  • how to save xml files using Javascript?

    - by user311884
    Dear friends, I tried to 1) load an xml file using javascript as an object, say "note.xml" 2) then save the object to a new xml file, say "note_new.xml" I did 1) but failed 2) I tried to use method save() to do 2). After my failure, I checked ms site and they said save() is not supported.... could some one enlighten me how to do the save? thank you! here is the code: <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/> </head> <body> <h1>W3Schools Internal Note</h1> <p><b>To:</b> <span id="to"></span><br /> <b>From:</b> <span id="from"></span><br /> <b>Message:</b> <span id="message"></span> <script type="text/javascript"> if (window.ActiveXObject){ alert("there is ActiveXObject"); var xmlDoc = new ActiveXObject("Microsoft.XMLDOM"); xmlDoc.async=false; xmlDoc.load("note.xml"); }else{ alert("i am not withActiveXObject!"); xhttp=new XMLHttpRequest(); xhttp.open("GET","note.xml",false); xhttp.send(""); xmlDoc=xhttp.responseXML; } xmlDoc.save("note_new.xml"); </script> </body> </html> update: seems this is related to security issue. I appologize to those experienced programmers for my putting this question in a rush because it seems a newbie question.

  • Storing third-party libraries in source control

    - by graham.reeds
    Should libraries that the application relies on be stored in source control? One part of me says it should and another part say's no. It feels wrong to add a 20mb library that dwarfs the entire app just because you rely on a couple of functions from it (albeit rather heavily). Should you just store the jar/dll or maybe even the distributed zip/tar of the project? What do other people do?

  • Idiomatic Python: 'times' loop

    - by perimosocordiae
    Say I have a function foo that I want to call n times. In Ruby, I would write: n.times { foo } In Python, I could write: for _ in xrange(n): foo() But that seems like a hacky way of doing things. My question: Is there an idiomatic way of doing this in Python?

  • C# Loading a xml file from the current directory?

    - by Jonathan Dyle
    Hi all, I use the line below in my C# winform app, this works great but occasionally if the program is being run from the command line I get an error that the config.xml file cannot be found. This is because the 'working directory' is different (I think), I need to say "load config.xml from current directory", how would I do this? docXML.Load("config.xml"); Thanks Jonathan

    - by ggfan
    I want to upload my site public so people can use it. I am currently using a free PHP webhosting company that supports up to a certian amount. When sites that say they offer unlimited upload, data, etc for like $10/month, is that all you need to run a big site? Or how do I host a big site, if it gets popular?

  • SQLite is the CASE statement expensive?

    - by galford13x
    I'm wondering if using a CASE statement in SQLite (or other SQL engines) to replace data is not advised. For example lets say I have a query. SELECT Users, CASE WHEN Active = 0 THEN 'Inactive' WHEN Active = 1 THEN 'Active' WHEN Active = 2 THEN 'Processing' ELSE 'ERROR' AS Active FROM UsersTable; When is it better to create a reference table and perform a JOIN. In this case I would create a Table 'ActiveStatesTable' with ActiveID, ActiveDescription and perform the JOIN.

  • Core-Data + AFNetworking + UI Updating (Responsiveness)

    - by Mustafa
    Here's the scenario: I'm writing a DownloadManager, that allows the user to download, pause, cancel, download all, and pause all. The DownloadManager is a singleton, and uses AFNetworking to download files. It has it's own private managed object context, so that user can freely use other parts of the application (by adding, editing, deleting) core-data objects. I have a core-data entity DownloadInfo that stores the download information i.e. fileURL, fileSize, bytesRead, etc. The DownloadManager updates the download progress in DownloadInfo (one for each file). I have a DownloadManagerViewController which uses NSFetchedResultsController to show the download status to the user. This download view controller is using the main managed object context. Now let's say that I have 20 files in the download queue. And let's say that only 3 concurrent downloads are allowed. The download manager should download the file, and show the download progress. Problem: The DownloadInfo objects are being updated by the DownloadManager at a very high rate. The DownloadManagerViewController (responsible for showing the download progress) is updating the list using NSFetchedResultsControllerDelegate methods. The result is that a lot is happening in the main queue and application has very poor responsiveness. How can I fix this? How can I make the application responsive, while showing the download progress? I don't know how else to communicate that the download status between DownloadManager and DownloadManagerViewController. Is there another/ a better way to do this? I don't want to use main managed object context in my DownloadManager, for reasons mentioned above. Note, that the DownloadManager is using AFNetworking which is handling the requests asynchronously, but eventually the DownloadInfo objects are updated in the main thread (as a result of the callback methods). Maybe there's a way to handle the downloads and status update operations in a background thread? but how? How will I communicate between the main thread and the background thread i.e. how will I tell the background thread to queue another file for download? Thanks.

  • Migration of virtual machines

    - by Friedrich
    Are there tools for migrating from one virtual machine type to another? E.g let's say I have some Xen virtual machine and like to make it run under KVM. I know that qeumu has tools which can be used to "migrate" such machines, but how about: Xen - Kvm Kvm - Xen Xen - VMware (server?)

  • Sliding window algorithm for activiting recognition MATLAB

    - by csc
    I want to write a sliding window algorithm for use in activity recognition. The training data is <1xN so I'm thinking I just need to take (say window_size=3) the window_size of data and train that. I also later want to use this algorithm on a matrix . I'm new to matlab so i need any advice/directions on how to implement this correctly.

  • Java regex return after first match

    - by user216915
    hi how do i return after the first match of regular expression? (does the Matcher.find() method do that? ) say I have a string "abcdefgeee". I want to ask the regex engine stop finding immediately after it finds the first match of "e" for example. I am writing a method to return true/false if the pattern is found and i don't want to find the whole string for "e". (I am looking for a regex solution ) thanks

  • Perl vs Python: implementation of algorithms to deal with advanced data structures

    - by user350571
    I'm learning perl and everytime I search for perl stuff in the internet I get some random page with people saying that perl should die because code written in it looks like a lesson in steganography. Then they say that python is clean and stuff like that. Now, I know that those comparisons are always stupid and made by fellows that feel that languages are a extension of their boring personality so, let me ask instead: can you give me the implementation of a widely known algorithm to deal with a data structure like red-black trees in both languages so I can compare?

  • Have problems designing input and output for a calculator app

    - by zoul
    Hello! I am writing a button calculator. I have the code split into model, view and a controller. The model knows nothing about formatting, it is only concerned with numbers. All formatting is done in the view. The model gets its input as keypresses, each keypress is a part of an enum: typedef enum { kButtonUnknown = 0, kButtonMemoryClear = 100, kButtonMemoryPlus = 112, kButtonMemoryMinus = 109, kButtonMemoryRecall = 114, kButtonClear = 99, … }; When the user presses a button (say 1), the model receives a button code (kButtonNum1), adds the corresponding number to a string input buffer ("1") and updates the numeric output value (1.0). The controller then passes the numeric output value to the view that formats it (1). This is all plain, simple and clean, but does not really work. The problem is that when user enters a part of a number (say 0.00, going to enter 0.001), the input does not survive the way through model to view and the display says 0 instead of 0.00. I know why this happens ("0.00"::string parses to 0::double and that gets formatted as 0). What I don’t know is how to design the calculator so that the code stays clean and simple and the numbers will show up on screen exactly as the user types them. I’ve already come with some kind of solution, but that’s essentially a hack and breaks the beautiful and simple flow from the calculator model to the display. Ideas? Current solution keeps track of the calculator state. If the calculator is building a number, I take the calculator input buffer (a string) and directly set the display contents (also a string). Otherwise I take the proper path, ie. take the numeric calculator output, pass it to the view as a double and the view uses its internal formatter to create a string for the display. Example input: input | display | mode ------+---------+------------ 0 | 0 | from string 0. | 0. | from string 0.0 | 0.0 | from string 0.0+ | 0 | from number This is ugly. (1) The calculator has to expose its input buffer and state. (2) The view has to expose its display and allow setting its contents directly using a string. (3) I have to duplicate some of the formatting code to format the string I got from the calculator input buffer. If user enters 12345.000, I have to display 12,345.000 and therefore I’ve got to have a commification code for strings. Yuck.

  • parsing a string based on specified identifiers

    - by jml
    Let's say that I have the following text: input = "one aaa and bbb two bbbb er ... // three cccc" I would like to parse this into a group of variables that contain criteria = ["one", "two", "three"] v1,v2,v3 = input.split(criteria) I know that the example above won't work, but is there some utility in python that would allow me to use this sort of approach? I know what the identifiers will be in advance, so I would think that there has got to be a way to do this... Thanks for any help, jml
