• Formatting an indented list in CSS

  - by Colen

  Hi, Let's say I have a list, with an arbitrary number of indentation levels, like so: Item Item Item Item Item Item Item Item Item Item Item If I'm displaying this list in an HTML document, how can I use CSS to handle the indentation? There might be an arbitrary number of indentation levels (although in practice there isn't going to be more than 5 or so). I don't want to create an "indent1" class that indents 10 pixels, an "indent2" class that indents 20 pixels, etc - that's clumsy. Is it possible to create a general rule that will indent by a certain distance based on an attribute value, or the position of an element in the hierarchy?

• Encoding issues with Spring and Freemarker

  - by Cameron

  I'm working on a project using Freemarker and Spring running on Jetty. It will involve displaying characters from many different countries so I'm trying to set the encoding to UTF-8. However, no matter what I do, it remains ISO-8859-1. I tried to create a filter in my web.xml and I've tried putting this response.setCharacterEncoding("UTF-8"); response.setContentType("text/html; charset=utf-8"); just before rendering the view. But when I load the page and click "View Page Info", the encoding is always ISO-8859-1. I've also tried hitting my app server directly to see if it was being affected by Apache but got the same result. Any help is appreciated.

• iPhone SDK mySQL

  - by Kevin

  Hello everybody, I'm starting on a new iPhone project, and this application mostly relies on mySQL. I have a mysql database running on my computer, and I need this application to send queries to the server to gain information. One example is creating and logging into an account. I have successfully done this on my windows vb.net application, but I know that objective c will be harder. This is basically getting text from the sql database and displaying it on the iPhone application. If someone could simply help me on that, I'll easily get started. So I hope that you guys help me out here :). Thanks Kevin

• Performing both client side and server side validation using jQuery and CodeIgniter

  - by Vasu

  What is the right way of doing both client side and server side validation using jQuery and CodeIgniter? I am using the jQuery form plugin for form submit. I would like to use jQuery validation plugin (http://docs.jquery.com/Plugins/Validation) for client side validation and CodeIgniter form validation on the server side. However the two don't seem to gel together (or I am unable to get my head around it). Can someone help please? Whether its a client side validation or server side validation, the user should see consistent UI displaying error messages next to the input fields.

• Linux Kernel - Refreshing VFS Dentry Cache

  - by Mike D

  I wrote a system call that opens a directory and gets the file object and the dentry struct. Im trying to list all entries including entries in subdirectories using the list_for_each() macro. The problem is its only displaying whats currently in the dentry cache. If I open the directory with nautilus then rerun the system call, all the entries are listed. Is there a way to check the exact list of entries or refresh the cache? f = s_open(tpath); fle = fget(f); d = fle->f_path.dentry; list_for_each ( position , &d->d_subdirs ) { dtmp = list_entry(position, struct dentry, d_u.d_child); ... } sys_close(f);

• webbrowser disable script debugging in Visual Basic 6

  - by me4245

  Hi, I want to disable script errors from popping up in a VB6 application. (I have VB6 installed on this machine). Currently, if I navigate to a particular page, it pops up saying "INternet Explorer Script Error: An error has ocurred in the script on this page" ... "Do you want to continue running scripts on this page?" Setting the webbrowser1.silent to 'true' does not work. Instead all that happens, is instead of displaying an error message, it starts up the actual 'script' debugger, and then exits the program. On a machine without the (visual studio) debugger, it still pops up a message asking to use the debugger, i.e., on Vista, (when silent is set to true). Manually changing the 'disable script debugging (other)' (and regular one), doesn't seem to working in MSIE (also testing version 6.0 for xp users). How do I disable script errors? Thanks in advance!

• Automatically tidy up JSP/JSF files

  - by er4z0r

  Hi, I am working on a webapplication and I do most of the XHTML stuff in an editor. Every once in a while I froget to close a tag or mess up the nesting (we all get distracted sometimes ;-)). So I commpile, package and run my webapp (using maven mvn clean package jetty:run-war only to notice that displaying the view (where I messed up the jsp) fails with an exception while trying to render. So I wondered: Is there some tool that I can include into my build-cycle that automatically catches and rectifies those careless mistakes?

• Python decoding issue with hashlib.digest() method

  - by Sorw

  Hello StackOverflow community, Using Google App Engine, I wrote a keyToSha256() method within a model class (extending db.Model) : class Car(db.Model): def keyToSha256(self): keyhash = hashlib.sha256(str(self.key())).digest() return keyhash When displaying the output (ultimately within a Django template), I get garbled text, for example : ?????_??!`?I?!?;?QeqN??Al?'2 I was expecting something more in line with this : 9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08 Am I missing something important ? Despite reading several guides on ASCII, Unicode, utf-8 and the like, I think I'm still far from mastering the secrets of string encoding/decoding. After browsing StackOverflow and searching for insights via Google, I figured out I should ask the question here. Any idea ? Thanks !

• [OpenGl] Loading new texture into already defined texture name

  - by Dan Vogel

  I have an OpenGl program in which I am displaying an image using textures. I want to be able to load a new image to be displayed. In my Init function I call: Gl.glGenTextures(1, mTextures); Since only one image will be displayed at time, I am using the same texture name for each image. Each time a new image is loaded I call the following: Gl.glBindTexture(Gl.GL_TEXTURE_2D, mTexture[0]); Gl.glTexImage2D(Gl.GL_TEXTURE_2D, 0, Gl.GL_LUMINANCE, mTexSizeX, mTexSizeY, 0, Gl.GL_LUMINANCE, Gl.GL_UNSIGNED_SHORT, mTexBuffer); Gl.glTexParameteri(Gl.GL_TEXTURE_2D, Gl.GL_TEXTURE_MIN_FILTER, Gl.GL_LINEAR); Gl.glTexParameteri(Gl.GL_TEXTURE_2D, Gl.GL_TEXTURE_MAG_FILTER, Gl.GL_LINEAR); The first image will display as expected. However, all images load after the first, display as all black. What am I doing wrong?

• UIWebView - get total height of contents using Javascript

  - by Emil

  Hey. I'm trying to use a UIWebView for displaying content higher than the screen of the iPhone, without needing to scroll in the webView itself. For that, I need a way to get the total document size, including the scrollable area. I have tried a number of different Javascript solutions: (document.height !== undefined) ? document.height : document.body.offsetHeight // Returns height of UIWebView document.body.offsetHeight // Returns zero document.body.clientHeight // Returns zero document.documentElement.clientHeight // Returns height of UIWebView window.innerHeight // Returns height of UIWebView -2 Can you think of any other way to do it? Thanks.

• Change UIActionSheet after doing it's job

  - by mongeta

  Hello, I have to import some XML data into my app. Now I open a UIActionSheet and add as a subview a UIActivityIndicatorView. Initially I show a progress wheel and a button with 'Cancel'. When the XML has been imported, I want to hide the progress wheel (this it's easy) and change the button into a 'Done' button, all in the same UIActionSheet. What I'm doing now is closing the UIActionSheet with the option dismissWithClickedButtonIndex, but I don't like this way because it's the same as pressing 'Cancel', and then I show an UIAlertView displaying "All data has been imported". Is this possible ? thanks, regards, r.

• Refreshing UIScrollView / Animation, timing (Objective-C)

  - by Switch

  I have a UIScrollView that is displaying a list of data. Right now, when the user adds one more item to the list, I can extend the content size of the UIScrollView and scroll down smoothly using setContentOffset and YES to animated. When the user removes an item from the list, I want to resize the content size of the UIScrollView, and scroll back up one step also in an animated fashion. How can I get the ordering right? Right now, if I resize the content size before scrolling back up, the scroll isn't animated. I tried scrolling back up before resizing the content size, but that still didn't give a smooth transition. Is there a way to finish the scrolling animation BEFORE resizing the content size? Thanks

• How can I prompt user for additional permissions on page load?

  - by Rew

  Note: The application I'm building is a website type Facebook Application that uses Facebook Connect. I can prompt the user with a request for Extended Permissions using the following FBML code: <fb:prompt-permission perms="read_stream,publish_stream"> Grant permission for status updates </fb:prompt-permission> Taken from here. This creates a link on the page that must be clicked by the user in order to trigger the prompt to display. My question is: Is it possible to display this prompt automatically, when the page loads, without requiring the user to click on the link? Also, in reply to the answer below, I'd like to avoid displaying the link. Would prefer a neat way to do this, if that fails the least dirty method will do :-)

• ASP.Net MVC 2: How to keep values in the model between posts

  - by Andreas

  I have an edit view that is displaying some model properties as plain text and other model properties as input fields. My problem is that the model properties displayed as plain text are null when the model is returned to the view after a validation error. How do I retain the model values when I don't have input fields for all properties? What is best practice? My first thought is to keep the values of these properties in hidden input elements. <%= Html.HiddenFor(model => model.CustomerName) %> Is this considered a correct solution? Thanks Andreas

• Using Bitmap.LockBits and Marshal.Copy in IronPython not changing image as expected

  - by Leonard H Martin

  Hi all, I have written the following IronPython code: import clr clr.AddReference("System.Drawing") from System import * from System.Drawing import * from System.Drawing.Imaging import * originalImage = Bitmap("Test.bmp") def RedTint(bitmap): bmData = bitmap.LockBits(Rectangle(0, 0, bitmap.Width, bitmap.Height), ImageLockMode.ReadWrite, PixelFormat.Format24bppRgb) ptr = bmData.Scan0 bytes = bmData.Stride * bitmap.Height rgbValues = Array.CreateInstance(Byte, bytes) Runtime.InteropServices.Marshal.Copy(ptr, rgbValues, 0, bytes) for i in rgbValues[::3]: i = 255 Runtime.InteropServices.Marshal.Copy(rgbValues, 0, ptr, bytes) bitmap.UnlockBits(bmData) return bitmap newPic = RedTint(originalImage) newPic.Save("New.bmp") Which is my interpretation of this MSDN code sample: http://msdn.microsoft.com/en-us/library/5ey6h79d.aspx except that I am saving the altered bitmap instead of displaying it in a Form. The code runs, however the newly saved bitmap is an exact copy of the original image with no sign of any changes having occurred (it's supposed to create a red tint). Could anyone advise what's wrong with my code? The image I'm using is simply a 24bpp bitmap I created in Paint (it's just a big white rectangle!), using IronPython 2.6 and on Windows 7 (x64) with .Net Framework 3.5 SP1 installed.

• Blackberry.location API not working correctly

  - by chibineku

  I am experimenting with making Blackberry widgets but having a little trouble. My first trial involves displaying a button which, when clicked, calls a JavaScript function that should alert the phones latitude and longitude. The function looks: function whereAmI() { var latitude = blackberry.location.latitude; var longitude = blackberry.location.longitude; alert("Lat: "+latitude+", Long: "+longitude); } But it only ever alerts "Lat: 0, Long: 0". I've checked and my GPS seems to be working ok. I'm running OS 5.* on a Curve 8900. Any help would be appreciated :)

• Hot to trigger saved password autofill in browsers?

  - by Aleksander Kmetec

  I have a web application written in pure JavaScript (no pre-generated HTML except for the document which loads all the JS files). This app contains a login form which is created dynamically when the document.ready event event is triggered. I trick the browser into displaying the "Remember password?" dialog by posting the login form into a hidden iframe before logging in using ajax (in Firefox the password appears on the saved password list, so this part obviously works) but saved passwords never get filled in after the login screen is loaded again at a later time. The same thing happens in Firefox and Safari. Is there something I can do or some function I can call to trigger autofill?

• AsyncTask, RejectedExecutionException and Task Limit

  - by Samuh

  I am fetching lots of thumbnails from a remote server and displaying them in a grid view, using AsyncTask. The problem is, my grid view displays 20 thumbnails at a time, so that creates 20 AsyncTasks and starts 20 executes, one per thumbnail. I get RejectedExecution exception in my code. I recall reading somewhere that there is a limit to number of tasks that AsyncTask can have in its queue at a time, i might be hitting that. Was this bar lifted? Is there a way to increase this limit? Is it safe to just ignore this exception?(by having an empty catch(RejectedException e){} block?) I am running this code on Android 1.6 emulator and the API level in my code(minSDKVersion is 3). [EDIT: Added SDK and API level info]

• Communicating with the PC via USB connection in Android

  - by Danny Singh

  I'm fairly new to android programming and need some information for a 4th year forensics course project. Basically I am trying to create a suite of tools for live analysis of an android phone. I know how to get the information I need on the phone, but I was wondering if there was a way to communicate that information back to the PC? I want to be able to run a program from a PC, which, when the phone is docked, will allow the user to access information about the phone (ie currently running services/processes, bluetooth/wifi connections, etc). I have a bunch of methods that will run on the phone and get all the information, but I want to be able to call those methods from the PC, execute on the phone, then have the information sent back to the PC to display to the user instead of just displaying it on the phone. This is to leave as small a footprint on the phone as possible. Thanks a lot.
