  • More swing design & actions

    - by takoi
    Im pretty new to gui programming so i've been reading through every post on this site about swing and design. Whats been answered over and over again is that one should have a class which handles all the action. Like this: (GUI being some JFrame) Now, this works great for one-way actions, like OpenDialog. But the actions for buttons in DialogA and B will have to have access to all the components (there will be many) in its dialog, and the controller. This is where im stuck. The only sane way i can see is to put it in DialogA/B but i would then need to pass the controller all the way down, through classes that dont even need it, and it'll get all spaghetti. Really dont want that. Someone must have encountered this problem before. So where should i put this Action? Or should i just drop the whole design?

  • View OS X Desktop on windows remotely at higher resolution then hosting machine

    - by Elijha
    I have a new macbook air 11, which I do some web based programming on, I have a windows box with a 1920x1200 display which I'd like to use to view the mac desktop and keep working at home when I can - taking advantage of the higher resolution screen and full sized keyboard/mouse. I don't think VNC or such is the answer I'm looking for as it would restrict the display to the airs 1366x768 - negating the main benefit more lines of text on screen. From some rudimentary googleing I think I'm after some sort of x-windows / x-11 remote display. But I'm not a Linux user and any discussion seems to be about linux os x or windows Linux setups. Can anyone provide a clear set of instructions on how to do this or an application that can do this.

  • Avaliable parallel technologies in .Net

    - by David
    I am new to .Net platform. I did a search and found that there are several ways to do parallel computing in .Net: Parallel task in Task Parallel Library, which is .Net 3.5. PLINQ, .Net 4.0 Asynchounous Programming, .Net 2.0, (async is mainly used to do I/O heavy tasks, F# has a concise syntax supporting this). I list this because in Mono, there seem to be no TPL or PLINQ. Thus if I need to write cross platform parallel programs, I can use async. .Net threads. No version limitation. Could you give some short comments on these or add more methods in this list? Thanks.

  • C++ - Where do i start?

    - by richzilla
    Hi All, As a bit of a side project while I'm on my summer break from uni, I've decided to have a look at C++, and get the hang of the basics. I'm by no means a programming novice, I've done web development before with PHP and Ruby, and I've done a fair bit of work with compiled languages (Java / C#). However, C++ seems to be a more significant undertaking. Basically I'm wanting pointers to the best resources for learning C++, as well as some idea as to areas I could do with reading up on (That I might not have come across before). Any help would be hugely appreciated. Thanks

  • How do you manage battery health of your development devices when is always plugged in?

    - by Pentium10
    I know this question is not programming related, so for this I made community wiki. Developers are the best guys to answer the question. I am addressed to those that do development on devices that runs on batteries, like phones, gadgets etc. Probably you are constantly develop for them, and therefor they are always plugged in and charged at 100%. We develop mainly for smartphones and we have devices that were always above 90% charged in the last month or so. If a battery is always charged, it degrades it life cycle, so what steps you do to ensure decent battery drain to maximize the life of the batteries.

  • How to use default.ctp in cakephp

    - by Louis Stephens
    I just finished the "15 min Blog Post tutorial" included in the documentation for cakephp. I was asked for another tutorial to change the layout for first tutorial. However, I am fairly new to MVC programming/Cakephp and I have no real clue how to do so. Well, I know I need "default.ctp" placed in app/views/layouts/ and I presume I need to include to include my data? . . . I am really at a loss of what to do. I set up my default.ctp as I mentioned above, but when I go to localhost:9999/posts the layout is still the same. I guess I need to include a stylesheet (and if so, where?) I guess if someone can point me in the right direction to a beginner's guide to layout styling or how to use it I would greatly appreciate any help.

  • scikit learn extratreeclassifier hanging

    - by denson
    I'm running the scikit learn on some rather large training datasets ~1,600,000,000 rows with ~500 features. The platform is Ubuntu server 14.04, the hardware has 100gb of ram and 20 CPU cores. The test datasets are about half as many rows. I set n_jobs = 10, and am forest_size = 3*number_of_features so about 1700 trees. If I reduce the number of features to about 350 it works fine but never completes the training phase with the full feature set of 500+. The process is still executing and using up about 20gb of ram but is using 0% of CPU. I have also successfully completed on datasets with ~400,000 rows but twice as many features which completes after only about 1 hour. I am being careful to delete any arrays/objects that are not in use. Does anyone have any ideas I might try?

  • Extract data from uint8 to double

    - by HADJ AMOR HASSEN
    I have a C function receiving a uint8 pointer with another parameter which is its size (number of bytes). I want to extract double data from this buffer. Here is my code: Write(uint8* data, uint8 size) /* data and size are given by a callback to my function)*/ { double d; for (i = 0; i < size; i++) { d = ((double*)&data)[i]; printf(" d = %d\n"); } } The problem is that I am not receiving what I am sending within an external hardware. I guess that my cast is wrong. I tried other methods but without any good result. I am still not able to get what I send.

  • How to correctly migrate urls from custom asp.net solution to Wordpress?

    - by Marek
    I have a web site built using asp.net with ugly URLs like /DisplayContent.aspx?id=789564. I know how to migrate the database, but the Wordpress urls will be (naturally) different. Can I simply write some mapping or do I have to include a rewrite rule for each subpage (300 pages) in .htaccess? Should I provide a rewrite rule for each existing page that would transform a full old url to the known new url, like for example: /DisplayContent.aspx?id=789798 -> /2010-5-10/Title-Of-The-Post Even if I manage to migrate the URLs, the structure of the HTML for the new content will naturally be different. How does this affect SEO? Should I run asp.net and wordpress side by side and issue the redirects from the asp.net application? What is the most efficient solution to this kind of migration of URLs without doing PHP programming?

  • Computer/Application having trouble and getting slow while accessing Sql server through LAN, Network is fine

    - by user614297
    Hi, I have an web project in asp.net in one of my computers which are connected internally through LAN. The database is in Sql Server kept in another computer. The LAN is connected well. There is no connection error in my programming also. But sometimes in this particular system the page is taking long time to be open, sometime it is showing some exceptions(not everytime again and again). What can be the problem? How can it be solved? The same project is running good in other computers as well. My network seems ok, as I can acccess the computer hosting SQL server.

  • Does this pattern have a name?

    - by LK7jb
    Disclaimer: I'm trying to learn proper OO programming/design, so I'm pretty new to this stuff. I guess this is a general design patterns question, but I'll base my example on a game engine or something that renders objects to the display. Consider the following: How can this sort of separation between physical objects (e.g., cubes, spheres, etc.) and the rendering mechanism be achieved in an extensible manner? This design is not set in stone, and perhaps I've got something wrong from the start. I'm just curious as to how a problem like this is solved in real world code.

  • Looping in filemaker using a local variable

    - by Mike Davis
    Been programming in C# for a little bit - trying to use file maker and I cant believe it but I cant even get a simple for loop to work. What I want to do is simple: loop through for the amount of entries in my "amountOfRooms" field and create an entry in a table for each room. Sounds so simple, but I cant get it to work. Right now I have this: Set Variable[$cnt[Customers::AmountOfRooms]; value:1] Go to Layout["rooms"(Rooms)] Loop Exit Loop If[$cnt = Customers::AmountOfRooms] New Record / Request Set Variable[$cnt; Value: $cnt + 1] End Loop Exit Script No new records are created. I know the script is running because it does go to my layout, but doesnt create any new records. There is a "Repetition" field for my local variable - not sure how to use that or what it means? Any thoughts on how to do this simple loop? Thanks.

  • What is "with" used for in PHP?

    - by Jason
    I have come across this line in the eloquent ORM library: return with(new static)->newQuery(); I've never seen "with" used before, and cannot find it in the PHP documentation. I'm guessing "with" is a stop-word in most searches, so I am not even getting close. Never having encountered "with" in many years of programming PHP, I feel like I'm missing out. What does it do? I did come across one passing comment regarding the ORM, that mentioned "with" is no longer needed in PHP-5.4, but that was as much as was said.

  • How can I test if an input field contains foreign characters?

    - by zeckdude
    I have an input field in a form. Upon pushing submit, I want to validate to make sure the user entered non-latin characters only, so any foreign language characters, like Chinese among many others. Or at the very least test to make sure it does not contain any latin characters. Could I use a regular expression for this? What would be the best approach for this? I am validating in both javaScript and in PHP. What solutions can I use to check for foreign characters in the input field in both programming languages?

  • How can I make a boring project (another WordPress site) interesting?

    - by Christopher Altman
    WordPress is my example, but the question can be generalized to any technology that is not particularly interesting. To me, WordPress takes away the intellectually gratifying pieces of coding. I would rather write a new version of WordPress than write a WordPress theme and glue together some plugins. I am using WP because my company dictates the platform for some of our clients (I do not disagree with the choice from a business perspective, WP is quick and cheap to implement). My question is, how can I make my next WordPress project interesting? I want to advance my understanding of the fundamentals of programming (aka data structures, algorithms, and caching) but do not see how I can achieve this when coding another WP site. I have a fairly tight understanding of front-end technologies and believe I have made WP do things it was never intended to do. Examples are here and here. Solving front-end related problems is not as interesting as coding a full stack application. Any advice will help.

  • WIN32 visual c++

    - by mrbuxley
    I would like to write a simple program in c++. After the program is done i would like to get my answers in form of a graph or picture that would give some certain information if i click on a certain area. i have only written console apllications in c++ before and don't really have a clue where to start with the graphic part of it all. Can I write the first part of the program in console mode and some how run it under the WIN32 later? for ex what will happen to the cout<<"foo"; commands? Is there a simpler approach to do some very basic graphic programming.

  • how to make struct member pointer in assembly?

    - by sillis
    I`m trying to create a macro which would make easier to point to a structs member. Currently i am pointing to a structs member in assembly file using the STRUCT_NAME + offset method. For example if i want to point structs third member,i would have to do it like this: STRUCT_NAME + 3. This seems stupid way to do it, and if i insert more members in the struct, i have to update all the offset values in the code. Is there a way to point using STRUCT_NAME + macro(struct_name, member_name) ? I`m using texas instruments TMS320C28x hardware. Thanks!

  • WebGL on older Mac OS X versions (say 10.4)

    - by rotoglup
    Not really a programming related question but... I'd like very much to experiment with WebGL on my spare time. My current 'spare time' machine is a MacBook running Mac OS X Tiger (10.4.xx) and I'm unable to find a new browser supporting this OS. Firefox dropped support, Chrome too, and Safari idem. I read somewhere that this is due to a Quicktime bug that Apple won't fix. Does anyone have more information on this issue ? Does anyone have a clue or track to find a running implementation of WebGL on Mac OS X 10.4 ? Cheers,

  • [ADVICE] .NET Desktop Application - Client Server C#, SQL

    - by Rillanon
    Hi guys, Recently I've being given a chance to develop a PMS (Practice Management System) software for a small physiotherapy clinic. I'm a computer science student and my course is predominately told on Linux. However, my client runs all their computers on vista or Windows 7. My ideas are to develop the client front end in Visual C# and access a central postgresql server. I'm a beginner in Windows Programming so I'm after advice on best practice on implement user rights and access levels in C# (WPF or Windows FORM). I've had a look into Credential class in Visual C# and access control list but please share your thoughts. I'm probably way over my head on this but this is my first commercial project so I'm keen to test the waters. Cheers Ian

  • download a complete folder

    - by Christian
    Hi, in my app I use several png-graphics. For the present version they are installed with the app in the folder "graphic". I made while programming. Now I need some more png-graphics and I don't want to make each time an app-update. How can I manage it, that the app is downloading the png-files from my webserver without knowing the name. I am looking for something which compares the files on the webserver with the files on the iPhone and if there is a new (or newer) file download it. Or is it possible to make an plist-file with the graphics??

  • Mercurial: Recommended way of sending a whole repository to someone

    - by Svish
    I have done some programming and I have used Mercurial for source control. I now need to send all of my code to someone else (because they are going to take over). Since all copies of a mercurial repository is a full and real repository my first thought is to first do a clone of my repository without an update and then zipping and emailing that clone. Is this a good way, or is there a better way? For example when using the TortoiseHg Repository Explorer I can right-click on a changeset and under Export there are various options that looks like they could be doing something interesting, but I don't quite understand them or know which one to use.

  • What is the precedence of characters when sorting in MySQL, PHP, or just in general?

    - by FireCoding
    Question: Where can I find the precedence of characters when sorting in MySQL, PHP, or just in general on Linux and Windows OS? For example, everybody knows that a comes before b when performing an ascending sort on a string in MySQL. But what about other characters? Does the dollar-sign $ come before asterisk * ? Does a space come before an exclamation-mark? etc... What dictates the sort order? Does it use underlying ascii / UTF-8 values? Is it different for different technologies? Technologies to consider: Databases - MySQL / SQL / SQLite / Oracle / etc Programming languages (for string-sorting functions) - PHP / Javascript / ASP.NET / Visual C# / Python / Ruby / Objective C OS (i.e., sorting files by filename) - Windows / Linux / MacOS / iOS / Android
