Backup command and getting progress like Enterprise/Management Studio

Sorry if this is the wrong place for this, but I couldn't find a better place...

I have a .net application that calls a TSQL command to backup the database when the user clicks a button. I would like to give the user incremental feedback on what's going on.

So I hooked into the connection's InfoMessage event.

It gets called at the end of the command, not during. I read somewhere that you're supposed to be able to add "WITH NOWAIT" to a TSQL command to have it return immediately and then use the InfoMessage for updates, but the Backup command doesn't support it.

I also set a trace on the SQL Server and told SQL Server to backup using Enterprise manager hoping to catch what it was doing special to get these commands, and didn't see anything unique.

Does anyone have suggestions? I really need to show the progress of what's going on.

Thanks!

SqlClient unfortunately does not support retrieving of messages asynchronously during command execution. You can do this however if you use System.Data.Odbc instead. The steps are pretty much the same. This can also be done if you use C/C++ and use ODBC/OLEDB/SNAC.
