  • Where does getopt_long store an unrecognized option?

    - by Rob Kennedy
    When getopt or getopt_long encounters an illegal option, it stores the offending option character in optopt. When the illegal option is a long option, where can I find out what the option was? And does anything meaningful get stored in optopt then? I've set opterr = 0 to suppress the automatically printed error message. I want to create my own message that I can print or log where I'd like, but I want to include the name of the unrecognized option.

  • PHP mysql_fetch does not return values

    - by Petr
    Hi, Being quite new with PHP, I cannot find any solution why this does not work. The query is OK and the resource is returned. But I dunno why fetch_assoc does not print values. Thanks $query=sprintf("SELECT ID,NAME FROM USERS WHERE PASS='%s' AND NAME='%s'",mysql_real_escape_string($p),mysql_real_escape_string($n)); $result=mysql_query($query); if ($result) { while ($row = mysql_fetch_assoc($result)) { echo $row['ID']; echo $row['NAME']; } } }

  • Any reason to clean up unused imports in Java, other than reducing clutter?

    - by Kip
    Is there any good reason to avoid unused import statements in Java? As I understand it, they are there for the compiler, so lots of unused imports won't have any impacts on the compiled code. Is it just to reduce clutter and to avoid naming conflicts down the line? (I ask because Eclipse gives a warning about unused imports, which is kind of annoying when I'm developing code because I don't want to remove the imports until I'm pretty sure I'm done designing the class.)

  • Processing large (over 1 Gig) files in PHP using stream_filter_*

    - by mike
    $fp_src=fopen('file','r'); $filter = stream_filter_prepend($fp_src, 'convert.iconv.ISO-8859-1/UTF-8'); while(fread($fp_src,4096)){ ++$count; if($count%1000==0) print ftell($fp_src)."\n"; } When I run this the script ends up consuming ~ 200 MB of RAM after going through just 35MB of the file. Running it without the stream_filter zips right through with a constant memory footprint of ~10 MB. What gives?

  • Can I move another program's window to the front of focus?

    - by TwentyMiles
    I am interacting with a third party application using it's API, and would like to move it to the front of focus (so that it is on top of all other open windows) when a user performs a certain action. While I can move my application up and down in the hierarchy pretty easily, there doesn't appear to be a way to interact with other windows. Is it possible to move another program's window to front with Java?

  • AS3: How to dispatch from the document class?

    - by redconservatory
    I have a pretty good handle on dispatching from classes other than the Document Class, but what happens when I want to dispatch an event from the Document class and have other classes listen to the document class broadcast? It seems like there are several ways to approach this (i.e using a Singleton, using composition, using MovieClip(root)) I was just wondering what people find is the "best practice" way to do this?

  • Multithreaded ActiveRecord requests in rspec

    - by jeem
    I'm trying to recreate a race condition in a test, so I can try out some solutions. I find that in the threads I create in my test, ActiveRecord always returns 0 for counts and nil for finds. For example, with 3 rows in the table "foos": it "whatever" do puts Foo.count 5.times do Thread.new do puts Foo.count end end end will print 3 0 0 0 0 0 test.log shows the expected query, the expected 6 times: SELECT count(*) AS count_all FROM `active_agents` Any idea what's going on here?

  • PHP: Check if it has been one week since timestamp

    - by Rudi
    Hi guys, Let's assume: $time = '2010-05-17 02:49:30' // (retrieved from MySQL TIMESTAMP field) How do I do the following in PHP: 1) Check if it has been more than one week since this time has passed? 2) Assuming "false" on (1), find out how much more time until the one week mark, rounded to days and hours remaining. I know this is pretty straightforward, but it uses a very specific syntax. Having never played with time calculations before, I'd appreciate some guidance. Thanks!

  • Maven: Re-use a POM file in every project.

    - by Zombies
    My goal is pretty simple actually but since there are multiple (and seemingly complex ways to do this) I wonder what I need to do... So I have certain runtime libraries (ADF libraries in particular) that are needed to be added to every project. This parent pom file will just have JAR dependencies in it. How can I use this pom file from a child pom file?
