• How do I Reload Ajax Call Parameters without Reloading the webpage

  - by Snowright

  I'm working with Extjs 2.2.1 with Alfresco 3.2 enterprise. I would like to update the ticket that handles authentication to the alfresco server on components that have been loaded during login. This ticket expires after a set time and this is why I will need to update the ticket. Options that do not seem viable for me(but please let me know if I'm wrong): Reload the components to reload the call parameters - I can't do this because it resets whatever the user was previously working on (ie. Tree panel gets reloaded, grid filters reset, etc). The actual webpage never reloads as everything uses ajax calls to update things on the page. Create a global variable that stores the ticket and attach it as a call parameter with any ajax calls - Any components that were loaded during login will still use the original ticket to make calls to the server.

• Environment Variables in C

  - by tpar44

  I know this type of question has been asked a lot but none of the answers seem to help. I set an environment variable through setenv() function call in Ubuntu Linux. However, the program doesn't seem use this environment variables. If I use getenv() it gets the correct value but the output to the program is wrong. However, when I use export BLOCKSIZE=512 in the shell, the output to the program is correct. I am not spawning different processes from the program. Below is only a code snippet of what I am doing, it is not my whole program. Is there any reason for this?

• JQuery post to php

  - by RussP

  Why is it that I can never get JQuery serialize to work properly. I guess I must be missing something. I can serialize a form data and it shows in an alert: var forminfo = $j('#frmuserinfo').serialize(); alert(forminfo); I then post to my PHP page thus: $j.ajax({ type: "POST", url: "cv-user-process.php", data: "forminfo="+forminfo, cache: false, complete: function(data) { } }); But WHENEVER (not the first time) I try to insert/update the data in the DB I only ever get 1 varaible passed: Here is my PHP script: $testit = mysql_query("UPDATE cv_usersmeta SET inputtest='".$_POST['forminfo']."' WHERE user='X'"); the data passed only ever gets the first variable. why? I think it is more the way I deal with the php but it drives me nuts and always takes me far too long to find where I am going wrong.

• Execute a method less times possible - PHP

  - by serhio

  I have a site in multiple languages. I have a method that returns me the today currencies in a array. I display that currencies in a table then. // --- en/index.php <?php include_once "../exchangeRates.php"; $currencies = ReadExchangeRates(); // --- fr/index.php <?php include_once "../exchangeRates.php"; $currencies = ReadExchangeRates(); ... // somewhere in the page <td><?php echo $currencies["eur"]["today"]; ?></td> So, every time I load, en/ or fr/ or other language, I request the exchange rates from a external site. Can I optimize this behavior (reading once per day or session)? maybe to store a global variable and check the update date?

• 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.

• What is the best way to declare a property?

  - by Simon

  Hi. We declare properties using the @property keyword and synthesize it in the implementation file. My question is, What if I declare a property using the @property keyword and also declare a variable in the interface block with the same name? For example, consider the following code, Interface: @interface myClass : NSObject { NSString *myClass_name; // LINE 1 } @property(nonatomic, retain) NSString *myClass_name; // LINE 2 @end Implementation: @implementation myClass @synthesize myClass_name // LINE 3 @end Declaring myClass_name in LINE 1 will make any problem? Like any reference problem or any unnecessary memory consumption problem?

• How do I send the ckeditor config using jQuery service?

  - by syn4k

  My service is built and it is sending the config variable to my js file: [['SpellChecker','-','Undo','Redo','-','Bold','Italic','Underline','NumberedList','BulletedList']] The above is assigned to my javascript like so: var config = "<?= stripslashes($_REQUEST['config']) ?>"; I can alert out the config just fine: console.log(config) does send back the correct data... However, I get an error thrown in my console!: v is undefined [Break On This Error] var u=n.toolbox.toolbars,v=n.config.to...aximize','ShowBlocks','-','About']]; If I comment out the config: //CKEDITOR.config.toolbar = config; everything works fine but the configuration doesn't exist, of course...

• Carrying scope of "this" into inner functions

  - by Matrym

  How can I extend the scope of this inward? I thought reassigning a higher scoped variable would do the trick... what am I doing wrong? http://jsfiddle.net/8bqXM/ function Player(configs) { this.opts = { playerID: "cSurf" }; configs = $.extend(this.opts, configs); var the = this; this.init = function(){ var $player = $("#" + the.configs.playerID); alert($player.attr("id")); } } var cSurf = new Player(); $(document).ready(function(){ cSurf.init(); });

• Instantiating class by string using PHP 5.3 namespaces

  - by Kevin

  I can't get around an issue instantiating a new class by using a string variable and PHP 5.3. namespaces. For example, this works; $class = 'Reflection'; $object = new $class(); However, this does not; $class = '\Application\Log\MyClass'; $object = new $class(); A fatal error gets thrown stating the class cannot be found. However it obviously can be instantiated if using the FQN i.e.; $object = new \Application\Log\MyClass; I've found this to be aparrent on PHP 5.3.2-1 but not not in later versions. Is there a work around for this?

• Equal height divs with footer always at bottom of tallest div

  - by nukegara

  I was wondering if this were possible, and if it is the best way to go about this: example image (since I'm not allowed to post pics yet ^^) So, not only does each column have to be of equal height, but each column also has its own individual footer. I saw this post httx://stackoverflow.com/questions/1347366/div-at-bottom-of-window-and-adaptable-height-div (I also can't post more than one link....) - how could I rework this technique to apply to the bottom of the divs and not the bottom of the window? *edit - each column will have content that will constantly change and be of variable height. I'm thinking I could just figure out the equal height columns first, then just absolute position a footer div within those columns. Does its parent div then have to be position: relative?

• Proper programming procedure?

  - by Rob

  I am creating a scoring application which is dependent upon what a user selects at the beginning menu. Example: If a user clicks 18, I want it to base itself off 18 holes of golf. If a user clicks 9, I want it to base itself off 9 holes of golf. Is it better to create a separate class for the code for 9 holes, and then another for 18 holes and then launch whichever depending on what the user selects? Or should I keep everything in 1 file and use a global variable to define different parameters? Still very new to android programming (or programming in general) so not sure of the proper "etiquette" if you will... Also what would be the pro's and con's of doing it either way? (If any) Thanks in advance!

• C++ Typing and OOP child classes

  - by Zack

  I'm a bit confused: If I have a base class A, and a class B which extends A, can a variable of the type A hold a value of the type B and vice versa? If yes, why? Aren't they completely different even if B is derived from A? How about type-safety? If this is possible, what things do I have to mind when taking use of this? How would this work out in terms of performance? Note: Sorry if I asked too many questions, just ignore them and just look out for those "marked" with the list decoration dot :) Also, this is not my homework. I'm a hobby programmer and have skills in scripting languages with OOP, yet I'm relatively new to OOP typing in C++.

• Adding new "columns" to csv data file in Tcl

  - by George

  Hi All, I am dealing with a "large" measurement data, approximately 30K key-value pairs. The measurements have number of iterations. After each iteration a datafile (non-csv) with 30K kay-value pairs is created. I want to somehow creata a csv file of form: Key1,value of iteration1,value of iteration2,... Key2,value of iteration1,value of iteration2,... Key2,value of iteration1,value of iteration2,... ... Now, I was wondering about efficient way of adding each iteration mesurement data as a columns to csv file in Tcl. So, far it seems that in either case I will need to load whole csv file into some variable(array/list) and work on each element by adding new measurement data. This seems somewhat inefficient. Is there another way, perhaps?

• How to assign the value of document.cookie to your browser cookies?

  - by Ricket

  I'm a developer (and therefore a tester) of a website. Our site accepts any JavaScript or HTML from an user but I haven't been successful in explaining the danger of it, as obvious as it is. So I would like to prove it by logging in as my boss to prove to him that there is definitely a real danger here. I think this will put down any of his arguments and let us move onto filtering content like this. (note this question is not about filtering, or other suggestions on JavaScript tricks) I already know how to steal the value of the document.cookie variable with AJAX and a PHP file, but once you have that string of name=value;name=value;..., how do you apply it to your own browser? This is programming related because I am asking about tools which will help me debug my web program.

• AngularJS, changing the data in a view without div disappearing

  - by Jascination

  I'm making a little wizard/survey in AngularJS which loads in data to a variable, $scope.styles. I've set up a plunkr for ease of use here: http://plnkr.co/edit/1S542YE7xlO2P4zyhzu0?p=preview Pretty simple. I show each object to the user in succession, which loads in the pertinent images and displays them for the user. clicking "yes/no" at the bottom of the images it loads in the next gallery. There is a big of lag between the refresh here (Plunkr seems to be loading it quite quickly, but this is not the case on my production server so it's even more noticable) which causes the window size to momentarily be much smaller plus all the content below the ng-repeat jumps to the top of the screen. What's the best way to prevent this from happening? Is CSS the only solution here?

• How to force main Acivity to wait for subactivity in Android?

  - by rmaster

  hi, I am calling a subactivity from main activity. This subactivity should take few numbers from user (i'm using Edit text control to achieve this), save them to static variable in another class and terminate. I want main activity to wait for subactivity but both are just running simultaneously. Even doing sth like that doesn't help: Thread t = new Thread(new Runnable(){ public void run(){ Log.v("==================", "run "+new Date()); startActivityForResult(new Intent(ctx,myCustomSubactivity.class),1); } }); Log.v("==================", "calling run "+new Date()); t.start(); try { t.join(); } catch (InterruptedException e) {Log.v("==================", "can't join");} Log.v("==================", "back from activity "+new Date()); do you know how to force main activity to wait? Thread.wait() method is not supported in Android(program throws error).

• Is there a single query that can update a "sequence number" across multiple groups?

  - by Drarok

  Given a table like below, is there a single-query way to update the table from this: | id | type_id | created_at | sequence | |----|---------|------------|----------| | 1 | 1 | 2010-04-26 | NULL | | 2 | 1 | 2010-04-27 | NULL | | 3 | 2 | 2010-04-28 | NULL | | 4 | 3 | 2010-04-28 | NULL | To this (note that created_at is used for ordering, and sequence is "grouped" by type_id): | id | type_id | created_at | sequence | |----|---------|------------|----------| | 1 | 1 | 2010-04-26 | 1 | | 2 | 1 | 2010-04-27 | 2 | | 3 | 2 | 2010-04-28 | 1 | | 4 | 3 | 2010-04-28 | 1 | I've seen some code before that used an @ variable like the following, that I thought might work: SET @seq = 0; UPDATE `log` SET `sequence` = @seq := @seq + 1 ORDER BY `created_at`; But that obviously doesn't reset the sequence to 1 for each type_id. If there's no single-query way to do this, what's the most efficient way? Data in this table may be deleted, so I'm planning to run a stored procedure after the user is done editing to re-sequence the table.

• Concatenating a Text in front of Individual Database Records with Tcl

  - by DFM

  Hello: In short, currently I am using the following code to pull records from multiple tables in a Sqlite Db and insert them in a single combobox ($SearchBar): set SrchVals1 [db eval {SELECT DISTINCT Stitle From Subcontract Order By Stitle ASC}] set SrchVals2 [db eval {... set SrchVals3 ... set SrchValsALL [concat $SrchVals1 $SrchVals2 $SrchVals3] $SearchBar configure -value $SrchValsAll For the variable "SrchVals1", I am trying to figure out a way to concatenate the text "Sub: " to each individual record in SrchVals1. For example, if SrchVals1 shows the following records in the combobox: First Title Second Title Third Title I would like to concatenate so that the records in the combobox look like this: Sub: First Title Sub: Second Title Sub: Third Title I understand that I might have to use a foreach statement; however, I am having no luck writing one that adds "Sub: " in front of each record, as opposed to one. This seems like something that should be pretty easy, but I cannot seem to figure it out. Does anyone know how I can achieve these results? Thank you, DFM

• How would I initialize these two lists so that modifying one doesn't modify the other?

  - by Brandon

  I'm aware of why this is happening, but is there any way to do this without having to implement ICloneable or a Copy() method? Preferably .net 2.0, but 3.5 is fine if it is necessary. Essentially I'm trying to implement an undo method. In most cases I can just perform the reverse action in the Undo(), but for others that is not possible. So I want to keep two lists. One for the list of items that I will be modifying, and one for the original, unmodified list of items. This way if I need to do an undo, I just delete the modified items and replace them with the originals. Most of the ways I've tried to assign the _originalItems variable doesn't work, so what would I need to do? public MyClass(List<SelectedItems> selectedItems) { _selectedItems = new List<SelectedItems>(selectedItems); _originalItems = ?? }

• passing something from child form to parent

  - by Alan Bennett

  so i have this form and on it is a combo box populated from a database via a SQL method. and i have another form which allows us to maintain the database table etc. so i make a new instance of the second form doing: Form1 frm = new Form2; frm.show(); once i have done what ever i wanted to do on the second form and i close it, i need to somehow trigger an event or something which will refresh the combo box and the code behind it. i was thinking of some onchange or focus event for the whole form, the problem is i have 5 of these combo boxes and running all the SQL again. i also thought of passing somesort of variable thro but then i would still need an event for that. any ideals would be awesome

• Could not find any resources appropriate for the specified culture or the neutral culture.

  - by Captain Comic

  I have created an assembly and later renamed it. Then i started getting runtime errors when calling toolsMenuName = resourceManager.GetString(resourceName); The resourceName variable is "enTools" at runtime. Could not find any resources appropriate for the specified culture or the neutral culture. Make sure "Jfc.TFSAddIn.CommandBar.resources" was correctly embedded or linked into assembly "Jfc.TFSAddIn" at compile time, or that all the satellite assemblies required are loadable and fully signed. The code: string resourceName; ResourceManager resourceManager = new ResourceManager("Jfc.TFSAddIn.CommandBar", Assembly.GetExecutingAssembly()); CultureInfo cultureInfo = new CultureInfo(_applicationObject.LocaleID); if(cultureInfo.TwoLetterISOLanguageName == "zh") { System.Globalization.CultureInfo parentCultureInfo = cultureInfo.Parent; resourceName = String.Concat(parentCultureInfo.Name, "Tools"); } else { resourceName = String.Concat(cultureInfo.TwoLetterISOLanguageName, "Tools"); } // EXCEPTION IS HERE toolsMenuName = resourceManager.GetString(resourceName); I can see the file CommandBar.resx included in the project, i can open it and can see the "enTools" string there.

• Prevent Erroneous Property Assignment

  - by Gordon

  Porting android applications to iphone applications always gives me the following pattern that I accidentally create: - (void) myFunc:(id)prop { self.property = property; } Which instead should be: - (void) myFunc:(id)prop { self.property = prop; } This always causes my program to quietly break because property gets reset to its existing value rather than being set to the new value, 'prop'. I cannot name the parameter 'prop' to 'property' since the compile complains that the parameter masks the instance variables visibility. Is there a good way to avoid this situation? There are no compiler warnings. Is there a way to make xcode prevent this? I cannot see very many situations where you would set a property to the value of its underlying instance variable (maybe to trigger a KVO binding?), but I don't see myself doing that in majority of cases. I understand the above code is synthetic and should be done with @synthesize, but I am just using it as a simplified example to illustrate my point.

• Ruby on Rails - Calendar Display

  - by user335725

  We want to create a calendar view in a room scheduling application. The outcome we want is to have hours open (variable depending on day) across the top of the grid and the names of the rooms down the left side of the grid. The body would be populated with bookings for that day. The visual we're seeking is similar to the "Weekly Builder" plugin for Rails (http://dmix.ca/2009/06/weeklybuilder-a-weekly-calendar-plugin-for-rails/). We've tried using CSS to create variably-sized images, but this isn't working out. Are there any plugins available or other ways anyone can think of to accomplish this kind of visual? Thanks

• [java] Threading socket handler for two sided communication in tcp port

  - by raven

  I want to make a chat which will be programed in java. one computer will host the server and the other one will initiate the socket [tcp port]. now from what I read there should be a loop that will constantly read the socket which means it will make the code stuck. I have a button that is 'actionperformed' on mouse release, I want to know if it will work along with the loops that constantly reads the socket so that it will also send the infromation I wrote. If I must thread it, I want to know if the run() method must be void because if I thread it it will mean creating a new class, and the whole GUI is one big class which includes a text area, and it's private. also how can I extract the information from the socket directly to the text area? lets say the textarea variable is called "chatOutput". thx :)
