• Will this class cause memory leaks, and does it need a dispose method? (asp.net vb)

• Ruby and RSS2 Feed not displaying image

  - by pcasa

  Trying to create a simple RSS2 Feed that I could later pass on to FeedBurner but can't get RSS feed to display images at all. Also, from what I have read having xml.instruct! on top might cause IE to complain it's not a valid feed. Is this true? My Code looks like xml.instruct! xml.rss "version" => "2.0", "xmlns:dc" => "http://purl.org/dc/elements/1.1/" do xml.channel do xml.title "Store" xml.link url_for :only_path => false, :controller => 'products' xml.description "Store" xml.pubDate @products.first.updated_at.rfc822 if @products.any? @products.each do |product| xml.item do xml.title product.name xml.pubDate (product.updated_at.rfc822) xml.image do xml.url domain_host + product.product_image.url(:small) xml.title "Store" xml.link url_for :only_path => false, :controller => 'products' end xml.link url_for :only_path => false, :controller => 'products', :action => 'show', :id => product.permalink xml.description product.fine_print xml.guid url_for :only_path => false, :controller => 'products', :action => 'show', :id => product.permalink end end end end

• WPF binding to a boolean on a control

  - by Jose

  I'm wondering if someone has a simple succinct solution to binding to a dependency property that needs to be the converse of the property. Here's an example I have a textbox that is disabled based on a property in the datacontext e.g.: <TextBox IsEnabled={Binding CanEdit} Text={Binding MyText}/> The requirement changes and I want to make it ReadOnly instead of disabled, so without changing my ViewModel I could do this: In the UserControl resources: <UserControl.Resources> <m:NotConverter x:Key="NotConverter"/> </UserControl.Resources> And then change the TextBox to: <TextBox IsReadOnly={Binding CanEdit,Converter={StaticResource NotConverter}} Text={Binding MyText}/> Which I personally think is EXTREMELY verbose I would love to be able to just do this(notice the !): <TextBox IsReadOnly={Binding !CanEdit} Text={Binding MyText}/> But alas, that is not an option that I know of. I can think of two options. Create an attached property IsNotReadOnly to FrameworkElement(?) and bind to that property If I change my ViewModel then I could add a property CanEdit and another CannotEdit which I would be kind of embarrassed of because I believe it adds an irrelevant property to a class, which I don't think is a good practice. The main reason for the question is that in my project the above isn't just for one control, so trying to keep my project as DRY as possible and readable I am throwing this out to anyone feeling my pain and has come up with a solution :)

• Managing Many to Many relationships in asp.net Wizard Control

  - by Luis

  Say I have this entity with a lot of attributes. In the input form I have decided to implement a wizard control so I can collect information about this entity in several steps. The problem is that I need to collect information that has been modeled has many to many relationships. I am planning to use a telerik gridview to manage this (add/edit/delete), the problem is where do I store that data since the entity in a insert form is not created on the database yet. OK so I can store all that info in temporary lists residing in the viewstate, waiting for the final submit where I dump all that in the DB, but one of the steps I am collecting files...now storing files in the viewstate is out of the question, same as as storing them in the session... I have been thinking of implementing in a way that the user has to submit some info first (say first 3 steps), commit the data to the database creating the parent entity and then start inserting all the childs entities...but this will get weird as it's confusing since on the first steps you not saving the data to the DB and on the next ones you are commiting directly... Anyone has any thoughts on this? Thanks

• How to know which image is being viewed in UIScrollView? Also, is it possible to loop scrolling for

  - by bruin

  This is what I'm trying to do, and I'm not sure if it's possible using UIScrollView. First, I don't care about zooming, all I care is that the user is able to scroll through images just like the Photo App, this I got. But how do I know which image he is viewing while using UIScrollView? For instance, if he stops on the 3rd image out of 10 images in the view, how do I know he's on that image? I can't find a way to access the index (is this accessible)?? Also, bonus question, once the user scrolls to the last image, I don't want the scrolling to stop but I want it to loop so that image 1 comes after image 10. And vice versa, if you scroll left passed image 1, you'll see image 10. I'm not asking for the logic, I can do this in an array very simply, I just don't know how to access (if it's even possible) the indexing of the images in the scroll view. If it's not, does anyone have a solution to do this? thanks in advance!

• Ideal HTTP cache control headers for different types of resources

  - by chris_l

  I want to find a minimal set of headers, that work with "all" caches and browsers (also when using HTTPS!) On my (GWT-based) web site, I'll have three kinds of resources: 1. Forever cacheable (public / equal for all users) These files don't ever change, and they get a filename based on the MD5 of their contents (this is GWT's approach). They should get cached as much as possible, even when using HTTPS (so I assume, I should set Cache-Control: public, especially for Firefox?) 2. Changing for every new version of the site (public / equal for all users) These files can be cached, but probably need to be revalidated every time. 3. Individual for each request (private / user specific) These resources (e. g. JSON responses) should never be cached unencrypted to disk under no circumstances. (Maybe I'll have a few specific requests that could be cached.) I have a general idea on which headers I would probably use for each type, but there's always something I could be missing.

• Rails: Obfuscating Image URLs on Amazon S3? (security concern)

  - by neezer

  To make a long explanation short, suffice it to say that my Rails app allows users to upload images to the app that they will want to keep in the app (meaning, no hotlinking). So I'm trying to come up with a way to obfuscate the image URLs so that the address of the image depends on whether or not that user is logged in to the site, so if anyone tried hotlinking to the image, they would get a 401 access denied error. I was thinking that if I could route the request through a controller, I could re-use a lot of the authorization I've already built into my app, but I'm stuck there. What I'd like is for my images to be accessible through a URL to one of my controllers, like: http://railsapp.com/images/obfuscated?member_id=1234&pic_id=7890 If the user where to right-click on the image displayed on the website and select "Copy Address", then past it in, it would be the SAME url (as in, wouldn't betray where the image is actually hosted). The actual image would be living on a URL like this: http://s3.amazonaws.com/s3username/assets/member_id/pic_id.extension Is this possible to accomplish? Perhaps using Rails' render method? Or something else? I know it's possible for PHP to return the correct headers to make the browser think it's an image, but I don't know how to do this in Rails... UPDATE: I want all users of the app to be able to view the images if and ONLY if they are currently logged on to the site. If the user does not have a currently active session on the site, accessing the images directly should yield a generic image, or an error message.

• A Better way? Finding ASP.NET controls, finding their id

• Binding between Usercontrol with listbox and parent control (MVVM)

My question is - WHY?

• Is there a more elegant solution than an if-statement with no else clause?

  - by Jay

  In the following code, if Control (the element that trigers Toggle's first OL) is not Visible it should be set Visible and all other Controls (Controls[i]) so be Hidden. .js function Toggle(Control){ var Controls=document.getElementsByTagName("ol",document.getElementById("Quote_App")); var Control=Control.getElementsByTagName("ol")[0]; if(Control.style.visibility!="visible"){ for(var i=0;i<Controls.length;i++){ if(Controls[i]!=Control){ Reveal("hide",20,0.3,Controls[i]); }else{ Reveal("show",20,0.3,Control); }; }; }else{ Reveal("hide",20,0.3,Control); }; }; Although the function [Toggle] works fine, it is actually setting Controls[i] to Hidden even if it is already. This is easily rectified by adding an If statement as in the code below, surely there is a more elegant solution, maybe a complex If condition? .js function Toggle(Control){ var Controls=document.getElementsByTagName("ol",document.getElementById("Quote_App")); var Control=Control.getElementsByTagName("ol")[0]; if(Control.style.visibility!="visible"){ for(var i=0;i<Controls.length;i++){ if(Controls[i]!=Control){ if(Controls[i].style.visibility=="visible"){ Reveal("hide",20,0.3,Controls[i]); }; }else{ Reveal("show",20,0.3,Control); }; }; }else{ Reveal("hide",20,0.3,Control); }; }; Your help is appreciated always.

• Android - Memory leak when dynamically building UI with image resource backgrounds

  - by Rich

  I have an Activity that I swear is leaking memory. The app I'm working on does a lot with images, so I've had to be pretty stingy with memory when working directly with Bitmaps. I added an Activity, and now if you use this new Activity it basically puts me over the edge with mem usage and I end up throwing the "Bitmap exceeds VM budget" exception. If you never launch this Activity, everything is smooth as it was previously. I started reading about memory leaks, and I think that I have a similar situation to what is described in the article in the Android docs. I'm dynamically creating a bunch of image views and adding a BackgroundDrawable from the resources and adding an OnClickListener as well. I imagine I have to do some cleanup when the Activity hits onPause in its life cycle, but I'd like to know specifically what is the correct way. Here is the code that should demonstrate the objects I'm working with... LinearLayout templateContainer; . . . ImageView imgTemplatePreview = (ImageView) item.findViewById(R.id.imgTemplatePreview); . . . imgTemplatePreview.setBackgroundDrawable(getResources().getDrawable(previewId)); imgTemplatePreview.setOnClickListener(imgClick); templateContainer.addView(item);

The form is a simple info box which pops up, and clicking anywhere on it does the same thing (sort of like Outlook's email notifier.) To do this, I've written a recursive method to add a MouseClick handler to each control, as follows: private void AddMouseClickHandler(Control control, MouseEventHandler handler) { control.MouseClick += handler; foreach (Control subControl in control.Controls) AddMouseClickHandler(subControl, handler); } However, if I wanted to add a handler for all of the MouseDown and MouseUp events, I'd have to write two more methods. I'm sure there's a way around this, but I can't find it. I want a method like: private void AddRecursiveHandler(Control control, Event event, EventHandler handler) { control.event += handler; foreach (Control subControl in control.Controls) AddRecursiveHandler(subControl, event, handler); }

• DrawImage in XP Mode or Remote Desktop

  - by simplecoder

  I'm displaying a PNG with a transparent background that looks good in Windows 7, but then I run my app in XP Mode or remote desktop to a Windows XP machine and the PNG looks incorrect. I noticed that if I disable "Integration Mode" or run the app on XP without remote desktop, the image looks fine. How do I get DrawImage to render the PNG correctly in XP Mode or remote desktop? Image inside Windows 7 Image inside XP Mode or remote desktop Here's my code: protected override void OnPaint(PaintEventArgs e) { Image image = Image.FromFile("hello.png", false); Bitmap bmp = new Bitmap(image); Rectangle destRect = new Rectangle(0, 0, image.Width, image.Height); e.Graphics.DrawImage(image, destRect, 0, 0, image.Width, image.Height, GraphicsUnit.Pixel); base.OnPaint(e); }

• Custom Image Button and Radio/Toggle Button from Common Base Class

  - by Wonko the Sane

  Hi All, I would like to create a set of custom controls that are basically image buttons (it's a little more complex than that, but that's the underlying effect I'm going for) that I've seen a few different examples for. However, I would like to further extend that to also allow radio/toggle buttons. What I'd like to do is have a common abstract class called ImageButtonBase that has default implementations for ImageSource and Text, etc. That makes a regular ImageButton implementation pretty easy. The issue I am having is creating the RadioButton flavor of it. As I see it, there are at least three options: It would be easy to create something that derives from RadioButton, but then I can't use the abstract class I've created. I could change the abstract class to an interface, but then I lose the abstract implementations, and will in fact have duplication of code. I could derive from my abstract class, and re-implement the RadioButton-type properties and events (IsChecked, GroupName, etc.), but that certainly doesn't seem like a great idea. Note: I have seen http://stackoverflow.com/questions/2362641/how-to-get-a-group-of-toggle-buttons-to-act-like-radio-buttons-in-wpf, but what I want to do is a little more complex. I'm just wondering if anybody has an example of an implementation, or something that might be adapted to this kind of scenario. I can see pros and cons of each of the ideas above, but each comes with potential pitfalls. Thanks, wTs

• How to control access to third party HTML pages

  - by Wylie

  Hello, We have a Learning Management System (LMS) that runs on its own server (IIS/Server 2003). Students must login with Forms authentication to gain access to the content. We want to offer access to third party flash and audio that is embedded in HTML pages hosted on the third party server (IIS/Server 2003). Currently we use a frame in a pop-up window that is populated via a simple URL to the third party HTML pages. How can the third party control access to their content, so that only students who launch the pop-up windows from our site can access their content? Since the content is mostly video and flash, we would prefer not to stream all of their content through our server to the Student. We have a programming staff, so we could maybe... - either post or get for our HTTP request to the third party server - we could use SSL - we could programmatically assign a global NT user account to all of our users and then do some kind of Active Directory login from the LMS server to the third party server - could the third party content be hosted at Amazon S3? Would this allow for secure access/download? These are just ideas. We really have no idea. Any suggestions would be greatly appreciated. TIA, Wylie
