Converting long to two integers

Converting long to two integers

Question:
How do you convert a long integer to two integer values (that is, get the low word and high word contained in a long integer)?Danial Appleman’s API Guide discusses a function to do this, but it requires distribution of another DLL. How can I retrieve these values without using Dan Appleman’s function/DLL?

Answer:
The following two functions seem to end up in nearly every app I write! Enjoy…

Public Function WordHi(LongIn As Long) As Integer   '   ' Mask off low word then do integer divide to   ' shift right by 16.   '   WordHi = (LongIn And &HFFFF0000)  &H10000End FunctionPublic Function WordLo(LongIn As Long) As Integer   '   ' Low word retrieved by masking off high word.   ' If low word is too large, twiddle sign bit.   '   If (LongIn And &HFFFF&) > &H7FFF Then      WordLo = (LongIn And &HFFFF&) - &H10000   Else      WordLo = LongIn And &HFFFF&   End IfEnd Function
