  • Cannot find CFML template for custom tag

    - by jerrygarciuh
    Hi folks, I am not a ColdFusion coder. Doing a favor for a friend who ported his CF site from a Windows server to Unix on GoDaddy. Site is displaying error: Cannot find CFML template for custom tag jstk. ColdFusion attempted looking in the tree of installed custom tags but did not find a custom tag with this name. The site as I found it has at document root /CustomTags with the jstk.cfm file and a set of files in cf_jstk My Googling located this You must store custom tag pages in any one of the following: The same directory as the calling page; The cfusion\CustomTags directory; A subdirectory of the cfusion\CustomTags directory; A directory that you specify in the ColdFusion Administrator So I have Tried creating placing /CustomTags in /cfusion/CustomTags Tried copying /cfusion/CustomTags to above document root Tried copying jstk.cfm and subfolders into same directory as calling file(index.cfm). Update: Per GoDaddy support I have also tried adding the following to no effect: Can any one give me some tips on this or should I just tell my guy to look for a CF coder? Thanks! JG

  • How do I create a hybrid two column lay out like php.net?

    - by Koning WWWWWWWWWWWWWWWWWWWWWWW
    I want to create a layout like this: | | | | | | | | | | | | | | | | -FIXED-|--------FLUID---------| | | | | | | | | | | | | | | Just like http://www.php.net/ I have this: div#sidebar { float: left; width: 200px; padding: 4px; background-color: #EEEEEE; border-right: dashed 1px #AAAAAA; } div#content { padding: 4px; margin-left: 208px; } But the problem is that the sidebar isn't at least the height of the content block (which it should be). Can anyone help me? Thanks Oh, one more thing: I will never, ever use a table for this!

  • Is there an algorithm for finding an item that matches certain properties, like a 20 questions game?

    - by lala
    A question about 20 questions games was asked here: However, if I'm understanding it correctly, the answers seem to assume that each question will go down a hierarchal branching tree. A binary tree should work if the game went like this: Is it an animal? Yes. Is it a mammal? Yes. Is it a feline? Yes. Because feline is an example of a mammal and mammal is an example of an animal. But what if the questions go like this? Is it a mammal? Yes. Is it a predator? Yes. Does it have a long nose? No. You can't branch down a tree with those kinds of questions, because there are plenty of predators that aren't mammals. So you can't have your program just narrow it down to mammal and have predators be a subset of mammals. So is there a way to use a binary search tree that I'm not understanding or is there a different algorithm for this problem?

  • How do you specify a 64 bit unsigned int const 0x8000000000000000 in VS2008?

    - by Mark Franjione
    I read about the Microsoft specific suffix "i64" for integer constants. I want to do an UNsigned shift to a ULONGLONG. ULONGLONG bigNum64 = 0x800000000000000i64 >> myval; In normal C, I would use the suffix "U", e.g. the similar 32 bit operation would be ULONG bigNum32 = 0x80000000U >> myval; I do NOT want the 2's complement sign extension to propogate through the high bits. I want an UNSIGNED shift on a 64 bit const number. I think my first statement is going to do a SIGNED shift right. I tried 0x800000000000000i64U and 0x800000000000000u64 but got compiler errors.

  • cmake add_library at a custom location

    - by celil
    I need to build a library that is to be placed at a custom location stored in the variable CUSTOM_OUTDIR. Currently, I am using the following code to make sure that the library is copied to its proper location. ADD_LIBRARY(example MODULE example.c) GET_TARGET_PROPERTY(FILEPATH example LOCATION) ADD_CUSTOM_COMMAND( TARGET example POST_BUILD COMMAND ${CMAKE_COMMAND} ARGS -E copy ${FILEPATH} ${CUSTOM_OUTDIR} ) However, this is not a good solution as the copying is done post_build, and I end up with two copies of the library. Is there a way to setup CMAKE_BINARY_DIR just for the example library so that only one copy of it is kept in the proper location?

  • AvalonDock + UserControl + DataGrid + ContextMenu command routing issue

    - by repka
    I have this kind of layout: <Window x:Class="DockAndMenuTest.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:ad="clr-namespace:AvalonDock;assembly=AvalonDock" Title="MainWindow" Height="350" Width="525"> <ad:DockingManager> <ad:DocumentPane> <ad:DockableContent Title="Doh!"> <UserControl> <UserControl.CommandBindings> <CommandBinding Command="Zoom" Executed="ExecuteZoom" CanExecute="CanZoom"/> </UserControl.CommandBindings> <DataGrid Name="_evilGrid"> <DataGrid.Resources> <Style TargetType="DataGridRow"> <Setter Property="ContextMenu"> <Setter.Value> <ContextMenu> <MenuItem Command="Zoom"/> </ContextMenu> </Setter.Value> </Setter> </Style> </DataGrid.Resources> </DataGrid> </UserControl> </ad:DockableContent> </ad:DocumentPane> </ad:DockingManager> </Window> Briefly: ContextMenu is set for each DataGridRow of DataGrid inside UserControl, which in its turn is inside DockableContent of AvalonDock. Code-behind is trivial as well: public partial class MainWindow { public MainWindow() { InitializeComponent(); _evilGrid.ItemsSource = new[] { Tuple.Create(1, 2, 3), Tuple.Create(4, 4, 3), Tuple.Create(6, 7, 1), }; } private void ExecuteZoom(object sender, ExecutedRoutedEventArgs e) { MessageBox.Show("zoom !"); } private void CanZoom(object sender, CanExecuteRoutedEventArgs e) { e.CanExecute = true; } } So here's the problem: right-clicking on the selected row (if it it was selected before the right click) my command comes out disabled. The command is "Zoom" in this case, but can be any other, including a custom one. If I get rid of either docking or UserControl around my grid there are no problems. ListBox doesn't have this issue either. So I don't know what's at fault here. SNOOP shows that in cases when this propagation fails, instead of UserControl, CanExecute is handled by PART_ShowContextMenuButton (Button), which is part of docking header. I've had other issues with UI command propagation within UserControls hosted inside AvalonDock, but this one is the easiest to reproduce.

  • Is there a Hypercam for Mac OS X?

    - by mrpwnscroner
    I don't care if it's not free; I switched from PC to Mac recently and I kind of miss Hypercam to record our best moments in games (Halo, Combat Arms, Starcraft, etc) and showing hacks. I tried to use Crossover Pro 8 and 9 and it hasn't worked. If anyone has a solution, let me know. Thanks!

  • I need to build a mini computer lab with 6 PCs

    - by chiurox
    Hello everyone, This weekend I need to build a mini computer lab with 5-6 PCs. The purpose is for a small computer class that will be taking place. They're mostly going to be doing office and daily kind of stuff, so nothing high performance. However, I hope it will last at least for 2 more years. I already have some parts for 2 PCs, one is a P4 3.0 and another is Celeron 2.4GHz, both socket 478. For the other 4 PCs, I'm wondering if I should buy individual parts and put it all together or get workstations like those Dell Optiplex with P4s. To put things into perspective, I am not currently in the US. I'm in South America and prices here are ridiculously. Another really important thing is that I need to share an internet connection between a total of 8 PCs at this place. Right now I only have a crappy wireless router, should I get another one? Or go with switch hub? I'm not experienced in this matter. Thanks guys!

  • Why hasn't functional programming taken over yet?

    - by pankrax
    I've read some texts about declarative/functional programming (languages), tried out Haskell as well as written one myself. From what I've seen, functional programming has several advantages over the classical imperative style: Stateless programs; No side effects Concurrency; Plays extremely nice with the rising multi-core technology Programs are usually shorter and in some cases easier to read Productivity goes up (example: Erlang) Imperative programming is a very old paradigm (as far as I know) and possibly not suitable for the 21st century Why are companies using or programs written in functional languages still so "rare"? Why, when looking at the advantages of functional programming, are we still using imperative programming languages? Maybe it was too early for it in 1990, but today?

    I have noticed that the quality of the images produced by the JPEGEncoder does not match that of other encoders available (i.e. php's built in image compression functions from the gd library) Any explanation ? or hints/workarounds for improving the quality of compressed images by JPEGEncoder ??

  • How can I ensure that JavaScript inserted via AJAX will be executed after the accompanying HTML (als

    - by RenderIn
    I've got portions of pages being replaced with HTML retrieved via AJAX calls. Some of the HTML coming back has JavaScript that needs to be run once in order to initialize the accompanying HTML (setting up event handlers). Since the document has already been loaded, when I replace chunks of HTML using jQuery's .html function, having jQuery(document).ready(function() {...}); doesn't execute since the page loaded long before and this is just a snippet of HTML being replaced. What's the best way to attach event handlers whose code is packaged along with the HTML it's interested in, when that content is loaded via AJAX? Should I just put a procedural block of javascript after the HTML , so that when I insert the new HTML block, jQuery will execute the javascript immediately? Is the HTML definitely in the DOM and ready to be acted upon by JavaScript which is in the same .html call?

  • jQuery AJAX PHP JSON problem

    - by Curro
    Hi Gurus I'm facing the problem of receiving an empty array when I do an AJAX request in the following way: This is the code I'm executing in JavaScript: <script type="text/javascript" src="lib/jquery.js"></script> <script type="text/javascript" src="lib/jquery.json.js"></script> <script type="text/javascript"> $(document).ready(function(){ /* Preparar JSON para el request */ var mJSON = new Object; mJSON.id_consulta = new Array; for (var i=0; i<3; i++){ mJSON.id_consulta[i] = new Object; mJSON.id_consulta[i].id = i; } var sJSON = $.toJSON(mJSON); $.ajax({ type: "POST", url: "getUbicaciones.php", data: sJSON, dataType: "json", contentType: "application/json; charset=utf-8", success: function(respuesta){ alert(respuesta); }, error: function (request,error){ alert("Error: " + request.statusText + ". " + error); } }); }); </script> And this is the code under PHP: <?php /* Decodificar JSON */ $m_decoded = $_POST; print_r($m_decoded); exit; ?> And all I get from this, using Chrome's Developer Tools is an empty array: Array ( ) Any clues on what am I doing wrong? The string sJSON is being encoded correctly, this is what I get when I do an "alert" on that one: {"id_consulta":[{"id":1},{"id":2},{"id":3}]} Thank you everyone in advance!

  • How does polymorphism work in Python?

    - by froadie
    I'm new to Python... and coming from a mostly Java background, if that accounts for anything. I'm trying to understand polymorphism in Python. Maybe the problem is that I'm expecting the concepts I already know to project into Python. But I put together the following test code: class animal(object): "empty animal class" class dog(animal): "empty dog class" myDog = dog() print myDog.__class__ is animal print myDog.__class__ is dog From the polymorphism I'm used to (e.g. java's instanceof), I would expect both of these statements to print true, as an instance of dog is an animal and also is a dog. But my output is: False True What am I missing?

  • How do I enable mod_deflate for PHP files?

    - by DM.
    I have a Liquid Web VPS account, I've made sure that mod_deflate is installed and running/active. I used to gzip my css and js files via PHP, as well as my PHP files themselves... However, I'm now trying to do this via mod_deflate, and it seems to work fine for all files except for PHP files. (Txt files work fine, css, js, static HTML files, just nothing that is generated via a PHP file.) How do I fix this? (I used the "Compress all content" option under "Optimize Website" in cPanel, which creates an .htaccess file in the home directory (not public_html, one level higher than that) with exactly the same text as the "compress everything except images" example on http://httpd.apache.org/docs/2.0/mod/mod_deflate.html) .htaccess file: <IfModule mod_deflate.c> SetOutputFilter DEFLATE <IfModule mod_setenvif.c> # Netscape 4.x has some problems... BrowserMatch ^Mozilla/4 gzip-only-text/html # Netscape 4.06-4.08 have some more problems BrowserMatch ^Mozilla/4\.0[678] no-gzip # MSIE masquerades as Netscape, but it is fine # BrowserMatch \bMSIE !no-gzip !gzip-only-text/html # NOTE: Due to a bug in mod_setenvif up to Apache 2.0.48 # the above regex won't work. You can use the following # workaround to get the desired effect: BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html # Don't compress images SetEnvIfNoCase Request_URI .(?:gif|jpe?g|png)$ no-gzip dont-vary </IfModule> <IfModule mod_headers.c> # Make sure proxies don't deliver the wrong content Header append Vary User-Agent env=!dont-vary </IfModule> </IfModule>

  • Integers in TextNodes w/ Python minidom

    - by PylonsN00b
    I am working on an API using SOAP and WSDL. The WSDL expects integers to come through. I am fairly new to ALL of this, and constructing XML in Python. I have chosen to use minidom to create my SOAP message. So using minidom, to get a value into a node I found I have to do this: weight_node = xml_file.createElement("web:Weight") weight_contents = xml_file.createTextNode(weight) weight_node.appendChild(weight_contents) So say weight needs to go in as an integer and IS an integer. The function is 'createTextNode' does this mean its going to be text, or what I put in there has to be text? Again I am fairly new to all of this. So if what I have explained seems way off base, please speak up.

  • C++ stack for multiple data types (RPN vector calculator)

    - by Arrieta
    Hello: I have designed a quick and basic vector arithmetic library in C++. I call the program from the command line when I need a rapid cross product, or angle between vectors. I don't use Matlab or Octave or related, because the startup time is larger than the computation time. Again, this is for very basic operations. I am extending this program, and I will make it work as an RPN calculator, for operations of the type: 1 2 3 4 5 6 x out: -3 6 -3 (give one vector, another vector, and the "cross" operator; spit out the cross product) The stack must accept 3d vectors or scalars, for operations like: 1 2 3 2 * out: 2 4 6 The lexer and parser for this mini-calculator are trivial, but I cannot seem to think of a good way for creating the internal stack. How would you create a stack of for containing vectors or doubles (I rolled up my own very simple vector class - less than one hundred lines and it does everything I need). How can I create a simple stack which accepts elements of class Vector or type double? Thank you.

  • git-svn: reset tracking for master

    - by digitala
    I'm using git-svn to work with an SVN repository. My working copies have been created using git svn clone -s http://foo.bar/myproject so that my working copy follows the default directory scheme for SVN (trunk, tags, branches). Recently I've been working on a branch which was created using git-svn branch myremotebranch and checked-out using git checkout --track -b mybranch myremotebranch. I needed to work from multiple locations, so from the branch I git-svn dcommit-ed files to the SVN repository quite regularly. After finishing my changes, I switched back to the master and executed a merge, committed the merge, and tried to dcommit the successful merge to the remote trunk. It seems as though after the merge the remote tracking for the master has switched to the branch I was working on: # git checkout master # git merge mybranch ... (successful) # git add . # git commit -m '...' # git svn dcommit Committing to http://foo.bar/myproject/branches/myremotebranch ... # Is there a way I can update the master so that it's following remotes/trunk as before the merge? I'm using git 1.7.0.5, if that's any help.

  • Replace string with incremented value

    - by Andrei
    Hello, I'm trying to write a CSS parser to automatically dispatch URLs in background images to different subdomains in order to parallelize downloads. Basically, I want to replace things like url(/assets/some-background-image.png) with url(http://assets[increment].domain.com/assets/some-background-image.png) I'm using this inside a class that I eventually want to evolve into doing various CSS parsing tasks. Here are the relevant parts of the class : private function parallelizeDownloads(){ static $counter = 1; $newURL = "url(http://assets".$counter.".domain.com"; The counter needs to be reset when it reaches 4 in order to limit to 4 subdomains. if ($counter == 4) { $counter = 1; } $counter ++; return $newURL; } public function replaceURLs() { This is mostly nonsense, but I know the code I'm looking for looks somewhat like this. Note : $this-css contains the CSS string. preg_match("/url/i",$this->css,$match); foreach($match as $URL) { $newURL = self::parallelizeDownloads(); $this->css = str_replace($match, $newURL,$this->css); } }
