• WebSQL Databases between two different pages?

  - by Srikanth Rayabhagi

  Is there any particular way in which we can access the Web SQL Database of one page, by other page. To make it more clear, suppose a.com creates the database DB and store some info. Now b.com comes and want to access the same database DB. Is there a way? Or are there any alternatives to do this? I tried to implement in HTML5 and Javascript but the databases as well as the localStorages are confining only to particular pages, I want this to be cross the pages.

• Enableeventvalidation in web user control

  - by Khushi

  Hi, i have a web user control containing a repeater. The repeater contains three buttons. On button click it gives the following error : Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" % in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. Since user control does not have page directive, so i changed the enableEventValidation to false, but it restricted the itemcommand event of the repeater. Can someone guide me, how to solve this problem?

How do i detect if the IP forwarding is happening/ get the real ip address of the person.

• Can JavaScript be overused?

  - by ledhed2222

  Hello stackoverflow, I'm a "long time reader first time poster", glad to start participating in this forum. My experience is with Java, Python, and several audio programming languages; I'm quite new to the big bad web technologies: HTML/CSS/JavaScript. I'm making two personal sites right now and am wondering if I'm relying on JavaScript too much. I'm making a site where all pages have a bit of markup in common--stuff like the nav bar and some sliced background images--so I thought I'd make a pageInit() function to insert the majority of the HTML for me. This way if I make a change later, I just change the script rather than all the pages. I figure if users are paranoid enough to have JavaScript turned off, I'll give them an alert or something. Is this bad practice? Can JavaScript be overused? Thanks in advance.

• 'Loading' web page for async call

  - by Sieg

  I have a simple web page in ASP.NET / C#. Currently to fully render the data I require calling a block of code that runs on background threads and can take multiple minutes to complete. I've got it to the point (using the async attribute on the page declaration) to execute and return fine with the html once it's done. What I'd like it to do is allow me to return immediately with a 'loading page' of some sort and then have that page be updated when the background work has been completed. Right now I get nothing on the page while the background work is being processed. Any ideas on the best way or clever way to do that would greatly be appreciated! Thanks, Sieg

• How should 4 decimals places behave, being simple yet powerful

  - by vener

  I have a UI question that troubled me on the best method to handle 4 decimal places for prices. In an table already cramped full of data, I would want to simplified the interface to make it not so cluttered. The actual current UI is shown below. http://i41.tinypic.com/bg5tub.jpg The problem is, for a unit price/units/D.Price and Dis.(Discount) to have 4 decimal places ($0.3459) is quite rare but it still happens (5 in 100 entries). This will result a lot of junk decimal places, cluttering up the interface. What is the best solution to this problem? In short, I want to declutter it yet maintain the precision. Note: This is web app

• Sharing data between two instances in a load balanced java web application

  - by rabbit

  I want to cache data in a java web application deployed on multiple instances. We are using spring 2.5.6. What is the easiest caching library to configure and use with spring? I have heard of EH Cache, but the configuration is too cumbersome. The requirement is that a spring scheduler will run and set some flags. These flags are accessible from all load balanced instances. But since the scheduler runs only on one instance the flag is set only on that jvm. So how do i make these updated flag values available to all load balanced instances?

• Perform tasks with delay, without delaying web response (ASP.NET)

  - by Tomas Lycken

  I'm working on a feature that needs to send two text messages with a 30 second delay, and it is crucial that both text messages are sent. Currently, this feature is built with ajax requests, that are sent with a 30 second javascript delay, but since this requires the user to have his browser open and left on the same page for at least 30 seconds, it is not a method I like. Instead, I have tried to solve this with threading. This is what I've done: Public Shared Sub Larma() Dim thread As New System.Threading.Thread(AddressOf Larma_Thread) thread.Start() End Sub Private Shared Sub Larma_Thread() StartaLarm() Thread.Sleep(1000 * 30) StoppaLarm() End Sub A web handler calls Larma(), and StartaLarm() and StoppaLarm() are the methods that send the first and second text messages respectively. However, I only get the first text message delivered - the second is never sent. Am I doing something wrong here? I have no deep understanding of how threading works in ASP.NET, so please let me know how to accomplish this.

• selecting all text within a div on a single left click with javascript

  - by tstyle

  I have a simple non-clickable link within a div that looks like this: It's meant to be a sharable link that the user can copy paste into other things. For usability purposes, I want a single left click anywhere within the div to select the entire link: I don't know much about, javascript/web programming, so I've tried the following: <div id="share_link" onClick="select_all('share_link')"><%= request.url %></div> and this javascript <script type="text/javascript"> function select_all(id) { document.getElementById(id).focus(); } </script> This doesn't work. I'd like to know what's the simplest thing I should do to achieve what I want. I thought about changing the div to a text input or the text within to be a link, but ideally the content within should be read-only, non-editable, and non-clickable

• downloading full page text from a web domain

  - by user362808

  Howdy, folks! First time here -- thought I'd field a question on behalf of a coworker. Somebody in my lab is doing a content analysis (e.g. reading an article or transcript line by line and identifying relevant themes) of the web presences of various privatized neuroimaging centers (e.g. http://www.canmagnetic.com/). She's been c/ping entire site maps by hand, and I know I could slap something together with Python to follow links and dump full text (with line numbers) for her, but I've never actually done anything quite like this. Any ideas for how I'd get started? Cheers, -alex

• Can you /should you learn SEO techniques

  - by Mark

  I know very little about Search engine optimization however from discussions with other I am now unsure where to start. Are there any books or do these date so quickly that they are obsolete? Do all website give you mis-information or are there any reliable sources? Is it just a case of trial and error and in turn experience? Is it event worth learning the techniques as search engines change their algorithms so regularly? I wonder if it just better to spend the time to ensure you have a regularly updated will written web site with quality content, site map, quality links etc..

• How can I use Amazon's API in PHP to search for books?

  - by TerranRich

  I'm working on a Facebook app for book sharing, reviewing, and recommendations. I've scoured the web, searched Google using every search phrase I could think of, but I could not find any tutorials on how to access the Amazon.com API for book information. I signed up for an AWS account, but even the tutorials on their website didn't help me one bit. They're all geared toward using cloud computing for file storage and processing, but that's not what I want. I just want to access their API to search info on books. Kind of like how http://openlibrary.org/ does it, where it's a simple URL call to get information on a book (but their databases aren't nearly as populated as Amazon's). Why is it so hard to find the information I need on Amazon's AWS site? If anybody could help, I would greatly appreciate it.

• Refreshing the asp.net web page after validation

  - by user279521

  Hi, I have an asp.net web page (C# 2008) where the user would enter an EmployeeID, and when they tab out of the textbox, they get a messagebox prompting them to select one of two values from a dropdown listbox. The code for the message prompt in the codebehind is : Response.Write("<script>window.alert('Please select Alpha or Beta')</script>"); After the prompt is displayed, and the user clicks "ok" and returns to the page, the text on the page appears distorted (the text in labels are a size larger, the labels get wrapped to another line etc) I tried putting a Response.Redirect("UserProfileMaint.aspx"); after the messagebox in the codebehind, but now, the messagebox does not appear; I want to display the messagebox validation, and ensure the appearance of the text on the page is not distorted. How can I do this?

• Save response from certain WEB resources while recording scenario

• Creating folders and uploading a file without using a web browser

  - by Ashpak

  I am using the Java Api We have a web application wherein we want our file to be uploaded on an on_click even on some submit button. We don't want the browser to prompt us to enter the username and password to get the access token. Instead, we can provide the username and the password through the code so that we get the access token and the file will be uploaded directly. Right now, OAuth 2 requires that we enter the username and password to be entered through the browser. Reading through the post, I see that we can authenticate for the first time, obtain a refresh token and then keep on refreshing that token periodically. But our application requirements does not allow for this work-flow. Is there any way to automate the process of entering the user credentials using Java code. or Is there any library that will keep the browser away from the process.

• Getting Results from a Web SQL database

  - by andrew8088

  I'm playing around with the new Web SQL databases. Is there a way to return results from a SELECT statement? Here's my example: function getTasks (list) { db.transaction(function (tx) { list = list || 'inbox'; tx.executeSql("SELECT * FROM tasklist WHERE list = ?", [list], function (tx, results) { var retObj = [], i, len = results.rows.length; for ( i = 0; i < len; i++ ) { retObj[i] = results.rows.item(i); } return retObj; }); }); } The getTasks function is returning before the success callback does; is there a way to get the results out of the executeSql method, or do I have to do all the processing within the callback?

• Appending to InnerHtml without rest of contents flicking

  - by centro

  I have a div element with some formatted images. On user request, I load additional images asynchronously, without postback, and append the result (formatted HTML for new images) to the div element using JavaScript: function onRequestComplete(result) { var images = document.getElementById('images'); images.InnerHtml += result; } All is okay, except that part when images in the panel loaded previously flicker after the HTML is appended. As far I understand, the panel is reconstructed, not just new HTML is appended to its bottom. So it isn't web 2.0 behavior. How can it be done without flicking? Thanks in advance.

• Which route should i take for web hosting?

  Hi I am setting up a small website sort of like an online portfolio. I made the mistake of signing up for shared-web hosting before asking if they supported stored procedures which took me half the day to figure out they didn't. Basically i'm looking for a site that offers me PHP5.4+/ Mysql 5.5 + with support for triggers/stored procedures/ and if possible MyphpAdmin 3.5.1. I also have a domain name I already registered and which I would like to use. What is my best option to look for hosting provider which offers this functionality or to setup a VPS?

• Where should the web server root directory go in linux?

  - by Xeoncross

  I see that Apache and Nginx both use var/www as their web root - but that directory is not covered in the Filesystem Hierarchy Standard. I also see some servers with the web root in the /home/username/www directory. So where does the web root go? Or rather, where should it go most of the time for the common web server?
