C updating an access data base
In fact I can update the database while the program is still running, changing Fred to Lisa, and because in this case it always queries the database every time the button is pressed the results will update. We're a friendly computing community, bustling with knowledgeable members to help solve your tech questions.So how do we get this stupid name column out of our table “Employees” of the access database and into a control? One is to connect to the database, another thing is to query the database for the info and lastly we put that info into our source control… Connecting to the database is pretty straight forward and really starts out with picking the right connection object from the System. Since Access can be “accessed” through the OLEDB setup we can use the Ole Db Connection class for that. This is nothing but a string that tells the class where to find the database, what driver (or DSN) to use, any username and passwords to login to the database, and any security features we will need to implement for our access.One great place to find connection string data for tons of different databases is at

When updating just the text fields in the row everything works fine with the following command: db Command.
Command Text = "UPDATE Scan Lib Table SET Regex = '" txt Regex.
I am trying to update an Access database from a Data Grid View.
The loading of the database to the grid works fine. However, to update the database based on changes made to the Data Grid View, I used the command , but depending on the placement (next to this code) the code runs but the database does not update.

However, if you want to get away from the Ole Db Command Builder completely, you can do so (I updated my code above to do just that).
