• Problem with Regex in .NET (C#)

  - by Craig Bovis

  I'm trying to write a a regex to validate a string to match the following rules. Must start with a-z (case insensitive) Must only contain a-z A-Z 0-9 . - I've put something together based on my limited knowledge and ran it through an online testing tool for a whole bunch of situations and the results were as I had hoped however when I place the pattern into my .NET code it doesn't match correctly. The pattern I am using is, [a-zA-Z][a-zA-Z0-9.\-]* Is this the correct pattern or am I barking up the wrong tree? Some examples of what I'm expecting. craig.bovis - VALID 24craig - INVALID craig@bovis - INVALID craig24 - VALID -craig24 - INVALID craig24.bovis-test - VALID

• Modifying an old Windows program not to call exit after a keypress without source access

  - by rustyn2

  I have an older C++ Windows program that I've been asked to get run in a kiosk style environment for a student project. From the main menu, hitting ESC will exit the program, which is undesirable. In ye olden days I would have trapped the keyboard interrupt or whatever and dug around to NOOP whatever JMP or CALL was getting referenced in the case statement that likely decides all that, but on Windows everything goes through various registered event handlers, and I haven't done any windows internals work in about 10 years. Is there a good tool to breakpoint a program on certain WM_EVENT (WM_KEYDOWN being a prime target) messages or similar, so that I can narrow down where in the executable the check is made? I'm currently stepping back from various potential system calls made before the various thread cleanups and final exit calls but it seems like there has to be a better way to do this that I'm forgetting.

• Configure OutputCache for ASCX from web.config's cache profiles

  - by zar

  Hello, To configure aspx pages' OutputCache from one place, there is a great tool which is the CacheProfile attribute in <%@ OutputCache % associated with a custom cache profile defined in the web.config : <caching> <outputCacheSettings> <outputCacheProfiles> <add name="myProfile" duration="300" /> </outputCacheProfiles> </outputCacheSettings> </caching> And the line : <%@ OutputCache CacheProfile="myProfile" VaryByParam="None" %> does the job. But how to do the same thing for ascx user controls ? CacheProfile isn't in <%@ OutputCache % :S Is there a workaround ? Thanks.

• What is the best way to set up a PHP development environment on a Mac?

  - by Edward Tanguay

  When I do PHP, I use XAMPP to set up a development environment on Windows, then upload to Linux servers, works very well. I'm now passing on a PHP project to a person who has a Mac so he needs a local PHP dev environment. I noticed XAMPP has a version for Mac which I will recommend. But knowing that Mac is always a bit different, has anyone used any other easy PHP environment setup tool for the Mac, or I could even imagine that Mac solves this issue more elegantly by e.g. having a web server ready to go upon first boot etc. What is the best way to set up a PHP development environment on a Mac?

• JLabel which hides text after reaching certain length or number of values

  - by Patrick Kiernan

  The purpose of the JLabel is to show who a message is to, like in a mail client e.g. To: John, Mary, Peter, Frank, Tom, Harry I will have the names in a vector so can build up a string from that and then set the label's text to this string. However it has the potential to get quite long. I was think it might be nice to have something like this: To: John, Mary, Peter, Frank, Tom, Harry, ... Then when you click on the '...', it will expand more or just show a tool tip if you mouse over the ... Yes this idea is stolen from Thunderbird! I am open to other ideas, don't have to use a JLabel. Thanks.

• setProperty must be overridden by all subclasses of SOAPMessage

  - by Pablo

  I'm trying to deploy some web services in a WAR application on JBoss 5.1.0. I have created the source files from an existing wsdl using JAX-WS tool wsgen. This created the Service files and @XmlType annotated clases that would act as request and response wrappers. This classes worked well on JBoss 4.2.3, but when moving to JBoss 5.1.0, I get this exception. java.lang.UnsupportedOperationException: setProperty must be overridden by all subclasses of SOAPMessage My configuration: Windows XP SP3 (but getting the same on Vista, as well as on Linux) Sun JDK 1.6.0_17 JBoss 5.1.0 GA for jdk6 Thanks in advance!

• What is the best XPS WYSIWYG Editor that will output XAML?

  - by Simon

  I am looking for a WYSIWYG for XPS that will ouput the raw XAML. My intentions is use the tool for a way to quickly generate and test the XAML (of XPS documents) with the intention of then generating the same xaml in code and programmatically generating an XPS document. The same approach that many people use for generating html. Can anyone recommend any of the below products or suggest any others? Better yet does anyone know of a free XPS editor? NiXPS Edit $300USD http://www.nixps.com/nixps_edit_20.html XamlPad is free but also quite limited and does not really target XPS. Office System Power Tools is not WYSIWYG http://blogs.msdn.com/adrianford/archive/2008/07/03/visual-studio-and-xps-files.aspx XPS eXaminer 1.0 $399USD http://storefront.qualitylogic.com/p-16-qualitylogic-xps-examiner.aspx

• Where should I put my breakpoint to check XML Response string from a web service?

  - by burak ozdogan

  Hi, You know, once you add a web reference to a webservice a wrapper code is generated by Visuel Studio. I was wondering if there is a method (or property) which is generated by Visual Studio whatever web service you add to your project so that I can put a breakpoint there and once the debugger stops there, I can simply read the response from web-service in an xml format (or should I say, soap). I don't want to use fiddler or a tool like that. Is it possible? Does such a place exist in the webservice wrapper code for all the added webservice Thank you, burak ozdogan

• What is the easiest way to get an embedded upload progress bar using Ruby/Sinatra/Haml/Passenger/ngi

  - by mmr

  I have a website where people can upload 30+mb of data in a single block, and I want to be able to show them the progress of their upload without causing the web page to become unresponsive, similar to how flash uploads work in gmail. There's this question here, but I don't know if that progress bar is embedded in the page or if it's using the browser's progress bar. I'm also a bit of a web newb, so I'm not sure if it's the 'easiest'. I asked the swfupload guys how to do this here, and the answer I got is 'this tool requires some knowledge to use it' without giving me much help in figuring out where to get started. I also asked this question on ServerFault, and got no response, so maybe that was the wrong place to ask. I'm all for learning new things and so forth, but there are a lot of potential pathways to take here. Where should I start, and what do I need to know to make everything work with sinatra, haml, ruby, passenger, and nginx? Thanks!

• RegEx - Take all numeric characters following a text character

  - by Simon

  Given a string in the format: XXX999999v99 (where X is any alpha character and v is any numeric character and v is a literal v character) how can I get a regex to match the numeric characters following the v? So far I've got 'v\d\d' which includes the v but ideally I'd like just the numeric part. As an aside does anyone know of a tool in which you can specify a string to match and have the regex generated? Modifying an existing regex is one thing but I find starting from scratch painful! Edit: Re-reading this question I realise it reads like a homework assignment! However I can assure you it's not, the strings I'm trying to match represent product versions appended to product codes. The current code uses all sorts of substring expressions to retrieve the version part.

• Kink detection in drawn polylines

  - by David Rutten

  Users can sketch in my app using a very simple tool (move mouse while holding LMB). This results in a series of mousemove events and I record the cursor location at each event. The resulting polyline curve tends to be rather dense, with recorded points almost every other pixel. I'd like to smooth this pixelated polyline, but I don't want to smooth intended kinks. So how do I figure out where the kinks are? The image shows the recorded trail (red pixels) and the 'implied' shape as a human would understand it. People tend to slow down near corners, so there is usually even more noise here than on the straight bits.

• How can I easily print multiple layers on multiple pages in Visio

  - by Mark Robinson

  We've created a flow chart using Visio that has multiple layers. (The background is that each layer represents variations on a basic process.) Now we want to be able to print each layer individually. Currently this involves lots of clicking to select the correct layer and and then press print - then repeating this for each of the 10 layers. Is there a simpler way? E.g. define each layer once and use a "print each layer" tool / macro?

• ORM in the realworld

  - by josh

  I am begining a new project that i think will last for some years. Am in the point of deciding the ORM framework to use (or whether to use one at all). Can anyone with experience tell me whether orm frameworks are used in realworld applications. The problem i have in mind is this: The orm tool will generate for me tables and columns etc as i create and modify my entities. However, after the project has gone live and is in production, certain database changes will not be possible. Can this hinder the advancement of the project. If i had used a framework like ibatis for example, i know i would only need to adjust the sql statements based on the database changes. Can someone tell me whether ORM tools have survived the live environment. At my office, we use java based ERP that was done long ago and it was never done using any ORM framework. Regards. Josh

• Monitoring pthread context switching

  - by simon

  I would like to monitor the the context switching behavior in a multi-threaded pthread application. In other RTOSes(Micro C OS) I have been able to register a context switch callback for each thread in the application, and then log (or toggle a gpio) and watch the thread context switching in real time. This was a valuable tool for debugging the real time behavior and interaction of the multiple threads. My current environment is embedded linux utilizing the pthread api. Is there a way to montior each of the context switches?

• PySide using Style Sheets to change QtoolBox

  - by efi_ex

  I'm Wondering if somebody knows a better reference than the QT one for style sheets. I try to change the background of the content from a QToolBox but background-color only changes the header of the toolbox and the background of the content it reveals is left in a standard color. I then tried to change the bg of QWidget which worked but left me with problems now at Radiobuttons and Checkboxes, i also think changing QWidget isn't a good solution. The first picture is with Qt standard colors (this is a maya tool) the second when i change QWidget http://i.imgur.com/MNlSedx.png?1 http://i.imgur.com/wuplpmw.png?1

• What is the best software to capture full-screen 3h programming session in Windows?

  - by Hugo S Ferreira

  Hi, I'm planning a laboratorial experiment to assess behavior of groups when programming using some tools under study. For that, I'll need to capture their entire screen to disk. Mostly, what will be displayed is code, so I'm not to worried with image quality. However, it's paramount that the team is not able to stop the recording by accident, and the tool should be rebust enough to hold at least 3h of video. If possible, it would be nice for researchers in other rooms to "watch" the video as it is recording. Actually, this last requirement reminded me that I could use a VNC recording software, and install a VNC client in each laboratory computer. Anyway, what is your experience with this? Which software do you recommend? Thanks.

• Javascript draw dynamic line

  - by Ranch

  Hello, I'm looking for Javascript code for letting the user draw a line (on an image). Just as the line tool in Photoshop (for example): The user clicks on the image, drags the mouse (while the line between the start point and the mouse point is dynamically drawn on mouse drag). I would also need a callable function to send the page the start and end coordinates. I've found this very nice script for area selection: http://www.defusion.org.uk/code/javascript-image-cropper-ui-using-prototype-scriptaculous/ and I've found many script for drawing lines (and other shapes in JS), but could not find what I'm looking for. Thanks

• Is it actually possible to programmatically manage the state of an FTP server in IIS7?

  - by nbolton

  I'm able to manage FTP sites via the IIS manager, however, all attempts so far to manage the state of FTP sites using other means have failed, including: Using the IIS7 API (Microsoft.Web.Administration) Using WMI (with IIS6 compatibility enabled) Using the AppCmd tool in System32\inetsrv Related questions: Why am I unable to get Site.State for an FTP site, when using Microsoft.Web.Administration? Are there any workarounds I haven't tried? My objective is to manage (start/stop/query the state of) the FTP sites with C# code (as you can see from the 3 above attempted workarounds). When querying the FTP server state using WMI, it returns code 4, which means "Stopped", even though the site is definitely shown as running in IIS manager. AppCmd is useless, as it returns "Unknown" for FTP sites: c:\Windows\System32\inetsrv>appcmd list site SITE "Default Web Site" (id:1,bindings:http/*:80:,state:Stopped) SITE "Default FTP Site" (id:2,bindings:ftp/*:21:,state:Unknown)

• "from _json import..." - python

  - by RoseOfJericho

  Hello, all. I am inspecting the JSON module of python 3.1, and am currently in /Lib/json/scanner.py. At the top of the file is the following line: from _json import make_scanner as c_make_scanner There are five .py files in the module's directory: __init__ (two leading and trailing underscores, it's formatting as bold), decoder, encoder, scanner and tool. There is no file called "json". My question is: when doing the import, where exactly is "make_scanner" coming from? Yes, I am very new to Python!

• How can I get the GUID from a PDB file?

  - by thoughton

  Hello, Does anyone know how to get the GUID from a PDB file? I'm using Microsoft's Debug Interface Access SDK http://msdn.microsoft.com/en-us/library/f0756hat.aspx and getting E_PDB_INVALID_SIG when passing in the GUID i expect when trying to load the PDB. I'd just like to know the GUID of the PDB so I can be certain that it's mismatching and not just a PDB that's perhaps corrupted somehow. Is there a tool that can do this? I've tried dia2dump and dumpbin, but with no joy... Many thanks, thoughton.

• Is there a way to generate a gitignore from a makefile?

  - by Kinopiko

  I have a lot of files such as JavaScript, HTML, and even C and C header (.h) files which are automatically generated, so they appear in the makefile like myfile.js: myfile.js.tmpl etc. I want all of these target files to be ignored by the version control system. I am using git but this question is not git-specific. Is there a utility or a trick which exists to make the ignore file (like .gitignore) from a makefile? (If there isn't such a facility, I can make a script to create one, but before I do that I am just checking I haven't missed some obvious tool or method.)

• Android SDK and AVD manager will not run from Eclipse after upgrade to SDK 5 and ADT 0.9.6

  - by user303944

  Using Windows 7, 64 bit system. Prior to upgrade I was able to run "Android SDK and AVD manager" from Eclipse via a tool bar icon and menu option, both of which still exist. However now nothing happens when I try to run the manager. As a result I can't start an emulator from within Eclipse. When I use Eclipse to run an Android app, the first emulator I installed is automatically started. Using Windows Explorer, I can still run the manager from the SDK directory in which the update was applied (the update didn't change the location of the SDK). If I run the manager and start multiple emulators and then Run an app from Eclipse, it sees the emulators and allows me to choose one as before. This is a satisfactory work-around, but it would be nice if the manager were fully integrated into Eclipse as it was before.

• Why can I not install ASPNET MVC2 from the Web Platform Installer? (Error: "requires VS2008 SP1", bu

  - by Cheeso

  I went to http://www.asp.net/mvc/ to try to install ASP.NET MVC. I didn't know, but MVC is now at version 2. There's a nifty thing called the Microsoft "Web Platform Installer" (WPI) which basically is a small installer-driver tool that presents a menu of things I might want to install, to do web things on Windows. On the menu are things like ASPNET MVC2, but also Drupal, PHP, Joomla, and a bunch of other things. From http://www.asp.net/mvc/, when I click on the link that says "Install MVC", it resolves to http://go.microsoft.com/fwlink/?LinkID=185037, which then pops up the WPI. But Then! I get an error dialog that reads "Installing ASPNET MVC2 requires VS2008 SP1". But I know that I have VS2008 SP1. What gives?
