• Coldfusion 9 Inter portlet communication?

  - by Jakub

  I am having a hard time trying to find documentation at achieving IPC using Coldfusion 9 portlets under JBOSS. Does anyone have any good references I can take a look at? Or maybe some example code that I can go off of? So far I've been successful in getting my portlets working under Liferay (JBOSS), form submission, different views (edit/help) all work fine. Just need to know how to have one portlet on the page talk with another portlet. So far have been unsuccessful :( Anyone?

• Fulltext and composite indexes and how they affect the query

  - by Brett

  Just say I had a query as below.. SELECT name,category,address,city,state FROM table WHERE MATCH(name,subcategory,category,tag1) AGAINST('education') AND city='Oakland' AND state='CA' LIMIT 0, 10; ..and I had a fulltext index as name,subcategory,category,tag1 and a composite index as city,state; is this good enough for this query? Just wondering if something extra is needed when mixing additional AND's when making use of the fulltext index with the MATCH/AGAINST. Edit: What I am trying to understand is, what happens with the additional columns that are within the query but are not indexed in the chosen index (the fulltext index), the above example being city and state. How does MySQL now find the matching rows for these since it can't use two indexes (or can it?) - so, basically, I'm trying to understand how MySQL goes about finding the data optimally for the columns NOT in the chosen fulltext index and if there is anything I can or should do to optimize the query.

• Oracle sequence but then in MS SQL Server

  - by Raymond

  In Oracle there is a mechanism to generate sequence numbers e.g.; CREATE SEQUENCE supplier_seq MINVALUE 1 MAXVALUE 999999999999999999999999999 START WITH 1 INCREMENT BY 1 CACHE 20; And then execute the statement supplier_seq.nextval to retrieve the next sequence number. How would you create the same functionality in MS SQL Server ? Edit: I'm not looking for ways to automaticly generate keys for table records. I need to generate a unique value that I can use as an (logical) ID for a process. So I need the exact functionality that Oracle provides.

• Java: How to test methods that call System.exit()?

  - by Chris Conway

  I've got a few methods that should call System.exit() on certain inputs. Unfortunately, testing these cases causes JUnit to terminate! Putting the method calls in a new Thread doesn't seem to help, since System.exit() terminates the JVM, not just the current thread. Are there any common patterns for dealing with this? For example, can I subsitute a stub for System.exit()? [EDIT] The class in question is actually a command-line tool which I'm attempting to test inside JUnit. Maybe JUnit is simply not the right tool for the job? Suggestions for complementary regression testing tools are welcome (preferably something that integrates well with JUnit and EclEmma).

• How to Create VBA Add-In with Shared Codes for All Excels?

  - by StanFish

  I'm writing VBA codes for multiple Excel spreadsheets, which will be shared with others from time to time. At some point I find there are lots of duplications in my works. So I want to find a way to share codes in a sort of Excel add-in, like the .xla file. But when I tried to save the Excel file containing shared codes as .xla file, I got some problems: The file cannot be edit anymore after I save it in the default add-in folder If I move the .xls file to a folder other than the add-in folder, and open it directly - I cannot use its classes - which creates problems for sharing the codes Any ideas to create add-ins in a flexible and powerful way please? Thanks a lot for the help

• How to access the user font settings of the Internet Explorer?

  - by Mil

  I would like to access the Internet Explorer user settings for fonts, especially the font family, within a Browser Helper Object written in C#. I have looked into SHDocVw.WebBrowser and IHTMLDocument( to 5) but I don't see what I'm looking for or missing the property. The BHO is for Internet Explorer 7. Thank you very much! Edit: Richard asks why I need this information: The font-family you can adjust in the IE7 settings is used if the given font-families by the HTML document or CSS are not installed on the system. I need this application-based font-family which is used to render the text in the last instance (if all other information fail).

• Parsing HTML with XPath and PHP

  - by Peter

  Is there a way (using XPath and PHP) to do the following (WITHOUT external XSLT files)? Remove all tables and their contents Remove everything after the first h1 tag Keep only paragraphs (INCLUDING their inner HTML (links, lists, etc)) I received an XSLT answer here, but I'm looking for XPATH queries that don't require external files. Currently, I've got the HTML in question loaded into a SimpleXmlElement via: $doc = @DOMDocument::loadHTML($xml); $data = simplexml_import_dom($doc); Now I need help with: $data = $data->xpath('??????'); Been working with this one for several days to no avail. I really appreciate the help. Edit: I don't particularly care what's inside the paragraphs, as I can use strip_tags to eliminate what I don't want. All I need to do is to isolate the paragraphs from the rest of the source. I suppose a more specific, accurate requirement would be this: Return only paragraphs (and their html contents) that aren't contained in tables, and only before the first h1 tag

• How to handle splitting a file under source control?

  - by sharptooth

  I have a .cpp file and .h file containing a class. Class.cpp contains the implementation and Class.h contains the definition. The class is overcomplicated so I want to separate some code and move it into a separate class. So I create NewClass.cpp and NewClass.h and move the code there. How do I handle this when the files are under SVN? I can simply "svn add" the two new files, but then they will appear as new and will have no history. I could instead "svn copy and rename" the two initial files and edit the the two old files and the two new files - then the two new files will have common history. Which approach is better from the point of version control? Should the new files share history with the old files or should they appear as new?

• How to implement User routing like that in StackOverflow ?

  - by rockinthesixstring

  I've looked at the routing on StackOverflow and I've got a very noobie question, but something I'd like clarification none the less. I'm looking specifically at the Users controller http://stackoverflow.com/Users http://stackoverflow.com/Users/Login http://stackoverflow.com/Users/124069/rockinthesixstring What I'm noticing is that there is a "Users" controller probably with a default "Index" action, and a "Login" action. The problem I am facing is that the login action can be ignored and a "UrlParameter.Optional [ID]" can also be used. How exactly does this look in the RegisterRoutes collection? Or am I missing something totally obvious? EDIT: Here's the route I have currently.. but it's definitely far from right. routes.MapRoute( _ "Default", _ "{controller}/{id}/{slug}", _ New With {.controller = "Events", .action = "Index", .id = UrlParameter.Optional, .slug = UrlParameter.Optional} _ )

• DNS Lookup in simple C#/asp.net ajax call is extremely slow

  - by Ryan

  I'm running this out of the VS 2008 debugger on Windows 7, running .Net 3.5. The idea was to make all ajax requests with jQuery only, rather than .net, following some tutorials online. Default.aspx - HTML page, jquery triggers method in Default.aspx.cs http://pastebin.com/pxBvKA2H Default.aspx.cs - C# Webform, just defines a GetDate fuction, which only returns a string for now (trying to eliminate any possible issues) (can only post one hyperlink...) pastebin.com/pnHn50hu The ajax query takes longer than it should. Profiling with firebug revealed that it took 1.03 ms. 1s DNS Lookup | 26ms Waiting | 1ms Receiving EDIT: It continues to take the same set of times if you continue to click and resubmit the request. Is there anything I can do to cut down on the DNS Lookup time / what did I do wrong? Thanks for any help.

• How do I get PyLint to find namespace packages?

  - by tjd.rodgers

  I have a virtualenv where I've installed two packages, both using the company.project_name namespace. So the first package is importable from company.project_name.one and the second from company.project_name.two. The challenge is that I can't seem to be able to run PyLint on either one of them. If I issue: $ pylint company.project_name.one I get: ************* Module company.project_name.one F: 1, 0: No module named project_name.one(fatal) I suspect that I'm probably doing something wrong. Is there a proper way to do this? Edit: I should have made it clear that company.project_name and company are namespace packages and not regular packages.

• Is there a Javascript library for editing PDFs?

  - by Fletcher Moore

  Based on my Google and stackoverflow search I'm guessing no, but it can't hurt to ask. The goal is: store some blank forms on my server. Then present these to the user, who edits the form in the browser with Javascript and submits the form back to the server. The client wants to reuse parts of an old system (the forms) in which users would download an editable PDF, edit it, and email it back to a secretary. Our users aren't very computer savvy and many don't realize they need to email the forms back, assuming instead the forms somehow get submitted when they save their local changes (or something). I haven't seen the forms yet, so I cannot assess the viability of an alternative.

• Is there a way to "freeze" a file in Git?

  - by Suan

  I'm in a situation where I want to open source my project, however there's a single source file that I want to release a "clean" version of, but use a separate version locally. Does git have a feature where I can just commit a file once, and it stops looking for changes on that file from now on? I've tried adding the file to .gitignore, but after the first time when I do a git add -f and git commit on the file, and I proceed to edit it again, git status shows the file as changed. The ideal behavior would be for git to not show this file as changed from now on, even though I've edited it. I'd also be interested in how others have dealt with "scrubbing" their codebases of private code/data before pushing to an open source repo, especially on Git.

• Is this class + constructor definition pattern overly redundant?

  - by Protector one

  I often come across a pattern similar to this: class Person { public string firstName, lastName; public Person(string firstName, string lastName) { this.firstName = firstName; this.lastName = lastName; } } This feels overly redundant (I imagine typing "firstName" once, instead of thrice could be enough…), but I can't think of a proper alternative. Any ideas? Maybe I just don't know about a certain design pattern I should be using here? Edit - I think I need to elaborate a little. I'm not asking how to make the example code "better", but rather, "shorter". In its current state, all member names appear 3 times (declaration, initialization, constructor arguments), and it feels rather redundant. So I'm wondering if there is a pattern (or semantic sugar) to get (roughly) the same behavior, but with less bloat. I apologize for being unclear initially.

• Something wrong with this gtk# class for a window?

  - by Isaiah

  Learning C#, I feel so guilty for loving it. I'm a microsoft hater. Anyways I'm trying out gtk# and just trying out some simple stuff. I've made a class for the main window and MonoDevelop is complaining about this code, which I swear was just fine a second ago. public class mwin{ protected Window win = new Window("test program--"); public mwin(){ //Configure the parts win.SetDefaultSize(300,500); } public void showWin(){ win.ShowAll(); } } win.SetDefaultSize(300,500); }--<(here it says "} expected") But obviously I have a closing brace! Am I missing something? [edit] here's whole code. The color stuff was some stuff I was playing around with to color the window, but I didn't finish because the error started. I'm sure it's not the color stuff because it still has an error when I comment them out. http://codepaste.net/b2mwys

• Passing parameters into ViewModels (Prism)

  - by vXtreme

  Hi I can't figure out how to pass parameters to my viewmodels from other views or viewmodels. For instance, I have a View called Customers. There is a grid inside, and if you double-click the grid, a new view is supposed to come up and allow you to edit that customer's data. But how will the View(Model) responsible for editing data know which customer it's supposed to open if I can't pass any parameters inside? EventAggregator is out of the question because I obviously can't create hundreds of eventargs, each for one view. And besides, it's a lousy solution. So far I was able to come up with: CustomerDataView custView = new CustomerDataView(customerId, currentContext); manager.Regions[RegionNames.Sidebar].AddAndActivate(custView); What do you think about this particular solution? Is this the way it's normally done? What I don't like about this is the fact that I lose out on automatic dependency injection by Unity.

• Can a signed Java Applet/Web Start manipulate content in a cross-site IFRAME?

  - by etoleb

  Is it possible for a signed Java Applet or Web Start app to write to the DOM of an IFRAME under a different domain? Does the fact that they're a signed applet/javaws allow them to ignore browsers' standard cross-browser security? If this does work, how well is it supported across the major browsers? Thanks! EDIT: My motivation is to add a browser plugin-like tool to third-party websites I don't control. It's not required that I use Java at all---any ideas or suggestions are encouraged.

• How can you logically group HTML elements without taking the help of CSS classes ?

  - by Perpetualcoder

  I know that in jQuery you can use something like $(".cssClass") to get all elements with this class. However in plain html and javascript how do you group elements logically? For example: <input id="fee1" data-id="1" data-group="Fees" type="text" value="$15.00"/> <input id="fee2" data-id="2" data-group="Fees" type="text" value="$25.00"/> <input id="fee3" data-id="3" data-group="Fees" type="text" value="$35.00"/> I want to create a javascript function like this: function GetByDataGroup(dataGroup){ /* returns something like [[1,"$15.00"],[2,"$25.00"],[3,"$35.00"]]*/ } EDIT : Due to some political reasons I cant use jQuery or any framework..i know it doesnt make sense :)

• Accessing variable from ARGV

  - by snaken

  I'm writing a cPanel postwwwact script, if you're not familiar with the script its run after a new account is created. it relies on the user account variable being passed to the script which i then use for various things (creating databases etc). However, I can't seem to find the right way to access the variable i want. I'm not that good with shell scripts so i'd appreciate some advice. I had read somewhere that the value i wanted would be included in $ARGV{'user'} but this simply gives "root" as opposed to the value i need. I've tried looping through all the arguments (list of arguments here) like this: #!/bin/sh for var do touch /root/testvars/$var done and the value i want is in there, i'm just not sure how to accurately target it. There's info here on doing this with PHP or Perl but i have to do this as a shell script. EDIT Ideally i would like to be able to call the variable by something other than $1 or $2 etc as this would create issues if an argument is added or removed Any ideas?

• Visual studio deployment project error when writing to registry

  - by Rekreativc

  Hello I have a setup for an application that was recently converted to be a framework 4.0 project (don't know if it's relevant). The setup has to write to registry (Local Machine) and until now this has always worked perfectly, however now it fails to write to registry on a clean machine (running Windows 7, 64 bit). The setup does not fail, does not show a warning of any kind, however it does not write to the registry (I even set AlwaysCreate property to true on every key, just in case) which of course causes the application to terminate on startup. What could be the cause of this? I have never encountered such an error before. Edit: I have tried running the installer as administrator, didn't change anything.

• How to detect tap on uiview with lots of controls?

  - by kodcu

  My problem is about tap detection. I have a uiviewcontroller and there are some controls on uiview (labels, buttons, tableview, imageview, etc..) When I tap the uibutton I display a small uiview (200x150), if the user taps the uibuttons in smallview I hide the smallview. But I can't hide the uiview if the user taps the background. I tried this code.. -(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ //NSLog(@"Touches began."); [self hideShareView]; } It doesn't work if I tap the another button in the uiviewcontrols view. I just want my uiviewcontrol's uiview to react first. I think its about firstResponder but I dont know how to set it first. edit: i want it to work like a uiPopover in ipad.

• Unit testing the app.config file with NUnit

  - by Dana

  When you guys are unit testing an application that relies on values from an app.config file? How do you test that those values are read in correctly and how your program reacts to incorrect values entered into a config file? It would be ridiculous to have to modify the config file for the NUnit app, but I can't read in the values from the app.config I want to test. Edit: I think I should clarify perhaps. I'm not worried about the ConfigurationManager failing to read the values, but I am concerned with testing how my program reacts to the values read in.

• Tracking DB changes with Zend Framework?

  - by Chad Johnson

  I am trying to decide between the Zend Framework and Ruby On Rails for my web application. If I go with ZF, I need the following: A way to incrementally track changes to my database, as with RoR's migration feature (001_something.sql, 002_something_else.sql). A place to put SQL for the next release of my software. At work in our custom PHP solution, we just have release.sql, which gets run, archived, and blanked out upon release. ZF has Zend_Db_Schema_Manager, which does the same thing, but I'm not interested as its not official, complete, or maintained. Is there an official mechanism that ZF provides for doing something similar to what I described? EDIT I ended up going with Rails. Nothing compares.

• VIsual Studio : ASP.NET Extra Page Files

  - by Matthew

  Is there any way to write a VS Add-In or something else that would allow me to be able to link files to an ASPX page in ASP.NET. My goal is to be able to have this extra file created with every ASPX page, and then use a custom MS Build Task to analyze those files and do some stuff. So for example, when I created "MyPage.aspx", I'd actually see these files on disk... MyPage.aspx MyPage.aspx.cs MyPage.aspx.designer.cs MyPage.aspx.MyExtension I want to be able to see the file when I expand a page and be able to edit the file. Possible?
