C# + Access Database

This may be an easy question, but it's been so long since I've dealt with Access that I've been beating my head against the wall trying to get a simple query to work with C#.
The Query is "SELECT # FROM Personnel WHERE (myName = \"Test\") AND (myPassword = \"test\")
I can run the query directly from Access and it returns the row I want, but when I run it through the code, I get the "ODBC Microsoft Access Driver - too few parameters. Expected 1" error.
I'm accessing the database through a DSN.
Any ideas why this will not work?

FYI - I'm working with VS 2008...

here http://www.connectionstrings.com/access you can find how to connect to access, but why do you choose to do this with odbc ?

I'm using ODBC just because that's what I've always used when connecting to an Access database. However, the last time I did that, I was using VB.NET 2003, and now I'm coding in C# 2008...
I've been to ConnectionStrings.com, and I'm fairly certain that the connection itself is ok. Here is the steps I use:

private OdbcDataAdapter adapter;
private OdbcConnection conn;
private OdbcCommand com;
public DataSet ds = new DataSet();
public int numResults;

try
{
conn = new OdbcConnection(connectionString);
adapter = new OdbcDataAdapter(sql, connectionString);


adapter.Fill(ds,"Results");

numResults = ds.Tables["Results"].Rows.Count;
results = ds.Tables["Results"];
}

** connectionString = "DSN=myDatabase" - this DSN is set and working correctly
** sql = Select string listed above
** The program always crashes on the "adapter.Fill(ds, "Results") section

i use this whith access

Code:

---

using System.Data.OleDb;
...             
                          try
                {
                    OleDbConnection thisConnection = new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=database.accdb;Mode=ReadWrite;Jet OLEDB:Database Password=mypassword;");
                    OleDbCommand thisCommand = new OleDbCommand("your query here", thisConnection);

                    thisConnection.Open();
                    OleDbDataReader thisReader = thisCommand.ExecuteReader();

                    while (thisReader.Read())
                    {
                        //this will read the value thisReader.GetValue(0).ToString()
                    }

                }
                catch (Exception ex)
                {
                    MessageBox.Show(ex.Message.ToString(), "ERROR", MessageBoxButtons.OK, MessageBoxIcon.Error);
                }

Thanks for your help; that code works.
