;

typedef struct _MESSAGE_RESOURCE_ENTRY {
  USHORT Length;
  USHORT Flags;
  UCHAR Text[];
} MESSAGE_RESOURCE_ENTRY, *PMESSAGE_RESOURCE_ENTRY;
