• Attach an HREF and a class to an img link generated by the PhotoSlider script?

  - by Frank Bailey

  Hi folks, I'm using the very nice PhotoSlider script from http://opiefoto.com/articles/photoslider to create a slide show of images for one of my clients. This script replaces a previous hand-coded Javascript solution that allowed for the large image to be clicked resulting in a lightbox modal popup showing the full-size version of the clicked picture. Of course the client insists that this functionality remain intact, but the HTML code for the large image is generated on-the-fly by the PhotoSlider script itself. This means I'll need to modify the script slightly to attach a class ("lightbox") and an href (or just a click event, whichever makes more sense), but I'm not quite sure how best to accomplish this. I figure the event and class will have to be attached each time a thumbnail is clicked, but if this isn't the best way to do it any advice will be appreciated. The script is implemented into my page as can be seen here, without the click or class. I'd really appreciate any assistance stackoverflowites can offer. Thanks in advance!

• Different icons and title for same iPad application

  - by trapo

  I'm developing an iPad application that will be distributed "in-house" ie only inside enterprise. They asked me if i can produce 2 different releases of the same application to be installed on the same iPad. The first one will communicate with a production server while the second will use a sandbox server and will be used by user to learn the system. Server url will be changed in app settings. They told me to differentiate these releases by icon and title (and also, of course, by title in navigation bar). What's the best way to get this goal avoiding duplication of the project?

• How do you get speech dictated without adding it to a grammar list?

  - by joe

  I'm new to Speech Recognition, and I'm working on a project that will receive a command from a recognizable list. For example, I would say "Play song". The computer would ask the song title, and I can say it. It will then compare my answer to my music library and find it. I know how to add recognizable grammar to the SpeechRecognizer object, how to make the computer speak, and how to play a song in iTunes. I cannot, however, figure out how to get it to dictate or listen and interpret something that isn't in the grammar list. Is there a method I'm missing? Or not yet been simplified by Microsoft? I have no code to show for this, as I am not even sure how to search for this particular idea. Of course, I could have the program read my entire library, but that's not an optimal solution considering I have tens of thousands of songs. Thanks in advance!

• How do I make my horizontally scrolling page work in IE?

  - by Jessica

  I am using a horizontal scroll for a page on my website ~ works great in FF but not in IE, how can i get it to work in IE? Here is the JS that I have in the head of my html: <script src="js/jquery-1.2.6.min.js" type="text/javascript" charset="utf-8"></script> <script type="text/javascript" charset="utf-8"> $(function(){ $("#page-wrap").wrapInner("<table><tr>"); $(".post").wrap("<td>"); });</script> There is also of course the other script file, but its huge so I'm not going to post it here. Is there a hack or something I can use to get it to scroll correctly in IE? Thx in advance!

• Is it possible to creating a Service without starting it?

  - by ThaMe90

  Hello all, I wonder, is it possible to create a Service, set some data, and then start it? I haven't come across a thread specific to this problem, so I would like to know if it is possible (if it is known of course). My problem is that I have a Service which listens to a DatagramSocket, but the socket in question needs to be set after creation, but before the start of the Service. The setting of the socket happens through the use of a Broadcast (I broadcast 2 Strings which hold the IP-Address & Port and the BroadcastReceiver then constructs a socket for me). When the Service is started, a Thread will start to run and listen to the supposedly created socket. This, sadly, doesn't happen. The socket will remain null and I can't set it when the Thread is running (This is another issue I hope to tackle in the future, if anybody got any ideas about this, please notify me). So, is what I want possible, or should I come up with another construct for achieving this goal?

• Why can't I open a new window on my jquery ajax callback?

  - by KyleGobel

  to show my problem in a couple examples... THIS WORKS $.post("SomePage.aspx", { name : "value" }, function (data) { alert(data); }, "text"); THIS DOESN'T WORK $.post("SomePage.aspx", { name : "value" }, function (data) { window.open("http://www.google.com"); }, "text"); In the first example, I get alerted with what i'm expecting. In the second example, nothing happens. No window is opened. If I add an alert or something before or after the window.open call, the alert works fine, but the window doesn't open. If I add a window.open completly after the $.post method, the window opens fine (of course this doens't help me at all). I'm wondering why I can't open a window in the callback. What do I have to do to be able to open a window? I'd like to open a window to show some fancy results. Any help is appreciated, thanks.

• Display indented XML code within a HTML page

  - by Efrain

  I have a programmatically created HTML document on which I would like to show some XML-code, fully formatted with line breaks and tabulators. That is, it should look like if you drag an xml file without a xml-stylesheet directly onto your browser (most browsers do some kind of xml-rendering with some default style sheet). Now, I can of course escape all the characters (like <>, tab and newline) and do the indenting myself (using css styles, for example), but I was wondering whether I couldn't re-use some 'default' xml-stylesheet from somewhere. Preferrably also one that has some javascript node-folding, too. Do you know such a stylesheet/xslt? Or would you suggest another way to achieve this? I'm using C#. PS: I tried to use the XmlNotepad.DefaultSS.xslt from Microsoft's XmlNotepad, but I couldn't really get that working. :T

• Get file size of BufferedImage before writing the data

  - by David

  I'm working on a Java program that needs to send an image (preferably in PNG format, though I could perhaps use another format if necessary) over the network. The logical way to do this is, of course, to first send the length of the PNG image data, then the data itself. Problem: I don't see any method in ImageIO or anywhere else that will give me the length of the image data. Does this exist somewhere in the Java 1.6 standard library? I know I could just write it to a ByteArrayOutputStream and get the length of the resulting array, but before resorting that I wanted to make sure I'm not missing something built in. And besides, that makes an extra copy of the image data, which I'd rather not do if it's not necessary.

• Core Data not-reverse relationship subquery

  - by user561485

  Hi, I have the following entities in CoreData: Village - villageID Bookmark - (relation) village There are multiple villages with each an unique villageID. I have a entity Bookmark which only has a relation to a Village entity; it isn't possible to make a reverse relation. Now I would like to get the village entities where there exists a Bookmark relation. I've red something about subqueries, but I can't get it right for this situation. It must be something like: Village.villageID IN (Bookmark.village.villageID) It isn't possible to get first all the Bookmarks and then loop to get all the Villages, because of the design of the framework. Can this be done in CoreData (I presume the answer is "Yes, of course!") and how?

• Efficient determination of which strings in an array are substrings of the others?

  - by byte

  In C#, Say you have an array of strings, which contain only characters '0' and '1': string[] input = { "0101", "101", "11", "010101011" }; And you'd like to build a function: public void IdentifySubstrings(string[] input) { ... } That will produce the following: "0101 is a substring of 010101011" "101 is a substring of 0101" "101 is a substring of 010101011" "11 is a substring of 010101011" And you are NOT able to use built-in string functionality (such as String.Substring). How would one efficiently solve this problem? Of course you could plow through it via brute force, but it just feels like there ought to be a way to accomplish it with a tree (since the only values are 0's and 1's, it feels like a binary tree ought to fit somehow). I've read a little bit about things like suffix trees, but I'm uncertain if that's the right path to be going down. Any efficient solutions you can think of?

• The best practice to setup hierarchy data

  - by eski

  I'm trying to figure out the best practice to setup hierarchy data that i take from a database into some contoller that would show the hierachy. Basicly this would look like a normal tree but when you press the items that are under "chapters" you get a link to another page. I have these tables and this is the way they are connected Period Courses Subjects Chapters I select Period from a DropDownBox and then i want all the courses in that period to line up. Under each course would be the subject and under them are the chapers, typical hierarchy. The tables are linked together with refrences to each other in linear way. I have tried to use treeview to show this, but dont understand how to do it. I though i could use <ul><il> tags and do it at runtime. Reapeter or datalist, possible ? Is it better to do this with databinding in XAML or in code ?

• Restricting deletion with NHibernate

  - by FrontSvin

  I'm using NHibernate (fluent) to access an old third-party database with a bunch of tables, that are not related in any explicit way. That is a child tables does have parentID columns which contains the primary key of the parent table, but there are no foreign key relations ensuring these relations. Ideally I would like to add some foreign keys, but cannot touch the database schema. My application works fine, but I would really like impose a referential integrity rule that would prohibit deletion of parent objects if they have children, e.i. something similar 'ON DELETE RESTRICT' but maintained by NHibernate. Any ideas on how to approach this would be appreciated. Should I look into the OnDelete() method on the IInterceptor interface, or are there other ways to solve this? Of course any solution will come with a performance penalty, but I can live with that.

• How can we protect ourselves from other third parties installing DLLs with the same names as some of

  - by Integer Poet

  Our product includes several DLLs built from open source into files with default names as delivered by the open source developers. We're careful to install the files in our own directories and we carefully manage the search path (only for our processes) to keep the loader happy. Another developer -- a towering intellect -- decided it would be easier to install their own build of some of the same open source into C:\WINDOWS under the same default DLL filenames. Consequently, when we launch a process which depends on these open source DLLs, the system searches C:\WINDOWS before our directories and finds the DLLs installed by the other developer. And they are, of course, incompatible. Ideas which have occurred to me so far: rename all our DLLs to avoid the default names, which would only make it less likely we would encounter collisions load all our DLLs by full path so the loader captures their names into RAM and doesn't search anywhere else the next time they are requested For various reasons, neither of these options is palatable at the moment. What else can we do to defend ourselves against the towering intellects of the world?

• Simple integer encryption

  - by tloflin

  Is there a simple algorithm to encrypt integers? That is, a function E(i,k) that accepts an n-bit integer and a key (of any type) and produces another, unrelated n-bit integer that, when fed into a second function D(i,k) (along with the key) produces the original integer? Obviously there are some simple reversible operations you can perform, but they all seem to produce clearly related outputs (e.g. consecutive inputs lead to consecutive outputs). Also, of course, there are cryptographically strong standard algorithms, but they don't produce small enough outputs (e.g. 32-bit). I know any 32-bit cryptography can be brute-forced, but I'm not looking for something cryptographically strong, just something that looks random. Theoretically speaking it should be possible; after all, I could just create a dictionary by randomly pairing every integer. But I was hoping for something a little less memory-intensive.

• What is the accepted way to replace java.util.Date(year,month,day)

  - by dagw

  I'm trying to do something really simple, but starting to realize that dates in Java are a bit of minefield. All I want is to get passed groups of three ints ( a year, a month and a date) create some Date objects, do some simple test on them (along the lines of as date A before date B and after January 1 1990), convert them to java.sql.Date objects and pass them off to the database via JDBC. All very simple and works fine using the java.util.Date(int year,int month,int day) constructor. Of course that constructor is depreciated, and I'd like to avoid using depreciated calls in new code I'm writing. However all the other options to solve this simple problem seem stupidly complicated. Is there really no simple way to do what I want without using depreciated constructors? I know the standard answer to all Java date related questions is "use joda time", but I really don't want to start pulling in third party libraries for such a seemingly trivial problem.

• Query with multiple IN-statements but without the cartesian product

  - by Janne

  How could I make this kind of query e.g. in MySQL SELECT * FROM Table t WHERE t.a IN (1,2,3) AND t.b IN (4,5,6) AND t.c IN (7,8,9) ... so that the result would contain only the three rows: t.a|t.b|t.c ---+---+--- 1 | 4 | 7 2 | 5 | 8 3 | 6 | 9 The above query of course returns all the combinations of the values in the IN clauses but I would like to get just the ones where the first elements of each tuple match, second elements of each tuple match and so on. Is there any efficient way to do this? By the way is there some common term for this kind of query or concept? I'm having hard time coming up with the question's title because I can't put this into words..

• Django: HTTPS for just login page?

  - by Mark

  I just added this SSL middleware to my site http://www.djangosnippets.org/snippets/85/ which I used to secure only my login page so that passwords aren't sent in clear-text. Of course, when the user navigates away from that page he's suddenly logged out. I understand why this happens, but is there a way to pass the cookie over to HTTP so that users can stay logged in? If not, is there an easy way I can use HTTPS for the login page (and maybe the registration page), and then have it stay on HTTPS if the user is logged in, but switch back to HTTP if the user doesn't log in? There are a lot of pages that are visible to both logged in users and not, so I can't just designate certain pages as HTTP or HTTPS.

• Flex RGBA colors in CSS

  - by jscheel

  Hello all, I am trying to style a DataGrid component so that the background is transparent (Flex 4). Rgba colors work fine if I make "alternatingItemColors" an attribute on the component, but if I try to declare it in my css stylesheet, I cannot declare the alpha value. Works (mxml): <mx:DataGrid id="songGrid" width="800" height="529" dataProvider="{songs}" itemClick="handleRowClick(event);" x="145" y="168" headerStyleName="dataGridHeader" alternatingItemColors="[0xFFFFFFFF, 0xFFFFFFFF]"> Doesn't Work (css): mx|DataGrid { alternatingItemColors: #FFFFFFFF, #FFFFFFFF; } If I enter the values as "0xFFFFFFFF", I get a parse error, because it's not proper css (of course, most of flex's css isn't proper css, but I digress...). So, is there any way to declare the alpha value of these colors in the css?

• C# Array Maximum

  - by Betamoo

  I have 2 arrays named Arr1 and Arr2 in C#. They are of the exact same dimensions... I need to get the element of Arr1 corresponding to maximum of elements in Arr2 beginning with given indices ... e.g Get indices of the max of Arr2 [ 1 , 10 , 3 , i , j ] for all i,j Return Arr1 [ 1 , 10 , 3 , i , j ] Of course I need the elegant solution (not the "loop for them" one...) Please Note: I do not want to loop through the arrays, because it is 11 dimensional!!.. the code will be ugly and error prone.. and I may run out of variable names :)

• Unique identification string in php

  - by NardCake

  Currently me and my friend are developing a website, for what we will call 'projects' we just have a basic auto increment id in the database used to navigate to projects such as oururl.com/viewproject?id=1 but we started thinking, if we have alot of posted projects thats going to be a LONG url. So we need to somehow randomly generate a alphanumerical string about 6 characters long. We want the chance of the string being duplicated being extremely low and of course we will query the database before assigning an identifier. Thanks for anyhelp, means alot!

• Something wrong with deinstallation of GIT in Windows...

  - by Stef Joosten

  I tried to remove GIT on my windows-XP, by means of the Windows/Configuration/Software menu. After some error message (which I cannot remember), it removed all files. I checked it, and there are no files with ptp in the name left on the entire system. A problem remained however: each time I opened windows-explorer, a nasty error message came calling for a dll file that wasn't there anymore. Anyone know what is going on here? A wild guess: could there be any interference between svn and git, if certain files are linked to both git and svn? Personally, I went to the registry. I found that many traces to GIT are left in the registry after deinstalling GIT the "windows-way". I removed each one carefully by hand, which seems to have solved my problem. This is of course a dangerous path, but I had no choice. Perhaps it is a good idea to look into the Windows-deinstallation script very carefully.

• Position DIV relative to containing DIV Without Moving Other Stuff

  - by yar

  [I'm not sure if this question has been asked, though I've looked around a bit.] I have a DIV inside a DIV. I would like the inner DIV to have a certain position inside the outer div. I'm having some success with this position: absolute; top: 0px;right:0px; but all other divs are getting moved around. I just want it to float on top of the other stuff (float didn't work, of course). Thanks! Edit: The outer div is relative, and I'd like the inner to move with it when the browser is resized. Edit: Sorry, I've figured out the question (but not the answer): if I use right:0px, the inner div stops moving relative to the outer div and starts moving relative to the browser window. Why would that be?

• How to get notified of modification in the memory in Linux

  - by Song Yuan

  In a userspace program in Linux, I get a piece of memory via allocation from the heap, then the pointer is distributed to a lot of other components running in other threads to use. I would like to get notified when the said piece of memory is modified. I can of course develop a custom userspace solution for other components to use when they try to modify the memory. The problem in my case is that these are legacy components and they can write to memory in many occasions. So I'm wondering whether there is a similar API like inotify (get notified when file is changed) or other approaches in order to get notified when a piece of memory is changed. I considered using mmap and inotify, which obviously won't work if the changes are not flushed. Any suggestions are appreciated :-)

• I'm a PHP programmer, how easy will it be to "master" c++?

  - by ThinkingInBits

  I've been a PHP programmer for 8 or so years, I'm familiar with OOP and try to consider best practices whenever programming. I would like to pick up C++ to possibly enter the 'game development' field, where now I'm doing web dev. I'm not a school person, but was wondering what people think about self-taught math to complement learning c++ for game dev. The last math course I took was algebra 2. Should I start delving myself into pre-calculus? Are there any other suggestions you may have to ease the process?
