添加变量:
Public Const SC_MAXMIZE As Int32 = 61730 '最大化时双击标题栏消息的值,还可设置其他值,完成相应功能
添加方法:
    Protected Overrides Sub WndProc(ByRef m As Message)
        If m.WParam.ToInt32 = SC_MAXMIZE Then
            Me.WindowState = FormWindowState.Maximized
        Else
            MyBase.WndProc(m)
        End If
    End Sub

或者是:
   Protected Overrides Sub WndProc(ByRef m As Message)
        If m.WParam.ToInt32 <> SC_MAXMIZE Then
            MyBase.WndProc(m)
        End If
    End Sub
绝对不闪~~呵呵
