  • what is this operator called and what is it used for <=>

    - by Scott
    I recently came across this magical operator when digging into Groovy: <= Groovy has really made me happy with elvis operators ?. and ?: which I use constantly now and very much wish were in Java. With this new operator, I have only found this reference. It seems to make comparators much easier. My question is how does it handle null values and how does it compare non Comparable object. Does this operator have a name, I couldn't find it Googling.

  • Changing the cursor in WPF sometimes works, sometimes doesn't

    - by Scott
    On several of my usercontrols, I change the cursor by using this.Cursor = Cursors.Wait; when I click on something. Now I want to do the same thing on a WPF page on a button click. When I hover over my button, the cursor changes to a hand, but when I click it, it doesn't change to the wait cursor. I wonder if this has something to do with the fact that it's a button, or because this is a page and not a usercontrol? This seems like weird behavior.

  • Windows: Does something temporarily grab the com ports on startup?

    - by Tim
    I have a WPF/C# app that is launched as part of the "Startup" group on a Windows Embedded Standard machine. One of the first things the app does (in its static App() method) is create a new SerialPort object for COM1. COM1 is a hardwired serial port, not a USB virtual port or anything like that. My problem is that every so often (maybe 1 out of 12) on startup, I get an exception: System.UnauthorizedAccessException: Access to the port 'COM1' is denied. There are no other applications using this port. Also, when I relaunch the app following this error, it grabs the port just fine. It's as if the com port isn't ready/set up for my app sometimes. I'm clueless on this one! Any insight is appreciated! UPDATE: I added a call to SerialPort.GetPortNames() and printout all available ports before attempting to open the port. In the failure case COM1 is indeed THERE! So, it's not that the port isn't ready. It looks like something in Windows is actually grabbing the port temporarily and blocking me.

  • How many rewrite rules should I expect to manage?

    - by Scott Ackerson
    I'm dealing with a hosting team that is fairly skiddish of managing many rewrite rules. What are your experiences with the number of rules your sites are currently managing? I can see dozens (if not more) coming up as the site grows and contracts and need to set expectations that this isn't out of the norm. Thanks

  • Wordpress how to retrieve the post id once its been reset in the page

    - by Scott B
    I'm working with a script in which the postid of the page has been reset via a script include. How can I retrieve the actual true post id and reset its value once it has been changed via script? Here is the script that I'm referring to. Somewhere in there, the postid is being reset so that the page's the_content() call is no longer pulling the current page being viewed. <?php //$featpages = get_option('woo_slider_pages_landing'); $featpages = '579,584,537'; $featarr=split(",",$featpages); $featarr = array_diff($featarr, array("")); $i = 1; foreach ( $featarr as $featured_tab ) { query_posts('page_id=' . $featured_tab); while (have_posts()) : the_post(); ?> <div class="featured-slide" id="slide-<?php echo $i; $i++; ?>" <?php if($i >=3 ){echo 'style="display:none"';} ?>> <div class="text"> <h2><?php if ( get_post_meta($post->ID, "page_desc", $single = true) <> "" ) { echo get_post_meta($post->ID, "page_desc", $single = true); } else { the_title(); } ?></h2> <p><?php if ( get_post_meta($post->ID, "page_excerpt", $single = true) <> "" ) { echo get_post_meta($post->ID, "page_excerpt", $single = true); } else { the_excerpt(); } ?></p> <?php if ( get_post_meta($post->ID, "link_text", $single = true) <> "" and get_post_meta($post->ID, "link_link", $single = true) <> "" ) { ?> <p><a href="<?php echo get_post_meta($post->ID, "link_link", $single = true); ?>" title="<?php echo get_post_meta($post->ID, "link_text", $single = true); ?>"><?php echo get_post_meta($post->ID, "link_text", $single = true); ?></a></p> <?php } ?> </div><!-- /.text --> <?php if ( get_post_meta($post->ID, "image", $single = true) <> "" ) { ?> <div class="image"> <img src="<?php echo get_post_meta($post->ID, "image", $single = true); ?>" alt="<?php the_title(); ?>" class="featured" /> </div><!-- /.image --> <?php } ?> </div><!-- /.featured-slide --> <?php endwhile; } //endforeach ?>

  • Installing Security Certifcates for all users on a Windows XP machine

    - by scott-thornton
    Hi, I am required to install two security certifcates on user's PC's to allow them to connect to a certain Australian Government website to perform searchs. I can perform this manually (via Certifcate Import Wizard) when the user has logged into the machine, however when a different user logs in, the certifcates need to be re-installed for that user as well. Q1. Can certifcates ( the file extension is .p12) be installed in such a way that any user using the PC can use the certifcates? Q2. Can the installation of the certifcates be automated ( via SMS? ) to install both certifcates and enter the requried password? Thanks,

  • WPF: how to make normal listbox left-drag-select behavior use middle mouse instead?

    - by Scott Bilas
    I'm building a special listbox control that our designers want customized in some tweaky ways. One thing they want to see is that the middle button-drag does what the left button-drag normally does (we are repurposing left-drag to other things). So it needs the two key features that left-drag does in a ListBox default implementation: While holding down the button and dragging, the selection starts where I click down and extends to where I drag. While dragging outside the listbox region, it scrolls if there is scrollable space in that direction. Before I go an duplicate this functionality by hand, is there any easy way to fool ListBox into thinking it's getting left-mouse drag events but instead is getting middle-mouse?

  • Convert Array to Multidimensional Array

    - by Tim
    I like to convert a single array into a multidimensional array. This is what I get have web scraping a page, except it is not the end result that I am looking for.

  • transferring binary files between systems

    - by tim
    Hi guys I'm trying to transfer my files between 2 UNIX clusters, the data is pure numeric (vectors of double) in binary form. Unfortunately one of the systems is IBM ppc997 and the other is AMD Opteron, It seems the format of binary numbers in these systems are different. I have tried 3 ways till now: 1- Changed my files to ASCII format (i.e. saved a number at each line in a text file), sent them to the destination and changed them again to binary on the target system (they both are UNIX, no end of line character difference??!) 2- Sent pure binaries to the destination 3- used uuencode sent them to the destination and decoded them Unfortunately any of these methods does not work (my code in the destination system generates garbage, while it works on the first system, I'm 100% sure the code itself is portable). I don't know what else I can do? Do you have any idea? I'm not a professional, please don't use computer scientists terminology! And: my codes are in C, so by binary I mean a one to one mapping between memory and hard disk. Thanks

  • Copy Data from One SQL Server Table to Other in Same Database Without Specifying Columns

    - by Scott
    In SQL Server there is the ability to INSERT all of the data from one table into another using the following statement: INSERT INTO TABLE1 SELECT * FROM TABLE2 When running this on a table with an identity column, even though we have run the command SET IDENTITY_INSERT TABLE1 ON, we get the error: An explicit value for the identity column in table can only be specified when a column list is used and IDENTITY_INSERT is ON This implies that we would have to list off all of the columns within the INSERT in order for this to work properly. In the situation that we are in, we do not have access to the column names, only the list of the tables we need to copy over. Is there any way to get around this limitation?

  • Subitems are not all added to a list view in C# using XmlNodeList

    - by tim
    I'm working on extracting data from an RSS feed. In my listview (rowNews), I've got two columns: Title and URL. When the button is clicked, all of the titles of the articles are showing up in the title column, but only one URL is added to the URL column. I switched them around so that the URLs would be added to the first column and all of the correct URLs appeared... leading me to think this is a problem with my listview source (it's my first time working with subitems). Here's the original, before I started experimenting with the order: private void button1_Click(object sender, EventArgs e) { XmlTextReader rssReader = new XmlTextReader(txtUrl.Text); XmlDocument rssDoc = new XmlDocument(); rssDoc.Load(rssReader); XmlNodeList titleList = rssDoc.GetElementsByTagName("title"); XmlNodeList urlList = rssDoc.GetElementsByTagName("link"); ListViewItem lvi = new ListViewItem(); for (int i = 0; i < titleList.Count; i++) { rowNews.Items.Add(titleList[i].InnerXml); } for (int i = 0; i < urlList.Count; i++) { lvi.SubItems.Add(urlList[i].InnerXml); } rowNews.Items.Add(lvi); }

  • Leaving SQL Management open on the internet

    - by Tim Fraud
    I am a developer, but every so often need access to our production database -- yeah, poor practice, but anyway... My boss doesn't want me directly on the box using RDP, and so we decided to just permit MS SQL Management Console access so that I can do my tasks. So right now we have the SQL box somewhat accessible on the internet (on port 1433 if I am not mistaken), which opens a security hole. But I am wondering, how much of an uncommon practice is this, and what defaults should I be concerned about? We use MSSQL2008 and I created an account that has Read-Only access, because my production tasks only need that. I didn't see any unusual default accounts with default passwords on the system, so I would be interested to hear your take. (And of-course, is there a better way?)

  • How to create GUI as inner class with WindowBuilder

    - by Tim Kemp
    I would like to use WindowBuilder in Eclipse to construct Swing GUIs. The JPanels I need to build will be inner classes in a non-GUI wrapper, like so: public class MyWrapper extends MyBaseClass { ... class MyPanel extends JPanel { ... } } So my question is this: can I construct MyPanel using WindowBuilder? If so, how should I set it up? If anyone is interested, the wrapper is an abstract base class which the plug-ins I am developing for my app must extend; deployment concerns mean that it's not really practical to put the GUIs in a separate JAR either so I pretty much have to do it this way. My current workflow, which is awful, is to build the GUI in NetBeans and paste the entire generated class into Eclipse where I connect it up to the methods in my wrapper. I am very hopeful that WindowBuilder will let me work more reliably and efficiently if I can trick it into generating code in MyPanel, not MyWrapper. Thanks

  • How do I open a web browser from C#? Process.Start() isn't working?

    - by Scott Whitlock
    I have a URL and I want to launch it in the default browser. I've tried two methods: Process.Start("http://stackoverflow.com"); ... and the one detailed in this other question using ShellExecute. In both cases I get the error: Windows cannot find 'http://stackoverflow.com'. Make sure you typed the name correctly, and then try again. It shouldn't be trying to open it as a file though... from what I understand, it should recognize it as a URL and open it in the default browser. What am I missing? By the way: OS = Vista, and .NET = 3.5

  • JQuery not removing added element

    - by Scott
    What I want to do is add and remove list items. I have got it to add new items to the list and I can remove existing ones but not the ones that have been added. It seem like it would work but it doesn't. Any help would be appreciated! Here the code: JQuery: <script type="text/javascript"> $(function(){ $('a#add').click(function(){ $('<li><a href="#" id="remove">--</a>List item</li>').appendTo('ul#list'); }); $('a#remove').click(function(){ $(this).parent().remove(); }); }); </script> HTML: <a href="#" id="add">Add List Item</a> <ul id="list"> <li><a href="#" id="remove">--</a> List item</li> <li><a href="#" id="remove">--</a> List item</li> <li><a href="#" id="remove">--</a> List item</li> <li><a href="#" id="remove">--</a> List item</li> </ul>

  • Help converting subquery to query with joins

    - by Tim
    I'm stuck on a query with a join. The client's site is running mysql4, so a subquery isn't an option. My attempts to rewrite using a join aren't going too well. I need to select all of the contractors listed in the contractors table who are not in the contractors2label table with a given label ID & county ID. Yet, they might be listed in contractors2label with other label and county IDs. Table: contractors cID (primary, autonumber) company (varchar) ...etc... Table: contractors2label cID labelID countyID psID This query with a subquery works: SELECT company, contractors.cID FROM contractors WHERE contractors.complete = 1 AND contractors.archived = 0 AND contractors.cID NOT IN ( SELECT contractors2label.cID FROM contractors2label WHERE labelID <> 1 AND countyID <> 1 ) I thought this query with a join would be the equivalent, but it returns no results. A manual scan of the data shows I should get 34 rows, which is what the subquery above returns. SELECT company, contractors.cID FROM contractors LEFT OUTER JOIN contractors2label ON contractors.cID = contractors2label.cID WHERE contractors.complete = 1 AND contractors.archived = 0 AND contractors2label.labelID <> 1 AND contractors2label.countyID <> 1 AND contractors2label.cID IS NULL

  • Edit Settings in web.config

    - by Scott Selby
    I didn't know how to title this question - I am making a request to PayPal's Express Payment API. I am using their dll that helps make the request and parse the response. The instructions for their code to work is to add you authorization credentials in the web.config file. I have done so. My problem is that I want to be able to edit these credentials that are being set dynamically ( probably get from SQL ) because we are going to allow different users to enter their API credentials. Sending the request to PayPal looks like this Dim wrapper As New SetExpressCheckoutReq() wrapper.SetExpressCheckoutRequest = request Dim service As New PayPalAPIInterfaceServiceService() Dim setECResponse As SetExpressCheckoutResponseType = service.SetExpressCheckout(wrapper) There's not much room in there to edit the header of the request , because PayPalAPIInterfaceServiceService() is defined in their dll and applies its own header based on the credentials in the web.config. So, my question is , is there a way to point in the web.config to another location when it looks in web.config? I'm not to sure this is possible , also is there any way to edit the header of a request that is defined in a dll without changing the dll (to stay pci compliant) The line in the web.config is here: <account apiUsername="****" apiPassword="****" apiSignature="****"/>

  • Using an observer within an Engine

    - by Tim
    I've created an Engine which is basically used for all of our projects. Now what I want to do is add a before_create callback to all of the models in this Engine. After some searching I found out that an observer is the way to go. So, I've created this observer: class AuthObserver < ActiveRecord::Observer def before_create( record ) p record end end And now I need to add it to the application, but of course in my Engine there is no such file as application.rb. What I tried is adding it to an initializer located in /config/initializers/observers.rb Like so: Rails.application.config.active_record.observers = :auth_observer But this doesn't work, and it throws no errors. Anybody out here has experience using an observer inside an engine? Thanks a lot!

  • How to determine if a target will be executed?

    - by Scott Langham
    Hi, I'm writing an msbuild file and have something like this: <ValidateDependsOn>$(ValidateDependsOn);ValidateA</ValidateDependsOn> <ValidateDependsOn>$(ValidateDependsOn);ValidateB</ValidateDependsOn> <Target Name="BuildA"> <!-- stuff --> </Target> <Target Name="BuildB"> <!-- stuff --> </Target> <Target Name="ValidateA"> <Error /> <!-- check properties and machine environment are suitable to run BuildA --> </Target> <Target Name="ValidateB"> <Error /> <!-- check properties and machine environment are suitable to run BuildB --> </Target> Builds can take a while. Originally we had the Build steps depending on the Validate steps, but sometimes a validate step wouldn't run until the middle of the build and you would have wasted time getting there. So, we moved the validate steps to the start by using the ValidateDependsOn pattern to insert the targets to run up front. The problem now though is that sometimes during a build BuildB may not actually run, and this means I don't need and in fact, don't want ValidateB to run. Is there any way I can selectively update ValidateDependsOn by conditionally knowing which targets will actually be run? I'm looking for something equivalent to: <ValidateDependsOn Condition="TargetWillRun(BuildB)">$(ValidateDependsOn);ValidateB</ValidateDependsOn>

  • info about intel Cos embedded i86 os

    - by Tim Williscroft
    I've got some old Intel printer (Etherexpress XL ) print servers and they seem to be running an Intel OS called Cos aka Intel Client Os i86 I've found out that much just looking in the update files from Intel. It was at least partly written in C. How do I make a custom software image Intel Cos's boot loader will understand ? I know a host PC xmodem's the image to the client device, and I was wondering if anyone had already either reverse-engineered this or had original info ? or is my only recousre to reverse engineer the update file format ?

  • before_filter not inheriting from parent controller correctly?

    - by Scott
    Sorry if this may be a stupid question but I'm unable get my filters to inherit the way the Rails 3 documentation is saying it should. Specifically I have an Admin controller that was generated via: rails generate controller admin I added only a single action to the admin controller, the before filter & the private filter method class AdminController < ApplicationController before_filter require_admin_creds def index end private def require_admin_creds unless current_user && current_user.admin? flash[:error] = ... redirect_to .... end end end I next then created my nested resources under the admin section with: rails generate scaffold admin/model While my admin index is indeed getting the filter, the admin/model index (or any other actions) are not. What is happening under the hood here that I must have excluded? Thanks in advance.

  • WordPress update_post_meta values. Delete when empty or just test for ""?

    - by Scott B
    My function below, will take the values from my custom meta fields (after a post has been edited, and save or publish has been clicked) and update or insert the posted meta values. However, if the user leaves this field blank, I believe I want to delete the meta altogether (so I can test for its presence and display accordingly vs just checking for ""). For example, one of my meta options gives the user the ability to add a Custom title to their post, which when present, will populate the page's tag. However, if the field is left empty, I want to default the tag to the_title(), which is simply the Post title used to identify the page/post. Since I'm not deleting the meta on save, its always present after the first time a user enters something in there, get_post_meta($post-ID,'MyCustomTitle', true) is always true. Further, they cannot blank it out by clearing the title field and hitting publish. What am I missing in the save in order to clear the value to "" when the user clears the field? if ($_POST['MyCustomTitle']) { update_custom_meta($postID, $_POST['MyCustomTitle'], 'MyCustomTitle'); } function update_custom_meta($postID, $newvalue, $field_name) { // To create new meta if(!get_post_meta($postID, $field_name)){ add_post_meta($postID, $field_name, $newvalue); }else{ // or to update existing meta update_post_meta($postID, $field_name, $newvalue); } }

  • Listing the content of a tar file or a directory only down to some level

    - by Tim
    I wonder how to list the content of a tar file only down to some level? I understand tar tvf mytar.tar will list all files, but sometimes I would like to only see directories down to some level. Similarly, for the command ls, how do I control the level of subdirectories that will be displayed? By default, it will only show the direct subdirectories, but not go further.

  • AJAX Autocomplete appears at a random vertical position, not touching the textbox

    - by Tim
    Hi, I am using the AJAX Autocomplete extender for ASP.NET 2. Everything works fine...I am calling a webservice which gets me the values to fill the drop down with after 3 letters are typed into certain es. I have set the maxheight attribute and am using a scrollbar in case there are more entries than would fit that height. However, I notice that in some cases, the drop down appears at a random position on the screen, i.e. rather than connected to the relevant textbox, sometimes it appears with its entries above the textbox, not touching it at all. Sometimes it would have just one entry and it would appear in the middle of the screen vertically above the textbox it is associated to. Is there a reason why this is happening?
