[RESOLVED] Why Is This Bit Mask Not Working?

[ForumAccount]

Here is the code:

Option Strict On

Dim mask As ULong = &HFFFFFFFFUL
Dim result1 As ULong = 20L And mask '//disallows implicit conversions
Dim result2 As ULong = 20L And &HFFFFFFFFUL

If you put that into the IDE with Option Strict On, it will not let you compile because of 'result1'. I'm not sure I understand why. In the 'result2' assignment, I am explicitly saying to use an unsigned long, however it's not giving me any grief. Is the IDE doing that conversion to long without telling me?
