How do I save a macro consisting of multiple search and replace into my .vimrc

- by Doppelganger

I have a macro that I use to replace special characters for its html entities. I would like to save it in my .vimrc. According to this, I should use let @r=' *macro_text_goes_here* '. The problem is that my macro is a series of search and replace, something like this: :%s:á:\á:Ige :%s:é:\é:Ige :%s:í:\í:Ige So, I've tried with ^V-enter, <enter>, <CR> using real line breaks, but it never works. On the other side, if I put the text on a register and then run the macro, it works as expected.

php regular expression help finding multiple filenames only not full URL

- by jason

I am trying to fix a regular expression i have been using in php it finds all find filenames within a sentence / paragraph. The file names always look like this: /this-a-valid-page.php From help i have received on SOF my old pattern was modified to this which avoids full urls which is the issue i was having, but this pattern only finds one occurance at the begging of a string, nothing inside the string. /^\/(.*?).php/ I have a live example here: http://vzio.com/upload/reg_pattern.php

Download multiple files from an array C#

Hi everyone, I have an array of file names which I want to download. The array is currently contained in a string[] and it is working inside of a BackgroundWorker. What I want to do is use that array to download files and output the result into a progress bar which will tell me how long I have left for completion. Is there a way I can do this. Thanks.

T4MVC calling controller methods multiple times?

- by Maslow

I suspected there was some hidden magic somewhere that stopped what looks like actual method calls all over the place in T4MVC. Then I had a view fail to compile, and the stackTrace went into my actual method, not the generated code in T4MVC. <%=Ajax.ActionLink("Apply", "Apply", new RouteValueDictionary() { { "shortName", item.Shortname } }, new AjaxOptions() { UpdateTargetId = "masterstatus" })%> <%=Html.ActionLink("Apply",MVC.Alliance.Apply(item.Shortname),new AjaxOptions() { UpdateTargetId = "masterstatus" }) %> The second method threw an exception on compile because the method Apply in my controller has an [Authorize] attribute so that if someone that isn't logged on clicks this, they get redirected to login, then right back to this page. There they can click on apply again, this time being logged in. And yes I realize one is Ajax.ActionLink while the other is Html.ActionLink I did try them both with the T4MVC version. Is this a fluke or is it actually calling into the real methods and running my database calling code just to generate the views?

jQuery inconsistent .remove by class on element with multiple classes

- by pedalpete

I've got a page where messages and associated elements (responses, forwards, etc) all share a class based on the database id of the parent. For example this is a message this is another message this is a comment this is another comment tim posted a new message sara forwarded a message to john at times I need to remove all elements with the same id, so I originally had jQuery('div#'+id).remove(); but that would sometimes not remove all the ids because ids are supposed to be unique. So I added the id as a class. now I use jQuery('div.'+id).remove(); but this seems to be about 80% effective, and sometimes the divs aren't being removed. I'm not sure if the issue is because the div has more than one class, but I need the classes because that is how I refer to the elements when somebody clicks. For instance, jQuery('div.message').click(function(){ get the id, send it to the server and get the message }); is there something wrong I'm doing here? or is there a better way to do this?

Dropdown dependent values to be fetch from multiple models using ajax in Yii

- by newuser

I searched all the documentation over Yii but not got the answer of it.So I came here finally. I have the following schema Table Schools +------------------+--------------+------+-----+---------------------+----------------+ | Field | Type | Null | Key | Default | Extra | +------------------+--------------+------+-----+---------------------+----------------+ | id | int(10) | NO | PRI | NULL | auto_increment | | school_name | varchar(100) | NO | | | | +------------------+--------------+------+-----+---------------------+----------------+ Table Students +------------------+--------------+------+-----+---------------------+----------------+ | Field | Type | Null | Key | Default | Extra | +------------------+--------------+------+-----+---------------------+----------------+ | id | int(10) | NO | PRI | NULL | auto_increment | | school_id | int(10) | NO | FK | | | | student_name | varchar(100) | NO | | | | | roll_no | varchar(80) | NO | | | | | class | varchar(20) | NO | | | | | | subjects | varchar(100) | NO | | | | +------------------+--------------+------+-----+---------------------+----------------+ I have made models and CRUD for the both models.In models my relation is like this In Students.php the relation is like public function relations() { // NOTE: you may need to adjust the relation name and the related // class name for the relations automatically generated below. return array( 'School' => array(self::BELONGS_TO,'Schools','school_id'), ); } In Schools.php the relation is like public function relations() { // NOTE: you may need to adjust the relation name and the related // class name for the relations automatically generated below. return array( 'student' => array(self::HAS_MANY, 'Students', 'school_id'), ); } Now I made the two models rendered in a single page so that I can enter all the respective fields in a single form. In the _form.php file of Students I have made some change in student_name like this <div class="row"> <?php echo $form->labelEx($model,'student_name'); ?> <?php echo $form->dropdownList($model,'student_name', CHtml::listData(Students::model()->findAll(), 'id', 'student_name'), array('empty'=>array('Select'=>'--Select One---'))); ?> <?php echo $form->error($model,'student_name'); ?> Now for this piece of code I got all the student name from the Student model. So my problem is when I am getting the student name from the dropdown list and going to select a student it will also fetch all the respective values of the student to be rendered in the _form.php without click on save button.So that user don't have to put it again manually. I think ajax and json encode will work here but don't know how to make them work here. [Update] Here is StudentsController code public function actionDisCoor() { $model = School::model()->findByPk($_POST['Students']['student_id']); $data=CHtml::listData($data,'id','name'); foreach($data as $value=>$name) { echo CHtml::tag('option',array('value'=>$value),CHtml::encode($name),true); } } Here is _form.php code for Students <div class="row"> <?php echo $form->labelEx($model,'student_name'); ?> <?php $List = CHtml::listData(Students::model()->findAll(), 'id', 'student_name'); ?> <?php echo $form->dropdownList($model,'student_name',$List, array('onChange'=>CHtml::ajax(array( 'url' => CController::createUrl('DisCoor'), 'type' => 'POST', 'update'=>'#school_id', )),'style'=>'width:180px;' ) )?> <?php echo $form->error($model,'student_name'); ?> </div> After all that when I saw in firebug I got the error.Here is the screen shot

Should I include user_id in multiple tables?

- by Drarok

I'm at the planning stages of a multi-user application where each user will only have access their own data. There'll be a few tables that relate to each other, so I could use JOINs to ensure they're accessing only their data, but should I include user_id in each table? Would this be faster? It would certainly make some of the queries easier in the long run. Thanks!

belongs_to with multiple models

- by julie p

Hi there! I am a Rails noob and have a question. I have a feed aggregator that is organized by this general concept: Feed Category (books, electronics, etc) Feed Site Section (home page, books page, etc) Feed (the feed itself) Feed Entry So: class Category < ActiveRecord::Base has_many :feeds has_many :feed_entries, :through => :feeds, :limit => 5 validates_presence_of :name attr_accessible :name, :id end class Section < ActiveRecord::Base has_many :feeds has_many :feed_entries, :through => :feeds, :limit => 5 attr_accessible :name, :id end class Feed < ActiveRecord::Base belongs_to :categories belongs_to :sections has_many :feed_entries validates_presence_of :name, :feed_url attr_accessible :name, :feed_url, :category_id, :section_id end class FeedEntry < ActiveRecord::Base belongs_to :feed belongs_to :category belongs_to :section validates_presence_of :title, :url end Make sense? Now, in my index page, I want to basically say... If you are in the Category Books, on the Home Page Section, give me the feed entries grouped by Feed... In my controller: def index @section = Section.find_by_name("Home Page") @books = Category.find_by_name("Books") end In my view: <%= render :partial => 'feed_list', :locals => {:feed_group => @books.feeds} -%> This partial will spit out the markup for each feed entry in the @books collection of Feeds. Now what I need to do is somehow combine the @books with the @section... I tried this: <%= render :partial => 'feed_list', :locals => {:feed_group => @books.feeds(:section_id => @section.id)} -%> But it isn't limiting by the section ID. I've confirmed the section ID by using the same code in the console... Make sense? Any advice? Thanks!

How to repeat a particular execution multiple times

Equality Comparison with Multiple Instances/IEqualityComparer problems in LINQ

- by Stacey

This is similar to my last question; but from a different angle. http://stackoverflow.com/questions/2792393/see-if-item-exists-once-in-enumerable-linq Given the following set of items, and lists containing them... Item 1 Item 2 Item 3 Item 4 Item 5 class Item { string Name { get; set; } } List<Item> available = new List<Item>() { Item 1 Item 1 Item 2 Item 3 Item 5 } List<Item> selected = new List<Item>() { Item 1 Item 2 Item 3 } I need to make a third List that has everything from "available", except what is in "selected". However 'Item 1' is in 'available' twice, but only in 'selected' once. Since they are instances of the same item, I am having trouble figuring out the appropriate logic to accomodate this. The final array should look like... List<Item> selectable = new List<Item>() { Item 1 Item5 }

how to read an address in multiple formats like google maps

notice that on google maps you can input the address any way you like. as long as it is a valid address...google maps will read it. In some ruby book I had seen code snippet for something like this, but with phone numbers. Any ideas how this could be done for addresses? in language of your choice. EDIT: i dont care about a "valid" address. I just want to parse an address. so that 123 fake street, WA, 34223 would be an address and so will 123 fake street WA 34223

How to implement code for multiple buttons using c++ in Silverlight for Windows Embedded

- by Abhi

Dear all I have referred the following link: Silverlight for Windows Embedded By referring this link i created a demo application which consist of two buttons created using Microsoft expression blend 2 tools. And then written a code referring the above site. Now my button names are "Browser Button" and "Media Button". On click of any one of the button i should able to launch the respective application. I was able to do for "Browser Button" but not for "Media Button" and if i do for "Media Button" then i am not able to do for "Browser Button".. I mean to say that how should i create event handler for both the buttons. This is the code in c++ which i should modify class BtnEventHandler { public: HRESULT OnClick(IXRDependencyObject* source,XRMouseButtonEventArgs* args) { RETAILMSG(1,(L"Browser event")); Execute(L"\\Windows\\iesample.exe",L""); return S_OK; } }; // entry point for the application. INT WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance, LPWSTR lpCmdLine,int nCmdShow) { PrintMessage(); int exitCode = -1; HRESULT hr = S_OK; if (!XamlRuntimeInitialize()) return -1; HRESULT retcode; IXRApplicationPtr app; if (FAILED(retcode=GetXRApplicationInstance(&app))) return -1; if (FAILED(retcode=app->AddResourceModule(hInstance))) return -1; XRWindowCreateParams wp; ZeroMemory(&wp, sizeof(XRWindowCreateParams)); wp.Style = WS_OVERLAPPED; wp.pTitle = L"Bounce Test"; wp.Left = 0; wp.Top = 0; XRXamlSource xamlsrc; xamlsrc.SetResource(hInstance,TEXT("XAML"),MAKEINTRESOURCE(IDR_XAML1)); IXRVisualHostPtr vhost; if (FAILED(retcode=app->CreateHostFromXaml(&xamlsrc, &wp, &vhost))) return -1; IXRFrameworkElementPtr root; if (FAILED(retcode=vhost->GetRootElement(&root))) return -1; IXRButtonBasePtr btn; if (FAILED(retcode=root->FindName(TEXT("BrowserButton"), &btn))) return -1; IXRDelegate<XRMouseButtonEventArgs>* clickdelegate; BtnEventHandler handler; if(FAILED(retcode=CreateDelegate (&handler,&BtnEventHandler::OnClick,&clickdelegate))) return -1; if (FAILED(retcode=btn->AddClickEventHandler(clickdelegate))) return -1; UINT exitcode; if (FAILED(retcode=vhost->StartDialog(&exitcode))) return -1; return exitCode; } I have to add event handler for both the button so that on emulator whenever i click on any one of the button i should be able to launch the respective applications.

Grails GORM on multiple Forms

- by Fabien Barbier

Usually I'm using One-to-many relationship by this way : class Subject { static hasMany = [ crfs : Crf ] String name ... } class Crf { String title String info ... } I can extend this relationship to others domains, Ex : static hasMany = [ crfs : Crf, crfb : CrfBlood ...] But in my case I have to link the Subject domain to 30 others domains, maybe more...(ex : CrfBlood, CrfMedical, crfFamily, etc...). What domain model implementation should I use in my case ? I would like to keep the dynamic finders usability in my project.

How to prevent parallel builds per build configuration across multiple Build Agents

- by vanslly

I have many build configurations in TeamCity, each servicing a large project. In the past if a build is kicked off the Build Agent could be busy for up to 20min! In order to improve throughput I installed a second Build Agent on the same machine such that if a build run is kicked off by say Build Agent 1 and it is busy for 20min and someone from another project makes a change then Build Agent 2 can do the build for the other project without needing to wait on the current build run to finish. All was well until two successive check-ins resulted in both Build Agents running a build for a single build configuration in parallel. Since some resources are shared, IIS directories & databases, I don't want a single build configuration to run on both Build Agents in parallel. How can I ensure a build isn't triggered if a build is currently running for that build configuration on a different build agent? One way seems to involve environmental variables and ensuring a 50/50 split by Build Agent in terms of build configuration compatibility, but that seems a little clunky.

Saving multiple objects in a single call in rails

- by CaptnCraig

I have a method in rails that is doing something like this: a = Foo.new("bar") a.save b = Foo.new("baz") b.save ... x = Foo.new("123", :parent_id => a.id) x.save ... z = Foo.new("zxy", :parent_id => b.id) z.save The problem is this takes longer and longer the more entities I add. I suspect this is because it has to hit the database for every record. Since they are nested, I know I can't save the children before the parents are saved, but I would like to save all of the parents at once, and then all of the children. It would be nice to do something like: a = Foo.new("bar") b = Foo.new("baz") ... saveall(a,b,...) x = Foo.new("123", :parent_id => a.id) ... z = Foo.new("zxy", :parent_id => b.id) saveall(x,...,z) That would do it all in only two database hits. Is there an easy way to do this in rails, or am I stuck doing it one at a time?

Storing multiple inputs with the same name in a CodeIgniter session

- by Joshua Cody

I've posted this in the CodeIgniter forum and exhausted the forum search engine as well, so apologies if cross-posting is frowned upon. Essentially, I've got a single input, set up as <input type="text" name="goal">. At a user's request, they may add another goal, which throws a duplicate to the DOM. What I need to do is grab these values in my CodeIgniter controller and store them in a session variable. My controller is currently constructed thusly: function goalsAdd(){ $meeting_title = $this->input->post('topic'); $meeting_hours = $this->input->post('hours'); $meeting_minutes = $this->input->post('minutes'); $meeting_goals = $this->input->post('goal'); $meeting_time = $meeting_hours . ":" . $meeting_minutes; $sessionData = array( 'totaltime' => $meeting_time, 'title' => $meeting_title, 'goals' => $meeting_goals ); $this->session->set_userdata($sessionData); $this->load->view('test', $sessionData); } Currently, obviously, my controller gets the value of each input, writing over previous values in its wake, leaving only a string of the final value. I need to store these, however, so I can print them on a subsequent page. What I imagine I'd love to do is extend the input class to be able to call $this-input-posts('goal'). Eventually I will need to store other arrays to session values. But I'm totally open to implementation suggestion. Thanks so much for any help you can give.
