vb.net – 在用户关闭应用程序时禁用所有表单上的验证

我将此代码放在按钮单击处理程序中：

' Disable validation on the form.
'--------------------------------
Me.AutoValidate = System.Windows.Forms.AutoValidate.Disable

当我再次调用表单时,我将其用于名为objFormParents的表单对象：

' Reset validation on this form because the user may have closed it before.
'--------------------------------------------------------------------------
objFormParents.CausesValidation = True

我发现这在互联网上处理点击“X”图标：

' This will allow the user to close the form without the worry of controls doing validation from "X".
'----------------------------------------------------------------------------------------------------
Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message)

    Select Case ((m.WParam.ToInt64() And &HFFFF) And &HFFF0)

        Case &HF060 ' The user chose to close the form.
            Me.AutoValidate = System.Windows.Forms.AutoValidate.Disable
    End Select

    MyBase.WndProc(m)
End Sub
