A. There are some operations in Windows NT where you need to give a value as hexadecimal rather than binary or decimal, for example setting which drives should be excluded from a users view (see 'Q. How can I hide drive x from users?')
The easiest way to convert is to use the Calculator application in Scientific mode:
- Start Calculator (calc.exe)
- From the view menu select 'Scientific'
- Select 'Bin' and set the data type to 'Dword' (Dword is 4 bytes (32 bits), the biggest possible in calc)
- Enter you binary string
- Select 'Hex' and your binary number is converted to Hex
Hexadecimal is base 16 and each digit can therefore be between 0 and 15 (0-9, A-F). Binary is base 2 and each digit can therefore be 0 or 1.
