  • Cross-browser curved borders

    - by Gandalf StormCrow
    What is the best way to achieve cross-browser(ff,ie6,chrome,opera,safari) curved corners on a div. I found this article http://jonraasch.com/blog/css-rounded-corners-in-all-browsers and I've followed instructions step by step multiple times, here is my css : #content_wrapper{ -moz-border-radius:25px 25px 25px 25px; -webkit-border-radius: 25px; -khtml-border-radius: 25px; border-radius: 25px; background-color:#F2DADC; border:25px solid #ECD3D5; height:780px; opacity:0.7; width:747px; margin:0px auto; position:relative; display:block; zoom:1; } <!--[if lte IE 8]> <style> #content_wrapper{ behavior: url(template/css/border-radius.htc); border-radius: 20px; } </style> <![endif]--> Can somebody point me what am I doing wrong or is there a better way to achieve the same effect, its working in all browsers except in IE

  • how to insert excel-2003 values into SQL2005 database?

    - by vas
    Are there any rules / guidelines for DATA form XLS sheets to be inserted into SQL- DB? I have a group of Excel templates in 2005.Each concerned cell in Excel template is named. When Excel sheets are filled, saved and submitted , the values are transferred to the database. Excel sheets have names for various cells that are to b e filled by the user EX:- for the total number of Milk in the Beginning a given month , there is an Excel Cell Named "mtsBpiPTR180" Total number of Milk in the Ending a given month , there is an Excel Cell Named **"mtsEpiPTR180"** I have added 2 new cells , named "mtsBpiPTR180PA" and "mtsEpiPTR180PA". Now I try to upload the Excel File. But I AM UNABLE TO SEE MY FILLED DATA FROM "mtsBpiPTR180PA" and "mtsEpiPTR180PA" INTO THE RELATED DB/table. The above 2 are empty in the DB/table, even though I have filled them and successfully filed the Excel sheets Now no matter how much I search in the DB/stored procs i am unable to the ACTUAL STORED PROC or how the Data form Excel sheet is inserted into Tables WHERE DATA FROM XLS is inserted into DB. So was wondering:- Are there any rules / guidelines for DATA form XLS sheets to be inserted into SQL- DB?

  • Dynamic content in a Gridview

    - by mariki
    I have a gridview with couple of columns,I want to achieve the following: If user is NOT authorized display normal columns. If user IS authorized: set mouseover event for first column text and display some buttons (that are not available for NOT authorized users) in a second column when user hover over(using javascript) the first column. I am have 2 difficulties: The first one where and when should I create the buttons? I have 2 options, I can create those button on design time, in gridviews template and just set Visible value to false and then in codebehind set it to true if user is authorized. The second option would be creating this buttons dynamically in gridview_RowCreated event (or any other event) if user is authorized. The Second difficulty is setting the javascript event to show the buttons, the event should be added only if user is authorized! Note that event and buttons should have some kind of id match for Javascript function to know what should it hide/unhide when event is triggered. What should I do, what is the best practice? I know this is a long question, but please try to help :)

  • C++ new memory allocation fragmentation

    - by tamulj
    I was trying to look at the behavior of the new allocator and why it doesn't place data contiguously. My code: struct ci { char c; int i; } template <typename T> void memTest() { T * pLast = new T(); for(int i = 0; i < 20; ++i) { T * pNew = new T(); cout << (pNew - pLast) << " "; pLast = pNew; } } So I ran this with char, int, ci. Most allocations were a fixed length from the last, sometimes there were odd jumps from one available block to another. sizeof(char) : 1 Average Jump: 64 bytes sizeof(int): 4 Average Jump: 16 sizeof(ci): 8 (int has to be placed on a 4 byte align) Average Jump: 9 Can anyone explain why the allocator is fragmenting memory like this? Also why is the jump for char so much larger then ints and a structure that contains both an int and char.

  • View Source and Chrome Developer Tools showing different output

    - by patricksweeney
    I have a page located here. Viewing it in Chrome and Firefox show a really small h1 title, and also it changes color as if it is a link. The template that generates everything looks exactly how it should be. When diagnosing the issue, the relevant section of code looks like this when I go to view source: <div class="page-heading"> <h1>Title Here</h1> </div> However, when I go to view it in Chrome's Developer tools, it is throwing in extraneous malformed anchor tags, which is obviously causing the hovering behavior. This is what it looks like to the dev tools: <div class="page-heading"> <h1> <a style="font-family: arial; font-size: 9px" <="" a="">Title Here</a> </h1> </div> In addition, when viewing a local copy of the site, the output shown in the dev tools is the same as viewing the source and they both render correctly locally. Oddly enough, all version of IE render it correctly. The current version of both Chrome and Firefox both render it weirdly. Initially I thought it may be a user agent stylesheet problem, but if anything the CSS is fine, it's the HTML that is malformed.

  • Where to turn upon realizing I can't program my way out of a paper bag?

    - by luminarious
    I have no job and just enough money to get by until April or so. While looking for work, I figured I might as well go through with a pet project, a browser based card game. Make it nice and free, collect donations and maybe earn enough for a movie ticket to escape reality for a while. I have dabbled in web development a bit. I can make simple stuff happen with JS/PHP if I follow tutorials. I designed my own art blog's template - http://luminarious.tumblr.com. I can visualise the game working in my head, flowcharts and everything. But then I tried to go deeper with Javascript and almost had an aneurysm before understanding what a closure is. Wether I suck at learning, have ADD or fail epically at productivity, I have not got much done. Coming up with ideas, screen mock-ups and so forth was very enjoyable, but actual implementation.. not so much. In fact, I cry a bit every time I think about the time someone competent could have finished this in. I'd like to excuse myself with my ENTP personality type, but that hardly solves anything. Rather, I'd like to know to get from A (bunch of ideas with little semblance to a web app) to B (something to proudly show others) while being unable to pay anyone? Are there any secret techniques for learning? Is there any way to get mentoring or code review? Is there anyone with too much free time willing to code for me? How to trust someone to not steal my code when I ask for assistance? Is there anything I should have asked instead of any of those?

  • How to use a divider in a navigation with list elements?

    - by Kris
    I want to create a navigation which got divider between each list element. Here is a simple HTML/CSS Code/Template : <nav> <ul> <li><a href="#">A</a></li> <li><a href="#">B</a></li> <li><a href="#">C</a></li> <li><a href="#">D</a></li> <li><a href="#">E</a></li> </ul> </nav> nav ul { list-style:none; float:right; } nav ul li { float:left; padding-left:10px; } nav ul li a { color:#111; font-family:Verdana; font-size:15px; text-decoration:none; } nav ul li a:hover { color:#9F3039; } so just a simple looking navigation which floats from the right side on a logo which is not displayed in the code here. Now I want to at devider between each link - I know I could do it with border-right and just use another class on my last listelement which set the border-right off, BUT I want to use a special kind of divider - an image. How can I do it best ?

  • Domain model for an online WYSYWG webpage generator / runtime

    - by CharlieBrown
    Hi all, I'm using C#, MVC, NHibernate and StructureMap as my IoC container, and need some ideas regarding my domain model. The application I'm working has two parts: an Authoring part and a Runtime part. The idea is to allow the user to create a webpage in Authoring (mostly a form actually) by choosing from a set of predefined controls. That webpage will be later used as a form in a call center environment (Runtime part), or may be used in an intranet portal, etc. Basically something similar to what a CMS would do. The difference is, of course, that the webpage/form the author generates will be used and fulfilled in runtime, and that authros should be able to freely create the webpage they want without limitations. I have a draft working model that allows a RunController to iterate over the ScriptPage (my class for the "generated webpage") Controls collection and uses partial views to render each of them. Works kind of fine. Basically I have a common ScriptControl class, and then I can create for example a TextInputControl or a DropDownControl by inheriting from that base class. I can also figure out the Authoring part of the app, although that will surely be fun in itself for sure. :) The biggest problem I have now is persistance. In order to be flexible, I want to be able to add more controls, and template controls (think of an Address composite control) in sepparate DLLs, so I think having a relational model that handles very possible control is not the way to go. My current thinking is using a kind of ObjectStore: binary-serializing the ScriptPage object that contains the List collection and deserializing at Runtime, but I'm not sure how good will it work with NHibernate and how good the performance will be. Serializing a small "page" with 10 controls results in 7964 bytes, for example. Any ideas out there? Thanks in advance, excuse the length. ;)

  • Pointer mysteriously moves

    - by Armen Ablak
    Hi, I have this code for Node rotation and in a line which is marked something happens and I don't really know what and why :). //Test case 30 \ 16 / 29 RotationRight(node->mParent); //call template<class T> void SplayTree<T>::RotationRight(SplayNode<T> *&node) const { SplayNode<T> *left = node->mLeft; SplayNode<T> *parent = node->mParent; node->mLeft = left->mRight; if(left->HasRight()) left->mRight->mParent = node; left->mRight = node; //node in this line points to 0x00445198 {30} left->mParent = node->mParent; //and in this line it points to 0x00444fb8 {16} (node, not node->mParent) node->mParent = left; node = left; } Well, left-mParent points to node also, so I basically do node = node-mParent. The problem is I can't find a work around - how to unpin in from node and change it's pointing address without changing it's.

  • Why am I needing to click twice on a WPF listbox item in order to fire a command?

    - by Donal
    Hi, I'm trying to make a standard WPF listbox be dynamically filled, and for each item in the list box to launch a command when clicked. Currently I have a working listbox, which can be filled and each item will fire the correct command, but in order to fire the command I have to click the list item twice. i.e, Click once to select the item, then click on the actual text to fire the command. As the list is dynamically created, I had to create a data template for the list items: <ListBox.ItemTemplate> <DataTemplate> <TextBlock Margin="4,2,4,2"> <Hyperlink TextDecorations="None" Command="MyCommands:CommandsRegistry.OpenPanel"> <TextBlock Text="{Binding}" Margin="4,2,4,2"/> </Hyperlink> </TextBlock> </DataTemplate> </ListBox.ItemTemplate> Basically, how do I remove the need to click twice? I have tried to use event triggers to fire the click event on the hyperlink element when the list box item is selected, but I can't get it to work. Or, is there a better approach to dynamically fill a listbox and attach commands to each list item? Thanks

    Hi! This is my big problem. This script put the information to a table. function handleAccountFeed(result) { var entries = result.feed.getEntries(); var outputTable = ['<table><tr>', '<th>Account Name</th>', '<th>Profile Name</th>', '<th>Profile ID</th>', '<th>Table Id</th></tr>']; for (var i = 0, entry; entry = entries[i]; ++i) { var row = [ entry.getPropertyValue('ga:AccountName'), entry.getTitle().getText(), entry.getPropertyValue('ga:ProfileId'), entry.getTableId().getValue() ].join('</td><td>'); outputTable.push('<tr><td>', row, '</td></tr>'); } outputTable.push('</table>'); document.getElementById('outputDiv').innerHTML = outputTable.join(''); } I've got an own SMARTY template, which makes a table: <table id="stuffs"> <tbody> {section name=i loop=$ownsites} <tr><td>{$ownsites[i].id}</td><td>{$ownsites[i].domain}</td><td>PLACE</td></tr> {/section} <tbody> </table> I'd like to put the TableId (getTableId().getValue()) to that row's PLACE where {$ownsites[i].domain} is equal to the jquery row's Title (getTitle().getText()) How can i do this within this jQuery script?

  • Why would 1.000 subforms in a db be a bad idea?

    - by KlaymenDK
    Warm-up I'm trying to come up with a good way to implement customized document forms. It's for a tool to request access to applications; each application will want to ask its own specific questions. The thing is, we have one kind of (common) user who needs to fill in and submit documents based on templates, and another kind of (super) user who needs to be able to define what each template needs to contain. One implementation option would be to use a form (with the basic mandatory stuff), and have that form dynamically include a subform appropriate to the specific task at hand. The gist of the matter is that we could (=will!) quite easily end up having many hundreds of different subforms! (NB. These subforms will be maintained in an automated manner, but that is another topic that may be considered outside the scope of this Question.) Question It's common knowledge that having a lot of views in a Notes database is Bad Thing. But has anyone tried pushing the number of forms or subforms and made any experiences regarding performance?

  • Has anyone used ever Mangoslick from themeforest?

    - by bonesnatch
    I was assigned to integrate MangoSlick theme to our current admin panel, Its a jQuery, Slick(?) and Responsive template. First, let me explain how the API goes In the documentation, it only says this is the only way data-[options]=[value] Example: If I wanna make a progress bar I can use this format <div class="progress"> <div class="bar" data-title="[title]" data-value="[value]" data-max="[max]" data-format="[format string]"></div> </div> so filling-in values <div class="progress"> <div class="bar" data-title="Space" data-value="1285" data-max="5120" data-format="0,0 MB"></div> </div> I will have this as output Now, the main question is when I use jQuery attr() to change the attribute values for data-title, data-max, data-value and data-format. Why is it not working? <script> var jq = $.noConflict(); jq(document).ready(function(){ jq('#bokz').attr("data-title", "No Space"); }); </script> Using the script above and inspect element in chrome the values are changed but not in the progressbar Some of you may have some ideas on this? Any help/suggestion would be very much appreciated.

  • How can I use "PHP Simple HTML DOM Parser" to get the contents of an <h1></h1> tag?

    - by KeriLynn
    I'm new to PHP =) Right now I am using PHP includes for my site template. I have my header, containing all my <head></head> info. What I want to do is write a code that will take the contents of the <h1></h1> tag from the page, and echo it into the <title></title> tag in my header.php include. I got the PHP Simple HTML DOM Parser from here: http://simplehtmldom.sourceforge.net/, and I found a code (I forget where in all my googling) that goes like this: <?php $url = (!empty($_SERVER['HTTPS'])) ? "https://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'] : "http://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']; $html = file_get_html('http://www.google.com/'); foreach($html->find('#content h1') as $element){ echo $element->plaintext;} ?> That I think is supposed to echo the h1 tag contents? Like I said, I'm new to PHP and I only know the basics, and I don't know really know any OOP (yet), so I'm sorry if I'm asking a dumb question. It looks like it's getting the current page, then putting the contents of the h1 tag into the variable $element, and then echoing it. But nothing happens when I put it into my page. Can anyone help me with what I'm doing wrong? Thank you for reading!! =)

  • Django: getting the list of related records for a list of objects

    - by Silver Light
    Hello! I have two models related one-to many: class Person(models.Model): name = models.CharField(max_length=255); surname = models.CharField(max_length=255); age = models.IntegerField(); class Dog(models.Model): name = models.CharField(max_length=255); owner = models.ForeignKey('Person'); I want to output a list of persons below each person a list of dogs he has. Here's how I can do it: in view: persons = Person.objects.all()[0:100]; in template: {% for p in persons %} {{ p.name }} has dogs:<br /> {% for d in persons.dog_set.all %} - {{ d.name }}<br /> {% endfor %} {% endfor %} But if I do it like that, Django will execute 101 SQL queries which is very inefficient. I tried to make a custom manager, which will get all the persons, then all the dogs and links them in python, but then I can't use paginator (my another question: http://stackoverflow.com/questions/2532475/django-paginator-raw-sql-query ) and it looks quite ugly. Is there a more graceful way doing this?

  • Ways to support manually executed tests? (that can be used on a Mac)

    - by Rinzwind
    Are there any tools that can be used on a Mac to support manually executed tests? I have a number of tests that I'm executing manually and which I'm currently documenting using merely a plain text file. "Tools" can be interpreted rather loosely here, anything that's a step up from the plain text file would be useful: a template for some suitable application, supporting AppleScript scripts, a web-based system, a full-blown application ... Some things that would be great to have better support for (see also the example below): Checking off each step while you're manually executing the test. Showing the next step(s) in a small window that is always kept in front of all other windows. Automatically updating the 'last tested' and 'using svn revision' info. Keeping a record of all previous testing rounds (not just the last one). ... Any suggestions for any such "tools" that can be used on a Mac? An example (faked) entry from the plain text file to give you a better idea of what I'm looking for: - Check that exported web pages render properly in Safari. Last tested: 2010-03-24 Using SVN revision: 1000 Steps: - Open a new document. - Add some items to the document. - Export the document to a web page "Test.html" in a new folder "Export Test" on the Desktop. - Open the web page in Safari, script: tell application "Finder" open file "Test.html" of folder "Export Test" of desktop end tell Expected results: - The web page should appear properly with all items shown. Clean up steps: - Remove the folder "Export Test" from the Desktop. ( Note: for those unaware, the snippet of AppleScript in the above can be executed from most text editing applications through the Services menu by selecting the snippet and using: the application menu Services Script Editor Run as AppleScript. This is quite useful to automate some steps for tests that are difficult to automate as a whole. )

  • CSS H4 hover style

    - by user1750613
    I tried many css from other places and stackoverflow, but somehow I can not make it done. I'm very new to css, and using Joomla and a template. I'm using custom.css folder for certain customizations on style. Here is I want to do: I want to style h4 when it is a link. For example, I'm creating a custom html module, have a list in the content. And in the content I'm giving each, h5 style, and a link to it to a certain page in the site. What I want to achieve is to have this list with color blue. And when mouse over-hover to have underline and still the same color. And when clicked back to the original position with no underline and no color change. (the same color in every situation, just underline when you are over it.) I tried these h5, h5 a, h5 a: hover, h5 .contentheading a, and so on... In one instance, it was working with : h5 { font-family: arial, sans-serif; font-size: 1.3em; font-weight: bold; } h5 a { color: #0088CC; } h5 a: hover { color: #0088CC; text-decoration: underline; } As I read I should use 'a' when the heading is a link. But now something is overriding it, I'm completely lost now. I see a:hover style in the inspection. I want to use this h5 in several content (in custom modules) when I want to style a content as a list to links. And I thought it will be practical to have one heading with a certain style so that I can use it with flexibility. Thanks a lot, any help will be great : )

  • Can I automate a loop query based on category with the page's title?

    - by jordaninternets
    To explain further, I need to get a page to display posts from a specific category. I want to automate this process so I don't have to make a template for each category. How would I do that? (keep in mind the person I'm building this is for has no coding experience.) The only way I could think off from the top of my head is to use the title or slug. So if the category is named the same thing as the slug, could I filter by category using the slug? Maybe this isn't the best way... what should I do? This is what I came up with, but it doesn't work, I'm sure due to improper use on may part, but I've been pouring over the WP codex and Google with no avail to tell me my problem. <?php $paged = (get_query_var('paged')) ? get_query_var('paged') : 1; $args= array( 'orderby' => 'date', 'order' => 'ASC', 'paged' => $paged, 'category_name' => echo the_title('\'','\'',) ); query_posts($args); ?>

  • ASP.NET Custom/User Control With Children

    - by Bob Fincheimer
    I want a create a custom/user control that has children (NOT a template control). For Example, I want my control to have the following markup: <div runat="server" id="div"> <label runat="server" id="label"></label> <div class="field"> <!-- INSERT CHILDREN HERE --> </div> </div> and when I want to use it on a page I simply: <ctr:MyUserControl runat="server" ID="myControl"> <span>This is a child</span> <div>And another <b>child</b> </ctr:MyUserControl> The child controls inside my user control will be inserted into my user control somewhere. What is the best way to accomplish this. The functionality is similar to a asp:PlaceHolder but I want to add a couple more options as well as additional markup and the such. Also the child controls still need to be able to be accessed by the page.

  • Considering moving from Java/Spring MVC to Grails

    - by MDS
    I'm currently using Java & Spring (MVC) to create a webapp, and I'm considering moving to Grails. I'd appreciate feedback/insight on the following: I have multiple application contexts in the current Java/Spring webapp that I load through the web.xml ContextLoaderListener; is it possible to have multiple application contexts in Grails? If, yes, how? This webapp extensively uses a CXF restful web service and the current Java/Spring webapp uses the bundled CXF HTTP client. Can I continue to use the (Java) CXF HTTP Client in Grails? I implemented Spring Security using a custom implementation of UserDetails and UserDetailsService, can I re-use these implementations in Grails "as is" or must I re-implement them? There is an instance where I've relied on Spring's jdbc template (rather than the available ORM) and an additional data source I defined in app context, can I re-use this in Grails? I plan on using Maven as the project management tool; are there any issues of using Maven with Grails where there is a combination of groovy and java?

  • fastest public web app framework for quick DB apps?

    - by Steve Eisner
    I'd like to pick up a new tech for my toolbox - something for rapid prototyping of web apps. Brief requirements: public access (not hosted on my machine) - like Google's appengine, etc no tricky configuration necessary to build a simple web app host DB access (small storage provided) including some kind of SQLish query language easy front end HTML templating ability to access as a JSON service C# or Java,PHP or Python - or a fun new language to learn is OK free! An example app, very simple: render an AJAXy editable (add/delete/edit/drag) list of rich-data list items via some template language, so I can quickly mock up a UI for a client. ie. I can do most of the work client-side, but need convenient back end to handle the permanent storage. (In fact I suppose it doesn't even need HTML templating if I can directly access a DB via AJAX calls.) I realize this is a bit vague but am wondering if anyone has recommendations. A Rails host might be best for this (but probably not free) or maybe App Engine, or some other choice I'm not aware of? I've been doing everything with heavyweight servers (ASP.NET etc) for so long that I'm just not up on the latest... Thanks - I'll follow up on comments if this isn't clear enough :)

  • What am I doing wrong with my ItemsControl & databinding?

    - by Joel
    I'm reworking my simple hex editor to practice using what I've recently learned about data binding in WPF. I'm not sure what I'm doing wrong here. As I understand it, for each byte in the collection "backend" (inherits from ObservableCollection), my ItemsControl should apply the DataTemplate under resources. This template is just a textbox with a binding to a value converter. So I'm expecting to see a row of textboxes, each containing a string representation of one byte. When I use this XAML, all I get is a single line of uneditable text, which as far as I can tell doesn't use a textbox. What am I doing wrong? I've pasted my XAML in below, with the irrelevant parts (Menu declaration, schema, etc) removed. <Window ...> <Window.Resources> <local:Backend x:Key="backend" /> <local:ByteConverter x:Key="byteConverter" /> <DataTemplate DataType="byte"> <TextBox Text="{Binding Converter={StaticResource byteConverter}}" /> </DataTemplate> </Window.Resources> <StackPanel> <ItemsControl ItemsSource="{Binding Source={StaticResource backend}}"> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <WrapPanel /> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> </ItemsControl> </StackPanel> </Window>

    Here is my simple app: <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:app="clr-namespace:WpfApplication1" Title="Window1" Height="300" Width="300"> <Window.Resources> <Style x:Key="Test"> <Setter Property="Button.Template"> <Setter.Value> <ControlTemplate> <Border BorderBrush="Blue" BorderThickness="3" Background="Black" CornerRadius="{Binding app:Extras.CornerRadius}" > </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> </Window.Resources> <Grid> <Button Height="23" HorizontalAlignment="Left" Margin="29,26,0,0" Name="button1" VerticalAlignment="Top" Width="75" app:Extras.CornerRadius="10" Style="{StaticResource Test}" >Button</Button> </Grid> </Window> Here is my AttachedPropery: namespace WpfApplication1 { public class Extras { public static readonly DependencyProperty CornerRadiusProperty = DependencyProperty.RegisterAttached( "CornerRadius", typeof(double), typeof(Button), new FrameworkPropertyMetadata(1.0d, FrameworkPropertyMetadataOptions.AffectsRender) ); public static void SetCornerRadius(UIElement element, double value) { element.SetValue(CornerRadiusProperty, value); } public static double GetCornerRadius(UIElement element) { return (double)element.GetValue(CornerRadiusProperty); } } } CornerRadius="{Binding app:Extras.CornerRadius}" this of course doesn't work. so how can I get value from here app:Extras.CornerRadius="10" thanks in advance!

  • C++ - Where to throw exception?

    - by HardCoder1986
    Hello! I have some kind of an ideological question, so: Suppose I have some templated function template <typename Stream> void Foo(Stream& stream, Object& object) { ... } which does something with this object and the stream (for example, serializes that object to the stream or something like that). Let's say I also add some plain wrappers like (and let's say the number of these wrappers equals 2 or 3): void FooToFile(const std::string& filename, Object& object) { std::ifstream stream(filename.c_str()); Foo(stream, object); } So, my question is: Where in this case (ideologically) should I throw the exception if my stream is bad? Should I do this in each wrapper or just move that check to my Foo, so that it's body would look like if (!foo.good()) throw (something); // Perform ordinary actions I understand that this may be not the most important part of coding and these solutions are actually equal, but I just wan't to know "the proper" way to implement this. Thank you.
