Android: Send arbitrary objects within Activities?

- by Sebastian

I have read some question here but I didn't find a solution. I have read about Parcelable, Intents, and sharing specific data within Activities from the android dev docs (both dev guide and reference). Here's the scenario: I have one ListActivity that fills in an object parsing an xml file, it shows a list of values, and when clicked I want to return the object that represents the item clicked to the activity that has called it, for then, call another activity with this object. I read on how to implement Parcelable but seems not being the way. Implementing Parcelable receives a Parcel for the constructor and then reads the values from it (or at least that was what I understood). This makes no sense for me and I can't see how to implement basing on that issue. I build the object parsing the xml file, not having a Parcel. I appreciate some clarifications on this, regards.

Launching browser within CherryPy

- by Alan Harris-Reid

I have a html page displayed using... cherrypy.quickstart(ShowHTML(htmlfile), config=configfile) Once the page is loaded (eg. initiated via. the command 'python mypage.py'), I would like to automatically launch the browser to display the page (eg. via. http://localhost/8000). Is there any way I can achieve this (eg. via. a hook within CherryPy), or do I have to call-up the browser manually (eg. by double-clicking an icon)? TIA Alan

jQuery sortable drop within itself.

- by Janis Peisenieks

So my question here is: Can I place a sortable element within another sortable element of the same level. Example: <ul class="sortable"> <li class="subsortable">Some text</li> <li class="subsortable">Some text</li> </ul> into: <ul class="sortable"> <li class="subsortable">Some text<li class="subsortable">Some text</li></li> </ul> I've been trying to do this for a day now, and I can't seem to find a way to do this.

Running The JVM From Within An MXML Component

- by Joshua

Thinking outside of the box here... What possible basic approaches could be taken in an effort to create a Flex component that could run Java? I know I can easily use flex to browse to or launch a Java app, but there are things I can only do if I can run the Java from WITHIN an MXML Component. I the strictest sense, I know it's not impossible (ie: if you had all the source code for flex and for the jvm), but what's the least impractical means to this end? Showcase your creativity.

how have defined connection within function for pdo communication with DB

- by Scarface

hey guys I just started trying to convert my query structure to PDO and I have come across a weird problem. When I call a pdo query connection within a function and the connection is included outside the function, the connection becomes undefined. Anyone know what I am doing wrong here? I was just playing with it, my example is below. include("includes/connection.php"); function query(){ $user='user'; $id='100'; $sql = 'SELECT * FROM users'; $stmt = $conn->prepare($sql); $result=$stmt->execute(array($user, $id)); echo $count=$stmt->rowCount(); if (!$result || $stmt->rowCount()>=1){ echo 'balls'; } // now iterate over the result as if we obtained // the $stmt in a call to PDO::query() while($r = $stmt->fetch(PDO::FETCH_ASSOC)) { echo "$r[username] $r[id] \n"; } } query();

Navigation Within TabController

- by David.Chu.ca

I am trying to use UITabController as may controller in my main window and add navigation controllers to some tab bar items. For example, the first tab has a navigation controller with table view: ![alt text][1] The SettingsViewController is associated with its own NIB file, where a table view is defined. Within that xib file, I have a table view and set it to the outlet of SettingsViewController class property myTableView. The problem is that in the main xib file, for the SettingsViewController navigation, there is one outlet myTableView. I am not sure if I have to set this to somewhere? The exception I get is "[UIViewController _loadViewFromNibNamed:bundle:] loaded the "SettingsViewController" nib but the view outlet was not set." [1]:

Add links to specific words within span tag in PHP

- by dazhall

I have a list of words that I'd like to add a link to, I can do this fairly easily using preg_match_all and preg_replace: $str = "<span class=\"cz\">Dám si jedno pivo prosím.</span> = I'll have a beer please."; preg_match_all('/[a-ztúuýžácdéeínórš]+/i',$str,$matches); $matches = array_unique($matches[0]); foreach ($matches as $match) { if(!empty($words[$match])) { $str = preg_replace("/(^|[^\w]){1}(".preg_quote($match,"/").")($|[^\w]){1}/i", '\\1<a href="#">\\2</a>\\3', $str); } } echo $str; What I'd like to do is restrict the linking to only within the span tag. My brain is all regex-ed out, so any help would be appreciated! Thanks! Darren.

xquery expression to return a link text only if it contains within it a specific string

- by Arvind

I want to extract some links from a XML document (links are in same format as on html pages). Now for eg a link is "http://xyz.com/start/tyu/a.html" and another is "http://ert.com/tyu/b.html" while a third link is "http://asdf.com/ghjk/c.html" From the above 3 links (which I have with me using a for clause in a FLWOR expression)...I want only the links which contain within them a string "tyu" to be selected-- I thought of using substring for this, but substring requires start and end positions to be specified- whereas in my scenario, I dont know at which position the desired string will be. How do I do substring matching in such a scenario, i.e. where exact position for occurrence of substring, is not known? I can use XQuery 1.0 for this purpose. Finally, I want to extract the link URL, as well as link text...

How to sum properties of the objects within an array in Ruby

- by Ernst Fitschen

I understand that in order to sum array elements in Ruby one can use the inject method, i.e. array = [1,2,3,4,5]; puts array.inject(0, &:+) But how do I sum the properties of objects within an object array e.g. There's an array of objects and each object has a property "cash" for example. So I want to sum their cash balances into one total. Something like... array.cash.inject(0, &:+) (but this doesn't work) I realise I could probably make a new array composed only of the property cash and sum this, but I'm looking for a cleaner method if possible!

Open Safari from within Opera Mini on the iPhone

- by Ican Zilb

Now that Opera Mini is becoming so popular in the App store I want to effectively warn my web site visitors that the rendition they see in Opera Mini is far from what I meant them to see and redirect them to my page in Mobile Safari, so they can enjoy HTML5 and CSS3. I've been banging my head around that task all day long, but I can't seem to find a solution. My hope lies in the custom URL schemes, but seems Opera Mini handles all schemes which usually Safari does. Would be great if there's a scheme like safari://www.domain.com which opens ONLY in Safari, so I can redirect the visitors to it. Does anybody know a solution to that problem? --edit Just to make myself clear - browser detection is not the problem (I'm doing Javascript for 13 years now) the question is if there's a way to invoke the Safari app on the iPhone from within a web page which is being viewed in Opera Mini.

Multiple Payment options within the same order

- by Rob Y

I have a requirement to be able to accept different forms of payment within the same order - ie not just the usual credit card or paypal for the whole thing, but perhaps paypal for one item, cheque for another. I know this sounds quite crazy, but there is a good business reason for the requirement so I can't just push back. The best way I can think of implementing it at the moment is to have kind of a hub page, where you can "launch off" into multiple flows for each of the payments by opening new windows. I can't figure out a way of doing this in a linear flow as for example you can't guarantee that a user will come back from paypal, so you'd then lose the user completely. Is there a neater way of doing this that anyone can think of, or can anyone point me to an example of a site that does somethign similar for inspiration?

PresentModalViewController from within UISplitViewController: weird behavior in landscape mode

- by Krumelur

Hi, I've been using PresentModalViewController a lot and never had any issues. But when showing a modal controller from within any controller hosted by a UISplitViewController I get strange orientation bugs. In my table view (which is root controller of the UISplitView), when a cell is touched, I call: MyController oModal = new MyController(); oModal.ModalPresentationStyle = UIModalPresentationStyle.FormSheet; oModal.ModalTransitionStyle = UIModalTransitionStyle.CrossDissolve; this.PresentModalViewControll(oModal, true); If the iPad is in Portrait, all is okay. If it is in landscape however, the modal controller fades in but its orientation is incorrect. Then, after fading in has finished, it suddenly flips 90 degrees and adjusts to correct orientation. I have overriden ShouldAutoRotateToInterfaceOrientation(), so that cannot be it. Ideas? René

Checking if parsed date is within a date range

- by Brett Powell

So I am using a scripting language with c++-like syntax, and I am trying to think of the best way to check if a date is within range. The problem I am running into is that if the current day is in a new month, the check is failing. Here is what my code looks like: if(iMonth >= iStartMonth && iMonth <= iEndMonth) { if(iDay >= iStartDay && iDay <= iEndDay) { if(iYear >= iStartYear && iYear <= iEndYear) { bEnabled = true; return; When I have something like this: Start date: 3 27 2010 End Date: 4 15 2010 Current Date: 3 31 2010 The day check fails because if (iDay <= iEndDay) does not pass. The scripting language doesn't have a lot of time related functions, and I can't compare timestamps because I'm allowing users to put like "03:27:2010" and "04:15:2010" as start/end dates in a config file. I'm assuming I am just not thinking straight and missing an easy fix.

Posting within PHP and receiving only cookie

- by faya

Hello I have a question. It might be sound ridiculous, but let me explain what I want to accomplish. Right now I try to embed open source forum to by site and I want to leave forum and my site databases split. When my site users are logging in I want them also automatically be logged in to the forum system. For that I want to login within my PHP code after receiving username and password in post, but I don't know how I can get only cookies in response. I have found out that I can use curl_init(), curl_exec(), curl_close() functionality, but response from curl_exec returns whole response(page content, cookies, headers). Is there a way to receive only cookies? P.S. - If my design is totally wrong please give an advise how I can embed this functionality! I would be very thankful!

Unique elements of list within list in python

- by user2901061

We are given a list of animals in different zoos and need to find which zoos have animals that are not in any others. The animals of each zoo are separated by spaces, and each zoo is originally separated by a comma. I am currently enumerating over all of the zoos to split each animal and create lists within lists for different zoos as such: for i, zoo in enumerate(zoos): zoos[i] = zoo.split() However, I then do not know how to tell and count how many of the zoos have unique animals. I figure it is something else with enumerate and possibly sets, but cannot get it down exactly. Any help is greatly appreciated. Thanks

Using threads and event handlers within a WCF Web Service

- by user368984

While making a WCF Web Service, I came across a problem while using a method with a webbrowser control. The method starts a thread and uses a webbrowser control to fill in some forms and click further, waiting for a event handler to fire and return a answer I need. The method is tested and works within its own enviroment, but used in a WCF Web Service enviroment, the event handlers just won't fire. A result of that is the waiting manualresetevent not ending. Is this because of the new thread or because of the bad event handling of the web service? If yes, what is a reasonable solution?

regex not working "within" javascript string

- by Tim

I'm trying to replace all mentions of [b] in a text string and replace it with <b>. The problem with what I'm using below this that it's replace every [b] on the page, and I only want it to change the [b]'s within the text string ("text") that I'm sending in. Taking out the 'g' for global in the regex doesn't work very well because it then doesn't replace them all... text = text.replace(new RegExp('(^|\\s|>)\\[b](\\S.*?\\S)\\[/b]($|\\s|<)', 'gim') , '$1<strong>$2</strong>$3'); any ideas? Thanks

C++ Structure within itself?

- by Douglas

I've been trying to port this code to python, but there is something I do not quite understand in C++ (I do know a bit of C++ but this is beyond me): typedef struct huffnode_s { struct huffnode_s *zero; struct huffnode_s *one; unsigned char val; float freq; } huffnode_t; What I don't get is how huffnode_s can be within itself, I've never seen this before and don't quite understand it. What does this mean, and if someone can, what would be the python equivalent?

Filter objects within two seconds of one another using SQLAlchemy

- by Arrieta

Hello: I have two tables with a column 'date'. One holds (name, date) and the other holds (date, p1, p2). Given a name, I want to use the date in table 1 to query p1 and p2 from table two; the match should happen if date in table one is within two seconds of date in table two. How can you accomplish this using SQLAlchemy? I've tried (unsuccessfully) to use the between operator and with a clause like: td = datetime.timedelta(seconds=2) q = session.query(table1, table2).filter(table1.name=='my_name').\ filter(between(table1.date, table2.date - td, table2.date + td)) Any thoughts?

Replace existing XML file within iPhone app

- by Chonch

Hey, I have an .xml file that is going to be shipped within my app. This file contains values that are read from it and saved as an array when the app launches. Each time the app is run, I want to check with the server if there is an internet connection. If so, I want to get the newest version of the .xml file from the server and replace the one that I currently have saved in my app (this way, the next time the user logs in and doesn't have internet access, he/she will be able to use the old (yet most up to date) data). What is the best way to do this? Thanks,
