Executing a native process and getting the text output
Hi,
I have the following problem.
When I execute a native DOS process (lets say a batch file), and
expect some text output from this process I use the following code:
String command = "test.bat";
Process process = runtime.exec(command);
BufferedReader rd = new BufferedReader(new InputStreamReader(process.getInputStream()));
String s = new String();
while((s = rd.readLine())!=null) {
out.println(s + "<br/>" );
The problem is that as long as rd.readLine() does not return null, the page does not display the result. When the process crash, sometimes nothing return.
I would like to display the output as it comes, i.e. line by line.
I have no clue on how to do that except writting the output in a text file, and reading the text file with a page that reload every x seconds.
I do not beleive this is a good solution.
Additionaly, I may have a huge output. It seems to make the process
to hang. Is there a was to fix it.
Could someone give me some hints.
Regards,
Arnaud.
I am having the same problem...did you ever solve it?

Getting the text of a Button when it is being read as a Node. Looping VBox
I'm learning JavaFX and this is just a small programming question.
I have 3 buttons in a VBox. And I want to apply the same 3 effects on all buttons after I put them in the Vbox. But when I use a for loop and getChildren() on the VBox, they are returned as 'Nodes'. I can't use the Button.getText() to find out the text of the button.
Is there a way I can getText of a Node? Or maybe convert the current Node to a Button and get the text that way?
VBox vbox = new VBox();
Button option1= new Button("First Button");
Button option2= new Button("Second Button");
Button option3= new Button("View Rules");
vbox.getChildren().add(option1);
vbox.getChildren().add(option2);
vbox.getChildren().add(option3);
for (final Node button : vbox.getChildren())
button.setOnMouseEntered(new EventHandler<MouseEvent>()
@Override
public void handle(MouseEvent arg0)
button.setEffect(addEffect(Color.web("#53CFA6"), .8, 10));
button.setOnMouseExited(new EventHandler<MouseEvent>()
@Override
public void handle(MouseEvent arg0)
button.setEffect(addEffect(Color.web("#FF6800"), .8, 10));
button.setOnMouseClicked(new EventHandler<MouseEvent>()
@Override
public void handle(MouseEvent arg0)
button.setEffect(addEffect(Color.web("#E62800"), .8, 10));
//Need to use button.getText()
//Button button; button.getText() works
}Hello user,
You should have formatted your code properly. Look in the forum guides to format the codes.
For getting the instance of Button , You need to do it safely
There are two ways to get instance of Button.
for (final Node button : vbox.getChildren()){
Button b = null;
if(button instanceof Button){
b = button;
if(b != null){
//Do your stuffs here
}Or You can even do like this too
for (final Node button : vbox.getChildren()){
Button b =null;
try{
b = (Button) button; //casting the class
catch(ClassCastException e){
e.printStackTrace();
if(b != null){
//Do your stuffs here
}Thanks

I recently bought a new macbook pro and set it up using the migration assistant from my mac mini. I can't get the text message forwarding feature to work with both computers. It keeps saying that I only have 2 devices setup, my iPad and my macbook pro. When I mess with the setting on my mac mini, it goes from saying that that is one of the devices to my macbook pro being the 2nd device. I think that something happened as a result of my using the migration assistant and now it thinks that my macbook pro and my mac mini are one and the same computer. Any ideas?
Thanks, Sig.
The old computer is a 2.6 Ghz Intel Core 2 Duo
The new one is a 2.3 GHz intel core i7
In going over this, thanks to "tallking it out" with you, I did discover the Text Edit problem. Because I've still been unable to get the new computer text size (fonts or whatever) to match the old computer, I did not notice that the curser is now different--the line midway down the curser has to be placed on the line I am working upon, otherwise the edits go elsewhere on the page. Now, with a bit of difficulty, I am able to get Text Edit to work correctly.
If you have any ideas as to why my menu bar and Text Edit type are still so slow, I'd love to have them.
(I went through the process you suggested earlier, re my Trackpad preferences, and found no improvement.) -
When I import video and place it into timeline as a raw file with no fx or any added processing I get the message that the video is unrendered and therefore it doesn´t playback?
FCE can use DV or AIC video formats natively. Any other format will need to be converted to one of those two if you want to avoid constant rendering. The clips you use must match the Sequence settings.

I tried to install yosemite yesterday and my computer goes through the whole installation process and then to a blank white screen. I've rebooted, I've reinstalled several times and get the same result. Two days wasted and I can't use my computer!!
I don't know if you've already resolved your problem, but I had the same thing, it took me 6 hours to fix it. I had the exact same as you, installed the update and then it went to a white screen. After trying start up holding down cmmd r or holding down the alt key to try to install it again, nothing worked, same result every time. Then an angel came to me here somewhere but I can't find it now to thank him. Start in safe mode, press shift once you hear the start up chime and hold it down until you hear it again. Installation completion box came up and it was working. turn off computer and start up again normally and all is well. Except my final cut pro x doesn't work with it, have to update that now too. same as when I updated to mavericks.
Hope this helps. -

When and How to get the Text.ScrollPos value of a String control when scroll bar position changed
Hi,
I'm working on a feature triggered by scroll bar position of a string control changed.
But I could not find a good way to catch the scroll bar position changed event,
the scroll bar is controlled manually by mouse down → mouse move → mouse up, I want the get the Text.ScrollPos value when user mouse up, and compare with the maximum value.
But the problem is, mouse up on the scroll bar could not trigger String: Mouse up event!
So I have to get the Text.ScrollPos continuously in the background in Timeout event, but I think it’s not efficient.
Do you have any better idea on when to get the correct destination value of Text.ScrollPos?
I plan to store the value of Text.ScrollPos in the bottom(maximum value) in a shift register, then compare the current Text.ScrollPos value with the max one.
If it comes close to the bottom(90%~100% of the maximum value), then the close to bottom LED will turn on.

scroll bar pos changed.vi 15 KBHello Cecilia,
I don't think there is any build-in event for this.
One solution would be to create your own user event at the initialisation of you main and launch a thread which is going to be pulling the value of your scrollbar position:
Then you can build your main as if they were a scrollbar move event.
And dont forget to close the thread and destroy the event at the end.
Hope it helps.

HOWTO Get the text of "combo box" and "labe" controls with JavaAccessBridge
HOWTO Get the text of "combo box" and "labe" controls with JavaAccessBridge.
Please help,
I'm trying to use the Java Access Bridge (JAB) 2.1 to get the text in Java Applet controls. I've been able to use the sample code in AccessInfo.cpp sample that comes with JAB to get text from "text" controls in a Java Applet. To clarify, I am referring to the "role" in the AccessibleContextInfo struct being set to "text" or "combo box" or "label".
The problem is, when I use the AccessInfo.cpp sample to get text from a "combo box", the accessibleText data member comes back as FALSE, and thus any of the JAB text functions like GetAccessibleTextInfo fail to get any text information from "combo box" or "label" controls.
I've also tried GetCurrentAccessibleValueFromContext on the "combo box" and "label" controls, but the text returned is empty.
Can anyone help?I have new information in regards to this issue. A contact from Sun did get to me in email and relayed that that "label" objects store their text in the "name" data member of the AccessibleContext structure. This was a big help.
But I'm still stuck trying to get information from "combo box" and other controls, like "push button". The contact said, the Java Access Bridge does not provide all the information because it is already implemented by other interfaces like AccessibleComponent, AccessibleAction, or AccessibleSelection. The contact did not allude to whether these opther interfaces can be used along side the Java Access Bridge or not. So, I'm left a step closer to the goal, but still stuck without the full solution.
Can one take the Java Access Bridge functions, like say those used in the Ferret sample, and close the gap to get text back from "combo box", "push button", and other controls by using some other API in conjunction? -

Why do I get the text notification when still in the text and someone responds?
When I am texting with someone and the text is still showing on the screen I get the text notification every time they respond.
I have my text tone set to tri-tone, reminder alerts to none and vibrate off.
It wasn't always like this and it's driving me nuts.
Thanks for any help you can give me.Someone answered in another thread. They told me to turn the phone off and wait a minute or 2 before turning it back on and it worked! Just thought I would share in case anyone else was having this problem.

When I get messages from Barnes and Noble, the text is blank. If I hit reply or forward, I can then see the content. This only happens with Barnes and Noble. Any suggestions on how to view the content?
I'm sorry, but your sister, unless she had already turned on the "Find my iPhone" feature and the person who took the phone has not disabled it, is out of luck. She should report the theft to local police authorities, including the serial number of her iPhone. While her experience is unfortunate, there are good reasons why Apple cannot do anything else about it.
I hope she gets her phone back.
Best of luck. -
