Creating a connection to MS Access with Visual Studio 2005

Hello and thank you for reading my question. I'm just getting started with .Net, and I need to relearn a great many things. The code below relates to a log on form. When I enter values for the user name and password and then press the button, I get an error with the details below. Would someone be kind enough to point me in the right direction?

 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        If Me.txtUserName.Text = "" Then
            MsgBox("Please Enter User Name")
            Me.txtUserName.Focus()
            Return
        End If
        If Me.txtPassWord.Text = "" Then
            MsgBox("Please Enter a Password")
            Me.txtPassWord.Focus()
            Return
        End If

        Dim strSQL As String
        Dim strConnection As String
        Dim objConnection As New OleDb.OleDbConnection()
        strConnection = "Provider=sqloledb;Data Source=C:\Users\Patrick\Desktop\Test\dbTest"
        objConnection.ConnectionString = strConnection
        objConnection.Open()

        Dim objCommand As New OleDb.OleDbCommand

        strSQL = "SELECT intUserID, strUserName, strPassword " _
                & "FROM tblUsers " _
                & "WHERE strUserName=@strUserName AND strPassword = @strPassWord;"

        With objCommand
            .Connection = objConnection
            .CommandType = CommandType.Text
            .CommandText = strSQL
            .Parameters.Add("@strUsername", OleDb.OleDbType.VarChar, 25).Value = Me.txtUserName.Text
            .Parameters.Add("@strPassword", OleDb.OleDbType.VarChar, 25).Value = Me.txtPassWord.Text
        End With

        'Once I fix the above, I'll do something here.
        objConnection.Close()

    End Sub
