Application blocks Ranorex

Post by alasdaircs » Wed Aug 01, 2007 10:04 am

I am automating a commercial application written using the Progress database graphical environment (see http://www.progress.com) from a .NET controller application using (currently) Ranorex 1.1.

The problem is that the code runs fine most of the time, but occasionally the Progress app locks up in such a way that the next call from my controller app to e.g. FindFormTitle, FindClassName or FindChildText gets blocked and never returns, leaving my controller app stuck. Even re-starting the controller app fails, as the first thing it does is a call to FindFormTitle, and so it blocks again.

What I would like is to understand what's happening, and on a practical level for the above calls to use thread callbacks or similar to make them robust in the face of this issue.

I used ProcExp.exe from http://www.microsoft.com/sysinternals to get a stack dump from my controller app and the Progress app when they were "stuck".

Controller App:

Please answer the following questions:

Which Ranorex version do you use, RanorexPro or RanorexFree?
Can it happen, that an application dynamically generate windows on your computer?
Please send us the source code of the controller app.

Progress update...

Post by alasdaircs » Wed Aug 01, 2007 6:05 pm

Hi Jenö,

Currently it's Ranorex 1.1.0 Free on Windows XP Pro. I intend to upgrade to 1.2 Pro once its all working, but 1.2 free is no good because it hits the new action limit.

The bug is in the Progress Application, not Ranorex - its just that Ranorex could possibly be updated to cope with the situation. Unfortunately, I cannot let you have the controlled application for licencing reasons, and you would not be able to reproduce the problem unless you have access to a similarly badly behaved application.

I do not fully understand your question "Can it happen, that an application dynamically generate windows on your computer?". The controlled app is in most respects a basic Win32 app - no clever tricks.

Source code - yes, you're welcome, but its a bit long to paste into a forum - do you have an FTP upload facility or similar, or can you receive large emails with attachments?

Also, I have had to write my own "SelectItemText" menu selection code using Win32 API calls because yours didn't work for me. Firstly, this may be the cause of the problem, and secondly, it may be worth incorporating in your product as an alternative implementation.

Finally, I have tried a workaround today which seems to be working, but as it's an intermittent problem, it's hard to tell...

Thanks for your time so far,
