问题 I'm inserting a few rows in a table via OleDB, and select instantly the inserted row. I can't retrieve the row in this way, i have to wait for approx. 3-5 seconds. And then the inserted row appears in the table. I observed this behavior in the database itself, i inserted the row via OleDB and watched the opened table in Access. The row appeared 3-5 seconds later in the table. Does Access buffer rows? Do i have to send a flush or commit, etc. via OleDB ? Any suggestions would be very helpful.

问题 I have a Foxpro .DBF file. I am using OLEDB driver to read the .DBF file. I can query the DBF and utilize its .CDX index file(cause it is automatically opened). My problem is that I want to query it with the .NDX index file (which is not automatically opened when the .DBF is opened). How can I open the .NDX file in C# using OLEDB driver cause the DBF is really big to search for a record without the index? Thanks all! Here is the code I am using to read the DBF.

SqlConnection connection = (SqlConnection)connections[_connectionName].AcquireConnection(transaction); Now if I have the OLEDB connection (instead of ADO.NET), I'd like to handle that situation in this
