[RESOLVED] [2008] The "or" keyword

[masfenix]

Hey guys,
I used the vb.net to c# converter to convert john's formanimator code to csharp.

However, he has this method in his code:

'Windows API function used to animate the form.
    Private Declare Auto Function AnimateWindow Lib "user32" (ByVal hWnd As IntPtr, _
                                                              ByVal dwTime As Integer, _
                                                              ByVal dwFlags As Integer) As Boolean
 
   'Animates the form automatically when it is loaded.
    Private Sub m_Form_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles m_Form.Load
        'MDI child forms do not support transparency so do not try to use the Blend method.
        If Me.m_Form.MdiParent Is Nothing OrElse Me.m_Method <> AnimationMethod.Blend Then
            'Activate the form.
            Me.AnimateWindow(Me.m_Form.Handle, _
                             Me.m_Duration, _
                             Me.AW_ACTIVATE Or Me.m_Method Or Me.m_Direction)
        End If
    End Sub

and the associated variables + their types:

Public Enum AnimationDirection
        Right = &H1
       Left = &H2
        Down = &H4
        Up = &H8
    End Enum
 
   Public Enum AnimationMethod
          Roll = &H0    
        Centre = &H10 
        Slide = &H40000
        Blend = &H80000
    End Enum
 
 Private Const AW_HIDE As Integer = &H10000      'Hide the form.
    Private Const AW_ACTIVATE As Integer = &H20000  'Activate the form.
 
    Private m_Method As AnimationMethod         'The animation method used to show and hide the form.
    Private m_Direction As AnimationDirection   'The direction in which to Roll or Slide the form.

So
now I dont understand how his hexadecimal values are working. The API is expecting an integer for "flags" for its last parameter.
however John is using

Me.AW_ACTIVATE Or Me.m_Method Or Me.m_Direction

which dosnt make sense to me.. what does OR do in this case? adds them up? because i think that the "flags" parameter (which is an int) must contain information about activate/hide, methodoftravel, and direction of travel.

So what does this mean and how can I incorparate it into csharp.

thanks
