I am using ADX to display a WPF control (hosted in an ElementHost, which is in turn hosted in an ADXForm) in the bottom navigation panel, and also as the "web view" of a particular folder.
I left my computer unattended for 30-40 minutes and the following exception was reported by ADX;

The rendering of Outlook was totally trashed after this, with black boxes appearing and UI elements not being rendered correctly.
Can you help me diagnose the cause of this exception?
Thanks,

Hello Chris,
We would need to reproduce the issue.
Did the forms execute some code while you were away? Is there a possibility that the computer "went to bed"? Any screensaver?

Unfortunately I've only seen this once, and not in a test harness add-in or anything similar, so I'll have to create a dummy add-in to try and see the same behaviour.
My add-in was doing some background thread work while I was away. Do you think that if that process used up all the working memory, that ADX might react in the way it did when trying to re-render?
Also, the screensaver did kick in, but the computer didn't "sleep" - that's disabled. |

Hi Chris,
I'm very sorry for leaving your message non-replied; I suppose I overlooked it somehow.

No. If there's a problem in inter-thread communications, you can get any sort of errors generated/shown far from the real cause of the problem.

That's no problem Andrei!
The problem has never occurred again, so I'm just going to keep an eye on it for now.
Thanks again. |
