10.2 lib to 10.1

[Mike Matthews - Omnis]

Don’t forget to add the removal of code folding.  UK support put that feature in for me for doing just this process of downgrading.

Ah yes I dusted off the old ‘downgrade’ library and adjusted the byte value accordingly :)

Many thanks

Hello Andy,

A few things you can do:

1 Remove all code folding

Do $libs.$makelist($ref.$name,low($ref.$pathname)) Returns lvLibsList
For lvLibsList.$line from 1 to lvLibsList.$linecount step 1
Do $libs.[lvLibsList.C1].$classes.$sendall($ref.$removecodefolding()) ## Remove Code folding from each library.
End For


2 Change first bit of library down by 1

Do $libs.$makelist($ref.$name,low($ref.$pathname)) Returns lvLibsList
Calculate lvByte as '7' ## Converts Library Back from 10.2 so that it can be used with Studio 10.1

For lvLibsList.$line from 1 to lvLibsList.$linecount step 1
Calculate lvPath as lvLibsList.C2
WriteBinFile (lvPath,lvByte,0,1) Returns lvError ## This changes the first byte of the file so it can open in v10.1


If lvError<>1
OK message Alert (Sound bell) {Could not update file: [lvLibsList.C1] Operation Aborted!}
End If


End For

Can anyone remind me of the process to downgrade a 10.2 lib to 10.1 ? Just spent a heap of time working on a 10.2 lib for a client still on 10.1 :)
