LabView Can't save VI

[cjp1]

I'm trying to save A vi in a project and keep getting the message

LABVIEW: An input parameter is invalid

save error code 0

there doesn't seem to be any reason why it can't be saved.

Are you attempting this programatically?

If so please post an image of the code.

That message usually means we are not using a function properly.

No I am not trying to do it programatically.

The VI is one of many in my project.

When I open it up and try to save it LabeView tells me it can't

Things to check:

• Are you trying to save to a network drive? If so, save to a local directory.
• Are you trying to save to a path that has too many characters? Operating systems have limits on the lengths of paths.
• Are you trying to save to folder with restricted permissions? E.g. on Windows Vista and 7 you are not allowed to save to certain directories without admin rights.
• Can you save the VI if you open it by itself, without opening the project?
• Can you do a Save As?
• Open your most recent backup and see if you can save that. It's possible your VI has become corrupt.
• What changes are you making that's prompting the save? Or, is it prompting you to save simply by opening the VI?
• Are you calling subVIs? Can those be saved OK?
• ...

I moved the project and all the VI's to the local drive and that seems to have taken care of the problem.

Thanks for your help.

Hi there!

I am having the same issue when trying to save a VI.

I will respond the questions posted by smercurio_fc (answers in red):

• Are you trying to save to a network drive? If so, save to a local directory. [answer]: NO, I am saving to local disk.
• Are you trying to save to a path that has too many characters? Operating systems have limits on the lengths of paths. [answer]: Other VIs with longer names in the same directory do not present this problem, so I consider the path name lenght is not the problem.
• Are you trying to save to folder with restricted permissions? E.g. on Windows Vista and 7 you are not allowed to save to certain directories without admin rights.[answer]:Nope.
• Can you save the VI if you open it by itself, without opening the project?[answer]:No.
• Can you do a Save As?[answer]:No.
• Open your most recent backup and see if you can save that. It's possible your VI has become corrupt.[answer]:same problem.
• What changes are you making that's prompting the save? Or, is it prompting you to save simply by opening the VI?[answer]:I have onlu opened the VI.
• Are you calling subVIs? Can those be saved OK?[answer]:Yes and they can be saved normally.

Since you posted in this thread, I assume that your error message is still:

"LABVIEW: An input parameter is invalid | save error code 0"

Is this correct?

At what point do you get that message exactly (right after trying the menu entry? after entering a file name?)

Are the "save" and "save as" menu entries greyed out?

What is your LabVIEW version?

Does the file name contain any unusual characters?

Can you attach your VI?
