• C++/MFC: Handling multiple CListCtrl's headers HDN_ITEMCLICK events

  - by raph.amiard

  I'm coding an MFC application in which i have a dialog box with multiple CListCtrls in report view. I want one of them to be sortable. So i handled the HDM_ITEMCLICK event, and everything works just fine .. Except that if i click on the headers of another CListCtrl, it does sort the OTHER CListCtrl, which does look kind of dumb. This is apparently due to the fact that headers have an ID of 0, which make the entry in the message map look like this : ON_NOTIFY(HDN_ITEMCLICK, 0, &Ccreationprogramme::OnHdnItemclickList5) But since all the headers have an id of zero, apparently every header of my dialog sends the message. Is there an easy way around this problem ?

• How to track different button clicks with Google Analytics and AJAX?

  - by citronas

  I have several pages, let's call them A, B and C. Each of these pages has a form where the user can type in some information and click a button to send those information to the server. This button click is performed in an UpdatePanel to prevent a full postback. A customer of ours now wants to know how many % of the using visiting each site (A, B and C have different URLs) use this form. (Meaning I need seperate values for A, B and C) How to I track this in Google Analytics? It seems that I have to create a conversion(??) for each page. Is that correct? How must I modify the existing web application to let Google Analytics know, that a user submitted the form. (without the need to redirect thank to xy amount of different thank you pages) The only piece of information I've found so far is this: http://www.google.com/support/googleanalytics/bin/answer.py?hl=en&answer=55519 Unfortunately, this FAQ entry does not cover my answer.

• disable text drag and drop

  - by maniek

  There is a common feature of modern browsers where a user can select some text and drag it to an input field. Within the same field it causes moving of text, between different fields it does copying. How do I disable that? If there is no portable way, I am mostly interested in firefox. This is an intranet webapp, so I am also interested in modifying the browser/getting a plugin to do this. Maybe some system-level settings (I`m on windows XP)? I need to keep the default select-copy-paste functionality. The background is I have multiple-field data entry forms, and users often drag something by mistake.

• Rails Cache Sweeper and Model Callback Firing

  - by Topher Fangio

  Hey guys, I have the following classes: class Vigil < ActiveRecord::Base after_update :do_something_cool private def do_something_cool # Sweet code here end end class NewsFeedObserver < ActionController::Caching::Sweeper observe Vigil def after_update # Create a news feed entry end end Everything works as expected. The after_update in the sweeper requires that the do_something_cool method in the model has finished before it can run properly. The problem is that the after_update in the sweeper is being called before (or perhaps at the same time as) the do_something_cool callback and it's causing problems. Does anyone know how to force the after_update in the sweeper to fire after the model callback? Is there better way to achieve this?

• Excel VBA to check autofilter for data

  - by cav719

  I need help checking for autofiltered rows not including the header. I want it to give a message box "No records found." then exit sub or continue with copy paste if there are rows beyond the header row. I know I need an If/Else entry after the filter to check for data but I'm having trouble figuring how to check. This code is being done from a UserForm I created. Here is my script: Private Sub Searchbycompanyfield_Click() If CompanyComboBox1.Value = "" Then MsgBox "Please enter a Company to begin search." Exit Sub End If ActiveSheet.Range("$A:$H").AutoFilter Field:=1, Criteria1:=EQDataEntry.CompanyComboBox1.Value, Operator:=xlOr Cells.Select Selection.Copy Sheets("Sheet2").Select Range("A5").Select ActiveSheet.Paste Call MessageBoxYesOrNoMsgBox End Sub Any help would be greatly appreciated.

• How to structure a multilingual website for search engines?

  - by Nirmal

  I have this website which decides on the display language by a GET parameter. http://www.mysite.com/index.php?page=home&locale=en which is rewritten as http://www.mysite.com/en/home When no language is specified, the system defaults to English (en). Now how do I tell the search engines that many versions of the website exist? When the search bot enters the site, it will trigger the default English Language and after finishing, will just leave the site without considering other languages. I can very well have a sitemap with links to the default pages of each language, so the bot can navigate from there. But how do I say the bot that the entry in the sitemap is the home page for that language? Like if someone searches for 'mi sitio', they should be presented with the result http://www.mysite.com/es/home and not some other internal page. Any light on this? Thanks.

• Using a "vo" for joined data?

  - by keithjgrant

  I'm building a small financial system. Because of double-entry accounting, transactions always come in batches of two or more, so I've got a batch table and a transaction table. (The transaction table has batch_id, account_id, and amount fields, and shared data like date and description are relegated to the batch table). I've been using basic vo-type models for each table so far. Because of this table structure structure, though, transactions will almost always be selected with a join on the batch table. So should I take the selected records and splice them into two separate vo objects, or should I create a "shared" vo that contains both batch and transaction data? There are a few cases in which batch records and/or transaction records. Are there possible pitfalls down the road if I have "overlapping" vo classes?

• Factorial Algorithms in different languages

  - by Brad Gilbert

  I want to see all the different ways you can come up with, for a factorial subroutine, or program. The hope is that anyone can come here and see if they might want to learn a new language. Ideas: Procedural Functional Object Oriented One liners Obfuscated Oddball Bad Code Polyglot Basically I want to see an example, of different ways of writing an algorithm, and what they would look like in different languages. Please limit it to one example per entry. I will allow you to have more than one example per answer, if you are trying to highlight a specific style, language, or just a well thought out idea that lends itself to being in one post. The only real requirement is it must find the factorial of a given argument, in all languages represented. Be Creative! Recommended Guideline: # Language Name: Optional Style type - Optional bullet points Code Goes Here Other informational text goes here I will ocasionally go along and edit any answer that does not have decent formatting.

• Visual Studio Add-in - How do I create an Installer?

  - by Morgeh

  I have made a Visual Studio Add-in as part of a project I'm working on using web services. When I created the new Add-in project in visual studio it generated all the code required and installed the blank add-in on my pc (I assume). Since this is a large project we are using svn to manage the code base and once I had done some of the work on the Add-in I commited it, then checked it out on a different pc and attempted to run it. However on the other pc when I run the add-in in debug mode, the tools entry for the add-in is not present and I can't run the add-in. Am I right in assuming that when I created the project on the other pc it installed the plugin aswell?? and does that mean that I will need to create an installer for any other pcs I wish to use? Obviously at some point I intend on making an installer anyway but not untill after the development of the addin is complete.

• Are there cross-platform tools to write XSS attacks directly to the database?

  - by Joachim Sauer

  I've recently found this blog entry on a tool that writes XSS attacks directly to the database. It looks like a terribly good way to scan an application for weaknesses in my applications. I've tried to run it on Mono, since my development platform is Linux. Unfortunately it crashes with a System.ArgumentNullException deep inside Microsoft.Practices.EnterpriseLibrary and I seem to be unable to find sufficient information about the software (it seems to be a single-shot project, with no homepage and no further development). Is anyone aware of a similar tool? Preferably it should be: cross-platform (Java, Python, .NET/Mono, even cross-platform C is ok) open source (I really like being able to audit my security tools) able to talk to a wide range of DB products (the big ones are most important: MySQL, Oracle, SQL Server, ...)

• Can I use a class as an object in .NET to create instances of that class?

  - by Troy

  I'm writing a fairly uncomplicated program which can "connect" to several different types of data sources including text files and various databases. I've decided to implement each of these connection types as a class inherited from an interface I called iConnection. So, for example, I have TextConnection, MySQLConnection, &c... as classes. In another static class I've got a dictionary with human-readable names for these connections as keys. For the value of each dictionary entry, I want the class itself. That way, I can do things like: newConnection = new dict[connectionTypeString](); Is there a way to do something like this? I'm fairly new to C# so I'd appreciate any help.

• Cast/initialize submodels of a Backbone Model

  - by nambrot

  I think I have a pretty simple problem that is just pretty difficult to word and therefore hard to find a solution for. Setup: PathCollection is a Backbone.Collection of Paths Path is a Backbone.Model which contains NodeCollection (which is a Backbone.Collection) and EdgeCollection (which is a Backbone.Collection). When I fetch PathCollection paths = new PathCollection() paths.fetch() obviously, Paths get instantiated. However, I'm missing the spot where I can allow a Path to instantiate its submodels from the attribute hashes. I can't really use parse, right? Basically im looking for the entry point for a model when its instantiated and set with attributes. I feel like there must be some convention for it.

• Restoring web session in struts2

  - by bozo

  Hi, I have a classical scenario of a website and payment gateway integration, where the request for payment is sent to payment processor, and the payment processor calls back my application once it's done with some parameters I passed to it in the original request. Among parameters, we pass jsessionid and we expect that when the remote server makes request to our server (via customer browser redirect to our server) that the session will be the same as the session used to send the initial payment request. This does not happen, we have two different sessions, although the payment processor includes our original jsessionid in the request to us (https://blabla/?jsessionid=something). How should we go about recreating a session in struts2, in the only thing that connects the 'OLD' and 'NEW' session is the jsessionid in the request URL? Any ideas? Is this possible at all or is the 'OLD' session data deleted when the user moves away from our server onto a completely different domain of a payment processor with their data-entry form? This would explain our innability to recreate the session. Thanks a lot for your replies.

• How can I convert arbitrary strings to CLS-Compliant names?

  - by Brian Hinchey

  Does anyone know of an algorithm (or external library) that I could call to convert an arbitrary string (i.e. outside my control) to be CLS compliant? I am generating a dynamic RDLC (Client Report Definition) for an ASP.Net Report Viewer control and some of the field names need to be based on strings entered by the user. Unfortunately I have little control over the entry of the field names by the client (through a 3rd party CMS). But I am quite flexible around substitutions required to create the compliant string. I have a reactive hack algorithm for now along the lines of: public static string FormatForDynamicRdlc(this string s) { //We need to change this string to be CLS compliant. return s.Replace(Environment.NewLine, string.Empty) .Replace("\t", string.Empty) .Replace(",", string.Empty) .Replace("-", "_") .Replace(" ", "_"); } But I would love something more comprehensive. Any ideas? NOTE: If it is of any help, the algorithm I am using to create the dynamic RDLC is based on the BuildRDLC method found here: http://csharpshooter.blogspot.com/2007/08/revised-dynamic-rdlc-generation.html

• Simple XML parsing with Google Picasa API and JQuery

  - by zeedog

  I'm starting to look into Google's Picasa API for photo data, which provides you with a big XML file with info about albums and photos. I'm doing some quick and dirty tests to parse the XML file (which is saved locally to my hard drive for now) with JQuery and pull out the album id's, which are stored as "gphoto:id" tags, and display them in a div: $(document).ready(function() { $.get( 'albums.xml', function(data) { $(data).find('entry').each(function() { var albumId = $(this).children('gphoto:id').text(); $('#photos').append(albumId + '<br />'); }) }) }) I'm getting the following error in the console: jquery.js:3321 - Uncaught Syntax error, unrecognized expression: Syntax error, unrecognized expression: id This will work with other tags in the XML file (such as title, author, updated, etc.), but I'm trying to understand what's going on here. Does it have to do with the colon in "gphoto:id", somehow?

• Is this a valid jquery getJSON call?

To make a parameter optional its type should be either a reference type or a Nullable type.<br> Parameter name: parameters

• Add blank cell at end of UITable

  - by Michael

  I'm trying to add an additional cell for custom content as the last cell in a tableView, without altering the dictionary that creates the other content of the table. I think the place to add it is in cellForRowAtIndexPath rather than adding one to the numberOfRowsInSection, which just crashes if I do. I get a cellCount from the dictionary that creates the data for the table, then in cellForRowAtIndexPath, I have: if (indexPath.row == cellCount) { ... stuff goes here return cell; } of course, this never gets called. If I do if (indexPath.row == cellCount -1) it overwrites the last cell with content. I can get this to work if I add a blank entry into the xml from which I am populating the dictionary, but that's ugly. Example code would be neat!

• Change .NET Framework version of application pool to 3.5?

  - by Sean Sexton

  I've installed .NET Framework 3.5 SP1 on web server (Server 2008 Enterprise), so running IIS 7.0. I want to change the version of .NET Framework used by an existing site. So I right-click on appropriate Application Pool and selected Edit Application Pool. The .NET Framework dropdown does not include an explicit entry for framework 3.5, but just 2.0.50727. Does anyone know off the top of their head--is this just because the version of the core RTL in 3.5 is still 2.0? Or do I need to do something additional to get IIS to see version 3.5? (Did try restarting IIS). Thanks!

• Free (as in beer) Reverse Image Search API/Library/Service

  - by Bauer

  TinEye provides a great way to "reverse" search by image (i.e. upload/transload an image and have multiple possible sources of that image returned as results.) Since screen-scraping is messy and unreliable, I'm looking for a free API/library/web-service that could offer the same (or similar) reverse-image search function. At present, TinEye offers a commercial API, but since I'll only be using the service for small personal projects, it's hard to justify the cost of the service (the lowest being 1,000 searches for $70 USD). Is anyone aware of such a free service? Or is there a simpler way to approach this (programmatic solution; any language)? I understand that this is a tall order, and submitting the question is really only a last resort in the hope that there is some solution.

• Git push works for gitosis but not my own repo (Permission denied)

  - by Mickey Cheong

  Hi, I follow this exact guide to setup my GIT server: http://blog.agdunn.net/?p=277 I tried it before and it works. However, this time, when I provision a new server, it doesn't. I followed the exact steps and I provision it 3 times. It still failed. I get this errors: Permission denied (publickey). fatal: The remote end hung up unexpectedly However, this only happen when I try to add a remote origin and push my new repo. If I do a git push on my gitosis, it works perfectly fine. I tried look into the IP and all the permission, I can't figure out what went wrong. Another test I did was, I went into .ssh/known_hosts/ and delete the IP entry. When I tried to do a git push for gitosis-admin, it will prompt if I wanted to allow this IP. However, this prompt doesn't appear for my new repo. Any help will be great appreciated. Thanks, Mickey

• How to do manual DI with deep object graphs and many dependencies properly

  - by Fabian

  I believe this questions has been asked in some or the other way but i'm not getting it yet. We do a GWT project and my project leader disallowed to use GIN/Guice as an DI framework (new programmers are not going to understand it, he argued) so I try to do the DI manually. Now I have a problem with deep object graphs. The object hierarchy from the UI looks like this: AppPresenter-DashboardPresenter-GadgetPresenter-GadgetConfigPresenter The GadgetConfigPresenter way down the object hierarchy tree has a few dependencies like CustomerRepository, ProjectRepository, MandatorRepository, etc. So the GadgetPresenter which creates the GadgetConfigPresenter also has these dependencies and so on, up to the entry point of the app which creates the AppPresenter. Is this the way manual DI is supposed to work? doesn't this mean that I create all dependencies at boot time even I don't need them? would a DI framework like GIN/Guice help me here?
