In a perl script, I'm trying to accept input without blocking and without echoing the characters entered (The script is producing output and I want to have 'hotkeys' to alter its behaviour).
I got as far as using
use Term::ReadKey;
ReadMode( "cbreak", STDIN );
if($input = ReadKey($pause_time, STDIN)){
#process input
}
But once the user types anything then the script stops until a newline is entered. I'd like the input to be processed per-character, without waiting for a newline.
here is task

We have two installations of DB2.
When defining a foreign key with a long name, it works fine on one instance, but not on the other (we get a SQL0107N Name too long - max length is 18).
What is causing this different behaviour? Is there a parameter we can change or is it version dependant?
Hi
I have a table with the following structure:
id int(11),
name varchar(250)
I have lots of records in the table but when I am trying to find a particluar record which has the following value on the name field:
Lorem ipsum d\'olor sit amet
The query is simply returning a blank recordset. I am not being able to figure out this weird behaviour, when my query is as simple as follows:
SELECT * FROM slot_games WHERE name='Lorem ipsum d\'olor sit amet'
Would appreciate your help please! Thanks in advance.
How would you find out the width of a element that is wrapped by 20 odd other elements, but the only fixed width I know is the main wrapper's which is 800px. All child elements are generally blocks, floating or not, with different paddings and margins.
I don't really need the answer to a specific case, I'm just wondering if there are tools or tricks to quickly calculate such things.
Thanks
I have a grouped table view that does not need to scroll. I'd like each cell to highlight as the user moves their finger down the screen and call didSelectRowAtIndexPath on release.
This behaviour can be seen done by apple in 'settings mail add account'?
I can't seem to replicate it myself, all I can get is the default, where the cell deselects as soon as the user moves their finger.
Why when I click on the x button to close the window in a Java application only the window dissapears and the applicaton is still running.
I've read so many times that java designers tried to cater Java behaviour for the most common needs of programmers and save they precious time and so on and so on. What's more common case than closing app when I click on a X button?
Whenever i select something in visual mode it automatically gets copied. It causes a problem since i have alread something in clipboard to paste in that selected text. Is there any way to disable this. Is this due to the fact that my xterm also has similar behaviour

hi,
Upon page reload, all the nodes expand and then only the selected node
remain expanded which is the desired behavior. However, I'd like to
prevent all the nodes from expanding upon refresh as it creates a
flicker. Has anyone else experience this behaviour? How can I turn it
off?
Thanks

Hi...
Before the PHP Version update I used to be able to include files as following without specifying the document root:
<?php include '/absolute/path/to/files/file1.php'; ?>
However I now have to include the same file as following:
<?php include $_SERVER['DOCUMENT_ROOT'].'/absolute/path/to/files/file1.php'; ?>
What php.ini setting could have overridden the former behaviour?
Hi,
I am using VideoView in Android for displaying streaming videos.
While playing the videos if a user receives & disconnects the call , the video starts playing from beginning instead of the behaviour which should be that after the call disconnection , the video should start playing from the same place when the call was received.
Kindly provide your suggestions/sample code if you have already implemented the same.
Warm Regards,
CB

hi, i have a few programs that check if file exist, and if its old version delete him and paste the new one. However under Windows 7 Professional i can't delete the file some System process is always restoring it (same with the dll files) and as you can imagine a lot of programs are crashing because of that behaviour. So WHAT SERVICE/PROCESS can lock/recreate/restore files? I have disabled System Recovery.
I got this odd error and I can't figure out where it came from:

Please run it on the latest versions of all browsers, and see for yourself. When the button is clicked, on:
on Chrome (and Safari of course) it just doesn't select anything, instead creates some ghostly empty option
on Firefox and Opera, it works the way I expect and want it to work, resets the element value
on Explorer, it does nothing
So, which one is expected behaviour? Thanks.
I have a navigation bar which i push 2 navigationBarIems without animation (animate:NO).
I am animating the transition from views, so i don't want those items to animate atomatically. The problem is that when i touch the button from the bar to go to the previous view in the stack, it DOES get animated. How can i change that behaviour?
I have the following situation: I need to sort trees based by height, so I made the Tree's comparable using the height attribute. However, I was also told to overwrite the equals and hashCode methods to avoid unpredictable behaviour.
Still, sometimes I may want to compare the references of the roots or something along those lines using ==. Is that still possible or does the == comparison call the equals method?
In a set of radio buttons of the same group, only one can be selected at the same time. I would like to have the same behaviour with a normal button.
Imagine there's a row of 3 buttons. When a button is selected it changes: but.setSelected(true) and the other two buttons should be NOT selected: but.setSelected(false)
Now, is there a generic, simple and clean solution to accomplish that in Java (Swing) ?
In report preview, if i want see the data only in even pages or odd pages or if i want check the even pages only. Is it possible or not? If it's possible could u plz tell me how to do that?
For some odd reason the part where objects are shown and hidden in my script doesn't seem to be working. I'm not sure if its the fact firefox doesn't like that or whether its the function-based code I have (to save duplicating lines of code)?
There is a working example here and the javascript is here
All help appreciated
