  • Subversion same revision for tagging or committing multiple projects

    - by cubanacan
    How to make tags for multiple projects within one revision? For example, if it needs to tag with the same name: svn copy svn://localhost/BigProject/Project1/trunk svn://localhost/BigProject/Project1/tags/1.0.0 --message "1.0.0" svn copy svn://localhost/BigProject/Project2/trunk svn://localhost/BigProject/Project2/tags/1.0.0 --message "1.0.0" ... svn copy svn://localhost/BigProject/ProjectX/trunk svn://localhost/BigProject/ProjectX/tags/1.0.0 --message "1.0.0" But that snippet makes X revisions. So, how to make just one revision or how to integrate all in one? Another question is, how to commit similar modifications within one revision? TIA

  • Does database affect classes?

    - by satyanarayana
    I had created one class User and UserDAOImpl class for querying DB using class User. As there is one table to be queried, these two classes are sufficient for me. What if there is a case where new fields are to be added to that one table is to be divided into 3 tables( user_info, user_profile and user_address) to store user? As new fields are added, I need to change classes User and UserDAOImpl, it seems these two are not sufficient. It seems database changes affect my classes. In this case, do I need to divide class User into 3 classes as tables are changes? Can any one suggest me how can I solve this without making too many changes?

  • What's this UI pattern called?

    - by Bears will eat you
    I'm trying to figure out what this sort of thing is called, and eventually how I can create one in a web browser. It looks like this (screenshot of the first app that came to mind): The specific component/pattern I'm looking for is the two list boxes ("Included Gear" and "Excluded Gear") that represent inclusion/exclusion of items from a set. I'm not really looking for the WPF name (if there is one) but it might be helpful. I am looking for the name of this thingy, if there is one, and if you really want to make my day, you can point me toward a jQuery or YUI way of making one of these dealies in a browser. In case you were wondering, the screenshot is a World of Warcraft gear optimization program. Go figure why it was the first program that came to mind when I was trying to think of an example.

  • a good Java guide

    - by Lo'oris
    Do you know a good guide for Java, such as "dive into python" for python? If I searched google I expect I would find tons of random guides, but trying them all until I found a good one could take ages... that's why I am asking: do you already know one in particular? one you KNOW is good? I already know C, PHP and a bit of Python, if that matters.

  • Notepad++ regular expression find and replace $_REQUEST with $_GET but a more secure

    - by David
    What I am doing is replacing, in a large program, all $_REQUEST['var'] and mysql_escape_string($_REQUEST['var']) with either the 1st or 2nd line below the dotted line. Now, I have figured out this much of the regular expression but I would like to make it simpler. Instead of having to run the top one first then the 2nd one I would like to just run one all together. I tried this but it did not work. (mysql_escape_string\()*$_REQUEST\[\'([^']*)\'\]\)(\)*) So below is what works but again have to do it twice. $_REQUEST\[\'([^']*)\'\] mysql_escape_string\($_REQUEST\[\'([^']*)\'\]\) (isset($_GET['\1'])?mysql_real_escape_string($_GET['\1']):false) (isset($_POST['\1'])?mysql_real_escape_string($_POST['\1']):false) ============================ Update: Yeah, after some research I figured out that Notepad++ does not support most regular expressions. I guess one additional step can not hurt a person. It's just laziness. *NOTE: BUT if anyone wants to try feel free to comment. At least it is just 2 steps and not 20.

  • Help with validation rules

    - by George Garman
    I am trying to figure out how to validate a section of a form using php. If at least one of value 1-5 is checked, then at least one of value A-E must be checked. Value's A-E cannot be allowed without at least one of 1-5 being checked. Multiple values in each section can be selected, as long as there is at least one value in each section checked. I have tried individual IF statements and arrays without success. Does anyone have any suggestions or examples? I am missing something and I am certain it is pretty obvious, right in my face.

  • Safe way for getting/finding a vertex in a graph with custom properties -> good programming practice

    - by Shadow
    Hi, I am writing a Graph-class using boost-graph-library. I use custom vertex and edge properties and a map to store/find the vertices/edges for a given property. I'm satisfied with how it works, so far. However, I have a small problem, where I'm not sure how to solve it "nicely". The class provides a method Vertex getVertex(Vertexproperties v_prop) and a method bool hasVertex(Vertexproperties v_prop) The question now is, would you judge this as good programming practice in C++? My opinion is, that I have first to check if something is available before I can get it. So, before getting a vertex with a desired property, one has to check if hasVertex() would return true for those properties. However, I would like to make getVertex() a bit more robust. ATM it will segfault when one would directly call getVertex() without prior checking if the graph has a corresponding vertex. A first idea was to return a NULL-pointer or a pointer that points past the last stored vertex. For the latter, I haven't found out how to do this. But even with this "robust" version, one would have to check for correctness after getting a vertex or one would also run into a SegFault when dereferencing that vertex-pointer for example. Therefore I am wondering if it is "ok" to let getVertex() SegFault if one does not check for availability beforehand?

  • Is there a way to make sure classes implementing an Interface implement static methods?

    - by Tobias Kienzler
    Frist of all, I read erickson's usefull reply to "Why can’t I define a static method in a Java interface?". This question is not about the "why" but about the "how then?". So basically I want one Interface to provide both usual methods and e.g. a getSimilarObject method. For (a made up) example public interface ParametricFunction { /** @return f(x) using the parameters */ static abstract public double getValue(double x, double[] parameters); /** @return The function's name */ static abstract public String getName(); } and then public class Parabola implements ParametricFunction { /** @return f(x) = parameters[0] * x² + parameters[1] * x + parameters[2] */ static public double getValue(double x, double[] parameters) { return ( parameters[2] + x*(parameters[1] + x*parameters[0])); } static public String getName() { return "Parabola"; } } Since this is not allowed in the current Java standard, what is the closest thing to this? The idea behind this is putting several ParametricFunction's in a package and use Reflection to list them all, allowing the user to pick e.g. which one to plot. Obviously one could provide a loader class containing an array of the available ParametricFunction's, but every time a new one is implemented one has to remember adding it there, too.

  • Parsing command line options in Perl

    - by Jay Gridley
    Hi guys, I am parsing command line options in Perl using Getopt::Long. I am forced to use prefix - (one dash) for short commands (-s) and -- (double dash) for long commands (ex. --input=file), but problem is, that there is one special option (-r=) so it is long option for its requirement for argument, but it has to have one dash (-) prefix not double dash (--) like other long options. Is possible to setup Getopt::Long to accept these?

  • Is it possible to aggregate over differing where clauses?

    - by BenAlabaster
    Is it possible to calculate multiple aggregates based on differing where clauses? For instance: Let's say I have two tables, one for Invoice and one for InvoiceLineItems. The invoice table has a total field for the invoice total, and each of the invoice line item records in the InvoiceLineItems table contains a field that denotes whether the line item is discountable or not. I want three sum totals, one where Discountable = 0 and one where Discountable = 1 and one where Discountable is irrelevant. Such that my output would be: InvoiceNumber Total DiscountableTotal NonDiscountableTotal ------------- ----- ----------------- -------------------- 1 53.27 27.27 16.00 2 38.94 4.76 34.18 3... The only way I've found so far is by using something like: Select i.InvoiceNumber, i.Total, t0.Total As DiscountableTotal, t1.Total As NonDiscountableTotal From Invoices i Left Join ( Select InvoiceNumber, Sum(Amount), From InvoiceLineItems Where Discountable = 0 Group By InvoiceNumber ) As t0 On i.InvoiceNumber = t0.InvoiceNumber Left Join ( Select InvoiceNumber, Sum(Amount) From InvoiceLineItems Where Discountable = 1 Group By InvoiceNumber ) As t1 On i.InvoiceNumber = t1.InvoiceNumber This seems somewhat cumbersome, it would be nice if I could do something like: Select InvoiceNumber, Sum(Amount) Where Discountable = 1 As Discountable Sum(Amount) Where Discountable = 0 As NonDiscountable Group By InvoiceNumber I realize that SQL is completely invalid, but it logically portrays what I'm trying to do... TIA P.S. I need this to run on a SQL Server 2000 instance, but I am also interested (for future reference) if/how I would achieve this on SQL Server 2005/2008.

  • Spring singleton lifecycle

    - by EugeneP
    Reading this When a bean is a singleton, only one shared instance of the bean will be managed and all requests for beans with an id or ids matching that bean definition will result in that one specific bean instance being returned. Will be managed... What does that mean? If there's only one object, than any modification to this object will result in that every another attempt to get this bean will return a modified instance??

  • How do you disable a specific plugin in Vim?

    - by Zxaos
    I have Vim set up to use the excellent NERDTree plugin. However, there are some environments where I do not want this plugin to be loaded. In my .vimrc I have a sections that are only run when specific environment variables are true. In one of these sections I would like to disable the loading of NERDTree but all of the information I've come across states how to disable all plugins, not just one. Could someone demonstrate how to disable the loading of one specific plugin in Vim?

  • Ajax auto-populate from field when another form field is filled out

    - by Jon
    Has anyone used javascript/ajax to take data from one form field and put it into another? I'm trying to create a form that when one text input is filled out a second is auto-populated with the first letter of the word that is in the first text input. I'm thinking I can limit the second text input to one character to help get the desired result, but I'm not having luck finding the javascript to get the second text input to auto-populate from the first. Any suggestions?
