Efficiently Load A Microsoft Access (Jet) Database Table?

Jun 21, 2010

I'm attempting to create and populate a table in a new Microsoft Access (Jet) database using VB.Net 2008 Express under Windows XP Pro SP3. The database and table are being created properly, but loading the table proceeds VERY slowly. When I am loading the table, no complicating factors that might impact performance, such as indexes or table relationships have been defined. The table to be loaded is made up of relatively short rows consisting of three single byte columns, and one (four byte) integer column. I am loading approximately 16 million rows, and this is literally taking hours, while the same data can be interactively imported into Microsoft Access from a .csv file in minutes. I am trying to batch load the rows, 64K rows at a time, in order to avoid the overhead of individually transacting/committing each row individually, but suspect that I must not be doing something right. Key code that I am using for this process is provided below.

Connect To Microsoft Access Database Using "Microsoft DAO 3.6 Object Library"?

May 3, 2012

I have vb .net windows form application that I want to connect to Microsoft access database using "Microsoft DAO 3.6 object library". My problem is that when I go to Project tab -> Add reference -> COM tab, there should have been "Microsoft DAO 3.6 Object Library" on the list, but for some reason It's not on the list. Then I googled, and found out that the location of "DAO360.DLL" is "Program FilesCommon FilesMicrosoft SharedDAO". After clicking on Browse tab, I browsed to that location, and I guess I added reference on another way.This is the code that I used before for connecting to Access, but for some reason It doesn't work this way on this PC.
