I’m trying to make some registry edits and I’m not sure I understand how specific dword values are calculated.

Here are two examples:

 [HKEY_CURRENT_USER\ControlPanel\Volume]
 "Volume"=dword:0xFFFFFFFF ; 0=off, 0xFFFFFFFF=maximum

 "Refresh"=dword:493E0 ; every 5 minutes

For the volume, how would I calculate what the range of options are if 0xFFFFFFFF is the max? And for “Refresh”, if 493E0 is every 5 minutes, how do I figure out what every minute, or every day or every hour would be?

This is a Motorola Symbol MK4000 WinCE 5.0 device.

    If you put the windows calculator into scientific mode, you can convert between HEX and regular DECIMAL easily.

    EDIT:
    The number 0x493E0 is 300000, which I imagine is the number of MILLISECONDS, divide that by 1000 to get the number of seconds (300), divide that by 60 to get the number of minutes (5).
