  • call_user_function_array() and __construct

    - by John
    I'm working on a simple framework, and I'm having a slight problem. I'd like to use call_user_function_array() to pass parameters to a function. That's fine, except the function I want to pass it to is __construct. I can't create an instance of an object with cufa(), and by instantiating an object, and then using cufa to call that instance's __construct(), I run into problems with a broken class because I'm calling the constructor twice (and one time it's called wrong.)

  • Using a database/index sequential file independently of the Unix distribution

    - by Helper Method
    What I'm planning to do is a) parse a file for some lines matching a regular expression b) store the match in some sort of database / file so I don't have to do the parsing again and again c) call another program passing the matches as arguments While I can imagine how to do a) and c), I'm a little bit unsure about b). The matches are of the form key:attribute1:attribute2:attribute3 where attribute 2 may be optional. I'm thinking of storing the results in a simple database but the problem is the database needs to available on a number of Unix platform for the program to work. Are there any (simple) databases which can be found on any Unix platforms? Or should I use some sort of index-sequential file?

  • Use a different *.config file, depending on IIS application pool .NET version

    - by LeeCambl
    I'm looking or a way to programmatically determine which version of the .NET Framework an application pool is using in IIS, at runtime, and for a website application to then use that information to choose which *.config file it should use. Is it possible? I'm not sure where to begin. Quite a broad question, and I'm open to any method of solving the problem, so fire away! Thanks in advance, you lovely Stack Overflowers!

  • Convert octet string to human readable

    - by Michael Lang
    Using the pysnmp framework i get some values doing a snmp walk. Unfortunately for the oid 1.3.6.1.21.69.1.5.8.1.2 (DOCS-CABLE-DEVICE-MIB) i get a weird result which i cant correctly print here since it contains ascii chars like BEL ACK When doing a repr i get: OctetString('\x07\xd8\t\x17\x03\x184\x00') But the output should look like: 2008-9-23,3:24:52.0 the format is called "DateAndTime". How can i translate the OctetString output to a "human readable" date/time ?

Is it possible to get the really-Full package to install on the desktop that haven't internet at all?

  • Difference between a Deprecated and an Legacy API?

    - by Vaibhav Bajpai
    I was studying the legacy API's in the Java's Collection Framework and I learnt that classes such as Vector and HashTable have been superseded by ArrayList and HashMap. However still they are NOT deprecated, and deemed as legacy when essentially, deprecation is applied to software features that are superseded and should be avoided, so, I am not sure when is a API deemed legacy and when it is deprecated.

  • Do assembly strong names change when new versions of .Net are released?

    - by Ryan Michela
    I'm trying to load an assembly that was installed as part of .Net 3.5 SP1 using Assembly.Load() by referencing its strong name. This works fine on my computer right now, but is it future proof? Will the strong name of core .Net assemblies change when patches are installed or new versions of the .Net framework are released? If so, how can I load an assembly from the GAC without using it's strong name?

  • Robust Way of Selecting All Text in Textbox

    - by Emil
    I'm trying to have the content of the an HTML textbox be selected fully onFocus. I know the simple solution of putting a onfocus="this.select()" on the component but this is not a good solution because if a user double clicks into the area the selection is lost and in browsers like chrome it is rarely working like it should and just reverts into input form. I have searched on Google for a little while and can't find a good solution, most suggestions are of this simple solution. What I would like it is that the selection inside the textbox not change once selected and if possible the user should not be able to edit the content of the textbox, for example if you have used AdSense when you grab code from AdSense the selection never changes and your unable to alter the code in the textbox. Any solutions would be appreciated.

  • Why can't i call Contains method from my array?

    - by xbnevan
    Arrrg!I am running into what i feel is a dumb issue with a simple script i'm writing in powershell. I am invoking a sql command that is calling a stored proc, with the results i put it a array. The results look something like this: Status ProcessStartTime ProcessEndTime ------ ---------------- -------------- Expired May 22 2010 8:31PM May 22 2010 8:32PM What i'm trying to do is if($s.Contains("Expired")) , report failed. Simple...? :( Problem i'm running into is it looks like Contains method is not being loaded as i get an error like this: Method invocation failed because [System.Object[]] doesn't contain a method named 'Contains'. At line:1 char:12 + $s.Contains <<<< ("Expired") + CategoryInfo : InvalidOperation: (Contains:String) [], RuntimeException + FullyQualifiedErrorId : MethodNotFound So, what can i do to stop powershell from unrolling it to string? Actual ps script below - $s = @(Invoke-Sqlcmd -Query "USE DB GO exec Monitor_TEST_ps 'EXPORT_RUN',NULL,20 " ` -ServerInstance "testdb002\testdb_002") if ($s.Contains("Expired")) { Write-Host "Expired found, FAIL." } else { Write-Host "Not found, OK." }

  • How to get parallel behavior in Java Script ?

    - by Biswanath
    More or less I want to execute two functions in parallel. One way as I see is doing through SetTimeOut function. I have not completely gone through the ReactiveExentension, although it looks promising but may be overkill for my needs. Is there any framework which supports parallelism ? My use case is trivial, but I would like to know if anybody heavily needed parallelism in Java Script ? Thanks, Biswanath.

  • Using Git or Mercurial, how would you know when you do a clone or a pull, no one is checking in file

    - by Jian Lin
    Using Git or Mercurial, how would you know when you do a clone or a pull, no one is checking in files (pushing it)? It can be important that: 1) You never know it is in an inconsistent state, so you try for 2 hours trying to debug the code for what's wrong. 2) With all the framework code -- potentially hundreds of files -- if some files are inconsistent with the other, can't the rake db:migrate or script/generate controller cause some damage or inconsistencies to the code base?

  • I created a Python egg!!! Now... what do I do with it?

    I've finally figured out how to create a Python egg and gotten it to work. Now... what do I do with it? How do I use it? How do I ensure that everything was correctly included? (Simple steps please... not just redirection to another site. I've googled, but it's confusing me, and I was hoping someone could explain it in a couple of simple bullet points or sentences.)

  • Downloading game assests to SD card on Android

    - by hgpc
    I'm developing an Android game that has to download some assets to the SD card to keep the size of the app as small as possible. I was thinking of using an uncompressed zip file to bundle all the assets. A requirement from the client is to protect these assets as much as possible. Being part of the apk is considered enough protection, but if I do this the apk size will be enormous. If I just put a zip bundle in the SD card, then anyone can unzip it and explore its contents. Is there a simple way to do this without retorting to horrid DRM? Obviously if someone really wants to check the resources of an Android game, they can. I'm just looking for a simple solution to avoid making this very easy.

  • Can @Inject be made option in JSR 330 (like @Autowire(required=false)?

    - by Eric B.
    Spring's @Autowire can be configured such that Spring will throw an error if no matching autowire candidates are found: @Autowire(required=false) Is there an equivalent JSR-330 annotation? @Inject always fails if there is no matching candidate. Is there any way I can use @Inject but not have the framework fail if no matching types are found? I haven't been able to find any documentation to that extent.

  • Waiting for ServerSocket accept() to put socket into "listen" mode

    - by inazaruk
    I need a simple client-server communication in order to implement unit-test. My steps: Create server thread Wait for server thread to put server socket into listen mode ( serverSocket.accept() ) Create client Make some request, verify responses Basically, I have a problem with step #2. I can't find a way to signal me when server socket is put to "listen" state. An asynchronous call to "accept" will do in this case, but java doesn't support this (it seems to support only asynchronous channels and those are incompatible with "accept()" method according to documentation). Of cause I can put a simple "sleep", but that is not really a solution for production code. So, to summarize, I need to detect when ServerSocket has been put into listen mode without using sleeps and/or polling.
