Hello I am getting the following error from my C# Windows Application:

Error 1 No overload for 'CreateLabelInPanel' matches delegate 'WorksOrderStore.ProcessDbConnDetailsDelegate' H:\c\WorksOrderFactory\WorksOrderFactory\WorksOrderClient.cs 43 39 WorksOrderFactory

I have 3 .cs files that essentially:

1. Opens a windows
2. Has an option for the users to connect to a db
3. When that is selected, the system will go off and connect to the db, and load some data in (just test data for now)
4. Then using a delegate, the system should do soemthing, which for testing will be to create a label. However I haven't coded this part yet.

But I can't build until I get this error sorted.

The 3 fiels are called:

1. WorksOrderClient.cs (which is the MAIN)
2. WorksOrderStore.cs
3. LoginBox.cs

Here's the code for each file:

1. WorksOrderClient.cs

using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using WorksOrderStore; namespace WorksOrderFactory { using WorksOrderStore;

public partial class WorksOrderClient : Form
{   
    LoginBox lb = new LoginBox();
    private static WorksOrderDB wodb = new WorksOrderDB();

    private static int num_conns = 0;

    public WorksOrderClient()
    {
        InitializeComponent();
    }

    private void connectToADBToolStripMenuItem_Click(object sender, EventArgs e)
    {
        lb.ShowDialog();
        lb.Visible = true;
    }

    public static bool createDBConnDetObj(string username, string password, string database)
    {
        // increase the number of connections
        num_conns = num_conns + 1;
        // create the connection object
        wodb.AddDbConnDetails(username, password, database, num_conns);
        // create a new delegate object associated with the static
        // method WorksOrderClient.createLabelInPanel
        wodb.ProcessDbConnDetails(new ProcessDbConnDetailsDelegate(CreateLabelInPanel));
        return true;
    }

    static void CreateLabelInPanel(DbConnDetails dbcd)
    {
        Console.Write("hellO");
        string tmp = (string)dbcd.username;
        //Console.Write(tmp);
    }

    private void WorksOrderClient_Load(object sender, EventArgs e)
    {

    }

}

}

• and LoginBox.cs

  using System; using System.Collections.Generic; using System.ComponentModel; using System.Drawing; using System.Data; using System.Linq; using System.Text; using System.Windows.Forms;

namespace WorksOrderFactory { public partial class LoginBox : Form { public LoginBox() { InitializeComponent(); }

    {
        this.Visible = true;
        this.Show();
        //usernameText.Text = "Username";
        //new Font(usernameText.Font, FontStyle.Italic);
    }

    private void cancelBtn_Click(object sender, EventArgs e)
    {
        this.Close();
    }

    private void loginBtn_Click(object sender, EventArgs e)
    {
        // set up a connection details object.
        bool success = WorksOrderClient.createDBConnDetObj(usernameText.Text, passwordText.Text, databaseText.Text);

    }

    private void LoginBox_Load_1(object sender, EventArgs e)
    {

    }


}

}

Any ideas??
