  • Why are my bound parameters all identical (using Linq)?

    - by Scott Stafford
    When I run this snippet of code: string[] words = new string[] { "foo", "bar" }; var results = from row in Assets select row; foreach (string word in words) { results = results.Where(row => row.Name.Contains(word)); } I get this SQL: -- Region Parameters DECLARE @p0 VarChar(5) = '%bar%' DECLARE @p1 VarChar(5) = '%bar%' -- EndRegion SELECT ... FROM [Assets] AS [t0] WHERE ([t0].[Name] LIKE @p0) AND ([t0].[Name] LIKE @p1) Note that @p0 and @p1 are both bar, when I wanted them to be foo and bar. I guess Linq is somehow binding a reference to the variable word rather than a reference to the string currently referenced by word? What is the best way to avoid this problem? (Also, if you have any suggestions for a better title for this question, please put it in the comments.) Note that I tried this with regular Linq also, with the same results (you can paste this right into Linqpad): string[] words = new string[] { "f", "a" }; string[] dictionary = new string[] { "foo", "bar", "jack", "splat" }; var results = from row in dictionary select row; foreach (string word in words) { results = results.Where(row => row.Contains(word)); } results.Dump(); Dumps: bar jack splat

  • Wordpress > Exclude specific categories from categories listing

    - by Scott B
    I have created some functional categories that I use to show/hide markup elements. However, when I go to list the legit categories, these show up too, which I would expect. I want to list the legitimate categories and omit others. I need to know how you would do it under two circumstances.... 1) Each category that I want to exclude is preceded by an underscore character in its name. 2) Each category that I want to exclude is NOT preceeded by a special character and I will just provide an ID to the script that handles the exclusion listing.

  • jQuery IE7 on-the-fly images

    - by Scott Evernden
    The simplified version of the problem I am seeing in IE7 can be demonstated using FireBug Lite. On a page loaded with jQuery, I open FireBug Lite (via bookmarket) and I enter the following: image = $('<img src="http://example.com/boofar.jpg" border="12" width="95" height="95" title="Booya">')[0]; and the result echoed is: <img title="Booya" contentEditable="inherit" start="fileopen" loop="1" src="http://example.com/boofar.jpg" border="12"> Where are the width and height attributes? Furthermore, image.width; and image.attributes.width.value; return 0 and "0". Seen this with both jQuery 1.2.6 as well as 1.4.2. It does the right thing in IE8 and FF. Any ideas where those attributes went? Very annoying....

  • 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

  • find nearest match to array of doubles

    - by Scott
    Given the code below, how do I compare a List of objects's values with a test value? I'm building a geolocation application. I'll be passing in longitude and latitude and would like to have the service answer back with the location closest to those values. I started down the path of converting to a string, and formatting the values down to two decimal places, but that seemed a bit too ghetto, and I'm looking for a more elegant solution. public class Location : IEnumerable { public string label { get; set; } public double lat { get; set; } public double lon { get; set; } //Implement IEnumerable public IEnumerator GetEnumerator() { return (IEnumerator)this; } } [HandleError] public class HomeController : Controller { private List<Location> myList = new List<Location> { new Location { label="Atlanta Midtown", lon=33.657674, lat=-84.423130}, new Location { label="Atlanta Airport", lon=33.794151, lat=-84.387228}, new Location { label="Stamford, CT", lon=41.053758, lat=-73.530979}, ... } public static int Main(String[] args) { string inLat = "-80.987654"; double dblInLat = double.Parse(inLat); // here's where I would like to find the closest location to the inLat // once I figure out this, I'll implement the Longitude, and I'll be set }

  • 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 ?>

  • How does Contract.Exists add value?

    - by Scott Bilas
    I am just starting to learn about the code contracts library that comes standard with VS2010. One thing I am running into right away is what some of the contract clauses really mean. For example, how are these two statements different? Contract.Requires(!mycollection.Any(a => a.ID == newID)); Contract.Requires(!Contract.Exists(mycollection, a => a.ID == newID)); In other words, what does Contract.Exists do in practical purposes, either for a developer using my function, or for the static code analysis system?

  • Why Solr admin query page interprets UTF-8 as ISO-8859-1

    - by Scott Chu
    I deploy a war to my Tomcat 6.0.35 on Win7 64bit and when I use full-interface query page (I mean form.jsp) in Solr Admin to query 2 Chinese character (say it's C1C2) , the debug info shows: <lst name="debug"> <str name="rawquerystring">æ°è</str> <str name="querystring">æ°è</str> <str name="parsedquery">NEWSID:æ°è</str> <str name="parsedquery_toString">NEWSID:æ°è</str> ... You can see C1C2 becomes æ°è. I deploy same war file to Tomcat on Linux or on another Win7 64bit of my colleagues' computer, the encoding acts well. Does anyone know why and how can I avoid this problem? Thanks in advance!

  • How to Sort a TreeList in Sitecore 6 in the Source

    - by Scott
    My team uses Sitecore 6 as content management system and then .Net to interface with Sitecore API. In many of our templates we make use of a Treelist. When adding a new item to the selected items Treelist it automatically puts the item at the bottom of the list. In some lists they get very large. In most cases end users would like to see these lists sorted descending by a Date field that is part of the templates that can be added as selected to the Treelist. Programmatically on the .Net side its very easy to handle this using Linq OrderByDescending and all displays great in the site to visitors. What I am trying to figure out is how to get it to display the same in Sitecore Content Editor. I've not found anything from Google search other than there seems to be a SortBy you can specify in the source but I tried this and can't get it to have any effect. Has anyone dealt with this before? Again, main goal is to sort items in a Treelist in the Sitecore Content Editor itself. Thanks for any input anyone has.

  • Allow a new line anywhere in the regex?

    - by Scott Chamberlain
    I am having a find a replace in a bunch of RTF documents, The basic pattern I need is \{(?:\\\*)?\\field\\fldlock\{\\\*\\fldinst ?MERGEFIELD ?((?:\\.*?)?[\w\[\]]+?)(?:\\.*?)?\}(?:\{\\fldrslt\})?\} However I then found out there could potentialy be a newline before each slash, so it turned in to this. \{(?:\s*\\\*)?\s*\\field\s*\\fldlock\s*\{\s*\\\*\s*\\fldinst\s*MERGEFIELD\s*((?:\\.*?)?[\w\[\]]+?(?:\s*\\.*?)?)?\s*\}(?:\s*\{\s*\\fldrslt\s*\})?\s*\} But then I hit this it fails fees totaling $\protect {\field\fldlock{\*\fldinst MERGEFIELD ENTEROUTSTANDINGVETERINARYF EES}}\plain\f0\fs24\prot Is there way have to have it match a new line anywhere in the search too without adding (?:\r?\n)? everywhere? EDIT To clear up confusion on the new lines. I need to keep the newlines in the document, I only want to remove the newlines if they are inside my match, so in the final example I posted it should replace fees totaling $\protect {\field\fldlock{\*\fldinst MERGEFIELD ENTEROUTSTANDINGVETERINARYF EES}}\plain\f0\fs24\prot with fees totaling $\protect ENTEROUTSTANDINGVETERINARYFEES\plain\f0\fs24\prot

  • 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="****"/>

  • 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.

  • GhostScript PDF Merging (Losing Editable Fields)

    - by Scott
    I'm using GhostScript to merge to PDFs into one PDF. One of the PDFs has textbox fields (editable fields) that I created in Adobe Acrobat Pro 9. When I merge these two PDFs with GhostScript I lose the textbox fields. Is there any way to merge these files (using GS or some other free linux software) that keeps the textbox fields intact?

  • 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); } }

  • 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,

  • Could someone explain __declspec(naked) please?

    - by Scott
    I'm looking into porting a script engine written for Windows to Linux; it's for Winamp's visualization platform AVS. I'm not sure if it's even possible at the moment. From what I can tell the code is taking the addresses of the C functions nseel_asm_atan and nseel_asm_atan_end and storing them inside a table that it can reference during code execution. I've looked at MS's documentation, but I'm unsure what __declspec(naked) really does. What is prolog and epilog code mentioned in the documentation? Is that related to Windows calling conventions? Is this portable? Know of any Linux-based examples using similar techniques? static double (*__atan)(double) = &atan; __declspec ( naked ) void nseel_asm_atan(void) { FUNC1_ENTER *__nextBlock = __atan(*parm_a); FUNC_LEAVE } __declspec ( naked ) void nseel_asm_atan_end(void) {}

  • Should I still use querystrings for page number, etc, when using ASP.NET 4 URL Routing?

    - by Scott
    I am switching from Intelligencia's UrlRewriter to the new web forms routing in ASP.NET 4.0. I have it working great for basic pages, however, in my e-commerce site, when browsing category pages, I previously used querystrings that were built into my pager control to control paging. An old url (with UrlRewriting) would be: http://www.mysite.com/Category/Arts-and-Crafts_17 I now have a MapPageRoute defined in global.asax as: routes.MapPageRoute("category-browse", "Category/{name}_{id}", ~/CategoryPage.aspx"); This works great. Now, somebody clicks to go to page 2. Previously I would have just tacked on ?page=2 as the querystring. Now, How do I handle this using web forms routing? I know I can do something like: http://www.mysite.com/Category/Arts-and-Crafts_17/page/2 But in addition to page, I can have filters, age ranges, gender, etc. Should I just keep defining routes that handle these variables, or should I continue using querystrings and can I define a route that allows me to use my querstrings like before?

  • How do you make a WiX project build when dependent files have changes?

    - by Scott Langham
    Hi, I've adopted a Visual Studio solution that contains a number WiX projects. We build the solution from an MsBuild script to generate the product's installer msi. The problem I'm experiencing is that if I build (and don't rebuild), even if exe's and dll's get updated that need to be put in the installer, the WiX build system doesn't seem to detect this and skips building the installer as it thinks it's already up to date. How do I work out what the dependencies are that are needed to build a WiX project, and how do I tell the Wix build system to watch out for them changing so it knows to build instead of skip?

  • 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>

  • 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>

  • Adding fields to Django form dynamically (and cleanly)

    - by scott
    Hey guys, I know this question has been brought up numerous times, but I'm not quite getting the full implementation. As you can see below, I've got a form that I can dynamically tell how many rows to create. How can I create an "Add Row" link that tells the view how many rows to create? I would really like to do it without augmenting the url... # views.py def myView(request): if request.method == "POST": form = MyForm(request.POST, num_rows=1) if form.is_valid(): return render_to_response('myform_result.html', context_instance=RequestContext(request)) else: form = MyForm(num_rows=1) return render_to_response('myform.html', {'form':form}, context_instance=RequestContext(request)) # forms.py class MyForm(forms.Form): def __init__(self, *args, **kwargs): num_rows = kwargs.pop('num_rows',1) super(MyForm, self).__init__(*args, **kwargs) for row in range(0, num_rows): field = forms.CharField(label="Row") self.fields[str(row)] = field # myform.html http://example.com/myform <form action="." method="POST" accept-charset="utf-8"> <ul> {% for field in form %} <li style="margin-top:.25em"> <span class="normal">{{ field.label }}</span> {{ field }} <span class="formError">{{ field.errors }}</span> </li> {% endfor %} </ul> <input type="submit" value="Save"> </form> <a href="ADD_ANOTHER_ROW?">+ Add Row</a>
