W540 - Toggle output/input from 3.5mm plug to speakers/microphone.
>> W540 - Swissvoice, iPhone earbuds/microphone toggle to/from built in audio hardware and Fn Key toggle ,,
I still can't figure out how to program the Fn Keys.
Scenario: I use a Swissvoice handset at home, an iPhone earbud/microphone combo on the road, and when on a business link with more than one person in front of the W540, I switch to the built in speaker/microphone.
Right now to switch from the mini plug to the hardware speaker/microphone, it's several steps to achieve the objective.
With the multitune of Fn keys, can one be programed to quickly switch thew output/input from the micro 3.5mm connector to the built in hardware?

I can hear the noise through all kinds of headphones and the internal speakers, but the power running through those is usually so low that the pop is negligible.
My speakers are set to 0 dB, which is massively loud (the volume control kind of clicks in place at 0 dB, so I keep it there), so I keep the volume down digitally on my MBA. But this means that any "uncontrolled" sound output will be pretty loud, such as if I unplug the jack and touch it.

How to get audio input through 3.5mm on MacBook Air
I am trying to use the 3.5mm jack on the MacBook Air as an input jack. I am running several Mic's to a sound board, and then using it's output to get the audio to my system. The problem is, when I plug the cable into the jack, it thinks it is speakers. Does anybody have a solution? I cannot find any way to manually adjust this from output to input. Also, using USB is not an otion, becuase it is coming from a sound board, not jus one mic.
I am using a mid-2011 MBA with Lion 10.7.5
Thanks!!!Maybe you can help me now?
I have a iPhone 1/8 inch microphone adapter - 3.5mm 4 conductor TRRS Male to 3.5mm Microphone Input Jack from here. that allows me to plug my lapel mic directly into my iphone and record, it is great.
I was hoping I could also use it on my MBPRetina to accomplish the same purpose. Do you know if that is possible? I tried and tested it recording a video in iMovie, and didn't notice any change.
I went to the Sound Input Preferences, and do not notice the mic input changing when I plug it in or remove it. In other words, it always says "internal mic."
My lapel mic is battery operated, with a fresh battery, and it was turned on.
What am I doing incorrectly? Any help would be wonderfully appreciated! -
No output sound from output port/analog audio: Need help
hello, I want to connect my analog audio equipment to my iMac. I have done this in the past with my old G3. I have connected the RCA cables to a 3.5 mm jack and put it into the audio input port, which was what worked on the G3. When I open the sound page for input & output, on Output I can see the volume bar thing moving in relation to the sounds from mic, turntable, etc: all the analog audio things. However, there is no actual output of sound through the iMac;s speakers or a headphone. The output page is pretty simple so I am real sure I have all the rigt things checked, unchecked etc. Any ideas? Thanks.
I had what sounds like a similar problem to jazzzrat. i had my macbook setup to a stereo and it worked for over a year. suddenly no sound came out of the stereo. in my case, it definitely was a software setup thing.
plug in your stereo jack into the audio out port. then go to system preferences-->sound-->output. on there you should see, under "device for sound output": Name=Headphones, port=built-in output. (if you see name=built in speakers, you plugged in the wrong plug). Now go down to the bottom of the window and UNcheck the "mute" box, and make sure the volume slider is midway or more.
For some reason, mac allows you to mute the "headphones" and "built in speakers" selectively. we have no idea how that box got checked, that remains a complete mystery. but when we eventually found -- and unchecked -- the box, our stereo output came back just fine.
i hope this works for you. good luck and have a good new year. -
Is there an easy way to switch iPhone microphone input from headphones to Bluetooth and back?
When driving I plug my iPhone into the car stereo AUX jack with a cable to listen to music. To receive or make phone calls, or to use Siri, I use a Bluetooth (Jawbone) headset.
If I'm playing music out the headphone jack and then answer a call, when the call ends the music starts playing again through the Bluetooth headset, so I have to switch it back to headphones. Theoretically no big deal, since there's the little airplay icon at bottom right in most music apps. Still, I really wish it would revert to playing through the headphone jacks and I didn't have to do anything. Is that possible?
But it gets more annoying. Let's say I decide to use Siri and want to use the bluetooth. This is fine IF I plugged the headphones in before connecting Bluetooth, but for some reason it often seems to happen that it defaults to the headphone jack, especially if I've been messing with it a bit -- say I was listening to music, then received a call, then hung up, so now music plays through Bluetooth, so I hit the icon to switch music back to headphones, though sometimes this doesn't work and I have to unplug and replug in the headphones. But now usually if I want to use Siri, and I hold down the iPhone home button, or even if I hold down the jawbone button, it will often take input still from headphones.
I can't go into all the variations of this that happen, but almost every car ride there's a pain about this -- someone calls but even though I answer through my headset, the input is still from the headphone jack, and i have to scramble to get the call going through Bluetooth again. Or I have to unplug then replug the headphones after Siri use. None of this even covers something other, like dictating text or making a voice memo, something else that need simply but DOESN'T have an AirPlay-style button on bottom right like the music apps do. Really a pain.
Really wish there were some easy switch to toggle the input.
And again, really wish the music would just go back to playing where to was playing from (headphones) instead of making me switch it either via a button or through unplugging/replugging headphones.
Any solution to this?
Thanks.Sometimes you turn off your Bluetooth and then back on and it doesn't reconnect with your phone unless you go into the menu. Either way doesn't help much if someone calls you while you're driving and you realize your iPhone is stuck on headphone input.

I understand that the Envy 23 has a single pin jack for input/output (headphones).
However, I have never been able to get the jack to work as an analog input (from a record turntable & mixer to digitize vinyl). It worked fine on my old HP desktop (with the designated separate jacks). No input signal at all...
I've tried different kinds of 3.5mm jack (2 ring, 3 ring), different digitizing programs, every configuration I can think of in the Windows audio device controls...nothing.
any ideas? I'm at my wit's end!Hi,
Firstly have you tried somting similar to the following adapter ?
Secondly: have you tried a microphone with the above adapter ?
Regards.

I am having trouble sending an audio signal from my computer (mac pro early 2009) to my TV. Is there some interface or adapter that allows /enables the audio input from my computer to be sent to the TV (R,L signal?) any suggestions
just the audio, eh?. If you were using DVI or DisplayPort that might be different, but for audio alone, it shouldn't be that hard. Just grab a 3.5 mm stereo plug to 2 rca cables adapter. Plug the smaller end into the back of your Mac Pro (or the Front), where you see either the headphone or speaker icon). Alt-click on the speaker icon at the top of your screen to show all audio inputs and outputs. Make sure it's set to Line Out. Plug the red and white end into the audio in jacks on the back of your tv and set it to the correct input. I don't know if your tv will allow just the audio to play. Usually one has to connect up something else, but hopefully I'm wrong. If you were using DVI, or DisplayPort, you'd need an active DVI--HDMI adapter or a DisplayPort to HDMI adapter, but
I don't know for sure

Is it possible to input itunes into DVI/HDCP input from imac with Apple mini display portS?
Is it possible to input itunes into DVI/HDCP input from imac with Apple mini display port? Or is there another way?
The problem with itunes is needing a computer running it. or continuous internet connection.
A Time Capsule is AC mains powered.. no battery. Although you can certainly buy an older Gen4 TC and modify it ...
https://sites.google.com/site/lapastenague/time-capsule-power-supply-repair-kits
I have run my TC on a 12V SLA battery.. which would neatly meet that part of the functionality you want. But it is heavy and not really the rugged sort of device I think you want.
But I would look at other media players and other ways of storing movies than iTunes.. if you want to carry the whole lot around with you .. A bunch of SD cards even you could plug into the ipad??
External storage for iPad?
A small cheap PC/Mac laptop with a 1TB hard disk in it.. and 11" or 13" screen.. can often be a much better solution than lugging around multiple items so you can fit Apple devices into your life. -
Getting input from textbox as "console"
Hi all. I am learning C# and have a Windows forms project that I am working on to learn various techniques. Basically it has a text box that I use to mimic a console. The user enters a command followed by the Enter key and the program reads that in and interprets
it. I also have some rudimentary "batch" commands, such as IF/THEN, INPUT and PRINT.
The application has two main components: The form and a class. The form takes care of interpreting the commands that the user enters and the class implements the three batch commands (more to follow in the near future). The issue that I am having is that
sometimes (maybe 2%) the INPUT functionality does not work. When I enter a string and press Enter an empty string is returned. I have tried to debug this as much as I can, but it is difficult since this problem only happens once in a while.
I have extracted the INPUT functionality and duplicated it in a simple app which I present here. The test app contains one button called btnConRead and a multi line text box called txtConsole. Clicking the button "forces" the app into "run"
mode where the batch commands are interpreted. For this example I run the code that runs when an INPUT command is being processed. The app prompts with "OK" and waits for the user to type something in. When the user presses the Enter key the entered
string is echoed on the console. The form module contains this code:
string sKBBuf = ""; //App wide KB buffer when form Key preview is enabled.
bool bEnter;
private delegate void DisplayMsgDelegate(string sMsg);
private void cEventPrint(object sender, PrintDataEventArgs e)
Display(txtConsole, e.sPrintLine);
private void cEventRead(object sender, ReadDataEventArgs e)
//Event that reads text from the console and returns it.
//This event requires input from the user. It traps the program here until the user
//presses Enter.
//Clear the KB buffer.
sKBBuf = "";
//Loop incessantly until user presses Enter key or Stop key (s).
do
//Braindead.
} while (!bEnter);
if (bEnter)
//User pressed the Enter key, return the KB buffer.
e.sReadLine = sKBBuf;
//Empty buffer.
sKBBuf = "";
//Reset Enter key flag.
bEnter = false;
//Push CRLF to console.
Display(txtConsole, Environment.NewLine);
private void DisplayMsg(string sMsg)
txtConsole.AppendText(sMsg);
private void Display(TextBox txtOutput, string sMsg, bool bToCon = true)
//Check output to console flag.
if (bToCon)
if (txtOutput.InvokeRequired)
txtOutput.Invoke(new DisplayMsgDelegate(DisplayMsg), sMsg);
else
txtOutput.AppendText(sMsg);
private void GetConInput()
clsExample cEx = new clsExample();
cEx.ReadData += cEventRead;
cEx.PrintData += cEventPrint;
System.Threading.Thread runThread = new System.Threading.Thread(() =>
cEx.Process();
this.KeyPreview = false;
this.KeyPreview = true;
runThread.Start();
private void btnReadCon_Click(object sender, EventArgs e)
//Prep stuff
sKBBuf = "";
txtConsole.Focus();
Display(txtConsole, "OK" + Environment.NewLine);
//Read console textbox
GetConInput();
private void Form1_KeyPress(object sender, KeyPressEventArgs e)
bEnter = e.KeyChar == 13;
//Save to buffer. At this time I am not distinguishing from letter or digits.
//But I do need to check for a BS.
if (e.KeyChar == 8)
//Yeah, BS, remove the last char, if any.
if (sKBBuf.Length > 0)
sKBBuf = sKBBuf.Substring(0, sKBBuf.Length - 1);
else
sKBBuf += e.KeyChar;
The class is called clsExample and contains the following code:
//Event raised when data needs to be printed to console.
public event EventHandler<PrintDataEventArgs> PrintData;
//Event raised when data needs to be read from console.
public event EventHandler<ReadDataEventArgs> ReadData;
protected virtual void OnReadData(ReadDataEventArgs e)
EventHandler<ReadDataEventArgs> handler = ReadData;
if (handler != null)
handler(this, e);
protected virtual void OnPrintData(PrintDataEventArgs e)
EventHandler<PrintDataEventArgs> handler = PrintData;
if (handler != null)
handler(this, e);
public void Process()
ReadDataEventArgs argsRead = new ReadDataEventArgs();
PrintDataEventArgs args = new PrintDataEventArgs();
string sMsg = "";
//Get input from user.
OnReadData(argsRead);
if (argsRead.sReadLine.Length > 0)
//I have something
sMsg = argsRead.sReadLine;
else
//No data
sMsg = "*";
args.sPrintLine = sMsg + Environment.NewLine;
OnPrintData(args);
Plus two more support classes for the Print and Read events:
public class PrintDataEventArgs : EventArgs
public string sPrintLine { get; set; }
public class ReadDataEventArgs : EventArgs
public string sReadLine { get; set; }
All the above was necessary so that the Process procedure running in a different thread could interact with the UI elements in the main form. The above mostly works, but I wonder if I am doing it the right way. I don't particularly like the use of
global flags, such as bEnter or having empty loops to just "kill" time, such as the one found in the cEventRead procedure.
In the cEventRead procedure I had the if() block immediately following the empty loop inside
the loop and moved it out of there to see if this made any difference, but apparently it did not. Can anyone provide any feedback or suggestions of what I could change to make it work 100% of the time? I appreciate your time and effort. Thank you, Saga
You can't take the sky from meHi all. I am learning C# and have a Windows forms project that I am working on to learn various techniques. Basically it has a text box that I use to mimic a console. The user enters a command followed by the Enter key and the program reads that in and interprets

Hi Saga,
Please don't use such kind of loop in your code, if you want to monitor the user input, just use the KeyPress event provided by the TextBox control.
Control.KeyPress
Event
If you just want to execute some standard commands, I recommend that you use
Process to start cmd.exe to execute the command, for example:
void ExecuteCommand(string command)
int exitCode;
ProcessStartInfo processInfo;
Process process;
processInfo = new ProcessStartInfo("cmd.exe", "/c " + command);
processInfo.CreateNoWindow = true;
processInfo.UseShellExecute = false;
// *** Redirect the output ***
processInfo.RedirectStandardError = true;
processInfo.RedirectStandardOutput = true;
process = Process.Start(processInfo);
process.WaitForExit();
// *** Read the streams ***
string output = process.StandardOutput.ReadToEnd();
string error = process.StandardError.ReadToEnd();
exitCode = process.ExitCode;
Console.WriteLine("output>>" + (String.IsNullOrEmpty(output) ? "(none)" : output));
Console.WriteLine("error>>" + (String.IsNullOrEmpty(error) ? "(none)" : error));
Console.WriteLine("ExitCode: " + exitCode.ToString(), "ExecuteCommand");
process.Close();
If it's powershell script, you can also use the existing library to execute it, check this blogpost:

How can i create a dynamic structure based on my input from a select-option
Hello,
This is to develop a custom report in FI for G/L Balance based on company code.
I have an input select-option for Company code.
Based on the range of company code my output layout should be modified.
I am not very much sure to create a dynamic internal based on the input from a select-option.
Can any one please let me know how can i do this.
I would appreciate for anyone who turns up quickly.
Thank you,

How to Get Input from Command Prompt?
How can i get input from command prompt like
C:\
or linux ?
(Here's what I use now)
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
String line;
Whlie((line=in.readLine())!= null)
{ System.out.prinln( line) ; }
IS THERE A BETTER WAY?The main method within a java class accepts command line input through a String array.
In this example args is the String array. You can access the parameters as args[0] for the first parameter, args[1] for the second parameter, etc....
The usage for the example below would be :
c:\EDIFormat file1 file2
Where args[0] would equal file1 and args[1] would equal file2.
public class EDIFormat {
public static void main(String[] args) {
if (args.length < 0) {
System.out.println("No Parameters supplied. Exiting....");
// open input and output files
EDIFiles(args[0], args[1]);
Hope that helps! -
Required Attribute style XML input from BPEL
Hi all,
We are integrating JDE 811 with BPEL using ORACLE SOA Suite 10133.
As per the documentation given http://download-west.oracle.com/docs/cd/B31017_01/integrate.1013/b28996/bpel_pm.htm#CDEICHJB, we created the BPEL process to support transacation from BPEL to JDE 811. As given in the document we generated the WSDL in attribute style. For testing the BPEL Process, they have given the XML input in the document in the format of attribute style as given below :
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body xmlns:ns1="http://xmlns.oracle.com/GetYearDescription_SYNC">
<ns1:jdeRequest type="callmethod">
<callMethod name="GetYearDescription" runOnError="no">
<params>
<param name="mnCalendarYear">58</param>
</params><onError abort="yes"/>
</callMethod>
</ns1:jdeRequest>
</soap:Body>
</soap:Envelope>
and the output we received as
<GetYearDescription_SYNCProcessResponsehttp://xmlns.oracle.com/GetYearDescription_SYNCPSFTcallmethodDV811*ALL>
<callMethodGetYearDescriptionnourn:iwaysoftware:jde/services/JDEJAVA_CMFGBASE/B3000260/GetYearDescription>
<params>
<parammnCalendarYear>58</param>
<paramszYearDescription>2058</param>
</params>
</callMethod>
</GetYearDescription_SYNCProcessResponse>
But, if we use the current schema and give input using normal HTML form on the BPELConsole then the error comes like
WSIF JCA Execute of operation 'GetYearDescription' failed due to: Error in processing the input document.; nested exception is: javax.resource.ResourceException:
Error in processing the input document.</summary>
</part><part name="detail"><detail>javax.resource.ResourceException: Error in processing the input document.
that is why for outbound integration we need to give raw XML during runtime as input to the bpel process in bpel console manually. and that input looks like
Also in real time scenario, we are receiving the XML input from a third party software/Adapter that may be a flat file/.xml flat file/DB and we need to pass the similar data in BPEL to the JDE 811. Here we are not able to pass the data to JDE as the adapter accepts the input in attribute style XML.
If we are trying to enter that input through a flat .xml file then it returns no data, as nothing is passed to that process.
Any idea how we can process this without giving raw xml input manually during run time, means using normal HTML Form.
if it is not possible then please tell me what will be the required XML that we have to pass as input in that flat file.
Thanks,
AnindyaHi All,
SOAP based input is required for any BPEL process for testing in BPEL Console.
We have created a BPEL process which is successfully receiving data from 3rd party and it is not in a SOAP format.
That is why we are entering input manually (I have already described input in above post) while testing that BPEL process. and we can receive proper output (i have already specified what i am getting as output in my above post.)
But in real time scenario we cant give input manually.
how can we achieve SOAP based invocation during runtime??
I hope my question is clear to all.
please suggest me if anybody have any idea about this.

Problem with tokenized input from command line
I am trying to take an input from the command line, parse it to tokens and perform whatever operation is needed depending on the name of the token, on a binary tree of stacks for example, if i type 1 2 1 3 printLevelOrder, then the root of the tree should have 3, 2,1 in the stack, the left child should have 1 and the right child should be empty. and then a level order print of the tree should be performed.
however what is happening when i run this code is the numbers are being put into the right stacks of the tree, but any commands such as printLevelOrder or PrintPopRoot are entering the code that is for placing numbers onto the stack instead of executing that command and skipping past this piece of code.
so my question is, why is the if statement if (word =="printLevelOrder") not being executed when thats whats in the word ?
example input and output shown below code fragment.
try {
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
String line = "";
while (line != "***") {
System.out.print("> prompt ");
line = in.readLine();
StringTokenizer tokenizer = new StringTokenizer(line," ");
String word = new String();
while (tokenizer.hasMoreTokens()) {
word = tokenizer.nextToken();
boolean notCommand = true;
if (word =="printLevelOrder") {
theTree.printLevelOrder();
System.out.println("(word ==printLevelOrder)");
notCommand=false;
if (word == "printPopLevelOrder") {
theTree.printPopLevelOrder();
notCommand=false;
if (word == "printPopInorder") {
theTree.printPopInorder();
notCommand=false;
if (word == "printPopPreorder") {
theTree.printPopPreorder();

Press any key to continue . . .lol aww, shame that you forgot to do that. i had 10 / 10 for mine, and seing as the deadline is now well and trully over,
here is the entire source for anybody who was following the discussion or whatever and wanted to experiment.

/*TreeStack.java - reads command line input of values and assigns them to stacks in a binary tree and performs
operations on the ADT. valid inputs: <int>, printLevelOrder, printPopLevelOrder,
printPopInorder, printPopPreOrder, printPopRoot. Terminates on invalid input.

How do i get input from the user?
For example if i wanted to ask "Whats your favorite number" and then get the input from the user and assign it to a variable how would i go about doing that?
hi,
if you want to get input from your console your should work with io(input and output).The BufferedReader class, InputStreamReader class
you should import "java.io.BufferedReader" and "java.io.InputStreamReader" package, and do something like this:
BufferedReader input = new BufferedReader(new InputStreamReader(System.in));
String favoriteNumber;
System.out.println("Whats your favorite number ");
favoriteNumber = input.readLine();
System.out.println ("Your favorite Number Is " + favoriteNumber);
if its a gui you should import "javax.swing.JOptionPane" and do the following
String favoriteNumber = JOptionPane.showInputDialog(null, "Enter your favorite Number", "Favorite Number", JOptionPane.INFORMATION_MESSAGE);
