  • Changing the way widgets are rendered/displayed in a form on the template

    - by user334017
    I have a form with a few other embedded forms and some various widgets. The widgets are all saved in an array $form['elements'] and for some of them, I want to display labels and things, but for others I only want to display the basic rendering. foreach($form['elements'] as $elem) echo $elem->render(); this displays everything about the widget. The way it is right now, I couldn't for example call $elem['..'] because the different subforms appear in a random order and have different variable names. I assume I could still put some checks in the template, but it seems easier to fix this in the widget class, like override one of the render functions or something. How would I go about doing this or do you have any links that could help me understand how do do this? on a side note, one of my widgets is the sfWidgetFormChoice and I have no clue where it actually renders or how renderer_classes work

  • Initializing a array after declaration

    - by robUK
    Hello, gcc 4.4.3 c89 I have the following code as a sample of what I am trying to do. I don't know the actual size of the array, until I enter the function. However, I don't think I can set the array size after I have declared it. I need it global as some other functions will need to access the device names. Many thanks for any suggestions, /* global */ char *devices_names[]; void fill_devices(size_t num_devices) { devices_names[num_devices]; /* start filling */ }

    - by sajjadlove
    Hi All I'm very confused about this issue and can't to underestand it.In the Enumerable Documentation, I readed this: that implement System.Collections.Generic.IEnumerable and some methods like Select() return IEnumerable that we can use from other methods like Where() after using that.for example: names.Select(name => name).Where(name => name.Length > 3 ); but Enumerable doesn't inherits from IEnumerable and IEnumerable doesn't contain Select(),Where() and etc too... have i wrong ? or exists any reason for this?

  • Dynamically changing databases in SQL Server 2000

    - by spuppett
    At work we have a number of databases that we need to do the same operations on. I would like to write 1 SP that would loop over operations and set the database at the beginning of the loop (example to follow). I've tried sp_executesql('USE ' + @db_id) but that only sets the DB for the scope of that stored procedure. I don't really want to loop with hard coded database names because we need to do similar things in many different places and it's tough to remember where things need to change if we add another DB. Any thoughts Example: DECLARE zdb_loop CURSOR FAST_FORWARD FOR SELECT distinct db_id from DBS order by db_id OPEN zdb_loop FETCH NEXT FROM zdb_loop INTO @db_id WHILE @@FETCH_STATUS = 0 BEGIN USE @db_id --Do stuff against 3 or 4 different DBs FETCH NEXT FROM zdb_loop INTO @db_id END CLOSE zdb_loop DEALLOCATE zdb_loop

  • rails eval code

    - by xpepermint
    Hey. I have to do a coll inside my model like this: import = Import.find(id) status = User.find(import.user_id).{XXX}.import(import.file.path) Notice a {XXX} which should be replaced by a dinamic variable of a submodel. Model User has_many groups, clients and products. In translation this would be status = User.find(import.user_id).groups.import(import.file.path) status = User.find(import.user_id).clients.import(import.file.path) status = User.find(import.user_id).products.import(import.file.path) I was thinking of import = Import.find(id) status = eval("User.find(#{import.user_id}).#{import.model}").import(import.file.path) but this gives me an error 'TypeError: can't convert nil into String'. Please tell me how would you fix that. Thx!

  • sql count function

    - by suryll
    Hi I have three tables and I want to know how much jobs with the wage of 1000 an employee has had The first SQL query gives me the names of all the employees that has recieved 1000 for a job SELECT distinct first_name FROM employee, job, link WHERE job.wage = 1000 AND job.job_id = link.job_id and employee.employee_id = link.employee_id; The second SQL query gives me the total number for all employees of how much jobs they have made for 1000 SELECT count(wage) FROM employee, job, link WHERE job.wage = 1000 AND job.job_id = link.job_id and employee.employee_id = link.employee_id; I was wondering if there was a way of joining both queries and also making the second for each specific employee???

  • What is the best instance type to use for hosting a website on ec2?

    - by Josh
    Amazon offers two instance types on EC2: 1) On-Demand and 2) Reserved. After reading the docs on these, I don't really understand the difference from an end-user perspective. More specifically, I'd like to know the answer to this question: is one or the other better for web applications? Based on their names and descriptions, it seems as though on-demand instances may get wiped away from the server altogether if they're not in use which means that they need to be restarted when a request finally does come in. That seems like a pretty bad thing for a website. Am I just misinterpreting the docs? Thanks!

  • Keeping Score in XNA Game

    - by Seven
    Hi. I'm following an XNA tutorial and have the following code for collision detecting (detecting when a bullet collides with a target). Basically I'm looking to increment a score variable to display the score to the screen without re-writing the whole program. No matter where I place it in this method it seems to start incrementing from the number of targets, not from zero. Is there something simple I'm missing here? Any help would be greatly appreciated. Thanks. private CollisionType CheckCollision(BoundingSphere sphere) { if (completeCityBox.Contains(sphere) != ContainmentType.Contains) return CollisionType.Boundary; for (int i = 0; i < targetList.Count; i++) { if (targetList[i].Contains(sphere) != ContainmentType.Disjoint) { targetList.RemoveAt(i); i--; AddTargets(); return CollisionType.Target; } } return CollisionType.None; }

  • nested list comprehension using intermediate result

    - by KentH
    I am trying to grok the output of a function which doesn't have the courtesy of setting a result code. I can tell it failed by the "error:" string which is mixed into the stderr stream, often in the middle of a different conversion status message. I have the following list comprehension which works, but scans for the "error:" string twice. Since it is only rescanning the actual error lines, it works fine, but it annoys me I can't figure out how to use a single scan. Here's the working code: errors = [e[e.find('error:'):] for e in err.splitlines() if 'error:' in e] The obvious (and wrong) way to simplify is to save the "find" result errors = [e[i:] for i in e.find('error:') if i != -1 for e in err.splitlines()] However, I get "UnboundLocalError: local variable 'e' referenced before assignment". Blindly reversing the 'for's in the comprehension also fails. How is this done? THanks. Kent

  • Java Package, Project , NoSuchMethod error

    - by hamam
    I have 2 projects linked and these 2 projects each have a package under them. XProject - XPackage - XClass - X1Method(); X2Method(); YProject - YPackage - YClass - Y1Method(); I'm trying to call X1 and X2 methods from Y1 Method. I can call X1 Method but when I call X2 method I get a runtime error (java.lang.NoSuchMethodError:) All methods are public and there is nothing wrong with method names. It is just nonsense to have one of them working while other is giving runtime errors. Any help would be appreciated. Thanks.

  • Find record whose field 'name' not contained within any other record

    - by charlie
    I have a model Foo with a String bar and a String name. Some records' bar contain the name of other records in them. This is intentional. I want to find the "root Foo" records - that is, the ones where their name do not appear in the bar records of any other Foo records. Example: Foo id: 1 name: 'foo1' bar: 'something something' id: 2 name: 'foo2' bar: 'foo1 something' id: 3 name: 'foo3' bar: 'foo1, foo4' My method root_foos would return foo2 and foo3 since their names do not appear in any bar string. edit: I don't want to use a relation or foreign key here - just this method.

  • Explicit constructor still has default values even though a default constructor is not invoked.

    - by Phoenix
    According to my understanding a default constructor initializes the state of the object to default values, so if i provide an explicit no-arg public constructor like this then how are the values of d and e still getting initialized to zero because in this case the default constructor is not invoked. public class B extends A{ private int d; private int e; public B() { System.out.println(d); System.out.println(e); } } EDIT:: The only thing default constructor does is call to super() then how come if i have a explicitly mentioned a constructor here and A has a protected variable say c which is initialized to 17 in its constructor. Should I not be explicitly calling super() to be able to see that change since I'm using my own constructor ? Why is B still getting the value of 17 through inheritance ?

  • Wordpress Custom Type permalink containing Taxonomy slug

    - by treznik
    I'm trying to create a permalink pattern for a Custom Type, that includes one of its taxonomies. The taxonomy name is known from the start (so I'm not trying to add or mix all of its taxonomies, just a specific one), but the value will by dynamic, of course. Normally, the Custom Type permalink is built using the rewrite arg with the slug param, but I don't see how I could add a dynamic variable in there. http://codex.wordpress.org/Function_Reference/register_post_type I'm guessing a custom solution is required, but I'm not sure what the best unintrusive approach would be. Is there a known practice for this or has anyone built something similar recently? I'm using WP 3.2.1 btw.

  • jquery Troubles with binding to an element by id

    - by Alonzo
    Hi What im trying to do is that when the esc key is pressed on the text input field (id = txtSearch), some code will run. this is my code: $(document).ready(function() { $('#txtSearch').bind('keyup', function(e) { var characterCode; // literal character code will be stored in this variable if (e && e.which) { //if which property of event object is supported (NN4) e = e; characterCode = e.which; } else { characterCode = e.keyCode; } if (characterCode == 27) //if esc key { //do stuff } }); } It doesnt work for me. however, if i would change that line: $('#txtSearch').bind('keyup', function(e) { with: $(document).bind('keyup', function(e) { everything works. but i dont want to bind the keyup with esc to the whole document... any suggestions on how i can bind the the keyup only with the specific text search element? (or its containing div or something) Thanks!

  • Syntax problem when checking for a file

    - by Luke
    This piece of code has previously worked but I have C&P it to a new place and for some reason, it now won't work! <? $user_image = '/images/users/' . $_SESSION['id'] . 'a.jpg'; if (file_exists(realpath(dirname(__FILE__) . $user_image))) { echo '<img src="'.$user_image.'" alt="" />'; } else { echo '<img src="/images/users/small.jpg" alt="" />'; } ?> As you can see, I am checking for a file, if exists, showing it, if not, showing a placeholder. The $_SESSION['id'] variable does exist and is being used elsewhere within the script. Any ideas what the problem is? Thanks

  • C++ Static Array Initialization - Memory Issue

    - by donalmg
    Hi, I have a header file which contains a member variable declaration of a static char array: class ABC { public: static char newArray[4]; // other variables / functions private: void setArray(int i, char * ptr); } In the CPP file, I have the array initialized to NULL: char ABC::newArray[4] = {0}; In the ABC constructor, I need to overwrite this value with a value constructed at runtime, such as the encoding of an integer: ABC::ABC() { int i; //some int value defined at runtime memset(newArray, 0, 4); // not sure if this is necessary setArray(i,newArray); } ... void setArray(int i, char * value) { // encoding i to set value[0] ... value [3] } When I return from this function, and print the modified newArray value, it prints out many more characters than the 4 specified in the array declaration. Any ideas why this is the case. I just want to set the char array to 4 characters and nothing further. Thanks...

  • Jquery mobile function calls before Ajax Request end

    - by rpmlins
    Here is my problem. When My Home page shows, I call the LoadUser functions, which on success, sets the globalUser variable with the returned json, and after it loads I call the alert function but it says globalUser is undefined. I have tried many other work arounds, but I always get the undefined mesage. If I call the alert(globalUser); on the success function, it works as expected alerting the object. $('#Home').live('pageshow', function(event) { $.when(LoadUser()).done(function(a1) { alert(globalUser); }); }); function LoadUser() { $.ajax({ // connects with the web service and validate de user input url: "http://localhost:51396/Icademy.asmx/GetUser", contentType: "application/json; charset=utf-8", data: { "userName": "'rodrigo'" }, dataType: "jsonp", success: function(json) { globalUser = JSON.parse(json.d); return globalUser; }, error: function(ret) { alert("Um erro ocorreu, tente novamente mais tarde."); } }); }

  • [PHP] Variables loaded from a separate script are not defined within functions

    - by Goro
    Hello, I use settings.php to store general settings for my application. When I load this settings file, I can use the variables defined in settings.php in the script itself, but not within any functions I define in it. For example, in my class definition, myclass.php: <?php $preIP = dirname(__FILE__); require_once( "preIP/settings.php" ); class MyClass { ... public function foo() { echo $variable_from_settings; } } The code in the function foo() will not work (the variable will not be defined). The settings.php file looks like this: $variable_from_settings = "bar"; Thanks,

  • Ignore document style rules in one element.

    - by panzi
    I write a greasemonkey script that adds sticky notes to websites. Because there sometimes are pretty strange style rules used in some websites the sticky notes sometimes turn up messed up (or at least not looking like I want them to look). Is there a way to say "under this element do not apply any generic stylerules"? So that rules associated with tag names are not applied, but rules associated with certain classes and ids still are. Or does anyone have a better idea on how to ensure that only my styles are applied to the sticky notes?

  • is it possible to create a multi-project template that references n number of existing projects and

    - by jcollum
    The situation: I need to create about 40+ solutions that all reference 3 projects and have one project that is unique to each one. I'd like to create a multi-project template that does this, but from what I've read it looks like it's very difficult or impossible (related SO question, but doesn't answer). I want my solution to look like this (names changed of course): These three are used by all solutions created under this "family": MyCompany.Extensions MyCompany.MyProject.Tests.Shared MyCompany.MyProject.Scripts This one is the one that makes the solution unique, 123, 124, 125 etc: MyCompany.MyProject.Tests.Unit123 Is it possible to set up a multi-project template that will generate this structure?
