New Post: How do I create a Contact Group?

Azurath — Mon, 11 Jul 2011 10:16:39 GMT

Hi,

I realised that there's similar structures with Contact.Net which have similar classes including ContactManager which has functions like GetContactCollection(). However Contact.Net has the function with an additional parameter to retrieve the contactType which is an enum also available within the C4F code.

Is there anyone that has done grouping with C4F? How can I create and retrieve a group and classify people to a group?

Thanks.

New Post: Bluetooth : RemoteService IsConnected() does not work correctly

orover — Fri, 28 Jan 2011 17:03:27 GMT

Hello. I have the following code:

            List<RemoteService> serviceList = bluetoothDeviceServicesManager1.DiscoverServicesByType(SelectedDevice, ServiceType.SerialPortProfile);
            RemoteService remoteService = null;

            try
            {
                remoteService = serviceList[0];
                if (remoteService.IsConnected())
                {
                    remoteService.Disconnect();
                    _stream = null;
                }
                _stream = remoteService.Connect();
            }
            catch (ServiceConnectionException servEx)
            {
            }

I get the remoteService.IsConnected() == false and exception

{"Unable to connect to service. Only one usage of each socket address (protocol/network address/port) is normally permitted C4F.DevKit.Bluetooth.ServiceAndDeviceDiscovery.BluetoothEndPoint"}

Why and how to do it correctly?

New Post: Windows freezes

Pammachio — Sun, 31 Jan 2010 15:03:53 GMT

I all,
I have a problem on my Windows Vista that began afetr the purchase of an external Hard Disk Freecom.
A few days afetr the purchase I disconnected it while it was writing and, since that moment, every time I connect and disconnect it, the PC go to freeze mode for 5 minutes.
The same thing happen even if the hard disk is disconnected: every time I start windows it go to freeze a little after the password, and every time I connect and disconnect a usb device.
I have looked for the solution everywhere, updated windows, unistalled and installed the hard disk from the device manager but I solved the problem only when I restored a recent backup.
Yesterday the Hard disk was writing a backup while Vista was installing the updates; at the end of the proceure windows restarted automatically and the problem began again!!!
The Pc go to freeze when it starts, every time I connect or disconnect the hard disk, an usb earphone that has always worked switch on but there is no audio and I don't know how many others usb devices will have problems.
Has anyone an idea to solve this problem before I throw out of the window Vista or the the hard disk?
Thank you

New Post: C4 is not downloading

sumbuddy — Sun, 02 Aug 2009 02:34:41 GMT

So I am not alone in being unable to download code, binaries, etc from Codeplex. This is not my first experience with it either. If Microsoft is smart they'll stop handing downloads off to this remarkably secretive bunch. Tell me, is the formula 1 put out the betas,RC,RTM versions of some new technology and the minute you find out it throws exceptions, freezes up, or crashes your machine to put it on CODEPLEX which we all know is capable of putting up simple download links that work. Then CODEPLEX then sees all the backdraft of the same problems Micrososft kept getting reports on, so the just make it appear downloadable and by the time the last of us gives up they came up with another way to do it and use the success to Launch Windows8 next July? Yeah I know that's OTW suspicion. But these are elementary pages that could be written with about an hours worth of instruction to a beginner. I wish this could help you get the downloads to download. At least I'm not sitting on my lilypad waiting for someone else to croak first. Please fix it or start telling us which projects are stillborn if you are going to post it.

Deathwing00 — Mon, 27 Apr 2009 20:06:18 GMT

Hello,

Why isn't this great Bluetooth library not maintained anymore? It's the only one that works with Windows Vista 64 bit!!! Even more, why isn't Bluetooth added in the main .NET Framework standard APIs???
