Hi everyone!

What is the best way to obtain a list of user defined tables?
I would like to add them to a combo box in my program.

Here is what I have so far:

SqlCeCommand getTables_comm = new SqlCeCommand("SELECT table_name from user_tables", conn);

getTables_comm.CommandType = CommandType.Text;
getTables_comm.ExecuteNonQuery();

conn is defined as the connection to the database.

The following error is what I'm receiving as a result of running this code:

An unhandled exception of type 'System.Data.SqlServerCe.SqlCeException' occurred in System.Data.SqlServerCe.dll.

This error is pointing to the ExecuteNonQuery command.

Does anyone have any advice as to what I'm doing wrong and how to resolve this sqlserver error message?
