Disable IE script debugging via IE control

Question

Bleh; Knowing how to ask the question is always the hardest so I explain a little more.

I'm using CAxWindow to create an IE window internally and passing in the URL via the string class argument:

CAxWindow wnd;
m_hwndWebBrowser = wnd.Create(m_hWnd, rect, m_URI, WS_CHILD|WS_DISABLED, 0);

It's part of an automated utility for anyone to get images from their "internal" javascript-based apps; the issue is that some people try getting images from their apps that have lots of errors; The errors fire off the IE debug window and my capture utility sits waiting for input.

Initially I thought I could disable the debugging ability via IE in windows however the process that Apache runs in and hence my App is via the SYSTEM account; not sure how I'd change the debugging options without hacking the registry.

Answer 1

Would it be possible to just wrap everything in a try / catch in the javascript code that is being displayed in the CAxWindow at that URL? That would allow you to squelch all the errors, hopefully.

Answer 2

Link your app with detours or other API hooking library, hook RegQueryValue function from advapi32 and return "yes" when IE queries value for registry key "HKCU\Software\Microsoft\Internet Explorer\Main\Disable Script Debugger".

Answer 3

I found some projects on CodeProject that does something similar...

And also an MSDN article regarding web browser customisation:

I found that what I was after was two interfaces called: IOleCommandTarget and IDocHostUIHandler; I needed to override the UI handler and interpret the Script exception messages and respond with a "false" to indicate I didn't care about the error;

Unfortunately I spent waaaaay too much time getting my head back into COM and trying to get their god awful system set up that I wasn't able to finish it and after a discussion with my bos regarding spending more time trying to get this working or just disabling debug in IE; we chose the later.

3 Words; I hate COM :-p (the smilie doesn't count)

I think the path I was on would solve the issue I had and my response can contribute as an "answer"; sorry if it's not what you're looking for.
