  • Get all Select Elements in a Form by referencing $(this) instead of $("form select")

    - by DaveDev
    Hi Guys I'm currently getting all the Select elements that exist in a form with the following: $("form").submit(function(event) { // gather data var data = GetSelectData($("form select")); // do submit $.post($(this).attr("action"), data, ..etc) }); Instead of passing in $("form select"), is there a way I can say something like $(this).children('select') // this doesn't work, btw to get all the select elements that exist within the context of the form the submit event is executing for? This will allow me to reduce my code to the following, moving all the functionality into a common function: $("form").submit(function(event) { GatherDataAndSubmit($(this)); }); function GatherDataAndSubmit(obj) { var data = GetSelectData(obj.children('select')); $.post(obj.attr("action"), data, ..etc) } Thanks Dave

  • Create a Stream without having a physical file to create from.

    - by jhorton
    I'm needing to create a zip file containing documents that exist on the server. I am using the .Net Package class to do so, and to create a new Package (which is the zip file) I have to have either a path to a physical file or a stream. I am trying to not create an actual file that would be the zip file, instead just create a stream that would exist in memory or something. My question is how do you instantiate a new Stream (i.e. FileStream, MemoryStream, etc) without having a physical file to instantiate from.

  • overwrite a file which is already used by another process

    - by Ahmy
    I have a web site and i am showing videos to visitors, at the admin side i am filling the form of video and upload video file and sometimes i need to change(update) the video so i update the video by uploading another one, when i create the video in the first time i concatenate a datetime variable with the video name to avoid repeatition(file already exist) and when updatting the video the problem appears.... as if i upload the new video with the previous name so it will replace the previous one and in this case if the video is used by another process it will fail and the second option(which i am already using) is to upload a new video and concatenating new datetime variable with video title, so the previous and the new video will exist in the same directory and in this case i will lose too much space in my server directory as i have unused videos which takes space which in future will cause problem to me in the disk space so how can i solve this problem ? Hope that my question is clear....thanks in advance for any try

  • Cant set drop down list selected value in page load

    - by Ben
    Hi, I'm trying to set the selected value of a ddl during page load ie. before databind. This causes "selected value does not exist" errors. So I force a databind, and add a new element if it does not exist in the data source. However it looks like when the databind is performed later in the page lifecycle that my added element(s) are removed/overwritten. Am I setting the values in the wrong part of the life cycle? what I'm doing seems rather hackish and I think im going about this the wrong way... is there a better way to do this?

  • Wiki for requirements engineering

    - by Shanon
    Hi, I'm looking to to build a wiki based tool the helps/aides in the requirements engineering process. More specifically I am hoping to end up with a tool that helps inexperienced users easily create and design requirements documents on a wiki platform. I was wondering if there exist any wiki/wiki platforms that either already exist or are easily extendible or would be worth looking at that for this purpose. For instance some of the features I was hoping to add would be to add structure to a document so that information is filled out in a standardised manner. Another idea I was looking at was to somehow create relationships between different types of documents (for example- a goal diagram gets evolves/ helps in the development of the class diagram). So far I have come across FOSwiki which claims to to fully customisalble...but I'm not sure what it means and what I can really do with that. Any input on FOSwiki is also highly appreciated.

  • How should the Version field be used in Trac?

    - by Eric
    I use Trac to track bugs, and future changes in my software projects. Tickets in Trac have a "Version" field and I'm trying to figure out the best way to use this field. Say I find a series of bugs in version 1.0 of my software. I create tickets in track for each and assign them to version 1.0. Now say I fix some of the bugs, and add some of the new features and release version 1.1. But some of the old 1.0 bugs are still in 1.1. Should I change their corresponding tickets to version 1.1 because they also now exist in 1.1? Or should I leave them set to version 1.0 as a way of tracking what version the bug was found in, and just assume that any open tickets in older versions still exist in newer versions?

    - by bahamut100
    Hi, how to test if a file exist on the current computer using the application ? I try to put the full url at my file like this, but it doesn't work : if(file_exists("C:/wamp/www/project/photo/".$nom_photo)) { echo "file exist"; $extension=pathinfo("C:/wamp/www/project/photo/".$nom_photo,PATHINFO_EXTENSION); echo "<br>"; $nom=md5($nom_photo.time().rand(0, 99999)).".".$extension; echo $nom; rename("C:/wamp/www/project/photo/".$nom_photo,"C:/wamp/www/project/photo/".$nom); echo "<br>"; } How to fix it ?

  • View of nodes and their translations

    - by kratib
    I'm trying to create a view of nodes and their translations. Specifically, I want each row to show the node title for each language. The way I'm doing it right now is by filtering the view by a specific language, then adding one relationship of type "Node translation: Translations" for each language on the site. I can then choose the "Node: Title" field, once for the original language and once per relationship. The problem with this approach is that the nodes that don't exist in the filtered language, but exist in other languages, are not included in the view. That's what I need help with.

  • Linux friendly (.NET/Mono) browser object?

    - by HankB
    Hi folks, A friend of mine (familiar with C# and .NET on Windows) has asked how to port some functionality to a Linux host. This functionality is based on a JSP web page that fetches some data from the host server and displays it in a banner on a page. His Win/C#/.NET code simply creates a browser object which loads the page and he then inspects the resulting object to extract the data. I'm wondering what alternatives exist to duplicate this function on Ubuntu Linux. I'm not certain that the necessary libraries exist on this installation. I can assume that things like Perl and Python are ubiquitous, but I am not familiar with any libraries that include a browser object capable of executing javascript and exposing the results to another program. Any suggestions that lead in this direction are welcome. Thanks!

  • Android source referencing missing classes

    - by jqpubliq
    I cloned some of the trees from the Android Open Source Project to take a look at the code, but I can't build them because they reference classes which don't seem to exist. For instance, the music application here references android.media.MediaFile which according to the package summary does not exist, as well as things like ArrayListCursor which has an old javadoc around but is absent in current documentation. So is the open source project disjoint from the released SDK? Also, is there a way to build these open source packages with the current SDK? Thanks, -JQP

  • How to deploy a Java Swing application with an embedded JavaDB database?

    - by Jonas
    I have implemented an Java Swing application that uses an embedded JavaDB database. The database need to be stored somewhere and the database tables need to be created at the first run. What is the preferred way to do these procedures? Should I always create the database in the local directory, and first check if the database file exist, and if it doesn't exist let the user create the tables (or at least show a message that the tables will be created). Or should I let the user choose a path? but then I have to save the path somewhere. Should I save the path with Preferences.systemRoot();, and check if that variable is set on startup? If the user choses a path and save it in the Preferences, can I get any problems with user permissions? or should it be safe wherever the user store the database? Or how do I handle this? Any other suggestions for this procedure?

  • Use LINQ to count the number of combinations existing in two lists

    - by Ben McCormack
    I'm trying to create a LINQ query (or queries) that count the total number of occurences of a combinations of items in one list that exist in a different list. For example, take the following lists: CartItems DiscountItems ========= ============= AAA AAA AAA BBB AAA BBB BBB CCC CCC DDD The result of the query operation should be 2 since I can find two combinations of AAA and BBB (from DiscountItems) within the contents of CartItems. My thinking in approaching the query is to join the lists together to shorten CartItems to only include items from DiscountItems. The solution would be to find the CartItem in the resulting query that occurs the least amount of times, thus indicating how many combinations of items exist in CartItems. How can this be done? Here's the query I already have, but it's not working. query results in an enumeration with 100 items, far more than I expected. Dim query = From cartItem In Cart.CartItems Group Join discountItem In DiscountGroup.DiscountItems On cartItem.SKU Equals discountItem.SKU Into Group Select SKU = cartItem.SKU, CartItems = Group Return query.Min(Function(x) x.CartItems.Sum(Function(y) y.Quantity))

  • C# .NET Controls for docked tool windows?

    - by Brett Powell
    I was using Qt with C++ to develop my GUI applications, but I have recently switched to try out C# .NET as it is much easier to do what I need to. I was wondering what controls I need to be using for a few things and if they exist for C# .NET or if I need to do something custom/special. If you look in that screenshot, I want to do something similar to how they have each tool window grouped into its own docking area with the option of closing it or breaking it out of the layout so it can be dragged. I am talking about the tool windows titled "Groups", "Resources", "Tools", etc. I also want to make these tool windows stay in the same place when the main window is resized. Qt has spring like widgets that will let you create a UI that keeps its shape when the window is resized. Does anything like this exist in C# .NET?

  • Tooltip equivalent for touch devices?

    - by eteubert
    Hey folks, Touch devices are on the rise. More and more website developers try to optimize their pages for those devices. Until recently the most common solution was to build a mobile version for the website. But with tablets this will most likely change to adjusting the original pages to be touch compatible. One big issue I encountered are tooltips. There are some websites and web applications relying heavily on storing important informations in some kind of tooltip triggered by hovering the mouse arrow over some interface element - which does not exist on touch devices. So what do you think is a good universal way to adopt these pages without redesigning the site from scratch? Does this universal way even exist? My first idea was a tiny touchable question mark but this would hardly be big enough for a finger.

  • Replacing delimiter characters in file path

    - by salvationishere
    I'm developing a C# web application in VS 2008. I let the user select an input file and then I store the file path in a string variable. However, it stores this path as "C:\\folder\\...". So my question is how do I convert this file path into single "\"? To clarify more, this is my code in context. Currently it is entering the If Directory does not Exist section. protected void btnAppend_Click(object sender, EventArgs e) { string fullpath = Page.Request.PhysicalPath; fullpath.Replace('\\', '\'); if (!Directory.Exists(fullpath)) { string msg = "<h1>The upload path doesn't exist: {0}</h1>";

  • What's the best way to tell if a file exists in a directory?

    - by Nano HE
    I'm trying to move a file but I want to ensure that it exists before I do so. What's the simplest way to do this in Perl? My code is like this. I looked up the open command, but I am not sure it is the simplest way or not. if #Parser.exe exist in directory of Debug { move ("bin/Debug/Parser.exe","Parser.exe"); } elsif #Parser.exe exist in directory of Release { move ("bin/Release/Parser.exe","Parser.exe"); } else { die "Can't find the Parser.exe."; } Thank you.

  • How to unit test configs

    - by ForeverDebugging
    We're working with some very large config files which contain lots of Unity and WCF configuration. When we open some of these configs in the SVC config editor or even try to open a web application using these configs, we recieve errors showing any typos or errors. E.g. a WCF binding is invalid or does not exist etc, or a configuration section does not exist, two endding tags, etc. Is there some way to "valid" a config through a unit test? So there's one less thing which could go wrong when the application is moved into a new environment.

  • Create fake subdirectories with htaccess and php AND keep existing directories as is.

    - by Arseni
    I have a website, which has numerous subdirectories already. (All existing in server's filesystem) I want to create new "virtual" sub-dirs with htaccess, but I only want the htaccess rule work for directories, listed in DB, and not existing in filesystem. i.e. File system has: /dir1/ & /dir2/ MySQL database has record for 'dir3' & 'dir4' And I want: A: mysite.com/dir1/ and mysite.com/dir2/ display existing old content B: mysite.com/dir3/ and mysite.com/dir4/ display content from MySQL provided by PHP sctipt via redirect like: mysite.com/myscript.php?dir=dir3 C: mysite.com/dir5/ display 404 error (Dir does not exist in DB nor in Database) Basically I want .htaccess to work like this: IF DIR Exists in DB - apply the rewrite rule and show content from myscript.php?dir=DIR ELSE don't apply any rule. I can create a separate php script, which can return 0/1 when given dir name exist in DB or not, but how do I make mod_rewrite get the data from that script? Is it possible with htaccess/PHP at all?

  • Is there such a thing as a dektop application event aggregator, similar to that used in Prism?

    - by brownj
    The event aggregator in Prism is great, and allows loosely coupled communication between modules within a composite application. Does such a thing exist that allows the same thing to happen between standalone applications running on a user's desktop? I could imagine developing a solution that uses WCF with TCP binding and running inside Windows Process Activation Service. Client applications could subscribe or publish events to this service as required and it would ensure all other listeners get notified of events as appropriate. Using TCP would enable event messages to be pushed out to clients without the need for polling, ensuring messages are delivered very quickly. I can't help but think though that such a thing would already exist... Is anyone aware of something like this, or have any advice on how it may be best implemented?

    I am using the following code to check existence of a file before publishing an image in my erb file. <% @imagename = @place.name + ".jpg" %> <% if FileTest.exist?( "/Users/Tim/projects/game/public/" + @imagename ) %> <p><img src= '<%= @imagename %>' width="400" height="300" /> </p> <% end %> And when I publish this to Heroku, it obviously wont work. I tried using a relative path, but not able to get it to work. <% if FileTest.exist?( "/" + @imagename ) % any help appreciated.

  • COUNT issue across multiple tables

    - by Kim
    I am trying to count across 2 tables and I dont see whats wrong with my query yet I get a wrong result. User 2 does not exist in table_two, so the zero is correct. SELECT t1.creator_user_id, COUNT(t1.creator_user_id), COUNT(t2.user_id) FROM table_one AS t1 LEFT JOIN table_two AS t2 ON t2.user_id = t1.creator_user_id GROUP BY t1.creator_user_id, t2.user_id Actual result 1 192 192 2 9 0 Expected result 1 16 12 2 9 0 The result indicate a missing group by condition, but I already got both fields used. Where am I wrong ? Also, can I sum up all users that doesnt exist in table_two for t1 ? Like user 3 exists 21 times in t1, then the results would be: 1 16 12 (users with > 0 in t2 will need their own row) 2 30 0 (user 2=9 + user 3=21 => 30) Its okay for the user Id to be wrong for sum of t1 for all users with 0 in t2. If not possible, then I'll just do two queries.
