  • ActionScript 3 Context Menu Per Sprite?

    - by TheDarkIn1978
    is it not possible to have different context menus for different sprites on the stage? i've tried adding a custom context menu to a sprite but it's applied to the entire stage: mySprite.contextMenu = myMenu; then after reading the documentation where it states: You can attach a ContextMenu object to a specific button, movie clip, or text field object, or to an entire movie level. You use the menu property of the Button, MovieClip, or TextField class to do this. ok, so i though i had to write it like: mySprite.menu.contextMenu = myMenu; only to be greeted with a nice migration issue stating that menu is legacy code and to use contextMenu instead. ??? um, thanks for the headsup, documentation. this process would be entirely much more easier if i could extend the ContextMenu, but for some reason it's marked as "final" and can't be extended... i'm sure adobe's reasons for finalizing the context menu class are as good as their reasons for including misleading documentation. thoughts?

  • Is concatenating with an empty string to do a string conversion really that bad?

    - by polygenelubricants
    Let's say I have two char variables, and later on I want to concatenate them into a string. This is how I would do it: char c1, c2; // ... String s = "" + c1 + c2; I've seen people who say that the "" + "trick" is "ugly", etc, and that you should use String.valueOf or Character.toString instead. I prefer this construct because: I prefer using language feature instead of API call if possible In general, isn't the language usually more stable than the API? If language feature only hides API call, then even stronger reason to prefer it! More abstract! Hiding is good! I like that the c1 and c2 are visually on the same level String.valueOf(c1) + c2 suggests something is special about c1 It's shorter. Is there really a good argument why String.valueOf or Character.toString is preferrable to "" +? Trivia: in java.lang.AssertionError, the following line appears 7 times, each with a different type: this("" + detailMessage);

  • Send and receive data trough the power network

    - by luvieere
    I'm not interested in a hardware solution, I want to know about software that may "read" modulated signal received trough the power supply - some sort of a low-level driver that would access the power signal in a convenient place and demodulate it. Is there a way to receive signal from the computer's power supply? I'm interested in an API or library that would allow the computer to be seen as a node in a Power Line Communication network and receive data directly through the power cable, without the need for a converter. Is there any active research in this field? Edit: There is software that reads monitors and displays internal component voltages - DC voltage after being converted and filtered by the power supply - now I need is a method of data encoding that would be invariant to conversion and filtering, the original signal embedded in AC being present in some form within the converted DC signal.

  • When to use Hibernate?

    - by Ramo
    Hi All, I was asked in an interview this question so I answered with the following: -Better Performance: - Efficient queries. - 1st and 2nd level caching. - Good caching gives better scalability. - Good Database Portability: - Changing the DB is as easy as changing the dialect configuration. - Increased Developer Productivity: - Think only in object terms not in query language terms. But I also feel that systems fall in one of the below categories, and Hibernate may not be suited for all these cases, I'm interested in your thoughts about this, do you agree with me? please let me know when would use HB in the following case and why. Write Only Systems: Read Only Systems: Write Mostly Systems: Read Mostly Systems: Regards Ramo

  • Why There is a difference between assembly languages like Windows, Linux ?

    - by mcaaltuntas
    I am relatively new to all this low level stuff,assembly language.. and want to learn more detail. Why there is a difference between Linux, Windows Assembly languages? As I understand when I compile a C code Operating system does not really produce pure machine or assembly code, it produces OS dependent binary code.But why ? For example when I use a x86 system, CPU only understands x86 ASM am I right?.So Why we dont write pure x86 assembly code and why there are different assembly variations based on Operating system? If we would write pure ASM or OS produce pure ASM there wouldn't be binary compatilibty issues between Operating systems or Not ? I am really wondering all reasons behind them. Any detailed answer, article, book would be great. Thanks.

  • filter log file by defining regexes

    - by fmpdmb
    I have some HUGE log files (50Mb; ~500K lines) I need to start filtering some of the crap out of. The log files are being produced using log4j and have the basic pattern of: [log-level] date-time class etc, etc log-message I'm looking for a way that I can identify a regex start and regex end (or something similar) that will filter out the matching entries from the file so I can more easily wade through these massive files. I'm sure I could write a java program to accomplish this task, but I thought I'd ask the community before going down that path. Thanks in advance.

  • Oracle Triggers Query..

    - by AGeek
    Lets consider a Table STUD and a ROW-Level TRIGGER is implemented over INSERT query.. My scenario goes like this, whenever a row is inserted, a trigger is fired and it should access some script file which is placed in the hard disk, and ultimately should print the result. So, is this thing is possible? and if yes, then this thing should exist in dynamic form, i.e. if we change the content of script file, then the oracle should reflect those changes as well. I have tried doing this for java using External Procedures, but doesn't feel that much satisfied with the result that i wanted. Kindly give your point-of-view for this kind of scenario and ways that this can be implemented.

  • list python package dependencies without loading them ?

    - by Denis
    Say that python package A requires B, C and D; is there a way to list A → B C D without loading them ? Requires in the metadata (yolk -M A) are often incomplete, grr. One can download A.tar / A.egg, then look through A/setup.py, but some of those are pretty gory. (I'd have thought that getting at least first-level dependencies could be mechanized; even a 98 % solution would be better than avalanching downloads.)

  • Pros and Cons of Proprietary Software

    - by Jon Purdy
    Proprietary software is about as good as open-source software. There are so many problems with proprietary technologies, however, that I'm beginning to think it's best to avoid them: The software will only be maintained as long as the company exists (and profits). The level of security of the application is as unknowable as the source code. Alterations and derivative works, however necessary and beneficial, are disallowed. I simply don't see any point in even learning to use such systems as those created by Microsoft and Apple. Of course I don't pretend that ignorance is the superior option: one has to have a certain working knowledge simply because of the ubiquity of these things. I just don't see any reason why, as an independent developer, I should ever consider it a remotely good idea to actually use them. So that's the question, or discussion topic, or what have you: In what ways do developers benefit at all from using closed-source development software?

  • Function chaining depending on boolean result

    - by Markive
    This is just an efficiency question really.. I'm interested to know if there is a more efficient or logical way that people use to handle this sort of scenario. In my asp.net application I am running a script to generate a new project my code at the top level looks like this: Dim ok As Boolean = True ok = createFolderStructure() If ok Then ok = createMDB() If ok Then ok = createProjectConfig() If ok Then ok = updateCompanyConfig() I create a boolean and each function returns a boolean result, the next function in this chain will only run if the previous one was successful. I do this because an asp.net application will continue to run through the page life cycle unless there is an unhandled exception and I don't want my whole application to be screwed up if something in the chain goes wrong (there is a lot of copying and deleting of files etc.. in this example). I was just wondering how other people handle this scenario? the vb.net single line if statement is quite succinct but I'm wondering if there is a better way?

  • zChaff not showing output

    - by pns
    Hello, So I downloaded the latest version of zChaff (2007), and was trying out some very simple SAT problems. But zChaff does not output the solution (variable assignments). A very simple example input: p cnf 2 2 1 2 0 1 -2 0 And what I get: c 2 Clauses are true, Verify Solution successful. Instance Satisfiable 1 -2 Random Seed Used 0 Max Decision Level 1 Num. of Decisions 2 ( Stack + Vsids + Shrinking Decisions ) 0 + 1 + 0 Original Num Variables 2 Original Num Clauses 2 Original Num Literals 4 Added Conflict Clauses 0 Num of Shrinkings 0 Deleted Conflict Clauses 0 Deleted Clauses 0 Added Conflict Literals 0 Deleted (Total) Literals 0 Number of Implication 2 Total Run Time 5.1e-05 RESULT: SAT I can see the 1 -2 on the left of "Random Seed Used", but shouldn't this be outputing the variable assignments as "v ..." ? Thanks

  • What is the most elegant way to access current_user from the models? or why is it a bad idea?

    - by TheLindyHop
    So, I've implemented some permissions between my users and the objects the users modify.. and I would like to lessen the coupling between the views/controllers with the models (calling said permissions). To do that, I had an idea: Implementing some of the permission functionality in the before_save / before_create / before_destroy callbacks. But since the permissions are tied to users (current_user.can_do_whatever?), I didn't know what to do. This idea may even increase coupling, as current_user is specifically controller-level. The reason why I initially wanted to do this is: All over my controllers, I'm having to check if a user has the ability to save / create / destroy. So, why not just return false upon save / create / destroy like rails' .save already does, and add an error to the model object and return false, just like rails' validations? Idk, is this good or bad? is there a better way to do this?

  • Multiple levels of 'collection.defaultdict' in Python

    - by Morlock
    Thanks to some great folks on SO, I discovered the possibilities offered by collections.defaultdict, notably in readability and speed. I have put them to use with success. Now I would like to implement three levels of dictionaries, the two top ones being defaultdict and the lowest one being int. I don't find the appropriate way to do this. Here is my attempt: from collections import defaultdict d = defaultdict(defaultdict) a = [("key1", {"a1":22, "a2":33}), ("key2", {"a1":32, "a2":55}), ("key3", {"a1":43, "a2":44})] for i in a: d[i[0]] = i[1] Now this works, but the following, which is the desired behavior, doesn't: d["key4"]["a1"] + 1 I suspect that I should have declared somewhere that the second level defaultdict is of type int, but I didn't find where or how to do so. The reason I am using defaultdict in the first place is to avoid having to initialize the dictionary for each new key. Any more elegant suggestion? Thanks pythoneers!

  • How to prevent command/script from changing global environment

    - by guillermooo
    I need to run scriptblocks/scripts from the current top-level shell and I want them to leave the global environment unmodified. So far, I've only been able to think of the following possibilities: powershell -file <script> powershell -noprofile -command <scriptblock> The problem is, that they are very slow. For instance, I would like to be able to do: mkdir newdir cd newdir $env:NEW_VAR = 100 ni -item f 'newfile.txt' ...so that my shell's working dir wouldn't change and $env:NEW_VAR wouldn't be set in the global environment. Are there any more alternatives to accomplish this?

  • Security for web services only used from a Silverlight application?

    - by Lasse V. Karlsen
    I have googled a bit for how I should handle security in a web service application when the application is basically the data repository for a Silverlight application, but have gotten inconclusive results. The Silverlight application is not supposed to have its own user authentication, since it will be reachable only through a web application that the user have already authenticated to get into. As such, I was thinking I could simply add a parameter to the SL application that is a cookie-type value, with a certain lifetime, linked to the user in the database. The SL application would then have to pass this value alongside other parameters to the web services. Since the web service is hopefully going to be a generic web service endpoint, few methods, adding an extra parameter at this level will not be a problem. But, am I supposed to roll this system on my own? It sounds to me as this isn't exactly new features that nobody has considered before, so what are my options?

  • how does teamviewer find my computer even if my comp. behind of the firewall and firewall isn't conf

    - by uzay95
    Did you use teamviewer? (comic question i know... Who doesn't use it?) Do you have any idea how does teamviewer make connection even if i am behind the router, firewall, switch and my local firewall..? I'm trying to imagine a connection that is between remote machinge and my computer. Remote machine is sending the packets (and its header (for instance, destination IP, message body)) to me but it only knows my id number(which is given by my local teamviewer application). And this packets are reaching to my computer even if there is a juniper firewall (and also my windows firewall). What kind a message body is recieving by computer? (of course it is not like xml, text, html, excel :) Do you have any idea? PS. Please share your knowledge like you are explaining to beginner level user.

  • Using variables in Tasker

    - by Waza_Be
    I am trying to create a Tasker plugin. Everything is fine, and works pretty well. I can configure a String to be sent in my app by using EditActivity and this code, following the examples: resultIntent.putExtra(com.twofortyfouram.locale.Intent.EXTRA_BUNDLE,PluginBundleManager.generateBundle(getApplicationContext(),message)); resultIntent.putExtra(com.twofortyfouram.locale.Intent.EXTRA_STRING_BLURB,generateBlurb(getApplicationContext(), message)); setResult(RESULT_OK, resultIntent); The problem comes when I want to use this code to get the battery level for instance, so I added: resultIntent.putExtra("net.dinglisch.android.tasker.extras.VARIABLE_REPLACE_KEYS",com.twofortyfouram.locale.Intent.EXTRA_STRING_BLURB); but the app is not working and I get a string %BATT as the result, the variable is not replaced... As I haven't found any example, I would be pleased to get some help to make it work.

Redirect to below: https://blogurl.com/content/news/2014-08-19/post-3451/mt-preview-33e2742af1eb.php I basically want to insert /content/ after https://blogurl.com and so far I have rewrite ^(.*)$ /content/ break; But my issue is my CMS sits on the same directory level https://blogurl.com/mt/admin and if I simply apply the rewrite above my CMS address would move too. How could I prevent this.

  • Many-to-one relationship in SQLAlchemy

    - by Arrieta
    This is a beginner-level question. I have a catalog of mtypes: mtype_id name 1 'mtype1' 2 'mtype2' [etc] and a catalog of Objects, which must have an associated mtype: obj_id mtype_id name 1 1 'obj1' 2 1 'obj2' 3 2 'obj3' [etc] I am trying to do this in SQLAlchemy by creating the following schemas: mtypes_table = Table('mtypes', metadata, Column('mtype_id', Integer, primary_key=True), Column('name', String(50), nullable=False, unique=True), ) objs_table = Table('objects', metadata, Column('obj_id', Integer, primary_key=True), Column('mtype_id', None, ForeignKey('mtypes.mtype_id')), Column('name', String(50), nullable=False, unique=True), ) mapper(MType, mtypes_table) mapper(MyObject, objs_table, properties={'mtype':Relationship(MType, backref='objs', cascade="all, delete-orphan")} ) When I try to add a simple element like: mtype1 = MType('mtype1') obj1 = MyObject('obj1') obj1.mtype=mtype1 session.add(obj1) I get the error: AttributeError: 'NoneType' object has no attribute 'cascade_iterator' Any ideas?

  • Problem with acceding in DOM with jQuery

    - by Tristan
    Hello, I changed the tree of my JSON-P output, and i cannot access to my object DOM anymore : Here's my output : jsonp1271634374310( {"Inter-Medias": {"name":"Inter-Medias","idGSP":"14","average":"80","services":"8.86"} }); And here's my jQuery script : success: function(data, textStatus, XMLHttpRequest){ widget = data.name; widget += data.average ; .... I know one level is missing, but if I try to do : data.Inter-Medias.name or data.name.name it's still not working. Any idea please ? I will have case where i'll have multiple Ojbect, so i want to display all of them, how to do that ? for (i=0;i < data.length;i++) Does it look right ? Bonus question : i understand function(data, textStatus, XMLHttpRequest) that in case of success this function is triggered, the data is what the script recieved from his request, but i have no idea what textStatus or XMLHttpRequest are here too and why ?! Thank you.

  • .NET Forms Abstraction for WPF, Silverlight, Winforms, WebForms, etc...

    - by tyndall
    Anyone know of a project(s) that seek to abstract form definitions on level higher than WPF, Silverlight, Winforms, WebForms, etc... I'm working on a project where we are fixing up 16 somewhat simple WebForms. But we may convert (and probably will convert to WPF or Silverlight 3 to 4 months from now. I'd rather define these forms once and be done with it. I'm willing to write a small DSL to help define forms, subforms, validation, links, and popups. I'm only looking to solve this for 80% or 90% of the forms. Four are very complicated and I'm willing to hand code these. I guess I'm looking for something like what XUL had hoped to be.
