Here they are in VB.NET:

Public Function TurnBitOn(value As Integer, bitToTurnOn As Integer) As Integer Return (value Or bitToTurnOn)
End Function

Public Function TurnBitOff(value As Integer, bitToTurnOff As Integer) As Integer Return (value And Not bitToTurnOff)
End Function

Public Function FlipBit(value As Integer, bitToFlip As Integer) As Integer Return (value Xor bitToFlip)
End Function

Public Function TurnBitPositionOn(value As Integer, bitPosition As Integer) As Integer Return (value Or (1 << bitPosition))
End Function

Public Function TurnBitPositionOff(value As Integer, bitPosition As Integer) As Integer Return (value And Not (1 << bitPosition))
End Function

Public Function FlipBitPosition(value As Integer, bitPosition As Integer) As Integer Return (value Xor (1 << bitPosition))
End Function
