Edit: Visual Studio 2015's new exception window is so much faster than
the old dialog that I no longer care as much about using a keyboard
shortcut for it.
Is there a macro or keyboard shortcut that will toggle "break when an exception is thrown" without using the GUI?
Opening the dialog with ctrl+alt+e and checking the "Common Language Runtime Exceptions" "Thrown" box then clicking OK is simple enough, but this is something I do a lot. I would rather have a keyboard shortcut for this.
This question is a duplicate of
Any have a Visual Studio shortcut/macro for toggling break on handled/unhandled exceptions?
However, the poster accepted an answer that doesn't really work, and I would really like an answer that does work.
The answer in the duplicate question is not acceptable because it toggles only one specific exception, not the entire CLR group.
"Well write a loop then." you say. But not so fast! Someone tried that already and it was uselessly slow. (Yes I've verified that its slow on my system as well.)
So the challenge is to use a macro to toggle the entire CLR Exceptions category in less than 1 or 2 seconds.

回答1:
I have created a free Visual Studio extension that can do that reliably: Exception Breaker.
It uses undocumented IDebugSession2.SetException
call that is very fast: all exceptions are set/unset in 20 to 60 milliseconds.
回答2:
Very similar to the other answer, but there is a special ExceptionSetting for the group.
Dim dbg As EnvDTE90.Debugger3 = DTE.Debugger
Dim exSettings As EnvDTE90.ExceptionSettings = dbg.ExceptionGroups.Item("Common Language Runtime Exceptions")
Dim exSetting As EnvDTE90.ExceptionSetting
Try
exSetting = exSettings.Item("Common Language Runtime Exceptions")
Catch ex As COMException
If ex.ErrorCode = -2147352565 Then
exSetting = exSettings.NewException("Common Language Runtime Exceptions", 0)
End If
End Try
If exSetting.BreakWhenThrown Then
exSettings.SetBreakWhenThrown(False, exSetting)
Else
exSettings.SetBreakWhenThrown(True, exSetting)
End If

Here's Bryce Kahle's very useful macro blindly updated to run in VS2010:
Sub ToggleExceptions()
Dim dbg As EnvDTE100.Debugger5 = DTE.Debugger
Dim exSettings As ExceptionSettings = dbg.ExceptionGroups.Item("Common Language Runtime Exceptions")
Dim exSetting As ExceptionSetting
Try
exSetting = exSettings.Item("Common Language Runtime Exceptions")
Catch ex As COMException
If ex.ErrorCode = -2147352565 Then
exSetting = exSettings.NewException("Common Language Runtime Exceptions", 0)
End If
End Try
If exSetting.BreakWhenThrown Then
exSettings.SetBreakWhenThrown(False, exSetting)
Else
exSettings.SetBreakWhenThrown(True, exSetting)
End If
End Sub

First i initalized a timer an then i call the command Exception.Debug.
The timer hit, when the modal dialog is openend.
If you use Win 7 with deactivated UAC SendKeys with ALT-Key will fail...i don't know why.
i played a little bit...try this (VS2010 EN):

Well, I wrote a VS2008 C# based plug-in that toggles the 386 exceptions, and it takes about 1 second per state toggle. I'm assuming that's due to COM inter-op.
This was based on the VB/macro code in the one of your links. I could not find an easier C++ method (but not ruling it out).
The next level would be to make a plug-in that has a keyboard binding, that then opens the Exceptions UI and then "clicks" the correct tick box for you.
Good luck.

You could use a tool like AutoHotKey to create a recorded script (mouse clicks or key presses) and then assign it a hotkey that will play it back when pressed...

Just offering some info I found on this (here) as I was scouring the net in my futile attempt to help...
Someone else posed this same question and it was responded to by Gary Chang from MS Support, here's the quoted response:
I am afraid the Macro code cannot
manipulate the operations on the
Exceptions dialog box...
It's important to note that this posting is from December of 2005 so this response may no longer be accurate; either way, thought I'd throw it out there.
回答8:
The suggestion of setting the special ExceptionSetting for the group does indeed toggle the state of the top-level checkbox. However, it doesn't seem to toggle the individual Exceptions below it in the tree, and moreover, my process does not stop when such exceptions are thrown as it does if I manually check the top-level checkbox. Do you see different behavior?

My macro to ignore current CLR exception in runtime. It works like a button 'disable catching this exception type' when an exception pops at debug-time.
