  • Simple "Hello World!" console application crashes when run by windows TaskScheduler (1.0)

    - by user326627
    I have a batch file which starts multiple instances of simple console application (Hello World!). I work on Windows server 2008 64-bit. I configure it to run in TaskScheduler, at startup, and whether user is logged-in or not. The later configuration means that the instances will run without GUI (i.e. - no window). When I run this task, some of the instances just fail, after consuming 100& CPU. Application event-log shows the following error: "Faulting module KERNEL32.dll, version 6.0.6002.18005, time stamp 0x49e0421d, exception code 0xc0000142, fault offset 0x00000000000b8fb8, process id 0x29bc, application start time 0x01cae17d94a61895." Running the batch file directly works just fine. It seems to me that the OS has a problem loading too many instances of the application when no window is displayed. However - I can’t figure out why... Any idea??

  • C++ build systems

    - by flo
    I will start a new C++ project (it may have some C components as well) soon and I am looking for a modern, industrial-strength (i.e. non-beta) build system. The software will be created by several developers in 3-5 years and will run on Linux (Mac OS X and Windows might be supported later). I am looking for something that has better comprehensibility, ease-of-use and maintainability than e.g. make but is still powerful enough to handle a complex project. Open source software is preferred. I started looking into Boost.Build, CMake, Maven and SCons so far and liked features and concepts of all of those, but I'm lacking the experience to make a decision for a large project.

  • Multiple sections on landing page only

    - by RDRAO
    Hi every one, I am very much new to Drupal but am loving it to start with. I got struck at a point with respect to theaming. I have a region called 'footer-teaser' just above footer. Its width is 800px. its been split into 3 equal size columns. Each column has the following. Image of size 120x120 Some teaser text Link to 'read more' The design requirement is all the above should be editable by the admin from the admin interface. If its static i would have hardcoded this but since the requirement is dynamic, i am not aware of how to achieve this. I have customised page.tpl for other sections of the page except this. I am sure someone else would have faced this issue before and was wondering if anyone can direct me in the right direction? Even better if an example is provided. Cheers RD

  • Copy an array backwards? Array.Copy?

    - by daniel
    I have a List<T> that I want to be able to copy to an array backwards, meaning start from List.Count and copy maybe 5 items starting at the end of the list and working its way backwards. I could do this with a simple reverse for loop; however there is probably a faster/more efficient way of doing this so I thought I should ask. Can I use Array.Copy somehow? Originally I was using a Queue as that pops it off in the correct order I need, but I now need to pop off multiple items at once into an array and I thought a list would be faster.

  • flash.media.Sound.play takes long time to return

    - by Fire Lancer
    I'm trying to play some sounds in my flash project through action script. However for some reason in my code the call to Sound.play takes from 40ms to over 100ms in extreme cases, which is obviously more than enough to be very noticeable whenever a sound is played. This happens every time a sound is played, not just when that sound is first played, so I dont think its because the Sound object is still loading data or anything like that... At the start I have this to load the sound: class MyClass { [Embed(source='data/test_snd.mp3')] private var TestSound:Class; private var testSound:Sound;//flash.media.Sound public function MyClass() { testSound = new TestSound(); } Then im just using the play method of the sound object to play it later on. testSound.play();//seems to take a long time to return This as far as I can tell is following the same process as other Flash programs I found, however none of them seem to have this problem. Is there something that I've missed that would cause the play() method to be so slow?

  • How to programmatically deactivate the AirPort?

    - by mystify
    I want to make a small utility to programmatically deactivate the AirPort of my mac. I have networking problems which couldnt be resolved by expensive experts. I need to deactivate and reactivate the mac AirPort once every half hour. So a little utility which does that automatically would be great. I think I wouldn't need an UI for this either. Just the most simple possible kind of application to automatically stop and start the AirPort. Maybe even apple automator code?

  • Strange WPF Behaviour With WCF Async calls

    - by gvigsgb
    I have a WPF application calling WCF via Async calls. The application has four tabs in which each are loaded from seperate async calls, each tab has a busy indicator. The problem: When running within Visual Studio I can click a refresh button on each tab and each tab's busy indicator starts and the data is retrieved from the WCF service. As each tab's data comes back it is refreshed. When I deploy the application via one click the application's UI hangs after only two tabs start refreshing. So in this case I press refresh on tab one, then on tab two and the application hangs until one of the two tabs data comes back. I thought at first that it was something to do with the WCF service throtteling and that was not the case as both the Visual Studio and the One Click deployments of the application point to the same service. Anyone have any ideas on where to look? I cannot reproduce the hang issue within Visual Studio?

  • pthreads recursively calling system command and segfault appears

    - by jess
    I have a code base where i am creating 8 threads and each thread just calls system command to display date in a continuous cycle, as shown below: void * system_thread(void *arg) { int cpu = (int)arg; printf("thread : start %d\n", cpu); for (;;) { // date ã³ãã³ãã®å®è¡ if (mode == 0) { system("date"); } else { f_hfp_nlc_Fsystem("date"); } } sleep(timerval); return NULL; } This application segfaults after running for 2-3 seconds, due to following 2 reasons: 1. read access, where the address is out of VM area 2. write acces, where it does not of write permission and its trying to modify some structure.

  • Does Python Django support custom SQL and denormalized databases with no Foreign Key relationships?

    - by Jay
    I've just started learning Python Django and have a lot of experience building high traffic websites using PHP and MySQL. What worries me so far is Python's overly optimistic approach that you will never need to write custom SQL and that it automatically creates all these Foreign Key relationships in your database. The one thing I've learned in the last few years of building Chess.com is that its impossible to NOT write custom SQL when you're dealing with something like MySQL that frequently needs to be told what indexes it should use (or avoid), and that Foreign Keys are a death sentence. Percona's strongest recommendation was for us to remove all FKs for optimal performance. Is there a way in Django to do this in the models file? create relationships without creating actual DB FKs? Or is there a way to start at the database level, design/create my database, and then have Django reverse engineer the models file?

  • Playing Ogg Sound in Android

    - by baba tenor
    In my application, I am trying to play a sound file in ogg format, stored in raw folder in res directory of my application. When I press the button that calls below function, it just freezes with the button pressed and does not respond. In the end, I have to terminate the application from Eclipse. Nothing about an error or exception in Logcat. In debugging mode, it enters create function and never comes back. What am I doing wrong? private void playbeep() { mPlayer = MediaPlayer.create(this, R.raw.beep); mPlayer.start(); mPlayer.release(); }

  • Delphi : Restore a pre-design tabsheet after user has closed it...

    - by rusty
    Hello, I have a tPageControl on a form, and have made a nice 'welcome page' as a new ttabsheet at design time for the user to start off with. However, if the user closes this tab, I would like the option to bring it back, as it was in originally (much like the welcome page in the Delphi IDE). This seems like a simple problem... When the tab closes, the original sheet is freed and set nil. I tried creating the sheet again by name (e.g. tabsheet1 := ttabsheet.create) and assigning it to the pagecontrol, but none of the original components from the sheet are there anymore... I know designing the welcome page as a separate form, creating it when I need it and slapping it into a new tabsheet would work... but I was just wondering if there was a way to do it with the design time tabsheet. Thanks all! Rusty

  • Pagination links do not work after first page

    - by TheStack
    Hello, I am trying to fix this pagination script. It seems when I click on the pagination links [1][2][3][4]or[5] , it doesn't work. It just shows the first page and when clicking on the next numbers nothing happens. I hoping someone can see something in the script that I can not see. The main page looks like this (pagination.php): <?php include_once('generate_pagination.php'); ?> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js"></script> <script type="text/javascript" src="jquery_pagination.js"></script> <div id="loading" ></div> <div id="content" data-page="1"></div> <ul id="pagination"> <?php generate_pagination() ?> </ul> <br /> <br /> <a href="#" class="category" id="marketing">Marketing</a> <a href="#" class="category" id="automotive">Automotive</a> <a href="#" class="category" id="sports">Sports</a> Then, generate_pagination.php: <?php function generate_pagination($sql) { include_once('config.php'); $per_page = 3; //Calculating no of pages $result = mysql_query($sql); $count = mysql_fetch_row($result); $pages = ceil($count[0]/$per_page); //Pagination Numbers for($i=1; $i<=$pages; $i++) { echo '<li class="page_numbers" id="'.$i.'">'.$i.'</li>'; } } $ids=$_GET['ids']; generate_pagination("SELECT COUNT(*) FROM explore WHERE category='$ids'"); ?> Here is the jquery file (jquery_pagination.js): $(document).ready(function(){ //Display Loading Image function Display_Load() { $("#loading").fadeIn(900,0); $("#loading").html("<img src='bigLoader.gif' />"); } //Hide Loading Image function Hide_Load() { $("#loading").fadeOut('slow'); }; //Default Starting Page Results $("#pagination li:first").css({'color' : '#FF0084'}).css({'border' : 'none'}); Display_Load(); $("#content").load("pagination_data.php?page=1", Hide_Load()); //Pagination Click $("#pagination li").click(function(){ Display_Load(); //CSS Styles $("#pagination li") .css({'border' : 'solid #dddddd 1px'}) .css({'color' : '#0063DC'}); $(this) .css({'color' : '#FF0084'}) .css({'border' : 'none'}); //Loading Data var pageNum = this.id; $("#content").load("pagination_data.php?page=" + pageNum, function(){ Hide_Load(); $(this).attr('data-page', pageNum); }); }); // Editing below. // Sort content Marketing $("a.category").click(function() { Display_Load(); var this_id = $(this).attr('id'); $.get("pagination.php", { category: this.id }, function(data){ //Load your results into the page var pageNum = $('#content').attr('data-page'); $("#pagination").load('generate_pagination.php?category=' + pageNum +'&ids='+ this_id ); $("#content").load("filter_marketing.php?page=" + pageNum +'&id='+ this_id, Hide_Load()); }); }); }); Lastly, filter_marketing.php (when a user clicks the filter link buttons): <?php include('config.php'); $per_page = 3; if(count($_GET)>0) { if($_GET['page']!=''){ $page=$_GET['page']; } if($_GET['id']!=''){ $id=$_GET['id']; } } $page= ($_GET['page']!='') ? $_GET['page']: false; $id= ($_GET['id']!='') ? $_GET['id']: false; $start = ($page-1)*$per_page; if($page && $id){ $sql = "SELECT * FROM explore WHERE category='$id' ORDER BY category LIMIT $start,$per_page"; } else { die('Error: missing parameters. Id= '.$id.' and page= '.$page); } $result = mysql_query($sql); ?> <table width="800px"> <?php while($row = mysql_fetch_array($result)) { $msg_id=$row['id']; $message=$row['site_description']; $site_price=$row['site_price']; ?> <tr> <td><?php echo $msg_id; ?></td> <td><?php echo $message; ?></td> <td><?php echo $site_price; ?></td> </tr> <?php } ?> </table> So, if anyone sees where the problem is occurring and can help rid of the problem, that would be great, Thank you.

  • How to correctly and standardly compare floats?

    - by DIMEDROLL
    Every time I start a new project and when I need to compare some float or double variables I write the code like this one: if (fabs(prev.min[i] - cur->min[i]) < 0.000001 && fabs(prev.max[i] - cur->max[i]) < 0.000001) { continue; } Then I want to get rid of these magic variables 0.000001(and 0.00000000001 for double) and fabs, so I write an inline function and some defines: #define FLOAT_TOL 0.000001 So I wonder if there is any standard way of doing this? May be some standard header file? It would be also nice to have float and double limits(min and max values)

  • What performance indicators can I use to convince management that I need my development PC upgraded?

    - by Aaron Daniels
    At work, my PC is slow. I feel that I can be way more productive if I just wasn't waiting for Visual Studio and everything else to respond. My PC isn't bad (dual-core, 3GB of RAM), but there is a lot of corporate software and whatnot to slow everything down and sometimes lock it up. Now, some developers have begun getting Windows 7 machines with 8 GB of RAM. Of course, I start salivating at this. However, I was told that I "had to justify" why I should get a new machine. I can think of a lot of different things, but I am curious as to what every one else on SO would have to say. NOTE: Ideally, these reasons should be specifically related to .NET development in Visual Studio on a Windows machine. This isn't a "how can I make my machine faster" question.

  • problem with drupal view and php code

    - by czuroski
    Hello, I have a view set up in drupal and I am using some jquery code within the view which hides some data based upon a text box value. Everything is working fine for me when I am logged in. When I log out and access the block anonymously, it doesn't work correctly. I am somewhat new to drupal, and don't know where to begin troubleshooting. I assume it is a permissions issue, but on the view, on the content type, where? If anyone could give me some direction on where to start looking, I would greatly appreciate it. Thanks

  • Controlling Windows Media Player through PHP / batch files

    - by Duroth
    I'm currently writing a tiny webapp for my HTPC (actually, a PC serving as both a media player and web- / fileserver) that will allow me to remotely control the playing of audio, without having to turn on my TV just to switch songs. I'm using Windows Media Player as my audio player of choice, and I thought I could control it through PHP's COM Class. Unfortunately, I've not been able to find any documentation or examples on controlling WMP through this interface. Can anyone point me in the right direction here? A second (and much less preferable) solution would be to use PHP's exec() call to start batch files that, in turn, control WMP.

  • Flatten old history in Git

    - by schoetbi
    I have a git project that has run for a while and now I want to throw away the old history, say from start to two years back from now. With throw away I mean replace the many commits within this time with one single commit doing the same. I checked "git rebase -i " but this does not remove the other (full) history containing all commits from git. Here a graphical representation (d being the changesets): (base) -> d1 -> d2 -> d3 -> (HEAD) What I want is: (base,d1,d2) -> d3 -> (HEAD) How could this be done? Thanks.

"House for sale..", - can be quoted -- "house", 'house' - can have exclamation .. house!!!, house! - others - house? etc .. this is why I used %house%

  • EXCEL import to sql returning NULL for decimals when in VARCHAR data type

    - by Daniel
    Hi, I am working on a peice of software which has expodentially grown over the last few years and the database needs to be regularly updated. Customers are providing us with data now on large spreadsheets which we format and will start importing into the database. I am using the Import and Export Data (32-bit) Wizard. One column in the database contains values like '1.1.1.2' etc and i am importing them in as a Varchar as that is the data type in the database. However, for values like '8.5', 'NULL' is getting imported insead. It only occurs when there is one decimal point. Is this a formatting error with excel or is it the wrong datatype?

  • Resharper: how to force introducing new private fields at the bottom of the class?

    - by Igor Brejc
    Resharper offers a very useful introduce and initialize field xxx action when you specify a new parameter in a constructor like: Constructor (int parameter) The only (minor) nuisance is that it puts the new field at the beginning of the class - and I'm a fan of putting private parts as far away as possible from the prying eyes of strangers ;). If, however, you already have some private fields in the class, Resharper will put the new field "correctly" (note the quotes, I don't want to start a flame war over this issue) next to those, even if they are at the end of the class. Is there a way to force Resharper to always put new fields at the end of the class? UPDATE: OK, I forgot to mention I know about the "Type Members Layout in Options" feature, but some concrete help on how to modify the template to achieve fields placement would be nice.

  • Neat way of gettings position of my Object in linq collections

    - by Steve
    I currently have a object called Week. A week is part of a Season object. the season can contain many weeks. What I want to do is find the position of my week (is it the first week in the season (so #1) or is it the second (so #2). int i = 0; foreach ( var w in Season.Weeks.OrderBy(w => w.WeekStarts)){ if(w.Id == Id){ return i; } i+=1; } At the moment this is what I have. I order the weeks in a second by there start date to make sure they are in the correct order. and I cycle through them until I find the week that matches the week I am currently looking at. and return the int that I have been counting up.. I feel there should be a easier linq way to do this as it feels pretty messy!

  • How can you setup multiple WSGI apps on one server?

    - by Shakakai
    I'm working on a python based server product where a user can install WSGI-based python apps on their server. I can enforce any restriction on the application structure or format to make this easy. The user workflow would be: browse an app market, showing a list of WSGIpython apps select an app and choose "install" the app would be downloaded from a remote server to the user's server the http server would then have to be configured to start serving that application from the app's id, ex. a blog app with an id of "blog" at "/blog/", so all requests below /blog/ would be seen as root by the blog application. Any suggestions on how to set something like this up? Holler if my flow of consciousness lost you ;)

  • WM_SYSCOMMAND oddities

    - by Andreas Rejbrand
    An application recieves the WM_SYSCOMMAND message when the user selects a menu item command on the system menu, and so wParam can be SC_CLOSE, SC_CONTEXTHELP, SC_MAXIMIZE, SC_MINIMIZE, SC_RESTORE etc. That's logical. But one can also send the WM_SYSCOMMAND message to send commands to the Windows Shell. For instance, one can display the start menu (SC_TASKLIST), activate the screen saver (SC_SCREENSAVE), and turn off the monitor (SC_MONITORPOWER). This does not make sense, does it? What does this have to do with the application's system menu? This is more of a "system command", i.e. more of a completely other interpretation of the name "WM_SYSCOMMAND" of the message. It's like the message is used to send command requests to the system. Why is this message used for two seemingly entirely different things, and what thing does the name "SYSCOMMAND" refer to (command on the system menu, or command of the operating system)?
