  • EF Linq Product Sum when no records returned

    - by user1622713
    I’ve seen variations of this question all over the place but none of the answers work for me. Most of them are just trying to sum a single column too – nothing more complex such as the sum of a product as below: public double Total { get { return _Context.Sales.Where(t => t.Quantity > 0) .DefaultIfEmpty() .Sum(t => t.Quantity * t.Price); } } If no rows are returned I want to return zero. However if no rows are returned the .Sum() fails. There are various options of trying to insert Convert.ToDouble and using null coalesce operators, but they all still gave me errors. I’m sure I am missing a simple way to do this – any help greatly appreciated after too long banging head against google brick wall!

  • Creating an array from a MySQL table

    - by Rob
    I'm trying to create an array to use for a curl_multi_exec, but I can't seem to create the array properly. Here is my code: $SQL = mysql_query("SELECT url FROM urls") or die(mysql_error()); //Query the shell table while($resultSet = mysql_fetch_array($SQL)){ $urls[]=$resultSet; } echo $urls; //Test that the array works But when I run this script, all it does is echo "Array" I have no idea what I'm doing wrong, I've checked around google a bit, but can't figure it out. Any insight would be appreciated.

  • Eclipse debug - line: not available

    - by Mike
    I can't seem to find anything on google telling me why this might be and what the resolution is. I'm Stepping through third party code (that I have the source for) and would really like to see the current line being executed... Looking at javac compile flags, I see the -g:none flag. If this flag is set, would this be enough to explain why I'm not able to see line numbers? If so, why would someone do this, are there performance implications? Do I need to recompile the jar myself to attach the missing debug info (if possible)? Thanks!

  • why are javascript functions like this

    - by Kajal
    I am a starter to javascript. I know to write JS userdefined functions. But recently I came across some thing that I can’t recognize. Can anyone explain to me what this is? (function( window, undefined ) { var jQuery = (function() { }); window.jQuery = window.$ = jQuery; })(window); What is the meaning of this? When I Google javascript functions I am getting only function foo(){ alert("This is an alert"); } I know to use these type of functions

  • Secure Menu Items Based on User

    - by Mike Wills
    On this winform application I am writing, I want to secure one menu item from most users. It runs a month-end and cannot be easily backed out if accidentally run. The menu option opens up a window to prompt the user for some information before processing. I don't care where exactly I do the check, but I want to be sure only certain users can run this function. A Google search (on my question title above) didn't turn up anything obvious. Can anyone point me in a direction to pick up who is signed into Windows and how to check if they are authorized?

  • increasing speed and efficiency of ajax call

    - by user1048824
    I'm not the most disciplined dev, dont know standards and am self-taught so bear with me. I create stuff very logically and fast but not always using 'programming standards'. I have a mobile app using geolocation API. it gets thousands of places from my db and makes gmaps v3 markers for the ones around the user's current location. there is an ajax call from my JS to an aspx page that calls the database, makes a json string, and sends the json string to the javascript that then creates the google map markers. would i save time if the json string was in a flat file? im not sure if, generally speaking, accessing a sql db from an aspx page is faster than c# file i/o on a flat file with pre-rendered JSON. (of course, using the flat file, it would update everytime the db is updated)

  • Team activity/game for illustrating design in a SCRUM environment

    - by njreed.myopenid.com
    I'm looking for a team building / training activity for some of my scrum teams. I want something that really illustrates the flexibility that the team has when implementing stories to define the scope and complexity of the feature themselves. Most of the teams have long-term waterfall experience and are used to having a well-defined specification. I'm looking for something that illustrates the need for the team to vary the scope of what they are building themselves, dependent on the time and resources available. I couldn't find anything at tastycupcakes.com and Google wasn't much help. Maybe someone has prepared something themselves they would care to share?

  • Is there a tool that automatically saves incremental changes to files while coding?

    - by Bob.
    One of my favorite features of Google docs is the fact that it's constantly automatically saving versions of my document as I work. This means that even if I forget to save at a certain point before making a critical change there's a good chance that a save point has been created automatically. At the very least, I can return the document to a state prior to the mistaken change and continue working from that point. Is there a tool with an equivalent feature for a Ruby coder running on Mac OS (or UNIX)? For example, a tool that will do an automatic Git check-in every couple of minutes to my local repository for the files I'm working on. Maybe I'm paranoid, but this small bit of insurance could put my mind at ease during my day-to-day work.

  • Bible reference books (PHP / MySQL / Unix)

    - by Josh K
    I'm looking for some nice heavy books to liter around my desk and make it look like I'm a hard core programmer. On the occasion that I might want to look something up they will also need to be useful dependable books. I'm looking for the equivalent bible in PHP, MySQL, and Unix. Should be laid out with some chapters I can actually read, along with having an in-depth reference to that particular subject. I know that the majority of this can be found on Google, but I would prefer it in book form.

  • Creating audit triggers in SQL Server

    - by Mike C.
    I need to implement change tracking on two tables in my SQL Server 2005 database. I need to audit additions, deletions, updates (with detail on what was updated). I was planning on using a trigger to do this, but after poking around on Google I found that it was incredibly easy to do this incorrectly, and I wanted to avoid that on the get-go. Can anybody post an example of an update trigger that accomplishes this successfully and in an elegant manner? I am hoping to end up with an audit table with the following structure: ID LogDate TableName TransactionType (update/insert/delete) RecordID FieldName OldValue NewValue ... but I am open for suggestions. Thanks!

  • Redirect to hash URL

    - by r1987
    I'm building a site with a hashchange on wordpress, all working good. It just loads a single.php template file into a div. The problem is that i can still access my single url (http://www.mydomain.com/my-single-post). Since its not having any head and style tags with it, i don't want people to go over there. Also google has picked up the direct links, because I use the href attribute to load content into the div. So my question is: If someone clicks a link lets say in a forum, http://www.mydomain.com/my-single-post , is it possible to redirect him instantly to http://www.mydomain.com/#my-single-post ? I have researched that it has something to do with .htaccess, but I also have Pages, where i don't want the hash infront of the page-name.

  • Language Prejudices

    - by paranoid_pedlar
    I've been researching programming languages, in hopes of learning to program. Since I've heard a lot of good things about Ruby, I went ahead and purchased The Pragmatic guide to Ruby. I understand that there is a lot of hype about Ruby on Rails. Because ruby lets you program scripts, applications, and internet helped me to decide on learning Ruby vs other languages. Today I watched a talk about google go, and it's really caught my attention. Coincidently I stumbled on a talk about jruby. I've been under the impression that java applications are bloated an slow. However the speaker made a point of what is wrong with Ruby, and how Jruby diagnosed Ruby's shortcomings. All that said. I would like to hear peoples opinions on Jruby vs Ruby, and if Ruby is working on fixing these "short comings". Also, how do you, the programming community feel about "go" and if I'm making a mistake learning Ruby instead of go, or Jruby. Appreciate your advice and opinions Thanks,

Anyways I have a saved webpage on my desktop that when i open it in google chrome i want it to show a specific URL instead of its current location. Any ideas how i might get this to work?

    - by user3793685
    Good day! I have 2 Projects in my Eclipse. MainActivity1 and MainActivity2 are the names of the activities. The MainActivity2 is connected to the MainActivity1 via Project in the properties of the MainActivity1. So far, I can call the package of the MainActivity2 from the MainActivity1. Now, below are my problem: I have a button in MainActivity1. What I want to do is after I click on the button in the MainActivity1, it runs the MainActivity2 project and some variables will be passed on to the MainActivity2. I've been searching in google for a while now and I couldn't get the right keyword for it. I've checked some of the questions here in StackOverflow but I'm unable to locate the problem similar to mine with calling and running the MainActivity2 class from the MainActivity1.java I'm a noob in Android Java but have knowledge in other OOP. Any tips will be a great help. Thanks

  • how do i detect \r\n in a u_char type of buffer?

    - by aDi Adam
    i am trying to construct http content from packet sniffing in C. right now i am able to save all the packets in a file but i want to get rid of the headers in the first packet. they are also being saved as per they are a part of tcp payload. the actual body after the header starts after double "crlf" or \r\n\r\n in http response. how do i detect \r\n so that i can only save the following part of the buffer in the file. the buffer is u_char type. i cant figure out the command or the part i looked on google and other places but i mostly find c# commands, nothing in C.

  • Enumerate all k-partitions of 1d array with N elements?

    - by user301217
    This seems like a simple request, but google is not my friend because "partition" scores a bunch of hits in database and filesystem space. I need to enumerate all partitions of an array of N values (N is constant) into k sub-arrays. The sub-arrays are just that - a starting index and ending index. The overall order of the original array will be preserved. For example, with N=4 and k=2: [ | a b c d ] (0, 4) [ a | b c d ] (1, 3) [ a b | c d ] (2, 2) [ a b c | d ] (3, 1) [ a b c d | ] (4, 0) I'm pretty sure this isn't an original problem (and no, it's not homework), but I'd like to do it for every k <= N, and it'd be great if the later passes (as k grows) took advantage of earlier results. If you've got a link, please share.
