  • foo and _foo - about variables inside a class

    - by kame
    class ClassName(object): """ """ def __init__(self, foo, bar): """ """ self.foo = foo # read-write property self.bar = bar # simple attribute def _set_foo(self, value): self._foo = value def _get_foo(self): return self._foo foo = property(_get_foo, _set_foo) a = ClassName(1,2) #a._set_foo(3) print a._get_foo() When I print a._get_foo() the function _get_foo prints the variable self._foo . But where does it come from? self._foo and self.foo are different, aren't they?

  • Passing variables from SQL proceedure to PHP

    - by Sam Corbet
    I am trying to create an sql proceedure that will return the results back to the php page. I want to be able to call the procedure as follows from the php call procedure_name($var1) which will run this script: -- --------------------------------------------------------------------------------- -- pUIGetCliStmtGenFlag -- -- This procedure returns the status of the Trading Period: -- -- --------------------------------------------------------------------------------- drop procedure if exists pUIGetCliStmtGenFlag; delimiter // create procedure pUIGetCliStmtGenFlag( IN pTradingPeriodMonth DATE ) MODIFIES SQL DATA COMMENT 'Checks if the TP has been closed' begin SELECT trading_period_month, dt_end, amt_traded_system_ccy FROM ca_trading_period WHERE trading_period_month=$var1 -- If amt_traded_system_ccy is NULL give the TP an open status otherwise mark as closed IF amt_traded_system_ccy is NULL $tpstatus='open' ELSE $tpstatus='closed' end; // delimiter ; I then want to be able to use $tpstatus in the rest of the php script. I know this is simple but this is completely new to me and I cant find the correct method

  • Creating PHP strings using other variables...works manually, can't figure out how automatically

    - by Matt
    Hello, I'm trying to get a variable to be formed automatically using data pulled from a mysql database. I know the data is being pulled from the database in some form resembling its original form, but that data does not act the same as data that is manually typed and assigned to a string. For example, if a cell in a mysql table says... I said "goodbye" before I left. She also said "goodbye." ...and I manually copy/paste it and add the necessary escapes... $string1 = " I said \"goodbye\" before I left. She also said \"goodbye.\" "; ...that does not equal... $string1 = $mysqlResultArray['specificCellWithQuoteShownAbove'] Interestingly, if I echo both versions of $string1 and view the output, they appear to be exactly the same. But they do not function the same when put through various functions I've created. The functions only work if I do the manual copy/paste method--which is not what I want, obviously. I'm not sure if it has to do with the line breaks or the escapes--or some combination of the two. But while both strings are superficially the same, they are apparently functionally different and I don't know why. So how can I create $string1 without manually copy/pasting the contents from the mysql entry and instead querying for the data and assigning it to $string1 in such a way that it's exactly functionally equivalent as the manual copy/pasted string?

  • How to use Mysql variables with Hibernate ?

    - by Jerome C.
    Hello, I need to use a native sql query in Hibernate with use of variable. But hibernate throws an error saying: Space is not allowed after parameter prefix So there is a conflict with the := mysql variable assignment and hibernate variable assignment. Here is my sql query: SET @rank:=0; UPDATE Rank SET rank_Level=@rank:=@rank+1 ORDER BY Level; I can't use a stored procedure because my sql query is dynamically generated ('Level' can be 'int' or 'force'...) How can I do this ? thanks

  • Javascript Anonymous Functions and Global Variables

    - by Jonathan Swift
    I thought I would try and be clever and create a Wait function of my own (I realise there are other ways to do this). So I wrote: var interval_id; var countdowntimer = 0; function Wait(wait_interval) { countdowntimer = wait_interval; interval_id = setInterval(function() { --countdowntimer <=0 ? clearInterval(interval_id) : null; }, 1000); do {} while (countdowntimer >= 0); } // Wait a bit: 5 secs Wait(5); This all works, except for the infinite looping. Upon inspection, if I take the While loop out, the anonymous function is entered 5 times, as expected. So clearly the global variable countdowntimer is decremented. However, if I check the value of countdowntimer, in the While loop, it never goes down. This is despite the fact that the anonymous function is being called whilst in the While loop! Clearly, somehow, there are two values of countdowntimer floating around, but why?

    Hello friends! This is the script I am using to display an accordion in my Joomla site: <?php defined('JPATH_BASE') or die(); gantry_import('core.gantryfeature'); class GantryFeatureAccordion extends GantryFeature { var $_feature_name = 'accordion'; function init() { global $gantry; if ($this->get('enabled')) { $gantry->addScript('accordion.js'); $gantry->addInlineScript($this->_accordion()); } } function render($position="") { ob_start(); ?> <div id="accordion"> <dl> <?php foreach (glob("templates/rt_gantry_j15/features/accordion/*.php") as $filename) {include($filename);} ?> </dl> </div> <?php return ob_get_clean(); } function _accordion() { global $gantry; $js = " jQuery.noConflict(); (function($){ $(document).ready(function () { $('#accordion').easyAccordion({ slideNum: true, autoStart: true, slideInterval: 4000 }); }); })(jQuery); "; return $js; } } I want to call these three values in the templateDetails.XML file as a user input. slideNum: true, autoStart: true, slideInterval: 4000 Like this in the templateDetails.xml file: <param name="accordion" type="chain" label="ACCORDION" description="ACCORDION_DESC"> <param name="slideNum" type="text" default="true" label="Offset Y" class="text-short" /> <param name="autoStart" type="text" default="true" label="Offset Y" class="text-short" /> <param name="autoStart" type="text" default="4000" label="Offset Y" class="text-short" /> </param> How can I do so? What will be the exact syntax for the same. I am very new to programming ans specially to JavaScript. Kindly help.

  • Can't access variables from dynamically loaded javascript

    - by Menno
    I'm using a fairly simple system to load javascript dynamically: include = function (url) { var e = document.createElement("script"); e.src = url; e.type="text/javascript"; document.getElementsByTagName("head")[0].appendChild(e); }; Let's say I have a file test.js which has the following contents: var foo = 4; Now, in my original script, I want to use include(test.js); console.log(foo); However, I get a 'foo has not been defined' error on this. I'm guessing it has to do with the dynamic script being included as the last child of the <head> tag. How can I get this to work?

  • java objects, shared variables

    - by raven
    hello, I have a simple question here. If I declare a variable inside an object which was made [declared] in the main class, like this: public static int number; ( usually I declare it like this : private int number; ) can it be used in a different object which was also made [declared] in the main class? btw I do not care about security atm, I just want to make something work, don't care about protection)

Is there any way to do it?

  • problem in variables in jquery

    - by Alvin
    Hi, I don't understand why I'm not getting the message as "username already exits" if type the username which is already in database. If the username in a server, then it is returning the value as "1" otherwise empty, and despite of successfully getting the value from the server based on username is present or not, and assigning the value to variable "x", I'm unable to get message when I pass already exist username. May I know? $(document).ready(pageInit); function pageInit() { $('#1').bind('blur',go); } function go() { var value = $('#1').val(); var x = 0; $.post('just.do',{username:value},function(data){ x = data; } ); if(x) { $('#para').show(); $('#para').html("Username already exits"); return false; } else { $('#para').hide(); return true; } }; EDIT: This is what I'm doing in post request in servlets: String user1 = request.getParameter("username"); if(user != null) { String query = "Select * from users where user_name="+"\""+user+"\""; b = db.doExecuteQuery(stmt,query); if(b) { out.write("1"); } }

  • Substituting variables in a loop?

    - by jksl
    I am trying to write a loop in R but I think the nomenclature is not correct as it does not create the new objects, here is a simplified example of what I am trying to do: for i in (1:8) { List_i <-List colsToGrab_i <-grep(predefinedRegex_i, colnames(List_i$table)) List_i$table <- List_i$table[,predefinedRegex_i] } I have created 'predefinedRegex'es 1:8 which the grep should use to search The loop creates an object called "List_i" and then fails to find "predefinedRegex_i". I have tried putting quotes around the "i" and $ in front of the i but these do not work. Any help much appreciated. Thank you.

  • 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.

  • Using variables within Attributes in C#

    - by tehp
    We have some Well-Attributed DB code, like so: [Display(Name = "Phone Number")] public string Phone { get; set; } Since it is quite generic we'd like to use it again, but with a different string in the Name part of the attribute. Since it's an attribute it seems to want things to be const, so we tried: const string AddressType = "Student "; [Display(Name = AddressType + "Phone Number")] public string Phone { get; set; } This seems to work alright, except that having a const string means we can't overwrite it in any base classes, thereby removing the functionality that we originally were intending to add, and exposing my question: Is there a way to use some sort of variable inside of an attribute so that we can inherit and keep the attribute decorations?

  • ExpandEnvironmentStrings Not Expanding My Variables

    - by Adam Driscoll
    I have a process under the Run key in the registry. It is trying to access an environment variable that I have defined in a previous session. I'm using ExpandEnvironmentStrings to expand the variable within a path. The environment variable is a user profile variable. When I run my process on the command line it does not expand as well. If I call 'set' I can see the variable. Some code... CString strPath = "\\\\server\\%share%" TCHAR cOutputPath[32000]; DWORD result = ExpandEnvironmentStrings((LPSTR)&strPath, (LPSTR)&cOutputPath, _tcslen(strPath) + 1); if ( !result ) { int lastError = GetLastError(); pLog->Log(_T( "Failed to expand environment strings. GetLastError=%d"),1, lastError); } When debugging Output path is exactly the same as Path. No error code is returned. What is goin on?

  • global variables doesn't change value in Javascript

    - by user1856906
    My project is composed by 2 html pages: 1)index.html, wich contains the login and the registration form. 2)user_logged.html, wich contains all the features of a logged user. Now, what I want to do is a control if the user is really logged, to avoid the case where a user paste a url in the browser and can see the pages of another user. hours as now, if a user paste this url in the browser: www.user_loggato.html?user=x#profile is as if logged in as user x and this is not nice. My html pages both use js files that contains scripts. I decided to create a global variable called logged inizialized to false and change the variable to true when the login is succesfull. The problem is that the variable, remains false. here is the code: var logged=false; (write in the file a.js) while in the file b.js I have: function login() { //if succesfull logged=true; window.location.href = "user_loggato.html?user="+ JSON.parse(str).username + #profilo"; Now with some alerts I found that my variable logged is always false. Why? if I have not explained well or if there is not some information in order to respond to my question let me know.

  • Accessing Variables in Javascript using .length

    - by CoV
    Hey all, I'm pretty new to Javascript, so forgive me if this is a simple question. I'm trying to access the length of a set of checkboxes in a form using Javascript. However, I need to be able to change the "name" field of the checkboxes to check several different sets of them. Right now, my sample code looks like: var set = "set" + x; totalLength = optionBoxes.set.length; The variable x is being incremented by a for loop that wraps the whole thing and the name of the checkbox sets that I'm trying to access are set0, set1, set2, etc. Thanks. Edit: small typo fixes
