  • Render ViewComponent from another component codebehind

    - by George Polevoy
    I'm trying to render a component from withing another component. public override void Render() // ... var block = new Block(); block.Init(EngineContext, Context); block.Render(); // ... } The problem is that Block component can't find it's template. ResourceProcessingException Message: Unable to process resource 'components\CustomReportComponentComponent\default.vm': Resource could not be located I guess, other problems can arise because the component is not properly initialized. Is it possible to initialize a component from within another component's Render method, so it renders just as if called from a .vm?

  • What exactly does "adopt a protocol" mean in the Objective-C / Cocoa documentation ?

    - by driis
    I am a C# developer getting started on Objective-C / Cocoa Touch programming. I think I might have gotten some terms wrong because I keep thinking about them "the C# way". Specifically, I have come around the term "protocol" in various documentation and tutorials. In Objective-C, what exactly is a protocol ? Can it be compared to a C# interface ? Is the following declaration the same as saying "The class is implementing the protocol UITextFieldDelegate" ? Or is UITextFieldDelegate to be compared with a generic type parameter in C# ? @interface MyViewController : UIViewController <UITextFieldDelegate> { }

  • Accessing a webpage in C++

    - by wyatt
    Is there a good, simple library which allows C++ to load a webpage? I just want to grab the source as text. I'm not using any IDE or significant library, just straight command line. Tangentially, is there something fundamental I'm missing about programming in C++? I would think any language in common use today would have droves of web-based functionality, being so central to computer usage, but I can find next to no discussion on how to accomplish it. I realise C++ significantly predates the modern internet, so it lacking any core ability in the regard is reasonable, but the fact that relevant libraries seem so sparse is baffling. Thanks for your help.

  • Programmatic Reaction to Receiving New Email

    - by vicatcu
    I'm interested in automating some reactive work I do when receiving certain emails in one of my email accounts. What I would like to have happen is: On receipt of new email in the account If the new email passes the "Need to React" criteria (based on body content and subject line) 3a. Scrape some content out of the email body and subject lines 3b. Populate a template form (e.g. Excel spreadsheet) with the scraped data 3c. Print the populated form and save the populated form in some folder (e.g. as a pdf) What's the best (defined as easiest to implement by myself) approach / combination of technologies for achieving this automation?

  • jQuery selector loads images from server

    - by Guillaume
    Hi! here is the code: <script type="text/javascript"> var ajax_data = '<ul id="b-cmu-rgt-list-videos"><li><a href="{video.url}" '+ 'title="{video.title.strip}"><img src="{video.image}" '+ 'alt="{video.title.strip}" /><span>{video.title}</span></a></li></ul>'; var my_img = $(ajax_data).find('img'); </script>` ajax_data is data from a JS template engine where I need to get some part of it. The problem is that jQuery does a GET on the img src={video.image}: GET /test/%7Bvideo.image%7D HTTP/1.1 (on Firefox Live HTTP headers). This GET generates a 404 from the server. Any clues on how to solve this? Thanks a lot :)

  • How do i use 'auto' in C++ (C++0x) ?

  • Looking for ideas on automatically arranging a set of objects (furniture) in a virtual room in AS3

    - by raf
    First of all, I don't want to visually arrange 3D models dragging them with the mouse, all I want is: Given a room of certain dimensions (L,W,H) and given a set of elements like beds, chairs, etc (with L,W,H dimensions, of course) I want to automatically arrange those elements to take advantage of the space as much as I can. So I want to be able to put as much furniture as I can in a given room. At the end I need to represent the arranged items visually, inside the room. My first thought was to use an array of items and sorting it with array.sortOn(["l","w","h"] Array.NUMERIC) and then define a gap between the objects and make the maths to put the objects one next to another, etc. but that isn't a good approach because some items may be placed on top of another ones (boxes of the same size, boxes on top of tables, etc). I really don't have experience on 3D programming, that's why I'm asking for help. Thanks in advance.

  • Using custom HTML attributes for JavaScript purposes?

    - by user1103990
    One of my colleagues doesn't like to use HTML classes and ids for javascript/jQuery purpose. Therefore I've seen that he had created custom html attribute such as <div id="myid" class="cssClasses ..." [some-purpose-id]="mycustomId">...</div> I asked him if it was really a good idea and he replied that he considers that classes and Ids should be reserved for styling. Personally, I would have used classes. Some classes would have been used for styling, and some other classes would have been used for programming (jQuery selectors). The idea is to keep things appart also. And of course jQuery could set styling classes but if possible not use them for selection. Of course I also use id when appropriate but since an id is unique on a page, I like to do generic stuff using classes. I would like to know you opinions on the better approach (if there is one). Thank you.

  • generating function arguments in java

    - by aloishis89
    I'm very new to java and am working on my first Android app. I am using the webview demo as a template. I am trying to generate a random integer between 1 and 12 and then call a certain javascript function based on the result. Here's what I have: int number = 1 + (int)(Math.random() * ((12 - 1) + 1)); number = (int) Math.floor(number); String nextQuote = "javascript:wave" + number + "()"; mWebView.loadUrl(nextQuote); So mWebView.loadUrl(nextQuote) will be the same as something like mWebView.loadUrl("javascript:wave1()") I just want to know if what I have here is correct and will work the way I think it will. The application isn't responding as expected and I suspect this bit of code is the culprit.

  • Open two new tabs using Javascript

    - by Permana
    I have this situation: There are a login page with a login form (form action is $_SERVER['PHP_SELF']). When user login, it will check what application the user can access and open all the application that available for that user in new tab. If user can access application (for example) 'Docs' and 'Sites', it will open 2 tabs. I Open new tab using window.open('app1.html','_newhtml');, some people say that it only works in Firefox. It's OK, no big deal for me. The problem is, It only open 1 tab, although I write it 2 times window.open('app1.html','_newhtml'); window.open('app2.html','_newhtml'); How can I open 2 tabs? are there any hacks from server side or client side programming?

  • How to replace a codebehind method with an aspx method using ternary operator

    - by user466663
    I have an asp:hyperlink control as part of a gridview template. The code in the aspx page is given below: asp:HyperLink runat="server" ID="lnkEdit" ToolTip="Edit article" NavigateUrl='<%# GetUrl(Eval("ID").ToString(), Eval("CategoryID").ToString()) %' ImageUrl="~/Images/Edit.gif" The NavigateUrl value is obtained from the codebehind method GetUrl(string, string). The code works fine and is as follows: protected string GetUrl(string id, string categoryID) { var CategoryID = string.Empty; if (!String.IsNullOrEmpty(Request.QueryString["CatID"])) { CategoryID = Request.QueryString["CatID"].ToString(); } else if (!String.IsNullOrEmpty(categoryID)) { CategoryID = categoryID; } return "~/TBSArticles/WriteOrEditArticle.aspx?ID=" + id + "&CatID=" + CategoryID; } I want to replace the code behind method by using a ternary operator within the aspx page. I tried something like below, but didn't work: asp:HyperLink runat="server" ID="lnkEdit" ToolTip="Edit article" NavigateUrl='<%# "~/TBSArticles/WriteOrEditArticle.aspx?ID=" + Eval("ID") + "&CatID=" + Eval(this.Request.QueryString["CatID"].ToString()) != ""? this.Request.QueryString["CatID"] : Eval("CategoryID")) %' ImageUrl="~/Images/Edit.gif" Any help will be greatly appreciated. Thanks

  • Python design mistakes

    - by Andrea
    A while ago, when I was learning Javascript, I studied Javascript: the good parts, and I particularly enjoyed the chapters on the bad and the ugly parts. Of course, I did not agree with everything, as summing up the design defects of a programming language is to a certain extent subjective - although, for instance, I guess everyone would agree that the keyword with was a mistake in Javascript. Nevertheless, I find it useful to read such reviews: even if one does not agree, there is a lot to learn. Is there a blog entry or some book describing design mistakes for Python? For instance I guess some people would count the lack of tail call optimization a mistake; there may be other issues (or non-issues) which are worth learning about.

  • Alternative to jQuery .data()?

    - by thebossman
    I'm a big fan of jQuery's .data() method, but I can't always use it. Often times I am rendering html templates that I pass via AJAX and I need to attach metadata to each of the elements in the template. For example: <ul> {% for item in itemlist %} <li metadata="{{ item.metadata }}">{{ item.name }}</li> {% endfor %} </ul> I know attaching attributes to store data is bad practice (and it might not even work in older versions of IE). What is the best practice? Is there a good alternative to this method?

  • Making an asynchronous interface appear synchronous to mod_python users

    - by Trey
    I have a Python-driven web interface powered by Apache 2.2 with mod_python and Python 2.4. I need to make an asynchronous process appear synchronous to users of this web interface. When users access one module on this website: An external SOAP interface will be contacted with a unique identifier and will respond with a number N The external interface will respond asynchronously by contacting a SOAP server on my machine between 1 and 10 times (the number N tells us how many responses we will receive) I need to somehow aggregate these responses and pass them to the original module which will display the information back to the user. The goal is to make the process appear synchronous to the user. What is the best way to handle this synchronization issue? Is this something Twisted would be well-suited for? I am not restricting myself to Python for the solution, though it is preferred because everything else on the server is in Python. I prefer a solution that is both scalable and will take a minimal amount of programming time (though I understand that these attributes are somewhat at odds).

  • Where's the definitive resource online about how to carry out Agile development?

    - by jdk
    I want to start Agile practices in a team. I'm assuming the information is available for free online about how to specifically carry it out. Online I can locate the manifesto, the alliances and corporations involved but where is the actual central guide or root instruction set about how to do it? (Maybe the practices themselves are more ethereal or subjective than I expect and it's found in multiple places?) Edit to summarize solutions: Agile is a concept so that's what's to be found online about it. However specific processes or methods of Agile development have been created like Scrum and Extreme programming to provide concrete solutions to teams who want to adopt Agile and reap its proposed benefits. Find the shoe (or method) that fits best. Maybe create it. If looking for solutions online to implement Agile development in your organization or for your project, seek out the specific methods too and decide among them.

First I have to cat the file. The following prints the 19th column awk -F "," '{print $19}' file.txt awk also has length and ifs And I know it all has to be glued together using pipes. I'm just getting stuck at the exact syntax since I have not done much bash programming before.

  • Are frameworks really necessary for beginners/intermediates? (PHP)

    - by ggfan
    I have been programming for around 6months and currently learning PHP/Mysql. I can create basic functionally sites starting from a plain sheet of paper. Is it necessary I use frameworks to create sites? Currently, everything I do is from scratch. I'll borrow codes from old codes, ask people for help, etc. Are frameworks going to help me much more? Is it alright if I put a site public without using a framework? (I have not looked a lot into frameworks, so my knowledge is limited, but I'm just curious)

  • A web application that uses someone else's mail server?

    - by John
    I'm building a web application, call it http://mywebapp.com, where a user should be able to create a newsletter and email it to everyone in his user account's contact list. So he can check mark all his friends, select an html template, fill in the body content, and send. The only catch to this is that after the user sends the email, the recipient must NOT be allowed to trace the source of the email back to http://mywebapp.com. The reason for this condition is because the user is a "reseller" of my business who wants to appear as if he's an independent business. If liability issues arise due to the reseller's unduly usage, I do not want to be caught up in the legal issues. Hence, I do not want anything about my business or technology to be traceable back to me by newsletter recipients. What's the best way to achieve this?

  • How do I create another controller action to create an object in rails?

    - by Angela
    I have a model called Contact_Email. When an Email template is sent through ActionMailer to a specific Contact, as part of the Create action it sends it through upon .save. However, I want to create a "skip" action which also creates a Contact_Email, but does NOT send an ActionMailer and allows me to set the status differently. I want to create a separate action because I want to make this respond to a remote_for_tag so that I can just have an ajax button indicate it has been "skipped": Here's what I tried, but while it creates a Contact_Email, I end up getting an error when I want to go back and view all the Contacts again. def skip @contact_email = ContactEmail.new @contact_email.contact_id = params[:contact_id] @contact_email.email_id = params[:email_id] @contact_email.status = "skipped" if @contact_email.save flash[:notice] = "skipped email" redirect_to contact_emails_url end end

  • I have to generate PL/SQL using Java. Most of the procedures are common. Only a few keeps changing.

    - by blog
    I have to generate PL-SQL code, with some common code(invariable) and a variable code. I don't want to use any external tools. Some ways that I can think: Can I go and maintain the common code in a template and with markers, where my java code will generate code in the markers and generate a new file. Maintain the common code in static constant String and then generate the whole code in StringBuffer and at last write to file. But, I am not at all satisfied with both the ideas. Can you please suggest any better ways of doing this or the use of any design patterns or anything? Thanks in Advance.
