Hi, I was wondering how to use TAPI in C++ to communicate with my modem. How would I accomplish this? I'm not using Visual C++. I'm using dev-c++ 4.9.9.2.

What do you mean "how"?

How I would do it would be
- STW for tutorials and examples
- Read the manual pages
- Try some examples
- Do some design work on the system I want to implement
- Write some code, then test it.
And so on.

Same as any other software problem really. The "TAPI" and "C++" isn't special in that respect.

By "How", I mean I looked for like an hour finding only stuff about .Net, and was wondering what the code would be, what libraries I might have to get, and so on. Like I said before, I'm using Dev-C++ 4.9.9.2, so anything that could be compiled with that IDE would help me a lot.

C++ doesn't care whether your IDE is "Visual" or "Dev".
Again, if you've already found some C++ code, you're already like 95%+ of the way there.

How would you compile this in Dev?

using System;

      static void Main(string[] args)

         TTapi tapi = new TTapi();
         TCall call = null; TAddress modemAddr = null;

         tapi.Initialize();
         tapi.TE_CALLNOTIFICATION += delegate(object sender, TapiCallNotificationEventArgs e)  
         {
            Console.WriteLine("New call {0} detected from {1}", e.Call.ToString(), e.Event);
         };
         tapi.TE_CALLSTATE += delegate(object sender, TapiCallStateEventArgs e)
         {
            Console.WriteLine("{0}:{4} has changed state to {1} due to {2} - current={3}:{5}", 
                  e.Call, e.State, e.Cause, e.Call == call, e.Call.GetHashCode(), (call != null) ? call.GetHashCode() : 0);
            if (e.State == CALL_STATE.CS_INPROGRESS && e.Call == call)
            {
               Console.WriteLine("Dropping call");
               e.Call.Disconnect(DISCONNECT_CODE.DC_NORMAL);
            }
         };

         foreach (TAddress addr in tapi.Addresses)

            if (String.Compare(addr.ServiceProviderName, "unimdm.tsp", true) == 0 && 
               addr.QueryMediaType(TAPIMEDIATYPES.AUDIO))

         if (modemAddr != null)

            modemAddr.Monitor(TAPIMEDIATYPES.AUDIO);
            ConsoleKey ki = ConsoleKey.A;

            while (ki != ConsoleKey.Q)

                  Console.WriteLine("Set AutoDestroy to {0}", tapi.AutoDestroyCalls);
               }

                  {
                     Console.WriteLine("Existing call found: {0}:{1}", _call, _call.GetHashCode());
                     _call.Dispose(); // Go ahead and dump it
                  }
               }
               // Create a new call
               else
               {
                  call = modemAddr.CreateCall("5551213", LINEADDRESSTYPES.PhoneNumber, TAPIMEDIATYPES.DATAMODEM);
                  Console.WriteLine("Created new call {0}:{1}", call, call.GetHashCode());
                  try
                  {
                     // This will fail if existing call interface is still around (i.e. not disposed)
                     call.Connect(false);
                  }
                  catch (TapiException ex)
                  {
                     Console.WriteLine(ex.Message);
                  }
               }
               Console.WriteLine("Press a key to try another call.. Q to quit");
               ki = Console.ReadKey().Key;
            }
         }

         // This will destroy any outstanding interfaces
         tapi.Shutdown();

         // Call should be disposed here.. state will be CS_UNKNOWN 
         if (call != null)
            Console.WriteLine("{0} {1}", call, call.CallState);
      }
   }

OOOOOOOPSSSSSSSSSSS, I'm StUPID. No i didn't. I don't know why I put that........:$ :$ :$
I'm an idiot.......................
