  • Access to an "upper" instance of a class from another instance of a different class

    - by BorrajaX
    Hello everyone! I have a tricky question and probably what I want to do is not even possible but... who knows... Python seems very flexible and powerful... I'd like to know if there's a way to access to the class (or its fields) where an object is instanciated. Let's say I have: def Class1: def __init__(self): self.title = "randomTitle" self.anotherField = float() self.class2Field = Class2() and the class whose type will be the class2Field: def Class2: def __init__(self): self.field1 = "" self.field2 = "" # . . . # I'd like to know if there's a way to access the instance of Class1 from the instance of Class2 that is declared in Class1 (meaning, accessing the fields of Class1 from the variable self.class2Field in that Class1 instance) I know I can always change the init in Class2 to accept a Class1 parameter, but I'd like to know if there's another way of "climbing" through the class hierachy... Thank you very much!

  • Is html/javascript equivalent to as3/flex?

    - by DJ.
    Hello my fellow coders, As i notice for a while now (like everybody else in the industry), the RIA market is shifting from AS3/Flex to HTML/Javascript. What i would like to know is? Is html/javascript as powerfull as as3/Flex or are they entirely different. With other words can i build the exact same applictions with HTML(4/5) and Javascript as i can do with AS3/Flex? I'm not looking for the speed comparison? or bashing one technology over the other? I just want to know if is good for me to dive into javascript, JQuery...... PS. If there is a nother post on stackoverflow with the exacte question. please share the link. Thanks. Thank you.

  • Assign weight to a integer column for Sphinx search

    - by Daniel
    Hello: I have a note table with columns: title :string content :text rating :integer and a thinking_sphinx configuration: define_index do indexes :title, :sortable => true indexes :content end Then I can search the notes and assign weights to title and content to define the order or the result: Note.search "abc", :match_mode => :extended, :field_weights => { :title => 10, :content => 3 } Now I want to assign a weight to the rating column The type of the rating column is integer. The range of the rating is [1, 2, 3, 4, 5]. Can I just add weight at the :field_weights :field_weights => { :title => 10, :content => 3, :rating => 5 } or I need to do something else to make the note which has higer rating display first?

  • Quick, Beginner C++ Overloading Question - Getting the compiler to perceive << is defined for a spec

    - by Francisco P.
    Hello everyone. I edited a post of mine so I coul I overloaded << for a class, Score (defined in score.h), in score.cpp. ostream& operator<< (ostream & os, const Score & right) { os << right.getPoints() << " " << right.scoreGetName(); return os; } (getPoints fetches an int attribute, getName a string one) I get this compiling error for a test in main(), contained in main.cpp binary '<<' : no operator found which takes a right-hand operand of type 'Score' (or there is no acceptable conversion) How come the compiler doesn't 'recognize' that overload as valid? (includes are proper) Thanks for your time.

  • PHP 2d array question

    - by Neral
    Hello, So i have a 2 dimensional array that is used over several pages (session) $_SESSION ["Table"][$_SESSION ["count"]] [0] = $filename; $_SESSION ["Table"][$_SESSION ["count"]] [1] = $size; $_SESSION ["Table"][$_SESSION ["count"]] [2] = $floor; $_SESSION ["Table"][$_SESSION ["count"]] [3] = $phone; $_SESSION ["Table"][$_SESSION ["count"]] [4] = $network; $_SESSION ["Table"][$_SESSION ["count"]] [5] = $totalprice; This is used with a form so i can give in multiple input wich gets stored. But my question is how exactly can i calculate the AVERAGE of $total price of all given in results? Meaning for example i have 5 rows so this would mean 5 total prices. How exactly can i acces this value and count everything up / 5? This will happen in a other page so i would like to use sessions for this. /5 simply by count($_Session["table"]) , but really not sure about the other values. Kind Regards.

  • android settings (provider)?

    - by lorenzoff
    Hello to all, i'd like to substitute the default preferences setting activity (vertical, icon-title pair list) with a grid view that better fit a large landscape display. About, let's say, the audio preferences, i add an icon to a GridView and, on item click event, i use this code startActivityForResult(new Intent(android.provider.Settings.ACTION_SOUND_SETTINGS), 0); Is it possible to get the default settings icon? If i could use an ipotetic getDrawable(android.R.drawable.default_icon_for_audio_preferences_settings), I would to maintain the default icon also in my preferences grid. A preferences provider exists? Looking at my development device preferences i can see Wireless, call, audio, display and so on. I have to add the same preferences to my grid because i know a priori about their existence or there is a provider that can supply me this array? Thanks in advance L.

  • Awk appears to disconnect my DB2 session when piping

    - by greggannicott
    Hello. I'm attempting to run the following command in Korn Shell (ksh): set -A INDEXES `db2 "describe indexes for table ${TABSCHEMA}.${TABNAME} show detail" | awk '{print $1"."$2}'` What I'm attempting to achieve is place a list of the indexes over a particular table into an array which I can later iterate through. The problem is, when I run the above command the contents of the array starts with the error message of 'SQL1024N' (which is telling me that the database connection does not exist). However, if I remove the 'awk' at the end of the statement as so: set -A INDEXES `db2 "describe indexes for table ${TABSCHEMA}.${TABNAME} show detail"` it works just fine (well, to the extent its returning data. Obviously without the awk I'm not capturing the correct data). Does anyone know why the awk is having this affect? I appreciate there is more than one way to get this data, but it baffles me as to why this is happening. Thanks in advance. Greg.

  • Google App Engine - Is os.environ reset between requests?

    - by Ian Charnas
    Hello I can't think of a way to test this and was hoping someone here knew the answer... I'm storing some request-specific data in os.environ, and was wondering if that data was going to leak to other requests. Does anyone know? Yes I realize that it's normal to use request.environ for this, and usually I do, but I want to store the currently authorized user ID (I'm using custom auth, not GAE auth) inside os.environ so that the models know the currently logged in user (remember, they don't have access to request.environ) without me having to pass the request object to just about every single model method. any help would be greatly appreciated Ian

  • How to make 2 executables communicate in both directions in Windows

    - by user302099
    Hello. I have 2 Windows console applications, reading from standard input and writing to standard output. I'd like to assume I don't have the source code to any of them (actually I usually have the source code of one of them). I want to direct the standard output of one to the standard input of the other and vice versa, thus allowing communication (the goal is to allow two programs playing a certain game to play one against the other). How can this be done? I'm willing to do some C/C++ programming or anything else required. Oren.

  • Using PowerShell class to invoke a "[namespace.class]::method" style command

    - by Marco
    Hello, I created a powershell object via .net to invoke commands. When I invoke normal commands like 'Get-Process' I had no problems: ps.AddCommand("Get-Process").AddParameter(...).Invoke() but I'm not able to invoke a .net method with the syntax "[namespace.class]::method", just to make an example to invoke [System.IO.File]::Exists("c:\boo.txt"). I tried with ps.AddCommand("[System.IO.File]::Exists(\"c:\\boo.txt\")").Invoke() ps.AddCommand("[System.IO.File]::Exists").AddArgument("c:\\boo.txt").Invoke() and some others. It always throws an exception which says that the command specified is not recognized. There is a way to invoke that type of command? Thanks

  • Config file format

    - by Felics
    Hello, does anyone knows a file format for configuration files easy to read by humans? I want to have something like tag = value where value may be: String Number(int or float) Boolean(true/false) Array(of String values, Number values, Boolean values) Another structure(it will be more clear what I mean in the fallowing example) Now I use something like this: IntTag=1 FloatTag=1.1 StringTag="a string" BoolTag=true ArrayTag1=[1 2 3] ArrayTag2=[1.1 2.1 3.1] ArrayTag3=["str1" "str2" "str3"] StructTag= { NestedTag1=1 NestedTag2="str1" } and so on. Parsing is easy but for large files I find it hard to read/edit in text editors. I don't like xml for the same reason, it's hard to read. INI does not support nesting and I want to be able to nest tags. I also don't want a complicated format because I will use limited kind of values as I mentioned above. Thanks for any help.

  • Counting unique values in a column with a shell script

    - by Lilly Tooner
    Hello. I have a tab delimited file with 5 columns and need to retrieve a count of just the number of unique lines from column 2. I would normally do this with Perl/Python but I am forced to use the shell for this one. I have successfully in the past used *nix uniq function piped to wc but it looks like I am going to have to use awk in here. Any advice would be greatly appreciated. (I have asked a similar question previously about column checks using awk but this is a little different and I wanted to separate it so if someone in the future has this question this will be here) Many many thanks!

  • Android -- How to post app rating/comments to Market from within app?

    - by borg17of20
    Hello all, This is a simple question. Is there a way to allow users to enter in a comment and or rating for my app from directly within my app and have that data posted back to the Android Market? If so, what would the code for that look like if I used an EditText view to allow user input? If not, then is my only other option directly linking to my app in the Market (i.e. the user clicks the link in my app, or a button, and the Market app launches with my app page displayed)? For example: view.setOnClickListener( new OnClickListener(){ public void onClick(View v) { startActivity( new Intent( Intent.ACTION_VIEW, Uri.parse("market://details?id=packagename") ) ); } } *where "packagename" is replaced by my app's package name from the manifest. Thanks.

  • App.config path not correctly interpreted by ASP.NET Application

    - by seragu05
    Hello everyone ! I'm working on a very old project (2000) in VB6 which was "modernized" and upgraded to VB.NET 3.5. I've centralized every old INI configuration file into one MainApp.config, which is referenced by the app.config of every component. There's an VB ASP.NET website in the solution, which uses DLL components, which are looking into app.config for parameters like, say, error log directory, etc. I've deployed the site on my dev. server (Windows 2008 Server w/ IIS 7.0) into the D:\WebSite\ directory. Problem: When running the site, an error occurs. A DLL is looking into app.config for the parameter RepertoireErreur which has the value .\Erreurs\ Instead of returning D:\WebSite\Erreurs\ it returns c:\windows\system32\inetsrv\.\Erreurs\ which doesn't contain the Erreurs directory. Boom. Error. Does anyone have ever encountered the same problem ? Is there a solution ? Thanks,

  • Embedded Lua on iPhone. What's new and what does it mean?

    - by John Smith
    Apparently Apple has changed some term in the agreement again. From http://www.appleoutsider.com/2010/06/10/hello-lua/ section 3.3.2 is now Unless otherwise approved by Apple in writing, no interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). Notwithstanding the foregoing, with Apple’s prior written consent, an Application may use embedded interpreted code in a limited way if such use is solely for providing minor features or functionality that are consistent with the intended and advertised purpose of the Application. instead of the original No interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). I am more interested in embedding Lua, but other people have other embeddings they want to make. I am wondering how you ask for permission, and what they mean by the terms "minor features" and "consistent" and how will Apple interpret this section? It seems to have enough loopholes to drive a real firetruck through.

  • C++ constant reference lifetime

    - by aaa
    hello I have code that looks like this: class T {}; class container { const T &first, T &second; container(const T&first, const T & second); }; class adapter : T {}; container(adapter(), adapter()); I thought lifetime of constant reference would be lifetime of container. However, it appears otherwise, adapter object is destroyed after container is created, leading dangling reference. What is the correct lifetime? how to correctly implement binding temporary object to class member reference? Thanks

  • Silverlight - Timeout Issue

    - by user70192
    Hello, I have a Silverlight 3 application that is querying a large dataset. This query is taking over one minute. After approx. one minute into the attempt, an error is getting logged into the event viewer that says: "Membership credential verification failed" Oddly queries that are taking shorter than 1 minute are running successfully. Because of this, I do not believe it is a "credential" issue, unless somehow it is expiring. But how do I set the expiration? I have no idea what else this could be. Thank you,

I've tried a number of selectors along the lines of: (sometimes)#page (# or .)cats (sometimes)ul li(sometimes with class name) EDIT: I've tried the selectors suggested in the wordpress docs. Thanks!

  • Delphi developer switching to C#

    - by Dorin Duminica
    Hello, I'm a Delphiholic for quite some time now and lately I was thinking of learning some C# as well, however I'm kinda' "afraid of the unknown", I've done some simple apps as a test drive for C# and I have to admit that I've liked it, HOWEVER I do not really like the IDE... that being said here's the question that I would appreciate if others who went down this path would answer: As a Delphi developer what are the "main basic" changes from the Delphi language(by basic I mean basic -- utility functions, streams, etc.), I'm used to add "System, Classes, Windows" to uses not "use System.XXX.YYY.ZZZ", I'm trying to make a partial equality in my mind from Delphi to C# until I can see where does Delphi go hand-in-hand with C# and so on... I hope the question is pretty clear, if not, do not hesitate to swear me and I'll try to clarify as well as I can :-)
