• LLBLGen Pro v3.5 has been released!

  - by FransBouma

  Last weekend we released LLBLGen Pro v3.5! Below the list of what's new in this release. Of course, not everything is on this list, like the large amount of work we put in refactoring the runtime framework. The refactoring was necessary because our framework has two paradigms which are added to the framework at a different time, and from a design perspective in the wrong order (the paradigm we added first, SelfServicing, should have been built on top of Adapter, the other paradigm, which was added more than a year after the first released version). The refactoring made sure the framework re-uses more code across the two paradigms (they already shared a lot of code) and is better prepared for the future. We're not done yet, but refactoring a massive framework like ours without breaking interfaces and existing applications is ... a bit of a challenge ;) To celebrate the release of v3.5, we give every customer a 30% discount! Use the coupon code NR1ORM with your order :) The full list of what's new: Designer Rule based .NET Attribute definitions. It's now possible to specify a rule using fine-grained expressions with an attribute definition to define which elements of a given type will receive the attribute definition. Rules can be assigned to attribute definitions on the project level, to make it even easier to define attribute definitions in bulk for many elements in the project. More information... Revamped Project Settings dialog. Multiple project related properties and settings dialogs have been merged into a single dialog called Project Settings, which makes it easier to configure the various settings related to project elements. It also makes it easier to find features previously not used  by many (e.g. type conversions) More information... Home tab with Quick Start Guides. To make new users feel right at home, we added a home tab with quick start guides which guide you through four main use cases of the designer. System Type Converters. Many common conversions have been implemented by default in system type converters so users don't have to develop their own type converters anymore for these type conversions. Bulk Element Setting Manipulator. To change setting values for multiple project elements, it was a little cumbersome to do that without a lot of clicking and opening various editors. This dialog makes changing settings for multiple elements very easy. EDMX Importer. It's now possible to import entity model data information from an existing Entity Framework EDMX file. Other changes and fixes See for the full list of changes and fixes the online documentation. LLBLGen Pro Runtime Framework WCF Data Services (OData) support has been added. It's now possible to use your LLBLGen Pro runtime framework powered domain layer in a WCF Data Services application using the VS.NET tools for WCF Data Services. WCF Data Services is a Microsoft technology for .NET 4 to expose your domain model using OData. More information... New query specification and execution API: QuerySpec. QuerySpec is our new query specification and execution API as an alternative to Linq and our more low-level API. It's build, like our Linq provider, on top of our lower-level API. More information... SQL Server 2012 support. The SQL Server DQE allows paging using the new SQL Server 2012 style. More information... System Type converters. For a common set of types the LLBLGen Pro runtime framework contains built-in type conversions so you don't need to write your own type converters anymore. Public/NonPublic property support. It's now possible to mark a field / navigator as non-public which is reflected in the runtime framework as an internal/friend property instead of a public property. This way you can hide properties from the public interface of a generated class and still access it through code added to the generated code base. FULL JOIN support. It's now possible to perform FULL JOIN joins using the native query api and QuerySpec. It's left to the developer to check whether the used target database supports FULL (OUTER) JOINs. Using a FULL JOIN with entity fetches is not recommended, and should only be used when both participants in the join aren't the target of the fetch. Dependency Injection Tracing. It's now possible to enable tracing on dependency injection. Enable tracing at level '4' on the traceswitch 'ORMGeneral'. This will emit trace information about which instance of which type got an instance of type T injected into property P. Entity Instances in projections in Linq. It's now possible to return an entity instance in a custom Linq projection. It's now also possible to pass this instance to a method inside the query projection. Inheritance fully supported in this construct. Entity Framework support The Entity Framework has been updated in the recent year with code-first support and a new simpler context api: DbContext (with DbSet). The amount of code to generate is smaller and the context simpler. LLBLGen Pro v3.5 comes with support for DbContext and DbSet and generates code which utilizes these new classes. NHibernate support NHibernate v3.2+ built-in proxy factory factory support. By default the built-in ProxyFactoryFactory is selected. FluentNHibernate Session Manager uses 1.2 syntax. Fluent NHibernate mappings generate a SessionManager which uses the v1.2 syntax for the ProxyFactoryFactory location Optionally emit schema / catalog name in mappings Two settings have been added which allow the user to control whether the catalog name and/or schema name as known in the project in the designer is emitted into the mappings.

• Backup options in SharePoint 2007

  - by sreejukg

  It is very important to make sure the server farm backup is taking properly, making sure that in case of any disaster, the administrator has the latest backup that can be used to restore. This articles addresses some of the options available for backup/restore in SharePoint 2007 Backup There are two options that can be utilized to take backup of SharePoint sites. Using SharePoint Central Administration website Using SharePoint central administration website, you can do backup/restore from user interface. Using central administration website you can back up the following · Server farm · Web application · Content databases Follow these steps to take backup of the server farm using central administration 1. Open Central administration website 2. Navigate to Operations -> Backup and Restore -> Perform a backup 3. Here you will have options to choose the item to back up. Select Farm (the top most item in the list) 4. Once you select the items to backup, click on “Continue to backup options” 5. Select “Full” as type of backup. 6. In the backup file location, enter the path where you need to store the backup. The path should be according to the UNC, for e.g. for c drive you may use \\server\c$\mybackupFolder 7. Click ok 8. Now you will be redirected to Backup and Restore Status page. This page shows the progress for the backup operation. You can use the refresh button to update the status of backup(this page will automatically refresh in every 30 seconds). Once completed you can find the files in the specified folder. Using STSADM website SharePoint comes with a STSADM command line tool. STSADM provides lot of administrative operations that can be performed on SharePoint 2007 sites. You can find STSADM command from the following location C:\Program Files\Common Files\Microsoft shared\web server extensions\12\bin (You may change the drive letter according to your installation) STSADM provides a method for performing the Office SharePoint Server 2007 administration tasks at the command line or by using batch files or scripts. STSADM provides access to operations not available by using the Central Administration site The general syntax for STSADM is as follows STSADM -operation Operation Name –parameter1 value1 –parameter2 value2 ……….. Using STSADM you can back up the following · Server farm · Web application · Content databases To perform any STSADM, operation you need to be a member of administrators group. Follow these steps to take backup of SharePoint server farm using STSADM tool. Note: make sure you are logged in to the computer where central administration website is installed. 1. Open the Command prompt (You should run command prompt with administrator privileges) 2. Change the working directory to C:\Program Files\Common Files\Microsoft shared\web server extensions\12\bin 3. Enter the command, then press enter Stsadm –o backup -directory <UNC path> -backupmethod full 4. You will get success / failure message once the command finishes. How to schedule the backup There is no option to schedule a backup using central administration site. Also there is no operation provided by STSADM to automate the backup. The farm administrators need to take backup in regular intervals. To achieve this, you can write a batch file that includes STSADM command to take full backup of the server. This batch file can be scheduled using windows task scheduler to execute in certain intervals. Sample of the batch file 1. Open notepad(or any other text editor) 2. Enter the following commands @echo off echo =============================================================== echo Back up the farm to <C:\backup> echo =============================================================== cd %COMMONPROGRAMFILES%\Microsoft Shared\web server extensions\12\BIN @echo off stsadm.exe -o backup -directory "<\backup>" -backupmethod full echo completed 3. Save the file with .bat extension You can schedule this batch file as you require. Other Options Using STSADM tool, you will be able to take backup for individual site collection. The syntax for this is stsadm -o backup -url <URL name for site collection> -filename <file name> [-overwrite] The explanations for the parameters are as follows. -url The url of the site collection you need to backup -filename The name of the backup file. E.g. c:\backup.bak -overwrite optional. Indicates if the filename specified exists, whether to overwrite or not. If you are creating the batch file for scheduling the backup for a site collection, you may need to specify the backup filename automatically created. It is an option that you can generate the filename with date so that you can keep backup for each day. e.g. The following commands can be utilized create a site collection backup. @echo off echo =============================================================== echo Back up the farm to <C:\backup> echo =============================================================== echo =============================================================== echo getting todays date to a variable echo =============================================================== @For /F "tokens=1,2,3 delims=/ " %%A in (‘Date /t’) do @( Set Day=%%A Set Month=%%B Set Year=%%C Set todayDate=%%C%%B%%A ) cd %COMMONPROGRAMFILES%\Microsoft Shared\web server extensions\12\BIN @echo off stsadm -o backup -url <sitecollection url> -filename \\ServerName\ShareName\Backup_%todayDate%.bak -overwrite echo completed To read more about backup STSADM operation, read this http://technet.microsoft.com/en-us/library/cc263441.aspx

• How long would it take to learn Python?

  - by Josh

  Hi all I have decided to take the time out after work to learn Python. Python appeals to me because at work (Web and eLearning Company), I have to follow out very repetitive tasks like delete all these tags, rename all these tasks and even more advanced repetive tasks. Additionally it would be good for me to get an understanding of Python first because of its fairly easy to learn syntax. How long would it take to learn the basics and go through these tutorials on Python (+ the Python tutorial)? I will only be spending 1 hour or so on it in the afternoons. http://openbookproject.net/thinkcs/python/english2e/index.html I have told my piano teacher I would like to take a month of learning piano to do this would this be adequate time? After this I may choose to learn PHP, because that is mainly what we use for web development at work. Thanks Josh

• Would a cut and paste coder ever get past a job interview?

  - by bigdave

  As a long time cut and paste coder I never committed much of the syntax of a language to memory. Even worse, I now use google to solve many of the coding problems which are of the type typically used in job interviews. This has greatly increased my productivity, the quality of the end result and stops me perpetuating the same bugs across all my code. However it means I don't actually remember the detail of the solution. For some reason in a job interview "I would look that up on google" does not seem to be the right answer. Am I better off in the interview to pass no comment on my coding style and simply pull out an iPad and produce the solution?

• Record and Play your WebLogic Console Tasks Like a DVR

  - by james.bayer

  Automation using WebLogic Scripting Tool Today on the Oracle internal mailing list for WebLogic Server questions someone asked how to automate the configuration of the thread model for WebLogic Server and they were having trouble with the jython scripting syntax.  I’ve previously written about this feature called Work Managers and the associated constraints.  However, I did not show how to automate the process of configuring this without the console using WebLogic Scripting Tool – the jython scripting automation environment abbreviated as WLST.  I’ve written some very basic introductions to WLST before and there is also an Oracle By Example on the subject, but this is a bit more advanced.  Fear not because there is a really easy-to-use feature of the WLS console that lets you “Record” user actions just like a DVR.  Using these recordings of the web-based console, you can easily create a script even if you are unfamiliar with the WLST syntax and API.  I’m a big fan of both DVR’s and automation as can be evidenced with this old Halloween picture taken during simpler times.  Obviously the Cast Away and The Big Labowski references show some age.  I was a big Tivo fan-boy back in the day and I still think it’s the best DVR. I strongly believe that WebLogic Scripting Tool (WLST) is an absolutely essential tool for automating administration tasks in anything beyond a development environment.  Even in development environments you can make a case that it makes sense to start the automation for environments downstream.  I promise you that once you start using it for any tasks that you do even semi-regularly, you won’t go back to clicking through the console.  It’s simply so much more efficient and less error-prone to run a script. Let’s say you need to create a Work Manager and MaxThreadsConstraint – the easy way to do it is configure it in the WLS console first while capturing the commands with a recording.  See the images for the simple steps – click to enlarge. Record Console Configurations to a File Review the Recordings and Make Slight Modifications In order to make the recorded .py file directly callable as a stand-alone script I added calls to the connect() and edit() functions at the beginning and calls to disconnect() and exit() at the end – otherwise the main section of the script was provided by the console recording.  Below is the resulting file I saved as d:/temp/wm.py connect('weblogic','welcome1', 't3://localhost:7001') edit() startEdit()   cd('/SelfTuning/wl_server') cmo.createMaxThreadsConstraint('MaxThreadsConstraint-0')   cd('/SelfTuning/wl_server/MaxThreadsConstraints/MaxThreadsConstraint-0') set('Targets',jarray.array([ObjectName('com.bea:Name=examplesServer,Type=Server')], ObjectName)) cmo.setCount(5) cmo.unSet('ConnectionPoolName')   cd('/SelfTuning/wl_server') cmo.createWorkManager('WorkManager-0') cd('/SelfTuning/wl_server/WorkManagers/WorkManager-0') set('Targets',jarray.array([ObjectName('com.bea:Name=examplesServer,Type=Server')], ObjectName))   cmo.setMaxThreadsConstraint(getMBean('/SelfTuning/wl_server/MaxThreadsConstraints/MaxThreadsConstraint-0')) cmo.setIgnoreStuckThreads(false)   activate() disconnect() exit() Run the Script If you want to test it be sure to delete the Work Manager and MaxThreadConstraint that you had previously created in the console.  Do something like the following - set up the environment and tell WLST to execute the script which happens in the first 2 lines, the rest doesn’t require any user input: D:\Oracle\wls11g\wlserver_10.3\samples\domains\wl_server\bin>setDomainEnv.cmd D:\Oracle\wls11g\wlserver_10.3\samples\domains\wl_server>java weblogic.WLST d:\temp\wm.py   Initializing WebLogic Scripting Tool (WLST) ...   Welcome to WebLogic Server Administration Scripting Shell   Type help() for help on available commands   Connecting to t3://localhost:7001 with userid weblogic ... Successfully connected to Admin Server 'examplesServer' that belongs to domain 'wl_server'.   Warning: An insecure protocol was used to connect to the server. To ensure on-the-wire security, the SSL port or Admin port should be used instead.   Location changed to edit tree. This is a writable tree with DomainMBean as the root. To make changes you will need to start an edit session via startEdit().   For more help, use help(edit)   Starting an edit session ... Started edit session, please be sure to save and activate your changes once you are done. Activating all your changes, this may take a while ... The edit lock associated with this edit session is released once the activation is completed. Activation completed Disconnected from weblogic server: examplesServer     Exiting WebLogic Scripting Tool.   Now if you go back and look in the console the changes have been made and we now have a compete script.  Of course there is a full MBean reference and you can learn the nuances of jython and WLST, but why not the WLS console do most of the work for you!  Happy scripting.

• Regular Expressions. Remember it, write it, test it.

  - by outcoldman

  I should say that I’m fan of regular expressions. Whenever I see the problem, which I can solve with Regex, I felt a burning desire to do it and going to write new test for new regex. Previously I had installed SharpDevelop Studio just for good regular expression tool in it (Why VS doesn’t have one?). But now I’m a little wiser, and for each Regex I write a separate test. I find it difficult to remember the syntax of regular expressions (I don’t write them very often); I always forget which character is responsible for the beginning of the line, etc. So I use external small and easy articles like this “Regular expressions - An introduction”. Now I want to show you little samples of regular expressions and want to show you how to test these samples. Read more... (redirect to http://outcoldman.ru)

• InvokeMember("click") webBrowser help

  - by Tom

  I am trying to automate a web page via the weBrowser and the button that i'm trying to click has no ID only a value. here's the html code for it: Accept I can't useGetElementById as the button has no ID. If I do HtmlElement goButton = this.webBrowser1.Document.All["Accept"]; goButton.InvokeMember("click"); My script stops showing a nullreference error highlighting the "goButton.InvokeMember("click");" If I do var inputControls = (from HtmlElement element in webBrowser1.Document.GetElementsByTagName("input") select element).ToList(); HtmlElement submitButton = inputControls.First(x = x.Name == "Accept"); My script give me an "Sequence contains no matching element" error at the "HtmlElement submitButton" line and sometimes the page has more than one of these Accept buttons, so I would need to be able to tell the difference between each one as well or at least be able to click on one without the script breaking Any help with this will be greatly appreciated

• SQL SERVER – Weekly Series – Memory Lane – #005

  - by pinaldave

  Here is the list of curetted articles of SQLAuthority.com across all these years. Instead of just listing all the articles I have selected a few of my most favorite articles and have listed them here with additional notes below it. Let me know which one of the following is your favorite article from memory lane. 2006 SQL SERVER – Cursor to Kill All Process in Database I indeed wrote this cursor and when I often look back, I wonder how naive I was to write this. The reason for writing this cursor was to free up my database from any existing connection so I can do database operation. This worked fine but there can be a potentially big issue if there was any important transaction was killed by this process. There is another way to to achieve the same thing where we can use ALTER syntax to take database in single user mode. Read more about that over here and here. 2007 Rules of Third Normal Form and Normalization Advantage – 3NF The rules of 3NF are mentioned here Make a separate table for each set of related attributes, and give each table a primary key. If an attribute depends on only part of a multi-valued key, remove it to a separate table If attributes do not contribute to a description of the key, remove them to a separate table. Correct Syntax for Stored Procedure SP Sometime a simple question is the most important question. I often see in industry incorrectly written Stored Procedure. Few writes code after the most outer BEGIN…END and few writes code after the GO Statement. In this brief blog post, I have attempted to explain the same. 2008 Switch Between Result Pan and Query Pan – SQL Shortcut Many times when I am writing query I have to scroll the result displayed in the result set. Most of the developer uses the mouse to switch between and Query Pane and Result Pane. There are few developers who are crazy about Keyboard shortcuts. F6 is the keyword which can be used to switch between query pane and tabs of the result pane. Interesting Observation – Use of Index and Execution Plan Query Optimization is a complex game and it has its own rules. From the example in the article we have discovered that Query Optimizer does not use clustered index to retrieve data, sometime non clustered index provides optimal performance for retrieving Primary Key. When all the rows and columns are selected Primary Key should be used to select data as it provides optimal performance. 2009 Interesting Observation – TOP 100 PERCENT and ORDER BY If you pull up any application or system where there are more than 100 SQL Server Views are created – I am very confident that at one or two places you will notice the scenario wherein View the ORDER BY clause is used with TOP 100 PERCENT. SQL Server 2008 VIEW with ORDER BY clause does not throw an error; moreover, it does not acknowledge the presence of it as well. In this article we have taken three perfect examples and demonstrated which clause we should use when. Comma Separated Values (CSV) from Table Column A Very common question – How to create comma separated values from a table in the database? The answer is also very common if we use XML. Check out this article for quick learning on the same subject. Azure Start Guide – Step by Step Installation Guide Though Azure portal has changed a quite bit since I wrote this article, the concept used in this article are not old. They are still valid and many of the functions are still working as mentioned in the article. I believe this one article will put you on the track to use Azure! Size of Index Table for Each Index – Solution Earlier I have posted a small question on this blog and requested help from readers to participate here and provide a solution. The puzzle was to write a query that will return the size for each index that is on any particular table. We need a query that will return an additional column in the above listed query and it should contain the size of the index. This article presents two of the best solutions from the puzzle. 2010 Well, this week in 2010 was the week of puzzles as I posted three interesting puzzles. Till today I am noticing pretty good interesting in the puzzles. They are tricky but for sure brings a great value if you are a database developer for a long time. I suggest you go over this puzzles and their answers. Did you really know all of the answers? I am confident that reading following three blog post will for sure help you enhance the experience with T-SQL. SQL SERVER – Challenge – Puzzle – Usage of FAST Hint SQL SERVER – Puzzle – Challenge – Error While Converting Money to Decimal SQL SERVER – Challenge – Puzzle – Why does RIGHT JOIN Exists 2011 DVM sys.dm_os_sys_info Column Name Changed in SQL Server 2012 Have you ever faced a situation where something does not work? When you try to fix it - you enjoy fixing it and started to appreciate the breaking changes. Well, this was exactly I felt yesterday. Before I begin my story, I want to candidly state that I do not encourage anybody to use * in the SELECT statement. Now the disclaimer is over – I suggest you read the original story – you will love it! Get Directory Structure using Extended Stored Procedure xp_dirtree Here is the question to you – why would you do something in SQL Server where you can do the same task in command prompt much easily. Well, the answer is sometime there are real use cases when we have to do such thing. This is a similar example where I have demonstrated how in SQL Server 2012 we can use extended stored procedure to retrieve directory structure.

• Unable to launch the ASP.NET Development server because port '1900' is in use.

  - by Shaul

  I don't know what has got into my computer today. I was developing just fine in VS 2008 and testing my ASP.NET web site on my development server. Then suddenly, out of the blue, I can't run my web site any more! As soon as I hit F5, the message appears: Unable to launch the ASP.NET Development server because port '1900' is in use. And it doesn't matter what port I change to, it's always in use! AAARRRGGGHH!!! I have tried: Changing the port number Restarting Visual Studio Rebooting my machine Installing IIS Clue: My IIS refuses to start. But I didn't have IIS installed when I was happily working earlier, so that is probably not the issue; it might just be highlighting something else... Thanks in advance... Update: after rebooting, IIS does start, but the problem here persists.

• WF4 - Display workflow design in asp.net and highlight an activity

  - by jikan_the_useless

  i need to display current status of a document approval workflow task in asp.net web page with a specific activity highlighted. i have seen the visual workflow tracker example (in wf&wcf samples) but i have two issues, 1-i have to render workflow in asp.net not in a wpf app. 2-i don't need to display current status with workflow running, all activities that need to highlighted are the one that require user input. e.g. "waiting for approval from department head" etc. if i could just convert the workflow xaml to jpg after highlighting a specific activity by activity id that created a bookmark and waiting to resume the bookmark it would do the work.

  I'm searching for a tool that will take a source directory and produce a single PDF containing the source code, preferably with syntax highlighting. I would like to read the PDF on my phone, in order to get familiar with a code-base, or just to see what I can learn by reading a lot of code. I will most often be reading Ruby. I would prefer if the tool ran on Linux. I don't mind paying for a tool if it is particularly good. Any suggestions?

• C#/.NET Little Wonders: Of LINQ and Lambdas - A Presentation

  - by James Michael Hare

  Once again, in this series of posts I look at the parts of the .NET Framework that may seem trivial, but can help improve your code by making it easier to write and maintain. The index of all my past little wonders posts can be found here. Today I’m giving a brief beginner’s guide to LINQ and Lambdas at the St. Louis .NET User’s Group so I thought I’d post the presentation here as well.  I updated the presentation a bit as well as added some notes on the query syntax.  Enjoy!

• Find the occurrence of word/character in SQL column with wildcard character - PATINDEX

  - by Vipin

  CharIndex and PatIndex both can be used to determine the presence of character or string within sql column data. Both returns the starting position of the first occurrence of the character/word within expression. However, one major difference between CharIndex and PatIndex is that later allows the use of wild card characters while searching for character or word within column data. Also, Patindex is useful for searching within Text datatype. Allowed wild card characters are % and _ . " % "  - use it for any number of characters " _ "  - use it for a single character. Syntax PATINDEX('%pattern%', string_expression) Note - it's mandatory to include pattern within %% characters. returns starting position of occurrence of pattern, if found. returns 0, if not found returns NULL , if either pattern or string_expression is null. Example SELECT fldname FROM tblUsers WHERE PatIndex('%v_pin%', fldname) > 0

• Learning language is enough to create average applications ?

  - by Freshblood

  Many books teach a programming language. However, knowing a specific language is not the same as knowning application or GUI design nor project layout. So, attempting to make an average application fails after learning a language. It is clear that knowing a language is not enough to make an application. If you agree with what I have said, why doesn't anyone mention this instead of teaching pure language syntax and features? Why books don't mention how to make a better application ?

• Inspiring problems to show off the importance of regular expressions?

  - by ragu.pattabi

  I am planning to give a presentation/demonstration on regular expressions at work to encourage young developers to add this powerful and important tool in their toolbox. Just teaching syntax doesn't cut it. I often see people say nice. After the presentation, they get on with their programming lives without ever thinking of using it mostly. I am raking my grey matter to come up with some solid examples, not just problems that matches 'cat' and 'cut'. I missed to note down the occasions of my regex enlightenments to use here. :^( Do you have some inspiring problems to share that could be solved with regex?

• A C# implementation of the CallStream pattern

  Dusan published this interesting post a couple of weeks ago about a novel JavaScript chaining pattern: http://dbj.org/dbj/?p=514 Its similar to many existing patterns, but the syntax is extraordinarily terse and it provides a new form of friction-free, plugin-less extensibility mechanism. Heres a JavaScript example from Dusans post: CallStream("#container") (find, "div") (attr, "A", 1) (css, "color", "#fff") ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Using HTMLAgility Pack to Extract Links

  - by Soham

  Hi Folks, Consider this simplest piece of code: using System; using System.Collections.Generic; using System.Linq; using System.Text; using HtmlAgilityPack; namespace WebScraper { class Program { static void Main(string[] args) { HtmlDocument doc = new HtmlDocument(); doc.LoadHtml("http://www.google.com"); foreach (HtmlNode link in doc.DocumentNode.SelectNodes("//a[@href]")) { } } } } This effectively doesnt do anything at all, and is copied/inspired from various other StackOverflow questions like this. When compiling this, there is a runtime error which says "Object reference not set to an instance of an object." highlighting the foreach line. I can't understand, why the environment has become irritable to this humble,innocent and useless piece of code. I would also like to know, does HTMLAgilityPack accept HTML classes as nodes?

• Can I do filename pattern matching in a bash script?

  - by Bob Bowden

  Can I do filename pattern matching in a bash script? "test" is a directory with the following files ... bob@bob-laptop:~/test$ ls exclude exclude1 exclude2 include1 include2 from the command line, if I want to exclude some of the files, I can do ... bob@bob-laptop:~/test$ echo !(exclude*) include1 include2 but, if I put that command in a script (named exclude) ... bob@bob-laptop:~/test$ cat exclude echo !(exclude*) when I execute it, I get an error ... bob@bob-laptop:~/test$ ./exclude ./exclude: line 1: syntax error near unexpected token (' ./exclude: line 1:echo !(exclude*)' I've tried every (I think) variation of escaping some, all or none of the special characters and I still get an error. What am I missing here? If I can't do this, would someone please be so kind as to explain why?

• emacs elisp buffer not running font lock mode until opened by user

  - by jacob

  My problem is I am opening a buffer using (set-buffer (find-tag-noselect (current-word))) and then I try to copy some text out of that buffer. The text that I get back has only the properties (fontified nil). find-tag-noselect automatically opens the buffer found in the TAGS file but it seems it does not run the font lock mode over it. When I manually switch to this buffer after it has been opened and then run the function again when it copies the text it has all the correct text properties attached. So what do I need to do to have this buffer completely initialized so that the correct syntax highlighting will be copied in?

• Python 3.4 adds re.fullmatch()

  - by Jan Goyvaerts

  Python 3.4 does not bring any changes to its regular expression syntax compared to previous 3.x releases. It does add one new function to the re module called fullmatch(). This function takes a regular expression and a subject string as its parameters. It returns True if the regular expression can match the string entirely. It returns False if the string cannot be matched or if it can only be matched partially. This is useful when using a regular expression to validate user input. Do note that fullmatch() will return True if the subject string is the empty string and the regular expression can find zero-length matches. A zero-length match of a zero-length string is a complete match. So if you want to check whether the user entered a sequence of digits, use \d+ rather than \d* as the regex.

• I am trying to build libmtp 1.1.14 but I cannot fix this error

  - by Kristoffer

  I have run this in a terminal. git clone git://libmtp.git.sourceforge.net/gitroot/libmtp/libmtp cd libmtp ./autogen.sh (answering yes to all questions) But when I try to run the ./configure --prefix=/usr/ I get this error: checking whether to build static libraries... yes ./configure: line 11739: AC_LIB_PREPARE_PREFIX: command not found ./configure: line 11740: AC_LIB_RPATH: command not found ./configure: line 11745: syntax error near unexpected token `iconv' ./configure: line 11745: ` AC_LIB_LINKFLAGS_BODY(iconv)' I have built and installed the libiconv from here. I do not know what to do, been trying for a few hours but I am pretty noob to Linux. How can i fix this? The lines 11739 to 11745 in the configure file looks like this: AC_LIB_PREPARE_PREFIX AC_LIB_RPATH AC_LIB_LINKFLAGS_BODY(iconv)
