如何调试未处理的异常处理

Question

我当前安装的Visual Studio 2015不允许在从IDE运行代码时抛出未处理的异常。我想锻炼我的未处理的异常的代码，但我的代码：

Private Sub btnTest_Click(sender As System.Object, e As System.EventArgs) Handles btnTest.Click 
    Throw New System.Exception("An unhandled test exception has occurred.") 
End Sub 

正常运行时才能正常运行，而不是当代码在IDE中被执行。

如何在IDE中调试未处理的异常代码？

我看着调试，Windows，例外设置，但我没有看到办法做我想做的事情。是否还有另一个更全局的设置，允许未经处理的异常而IDE不捕获异常？

我使用ApplicationsEvents.vb到挂钩事件：

Namespace My 

' The following events are available for MyApplication: 
' 
' Startup: Raised when the application starts, before the startup form is created. 
' Shutdown: Raised after all application forms are closed. This event is not raised if the application terminates abnormally. 
' UnhandledException: Raised if the application encounters an unhandled exception. 
' StartupNextInstance: Raised when launching a single-instance application and the application is already active. 
' NetworkAvailabilityChanged: Raised when the network connection is connected or disconnected. 
Partial Friend Class MyApplication 
    Private Sub MyApplication_UnhandledException(sender As Object, e As Microsoft.VisualBasic.ApplicationServices.UnhandledExceptionEventArgs) Handles Me.UnhandledException 
     ExpLog.LogUnhandledException(e, sender) 
     e.ExitApplication = Not ExpLog.InformUser 
    End Sub 
End Class 
End Namespace

分辨率是创建一个测试存根行使被调用由处理程序的代码：

Private Sub Button6_Click(sender As System.Object, e As System.EventArgs) Handles btnMisc_Throw.Click 

    If ExpLog.InformUser() Then 
     MsgBox("Continue") 
    Else 
     MsgBox("End Program") 
    End If 

    ExpLog.LogMsgBox(New System.Exception("test unhandled exception"), "test LogMsgBox()",,, "programmer note") 

End Sub 

这不允许测试处理程序，但它会执行处理程序调用的代码。看着一些老的意见自从五+年前想通了这一点... :(

添加处理，以AppDomain.CurrentDomain.UnhandledException

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load 
    AddHandler AppDomain.CurrentDomain.UnhandledException, AddressOf UnhandledExceptionHandler 
End Sub 

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click 
    Throw New System.Exception("An unhandled test exception has occurred.") 
End Sub 

Public Shared Sub UnhandledExceptionHandler(ByVal sender As Object, ByVal args As UnhandledExceptionEventArgs) 
    MessageBox.Show(CType(args.ExceptionObject, Exception).Message) 
End Sub
