    Hi all, I have this code: I need to replace 800px and 300px from database value; I tried both of the below. But still i am not getting the answer. Method 1: <div id="container" style="width:'<% Response.Write(width);%>'px; height:'<% Response.Write(height);%>'px; margin: 0 auto;overflow:hidden;"></div> Method 2: <div id="container" style="width:'<%# Eval("width");%>'px; height: <%# Eval("height");%>'px; margin: 0 auto;overflow:hidden;"></div> The value of height and width variables are defined in page_load() function int height=300; int width= 800; This is not affecting the resulting web page. Can anyone help me on this.

  • jQuery: event that tracks click in browser autocomplete

    - by Fernando
    I have a keyup event on an input. This event works fine for auto complete when you select a value and press enter. But it doesn't work when you click at an auto complete value. Is there an event that i can use in such case? I already tried the change one but it doesn't work. Thanks! Edit: Maybe i was not clear but i am referring to the autocomplete feature that browsers have. I am not trying to build my own. Example: I have the following event: $('.product').keyup(searchByProduct); When user clicks at this input the old values that he already typed shows up ( it's the browser that does this ). If he clicks on one of the values, the function searchByProduct is not called. Which event do i have to register to track this click ( and that the input content has changed )?

  • jQuery plugin to have Facebook styled search box with image thumbnails?

    - by Michael Mao
    Hello everyone: I will work on a search box with inspiration from Facebook where image thumbnails would be displayed besides the auto-suggested matches. This is the goal : link to sample image I wonder if there is any jQuery plugin that would just do this. I tried to search for a one but unable to find. If there is no plugin for this task, I'd like to know the basic plugins needed to implemented such an auto-suggest/image thumbnail display combination. Any suggestion and hint is welcomed. Thanks a lot!

  • Implementation of a C pre-processor in Python or JavaScript?

    - by grrussel
    Is there a known implementation of the C pre-processor tool implemented either in Python or JavaScript? I am looking for a way to robustly pre-process C (and C like) source code and want to be able to process, for example, conditional compilation and macros without invoking an external CPP tool or native code library. Another potential use case is pre-processing within a web application, within the web browser. So far, I have found implementations in Java, Perl, and of course, C and C again. It may be plausible to use one of the C to JavaScript compilers now becoming available. The PLY (Python Lex and Yacc) tools include a cpp implemented in Python.

  • Inconsistent Behavior From Declared DLL Function

    - by Steven
    Why might my GetRawData declared function return a correct value when called from my VB.NET application, but return zero when called from my ASP.NET page? The code is exactly the same except for class type difference (Form / Page) and calling event handler (Form1_Load, Page_Load). Note: In the actual code, #DLL# and #RAWDATAFILE# are both absolute filenames to my DLL and raw data file respectively. Note: The DLL file was not created by Visual Studio. Form1.vb Public Class Form1 Declare Auto Function GetRawData Lib "#DLL#" (ByVal filename() As Byte, _ ByVal byteArray() As Byte, _ ByVal length As Int32) As Int32 Private Sub Form1_Load(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles MyBase.Load Dim buffer(10485760) As Byte Dim msg As String, length As Integer = 10485760 Dim filename As String = "#RAWDATAFILE#" length = GetRawData(Encoding.Default.GetBytes(filename), buffer, length) Default.aspx.vb Partial Public Class _Default Inherits System.Web.UI.Page Declare Auto Function GetRawData Lib "#DLL#" (ByVal filename() As Byte, _ ByVal byteArray() As Byte, _ ByVal length As Int32) As Int32 Protected Sub Page_Load(ByVal sender As Object, _ ByVal e As System.EventArgs) Handles Me.Load Dim buffer(10485760) As Byte Dim msg As String, length As Integer = 10485760 Dim filename As String = "#RAWDATAFILE#" length = GetRawData(Encoding.Default.GetBytes(filename), buffer, length)

  • How to include named capture groups in java regex?

    - by jrummell
    I'm new to regex in Java and I can't figure out how to include named capture groups in an expression. I'm writing a ScrewTurn Image Converter for Confluence's Universal Wiki Converter. This is what I have: String image = "\\[image(?<align>auto)?\\|\\|{UP\\(((?<namespace>\\w+)\\.)?(?<pagename>[\\w-]+)\\)}(?<filename>[\\w- ]+\\.[\\w]+)\\]"; Pattern imagePattern = Pattern.compile(image, Pattern.CASE_INSENSITIVE); It's throwing this exception in Pattern.comiple(): java.util.regex.PatternSyntaxException: Unknown look-behind group near index 19 \[image(?<align>auto)?\|\|{UP\(((?<namespace>\w+)\.)?(?<pagename>[\w-]+)\)}(?<filename>[\w- ]+\.[\w]+)\] ^ I've used named capture groups like this before in C# (?<namedgroup>asdf), but not in Java. What am I missing?

  • c++ Array passing dilemma

    - by Thomas
    Hi, I am writing a function that takes a string, string pointer and an int. The function splits the string based on a set of rules and puts each token into an array. I need to return the array out of the function with the number of elements in the int variable etc. I am stuck as to how I return the array as I can not use auto other wise it is destroyed and I am reluctant to use new as I feel this is patchy. I have other ideas on how to go about this but would like to see how other people go about this first. I could also be wrong and it could be possible to pass an auto out of an array. I can also not use vectors so there goes a copy constructor.

  • Create a select tag with some options grouped and others not grouped

    - by dontangg
    I'm using Rails 3. I want to create a select tag with some options grouped and others not grouped. Options would look something like this: Income Auto Fuel Maintenance Home Maintenance Mortgage In this example, Income is not a group, but Auto and Home are. I see three helper methods grouped_options_for_select and grouped_collection_select, option_groups_from_collection_for_select. Is there a way to use a helper to do this or will I have to generate the HTML myself? I imagine I could use two different helpers to create the options and just append the results of both.

  • Why are items being placed below?

    - by Adam DePolo
    This is really confusing and I have never had this occur. For my computer, it is fine. But for anyone else's computer I have tried, it screws up.

  • Connection between Properties of Entities in Data Oriented Design

    - by sharethis
    I want to start with an example illustrating my question. The following way it is done in the most games. class car { vec3 position; vec3 rotation; mesh model; imge texture; void move(); // modify position and rotation void draw(); // use model, texture, ... }; vector<car> cars; for(auto i = cars.begin(); i != cars.end(); ++i) { i->move(); i->draw(); } Data oriented design means to process the same calculation on the hole batch of data at once. This way it takes more advantage out of the processor cache. struct movedata { vec3 position; vec3 rotation; }; struct drawdata { mesh model; imge texture; }; vector<movedata> movedatas; vector<drawdata> drawdatas; for(auto i = movedatas.begin(); i != movedatas.end(); ++i) { // modify position and rotation } for(auto i = drawdatas.begin(); i != drawdatas.end(); ++i) { // use model, texture, ... } But there comes a point where you need to find other properties according to an entity. For example if the car crashes, I do not need the drawdata and the movedata any more. So I need to delete the entries of this entity in all vectors. The entries are not linked by code. So my question is the following. How are properties of the same entity conceptually linked in a data oriented design?

  • Web app implementation question.

    - by John Berryman
    I would like to create a web app similar to Stack Overflow in that the users will have different "point" levels and that their capabilities within the web app will be different based upon their point level. Question: How can this best be implemented? How can it be implemented in a way that is un-hackable (i.e. accessing capabilities that should not be available)? I figure there are two ways to do this: server-side and client-side. For the server-side solution, for each page request you check who the user is and have the CGI rewrite the page so that the client only gets a web page with the intended capabilities. For the client-side solution, the server gives the client the fully capable app and it is the client's job to check the point level and to handicap the app appropriately. It seems like the client-side solution would be easier on the server, (which is really important for my app), but more susceptible to someone hacking and using capabilities unwarranted by their point level.

  • DataContractAttribute with Shared Assembly

    - by Sanju
    Hi All, Is it necessary to decorate custom objects with [DataContract] and [DataMember] when using shared assemblies (as opposed to auto proxy generation)? The reason I ask is that I have encountered the following scenario: Suppose the following object is implemented in my service: public class baseClass { Guid _guid; public baseClass() { _guid = Guid.NewGuid() } public Guid ReturnGuid { get {return _guid;}} } public class newClass : baseClass { int _someValue; public newClass {} public int SomeValue { get {return _someValue;} set {_someValue = value;} } } [ServiceContract] public IService { [OperationContract] newClass SomeOperation(); } In my client (with shared assemblie) I can happily recieve and use a serialized newClass when SomeOperation is called - even though I have not marked it as a DataContract. However, as soon as I do mark it with DataContract and use DataMember then it complains that set is not implemented on ReturnGuid in the base class. Could somebody explain why it works fine when I do not decorate with DataContract and DataMember. Many thanks.

  • Input multiple file names in windows open file dialog box

    - by goodiet
    Windows 7 allows you to select multiple files to open at once by using ctrl or shift key. The "File Name" input field at the bottom of the dialog box would auto populate with the following sample: "aaa.txt" "bbb.txt" "ccc.txt" "ddd.txt" I have 14,000 files in a folder and I only need a range of files (approx 500). When I use the shift key to select a range of files, the "File Name" field auto populates all 500 file names. Windows would cut me off at the 260th character when I try to paste in a pre-generated string into the "File Name" field. Is there a way to bypass the 260 character limit so it would accept my entire string with 500 file names?

  • Undefined template methods trick ?

    - by Matthieu M.
    A colleague of mine told me about a little piece of design he has used with his team that sent my mind boiling. It's a kind of traits class that they can specialize in an extremely decoupled way. I've had a hard time understanding how it could possibly work, and I am still unsure of the idea I have, so I thought I would ask for help here. We are talking g++ here, specifically the versions 3.4.2 and 4.3.2 (it seems to work with both). The idea is quite simple: 1- Define the interface // interface.h template <class T> struct Interface { void foo(); // the method is not implemented, it could not work if it was }; // // I do not think it is necessary // but they prefer free-standing methods with templates // because of the automatic argument deduction // template <class T> void foo(Interface<T>& interface) { interface.foo(); } 2- Define a class, and in the source file specialize the interface for this class (defining its methods) // special.h class Special {}; // special.cpp #include "interface.h" #include "special.h" // // Note that this specialization is not visible outside of this translation unit // template <> struct Interface<Special> { void foo() { std::cout << "Special" << std::endl; } }; 3- To use, it's simple too: // main.cpp #include "interface.h" class Special; // yes, it only costs a forward declaration // which helps much in term of dependencies int main(int argc, char* argv[]) { Interface<Special> special; foo(special); return 0; }; It's an undefined symbol if no translation unit defined a specialization of Interface for Special. Now, I would have thought this would require the export keyword, which to my knowledge has never been implemented in g++ (and only implemented once in a C++ compiler, with its authors advising anyone not to, given the time and effort it took them). I suspect it's got something to do with the linker resolving the templates methods... Do you have ever met anything like this before ? Does it conform to the standard or do you think it's a fortunate coincidence it works ? I must admit I am quite puzzled by the construct...

  • XNA Multi-Thread Jitters

    - by Ice Phoenix
    Hi guys, brand new question. Just implemented multi-threading into my XNA game as it was unable to keep up with using 1 processor. MT is all implemented fine and everything, however the player seems to jitter all over the spot every now and then. I originally thought it was a loss of data between the update and render, but even when i did the player update in the render it did the same thing. It's not a memory/processor issue as i'm no where near maxing out my RAM or processors. It's strange aswell because none of the other entities in the game seem to have any of these issues. Any ideas at all??

  • sequentially-consistent atomic load on x86

    - by axe
    Hello all, I'm interested in sequentially-consistent load operation on x86. As far as I see from assembler listing, generated by compiler it is implemented as a plain load on x86, however plain loads as far as I know guaranteed to have acquire semantics, while plain stores are guaranteed to have release. Sequentially-consistent store is implemented as locked xchg, while load as plain load. That sounds strange to me, could you please explain this in details? added Just found in internet, that sequentially-consistent atomic load could be done as simple mov as long as store is done with locked xchg, but there was no prove and no links to documentation. Do you know where can I read about that? Thanks in advance.

  • Is it guaranteed that new Integer(i) == i in Java?

    - by polygenelubricants
    Consider the following snippet: int i = 99999999; byte b = 99; short s = 9999; Integer ii = Integer.valueOf(9); // should be within cache System.out.println(new Integer(i) == i); // "true" System.out.println(new Integer(b) == b); // "true" System.out.println(new Integer(s) == s); // "true" System.out.println(new Integer(ii) == ii); // "false" It's obvious why the last line will ALWAYS prints "false": we're using == reference identity comparison, and a new object will NEVER be == to an already existing object. The question is about the first 3 lines: are those comparisons guaranteed to be on the primitive int, with the Integer auto-unboxed? Are there cases where the primitive would be auto-boxed instead, and reference identity comparisons are performed? (which would all then be false!)

  • Yii file upload issue

    - by user1289853
    Couple of months ago,I developed a simple app using YII,one of the feature was to upload file. The feature was working well in my dev machine,couple of days ago client found the file upload feature is not working in his server since deployment.

I've looked at jcaursel and jcaousellite but both have a pause of in auto mode or you have to specify how many items to slide. I just want it to move continously like a news ticker. Any suggestions on how to achieve this or how to customise jcaurousel or jcarouselite?

  • [as3] air for android - stage.setOrientation deprecated in AIR 2.5 so how do I do it now?

    as3 air for android using flash CS5 my problem: testing an AIR app on my droid 2 global (with slide out keyboard) using stage.addEventListener(StageOrientationEvent.ORIENTATION_CHANGE, handleOrientationChange); this is only fired when the i slide the keyboard out and not when I rotate the phone. I have tried this with the auto orientation on and off and with the aspect to portrait and landscape. actually the auto orientation option does not seem to make a difference on or off. I need the orientation to change when i rotate the phone. I know i can use the accelerometer to do this but the problem with that is when I click on a textField with the keyboard closed only the vertical keyboard pops up and i need the other one to pop up when holding the phone sideways.
