  • installer hanging during .net 4.5 framework install

    - by Niall Collins
    I am having trouble installing Visual studio 2012 Premium Edition. I kick off the installer for it but it hangs when installing .net 4.5 framework. I have left it for hours but there is no progression in the progress bar. I have downloaded the .net 4.5 framework separately and tried to install that from msi but that also hangs similarly. The only way to kill it is by killing the process. Any ideas how I could resolve this issue, or what I need to do to trouble shoot it further? Any tips?

  • XSLT: look for a word and it's context

    - by farhad
    Hello! I need to search a word and it's context into an xml. For example <line>hello world, my name is farhad and i'm having trouble with xslt</line> looking for 'and', context of 3 words: <line>hello world, my <span class="context">name is farhad <span class="word">and</span> i'm having</span> trouble with xslt</line> How can i do? I wrote some xslt to find the word, but i can't go back 3 words to set span. This is my xslt: <xsl:variable name="delimiters">[,.;!?\s"()]+</xsl:variable> <xsl:template match="/"> <xsl:apply-templates select="//line"/> </xsl:template> <xsl:template match="line"> <line> <xsl:for-each select="tokenize(.,'\s')"> <xsl:choose> <!-- se l'ultimo carattere è di punteggiatura, prendo la sottostringa senza la punteggiatura --> <xsl:when test="compare(replace(.,$delimiters,'$1'),'red') = 0"> <span class="word"> <xsl:value-of select="."/> </span> </xsl:when> <xsl:otherwise> <xsl:value-of select="."/> <xsl:choose> <xsl:when test="position()=last()"> <xsl:text></xsl:text> </xsl:when> <xsl:otherwise> <xsl:text> </xsl:text> </xsl:otherwise> </xsl:choose> </xsl:otherwise> </xsl:choose> </xsl:for-each> </line><xsl:text> </xsl:text> </xsl:template> This is an example xml: http://pastebin.com/eAVM9CDQ . I have to search for context also on preceding tags, for example: <line>hello world,</line> <line>my name</line> <line>is farhad </line> <line>and i'm having</line> <line>trouble with xslt</line> so, looking for 'and', context of 3 words: <line>hello world,</line> <line>my <span class="context">name</line> <line>is farhad </line> <line><span class="word">and</span> i'm having</span></line> <line>trouble with xslt</line> with problems of overlapping, but now it's not a problem (i think i know how manage it). How can i search a word and its context? Thank you very much.

  • Back again to use Rails 2.3.5 from Rails 3

    - by dreame4
    Hi, Recently, I had seen information about Rails 3.0 beta and I had wanted to trial it. So I used gem update and installed this version. But now, I need to go back to Rails 2.3.5. How could I do it? I was thinking about this two solutions: Uninstalling Rails 3. I read that somebody removed Rails 3 by using gem uninstall but he came across some problems then. Did anyone try to remove it in this way? Using different versions Rails at the same time. Is it possible at all? It will resolve all my problems but I could find nothing about this issue in google. Hope somebody could help me :) Greetings, dreame4

  • Unique ways to use the Null Coalescing operator

    - by Atomiton
    I know the standard way of using the Null coalescing operator in C# is to set default values. string nobody = null; string somebody = "Bob Saget"; string anybody = ""; anybody = nobody ?? "Mr. T"; // returns Mr. T anybody = somebody ?? "Mr. T"; // returns "Bob Saget" But what else can ?? be used for? It doesn't seem as useful as the ternary operator, apart from being more concise and easier to read than: nobody = null; anybody = nobody == null ? "Bob Saget" : nobody; // returns Bob Saget So given that fewer even know about null coalescing operator... Have you used ?? for something else? Is ?? necessary, or should you just use the ternary operator (that most are familiar with)

  • Traditional loop versus Action delegate in C#

    - by emddudley
    After learning about the Action delegate in C# I've been looking for ways I can best use it in my code. I came up with this pattern: Action<string> DoSomething = (lSomething) => { // Do something }; DoSomething("somebody"); DoSomething("someone"); DoSomething("somewhere"); If I were to have used a traditional loop, it would look something like this: List<string> lSomeList = new List<string>(); lSomeList.Add("somebody"); lSomeList.Add("someone"); lSomeList.Add("somewhere"); foreach (string lSomething in lSomeList) { // Do something } Are there any appreciable differences between the two? To me they look equally easy to understand and maintain, but are there some other criteria I might use to distinguish when one might be preferred over the other?

  • Routing to a Terminal Services Cluster

    - by Dave
    I am trying to connect to a Load Balanced Windows 2008 R2 cluster using Remote Desktop Services. I have no trouble connecting to the the Servers' IP addresses (.253.16 and .253.17) or the Cluster address (.253.20) from inside the subnet (.253). The trouble is when I try to connect from the other subnet(.251). I can remote to the other non-clustered servers (.253.12 and .253.15) inside the .253 subnet from the .251 without an issue. I receive a ping reply from the cluster and other servers when I am on the .251 subnet. But when I try to connect via remote desktop it times out but only to any of the IPs on the cluster (.20,.17,.16). My ASA 5510 handling the routing reports message in the log: Deny TCP (no connection) from 192.168.251.2/4283 to 192.168.253.16/3389 flag FIN PSH ACK Here is a picture if it helps http://dl.dropbox.com/u/4217864/terminal%20server.jpg Thanks for any help

  • Safari Extension - How to respond to Settings changes?

    - by Martin Marlow
    Hi, I'm currently working on an Extension for Safari 5 and I want to run a listener function whenever Settings changes are made. Apple provides an example for that, but it doesn't work for me. I currently have this listener function in my global html file: function numberChanged() { if(event.key == "number") alert("Number has changed!"); } safari.self.addEventListener("change", numberChanged, false); I hope somebody can help me. Does somebody know what I'm doing wrong?

  • Configuration manager for PHP

    - by Jack
    I am working on code re-factoring of configuration file loading part in PHP. Earlier I was using multiple 'ini' files but now I plan to go for single XML file which will be containing all configuration details of the project. Problem is, if somebody wants configuration file in ini or DB or anything else and not the default one (in this case XML), my code should handle that part. If somebody wants to go for other configuration option like ini, he will have to create ini file similar to my XML configuration file and my configuration manager should take care everything like parsing, storing in cache. For that I need a mechanism lets say proper interface for my configuration data where the underlying data store can be anything( XML, DB, ini etc) also I don't want it to be dependent on these underlying store and anytime in future this should be extensible to other file formats.

  • AMD Phenom II X4 965 crossfire motherboard

    - by Nick
    I am trying to build a cheap mining rig. I wanted to use the AMD Phenom II X4 965 (HDZ965FBGMBOX) processor as it got very good reviews and benchmarks, and is inexpensive. However, I am having trouble finding motherboards with crossfire support for 2 GPUs. AMD's website only lists five compatible motherboards, of which only one has crossfire support. Worse, it is expensive and seems to be obsolete and no longer available. I have trouble believing that there are only five compatible motherboards for that CPU. Are there any low-end motherboards that are both compatible with the AMD Phenom II X4 965 and have CrossFire support? (Is there a way to find this sort of information, like a central site that lists motherboards and their technical specifications?)

  • Compiling Assembly Manually [migrated]

    - by John Smith
    I am having trouble with translating a specific line in assembly to machine code for the Nios II. I have successfully compiled these lines: START_TIMER = 0xF68C r0 = 0x0 r8 = 0x8 label = 50000 addi r8, r8, %lo(label) - 01000 01000 1100001101010000 000100 subi r8, r8, 1 - 01000 01000 1111111111111111 000100 bne r8, r0, START_TIMER - 01000 00000 1111011010001100 011110 The line in question that I have trouble with is this one: orhi r8, r0, %hiadj(label) As explained in the handbook linked above, "%lo" means "Extract bits [15..0] of immed32" and "%hiadj" means "Extract bits [31..16] and adds bit 15 of immed32". However, 50000 in binary is 1100001101010000, and is therefore a 16 bit number. As far as I can see, it doesn't contain any bits between 16 and 31. I tried with 0000000000000001, but it's incorrect. What am I doing wrong?

  • In Haskell, how can you sort a list of infinite lists of strings?

    - by HaskellNoob
    So basically, if I have a (finite or infinite) list of (finite or infinite) lists of strings, is it possible to sort the list by length first and then by lexicographic order, excluding duplicates? A sample input/output would be: Input: [["a", "b",...], ["a", "aa", "aaa"], ["b", "bb", "bbb",...], ...] Output: ["a", "b", "aa", "bb", "aaa", "bbb", ...] I know that the input list is not a valid haskell expression but suppose that there is an input like that. I tried using merge algorithm but it tends to hang on the inputs that I give it. Can somebody explain and show a decent sorting function that can do this? If there isn't any function like that, can you explain why? In case somebody didn't understand what I meant by the sorting order, I meant that shortest length strings are sorted first AND if one or more strings are of same length then they are sorted using < operator. Thanks!

I get this error when I run the troubleshooting option. I met two more people in the same hotel with win XP laptop and they too dont have any problem. I have gone to possibly all the forums and website but I haven't been able to fix this error :(. I have done all the basic troubleshooting but I have no luck yet. Pls help.
