  • jQuery: Get height of hidden element in jQuery 1.4.2

    - by mkoryak
    I need to get height of an element that is within a div that is hidden. Right now I show the div, get the height, and hide the parent div. This seems a bit silly. Is there a better way? I'm using jQuery 1.4.2: $select.show(); optionHeight = $firstOption.height(); //we can only get height if its visible $select.hide();

  • Is there a way in PHP to keep a file open and process each line and subsequent lines?

    - by Chris Denman
    I want to write a php script that keeps the apache_log file open and "listen" to the log and deal with each log entry as it happens. I'm thinking that I need to open a file, get the number of lines, then do this again in a loop - and when the size is different, read the new lines and process them. Am I barking up the wrong tree, or is there a silly easy solution that I have missed? Chris

  • Creating a java library

    - by Albinoswordfish
    This may be a silly question, but right now I have a rather large class that I want to use as a library. Where somebody can simply add this jar file to their classpath. And then simply do an import statement at the top, then he or she can start using this class. Is there anything special I need to do or can I simply just use the jar file built?

  • SQL Server 2008 - A clever way to fill a column with rising integers

    - by cc0
    This is a really silly question probably, I'm working on a database and what I want to do is create a table with an ID (auto increment) and another column: "Number" (I realize it sounds useless but bare with me here please), and I need to fill this "Number" column with values from 1 to 180, each time adding 1 to the previous. What would be a clever "automatic" way of doing that?

  • String.Format an integer to use 1000's separator without leading 0 for small integers

    - by Kragen
    Silly question, I want to format an integer so that it appears with the 1000's separator (,), but also without decimal places and without a leading 0. My attempts so far have been: String.Format("{0} {1}", 5, 5000); // 5 5000 String.Format("{0:n} {1:n}", 5, 5000); // 5.00 5,000.00 String.Format("{0:0,0} {1:0,0}", 5, 5000); // 05 5,000 The output I'm after is: 5 5,000 Is there something obvious that I'm missing?

  • Extraneous Library Linkage

    - by gmatt
    I have a question which may be somewhat silly because I'm pretty sure I may know the answer already. Suppose you have static library A, and dynamic shared object library B and your program C under linux. Suppose that library A calls functions from library B and your program calls functions from library A. Now suppose that all functions that C calls in A make no use of functions in B. To compile C will it be enough to link just A and omit B and furthermore can your program C be run on a system without library B installed?

  • Do I need to check capacity before adding an element to a vector in c++ ?

    - by Cassie
    Hi dear all, I am a newbie to c++ STL vectors so sorry for silly questions in advence. :) In my program, I have a vector which needs to store unknown number of elements. Do I have to check if the vector has achieved its max_size before adding an new element to it ? Will a c++ compiler throw an exception automatically when a program tries to add elements to a full vector ? Thank you very much, Cassie

  • Variable Context Question

    - by Soo
    In the following code snippet, if I leave out the line of code that is surrounded by the /////'s, I get an error that reads: "Use of unassigned local variable CurrentDate". It seems a bit silly for me to just give CurrentDate an arbitrary value, is there a better way around this? DateTime CurrentDate; /////////////////////////// CurrentDate = DateTime.Now; /////////////////////////// if(1==1) { CurrentDate = DateTime.Now.AddDays(1); } if(CurrentDate == DateTime.Now) { ... }

  • Bash sourcing of functions in other languages

    - by ABach
    This is, perhaps, a silly question, but it's something that I've wondered about: is it possible to, say, define a Ruby/Python/Perl/etc. function in some file and then source it in Bash (to make it available anywhere in the current shell)? At the moment, I "source" scripts/functions in other languages by creating a bash alias that executes that script... But I wonder if it's possible for Bash to interpret those other functions directly? Thanks. :)

  • C# inheritance of fields

    - by Emil D
    This is probably a silly question, but here it goes.Imagine you have the following classes: public class C { } public class D : C { //A subclass of C } public class A { C argument; } Now, I want to have a class B, that inherits from A.This class would obviously inherit the "argument" field, but I wish to force the "argument" field in B to be of type D, rather than C.Since D inherits from C this shouldn't create any problems. So, how would achieve this in c# ?

  • Switching main view in WPF

    - by mico
    I know it might be silly, I have just started with WPF. I want to switch to a different view when a user clicks on a control, for example showing a detail page after a click on a list. This view would replace the original. In a web application this would be navigating to a different page. What is the local idiom for that?

  • When to write an iterator?

    - by Jon
    I know this is probably a silly question.. When would I need to write my own iterator? Is it just when designing my own container class? Are there any other times when I would want to create my own iterator? Examples would be appropriated. -Jon

  • Generate SQL script to insert XML from files, using Powershell

    - by Jeff Meatball Yang
    I have a bunch of (50+) XML files in a directory that I would like to insert into a SQL server 2008 table. How can I create a SQL script from the command prompt or Powershell that will let me insert the files into a simple table with the following schema: XMLDataFiles ( xmlFileName varchar(255) , content xml ) All I need is for something to generate a script with a bunch of insert statements. Right now, I'm contemplating writing a silly little .NET console app to write the SQL script. Thanks.
