示例1: Move

''' <summary>
''' Moves the provider to the specified position.
''' </summary>
''' <param name="x">The specified X screen coordinate.</param>
''' <param name="y">The specified Y screen coordinate</param>
Private Sub Move(ByVal x As Double, ByVal y As Double) Implements ITransformProvider.Move
    Dim leftInt As Integer = CInt(x)
    Dim topInt As Integer = CInt(y)

    If Not(CType(Me, ITransformProvider)).CanMove Then
        Throw New InvalidOperationException("Operation cannot be performed.")
    End If

    ' Move should never be allowed to place a control outside the 
    ' bounds of its container; the control should always be accessible 
    ' using the keyboard or mouse.
    ' Use the bounds of the parent window to limit the placement 
    ' of the custom control.
    Dim maxLeft As Integer = 10
    Dim maxTop As Integer = 10
    Dim maxRight As Integer = Me.customControl.formWidth - Me.customControl.Width - 10
    Dim maxBottom As Integer = Me.customControl.formHeight - Me.customControl.Height - 10

    If leftInt < maxLeft Then
        leftInt = 0
    End If
    If topInt < maxTop Then
        topInt = 0
    End If
    If leftInt > maxRight Then
        leftInt = maxRight
    End If
    If topInt > maxBottom Then
        topInt = maxBottom
    End If

    ' Invoke control method on separate thread to avoid clashing with UI.
    ' Use anonymous method for simplicity.
    Me.customControl.Invoke(New MethodInvoker(Sub()
        Me.customControl.Left = leftInt
        Me.customControl.Top = topInt
    End Sub))
