Cannot open VI file in edit mode.

[Minguccio]

I cannot open a VI project that I was working on. Every time I try to open the file it gives me a message that "not enough memory to complete this operation".

This is a large project and I need to be able to access the block diagram.

This happens when I try to open it in edit mode.

Thanks.

Typically a VI that is not running is is "edit mode". (unless you press ctrl+M). Do you have problem with "edit mode" in general or only when you try to view the diagram?

Is this one big VI or can you isolate the problem to a subVI? How big is the VI? Can you attach it?

It is possible that the VI is corrupt.

What is your LabVIEW version?

[Minguccio]

When I double click on the .vi file it gives me the message of "Not enough memory to complete this operation". Afterwards the front panel shows up but not editable.

My version is Labview 8.0 Full Development System.

I was working on the vi and then Labview crashed and after that I can't open the file any longer. I don't have a back up of the project. Is there anything that I can do?

Thank you.

Minguccio,

I've done some poking around and may have found some useful information. This error will ocurr if you have too many (and I mean a ton) of controls on the front panel. I haven't heard of this error since LabVIEW 5.1 though and we've upgraded the number of controls you can have on your front panel since then. However, try deleting some controls from your front panel to see if this helps out.

My investigation also lead me to tcp errors. Are you using tcp\ip anywhere in your programming? I found this discussion that may help out if that's the case.

Let us know what you find.

Chris,

I don't seem to have a ton of controls in my project and I am not using any tcp/ip processes.
I would like to delete a few controls but I cannot open the project in edit mode and therefore cannot access neither the block diagram nor the controls window.

Any other suggestions would be greatly appreciated.

Thank you.

Minguccio,

Go ahead and post the top level vi that seems to be giving the trouble (I'm assuming that you have a "Top VI \ SubVI" structure).

Chris,

Thank you for your time that you have taken to answer my messages.

I found a backup copy of the project and was able to resume my project without too much trouble.

Thanks.
