Re: Using JOptionPane for Input and Output

You're going to get in big trouble with things like this: "if (memtype = P)"
Remember that '=' is for assignment, '==' is for comparison. Furthermore, you shouldn't use '==' for comparing Strings; you should use the String's equals() method instead.

Thank you for your reply and for the tip on using the ==,
I have seen this used, but the language you used to explain this is still a little too technical for me and I am not too sure what you mean when you said: "you should use the String's equals() method instead. "
what would the format of this look like?

I have on;y one audio port can i use it for input and output at the same time?

i have the new macbook pro 13 in and i want to connect aguitar as input and output on an amp but i have only one audio port

You can't use the jack as an input and output simultaneously. The solution is to look for a USB or Firewire interface to get your guitar sound into the computer.

Different family class used for input and output when working with sockets

I have seen more or less everywhere the following code to open a socket and to receive input and send output through it:
Socket server = new Socket("anyservername", 25):
OutputStream out = server.getOutputStream();
PrintWriter pout = new PrintWriter (out, true);
pout.println("Hello");
InputStream in = server.getInputStream();
BufferedReader bin = new BufferedReader (new InputStreamReader(in));
String response = bin.readLine();
What I do not understand is:
Why the BufferedReader needs InputStreamReader as an argument whereas printwriter does not want the OutputStreamReader as an argument but it is OK with just the OutPutStream?
I would tend to believe that they should be more or less at the same level and use the same arguments?.
In that sense if I use BufferWriter instead of PrintWriter I bet It should be OK the following code?:
OutputStream out = server.getOutputStream();
BufferedWriter bout = new BufferedWriter (out);
String myOut = bout.writeLine();

1. Does it even compile?
2. While there is a fair amount of symmetry between reader and writer classes, don't assume it's exhaustive. Your best friend is the API:
[http://java.sun.com/javase/6/docs/api/]
3. Those were just examples. Code it the way you feel is best. I would specify charsets to make sure the encodings were platform independent. Networking and all that, don't you know...

How can I substitute characters in a string when the same characters are used in both input and output strings

Hi Numbers users,
I am trying to get Numbers 2.3 on OS X (10.9.1) to convert cells containing variable length strings composed of 6 letters, A, B, C, a, b, c into a second string containing the same 6 lettersusing the rule A to c, B to b, and C to a and vice versa, so for example cell A1 might contain string "AcBbCaaB" and I want Numbers to convert this into "cAbBaCCb" in cell B1. I have tried to use the SUBSTITUTE function (nested) without success so far as I end up with the letters either all uppercase or all lowercase. I understand why this is happening and maybe it isn't possible using SUBSTITUTE. Does anyone know if there is another function I can use to do this?
Thanks, Hugh.

you can use this method:
Add a new table, called "Translator", show as the bottom table:
Enter the data in columns B anc C as shown
cell A1 contains:
"=CODE(B1)"
select cell A1 and fill down
For the table on top enter your code in column A. The converted code will be in column B. Make sure there are enough columns (I went out to column AD):
B2=R2&S2&T2&U2&V2&W2&X2&Y2&Z2&AA2&AB2&AC2&AD2
C2=LEN(A2)
D2=MID($A2, COLUMN()−2, 1)
select D2, copy,
select cells D2 thru P2, paste
R2=IFERROR(VLOOKUP(CODE(D2), Translator::$A:$C, 3, 0), "")
select R2, copy,
select cells R2 thru AD2, paste
select B2 thru AD2 and fill down as needed
You can hide columns C thru AD

I need to find a more complicated example, specifically using arrays as inputs and outputs, to Code Interface Nodes.

I am a beginner in C programming and I cannot understand how to use the structures that LabVIEW creates for its arrays in C. Can anyone point me to a good example?

Check the following answer that I posted recently to a similar question.

Makin GUI for input and output

This is simple code for my Comp Science class at school, but I keep getting "Exception in thread "main" java.lang.NoClassDefFoundError: TrivialApplication"
and im tryin to figure out what i did heres my code:
import java.awt.*;
import java.awt.event.*;
import java.io.*;
import javax.swing.*;
public class Hypotenuse {
          double side1, side2, hypotenuse;
          String Fside1, Fside2;
     public Component components()
     final JTextArea text = new JTextArea();
     final JTextField InputText1 = new JTextField();
     final JTextField InputText2 = new JTextField();
     JButton button = new JButton(" OK ");
     button.setMnemonic(KeyEvent.VK_ENTER);
     button.addActionListener(new ActionListener(){
          public void actionPerformed(ActionEvent e)
               Fside1 = InputText1.getText();
               Fside2 = InputText2.getText();
     JPanel InOutField = new JPanel();
     InOutField.setBorder(BorderFactory.createEmptyBorder(30,30,30,30));
     InOutField.setLayout(new GridLayout(0, 1));
          InOutField.add(text);
          InOutField.add(InputText1);
          InOutField.add(InputText2);
          InOutField.add(button);
          return InOutField;
     public static void main(String Args[]) throws IOException
         try
          UIManager.setLookAndFeel(
               UIManager.getCrossPlatformLookAndFeelClassName());
         catch (Exception e)
          JFrame InOutFrame = new JFrame("Hypotenuse");
          Hypotenuse app = new Hypotenuse();
          Component contents = app.components();
          InOutFrame.getContentPane().add(contents, BorderLayout.CENTER);
          InOutFrame.addWindowListener(new WindowAdapter()
               { public void windowCloasing(WindowEvent e)
                    { System.exit(0);
          InOutFrame.pack();
          InOutFrame.setVisible(true);
}

It compiles OK for me, but it doesn't close properly, unless I change this
public void windowCloasing(WindowEvent e)
to this
public void windowClosing(WindowEvent e)

FINALLY INPUTTING and OUTPUTTING Annotations!

Ok, before everyone thinks that this is a very bad solution, I have to tell that I`m no programmer and my knowledge of PostgreSQL, Ruby or any other language is very poor.
With useful help from Jamie Hodge, fbm and Nicholas Stokes (mainly)
I could manage to write a command for inputting and outputting from Final Cut Server Annotations.
So lets go to the fun part:
INPUTTING:
1- Create a Response called "Annotations IN" (or whatever you want):
a - Reponse Action: "Run an external script or command"
b - Run Script > *Commnad Path: /Library/Application Support/Final Cut Server/Final Cut Server.bundle/Contents/Resources/sbin/fcsvr_run
Command Parameters: psql px pxdb -c "COPY pxtcmdvalue FROM '/FCSRV/annotation-in.txt' USING DELIMITERS '|';"
2 - Create a poll Watcher with name: "Watch for Annotations IN"
a - Enable: true
b - Monitor Address: Chooses a Device (create a new one or use a tmp one) and path to where you`ll going to put a txt file with the annotations.
c - Response List: Choose the Response you created "Annotations IN" in my case.
d - Event Type Filter: Created, Modified
e - Poll Watcher > Listing Frequency: 2 (or any number of seconds you feel like it).
Listing multiple: 2
Wildcard include Filter: *.txt (or any custom extensions you want)
3 - Create a txt file and use this as a template:
{ASSET_ENTITYID}|1527|{TCIN}/(30000,1001)|{TCOUT}/(30000,1001)|{Annotation}|{USE RID}|{DATE}
Where:
{ASSET_ENTITYID} = Is the entityid of your asset. You can find what number it is by issuing:
/Library/Application\ Support/Final\ Cut\ Server/Final\ Cut\ Server.bundle/Contents/Resources/sbin/fcsvr_run psql px pxdb -c "SELECT pxmdvalue.entityid, pxmdvalue.value AS asset_name FROM pxmdvalue INNER JOIN pxentity ON pxentity.entityid = pxmdvalue.entityid WHERE pxmdvalue.fieldid='1543' AND pxentity.address LIKE '/asset/%';"
This will output ALL your assets, so if you know the name or want to parse the name you can use:
/Library/Application\ Support/Final\ Cut\ Server/Final\ Cut\ Server.bundle/Contents/Resources/sbin/fcsvr_run psql px pxdb -c "SELECT pxmdvalue.entityid, pxmdvalue.value AS asset_name FROM pxmdvalue INNER JOIN pxentity ON pxentity.entityid = pxmdvalue.entityid WHERE pxmdvalue.fieldid='1543' AND pxmdvalue.value='ASSETNAME' AND pxentity.address LIKE '/asset/%';"
Where in ASSETNAME you`ll have to put your Asset Name without extension.
{TCIN} and {TCOUT} is, of course, the TC`s points. In the form of: HH:MM:SS;FF
{Annotation} is the commentary.
{USERID} (in my case was 1)
{DATE}: This one is tricky. My example is 2009-03-15 19:31:15.839795-03
So is in the form YYYY-MM-DD HH:MM:SS.????? I really don`t know the rest. Could be milliseconds?
Of course one can write a script to translate everything from a txt file like:
ASSETNAME | TCIN | TCOUT | ANNOTATIONS | USER
But as I`ve said I`m no programmer
Ok.. now the time for the OUTPUT:
The command-line is:
/Library/Application\ Support/Final\ Cut\ Server/Final\ Cut\ Server.bundle/Contents/Resources/sbin/fcsvr_run psql px pxdb -c "SELECT pxmdvalue.value AS Asset_NAME, pxtcmdvalue.value, pxtcmdvalue.begintc, pxtcmdvalue.endtc FROM pxmdvalue INNER JOIN pxtcmdvalue ON pxmdvalue.entityid = pxtcmdvalue.entityid WHERE pxmdvalue.value='ASSETNAME';"
Where ASSETNAME is the Asset name without the extension.
Or issuing the following to OUTPUT ANNOTATIONS from ALL assets:
/Library/Application\ Support/Final\ Cut\ Server/Final\ Cut\ Server.bundle/Contents/Resources/sbin/fcsvr_run psql px pxdb -c "select * from pxtcmdvalue;"
Adding "> /PATHTO_WHERE_IN_WANT/ANNOTATIONSOUTPUT.TXT" at the end will put all output into a txt file.
It`s possible (in theory) to:
1- Create a boolean md field in FCSRV called "EXPORT Annotations" (don`t choose lookup)
2- add or create a md group called "Export Annotations" and add the above md field to it (don`t choose lookup)
3- Add "Export Annotations" md field to Asset Filter md group
4- Make a Response for Running external command. Command path: /Library/Application Support/Final Cut Server/Final Cut Server.bundle/Contents/Resources/sbin/fcsvr_run
Command Parameters: psql px pxdb -c 'SELECT pxmdvalue.value AS Asset_NAME, pxtcmdvalue.value, pxtcmdvalue.begintc, pxtcmdvalue.endtc FROM pxmdvalue INNER JOIN pxtcmdvalue ON pxmdvalue.entityid = pxtcmdvalue.entityid WHERE pxmdvalue.value=[FileName];' > ~/Desktop/ann-out.txt
(I`m having problem with this, it doesn`t work).
5- Make a Subscription that if Export Annotations modified = true, trigger if changed and trigger the Response above.
6- Add exporting annotations md group to Media md set.
In theory it`s possible to modify the FinalCutServerIntegrationSample get and input annotations instead of adding another "comment" field to md group list.
Few!
Ok so please help beautify this out!
This will be very useful for a lot of people.... We know that it`s only a matter of time to FCSVR have this function built-in... but this "time" could be years.
So let`s start ourselves!
Thank you very much!!
Regards!

Selecting separate input and output devices!

hi, i have logic pro 8 and cant find out how to select separate devises for input and output!
for my output (and input when recording drums) i use a alesis multimix 16 (16 track firewire desc) but for recording guitars and bass and poss vocals i would like to use my line 6 x3 live as my input devise but still using the alesis for monitoring.
is this possible? cant figure how to do it.
any help is great help! cheers, Dan

In Logic 9 you can easily select different input and output devices in the Preferences Devices area. In Logic 8 you must create an aggregate device -

Audio input and output at the same time

Hello mac users.
I have one simple question: since the new macbook has one single audio port for both input and output, how could I, for example, play my guitar AND listen to the headphones at the same time?
I KNOW (because I've tried) that with the iPhone headphones with microphone the port CAN physically work at the same time for input and output, so the question is: what can I use to do that? Will a simple splitter do or do I have to use different tricks?
(I know there is a thread on this already, but it doesn't provide a definitive answer)
Thank you!

One of the first questions to ask...
Is the audio input stereo or mono?
When using a headset mic you're dealing with a mono input so you at least know the Mac is capable of that.
If it's mono, and I suspect it is, should be easy to either make or purchase a custom cable that has two female input connectors, one mono input and a stereo headphone input.
However, I'd probably just purchase a USB audio interface, the sound, both recording and playback will be head and shoulders above the Macbooks built in internal audio.

How can I use a different driver for audio input and output?

I did a search of course, and came up with something about an aggregate. I have no idea what this is, how to do it, or if it would even work for me.
What I am trying to do is:
1) Record into Logic Express using my Tascam US-122.
2) Have playback come out of my computer sound system, not the Tascam.
If I go over to the Audio setup window, I can only record when the driver is set to Tascam US-122. Likewise, I can only listen to sound when my Built-In Audio is selected. It gets rather annoying going between the two.
So, would this aggregate thing solve my problem? If so, how do I do it? Thanks for any help!
-allen

Yes it should do what you want.
Go to "Audio Midi Setup", and go to the Audio menu and click "Open Aggregate Device Editor". The interface is pretty simple but if you do get stuck, just use the help function in Audio Midi Setup, as it has a step by step guide.
Then when you return to logic, go to the Preferences>Audio>Drivers section and select Aggregate Device as the new driver rather than either the built in sound or the tascam. Then the inputs and outputs will apply to BOTH devices.

How to use a bluetooth cellphone for audio input and output

Hello, I was wondering how to set-up my Mac Book so that I can use my bluetooth cellphone for audio in and audio out. Ideally, I would like to use my handset for talking on iChat and Skype. Has anyone had any luck doing this? When I bond my cellphone these optiosn do not appear. I know that this is easy to do on a Windows machine but I am not sure about how to do it on my Mac Book.
Thanks!

SSIS: How to use one Variable as Input and Output Parameter in an Execute SQL Task

Hello,
i need your help,I'm working on this issue since yesterday and have no idea how to deal with it.
As I already said in the tilte i want to start a stored procedure via a Execute SQL Task which has around 15 prameters. 10 of these should be used as input AND output value.
As an example:
i have three Variable:
var1    int        2
var2    int     100
var3    int     200
the stroed procedure:
   sp_test
     @var1 int
      @var2 int output
      @var3 int output
   AS
   BEGIN
        SET @var2 = @var2 * @var1
        SET @var3 = @var3 + @var1
   END
So in the Execute SQL Task i call the Stored Procedure as follwos:
    Exec sp_test  @var1 = ?, @var2 = ? output, @var3 = ? output
(I use an OLE DB Connection)
The parameter mapping is as follows:
User::Var1        input                   numeric              0                 -1
User::Var2        input/output         numeric              1                 -1
User::Var3        input/output         numeric              2                 -1
Now my problem. If i set  Var2 and Var3 as Input parameter the values are still the same after running the package. If i set them to a output value the are both Null because the procedure doesnt get any values.
I already tried to list them a second time - like
    User::Var2        input                  numeric              1                 -1
    User::Var2        output                 numeric              1                 -1
or i use a new variable
    User::Var2                  input                  numeric              1                 -1
    User::Var2Return        output                 numeric              1                 -1
but i alwas get the error
"Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done."
Has anybody an idea how I can solve this problem?
Thanks a lot.
Kind Regards,
Alice

Hi Alain,
thx for your answer.
I have around 15 procedures called one after the other to calculated and modify my values. Each procedure is responsible for an other but overlapping set of variables. So i thought it would be a good idea to call them one after the other with the needed variables via a execute sql task.
So if i use a result set, how i get my stored procedure to return 10 values? I would have to use a Function instead of a procedure, wouldn't i?
As if i have 15 procedures this would be a lot of work.
But thanks a lot for the idea. I think an other idea would be to create one function which calls all stored procedures and returns all the calculated values as a result set, wouldn't it?.
Kind Regards.
Alice

How can I make Apple Earphones be the Input and Output for Audio

Is there some way to make Apple Earphones be the Input and Output for Audio in the iMac
This is a problem for me personally as when I am talking to someone on Skype the iMac picks up the In-built Microphone audio, and yes the headphones I'm using do work straight from the iMac as audio output
Any help is appreciated

you can connect the headset to something like this
http://www.ebay.com/itm/NEW-MaelineA-3-5mm-Female-to-2-Male-Gold-Plated-Headphon e-Mic-Audio-Y-Splitter-/381100440348
and then connect the mic to the input and the headset to the headset port

Adapt to output different datatypes and styles are required.
