Getting output from my MBP to LCD TV

Read any postings in this forum but could not find an answer. I have Apple's mini displayport, a DVi to HDMI cable and the appropriate audio cables.
After connecting the MBP to the LCD TV I can see the desktop on the TV**. However when I closed the lid the TV goes black. With the lid open I run front row and it work on the MBP screen and on the TV I only get the same desktop image**
What am I doing wrong?
** By the way the desktop picture in my MBP doesn't show. What it shows on the TV is the apple desktop purple "galaxy" image. Interesting!

eew and Network 23,
Thanks for adding to my post. It is very clear now. One of the problems I had is that I didn't realize that in System Preference>Displays, the menu changes a bit if you have the monitor connected or not.
Two more questions,
1) Based on your suggestions I prefer the extended desktop mode to preserve higher output resolution. I guess that when you have Mirroring off, it automatically means that you have the Extended Desktop option on, right?
2) I cannot get the whole thing to work when I close my MBP. The TV goes black. I have an external mouse and keyboard (both bluetooh). I played with the "Arrangement" setting but nothing. What am I doing wrong.
Thanks in advance.

Error Getting Output From ICloudTask

I went through the Azure Batch Tutorial for .NET and am having issues with getting the output from the ICloudTask. After waiting for the tasks to complete I have the coded below:
foreach (ICloudTask task in listjob.ListTasks())
string taskFileContent = task.GetTaskFile(Constants.StandardOutFileName).ReadAsString();
Console.WriteLine("Task " + task.Name + " says:\n" + taskFileContent);
It throws a System.AggregateException on task.GetTaskFile with an inner exception of:
{"The remote server returned an error: (404) Not Found."}
I did some research but haven't been able to determine why I am getting this error?

I see in the sample that the second use of TaskStateMonitor (TSM) does not check for timeout... We will add this and you might want too as well.
If the TSM times out you might want to confirm the pool has VMs and that they reach TVMState.Idle (i.e.: are available to run tasks).
You do not mention the exact task state you see but it is possible for a task to be in the TaskState.Completed state and still not have a stdout.txt file.
You could list the files with ICloudTask.ListTaskFiles(recursive: true) to see what files are actually there.
Also you can check the exit code (ICloudTask.TaskExecutionInformation.ExitCode) and/or the the TaskSchedulingError (ICloudTask.TaskExecutionInformation.SchedulingErrro) to see if the task ran correctly.

ps: don't forget to ToString() the inner BatchException. I posted to the forum earlier on this and there are data in the exception that can tell you more than "not found"...

Not getting outputs from JavaScript Patch in QC2

The JavaScript Patch no longer generates outputs from outputs[n]. The outputting of data just stopped.
An example output generator (no other instructions in the JavaScript patch):
outputs[0] = "string";
was sent to an Image With String patch and then to a Billboard patch (the only existing patches). No text appeared in the viewer. When in Editor, the cursor placed over Output #0 shows only:
Type Virtual
with no value. The input string into Image With String shows "".
When disconnecting the JavaScript patch from the Image With String patch and I entered "help", the text help appeared in the viewer.
I reinstalled Quartz Composer and there was no change. Anyone have any idea what is going on?

What I've learned: the Tascam 122L has known issues when working with Leopard. Back in the store, I plugged another external card (Presonus Audiobox USB), which immediately worked with the Mac as though they were friends since birth.
I am rapidly warming to Mainstage.

Video Output from 15in MBP

Hi All,
I am looking for a way to output video from my 15in MBP to a ViewCast GoStream(has component and s-video inputs). Currently, the only solution I have found is the Matrox MXO, which would work, but before I go and spend a whole grand to buy it, I was wondering if there were any cheaper alternatives.
Thanks in advance!
Matrox MXO - http://www.bhphotovideo.com/c/product/434990-REG/MatroxMXON_MXO_External_HDand.html

Hi -
Is your 15" MBP old enough to have an express34 card slot?
If so, take a look at the Matrox Mini, or a more ruggedized version, the Matrox LE:
http://www.bhphotovideo.com/c/product/618347-REG/MatroxMXO2_MINIL.html
http://www.bhphotovideo.com/c/product/650569-REG/MatroxMXO2LE_NL.html
If you have a current MBP, then your options are limited - which is why many lament the passing of the express34 card slot.
Hope this helps

Getting output from an OS command from an ABAP program

Hi Folks!
I have a requirement, is it possible to call an operating system command, and also get its output back to the ABAP program that has called it?
For example, from an ABAP program calling the "dir" command from Windows and getting back (as a string) the directory listing to the ABAP program?
Thanx in advance!
Juan.

Getting output from a C programme

Hi
I am trying to execute a C programme (.o file) on Solaris and get its output .
The C programme is a simple function which returns 0 or more then zero after executing some logic .
I tried to use Runtime.exec() method but was not able to get any out put from the function , where as I did same in a perl script and was able to get the output .
I have even tried to get error stream , input stream but I always get -1 as a return value .
Following is my program
Runtime rt = Runtime.getRuntime();
String[] arg =new String[]{"program","arg1","arg2"};
Process p =rt.exec(arg);
BufferedInputStream buf = new     BufferedInputStream(p.getErrorStream());
int data=buf.read();
System.out.println("date is "+data);
BufferedInputStream buf1 = new     BufferedInputStream(p.getInputStream());
     while((data=buf1.read())!= -1)
          System.out.println("data input is "+data);
arg1 and arg2 are 2 arguments that the program needs . It always returns a value with might be 0 or non zero.
I know I can try to use JNI , but i beleive using Process is a simple solution (if it works)
Thanks

.o files are usually no executables but object files. They need to be linked (with an object including the main funtion) to yield an executable.
Shared objects are usually called *.so.

Get files from old MBP to new MBP when the old one has suffered a Logic Board failure

Recently, my 2009 unibody MacBook Pro died. Logic board failure, I am told. It is out of warranty, and replacing the Logic Board would cost a grand. It had some other issues too, so I figured upgrading to a brand new system would be the best idea. So, I am going to purchase a brand new one within the next few days. My question is this: How to I get the files from my old MBP (I NEED them, plain and simple) to the new one once I get it? Should I take out the harddrive from the old one and connect it via a SATA>USB cable and connect it to the new one? Can anyone shed any light on this? It will be much appreciated. Thanks.

Yep, all you need is a IDE/SATA to USB adapter for about $20 online at OtherWorld Computing, NewEgg and other online computer sites like Amazon etc.
You can find the screwdriver or other torx driver at iFixit or OtherWorld, just look for your Mac model or just be rough with it and drill out the screws.
You can choose to get a enclosue and use the drive as a external drive, it will cost more naturally, but for a few bucks more though you can get a brand new external drive and likely twice the capacity.
Some external drives can't be Carbon Copy Cloner and option booted from, so perhaps a adapter is best. (don't clone a OS from another Mac to your new Mac)
Setup:
When you set up the new Lion Mac, name the hard drive the same name as the external drive, also setup the same user name as the old Mac had. Software Update.
Install all your known third party programs from fresh sources as many as possible.
The last thing you do is connect the old Mac drive, transfer all the files from the user folders right back into their respective folders on the new drive (Music, Pictures, Documents etc) Not User/Library.
Open all your programs like iTunes and iPhoto and it will update for your files, then go through the folders and delete what you don't want.
Don't use migration or setup assitant, it's a blind copy, includes programs you can't use anymore and other headaches.
If you do things in the order I specify, your drive will be optimized and run fast for a decent amount of time.
If Lion act's glitchy, Carbon Copy Cloner to a new HFS+ Journaled (Disk Utility) and then hold Command R to get into Lion Recovery, Zero Erase the OS X Lion partition and then option boot from the Lion clone and reverse clone onto the OS X Lion partition on the internal.
You can also reinstall Lion on top of the factory Lion from the Recovery Partition.
search "apple support Lion Recovery" for details.

Getting output from StreamRedirectThread.java

Hi,
For the purpose of my work, I am trying to store the output that is produced by StreamRedirectThread.java into a vector as shown in the code below. When I try to print out that vector the output is not as the same as it is printed in the StreamRedirectThread.java program. For example if the output form the program prints out the numbers form 0 to 5, the vector output is doubled in size and prints:
index = 0 content=0
index = 1 content=
index = 2 content=1
index = 3 content=
index = 4 content=2
index = 5 content=
index = 6 content=3
index = 7 content=
index = 8 content=4
index = 9 content=
index = 10 content=5
index = 11 content=
Can anybody advice me what to do about it. I tried but couldn't fix it. The code of StreamRedirectThread.java is as
import java.io.*;*
*import java.util.*;
import com.sun.jdi.*;*
*import com.sun.jdi.request.*;
import com.sun.jdi.event.*;*
*import com.sun.jdi.connect.*;
class StreamRedirectThread extends Thread {
private final Reader in;
private final Writer out;
private static Vector outvector = new Vector(0); // victor of objects that contains output result
private static final int BUFFER_SIZE = 2048;
* Set up.
* @param name Name of the thread
* @param in Stream to copy from
* @param out Stream to copy to
StreamRedirectThread(String name, InputStream in, OutputStream out) {
super(name);
this.in = new InputStreamReader(in);
this.out = new OutputStreamWriter(out);
setPriority(Thread.MAX_PRIORITY-1);
public void run() {
try {
char[] cbuf = new char[BUFFER_SIZE];
int count;
while ((count = in.read(cbuf, 0, BUFFER_SIZE)) >= 0) {
//out.write(cbuf,0,count);
String s = new String(cbuf,0,count);
if (!(s.equals(null)))
TemplateApp.vv.addElement(s);
outvector.addElement(s); out.write(s);
out.flush();
} catch(IOException exc) {
System.err.println("Child I/O Transfer - " + exc);
public synchronized static Vector getOutVector()
return outvector ;
}Thanks a lot for help

The problem was with endline stored in the vector. I did the follwing and it worked for me.
String separator = System.getProperty("line.separator");
while ((count = in.read(cbuf, 0, BUFFER_SIZE)) >= 0) {
             if ( count == 0 ) {
                continue;
             String s = new String(cbuf,0,count);
             out.write(s);
             out.flush();
             s = s.replace(separator, "");
             if (s.length() !=0 )
                        outvector.addElement(s);
       }

Not getting output from pic-servo board

Greetings everyone and thanks in advance. I wish to use a Pic-Servo SC controller board (http://www.jrkerr.com/) to control a single stepper motor, using LabView. Here's what I've done so far:
-I already have installed 32 and 64 bit LabView (2011) and tried the test program in both
-VISA controller is properly installed
-USB to Serial FT232R converter is also installed, and configured in 19200 baud rate
-COM3 port is shown as the assigned port for the controller, and selected as such in LV
So far, I have managed to get the test program to run without communication errors, but upon sending any commands to the motor, it is completely unresponsive and behaves like it has no current or controller attached, despite it being configured in the basic 1-motor setup specified by Jrkerr site.
Any help, comment or suggestion about how I could manage to get the motor moving will be welcome.

Van you attach the manual? I get an error every time I try. I'm not convinced that it is RS485 from the brief product description. It talks about buying a RS232-RS485 adapter to communicate to multiple controllers.

Can not get output from Objective DAC without Pulseaudio [SOLVED]

I have owned the ObjectiveDAC/O2 Amp combo for a couple of months now. Unfortunately I was unable to get the device to function properly without pulseaudio installed. When trying to configure it on a pure alsa system, I can set it as the default control card in alsamixer. The issue is that when I set it as the default pcm device, it fails to work. I can select the device in pulseaudio fine, and my system recognizes the device in alsa, however I cannot, for some reason, actually use the device. It seems that pulseaudio butchers sound quality, and I would greatly appreciate any help being able to get my device working without it. I can't believe that any sane individual would actually make part of the audio stack downmix audio by default.
It was just a lack of understanding of Alsa's config syntax. I do apologize for taking up space on the forums. I now have Alsa running with my DAC just fine.

Yeah that's what I meant. Try to burn a new cd at a slower speed. When the new one is done create a hashsum of the new burn and compare it to the iso you used to burn it with. I only say this because a few times in the past when I had sr0 errors while booting live cds it was because the disk was messed up and I had to burn it again.

Why can't I get iCal from my MBP to sync to the calendar on iPhone 3GS?
