Computes the logical AND of two values. Both values are converted into Boolean, and if both are true then this expression returns true. If one or both values evaluate to false, this expression returns false. AndAlso is the "short circuit" version of the logical AND operator, returning false as soon as one of operands is evaluated to be false.
