• Extending configuration for .Net 3.5 Applications

  - by Maximiliano Rios

  Due to a requirement in my current project, I have to build a configuration manager to handle configurations that merge local config info with database one. Custom configuration doesn't fit my needs, problem is that I don't know what's the type before loading certain information, for example: Loading database information I will able to know what's myhandler's type. Not previously. So I thought to write my own handler but I can't let set blank as type for sections, in fact .net requires to know what's the type to match myhandler nodes. I'm thinking on building a different parser to read XML nodes but I would prefer to match this structure. I've not found any information to do that yet, is there any way? Can I extend or hook up something into the framework to be capable of loading on-the-fly types and validate nodes? Thanks in advance.

• Anyone knows of a good addressbook implementation?

  - by Tsahi Levent-Levi

  I am looking to add an address book to one of my programs. For that purpose, I want to have something that is flexible and customizable to the point of allowing me to hook up additional metadata to contacts in it from third parties. I don't mind paying for a solution as long as I get something that is usable for me. My requirements: Optimized to run on embedded devices Preferably in source code form Ability to add my own fields to contacts over those the address book provides out of the box Ability to plugin "stuff" to it to enhance it without changing its base code too much Has a C or C++ interface

• Virtual pages for my plugin

  - by Fini

  Hi, I am currently in the process of making a WordPress Plugin which is going to parse some external data (products) from various web services and present them as normal pages in WordPress. I would like to avoid actually creating the pages programatically and instead just generate them on the fly to avoid any synchronization issues if a product is deleted and so forth. My plugin is going to have a base url in which it will hook on to, for example /products/, and then I would generate each product page by calling /products/some-product-name/. I also anticipate the need for uri's like /products/category/some-category-name/ which I will use to list all items in that category. Since I am new to WordPress plugin development, I am looking for some tips and advice to get me started on the right foot. Any help is highly appreciated ;)

• Java Annotations - Is there any helper library to read/process annotations?

  - by mjlee

  I start to use Java annotations heavily. One example is taking method with annotations and converting them into 'telnet'-based command-line command. I do this by parsing annotations and hook into jopt option parser. However, I do a lot of these manually. For example, Method parameter annotation processing.. Method method = ... //; Class[] parameters = method.getParamterTypes(); Annotation[][] annotations = method.getparamterAnnotations(); for( int i = 0; i < parameters.length; i++ ) { // iterate through the annotation , see if each param has specific annotation ,etc. } It is very redundant and tedious. Is there any opensource project that help processing Annotations?

• How do I watch a file for changes using Python?

  - by Jon Cage

  I have a log file being written by another process which I want to watch for changes. Each time a change occurrs I'd like to read the new data in to do some processing on it. What's the best way to do this? I was hoping there'd be some sort of hook from the PyWin32 library. I've found the win32file.FindNextChangeNotification function but have no idea how to ask it to watch a specific file. If anyone's done anything like this I'd be really grateful to hear how... [Edit] I should have mentioned that I was after a solution that doesn't require polling. [Edit] Curses! It seems this doesn't work over a mapped network drive. I'm guessing windows doesn't 'hear' any updates to the file the way it does on a local disk.

• Playing audio from a wav file in iPhone SpeakHere example

  - by Mo

  I'm working with the iPhone SpeakHere example, and I would like to be able to play audio from either the mic (as in the example) or from a wav file. I have working code to play from a particular wav file, which looks like this: NSString *path = [[NSBundle mainBundle] pathForResource:@"basketBall" ofType:@"wav"]; AVAudioPlayer* theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]; theAudio.delegate = self; [theAudio play]; So I'm fine with actually getting the wav to play in the application (I can hook it up to a button, etc.) but I would like it to also behave the same way pushing the "Play" button does after recorded speech, in that it should be connected to the same visualization (which I have modified quite a bit, but essentially shows the current volume, among other things). Thanks for your help!

• Office Interop addins installer?

  - by jimbojw

  I have three C# Solutions in Visual Stuido 2008, one each for Word, Excel and PowerPoint using interop to hook various events. In each Solution, I have exactly one class, the one created by default when using File - New - Project - Visual C# - Office - 2007. Now that I have my addins working properly, it's time to create an installer. I understand that I may also have to distribute the PIAs. I would like my installer to register itself such that it can be uninstalled via the normal Add/Remove Programs mechanism. My organization is somewhat standardized around WiX for creating installers, but I'm open to any suggestions. How do I produce an MSI or EXE capable of installing my addins? GUI/wizard for the installer is not necessary. I'm happy to RTFM - so far all the tutorials I've found only explain how to create the project and do some of the coding. Maybe I'm using the wrong search terms? Thanks in advance for any help!

• Intercept web requests from a WebView Flash plugin

  - by starkos

  I've got a desktop browser app which uses a WebView to host a Flash plugin. The Flash plugin makes regular requests to an external website for new data, which it then draws as fancy graphics. I'd like to intercept these web requests and get at the data (so I can display it via Growl, instead of keeping a desktop window around). But best I can tell, requests made by Flash don't get picked up by the normal WebView delegates. Is there another place I can set a hook? I tried installing a custom NSURLCache via [NSURLCache setSharedURLCache] but that never got called. I also tried method swizzling a few of the other classes (like NSCachedURLResponse) but couldn't find a way in. Any ideas? Many thanks!

• How can I integrate a bitbucket repository with the hosted on-demand version of FogBugz?

  - by carrier

  I use the on-demand (hosted) version of FogBugz. I would like to start using Mercurial for source control. I would like to integrate FogBugz and a BitBucket repository. I gave it a bit of a try but things weren't going very well. FogBugz requires that you hook up your Mercurial client to a fogbugz.py python script. TortoiseHg doesn't seem to have the hgext directory that they refer to in instructions. So has anyone successfully done something similar?

• Renaming Functions during runtime in PHP.

  - by The Rook

  In PHP 5.3 is there a way to rename a function or "hook" a function. There is the rename_function() within "APD" which has been broken since ~2004. If you try and build it on PHP 5.3 you'll get this error: 'struct _zend_compiler_globals' has no member named 'extended_info' This is a really easy error to fix, just change this line: GC(extended_info) = 1; to CG(compiler_options) |= ZEND_COMPILE_EXTENDED_INFO; I modified my php.ini and the APD shows up in my phpinfo() as it should. However when i call rename_function() the PHP page doesn't load and I get a segmentation fault in my /var/log/apache2/error.log. Is there anyway to fix APD to work with a modern version of PHP? Or is there another method to rename functions? Why on earth is vital feature not in php!??!?! (Gotta love python :)

• In Drupal, how to change the values passed to Pathauto?

  - by Vinicius Pinto

  I have Pathauto configured to generate an alias based on the title of a node, for a specific content type. The problem is that I want to make small changes in this title before Pathauto uses it to generate the alias. The first comment in this post suggests the use of hook_token_values, but I couldn't really understand how to use it, even after reading the docs. In my tests, when I implement this hook, the alias generated is always "array", which means I'm missing something. Any help? Thanks.

• Git to svn: Adding commit date to log messages

  - by Arnauld VM

  How should I do to have the author (or committer) name/date added to the log message when "dcommitting" to svn? For example, if the log message in Git is: This is a nice modif I'd like to have the message in svn be something like: This is a nice modif ----- Author: John Doo <[email protected] 2010-06-10 12:38:22 Committer: Nice Guy <[email protected] 2010-06-10 14:05:42 (Note that I'm mainly interested in the date, since I already mapped svn users in .svn-authors) Any simple way? Hook needed? Other suggestion? (See also: http://article.gmane.org/gmane.comp.version-control.git/148861) Thank you in advance. Yours faithfully, -- Arnauld Van Muysewinkel

• How good is my method of embedding version numbers into my application using Mercurial hooks?

  - by ArtB

  This is not quite a specifc question, and more me like for a criticism of my current approach. I would like to include the program version number in the program I am developing. This is not a commercial product, but a research application so it is important to know which version generated the results. My method works as follows: There is a "pre-commit" hook in my .hg/hgrc file link to .hg/version_gen.sh version_gen.sh consists solely of: hg parent --template "r{rev}_{date|shortdate}" > version.num In the makefile, the line version="%__VERSION__% in the main script is replaced with the content of the version.num file. Are there better ways of doing this? The only real short coming I can see is that if you only commit a specfic file, version.num will be updated, but it won't be commited, and if I tried to add always committing that file, that would result in an infite loop (unless I created some temp file to indicate I was already in a commit, but that seems ugly...).

• Are there such things as Email Hooks?

  - by viatropos

  After hearing about git commit hooks, I was thinking maybe there are such things as email hooks... Is it possible for me to build a program that says "hey, you just received an email, now run this ruby script"? Something like a GMail Web Hook. Is there anything out there like that? I mean I could build a cron thing that checked my email all the time, but maybe there's a more formal way. Looking for an online email system to do this with, not say my Mac Mail.

• Ethics of assisting other programmers, where do we draw the line?

  - by Chris

  In general, not just in relation to stackoverflow, sometimes I'm asked a programming question for which the answer will probably be used for good purposes, but there is a chance that it could not be. Two recent examples which reminded me of some real world questions I've been asked are: Send email to many users, and keep a formless application from closing for a keyboard hook Though I don't believe the intent of the authors of those questions is in any way nefarious, occasionally someone does ask such a question for purposes of aiding a spamming effort, or creating a keylogger. Even though the questioner and answerers had good intent, a 3rd party could pervert those answers to create a piece of malware or a spam utility. Should we always trust the questioner to use the answer for good? Should we feel obligated to ask the purpose of a question, and how the answer will be used? And how can we prevent answers from being overheard (when asked verbally) or being referenced (when posted publicly online) and then used for unsavory purposes?

• Apple Magic Trackpad Gestures carried out as personalized Commands in Windows

  - by Adele

  I want to have the Apple Magic Trackpad to work on Windows, but NOT as a regular Mouse! I will need the normal Trackpad Gestures to work with a c# Application (i.e. when carring out a 2 finger swipe to the left, it will start playing a song...). I guess I´ll have to write my own driver? Is there a way to use Apples MAgic Trackpad Driver for Windows and re-write that one? OR is there any way (API, self-written driver), so that I could just hook the gestures to my Commands? Or any RAW Input examples? Does anybody know how to do that, or where to start? Thank you so much, I´m really lost.

• jQuery hyperlinks - href value?

  - by Tom

  Hi, On my website I use jQuery to hook the events of elements, namely hyperlinks. As these hyperlinks only perform actions on the current page, and do not lead anywhere, I have been putting a href attribute of "#" in: <a href="#">My Link</a> However in some browsers this causes the page to scroll right to top which is obviously undesirable behaviour. I've tried using a blank href value, or not including one, but then the mouse does not change to the hand cursor upon hovering. What should I put in there?

• Binding for MinWidth property does not work in Silverlight

  - by Akash Kava

  I have noticed something very unusual today, I need to bind "MinWidth" property of TextBlock to some value, however following example does not work. It only accepts MinWidth at a time of creation, but after that it is not affected at all if LeftWidth property is changed at runtime, however if I bind LeftWidth property to WidthProperty it works well. Binding b = new Binding("LeftWidth"); // following never changes layout of control tb.SetBinding(TextBlock.MinWidthProperty,b); However, this one works correctly, // following never changes layout of control tb.SetBinding(TextBlock.WidthProperty,b); Now I also did hook events and tried to do InvalidateMeasure and InvalidateArrange on TextBlock, but it has no effect. Seems like Changing MinWidth Property after layout pass does not work at all. Can it be a bug in Silverlight? or Does anyone have any idea at all why MinWidth does not redo the layout?

• Stub web calls in Scala

  - by Dennis Laumen

  I'm currently writing a wrapper of the Spotify Metadata API to learn Scala. Everything's fine and dandy but I'd like to unit test the code. To properly do this I'll need to stub the Spotify API and get consistent return values (stuff like popularity of tracks changes very frequently). Does anybody know how to stub web calls in Scala, the JVM in general or by using some external tool I could hook up into my Maven setup? PS I'm basically looking for something like Ruby's FakeWeb... Thanks in advance!

• How can you configure or extend BITS (Background Intelligent Transfer Service) to read files from a

  - by Mark

  I have a ASP .NET load balanced application (webservice and website). It runs on SQL server. I need to be able to provide large files for download. However, because of the load balancing situation, the files are stored in the SQL database as opposed to the file system. BITS seems to be the best approach. I have full control of the client. However, i don't know how to configure BITS to read the file from the database. I know how to write the C# code for that, but i don't know how to get BITS to hook into it as opposed to reading the file from the file system. Any ideas?

• Git tool to remove lines from staging if they consist only of changes in whitespace

  - by Max Howell

  The point in removing trailing whitespace is that if everyone does it always then you end up with a diff that is minimal, ie. it consists only of code changes and not whitespace changes. However when working with other people who do not practice this, removing all trailing whitespace with your editor or a pre-commit hook results in an even worse diff. You are doing the opposite of your intention. So I am asking here if there is a tool that I can run manually before I commit that unstages lines from staging that are only changes in whitespace. Also a bonus would be to change the staged line to have trailing whitespace removed for lines that have code changes. Also a bonus would be to not do this to Markdown files (as trailing space has meaning in Markdown). I am asking here as I fully intend to write this tool if it doesn't already exist.

• How to get the last windows active time by windows api

  In general, the Screensaver will run when we do nothing for a period of time. Now i wanna know how to get the unactive time. In another word,i want to make a program which would run a function if we do nothing for a period of time. Now i can use mouse or keyboard hook to solve the problem. But you know,it needs administrator permissions. In another word,if in win vista or win 7,it is nauseating because of the UAC. I need an API such to get last windows active time.

• Comet with ASP.NET AsyncHttpHandlers

  - by Sumit

  I am implementing a comet using AsyncHttpHandlers in my current asp.net application. According to my implementation client initially sends Notification Hook request to server (with its user id) on AsyncHttpHandler, and on server side I maintain a Global (Application level) dictionary of userid(key) and IAynsResult (value). So when ever a request is received to send notification to a user I just pick the matching IAsyncResult from the Global Dictionary and send response to the client user. My concern is, is maintaing a Dictionary of Userid and IAsyncResult at Application level a good design? I feel it will put a lot of load on the server, at the time of high traffic. Is there any other way I can achieve the comet. or what will be the good design to achieve comet for high traffic scenarios.

• Inject Html Into a View Programmatically

  - by madcapnmckay

  Hi, I have a tricky problem and I'm not sure where in the view rendering process to attempt this. I am building a simple blog/CMS in MVC and I would like to inject a some html (preferably a partial view) into the page if the user is logged in as an admin (and therefore has edit privileges). I obviously could add render partials to master pages etc. But in my system master pages/views are the "templates" of the CMS and therefore should not contain CMS specific <% % markup. I would like to hook in to some part of the rendering process and inject the html myself. Does anyone have any idea how to do this in MVC? Where would be the best point, ViewPage, ViewEngine? Thanks, Ian
