  • How do I make Pseudo classes work with Internet Explorer 7/8?

    - by Mel
    I've written the following code to create a three-column layout where the first and last columns have no left and right margins respectively: #content { background-color:#edeff4; margin:0 auto 30px auto; padding:0 30px 30px 30px; width:900px; } .column { float:left; margin:0 20px; } #content .column:nth-child(1) { margin-left:0; } #content .column:nth-child(3) { margin-right:0; } The problem is that this code does not work in Internet Explorer 7 and 8? The only pseudo class I can use with IE (in this case) would be "first-child," but this does not eliminate the right margin on the third and last column. Does anyone know of a way I can make this code work on IE 7/8?

  • A submenu (`ToolStripMenuItem`) does not show automatically.

    - by czuk
    I have encountered strange problem with a three-level context menu. In some situation the sub menu does not show automatically. I have following structure of the menu: * AAA - level 1 * BBB - level 1 * CCC - level 2 * xxx - level 3 * yyy - level 3 * DDD - level 2 * zzz - level 3 * vvv - level 3 I start from a menu with two option AAA and BBB. After I move the cursor over BBB the second-level menu appears with two other options CCC and DDD. So far OK. Now, when I quickly move the cursor over DDD the third-level sub menu does not show up, but when I move the cursor back to CCC the sub menu shows up, and when I go back to DDD then the sub menu also shows. Why it does not show at first time? Have you ever encountered such a problem? I fixed the problem with MouseEnter and MouseLeave events, but I still wonder why it does not work properly without the events.

  • second sorting with php usort

    - by bluedaniel
    So Ive got a pretty big array of data and need to sort them by two criteria. There is variable $data['important'] and $data['basic']. They are simple numbers and I am using uasort to sort $data firstly by important and then by basic. So Important | Basic 10 | 8 9 | 9 9 | 7 7 | 9 The usort function is a simple public function sort_by_important($a, $b) { if ($a[important] > $b[important]) { return -1; } elseif ($b[important] > $a[important]) { return 1; } else { return 0; } } How can I re-sort the array to the second variable and keep the Important ordering? Thanks everyone. EDIT How about adding a third sorting option after this even? So Important Basic Less

  • Can I use WCF on Visual Studio 2005?

    - by Hemant
    I am about to start a project which consumes third party web services. Because of a legacy system, I am told that I can only use Visual Studio 2005/.NET 2.0. (Though I would have preferred Visual Studio 2008 on .NET 3.5) My understanding is that WCF was released with .NET 3.0. So is there any possibility to use WCF on Visual Studio 2005 by using just the WCF assemblies of .NET 3.0? I will then try to convince them that it is just like using external framework which doesn't disturb anything.

  • How To Configure Query Cacheing in EclipseLink

    - by rustyshelf
    I have a collection of states, that I want to cache for the life of the application, preferably after it is called for the first time. I'm using EclipseLink as my persistence provider. In my EJB3 entity I have the following code: @Cache @NamedQueries({ @NamedQuery( name = "State.findAll", query = "SELECT s FROM State s", hints = { @QueryHint(name=QueryHints.CACHE_USAGE, value=CacheUsage.CheckCacheThenDatabase), @QueryHint(name=QueryHints.READ_ONLY, value=HintValues.TRUE) } ) }) This doesn't seem to do anything though, if I monitor the SQL queries going to MySQL it still does a select each time my Session Bean uses this NamedQuery. What is the correct way to configure this query so that it is only ever read once from the database, preferably across all sessions? Edit: I am calling the query like this: Query query = em.createNamedQuery("State.findAll"); List<State> states = query.getResultList();

  • SQL Server Reporting Services Bar Chart

    - by Avitus
    I am trying to create horizontal bar chart to look like a pill chart. I would like to take a either a stacked bar chart or a 100% stacked bar chart and put rounded ends onto this chart. I would only be using 1 row within the chart. One idea I had was just putting rounded images on either end of the chart to accomplish this but I'm not sure that this will give the smooth feel of a single pill. Does anyone have a good suggestion? I am not tied to the idea of using a chart object. But I would prefer to stay away from third party components that need to be purchased.

  • Why this java application print "true"?

    - by user292084
    This is my first Class Hello.java public class Hello { String name = ""; } This is my second Class Test1.java public class Test1 { public static void main(String[] args) { Hello h = new Hello(); Test1 t = new Test1(); t.build(h); System.out.println((h.name)); } void build(Hello h){ h.name = "me"; } } When I run Test1.java, it prints "me". I think I understand, because of "reference transfer". This is my third Class Test2.java public class Test2 { public static void main(String[] args) { Hello h = null; Test2 t = new Test2(); t.build(h); System.out.println(((h == null))); } void build(Hello h){ h = new Hello(); } } When I run Test2.java, it prints "true", why ? Is it "reference transfer" no longer? I am confused.

  • Problem indexing files in Solr on Ubuntu

    - by nik
    Hi, What I want to do is index some documents in Solr and know how it works. I have installed Solr and Tomcat and can see Solr Admin UI at localhost:8080/ solr/ admin/ Now, I want to add some documents to the index, may I know how to proceed further? I find very less documentation on Internet regarding this. In the tutorial http://lucene.apache.org/solr/tutorial.html#Indexing+Data they asked to run java -jar post.jar solr.xml monitor.xml command but after running that I get connection refused error as it is jetty. After installing jetty I tried telnet: I get "Connection refused" error I am not able to understand what the problem is.

  • Dynamic form creation from XSD in ASP.NET

    - by CitadelCSAlum
    I know there is a lot of documentation on the internet as far as XSD to forms, but I have not been able to come across one that is straight forward enough for my situation. I am working with a WCF web service that is going to fetch and .xsd xml schema, and must return the HTML of a form based on the .xsd xml schema. Is there any third party tools that can help out with this, if so what are they? If not, do you have any suggestions,better methods,etc for how this can be done?

  • Can I safely move my project to .NET 4.0?

    - by Decker
    I've migrated my project to VS2010 but have not yet targeted .NET 4.0. It's currently targeting 3.5 SP1 (and CLR 2). The project relies on several third party components -- mostly open source -- that were presumably built against the 2.0 CLR. Can I simply retarget my project to the 4.0 runtime? Or do I have to get new versions of all the referenced assemblies on which it depends? I've read a little about the new in-process side-by-side feature of .NET 4.0, but I don't think it applies here (the example I read was about two different .NET plug ins to an office application). My situation is different. My solution directly references assemblies and I wouldn't think side-by-side applies -- unless I don't understand its purpose. TIA

  • How to buffer stdout in memory and write it from a dedicated thread

    - by NickB
    I have a C application with many worker threads. It is essential that these do not block so where the worker threads need to write to a file on disk, I have them write to a circular buffer in memory, and then have a dedicated thread for writing that buffer to disk. The worker threads do not block any more. The dedicated thread can safely block while writing to disk without affecting the worker threads (it does not hold a lock while writing to disk). My memory buffer is tuned to be sufficiently large that the writer thread can keep up. This all works great. My question is, how do I implement something similar for stdout? I could macro printf() to write into a memory buffer, but I don't have control over all the code that might write to stdout (some of it is in third-party libraries). Thoughts? NickB

  • timeline charts with rich ui

    - by Karthick R
    hi all, I have a requirement to come up with a time line chart and a few more controls on a single page[with rich ui]. I have short listed Flex, JSF[apache trinidad], html5, gwt these technologies. None of them provide timeline charts on their own. I am looking at other options such as using third party libraries. The chart should have drill down capabilities as well. Let me know if there is any specific technology that I should try. regards

  • SQL: Join Parent - Child tables

    - by pray4Mojo
    I'm building a simple review website application and need some help with SQL Query. There are 3 tables (Topics, Comments, Users). I need a SQL query to select the data from all 3 tables. The 'Topics' table is the parent and the 'Comments' table contains the child records (anywhere from zero to 100 records per parent. The third table 'Users' contains the user information for all users. Here are the fields for the 3 tables: Topics (topicID, strTopic, userID) Comments (commentID, topicID, strComment, userID) Users (userID, userName) I tried: SELECT * FROM Topics Inner Join Comments ON Topics.topicID = Comments.topicID Inner Join Users ON Topics.userID = Users.userID But this does not work correctly because there are multiple topics and the User info is not joined to the Comments table. Any help would be appreciated.

  • SQLITE (C/C++interface) - How to commit a transaction

    - by AJ
    I am using sqlite c/c++ interface. Now here is my scenario - I have 3 tables (related tables) say A, B, C. Now, there is a function called Set, which get some inputs and based on the inputs inserts rows into these three tables. (sometimes it can be an update in one of the tables) Now I need two things. One, i dont want autocommit feature. Basically I would like to commit after every 1000 calls to Set function Secondly, within the set function itself, if i find that after inserting into two tables, the third insert fails, then i have to revert, those particular changes in that Set function call. Now i dont see any sqlite3_commit function exposed. I only see a function called sqlite3_commit_hook() which is slightly diff in documentation. Are there any function exposed for this purpose? or What is the way to achieve this behaviour? Can you help me with the best approach of doing this. Regards, Arjun

  • Tables relationship in Cakephp

    - by kwokwai
    Hi all, I am new to Models structure in Cakephp. A few weeks ago I came across a tutorial in which the author got three tables in Database: Table A: {ID, Description, IsActive} Table B: {ID, TableA_ID, Description, CreationDate, ModifiedDate} Table A_B: {ID, TableA_ID, TableB_ID} The author of the tutorial said that the third table (Table A_B) is needed to run in CakePHP. I don't understand. Is there any specific documentation in CakePHP that I can refer to? I know there is a CookBook in Cakephp web site, but I couldn't find the relevant infromation.

  • Produce a script to hit Google once a day and log our position in the results?

    - by hawbsl
    The need has arisen within our organisation to monitor (on a daily basis) where our site appears (both organic and PPC) on the page 1 of Google. Also where a key competitor appears. For certain key words. In the immediate short term a colleague is doing this by hitting Google manually and jotting down the results. Yep. It occurs to us we can write a script (e.g. using C#) to do this. I know Analytics will tell us an awful lot but it doesn't note the competitor's position, plus I don't think it has other data we want. Question is, is there an existing basic tool which does this (for free, I guess)? And if we write it ourselves, where to start and are there obvious pitfalls to avoid (for example can Google detect and block automated requests?)

  • UINavigation controller problem

    - by VansFannel
    Hello. I'm developing an iPhone application and I'm trying to do this: I want an application with tree views. The view shown first, doesn't have a navigation bar. If the user tap on a button, I need to open the second view with a navigation bar and a table view. The user can also add new items to the table view. If the user do so, the application will show the third view where the user can add fields (this view has also a navigation bar). It may seem simple, but for me it is not. I don't know how to use the UINavigationController and have not found yet a similar example for what I do (paragraph translated by google). UPDATE I don't know how where to put UINavigationController. How can I do that? Can I use a UIViewController to call a UINavigationController? Thank you.

  • MySQL count problem

    - by Skuja
    I have 3 tables users(id,name),groups(id,name) and users_groups(user_id,group_id). users and groups have many to many relationship, so the third one is for storing users and groups relations. I would like to select all the data from groups with user count in each group. So far I came up with this: SELECT groups.*, COUNT(users_groups.user_id) AS user_count FROM groups LEFT JOIN users_groups ON users_groups.group_id = groups.id The problem is that query result is not returning any of groups which has no users (users_groups doesnt have any records with group_id of those groups). How should I create my query to select all the groups and they user count, or user count as 0 if there are no users for that group?

If possible please provide some resource as to how to configure it for android.

  • In ASP.NET, can too many CacheDependency instances affect scalability?

    - by frankadelic
    I am building an ASP.NET application. Within each ASPX page, we are outputting inline snippets of HTML that are pulled from static text files. Similar to the example shown here: http://www.dotnetcurry.com/ShowArticle.aspx?ID=331 As in the article, we store the contents of the files in HttpRuntime.Cache with a CacheDependency pointing to the included file. For each cached file, the operating system needs to monitor a file for changes. Is this going to be a potential scalability problem? Does Windows 2008 have a maximum number of file change monitors?
