  • Is it possible to drag an HTML element out of another element and trigger a change with jQuery?

    - by blackrobot
    I have a container element that you can drag objects around in. I want it it so that if you drag an element out of the container (when the mouse crosses the border of the containing div) the element you're dragging to change. How do I arrange this? $("#container img").draggable({ helper: 'clone', zIndex: 100 }); Once the image crosses the bounds of "#container" I should be able to change the image source.

  • Good starting point to learn regular expressions.

    - by Jeremy Rudd
    I'm good at learning new languages and platforms, though whenever I try to learn Reg Ex I cannot make sense of it. I once even used the Regular Expression Designer to try and put some together. What's a good starting point to understanding what looks like the only rocket-science programming language in the world? Links to articles, books or anything else that could help me get my grounding would be appreciated.

  • Symmetric Encryption: Performance Questions

    - by cam
    Does the performance of a symmetric encryption algorithm depend on the amount of data being encrypted? Suppose I have about 1000 bytes I need to send over the network rapidly, is it better to encrypt 50 bytes of data 20 times, or 1000 bytes at once? Which will be faster? Does it depend on the algorithm used? If so, what's the highest performing, most secure algorithm for amounts of data under 512 bytes?

  • Code generator tool to generate a property and backing field

    - by MattSlay
    I'm working in VS2008 and C#, and I'm looking for a (free) code generator tool to generate a property with getter and setter, as well as the backing private field to go with. The template thingy in VS does not make the field to go with it. Just looking for something a little bit better. I once saw a web site where you could build this code, then cust-and-paste it from the web page to your code.

  • Android Test testPreconditions

    - by user1184113
    In Android developers I've seen that testPreconditions() method is supposed to be launch before all tests. But in my app test, it's acting like a normal test. It does not run before all tests. Is there something wrong ? Here is the description about testPreconditions() from android developer : "A preconditions test checks the initial application conditions prior to executing other tests. It's similar to setUp(), but with less overhead, since it only runs once."

  • Making a WCF call with AJAX

    - by DotnetDude
    Is it required to use a RESTful service to be able to make a ajax call to a wcf service (for example: by using WebInvoke attribute on Operation contracts) Once a service is made RESTful by adding a webHttp binding on the service host, can the host have other endpoints as well? (wsHttp or netTcp) Is it required that the aspNetCompatibilityEnabled be set to true for a service that has webHttp binding (and can this setting coexist for other endpoints) I understand I can use both JQuery and ScriptManager for making WCF calls on the client. Why should I use one over the other?

  • iAd banner gives warning when pushed off screen by navController

    - by James Dunay
    I have a iAd that seems to be correctly displaying but when push a new view controller into the view i get a warning from the iAd that says it has been: WARNING A banner view (0x490fd0) has an ad but may be obscured. This message is only printed once per banner view. But the ad still runs fine so should i pay attention to this? I just tried adding self.adBannerView = nil; [adBannerView release];` just before i push the viewController but i still get that error

  • What is the most annoying ignorance you've had in programming?

    - by someone
    What was an annoying programming situation you had that a little bit of knowledge could've solved? That after you struggled with something tedious/annoying/frustrating, you learned one small thing and said "oh, I could've done that?!"? My example - I once suffered through an entire tedious semester of HTML in Notepad... only to discover Notepad++ (and DreamWeaver, IDEs, etc.) a couple of days after submitting the final project.

  • Python: concatenate generator and item

    - by TarGz
    I have a generator (numbers) and a value (number). I would like to iterate over these as if they were one sequence: i for i in tuple(my_generator) + (my_value,) The problem is, as far as I undestand, this creates 3 tuples only to immediately discard them and also copies items in "my_generator" once. Better approch would be: def con(seq, item): for i in seq: yield seq yield item i for i in con(my_generator, my_value) But I was wondering whether it is possible to do it without that function definition

  • If I Design a CPU Can I Get it Realized in Hardware at a Reasonable Cost?

    - by mudge
    I want to design a CPU and possibly memory and other hardware. I could do this with a hardware description language. Once I do this is it possible for me to send my designs to a manufacturer who will realize the design in hardware and send back to me the CPU(s) ? Can it be done at a reasonable cost? I want to design and make my own computer system and actually have it realized in hardware.

  • Percentage function for a group based on another group.

    - by Jeff O
    I have two grouping levels in a report. Group A can have a Percentage() of the entire report and so can Group B, but I would like to know the Percentage() of Group A of Group B. Even if I code it, it seems like once the inner and outer groups have created their footers, I can't go back to to the inner group and set it's value. Example: Group A Total 50 Group A percentage of Report Total = 33% Group A Percentage of Group B Total = 33% but I want 50% Group B Total 100 Group B Percentage of Report Total = 66% Report Total 150

  • prompt to reboot computer after installation completed

    - by Ashwin
    I am currently adding a deployment project to my C# solution which installs a windows service and I have been trying to find a property that will make the installer prompt the user to reboot the system once installation has completed. I would prefer to simply set a property rather than create a small application that I run at the end of the install.

  • PCRE (recursive) pattern that matches a string containing a correctly parenthesized substring. Why d

    - by Anton N. Petrov
    Well, there are other ways (hmmm... or rather working ways) to do it, but the question is why does this one fail? / \A # start of the string ( # group 1 (?: # group 2 [^()]* # something other than parentheses (greedy) | # or \( (?1) \) # parenthesized group 1 ) # -group 2 + # at least once (greedy) ) # -group 1 \Z # end of the string /x Fails to match a string with nested parentheses: "(())"

  • SSIS: Way to handle hot folder items in parallel?

    - by Dr. Zim
    We have eight Xeon (i7) cores and 16 gig of RAM on our SSIS box. We have about 200 image files we want to convert using a command line utility every day. Currently the process is using Adobe Photoshop and droplets (very manual, taking upwards of two hours a day) Using SSIS hot folders, is there a way to execute up to eight conversions at once? Is there any way to tell a process completed or execute code upon it's completion?

  • Force Word Normal View

    - by Jared
    I am creating an HTML document which we are then pushing out to MS Word using a "application/msword" content type. This works so far except that the files open in Word with Web View. Once Normal View is selected all works fine. Is there any way to force Word to open with Normal View instead of Web View?
