    Dim a As String
    Private Sub Form1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyDown
        a = a & e.KeyCode
        If (a = "6870" Or a = "7068") Then 'D 和  F同时按下
            MessageBox.Show(a)
        End If
    End Sub

    Private Sub Form1_KeyUp(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyUp
        a = Nothing
    End Sub

a = a & e.KeyCode这句有点不明白 &是加 还是啥？
