• Guaranteeing the onmouseout event to fire

  - by n3rd

  Hello everybody, I'm currently developing a web application and have run into a little problem. I'm using ExtJS, but I believe this to be a general JS question. When the cursor enters an HTML element, the onmouseover event is fired, when the cursor leaves that element, onmouseout is triggered. So far, so good. Unfortunately, it seems one can't fully rely on this behaviour. Very quick mouse movements can cause the event not to fire (as does repositioning the cursor with a pen tablet, for example). What are the best practices to handle these issues? Do I need to monitor all onmousemove events and manually keep track of where the cursor was last and fire the appropriate onmouseout event myself?

• Batch backup a harddrive without modifying access times C#

  - by johnathan-doena

  I'm trying to write a simple program that will backup my flash drive. I want it to work automatically and silently in the background, and I also want it to be as quick as possible. The thing is, resetting all the access times is useless to me, and something I want to avoid. I know I can read the access times and set them back, but I bet it will fail one day in the future. It would be much simpler to read the files without ever changing it. Also, what is the fastest way to do this? What differences would there be between, say, a flash drive and an external hard drive. I am writing this in C#, as it is the simplest way to do it and it will probably last more generations of Windows..

• Android : How to Remove all capital letters from image filenames before importing into Eclipse

  - by Hubert

  As you know, you can't have capital letters in your image filenames that you use in your Android project (Ressource/Drawables folder). I've got hundreds of small images (GOOG.GIF as an exemple) that I need to import into my project (I usually do a simple drag and drop from a desktop folder into Eclipse). So here's the question : How do I quickly change all the filenames (replace all capital letters to lower case) before importing into my project ? So, GOOG.GIF becomes goog.gif AAPL.GIF becomes aapl.gif etc. Any quick command line solution or another tool to do just that ? Thanks.

• Reallocating memory via "new" in C++

  - by BSchlinker

  Quick question regarding memory management in C++ If I do the following operation: pointer = new char [strlen(someinput_input)+1]; And then perform it again, with perhaps a different result being returned from strlen(someinput_input). Does this result in memory being left allocated from the previous "new" statement? IE, is each new statement receiving another block of HEAP memory from the OS, or is it simply reallocating? Assuming I do a final delete pointer[]; will that deallocate any and all memory that I ever allocated via new to that pointer? Thanks

• Do I need to include all fields in my entity framework model

  - by Jim B

  Quick question for everyone: Do I need to include all the database table fields on my EF model? For example; I've created a sub-model that only deals with tblPayment and associated tables. Now, I need to write a LINQ query to get some information about items. I would typically get this by joining tblPayment to tblInvoice to tblInvoiceItem to finally tblOrderItem. I'm wondering if when I add in those other tables, do I need to include all the fields for tblInvoice and tblInvoiceItem? Ideally; I'd just like to keep the fields I'd need to join on, as that would limit the possibility of my sub-model breaking if other fields on those tables are modified/deleted. Can I do this?

• Why does Net::Twitter complain "HTTP::Message content not bytes"?

  - by Russell C.

  We have been using Perl's Net:Twitter CPAN module (version 3.12) and basic authentication (not OAuth) for almost a year now to syndicate updates from our site to our Twitter account. We just migrated to a new server last week and since the move our updates to Twitter have stopped and the following error is being reported whenever we try to post an update: HTTP::Message content not bytes at /usr/lib/perl5/site_perl/5.8.8/HTTP/Request/Common.pm line 90 Here is the code we're using the update our Twitter account: use Net::Twitter; my $twitter = Net::Twitter->new( traits => [qw/API::REST/], username => $username, password => $password, source => 'twitterfeed' ); my $result = $twitter->update($status); I have no idea what the issue is and was hoping that someone else has run into this issue and can provide a quick solution. Thanks in advance for your help!

• Bootstrap Modal & rails remote

  - by Kevin Brown

  Using this bootstrap modal extension and animate.css for fun, how can I take a make an easy ajax modal using :remote => true to fill in the modal box? Also, how would I use the bootstrap modal default "submit/cancel" buttons to interact with a form that's loaded? I'm looking for a more dynamic solution instead of hard-html-ing every modal into the page or using a bunch of jquery ajax calls for each dialog. I've done a few quick searches, but they've turned up nil for this particular solution.

• Avoid application becoming unresponsive on download

  - by baron

  Hi I have an application which downloads a file from a network location and then displays that files information. It uses WebClient.DownloadFile to achieve this. The problem is, when the user clicks a button to start the download, the application becomes unresponsive until the file has downloaded. This gives the impression the application may have hung. I would like to seek ideas which would avoid this scenario. Though my solution will need to be 'as quick and cheap as possible' I would be interested in hearing about custom loaders that have been built, or some sort of loading symbol / progress bar / sand time clock thingy : ) Thanks for reading.

• Using a singleton database class in functions and multiple scripts(PHP) - best use methods

  - by dscher

  I have a singleton db connection which I get with: $dbConnect = myDatabase::getInstance(); which is easy enough. My question is what is the least rhetorical and legitimate way of using this connection in functions and classes? It seems silly to have to declare the variable global, pass it into every single function, and/or recreate this variable within every function. Is there another answer for this? Obviously I'm a noob and I can work my way around this problem 10 different ways, none of which is really attractive to me. It would be a lot easier if I could have that $dbConnect variable accessible in any function without needing to declare it global or pass it in. I do know I can add the variable to the $_SERVER array...is there something wrong with doing this? It seems somewhat inappropriate to me. Another quick question: Is it bad practice to do this: $result = myDatabase::getInstance()-query($query); from directly within a function?

• Change right-click context menu options in VS2008

  - by Mark Ursino

  When I right-click in my class library, I get some quick options to create things, like an Item from the popup list (New Item...), a User Control, etc. E.g. Now in my web app project, I'd like to be able to get the User Control listed in the right-click menu just like Component and Class, so I don't have to click New Item... then choose it from there. Is there a way to do this in the configuration? I can't seem to figure it out in VS.

• How do I load only a single wordpress post via the url?

  - by Jared

  Hello, We are currently undergoing some reworking of our website - in the meantime, I am looking for a quick a dirty fix. We have wordpress setup, so that no-so-tech-savvy employees can add events, news, etc. However, there are currently sections on our site dedicated to what would be tags in Wordpress. For instance, we have posts in WP with the tag "events." It's easy enough to display all posts with that tag, but I need to do a PHP include on our old site, and only show JUST THE POST. I can use a rss2html tool, but it strips out somethings like necessary tables. So how do Display only a single WP post, without anything else (no menus, settings, no Wp interface) via a URL? I could use a theme that is stripped down (by using something like theme switcher), but I need it to only load that theme once, not be the default theme....

• Send mail from a Windows script

  - by Jörgen Lundberg

  I would like to send mail from a script on a Windows Server 2003 Standard Edition. I think the server setup is pretty much out of the box. The mail server is an Exchange one, and when you're on the internal network you can use plain old SMTP. I have done it from my machine with Perl, but unfortunately Perl is not available on the server. Is there an easy way of doing this from a .bat-file or any other way that doesn't require installing some additional software? Edit: Thanks for the quick replies. The "blat" thingie would probably work fine but with wscript I don't have to use a separate binary. I didn't see PhiLho's post the first time I edited and selected an answer. No need for me to duplicate the code here. Just save the script to a file, say sendmail.vbs, and then call it from the command prompt like so: wscript sendmail.vbs

• Built in raytracing?

  - by acidzombie24

  Relating to this question i was wondering if .NET has any libs (or a function) i can use to detect if one point collides with another. I am not sure what angles i should use but is there some function like this func(point src, rect target, angle, distanceOfVision, listPointOrRectOfWalls) Pretty unlikely but i dont know a formula or how to start. Its a quick and dirty prototype. I am thinking of writing the func about but dropping angle and just make line of sight a rectangle and check if any points is between src and target.

• How to provide animation when calling another activity in Android?

  - by sunil

  Hi, I have two Activities A and B. I want to have the shrink Animation when Activity A calls B and maximize animation when Activity B calls A. I don't need the animation xml files for this. When we call another Activity in Android it gives its default animation and then it calls shrink animation. What I want is that the default animation should not occur and the animation that I want should occur. Can we actually give the animation when calling another Activity? Hope to get a quick response.

• Where is a Web Development Career fueled by Passion? [closed]

  - by JMC Creative

  Quick Background Since learning basic html 5 years ago, I've become completely obsessed with the technology, the logic, and the thrill of solving problems involved with building websites. I am still stuck at a thoroughly non-programming type job, but would really like to move into the field of web programming/design. I have no educational background in the field (was trained as a fine artist and tutor), but in the past few years have progressed fully self-taught (and self-motivated) from html to css to php, mysql, jquery, and am now building rich web applications. The Question How can I prove to a company that even though I have no education, I have a passion to learn whatever is thrown my way? ...That essentially I would come at every issue with not only knowledge, but with a passionate desire to solve it, whether that means tackling a new language or debugging code for hours at a time? p.s. Sorry for the stupid title.

• Python how to handle # in a dictionary

  - by Jack

  I've got some json from last.fm's api which I've serialised into a dictionary using simplejson. A quick example of the basic structure is below. { "artist": "similar": { "artist": { "name": "Blah", "image": {"#text":"URLHERE","size": "small"} "image": {"#text":"URLHERE","size": "medium"} "image": {"#text":"URLHERE","size": "large"} } } } Any ideas how I can access the image urls of various different sizes. My attempts at accessing the #text variable don't seem to work because python doesn't appear to like #'s in the names. And any ideas how I can easily get the url for the depending on the size? Thanks, Jack

• Why is the dictionary debug visualizer less useful in Visual Studio 2010 for Silverlight debugging?

  - by Kevin

  I was debugging in Visual Studio 2010, which we just installed and trying to look at a dictionary in the quick watch window. I see Keys and Values, but drilling into those shows the Count and Non-Public members, Non-Public members continues the trail and I never see the values in the dictionary. I can run test.Take(10) and see the values, but why should I have to do that. I don't have VS 2008 installed anymore to compare, but it seems that I could debug a dictionary much easier. Why is it this way now? Is it just a setting I set somehow on my machine? Test code: Dictionary<string, string> test = new Dictionary<string, string>(); test.Add("a", "b"); EDIT: I've just tried the same debug in a Console app and it works as expected. The other project is a Silverlight 4 application, why are they different? Console Debug Screen Shot Silverlight 4 Debug Screen Shot:

• Question about finding third party website APIs.

  - by Abe Miessler

  I have a client that works with several well established 3rd party sites to sell his product (in this case hotel rooms, but the question is more general). Every time he gets a reservation he has to go to each site and manually make changes. I've done a quick search to see if there are APIs or any developer resources for these sites but have come up with nothing. I've emailed his contacts for each site but have yet to receive a response. I don't have a lot of experience working with third party sites like this but in the past when I've looked for APIs I usually come up empty handed. Are these types of APIs rare or am I just looking in the wrong places? It seems like an obvious thing to have for a company that has an affiliate program. Any suggestions on where to look for APIs or am I at the mercy of my "contact"?

• Solr Vs. Sphinx in a Ruby project

  - by Robert Ross

  I have a project that is being written on top of the Grape API framework in ruby. (https://github.com/intridea/grape) The problem I'm having is that Thinking-Sphinx vs. Sunspot (Gems used to interface with each search index) have worlds different benchmarks. View the Benchmark Here We're trying to develop something that is quick and easy to deploy (Solr needs Java). The issues we see right now is mainly that Solr is slower through Sunspot gem and Sphinx is faster through Thinking-Sphinx because Solr is HTTP REST calls where Sphinx is sockets. Anyone have any experience in either and can explain pitfalls / bonuses? Note: Needs to be deployable to Rails AND non-rails apps (Hence Sunspot). Thanks!

• How do you override an existing html form to use jquery to post the form?

  - by Chris

  I have a simple form that I am currently posting back to the server to update a nickname. What jquery code do I add (without changing the form) so that the page will not refresh, but instead jquery will post the form in the background and then pop up an alert message containing the reply back from the server? <form method="post" action="http://www.myserver.com/update_nickname" name="input"> Quick form to test update_nickname:<br> New nickname:<input type="text" value="BigJoe" name="newNickname"><br> <input type="submit" value="Submit"> </form> <script src="jquery-1.4.2.min.js" type="text/javascript"> </script>

• Pros and cons of keeping metadata in image thumbnails

  - by SODA

  I am working on optimizing site load speed for a few moderately high traffic sites. Some quick observations show that creating 40 picture thumbnails (e.g. 138x138 JPG @75% quality) results in 700 Kb total size with embedded metadata and 258 Kb with stripped metadata. Which means that roughly 60% of image size is metadata. So what would be pros and cons of removing metadata from thumbnails? Are there any regulations, e.g. you must keep author info / copyright info in the images? Any insights would be appreciated.

• Why should pop() take an argument?

  - by Stephano

  Quick background I'm a Java developer who's been playing around with C++ in my free/bored time. Preface In C++, you often see pop taking an argument by reference: void pop(Item& removed); I understand that it is nice to "fill in" the parameter with what you removed. That totally makes sense to me. This way, the person who asked to remove the top item can have a look at what was removed. However, if I were to do this in Java, I'd do something like this: Item pop() throws StackException; This way, after the pop we return either: NULL as a result, an Item, or an exception would be thrown. My C++ text book shows me the example above, but I see plenty of stack implimentations taking no arguments (stl stack for example). The Qustion How should one implement the pop function in C++? The Bonus Why?
