Trouble deleting log files

[Testing_Guy]

I have been having trouble deleting log files in SE.  I made the mistake of deleting a bunch of files directly from the SignalExpress Data folder rather than removing them via the log files window in my SE project.  Now, every time I open the project, SE notifies me that the project is linked to the following deleted files and that I need to restore them if I want the project to function properly.  The logs are still listed in the log file window within the project.  If I try to delete these files, SE freezes up.  Does anyone know how I can delete these from the project without having to start from scratch?

Thanks!!

Hello JB,

I attempted to recreate this situation by creating a project with several log files, saving the project, and then deleting the log files manually as you described. I wasn’t however able to make SE freeze up when I deleted the corresponding entries in the Log files window.

What version of LabVIEW SignalExpress are you using? When you deleted the log files manually, did you delete the entire folder or just specific files?

When you choose to delete a log file in SignalExpress it asks if you would like to delete it from the project or from the project AND the hard drive. Does it freeze for both of these options?

If you would like to post the project I can take a look at it and see if I can reproduce the problem.

HI Chris,

I just tried to reply to your message, but I am not sure if it went through.  My log file is pretty large ~2.5 mb, so it might just be taking a while to post.  Either way, here it is again. 

I am attaching the project file.  I am using a different computer than the one that I used to geernate the log files, so there are no files or folders.  I have all of the data that I need exported to a text file, so I am not worried about loosing anything.  Can you take a look and see if you notice anything that might help.

Also, I am wondering if there is anyway to lock the number of significant digits on the numeric displays.  I am displaying numeric load indicators in kips and every time I approach zero the display starts reading 850m or 280u.  Trying to explain what a milli-kip is starting to wear on me.  Any thoughts?

Thanks!!

Hello JB,

I went over your project that you posted and couldn’t find any particular reason for it to be freezing when you delete the files. I was able to delete them for you so hopefully that will alleviate your troubles. I would suggest in the future that you delete them through the log management window instead of manually removing them.

As for your question on how to lock the precision of your indicators, there is an option available which you currently have selected which auto-scales the display. As a result when you approach zero it will scale down so that you can still see the changes in the data. If you know the expected range of your measurements and don’t want to “zoom” in when the data approaches zero you can disable the auto-scale feature. This can be done by the following:

Right click on your target axis -> Select Properties -> Select the Scales tab -> Uncheck auto-scale

You will then be able to enter the max and min values for your range on that axis.

Attached below is your project without the “ghosted” log files. Hope this helped!

Thanks Chris,

I actually went ahead and rebuilt the project to get rid of the log files.  Did it take your machine a LONG time to delete them?  Even after I rebuilt the project I am still running into "freeze up" problems when I try to start or stop a log file, deleting the logs, and adding limit steps.  I am going to try to re-install SE this morning, but I have seen this same behavior on two separate computers.  The one that I am running now has:

Intel Core2Duo @ 3.00 GHz

2.00 GB of RAM

Three 160 GB HD's in RAID5 ~280 GB total

Running Windows XP SP2 & Labview 8.5 & SE 2.5 Full

I would think that this should be plenty of machine to do what I need.  I have attached the most recent version of the project.  If you try to add a ninth analog channel and adding a limit step and try to choose this new channel as the source for the limit, it runs the CPU % to 100 and stays there.  The "idle, run" box says running once if that helps.  If I get impatient and shut down SE through task manager I am no longer able to open the project (presumable because it was still in the middle of adding/configuring the step when it was closed).  This is obviously less than ideal.

As for the unit scaling, it is the numeric displays that I am having the hardest time looking at.  I haven't been able to find a way not to "auto scale" the large display indicators... thoughts?  This is obviously secondary to being able to actually run/edit the project without it crashing.

THANKS again for your help!!

Hi JB,

I've opened up your earlier project and deleted the log files as done by Chris in the previous post.  I do want to add that it did take aprox 15-45 seconds to delete a specific log file. I'm not sure if you are seeing much longer times, but this is to be expected with larger log files.  

As for your other concerns, I believe you have opened a service request with us and are dealing with these concerns over the phone.  We will do our best to update this thread with the resolution.

Thanks,
Paul C.
