Connecting to a Scanner

C#

Hi Guys,

I have a problem and asking for your help.
I have this API that connects to a Scanner, the Scanner is connected to a machine via a usb cable. It doesn't appear on as USB but as a COM port.

Now i want to talk to the scanner so that it dumps the data that is stored in it in a location on the machine.

Please can you help me.

Below is the code for the API.

/// <summary>
       /// Filter out custom messages
       /// </summary>
       /// <param name="m">Message value - cannot be changed</param>
       /// <returns>false = messages will be prosessed by the appliction, true = message will be deleted and
       /// not processed</returns>
       public bool PreFilterMessage(ref Message m)
       {
           bool res = false;//by default allow the message to be dispatched to the rest of the app
           try
           {
               if (m.Msg == fCustomMSGHandle && m.Msg <= fCustomMSGHandle)
               {
                   if (fCallback!=null)
                   {
                       fCallback(m.Msg, (int)m.WParam, (int)m.LParam, (int)m.HWnd.ToInt32());
                   }
                   res = true;
               }
           }
           catch (Exception)
           {
               res = false;
           }
           return res;
       }

this is where i get suck. :-) Please can you assist?

Kind Regards,
Ndeza,
