Hi Billy;

  Have you checked the MS-Windows Application Logs to see if there are any corresponding mni-dumps produced when your App crashes?

Also ... were there any recent Windows updates , DBMS or DB Client software updates when this started happening?

Regards ... Chris

Hi Chris,

No I did not check any windows logs.  As for windows updates, I do not know.  As I said, I we really dont control that and sometimes things get pushed down without anyone's knowledge.  I doubt the DBMS got updated.  We are able to connect to the database.  It is just crashing shortly after the datawindow displays the data.

I will get the windows logs checked.

Thanks

Billy

Yes, but it is happening on any form she opens once connected to the database, so not isolated to a particular table.  I just dont know the internals of PB well enough to know if there is anything written to the local computer (for caching/datawindow result sets) that she may not have write access to any longer.  That seems more likely.

Hi Chris,

I setup tracing and created 2 files.  One on my computer  and one on her computer  (same executable and files).  I named  the files good_dbtrace.log and crashed_dbtrace.log.  Like I said, once the screen on the "crashed" file, the application closes.  No error, nothing.  As you can see, they look very similar, but at the end of the "good" file there are a few more statements because I closed the application out normally (below).

Again, I dont think it is a PB issue, but if PB writes any files to the workstation, that may be it.

Hi Chris,

Here is a question from our desktop support that I cannot answer.

Billy, does this program cache anything in the user appdata folders?  If it’s following Laura to other computers, it sounds like a roaming profile issue; however, we need to know what folders it uses to try and clear them to resolve it.

Appdata or a registry value are the only things that replicate between devices, I’m not sure what else could do it unless she’s running it from onedrive or something and there’s a lock file being generated somewhere that’s not releasing properly.

"goes to any screen that has a datawindows, the application closes. "

no error, just disappears?  that sounds like anti-virus.

does the datawindow do a retrieve and then it closes, or does it close prior to the retrieve (she has to click something to make it retrieve)? 

If it closes when a retrieve is done, then it could be anti-virus software.  

Hi Billy;

  I cannot answer these questions either as I do not know how your App is coded. You might want to run your all from the PB IDE via the Debugger & trace the section where it crashes to see what folder(s) the app is trying to Read From and/or Write To to answer your operations team.

PB doesn't write to the user's AppData folder unless the developer has explicitly written code to do so. It sure sounds like this issue is related to the user's permissions (or drive mappings, etc.) having been changed. The network admins should be able to come up with a quick test to rule that out.

Hi,

When the crash happens, have you checked the windows event viewer?
