  • Excel vba: error hiding calculated field in Pivot table

    - by Patrick Honorez
    I have written several Subs to show/hide fields in a PivotTable. Now I am trying to do the same with a calculated field, but I get an error when hiding it. I took my code from the recorder and the recorder's code also halts on the last line. I googled the error message, without serious result. Sub PrRemove() 'remove PR Dim pt As PivotTable Set pt = ActiveSheet.PivotTables("MyPivot") pt.PivotFields("MyField").Orientation = xlHidden '<- here is the error End Sub The same code works fine if MyField is a normal field (not a calculated one). I am using Excel 2007 with SP2. Any clue ?

  • MooTools Event Delegation using HTML5 data attributes.

    - by Anurag
    Is it possible to have event delegation using the HTML5 data attributes in MooTools? The HTML structure I have is: ?<div id="parent"> <div>not selectable</div> <div data-selectable="true">selectable</div> <div>not selectable either.</div> <div data-selectable="true">also selectable</div> </div>???????????????????????????????????????????????????????????????????????? And I want to setup <div id="parent"> to listen to all clicks only on child elements that have the data-selected attribute. Please let me know if I'm doing something wrong: The events are being setup as: $("parent").addEvent("click:relay([data-selectable])", function(event, el) { alert(this.get('text')); }); but the click callback is fired on clicking all div's, not just the ones with a data-selectable attribute defined. You can see this example on http://jsfiddle.net/NUGD4/ A workaround is to adding this as a CSS class, which works with delegation but I would prefer to be able to use data-attributes as it's used throughout the application.

  • Error in simple Java application

    - by mrblah
    Just playing around with java trying to learn it etc. Here is my code so far, using HtmlUnit. package hsspider; import com.gargoylesoftware.htmlunit.WebClient; /** * @author */ public class Main { /** * @param args the command line arguments */ public static void main(String[] args) { System.out.println("starting "); Spider spider = new Spider(); spider.Test(); } } package hsspider; import com.gargoylesoftware.htmlunit.WebClient; import com.gargoylesoftware.htmlunit.html.HtmlPage; /** * @author */ public class Spider { public void Test() throws Exception { final WebClient webClient = new WebClient(); final HtmlPage page = webClient.getPage("http://www.google.com"); System.out.println(page.getTitleText()); } } I am using Netbeans. I can't seem to figure out what the problem is, why doesn't it compile? The error: C:\Users\mrblah\.netbeans\6.8\var\cache\executor-snippets\run.xml:45: Cancelled by user. BUILD FAILED (total time: 0 seconds) The row in the xml is: <translate-classpath classpath="${classpath}" targetProperty="classpath-translated" />

  • Is there a dojo enhanced grid example with context menu

    - by user102023
    I am looking for an example of a dojo enhanced grid that contains a context menu on either a cell or row menu where the cell or row data is accessed. I have managed to create an enhanced grid with a row context menu. I can create a function that captures the event of clicking on the row menu item. However, I am not sure how to access the row data in the context of the menu item handler. I have not seen any example in the tests of the nightly build. Is there an example of this available online?

  • T4 Toolbox - mixing class feature and statement blocks

    - by Mauricio Scheffer
    I'm a T4 newbie trying to use T4 Toolbox to generate F# code based on this answer, but it seems that class feature blocks can't be mixed with statement blocks. Here's my code: <#@ template language="C#" hostspecific="True" debug="True" #> <#@ output extension="txt" #> <#@ include file="T4Toolbox.tt" #> <# FSharpTemplate template = new FSharpTemplate(); template.Output.Project = @"..\Library1\Library1.fsproj"; template.Output.File = "Module2.fs"; template.Render(); #> <#+ class FSharpTemplate: Template { public override string TransformText() { #> module Module2 <# for (int i = 0; i < 10; i++) { #> <#= i #> <# } #> <#+ return this.GenerationEnvironment.ToString(); } } #> And I get this error: A Statement cannot appear after the first class feature in the template. Only boilerplate, expressions and other class features are allowed after the first class feature block. So... how can I rewrite the template to achieve this?

  • returning aligned memory with new?

    - by Steve
    I currently allocate my memory for arrays using the MS specific mm_malloc. I align the memory, as I'm doing some heavy duty math and the vectorization takes advantage of the alignment. I was wondering if anyone knows how to overload the new operator to do the same thing, as I feel dirty malloc'ing everywhere (and would eventually like to also compile on Linux)? Thanks for any help

  • Pipe data from InputStream to OutputStream in Java

    - by Wangnick
    Dear all, I'd like to send a file contained in a ZIP archive unzipped to an external program for further decoding and to read the result back into Java. ZipInputStream zis = new ZipInputStream(new FileInputStream(ZIPPATH)); Process decoder = new ProcessBuilder(DECODER).start(); ??? BufferedReader br = new BufferedReader(new InputStreamReader( decoder.getInputStream(),"us-ascii")); for (String line = br.readLine(); line!=null; line = br.readLine()) { ... } What do I need to put into ??? to pipe the zis content to the decoder.getOutputStream()? I guess a dedicated thread is needed, as the decoder process might block when its output is not consumed.

  • NHibernate and MySql Keywords

    - by jalchr
    Why Nibernate HQL can not handle the following query: from Deal D where (D.ApprovalDate + INTERVAL 1 Year) < current_timestamp() < (D.RenewalDate + INTERVAL -1 Year) knowing that INTERVAL and YEAR are keywords in MySQL, so this is kind of mixing Sql within Hql (unless Hql can handle date functions like so and I don't know) . The dialect is MySQLDialect Its perfectly valid to execute this query SELECT '2005-01-01' + INTERVAL 1 Year;

  • How do I use postfix aliases in cyrus?

    - by Nick
    I have a cyrus mailbox called user/nrahl. If I use the 'mail' command, from the server itself, and type: mail nrahl to send a message, the message magically shows up in my Thunderbird IMAP inbox. But I need to get message from a POP3 account into Cyrus for delivery, and the messages comming in are addressed to "[email protected]". I have fetchmail setup and running, and it's downloading messages from the POP3 account, and passing them into Postfix. Postfix (now that I've got aliases set up in /etc/alias) is accepting the message, and passing it to the Cyrus socket. But here's the problem: Cyrus is rejecting the message with a 550 - mailbox unknown error. The actual message in /var/log/mail.log is: Apr 17 16:56:57 IMAP cyrus/lmtpunix[5640]: verify_user(user.fetchmail) failed: Mailbox does not exist Apr 17 16:56:57 IMAP postfix/lmtp[5561]: CFFD61556BD: to=, relay=localhost[/var/run/cyrus/socket/lmtp], delay=0.08, delays=0.07/0/0/0.01, dsn=5.1.1, status=bounced (host localhost[/var/run/cyrus/socket/lmtp] said: 550-Mailbox unknown. Either there is no mailbox associated with this 550-name or you do not have authorization to see it. 550 5.1.1 User unknown (in reply to RCPT TO command)) It looks like it's trying to forward all of nrahl's mail to postfix@localhost, instead of nrahl@localhost, and I don't know why. I need it to forward mail addressed to [email protected] into Cyrus's "nrahl" mailbox.

  • How do I delete a route in OS X 10.5

    - by authormichael-olsen-craig
    I somehow configured my Mac to route all requests for a particular IP Name (sample.com) to the loopback address (127.0.0.1). Now I'm trying to remove this, but can't determine where to do it. There is no entry for it under /etc/hosts. The routing table shows that it is mapping the IP Name to the IP address of the Mac. Routing table output below: Internet: Destination Gateway Flags Refs Use Netif Expire default 192.168.2.1 UGSc 4 1 en0 127 sample.com UCS 0 0 lo0 sample.com sample.com UH 1 7093 lo0 169.254 link#4 UCS 0 0 en0 192.168.2 link#4 UCS 6 0 en0 192.168.2.1 0:11:22:22:3f:fa UHLW 20 55565 en0 1070 192.168.2.15 tsema.org UHS 0 9 lo0 192.168.2.255 link#4 UHLWb 4 84777 en0 Any help would be greatly appreciated!

  • Cheap desktop computer in 19" rack-mountable form-factor?

    - by Alex Basson
    I'm a high school teacher at a small private school. As of this year, we have SMARTBoards in every classroom (though I've had one in the class I share for two years now). The classrooms themselves don't have computers in them, so we teachers bring our laptops to class and connect them to the boards. This has several disadvantages: This takes a few minutes while we wait for the board to boot up and then orient the board to our individual laptop -- we have to do this every time b/c different teachers have different laptops requiring different orientations. This isn't ideal because when you only have 43 minutes per class period, waiting five minutes just to get started is a real waste. Carrying your laptop to class doesn't sound so bad until you consider that we're also carrying textbooks and piles of student papers, and we're carrying it all through crowded high school hallways. More than one laptop has fallen THUNK to the floor, with dire consequences. We feel we could eliminate the need to use our laptops with the SMARTBoards if we had a dedicated computer in each classroom hooked up to the board at all times. Each board set-up is connected to a podium with a standard 19" rack in it, currently housing a power supply and DVD player. There're plenty of rack spaces available. So I'm thinking: maybe we could get some inexpensive computers in a 19" rack-mountable form factor, install them in the podiums, and connect them to the boards on a permanent basis. Any suggestions?

  • 2.5" SSD in a 3.5" desktop drive bay normal?

    - by Cory Petosky
    I'm a little out of touch with modern desktop builds, but I recently built a new machine anyway. I want to pick up a SSD for my I/O intensive apps (EverQuest 2 and Flash CS4 mostly), but I'm having trouble finding any in the 3.5" form factor. Is this expected, or do I fail at product search? And, if it is expected, do 2.5" SSDs come with an adapter to fit them in my desktop machine, or will I need to purchase one separately? And, finally, if I do need to purchase an adapter, are they pretty standard or are some better than others. General advice is most welcomed, though specific product recommendations in addition would be helpful!

  • Adding a method to a function object at runtime

    - by Carson Myers
    I read a question earlier asking if there was a times method in Python, that would allow a function to be called n times in a row. Everyone suggested for _ in range(n): foo() but I wanted to try and code a different solution using a function decorator. Here's what I have: def times(self, n, *args, **kwargs): for _ in range(n): self.__call__(*args, **kwargs) import new def repeatable(func): func.times = new.instancemethod(times, func, func.__class__) @repeatable def threeArgs(one, two, three): print one, two, three threeArgs.times(7, "one", two="rawr", three="foo") When I run the program, I get the following exception: Traceback (most recent call last): File "", line 244, in run_nodebug File "C:\py\repeatable.py", line 24, in threeArgs.times(7, "one", two="rawr", three="foo") AttributeError: 'NoneType' object has no attribute 'times' So I suppose the decorator didn't work? How can I fix this?

  • Could the cause of recent Toyota computing problems be an interface mismatch ?

    - by Spux
    Any ideas if the recent Toyota computing errors had something to do with the fact they where using an object orintated approach then took a data orientated approach thus causing user interface errors ? Studying programming languages with in interface robotic design and wondered if the car computing glitch Toyota has been having could have something to do with using a different programming approach with out reprogramming the whole system from scratch.

  • Can I create a UITableViewController that inherits from a custom subclass of UIViewController?

    - by prendio2
    I have common functionality that I need to access from all screens of my app: a right bar button item and associated action. So as not to repeat the code I would like to set this up in a custom UIViewController and have all my view controllers inherit from it. - (void)viewDidLoad { UIBarButtonItem *rightBarButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemPlay target:self action:@selector(lightsCamera)]; self.navigationItem.rightBarButtonItem = rightBarButton; } - (void)lightsCamera { … } However, I have a number of UITableViewControllers however and I would like to know if it is possible for them to inherit the functionality too?

  • Curious: Could LLVM be used for Infocom z-machine code, and if so how? (in general)

    - by jonhendry2
    Forgive me if this is a silly question, but I'm wondering if/how LLVM could be used to obtain a higher performance Z-Machine VM for interactive fiction. (If it could be used, I'm just looking for some high-level ideas or suggestions, not a detailed solution.) It might seem odd to desire higher performance for a circa-1978 technology, but apparently Z-Machine games produced by the modern Inform 7 IDE can have performance issues due to the huge number of rules that need to be evaluated with each turn. Thanks! FYI: The Z-machine architecture was reverse-engineered by Graham Nelson and is documented at http://www.inform-fiction.org/zmachine/standards/z1point0/overview.html

  • Useful Vim features

    - by Craig H
    Vim is my editor of choice, and I feel I am above average in my use of it. I do recognize, though, that the feature list of vim is huge. With this in mind, I was wondering what features you vim users out there use on a regular basis.
