ADO.NET Errors

I have several database access classes that prepare SQSL statements using the ODBCCommand object.  Whenever the client needs data, these prepared command objects are executed using an OdbcDataAdapter to fill a DataSet.  I can execute the same ODBCCommand over and over again, sometimes it works, sometimes it does not and it never happens at the same time.  On error I get is "Service already in progress" on the line of code that uses the ODBCDataAdapter to fill a data set.  Sometimes I get an error "The connection is dead."

Can anyone help???????

Sometimes I fine that OleDb works better.

My suggestion would be to use a managed .NET provider to connect to Informix, versus using ODBC.  You will be much happier with the performance.

The solution wound up being to check a check box under the advanced options of the odbc driver in question to "Open-Fetch-Close Optimization".  I still do not understand why this has appeared to fix the problem.
