  • PHP Value Object auto create

    - by JonoB
    Assume that I have a class value object defined in php, where each variable in the class is defined. Something like: class UserVO { public $id; public $name; } I now have a function in another class, which is expecting an array ($data). function save_user($data) { //run code to save the user } How do I tell php that the $data parameter should be typed as a UserVO? I could then have code completion to do something like: $something = $data->id; //typed as UserVO.id $else = $data->name; //typed as UserVO.name I'm guessing something like the following, but this obviously doesnt work $my_var = $data as new userVO();

  • Displaying Fields (and/instead of Properties) in a PropertyGrid

    - by Jenk
    I'd like to use a PropertyGrid to manipulate the data on some objects, however these objects don't have properties, they have fields. Thus a property grid doesn't display them (high five MS!) Before anyone posts "just use properties": I can't at the moment.. these objects are DTOs and are used to send data to a VB6 Interop dll, thus all the parameters for the method calls are "ref" parameters (high five MS!), and C# won't compile if you use a property instead of a field or variable (high five MS!). No, I am not going to create local variables for every property on any given object. There many, many fields, and many, many test cases that would need updating, as well as the production code it self, and this post/question may be the path of least resistance. :)

  • CakePHP: Ajax view problem (nothing in the view showing)

    - by Adim
    I created a function in my controller called addToPlaylist($songName). I wanted to add these song names to an array and then a session variable using an Ajax call. The first time i did this i got an error saying i do not have a template file to display in the chosen div ("add_to_playlist.ctp was missing"). I created this file and everything seemed to be working correctly. Basically I went to bed woke up and it is broken (it is possible I changed something before I went to bed). The problem now is that it does not show anything when i click the ajax link. when i click on the ajax link it seems to call the function but nothing displays in the view (except debug info) even when i delete the view (add_to_playlist.ctp) i get no errors, I just see debug info now.

  • Background Image displaying in Design view but not in browser? (Visual Studio 2008)

    - by Tom Hutchinson
    I'm new to CSS and this issue in Visual Studio is driving me mad! I have a background image defined within a simple style sheet... body { background-image: url(Images\Greenhouse.jpg); background-position: center; } My style sheet is referenced within the HTML code... <head runat="server"> <title></title> <link rel="Stylesheet" type="text/css" href="Stylesheet.css"/> </head> The background image shows in design view but in the browser, nothing! I've tried changing position etc and refreshed the browser, cleared the cache etc. This happens with all my images. Images are within the project folder (\Images) and added to the solution explorer in VS. Tried "", changing image file names etc, nothing is working!

  • SELECT with a Replace()

    - by andyjohnson
    I have a table of names and addresses, which includes a postcode column. I want to strip the spaces from the postcodes and select any that match a particular pattern. I'm trying this (simplified a bit) in T-SQL on SQL Server 2005: SELECT Replace(Postcode, ' ', '') AS P FROM Contacts WHERE P LIKE 'NW101%' But I get the following error; Msg 207, Level 16, State 1, Line 3 Invalid column name 'P'. If I remove the WHERE clause I get a list of postcodes without spaces, which is what I want to search. How should I approach this? What am I doing wrong?

  • Where's the font setting for folders in the Package Explorer?

    - by Carl Smotricz
    I'm talking about Eclipse (3.5 = Galileo), running under Kubuntu 9.10 and I have the Subversive plugin. I've been moved from Gnome-Ubuntu to Kubuntu, and one side effect was that some fonts are now just too tiny to read. File names in the explorer have a decent size, but folders are shown in a too-small font, and after having adjusted all the fonts in General|Appearance|Colors and Fonts the folders are unchanged. Maybe I'm just blind. I'd appreciate it if someone could point me to where I can adjust the font for folders in the Package Explorer

  • Managing StringBuilder Resources in C#

    - by Jim Fell
    Hello. My C# (.NET 2.0) application has a StringBuilder variable with a capacity of 2.5MB. Obviously, I do not want to copy such a large buffer to a larger buffer space every time it fills. By that point, there is so much data in the buffer anyways, removing the older data is a viable option. Can anyone see any obvious problems with how I'm doing this (i.e. am I introducing more performance problems than I'm solving), or does it look okay? tText_c = new StringBuilder(2500000, 2500000); private void AppendToText(string text) { if (tText_c.Length * 100 / tText_c.Capacity > 95) { tText_c.Remove(0, tText_c.Length / 2); } tText_c.Append(text); } Thanks.

  • How can a running application in Linux/*nix determine its own absolute path?

    - by Dave Wade-Stein
    Suppose you run the application 'app' by typing 'app', rather than its absolute path. Due to your $PATH variable, what actually runs is /foo/bar/app. From inside app I'd like to determine /foo/bar/app. argv[0] is just 'app', so that doesn't help. I know in Linux I can get do pid = getpid(); and then look at the /proc/pid/exe softlink, but that doesn't work on other *nix. Is there a more portable way to determine the dir in which the app lives?

  • Stop Rails from unloading a module in development mode

    - by Gareth
    I have a module in my Rails app that lives in /lib module MyModule mattr_accessor :the_variable class << self def setup yield this end end end From my environments/#{RAILS_ENV}.rb file I can then set an environment-specific value for the_variable: MyModule.setup do |my_module_config| my_module_config.the_variable = 42 end This is lovely, and it seems to work (almost) fine. The problem is that in development mode, Rails via ActiveSupport::Dependencies unloads a load of modules, and reloads them in time for the new request. This is usually a great behaviour because it means you don't need to restart your localhost server when you make a code change. However, this also clears out my initialised the_variable variable, and when the next request comes in the initialiser (obviously) isn't run again. The net effect is that subsequent requests end up having MyModule.the_variable set to nil rather than the 42 that I'm looking for. I'm trying to work out how to stop Rails unloading my module at the end of the request, or alternatively find another way to cleanly provide environment specific configuration for my modules. Any ideas? :-/

  • How do I dynamically update an instance array to hold a list of dynamic methods on instantiation?

    - by Will
    I am trying to dynamically define methods based on xml mappings. This works really well. However I want to create an instance variable that is a array of the dynamically defined methods. My code looks something like this def xml_attr_reader(*args) xml_list = "" args.each do |arg| string_val = "def #{arg}; " + " xml_mapping.#{arg}; " + "end; " self.class_eval string_val xml_hash = xml_list + "'#{arg}'," end self.class_eval "@xml_attributes = [] if @xml_attributes.nil?;" + "@xml_attributes = @xml_attributes + [#{xml_list}];" + "puts 'xml_attrs = ' + @xml_attributes.to_s;" + "def xml_attributes;" + " puts 'xml_attrs = ' + @xml_attributes.to_s;" + " @xml_attributes;" + "end" end So everything works except when I call xml_attributes on an instance it return null (and prints out 'xml_attrs = '). While the puts before the definition actually prints out the correct array. (when I instantiate the instance)

  • Using a Function returning apointer as LValue

    - by Amrish
    Why cant I used a function returning a pointer as a lvalue? For example this one works int* function() { int* x; return x; } int main() { int* x = function(); x = new int(9); } but not this int* function() { int* x; return x; } int main() { int* x; function() = x; } While I can use a pointer variable as a lvalue, why can't I use a function returning a pointer as a lvalue? Also, when the function returns a refernce, instead of a pointer, then it becomes a valid lvalue.

  • C# - Getting record from a row using DataRow

    - by pinkcupcake
    I'm trying to get record of a row using DataRow. Here's what I've done so far: uID = int.Parse(Request.QueryString["id"]); PhotoDataSetTableAdapters.MembersTableAdapter mem = new PhotoDataSetTableAdapters.MembersTableAdapter(); PhotoDataSet.MembersDataTable memTable = mem.GetMemberByID(uID); DataRow[] dr = memTable.Select("userID = uID"); string uName = dr["username"].ToString(); Then I got the error: Cannot implicitly convert type 'string' to 'int' The error points to "username". I don't know what's wrong because I'm just trying to assign a string variable to a string value. Anyone figures out the reason of the error? Please help and thanks.

  • Double indirection and structures passed into a function

    - by ZPS
    I am curious why this code works: typedef struct test_struct { int id; } test_struct; void test_func(test_struct ** my_struct) { test_struct my_test_struct; my_test_struct.id=267; *my_struct = &my_test_struct; } int main () { test_struct * main_struct; test_func(&main_struct); printf("%d\n",main_struct->id); } This works, but pointing to the memory address of a functions local variable is a big no-no, right? But if i used a structure pointer and malloc, that would be the correct way, right? void test_func(test_struct ** my_struct) { test_struct *my_test_struct; my_test_struct = malloc(sizeof(test_struct)); my_test_struct->id=267; *my_struct = my_test_struct; } int main () { test_struct * main_struct; test_func(&main_struct); printf("%d\n",main_struct->id); }

  • iPhone UITableViewCell: repositioning the textLabel

    - by user359784
    Hello, I am new to iPhone development and I am currently working on a simple RSS reader app. The problem I am having is that I need to reposition the textLabel inside the UITableViewCells. I have tried setFrame or setCenter but it doesn't do anything. Does anyone know what I need to do inside the tableView:cellForRowAtIndexPath: method to reposition the textLabel at the top of the cell (x = 0, y = 0)? Thank you PS: The UITableViewCell is referenced by a variable called cell. I have tried [cell setFrame:CGRectMake(0, 0, 320, 20)] with no success.

  • Hibernate pluralization

    - by matiasf
    I have A MySQL database currently in production use for a CakePHP application A Java SE application accessing the same database via Hibernate, currently in development. I'm using the Netbeans "automigrate" feature to create the POJO classes and XML files (do I really need the XML files when using annotations?). As the schema is quite complex creating the tables manually is way too much work. Cake expects all DB tables to be pluralized (the Address class is automagically mapped to the addresses table). When running the Netbeans automigration it then does pluralization on the already pluralized table names (I'm getting Addresses.java and setAddresseses() methods). I know I'm asking for trouble running two very different data layers against the same database, but I'd like to know if it's possible to have Netbeans generating the POJO classes in singular form or if there is another (better) way to manage this.

  • Generalised XML Serialization

    - by Tom W
    I apologise for asking a question that's probably been asked hundreds of times before, but I don't seem to be able to find an answer in the archives; probably because my question is too basic. I know that XML Serialization by default only touches public members and properties. Properties very often mask a private variable; particularly if they're readonly. Serializing these is fine; the value that the instance exposes to the world is what goes into the XML. But if Deserialization of the same data can't put the value back where it belongs, what's the point of doing it? Is there something I'm missing about how XML Serialization is normally used for classes with masking properties? Surely it can't be that the only answer is explicitly implementing Read/WriteXML - because that's more effort than it's worth!

  • Screen recorder for tracking back your steps while debugging?

    - by hstoerr
    I am wondering whether there is a screen recorder that is usable for checking what exactly you did a couple of minutes ago while debugging, or just checking what value for a variable was displayed the last time you hit that breakpoint etc. (Of course this latter question would be something terrific for an IDE to implement, but I've never seen something like that so far. :-) For this you would need a screen recorder that could record all day and preferably automatically delete the recording the recording that is, say, older than an hour. Probably the recording format should be something that is good for screen recording instead of natural scenes. Do you know a screen recorder like that or at least one that comes close?

  • Flash AS3: automate property assignment to new instance from arguments in constructor

    - by matt lohkamp
    I like finding out about tricky new ways to do things. Let's say you've got a class with a property that gets set to the value of an argument in the constructor, like so: package{ public class SomeClass{ private var someProperty:*; public function SomeClass(_someProperty:*):void{ someProperty = _someProperty; } } } That's not exactly a hassle. But imagine you've got... I don't know, five properties. Ten properties, maybe. Rather then writing out each individual assignment, line by line, isn't there a way to loop through the constructor's arguments and set the value of each corresponding property on the new instance accordingly? I don't think that the ...rest or arguments objects will work, since they only keep an enumerated list of the arguments, not the argument names - I'm thinking something like this would be better: for(var propertyName:String in argsAsAssocArray){this[propertyName] = argsAsAssocArray[propertyName];} ... does something like this exist?

  • JavaScript, transform object into array

    - by Šime Vidas
    I've got an object: var obj = { "Mike": 24, "Peter": 23, "Simon": 33, "Tom": 12, "Frank": 31 }; I want to create an array that holds the values of the object. The keys (key names) can be disregarded: [24, 23, 33, 12, 31] The order of the values is NOT important! One solution (obviously) would be do have a function that takes the values and puts them into an array: var arr = valuesToArray(obj); I will accept such a function as the answer. However, I would be more pleased if there would be an API function (ECMAScript, jQuery, browser-specific, ...) that could do this. Is there such a thing?

  • How to localize static content in database with Django

    - by man with python
    My app has tables for languages and countries (actually django-countries at the moment, but open for suggestions). The tables are populated when I initialize the database and remain static after that. What would be the ideal localization mechanism for the contents of these tables, so that I can show the country and language names to users in their chosen site language? I'm aware of projects like django-multilingual and transdb, but IMO they are more suitable for dynamic content, i.e. stuff that's supposed to be modified. Please englighten me!

  • basic json > struct question

    - by danwoods
    I'm working with twitter's api, trying to get the json data from http://search.twitter.com/trends/current.json which looks like: {"as_of":1268069036,"trends":{"2010-03-08 17:23:56":[{"name":"Happy Women's Day","query":"\"Happy Women's Day\" OR \"Women's Day\""},{"name":"#MusicMonday","query":"#MusicMonday"},{"name":"#MM","query":"#MM"},{"name":"Oscars","query":"Oscars OR #oscars"},{"name":"#nooffense","query":"#nooffense"},{"name":"Hurt Locker","query":"\"Hurt Locker\""},{"name":"Justin Bieber","query":"\"Justin Bieber\""},{"name":"Cmon","query":"Cmon"},{"name":"My World 2","query":"\"My World 2\""},{"name":"Sandra Bullock","query":"\"Sandra Bullock\""}]}} My structs look like: type trend struct { name string query string } type trends struct { id string arr_of_trends []trend } type Trending struct { as_of string trends_obj trends } and then I parse the JSON into a variable of type Trending. I'm very new to JSON so my main concern is making sure I've have the data structure correctly setup to hold the returned json data. I'm writing this in 'Go' for a project for school. (This is not part of a particular assignment, just something I'm demo-ing for a presentation on the language)

  • How to limit the number of connections to a SQL Server server from my tomcat deployed java applicati

    - by CJ
    I have an application that is deployed on tomcat on server A and sends queries to a huge variety of SQL Server databases on an server B. I am concerned that my application could overload this SQL Server database server and would like some way to preventing it making requests to connect to any database on that server if some arbitrary number of connections were already in existence and unclosed. I am looking at using connection pooling but am under the impression that this will only pool connections to a specific database on the SQL Server server, I want to control the total of these combined connections that will occur to many different databases (incidentally I can only find out the names of individual db's dynamically as they change day to day). Will connection pooling take care of this for me, are am I looking at this from the wrong perspective? I have no access to the configuration of the SQL Server server. Links to tutorials or working examples of your suggested solution are most welcome!

  • How to iterate over every property of an object in javascript?

    - by OverloadUT
    Is there a way to iterate over every property of an object using the Prototype JavaScript framework? Here's the situation: I am getting an AJAX response in JSON that looks something like this: {foo: 1, bar: 2, barobj: {75: true, 76: false, 85: true}} If I evaluate that json response in to a variable response, I want to be able to iterate over each property in the response.barobj object to see which indexes are true and which are false. Prototype has both Object.keys() and Object.values() but oddly seems to not have a simple Object.each() function! I could take the results of Object.keys() and Object.values() and cross-reference the other as I iterate through one, but that is such a hack that I am sure there is a proper way to do it!
