Can't you seeeee? "Can anyone help me get started?"... He has no clue! And he's too lazy to Google it. Why should anyone Google? Codeproject is there!

Please tag this question correctly. We don't know as of yet what kind of application you are planning.
Is it a "Windows Forms" application or a ASP.NET application.

Please tag your question appropriately! Thanks for your cooperation.

It's realy not clear.
What did you find about it? And what's the snag?

Here's some code I used, works perfect for me!
I'm using Microsoft Access 2007 and Visual Studio 2010 Ultimate on Windows 7 Ultimate x64.

You'll need to change the connection string and path to the actual database file

Code:
Add this in your Using Section:

using System.Data.OleDb;

string ConnStr = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=G:\\MedDesk\\Login.accdb;";
            OleDbConnection MyConn = new OleDbConnection(ConnStr);
            try
            {
                MyConn.Open();
                string StrCmd = "SELECT User, Pass FROM LoginTable WHERE User='"+user.Text + "' and Pass='" + pass.Password + "'";
                OleDbCommand Cmd = new OleDbCommand(StrCmd, MyConn); ;
                OleDbDataReader ObjReader = Cmd.ExecuteReader();
                if (ObjReader != null)
                {
                    new MainWindow().Show();
                }
                ObjReader.Close();
                MyConn.Close();
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }

1) Add a new form to your project.
2) Add two labels, two textboxes, and two buttons.
3) Change the label texts to "Username" and "Password"
4) Change the textbox names to "tbUsername" and "tbPassword"
5) In the properties pane for the "tbPassword" textbox, set "UseSystemPasswordChar" to true
6) Change the two button names to "butOK" and "butCancel"
7) In the properties pane, set butOK.DialogResult to "OK" and butCancel.DialogResult to "Cancel"
8) Double click the OK button.

Show the form in your code in the usual way. If the DialogResult is OK, check the two text boxes against your database. If they are not the same, show the form again.
