Let’s say that I want to get the size in bytes or in chars for the name field from:
struct record
{
int id;
TCHAR name [50];
};
sizeof(record.name) does not work.

The solution for this is not so pretty as you may think:
size_in_byte = sizeof(((struct record *) 0)->name)size_in_chars = _countof(((struct record *) 0)->name)If you want to use the second one on other platforms than Windows try:
#define _countof(array) (sizeof(array)/sizeof(array[0]))
