• White bar at the bottom of root view!

  - by Sam

  Hi, I have two view controllers in the app. When the app starts, the layout of the root view controller's view is just fine. When a button is clicked, the view controller switches to the other one - which shows fine too. However, when the view is switched back to the root view, the contents are shifted UP by about 20 pixels, leaving a white bar at the bottom! - and it was not there when the app had started. Has anyone seen this? Any idea what's going on there? Thanks, Sam.

• Android VideoView resume and seekTo

  - by Chris

  I am playing a Video using a VideoView in my app. On the click of a button, it records the current position of the video, and the app opens up the browser with some url. On pressing the back button, the app comes back to video app and resumes the video from where it left off. I looked at the Android Activity lifecycle and saw that onStart() method gets called once the video activity comes to the foreground. So I am creating my layout in onStart() and playing the video by seeking to the current position. My problem is that when the video resumes, it buffers from the start and then seeks to. Since it already buffered the first time, is there a way to eliminate buffering again while doing a seekTo? Thanks Chris

• Colspan in IE7/8 not respected

  - by Stefan Kendall

  The DOM looks like this: <table> <tr> <td>a</td>...<td>g</td> </tr> <tr> <td colspan="3"> <table> ... </table> </td> </tr> <tr> <td></td>...<td></td> </tr> </table> Any idea why this wouldn't work in IE? I tried setting width:auto on the TD holding the inner table, and table-layout:fixed isn't viable because the tabular data is generated dynamically. What could be going wrong?

• Logging with log4j on tomcat jruby-rack for a Rails 3 application

  - by John

  I just spent the better part of 3 hours trying to get my Rails application logging with Log4j. I've finally got it working, but I'm not sure if what I did is correct. I tried various methods to no avail until my various last attempt. So I'm really looking for some validation here, perhaps some pointers and tips as well -- anything would be appreciated to be honest. I've summarized all my feeble methods into three attempts below. I'm hoping for some enlightenment on where I went wrong with each attempt -- even if it means I get ripped up. Thanks for the help in advance! System Specs Rails 3.0 Windows Server 2008 Log4j 1.2 Tomact 6.0.29 Java 6 Attempt 1 - Configured Tomcat to Use Log4J I basically followed the guide on the Apache Tomcat website here. The steps are: Create a log4j.properties file in $CATALINA_HOME/lib Download and copy the log4j-x.y.z.jar into $CATALINA_HOME/lib Replace $CATALINA_HOME/bin/tomcat-juli.jar with the tomcat-juli.jar from the Apache Tomcat Extras folder Copy tomcat-juli-adapters.jar from the Apache Tomcat Extras folder into $CATALINA_HOME/lib Delete $CATALINA_BASE/conf/logging.properties Start Tomcat (as a service) Expected Results According to the Guide I should have seen a tomcat.log file in my $CATALINA_BASE/logs folder. Actual Results No tomcat.log Saw three of the standard logs instead jakarta_service_20101231.log stderr_20101231.log stdout_20101231.log Question Shouldn't I have at least seen a tomcat.log file? Attempt 2 - Use default Tomcat logging (commons-logging) Reverted all the changes from the previous setup Modified $CATALINA_BASE/conf/logging.properties by doing the following: Adding a setting for my application in the handlers line: 5rails3.org.apache.juli.FileHandler Adding Handler specific properties 5rails3.org.apache.juli.FileHandler.level = FINE 5rails3.org.apache.juli.FileHandler.directory = ${catalina.base}/logs 5rails3.org.apache.juli.FileHandler.prefix = rails3. Adding Facility specific properties org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/rails3].level = INFO org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/rails3].handlers = 4host-manager.org.apache.juli.FileHandler Modified my web.xml by adding the following context parameter as per the Logging section of the jruby-rack readme (I also modified my warbler.rb accordingly, but I did opted to change the web.xml directly to test things faster). <context-param> <param-name>jruby.rack.logging</param-name> <param-value>commons_logging</param-value> </context-param> Restarted Tomcat Results A log file was created (rails3.log), however there was no log information in the file. Attempt 2A - Use Log4j with existing set up I decided to go Log4j another whirl with this new web.xml setting. Copied the log4j.jar into my WEB-INF/lib folder Created a log4j.properties file and put it into WEB-INF/classes log4j.rootLogger=INFO, R log4j.logger.javax.servlet=DEBUG log4j.appender.R=org.apache.log4j.RollingFileAppender log4j.appender.R.File=${catalina.base}/logs/rails3.log log4j.appender.R.MaxFileSize=5036KB log4j.appender.R.MaxBackupIndex=4 log4j.appender.R.layout=org.apache.log4j.PatternLayout log4j.appender.R.layout.ConversionPattern=%d{dd MMM yyyy HH:mm:ss} [%t] %-5p %c %x - %m%n Restarted Tomcat Results Same as Attempt 2 NOTE: I used log4j.logger.javax.servlet=DEBUG because I read in the jruby-rack README that all logging output is automatically redirected to the javax.servlet.ServletContext#log method. So I though this would capture it. I was obviously wrong. Question Why didn't this work? Isn't Log4J using the commons_logging API? Attempt 3 - Tried out slf4j (WORKED) A bit uncertain as to why Attempt 2A didn't work, I thought to myself, maybe I can't use commons_logging for the jruby.rack.logging parameter because it's probably not using commons_logging API... (but I was still not sure). I saw slf4j as an option. I have never heard of it and by stroke of luck, I decided to look up what it is. After reading briefly about what it does, I thought it was good of a shot as any and decided to try it out following the instructions here. Continuing from the setup of Attempt 2A: Copied slf4j-api-1.6.1.jar and slf4j-simple-1.6.1.jar into my WEB-INF/lib folder I also copied slf4j-log4j12-1.6.1.jar into my WEB-INF/lib folder Restarted Tomcat And VIOLA! I now have logging information going into my rails3.log file. So the big question is: WTF? Even though logging seems to be working now, I'm really not sure if I did this right. So like I said earlier, I'm really looking for some validation more or less. I'd also appreciate any pointers/tips/advice if you have any. Thanks!

• Fit <TD> height to page

  - by ssg

  Consider a table with three rows with heights 10, *, 10. I'd like the middle cell to be high enough to fit to the page vertically. Unfortunately "height:100%" doesn't work at table, tr, or td level, possibly due to standards. Even if it happens to work, I don't want 100%, I want 100% of clientHeight-20px :) I can always write script to calculate remaining clientHeight but I wonder if it can be achieved in HTML/CSS standards. NOTE: I'm using table just for layout, if there are other ways to lay them down in a better way I'm ok with those approaches too.

• Android and config.xml

  - by synic

  Looking in the android sdk folders, I've found a file called values/config.xml. This seems to be somewhere that you can define values for later use in layouts and animations. Given the config.xml: <resources> <string name="config_somePadding">50dip</string> </resources> How would I reference this to use as the layout_height in a layout xml file? @string/config_somePadding is actually the only one I've found that doesn't throw an error in Eclipse (even though there isn't a config_somePadding in values/strings.xml), but it appears to just put an empty string.

• weird stuff with asp.net button CSS class

  - by Alexander

  I have the following button: <Club:RolloverButton runat="server" ValidationGroup="Login1" Text="Login" ID="LoginButton" CommandName="Login" CssClass="links" /> .links { display: block; width: 96px; padding: 2px 0px 2px 0px; background: #A53602; text-align: center; text-transform: uppercase; font-size: 10px; color: #FFFFFF; } When this button shows up the first time it shows the style correctly, however if I hover my mouse over this button the layout turns into a standard button, why is that??

Is it possible? Should I use another layout? Thanks a lot.

• Sanitize Content: removing markup from Amazon's content

  - by StackOverflowNewbie

  I'm using Amazon Web Service to get product descriptions of various items. The problem is that Amazon's content contains mark up that is sometimes destructive to the layout of my web page (e.g. unclosed DIVs, etc.). I want to sanitize the content I get from Amazon. My solution would be to do the following (my initial list so far): Remove unnecessary tags such as div, span, etc. while keeping tags like p, ul, ol, etc. Remove all attributes from all the tags (e.g. seems like there are style attributes in some of the tags) Remove excess white space (e.g. multiple spaces, carriage returns, new lines, tabs, etc.) Etc. Before I go off trying to build my solution, I'm wondering if anyone has a better idea (or an already existing solution). Thanks.

• Accessing a module's action rendered output

  - by Flavius

  Hi. I'm writing an "Account" module which should take care of everything about accounts: registration, login/logout, user administration, password recovery, account activation, etc. So I thought it would be best to reuse whatever the module's DefaultController::actionRegister() generates to show on the main page. So my question is: how to create a new "sub request" (similar to CController::forward()) from any controller (either SiteController, read: from views/layouts/main.php, or another controller, eventually of another submodule) to a given module/controller/action? I've tried with $this-forward() from within my application layout without success: it shows a blank page, no error whatsoever. Thanks

• Struts2 dynamic form elements

  - by bozo

  Hi, I would like to create little higer-level framework on top of Stuts2 which can take form element description from Action and render a complete form, in order to avoid having a separate JSP files with hardcoded form elements for every form in a large web application (so if I manage to do this I will have just a few generic JSPs for data form and few for layout). Application is extremely data-driven. My idea is to create form description using custom objects in the Action (i.e. Button, TextInput etc.) and then to create a single JSP page that will render eveything out. What is the best way of doing this? Can you propose some concrete way to do this? I don't want to write something if I can reuse the existing code with some effort. Any ideas are appreciated. Kind regards, Bozo

• Including inline javascript using content_for in rails

  - by TenJack

  I am using content_for and yeild to inject javascript files into the bottom of my layout but am wondering what the best practice is for including inline javascript. Specifically I'm wondering where the put the script type declaration: <% content_for :javascript do %> <script type="text/javascript"> ... </script> <% end %> or <% content_for :javascript do %> ... <% end %> <script type="text/javascript"> <%= yield :javascript %> </script> <% end %> I am using the first option now and wondering if it is bad to include multiple ... declarations within one view. Sometimes I have partials that lead to this.

• Looking for help with a design for a simple C# calendar app.

  - by Vladislav

  As a personal project, I'm putting together a C# WPF calendar. I'm stuck on coding the calendar screen - specifically, the 5x7 grid of days. I've first tried to code it using elements like Panels, Labels, and Buttons. I've decided that was too cumbersome. I've then decided to use GDI to draw the calendar myself. I now have a wonderful layout - but I'm not sure how to handle interactive regions of the calendar. (Say, Previous/Next month, clicking on any particular day...) After rendering the calendar screen, should I be creating button objects for all those tasks, and assigning onClick handlers to them? Or is there an alternative solution? Thanks in advance. -Vladislav

• sql server 2005 reporting services-- how to use multiple datasets in report

  - by larryq

  Hi everyone, I'm new to SQL Server reporting services, and am trying to decipher an existing report. It's nothing too bad, but I notice it does have two report datasets defined. (They are generated via separate stored procedures) I'm trying to figure out where and how the report datasets are linked together so the Fields collection has both sets of columns available and the report has a single rowset to traverse. Is there a section in the report layout where a joining of datasets is defined? I'm using Visual Studio 2005 to design and preview the report fwiw. Thanks for your help!

• Is possible to auto-import a module from a diferent subfolder in other subfolder?

  - by mamcx

  I have a kind of plugin system, with this layout: - Python -- SDK -- Plugins ---- Plugin1 ---- Plugin2 All 3 have a __init__.py file. I wonder if is possible to be able to do import SDK from any plugin (as if SDK was in the site-packages folder). I'm in a situation where need to deploy, update, delete, add or change SDK files or any of the plugins under non-admin accounts, and wonder if I can get SDK in a clean way (I could sys.path.append in all plugins but I wonder if exist a better option). I imagine that using this in the Plugins init coulkd work: import sys import os ROOT_DIR = os.path.abspath(os.path.join(os.path.dirname(__file__),'..')) print ROOT_DIR sys.path.append( ROOT_DIR ) But clearly is not executed this code (I imagine init was auto-magicalled executed in the load of the module :( )

• Justified navigation buttons

  - by Kaivosukeltaja

  I'm trying to create the primary navigation menu for a website that will have a variable amount of primary menu items. The navigation bar is horizontal and has a width of 738px. I would like to have the leftmost item 18px from the left and the rightmost item 18px from the right edge of the element, with the other menu items spread evenly between them. I'm using a tableless layout. So far I haven't been able to make it work exactly like I want. Setting margin: auto doesn't seem to help, and I can't keep the 18px margin on both sides using a table. One idea was to use text-align: justify but it doesn't justify single lines. Is there a simple or less simple way of doing this, or am I going to have to ask the AD to relax his visual requirements?

• How do you handle very old browsers on your site?

  - by Alex

  Hi. We have a non-profit web site that got about 5 million hits in May. Of those, about 5,700 were from IE 5.x or lower; about 4,000 were from folks with Netscape 4.x or lower. We know that the current site's layout works for newer browsers and we're testing it on IE6 as well (along with Chrome, Opera, Safari, and Firefox). How do you handle the folks with the older browsers? Because of jQuery libraries and such, the pages might not function correctly on those old browsers. Is there an easy way to show a text-only version on browsers that can't handle the CSS and jQuery goodies? How do large sites handle this sort of thing? I've used the @embed to hide the stylesheet from Netscape 4.x, but not sure beyond that.

• Multiple shapes on Android

  - by LucaB

  Hi Hi I'm trying to build a layout where some shapes will popup every 2 seconds. If the user will click one of these shapes, they have to disappear. What is the correct way of doing this? I thought about a thread, but i missed out. Here's my code at the moment (is not working): public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); l = new LinearLayout(this); setContentView(l); int counter = 1; View v = new CustomDrawableView(this,20,50); l.addView(v); Thread t = new Thread() { public void run() { while (true) { Log.i("THREAD","INSIDE"); View h = new CustomDrawableView(c, (int)Math.round(Math.random()*100), (int)Math.round(Math.random()*100)); SystemClock.sleep(2000); l.addView(h); } } }; t.start(); }

• Internet Explorer generates extra br

  - by ahsteele

  I have an issue where Internet Explorer is generating an additional br element that is not in my source. The additional br effects the page's layout and is visible when using the developer tool. I've tried removing all hard returns between the surrounding elements but the additional br persists. Firefox and Chrome do not have this issue. Ideas on what I can do to fix the issue? Instead of First line. Second line. I get First line Second line. Code Example <asp:ImageButton ID="RemoveItem" AlternateText="Remove Item" ImageUrl="~/img/buttons/remove.png" runat="server" CssClass="remove" CommandName="Remove" OnCommand="RemoveCartItem_Command" /> <br runat="server" id="TotalBreak" />

• GUI Design - Roleselection with two lists, selected roles on the right, or left list?

  - by subes

  Hi, image two lists for selecting roles for a new user creation in an administrator frontend. One list has all available roles in it and another has the selected roles in it. Between those lists are buttons to move elements from one list to another. Thus the layout is horizontal with [List] [Buttons] [List]. Now to the question: Should the selected elements be on the left, or the right list? Intuitively some people I asked say, that the selected elements have to be on the right list. But some other people follow some sort of guideline that says, that the more important stuff in a frontend has to be on the left side. Also they think the selected elements are more important than the non-selected and so the selected ones have to be on the left side. Whats your opinion?
