  • Is it possible that __doPostBack() would ever send a GET request?

    - by Galilyou
    I'm having a problem with telerik RadGrid, I want to enable multiple row selection. I also want to go to the server whenever a row is selected or deselected. I created a javascript function to handle the Grid's client side events (OnRowSelected, and OnRowDeSelected). The functions look like this: function onOperationRowSelected(sender, eventArgs) { __doPostBack("<%=myControl.ClientID %>", "rowSelected:" + eventArgs.get_itemIndexHierarchical()); } The other function is very similar, the only difference is that it sends the string "rowDeselcted" instead of "rowSelected". On Page_Load I check to see if the request is a Post request using "IsPostBack" and if so, I check to see if it's a rowSelected or rowdeselected. My problem is when I select a first raw on my grid, a Post request happens (which is expected), however, when I select the second row, a GET request is issued, which (obviously) will result in IsPostBack returning false. What am I missing here?

  • Super Cam iphone app how do they make it possible?

    - by Silent
    there is an iphone app called supercam and you can get it through the app store free. This app features a way to connect your webcam or dv cam that is connected on the internet, you could set up the ip address and enter the data on the app and it will connect to your online camera. the thing is that they have the video stream and it looks like they embedded the video in a uiview or webview at the bottom they have buttons to choose from all the cameras you have set up. so this is different from other video streaming apps because it does not play the video from the full screen mode (MPMediaPlayer API) would there be any tutorials about this or somehow take reverse engineer this?

  • Is it possible to rebind sql paramters using the result from a cfquery?

  • Is it actually possible to connect to ActiveMQ via XMPP and query/browse queues using "AciveMQ.Agen

    - by Oleg Kiorsak
    I tried what I think are 4 most popular XMPP (aka "Jabber") clients (Spark, Pidgin, Psi, Pandion) to connect to ActiveMQ instance (Apache ActiveMQ ver. 5.3.0) on XMMP connector with an idea to use the "AciveMQ.Agent chatroom" for querying queues/etc and no success at all Some of them fail with 'Unknown error', some don't fail but kind of "hang"... interestingly, some communication does indeed reach the ActiveMQ side, because when I close a client it spits an exception "could not close" or something to that effect... and if I try "register new user" option (present on most clients" the ActiveMQ also spits some most cryptic warning message But I was never able to get to the point when I could see or specify "ActiveMQ.Agent" as chatroom and issue any commands... Before I waste any more time on this curious feature, I would like to hear whether anyone had any success with it? Thank you! PS: BTW, the book "ActiveMQ in Action book" http://www.manning.com/snyder/ shows that it is apparently works and is very easy using some Mac client (AdiumX), but I wanted it on a Windows PC ;)

  • Is Accessing USB from web application for cross browser cross os possible at all ?

    - by Ved
    Hey Guys, I am wondering if there is anyway we can achieve this. I heard different things about Silverlight 4 , Java Script or Active X control but not seen any demo of code for any of them. Does anyone know any web component that is available or how to write one. We really like capture client's USB drive via Web and read/write data on it. This has to work for ANY Operating system in Any web browser. Thanks UPDATED What about WPF in browser mode...I read that I can host my wpf apps inside browser and sort of like smart client. Here is a great example of doing this via silverlight 4 but author mentions about possibility of accessing USB on MAC via 1) Enable executing AppleScripts. This option will let us have the same amount of control on a mac machine as we do on a windows machine. 2) Add an overload to ComAutomationFactory.CreateObject() that calls the “Tell Application” command under the scenes and gets a AppleScript object. This option would work extremely well for Office automation. For any other operating system feature, you’ll have to code OS access twice.  I did not quite understand it. Has any tried this ?

  • Collection wrapping a array is read-only. Possible to make it writeable without casting?

    - by Brian Triplett
    I have a Collection<T> property that wraps a array like T[] array; public Collection<T> Items { get { return new Collection<T>(array); } } When I attempt to assign to the collection via: T variable; Items[i] = variable; I get a NotSupportedException because the colleciton's IsReadOnly property is true. Turns out that this is a design choice by Microsoft. Does anyone know a workaround that does NOT involve enumeration? It could be done if the underlying data is not an array but I enjoy the performance gains because the data is fixed length.

  • Is it possible to use DLR in a .NET 3.5 website project?

    - by Aplato
    I'm trying to evaluate an expression stored in a database i.e. "if (Q1 ==2) {result = 3.1;} elseif (Q1 ==3){result=4.1;} else result = 5.9;" Rather than parsing it myself I'm trying to use the DLR. I'm using version .92 from the Codeplex repository and my solution is a .NET 3.5 website; and I'm having conflicts between the System.Core and Microsoft.Scripting.ExtenstionAttribute .dll's. Error = { Description: "'ExtensionAttribute' is ambiguous in the namespace 'System.Runtime.CompilerServices'.", File: "InternalXmlHelper.vb" } At this time I cannot upgrade to .NET 4.0 and make significant use of the .net 3.5 features (so downgrading is not an option). Any help greatly appreciated.

  • Is it possible to filter users from a launchd plist?

    - by compriots
    I have some launchd plists that are now placed at the administrator per-user level, particularly inside: - /Library/LaunchAgents OR - /Library/LaunchDaemons I'd like to avoid that some of those services could start only for one user (possibly avoiding to move all the plists to ~/Library/LaunchAgents), which is the simplest way? Thanks in advance.

  • Is it possible to share session state between asp.net aspx page making a call to an asp.net webservi

    - by Greg Balajewicz
    My Situation: I have 1 asp.net application with both aspx pages AND webservices I make calls (using ajax) to the webservice from an aspx page - all within the same asp.net application! Here is my problem/question Is there any way to share the session state? I.e. - the aspx page has a sessionID and the state is being maintained. When the call to the webservice is made, is there a way to automatically send the seesionID to the webservice and then be able to access the same session state from the webservice? -- That would greatly simplify my work! :) Many thanks for your ideas!!

  • MovableType: Is it possible to have a rss feed for "todays" entries?

    - by tomwolber
    Background Our email vendor supports rss feeds for dynamic content, which we use successfully for "daily headline" type emails. This is a great help in automating many different emails that we don't have staffing to create daily. One of our staff as requested that his daily email (which has recent headlines from his Movable Type blog) only have headlines from entries posted on that day. My Question Since we use Movable Type for his blog, is there a way to generate a rss feed that only contains items posted on the current day?

  • Is it possible to combine these 3 mySQL queries?

    - by Greenie
    I know the $downloadfile - and I want the $user_id. By trial and error I found that this does what I want. But it's 3 separate queries and 3 while loops. I have a feeling there is a better way. And yes, I only have a very little idea about what I'm doing :) $result = pod_query("SELECT ID FROM wp_posts WHERE guid LIKE '%/$downloadfile'"); while ($row = mysql_fetch_assoc($result)) { $attachment = $row['ID']; } $result = pod_query("SELECT pod_id FROM wp_pods_rel WHERE tbl_row_id = '$attachment'"); while ($row = mysql_fetch_assoc($result)) { $pod_id = $row['pod_id']; } $result = pod_query("SELECT tbl_row_id FROM wp_pods_rel WHERE tbl_row_id = '$pod_id' AND field_id = '28'"); while ($row = mysql_fetch_assoc($result)) { $user_id = $row['pod_id']; }

  • 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

  • Is it possible to parse a stylesheet with Nokogiri?

    - by wbharding
    I've spent my requisite two hours Googling this, and I can not find any good answers, so let's see if humans can beat Google computers. I want to parse a stylesheet in Ruby so that I can apply those styles to elements in my document (to make the styles inlined). So, I want to take something like <style> .mystyle { color:white; } </style> And be able to extract it into a Nokogiri object of some sort. The Nokogiri class "CSS::Parser" (http://nokogiri.rubyforge.org/nokogiri/Nokogiri/CSS/Parser.html) certainly has a promising name, but I can't find any documentation on what it is or how it works, so I have no idea if it can do what I'm after here. My end goal is to be able to write code something like: a_web_page = Nokogiri::HTML(html_page_as_string) parsed_styles = Nokogiri::CSS.parse(html_page_as_string) parsed_styles.each do |style| existing_inlined_style = a_web_page.css(style.declaration) || '' a_web_page.css(style.declaration)['css'] = existing_inlined_style + style.definition end Which would extract styles from a stylesheet and add them all as inlined styles to my document.

  • CSS: Possible to define styles mid way through an html document?

    - by Dr. Zim
    In ASP.NET MVC, there are these snippets of html called view templates which appear when their matching data appears on the screen. For example, if you have a customer order and it has a vendor address, the vendor address view template shows up populated with data. Unfortunately, these don't have access to "MasterPages" nor are aware of their CSS surroundings. Instead of loading these up with style tags, is there any way to create partial CSS files that could work for that particular html snippet, a sort of in-line CSS style section? It would be really nice to plop this down just before we render the partial view: <style type="text/css"> input { margin: .2em .2em; overflow: hidden; width: 18.8em; height: 1.6em; border: 1px solid black;} </style> to have the 15 or so input fields in that particular Html snippet be formatted the same. These are swapped out, so the positions of the input fields change. This may also imply a CSS reset on each partial view.

  • Is it possible to return a SiteMap as a JsonResult?

    - by Paul Suart
    I've got a very simple Action on my Controller that's attempting to return my XmlSiteMap as a JsonResult: public ActionResult Index() { var nodes = SiteMap.Provider.RootNode; return new JsonResult() { Data = nodes, JsonRequestBehavior = JsonRequestBehavior.AllowGet }; } However, when I call the Action, an InvalidOperationException is thrown: "A circular reference was detected while serializing an object of type 'System.Web.SiteMapNode'." Is there a way to Json serialize a SiteMap, or indeed any object that has children of the same type?

  • Is it possible to change WCF service without regenerating & recompiling client proxy?

    - by Buu Nguyen
    Let's say I have a WCF service which has a method returning object Person. In one of the clients of this service, I can add service reference to the service and start using its method. Now, let's say the Person class is changed on the server, having a new DataMember added. Other clients will make use of this new DataMember, but my client doesn't. Therefore, this client shouldn't even be aware that the service returns s/t "more" than what it needs. Is there any way that my client can still work with the service without having to update the service reference (which, as I understand, means regenerating the proxy & compiling it)?
