Why is this not working? Does not execute code?

I am trying to have a textBox auto complete with values from a database. When i bullet test the code will walk though until the if statement in the function below. Could some one please tell me why my code wont execute after that if?

I am trying to run the following but it keeps jumping out before the if:

public AutoCompleteStringCollection AutoCompleate(string dataBase, string procedure)
{
        AutoCompleteStringCollection namesCollection =
            new AutoCompleteStringCollection();

        SqlDataReader dReader;
        SqlCommand cmd = new SqlCommand(procedure, con);
        cmd.CommandType = CommandType.StoredProcedure;
        con.Open();
        dReader = cmd.ExecuteReader(); // This is the last place my bullet check 
                                       // gets before it hop's out!
        if (dReader.HasRows == true)
        {
            while (dReader.Read())
                namesCollection.Add(dReader["SystemUser"].ToString());
        }
        con.Close();
        dReader.Close();
        return namesCollection;
    }

Additional information, but please focus on the above!


Please ask if you need any info. :)


The Call to the above:

textBoxUser.AutoCompleteMode = AutoCompleteMode.Suggest;
textBoxUser.AutoCompleteSource = AutoCompleteSource.CustomSource;
textBoxUser.AutoCompleteCustomSource = 
    DatabaseService.Instance.AutoCompleate("AuditIT", "AutoCompleate");

Stored Proc:

USE [AuditIT]
GO

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
--Allow textboxs to have a autocomplete
 ALTER procedure [dbo].[AutoCompleate] 
 as

 Select distinct SystemUser from SchemaAudit
             order by SystemUser asc

There is an unhandled exception when you try to hit the database. Try to refactor the code as this:

try{

if (dataBase.Length > 0) { procedure = dataBase + ".." + procedure; } //Set procedure to DBNAME..ProcedureName

SqlDataReader dReader;
            SqlCommand cmd = new SqlCommand(procedure, con);
            cmd.CommandType = CommandType.StoredProcedure;
            con.Open();
            dReader = cmd.ExecuteReader(); // This is the last place my bullet check gets before it hop's out!
            if (dReader.HasRows == true)
            {
                while (dReader.Read())
                    namesCollection.Add(dReader["SystemUser"].ToString());
            }
            con.Close();
            dReader.Close();
}
catch(Exception e)
{
    // handle the exception better than me :)
    Console.WriteLine(e.Message);
}

Put a messagebox or a breakpoint on the console.WriteLine and see what's happen.
