  • Switching to Java from C++: What are the key points?

    - by Roddy
    I'm an experienced developer, but most of my OO programming experience has been with C++ (and a little Delphi). I'm considering doing some Android work, hence Java. Coming from the C++ background, what areas of Java are most likely to surprise/annoy/delight me? I felt sure this would already have been asked, but my searches haven't turned up a similar question. CW, of course.

  • VS 2010 SQL Update for SQL Statement

    - by Mike Tucker
    Please bear with me as I'm just beginning to learn this stuff. I have a VS 2010 Web project up and I'm trying to understand how I can make a custom UpdateCommand (Because I chose to write my own SQL statement, I do not have the option for VS 2010 to auto generate an update command for me.) Problem is: I don't know what the UpdateCommand should look like. Here is my Select: SELECT * FROM Dbo.MainAsset, dbo.Model, dbo.Hardware WHERE MainAsset.device = Hardware.DeviceID AND MainAsset.model = Model.DeviceID Which, VS 2010 turns into: SELECT MainAsset.pk, MainAsset.img, MainAsset.device, MainAsset.model, MainAsset.os, MainAsset.asset, MainAsset.serial, MainAsset.inyear, MainAsset.expyear, MainAsset.site, MainAsset.room, MainAsset.teacher, MainAsset.FirstName, MainAsset.LastName, MainAsset.Notes, MainAsset.Dept, MainAsset.AccountingCode, Model.Model AS Hardware, Model.pk AS Model, Model.DeviceID, Hardware.Computer, Hardware.pk AS Expr3, Hardware.DeviceID AS Expr4 FROM MainAsset INNER JOIN Hardware ON MainAsset.device = Hardware.DeviceID INNER JOIN Model ON MainAsset.model = Model.DeviceID How would I approach updating one column, say "MainAsset.site" if that's changed in the Gridview DDL? Any help constructive help would be appreciated. Thank you.

  • phpDocumentor to wiki?

    My company is working on end user/developer docs using mediawiki. I'd like to take a lot of the API docs that phpdoc spit out (for specific functions/methods) and have it in wiki markup for easy transfer. Any solutions out there for getting wiki markup or wiki output from phpDoc? I've looked around and found nothing.

  • Iterating through a range of dates in Python

    - by ShawnMilo
    This is working fine, but I'm looking for any feedback on how to do it better. Right now I think it's better than nested loops, but it starts to get Perl-one-linerish when you have a generator in a list comprehension. Any suggestions are welcome. day_count = (end_date - start_date).days + 1 for single_date in [d for d in (start_date + timedelta(n) for n in range(day_count)) if d <= end_date]: print strftime("%Y-%m-%d", single_date.timetuple()) Notes: I'm not actually using this to print; that's just for demo purposes. The variables start_date and end_date are datetime.date objects, because I don't need the timestamps (they're going to be used to generate a report). I checked the StackOverflow questions which were similar before posting this, but none were exactly the same. Sample Output (for a start date of 2009-05-30 and an end date of 2009-06-09): 2009-05-30 2009-05-31 2009-06-01 2009-06-02 2009-06-03 2009-06-04 2009-06-05 2009-06-06 2009-06-07 2009-06-08 2009-06-09

    - by Dhawal
    We are in web era standalone applications are almost gone everyone wants their internet application to run inside browser, programming languages like Ruby, Python and scala are becoming more and more mainstream. Sometimes I wonder what these programming language offer which make them top choice of IT companies, if I plan to become a freelance web developer is it worth learning C# or Java. I read beginner's book for both of them, but to master any of them require some time investment.

  • Computer Science + CFA

    - by scatman
    I still have one semester to finish my MS in Computer Science, and I am already working for a software development company. I took some accounting courses as electives (accounting 1-2 and finance) and I found them interesting and easy. Is it worth it to do CFA? I don't want to change majors, i.e. I still want to be a developer, but would it help if I did CFA?

  • Mercurial - How do you export your repo's source to a production site?

    - by orokusaki
    I've tried using archive in Tortoise HG by opening my repo change log. This doesn't seem to be anything like SVN's export command, where I can simply export a remote repository to the current directory. I use this to get a clean copy of my source for production (without notes and repository data). How can I do something like this in HG? Or, should I just use clone and deal with the repo related data manually? BTW, I need to do this all via command line since I'm not going to be using Tortoise HG on my Linux server. Any help is much appreciated.

  • LINQ to SQL - Get only substring from a field

    - by domanokz
    I'm studying ASP.NET MVC and I use LINQ to SQL for model. I have a table named "Note" with the fields "Title" and "Content". The "Content" field can contain thousand characters. What I want to do is to display the LIST of notes in a page. I use table with two columns, for "Title" and SUBSTRING of the "Content" (50 characters). My problem is, I don't know how to edit the model so that it will display only the substring of the "Content". Thanks in advance!

  • What's the best way to return something like a collection of `std::auto_ptr`s in C++03?

    - by Billy ONeal
    std::auto_ptr is not allowed to be stored in an STL container, such as std::vector. However, occasionally there are cases where I need to return a collection of polymorphic objects, and therefore I can't return a vector of objects (due to the slicing problem). I can use std::tr1::shared_ptr and stick those in the vector, but then I have to pay a high price of maintaining separate reference counts, and object that owns the actual memory (the container) no longer logically "owns" the objects because they can be copied out of it without regard to ownership. C++0x offers a perfect solution to this problem in the form of std::vector<std::unique_ptr<t>>, but I don't have access to C++0x. Some other notes: I don't have access to C++0x, but I do have TR1 available. I would like to avoid use of Boost (though it is available if there is no other option) I am aware of boost::ptr_container containers (i.e. boost::ptr_vector), but I would like to avoid this because it breaks the debugger (innards are stored in void *s which means it's difficult to view the object actually stored inside the container in the debugger)

  • Prolem with if function

    - by Ryan
    Hi, something seems to be wrong with the first line of this if function, seems alright to me though. if ($count1 == sizeof($map) && $count2 == sizeof($map[0])){ echo ";"; }else{ echo ","; } This is the error I get (line 36 is the first line of the above line.) Parse error: parse error in C:\wamp\www\game\mapArrayConvertor.php on line 36 EDIT: The OP notes in an answer below that the error was a missing semi-colon on line 35 and not the code included in the question.

  • Sql Server query performance

    - by Macros
    I have a stored procedure on a busy database which constantly come out top in the list of expensive queries (by some way). The query is very simple, it takes a single parameter (@ID, int) which is the primary key of the table, and selects the record that matches that ID. The primary key is an identity field with a clustered index, so I am stumped as to how to optimise this any further? The query is as follows CREATE PROCEDURE [dbo].[P_Call_Get] @ID int = null AS select ID, AppID, AgentID, AgentLogin, Ext, VDN, VDNName, Skill, SkillName, CallFrom, TelNoFrom, ParentCallID, CallStart, ACWStart, CallEnd, Outcome, StageID, TxTo, TxSuccess, ServiceID, DiallerID, CRC, TSCallID, CallDirection, [Manual], CallBackAgent, CallBackDateTime, Notes from P_Call where (ID = @ID or @ID is null) Not sure the best way to post the execution plan - all it shows is that 100% of the operation is taken up by the clustered index scan
