• javascript not working on localhost

  - by Adam McMahon

  Ok so I'm lost here, frustrated and pulling my hair and out. Plus probably about to be fired or take a pay cut. I moved Files from a development server to my local machine. The files are consistent (used diff tool), all the dependencies are there. It works for the most part. The problem is that the some of the javascript (not all) is just not working. We're using jquery and a lot of plugins for it. I've checked with the web developer plugin in firefox and all the js files are loading. I cleared the cache in both firefox and chrome multiple times to no avail. The development server is a windows server running wamp. My local machine is running ubuntu. Somebody tell me what I missed.

• IF/ELSE makes stored procedure not return a result set

  - by Brendan Long

  I have a stored procedure that needs to return something from one of two databases: IF @x = 1 SELECT @y FROM Table_A ELSE IF @x = 2 SELECT @y FROM Table_B Either SELECT alone will return what I want, but adding the IF/ELSE makes it stop returning anything. I tried: IF @x = 1 RETURN SELECT @y FROM Table_A ELSE IF @x = 2 RETURN SELECT @y FROM Table_B But that causes a syntax error. The two options I see are both horrible: Do a UNION and make sure that only one side has any results: SELECT @y FROM Table_A WHERE @x = 1 UNION SELECT @y FROM Table_B WHERE @x = 2 Create a temporary table to store one row in, and create and delete it every time I run this procedure (lots). Neither solution is elegant, and I assume they would both be horrible for performance (unless MS SQL is smart enough not to search the tables when the WHERE class is always false). Is there anything else I can do? Is option 1 not as bad as I think?

• WPF DataGrid content does not scroll

  - by muffd

  After searching for a fix to this issue in the previous answers I've decided to post my example. I have the following situation: my datagrid is placed inside a Grid row that is itself placed inside a UserControl.The UserControls does not have a fixed height, as I want the control to resize together with the window. The datagrid is bound to a datasource. Needless to say that the Datagrid itself and its container(the Grid) do not have set a fixed height. My question is: how do I make the vertical scrollbar of the DataGrid to appear?

• Postgresql error: could not open segment 1 of relation base/20983/2416

  - by kokonut

  I'm running a Postgresql query and getting the following error: ActiveRecord::StatementInvalid (PGError: ERROR: could not open segment 1 of relation base/20983/24161 (target block 5046584): No such file or directory The query is of the format 'SELECT "locations".* FROM "locations" WHERE ("locations"."id" IN (115990, 78330, 77891, 78248, ...)' with about 600 ids in the IN clause - not an optimal query I know but it's what I have to work with for the moment! The server is running PostgreSQL 8.4.6 on x86_64-pc-linux-gnu, compiled by GCC gcc-4.4.real (Ubuntu 4.4.1-4ubuntu9) 4.4.1, 64-bit. Postgis 1.5 is also installed, and the locations table contains a geometry column. Anyone have any idea what could be causing the error? Thanks!

• Images not displaying if using file:///c:/

  - by Ben

  I am using jQuery and would like to display the images from my PC, rather than hosting them. I have the following: /* works fine: */ .ui-widget-header .ui-icon { background-image: url(images/ui-icons_2e83ff_256x240.png); } /* does not work: */ .ui-widget-header .ui-icon { background-image: url(file:///C:/ui-icons_2e83ff_256x240.png); } When I put file:///C:/ui-icons_2e83ff_256x240.png in a browser, it displays the actual image beautifully. Both locations are valid image locations. Could this not working be to do with the image being a sprite? Does anyone have any ideas on this one? Many thanks.

• Form action with #hashtag not working in internet explorer

  - by Stephane

  I am using jquery-ui tabs and I've set it up to select the correct tab depending on the #hash from the requested URL. I have a form which performs a search, and each tab present the result from different providers. so if the form is submitting to the action "/myAction#tab1", when the results load, the corresponding tab gets selected. This works perfectly in every browser except for IE. When my form is submitted, it loses somehow the #hash which describes which tab to select. Is that yet another a bug from IE, or am I doing something wrong? I could not find much information about this, but I can hardly believe that this is not a common problem.

• difference in using virtual and not using virtual

  - by numerical25

  In C++, whether you choose to use virtual or not, you can still override the base class function. The following compiles just fine... class Enemy { public: void SelectAnimation(); void RunAI(); void Interact() { cout<<"Hi I am a regular Enemy"; } private: int m_iHitPoints; }; class Boss : public Enemy { public: void Interact() { cout<<"Hi I am a evil Boss"; } }; So my question is what is the difference in using or not using the virtual function. And what is the disadvantage.

• modrewrite to another server if file/image is not found

  - by Traveling_Monk

  Hi I am working on a locally served copy of a remote site and I don't want to have to download all the images rtelated to the site so I thought i could come up with a mod_rewrite rule for to grab images from the remote server if the are not found this is the code that i have <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{REQUEST_FILENAME} -f [NC] RewriteRule ^/(.*\.(png|gif|jpg|jpeg)) https://www.exmple.com/$1 [NC,P,L] </IfModule> The page is still giving me 404's for images that are on the remote server, so this rule is not working. I do know that the htaccess is being processed because rules later in the IfModule mod_rewrite.c block are being used. (i simplified my code sample but this is the first rule in the IfModule mod_rewrite.c block)

• Could not retrieve data from URL

  - by user1655065

  I have a lot of websites which are using the same CMS, and they are hosted in 3 seperated servers, only one of this servers has a problem with retrieving the title, description, and the image of any url, and in the FaceBook debugger I get this error: Could not retrieve data from URL. From previous questions, I read that the reason may be an HTML error, but as I said before on other servers there is no problem using the same CMS. You can try putting this URL for example in the debugger: http://www.shaharah.net/2010/news-10054.htm Also, other websites on the same server which are using another CMS, or is just HTML pages are also not retrieved. Thanks. Best regards, Aws Aleryani

• DOM Level 3 CustomEvents not bubbling on WebKit

  - by Edu Felipe

  I'm observing CustomEvents not bubbling, even though I set bubbling to true. The code below: var evt = document.createEvent("CustomEvent") evt.initCustomEvent("mycustomevent", true, false) var someh1 = document.getElementById("someh1") someh1.addEventListener("mycustomevent", function(){ alert("OMG!"); }) document.getElementsByTagName("body")[0].dispatchEvent(evt) With the HTML below: <html> <head></head> <body> <h1 id="someh1">content!</h1> </body> </html> Never shows the alert, demonstrating that the event is not bubbling down. Am I doing something wrong? Please note that if I do a getElementById("someh1") and run the dispatchEvent on it, the alert is displayed. Thanks!
