• Associate specific file extensions with my delphi app - any library for this?

  - by michal

  Hi, so far if I had to associate the file extension with my application I used to simply modify the registry. However I haven't been doing it for years, and I'm afraid the things might have changed a bit. I have no idea how to prevent registry access restrictions in Windows 7 / Vista (if there are any for HKEY_CLASSES_ROOT). Thus I'm looking for some delphi library, unit, code snippet or whatever which works reliably under XP, Vista and 7. Is there any which handles "backup" as well? By backup I mean possibility to revert the changes to the previous association ... Thanks in advance, m.

• Java import from other directory

  - by heldopslippers

  Hi People! I am building a Enterprise Service Bus (ESB) with Java. I won't get into details But I have to build multiple servers who make use of the same classes. I have the following directory structure: /server1 -Main.java /server2 -Main.java /com -Database.java I want to import from the Main.java class for example the Database.class. But of course the following statements won't work: import com.Database; I am working with the javac compiler in the command line (so not eclipse stuff or whatever. just TextMate and the command line). And I found a (pretty stupid) solution by creating a symbolic link in the servers to the com directory. But that is not really an ideal solution. Does anybody have a better one?? THANXS in advanced!! :D

• iPhone app -- are plists the way to handle default values and other languages?

  - by d_CFO

  I wrote my first program almost fifty years ago (yes, coding is still a blast, managing big projects with many programmers was not), but my Von Neumann thinking gets in the way. I want to (a) load default values and (b) account for multiple languages more elegantly (?) than 60-plus iterations of NSLocalizedString. Can I park all of this data into what amounts to a record with fields like this: (key value stuff), (tweak-able user prompt / screen name / whatever), (tasteful default), (user-supplied value)? NSUserDefault has worked well so far; Core Data looks like overkill (?), and sql lite, well, where's Oracle when you need it?

• How do you keep Cocoa controllers from getting too big?

  - by zoul

  Hello! Do you have some tricks or techniques to break Cocoa controller classes into smaller chunks? I find that whatever I do the controllers end up being one of the more complicated classes in my design. The basic stuff is simple, but once I have several pop-overs or action sheets running, things get uncomfortably complex. It's not that bad, but still I would like to refactor the code into several standalone chunks. I thought about categories, but the code is not that independent (a lot of times it needs to tap into viewWillAppear, for example) and I find that I spend a long time fighting the compiler. I also thought about adding functionality in layers using inheritance, but that feels like a hack.

• How should I deal with sqlite errors?

  - by Dustin

  I have a long running application written in a mix of C and C++ that stores data in sqlite. While I am confident that committed data will remain available (barring mechanical failure) and uncommitted data will not be, it's not clear to me what I can do with this sort of middle state. I do a large number of inserts in a transaction and then commit it. When an error occurs on a given statement, I can schedule it to be attempted at some point in the future. It sounds like some errors might implicitly rollback my transaction (which would be undesirable if true). A larger problem is what happens when my commit itself fails. Currently, I'm just going to continue to retry it until it works. I would expect that whatever would cause my commit to fail may very well also cause a rollback to fail. What is the recommended mechanism for error handling in such a situation?

• Using adaptive step sizes with scipy.integrate.ode

  - by Mike

  The (brief) documentation for scipy.integrate.ode says that two methods (dopri5 and dop853) have stepsize control and dense output. Looking at the examples and the code itself, I can only see a very simple way to get output from an integrator. Namely, it looks like you just step the integrator forward by some fixed dt, get the function value(s) at that time, and repeat. My problem has pretty variable timescales, so I'd like to just get the values at whatever time steps it needs to evaluate to achieve the required tolerances. That is, early on, things are changing slowly, so the output time steps can be big. But as things get interesting, the output time steps have to be smaller. I don't actually want dense output at equal intervals, I just want the time steps the adaptive function uses.

• Why does py2exe remove `help` and `license`?

  - by cool-RR

  I packaged my Python app with py2exe. My app is a wxPython GUI, in which there is an interactive Python shell. I noticed that I can't do help(whatever) in the shell. I investigated a bit and discovered that after the py2exe process, 3 items were missing from __builtin__. These are help, license, and another one I haven't discovered. Why is this happening and how can I stop it? I want the users of my program to be able to use the help function of Python.

• Best way to convert between [Char] and [Word8]?

  - by cmars232

  I'm new to Haskell and I'm trying to use a pure SHA1 implementation in my app (Data.Digest.Pure.SHA) with a JSON library (AttoJSON). AttoJSON uses Data.ByteString.Char8 bytestrings, SHA uses Data.ByteString.Lazy bytestrings, and some of my string literals in my app are [Char]. This article seems to indicate this is something still being worked out in the Haskell language/Prelude: http // hackage.haskell.org/trac/haskell-prime/wiki/CharAsUnicode And this one lists a few libraries but its a couple years old: http //blog.kfish.org/2007/10/survey-haskell-unicode-support.html [Links broken because SO doesn't trust me -- whatever...] What is the current best way to convert between these types, and what are some of the tradeoffs? I don't want to pick something that is obsolete... Thanks!

• C++ new line not translating

  - by m3n

  First off, I'm a complete beginner at C++. I'm coding something using an API, and would like to pass text containing new lines to it, and have it print out the new lines at the other end. If I hardcode whatever I want it to print out, like so printInApp("Hello\nWorld"); it does come out as separate lines in the other end, but if I retrieve the text from the app using a method that returns a const char then pass it straight to printInApp (which takes const char as argument), it comes out as a single line. Why's this and how would I go about to fix it?

• Use CSS (and maybe JavaScript) to make an element be square (or maintain a specific aspect ratio)

  - by David Pfeffer

  I have a div that I want to have the following characteristics: Width = 50% of its parent element Height equal to whatever it needs to be in order to maintain a certain aspect ratio. I need to use percentages because the object will resize left-right when the browser is resized. I want the object to be resized top-bottom to ensure the object maintains the same aspect ratio. I don't think there's any way to use pure CSS to do this, but does anyone know of a way? Alternatively, is there an easy JavaScript way to do this? (JQuery is fine.)

• How do you extract data from a Date/Time widget from a C++ MFC dialog in VS2008

  - by jkerian

  This is a fairly basic question, but I haven't been able to find any from-to guides from VS6-VS2008. I have a dialog box that contains controls of various types, I've discovered the way of auto-generating OnBnClickedMyFooBarButtonHere() methods via the Properties dialog on the dialog editor. I can also use CWnd::GetDlgItemText(int ,CString &) to extract text, and the oddly paramaterized GetDlgItemInt(int, bool*, bool) to extract signed integers, but is there really no other option for a Date or Time value other than Manually adding in all the DDX_ crap that the class wizard used to do in VS6 Using GetDlgItemText and then parsing whatever it gives me?

• Easiest solution to sync an offline (local desktop application) database with a central server and multiple pc's?

  - by tyfius

  I have a desktop application which uses a local database. (This can be SQLite, SqlCe, PostgreSQL or any other database I will be able to install locally, I haven't decided which one to use yet.) The plan is to achieve the following: A user can subscribe to some kind of cloud service. If he does his local database should be synced with the online database (one for all users, or one per user, whatever the easiest solution is) so he will be able to sync his local database data between multiple PC's, can access his data online. (Much like dropbox does for files.) What is the best, easiest (and preferably cheapest) solution to achieve this? I am looking into DataObjects.net but I can't find much documentation about their Sync feature. Or, are there other alternatives? For example, I start with some kind of cloud service which allows local caching and use the local caching for users who do not subscribe to the service. Any pointers, tips or experiences are welcome.

• Java vs C# - AddActionListener vs event subscription

  - by S.O.

  Very simple question from one somewhat new to Java: when adding an event handler (or whatever it is called in Java) to a Control, MUST it be an object? I mean, in C# I can do control.event += System.eventHandler(methodThatHandlesEvent) Sure, that's because we have delegate types in C#, but I was wondering if I can choose which method would be called when an event is raised in Java? I mean, in Java I can have something like control.AddActionListener(objectWhichClassImplementsActionListener) And then I have the stupid actionPerformed method in this class, which is the only method that is called. I know, there are more kinds of listeners, but I can't have a "ActionListenerHandler" class in which I implement several actionPerformed methods that can be assigned to different controls?

• Query for multiple joins

  - by Shailaja

  i have 3 tables named dataset,dataelem and transformdataelem with column names as below: main.Dataset ------------ datasetID (PK) applicationID main.Dataelem ------------- dataelemID(PK) datasetID(FK) dataelemname biztermID main.Transformdataelem ---------------------- OutputdataelemID InputdataelemID My requirement is: All tables are referenced. Extract all the dataelemId rows from dataelem table where applicationID of dataset table is equal to 1044 and biztermid shud be null. Then whatever resultant dataelemIDs from the above query should be matched with outputdataelemID of Transformdataelem table and we shud get the respective input dataelemId's. Again with these matched inputdataelemID's we shud get the dataelemname's from datelem table.

• MapView without Zoom Levels Android

  - by RyanInBinary

  I'm using the MapView object for my app and it's working really well. But I noticed that it "locks" to zoom levels, even if you don't use them. For instance, if you pinch to zoom and barely do it, the view will "snap" either forward or backward to whatever the closest zoom level is. The native google maps application does not do this at all. You can barely pinch, and it'll accept it (there are no 'hard' zoom levels built in). How can I get my mapview to mirror that?

• how to customize the filter when following a stream in wireshark?

  - by jim

  when selecting a packet and choosing to follow the stream, wireshark automatically sets a filter that looks something like this: (ip.addr eq 10.2.3.8 and ip.addr eq 10.2.255.255) and (udp.port eq 999 and udp.port eq 899). i'd like to be able to set that myself when following the stream, but have not been able to identify where to do that. setting the display filter has no effect. in fact, after following the stream, whatever display filter is currently set will be replaced by the follow stream formatted filter. is customizing the follow stream filter even possible? thanks

• Defining action on window load

  - by zac

  I am trying to get a page to display specific properties depending on whether or not a specific cookie is set... I am trying this var x = readCookie('age'); window.onload=function(){ if (x='null') { document.getElementById('wtf').innerHTML = ""; }; if (x='over13') { document.getElementById('wtf').innerHTML = ""; }; if (x='not13') { document.getElementById('emailBox').innerHTML = "<style type=\"text/css\">.formError {display:none}</style><p>Good Bye</p><p>You must be 13 years of age to sign up.</p>"; }; } It always just defaults to whatever is in the first if statement... I am still learning my javaScript so I am sure this is sloppy.. can someone please help me get this working?

• Reflection for Class of generic parameter in Java?

  - by hatboysam

  Imagine the following scenario: class MyClass extends OtherClass<String>{ String myName; //Whatever } class OtherClass<T> { T myfield; } And I am analyzing MyClass using reflection specifically (MyClass.class).getDeclaredFields(), in this case I will get the following fields (and Types, using getType() of the Field): myName --> String myField --> T I want to get the actual Type for T, which is known at runtime due to the explicit "String" in the extends notation, how do I go about getting the non-genetic type of myField?

• Email marketing campaigns [closed]

  - by Bradley Herman

  We're working on building an email marketing campaign for our company and once again, my boss (designer) and I (developer) are butting heads... She wants to create one big image for each of these emails and I'm trying to steer her towards using the traditional header-content-footer method so the text within the content will be viewable when images are blocked. Obviously as a designer, she believes in a happy world where 100% of people will open it to see whatever awesome design she made and click to go to our site. Are there any good statistics or case-studies anyone has seen out there that would help support my stance of design being used to enhance content than design being content?

• Does remove a DOM object (in Javascript) will cause Memory leak if it has event attached?

  - by seatoskyhk

  So, if in the javascript, I create a DOM object in the HTML page, and attach event listener to the DOM object, upon I remove the the DOM from HTML page, does the event listener still exist and causing memory leak? function myTest() { var obj = document.createElement('div'); obj.addEventListener('click', function() {alert('whatever'); }); var body = document.getElementById('body'); // assume there is a <div id='body'></div> already body.appendChild(obj); } // then after some user actions. I call this: function emptyPage() { var body = document.getElementById('body'); body.innerHTML = ''; //empty it. } So, the DOM object, <div> inside body is gone. But what about the eventlistener? I'm just afraid that it will cause memory leak.

• A PHP Function that verify code language

  - by tymc

  Hi, I have a form with 2 textareas; the first one allows user to send HTML Code, the second allows to send CSS Code. I have to verify with a PHP function, if the language is correct. If the language is correct, for security, i have to check that there is not PHP code or SQL Injection or whatever. What do you think ? Is there a way to do that ? Where can I find this kind of function ? Is "HTML Purifier" http://htmlpurifier.org/ a good solution ?

• NoMethodError using Memcached Sinatra-style

  - by sevennineteen

  I've just installed Memcached on my Mac and updated my Sinatra app configuration as described in Heroku's documentation, but I'm getting a NoMethodError when trying to use the hash-based syntax they specify: >> CACHE['color'] = 'blue' >> CACHE['color'] Using explicit get and set methods as below seems to work fine. >> CACHE.set('color', 'blue') >> CACHE.get('color') If necessary I can use the latter syntax, but the former seems more elegant. I haven't tested this on Heroku's environment since I'd like whatever implementation I use to work on my local environment as well. Thanks!

• Do you know any build systems with decent support for parallelization?

  - by dahpgjgamgan

  Hi, I am looking for a build system (working on ms windows) that has good support for parallelization of tasks/targets (or whatever you call them). To be more specific - during build (that is initiated on MS Windows machine) I need to copy source files to a number of different machines (which are not necessarily running Windows) and start a remote job on each of them - and I really like to do that on all machines at once. Does anyone know a build system that's capable of executing such a task in parallel. From what I googled, the options currently available are: -j switch in make - but i don't know if nmake supports this -some custom nAnt tasks -msbuild has some form of support for parallelization - seems similiar to make (meaning you don't specify what to do in parallel, just specify that it would be nice to build things that way) -fake (f# make) is written in functional programming language which are known to have good parallelization support - but I'm not very skillful in functional programming area. Any other solutions I could explore?

• auto_inline - inadequate documentation

  - by Mick

  I want to disable inlining for a particular function. What the compiler does for everything else should be as specified in the project properties. I found a page on a forum which suggested the following: #pragma auto_inline(off) void func() { } #pragma auto_inline() The author suggested that calling auto_inline() with no arguments will set the compiler to revert to doing whatever the default action was before the call to auto_inline(off). Can anyone confirm that this works for visual studio 2008? I ask because the VS2008 documentation makes no mention at all of what happens if you call this function with no arguments.

• Sorting and displaying a custom QVariant type.

  - by Kranar

  Hello, I have a custom type I'd like to use with QVariant but I don't know how to get the QVariant to display in a table or have it sort in a QSortFilterProxyModel. I register the type with Q_DECLARE_METATYPE and wrote streaming operators registered via qRegisterMetaTypeStreamOperators but for whatever reason when I use the type with a table model, it doesn't display anything and it doesn't sort. I should specify that this custom type can not be modified. It has a copy and default constructor, but I can not go in and modify the source code to get it to work with QVariant. Is there a way of non-intrusively getting the behaviour I'd like?
