Handle invalid characters in filenames during build

NI LabVIEW allows VIs with invalid characters such as "?" in the filename inside an LLB file as shown below:

However when it comes to building a Source Distribution / TestStand Deployment that uses this file it returns an error as shown below:

This inconsistency within LabVIEW is quite frustrating where one part allows invalid characters in the filename and another part will return an error. Since the invalid characters are allowed in VI filenames within LLB files I would suggest that the LabVIEW build tools also handle them graciously.

 

During the build process it could quite easily rename the file "pi40iv Can Connect Channel?.vi" to "pi40iv Can Connect Channel_.vi"  and link the VIs that use it to the newly renamed file. The build tools already contain the ability to rename files by adding prefixes so something like this would not be that difficult.

 

While people may argue to just rename the filename within the LLB and be done with it, the fact that the LLB is a perfectly valid file in the Development Environment but causes problems when trying to do a build is a problem that should be rectified.

 

The LLB in question is one that is not developed by us but is part of a Pickering Driver Installation obtained from the following location:

http://downloads.pickeringtest.info/downloads/drivers/IVI/

Therefore every time we install a new version of the driver we would need to rename the VI filename within the LLB file.

We recently had a similar problem where a project (on Windows) had characters that are not allowed on Linux. When deploying to cRIO, there where no errors, but it didn't work either.

 

+1 for handling this properly.
