Windows .NET 应用程序在断电后无法打开。在事件查看器中显示未从 My.Settings 获取价值
Windows .NET Application not opening After Power failure. In Event viewer showing Not getting Value from My.Settings
我正在开发一个基于 VB.NET 的 SCADA 系统。我的应用程序在我所有的机器上运行良好。当我们启动系统应用程序后突然断电或关机时打不开。在事件查看器中显示跟随错误。那里 R_LOT_SIZE 是 MY.Setting 变量。如果 My.setting 属性 有任何值并且我们关闭系统时出现此错误。
