• Data confusion - Selecting data in one DataGridView based on selection in another

  - by Logan Young

  This probably isn't the best way to do what I want, but I can't think of anything else to try... NB: I'm using Visual Basic.NET My form has 2 DataGridView controls. One of these is bound to a DataSet, the other isn't visible - at least not until the user selects a uniqueidentifier cell in the 1st grid. When the user makes this selection, the 2nd grid will become visible and display the row from another with the same id as the one selected in the 1st grid. So, basically, I want to dynamically display data in one grid based on user selection in another grid. My code looks like this so far... Private Sub RulesGrid_CellClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles RulesGrid.CellClick Try FlagsGrid.Visible = True ''// MsgBox(RulesGrid.CurrentCell.Value.ToString()) Dim sql As String = "SELECT * FROM ctblMKA_Status_Flags " + _ "WHERE intStatusID = '" & RulesGrid.CurrentCell.Value & "'" DSFlags = GetDS(sql) DSFlags.DataSetName = "FlagsDataSet" FlagsGrid.DataSource = DSFlags ProgressBar.Visible = False Catch ex As Exception MsgBox(ex.ToString) End Try End Sub I feel like I'm missing something here... Any ideas anyone?

• Returning objects in php

  - by user220201

  I see similar questions asked but I seem to have problem with more basic stuff than were asked. How to declare a variable in php? My specific problem is I have a function that reads a DB table and returns the record (only one) as an object. class User{ public $uid; public $name; public $status; } function GetUserInfo($uid) { // Query DB $userObj = new User(); // convert the result into the User object. var_dump($userObj); return $userObj; } // In another file I call the above function. .... $newuser = GetUserInfo($uid); var_dump($newuser); What is the problem here, I cannot understand. Essentially the var_dump() in the function GetUserInfo() works fine. The var_dump() outside after the call to GetUserInfo() does not work. Thanks for any help. S

• Global name not defined error in Django/Python trying to set foreignkey

  - by Mark

  Summary: I define a method createPage within a file called PageTree.py that takes a Source model object and a string. The method tries to generate a Page model object. It tries to set the Page model object's foreignkey to refer to the Source model object which was passed in. This throws a NameError exception! I'm trying to represent a website which is structured like a tree. I define the Django models Page and Source, Page representing a node on the tree and Source representing the contents of the page. (You can probably skip over these, this is a basic tree implementation using doubly linked nodes). class Page(models.Model): name = models.CharField(max_length=50) parent = models.ForeignKey("self", related_name="children", null=True); firstChild = models.ForeignKey("self", related_name="origin", null=True); nextSibling = models.ForeignKey("self", related_name="prevSibling", null=True); previousSibling = models.ForeignKey("self", related_name="nxtSibling", null=True); source = models.ForeignKey("Source"); class Source(models.Model): #A source that is non dynamic will be refered to as a static source #Dynamic sources contain locations that are names of functions #Static sources contain locations that are places on disk name = models.CharField(primary_key=True, max_length=50) isDynamic = models.BooleanField() location = models.CharField(max_length=100); I've coded a python program called PageTree.py which allows me to request nodes from the database and manipulate the structure of the tree. Here is the trouble making method: def createPage(pageSource, pageName): page = Page() page.source = pageSource page.name = pageName page.save() return page I'm running this program in a shell through manage.py in Windows 7 manage.py shell from mysite.PageManager.models import Page, Source from mysite.PageManager.PageTree import * ... create someSource = Source(), populate the fields, and save it ... createPage(someSource, "test") ... NameError: global name 'source' is not defined When I type in the function definition for createPage into the shell by hand, the call works without error. This is driving me bonkers and help is appreciated.

• Console Application Structure

  - by Paul Fox

  I've written several .Net Console Applications over the past 6 months and we have many more throughout different projects in our organization. I generally stick to the same standard format/structure for my Console Applications. Unfortunately, many of our console applications do not. I have been looking into ways of standardizing the structure of these Console Applications. I would also like to provide a framework for the basic structure of a Console Application and provide easy access to standard ways of handling things such as argument passing, logging, etc. Can anyone suggest Best Practices for addressing these concerns? I have been reading this MSDN article on Console Applications in .Net which suggests a Design Pattern for Console Apps. The example uses a Template Method pattern to handle some of the concerns I listed earlier. Two negatives of using this approach are listed in the article. Ending up with twice as many classes Having many simple, similar classes Can anyone suggest better, or more standard, ways of handling this? What about listing additional negatives with this approach?

• A data structure based on the R-Tree: creating new child nodes when a node is full, but what if I ha

  - by Tom

  I realize my title is not very clear, but I am having trouble thinking of a better one. If anyone wants to correct it, please do. I'm developing a data structure for my 2 dimensional game with an infinite universe. The data structure is based on a simple (!) node/leaf system, like the R-Tree. This is the basic concept: you set howmany childs you want a node (a container) to have maximum. If you want to add a leaf, but the node the leaf should be in is full, then it will create a new set of nodes within this node and move all current leafs to their new (more exact) node. This way, very populated areas will have a lot more subdivisions than a very big but rarely visited area. This works for normal objects. The only problem arises when I have more than maxChildsPerNode objects with the exact same X,Y location: because the node is full, it will create more exact subnodes, but the old leafs will all be put in the exact same node again because they have the exact same position -- resulting in an infinite loop of creating more nodes and more nodes. So, what should I do when I want to add more leafs than maxChildsPerNode with the exact same position to my tree? PS. if I failed to explain my problem, please tell me, so I can try to improve the explanation.

• Is Domain Anaemia appropriate in a Service Oriented Architecture?

  - by Stimul8d

  I want to be clear on this. When I say domain anaemia, I mean intentional domain anaemia, not accidental. In a world where most of our business logic is hidden away behind a bunch of services, is a full domain model really necessary? This is the question I've had to ask myself recently since working on a project where the "domain" model is in reality a persistence model; none of the domain objects contain any methods and this is a very intentional decision. Initially, I shuddered when I saw a library full of what are essentially type-safe data containers but after some thought it struck me that this particular system doesn't do much but basic CRUD operations, so maybe in this case this is a good choice. My problem I guess is that my experience so far has been very much focussed on a rich domain model so it threw me a little. The remainder of the domain logic is hidden away in a group of helpers, facades and factories which live in a separate assembly. I'm keen to hear what people's thoughts are on this. Obviously, the considerations for reuse of these classes are much simpler but is really that great a benefit?

• better understanding of getline() and cin

  - by numerical25

  Trying to get some basic understanding of console functionalities. I am having issues so consider the following... #include "stdafx.h" #include<iostream> #include<conio.h> using namespace std; /* This is a template Project */ void MultiplicationTable(int x); int main() { int value = 0; printf("Please enter any number \n\n"); getline(cin, value); MultiplicationTable(value); getchar(); return 0; } I actually based this off code from http://www.cplusplus.com/doc/tutorial/basic_io/ . My IDE is not recognizing getline() so of course when I compile the application. I get an error 'getline': identifier not found Now take a look at this code #include "stdafx.h" #include<iostream> #include<conio.h> using namespace std; /* This is a template Project */ void MultiplicationTable(int x); int main() { int value = 0; printf("Please enter any number \n\n"); cin>>value; MultiplicationTable(value); getchar(); return 0; } When I execute this line of code the console window opens and immediately closes. I think I a missing something about cin. I do know that it delimits spaces but I don't know what else. what should I use for input to make my life easier.

• Rails: creating a model in the new action

  - by Joseph Silvashy

  I have an interesting situation, well it's probably not that unique at all, but I'm not totally sure how to tackle it. I have a model, in this case a recipe and the user navigates to the new path /recipes/new however the situation is that I need to be able to have the user upload images and make associations to that model in the new action, but the model doesn't have an ID yet. So I assume I need to rethink my controller, but I don't want to have redirects and whatnot, how can accomplish this? Here is the basic controller, barebones obviously: ... def new # I should be creating the model first, so it has an ID @recipe = Recipe.new end def create @recipe = Recipe.new(params[:recipe]) if @recipe.save redirect_to @recipe else render 'new' end end ... update Perhaps I can have a column thats like state which could have values like new/incomplete/complete or what-have-you. I'm mostly trying to figure out what would also be most efficient for the DB. It would be nice if I could still have a url that said '/new', instead of it be the edit path with the id, for usability sake, but I'm not sure this can be simply accomplished in the new action of my controller. Thoughts?

• Attempted GCF app for Android

  - by Aaron

  I am new to Android and am trying to create a very basic app that calculates and displays the GCF of two numbers entered by the user. Here is a copy of my GCF.java: package com.example.GCF; import java.util.Arrays; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.EditText; import android.widget.TextView; public class GCF extends Activity { private TextView mAnswer; private EditText mA, mB; private Button ok; private String A, B; private int iA, iB; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); mA = (EditText) findViewById(R.id.entry); mB = (EditText) findViewById(R.id.entry1); ok = (Button) findViewById(R.id.ok); mAnswer = (TextView) findViewById(R.id.answer1); ok.setOnClickListener(new OnClickListener() { public void onClick(View v) { A = mA.getText().toString(); B = mB.getText().toString(); } }); // the String to int conversion happens here iA = Integer.parseInt(A.trim()); iB = Integer.parseInt(B.trim()); while (iA != iB) { int[] nums={ iA, iB, Math.abs(iA-iB) }; Arrays.sort(nums); iA=nums[0]; iB=nums[1]; } updateDisplay(); } private void updateDisplay() { mAnswer.setText( new StringBuilder().append(iA)); } } Any Suggestions?

• Port Java Application to Android

  - by mihirk

  I am not so sure about the question or what I should call what I am trying to achieve. I use a dialer called super sify. Here is the download - http://thegoan.com/supersify/supersify.zip The when extracted it has two files for linux, one is a .jar file which consists of some classes. The application was written in java. The other is a .sh file, which is a shell executable and takes some parameters like username and password and machine id and stuff. I want to port this app to android. What exactly would I have to do. Some more information is the .jar file is named supersify.jar and the .sh file is named ss.sh so here is the code for ss.sh java -jar supersify.jar $* if [ $? -eq 1 ] then read fi Please help me out. This is an open source software.So I am not doing any illegal modifications. I need to port this app to android, so would I have to write the whole thing again or just something else. I know some basic hello world android app development, and I have made an app to add two numbers, I am still on my way to become an android app developer, but I need this app and will learn a lot to make this possible unless it involves rewriting all the java classes. Thank you in advance If you have anymore question I will be glad to answer to them :D.

• Why is a DataViewManager not sorting?

  - by Alarion

  First off, a quick rundown of what the code is doing. I have two tables: Companies and Clients. There is a one to many relationship between Companies and Clients (one company can have many clients). In some processing logic, I have both tables loaded into a DataSet - each are DataTables. I have added a DataRelation to set the relationship, and it works when I use GetChildRows on a record from the Companies table. However, I need to sort the records returned. After googling around some it looks like the DataViewManager is the way to go, and I have examined several basic examples. However, I cannot get my rows sorted. Am I missing something, or am I not using this how it is supposed to be used? Example code: Dim ldvmManager As New DataViewManager(mdsData) ldvmManager.DataViewSettings("Companies").Sort = "comName ASC" ldvmManager.DataViewSettings("Clients").ApplyDefaultSort = False ldvmManager.DataViewSettings("Clients").Sort = "entLastName ASC, entFirstName ASC" For Each mdrCurrentCompany in ldvmManager.DataViewSettings("Companies").Table.Rows Dim ldrClients() as DataRow = mdrCurrentCompany.GetChildRows("CompaniesClients") Next No matter what I do, the first Client returned has a last name that starts with a 'B' and the second has one that starts with a 'A'. From there, the order is all mixed up. If I use my entire data instead of the subset I was using to test with, the first Client returned has a last name that starts with 'J'. It seems like it is still using whatever default sort was being used before I tried to use the DataViewManager. Any ideas?

• LINQ to SQL - Lightweight O/RM?

  - by CoffeeAddict

  I've heard from some that LINQ to SQL is good for lightweight apps. But then I see LINQ to SQL being used for Stackoverflow, and a bunch of other .coms I know (from interviewing with them). Ok, so is this true? for an e-commerce site that's bringing in millions and you're typically only doing basic CRUDs most the time with the exception of an occasional stored proc for something more complex, is LINQ to SQL complete enough and performance-wise good enough or able to be tweaked enough to run happily on an e-commerce site? I've heard that you just need to tweak performance on the DB side when using LINQ to SQL for a better approach. So there are really 2 questions here: 1) Meaning/scope/definition of a "Lightweight" O/RM solution: What the heck does "lightweight" mean when people say LINQ to SQL is a "lightweight O/RM" and is that true??? If this is so lightweight then why do I see a bunch of huge .coms using it? Is it good enough to run major .coms (obviously it looks like it is) and what determines what the context of "lightweight" is...it's such a generic statement. 2) Performance: I'm working on my own .com and researching different O/RMs. I'm not really looking at the Entity Framework (yet), just want to figure out the LINQ to SQL basics here and determine if it will be efficient enough for me. The problem I think is you can't tweak or control the SQL it generates...

• Acessing a wordpress database from an iPhone App.

  - by Code

  Hi guys, I've been asked to create an app that will get data back from a database where the CMS will be Wordpress. I've never used a CMS so I'm trying to get a (overview)picture in my head of how it could all work and what each of the components would be. And what a CMS actually brings to the party. Creating the app itself is pretty clear. I've done a few already. I've made a database before and shouldnt cause a problem. But what is going to be in the middle between the app and the database? Part A: I'm guessing iphone apps typically would call some php file that's hosted on the server? The php then would make a call to the database and return the data somehow, maybe as xml. But this is really basic and wouldnt require a CMS. Just a database and a phpfile, or am I wrong? Part B: If i wanted to run a check on the database every minute to see if any of the data in database was no longer valid and remove it if needed, that would require somekind of program running on the server. So that program would be Wordpress, since it is managing the content, so a content management system is actually needed and is for these kind of taskes. Am i understanding the role of CMS? Many Thanks, -Code

• Choropleth mapping issue in R

  - by chasec

  I am trying to follow the tutorial described here: http://www.thisisthegreenroom.com/2009/choropleths-in-r/ The below code executes, but it is either not matching my dataset with the maps_counties data properly, or it isn't plotting it in the order I would expect. For example, the resulting areas for the greater NYC area show no density while random counties in PA show the highest density. The general format of my data table is: county state count fairfield connecticut 17 hartford connecticut 6 litchfield connecticut 3 new haven connecticut 12 ... ... westchester new york 70 yates new york 1 luzerne pennsylvania 1 Note this data is in order by state and then county and includes data for CT, NJ, NY, & PA. First, I read in my data set: library(maps) library(RColorBrewer) d <- read.table("gissum.txt", sep="\t", header=TRUE) #Concatenate state and county info to match maps library d$stcon <- paste(d$state, d$county, sep=",") #Color bins colors = brewer.pal(5, "PuBu") d$colorBuckets <- as.factor(as.numeric(cut(d$count,c(0,10,20,30,40,50,300)))) Here is my matching mapnames <- map("county",plot=FALSE)[4]$names colorsmatched <- d$colorBuckets [na.omit(match(mapnames ,d$stcon))] Plotting: map("county" ,c("new york","new jersey", "connecticut", "pennsylvania") ,col = colors[d$colorBuckets[na.omit(match(mapnames ,d$stcon))]] ,fill = TRUE ,resolution = 0 ,lty = 0 ,lwd= 0.5 ) map("state" ,c("new york","new jersey", "connecticut", "pennsylvania") ,col = "black" ,fill=FALSE ,add=TRUE ,lty=1 ,lwd=2 ) map("county" ,c("new york","new jersey", "connecticut", "pennsylvania") ,col = "black" ,fill=FALSE ,add=TRUE , lty=1 , lwd=.5 ) title(main="Respondent Home ZIP Codes by County") I am sure I am missing something basic re: the order in which the maps function plots items - but I can't seem to figure it out. Thanks for the help. Please let me know if you need any more information.

• Should I go to school and get my degree in computer science?

  - by ryan

  I'll try and keep this short and simple. I've always enjoyed programming and I've been doing it since high school. Right after I graduated from high school (2002), I opted to skip college because I was offered a software engineer position. I quit after a couple of years later to team up on various startup companies. However, most of them did not launch as well as expected. But it honestly did not matter to me because I've learned so much from that experience. So fast forwarding to today, now turned 25, I need a job due to this tough economic climate. Looking on Craigslist, a lot of the listings require computer science degrees. It's evident now that programming is what I want to do because I seem to never get enough of it. But just the thought of having to push 2 years without attending any real computer class for an Associates at age 25 is very, very discouraging. And the thought of having to learn from basic (Hello WOOOOORRLLLD) just does not seem exciting. I guess I have 3 questions to wrap this up: Should I just suck it up and go back to school while working at McDonalds at age 25? Is there a way where I can just skip all the boring stuff and just get tested with what I know? From your experience, how many jobs use computer science degrees as prerequisites? Or am I screwed and better pray that my next startup will be the next big thing?

• In the meantime, to be or not to be ... productive!

  - by Jan Kuboschek

  I just moved back to Europe from the US after living there for 7 years. Apart from major adjustment issues, I'm currently looking for a job over here. I'm mainly interested in (IT) Consulting and, since these jobs typically require programming knowledge, such as Java, I'm trying to think of something productive to write (perhaps to demo my skills) while I'm waiting for my interviews (starting in two weeks. Folks here are a bit slower than in the US apparently...). I graduated from college about a year and a half ago and have a 4 year degree in international management/economics and about 3/4 of a 2 year degree in computer science finished. I've written my fair share of web software over the years, but nothing concrete that I could show, especially not in Java. Now, I've never had the problem of not having any idea what to write. Basic games I could write, but I'm not sure how well that'll come over when I walk into my interview and say "hey, I was bored. Take a look at my multiplayer space invaders game! Wanna try beating me??". Any thoughts? I browsed SourceForge the other day to find a nice little project to contribute to, but decided that I don't want to commit to someone else's project at this time. Any ideas, perhaps from someone who has been, or currently is, in a similar position would be much appreciated. Oh, and lastly: Instead of developing a program or two to demonstrate my skills, I could spend my time brushing up on UML and Perl. Any suggestions regarding that? Writing a demo vs. learning something new?

• Sync data between a windows desktop app and windows mobile client app

  - by Chris W

  I need to knock up a very quick prototype/proof of concept application to demo to someone within the next couple of days so I've minimal time to research this as fully as I normally would. The set-up is a very simple database application running on a laptop - will only ever be a single user updating a couple of tables so I was thinking of knocking up a basic Win Forms app against SQL Compact. Visual Studio's auto generated data grid edit screens will be fine with a little customisation. The second aspect is to then add a windows mobile client application that can pull data from both tables stored on the laptop, edit some data and insert some extra rows before sending the changes back to the laptop copy of the database. I've not done any WinMo development so what's the best approach for me to look at. Is it easy enough to sync data between the two databases when the WinMo device is connected to the laptop with USB? Most of the samples I've looked at so far seem to be syncing SQL Compact with SQL Standard using IIS which seems a bit overkill. The volumes of data to be synced are so small that I can easily write some manual sync code if it's easy for me to query/update the Compact DB from the laptop application when the device is connected.

• Best way of creating lite and extended version of Git project

  - by Saif Bechan

  I have made a little framework for php. In this project I have the basic functionalities that I use for most of my projects. I have also inserted some sample data so I do not forget how it all works again. I have put the framework under version control using git. Everything works fine now and I want to further build on this. This is my first git project so I do not know which method I should use. Ok the first thing I want to do is creating 2 more versions of the project. As I explained before the version I have now has some sample data inside it. So the first version I want to create is a stripped down version, removing the sample data. I can use this version to create any new project. The second version I want to create is an extended version. This has the lite version, combined with the sample data, plus some more extensions on it. So in the end I have 3 version of the same project, small medium and large. Now what is the best way of doing this. Should I create 3 repositories for this, or can I use just one repository for all the versions.

• Windows Phone 7 applications - Orientation Change

  - by Peter Perhác

  Hello there fellow developers! I am working on a Windows Phone 7 app and I can't figure out what I believe is a simple problem for the more seasoned ones. Say I have a layout consisting of two elements: a ListBox (filled with an abundance of items) and a TextBlock (providing the user with some basic instructions). I want these to be one above the other when the device is in Portrait orientation and I want these to be next to each other when the device orientation changes to Landscape. For the Portrait orientation I am using a Grid layout manager, as it lets me define the rows' heights like so... row 0 Height="2*", row 1 Height="*" Listbox sits in row 0, TextBlock in row 1. Now, what would be really neat is to simple change the RowDefinitions into ColumnDefinitions and reassign the listbox/textblock to the grid's columns instead of rows for when the device switches into Landscape. But that's just my idea. I don't know how to get this done elegantly. Maybe there's a better approach to this? Or maybe this is the correct approach and there is some method built for exactly this purpose? Thank you for your suggestions!

• I want to build a Google-friendly web app, where should I start?

  - by ronii

  I have only very basic experience with HTML/CSS and have quite a bit of experience with testing software and web apps from a consumer perspective. I'd love to launch a web application that plays nicely with Google services, similar to some of the apps you'd find on the Google Apps Marketplace, such as ManyMoon, time to note, Socialwok, etc. I'm a huge Google fan and would like to build something that's well integrated with other Google services. If you were a total beginner and wanted to build a complex app like one of examples above (project management, CRM, etc), where would you start? If you worked your ass off 18 hours a day, 24/7, how fast could you do it? I've dabbled into various languages and development frameworks, and read about which apps are using what languages but it's hard to figure out what would be most beneficial to jump into. Ruby on Rails, PHP, Google Web Toolkit, AppEngine. The list goes on and on. I want to be able to build and launch my own scalable web app. Thanks.

• Calculating collission for a moving circle, without overlapping the boundaries

  - by Robert Vella

  Let's say I have circle bouncing around inside a rectangular area. At some point this circle will collide with one of the surfaces of the rectangle and reflect back. The usual way I'd do this would be to let the circle overlap that boundary and then reflect the velocity vector. The fact that the circle actually overlaps the boundary isn't usually a problem, nor really noticeable at low velocity. At high velocity it becomes quite clear that the circle is doing something it shouldn't. What I'd like to do is to programmitically take reflection into account and place the circle at it's proper position before displaying it on the screen. This means that I have to calculate the point where it hits the boundary between it's current position and it's future position -- rather than calculating it's new position and then checking if it has hit the boundary. This is a little bit more complicated than the usual circle/rectangle collission problem. I have a vague idea of how I should do it -- basically create a bounding rectangle between the current position and the new position, which brings up a slew of problems of it's own (Since the rectangle is rotated according to the direction of the circle's velocity). However, I'm thinking that this is a common problem, and that a common solution already exists. Is there a common solution to this kind of problem? Perhaps some basic theories which I should look into?

• Help me sort programing languages a bit

  - by b-gen-jack-o-neill

  Hi, so I asked here few days ago about C# and its principles. Now, if I may, I have some additional general questions about some languages, becouse for novice like me, it seems a bit confusing. To be exact I want to ask more about language functions capabilities than syntax and so. To be honest, its just these special functions that bothers me and make me so confused. For exmaple, C has its printf(), Pascal has writeln() and so. I know in basic the output in assembler of these funtions would be similiar, every language has more or less its special functions. For console output, for file manipulation, etc. But all these functions are de-facto part of its OS API, so why is for example in C distinguished between C standard library functions and (on Windows) WinAPI functions when even printf() has to use some Windows feature, call some of its function to actually show desired text on console window, becouse the actuall "showing" is done by OS. Where is the line between language functions and system API? Now languages I dont quite understand - Python, Ruby and similiar. To be more specific, I know they are similiar to java and C# in term they are compiled into bytecode. But, I do not unerstand what are its capabilities in term of building GUI applications. I saw tutorial for using Ruby to program GUI applications on Linux and Windows. But isn´t that just some kind of upgrade? I mean fram other tutorials It seemed like these languages was first intended for small scripts than building big applications. I hope you understand why I am confused. If you do, please help me sort it out a bit, I have no one to ask.

• Progressive enhancement of anchor tags to avoid onclick="return false;"

  - by Chris Beck

  Unobtrusive JS suggests that we don't have any onclick attributes in our HTML templates. <a href="/controller/foo/1">View Foo 1</a> A most basic progressive enhancement is to convert an that anchor tag to use XHR to retrieve a DOM fragment. So, I write JS to add an event listener for a."click" then make an XHR to a.href. Alas, the browser still wants to navigate to "/controller/foo". So, I write JS to dynamically inject a.onclick = "return false;". Still unobtrusive (I guess), but now I'm paying the the cost of an extra event handler. To avoid the cost of 2 event listeners, I could shove my function call into the onclick attribute <a href="/controller/foo/1" onclick="myXHRFcn(); return false;"> But that's grodo for all sorts of reasons. To make it more interesting, I might have 100 anchor tags that I want to enhance. A better pattern is a single listener on a parent node that relies on event bubbling. That's cool, but how do I short circuit the browser from navigating to the URL without this on every anchor node? onclick="return false;" Manipulating the href is not an option. It must stay intact so the context menu options to copy or open in new page work as expected.

Here is my HTML /. CSS: <ul id="leftcol"> <li><a class="active" href="#">Company Overview</a></li> <li><a href="#">Why Choose Parker?</a></li> <li><a href="#">Testimonials</a></li> <li><a href="#">Financing Promotions</a></li> <li><a href="#">Licensing & Credentials</a></li> </ul> ul#leftcol{float:left; width:185px; position:relative; z-index:10;} ul#leftcol li{float:right; clear:right; margin-bottom:14px; list-style:none; list-style-image:none; text-align:right; line-height:1.3; } ul#leftcol li a{color:#505050; text-decoration:none; font-size:15px; float:right;} ul#leftcol li a.active,ul#leftcol li a:hover{color:#89b060;} Any ideas?

• Ignore all folders with a certain name in SVN (subversion), how to?

  - by Roeland

  I am fairly new to Subversion and was wondering how exactly to ignore all folders by a specific name. From what I have read, I think I need to use the svn:ignore function, but I have no clue on how to actually do this. Some places mention a config file.. some say command prompt. I have my subversion repo set up on a windows 2008 server. I tried to go to command prompt and type svn:ignore name but that didnt work. The tutorial I used to set up my repo (with apache 2.2) had me create an etc folder in c:/. There I have subversion.conf, svn-acl and svn-auth-file. My subversion.conf file includes this: <Location /btp> DAV svn SVNPath C:/Files/Work/Repositories/btp AuthType Basic AuthName "By The Pixel Repo" AuthUserFile c:/etc/svn-auth-file Require valid-user AuthzSVNAccessFile c:/etc/svn-acl </Location> The client I use for my development machines is tortoisesvn. Im a bit of a noob so any help is appreciated it! Thanks.
