• How to call javascript function when url variable is sent

  - by mattlarkin

  Hello, heres basically what I need to get done. I have a jsp page which allows me to add/modify/delete an item. The items are stored in a database which I have controller classes to access(dont worry bout that part) When an item gets selected and deleted the id of the item gets sent to the controller to be processed. The item will not always be deleted if their is a foreign key constraint so I send either a delete=true or delete=false through url back to the jsp page. I would like to have it so a javascript function gets called displaying an alert saying the item was deleted or the item was not deleted. can someone please tell me the best way to do this? thank you

• The best practice to setup hierarchy data

  - by eski

  I'm trying to figure out the best practice to setup hierarchy data that i take from a database into some contoller that would show the hierachy. Basicly this would look like a normal tree but when you press the items that are under "chapters" you get a link to another page. I have these tables and this is the way they are connected Period Courses Subjects Chapters I select Period from a DropDownBox and then i want all the courses in that period to line up. Under each course would be the subject and under them are the chapers, typical hierarchy. The tables are linked together with refrences to each other in linear way. I have tried to use treeview to show this, but dont understand how to do it. I though i could use <ul><il> tags and do it at runtime. Reapeter or datalist, possible ? Is it better to do this with databinding in XAML or in code ?

• ANY material writen in/for DELPHI around the graphics topic?

  - by José Eduardo

  Does anyone knows ANY material writen in/for DELPHI around the graphics topic? Planning to build a software for medical imaging processing . Thinking in 3D UI to absorve the power of nvidias GTX graphics card, and some real-time 2D processing integrated with high-end scanners. Please dont take this as a "rant" but, we have zillions of C++ books writen about that kind of topic and nothing for pascal/delphi. If you have some experience could you comment about that? Is it better to learn c++, to have access to that material? Can i go with delphi? I have experience with delphi, but none with graphics... And i have a deadline... Thanks.

• Best method to print using wpf 4

  - by user293545

  Howdy, I need to be able to print from my wpf application. I am just trying to print a transaction receipt. I have found that using PrintDialog pDialog = new PrintDialog(); pDialog.PrintVisual(new Receipt("transaction name","my store"), "documentTitle"); Does the trick very nicely. "Receipt() is a usercontrol that renders out the transaction details. How are you meant to do this? is this the correct way? what do I do if I dont know the printer that is going to be used? should I make the usercontrol only as wide as a thermal receipt printer? Any suggestions would be great!

  i have a style : .window .div { border:medium solid #000000; height:150px; background-color: #0099FF; } and then i have another style: #NewDiv { font:Arial, Helvetica, sans-serif; font-size: 24px; height: 20px; border-bottom-width: medium; border-bottom-style: solid; border-bottom-color: #000000; } I need to put a #NewDiv div tag inside of window .div, BUT... #NewDiv must retain its own styling while sitting inside of window .div div tags. How do I do this? Currently when I try, #NewDiv takes on the same styling as window .div when i place it inside of it and i dont want that at all. Any suggestions?

• c# How to make linq master detail query for 0..n relationship?

  - by JK

  Given a classic DB structure of Orders has zero or more OrderLines and OrderLine has exactly one Product, how do I write a linq query to express this? The output would be OrderNumber - OrderLine - Product Name Order-1 null null // (this order has no lines) Order-2 1 Red widget I tried this query but is not getting the orders with no lines var model = (from po in Orders from line in po.OrderLines select new { OrderNumber = po.Id, OrderLine = line.LineNumber, ProductName = line.Product.ProductDescription, } ) I think that the 2nd from is limiting the query to only those that have OrderLines, but I dont know another way to express it. LINQ is very non-obvious if you ask me!

• JPA @version - can it be used to calcualate version of a table entry

  - by OpenSource

  Hi, Please consider the following table (created using a corresponding entity) request ------- id requestor type version items 1 a t1 1 5 2 a t1 2 3 3 b t1 1 2 4 a t2 1 4 5 a t1 3 9 The above is what I want to achieve. The version field is a calculated field others are user provided. Basically the request's version needs to be calculated based on the combination of requestor and the type. The first occurance with a given combination will have a version 1 then version 2 and so on. I tried various things using @version on a different entity with just the three columns and joining the two entities using ManytoOne etc but I'm not able to get to the desired outcome. I dont want to confuse you with the things I tried. Since the objective is simple there should be an easier way I suppose? Can you please help? - any help greatly appreciated! thanks in advance

• .htaccess cross browser

  - by lordsharp

  Hi, Im trying to load a custom error document for a 404 error using a .htaccess file on a linux server, the page gets the current page URL then redirects to another site (which is retrieved from a db) based on an id it retrieved from the URL. The current error documents are stored here: /error_docs/ - i dont have permission to upload anything other than the HTML files that are already in there /HTTPDocs/301redir.php is the site root where the .htaccess file is. i have used the following to load the 301redir.php page as the error doc, which works in FF but no other browsers. ErrorDocument 404 /310redir.php using .htaccess is my only real option for changing this, is there a way to get around this issue and make it work across all browsers?

  Hi all I dont know if its a django bug or a feature but i have a strange ORM behaviour with MySQL. class Status(models.Model): name = models.CharField(max_length = 50) class Article(models.Model) status = models.ForeignKey(status, blank = True, null=True) filters = Q(status__in =[0, 1,2] ) | Q(status=None) items = Article.objects.filter(filters) this returns Article items but some have other status than requested [0,1,2,None] looking at the sql query : SELECT [..] FROM `app_article` LEFT OUTER JOIN `app_status` ON (`app_article`.`status_id` = `app_status`.`id`) WHERE (`app_article`.`status_id` IN (1, 2) OR `app_status`.`id` IS NULL) ORDER BY [...] the OR app_status.id IS NULL part seems to be the cause. if i change it to OR app_article.status_id IS NULL it works correctly. How to deal with this ? Thanx.

• C++ how can I refactor this?

  - by ShaChris23

  I have the code below in my test code in many places: // // Make a function call while expecting an exception should be thrown // bool exceptionThrown = false; try { expectNotEqual(someData, anotherData, methodName); } catch(std::logic_error&) { exceptionThrown = true; } if(!exceptionThrown) throw std::logic_error(methodName+"exception not thrown"); It would be nice (more readable, concise) if I could encapsulate all that, and do something like: exceptionShouldBeThrown(expectNotEqual(someData, anotherData, methodName)); I dont want to use macro ...does anyone know how I could achieve the one-liner above with C++?

• PHP and C# communication with Encrypt/Decrypt

  - by SilentWarrior

  Hello, I have been searching and cant find a consistent solution to my problem : I want to encrypt something in C# and decrypt it in PHP but also be able to encrypt in PHP and decrypt in C#, using the same key on both ends. All the solutions I found dont seem to work both ways, most of them only work on one language and then fail on the other, either by decrypting wrong or by blowing up the offsets. I would like to use TripleDES but it isnt a requirement, just want something relatively strong for plain text communication (will either use JSON or just plain key-value pairs for complex stuff). Thanks in advance PS: http://pastie.org/643106 this is what I have been testing with.
