Vb.net Connection String for Ms Access Database

问题:

What is the connection string for connecting MS Access 2010 (.accdb) database in VB.net.

回答1:

connectionstrings.com is a wonderful thing:

Standard security

Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\myFolder\myAccess2007file.accdb;Persist Security Info=False;

With database password

This is the connection string to use when you have an Access 2007 database protected with a password using the "Set Database Password" function in Access.

Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\myFolder\myAccess2007file.accdb;Jet OLEDB:Database Password=MyDbPassword;

Some reports of problems with password longer than 14 characters. Also that some characters might cause trouble. If you are having problems, try change password to a short one with normal characters.

DataDirectory functionality

Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\myAccess2007file.accdb;Persist Security Info=False;

You may use Server Explorer of Visual Studio to get the connection string or take a look at the connection string.

www.connectionstrings.com

this is a good site for connection strings for almost any application

回答4:

Did you connect to the database by using 'Tools->Connect to database' ?

If you have already done the above, try this:

Go to server explorer. And select connected database -> In its properties there is a connection string -> Copy it and paste into your code.
