  • Javascript: How to detect if a word is highlighted

    - by fterh
    I'm writing a Firefox addon that is triggered whenever a word is highlighted. However I need a script that detects when a word is highlighted, and I'm stuck. An example would be nytimes.com (when you're reading an article and you highlight a word, the reference icon pops up). However the nytimes.com script is super complex. I'm 16 and not much of a programmer, so that is definitely way out of my league.

  • New to CakePHP -> How To Add Columns To a MySQL Table?

    - by walden
    I had a website made for me a long time ago, and the programmer did it in CakePHP. I'm now editing his scripts. I added a couple columns to a table, and found that doing saveField() on the new column does not do anything. How do I make CakePHP recognize the new columns? I'd appreciate your help. I'm not too familiar with CakePHP, so please go easy on me =)

  • C++ equivalent to Python's doctests?

    - by drcraig
    I think the concept of Python's doctests is brilliant, and as a C++ programmer at a real-time shop, I'm quite jealous. We basically have no unit test capability, which is a severe hindrance. I've seen C++Unit, etc, but is there anything that can extract test cases out of comments like Python's doctests rather than putting them in the code directly?

  • C struct memory layout?

    - by Eonil
    I have C# background. Very newbie to low level language like C. In C#, memory layout by compiler by default, and I have to specify some special attribute to override this behavior for exact layout. As I know, C does not re-align by default. But I heard there's a little re-aligning behavior which very hard to find. Can I know about C's memory layout behavior? (what should be re-aligned and not)

  • C++: Is windows.h generally an efficient code library?

    - by Alerty
    I heard some people complaining about including the windows header file in a C++ application. They mentioned that it is inefficient. Is this just some urban legend or are there really some real hard facts behind it? In other words, if you believe it is efficient or inefficient please explain how this can be with facts. I am no C++ Windows programmer guru. It would really be appreciated to have detailed explanations.

  • Is developing iPhone apps in any language other than Objective-C ever a truly viable solution?

    - by David Foster
    I hear all this stuff about crazy ways to build iPhone apps using Ruby or C# under .NET or the like. Even stuff about developing apps on Windows using Java, or auto-generated apps using Flash CS5 or something. Now, I've never really spent any time at all investigating these claims—I just brushed them off as clumsy or cumbersome or down-right claptrap—but I'm a proud Objective-C programmer who's perhaps a little worried as to whether there's any truth in all of this?

  • free video streaming API

    - by rl123
    Hi, I'm trying to build a website that will allow user to upload video files and show them as a streaming video. I'm a complete newbie in the streaming world so I don't know exactly how to do that, and I definitely don't want to reinvent the wheel. Are there any free platforms that I can use for that? Do I need a streaming server, or is there a special kind of player I can use that does not require dedicated server? Thanks!

  • Doing a count over a filter query efficiently in django

    - by apple_pie
    Hello, Django newbie here, I need to do a count over a certain filter in a django model. If I do it like so: my_model.objects.filter(...).count() I'm guessing it does the SQL query that retrieves all the rows and only afterwards does the count. To my knowledge it's much more efficient to do the count without retrieving those rows like so "SELECT COUNT(*) FROM ...". Is there a way to do so in django?

    - by Brad Hein
    I've written an Android app wich various abstract classes that perform useful functions. These functions could be leveraged in other apps.

  • SQLAlchemy: an efficient/better select by primary keys?

    - by hadrien
    Yet another newbie question.. Let's say I have an user table in declarative mode: class User(Base): __tablename__ = 'user' id = Column(u'id', Integer(), primary_key=True) name = Column(u'name', String(50)) When I have a list of users identifiers, I fetch them from db with: user_ids = [1, 2, 3, 4, 5] users = Session.query(User).filter(User.id.in_(user_ids)).all() I dislike using in_ because I think I learned it has bad performance on indexed fields (is that true/false?). Anyway, is there a better way doing that query? Thanks!

  • What are real world examples of when Linked Lists should be used?

    - by oo
    Another programmer was mentioning that they haven't found a use case for using a linked list data structure in any professional software in his career. I couldn't think of any good examples off the top of my head. He is mostly a C# and Java developer Can anyone give some examples where this was the correct data structure to solve a particular real world problem? Related: What is a practical, real world example of the Linked List?

  • Searching a Better Solution with Delegates

    - by spagetticode
    Hey All, I am a newbie in C# and curious about the better solution of my case. I have a method which gets the DataTable as a parameter and creates a List with MyClass's variables and returns it. public static List<Campaigns> GetCampaignsList(DataTable DataTable) { List<Campaigns> ListCampaigns = new List<Campaigns>(); foreach (DataRow row in DataTable.Rows) { Campaigns Campaign = new Campaigns(); Campaign.CampaignID = Convert.ToInt32(row["CampaignID"]); Campaign.CustomerID = Convert.ToInt32(row["CustomerID"]); Campaign.ClientID = Convert.ToInt32(row["ClientID"]); Campaign.Title = row["Title"].ToString(); Campaign.Subject = row["Subject"].ToString(); Campaign.FromName = row["FromName"].ToString(); Campaign.FromEmail = row["FromEmail"].ToString(); Campaign.ReplyEmail = row["ReplyEmail"].ToString(); Campaign.AddDate = Convert.ToDateTime(row["AddDate"]); Campaign.UniqueRecipients = Convert.ToInt32(row["UniqueRecipients"]); Campaign.ClientReportVisible = Convert.ToBoolean(row["ClientReportVisible"]); Campaign.Status = Convert.ToInt16(row["Status"]); ListCampaigns.Add(Campaign); } return ListCampaigns; } And one of my another DataTable method gets the DataTable from the database with given parameters. Here is the method. public static DataTable GetNewCampaigns() { DataTable dtCampaigns = new DataTable(); Campaigns Campaigns = new Campaigns(); dtCampaigns = Campaigns.SelectStatus(0); return dtCampaigns; } But the problem is that, this GetNewCampaigns method doesnt take parameters but other methods can take parameters. For example when I try to select a campaign with a CampaignID, I have to send CampaignID as parameter. These all Database methods do take return type as DataTable but different number of parameters. public static DataTable GetCampaignDetails(int CampaignID) { DataTable dtCampaigns = new DataTable(); Campaigns Campaigns = new Campaigns(); dtCampaigns = Campaigns.Select(CampaignID); return dtCampaigns; } At the end, I want to pass a Delegate to my first GetCampaignList Method as parameter which will decide which Database method to invoke. I dont want to pass DataTable as parameter as it is newbie programming. Could you pls help me learn some more advance features. I searched over it and got to Func< delegate but could not come up with a solution.
