  • User Control not loading based on location

    - by mwright
    I have an ASP.net MVC solution that uses nested master pages to load content. On the first Master page I load a header, then have the Content Placeholder, and then load a footer. This master page is referenced by another master page which adds some additional information based on the user being logged in or not. When I load a page that references these master pages, the header loads, but the footer does not. If I move the footer up above the Content Place Holder it loads into the page. Any ideas why this might be the case? The code for the master page that contains the footer is as follows: <%@ Master Language="C#" Inherits="System.Web.Mvc.ViewMasterPage" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title> <asp:ContentPlaceHolder ID="TitleContent" runat="server" /> </title> </head> <body> <div class="header"> <% Html.RenderPartial("Header"); %> </div> <div> <asp:ContentPlaceHolder ID="MainContent" runat="server"> </asp:ContentPlaceHolder> </div> <div class="footer"> <% Html.RenderPartial("Footer"); %> </div> </body> </html>

  • Grayscale image with colored spotlight in JavaFX

    - by DaUltimateTrooper
    I need a way to have a gray scale image in an ImageView and on mouse moved if the cursor position is in the ImageView bounds to show a colored spotlight on the mouse position. I have created a sample to help you understand what I need. This sample negates the colors of a colored image on the onMouseMoved event. package javafxapplication3; import javafx.scene.effect.BlendMode; import javafx.scene.Group; import javafx.scene.image.Image; import javafx.scene.image.ImageView; import javafx.scene.input.MouseEvent; import javafx.scene.paint.Color; import javafx.scene.paint.RadialGradient; import javafx.scene.paint.Stop; import javafx.scene.Scene; import javafx.scene.shape.Circle; import javafx.stage.Stage; var spotlightX = 0.0; var spotlightY = 0.0; var visible = false; var anImage = Image { url: "{__DIR__}picture1.jpg" } Stage { title: "Spotlighting" scene: Scene { fill: Color.WHITE content: [ Group { blendMode: BlendMode.EXCLUSION content: [ ImageView { image: anImage onMouseMoved: function (me: MouseEvent) { if (me.x > anImage.width - 10 or me.x < 10 or me.y > anImage.height - 10 or me.y < 10) { visible = false; } else { visible = true; } spotlightX = me.x; spotlightY = me.y; } }, Group { id: "spotlight" content: [ Circle { visible: bind visible translateX: bind spotlightX translateY: bind spotlightY radius: 60 fill: RadialGradient { centerX: 0.5 centerY: 0.5 stops: [ Stop { offset: 0.1, color: Color.WHITE }, Stop { offset: 0.5, color: Color.BLACK }, ] } } ] } ] }, ] }, } I am a total newbie what can I say...

  • How to select the first property with unknown name and first item from array in JSON

    - by Oscar Godson
    I actually have two questions, both are probably simple, but for some odd reason I cant figure it out... I've worked with JSON 100s of times before too! but here is the JSON in question: {"69256":{ "streaminfo":{ "stream_ID":"1025", "sourceowner_ID":"2", "sourceowner_avatar":"http:\/\/content.nozzlmedia.com\/images\/sourceowner_avatar2.jpg", "sourceownertype_ID":"1", "stream_name":"Twitter", "streamtype":"Social media" "appsarray":[] }, "item":{ "headline":"Charboy", "main_image":"http:\/\/content.nozzlmedia.com\/images\/author_avatar173212.jpg", "summary":"ate a tomato and avocado for dinner...", "nozzl_captured":"2010-05-12 23:02:12", "geoarray":[{ "state":"OR", "county":"Multnomah", "city":"Portland", "neighborhood":"Downtown", "zip":"97205", "street":"462 SW 11th Ave", "latitude":"45.5219", "longitude":"-122.682" }], "full_content":"ate a tomato and avocado for dinner tonight. such tasty foods. just enjoyable.", "body_text":"ate a tomato and avocado for dinner tonight. such tasty foods. just enjoyable.", "author_name":"Charboy", "author_avatar":"http:\/\/content.nozzlmedia.com\/images\/author_avatar173212.jpg", "fulltext_url":"http:\/\/twitter.com\/charboy\/statuses\/13889868936", "leftovers":{ "twitter_id":"tag:search.twitter.com,2005:13889868936", "date":"2010-05-13T02:59:59Z", "location":"iPhone: 45.521866,-122.682262" }, "wordarray":{ "0":"ate", "1":"tomato", "2":"avocado", "3":"dinner", "4":"tonight", "5":"tasty", "6":"foods", "7":"just", "8":"enjoyable", "9":"Charboy", "11":"Twitter", "13":"state:OR", "14":"county:Multnomah, OR", "15":"city:Portland, OR", "16":"neighborhood:Downtown", "17":"zip:97205" } } } } Question 1: How do I loop through each item (69256) when the number is random? e.g. item 1 is 123, item2 is 646? Like, for example, a normal JSON feed would have something like: {'item':{'blah':'lorem'},'item':{'blah':'ipsum'}} the JS would be like console.log(item.blah) to return lorem then ipsum in a loop How do I do it when i dont know the first item of the object? Question 2: How do I select items from the geoarray object? I tried: json.test.item.geoarray.latitude and json.test.item.geoarray['latitude']

  • PHP ZipArchive Empty in IE

    - by Jesse Bunch
    Hi, I am using PHP's ZipArchive class to create a zip file containing photos and then serve it up to the browser for download. Here is my code: /** * Grabs the order, packages the files, and serves them up for download. * * @param string $intEntryID * @return void * @author Jesse Bunch */ public static function download_order_by_entry_id($intUniqueID) { $objCustomer = PhotoCustomer::get_customer_by_unique_id($intUniqueID); if ($objCustomer): if (!class_exists('ZipArchive')): trigger_error('ZipArchive Class does not exist', E_USER_ERROR); endif; $objZip = new ZipArchive(); $strZipFilename = sprintf('%s/application/tmp/%s-%s.zip', $_SERVER['DOCUMENT_ROOT'], $objCustomer->getEntryID(), time()); if ($objZip->open($strZipFilename, ZIPARCHIVE::CREATE) !== TRUE): trigger_error('Unable to create zip archive', E_USER_ERROR); endif; foreach($objCustomer->arrPhotosRequested as $objPhoto): $filename = PhotoCart::replace_ee_file_dir_in_string($objPhoto->strHighRes); $objZip->addFile($filename,sprintf('/press_photos/%s-%s', $objPhoto->getEntryID(), basename($filename))); endforeach; $objZip->close(); header('Last-Modified: '.gmdate('D, d M Y H:i:s', filemtime($strZipFilename)).' GMT', TRUE, 200); header('Cache-Control: no-cache', TRUE); header('Pragma: Public', TRUE); header('Expires: ' . gmdate('D, d M Y H:i:s', time()) . ' GMT', TRUE); header('Content-Length: '.filesize($strZipFilename), TRUE); header('Content-disposition: attachment; filename=press_photos.zip', TRUE); header('Content-Type: application/octet-stream', TRUE); ob_start(); readfile($strZipFilename); ob_end_flush(); exit; else: trigger_error('Invalid Customer', E_USER_ERROR); endif; } This code works really well with all browsers but IE. In IE, the file downloads correctly, but the zip archive is empty. When trying to extract the files, Windows tells me that the zip archive is corrupt. Has anyone had this issue before?

  • How to access Youtube_it ruby query results?

  • questions about using svn

    - by ajsie
    i have set up a svn repository in a remote ubuntu server using webdav (http://ip/svn). but i have some questions: should i create one svn repository for each project folder? so i should use "svnadmin create" 5 times for 5 projects? or should i import them to seperate folders in the svn repository? should i after i have created a svn repo, import one project folder into it with "svn import" and then DELETE my original local folder thus only having it in the svn repo in the remote ubuntu server? is this safe or should i still have a local copy for some reason (cause i wont work in that one)? i use netbeans to check out projects from svn repo, then i edit the files and commit the changes. but how should i do to update the live web server content (in /var/www)? should i in my ubuntu server use "svn checkout" and check it out to /var/www or should i use netbeans to check out to a local folder and then upload the files to /var/www with ftp or webdav (and which one of them should i use)? so i got a svn repo and lets say 4 programmers are working with it, checking out and commiting. how do i check what is happening in the repo, which one made which changes, and all the changes from day 1 to day 213? does netbeans/eclipse letting me see this kind of information or do i download another application for it? i should have one svn user for each programmer in the ubuntu server? is this accomplished by using "htpasswd" 4 times for 4 programmers? how do i couple all these users to same group so that i could modify file access specific for the svn group and all its members?

  • WebKit and Opera won't load from this server when it's in a frame

    - by crimson_penguin
    This site loads fine in Firefox, but in WebKit browsers (Safari and Google Chrome) it won't load the frame, and in Opera I get this error: "The Web site does not permit its content to be displayed in a frame. It must be displayed in a separate window.". I don't expect to be able to actually fix this, as I don't have control over the frames page (only the content of the frame), but my question is: why? The content of the frame loads fine by itself, and saving the frames page and changing the src of the frame to http://w3.org/ loads fine. I did a bit of searching based on the Opera error, and it seemed to suggest it had to do with redirecting. That URL does indeed redirect, but if I change it to http://mini.milli.no/tonje/main (which doesn't redirect), it still doesn't work. Even Apache directory listings don't work - which to me suggests it's server related. But how can a server do that? To be total clear, I'm using Mac OS X 10.6.3, and I tested with Safari 4.0.5, Chrome 5.0.375.55, Opera 10.53, and Firefox 3.6.3. Basically, the newest of all of those things currently.

  • nginx error: (99: Cannot assign requested address)

    - by k-g-f
    I am running Ubuntu Hardy 8.04 and nginx 0.7.65, and when I try starting my nginx server: $ sudo /etc/init.d/nginx start I get the following error: Starting nginx: [emerg]: bind() to IP failed (99: Cannot assign requested address) where "IP" is a placeholder for my IP address. Does anybody know why that error might be happening? This is running on EC2.

  • Two way sync with rsync

    - by mwm
    I have a folder a/ and a remote folder A/. I now run something like this on a Makefile: get-music: rsync -avzru server:/media/10001/music/ /media/Incoming/music/ put-music: rsync -avzru /media/Incoming/music/ server:/media/10001/music/ sync-music: get-music put-music when I make sync-music, it first gets all the diffs from server to local and then the opposite, sending all the diffs from local to server. This works very well only if there are just updates or new files on the future. If there are deletions, it doesn't do anything. In rsync there is --delete and --delete-after options to help accomplish what I want but thing is, it doesn't work on a 2-way-sync. If I want to delete server files on a syn, when local files have been deleted, it works, but if, for some reason (explained after) I have some files that aren't in the server but exist locally and they were deleted, I want locally to remove them and not server copied (as it happens). Thing is I have 3 machines in context: desktop notebook home-server So, sometimes, server will have files that were deleted with a notebook sync, for example and then, when I run a sync with my desktop (where the deleted server files still exist on) I want these files to be deleted and not to be copied again to the server. I guess this is only possible with a database and track of operations :P Any simple solutions? Thank you.

  • Flex: How to access movieclips within an imported swf

    - by squared
    Hello, I have imported a swf (not created with Flex, i.e. non-framework) into a Flex application. Once loaded, I would like to access movieclips within that imported swf. Looking at Adobe's docs (http://livedocs.adobe.com/flex/3/html/help.html?content=controls_15.html), it seems straightforward; however, their examples are between a Flex app and an imported swf (created with Flex). Like their example, I'm trying to use the SystemManager to access the imported swf's content; however, I receive the following error: TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::MovieClip@58ca241 to mx.managers.SystemManager. Is this error occurring because I'm importing a non-framework swf into a framework swf? Thanks in advance for any assistance. Code: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:SWFLoader source="assets/test.swf" id="loader" creationComplete="swfLoaded()" /> <mx:Script> <![CDATA[ import mx.managers.SystemManager; [Bindable] public var loadedSM:SystemManager; private function swfLoaded():void { loadedSM = SystemManager(loader.content); } ]]> </mx:Script> </mx:Application>

  • ASP.NET MVC WAP, SharePoint Designer and SVN

    - by David Lively
    All, I'm starting a new ASP.NET MVC project which requires some content management capabilities. The people who will be managing the content prefer to use SharePoint Designer (successor to FrontPage) to modify content. I'd like to allow them to keep doing that. The issues are: Since I'd like this to be a WAP, not a website project, how can I allow them to see their changes in action without requiring them to have Visual Studio on their local machines? Can I specify a "default" action for a controller so that given a url like /products/new_view_here Can I let them save pages (views) and see them in the browser without having to go through the check-in/build/deploy process? I'd like their changes to be stored in SVN; SharePoint designer seems to only support Visual SourceSafe (ugh) directly. The ideas I've come up with so far are Write an HTTP handler that implements the FrontPage Server Extensions protocol. This sounds time consuming, but I haven't yet looked at the protocol spec. However, it would allow me to perform whatever operations I want on the server side, including checking files into SVN. Ditch the WAP in favor of a website project. I do not like having the source present on the server, however. Also, will MVC work in a website project? Surely someone has tackled this problem before?

  • I am totally unable to add a fileTree (JQuery fileTree addon) to my asp.net page

    - by Gadgetsan
    okay, so i have an asp.net (C#) application and i want to add a list of file and folders on the page, so i figured i should use JQuery fileTree (http://abeautifulsite.net/2008/03/jquery-file-tree/#download) but now i am totally unable to display the file list. I initialise the page this way: Site.Master: <link rel="stylesheet" type="text/css" href="../../Content/superfish.css" media="screen"> <link href="../../Content/jqueryFileTree.css" rel="stylesheet" type="text/css" /> <script src="../../Scripts/jquery-1.4.1.min.js" type="text/javascript"></script> <script src="../../Scripts/jquery.easing.1.3.js" type="text/javascript"></script> <script src="../../Scripts/jqueryFileTree.js" type="text/javascript"></script> <script src="../../Scripts/JqueryUI/js/jquery-ui-1.8.1.custom.min.js" type="text/javascript"></script> <script type="text/javascript" src="../../Scripts/jquery.dataTables.js"></script> <script type="text/javascript" src="../../Scripts/superfish.js"></script> <script type="text/javascript"> $(document).ready(function() { test = $('#fileTree').fileTree({script: "jqueryFileTree.aspx" }, function(file) { openFile(file); }); $("button").button(); oTable = $('#data').dataTable({ "bJQueryUI": true, "sPaginationType": "full_numbers", "bSort": true }); }); </script> and in the page, i put my div this way: <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> Documents but i'm positive that jqueryFileTree.aspx is never "called" because if i return this page in my controller, it shows the list of files/folder correctly, so it's also not a problem with my aspx connector... Also i checked, on the JS console, it gives no error and there is nothing more in the page source code i've been trying to solve this all day without success so your help is apreciated

  • Discussion - Allowing / blocking user access to pages (Client Side Only!) - Javascript / Jquery

    - by Ozaki
    TLDR Using plain HTML / Javascript (Client Side) I want to prevent viewing of certain pages. The user will have to type a username and password and depending on that they get access to different pages. Answers can NOT include server side whatsoever It does not matter if they can break it easily. There is no sensitive information etc. Also the target audience will not have access to internet OR probably know what a cookie is... At some point the user will have to type username / password.(I can define the cookie here) Currently I thought of using cookies to set a cookie for each page to say "true" / "false" but that would get messy with so many cookies. Or setting an array within a cookie for each page? I have div field "#Content" which as it looks encompasses all of my content on the page so blocking out content will be as simple as replacing it with ("sorry you don't have access") etc. For Example: $.cookie("Access","page1, page2, page3"{ expires: 1 }); I am looking for anyway to do this does not have to be with cookies. Would be nice to get a discussion of different ways this can be done. So the question is: What do YOU think would be a good way to go about doing this with client side validation?

  • What should the standard be for ReSTful URLS?

    - by gargantaun
    Since I can't find a chuffing job, I've been reading up on ReST and creating web services. The way I've interpreted it, the future is all about creating a web service for all your data before you build the web app. Which seems like a good idea. However, there seems to be a lot of contradictory thoughts on what the best scheme is for ReSTful URLs. Some people advocate simple pretty urls http://api.myapp.com/resource/1 In addition, some people like to add the API version to the url like so http://api.myapp.com/v1/resource/1 And to make things even more confusing, some people advocate adding the content-type to get requests http://api.myapp.com/v1/resource/1.xml http://api.myapp.com/v1/resource/1.json http://api.myapp.com/v1/resource/1.txt Whereas others think the content-type should be sent in the HTTP header. Soooooooo.... That's a lot of variation, which has left me unsure of what the best URL scheme is. I personally see the merits of the most comprehensive URL that includes a version number, resource locator and content-type, but I'm new to this so I could be wrong. On the other hand, you could argue that you should do "whatever works best for you". But that doesn't really fit with the ReST mentality as far as I can tell since the aim is to have a standard. And since a lot of you people will have more experience than me with ReST, I thought I'd ask for some guidance. So, with all that in mind... What should the standard be for ReSTful URLS?

  • How do I create a new project in TFS from an existing project (breaking history)?

    - by Lindsay
    My team is taking over a project from a previous team. We use a different TFS server than the original team, and we are also not interested in keeping the history of the project because we are accepting the latest version of the code as the beginning of our history with the project. Branching is not an option since we want to start our history from the current version of the code. We just want a fresh project with the existing code. I have not been able to create the new project from the old code successfully. I keep getting an error: "Source control cannot add the solution: Solution would span multiple workspaces" My process for attempting the new project creation: Create a workspace for the previous team's version of the code. Get latest version of that code into local mapped workspace directory Open the solution. Unbind all projects and solution. Close solution. Create a workspace for the new version of the code on our TFS server. Copy the unbound code on my local box to the new local workspace mapped folder. Open the solution from the new directory. "Add to source control" from the new solution. Then I get the error. I have tried removing the TFS security files out of the code directories in the unbound version and tried changing source control instead of adding to source control (but it just binds back to the original instead of letting me bind to the new). Is there any other way to do this besides recreating the solution/projects and adding back all the files and references? It doesn't seem like it should be this difficult... Any advice much appreciated!

  • Passing IDisposable objects through constructor chains

    - by Matt Enright
    I've got a small hierarchy of objects that in general gets constructed from data in a Stream, but for some particular subclasses, can be synthesized from a simpler argument list. In chaining the constructors from the subclasses, I'm running into an issue with ensuring the disposal of the synthesized stream that the base class constructor needs. Its not escaped me that the use of IDisposable objects this way is possibly just dirty pool (plz advise?) for reasons I've not considered, but, this issue aside, it seems fairly straightforward (and good encapsulation). Codes: abstract class Node { protected Node (Stream raw) { // calculate/generate some base class properties } } class FilesystemNode : Node { public FilesystemNode (FileStream fs) : base (fs) { // all good here; disposing of fs not our responsibility } } class CompositeNode : Node { public CompositeNode (IEnumerable some_stuff) : base (GenerateRaw (some_stuff)) { // rogue stream from GenerateRaw now loose in the wild! } static Stream GenerateRaw (IEnumerable some_stuff) { var content = new MemoryStream (); // molest elements of some_stuff into proper format, write to stream content.Seek (0, SeekOrigin.Begin); return content; } } I realize that not disposing of a MemoryStream is not exactly a world-stopping case of bad CLR citizenship, but it still gives me the heebie-jeebies (not to mention that I may not always be using a MemoryStream for other subtypes). It's not in scope, so I can't explicitly Dispose () it later in the constructor, and adding a using statement in GenerateRaw () is self-defeating since I need the stream returned. Is there a better way to do this? Preemptive strikes: yes, the properties calculated in the Node constructor should be part of the base class, and should not be calculated by (or accessible in) the subclasses I won't require that a stream be passed into CompositeNode (its format should be irrelevant to the caller) The previous iteration had the value calculation in the base class as a separate protected method, which I then just called at the end of each subtype constructor, moved the body of GenerateRaw () into a using statement in the body of the CompositeNode constructor. But the repetition of requiring that call for each constructor and not being able to guarantee that it be run for every subtype ever (a Node is not a Node, semantically, without these properties initialized) gave me heebie-jeebies far worse than the (potential) resource leak here does.

  • Jquery problem - cant expand the row above in a table

    - by apg1985
    Hi People, What I cant figure out is how I would toggle a row in a table using the one below it. So say I have a table with 2 rows the first contains content and the one below contains a button, when the page loads the content row is hidden and when you click the button it toggles the content row on and off. In the example the first table works but the second does not, I need the second one to work. <!DOCTYPE HTML> <html> <head> <title>Testing Horizontal Accordion</title> <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript"> $(document).ready(function() { $(".sectionhead").toggle( function() { $(this).next("tr").hide(); }, function() { $(this).next("tr").show(); } ) }); </script> </head> <body> <table> <tr class="sectionhead"><td></td></tr> <tr class="child"><td>child</td></tr> </table> <br> <table> <tr class="child"><td>child</td></tr> <tr class="sectionhead"><td></td></tr> </table> </body> </html>

  • How to make active services highly available?

    - by Jader Dias
    I know that with Network Load Balancing and Failover Clusteringwe can make passive services highly available. But what about active apps? Example: One of my apps retrieves some content from a external resource in a fixed interval. I have imagined the following scenarios: Run it in a single machine. Problem: if this instance falls, the content won't be retrieved Run it in each machine of the cluster. Problem: the content will be retrieved multiple times Have it in each machine of the cluster, but run it only in one of them. Each instance will have to check some sort of common resource to decide whether it its turn to do the task or not. When I was thinking about the solution #3 I have wondered what should be the common resource. I have thought of creating a table in the database, where we could use it to get a global lock. Is this the best solution? How does people usually do this? By the way it's a C# .NET WCF app running on Windows Server 2008

  • How can I set an absolute path for include function in php above the working directory?

    - by Baros
    I am running a script from /wp-content/themes/currenttheme/chat.php I want to include in the above php another one located in /forum/chat/index.php The index.php includes its own files I already tried `$root = $_SERVER['DOCUMENT_ROOT']; include($root."/forum/chat/index.php");` but I get this error `Warning: require(D:/My Dropbox/xampp/htdocs/lib/custom.php) [function.require]: failed to open stream: No such file or directory in D:\My Dropbox\xampp\htdocs\forum\chat\index.php on line 17 Fatal error: require() [function.require]: Failed opening required 'D:/My Dropbox/xampp/htdocs/lib/custom.php' (include_path='.;\My Dropbox\xampp\php\PEAR') in D:\My Dropbox\xampp\htdocs\forum\chat\index.php on line 17` (the index.php also includes some files, but the /forum is ommited somehow in the path) then I tried `$path = getcwd(); $myfile = "/forum/chat/index.php"; include ($path.$myfile);` and got this error: `Warning: include(D:\My Dropbox\xampp\htdocs\forum/forum/chat/index.php) [function.include]: failed to open stream: No such file or directory in D:\My Dropbox\xampp\htdocs\wp-content\themes\currenttheme\chat.php on line 24 Warning: include() [function.include]: Failed opening 'D:\My Dropbox\xampp\htdocs\forum/forum/chat/index.php' for inclusion (include_path='.;\My Dropbox\xampp\php\PEAR') in D:\My Dropbox\xampp\htdocs\wp-content\themes\currenttheme\chat.php on line 24`

  • Trying to find a PHP5 API-based embeddable CMS

    - by StrangeElement
    I've been making the rounds for a CMS that I can use as an API, in a sort of "embedded" mode. I mean by this that I don't want the CMS to do any logic or presentation. I want it to be used as an API, which I can then use within an existing site. I don't want to be tied to the architecture of the CMS. A good example of this is NC-CMS (http://www.nconsulting.ca/nc-cms/). All it needs is an include at the top, then wherever editable content is desired it's only a function call with a unique label. It's also perfect in the sense that it allows to differentiate between small strings (like titles, labels) and texts (which require a rich-text editor). It's the only CMS I found that fits this description, but it is a little too light as it does not handle site structure. I need to be able to allow my client to add pages, choosing an existing template for the layout. A minimal back-end is required. Wordpress also fits some requirements in that it handles only content editing and allows freedom for the themes by letting them call the content where and how they want it. But it is article-based and backwards, in that it embeds sites (as themes) within its structure, rather than being embeddable in sites like NC. It's funny how checking out all the CMS out there, almost all of them claim that most CMS are not self-sufficient, that they do not handle application logic, while (almost) every single on I found with only one exception do so. Many are mostly article-based blog engines, which does not fit my need. I would appreciate any CMS that fits the general description.

  • IIS site always returns 404 to WinMo emulator

    - by Derick Bailey
    I'm running Win7x64 Ultimate with Visual Studio 2008. I have a website built in ASP.NET 3.5 and hosted via IIS on my box. I can run the website perfectly fine and I can hit all of the web services that I have built in the website, using a web browser. When I pull up my Windows Mobile 6 emulator and hit the site (using my IP address) it always returns a 404 error. I have the emulator cradled w/ Device Emulator Manager and I can interact with the emulated device normally. I am also able to get out to google.com and other websites w/ the emulated device. I have also verified that the emulator is hitting my box by stopping the IIS website and seeing that the WinMo emulator cannot get any response. Then when I start the site again, I get a 404 error. When I pull up my site on my local dev box via FireFox or IE using the IP address it works perfectly fine. The worst part is this worked perfectly fine a few weeks ago, when I used it last. I don't know that I've changed anything since then - I'm just trying to use the emulator to hit my site again. Help?! Update: my http requests comign from the WinMo emulator are not getting logged in the IIS log files, while my requests from FireFox on my local box are getting logged. Not sure if that helps in figuring out the problem... Update 2: I can use the ruby Webbrick server on my local box and hit that server from my emulator just fine. is in IIS not allowing me to hit the IIS site from the emu? UPdate 3: I cradled an actual WinMo device to my box with it's networking turned off and was able to hit the IIS site just fine. that makes me think it's something set up wrong in the emulator.

  • Visual Studio macro to navigate to T4MVC link

    - by shannon
    I use T4MVC and I'm happy with it and want to keep it - it keeps down run time defects. Unfortunately, it makes it harder to navigate to views and content (a.k.a. Views and Links in T4MVC) though. Even using Resharper, I can't navigate to the referenced item: T4MVC and Resharper Navigation Can I get a hand building a macro to do this? Never having built a VS IDE macro before, I don't have a grasp on how to get at some things, like the internal results of the "Go To Definition" process, if that's even possible. If you aren't familiar with T4MVC, here's generally what the macro might do to help: Given the token: Links.Content.Scripts.jQuery_js in the file MyView.cshtml, '(F12) Go To Definition'. This behaves properly. Having arrived at the the related assignment: public readonly string jQuery_js = "~/Content/Scripts/jQuery.js"; in a file generated by T4MVC (which is very nice, thank you David, but we really don't ever need to see), capture the string assigned and close the file. Navigate in Solution Explorer to the PhysicalPath represented by the captured string. This process would also work for views/layouts/master-pages/partials, etc. If you provide a macro or link to a macro to do this, or have another solution, wonderful. Otherwise, hints on how to do step 3 simply in a VS macro would be especially appreciated and receive upvote from me. I'd post the macro back here as an answer when done. Thanks!

  • Dynamcally resizing an open Accordion

    - by alavers
    I have an Accordion and the height of its content can be dynamically resized. I would like to see the Accordion dynamically respond to the child item's height, but I'm having trouble doing this. <lt:Accordion Name="MyAccordion" SelectionMode="ZeroOrOne" HorizontalAlignment="Stretch"> <lt:AccordionItem Name="MyAccordionItem" Header="MyAccordion" IsSelected="True" HorizontalContentAlignment="Stretch" VerticalAlignment="Stretch"> <StackPanel> <Button Content="Grow" Click="Grow"/> <Button Content="Shrink" Click="Shrink"/> <TextBox Name="GrowTextBox" Text="GrowTextBox" Height="400" Background="Green" SizeChanged="GrowTextBox_SizeChanged"/> </StackPanel> </lt:AccordionItem> </lt:Accordion> private void Grow(object sender, System.Windows.RoutedEventArgs e) { GrowTextBox.Height += 100; } private void Shrink(object sender, System.Windows.RoutedEventArgs e) { GrowTextBox.Height -= 100; } private void GrowTextBox_SizeChanged(object sender, System.Windows.SizeChangedEventArgs e) { MyAccordion.UpdateLayout(); MyAccordionItem.UpdateLayout(); } Mind you, if I collapse and then re-open the accordion, it takes shape just the way I want, but I'd like this resizing to occur immediately when the child resizes. I feebly attempted to fix this by adding a SizeChanged event handler that calls UpdateLayout() on the Accordion and AccordionItem, but this doesn't have any visual effect. I can't figure out where proper resizing takes place inside the Accordion control. Does anyone have an idea?

  • How to choose light version of database system

    - by adopilot
    I am starting one POS (Point of sale) project. Targeting system is going to be written in C# .NET 2 WinForms and as main database server We are going to use MS-SQL Server. As we have a lot of POS devices in chain for one store I will love to have backend local data base system on each POS device. Scenario are following: When main server goes down!! POS application should continue working "off-line" with local database, until connection to main server come up again. Now I am in dilemma which local database is going to be most adoptable for me. Here is some notes for helping me point me in right direction: To be Light "My POS devices art usually old and suffering with performances" To be Free "I have a lot of devices and I do not wont additional cost beside main SQL serer" One day Ill love to try all that port on Mono and Linux OS. Here is what I've researched so far: Simple XML "Light but I am afraid of performance, My main table of items is average of 10K records" SQL-Express "I am afraid that my POS devices is poor with hardware for SQLExpress, and also hard to install on each device and configure" Less known Advantage Database Server have free distribution of offline ADT system. DBF with extended Library,"Respect for good old DBFs but that era is behind Me with clipper and DBFs" MS Access Sqlite "Mostly like for now, but I am afraid how it is going to pair with MS SQL do they have same Data types". I know that in this SO is a lot of subjective data, but at least can someone recommended some others lite database system, or things that I shod most take attention before I choice database.
