  • WordPress page is listed in "Posts" but appears on site as a "Page", What gives?

    - by Scott B
    I've seen this on a few sites now and its puzzling me. The page will be listed under the "Edit Posts" listing, however, when I click on "View Page" to see the live post, its being served out as a "Page". I can tell this by viewing the source and the body tag is... <body class="page page-id-37 logged-in"> If its were actually a post, the body tag should be <body class="single postid-63 logged-in"> I've seen a "post to page" and a "page to post" plugin that will convert between pages and posts, however, this site has NO plugins other than the wordpress defaults (akismet and hello dolly). I'm stumped.

  • Fix common library functions, or abandon then?

    - by Ian Boyd
    Imagine i have a function with a bug in it: Boolean MakeLocation(String City, String State) { //Given "Springfield", "MO" //return "Springfield, MO" return City+", "+State; } So the call: MakeLocation("Springfield", "MO"); would return "Springfield, MO" Now there's a slight problem, what if the user called: MakeLocation("Springfield, MO", "OH"); The called it wrong, obviously. But the function would return "Springfield, MO, OH". The system was functioning like this for many years, until i noticed the function being used wrong, and i corrected it. And i also updated the original function to catch such an obvious mistake - in case it's happening elsewhere: Boolean MakeLocation(String City, String State) { //Given "Springfield", "MO" //return "Springfield, MO" if (City.Contains, ",") throw new EMakeLocationException("City name contains a comma. You probably didn't mean that"); return City+", "+State; } And testing showed the problem fixed. Except we missed an edge case, and the customer found it. So now the moral dillema. Do you ever add new sanity checks, safety checks, assertions to exising code? Or do you call the old function abandoned, and have a new one: Boolean MakeLocation(String City, String State) { //Given "Springfield", "MO" //return "Springfield, MO" return City+", "+State; } Boolean MakeLocation2(String City, String State) { //Given "Springfield", "MO" //return "Springfield, MO" if (City.Contains, ",") throw new EMakeLocationException("City name contains a comma. You probably didn't mean that"); return City+", "+State; } The same can apply for anything: Question FetchQuestion(Int id) { if (id == 0) throw new EFetchQuestionException("No question ID specified"); ... } Do you risk breaking existing code, at the expense of existing code being wrong?

  • Render an asp.net control from a text string

    - by madness
    Hi All, I'm not sure if it is possible to render an asp.net control from a string. The string contains fragments of html code and I've tried rendering that string to a div tag with runat="server" set, asp panel contain, asp lalbel control and asp literal control. All of them doesn't render the asp control in that text to an actual control, it just come up as a string. I've tried adding <% % around them and it appears it doesn't like it. Thanks in advance.

  • Losing DateTimeOffset precision when using C#

    - by Darvis Lombardo
    I have a SQL Server table with a CreatedDate field of type DateTimeOffset(2). A sample value which is in the table is 2010-03-01 15:18:58.57 -05:00 As an example, from within C# I retrieve this value like so: var cmd = new SqlCommand("SELECT CreatedDate FROM Entities WHERE EntityID = 2", cn); var da = new SqlDataAdapter(cmd); DataTable dt =new DataTable(); da.Fill(dt); And I look at the value: MessageBox.Show(dt.Rows[0][0].ToString()); The result is 2010-03-01 15:18:58 -05:00, which is missing the .57 that is stored in the database. If I look at dt.Rows[0][0] in the Watch window, I also do not see the .57, so it appears it has been truncated. Can someone shed some light on this? I need to use the date to match up with other records in the database and the .57 is needed. Thanks! Darvis

  • LINQ To SQL ignore unique constraint exception and continue

    - by Martin
    I have a single table in a database called Users Users ------ ID (PK, Identity) Username (Unique Index) I have setup a unique index on the Username table to prevent duplicates. I am then enumerating through a collection and creating a new user in the database for each item. What I want to do is just insert a new user and ignore the exception if the unique key constraint is violated (as it's clearly a duplicate record in that case). This is to avoid having to craft where not exists kind of queries. First off, is this going to be any more efficient or should my insert code be checking for duplicates instead? I'm drawn more to the database having that logic as this prevents any other type of client from inserting duplicate data. My other issue is related to LINQ To SQL. I have the following code: public class TestRepo { DatabaseDataContext database = new DatabaseDataContext(); public void Add(string username) { database.Users.InsertOnSubmit(new User() { Username = username }); } public void Save() { database.SubmitChanges(); } } And then I iterate over a collection and insert new users, ignoring any exceptions: TestRepo repo = new TestRepo(); foreach (var name in new string[] { "Tim", "Bob", "John" }) { try { repo.Add(name); repo.Save(); } catch { } } The first time this is run, great I have three users in the table. If I remove the second one and run this code again, nothing is inserted. I expected the first insert to fail with the exception, the second to succeed (as I just removed that item from the DB) and the third to then fail. What seems to be happening is that once the SqlException is thrown (even though the loop continues to iterate) all of the next inserts fail - even when there isn't a row in the table that would cause a unique violation. Can anyone explain this? P.S. The only workaround I could find was to instantiate the repo each time before the insert, then it worked exactly as excepted - indicating that it's something to do with the LINQ To SQL DataContext. Thanks.

  • What are all the differences between pipes and message queues?

    - by aks
    What are all the differences between pipes and message queues? Please explain both from vxworks & unix perspectives. I think pipes are unidirectional but message queues aren't. But don't pipes internally use message queues, then how come pipes are unidirectional but message queues are not? What are the other differences you can think of (from design or usage or other perspectives)?

  • In WebBrowser control get Silverlight Canvas

    - by darren
    I have a webbrowser control that loads an html page which contains a silverlight object. I want to use the webbrowser control to get the silverlight canvas so that I can pass it to a WriteableBitmap() object. The silverlight is being loaded into a div called SilverlightHostControl and I am trying to get it like this in C#: object element = webBrowser.Document.GetElementById("SilverlightControlHost"); This returns a {System.Windows.Forms.HtmlElement} which contains the silverlight object but I don't know how to get the Silverlight object so I can use it the WriteableBitmap() object.

  • Modifications in default document (ASP.NET+IIS7) won't take effect

    - by Wilson
    We have a website developed by ASP.NET+IIS7 and its default document is default.aspx. It works fine. But when we tried to switch the default to index.html, weird things happened. We have modified web.config as follows: <defaultDocument> <files> <clear /> <add value="index.html" /> </files> </defaultDocument> and we have clear everything under C:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files``, and restart the worker process. We even changed the name of Default.aspx to dddd.aspx. But everything stays the same when accessing with http://localhost/<MyAppName>/! And when we tried to access with http://localhost/<MyAppName>/index.html, it works fine. Any suggestions would be highly appreciated.

  • SVN client too old after I used sshfs

    - by johnlai2004
    I have a svn checked out web application on a shared hosting linux server. The linux server has an svn client that I can access via ssh. From my localhost, I did the following > sshfs [email protected]:webappdir/ /media/webapp > cd /media/webapp > svn update svn: Working copy '.' locked svn: run 'svn cleanup' to remove locks (type 'svn help cleanup' for details) > svn clean up It's been 15 minutes and the svn clean up still isn't finished. I think it may have froze. So then I did the following: > ssh [email protected] > cd webappdir > svn update svn: This client is too old to work with working copy '.'; please get a newer Subversion client So now I can't update my webappdir because my /media/webapp is stuck on svn clean up, and my shared hosting server's svn client is out of date. I don't have privileges to install a new svn client on the shared hosting server. How do I get my svn update to work?

  • HP ProCurve Port Mode Configuration Question

    - by SvrGuy
    We have a ProCurve Switch 2810-48G (J9022A). We need to disable auto negotiation on two ports and manually configure them to be full duplex gige ports. From the web GUI, Configuration Tab, Port Configuration sub tab, I am only presented with the option to configure the port as Auto - 1000. I take this to mean, auto negotiate duplex, manually configure the speed to be gige. How do I manually configure the port such that it is manually configured to use full duplex, 1000 mbs?

  • windows server 2008 web edition cant change permissions

    - by minus4
    hi there, Im used to using windows server 2003 but decided to get a Vista web edition for IIS7 and to run our MVC applications on. I have installed copSSH that i use for SFTP, and when i upload my files i am unable to change persmissions or take ownership or anything when logged in as an administrator. when i try to go to permissions i get: The permissions on uploads are incorrectly ordered, which may cause some entries to be ineffective. and all permissions are the grayed out. i have tried to use icacls to reset ownership and also tried to give myself full control through icacls however all attempts are met with a access is denied message and failed processing 669 files. all i wish to do is set up write and delete permissions on an upload folder for a CMS systems admin area, but i am a week into looking into this and i am still no wiser. Please could someone give some sound advice so i can get this running smooth thanks p.s i have added the copSSH notes as i think that when i SFTP the files to the server, this may somehow have some involvement in messing up permissions

  • TF2 with Parallels on a MacBook Pro

    - by Eric Koslow
    I am trying to get TF2 to run under Parallels on my 15'' MacBook Pro, but it is ultimatly failing. To get any decent frame rate I have to put all the setting to low, but even then I get weird graphical "gliches" when I play. Controlls are unresponsive and very laggy as well. I have increased the video memory to 256mb, but that doesn't seem to have helped. What else should I do to make the game playable?

  • How to get rid of resume information on ubuntu 9.10 ("karmic")

    - by Glen S. Dalton
    I am on an old laptop with Ubuntu 9.10 installed. I once tried to not shutdown but go into one of the resume states. On the next power on, resume did not work, but there was an error message during boot asking me for the resume image (which I do not have or know of) and when I press enter the normal boot happens. But this error pops up on every boot now. How can I get back the behaviour from before? Why does the boot process guess there would be a resume image and can I delete this information? I would like to post here the error messages from the boot proces, but they are not in /var/log/syslog, where else can they be?

  • Easiest/Best Way to Learn the x86 Instruction Set?

    - by mudge
    I would like to learn the x86 Instruction Set Architecture. I don't meaning learning an assembly for x86. I want to understand the machine code baby. The reason is that I would like to write an assembler for x86. Then I want to write a compiler that compiles to that assembly. I know that there are the Intel manuals and AMD manuals that cover the x86 instruction set. But those are very large and dense. I'm wondering if there is a more approachable (possibly tutorial) approach to learning the x86 instruction set architecture.

  • Div behind another div problem.

    - by Kyle Sevenoaks
    Here is a (big) example of the massive problem I am having, when this page is live at euroworker.no/order, it is dynamically generated, I have supplied a static version for people to mess with. All I need is where it says "Endre Valg" to push the div wrapper under it down.. Sounds easy huh? I have tried many many things, I hope that some discussion and even trial and error can help us here. Sorry for the huge amount of code and stuff but this has taken me all day and I am out of ideas. Thanks.

  • Issue with my regular expression?

    - by Rubans
    I'm trying to locate the number matches in a relative path for directory up references("..\"). So I have the following pattern : "(..\)" which works as expected for the path "....\a\b" where it will give me 2 successfull groups ("..\") but when I try the path "..\a\b" it will also return 2 when it should be 1. I tried this in a reg ex tool such Expresso and it seems to work as expected in there but not in in .net, any ideas?

  • Flash AS3: (VideoEvent.COMPLETE, completePlay) - listener is triggered before video is completed

    - by Tevi
    Hello, I have a flash video using the standard FLV Playback component that comes with Flash. I'm using ActionScript 3 to modify the appearance and set up an event listener. I've set it up to go to a new URL using "externalInterface" when the video completes play. The URL is set in a variable using SWFObject. On only a few instances (3 people out of 50 - tested using Amazon Turk), people reported being taken directly to the new url, before the video even started playing. It's difficult to repeat the issue, but it did happen to me once. It doesn't have anything to do with cache, since it has been reported on people going to the url for the first time. Here's the url to the video: http://www.partstown.com/is-bin/INTERSHOP.enfinity/WFS/Reedy-PartsTown-Site/en_US/-/USD/ViewStaticPage-UnFramed?page=tourthetown Here's the code: import flash.external.*; import fl.video.*; var myVideo:FLVPlayback = new FLVPlayback(); var theUrl:String = this.loaderInfo.parameters.urlName; var theScript:String = this.loaderInfo.parameters.scriptName; myVideo.source = this.loaderInfo.parameters.videoPath;//"partstown.flv"; myVideo.skin = this.loaderInfo.parameters.skinPath;//"SkinUnderPlayStopSeekMuteVol.swf" myVideo.skinBackgroundColor = 0xAEBEFB; myVideo.skinBackgroundAlpha = 0.5; myVideo.width = 939; myVideo.height = 660; myVideo.addEventListener(VideoEvent.COMPLETE, completePlay); function completePlay(e:VideoEvent):void { myVideo.alpha=0.2; ExternalInterface.call(theScript); } addChild(myVideo); Why would the listener be triggered before the event complete? How can I fix it? Thanks!

  • Question about the code of the backend of symfony

  • How do I controll clipping with non-opaque graphics-item's in Qt?

    - by JJacobsson
    I have a bunch of QGraphicsSvgItem's in a QGraphicsScene that are drawn connected by QGraphicsLineItem's. This show's a graph of a tree-structure. What I want to do is provide a feature where everything but a selected sub-tree becomes transparent. A kind of "highlight this sub-tree" feature. That part was easy, but the results are ugly because now the lines can be seen through the semi-transparent svg's. I am looking for some way to still clip other QGraphicsItem's in the scene to the svg item's, giving the effect that the svg's are semi-transparent windows to the background. I know this code does not use svg's but I figure you can replace that yourself if you are so inclined. int main(int argc, char *argv[]) { QApplication app(argc, argv); QGraphicsScene scene; for( int i = 0; i < 10; ++i ) { QGraphicsLineItem* line = new QGraphicsLineItem; line->setLine( i * 25.0 + 1.0, 0, i * 25.0 + 23.0, 0 ); scene.addItem( line ); } for( int i = 0; i < 11; ++i ) { QGraphicsEllipseItem* ellipse = new QGraphicsEllipseItem; ellipse->setRect( (i * 25.0) - 9.0, -9.0, 18.0, 18.0f ); ellipse->setBrush( QBrush( Qt::green, Qt::SolidPattern ) ); ellipse->setOpacity( 0.5 ); scene.addItem( ellipse ); } QGraphicsView view( &scene ); view.show(); return app.exec(); } I would like the line's to not be seen behind the circle's. I have tried fiddling with the depth-buffer and the stencil buffer using opengl rendering to no avail. How do I get the QGraphicsSvgItem's (or QGraphicsEllipseItem's in the example code) to still clip the lines even though they are semi-transparent?
