  • Can a Client Link to My JavaScript, Hosted on a Different Domain?

    - by DaveDev
    Is it possible for me to supply a client with a snippet of HTML which contains a reference to a javascript file that I host? They want to paste this HTML into their CMS, so that when their page loads, it'll load our content. I was under the impression that there was cross domain security preventing this from being possible. What if, instead of linking to the JavaScript, I gave them the snippet of HTML with the JavaScript already included so instead of <div> <!-- link to js --> </div> I gave them <div> $.get(/*url to my content*/); </div> Would that work?

  • How does one SELECT block another?

    - by Krip
    I'm looking at output of SP_WhoIsActive on SQL Server 2005, and it's telling me one session is blocking another - fine. However they both are running a SELECT. How does one SELECT block another? Shouldn't they both be acquiring shared locks (which are compatible with one another)? Some more details: Neither session has an open transaction count - so they are stand-alone. The queries join a view with a table. They are complex queries which join lots of tables and results in 10,000 or so reads. Any insight much appreciated.

  • iOS: How to access the `UIKeyboard`?

    - by MattDiPasquale
    I want to get a pointer reference to UIKeyboard *keyboard to the keyboard on screen so that I can add a transparent subview to it, covering it completely, to achieve the effect of disabling the UIKeyboard without hiding it. In doing this, can I assume that there's only one UIKeyboard on the screen at a time? I.e., is it a singleton? Where's the method [UIKeyboard sharedInstance]. Brownie points if you implement that method via a category. Or, even more brownie points if you convince me why it's a bad idea to assume only one keyboard and give me a better solution.

  • PHP DOMElement, replacing text of a node

    - by waitinforatrain
    I have a HTML node like so: <b>Bold text</b> A variable $el contains a DOMElement reference to the text of that HTML node ("Bold text"), got from the XPath expression //b/text() I want to change the element to <b><span>Bold Text</span></b> So I tried: $span = $doc->createElement('span', "Bold Text"); $el->parentNode->replaceChild($span,, $el) which fails because parentNode is null. So, as a test, I tried: $el-insertBefore($span, $el); which throws no errors but produces no change in the output. Any thoughts?

  • Sharepoint 2007 and <!DOCTYPE html>

    - by Kondor
    Greetings... I'm trying to get my Sharepoint 2007 site to render in Standards mode when browsing in IE. Since makes every browser that I might be worrying about do just that, I decided to use it. I've read here and there that Standards mode could cause unwanted behavior to some OOTB functionality and style (fly-outs, calendar items, etc...), but can't find a full list containing error reference and ways to correct it. So, I'm looking for any kind of info and guidance on the matter... Just trying to avoid endless clicking through my app and hopping that some one altruistic by nature has gone through testing hell already and is willing to share. Thanks...

  • NSURLConnection shown as leaking in instruments

    - by Gyozo Kudor
    Hello another stupid question regarding leaks and also NSURLConnection. How do i release it? Is it enough if i release in the following 2 methods? (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error (void)connectionDidFinishLoading:(NSURLConnection *)connection Because in instruments it shows me the line where I alloc my connection as the source of leaking. OK I don't get it. After the following code my urlConnection has a retain count of 2. WTF? NSURLConnection *urlConnection = [[NSURLConnection alloc] initWithRequest: urlRequest delegate: self]; This is the line that instruments points me to. I find this very weird.

  • Naudio - putting audio stream into values [-1,1]

    - by denonth
    Hi all I need to put my audio stream into values of [-1,1]. Can someone tell me a good approach. I was reading byte array and float array from stream but I don't know what to do next. Here is my code: float[] bytes=new float[stream.Length]; float biggest= 0; for (int i = 0; i < stream.Length; i++) { bytes[i] = (byte)stream.ReadByte(); if (bytes[i] > biggest) { biggest=bytes[i]; } } and I don't know how to put values into stream. Because byte is only positive values. And I need to have from [-1,1] for (int i = 0; i < bytes.Count(); i++) { bytes[i] = (byte)(bytes[i] * (1 / biggest)); }

  • How to filter entities by their parents in ManyToOne side in Google App Engine

    - by palto
    I use Google App Engine. When I try to do a JPA query like this: "SELECT p FROM Participant p WHERE p.party.id = :partyKey AND p.name=:participantName" I get the following error Caused by: org.datanucleus.store.appengine.FatalNucleusUserException: SELECT FROM Participant p WHERE p.party.id = :partyKey AND p.name=:participantName: Can only reference properties of a sub-object if the sub-object is embedded. I gave the key of the Party object as a parameter to the "partyKey" named parameter. The model is like this: Party has multiple Participants. I want to query a participant based on the party and the name of the participant. I just can't figure out how to filter using the party. What options do I have?

  • How can I use SVN to manage my Firefox Extension project?

    - by 4AM
    I'm using SVN to manage my Firefox extension project, and this project contains an XPCOM component. Firefox is loading directly from my working directory by placing a text file with the working directory's path in the ./extensions directory of my user profile. When Firefox starts, my extension fails to load & overlay; examining the Error Console, I see that the error states that ".svn cannot be loaded as a component" - a reference to the .svn directory inside my "components" directory of the plug-in structure. Is there any way to get Firefox to ignore this directory, or get SVN to generate a working copy without the .svn directories in it?

  • Generate combinations by order and fixed length.

    - by roconmachine
    Suppose there is array main[] = [a,b,c,....z]; a[] = [a1,a2,a3,....] , b[] = [b1,b2,b3,....] and so on. So if we generate combination in main.length of ordered then it looks like ..... a1 b1 c1, a1 b1 c2, a1 b1 c3 ...... a1 b2 c1, a1 b3 c1, ..... a2 b1 c1, a3 b1 c1, ..... and total count will be a.length * b.length * c.length ........ = ? So write a code in any language to generate those combination. all the best. alex

  • retrieve columns from sqlite3

    - by John Smith
    I have two tables in sqlite: CREATE TABLE fruit ('fid' integer, 'name' text); CREATE TABLE basket ('fid1' integer, 'fid2' integer, 'c1' integer, 'c2' integer); basket is supposed to have count c1 of fruit fid1 and c2 of fruit fid2 I created a view fruitbasket; create view fruitbasket as select * from basket inner join fruit a on a.fid=basket.fid1 inner join fruit b on b.fid=basket.fid2; it works (almost) as expected. When I type pragma table_info(fruitbasket); I get the following output 0|fid1|integer|0||0 1|fid2|integer|0||0 2|c1|integer|0||0 3|c2|integer|0||0 4|fid|integer|0||0 5|name|text|0||0 6|fid:1|integer|0||0 7|name:1|text|0||0 The problem is that I cannot seem to SELECT name:1. How can I do it other than going back and re-aliasing the columns?

  • border highlighting loop with jquery

    - by Tek
    I'm having trouble coming up with a loop that changes the border color of an image from black to yellow and yellow to black over x seconds. Then applying an interrupt to the loop when the image gets clicked on. I don't know where to start, can someone point me in the right direction? I think I may be using the wrong tools to properly write this. Here's what I've come up so far, though if there's a better way to write this, do share! for( i = 100; i >= 0; i--) { $("#imgid").css("border-color", 'rgb(' + i + '%,' + i + '%,0)'); } I'm having trouble picturing how I could combine two loops so that I can also count upwards as well so that it will turn into yellow and back to black. I also don't know how to go about controlling the amount of time it takes for that loop to execute and creating an interrupt when #imigid is clicked. Which is where I'm not sure how to write.

  • Is this a valid benefit of using embedded SQL over stored procedures?

    - by George
    Here's an argument for SPs that I haven't heard. Flamers, be gentle with the down tick, Since there is overhead associated with each trip to the database server, I would suggest that a POSSIBLE reason for placing your SQL in SPs over embedded code is that you are more insulated to change without taking a performance hit. For example. Let's say you need to perform Query A that returns a scalar integer. Then, later, the requirements change and you decide that it the results of the scalar is x that then, and only then, you need to perform another query. If you performed the first query in a SP, you could easily check the result of the first query and conditionally execute the 2nd SQL in the same SP. How would you do this efficiently in embedded SQL w/o perform a separate query or an unnecessary query? Here's an example: --This SP may return 1 or two queries. SELECT @CustCount = COUNT(*) FROM CUSTOMER IF @CustCount 10 SELECT * FROM PRODUCT Can this/what is the best way to do this in embedded SQL?

  • An Inaccessible JavaScript Object property - Why is Firebug showing this?

    - by Matty
    So, I'm attempting to access the content of an object and for the life of me can't figure out why I can't. I'm starting to believe that the object doesn't have the properties that Firebug indicates that it does. More likely than that I'm just not using the right syntax to access them. Give the following function: function(userData) { console.log(userData); // statement 1 console.log(userData.t_nodecontent); // statement 2 } Which generates the following FireBug output for statement 1 and unknown for statement 2. Is there something obvious that I'm overlooking in the way I'm attempting to reference the value of t_nodecontent? I'm at a loss :(

  • What are some useful SQL statements / usage patterns that should be known by all developers who may

    - by Jian Lin
    What are some useful SQL statements that should be known by all developers who may touch the Back end side of the project? (Update: just like in algorithm, we know there are sorting problems, shuffling problems, and we know some solutions to them. This question is aiming at the same thing). For example, ones I can think of are: Get a list of Employees and their boss. Or one with the employee's salary greater than the boss. (Self-join) Get a list of the most popular Classes registered by students, from the greatest number to the smallest. (Count, group by, order by) Get a list of Classes that are not registered by any students. (Outer join and check whether the match is NULL, or by Get from Classes table, all ClassIDs which are NOT IN (a subquery to get all ClassIDs from the Registrations table)) Are there some SQL statements that should be under the sleeve of all developers that might touch back end data?

  • Displaying a collection of controls in a specific way in WPF

    - by Alvaro
    I have a collection of controls "MyCollection" wich changes in the Runtime. And I have to follow some constraints for that, for example: If my parameter "MyCollection.Count = 4" the property "NumberOfcolumns" will have the value 2, in order to create new Lines, and show the controls Two per Two. This is how I'm displaying my collection : <ItemsControl ItemsSource="{Binding MyCollection}" BorderThickness="0" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" > <ItemsControl.ItemsPanel> <ItemsPanelTemplate > <UniformGrid Columns="{Binding NumberOfColumns}" VerticalAlignment="Center" HorizontalAlignment="Center" Background="Transparent"/> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> </ItemsControl> The problem is that my controls have different sizes, and as In UniformGrids, Cells are uniform... My design is not really pretty, because I have little controls shown in big Cells !! Can someone help me to solve this problem ? NB: Please give me a detailled solution if possible, not something like : "Use WrapPanel..."

  • How do I avoid boxing/unboxing when extending System.Object?

    - by Robert H.
    I'm working on an extension method that's only applicable to reference types. I think, however, it's currently boxing and unboxing the the value. How can I avoid this? namespace System { public static class SystemExtensions { public static TResult GetOrDefaultIfNull<T, TResult>(this T obj, Func<T, TResult> getValue, TResult defaultValue) { if (obj == null) return defaultValue; return getValue(obj); } } } Example usage: public class Foo { public int Bar { get; set; } } In some method: Foo aFooObject = new Foo { Bar = 1 }; Foo nullReference = null; Console.WriteLine(aFooObject.GetOrDefaultIfNull((o) => o.Bar, 0)); // results: 1 Console.WriteLine(nullReference.GetOrDefaultIfNull((o) => o.Bar, 0)); // results: 0

  • iPhone - Image overlay MapKit framework?

    - by Peter
    I can see with iOS4 you can now tile an image on google maps (Been looking at the TileMap example from apple). This is great as this is what I want to do, but from what I can see I need to know the GEO reference of the image so I can raster the images with the appropriate zoom levels, etc. What I have is an artist image, which is a map of a specific area and I want to overlay this image on google maps. Am I missing something here, but can this be done with a none standard map and having different zoom levels? The main reason why I need to use google maps is because of the GPS functionality, so the user will know where they currently are on the map.

  • Why is the dictionary debug visualizer less useful in Visual Studio 2010 for Silverlight debugging?

    - by Kevin
    I was debugging in Visual Studio 2010, which we just installed and trying to look at a dictionary in the quick watch window. I see Keys and Values, but drilling into those shows the Count and Non-Public members, Non-Public members continues the trail and I never see the values in the dictionary. I can run test.Take(10) and see the values, but why should I have to do that. I don't have VS 2008 installed anymore to compare, but it seems that I could debug a dictionary much easier. Why is it this way now? Is it just a setting I set somehow on my machine? Test code: Dictionary<string, string> test = new Dictionary<string, string>(); test.Add("a", "b"); EDIT: I've just tried the same debug in a Console app and it works as expected. The other project is a Silverlight 4 application, why are they different? Console Debug Screen Shot Silverlight 4 Debug Screen Shot:
