  • How do I correctly decode unicode parameters passed to a servlet

    - by Grant Wagner
    Suppose I have: <a href="http://www.yahoo.com/" target="_yahoo" title="Yahoo!&#8482;" onclick="return gateway(this);">Yahoo!</a> <script type="text/javascript"> function gateway(lnk) { window.open(SERVLET + '?external_link=' + encodeURIComponent(lnk.href) + '&external_target=' + encodeURIComponent(lnk.target) + '&external_title=' + encodeURIComponent(lnk.title)); return false; } </script> I have confirmed external_title gets encoded as Yahoo!%E2%84%A2 and passed to SERVLET. If in SERVLET I do: Writer writer = response.getWriter(); writer.write(request.getParameter("external_title")); I get Yahoo!â„¢ in the browser. If I manually switch the browser character encoding to UTF-8, it changes to Yahoo!TM (which is what I want). So I figured the encoding I was sending to the browser was wrong (it was Content-type: text/html; charset=ISO-8859-1). I changed SERVLET to: response.setContentType("text/html; charset=utf-8"); Writer writer = response.getWriter(); writer.write(request.getParameter("external_title")); Now the browser character encoding is UTF-8, but it outputs Yahoo!â?¢ and I can't get the browser to render the correct character at all. My question is: is there some combination of Content-type and/or new String(request.getParameter("external_title").getBytes(), "UTF-8"); and/or something else that will result in Yahoo!TM appearing in the SERVLET output?

  • How to remove code from HTML string?

    - by TruMan1
    I have a variable that has this string: <DIV><SPAN style="FONT-FAMILY: Tahoma; FONT-SIZE: 10pt">[If the confirmation is active the subscriber will receive this email after succesfully confirming. If not, this will be the first and only email he will receive.]</SPAN></DIV> <p align=center> <input class=fieldbox10 type = 'button' name = 'button' value = 'Close' onclick = "window.close()"> </p> How do I remove the below string without worrying about spaces via Javascript (or jQuery)? <p align=center> <input class=fieldbox10 type = 'button' name = 'button' value = 'Close' onclick = "window.close()"> </p>

  • Keyboard focus being stolen by Flash

    - by NewUser
    Performing a search, I noticed several questions dedicated to how to steal/trap the keyboard focus of the visitor. Considering this site is dedicated to programming that's not suprising. I was wondering if anyone can advise me on how to prevent this type of behavior. Losing keyboard focus to flash basically removes my browser's functionality until I use the mouse to click elsewhere (I use Mozilla Firefox). Anyone know of some kind of plugin or greasemonkey script that will prevent my keyboard focus from being stolen? Normal browser "shortcuts" are rendered useless by having to use the mouse to return keyboard focus to the browser. Edit: Reply to the post below, I do have flashblock / noscript and some other things. My issue is flash that I want to see/interact with stealing my focus. Basically looking for something I can toggle that will prevent flash from getting keyboard focus or a way to force my firefox keyboard commands to the browser

  • Why aren't my objects sorting with sortedArrayUsingDescriptors?

    - by clozach
    I expected the code below to return the objects in imageSet as a sorted array. Instead, there's no difference in the ordering before and after. NSSortDescriptor *descriptor = [[NSSortDescriptor alloc] initWithKey:@"imageID" ascending:YES]; NSSet *imageSet = collection.images; for (CBImage *image in imageSet) { NSLog(@"imageID in Set: %@",image.imageID); } NSArray *imageArray = [[imageSet allObjects] sortedArrayUsingDescriptors:(descriptor, nil)]; [descriptor release]; for (CBImage *image in imageArray) { NSLog(@"imageID in Array: %@",image.imageID); } Fwiw, CBImage is defined in my core data model. I don't know why sorting on managed objects would work any differently than on "regular" objects, but maybe it matters. As proof that @"imageID" should work as the key for the descriptor, here's what the two log loops above output for one of the sets I'm iterating through: 2010-05-05 00:49:52.876 Cover Browser[38678:207] imageID in Array: 360339 2010-05-05 00:49:52.876 Cover Browser[38678:207] imageID in Array: 360337 2010-05-05 00:49:52.877 Cover Browser[38678:207] imageID in Array: 360338 2010-05-05 00:49:52.878 Cover Browser[38678:207] imageID in Array: 360336 2010-05-05 00:49:52.879 Cover Browser[38678:207] imageID in Array: 360335 ... For extra credit, I'd love to get a general solution to troubleshooting NSSortDescriptor troubles (esp. if it also applies to troubleshooting NSPredicate). The functionality of these things seems totally opaque to me and consequently debugging takes forever.

  • Sanity check on this idea for an Image Viewer in a web app

    - by Charlie Flowers
    I have an approach in mind for an image viewer in a web app, and want to get a sanity check and any thoughts you stackoverflowers might have. Here's the whirlwind nutshell summary: I'm working on an ASP.NET MVC application that will run in my company's retail stores. Even though it is a web application, we own the store machines and have control over them. We have a "windows agent" running on the store machine which we can talk to via http post (it is a WCF service, and our web app has permission to talk to it from the browser). One of the web pages needs to be an "image viewer" page with some common things like Rotate & Zoom. Now, there are some WebForms controls that offer Rotate and Zoom. However, they take up server resources and generate a good bit of traffic between the server and the browser. For example, the Rotate function would cause an ajax call to the server, which would then generate a new image written to a .NET Canvas object, which would then be written to a file on the server, which would then be returned from the ajax call and refreshed inside the browser. Normally, that's a pretty good way of doing things. But in our case, we have code running on the store machine that we can communicate with. This leads me to consider the following approach: When the user asks to view an image, we tell our "windows agent" to download it from our image server to the store machine. We then redirect our browser to our image viewer page, which will pull the image from the local file we just wrote to the store machine. When the user clicks "Rotate", we cause JavaScript code in the browser to call our "windows agent" software, asking it to perform the "Rotate" function. The "windows agent" does the rotation using the same kind of imaging control that would formerly have been used on the server, but it does so now on the store machine. Javascript in the browser then refreshes the image on the page to show the newly rotated image. Zoom and similar features would be implemented the same way. This seems to be much more efficient, scalable, and responsive for the end-users. However, I've never heard of anything like it being done, mostly because it's rare to have this combination of a web app plus a "windows agent" on the client machine. What do you think? Feasible? Reasonable? Any pitfalls I overlooked or improvements / suggestions you can see? Has anyone done anything like this who would like to offer the wisdom of experience? Thanks!

  • Slide down and slide up div on click

    - by 422
    I am using the following code to open and close a div ( slide up/down ) using js I have the slide down event attached to a button and the slide up event sttached to close text. What I want is the button onclick to open and onclick again close the slide element. Here is the JS // slide down effect $(function(){ $('.grabPromo').click(function(){ var parent = $(this).parents('.promo'); $(parent).find('.slideDown').slideDown(); }); $('.closeSlide').click(function(){ var parent = $(this).parents('.promo'); $(parent).find('.slideDown').slideUp(); }); }); The HTML: <span class="grabPromo">Open</span> and in the slide down area i have <a class="closeSlide">Close</a> Any help appreciated. Ideally I want a down pointing arrow on the slide down button and a up pointing arrow to replace it to slide up on same button. And do away with the close link altogether. Any help appreciated. Cheers

  • How can I distinguish between overlapping segments of text using HTML?

    - by Siracuse
    Easy question, it is valid to have overlapping spans in html? Example: <span id="1">This is <span id="2"> some text </span> some other text </span> ^ ^ End1 End2 Edit: I see now that the spans closing tag would be ambiguous about which one it is closing, and that first </span> would close span id = 2, not 1 like I intended. My problem is, I have a block of text which I'm trying to highlight based on what the mouse hovers over. This block of text is composed of sections, some of which "overlap" eachother. I'm trying to use some jQuery and HTML to present this document so when I hover over the sections, the appropriate one will be highlighted. So, in my example above, the first span is meant to be ended with the first span close tag, and the second span is meant to be ended to with the second span close tag. This is because of the semantics of my document, these are two overlapping segments. I want it so when I hover to the left, it will only highlight up to span id = 1 and the first span close, if I hover between the two "overlapping" spans, it will highlight both of them, and if I hover to the right, it will highlight from span id=2 to the last span close. However, I'm starting to think this isn't possible. Is there any way I can distinguish segments of text in HTML that allows overlapping? So my jQuery script that highlights when I hover over different spans will highlight the correct portions. Should I alternate between div's and spans? Would that disambiguate what I'm closing then and allow me the do the proper highlighting with my jQuery hover script? I'm wondering about more than 2 segments overlapping now. Sigh, I wish I could just be explicate about what I'm closing.

  • Show javascript execution progress

    - by Midhat
    I have some javascript functions that take about 1 to 3 seconds. (some loops or mooML templating code.) During this time, the browser is just frozen. I tried showing a "loading" animation (gif image) before starting the operation and hiding it afterwords. but it just doesnt work. The browser freezes before it could render the image and hides it immediately when the function ends. Is there anything I can do to tell the browser to update the screen before going into javascript execution., Something like Application.DoEvents or background worker threads. So any comments/suggestions about how to show javascript execution progress. My primary target browser is IE6, but should also work on all latest browsers

    Dear all, I write a program to execute and send msg using windows net send command.Its working fine for single receptor.But the problem happen when i want to send message in many receptors. i use a for loop to take receptor name from a list box. Here all message go to the first receptor.The problem happen on process execution.So far i guess the process is not clear or dead on the time. Can any body guide me how i can send the msg to multiple users at a time? my code below: string sendingMessage = messageRichTextBox.Text; string[] recepentAddressArray = new string[recepentAddressListBox.Items.Count]; for (int j = 0; j < recepentAddressListBox.Items.Count; j++) // Getting address from list box { recepentAddressArray[j] = recepentAddressListBox.Items[j].ToString(); string recepantAddress = recepentAddressArray[j]; try { string strLine = "net send " + recepantAddress + " " + sendingMessage + " >C:netsend.log"; FileStream fs = new FileStream("c:netsend.bat", FileMode.Create, FileAccess.Write); StreamWriter streamWriter = new StreamWriter(fs); streamWriter.BaseStream.Seek(0, SeekOrigin.End); streamWriter.Write(strLine); streamWriter.Flush(); streamWriter.Close(); fs.Close(); Process p = new Process(); p.StartInfo.FileName = "C:netsend.bat"; p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden; p.Start(); p.WaitForExit(); p.Close(); FileStream fsOutput = new FileStream("C:netsend.log", FileMode.Open, FileAccess.Read); StreamReader reader = new StreamReader(fsOutput); reader.BaseStream.Seek(0, SeekOrigin.Begin); string strOut = reader.ReadLine(); reader.Close(); fsOutput.Close(); } catch (Exception) { MessageBox.Show("ERROR"); } }

  • Working with multiple input and output files in Python

    - by Morlock
    I need to open multiple files (2 input and 2 output files), do complex manipulations on the lines from input files and then append results at the end of 2 output files. I am currently using the following approach: in_1 = open(input_1) in_2 = open(input_2) out_1 = open(output_1, "w") out_2 = open(output_2, "w") # Read one line from each 'in_' file # Do many operations on the DNA sequences included in the input files # Append one line to each 'out_' file in_1.close() in_2.close() out_1.close() out_2.close() The files are huge (each potentially approaching 1Go, that is why I am reading through these input files one at a time. I am guessing that this is not a very Pythonic way to do things. :) Would using the following form good? with open("file1") as f1: with open("file2") as f2: # etc. If yes, could I do it while avoiding the highly indented code that would result? Thanks for the insights!

  • Nullpointerexcption & abrupt IOStream closure with inheritence and subclasses

    - by user1401652
    A brief background before so we can communicate on the same wave length. I've had about 8-10 university courses on programming from data structure, to one on all languages, to specific ones such as java & c++. I'm a bit rusty because i usually take 2-3 month breaks from coding. This is a personal project that I started thinking of two years back. Okay down to the details, and a specific question, I'm having problems with my mutator functions. It seems to be that I am trying to access a private variable incorrectly. The question is, am I nesting my classes too much and trying to mutate a base class variable the incorrect way. If so point me in the way of the correct literature, or confirm this is my problem so I can restudy this information. Thanks package GroceryReceiptProgram; import java.io.*; import java.util.Vector; public class Date { private int hour, minute, day, month, year; Date() { try { BufferedReader keyboard = new BufferedReader(new InputStreamReader(System.in)); System.out.println("What's the hour?

  • Using Javascript in Adobe Reader

    - by godleuf
    Hi, I am currently using the following script for a few documents: var pp = this.getPrintParams(); pp.interactive = pp.constants.interactionLevel.automatic; this.print(pp); How do I add another command, say document.close() so that it reads the print function and then follows the close document last? Do I simply add the close command right after the print command so it would read var pp = this.getPrintParams(); pp.interactive = pp.constants.interactionLevel.automatic; this.print(pp); document.close(); Thanks.

  • Load page, wait, log any JavaScript errors to file?

    - by David
    I would like to check a large number of HTML files with inline JavaScript for JavaScript errors. What I'm envisioning doing is this: Script a browser to load a given page, wait a few seconds, and finally check the browser logs. I'm unsure though both on how to script a browser to load a given page and on how to access the JavaScript error log. I think the type of errors I'm worried about should show up in any modern browser so I would just go with whatever makes it most convenient. I'd be working either under Mac OS X or Linux. Anybody already tackle a similar problem? I've thought a bit about hacking something together based on a unit testing framework -- generate a trivial (assertTrue(true)) test for each page and rely on the errors making it fail -- but I'm hoping for something more elegant. Thank you.

  • Why is this not a bug in qmail?

    - by jemfinch
    I was reading DJB's "Some thoughts on security after ten years of Qmail 1.0" and he listed this function for moving a file descriptor: int fd_move(to,from) int to; int from; { if (to == from) return 0; if (fd_copy(to,from) == -1) return -1; close(from); return 0; } It occurred to me that this code does not check the return value of close, so I read the man page for close(2), and it seems it can fail with EINTR, in which case the appropriate behavior would seem to be to call close again with the same argument. Since this code was written by someone with far more experience than I in both C and UNIX, and additionally has stood unchanged in qmail for over a decade, I assume there must be some nuance that I'm missing that makes this code correct. Can anyone explain that nuance to me?

  • killing all instances of chrome on the command line?

    - by Fedor
    In some cases killing a single tab/process doesn't do it and I need to close Chrome entirely. Since Chrome has multiple processes, how can I close all of them at once? I know that... pgrep chrome returns all the pids, can someone tell me a trick that would allow me to close all of them by feeding them to another command or merging them to a csv or something?

  • What is wrong with this null check for data reader

    - by Phil
    c.Open() r = x.ExecuteReader If Not r("filename").IsDbnull Then imagepath = "<img src='images/'" & getimage(r("filename")) & " border='0' align='absmiddle'" End If c.Close() r.Close() I have also tried; If r("filename") Is DBNull.Value Then imagepath = String.Empty Else imagepath = "<img src='images/'" & getimage(r("filename")) & " border='0' align='absmiddle'" End If c.Close() r.Close() The error is: Invalid attempt to read when no data is present. The idea of my code is to build an img src string only when data is available. Help greatly appreciated. Thanks

  • Manually closing a port from commandline

    - by codingfreak
    Hi I want to close an open port which is in listening mode between my client and server application. Is there any manual command line option in Linux to close a port ?? NOTE: I came to know that "only the application which owns the connected socket should close it, which will happen when the application terminates." I dont understand why it is only possible by the application which opens it ... But still eager to know if there is any another way to do it ??
