  • ASP.Net MVC Keeping action parameters between postbacks

    - by Matt
    Say I have a page that display search results. I search for stackoverflow and it returns 5000 results, 10 per page. Now I find myself doing this when building links on that page: <%=Html.ActionLink("Page 1", "Search", new { query=ViewData["query"], page etc..%> <%=Html.ActionLink("Page 2", "Search", new { query=ViewData["query"], page etc..%> <%=Html.ActionLink("Page 3", "Search", new { query=ViewData["query"], page etc..%> <%=Html.ActionLink("Next", "Search", new { query=ViewData["query"], page etc..%> I dont like this, I have to build my links with careful consideration to what was posted previously etc.. What I'd like to do is <%=Html.BuildActionLinkUsingCurrentActionPostData ("Next", "Search", new { Page = 1}); where the anonymous dictionary overrides anything currently set by previous action. Essentially I care about what the previous action parameters were, because I want to reuse, it sounds simple, but start adding sort and loads of advance search options and it starts getting messy. Im probably missing something obvious

    Say I have my custom taglib: <%@ taglib uri="http://foo.bar/mytaglib" prefix="mytaglib"%> <%@ taglib uri="http://java.sun.com/jstl/core" prefix="c"%> <mytaglib:doSomething> Test </mytaglib:doSomething> Inside the taglib class I need to process a template and tell the JSP to re-evaluate its output, so for example if I have this: public class MyTaglib extends SimpleTagSupport { @Override public void doTag() throws JspException, IOException { getJspContext().getOut().println("<c:out value=\"My enclosed tag\"/>"); getJspBody().invoke(null); } } The output I have is: <c:out value="My enclosed tag"/> Test When I actually need to output this: My enclosed tag Test Is this feasible? How? Thanks.

  • Configure Tomcat to send web pages compatible to IE 7 or 6

    - by Spiderman
    I have got an application that is not compatible to work using IE8 browser. I am looking for a way to to configure Tomcat on which this application run, so the pages could be read by IE8 and treated as if they are IE7 or IE6 By googling so far I found a possible suggestion which say to add to the http response the header: X-UA-Compatible: IE=EmulateIE7 here that tell IE8 to be like IE7. The problem is that this way requires adding a filter that should be added on application level. I'd like to know if any of you is familiar with a more generic way that Tomcat enables to send its http content to be IE7 (or IE6) compatible ?

  • Show a window from 32-bit NPAPI Plugin in 64-bit Safari

    - by Glenn Howes
    I have an old NPAPI plugin for OS X that I'm trying to refit for use with Snow Leopard's version of Safari. My problem is that when I switch Safari to 64-bit mode, it changes the plugin environment to out of process mode (where plugins are hosted by a 32-bit WebKitPluginHost process). And now my toolbar palettes are not visible on screen, even though the NSPanels on which they are based think they are visible. The documentation says that bringing up windows is not recommended, but doesn't say its prohibited; is there something I can do to bring up my Windows?

  • Start Android intent from email

    - by AndersWid
    Hi! I need a good way of sending information TO the Android device that doesn't use a special server that has XML data. I would like to base this around email functionality. Lets say I send an email with some special text/link that when clicked starts and intent on the phone. I don't want to replace the users current email application. A clickable link would be the best thing "intent://data1:data2" or something along these lines. Speculations/solutions on how to proceed.

  • Converting UTF-8 to ISO-8859-1 in Java - how to keep it as single byte

    - by luckylak
    Hi, I am trying to convert a string encoded in java in UTF-8 to ISO-8859-1. Say for example, in the string 'âabcd' 'â' is represented in ISO-8859-1 as E2. In UTF-8 it is represented as two bytes. C3 A2 I believe. When I do a getbytes(encoding) and then create a new string with the bytes in ISO-8859-1 encoding, I get a two different chars. â. Is there any other way to do this so as to keep the character the same i.e. âabcd?

  • LD_LIBRARY_PATH : how to find a shared object

    - by CuriousDawg
    I have a shared object ( libxyz.so ). Given LD_LIBRARY_PATH, how can find the exact location of this shared object? If i had a binary that depends on this lib, i would have used ldd on that. Here is the reason why i ask: I have a cgi script which works when using LD_LIBRARY_PATH set to say VALUE1. It does not work when the path is set to VALUE2. I would like to find the exact location of the library as specified by the path in VALUE1 ( Note that VALUE1 has almost 20+ different locations ) Platform: Linux

  • performance of linq extension method ElementAt

    - by Fabiano
    Hi The MSDN library entry to Enumerable.ElementAt(TSource) Method says "If the type of source implements IList, that implementation is used to obtain the element at the specified index. Otherwise, this method obtains the specified element." Let's say we have following example: ICollection<int> col = new List<int>() { /* fill with items */ }; IList<int> list = new List<int>() { /* fill with items */ }; col.ElementAt(10000000); list.ElementAt(10000000); Is there any difference in execution? or does ElementAt recognize that col also implements IList< although it's only declared as ICollection<? Thanks

  • Getting values from Multiple Text Entry using Pygtk and Python

    - by Webrsk
    On a click of a button named "Add Textbox" it calls a function which creates a single textbox using (gtk.Entry) function. So each time i click that button it creates a textbox. I have a submit button which should fetches all the values of the text boxes(say 10 textboxes) generated with the name of "entry". It works for one textbox but not for multiple. In php we can create dynamix textboxes mentioning as an array name=entry[]. Do we have similar functionality in python ? Enviroment : FC10 , Glade 3 , Python 2.5 , GTK.

  • Aaron Hillegass Chapter 18 Challenge Question

    - by jasonbogd
    I am working through Aaron Hillegass' Cocoa Programming for Mac OS X and am doing the challenge for Chapter 18. Basically, the challenge is to write an app that can draw ovals using your mouse, and then additionally, add saving/loading and undo support. I'm trying to think of a good class design for this app that follows MVC. Here's what I had in mind: Have a NSView-subclass that represents an oval (say JBOval) that I can use to easily draw an oval. Have a main view (JBDrawingView) that holds JBOvals and draws them. The thing is that I wasn't sure how to add archiving. Should I archive each JBOval? I think this would work, but archiving an NSView doesn't seem very efficient. Any ideas on a better class design? Thanks.

  • copy HTML to UIPasteboard

    - by ManniAT
    Hi, I want to transfer HTML from my app to the iPhone mail application. I already have the HTML text - lest say <span style='color:red'Test</span I can place this to UIPasteBoard - but when I paste it to mail I get the html source. When I place the same string in a HTMLView - select it there and copy it it pastes as red text in mail. What do I have to do to place the string in the UIPasteBoard so that it pastes as red text to the mail application? I've been searching for "format types" - and found that UIPasteBoard returns "Aplle Web Archive pasteboard type" when I have the element (copied from UIWebView) in the clipboard. But setting this as type when adding the content to UIPasteBoard pastes nothing in the mail app. Manfred

  • fire and forget compared to http request

    - by cometta
    Hi, i looking for opinion from you all. I have a web application that need to records data into another web application database. I not prefer to use http request GET on 2nd application because of latency issue. I looking for fast way to save records on 2nd application quickly, i came across the idea of "fire and forget" , will JMX suit for this scenario? from my understanding jmx will gurantee message delivery. Let say i need to call at least 1000 random requests per seconds to 2nd application should i use jmx? http request? or xmpp instead?

  • replace file with hardlink to another file atomically

    - by Ben Clifford
    I have two directory entries, a and b. Before, a and b point to different inodes. Afterwards, I want b to point to the same inode as a does. I want this to be safe - by which I mean if I fail somewhere, b either points to its original inode or the a inode. most especially I don't want to end up with b disappearing. mv is atomic when overwriting. ln appears to not work when the destination already exists. so it looks like i can say: ln a tmp mv tmp b which in case of failure will leave a 'tmp' file around, which is undesirable but not a disaster. Is there a better way to do this? (what I'm actually trying to do is replace files that have identical content with a single inode containing that content, shared between all directory entries)

  • parsing string according to oracle operators with regex

    - by haluk
    Hi, Basically I was trying to replace the part of string with its actual value which comes immediately after oracle operators. I can do this for limited operators list like {=,,<} but I wonder that is there any way out to gather all the operators rather than giving them by hands? For instance, I have this string; "a = xyz", then I will replace xyz with lets say 3. But as you know we have bunch of operator namely "like,in,exists etc". So my string can also be this: "a like xyz". So what do you suggest me? Thanks.

  • FullCalendar: Change agendaDay background-color..

    - by Nick-ACNB
    While I have seen this question asked, I haven't seen the answer. Basically, I just want to be able to color the background-color of the TD from a certain range.. Say I have my calendar that has slot minutes every 15 minutes and from 9am to 9pm, I would like to only color differently 10am to 3pm. This information would be coming from a feed but that is not an issue. I haven't found the TDs relating to a set time inside the calendar. Perhaps I missed something? :) I am rather new to jQuery and fullCalendar. Also, another quick question that is unrelated to the main one: is it possible from an event handler to get the id of the calendar that launched it? I have multiple calendars on my page to simulate something like a Gantt view. This will let me be able to fetch the right feed and populate the right events. Thank you for your time.

  • How to create a folder for each item in a directory?

    - by Adrian Andronic
    I'm having trouble making folders that I create go where I want them to go. For each file in a given folder, I want to create a new folder, then put that file in the new folder. My problem is that the new folders I create are being put in the parent directory, not the one I want. My example: def createFolder(): dir_name = 'C:\\Users\\Adrian\\Entertainment\\Coding\\Test Folder' files = os.listdir(dir_name) for i in files: os.mkdir(i) Let's say that my files in that directory are Hello.txt and Goodbye.txt. When I run the script, it makes new folders for these files, but puts them one level above, in 'C:\Users\Adrian\Entertainment\Coding. How do I make it so they are created in the same place as the files, AKA 'C:\Users\Adrian\Entertainment\Coding\Test Folder'?

  • Is DataGrid a necessity in WPF?

    - by Jobi Joy
    I have seen a lot of discussions going on and people asking about DataGrid for WPF and complaining about Microsoft for not having one with their WPF framework till date. We know that WPF is a great UI technology and have the Concept of ItemsControl,DataTemplate, etc,etc to make great UX. Even WPF has got a more closely matching control- ListView, which can be easily templated to give better UX than a traditional Datagrid like display. And I would say a readymade DataGrid control will kill or hide a lot of creativity and it surely will decrease the innovations in User Experience field. So what is your opinion about the need of DataGrid in WPF as a Framework component? If you feel it is necessary then is it just because the world is so used to the DatGrid way of data display for many years? Some other threads having the discussion about DatGrid are here and here Link to WPF ToolKit - Latest WPF DatGrid

  • OpenGL es 2.0 Read depth buffer

    - by Brian
    Hi! As far as i know, we can't read the Z(depth) value in OpenGL ES 2.0. So I am wondering how we can get the 3D world coordinates from a point on the 2D screen? Actually I have some random thoughts might work. Since we can read the RGBA value by using glReadPixels, how about we duplicate the depth buffer and store it in a color buffer(say ColorforDepth). Of course there need to be some nice convention so that we don't lose any information of the depth buffer. And then when we need a point's world coordinates , we attach this ColorforDepth color buffer to the framebuffer and then render it. So when we use glReadPixels to read the depth information at this frame. However, this will lead to 1 frame flash since the colorbuffer is a weird buffer translated from the depth buffer. I am still wondering if there is some standard way to get the depth in OpenGL es 2.0? Thx in advance!:)

  • Sprite movement

    - by Lemmons
    Hi everyone. I'm ripping my hair out over this one. For some odd reason I cannot find out / think of how to move a sprite in SFML and or SDL. The tutorials I've looked at for both libraries state nothing about this; so I assume that it's more of a C++ thing than a library thing. So I was wondering; how do you move a sprite? (When I say move, I mean have the sprite "glide" across the window at a set speed)

  • Boost.Thread throws bad_alloc exception in VS2010

    - by the_drow
    Upon including <boost/thread.hpp> I get this exception: First-chance exception at 0x7c812afb in CSF.exe: Microsoft C++ exception: boost::exception_detail::clone_impl<boost::exception_detail::bad_alloc_> at memory location 0x0012fc3c.. First-chance exception at 0x7c812afb in CSF.exe: Microsoft C++ exception: [rethrow] at memory location 0x00000000.. I can't catch it, breaking at the memory location brings me to kernel32.dll and at this point I cannot say what's going on but it appears that the exception is thrown after the program ends and VS is capable of catching it. The testcase: #include <boost/thread.hpp> int main() { return 0; }

    Hi, I'm trying to install a speech recognition engine server side. (non commercial preferred since it's just for experimentation) The idea is to allow a user to say something from a website then whatever he/she says will show up on the screen (as text) I've read about many available softwares ranging from Microsoft Speech, Sphinx, Julius etc just not sure which one will perform best and easiest to install. Also do typically do I need to have root permission on my hosting to do this kind of stuff? I'm using a regular shared hosting right now. Thank you, Tee

  • In what case does IE8 block Javascript and how to avoid it ?

    - by e-satis
    I got a web site using jQuery, jQuery Tools and some handcrafted JS running performing graphical enhancements. While it's running smooth on FF, Safari and Chrome, IE blocks the script execution : There is nothing particularly more dangerous on this code than, let's say, on Netvibes. Why is even talking about activeX ? I'm using JS. And how can I prevent that ? I don't want my user to click on "I allow this website" to work. It would be like putting a big red absolute DIV reading "Live quick and never come back".
