long in vba code example

Example 1: vba long integer value to bits

Function LongToBits$(ByVal n&)
    Dim i&
    LongToBits = "00000000000000000000000000000000"
    If n And &H80000000 Then
        Mid$(LongToBits, 1, 1) = "1"
        n = n And Not &H80000000
    End If
    For i = 32 To 2 Step -1
        If n And 1 Then Mid$(LongToBits, i, 1) = "1"
        n = n \ 2
    Next
End Function

'------------------------------------------------------------------------------

MsgBox LongToBits(0)			'<--displays: 00000000000000000000000000000000
MsgBox LongToBits(293781237)	'<--displays: 00010001100000101011111011110101
MsgBox LongToBits(-1)			'<--displays: 11111111111111111111111111111111

Example 2: excel vba high word from Long Integer

'If n is a 4-byte Long Integer, the Low (Left) Word is:
If n And &H8000& Then
  	LoWord = n Or &HFFFF0000
Else
    LoWord = n And &HFFFF&
End If

'If n is a 4-byte Long Integer, the High (Right) Word is:
HiWord = (n And &HFFFF0000) \ &H10000
