I want to make a simple application for an exercise, so it could be nice to connect to a simple database like Access (.accdb)
My program looks like this:
using System;
using System.Collections.Generic;
using System.Data;
using System.Data.OleDb;
using System.Linq;
using System.Web;
namespace myProject.Account
{
public class DbManager
{
private OleDbConnection _dbConnection;
public void OpenDbConnection()
{
_dbConnection = new OleDbConnection {ConnectionString = GetConnectionString()};
}
private string GetConnectionString()
{
return "Provider=Microsoft.ACE.OLEDB.14.0;Data Source=exercise1.accdb";
}
public void CloseDbConnection()
{
_dbConnection.Close();
}
public void GetUser()
{
DataSet myDataSet = new DataSet();
var myAdapptor = new OleDbDataAdapter();
OleDbCommand command = new OleDbCommand("SELECT * FROM tblUser", _dbConnection);
myAdapptor.SelectCommand = command;
myAdapptor.Fill(myDataSet, "tblUser");
}
}
}
I using Visual Studio 2010. When I test my application by using the built in debug mode "Start without Debugging" (CTRL+F5) I get this error:
The 'Microsoft.ACE.OLEDB.14.0' provider is not registered on the local machine.
I have tried to download and install "Microsoft Access Database Engine 2010 Redistributable" (64 bit) from Microsoft omepage: http://www.microsoft.com/download/en/details.aspx?id=13255
Unfortunately it sah not solved the problem. I still got the error when the myAdapptor.Fill() is executed. What is wrong?
You need the Access 2007 Runtime.
