使窗口只能保持永远最大化(屏蔽标题栏双击,绝对不闪)

 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
