• iPod touch debugging: Error on install/run only if app exists on device already?

  - by Ben

  Hi all, I am using an iPod to test an app. The device is all set up with the right provisioning profiles, etc-- that's not really the issue. But every time I start the app from Xcode on the device, I get the "A signed resource has been added, modified, or deleted." error from the Organizer window. Wait, I know, you think it's a provisioning profile problem. But here's the kicker: if I just delete the app from the iPod (using the main screen) and try again, it works fine. I only get this error when the app is already installed. The other kicker is that this behavior doesn't happen on an iPhone that I have for occasional testing-- on that device, I can start/restart/restart indefinitely. But using the iPod, my compile-run-test cycle is annoyingly slow since I have to manually delete the app each time. Any ideas? I'm using Xcode 3.2.2 (prerelease) FWIW. The iPod has stock OS 3.1.2 on it. Thanks!

• Creating a service (SERVICE_ACCEPT_SESSIONCHANGE)

  - by Ron

  Hi there, I am trying to create a service following the example documented in the link below: http://msdn.microsoft.com/en-us/library/bb540475(v=VS.85).aspx What I am interested in is to be able to catch user "lock" and "unlock" workstation events. Using the code on from the example provided, I modified the following: Line 15: Original: VOID WINAPI SvcCtrlHandler( DWORD ); Modified: DWORD WINAPI SvcCtrlHandler( DWORD, DWORD, LPVOID, LPVOID ); Line 141: Original: gSvcStatusHandle = RegisterServiceCtrlHandler( SVCNAME, SvcCtrlHandler); Modified: gSvcStatusHandle = RegisterServiceCtrlHandlerEx( SVCNAME, SvcCtrlHandler, NULL); Line 244: Original: SvcStatus.dwControlsAccepted = SERVICE_ACCEPT_STOP; Modified: gSvcStatus.dwControlsAccepted = SERVICE_ACCEPT_STOP|SERVICE_ACCEPT_SESSIONCHANGE; Line 266: Original: VOID WINAPI SvcCtrlHandler( DWORD dwCtrl ) { // Handle the requested control code. switch(dwCtrl) { case SERVICE_CONTROL_STOP: ReportSvcStatus(SERVICE_STOP_PENDING, NO_ERROR, 0); // Signal the service to stop. SetEvent(ghSvcStopEvent); ReportSvcStatus(gSvcStatus.dwCurrentState, NO_ERROR, 0); return; case SERVICE_CONTROL_INTERROGATE: break; default: break; } }` Modified: DWORD WINAPI SvcCtrlHandler( DWORD dwControl, DWORD dwEventType, LPVOID lpEventData, LPVOID lpContext ) { DWORD dwErrorCode = NO_ERROR; switch(dwControl) { case SERVICE_CONTROL_STOP: ReportSvcStatus(SERVICE_STOP_PENDING, NO_ERROR, 0); // Signal the service to stop. SetEvent(ghSvcStopEvent); ReportSvcStatus(gSvcStatus.dwCurrentState, NO_ERROR, 0); break; case SERVICE_CONTROL_INTERROGATE: break; case SERVICE_CONTROL_SESSIONCHANGE: ReportSvcStatus(gSvcStatus.dwCurrentState, NO_ERROR, 0); break; default: break; } return dwErrorCode; } With the changes above, my service compiled and install fine. But when I try to start my service on my Windows 2000 machine, it does not start properly (it will be stuck on the "starting" status) Can anyone please advise? Thank you in advance, Ron

• Unexpected performance curve from CPython merge sort

  - by vkazanov

  I have implemented a naive merge sorting algorithm in Python. Algorithm and test code is below: import time import random import matplotlib.pyplot as plt import math from collections import deque def sort(unsorted): if len(unsorted) <= 1: return unsorted to_merge = deque(deque([elem]) for elem in unsorted) while len(to_merge) > 1: left = to_merge.popleft() right = to_merge.popleft() to_merge.append(merge(left, right)) return to_merge.pop() def merge(left, right): result = deque() while left or right: if left and right: elem = left.popleft() if left[0] > right[0] else right.popleft() elif not left and right: elem = right.popleft() elif not right and left: elem = left.popleft() result.append(elem) return result LOOP_COUNT = 100 START_N = 1 END_N = 1000 def test(fun, test_data): start = time.clock() for _ in xrange(LOOP_COUNT): fun(test_data) return time.clock() - start def run_test(): timings, elem_nums = [], [] test_data = random.sample(xrange(100000), END_N) for i in xrange(START_N, END_N): loop_test_data = test_data[:i] elapsed = test(sort, loop_test_data) timings.append(elapsed) elem_nums.append(len(loop_test_data)) print "%f s --- %d elems" % (elapsed, len(loop_test_data)) plt.plot(elem_nums, timings) plt.show() run_test() As much as I can see everything is OK and I should get a nice N*logN curve as a result. But the picture differs a bit: Things I've tried to investigate the issue: PyPy. The curve is ok. Disabled the GC using the gc module. Wrong guess. Debug output showed that it doesn't even run until the end of the test. Memory profiling using meliae - nothing special or suspicious. ` I had another implementation (a recursive one using the same merge function), it acts the similar way. The more full test cycles I create - the more "jumps" there are in the curve. So how can this behaviour be explained and - hopefully - fixed? UPD: changed lists to collections.deque UPD2: added the full test code UPD3: I use Python 2.7.1 on a Ubuntu 11.04 OS, using a quad-core 2Hz notebook. I tried to turn of most of all other processes: the number of spikes went down but at least one of them was still there.

• Passing youtube video id from video feed to flash

  - by Grant Anderson

  I'm working on a flash web application (Actionscript 2.0) for my honours project but am having trouble embedding youtube videos. Basically the user selects symbols which queries the youtube api with certain tags depending on the symbols chosenand a random video is then picked from the first 30 videos. I have this working using the following code: on (release) { url="http://gdata.youtube.com/feeds/api/videos?q=danger+passion&orderby=published&start-index="+random(30)+"&max-results=1&v=2" getURL(url); } but this just displays a webpage with a link to the youtube video. This is the code I'll be using as the foundations for the player: // create a MovieClip to load the player into var ytplayer:MovieClip = _root.createEmptyMovieClip("ytplayer", 1); // create a listener object for the MovieClipLoader to use var ytPlayerLoaderListener:Object = { onLoadInit: function() { // When the player clip first loads, we start an interval to // check for when the player is ready loadInterval = setInterval(checkPlayerLoaded, 250); } }; var loadInterval:Number; function checkPlayerLoaded():Void { // once the player is ready, we can subscribe to events, or in the case of // the chromeless player, we could load videos if (ytplayer.isPlayerLoaded()) { ytplayer.addEventListener("onStateChange", onPlayerStateChange); ytplayer.addEventListener("onError", onPlayerError); clearInterval(loadInterval); } } function onPlayerStateChange(newState:Number) { trace("New player state: "+ newState); } function onPlayerError(errorCode:Number) { trace("An error occurred: "+ errorCode); } // create a MovieClipLoader to handle the loading of the player var ytPlayerLoader:MovieClipLoader = new MovieClipLoader(); ytPlayerLoader.addListener(ytPlayerLoaderListener); // load the player ytPlayerLoader.loadClip("http://www.youtube.com/v/pv5zWaTEVkI", ytplayer); can anyone help me on how to get the id of the video (for example: pv5zWaTEVkI) from the feed? Or how to send a query from flash which will return the video url/id as opposed to the url of a feed. Any help would be much appreciated as my hand in rather soon. Thanks

• Inserting a ContentControl after another ContentControl

  - by Markus Roth

  In our VSTO Word 2010 Addin, we are trying to insert a RichTextControl after a given other ContentControl. We have tried this: public ContentControl AddContentControl(WdContentControlType type, int position) { Paragraph paragraphBefore = null; if (position == 0) { if (WordDocument.Paragraphs.Count == 0) { WordDocument.Paragraphs.Add(); } paragraphBefore = WordDocument.Paragraphs.First; } else { paragraphBefore = Controls.ElementAt(position - 1).Range.Paragraphs.Last; } object start = paragraphBefore.Range.End; object end = paragraphBefore.Range.End + 1; paragraphBefore.Range.InsertParagraphAfter(); Range rangeToUse = WordDocument.Range(ref start, ref end); ContentControl newControl = _ContentControl = _WordDocument.ContentControls.Add(type, rangeToInsert); Controls.Insert(position, newControl); OnNewContentControl(newControl, position); return newControl.ContentControl; } which works fine, unless the control that is before the one we want to insert has an empty paragraph at the end. If that is the case, the new ContentControl is inserted within the last control. How can we avoid this?

• DataReader-DataSet Hybrid solution

  - by G33kKahuna

  My solution architects and I have exhausted both pure Dataset and Datareader solutions. Basically we have a Microsoft.NET 2.0 windows service application that pulls data based on a query and processes additional tasks per record; almost a poor mans workflow system. The recordsets are broader (in terms of the columns) and deeper (in terms of number of records). We observed that DataSet performs much better in terms of performance but runs into contraints as # of records increase say 100K+ we start seeing System.OutOfMemoryException on a 4G machine with processModel configured to run at memoryLimit set to 85. Since this is a multi-threaded app, there could be multiple threads processing different queries and building different DataSets, so we run into the exception sooner in that case DataReader on the other hand works but is a lot slower and hits other contraints; if there is some sort of disconnect it has to start over again or leaves open connections on the DB side and worst case takes down the service completely etc. So, we decided the best option would be some sort of hybrid solution. I'm open to guidance and suggestions. Are there any hybrid solutions available? Any other suggestions

• Controlling the order of PicoContainer startup

  - by Trejkaz

  I have been tasked with doing some refactoring work on how we start up applications. Basically we have a bunch of console apps which were depending on the GUI application startup code, causing bogus dependencies which have kick-on effects for which libraries we need to ship, and which dependencies other modules need to declare. So I have written a simple startup framework where I basically just throw a bunch of Runnable objects into a list and then run them in order - and it works. But I was thinking - we already have PicoContainer in our project, so all these things that need to be run on startup could potentially be thrown into a PicoContainer, and if they implement Startable they will start... But in some cases we want to specify the ordering between them. For example, I don't want any other component writing to the log before we write a header into the log indicating that the application is starting up. I know I can introduce ordering by introducing injection dependencies, but this feels like a hack in this case - I would need to add the log header writer as a dependency for every other component which might write to the log, which isn't great at all. Nonetheless it seems like it would be nice to control the order of PicoContainer startup, so is there perhaps some other way? Alternatively I could just keep it simple and stick to my list of Runnable. It does, after all, work.

• Replace apostrophe in json string with empty string

  - by user572844

  Hi, I have problem with deserialization of json string, because string is bad format. For example json object consist string property statusMessage with value "Hello "dog" ". The correct format should be "Hello \" dog \" " . I would like remove apostrophes from this property. Something Like this. "Hello "dog" ". - "Hello dog ". Here is it original json string which I work. "{\"jancl\":{\"idUser\":18438201,\"nick\":\"JANCl\",\"photo\":\"1\",\"sex\":1,\"photoAlbums\":1,\"videoAlbums\":0,\"sefNick\":\"jancl\",\"profilPercent\":75,\"emphasis\":false,\"age\":\"-\",\"isBlocked\":false,\"PHOTO\":{\"normal\":\"http://u.aimg.sk/fotky/1843/82/n_18438201.jpg?v=1\",\"medium\":\"http://u.aimg.sk/fotky/1843/82/m_18438201.jpg?v=1\",\"24x24\":\"http://u.aimg.sk/fotky/1843/82/s_18438201.jpg?v=1\"},\"PLUS\":{\"active\":false,\"activeTo\":\"0000-00-00\"},\"LOCATION\":{\"idRegion\":\"6\",\"regionName\":\"Trenciansky kraj\",\"idCity\":\"138\",\"cityName\":\"Trencianske Teplice\"},\"STATUS\":{\"isLoged\":true,\"isChating\":false,\"idChat\":0,\"roomName\":\"\",\"lastLogin\":1294925369},\"PROJECT_STATUS\":{\"photoAlbums\":1,\"photoAlbumsFavs\":0,\"videoAlbums\":0,\"videoAlbumsFavs\":0,\"videoAlbumsExts\":0,\"blogPosts\":0,\"emailNew\":0,\"postaNew\":0,\"clubInvitations\":0,\"dashboardItems\":1},\"STATUS_MESSAGE\":{\"statusMessage\":\"\"Status\"\",\"addTime\":\"1294872330\"},\"isFriend\":false,\"isIamFriend\":false}}" Problem is here, json string consist this object: "STATUS_MESSAGE": {"statusMessage":" "some "bad" value" ", "addTime" :"1294872330"} Condition of string which I want modified: string start with "statusMessage":" string can has any *lenght from 0 -N * string end with ", "addTime So I try write pattern for string which start with "statusMessage":", has any lenght and is ended with ", "addTime. Here is it: const string pattern = " \" statusMessage \" : \" .*? \",\"addTime\" "; var regex = new Regex(pattern, RegexOptions.IgnoreCase); //here i would replace " with empty string string result = regex.Replace(jsonString, match => ???); But I think pattern is wrong, also I don’t know how replace apostrophe with empty string (remove apostrophne). My goal is : "statusMessage":" "some "bad" value" to "statusMessage":" "some bad value" Thank for advice

• After drawing circles on C# form how can i know on what circle i clicked?

  - by SorinA.

  I have to represent graphically an oriented graph like in the image below. i have a C# form, when i click with the mouse on it i have to draw a node. If i click somewhere on the form where is not already a node drawn it means i cliked with the intetion of drawing a node, if it is a node there i must select it and memorize it. On the next mouse click if i touch a place where there is not already a node drawn it means like before that i want to draw a new node, if it is a node where i clicked i need to draw the line from the first memorized node to the selected one and add road cost details. i know how to draw the circles that represent the nodes of the graph when i click on the form. i'm using the following code: namespace RepGraficaAUnuiGraf { public partial class Form1 : Form { Graphics graphDrawingArea; Bitmap bmpDrawingArea; Graphics graph; public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { bmpDrawingArea = new Bitmap(Width, Height); graphDrawingArea = Graphics.FromImage(bmpDrawingArea); graph = Graphics.FromHwnd(this.Handle); } private void Form1_Click(object sender, EventArgs e) { DrawCentralCircle(((MouseEventArgs)e).X, ((MouseEventArgs)e).Y, 15); graph.DrawImage(bmpDrawingArea, 0, 0); } void DrawCentralCircle(int CenterX, int CenterY, int Radius) { int start = CenterX - Radius; int end = CenterY - Radius; int diam = Radius * 2; bmpDrawingArea = new Bitmap(Width, Height); graphDrawingArea = Graphics.FromImage(bmpDrawingArea); graphDrawingArea.DrawEllipse(new Pen(Color.Blue), start, end, diam, diam); graphDrawingArea.DrawString("1", new Font("Tahoma", 13), Brushes.Black, new PointF(CenterX - 8, CenterY - 10)); } } } My question is how can i find out if at the coordinates (x,y) on my form i drew a node and which one is it? I thought of representing the nodes as buttons, having a tag or something similar as the node number(which in drawing should be 1 for Santa Barbara, 2 for Barstow etc.)

• Mobile safari - suppress Unsupported Protocol alert

  - by Juriy

  Hello guys, I'm creating a website for iPhone and i use the native app (cliqcliq Quickpick) to upload photos. I use the script like the following to check if the application is installed. The basic idea is to send user to a custom url, if application is there it is launched, if it is not there the url should be ignored and user is taken to App Store. Below is the script: window.launchQuickpic = function() { var start = new Date(); setTimeout(function() { if (new Date() - start > 2000) { return; } window.location = 'http://www.cliqcliq.com/quickpic/install/'; }, 1000); var getParams = [...]; window.location = 'vquickpic://?' + getParams.join('&'); }; If the native app is not installed I'm getting the alert box saying that Safari does not recognize the custom url. After user clicks "ok" it works as it is supposed to. But the alert is reeealy annoying. I've tried to surround the window.location= code with try/catch. Didn't help.

• Which Project Management Software is adequate for Software & Non-Software Projects?

  - by cusack

  PMS = (Project Management Software) I used trac for software development some time ago. Right now I'm searching for a new more powerful (scheduling, gantt charts, ...) free solution (as in free beer ;-) and free to install on my server) for my current software project. Besides the current software project, abstract project management features like issue-tracking & scheduling would be great for coordinating a group of volunteers for real-life projects as well. I would want one solution for both purposes, so that I have the hassle of installation, getting used to the system and administration only once. So I tried redmine but the problem is it seems to be designed for software projects only. I can't suggest such a solution for the volunteer-group if tickets/issues would have to be of type bug, feature, ... I shortlisted the following six PMS from the wikipedia comparison http://en.wikipedia.org/wiki/List_of_project_management_software Project.net Project-Open Redmine Trac Endeavour Software Project Management eGroupWare I guess they are all more or less fine for software development but would you consider any of these to be good for the non-software project as well? Cliff Notes: I would want a start page situation like in trac. The start-page is a wiki presenting the project and not the PMS. But you can log into the PMS from there. Feature-wish list: wiki, Issue tracking, revision control, scheduling & gantt charts, forums (least important) (Btw: I'm very aware that I can't expect everything to be perfect ;-) 1.)Do you know a suitable solution for software and real-life projects or a highly customizable PMS where I can easily remove sth. like "browse source"(trac) and rename things like ticket/issue-types "bug", "feature"? 2.)Any experience good/bad with the above mentioned six PMS? I would personally guess that "Redmine" and "Endeavour Software Project Management" are too focused on software projects.

• Android always play intro clip

  I'm trying to make my app to play intro clip for only when I start activities. But from my code it's always play the clip after wakeup before resume to app although I did not closed the app. What can I do to fix this prob? Thanks From main: startActivity(new Intent(this, MyIntro.class)); From MyIntro: public class MyIntro extends Activity implements OnCompletionListener { int a; @Override protected void onCreate(Bundle bundle) { super.onCreate(bundle); setContentView(R.layout.intro); playIntro(); } public void onConfigurationChanged(Configuration newConfig) { setContentView(R.layout.intro); } public void onCompletion(MediaPlayer arg0) { // TODO Auto-generated method stub this.finish(); } private void playIntro(){ setContentView(R.layout.intro); VideoView video = (VideoView) this.findViewById(R.id.VideoView01); Uri uri = Uri.parse("android.resource://real.app/" + R.raw.intro); video.setVideoURI(uri); video.requestFocus(); video.setOnCompletionListener(this); video.start(); } }

• Can the Singleton be replaced by Factory?

  - by lostiniceland

  Hello Everyone There are already quite some posts about the Singleton-Pattern around, but I would like to start another one on this topic since I would like to know if the Factory-Pattern would be the right approach to remove this "anti-pattern". In the past I used the singleton quite a lot, also did my fellow collegues since it is so easy to use. For example, the Eclipse IDE or better its workbench-model makes heavy usage of singletons as well. It was due to some posts about E4 (the next big Eclipse version) that made me start to rethink the singleton. The bottom line was that due to this singletons the dependecies in Eclipse 3.x are tightly coupled. Lets assume I want to get rid of all singletons completely and instead use factories. My thoughts were as follows: hide complexity less coupling I have control over how many instances are created (just store the reference I a private field of the factory) mock the factory for testing (with Dependency Injection) when it is behind an interface In some cases the factories can make more than one singleton obsolete (depending on business logic/component composition) Does this make sense? If not, please give good reasons for why you think so. An alternative solution is also appreciated. Thanks Marc

• GridView onTouch

  - by Jeff

  I am trying to set up a GridView of buttons that responds to onTouch. For example, if I swipe my finger across the screen horizontally, vertically or diagonally then I want the buttons which were touched to be selected. I tried setting OnTouchListener's for the buttons, but this didn't work, only the first button in the drag event received the onTouch events. Next I tried creating an OnTouchListener for the GridView and then using the X,Y coords to determine which buttons where touched. This doesn't seem to work either since the MOTION_DOWN events are only passed to the GridView's onTouch() if I start the drag on the very edge of the GridView. In fact if I drag my finger horizontally across the grid, the onTouch events aren't fired at all unless I start the drag at the edge of the GridView. Does anyone know of a better way to do this? Thanks in advance. gridview.setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(@SuppressWarnings("unused") View view, MotionEvent event) { float X = event.getX(); float Y = event.getY(); switch (event.getAction()) { case MotionEvent.ACTION_DOWN: System.out.println("Down: " + X + "," + Y); break; case MotionEvent.ACTION_MOVE: System.out.println("Move: " + X + "," + Y); break; case MotionEvent.ACTION_UP: System.out.println("Up: " + X + "," + Y); break; } return true; } }

• Run a PHP script every second using CLI

  - by Saif Bechan

  Hello, I have a dedicated server running Cent OS with a Parallel PLESK panel. I need to run a php script every second, that updates my database. These is no alternative way timewise, i have checked every method, it needs to be updated every second. I can find my script using the url: http://www.mysite.com/phpfile.php?key=123, and this has to be executed every second. Does anyone have any knowledge at all on doing this, i can not seem to find the answer. I heard about doing it with CLI and putty, but i have no knowledge of this at all. Or can this be done using the PLESK Panel? And can the file be executed locally every second. Like \phpfile.php If someone helps me on answering these question i would really appreciate it. Regards EDIT It has been a few months since i added this question. I ended up using the following code: #!/user/bin/php $start = microtime(true); set_time_limit(60); for (i = 0; i < 59; ++$i) { doMyThings(); time_sleep_until($start + $i + 1); } Thank you for this code guys! My cronjob is set to every minute. I have been running this for some time now in a test environment, and this works out great. It works really supperfast, and i see no increase in CPU nor Memory usage.

• Error trying to use rand from std library cstdlib with g++

  - by Matt

  I was trying to use the random function in Ubuntu compiling with g++ on a larger program and for some reason rand just gave weird compile errors. For testing purposes I made the simplest program I could and it still gives errors. Program: #include <iostream> using std::cout; using std::endl; #include <cstdlib> int main() { cout << "Random number " << rand(); return 0; } Error when compiling with the terminal sudo g++ chapter_3/tester.cpp ./test ./test: In function _start': /build/buildd/eglibc-2.10.1/csu/../sysdeps/i386/elf/start.S:65: multiple definition of_start' /usr/lib/gcc/i486-linux-gnu/4.4.1/../../../../lib/crt1.o:/build/buildd/eglibc-2.10.1/csu/../sysdeps/i386/elf/start.S:65: first defined here ./test:(.rodata+0x0): multiple definition of _fp_hw' /usr/lib/gcc/i486-linux-gnu/4.4.1/../../../../lib/crt1.o:(.rodata+0x0): first defined here ./test: In function_fini': (.fini+0x0): multiple definition of _fini' /usr/lib/gcc/i486-linux-gnu/4.4.1/../../../../lib/crti.o:(.fini+0x0): first defined here ./test:(.rodata+0x4): multiple definition of_IO_stdin_used' /usr/lib/gcc/i486-linux-gnu/4.4.1/../../../../lib/crt1.o:(.rodata.cst4+0x0): first defined here ./test: In function __data_start': (.data+0x0): multiple definition ofdata_start' /usr/lib/gcc/i486-linux-gnu/4.4.1/../../../../lib/crt1.o:(.data+0x0): first defined here ./test: In function __data_start': (.data+0x4): multiple definition of__dso_handle' /usr/lib/gcc/i486-linux-gnu/4.4.1/crtbegin.o:(.data+0x0): first defined here ./test: In function main': (.text+0xb4): multiple definition ofmain' /tmp/cceF0x0p.o:tester.cpp:(.text+0x0): first defined here ./test: In function _init': (.init+0x0): multiple definition ofinit' /usr/lib/gcc/i486-linux-gnu/4.4.1/../../../../lib/crti.o:(.init+0x0): first defined here /usr/lib/gcc/i486-linux-gnu/4.4.1/crtend.o:(.dtors+0x0): multiple definition of `_DTOR_END' ./test:(.dtors+0x4): first defined here /usr/bin/ld: error in ./test(.eh_frame); no .eh_frame_hdr table will be created. collect2: ld returned 1 exit status

• Python 3.0 IDE - Komodo and Eclipse both flaky?

  - by victorhooi

  heya, I'm trying to find a decent IDE that supports Python 3.x, and offers code completion/in-built Pydocs viewer, Mercurial integration, and SSH/SFTP support. Anyhow, I'm trying Pydev, and I open up a .py file, it's in the Pydev perspective and the Run As doesn't offer any options. It does when you start a Pydev project, but I don't want to start a project just to edit one single Python script, lol, I want to just open a .py file and have It Just Work... Plan 2, I try Komodo 6 Alpha 2. I actually quite like Komodo, and it's nice and snappy, offers in-built Mercurial support, as well as in-built SSH support (although it lacks SSH HTTP Proxy support, which is slightly annoying). However, for some reason, this refuses to pick up Python 3. In Edit-Preferences-Languages, there's two option, one for Python and Python3, but the Python3 one refuses to work, with either the official Python.org binaries, or ActiveState's own ActivePython 3. Of course, I can set the "Python" interpreter to the 3.1 binary, but that's an ugly hack and breaks Python 2.x support. So, does anybody who uses an IDE for Python have any suggestions on either of these accounts, or can you recommend an alternate IDE for Python 3.0 development? Cheers, Victor

• Can I print an HTMLLoader (pdf) in Adobe Air?

  - by Stephano

  I'm using AlivePDF to create a PDF file, then save it to the desktop. I can then use an HTMLLoader to display my lovely PDF file. Now, the print button in Adobe Reader works fine. However, there will be young children using the app, so I'd like to have a big "Print" button right above it. I figured I could just start up a print job and feed it my HTMLLoader. Am I doing something wrong here, cause I can't seem to get any output? note: variable "stuff" below is my HTMLLoader. I also have access to the PDF file if that comes in handy. private function print():void { var myPrintJob:PrintJob=new PrintJob(); var result:Boolean=myPrintJob.start(); if (result && stuff != null) { var rect:Rectangle=new Rectangle(0, 0, 2550, 3300); var opt:PrintJobOptions=new PrintJobOptions(true); myPrintJob.addPage(stuff, rect, opt); myPrintJob.send(); } else { //User does not have printer or user canceled print action } }

• windows beneath not being painted when using a layered window

  - by Nuno

  Hi, I will try to explain my problem the best i can, I'm creating a layered window in c++ (using windowsXP), all works fine until i drag my created window near the windows start button, and then when i press the star button of windows taskbar and close it again all the windows beneath of my layered window aren't being painted (only in the area of the start window that pops over my window). My create window is like this: CWnd::CreateEx( WS_EX_TOOLWINDOW | WS_EX_LAYERED, AfxRegisterWndClass(0), lpstr_name, WS_POPUP, 0,0,0,0, pc_parent-GetSafeHwnd(), 0); ... When i create the window with this styles the problem ocurrs, but if i create with the extended style WS_EX_TRANSPARENT and all the others the problem does not occur any more. And if instead of a WS_POPUP window is a WS_CHILD or WS_OVERLAPPED then this also doesn't occur... Can anyone please explain why when i create a WS_POPUP window with the WS_EX_LAYERED style all the beneath windows aren't updated, and if i add the style WS_EX_TRANSPARENT this works fine. Note: why i do not use the WS_EX_TRANSPARENT style if it works right? if i use it then my window can not be dragged and i need it to do it :) Thanks

• form layout in drupal from a module

  - by EricP

  I created my own module called "cssswitch". I'm trying to create my own html layout to display the admin form portion of the module. I understand how to use the hook_form_alter() to modify form elements, but I need to create the entire form layout to make some fields appear next to each other. It seems I need something like the way I have the frontend view of the node displayed with theme_cssswitch_display(), but for the admin part of the node. function cssswitch_form_alter(&$form, $form_state, $form_id) { switch($form_id) { case 'cssswitch_node_form': $form['hour_start']['#prefix'] = '<div class="start-box">'; $form['ampm_start']['#suffix'] = '</div>'; $form['ampm_start']['#attributes'] = array("style" => "border-width:2px;"); break; } } function cssswitch_theme() { return array( 'cssswitch_display' => array( 'arguments' => array('node'), ), ); } // to display the view of the node function theme_cssswitch_display($node) { $output = '<div class="cssswitch-cssfilename">Filename: '. check_plain($node->cssfilename). '</div>'; $output .= '<div class="cssswitch-time_start">Start: '. check_plain($node->hour_start). ':'.check_plain($node->minute_start).' '.check_plain($node->ampm_start).'</div>'; $output .= '<div class="cssswitch-time_end">End: '. check_plain($node->hour_end). ':'.check_plain($node->minute_end).' '.check_plain($node->ampm_end).'</div>'; return $output; } thanks for any help

• GAE datastore querying integer fields

  - by ParanoidAndroid

  I notice strange behavior when querying the GAE datastore. Under certain circumstances Filter does not work for integer fields. The following java code reproduces the problem: log.info("start experiment"); DatastoreService datastore = DatastoreServiceFactory.getDatastoreService(); int val = 777; // create and store the first entity. Entity testEntity1 = new Entity(KeyFactory.createKey("Test", "entity1")); Object value = new Integer(val); testEntity1.setProperty("field", value); datastore.put(testEntity1); // create the second entity by using BeanUtils. Test test2 = new Test(); // just a regular bean with an int field test2.setField(val); Entity testEntity2 = new Entity(KeyFactory.createKey("Test", "entity2")); Map<String, Object> description = BeanUtilsBean.getInstance().describe(test2); for(Entry<String,Object> entry:description.entrySet()){ testEntity2.setProperty(entry.getKey(), entry.getValue()); } datastore.put(testEntity2); // now try to retrieve the entities from the database... Filter equalFilter = new FilterPredicate("field", FilterOperator.EQUAL, val); Query q = new Query("Test").setFilter(equalFilter); Iterator<Entity> iter = datastore.prepare(q).asIterator(); while (iter.hasNext()) { log.info("found entity: " + iter.next().getKey()); } log.info("experiment finished"); the log looks like this: INFO: start experiment INFO: found entity: Test("entity1") INFO: experiment finished For some reason it only finds the first entity even though both entities are actually stored in the datastore and both 'field' values are 777 (I see it in the Datastore Viewer)! Why does it matter how the entity is created? I would like to use BeanUtils, because it is convenient. The same problem occurs on the local devserver and when deployed to GAE.
