| Code: | ' Return True if a particular bit in nBits is set.
' Bit 0 is the least significant bit.
Function IsBitSet( ByVal nBits As Long, ByVal nBitNum As Integer ) As Boolean
IsBitSet = GetBitNum( nBits, nBitNum ) > 0
End Function
' Return a particular bit from nBits.
' Bit 0 is the least significant bit.
Function GetBitNum( ByVal nBits As Long, ByVal nBitNum As Integer ) As Long
Do While nBitNum > 0
nBitNum = nBitNum - 1
nBits = Int( nBits / 2 ) ' shift right
Loop
GetBitNum = nBits Mod 2
End Function
' Set a particular bit in nBits.
' It does not matter what the previous status of the bit was,
' end ends up as a 1 bit.
' Bit 0 is the least significant bit.
Function SetBit( ByVal nBits As Long, ByVal nBitNum As Integer ) As Long
nBit = 1
Do While nBitNum > 0
nBitNum = nBitNum - 1
nBit = nBit * 2 ' shift left
Loop
SetBit = nBits Or nBit
End Function
' Clear a particular bit in nBits.
' It does not matter what the previous status of the bit was,
' end ends up as a 0 bit.
' Bit 0 is the least significant bit.
Function ClearBit( ByVal nBits As Long, ByVal nBitNum As Integer ) As Long
Dim nBit As Long
nBit = 1
Do While nBitNum > 0
nBitNum = nBitNum - 1
nBit = nBit * 2 ' shift left
Loop
ClearBit = nBits And (Not nBit)
End Function

What should I do about an ex-boyfriend who keeps blaming me? My ex-boyfriend keeps blaming me for the problems he's having now. He says that he's lost friends due to the fact that we were dating, but I didn't do anything to his friends, or even once suggest that I didn't like those friends. He also says that my life is perfect and happy and his is horrible, but I was the one there talking with him for hours at night trying to comfort him, while I couldn't get out more than 4 sentences about the problems I was having.
