  • After 30 seconds, update MYSQL databse

    - by Sam
    Hello everyone! I've been looking around here on SO and Googling, however I can't find anything that fits my description. What I want to do is update the database if the page has not been refreshed after 30 seconds. I want to email a person with the contents of a form {submitted by a different user} (I can do that) IF the person has NOT visited the page (I can do that) within the last 30 seconds. What I've tried to do is make the page that should be visited refresh every 30 seconds, and so I figured if I did something like after 31 seconds, edit the database (so if the refreshed page was not refreshed, the database editing would run). I'm sorry if this sounds complicated, there's probably a better way to do this, but I'm not sure how. The bigger picture is I'm trying to make a 'on-duty' sort of thing, so that if the person is not actively looking at the page, they will get emailed with whatever the contents of the form is. The page will contain a table of all the entered form results.

  • SharePoint 2010 - Change table row /cell hover effect

    - by Sam
    In SharePoint 2010 when you hover over a column heading (i.e. to sort) in a list table, you get a hover effect, how can you supress / change this? I can see it uses OnChildColumn(this), so is there a way to modify this - either preventing the effect (e.g. when sorting can't be done on a column), or using a different background image? Also want to do the same when you hover over a cell in any of the list table's contents.

  • How do I check that an entity is unreferenced in JPA?

    - by Martin
    I have the following model @Entity class Element { @Id int id; @Version int version; @ManyToOne Type type; } @Entity class Type { @Id int id; @Version int version; @OneToMany(mappedBy="type") Collection<Element> elements; @Basic(optional=false) boolean disabled; } and would like to allow Type.disabled = true only if Type.elements is empty. Is there a way to do it atomically? I would like to prevent an insertion of an Element in a transaction while the corresponding Type is being disabled by an other transaction.

  • What is the result of this SQL query?

    - by Martin
    I'm working on a mock exam paper at the moment, however I have no set of correct answers and I'm not sure what the correct answer of this SQL query is. Given a table: foo, bar a , 1 b , 3 a , 2 c , 1 and the query: SELECT foo, sum(bar) FROM table GROUP BY foo The two ways I can see this going are either: a 3 a 3 b 3 c 1 or a 3 b 3 c 1 Thanks.

  • Comparison of IPEndPoint objects not working

    - by Martin Mizzell
    I have an IPEndPoint a and b, whose IPAddress and Port are exactly the same, but the == operator is on the IPEndPoint not returning true. To make things even stranger, I tried to circumvent the problem by simply comparing the IPAddress and Port individually and it is STILL not returning true. Has anyone encountered this before? If so, I am all ears to performant solutions. We have collections of as many as 10k IPEndPoints and are querying into them via LINQ (PLINQ pretty soon).

  • Where to put the star in C and C++ pointer notation

    - by Martin Kristiansen
    For some time the following has been annoing me, where should I put the star in my pointer notation. int *var; // 1 and int* var; // 2 obviously do the same thing, and both notations are correct, but I find that most literature and code I look at use the 1th notation. wouldn't it be more 'correct' to use the 2th notation, separating the type and the variable name by a whitespace, rather than mixing the type and variable tokens?

  • Should repeated use of the camera crash an app?

    - by Sam
    I have an app that builds a slideshow from user images. They can grab from their library or take a picture. I have found that repeated use of grabbing an image from the library is fine. But repeated use of taking a picture causes erratic behavior. I have been getting crashes but mostly what happens seems to be a reloading of the view after "didFinishPickingMediaWithInfo", which messes things up. I have no leaks and it seems to be releasing properly after each picture is taken. I am resizing the image and saving it in a data base. Is anyone else running into this situation? Was the camera not designed to be called this often?

  • Call c++ function pointer from c#

    - by Sam
    Is it possible to call a c(++) static function pointer like this typedef int (*MyCppFunc)(void* SomeObject); from c#? void CallFromCSharp(MyCppFunc funcptr, IntPtr param) { funcptr(param); } I need to be able to callback from c# into some old c++ classes. C++ is managed, but the classes are not ref classes (yet). So far I got no idea how to call a c++ function pointer from c#, is it possible?

  • Imposing email limits on web page

    - by Martin
    To avoid spammers, what's a good strategy for imposing limits on users when sending email from our site? A count limit per day on individual IPs? Sender emails? Domains? In general terms, but recommended figures will also be helpful. Our users can send emails through our web page. They can register and log in but are also allowed to do this without logging in, but with a captcha and with a field for the senders email. Certainly, there is a header, "The user has sent you the following message.", limiting the use for spammers, so perhaps it's not a big problem. Any comments on what I'm doing will be greatly appreciated.

  • Magento - Using alternative "reviews count" on category list page

    - by Sam
    Hi All I noticed that on the category list page, the number of reviews (pulled from frontend/base/default/template/review/helper/summary_short.phtml) lists the full amount of reviews for an item, not the amount available to the store view you’re on. So, for example (using the sample data) the Samsung MM-A900M Ace has 5 reviews - however, when you click that link and are taken to the reviews page, it actually just has 2 (as only 2 are available to the English view). But on the reviews page, the review count is correct and says 2 reviews (this time pulled from frontend/base/default/template/review/product/view/count.phtml). Is there any way to use this review count on the category list?

  • SQL SERVER Spatial Data

    - by Sam
    Hi All, I am struggeling finding an effectient way to find a distance between a Point that interetcts a polygon and the border of that polygon. I was able to use the STDistance comparing the point to every point that made up the polygon but that is taking a lot of time. Using SPatial indexed wasnt much helpful because the STDistance is not part of any constraint and even when I did put the constraint, the index didnt help much. I appreciate any feedback. Thanks.
