  • Is a selector like *+* safe to use?

    - by mcmullins
    I recently came across this CSS selector while trying to find a way to easily space out major blog elements such as paragraphs and images. An example of its use would be something like this: .post *+* {margin-top: 15px;} /* or... */ .post > *+* {margin-top: 15px;} /* if you don't want the margin to apply to nested elements */ At first glance, it seemed pretty useful. So my question is: What downsides are there to using these selectors? Specifically: What's the browser support like for this? Are there any cases you wouldn't want an even margin spacing between elements in an article and if not, is it easier to declare this first and then overwrite or simply declare each element individually? Does this have performance issues since you're selecting everything twice?

  • How do I release an object allocated in a different AutoReleasePool ?

    - by ajcaruana
    Hi, I have a problem with the memory management in Objective-C. Say I have a method that allocates an object and stores the reference to this object as a member of the class. If I run through the same function a second time, I need to release this first object before creating a new one to replace it. Supposing that the first line of the function is: NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; This means that a different auto-release pool will be in place. The code to allocate the object is as follows: if (m_object != nil) [m_object release]; m_object = [[MyClass alloc] init]; [m_object retain]; The problem is that the program crashes when running the last line of the method: [pool release]; What am I doing wrong ? How can I fix this ? Regards Alan

  • Concatenating a Text in front of Individual Database Records with Tcl

    - by DFM
    Hello: In short, currently I am using the following code to pull records from multiple tables in a Sqlite Db and insert them in a single combobox ($SearchBar): set SrchVals1 [db eval {SELECT DISTINCT Stitle From Subcontract Order By Stitle ASC}] set SrchVals2 [db eval {... set SrchVals3 ... set SrchValsALL [concat $SrchVals1 $SrchVals2 $SrchVals3] $SearchBar configure -value $SrchValsAll For the variable "SrchVals1", I am trying to figure out a way to concatenate the text "Sub: " to each individual record in SrchVals1. For example, if SrchVals1 shows the following records in the combobox: First Title Second Title Third Title I would like to concatenate so that the records in the combobox look like this: Sub: First Title Sub: Second Title Sub: Third Title I understand that I might have to use a foreach statement; however, I am having no luck writing one that adds "Sub: " in front of each record, as opposed to one. This seems like something that should be pretty easy, but I cannot seem to figure it out. Does anyone know how I can achieve these results? Thank you, DFM

  • Do I have to duplicate this function? - jQuery

    - by Josh
    I'm using this function to create an transparent overlay of information over the current div for a web-based mobile app. Background: using jQTouch, so I have separate divs, not individual pages loading new. $(document).ready(function() { $('.infoBtn').click(function() { $('#overlay').toggleFade(400); return false; }); }); Understanding that JS will run sequentially when i click the button on the first div the function works fine. When I go to the next div if I click the same button nothing "happens" when this div is displayed, but if i go back to the first div it has actually triggered it on this page. So I logically duplicated the function and changed the CSS selector names and it works for both. But do I have to do this for each use? Is there a way to use the same selectors, but load the different content in each variation?

  • JQuery post to php

    - by RussP
    Why is it that I can never get JQuery serialize to work properly. I guess I must be missing something. I can serialize a form data and it shows in an alert: var forminfo = $j('#frmuserinfo').serialize(); alert(forminfo); I then post to my PHP page thus: $j.ajax({ type: "POST", url: "cv-user-process.php", data: "forminfo="+forminfo, cache: false, complete: function(data) { } }); But WHENEVER (not the first time) I try to insert/update the data in the DB I only ever get 1 varaible passed: Here is my PHP script: $testit = mysql_query("UPDATE cv_usersmeta SET inputtest='".$_POST['forminfo']."' WHERE user='X'"); the data passed only ever gets the first variable. why? I think it is more the way I deal with the php but it drives me nuts and always takes me far too long to find where I am going wrong.

  • What was the thinking behind the development of Object Oriented Programming?

    - by leeand00
    I've got some real nay-sayers on my hands here, and I'm trying to give them the reason why OOP was developed in the first place. I realize that OOP is not perfect for all problems and situations, but it was developed for a reason... My guess would be, that a few of those reasons would be: Maintainability Re-usability Document-ability Abstraction of Complex Technologies Dynamic Extension at Runtime... Probably some things that I'm not even aware of yet... But I really don't have much to back this up, and I was wondering why OOP was developed in the first place, and it's history. What were the people who developed OOP trying to accomplish? What led them to develop OOP?

  • How to Delete Duplicate Rows in SQL 2000?

    - by Mikecancook
    I thought I had this figured out but it turns out I'm just deleting the first record. The following returns the duplicate rows. All have a count of 2. I just want to delete the first one for each duplicate record. select scorestudentid, scoreadvisor, scorecorrect, count(*) from scores where scoretestid = 3284 group by scorestudentid, scoreadvisor, scorecorrect having count(scorestudentid) > 1 Which returns: scorestudentid scoreadvisor scorecorrect no column name 13033719 28059 3.0 2 13033777 28086 3.0 2 13033826 28147 3.0 2 13033960 28023 3.0 2 So I put this together thinking it would work: set rowcount 1 delete from scores where scoretestid = 3284 and scorestudentid in ( select scorestudentid from scores where scoretestid = 3284 group by scorestudentid having count(scorestudentid) > 1) It really seems like it should be a simple concept but I'm not getting it.

  • Why doesn't C++ have a garbage collector?

    - by Jason Baker
    I'm not asking this question because of the merits of garbage collection first of all. My main reason for asking this is that I do know that Bjarne Stroustrup has said that C++ will have a garbage collector at some point in time. With that said, why hasn't it been added? There are already some garbage collectors for C++. Is this just one of those "easier said than done" type things? Or are there other reasons it hasn't been added (and won't be added in C++0x)? Cross links: Garbage collectors for C++ EDIT: Just to clarify, I understand the reasons why C++ didn't have a garbage collector when it was first created. I'm wondering why the collector can't be added in.

  • SQL Server (TSQL) - Is it possible to EXEC statements in parallel?

    - by Investor5555
    SQL Server 2008 R2 Here is a simplified example: EXECUTE sp_executesql N'PRINT ''1st '' + convert(varchar, getdate(), 126) WAITFOR DELAY ''000:00:10''' EXECUTE sp_executesql N'PRINT ''2nd '' + convert(varchar, getdate(), 126)' The first statement will print the date and delay 10 seconds before proceeding. The second statement should print immediately. The way T-SQL works, the 2nd statement won't be evaluated until the first completes. If I copy and paste it to a new query window, it will execute immediately. The issue is that I have other, more complex things going on, with variables that need to be passed to both procedures. What I am trying to do is: Get a record Lock it for a period of time while it is locked, execute some other statements against this record and the table itself Perhaps there is a way to dynamically create a couple of jobs? Anyway, I am looking for a simple way to do this without having to manually PRINT statements and copy/paste to another session. Is there a way to EXEC without wait / in parallel?

  • I had inserted a jQuery tab in my site. It was working fine till sometime ago. Suddenly it stopped w

    - by vr3690
    Hello, I had inserted two jQuery tabs on my site. One div container had the id - tabs and another had the id tabs-for-views. Both of them were working fine till sometime ago, until i made some changes. I don't remember what the exact changes were.. Right now, the first tab uses the jQuery UI theme I am using. As in, I can see the tab navigation and content panels - but on clicking the tabs nothing happens. But the second (tabs-for-views) is not even converted to proper tabs format. I am using the Drupal CMS for this site. the tabs can be found on this page: http://betterclassofleaders.co.cc/whackk/ this is the jquery ui css file i am using: (insert first link)sites/default/themes/whack_custom/jquery-ui-1.7.2.custom.css

  • VBA for filtering columns

    - by Ampi Severe
    I have a big database-like sheet, first row contains headers. I would like a subset of rows of this table based on column values. Two issues: 1) VBA-wise I would like to loop through the columns, when the values for all necessary columns all match, copy the entire row into a new sheet. 2) The subset of rows is based on a list. This should be the first column to be looped through. For example I want all rows where the value in column A is equal to one of the values in my list. Is there any possibility to autofilter strings based on a list (column) of strings? EDIT Thanks to @Doug Glancy the autofiltering works now, so I've removed my (horrible) code and issue 1 is solved.

  • Edit Mode Delete Spinner Icon for Specific TableView Rows

    - by Michael Bordelon
    I have a grouped tableview. Each section has three rows. I need to be able to delete one section at a time. Using the standard edit mode, I can make it work. However, the delete icon shows up to the left of each cell, not just the first row in each section. Is there a way to suppress the little spinner icon for all rows except the first? I am hoping there is an easy way to do this without subclassing. Thanks for your help. Here is a screenshot to help visualize it: http://picasaweb.google.com/lh/photo/ll-EJY5ACw7oqHH1xKBQ8w?feat=directlink

  • WPF C#: Starting crash due to client 'Region and Language' settings

    - by FrieK
    Hi, I'm working on a WPF C# application, and it seems to crash with a few random people. So eventually I found out it was the 'Region and Language' settings that was responsible. For example, if I were to set my Format to English (United States) it will work, if I set it to Swedish (Sweden) it will crash from the start. When I test this in Visual Studio 2010 it gives error 'TypeInitializationException'. More precisely it does it here (it doesn't get passed the InitializeComponent() void): private void RadioButton_Checked(object sender, RoutedEventArgs e) { Info.SortOrder = SortBy.Rank; } It claims the error at the first line, which is just setting an enum value to a variable. I guess it's just doing it there because it's the first thing it makes, or something. Anyone has any idea how to fix this? I've searched around but can't seem to find out how :( Any help is much appreciated! Thanks

  • Vector.erase(Iterator) causes bad memory access

    - by xon1c
    Hi, I am trying to do a Z-Index reordering of videoObjects stored in a vector. The plan is to identify the videoObject which is going to be put on the first position of the vector, erase it and then insert it at the first position. Unfortunately the erase() function always causes bad memory access. Here is my code: testApp.h: vector<videoObject> videoObjects; vector<videoObject>::iterator itVid; testApp.cpp: // Get the videoObject which relates to the user event for(itVid = videoObjects.begin(); itVid != videoObjects.end(); ++itVid){ if(videoObjects.at(itVid - videoObjects.begin()).isInside(ofPoint(tcur.getX(), tcur.getY()))){ videoObjects.erase(itVid); } } This should be so simple but I just don't see where I'm taking the wrong turn. Thx, xonic

  • How to make sure the value is reset in foreach loop in PHP

    - by kwokwai
    Hi all, I was writing a simple PHP page and a few foreach loops were used. Here are the scripts: $arrs = array("a", "b", "c"); foreach ($arrs as $arr) { if(substr($arr,0,1)=="b") { echo "This is b"; } } // ends of first foreach loop and I didn't use ifelse here And when this foreach ends, I wrote another foreach loop in which all the values in the foreach loop was the same as previous foreach. foreach ($arrs as $arr) { if(substr($arr,0,1)=="c") { echo "This is c"; } } I am not sure if it is a good practice to have two foreach loops with same values and keys. Will the values get overwritten in the first foreach loop?

  • Laying out JPanels to make a simple GUI

  • How do I arbitrarily reorder lines in a text file using a Unix shell?

    - by Tim Bellis
    I've got a text file with an arbitrary number of lines, e.g.: one line some other line an additional line one more here I'd like to write a script to reorder those lines based on a given order. e.g. An input of 2 1 3 4 would swap the first and second lines. An input of 3 1 2 4 would put the 3rd line first, the 1st line second, the 2nd line third and keep the 4th line fourth. I could hack something together, but I'm wondering if there's an elegant solution? I can use either bash or ksh.

  • Efficient bitshifting an array of int?

    - by nn
    Hi, To be on the same page, let's assume sizeof(int)=4 and sizeof(long)=8. Given an array of integers, what would be an efficient method to bitshift the array to either the left or right? I am contemplating an auxiliary variable such as a long, that will compute the bitshift for the first pair of elements (index 0 and 1) and set the first element (0). Continuing in this fashion the bitshift for elements (index 1 and 2) will be computer, and then index 1 will be set. I think this is actually a fairly efficient method, but there are drawbacks. I cannot bitshift greater than 32 bits. I think using multiple auxiliary variables would work, but I'm envisioning recursion somewhere along the line.
