I did a sbmerge on a project a couple o'days ago.
It needed a new odbc-source so I included odbcad32.. ill post the complete entrypoint here, its a nice tip

http://Virtual ODBC Administration.exe
Source=%SystemSystem%\odbcad32.exe
Shortcut=<Whateveryourmaincontaineris>

Anywho, the new ODBC-source (user) was then marked with isolationmode "sb_only" in hkcu.txt. When was this isolation mode introduced? (im using 4.0.3)
I thought that then this new odbc-info would only be read if it was located in the apps sandbox (for some reason) but no.
So whats the advantage with sb_only versus Full?

In my case the app had to be locked to a special odbc-source, pointing to a "test-database", therefore its critical that no physical-odbcsettings can be read since the production database looks the same/same credentials.

full isolation means "probe sandbox, if you don't find a value then probe the read-only layer (package contents)".
sb_only isolation means "probe sandbox only". This isolation mode only occurs if you delete a subkey at runtime, in such a case we should no longer probe the read-only layer because any values that were originally in the package should be gone (deleted). So.. the sb_only isolation mode should only exist in the sandbox.

isolation_full HKEY_CURRENT_USER\Software\ODBC
isolation_full HKEY_CURRENT_USER\Software\ODBC\ODBC.INI
isolation_sb_only HKEY_CURRENT_USER\Software\ODBC\ODBC.INI\Extens - Testdatabas
Value=Driver
REG_SZ~%drive_p%\ADM\IST\ist\dbodbc9.dll#00
<lots of more properties for the source>

the client hasn't run this app before, therefor they have no SB.
So this line doesn't seem to be marked as deleted?

Cannot tell why it was made sb_only if it was not deleted but it origins from the sbmerge process.

Yes it did. I changed the iso-mode to Full just to be sure.
Thanks.
