PREfast Warning 240 (Windows CE 5.0)
240 - (<expression> && <non-zero constant>) always evaluates to Boolean result of <expression>.
Question: Was the bitwise-and operator intended?
This warning indicates that a constant value greater than one was detected on the right side of a logical-AND operation that occurs in a test context.
This expression reduces to a constant value of !!n, which is 0 or 1.
This warning is typically caused by an attempt to mask bits, in which case the operator should be &.
Example
