禁用关闭按钮而不隐藏控制框 [英] Disable the Close button without hiding the Controlbox

问题描述

我有一个应用程序，我不希望用户能够关闭表单.好吧，很简单.只需为表单设置 ControlBox = false 即可.

I have an application where I do not want the user to be able to close the form. Okay, easy enough. Just set ControlBox = false for the form.

但是，我想将应用程序图标保留在表单的左上角.次要我知道，但细节对我来说意义重大.

However, I would like to keep the application icon in the upper left corner of the form. Minor I know, but details mean something to me.

设置Controlbox = false 也会使应用程序的图标在表单的左上角消失.有没有办法解决这个问题??

Setting the Controlbox = false also makes the application's icon go away in the upper left corner of the form. Is there a way around this??

推荐答案

这里是我使用的代码.

我的 VB.Net 版本.

My VB.Net version of it.

Private Const CP_NOCLOSE_BUTTON As Integer = &H200
Protected Overrides ReadOnly Property CreateParams() As Windows.Forms.CreateParams
    Get
        Dim mdiCp As Windows.Forms.CreateParams = MyBase.CreateParams
        mdiCp.ClassStyle = mdiCp.ClassStyle Or CP_NOCLOSE_BUTTON
        Return mdiCp
    End Get
End Property
