  • Set attribute to all child elements via xsl:choose

    - by Camal
    Hi, assuming I got following XML file : <?xml version="1.0" encoding="ISO-8859-1" ?> <MyCarShop> <Car gender="Boy"> <Door>Lamborghini</Door> <Key>Skull</Key> </Car> <Car gender="Girl"> <Door>Normal</Door> <Key>Princess</Key> </Car> </MyCarShop> I want to perform a transformation so the xml looks like this : <?xml version="1.0" encoding="ISO-8859-1" ?> <MyCarShop> <Car gender="Boy"> <Door color="blue">Lamborghini</Door> <Key color="blue">Skull</Key> </Car> <Car gender="Girl"> <Door color="red">Normal</Door> <Key color="red">Princess</Key> </Car> </MyCarShop> So I want to add a color attribut to each subelement of Car depending on the gender information. I came up with this XSLT but it doesnt work : <?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl" > <xsl:output method="xml" indent="yes"/> <!--<xsl:template match="@* | node()"> <xsl:copy> <xsl:apply-templates select="@* | node()"/> </xsl:copy> </xsl:template>--> <xsl:template match="/"> <xsl:element name="MyCarShop"> <xsl:attribute name="version">1.0</xsl:attribute> <xsl:apply-templates/> </xsl:element> </xsl:template> <xsl:template match="Car"> <xsl:element name="Car"> <xsl:apply-templates/> </xsl:element> </xsl:template> <xsl:template match="Door"> <xsl:element name="Door"> <xsl:attribute name="ViewSideIndicator"> <xsl:choose> <xsl:when test="gender = 'Boy' ">Front</xsl:when> <xsl:when test="gender = 'Girl ">Front</xsl:when> </xsl:choose> </xsl:attribute> </xsl:element> </xsl:template> <xsl:template match="Key"> <xsl:element name="Key"> <xsl:apply-templates/> </xsl:element> </xsl:template> </xsl:stylesheet> Does anybody know what might be wrong ?

  • Elements of website don't work in IE

    - by mjcuva
    On the site I'm working on for my high school basketball team, certain elements don't work in Internet Explorer. The site is hermantownbasketball.com. The boys basketball sidebar should have nested drop down menus, one when you mouse over the team, such as "High School" and then another when you mouse over the grade under the team, such as 9th grade. This works perfectly fine in chrome, however, I can't get it to work in any version of Internet Explorer. Below is the part of the html and the corresponding css I am using. Unfortunately, I don't know enough css to know which part of my code IE doesn't like or how to fix it. Any help is greatly appreciated! HTML <span class = "boyItem"> <h3>High School</h3> <li class="group"> <h4>9th Grade</h4> <div class = "nested">Schedule</div> <div class = "nested">Events</div> <div class ="nested">Forms</div> <div class ="nested">Calendar</div> </li> <li class="group"> <h4>JV/Varsity</h4> <div class = "nested">Schedule</div> <div class = "nested">Events</div> <div class = "nested">Forms</div> <div class = "nested">Calendar</div> </li> </span> /* Creates the box around the title for each boy section. */ .boyItem h3 { background:#1C23E8; color:#EFFA20; padding-right:2px; padding:10px; font-size:18px; margin-left:-30px; margin-top:-10px; } ###CSS .boyItem h3:hover { background:#2A8FF5; } /* Prevents the boy sub-sections from being visable */ .boyItem li h4 { position: absolute; left:-9999px; font-size:15px; list-style-type:none;} /* Shows the boy sub-sections when user mouses over the section title. */ .boyItem:hover li h4 { position:relative; left:10px; background:#1C23E8; color:#EFFA20; padding-left:20px; padding:5px; } .boyItem:hover li h4:hover { background:#2A8FF5;} .nested { position:absolute; left:-9999px; background:#352EFF; color:#EFFA20; padding-right:2px; padding:4px; font-size:14px; margin:2px; margin-left:30px; margin-top:0px; margin-right:0px; margin-bottom:-2px;} .group:hover .nested {position:relative; left:0px; } .group:hover .nested:hover { background:#2A8FF5}

  • Silverlight Cream for April 29, 2010 -- #851

    - by Dave Campbell
    In this Issue: Carlos Figueira(-2-), Subodh Pushpak, Gergely Orosz, John Papa, Mike Snow(-2-), Rishi, Tim Heuer, Stefan Olson, and David Anson. Shoutouts: Josh Holmes blogged about a cool app the City of Miami has up: Miami 311: Built on Windows Azure Gergely Orosz reports on the state of a bug he found pre SL4: Silverlight 4 still displays large elements incorrectly Laura Foy and Charlie Kindel discuss WP7 on Channel 9: Windows Phone 7 Developer Tools Refresh Announced Charlie Kindel has an announcement, good instructions, and what's new notes on the Windows Phone Developer Tools CTP Refresh! Tim Heuer mentioned the workaround for this in his post (below), but I thought you might like to read Brandon Watson's debrief of what it's all about: Signed Assemblies Bug in the Windows Phone Tools CTP Refresh Laurent Bugnion posted about interrelations between versions of Blend and WP7 code... read it closely: Be careful when installing the Blend Windows Phone 7 Add-In From SilverlightCream.com: Consuming REST/POX services in Silverlight 4 Carlos Figueira has a pair of posts up about consuming services in Silverlight 4. This first one is about consuming REST/POX services. He provides a Service Contract that can be used with either and the full project code is available as well. Consuming REST/JSON services in Silverlight 4 In the second post, Carlos Figueira provides the code to allow WCF and Silverlight 4 to consume strongly-typed REST/JSON... and again, all the code is available. Silverlight and WCF caching Subodh Pushpak has a post up discussing caching in WCF, and has code demonstrating turning caching on at run-time. Detecting Silverlight Version Installed Gergely Orosz said it right when he said "Detecting the Silverlight version installed on a client machine isn’t entirely straightforward." ... and after reading this post, if you take the link to his ScottLogic blog, you'll get a full break-out of how it's done. Silverlight TV 22: Tim Heuer on Extending the SMF It's Thursday, and that means Silverlight TV! ... this week, John Papa has on Tim Heuer who has always been out there pushing media... and he's talking about SMF or Silverlight Media Framework for the uninitiated, and also extending it. Silverlight Tip of the Day #7 – Localized Resources Mike Snow has Tip Number 7 up and it's about localization... good end-to-end discussion and demonstration. Just thought I should use that to prove to my daughter that the tatoo she had put on the back of her neck actually reads "Eat More Broccoli" :) Silverlight Tip of the Day #8 – Detecting Alt, Shift, Control, Window & Apple Keys Combinations I just realized Mike Snow's site logo reads "Silverlight Tips of the Day" (bolding mine) ... that answers why I'm seeing more than one -- sorry Mike, couldn't pass it up :) ... Mike's second tip today and number 8 in the series is on detecting all the mouse button and ctl/alt/shift combinations in Silverlight. nRoute: More Wholesomeness, with SL 4 and .NET 4.0 Rishi has a post up announcing a new nRoute release for Silverlight 4 and .NET 4.0 He's tweaked the code to take advantages of enhancements in the new platforms, so check it out. Windows Phone 7 Developer Tools April 2010 Refresh Booya... Tim Heuer announced the release of the next drop in the WP7 tools ... dang wish I was at home today :) ... be sure to read the post for info such as the notes about Authenticode Assemblies and the release notes. Updates to Silverlight Multi-binding support Stefan Olson points up a SL4 change to Multi-binding support that he had previously blogged about. He shows the previous non-working example, and what you have to do to make it work now. Using XAML to create a custom wallpaper image for your mobile device David Anson has a solution for those pesky lost devices, and let me go on the record right now saying if anyone finds a WP7 phone laying around, just call me, it's mine :) [think that'd work??] ... ok, David's solution is a WPF app "MobileDeviceHomeScreenMaker" that you get the info set and it produces a png you then put on your device.

  • Correlate GROUP BY and LEFT JOIN on multiple criteria to show latest record?

    - by Sunbird
    In a simple stock management database, quantity of new stock is added and shipped until quantity reaches zero. Each stock movement is assigned a reference, only the latest reference is used. In the example provided, the latest references are never shown, the stock ID's 1,4 should have references charlie, foxtrot respectively, but instead show alpha, delta. How can a GROUP BY and LEFT JOIN on multiple criteria be correlated to show the latest record? http://sqlfiddle.com/#!2/6bf37/107 CREATE TABLE stock ( id tinyint PRIMARY KEY, quantity int, parent_id tinyint ); CREATE TABLE stock_reference ( id tinyint PRIMARY KEY, stock_id tinyint, stock_reference_type_id tinyint, reference varchar(50) ); CREATE TABLE stock_reference_type ( id tinyint PRIMARY KEY, name varchar(50) ); INSERT INTO stock VALUES (1, 10, 1), (2, -5, 1), (3, -5, 1), (4, 20, 4), (5, -10, 4), (6, -5, 4); INSERT INTO stock_reference VALUES (1, 1, 1, 'Alpha'), (2, 2, 1, 'Beta'), (3, 3, 1, 'Charlie'), (4, 4, 1, 'Delta'), (5, 5, 1, 'Echo'), (6, 6, 1, 'Foxtrot'); INSERT INTO stock_reference_type VALUES (1, 'Customer Reference'); SELECT stock.id, SUM(stock.quantity) as quantity, customer.reference FROM stock LEFT JOIN stock_reference AS customer ON stock.id = customer.stock_id AND stock_reference_type_id = 1 GROUP BY stock.parent_id

  • retrieve value from hashtable with clone of key; C#

    - by Johnny
    I would like to know if there is any possible way to retrieve an item from a hashtable using a key that is identical to the actual key, but a different object. I understand why it is probably not possible, but I would like to see if there is any tricky way to do it. My problem arises from the fact that, being as stupid as I am, I created hashtables with int[] as the keys, with the integer arrays containing indices representing spatial position. I somehow knew that I needed to create a new int[] every time I wanted to add a new entry, but neglected to think that when I generated spatial coordinate arrays later they would be worthless in retrieving the values from my hashtables. Now I am trying to decide whether to rearrange things so that I can store my values in ArrayLists, or whether to search through the list of keys in the Hashtable for the one I need every time I want to get a value, neither of the options being very cool. Unless of course there is a way to get //1 to work like //2! Thanks in advance. static void Main(string[] args) { Hashtable dog = new Hashtable(); //1 int[] man = new int[] { 5 }; dog.Add(man, "hello"); int[] cat = new int[] { 5 }; Console.WriteLine(dog.ContainsKey(cat)); //false //2 int boy = 5; dog.Add(boy, "wtf"); int kitten = 5; Console.WriteLine(dog.ContainsKey(kitten)); //true; }

  • Hide All But First Matching Element

    - by Batfan
    I am using jquery to sort through multiple paragraphs. Currently I have it set to show only paragraphs that start with a current letter. But now, I would like to consolidate further. If the text between the paragraph tags has multiple instances, I would like all but the first hidden. This is what I have so far but, it is not working. var letter = '<?php echo(strlen($_GET['letter']) == 1) ? $_GET['letter'] : ''; ?>' function finish(){ jQuery('p').each(function(){ if(jQuery(this).text().substr(0,1).toUpperCase() == letter){ jQuery(this).addClass('current-series'); jQuery(this).html(letter + '<span class="hidden">'+jQuery(this).text().slice(1)+ '</span>'); } else{ jQuery(this).hide();} }) } Update: Sorry guys, I know this is kind of hard to explain. Here's a basic example: The selected letter is B The values returned are: Ball Ball Ball Boy Brain Bat Bat Each of these values is in a paragraph tag. Is there a way to consolidate to this? Ball Boy Brain Bat

  • OS X: How to show all files in chooser dialogs

    - by Stabledog
    On OS X 10.5 and 10.6 at least, the command to enable all files in Finder only affects Finder Windows -- the "/File /Open" dialogs on applications still show a limited set of files, ignoring nearly all the Unix stuff. Is there a setting which enables ALL file dialogs of ALL types to show ALL files? I really am a big boy and promise not to harm them! :)

  • iTunes 9 not sorting albums by track order consistently

    - by joshhunt
    I have my iTunes library set to sort by music by Artist, then album (). For most of my albums this will also sort the albums in the correct track listing order (using the track number tag). Except for one album: As you can see, "The Boy Who Knew Too Much" seems to sort erratically. Why is this happening and how can I fix it?

  • BDD IS Different to TDD

    - by Liam McLennan
    One of this morning’s sessions at Alt.NET 2010 discussed BDD. Charlie Pool expressed the opinion, which I have heard many times, that BDD is just a description of TDD done properly. For me, the core principles of BDD are: expressing behaviour in terms that show the value to the system actors Expressing behaviours / scenarios in a format that clearly separates the context, the action and the observations. If we go back to Kent Beck’s TDD book neither of these elements are mentioned as being core to TDD. BDD is an evolution of TDD. It is a specialisation of TDD, but it is not the same as TDD. Discussing BDD, and building specialised tools for BDD, is valuable even though the difference between BDD and TDD is subtle. Further, the existence of BDD does not mean that TDD is obsolete or invalidated.

  • International Radio Operators Alphabet in F# &amp; Silverlight &ndash; Part 1

    - by MarkPearl
    So I have been delving into F# more and more and thought the best way to learn the language is to write something useful. I have been meaning to get some more Silverlight knowledge (up to now I have mainly been doing WPF) so I came up with a really simple project that I can actually use at work. Simply put – I often get support calls from clients wanting new activation codes. One of our main app’s was written in VB6 and had its own “security” where it would require about a 45 character sequence for it to be activated. The catch being that each time you reopen the program it would require a different character sequence, which meant that when we activate clients systems we have to do it live! This involves us either referring them to a website, or reading the characters to them over the phone and since nobody in the office knows the IROA off by heart we would come up with some interesting words to represent characters… 9 times out of 10 the client would type in the wrong character and we would have to start all over again… with this app I am hoping to reduce the errors of reading characters over the phone by treating it like a ham radio. My “Silverlight” application will allow for the user to input a series of characters and the system will then generate the equivalent IROA words… very basic stuff e.g. Character Input – abc Words Generated – Alpha Bravo Charlie After listening to Anders Hejlsberg on Dot Net Rocks Show 541 he mentioned that he felt many applications could make use of F# but in an almost silo basis – meaning that you would write modules that leant themselves to Functional Programming in F# and then incorporate it into a solution where the front end may be in C# or where you would have some other sort of glue. I buy into this kind of approach, so in this project I will use F# to do my very intensive “Business Logic” and will use Silverlight/C# to do the front end. F# Business Layer I am no expert at this, so I am sure to get some feedback on way I could improve my algorithm. My approach was really simple. I would need a function that would convert a single character to a string – i.e. ‘A’ –> “Alpha” and then I would need a function that would take a string of characters, convert them into a sequence of characters, and then apply my converter to return a sequence of words… make sense? Lets start with the CharToString function let CharToString (element:char) = match element.ToString().ToLower() with | "1" -> "1" | "5" -> "5" | "9" -> "9" | "2" -> "2" | "6" -> "6" | "0" -> "0" | "3" -> "3" | "7" -> "7" | "4" -> "4" | "8" -> "8" | "a" -> "Alpha" | "b" -> "Bravo" | "c" -> "Charlie" | "d" -> "Delta" | "e" -> "Echo" | "f" -> "Foxtrot" | "g" -> "Golf" | "h" -> "Hotel" | "i" -> "India" | "j" -> "Juliet" | "k" -> "Kilo" | "l" -> "Lima" | "m" -> "Mike" | "n" -> "November" | "o" -> "Oscar" | "p" -> "Papa" | "q" -> "Quebec" | "r" -> "Romeo" | "s" -> "Sierra" | "t" -> "Tango" | "u" -> "Uniform" | "v" -> "Victor" | "w" -> "Whiskey" | "x" -> "XRay" | "y" -> "Yankee" | "z" -> "Zulu" | element -> "Unknown" Quite simple, an element is passed in, this element is them converted to a lowercase single character string and then matched up with the equivalent word. If by some chance a character is not recognized, “Unknown” will be returned… I know need a function that can take a string and can parse each character of the string and generate a new sequence with the converted words… let ConvertCharsToStrings (s:string) = s |> Seq.toArray |> Seq.map(fun elem -> CharToString(elem)) Here… the Seq.toArray converts the string to a sequence of characters. I then searched for some way to parse through every element in the sequence. Originally I tried Seq.iter, but I think my understanding of what iter does was incorrect. Eventually I found Seq.map, which applies a function to every element in a sequence and then creates a new collection with the adjusted processed element. It turned out to be exactly what I needed… To test that everything worked I created one more function that parsed through every element in a sequence and printed it. AT this point I realized the the Seq.iter would be ideal for this… So my testing code is below… let PrintStrings items = items |> Seq.iter(fun x -> Console.Write(x.ToString() + " ")) let newSeq = ConvertCharsToStrings("acdefg123") PrintStrings newSeq Console.ReadLine()   Pretty basic stuff I guess… I hope my approach was right? In Part 2 I will look into doing a simple Silverlight Frontend, referencing the projects together and deploying….

  • LINQ und ArcObjects

    - by Marko Apfel
    LINQ und ArcObjects Motivation LINQ1 (language integrated query) ist eine Komponente des Microsoft .NET Frameworks seit der Version 3.5. Es erlaubt eine SQL-ähnliche Abfrage zu verschiedenen Datenquellen wie SQL, XML u.v.m. Wie SQL auch, bietet LINQ dazu eine deklarative Notation der Problemlösung - d.h. man muss nicht im Detail beschreiben wie eine Aufgabe, sondern was überhaupt zu lösen ist. Das befreit den Entwickler abfrageseitig von fehleranfälligen Iterator-Konstrukten. Ideal wäre es natürlich auf diese Möglichkeiten auch in der ArcObjects-Programmierung mit Features zugreifen zu können. Denkbar wäre dann folgendes Konstrukt: var largeFeatures = from feature in features where (feature.GetValue("SHAPE_Area").ToDouble() > 3000) select feature; bzw. dessen Äquivalent als Lambda-Expression: var largeFeatures = features.Where(feature => (feature.GetValue("SHAPE_Area").ToDouble() > 3000)); Dazu muss ein entsprechender Provider zu Verfügung stehen, der die entsprechende Iterator-Logik managt. Dies ist leichter als man auf den ersten Blick denkt - man muss nur die gewünschten Entitäten als IEnumerable<IFeature> liefern. (Anm.: nicht wundern - die Methoden GetValue() und ToDouble() habe ich nebenbei als Erweiterungsmethoden deklariert.) Im Hintergrund baut LINQ selbständig eine Zustandsmaschine (state machine)2 auf deren Ausführung verzögert ist (deferred execution)3 - d.h. dass erst beim tatsächlichen Anfordern von Entitäten (foreach, Count(), ToList(), ..) eine Instanziierung und Verarbeitung stattfindet, obwohl die Zuweisung schon an ganz anderer Stelle erfolgte. Insbesondere bei mehrfacher Iteration durch die Entitäten reibt man sich bei den ersten Debuggings verwundert die Augen wenn der Ausführungszeiger wie von Geisterhand wieder in die Iterator-Logik springt. Realisierung Eine ganz knappe Logik zum Konstruieren von IEnumerable<IFeature> lässt sich mittels Durchlaufen eines IFeatureCursor realisieren. Dazu werden die einzelnen Feature mit yield ausgegeben. Der einfachen Verwendung wegen, habe ich die Logik in eine Erweiterungsmethode GetFeatures() für IFeatureClass aufgenommen: public static IEnumerable GetFeatures(this IFeatureClass featureClass, IQueryFilter queryFilter, RecyclingPolicy policy) { IFeatureCursor featureCursor = featureClass.Search(queryFilter, RecyclingPolicy.Recycle == policy); IFeature feature; while (null != (feature = featureCursor.NextFeature())) { yield return feature; } //this is skipped in unit tests with cursor-mock if (Marshal.IsComObject(featureCursor)) { Marshal.ReleaseComObject(featureCursor); } } Damit kann man sich nun ganz einfach die IEnumerable<IFeature> erzeugen lassen: IEnumerable features = _featureClass.GetFeatures(RecyclingPolicy.DoNotRecycle); Etwas aufpassen muss man bei der Verwendung des "Recycling-Cursors". Nach einer verzögerten Ausführung darf im selben Kontext nicht erneut über die Features iteriert werden. In diesem Fall wird nämlich nur noch der Inhalt des letzten (recycelten) Features geliefert und alle Features sind innerhalb der Menge gleich. Kritisch würde daher das Konstrukt largeFeatures.ToList(). ForEach(feature => Debug.WriteLine(feature.OID)); weil ToList() schon einmal durch die Liste iteriert und der Cursor somit einmal durch die Features bewegt wurde. Die Erweiterungsmethode ForEach liefert dann immer dasselbe Feature. In derartigen Situationen darf also kein Cursor mit Recycling verwendet werden. Ein mehrfaches Ausführen von foreach ist hingegen kein Problem weil dafür jedes Mal die Zustandsmaschine neu instanziiert wird und somit der Cursor neu durchlaufen wird – das ist die oben schon erwähnte Magie. Ausblick Nun kann man auch einen Schritt weiter gehen und ganz eigene Implementierungen für die Schnittstelle IEnumerable<IFeature> in Angriff nehmen. Dazu müssen nur die Methode und das Property zum Zugriff auf den Enumerator ausprogrammiert werden. Im Enumerator selbst veranlasst man in der Reset()-Methode das erneute Ausführen der Suche – dazu übergibt man beispielsweise ein entsprechendes Delegate in den Konstruktur: new FeatureEnumerator( _featureClass, featureClass => featureClass.Search(_filter, isRecyclingCursor)); und ruft dieses beim Reset auf: public void Reset() {     _featureCursor = _resetCursor(_t); } Auf diese Art und Weise können Enumeratoren für völlig verschiedene Szenarien implementiert werden, die clientseitig restlos identisch nach obigen Schema verwendet werden. Damit verschmelzen Cursors, SelectionSets u.s.w. zu einer einzigen Materie und die Wiederverwendbarkeit von Code steigt immens. Obendrein lässt sich ein IEnumerable in automatisierten Unit-Tests sehr einfach mocken - ein großer Schritt in Richtung höherer Software-Qualität.4 Fazit Nichtsdestotrotz ist Vorsicht mit diesen Konstrukten in performance-relevante Abfragen geboten. Dadurch dass im Hintergrund eine Zustandsmaschine verwalten wird, entsteht einiges an Overhead dessen Verarbeitung zusätzliche Zeit kostet - ca. 20 bis 100 Prozent. Darüber hinaus ist auch das Arbeiten ohne Recycling schnell ein Performance-Gap. Allerdings ist deklarativer LINQ-Code viel eleganter, fehlerfreier und wartungsfreundlicher als das manuelle Iterieren, Vergleichen und Aufbauen einer Ergebnisliste. Der Code-Umfang verringert sich erfahrungsgemäß im Schnitt um 75 bis 90 Prozent! Dafür warte ich gerne ein paar Millisekunden länger. Wie so oft muss abgewogen werden zwischen Wartbarkeit und Performance - wobei für mich Wartbarkeit zunehmend an Priorität gewinnt. Zumeist ist sowieso nicht der Code sondern der Anwender die Bremse im Prozess.

    I have no idea why this isn't working. I've tried creating map rules and then rewritng and redirecting the url. I've tried just redirecting it with a simple rewrite rule and no matter what, the only time I can get it to work is if I set the match url to match this regex .*. I'm trying to redirect webmail.example.com to mail.example.com. Seemed like it would have taken but a couple seconds; boy was I wrong. I'm thinking I must be doing something wrong with the regex, but I'm not sure what as when I test it it seems to work fine. <rule name="webmail" patternSyntax="ECMAScript" stopProcessing="true"> <match url=".*webmail.*" /> <conditions logicalGrouping="MatchAll" trackAllCaptures="false"> </conditions> <action type="Redirect" url="https://mail.example.com:8000" appendQueryString="false" logRewrittenUrl="true" /> </rule> Thanks

    Many geeks know the pain of losing a home office when a new baby comes along, but not many of them go to such lengths to miniaturize their offices like this. With a little ingenuity an entire home office now fits inside a heavily modified IKEA work table. Ian, an IKEAHacker reader and Los Angeles area geek, explains the motivation for the build: I had to surrender my home office to make room for my new baby boy ;) I took an Ikea stainless steel kitchen “work table”, some Ikea computer tower desk trays, two steel tabletops, and two grated steel shelves to make an “office” that I could pack away into a closet. Hit up the link below to check out the full photo set, the build includes quite a few clever design choices like mounted monitors, a ventilation system, and more.

  • Redirect a URL to another URL with IIS 7.5

    - by Jason White
    I have no idea why this isn't working. I've tried creating map rules and then rewriting and redirecting the URL. I've tried just redirecting it with a simple rewrite rule and no matter what, the only time I can get it to work is if I set the match URL to match this regex .*. I'm trying to redirect webmail.example.com to mail.example.com. Seemed like it would have taken but a couple seconds; boy was I wrong. I'm thinking I must be doing something wrong with the regex, but I'm not sure what as when I test it it seems to work fine. <rule name="webmail" patternSyntax="ECMAScript" stopProcessing="true"> <match url=".*webmail.*" /> <conditions logicalGrouping="MatchAll" trackAllCaptures="false"> </conditions> <action type="Redirect" url="https://mail.example.com:8000" appendQueryString="false" logRewrittenUrl="true" /> </rule>

  • Choice of Input / music / graphics libraries for an indie game - what factors should I consider?

    - by RusselMeMan
    I was wondering which tools (grapics-sound-input libraries, game engine libraries) that the following indie games used: Braid Superbrothers: S&S Super Meat Boy Limbo Fez (I know this one is XNA) Also, what is in common use in production games? My guess for game development in C++ is: -DirectX is most common for  Windows games -SDL or SDL+OpenGL is most common for  Linux games -OpenGL + Apple APIs are most common for OSX development What do most indie game projects use? If I wanted to casually build my own game for fun in C++ with the idea of possibly releasing it to Steam or something someday, is there anything I should be concerned about if I make it with DirectX for music/sound/input and build my own game engine? Thanks!

  • How do I implement Unreal-like object serialization?

    - by MrWiggels
    Recently, I've been working on the core of my engine, and as I'm moving forward I find myself developing throwaway code to read files and simple data into the engine. This got me thinking about how I should implement a file management system. After a bit of googleing I came across the Unreal Package format, and boy does it look like the perfect one. I think it's good because the way how it allows you to separate different assets into different packages and allow something like a level to reference the different packages. I was just wondering, is this possible with C#? Because the built-in serialization API in .NET does not seem to support any form of this, only reading and writing to a single file.

  • Handheld device software - Handheld tuners?

    - by NathanH
    Hey I've been looking around and really don't understand what software some of these company's use for their handheld devices. I've used a lot of Handheld Tuners (Cobb Accessport, Diablo Sport). I've gotten more and more knowledgable of programming and I'm really wanting to understand what software they use on these devices to have a graphical interface. And to hold all the files to flash over to the ecu. I'm just unsure how you would get basically all the components to work together (screen, buttons, memory) without having drivers installed. I could be totally wrong here on using the term drivers, but that's what I would like some help to get more knowledge on (only thing I've really found is making a handheld game boy from scratch,but that was using a emulator.). I've tried looking it up but can't really find a good write up or explanation anywhere I look. Just really would like to put a little device together and have a simple user interface and work from there. Thanks, Nathan
