    Is there a way to fire up Scriptaculous's Autocomplete to search with the default word from the inputfield when the page is loaded?

  • jQuery Sparklines: $.getJSON data can't be read

    - by Bob Jansen
    I'm trying to generate a pie graph with Sparklines but I'm running into some trouble. I can't seem to figure out what I'm doing wrong, but I feel it is a silly mistake. I'm using the following code to generate a sparkline chart in the div #traffic_bos_ss: //Display Visitor Screen Size Stats $.getJSON('models/ucp/traffic/traffic_display_bos.php', { type: 'ss', server: server, api: api, ip: ip, }, function(data) { var values = data.views; //alert(values); $('#traffic_bos_ss').sparkline(values, { type: "pie", height: "100%", tooltipFormat: 'data.screen - {{value}}', }); }); The JSON string fetched: {"screen":"1220x1080, 1620x1080, 1920x1080","views":"[2, 2, 61]"} For some reason Sparklines does not process the variable values. When I alert the variable it outputs "[2, 2, 61]". Now the jQuery code does work when I replace the snippet: var values = data.views; with var values = [2, 2, 61]; What am I doing wrong?

  • How can I display characters in a map by mapfile?

    - by sirius
    Hello. I'm trying to show a map using postGIS+Mapserver.And I've displayed a PNG picture in my WEB. However, I want to show some charactors in the map, just like this: this is the example from Mapserver Now I'm using database(postgreSQL), but not a shape file. How can I add the charactors then? Here is a part of my mapfile: LAYER CONNECTIONTYPE postgis NAME "state" //Connect to a remote spatial database CONNECTION "user=postgres dbname=*** host=*** password=***" PROCESSING "CLOSE_CONNECTION=DEFER" DATA "the_geom from province" STATUS ON TYPE POLYGON CLASS STYLE COLOR 122 122 122 OUTLINECOLOR 0 0 0 END LABEL COLOR 132 31 31 SHADOWCOLOR 218 218 218 SHADOWSIZE 2 2 TYPE TURETYPE FONT arial-bold SIZE 12 ANTIALIAS TRUE POSITION CL PARTIALS FALSE MINDISTANCE 300 BUFFER 4 END END Some said adding a "TEXT ([*])" in "LABEL", but I don't know howto?

  • ASP.NET - Themes and Relative Referencing

    - by user70192
    Hello, I have an ASP.NET application that uses themes. Let's pretend I have a theme named "MySkin". I have a page that is in a sub-directory of my application. When I reference a page that uses "MySkin", I noticed that ASP.NET renders a link element that walks up to the root of the site and then down into the App_Themes directory. Here is an example link element I found in a rendered ASP.NET page: <link href="../../App_Themes/MySkin/theme.css" type="text/css" rel="stylesheet" /> Is there a reason that the rendered link element does not use the following instead: <link href="/App_Themes/MySkin/theme.css" type="text/css" rel="stylesheet" /> Is this a browser compatibility issue or is there another reason? The reason I am asking is because I am rendering my ASP.NET page using Server.Execute and storing the result in a different directory. Because of this, I would prefer to use the second way to reference my theme's css. Thank you!

  • JQuery Menu plugins under ASP.NET MVC seem to only work in Chrome, but not in IE & FireFox

    - by Antony
    Recently, I was trying to prototype some jQuery-based menu into ASP.NET MVC. Just to name two examples here: plugins.jquery.com/project/columnview www.filamentgroup.com/lab/jquery_ipod_style_and_flyout_menus/ Their demo page looks great, but when I integrate their sample code into MVC, the script no longer works in IE and FireFox, but it seems to work just fine under Google Chrome. Can someone kindly enough to point out what I missed? I will be honest here. I am still new to JavaScript, so it is still a learning phase to me, so any help is highly appreciated. I have placed a copy of my VS2010 solution zip file @ http://db.tt/0UNDkN Here is what I did. In the Site.Master, I have something like <body> <div class="page">{truncated...}</div> <script src="http://code.jquery.com/jquery-1.4.2.min.js" type="text/javascript" charset="utf-8"></script> <asp:ContentPlaceHolder ID="ScriptContent" runat="server" /> </body> And inside View file, I have the following <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <div id="original"> {some demo block, copied from javascript demo} </div> </asp:Content> <asp:Content ID="Content3" ContentPlaceHolderID="ScriptContent" runat="server"> <script type="text/javascript" src="<%= Url.Content("~/Scripts/jquery.columnview.js") %>" /> <script type="text/javascript"> $(document).ready(function () { $('#original').columnview(); }); </script> </asp:Content> Compiled the code and ran it under IE. Ideally, it should work like the demo in www.christianyates.com/blog/jquery/finder-column-view-hierarchical-lists-jquery, but in reality, it only displays unordered list in plain view. (If you download the solution file and run it, you should be able to repro this as well). Next, tried with FireFox, not working either, same result as IE. Finally, when I try it under Google Chrome 4.1 (lastest version), and the script displays just fine. Really puzzling here :-/ Thank you for reading :D

  • How to import a module from a directory?

    - by Roman
    On my system I have two versions of Python (to call them I type python and python2 in the command line). When I use the first version of Python, I cannot import sklearn module but I can do it in the second version of Python. I would like to use the first version of python (because other modules are available there) and, at the same time, I would like to be able to import sklearn from this version of Python. My solution was to use: import sys sys.path.append('location_of_the_sklearn_module') To find the location of the sklearn module I started a python session (using the second version of python, in which sklearn works). The I type: import sklearn sklearn.__file__ As a result I got: /home/name/my_name/numpy/local/lib/python2.7/site-packages/sklearn/__init__.pyc In the session of the first version of Python I tried: import sys sys.path.append('/home/name/my_name/numpy/local/lib/python2.7/site-packages/sklearn') import sklearn Unfortunately it did not work. As a result I got: ImportError: No module named sklearn Does anybody know what I am doing wrong and if it is possible to reach the goal in the way I try?

  • Haskell FlatMap

    - by mvid
    I am a beginner interested in Haskell, and I have been trying to implement the flatmap (=) on my own to better understand it. Currently I have flatmap :: (t -> a) -> [t] -> [a] flatmap _ [] = [] flatmap f (x:xs) = f x : flatmap f xs which implements the "map" part but not the "flat". Most of the modifications I make result in the disheartening and fairly informationless Occurs check: cannot construct the infinite type: a = [a] When generalising the type(s) for `flatmap' error. What am I missing?

  • LinqToSql: insert instead of update

    - by Christina Mayers
    I am stuck with this problems for a long time now. Everything I try to do is insert a row in my DB if it's new information - if not update the existing one. I've updated many entities in my life before - but what's wrong with this code is beyond me (probably something pretty basic) I guess I can't see the wood for the trees... private Models.databaseDataContext db = new Models.databaseDataContext(); internal void StoreInformations(IEnumerable<EntityType> iEnumerable) { foreach (EntityType item in iEnumerable) { EntityType type = db.EntityType.Where(t => t.Room == iEnumerable.Room).FirstOrDefault(); if (type == null) { db.EntityType.InsertOnSubmit(item); } else { cur.Date = item.Date; cur.LastUpdate = DateTime.Now(); cur.End = item.End; } } } internal void Save() { db.SubmitChanges(); }

  • What is your favourite JavaScript reference manual?

    - by daniel.sedlacek
    Hi, I come from strong typed unambiguous OOP background and I struggle to find JavaScript reference manual that would fit my needs. The ideal one should be: compendious and handy, I'm not looking for ECMA standart reference. type specific, even if JS is not strong typed function arguments and returns have a type. browser specific, no matter the standards every browser is different and this ambiguity is killing me. examples, they are always handy. off line, this would be fine but it's not a condition. What is your favourite one? Help me, Obi-Wan Kenobi; you're my only hope!

  • jboss connection pooling

Because of that existing Prepared Statements are removed from the pool of cached Prepared Statements. How to overcome this issue? I have to use idle-timeout-minutes because MySQL server closes the connection after 8h

  • Openlayers - LayerRedraw() / Feature rotation

    - by Ozaki
    TLDR: I have an Openlayers map with a layer called 'track' I want to remove track and add track back in. I have an image 'imageFeature' on a layer that rotates on load to the direction being set. I want it to update this rotation that is set in 'styleMap' on a layer called 'tracking'. I set the var 'stylemap' to apply the external image & rotation. The 'imageFeature' is added to the layer at the coords specified. 'imageFeature' is removed. 'imageFeature' is added again in its new location. Rotation is not applied.. As the 'styleMap' applies to the layer I think that I have to remove the layer and add it again rather than just the 'imageFeature' Layer: var tracking = new OpenLayers.Layer.GML("Tracking", "coordinates.json", { format: OpenLayers.Format.GeoJSON, styleMap: styleMap }); styleMap: var styleMap = new OpenLayers.StyleMap({ fillOpacity: 1, pointRadius: 10, rotation: heading, }); Now wrapped in a timed function the imageFeature: map.layers[3].addFeatures(new OpenLayers.Feature.Vector( new OpenLayers.Geometry.Point(longitude, latitude), {rotation: heading, type: parseInt(Math.random() * 3)} )); Type refers to a lookup of 1 of 3 images.: styleMap.addUniqueValueRules("default", "type", lookup); var lookup = { 0: {externalGraphic: "Image1.png", rotation: heading}, 1: {externalGraphic: "Image2.png", rotation: heading}, 2: {externalGraphic: "Image3.png", rotation: heading} } I have tried the 'redraw()' function: but it returns "tracking is undefined" or "map.layers[2]" is undefined. tracking.redraw(true); map.layers[2].redraw(true); Heading is a variable: from a JSON feed. var heading = 13.542; But so far can't get anything to work it will only rotate the image onload. The image will move in coordinates as it should though. So what am I doing wrong with the redraw function or how can I get this image to rotate live? Thanks in advance -Ozaki Add: I managed to get map.layers[2].redraw(true); to sucessfully redraw layer 2. But it still does not update the rotation. I am thinking because the stylemap is updating. But it runs through the style map every n sec, but no updates to rotation and the variable for heading is updating correctly if i put a watch on it in firebug.

  • Providing updating suggestions list with javascript, php and ajax

    I'm trying to modify this example on making a live updating list to integrate it with my API.

  • Which PHP session settings are incorrect here?

    - by Greg McNulty
    I see the savepath has no value but does it default to something? Are the other values OK? I have access to the server and PHP files but how and what do I change? The specific issue - On page 1: session_start(); $_SESSION['uType']=$row['usertype']; //save user type to session print_r($_SESSION); //Prints the user type successfully On page 2: session_start(); print_r($_SESSION); //BLANK?? Observed: Page 1 displays the session data. However, there are NO cookies created anywhere on the browser? Page 1 does a require to display page 2. Page 2 does not contain the session data. Using FireFox as the target browser (looking at cookies with web developer add-in) How do I get the session to work across all pages? Thank You and yes I am a newbie at this.

  • Is do-notation specific to "base:GHC.Base.Monad"?

    - by yairchu
    The idea that the standard Monad class is flawed and that it should actually extend Functor or Pointed is floating around. I'm not necessarily claiming that it is the right thing to do, but suppose that one was trying to do it: import Prelude hiding (Monad(..)) class Functor m => Monad m where return :: a -> m a join :: m (m a) -> m a join = (>>= id) (>>=) :: m a -> (a -> m b) -> m b a >>= t = join (fmap t a) (>>) :: m a -> m b -> m b a >> b = a >>= const b So far so good, but then when trying to use do-notation: whileM :: Monad m => m Bool -> m () whileM iteration = do done <- iteration if done then return () else whileM iteration The compiler complains: Could not deduce (base:GHC.Base.Monad m) from the context (Monad m) Question: Does do-notation work only for base:GHC.Base.Monad? Is there a way to make it work with an alternative Monad class? Extra context: What I really want to do is replace base:Control.Arrow.Arrow with a "generalized" Arrow class: {-# LANGUAGE TypeFamilies #-} class Category a => Arrow a where type Pair a :: * -> * -> * arr :: (b -> c) -> a b c first :: a b c -> a (Pair a b d) (Pair a c d) second :: a b c -> a (Pair a d b) (Pair a d c) (***) :: a b c -> a b' c' -> a (Pair a b b') (Pair a c c') (&&&) :: a b c -> a b c' -> a b (Pair a c c') And then use the Arrow's proc-notation with my Arrow class, but that fails like in the example above of do-notation and Monad. I'll use mostly Either as my pair type constructor and not the (,) type constructor as with the current Arrow class. This might allow to make the code of my toy RTS game (cabal install DefendTheKind) much prettier.

  • How to kill tasks in Windows 7 when even Task Manager won't open or respond?

    - by endolith
    Occasionally one of my computers will get so bogged down that everything locks up, Ctrl+Alt+Del doesn't work, Task Manager won't open, or they work, but are opening so slowly that it will take hours or days to shut down other processes and regain control of the computer, etc. Is there a way to, for instance, force Task Manager to be highest priority so it always opens immediately with Ctrl+Shift+Esc even when some other process/driver is hogging the CPU? Is there some other program that can run in the background and open immediately like this? This question isn't about fixing "underlying problems". No matter how much memory you have, it's still possible for a rogue process to eat it all up and lock up the computer in page fault thrashing, hog the CPU, etc. This question is about how to take back control of the computer when that happens. Basically when these kind of lock-ups happen, I want to open some kind of task manager that pauses every other process and allows me to kill one of them, and then let everything resume so I can save my work, etc. Otherwise my only option is to hold down the power button. Antifreeze is supposed to do exactly what i want, pausing all other applications and starting a task manager to kill the offender, but in my testing, it actually does neither.

  • Problem evaluating NULL in an IIF statement (Access)

    - by Mohgeroth
    Item in the recordset rstImportData("Flat Size") is = Null With that, given the following statement: IIF(IsNull(rstImportData("Flat Size")), Null, cstr(rstImportData("Flat Size"))) Result: Throws error 94: Invalid use of Null If I change the statement by removing the type conversion upon a false comparison: IIF(IsNull(rstImportData("Flat Size")), Null, 0) Result: Null It returns Null as it should have the first time. It appears that I cannot do a type conversion in an IIF if the value passed in should ever be null even if it passes an IIF test, it still attempts to evaluate it at both the true and false answer. The only reason I'm using IIF like this is because I have a 25 line comparison to compare data from an Import against a matching record in a database to see if I need to append the prior to history. Any thoughts? The way data is imported there will be null dates and where the spreadsheet import is in a string format I must convert either side to the other to compare the values properly but if either side is null this exception occurs :(

  • How to access a field's value via reflection (Scala 2.8)

I tried things like field.get(foo), but that just returns an java.lang.Object but no String. Basically I need the correct type, because I want to invoke a method on it (e. g. toCharArray). What is the suggested way to do that?

    - by JGr
    How can i create a Action method to use as a argument to the following function? public void When(Action<T> action) { if (internalValue != null) action(internalValue); } I have the MethodInfo on the method, and the parameter type like so: var methods = value.GetType().GetMethods(); MethodInfo mInfo = methods.First(method => method.Name == "When"); Type parameterType = (mInfo.GetParameters()[0]).ParameterType; But after that i have no idea how to make the actual Action method to pass as argument, i also do not know how to define the Action method body.

  • Emails sent using Flex app are delayed

    - by user363825
    I'm currently building an application in Flex that utilizes SMTP Mailer to automatically send out emails to the user when a particular condition is satisfied. The application checks this condition every 30 seconds. The condition is satisfied based on new records being returned from a database table. The problem is as follows: When the condition is first satisfied, the email is delivered to the user with no issues. The second time the condition is satisfied, the email is not delivered. In the smtp logs, the delivery attempt appears to get hung up on the following line: 354 Start mail input; end with <CRLF>.<CRLF> No error codes are present in the smtp logs, but I do trace the following event from the SMTP Mailer class: [Event type="mailError" bubbles=false cancelable=false eventPhase=2] When the condition is satisfied a third time, the email that was not delivered when the condition was satisfied the previous time is now delivered, along with the email for this instance. This pattern then repeats itself, with the next email not being sent followed by two emails being sent simulatneously when the condition is met again. The smtp server being used is Windows 2003, on an internal network. The email is being sent to an outlook account hosted on an exchange server that is also on this internal network. Here is the actionscript code that creates the SMTPMailer object: public var testMail:SMTPMailer = null; public function alertNotify() { Security.loadPolicyFile("crossdomain.xml"); this.testMail = new SMTPMailer("myserver.ec.local",25); this.testMail.addEventListener(SMTPEvent.MAIL_SENT, onEmailEvent); this.testMail.addEventListener(SMTPEvent.MAIL_ERROR, onEmailError); this.testMail.addEventListener(SMTPEvent.DISCONNECTED, onEmailConn); this.testMail.addEventListener(SecurityErrorEvent.SECURITY_ERROR, onEmailError); } Here is the code that creates the email body and calls the method to send the email: public function alertUser(emailAC:ArrayCollection):void { trace ("In alertUser() before send, testMail.connected = " + testMail.connected.toString()); var testStr:String = " Key Location Event Type Comment Update Time "; for each (var event:rEntity in emailAC) { testStr = testStr + "" + event.key.toString() + "" + event.xml.address.toString() + " " + [email protected]() + "" + [email protected]() + "" + [email protected]() + "" + event.xml.attribute("update-time").toXMLString() + ""; } testStr = testStr + ""; testMail.flush(); testMail.sendHTMLMail("[email protected]","[email protected]","Event Notification",testStr); } Really not sure where the email that gets hung up is being stored until it is finally sent.... Any suggestions as to how to begin to remedy this issue would be much appreciated.

  • Creating New Objects in JavaScript

    - by Ken Ray
    I'm a relatively newbie to object oriented programming in JavaScript, and I'm unsure of the "best" way to define and use objects in JavaScript. I've seen the "canonical" way to define objects and instantiate a new instance, as shown below. function myObjectType(property1, propterty2) { this.property1 = property1, this.property2 = property2 } // now create a new instance var myNewvariable = new myObjectType('value for property1', 'value for property2'); But I've seen other ways to create new instances of objects in this manner: var anotherVariable = new someObjectType({ property1: "Some value for this named property", property2: "This is the value for property 2" }); I like how that second way appears - the code is self documenting. But my questions are: Which way is "better"? Can I use that second way to instantiate a variable of an object type that has been defined using the "classical"way of defining the object type with that implicit constructor? If I want to create an array of these objects, are there any other considerations? Thanks in advance.
