Unicode and threads

Hello,

I wrote multi-threaded application.

I use marshaling of DataSetProvider.IAppServer interface form main thread to worker threads.

If UseUnicode = False then all works ok.
If UseUnicode = True then I got Acces Violation error

Any clues?

Please, send us a complete small sample at dbxsda*crlab*com to demonstrate the problem, including script to create and fill table.
Also supply the following information:
- exact version of DbxSda.
- exact version of your IDE;
- exact version of SQL server and client.

I found a solution.

There was a query with 'case'. I surrounded it with 'cast'.
It works ok now.

Maybe null or some other value is typed in another way when UseUnicode is set to True/False. (There aren't any nvarchar fields returned in this query).
