[Android] How do I load URL that requires login into variable?

- by bebeTech

I am trying to port my usage meter from a JavaScript Gadget (win) / Widget (OSX) to Android. Total newbie when comes to JAVA + Eclipse + Android 2.1 SDK. Essentially what I want to do is load a page, pass through a username and password and load the resulting page into a array that I can then run some regular expressions through. My code from JavaScript (I've replace the actual URL with a dummy one) is: xmlhttp.open("post","https://acme.com.au/your_account/index.php?function=login",false); xmlhttp.setRequestHeader("If-Modified-Since", "Sat, 1 Jan 2000 00:00:00 GMT"); xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded"); xmlhttp.send("check_username=" + username + "&password=" + password); I need to know the Android equivalent to the above please. I've played around with WebView but that loads the page in a web browser which isn't what I want.

regex: trim all strings directly preceeded by digit except if string belongs to predefined set of st

- by Geert-Jan

I've got addresses I need to clean up for matching purposes. Part of the process is trimming unwanted suffices from housenumbers, e.g: mainstreet 4a --> mainstreet 4. However I don't want: 618 5th Ave SW --> 618 5 Ave SW in other words there are some strings (for now: st, nd, rd, th) which I don't want to strip. What would be the best method of doing this (regex or otherwise) ? a wokring regex without the exceptions would be: a = a.replaceAll("(^| )([0-9]+)[a-z]+($| )","$1$2$3"); //replace 1a --> 1 I thought about first searching and substiting the special cases with special characters while keeping the references in a map, then do the above regex, and then doing the reverse substitute using the reference map, but I'm looking for a simpler solution. Thanks

How can I ensure that JavaScript inserted via AJAX will be executed after the accompanying HTML (als

- by RenderIn

I've got portions of pages being replaced with HTML retrieved via AJAX calls. Some of the HTML coming back has JavaScript that needs to be run once in order to initialize the accompanying HTML (setting up event handlers). Since the document has already been loaded, when I replace chunks of HTML using jQuery's .html function, having jQuery(document).ready(function() {...}); doesn't execute since the page loaded long before and this is just a snippet of HTML being replaced. What's the best way to attach event handlers whose code is packaged along with the HTML it's interested in, when that content is loaded via AJAX? Should I just put a procedural block of javascript after the HTML , so that when I insert the new HTML block, jQuery will execute the javascript immediately? Is the HTML definitely in the DOM and ready to be acted upon by JavaScript which is in the same .html call?

PHP Possible Memory Leak

- by dropson

I have a script that loops through a database for images to convert with gd & imagick. I unset or replace all variables and objects in between each loop. For each loop, get_memory_usage(1) reveals a concurrent amount of memory used by that script. Which is expected. But, when I run "top", the %MEM column reports that this script, (same PID), increments with several percentages for each loop. I destroy all images when I'm done with them, and when I run get_defined_vars(); only the standard globals and a few variables I have is set. Why is "top" % Memory Usage different than what PHP reports? After 10 loops, PHP has taken 20% percetage of the system memory. I run php 5.2.6 on Debian 5

Check if a string substitution rule will ever generate another string.

- by Mgccl

Given two strings S and T of same length. Given a set of replacement rules, that find substring A in S and replace it with string B. A and B have the same length. Is there a sequence of rule application, such that it make string S into string T? I believe there is no better way to answer this than try every single rule in every single state. Which would be exponential time. But I don't know if there are better solutions to it.

Android: Is decreasing size of .png files have some effect to resulted Bitmap in memory

- by nahab

I'm writing game with a large amount of .png pictures. All worked fine. Than I added new activity with WebView and got memory shortage. After that I made some experiment - replace game .png images with ones that just fully filled with some color. As result memory shortage had gone. But I suppose that Bitmap internally hold each pixel separately so such changes should have no effect. Maybe this because of initial images have alpha channel and my test images have not it? But actually question is: Will decreasing .png images files sizes make some effect on decreasing usage of VM application heap or not?

JQuery overlay - issues with opening twitter "Allow Access" box

- by Gublooo

Hey guys I'm using Jquery flowplayer tools overlay to open external links. External links are working fine with this piece of code shown in the link: http://www.demiseonline.com/misc/Iframeoverlay.html Now using this overlay - I wanted to open the twitter dialog which asks users to Allow access to their account. So in the code below, I replaced http://www.google.com with https://twitter.com/oauth/authenticate?oauth_token=VPVRIsnRz9IX4CAab7brert3jHiEs <div class="apple_overlay black" id="Overlay1" <iframe src ="http://www.google.com" width="100%" height="595px" frameborder="0" </iframe </div When I replace the code, as soon as I load the page, even before I click on the link to open the overlay - the page gets redirected to the twitter URL. Any idea why that happens for this URL. Thanks

Gaining application/module context from a symfony task

- by Martin Chatterton

I have written a reporting suite, and I have a specific report that builds a CSV file. Serving this file via a browser on demand isn't an issue, but I need to be able to build this CSV file nightly, and email round a link to be able to download it. Essentially, I need to be able to replace a specific action with a symfony task, run via cron. So how do I gain application/module context from a symfony task? And secondly, how would I invoke the SwiftMailer library from a symfony task? I'm using symfony v1.4.4 and PHP v.5.2.13. Thanks in advance for your help.

O(log N) == O(1) - Why not?

- by phoku

Whenever I consider algorithms/data structures I tend to replace the log(N) parts by constants. Oh, I know log(N) diverges - but does it matter in real world applications? log(infinity) < 100 for all practical purposes. I am really curious for real world examples where this doesn't hold. To clarify: I understand O(f(N)) I am curious about real world examples where the asymptotic behaviour matters more than the constants of the actual performance. If log(N) can be replaced by a constant it still can be replaced by a constant in O( N log N). This question is for the sake of (a) entertainment and (b) to gather arguments to use if I run (again) into a controversy about the performance of a design.

Suppress checking for changes on file system in Eclipse RCP

- by panschk

Okay, I guess this question is too difficult, but it's worth a try. I have an eclipse RCP application that edits HTML-files. I deal with the content of the files only in a W3C-Dom representation. There is some stuff that I can not do with that, so I the program edits each file each time after it is saved (save, save as). Of course, the file is then out of synch with the file system, and the next time I touch it, eclipse complains: "The file has been changed on the file system. Do you want to replace the editor contents with these changes? (Yes/No)" I do not want to load the changes into the editor ("No") Maybe there is a way to tell Eclipse programmatically to not check that file for changes, or to configure it to not check for changes on any file? edit: Everything has to be done either programatically or by editing some XML files. I can not expect the user to do anything;-)

jquery textarea custom tags replacement

- by Tim

Hi all, I'm basically trying to create my own tags - and replace them with the right HTML tags. So {B} {/B} would turn into <b> </b> I have only got so far with this, here: http://www.nacremedia.com/text2.htm Use the [B] button to bold stuff the current selection... it creates two bold tags and one closing for some reason. I'm so close! But I just need a bit of direction to get the final bugs out - can anyone please help?? Also, if there is a better way of doing this altogether then I am more than welcome to new ideas.

Accented character replacement for search then reinserted afterwards

- by user314573

Basically my issue is that users would like to search for a french word that has accented characters but without typing in the accented characters and then have the actual accented word appeared highlighted if found... So for example they would type in "declare" but in the result sets it would look like "déclare" and if found "déclare" would be highlighted. My first thought was to just simply replace the characters with a regex but then I remembered that I would need to re-insert the replaced characters after the search... I was thinking of then using some sort of character map that would track position and the character so that when the search was finshed I could put the result set back to the way it was. This seems a little brute force to me and I was wondering if anyone had a better alternative? I'm using Visual Studio 2005 with this app. Any advice would be much appreciated! Thanks

Given a word, how do I get the list of all words, that differ by one letter?

- by user187809

Let's say I have the word "CAT". These words differ from "CAT" by one letter (not the full list) CUT CAP PAT FAT COT etc. Is there an elegant way to generate this? Obviously, one way to do it is through brute force. pseduo code: while (0 to length of word) while (A to Z) replace one letter at a time, and check if the resulting word is a valid word If I had a 10 letter word, the loop would run 26 * 10 = 260 times. Is there a better, elegant way to do this?

how to assign to the names() attribute of the value of a variable in R

- by Tony

In R, "assign('x',v)" sets the object whose name is 'x' to v. Replace 'x' by the result of applying a text function to a variable x. Then "assign" shows its worth. Unfortunately, "assign(paste('names(','x',')',sep=''),v)" fails. So if 'x' is a variable x, I can set its value, but I can't give it names for its elements. Can one work around this? a parse-eval trick maybe? Thanks.

Is it possible to use JavaScript to break the HTML of a page?

- by Karl Brown

I've been asked at work whether it is possible to write, on purpose or by accident, JavaScript that will remove specific characters from a HTML document and thus break the HTML. An example would be adding some JavaScript that removes the < symbol in the page. I've tried searching online and I know JavaScript can replace strings, but my knowledge of the language is negligible. I've been asked to look into it as a way of hopefully addressing why a site I work on needs to have controls over who can add bespoke functionality to the page. I'm hoping it's not possible but would be grateful for the peace of mind!

insert VBS variable within a single-quoted WMI query

I have tried chr(34) and it didn't work. Please help if possible. Much appreciated!

JQuery UI Tabs + Wordpress issues

Hello dear Stackoverflow gurus, I am trying to integrate JQuery tabs with my WordPress blog, to replace old HTML Navigation menu. I am half way there but not quiet... Take a look for yourself: http://www.isahat.com The template breaks right away since the first button of the Tab menu is linked to index.php like so: Home Info The second tab menu shows my Info page just fine, but on top of everything else. My home page and everything else gets shifted down to make room for Info page. And why after clicking on any article or even the tab link, my tab menu disappears and all my navigation links turn into a bullet list? Thank you, Sahat.

XSLT: How to get XML

I have a XSL that transforms one format of XML into another. In input XML I have a node with following value - which is actually a XML string if we replace < with < (less than) for e.g. <Paragraph><Title><!CDATA[Pour les nuits du 2012-10-01 - 2012-10-30]]></Title><Text><![CDATA[TAXES INCLUSES.]]></Text></Paragraph> I want to have the content of otherInfo as a XML node in output XML. if I do , I do not get it as a XML node - it is output just as text. How can I make XSL output the content of otherInfo as XML node ?

A null value should be considered as 0 when addition of it is done with decimal value.

- by Harikrishna

There are three column in the datatable A,B and C. Now each column is type of decimal. Now I am doing like dt.Columns["A"].Expression="B+C"; to make addition of Column B's record and column C's record. Now if there is any value of B or C is null then addition of B and C will be null like B's value is 3 and C's value is null for first row then B+C(3+null) will be null which is not appropriate, the result of addition should be 3.If I replace 0 instead of null then it will be ok.But whereever there is null value in the records it should be remain it is and it should not be replaced by 0.That is null value should not be replaced by 0 and when addition of null value is done with any decimal value null value should be considered as 0. Is it possible,how can we do this ?

I don't need to validate the page, I'm no JS expert at all I'm not sure if I can replace it with &. Thanks.

Possible to fire asp.net validation from jQuery?

- by Abe Miessler

I have a form with several text boxes on it. I only want to accept floats, but it is likely that users will enter a dollar sign. I'm using the following code to remove dollar signs and validate the content: jQuery: $("#<%= tb.ClientID %>").change(function() { var ctrl = $("#<%= tb.ClientID %>"); ctrl.val(ctrl.val().replace('$','')) }); asp.net validation: <asp:CompareValidator ID="CompareValidator4" runat="server" Type="Double" ControlToValidate="tb" Operator="DataTypeCheck" ValidationGroup="vld_Page" ErrorMessage="Some error" /> My problem is that when someone enters a dollar sign in the TextBox "tb" and changes focus the validation happens first and THEN the jQuery removes the dollar sign. Is it possible to have the jQuery run first or to force the validation to run again after the jQuery executes?
