Callback or other method for when sequence file is saved?

[Bob Rafuse]

Using TestStand 3.0, is there a way to process a test sequence file
automatically when the file is saved in the Sequence Editor? I would
like to perform some custom sanity checking (and possible other
actions) on the sequence file when it is saved. Right now I have the
checking done via a Tools menu item, but this is proving inadequate as
the users often fail to perform the check.

Is there a callback or other hook available that allows this?

Thanks,

There are no ideal hooks to do this. The only callback that could be used is SequenceFileUnload, but each sequence file would have to define the callback and invoke a tool in a shared sequence file. You would probably want to use PropertyObjectFile.ChangeCount to determine if the files was modified since it was loaded and only do your checking if true. Minimally you could warn the user if something was not correct when the file was unloaded from memory.

Thanks. The SequenceFileUnload option isn't really a viable fix for
this problem as as I run into the same problem as the Tools menu item:
the users will forget to add the callback to their sequence files. I
was hoping there was some other hook I was missing.

On a related note, is th
ere a repository for "wish list" items for
future versions of TestStand? The big "wish list" feature I think
would benefit all (not to mention solve my problem 😉 would be the
ability to create a new sequence file from a template (so new sequence
files can be "preloaded" with specific FileGlobals, Locals,
implemented callbacks, etc).

Thanks,
