I am trying to create a class library accessible to in SQL server as a
COM. I am using the Wininet.dll and can get it to build successfully. I
then run tlbexp and create the type library and when I attempt to
register the dll with regasm.exe I get the following error:

RegAsm : warning RA0000 : No types were registered

This is my code:

using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
using System.Reflection;
using System.IO;

namespace BDS_FTP
{
   public class FTP
   {
       public FTP()
       {
           //COM requires an empty constructor
       }

       //DECLARATIONS

        [DllImport("wininet.dll")]
        public static extern long InternetOpen( string strAppName,
                                               long ulAccessType,
                                               string strProxy,
                                               string strProxyBypass,
                                               long ulFlags);

        [DllImport("wininet.dll")]
        public static extern long InternetConnect(long ulSession,
                                                   string strServer,
                                                   int ulPort,
                                                   string strUser,
                                                   string strPassword,

                                                   long ulService,
                                                   long ulFlags,
                                                   long ulContext);

      [DllImport("wininet.dll")]
       public static extern bool InternetGetConnectedState(ref uint
ulFlags, uint ulReserved);

       [DllImport("wininet.dll")]
       public static extern bool FtpSetCurrentDirectory(IntPtr
ulSession, string strPath);

       [DllImport("wininet.dll")]
       public static extern bool FtpGetFile(IntPtr ulSession, string
strRemoteFile, string strLocalFile, bool bolFailIfExist, ulong ulFlags,
ulong ulInetFals, ulong ulContext);

   }
   
}

Any advice or help would be greatly appreiciated!
Thanks!
