  • Getting Active Session counts with JMX (Java Management Extensions) API

    - by bLee
    I'm trying to use JMX API to get active session counts for a web application. Is it possible to use JMX API to get this kind of information? If yes, how reliable would it be? Any example code on how to get this done? I've been reading JMX tutorial and documentation, but they are giving me the overview of what the technology is. I just can't pinpoint to what I need, yet.

  • Checking existence of file types via extensions bash.

    - by Tommy
    Hi, I need to test if various file types exist in a directory. I've tried $ [ -f *.$fileext] where fileext is the file extension but that does not seem to work. Both of these methods work function checkext() { fileext=$1 ls *.$fileext>/dev/null 2>&1 if [ $? -eq 0 ] then echo "We have $fileext files!" else echo "We don't have any $fileext files!" fi } and function checkext2() { extention=$1 filescheck=(`ls *.$1`) len=${#filescheck[*]} if [ $len -gt 0 ] then echo "We have $extention files!" else if [ $len -eq 0 ] then echo "We don't have any $extention files!" else echo "Error" fi fi } The second method is less tidy as any ls error is shown so I prefer method 1. Could people please suggest any improvements, more elegant solutions e.t.c

  • Nullreferenceexception when adding a GData.Extensions.Reminder to Reminders

    - by user283182
    Hello again, I think the title says it all. I'm using Reminder fifteenMinReminder = new Reminder(); fifteenMinReminder.Minutes = 15; fifteenMinReminder.Method = Reminder.ReminderMethod.email; entry.Reminders.Add(fifteenMinReminder); on a brand new entry (where Reminder and Reminders are Nothing), but I cannot add a reminder using the above code (taken straight from the Google Docs), or set the entry.Reminder to fifteenMinReminder directly either. What am I doing wrong? I've had no trouble .adding When and Where's to the entry, but the Reminder doesn't want to follow the same pattern. Any ideas?

  • How to use visibilitychange event on Firefox Extensions

    - by Tom S.
    I'm trying to learn how to make a firefox extension. I want to create a toolbar that only shows up on a specific page. I can make the toolbar appear, but then it should become hidden when I open or switch to a new tab, or close the tab with that specific page. I don't understand how to make the visibilitychange event work though, no matter what I try nothing happens. window.addEventListener("load", function load(event){ window.removeEventListener("load", load, false); myExtension.init(); },false); var myExtension = { init: function (aEvent) { gBrowser.addEventListener("DOMContentLoaded", this.showToolbar, false); }, showToolbar: function(aEvent) { var doc = aEvent.originalTarget; if(doc.location.href=="http://www.google.ca/"){ eToolbar=document.getElementById("nav-toolbar"); eToolbar.hidden=false; //no matter how I change this line below it never does anything gBrowser.addEventListener("mozvisibilitychange", this.toggleToolbar, false); } }, toggleToolbar: function(aEvent) { eToolbar=document.getElementById("nav-toolbar"); if(document["mozVisibilityState"]=="mozHidden"){ eToolbar.hidden=true; } else { eToolbar.hidden=false; } } }

  • Safari extensions: style of selectbox like safari's bookmark folders

    - by janoliver
    Hey guys, I'm developing an extension for Safari 5 at the moment. In my extension, I use an additional toolbar, with selectboxes in it. Now, it would be great to style these like the folders in the bookmarks toolbar look. I know that it would be possible to replace my select with a completely styleable ul-list or somethin like that, but maybe there is a simpler solution. Doesn't apple provide extra tools to imitate their look? Best regards and thanks for help, Jan

  • OSX / Kernel extensions: problem locating a driver (that extends IOSCSIPeripheralDeviceType00)

    - by LG
    Hi, I'm implementing a driver that extends IOSCSIPeripheralDeviceType00 as I need to send custom SCSI commands to a device. I'm following the VendorSpecificType00 and SimpleUserClient examples and http://wagerlabs.com/writing-a-mac-osx-usb-device-driver-that-impl as an example. I built my kernel extension and it loads fine with kextload and it shows up in kextstat. The problem is that I can't locate it in my user space code. Here's the important (I think) part of: my driver code: #define super IOSCSIPeripheralDeviceType00 OSDefineMetaClassAndStructors(com_mycompany_driver_Foo, IOSCSIPeripheralDeviceType00) my user client code: #define super IOUserClient OSDefineMetaClassAndStructors(com_mycompany_driver_FooUserClient, IOUserClient) the plist: CFBundleIdentifier -> com.mycompany.driver.Foo IOCLass -> com_mycompany_driver_Foo IOUserClientClass -> com_mycompany_driver_FooUserClient IOProviderClass -> IOSCSIPeripheralDeviceNub Here's how I try to locate the driver in my user space code (similar to SimpleUserClient): dictRef = IOServiceMatching("com_mycompany_driver_Foo"); kernResult = IOServiceGetMatchingServices(kIOMasterPortDefault, dictRef, &iterator); When I execute the code, iterator is 0. I noticed that in the VendorSpecificType00 code, the localization of the driver is done differently: dictRef = IOServiceMatching("IOBlockStorageServices"); kr = IOServiceGetMatchingServices(kIOMasterPortDefault, dictRef, &iter); while ((service = IOIteratorNext(iter))) { io_registry_entry_t parent; kr = IORegistryEntryGetParentEntry(service, kIOServicePlane, &parent); ... // We're only interested in the parent object if it's our driver class. if (IOObjectConformsTo(parent, "com_apple_dts_driver_VendorSpecificType00")) { I tried doing that but it didn't work either. Thanks for reading and your help, -L

  • Chrome extensions: Content script (jQuery) in Youtube does not work properly

    - by Fabian
    I have this: $(document).ready(function() { $("button.yt-uix-expander-arrow").attr("id", "yt-uix-expander-arrow"); $("#yt-uix-expander-arrow").mouseover(function() { alert("Hello"); }); }); injected into Youtube. Using right click inspect element, the <button class="yt-uix-expander-arrow"> has a id="yt-uix-expander-arrow" attribute successfully added to it. However the mouseover event does not trigger. However if I were to change $("#yt-uix-expander-arrow").mouseover() to $(".yt-uix-expander-arrow").mouseover() it works. That's very unusual, because the #yt-uix-expander-arrow id has already been added to the button element. I tested it out on Facebook, adding a id to a class and doing a mouseover() event on the ID and it works. Any idea?

  • Listing down stored records localStorage | Google Chrome Extensions

    - by Jamie
    How do I get to list down the stored records in the for loop? Basically I want it to list down the records like this: '<div id="record_' + number + '">' + localstorage value + '</div>' The number in the class should add 1 every record, e.g. 1, 2, 3, 4 every record it lists down, and so on. The localstorage value should show the localStorage[] but the problem is, the localStorage name has the same, e.g. (clicks on button) it will save the value of the URL into a localStorage I then open the application and shows the window.html inside there is list of stored records by using this: '<div id="record_' + number + '">' + localstorage value + '</div>' INCLUDING the record number to add per record 1, 2, 3, etc... like this: <div id="record_1">localstorage value</div> <div id="record_2">localstorage value</div> <div id="record_3">localstorage value</div> <div id="record_4">localstorage value</div> <div id="record_5">localstorage value</div> <div id="record_6">localstorage value</div> etc...

  • Website --> Add Reference also creates files with pdb extensions

    - by SourceC
    Hello, Q1 Any assemblies stored in Bin directory will automatically be referenced by web application. We can add assembly reference via Website -- Add Reference or simply by copying dll into Bin folder. But I noticed that when we add reference via Website -- Add Reference, that additional files with .pdb extension are placed inside Bin. If these files are also needed, then why does reference still work even if we only place referenced dll into Bin, but not pdb files Q2 It appears that if you add a new item to web project, this class will automatically be added to project list and we can reference it from all pages in this project. So are all files added to project list automatically being referenced ? thanx EDIT: On your second question, you are adding a public class to a namespace so will be visible to other classes in that project and in that namespace. I don’t know much about assemblies, but I’d assume the reason why item( class ) added to the project is visible to other classes in that project is for the simple fact that in web project all classes get compiled into single assembly and for the fact that public classes contained in the same assembly are always visible to each other? much appreciated

  • MySQL GIS and Spatial Extensions - how to map regions and query against them

    - by chibineku
    I am trying to make a smartphone app which will return a list of users within a certain proximity, say 100m. It's easy to get the coordinates of my BlackBerry and write them to a database, but in order to return a list of other users within 100m, I need to pull every other record from the database and compare the distance between the two points, checking to see if it's within range, before outputting that user's information. This is going to be time consuming if there are many users involved. So I would like to map areas (countries, cities, I'm not yet sure of the resolution I'll need) so that I can first target a smaller subset of all users. This will save on processing time. I have read the basics of GIS and spatial querying on the mysql website but to be honest the query is over my head and I hate copying and pasting code without understanding it. Plus it only checks for proximity - I want to first check if a coordinate falls within a certain area. Does anyone have any experience of such matters and feel like giving me some pointers? Resources such as any preexisting databases of points describing countries as polygons would be really helpful too. Many thanks to anyone who takes the time :)

  • How to unit test chrome extensions?

    - by swampsjohn
    Is there a good way to do this? I'm writing an extension that interacts with a website as a content script and saves data using localstorage. Are there any tools, frameworks, etc. that I can use to test this behavior? I realize there are some generic tools for testing javascript, but are those sufficiently power to test an extension?

  • ruby c extensions: character values over 127

    - by Adrian
    I am trying to make a C extension for Ruby that includes a method returning a string, which will sometimes have character values that need to be in an unsigned char. In http://github.com/shyouhei/ruby/blob/trunk/README.EXT, all of the functions listed for turning C strings into Ruby strings take signed chars. So I couldn't do this: unsigned char bytes[] = {0xf0, 0xf1, 0xf2}; return rb_str_new(bytes, 3); How could I make a method that returns these types of strings? In other words, how would I make a C extension with a method returning "\xff"?

  • Managing logs/warnings in Python extensions

    - by Dimitri Tcaciuc
    TL;DR version: What do you use for configurable (and preferably captured) logging inside your C++ bits in a Python project? Details follow. Say you have a a few compiled .so modules that may need to do some error checking and warn user of (partially) incorrect data. Currently I'm having a pretty simplistic setup where I'm using logging framework from Python code and log4cxx library from C/C++. log4cxx log level is defined in a file (log4cxx.properties) and is currently fixed and I'm thinking how to make it more flexible. Couple of choices that I see: One way to control it would be to have a module-wide configuration call. # foo/__init__.py import sys from _foo import import bar, baz, configure_log configure_log(sys.stdout, WARNING) # tests/test_foo.py def test_foo(): # Maybe a custom context to change the logfile for # the module and restore it at the end. with CaptureLog(foo) as log: assert foo.bar() == 5 assert log.read() == "124.24 - foo - INFO - Bar returning 5" Have every compiled function that does logging accept optional log parameters. # foo.c int bar(PyObject* x, PyObject* logfile, PyObject* loglevel) { LoggerPtr logger = default_logger("foo"); if (logfile != Py_None) logger = file_logger(logfile, loglevel); ... } # tests/test_foo.py def test_foo(): with TemporaryFile() as logfile: assert foo.bar(logfile=logfile, loglevel=DEBUG) == 5 assert logfile.read() == "124.24 - foo - INFO - Bar returning 5" Some other way? Second one seems to be somewhat cleaner, but it requires function signature alteration (or using kwargs and parsing them). First one is.. probably somewhat awkward but sets up entire module in one go and removes logic from each individual function. What are your thoughts on this? I'm all ears to alternative solutions as well. Thanks,

    Can I create a symlink to the local extension from aonther project folder? I have a common local-server and i need to implement same extension on all local project-installations. I tried to put the symlink, but some times i do not get expected output. I get it only after clearing the cache of that perticular project.

  • I'm using the correct content type & Headers so Why is FireFox saving Zip Files without extensions

    - by The_AlienCoder
    Users on my site have the option to download all the photos in an album as a zip file.The Zip file is dynamically created and saved to Response.OutPutStream to be detected as a file download on the user's browser. Here is the Header and Content-type I am outputing context.Response.AddHeader("Content-Disposition", "attachment; filename=Photos.zip"); context.Response.ContentType = "application/x-zip-compressed"; ..Well everything works fine with every browser except FireFox. Although Firefox correctly detects the download as a Zip file, It saves the file without the .zip extension. I thought adding this header context.Response.AddHeader("Content-Disposition", "attachment; filename=Photos.zip"); ..is supposed to force FF to save the extension. I believe I am following the correct protocol so why is FF behaving this way and how do I fix this?

  • .htaccess Redirect Loop, adding multiple .php extensions

    - by Ryan Smith
    I have sort of a small parent/teacher social network set up for my school. I use my .htaccess file to make the links to teacher profiles cleaner and to add a trailing slash to all urls. I get this problem when going to /teachers/teacher-name/ the link (sometimes) redirects to /teachers/teacher-name.php.php.php.php.php.php.php.php... Below is my .htaccess file. Sometimes if I clear my browser cache in Chrome it temporarily fixes it. I can't exactly wright .htaccess syntax, but I'm pretty familiar with it. Any suggestions are appreciated! RewriteEngine on RewriteBase / #remove php ext RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME}\.php -f RewriteRule ^([^/]+)/$ $1.php RewriteRule ^([^/]+)/([^/]+)/$ $1/$2.php #force trailing slash/ RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)([^/])$ /$1$2/ [L,R=301] #other rewrites RewriteRule ^teachers/([^/\.]+)/$ /teachers/profile.php?u=$1 RewriteRule ^teachers/([^/\.]+)/posts/$ /teachers/posts.php?u=$1 RewriteRule ^teachers/([^/\.]+)/posts/([^/\.]+)/$ /teachers/post.php?u=$1&p=$2 RewriteRule ^gallery/([^/\.]+)/$ /gallery/album.php?n=$1 RewriteRule ^gallery/([^/\.]+)/slideshow/$ /gallery/slideshow.php?n=$1 RewriteRule ^gallery/([^/\.]+)/([^/\.]+)/([^/\.]+)/$ /gallery/photo.php?a=$1&p=$2&e=$3 EDIT:I have attached a screenshot of exactly what I'm talking about.

  • Integer Extensions - 1st, 2nd, 3rd etc [closed]

    - by David Schiefer
    Possible Duplicate: NSNumberFormatter and ‘th’ ‘st’ ‘nd’ ‘rd’ (ordinal) number endings Hello, I'm building an application that downloads player ranks and displays them. So say for example, you're 3rd out of all the players, I inserted a condition that will display it as 3rd, not 3th and i did the same for 2nd and 1st. When getting to higher ranks though, such as 2883rd, it'll display 2883th (for obvious reasons) My question is, how can I get it to reformat the number to XXX1st, XXX2nd, XXX3rd etc? To show what I mean, here's how I format my number to add a "rd" if it's 3 if ([[container stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]] isEqualToString:@"3"]) { NSString*badge = [NSString stringWithFormat:@"%@rd",[container stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]]; NSString*scoreText = [NSString stringWithFormat:@"ROC Server Rank: %@rd",[container stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]]; profile.badgeValue = badge; rank.text = scoreText; } I can't do this for every number up to 2000 (there are 2000 ranks in total) - what can I do to solve this problem?
