View 2 RepliesFrom within my VB.Net program, I would like to write to one specific column of a row in a table in an SQL database, given the row's primary key. What is the lowest-overhead means of doing this? I understand how to create a table adapter, fill a datatable, write to the datatable and then update the database.

View 2 RepliesI have two Access database, say database One.mdb and Two.mdb. I want to use VB2005 to export tblCustomer from One.mdb to Two.mdb, and replace the existing tblCustomer in Two.mdb, during run time. I basically want to simulate the export function that is available in MS Access (which can export one table from one Access database to another) with VB2005 during run time. I can think of a way by querying the table to a dataset and then delete everything on the other database before filling the table in that database with the dataset. However, there should be something simpler and faster than that, shouldn't it? Any idea?
