Reading characters from the console, ONE AT A TIME
I'm writing a small Java program that will have a command line interface
(sort of a 'shell').
The thing is, that I want to recognize special keys being pressed by the
user. No matter what I tried (System.in.read(); for example), it gives the
characters one by one, all right, but only after the <ENTER> key is
pressed!!!
Is there a way to REALLY get the keys immediately when the user presses
them?
Thanks
u.s
If you're willing to have your own window, you can attach a KeyListener to a Component. I don't know how to do it in console mode.

How can I store the music I listen to on my iphone without streaming it from the cloud and using all my data on my phone plans? How do I dump it on my phone all at once in itunes rather than waiting for each song to download individually from the cloud?
What?? You asked how to get all your music on your phone at once rather than downloading it to your phone from iCloud.
Go to your purchased list in iTunes and download all your music to your iTunes library, as explained in the linked article. Then sync it all to your phone using iTunes you're done. The music will be stored locally on your phone and you won't have to download it again in the future. -
After installing the reportservice/database i cannot use the Configuration Manager Console 2012 anymore with my own AD account. (The accounts of my colleagues are stil working)
When i login i get the following message:
The user account running the Configuration Manager console has insufficient permissions to read information from the Configuration Manager site database. The account must belong to a security role in Configuration Manager. The account must also have
the Windows Server Distributed Component Object Model (DCOM) Remote Activation permission for the computer running the Configuration Manager site server and the SMS Provider.
I checked the following:
I am a administrative user in SCCM (Full Administrator)
I am a member of the administrator group on the server
Deleted HKEY_CURRENT_USER\Software\Microsoft\ConfigMgr10
I tried to start it on multiple workstations and deleted my roaming profile

Reading a String from the Console.
Hello,
I am new to Java... I have to write a program which will read a long value from the console. Can somebody help me in this? or can i read it as a string and then convert to Long ? I prefer the second one as I am planning to convert this code to read a SOAP message... Can somebody help me or pint me to the right direction?
Thanks,Reading it as a string and then parsing it (Long.parseLong(...)) is the way to do this.
As far as converting to SOAP - slow down. If you're just getting started with java, you're going to be biting off a lot trying to tackle SOAP -
Hii
I'm trying for 2 days to read characters from console on the fly, but it didn't work.
I want to read each char that user press on line and without waiting for the Enter button. It's like an keyboard event but there is no GUI.
I will appreciate any help.
Thanks.I don't understund what you really want to do.it is possible mesure the time between each char type using the last code :
char charPressed='\0';
String line="";
while(charPressed != '\n')
try
// start time
charPressed =(char) System.in.read();
line += charPressed;
// end time
// want to get out
if(...) break;
catch(IOException ioex) {ioex.printStackTrace();}
Sorry, but your code doesn't measure the time between each char type.
The function read waits for the "enter" key, and just after pressing enter your code will start to read all the chars you typed before "enter", so it won't do it.
Read function will not help in this subject. -
Error reading data from the MS Dos Console.
Hi,
We have a legacy application which is launched via a 3rd-party Telnet Server - the app acts as a remote shell for an RF device. The system has been functioning for many years but now we have migrated to Server 2012 the system no longer launches.
The RF device successfully connects to the telnet server, logs-in with embedded credentails but drops the connection when the shell application is launched.
The server has the following Application error
Error reading data from the MS Dos Console.
The pipe has been ended. 109 (0x6d)
The application can successfully be launched locally outside of the shell on the server. The error is reproducable across RF devices and desktop telnet connections.
The firewalls are off.
Are there some additional protections in Server 2012 which would cause the pipe-based link to be stopped when launching the exe? Am I missing something? The 3rd-party telnet server is certified for Server 2012.
Thnak youI'd ask in the
Windows Server General Forum, or ask the third party vendor.

Hi Everybody,
i'm playing a little bit with Windows Azure and I'm blocked with a really simple issue (or maybe not).
I've created a Cloud Service containing one simple Worker Role. I've configured an EndPoint in the WorkerRole configuration, which allows Input connections via tcp on port 10100.
Here the ServiceDefinition.csdef file content:
<?xml version="1.0" encoding="utf-8"?>
<ServiceDefinition name="EmacCloudService" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceDefinition" schemaVersion="2014-01.2.3">
<WorkerRole name="TcpListenerWorkerRole" vmsize="Small">
<Imports>
<Import moduleName="Diagnostics" />
<Import moduleName="RemoteAccess" />
<Import moduleName="RemoteForwarder" />
</Imports>
<Endpoints>
<InputEndpoint name="Endpoint1" protocol="tcp" port="10100" />
</Endpoints>
</WorkerRole>
</ServiceDefinition>
This WorkerRole is just creating a TcpListener object listening to the configured port (using the RoleEnvironment instance) and waits for an incoming connection. It receives a message and returns a hardcoded message (see code snippet below).
namespace TcpListenerWorkerRole
using System;
using System.Net;
using Microsoft.WindowsAzure.ServiceRuntime;
using System.Net.Sockets;
using System.Text;
using Roche.Emac.Infrastructure;
using System.IO;
using System.Threading.Tasks;
using Microsoft.WindowsAzure.Diagnostics;
using System.Linq;
public class WorkerRole : RoleEntryPoint
public override void Run()
// This is a sample worker implementation. Replace with your logic.
LoggingProvider.Logger.Info("TcpListenerWorkerRole entry point called");
TcpListener listener = null;
try
listener = new TcpListener(RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint1"].IPEndpoint);
listener.ExclusiveAddressUse = false;
listener.Start();
LoggingProvider.Logger.Info(string.Format("TcpListener started at '{0}:{1}'", RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint1"].IPEndpoint.Address, RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint1"].IPEndpoint.Port));
catch (SocketException ex)
LoggingProvider.Logger.Exception("Unexpected exception while creating the TcpListener", ex);
return;
while (true)
Task.Run(async () =>
TcpClient client = await listener.AcceptTcpClientAsync();
LoggingProvider.Logger.Info(string.Format("Client connected. Address='{0}'", client.Client.RemoteEndPoint.ToString()));
NetworkStream networkStream = client.GetStream();
StreamReader reader = new StreamReader(networkStream);
StreamWriter writer = new StreamWriter(networkStream);
writer.AutoFlush = true;
string input = string.Empty;
while (true)
try
char[] receivedChars = new char[client.ReceiveBufferSize];
LoggingProvider.Logger.Info("Buffer size: " + client.ReceiveBufferSize);
int readedChars = reader.Read(receivedChars, 0, client.ReceiveBufferSize);
char[] validChars = new char[readedChars];
Array.ConstrainedCopy(receivedChars, 0, validChars, 0, readedChars);
input = new string(validChars);
LoggingProvider.Logger.Info("This is what the host sent to you: " + input+". Readed chars=" + readedChars);
try
string orderResultFormat = Encoding.ASCII.GetString(Encoding.ASCII.GetBytes("\xB")) + @"MSH|^~\&|Instrument|Laboratory|LIS|LIS Facility|20120427123212+0100||ORL^O34^ORL_O34| 11|P|2.5.1||||||UNICODE UTF-8|||LAB-28^IHE" + Environment.NewLine + "MSA|AA|10" + Environment.NewLine + @"PID|||patientId||""""||19700101|M" + Environment.NewLine + "SPM|1|sampleId&ROCHE||ORH^^HL70487|||||||P^^HL70369" + Environment.NewLine + "SAC|||sampleId" + Environment.NewLine + "ORC|OK|orderId|||SC||||20120427123212" + Encoding.ASCII.GetString(Encoding.ASCII.GetBytes("\x1c\x0d"));
writer.Write(orderResultFormat);
catch (Exception e)
LoggingProvider.Logger.Exception("Unexpected exception while writting the response", e);
client.Close();
break;
catch (Exception ex)
LoggingProvider.Logger.Exception("Unexpected exception while Reading the request", ex);
client.Close();
break;
}).Wait();
public override bool OnStart()
// Set the maximum number of concurrent connections
ServicePointManager.DefaultConnectionLimit = 12;
DiagnosticMonitor.Start("Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString");
RoleEnvironment.Changing += RoleEnvironment_Changing;
return base.OnStart();
private void RoleEnvironment_Changing(object sender, RoleEnvironmentChangingEventArgs e)
// If a configuration setting is changing
LoggingProvider.Logger.Info("RoleEnvironment is changing....");
if (e.Changes.Any(change => change is RoleEnvironmentConfigurationSettingChange))
// Set e.Cancel to true to restart this role instance
e.Cancel = true;
As you can see, nothing special is being done. I've used the RoleEnvironment.CurrentRoleInstance.InstanceEndpoints to retrieve the current IPEndpoint.
Running the Cloud Service in the Windows Azure Compute Emulator everything works fine, but when I deploy it in Azure, then I receive the following Exception:
2014-08-06 14:55:23,816 [Role Start Thread] INFO EMAC Log - TcpListenerWorkerRole entry point called

I've already tried to configure an internal port in the ServiceDefinition.csdef file, but I get the same exception there.
As you can see, the client can connect to the service (the log shows the message: Client connected with the address) but when it tries to read the bytes from the stream, it throws the exception.
For me it seems like Azure is preventing the retrieval of the message. I've tried to disable the Firewall in the VM in Azure and the same continues happening.
I'm using Windows Azure SDK 2.3
Any help will be very very welcome!
Thanks in advance!

En caso de que la respuesta te sirva, porfavor, márcala como válida

Blog: http://jimenezroda.wordpress.comhi Javier,
I changed your code like this:
private AutoResetEvent connectionWaitHandle = new AutoResetEvent(false);
public override void Run()
TcpListener listener = null;
try
listener = new TcpListener(
RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint"].IPEndpoint);
listener.ExclusiveAddressUse = false;
listener.Start();
catch (SocketException se)
return;
while (true)
IAsyncResult result = listener.BeginAcceptTcpClient(HandleAsyncConnection, listener);
connectionWaitHandle.WaitOne();
The HandleAsync method is your "While (true)" code:
private void HandleAsyncConnection(IAsyncResult result)
TcpListener listener = (TcpListener)result.AsyncState;
TcpClient client = listener.EndAcceptTcpClient(result);
connectionWaitHandle.Set();
NetworkStream netStream = client.GetStream();
StreamReader reader = new StreamReader(netStream);
StreamWriter writer = new StreamWriter(netStream);
writer.AutoFlush = true;
string input = string.Empty;
try
char[] receivedChars = new char[client.ReceiveBufferSize];
// LoggingProvider.Logger.Info("Buffer size: " + client.ReceiveBufferSize);
int readedChars = reader.Read(receivedChars, 0, client.ReceiveBufferSize);
char[] validChars = new char[readedChars];
Array.ConstrainedCopy(receivedChars, 0, validChars, 0, readedChars);
input = new string(validChars);
// LoggingProvider.Logger.Info("This is what the host sent to you: " + input + ". Readed chars=" + readedChars);
try
string orderResultFormat = Encoding.ASCII.GetString(Encoding.ASCII.GetBytes("\xB")) + @"MSH|^~\&|Instrument|Laboratory|LIS|LIS Facility|20120427123212+0100||ORL^O34^ORL_O34| 11|P|2.5.1||||||UNICODE UTF-8|||LAB-28^IHE" + Environment.NewLine + "MSA|AA|10" + Environment.NewLine + @"PID|||patientId||""""||19700101|M" + Environment.NewLine + "SPM|1|sampleId&ROCHE||ORH^^HL70487|||||||P^^HL70369" + Environment.NewLine + "SAC|||sampleId" + Environment.NewLine + "ORC|OK|orderId|||SC||||20120427123212" + Encoding.ASCII.GetString(Encoding.ASCII.GetBytes("\x1c\x0d"));
writer.Write(orderResultFormat);
catch (Exception e)
// LoggingProvider.Logger.Exception("Unexpected exception while writting the response", e);
client.Close();
catch (Exception ex)
//LoggingProvider.Logger.Exception("Unexpected exception while Reading the request", ex);
client.Close();
Please try it. For this error message, I suggest you could refer to this thread (http://stackoverflow.com/questions/6173763/using-windows-azure-to-use-as-a-tcp-server

A week or so ago, the screen on the Macbook Pro I've had for 5 years went permanently black. The screen itself still works, but it's just all black. Went from flickering/flashing to black. I didn't have any kind of warranty on it or anything, and in addition to all of the other things about it that needed fixing, it seemed like it'd just be cheaper to get a new Macbook Pro.
My question is: How do I get all the stuff from the old laptop to the new laptop without having to use the old laptop's display? Is there a cable I can use to connect the two, and I can just access the old one from the new one?FireWire between the two (get appropriate 800-800 or 400-800), Target Disk Mode on the old one, appears as an external disk on the new one. Drag everything over, or use Setup Assistant if first start of new one, or plain old Migration Assistant. You really don't need a display to see a prancing FireWire icon, do you?

I am using iPhone 4 from the last one year and went dead and got it replaced by paying Rs.12500/- to Nyasa Sion Koliwada Mumbai Service Provider but now again after 38days the problem has started, what do i do? Is this is the quality & service we boost? On visiting the store we get only one reply you may write to Apple directely. we have the similar kind of problem with iPad which is being used by my wife Mr.Neelam Vij and paid Rs.16000/- to get it replaced within a year & 6months use. so in totality we have paid Rs.28500/- + Rs. 3000/- diagnostic charges.
1. iPhone 4 , 32 GB Black with Sr. No. 88******A4T
2. iPad 2, 16GB White with Sr. No.DL*******KPH
Moreover, we have no information to contact whom. even the replace set has a warranty of only three month which further confirm that Apple itself is not confident wheather product will last after replacement for more then three month. Such kind of happening do not encourage anyone to recomend this product to anyone. Would appriciate a faster response to our problem if someone from Apple is going to read this email.
Thanks & Regards

- Try making a backup of the iPod by right clicking on the iPod under Devices in iTunes and selecting Backup.

The fact is the vast majority of Mountain Lion users will not be experiencing any major problems with the OS, or maybe with apps which are not compatible, but thats hardly Apple's fault if developers don't update their apps. -
I set up two identities, the default & one more. How to get mail from the second one?
I have two different e-mail addresses that I want to get mail from. So the main/default one worked just fine. So I went to options, account settings, identities and set up the second one. But this second one doesn't appear on the start page and still when I Get Mail, it only brings in the mail from the default one. So what do I do?
You do not place your second account in Identities.
You go to the Menu Bar and select '''File-New-Existing Mail Account''' and add it there.
No Menu Bar? Press the alt key.
If using the '''AppMenu button''', click that and select''' New Message-Existing Mail Account''' -

Hi I have trouble in using alternative characters from the glyphs panel in illustrator CS5.
I have recently installed the CS5 version of Adobe Creative Suite I have purchased long ago.
I have trouble using the alternative characters from the glyphs panel. The problem doesn't happen with a specific font but a few.
There are fonts that work fine and fonts that do not (either true or open type fonts)
I can see the characters alternatives in the glyphs panel but when clicking only the normal characters appear.
I have also tried to re-install the fonts but didn't fix the problem.
Reading from previous posts that other users had same problem they concluded that there has been a problem / bug with the CS5 version glyphs that needed to be fixed
Is this the case? What shall I do?Hi - I have found the update so problem solved !
