• ASP.NET - Themes and Relative Referencing

  - by user70192

  Hello, I have an ASP.NET application that uses themes. Let's pretend I have a theme named "MySkin". I have a page that is in a sub-directory of my application. When I reference a page that uses "MySkin", I noticed that ASP.NET renders a link element that walks up to the root of the site and then down into the App_Themes directory. Here is an example link element I found in a rendered ASP.NET page: <link href="../../App_Themes/MySkin/theme.css" type="text/css" rel="stylesheet" /> Is there a reason that the rendered link element does not use the following instead: <link href="/App_Themes/MySkin/theme.css" type="text/css" rel="stylesheet" /> Is this a browser compatibility issue or is there another reason? The reason I am asking is because I am rendering my ASP.NET page using Server.Execute and storing the result in a different directory. Because of this, I would prefer to use the second way to reference my theme's css. Thank you!

• F5 irule with RESTful services

  - by Kyle Hayes

  I'm trying to come up with a rule on our F5 to direct traffic to our Tomcat server appropriately. We are deploying separate WAR files for each RESTful service. So, we would like to have the following URIs as an example: /services/quiz/01234/ /services/user/54321/ Where 'quiz' and 'user' are quiz.war and user.war respectively. We want to direct the traffic at the F5 level for /services/ to be the root and the rest of the URI to be directed to the Tomcat server. How do we accomplish this? Edit The browser url for a resource would look like http://www.domain.com/services/quiz/01234/ I want BIG-IP to send the request to tomcat as http://tomcatserver:8080/quiz/01234/ so basically remove /services and append everything after it to the tomcat domain. I would think this would be an easy regex, right?

• What's the usual term for a local IIS/web application with services?

  - by JBRWilkinson

  I've inherited a multi-technology project which comprises a Flash user interface contained in a web-browser-like host and has an ASP.NET piece which provides web services to the Flash UI, background/watchdog services plus a web application for administration of the system. Our transatlantic project conference calls are getting confusing due to the various terms people use to describe the ASP.NET piece. Indeed, ASP.NET has its' own project terminology including 'Web Site' and 'Web Application' to both of which one can add a 'Web Service'. Is there any commonly-used name for this ASP.NET multi-purpose project piece?

• crunching multiple js files during development

  - by Yaron Naveh

  I'm writing a backbone.js app. I have multiple js, css and html template files. I also have a script to crunch them into a single file so it is faster to download. How should I work during development: Add a listener to the file system and after every change compile the files so I can see it in a browser. This implies a 1-2 seconds overhead before I can see what I did, which is annoying for html fine-tuning. Somehow browse using the multiple files during development and only crunch before going to production. This means I need to have a separate index.html for dev and prod. What's your take?

• Python: Is there a way to get HTML that was dynamically created by Javascript?

  - by Joschua

  As far as I can tell, this is the case for LyricWikia. The lyrics (example) can be accessed from the browser, but can't be found in the source code (can be opened with CTRL + U in most browsers) or reading the contents of the site with Python: from urllib.request import urlopen URL = 'http://lyrics.wikia.com/Billy_Joel:Piano_Man' r = urlopen(URL).read().decode('utf-8') And the test: >>> 'Now John at the bar is a friend of mine' in r False >>> 'John' in r False But when you select and look at the source code of the box in which the lyrics are displayed, you can see that there is: <div class="lyricbox">[...]</div> Is there a way to get the contents of that div-element with Python?

• Tortoise SVN revision history

  - by rahul

  I want to know for how long the tortoise svn keeps the revision history. Say I have a file which I deleted from repository through repo browser an year ago, will I be able to still recover that file? If I am able to recover, I also want to know the method to permanently delete that earlier copy of file and related revisions history so that in future nobody is able to access that file. Is it possible? I have run into problems in my organisation as I did frequent updations and deletions assuming that file was getting deleted permanently. The file system of repository has bloated now. Please suggest how to fix it.

• Holy grail layout with 100% height

  - by Henrik Skogmo

  I am trying to make a css layout that looks like this http://oi53.tinypic.com/o0v0vp.jpg The CSS term for this type of layout is known as the "holy grail" I think. The problem I am facing is that when I use layouts and solutions I find online I do not get them to work properly as I want them to. What I am trying to do is make a page that, regardless of content, will have the footer at the bottom of the browser and the columns stretching down to it. So far I have only seen pages that have the footer placed where the content stop, the result is some blank space under the footer. If anyone could help me out on this it would be greatly appreciated!

• How does Twitter for iPhone bookmarklet work?

  - by Igor Zevaka

  Twitter client (formerly Tweetie) allows you to define a bookmarklet in Safari that launches the app. I want to know which iPhone API allows you to register the protocol specifier (or whatever it's called) - in this case "tweetie:" - in order for this bookmarklet to work. The instructions can be found here and the bookmarklet itself is below. javascript:window.location='tweetie:'+window.location Clicking the above bookmark is the same as typing in "tweetie:http://google.com" into the address bar. This is obviously supported on the OS/Browser level, much the same as tel: URIs. Am I correct in understanding that developers can add arbitrary URI protocol specifiers as a part of app installation?

• Manually Writing the HTML in TWebBrowser

  - by nomad311

  I am using the strategy suggested here: http://cc.embarcadero.com/Item/23992 to get my HTML in the TWebBrowser, but I get a bunch of JavaScript errors when the page loads. If I click yes enough times I can see a page with no formatting and I'm guessing the page does nothing. My theory is that because the links in the HTML are relative, the browser can't load any of it. I have switch from passing the URL, 'about:blank' to the navigate function, to passing the servers home page - in the hopes that some internal mechanism will be able to generate full paths, but no luck. Any one successfully been able to manually write HTML to the TWebBrowser.

• Silverlight data-driven application with NHibernate

  - by Tigraine

  Hi Guys, this is more of a subjective Question, but I'll ask it anyway. I'm about to develop a very data-centric application that has to run inside the browser. The frontend will be Silverlight, backed by a Fluent NHibernate service that runs server side. The problem here is: Wherever I look for data-driven silverlight app I wind up finding Silverlight RIA services examples, but nothing on how to build this without some ADO.NET stuff involved. I have little to no knowledge in WCF so far, but from the limited research I did it seems like WCF is pretty much the only way to let the client talk to the server. Are there any tutorials/best practices on how to write a Silverlight MVVM app that provides CRUD for a non-EF database? Suggestions would be very much appreciated. Thanks PS: I can't use .NET remoting. The backend has to run on IIS6 :(

• PHP upload file using PUT instead of POST

  - by Marco Demaio

  I read something about this on PHP docs, but it's not celar to me: Do the most widely used browsers (IE, FF, Chrome, Safari, Opera, ...) support this PUT method to uplaod files? What HTML should I write to make the browser call the server via PUT request. I mean do I need to write a FORM with an INPUT file field and just replace the attribute method="POST" with the method="PUT"? On the PHP docs (link above) they say a PUT request is much simplier than a POST request when uploading file, along with this advantage, what other advantages/disadvanatges do the PUT has comapred to teh POST? Thanks!

• Dynamically append number to PDF or make submit button change its URL based on that number.

  - by jamone

  I'm serving up PDFs from a SQL db and presenting them in the browser. I'm trying to figure out a way to embed a number in the PDF dynamically that is the recordID for that PDFs SQL record so that when the user hits the submit button and the form submits its XML data to my submission page I can tell which PDF this is. If there is some way of changing the submission URL on the fly then I could do a query string to pass my self the recordID. I'm not generating the PDF in code, its being created by hand and then uploaded to my site.

• How to upload binary (audio) data from a Flash AS3 client to .NET server (WCF/REST/HTTP/?)?

  - by Bobby

  Simply stated: I'm trying to record audio in a browser, and get that data back up to the server. I originally tried to capture, encode and upload the audio using Silverlight, but because of the lack of suitable client-side encoding options, I'm now giving Flash a shot (Flash has baked-in support for encoding to Speex). I think I've figured out how to capture and encode the audio... But now what was easy in Silverlight, is the challenge in Flash. My server-side is .NET: MVC2- I'm open to receiving the audio in whatever manner is best- REST, WCF.. So that's my question: How could one upload binary data from Flash, to a .NET server-side endpoint. If the answer is WCF: then how would one setup the client-side proxies to communicate with the service? If the answer is REST or HTTP Post, then how would one construct this HTTP request and pass along the data? I've been reading up on AS3, but am new to Flash dev... Thanks for any help!

• Converting MS Word Documents to PDF in ASP.NET

  - by glaxaco

  Similar questions have been asked, but nothing exactly like mine, so here goes. We have a collection of Microsoft Word documents on an ASP.NET web server with merge fields whose values are filled in as a result of user form submissions. After the field merge, the server must convert the document to PDF and stream it down to the browser. Our first inclination was to use the Visual Studio Tools for Office API; however, we ran into this warning from Microsoft: Microsoft does not currently recommend, and does not support, Automation of Microsoft Office applications from any unattended, non-interactive client application or component (including ASP, ASP.NET, DCOM, and NT Services), because Office may exhibit unstable behavior and/or deadlock when Office is run in this environment. It looks like the field manipulation can be done using the Open XML SDK, but what's the best way to convert Word 2007 documents to PDF without opening Word? The optimal solution would be low-cost, scalable, have a low memory footprint, be easy to deploy, and have a .NET API.

• Select elements based on class and element type

  - by Beau Martínez

  How can I select all elements within an HTML document with a specific class and specific element type? I'm trying to select all anchors with the class title loggedin from an HTML document (and then open them within the browser). These are within parragraphs with the class title. They are leafs in the following DOM tree: + body + div class='content' + div id='siteTable' class='sitetable linklisting' + div class='thing id-t3_xxxx xxx xxx link' + div class='entry unvoted' + p class='title' + a class='title loggedin ' Where x indicates variable content. (I'm looking to do this in raw JavaScript, ie, not in jQuery.)

• Is it possible to take a screenshot of a web page with Javascript or HTML5/Canvas?

  - by Ryan Kearney

  Is there a way I could insert some code into a page that would take a screenshot of what the user sees in the browser window, then upload that image via a web form of some sort? I'm working on a clone of a pay-to-use service that lets you install a widget on a web page which in turn allows viewers to report bugs in the sites layout. Currently they use a Java applet to take the screenshot, which, in my opinion, is probably the worst way to go about it (aside from requiring the user to install a plugin) Is there a javascript/flash/other alternative? Thanks

• How can a hacker put a file on my server root (apache, php, 1and1)

  - by mike-sav

  Hi there, I have a site hosted on 1and1 and a couple of weeks ago I noticed a hacker had put a .php file on the server that when viewed in a browser exposed my DB schema, DB connection strings, FTP account (for file uploads using a form), etc, etc. Naturally I panicked and I wiped the server and reuploaded my files. Fortunatley I encrypt passwords using MD5 and I don't store things like credit card details, etc, etc. Now I checked my files and with all user input I use a clean function (htmlentities, sql_real_escape_string, etc, etc) that strips the input of any XSS or SQL injection. I have also made sure that the session key gets re-engineered when a user status changes (like they log into their account) to prevent session hijacking, my folder permissions are set to 755 and file permission are 644. Has anyone got any idea how this could have happened? Or if I'm missing something

• Web design process with CSS - during or after?

  - by SyaZ

  Which is the better practice? Add CSS during web designing you can see the result (or close) as early as possible and make required changes. You also know how many divs or spans you might need (eg to make curved cross-browser hover background). But as you add more and more components to the page sometimes things get hack-ish as you need to patch here and there to get the exact design required. Add CSS after finishing page design you can see the page overall structure as it is well, without styles. You get to see how accessible your site is, and modify it right away if it's not good enough (unlike the former case where you may break multiple CSS rules). Plus after you finished it, you only need to spend most of the time to alter only the CSS file, which is good to get the momentum going. Granted I have never tried the latter approach, but am seriously considering it for my next project if I can see convincing reasons -- or if it's no good at all. Thanks.

• IE6 image scaling with bicubic filter

  - by thehuby

  I have a project where I have to resize some images in the actual browser side. IE8, FF3 et al all apply a filter to smooth the resizing of the image, so in these browsers everything looks good. In IE7 I have applied the following fix which works great: -ms-interpolation-mode:bicubic; In IE6 however I can only find references to the AlphaImage Filter (the same one used to enable alpha transparency on PNG files). However I can't find an example of how to use it, nor have I been able to get it working myself. Can anyone provide me with an example? Preferably applied to actual img tags, though I could use background images if required. MSDN link (for what its worth): http://msdn.microsoft.com/en-us/library/ms532969%28VS.85%29.aspx The code I am using in my CSS is applied to the img, though I've tried applying it to the img container as well (with no effect): #provider-list li img { filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src="/image.gif", sizingMethod="scale"); } A thousand thank you's in advance :) Rick

• Is it valid to have more than one question mark in a URL?

  - by Bungle

  I came across the following URL today: http://www.sfgate.com/cgi-bin/blogs/inmarin/detail??blogid=122&entry_id=64497 Notice the doubled question mark at the beginning of the query string: ??blogid=122&entry_id=64497 My browser didn't seem to have any trouble with it, and running a quick bookmarklet: javascript:alert(document.location.search); just gave me the query string shown above. Is this a valid URL? The reason I'm being so pedantic (assuming that I am) is because I need to parse URLs like this for query parameters, and supporting doubled question marks would require some changes to my code. Obviously if they're in the wild, I'll need to support them; I'm mainly curious if it's my fault for not adhering to URL standards exactly, or if it's in fact a non-standard URL.

• Custom http service responds fine to local IP address but NOT to localhost or 127.0.0.1

  - by Scrappydog

  I'm trying to connect to a custom http service written by another developer. The service responds fine on a local IP address and port number. Such as: http://10.1.1.1:1234 but it does NOT respond to http://localhost:1234 or http://127.0.0.1:1234 The service is a simple single function application written in VC++ that takes an http post string and returns another string. I'm trying to all it from C# using HttpWebRequest.GetResponse, but I can reproduce the same problem manually from a web browser... Test environment is Windows 2008 Server. Bottom line I'm looking for some troubleshooting tips to help the other developer fix his code.

• Google App Engine : PolyModel + SelfReferenceProperty

  - by rvandervort

  Is a PolyModel-based class able to be used as a SelfReferenceProperty ? I have the below code : class BaseClass(polymodel.PolyModel): attribute1 = db.IntegerProperty() attribute2 = db.StringProperty() class ParentClass(BaseClass): attribute3 = db.StringProperty() class ChildClass(BaseClass): parent = SelfReferenceProperty(collection_name = 'children') p = ParentClass() p.attribute1 = 1 p.attribute2 = "Parent Description" p.attribute3 = "Parent additional data" p.put() c = ChildClass() c.attribute1 = 5 c.attribute2 = "Child Description" c.parent = p.key() c.put() I execute this code and check the datastore via the development server's admin interface. The parent instance is saved to the datastore class = 'BaseClass,ParentClass', but the child is not. There is no error output to the browser (debug is turned on) and nothing in the launcher's log for my app. Is this possible to do ?
