Help, open my vi, I can't do it anymore

[David_49]

Hi all,

I'm a stupid boy....

I've increased the history length of my graph up to 4 10^9, and I can't now open my vi anymore (not enough memory on my computer, strange no ?... ).

I'm looking for someone who can open it and change the history length of my graph to 1024.

And no, I haven't made any backup of my vi... I know, I'm stupid.....

Thanks in advance !

David.

Hi David,

"Im a stupid boy" - YES!

"I haven't made any backup of my vi... I know, I'm stupid..." - YES! YES! YES!

Ok, a history of 4×10^9 ~= 4Giga requires atleast 4GB of RAM (for byte values, or 16GB for SGL or 32GB for DBL). I don't think someone here has a LV version capable to support such RAM allocations - I'm happy when I get 1.3GB RAM allocated on a 2GB machine.

So you better start to recode that vi. And do backups this time!

It doesn't open on my machine - it just crashes LabVIEW. But I don't understand. The vi is only just over 100K?

Hi Steve,

the history size of a chart is set to a huge number.

When you open that VI LabVIEW tries to allocate sufficient RAM for the chart history - and simply fails...

Thanks.

David, maybe someone in NI support who knows the internals of LabVIEW code could edit it with some kind of tool to reset the size. It is only a guess but you might want to ask.

Hi Steve,

you see the thread is now 1.5 years old. I think he already created a new version of the VI...

For information, I've recode my vi. I didn't find any solution, even with a powerfull computer...
