i don't know what i am doing wrong here is my code so far but the device doesn't seem to connect .. it just waits and waits and then trouws an exception.. do i have to do something before i can connect.. or what? i am using widcomm stack.. an everything else is runnig right.. except what i sayd above :)

                BluetoothRadio[ radios = BluetoothRadio.AllRadios;
               BluetoothRadio BTRADIO = BluetoothRadio.PrimaryRadio;
               string adress = BTRADIO.LocalAddress.ToString();

               string name = BTRADIO.Name;



               if (BTRADIO.Mode == RadioMode.PowerOff)
                   BTRADIO.Mode = RadioMode.Connectable;


               BluetoothClient test = new BluetoothClient();
               BluetoothDeviceInfo[ devices = test.DiscoverDevices();

               BluetoothListener BTLISTNER;


               //Console.WriteLine("There were " + arr.Length + " devices found:");

               if (BTRADIO.Mode == RadioMode.PowerOff)
                   BTRADIO.Mode = RadioMode.Connectable;


               WriteToTextBox1( "There were " + devices.Length + " devices found:" + '\t' );
               WriteToTextBox1("\t" + "tässä");
               int port = 1;
               foreach (BluetoothDeviceInfo b in devices)
               {


                   WriteToTextBox1("");
                   WriteToTextBox1(("").PadRight(24, '-'));
                   WriteToTextBox1("\t" + b.DeviceName);
                   WriteToTextBox1("\t" + b.ClassOfDevice);
                   WriteToTextBox1("\t" + b.Connected);
                   WriteToTextBox1("\t" + b.DeviceAddress);

                   //WriteToTextBox1("\t" + b.InstalledServices);
                   WriteToTextBox1("\t" + b.LastSeen);
                   WriteToTextBox1("\t" + b.LastUsed);

                   WriteToTextBox1(("").PadRight(24, '-'));

               BluetoothAddress ADDRESS = b.DeviceAddress;
                WriteToTextBox1("\t" + ADDRESS.Sap );
                WriteToTextBox1("\t" + ADDRESS.Nap );

               if ( b.DeviceName == "RemoteDevice" )
                {

                    BluetoothEndPoint ep = new BluetoothEndPoint( ADDRESS, BluetoothService.SerialPort );


                   if (test.Connected)
                   {

                       test.Close();

                   }

                   //Try to connect
                   try
                   {

                       test.Connect( ep);    //this doesnt work.. it doesnet connect and gives exception thaht widcomm doesn't support sockets..
                   }
                   catch (Exception)
                   {
                       WriteToTextBox1("ERROR in openig connection");//setLabel("No connect() possible: " + e);

                   }

Yikes I didn't have all this problems! What platform are you running on? XP or Vista? I haven't tested on Vista.

Are you using dependency walker to know these missing DLLs, can you show me a screenshot of it. I suspect these DLLs are not actually necessary -- likely they're not statically linked but instead delay-loaded, see e.g. http://social.msdn.microsoft.com/Forums/en-US/vsx/thread/6bb7dcaf-6385-4d24-b2c3-ce7e3547e68b DWMAPI.dll is a Vista-only DLL, did you copy it to XP? it is delay-loaded and is not loaded unless the code find that the platform is Vista. So it should not be needed/used on XP.

I am not at my PC at the moment so maybe you can try this. Create a very simple console application with VC++. Have it link to 32feetWidcomm.dll. Run it and see if it reports any dependency errors... :-,)

If you haven't got the btwapi.dll I can email you it.

If you're using the 32feetWidcomm.dll from codeplex then that's the Debug version and you need some other MS CRT libraries -- the debug equivalents. You could use the 32feetWidcomm.dll contained in the release (http://32feet.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=28849) it's a release build.

hello.

same problem is still on.. i have visual studio 2008 ont his computer so i had version 9 runtime librarie. I am missing MSVCR80D.DLL and BTWAPI.DLL.. so i am trying to install those MS version 8 runtime libraries.. but i have no luck in this. still not working.

Re: Problems with in the hand with widcomm

alanjmcf — Thu, 18 Jun 2009 10:26:30 GMT

That probably means that you need to install the Microsoft’s “version 8” runtime libraries. See "32feet and Widcomm-Broadcom.doc" for more info. As suggested there "To check if any dependencies are missing load the 32feetWidcomm.dll into the depends.exe utility". Or just install that library from Microsoft and see if that solves it. :-)
