Debugging javaScript in Visual studio. First chance exceptions

Question

I have a project in visual studio (C++). The front end of the project is written in javaScript, it's a simply GUI for the C++ running in a chtmlview window.

When the project is run in visual studio, in debug mode, I'm getting the following:

There are literally pages of this spat out of the console. I'm finding it very hard to find a way to debug the code. The fact that it must run in a chtmlview window, (Rather than something lovely like Chrome, with its beautiful debugging abilities... "Yes, Microsoft... You let me down), makes it even harder. I'm using the latest version of my jQuery in my project, apart from that I have a minimum amount of Try/Catches.

Anyone pointed from people who have had to debug javaScript running in chtmlview, that would be much appreciated.

Other symptoms include the window running horribly slowly after being left to run over night.

(Note: I'm basically the script monkey on this project, have little/no input on the C++ side of things but have recently rewritten all the javaScript; So you can see my these exceptions are embarrassing me!).

In Visual Studio 2015, you can configure which exceptions you want the debugger to handle.

In following link you can see, how to configure it: http://blogs.msdn.com/b/visualstudioalm/archive/2015/01/08/understanding-exceptions-while-debugging-with-visual-studio.aspx

I hope it can help you or anyone.
