Public Function LOBYTE(ByVal wValue As Integer) As Byte
LOBYTE = Val("&H" & Right("00" & Hex(wValue), 2))
End FunctionLOBYTE extracts the low-order byte of a 16-bit integer (a word).
The macro returns the low-order byte of the value passed to it.
Although it may seem unusual to use string operations for what would otherwise be a mathematical computation, it is necessary to implement LOBYTE this way in VB. Other methods to perform this task can fail for large inputs because VB interprets them as negative values, which causes an equivalent mathematical computation to return an unwanted value.
