  • Execute an autocommand only once

    - by Andrej M.
    I have an issue with using GVim on Windows. I have set up the following in my .vimrc: if has("gui_running") autocmd VIMEnter * :source C:/session.vim endif Unfortunately this creates a problem. If I'm a the top of the file and try to move up a line (k), the screen flashes. If I hold the key for just a second it will flash a few dozen times, it is really nasty too look at. I've tried using GUIEnter instead but I got the same results. The docs mention that I can fire an autocommand only once, but I couldn't figure out the exact syntax. Care to help?

  • Dynamic typed language example using ANTLR

    - by wvd
    Hey all, I'm looking for some ANTLR examples, I tried googling a bit but I found certain things which didn't fit my requirments. I found the Mantra project, but it's statically typed and is 'too' big for me at this moment, then I found 'pie' as interpreter, which is dynamically typed, which what I want, but it uses a syntax-directed interpreter. I'm looking for a pretty small language which is dynamically typed and uses AST's if possible. It doesn't need to be advanced, if it would have classes I would already be very happy. Thanks, William van Doorn

  • How can I store data in a table as a trie? (SQL Server)

    - by Matt
    Hi, To make things easier, the table contains all the words in the English dictionary. What I would like to do is be able to store the data as a trie. This way I can traverse the different branches of the trie and return the most relevant result. First, how do I store the data in the table as a trie? Second, how do I traverse the tree? If it helps at all, the suggestion in this previous question is where this question was sparked from. Please make sure it's SQL we're talking about. I understood the Mike Dunlavey's C implementation because of pointers but can't see how this part (The trie itself) works in SQL. Thanks, Matt

  • resolving localhost in php so can be views outside VM

    - by DA
    I'm running Windows 7. Within, I'm running Virtualbox and Ubuntu. Within Ubuntu, I'm running Apache and using PHP codeigniter. To reference our CSS and JS files, we use this syntax: <?php echo site_url('css/styles.css'); ?> When viewing the site locally (within Ubuntu VM) that resolves to: http://localhost/styles.css So works fine. The catch is when I access that site from within Windows 7 (for IE testing). To access the site in Windows 7, I refer to the IP address of the VM: http://xx.x.x.x/ That loads the site but, alas, all the site_url variables are still being rewritten as 'localhost'. Said files obviously don't exist on the localhost of my windows 7. Is there a way around this short of just hard-coding relative links in my PHP file?

  • What are possible reasons for java.io.IOException: "The filename, directory name, or volume label sy

    - by Turismo
    I am trying to copy a file using the following code: File targetFile = new File(targetPath + File.separator + filename); ... targetFile.createNewFile(); fileInputStream = new FileInputStream(fileToCopy); fileOutputStream = new FileOutputStream(targetFile); byte[] buffer = new byte[64*1024]; int i = 0; while((i = fileInputStream.read(buffer)) != -1) { fileOutputStream.write(buffer, 0, i); } For some users the targetFile.createNewFile results in this exception: java.io.IOException: The filename, directory name, or volume label syntax is incorrect at java.io.WinNTFileSystem.createFileExclusively(Native Method) at java.io.File.createNewFile(File.java:850) Filename and directory name seem to be correct. The directory targetPath is even checked for existence before the copy code is executed and the filename looks like this: AB_timestamp.xml The user has write permissions to the targetPath and can copy the file without problems using the OS. As I don't have access to a machine this happens on yet and can't reproduce the problem on my own machine I turn to you for hints on the reason for this exception.

  • jQuery Delay Question

    - by Fuego DeBassi
    <script type="text/javascript"> $(document).ready(function() { $(".module .caption").hide(); $(".module").hover(function() { $(this).find(".caption").slideDown().end().siblings('.module').addClass('under'); },function() { $(this).find(".caption").slideUp().end().siblings('.module').removeClass('under').delay(10000); }); }); </script> This works great, except the .delay doesn't work, is my syntax wrong? I'm just trying to accomplish haveing the .removeClass("under") delayed by a second or two when the mouse un-hovers. I don't want to delay the slideUp. Any ideas?

  • Custom Validation on jquery validate plugin, need to count element in a multiple select

    - by 0plus1
    I have a multiple select, and I need to force the user to choose maximum two options, nothing more. I'm trying this: jQuery.validator.addMethod("morethantwo", function(value, element) { var foo = []; $(element+' :selected').each(function(i, selected){ foo[i] = $(selected).text(); alert(foo[i]); }); return true; },"Max two options." ); The problem is that I get a: uncaught exception: Syntax error, unrecognized expression: [object HTMLSelectElement] error. While if I do this: $(element).each(function(i, selected){ foo[i] = $(selected).text(); alert(foo[i]); }); It works but I get all the options in the select. Why is that? Is this the correct road to walk? Are there better ways to do this kind of check? Thank you very much!

  • Displaying UserControls based on the type a TreeView selection is bound to

    - by Ray Wenderlich
    I am making an app in WPF in a style similar to Windows Explorer, with a TreeView on the left and a pane on the right. I want the contents of the right pane to change depending on the type of the selected element in the TreeView. For example, say the top level in the Tree View contains objects of class "A", and if you expand the "A" object you'll see a list of "B" objects as children of the "A" object. If the "A" object is selected, I want the right pane to show a user control for "A", and if "B" is selected I want the right pane to show a user control for "B". I've currently got this working by: setting up the TreeView with one HierarchialDataTemplate per type adding all the UserControls to the right pane, but collapsed implementing SelectedItemChanged on the TreeView, and setting the appropriate usercontrol to visible and the others to collapsed. However, I'm sure there's a better/more elegant way to switch out the views based on the type the selection is bound to, perhaps by making more use of data binding... any ideas?

  • How can I edit a css rule in jQuery?

    - by chacham15
    The purpose is that rows are dynamically added to a table and it is not as nice (and slower) to apply the rule manually later. The specific example is that I am creating a tree table to represent a folder directory. Each folder is a div. In each div, there is a ul with an li for each columns' information. These li have a class name equivalent to the column name. This provides column width. I want to make the columns resizable however. I could do $('.className').css('width', newWidth) but then this wont apply to newly inserted items. Therefore, I want to modify the css rule. How do I do this?

  • updating all other records

    - by Andrew Welch
    Hi, I've got a query below. I want to add a condition that if the parameter of @IsPrestigeFeatured = 0 then update all of the other rows < PropertyId in the IsprestigeFeatured column to 0 and if @IsPrestigeFeatured = 1 then IsprestigeFeatured = 1 where propertyId = PropertyId.

  • Author in wiki, generate PDF documents, CHM files or embedded help

    - by Dilum Ranatunga
    Anyone know of a wiki or wiki plugin that generates a PDF file or CHM file that spans the entire wiki? I would like to have control of the table of contents. I would like the internal and external links to work. Ideally allow for tweaking the output template, but that is not a deal-breaker. I want to generate content using WIKI syntax and mindset (lots of cross-links etc), but ship the content in PDF, CHM or an embedded application form. Something friendlier than installing the wiki software on the enduser machine...

  • Is there a way to disable calls to Runtime.checkRestricted on the GAE Java development server under Eclipse?

    - by Thomas Becker
    I'm one of those guys who step through their code a lot during development. Beginning with version 1.6.4 of the GAE Java development server, the server has been instrumented with calls to a function named Runtime.checkRestricted. This causes two inconveniences when I step through my code: 1) Whenever I step into a function, the debugger goes into the function Runtime.checkRestricted (for which there is no source code) at least once, often multiple times. 2) Whenever I step over a function call which has a large call tree underneath it, then it takes a very long time for the debugger to come back. (That's always a problem in the Eclipse Java debugger, but now it's really bad.) For me, all this causes a serious drain on productivity. Is there any way to disable this instrumentation, or to prevent the debugger from stepping into it? I am using Eclipse with the GAE plugin.

  • Java == operator. "Invalid assignment operator"

    - by Tom
    Hi, I was trying to write a simple method boolean validate(MyObject o) { return o.getPropertyA() == null && o.getPropertyB()==null; } And got a strange error on the == null part. Maybe my Java is rusty after a season in PLSQL. Consider this: Integer i = 4; i ==null; //compile error: Syntax error on token ==. Invalid assignment operator. Integer i2 = 4; if (i==null); //No problem How can this be ? Any explanation ? Im using jdk160_05.

  • SQL Having Clause

    - by Wally
    I'm trying to get a stored procedure to work using the following syntax: select count(sl.Item_Number) as NumOccurrences from spv3SalesDocument as sd left outer join spv3saleslineitem as sl on sd.Sales_Doc_Type = sl.Sales_Doc_Type and sd.Sales_Doc_Num = sl.Sales_Doc_Num where sd.Sales_Doc_Type='ORDER' and sd.Sales_Doc_Num='OREQP0000170' and sl.Item_Number = 'MCN-USF' group by sl.Item_Number having count (distinct sl.Item_Number) = 0 In this particular case when the criteria is not met the query returns no records and the 'count' is just blank. I need a 0 returned so that I can apply a condition instead of just nothing. I'm guessing it is a fairly simple fix but beyond my simple brain capacity. Any help is greatly appreciated. Wally

  • Is there a config option in PHP to prevent undefined constants from being interpreted as strings?

    - by mrbinky3000
    This is from the php manual: http://us.php.net/manual/en/language.constants.syntax.php If you use an undefined constant, PHP assumes that you mean the name of the constant itself, just as if you called it as a string (CONSTANT vs "CONSTANT"). An error of level E_NOTICE will be issued when this happens. I really don't like this behavior. If I have failed to define a required constant, I would rather the script fail so that I am forced define it. Is there any way to force PHP to crash the script if it tries to use an undefined constant? For example. Both of these scripts do the same thing. <?php define('DEBUG',1); if (DEBUG) echo('Yo!'); ?> and <?php if(DEBUG) echo('Yo!'); ?> I would rather the second script DIE and declare that it tried to use an undefined constant DEBUG.

  • c# Attribute Question

    - by Petoj
    Well i need some help here i don't know how to solve this problem. the function of the attribute is to determine if the function can be run... So what i need is the following: The consumer of the attribute should be able to determine if it can be executed. The owner of the attribute should be able to tell the consumer that now it can/can't be executed (like a event). It must have a simple syntax. This is what i have so far but it only implements point 1, 3. [AttributeUsage(AttributeTargets.Method, AllowMultiple = false)] public class ExecuteMethodAttribute : Attribute { private Func<object, bool> canExecute; public Func<object, bool> CanExecute { get { return canExecute; } } public ExecuteMethodAttribute() { } public ExecuteMethodAttribute(Func<object, bool> canExecute) { this.canExecute = canExecute; } }

  • In OpenRasta, how do I configure a URI where I get "the remainder of the path" as a single string?

    - by Daniel Earwicker
    Normally in OpenRasta there is some configuration like this: ResourceSpace.Has.ResourcesOfType<Customers>() .AtUri("/customers/region/{region}") ... // and so on ... where the {region} part of the path is automatically mapped to a string parameter in the handling method. So if the user hits: http://server/customers/region/emea Then the handler method is passed the string "emea". As well as doing this, I'd like to register a handler with something like this: ResourceSpace.Has.ResourcesOfType<Customers>() .AtUri("/someotherthing/*") ... // and so on In this imaginary syntax, the asterisk would mean "take the rest of the path, including slashes, to be a single string parameter to pass to the handling method". And so if the user hits: http://server/someotherthing/how/about/this?that=other Then my handler method receives a string parameter: how/about/this?that=other Is such a thing possible in OpenRasta? In Sinatra (Ruby) I'd use a regular expression to do exactly this.

  • PHP - Cannot use Heredoc within a class method?

    - by Dan
    I'm writing the code for a controller method and I need to use it to send an email. I'm trying to use heredoc syntax to fill in the email body, however, the closing tag doesn't seem to be recognized. $this->email = new Email(); $this->email->from = 'Automated Email'; $this->email->to = '[email protected]'; $this->email->subject = 'A new user has registered'; $this->email->body = <<<EOF Hello, a new user has registered. EOF; $this->email->send(); Everything from the opening <<< EOF down (till the end of the file) is displayed as if it was in quotes. Can anyone see why this is not working? Any advice appreciated. Thanks.

  • Expected ')' before '*' token

    - by Danni
    So this is more of a syntax problem. I keep getting the error "Expected ')' before '*' token" on the line: #include "CDocumentObserver.h" #include "CViewPlayerDlg.h" /* * Class: CViewPlayer * */ class CViewPlayer : public wxWindow, public CDocumentObserver { public: CViewPlayer(CViewPlayerDlg *dlg); //here in CViewPLayer.h.

  • CREATE mysql database with default InnoDB tables?

    - by memilanuk
    Hello, I've been working on writing a SQL statement to create a MySQL database with several default options, including default character set and default collate. Is it possible to add syntax to make the default engine type for tables in this database to be innodb? I've been looking through the MySQL manual for v.5.1 and I've found the statement 'ENGINE=innodb' which would be appended to a CREATE TABLE statement... but I haven't found anything related to a CREATE DATABASE statement. Is there a normal way to do this as part of the database creation, or does it need to be specified on a table-by-table basis? Thanks, Monte

  • Can't access dojo object property using string variable

    - by Kareem
    I am retrieving a json associative array using a dojo xhrGet request. The data comes back just fine, however I need the app to be able to display the keys and their properties (or values) without knowing the keys beforehand. So, I do the following: function getData() { dojo.xhrGet( { url: "ytd_process.php", handleAs: "json", load: function(response) { for (var key in response) { dojo.byId("boxes").innerHTML+="<div id=\"box\">"+key+":"+response.key+"</div>"; } console.dir(response); // Dump it to the console } }); }; The keys are retrieved and displayed on the page, but the response.key returns undefined. I know the syntax is correct because if I replace .key with an actual key value it will display correctly. It appears it doesn't like a string as the key. Any help or advice would be greatly appreciated. Thank you.

  • How to maintain tabs when pasting in Vim

    I use the tab key to indent my python code in Vim, but whenever I copy and paste a block Vim replaces every tab with 4 spaces, which raises an IndentationError I tried setting :set paste as suggested in related questions but it makes no difference Other sites suggest pasting 'tabless' code and using the visual editor to re-indent, but this is asking for trouble when it comes to large blocks Are there any settings I can apply to vim to maintain tabs on copy/paste? Thanks for any help with this :) edit: I am copying and pasting within vim using the standard gnome-terminal techniques (ctrl+shift+c / mouse etc.) my .vimrc is: syntax on set ts=4 if has("terminfo") let &t_Co=8 let &t_Sf="\e[3%p1%dm" let &t_Sb="\e[4%p1%dm" else let &t_Co=8 let &t_Sf="\e[3%dm" let &t_Sb="\e[4%dm" endif I looked up that ts - Sets tab stops to n for text input, but don't know what value would maintain a tab character
