  • C++ Class Construction and Member Initialization

    - by anachoret
    The first print shows the member value to be false, and the other two prints show it as true. Why does the first output differ from the last two? #include #include using namespace std; class MyClass { public: bool value; bool stuff; }; class Container { public: vector my_classes; Container() { MyClass c; cout

  • Adding Refresh Tag to View

    - by RJL
    I need a view to refresh automatically every 20 seconds, and have added the following code to the view header via the views GUI - with no success. The code (or portions of it) are simply displayed on the view and no updating is performed. I've tried omitting both and just the ending ?php statement. If someone can tell me the proper code to use, or a better approach at updating the view automatically, I'd be very appreciative. Thanks. print ";

    - by user246114
    Hi, I am using a third party library that provide some callbacks for a widget, but I'm not sure what the callback parameter objects are (no docs on them).

  • 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']; } } }

  • Why is the PrintDialog not displaying (in 64 bit)?

    - by Bill
    This code, when built in .Net for Any CPU platform and running on a 64-bit machine, simply returns a DialogResult of Cancel without showing the expected dialog box. Dim dlg As New System.Windows.Forms.PrintDialog If dlg.ShowDialog() = Windows.Forms.DialogResult.OK Then '... print the document ' End If However, it works fine when the application is built for the x86 platform, and run on a 64-bit machine. How can you display the dialog with a 64-bit compile?

  • 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?

  • 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.

  • A good Java library for network math

    - by perilandmishap
    I'm looking for a Java library that is geared towards network math and already tested. Nothing particularly fancy, just something to hold ips and subnets, and do things like print a subnet mask or calculate whether an IP is within a given subnet. Should I roll my own, or is there already a robust library for this?
