  • Getting logging.debug() to work on Google App Engine/Python

    - by brainjam
    I'm just getting started on building a Python app for Google App Engine. In the localhost environment I'm trying to send debug info to the GoogleAppEngineLauncher Log Console via logging.debug(), but it isn't showing up. However, anything sent through, say, logging.info() or logging.error() does show up. I've tried a logging.basicConfig(level=logging.DEBUG) before the logging.debug(), but to no avail. What am I missing?

  • Drawing text to <canvas> with @font-face does not work at the first time

    - by lemonedo
    Hi all, First try the test case please: http://lemon-factory.net/test/font-face-and-canvas.html I'm not good at English, so I made the test case to be self-explanatory. On the first click to the DRAW button, it will not draw text, or will draw with an incorrect typeface instead of the specified "PressStart", according to your browser. After then it works as expected. At the first time the text does not appear correctly in all browsers I've tested (Firefox, Google Chrome, Safari, Opera). Is it the standard behavior or something? Thank you. PS: Following is the code of the test case <!DOCTYPE html> <html> <head> <meta http-equiv=Content-Type content="text/html;charset=utf-8"> <title>@font-face and canvas</title> <style> @font-face { font-family: 'PressStart'; src: url('http://lemon-factory.net/css/fonts/prstart.ttf'); } canvas, pre { border: 1px solid #666; } pre { float: left; margin: .5em; padding: .5em; } </style> </head> <body> <div> <canvas id=canvas width=250 height=250> Your browser does not support the CANVAS element. Try the latest Firefox, Google Chrome, Safari or Opera. </canvas> <button>DRAW</button> </div> <pre id=style></pre> <pre id=script></pre> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script> var canvas = document.getElementById('canvas') var ctx = canvas.getContext('2d') var x = 30 var y = 10 function draw() { ctx.font = '12px PressStart' ctx.fillStyle = '#000' ctx.fillText('Hello, world!', x, y += 20) ctx.fillRect(x - 20, y - 10, 10, 10) } $('button').click(draw) $('pre#style').text($('style').text()) $('pre#script').text($('script').text()) </script> </body> </html>

  • XMPP4R Callbacks dont seem to work

    - by Sid
    Im using xmpp4r and trying to get the hang of a basic chat feature that I wish to implement later in my Rails app. My fundamentals on Ruby Threads is still a bit shaky so I would appreciate any help on this. Though I register the callback i dont get a response from my gmail account. I am able to send a message but my ruby program terminates. In order to prevent it from terminating I tried to stop on of the threads in the program but I cant seem to get it working. require 'rubygems' require "xmpp4r/client" require "xmpp4r/roster" include Jabber def connect client = Client.new(JID::new("[email protected]")) client.connect client.auth("test") client.send(Presence.new.set_type(:available)) client end def create_message(message, to_email) msg = Jabber::Message::new(to_email, message) msg.type = :chat msg end def subscribe(email_id) pres = Presence.new.set_type(:subscribe).set_to(email_id) pres end client = connect roster = Roster::Helper.new(client) roster.add_subscription_request_callback do |item,pres| roster.accept_subscription(pres.from) end def create_callback(client) $t4= Thread.new do client.add_message_callback do |m| puts m.body puts "................................Callback working" end end end puts "Client has connected" msg = create_message("Welcome to the winter of my discontent", "[email protected]") client.send(msg) create_callback(client) def check(client) $t3 = Thread.new do loop do puts "t3 still running........." Thread.current.stop $t4.join end end end check(client)

  • How does AssemblyName.ReferenceMatchesDefinition work?

    - by Fabian Schmied
    Given the following code: var n1 = new AssemblyName ("TestDll, Version=1.0.0.0, Culture=Neutral, PublicKeyToken=b77a5c561934e089"); var n2 = new AssemblyName ("TestDll, Version=2.0.0.2001, Culture=en-US, PublicKeyToken=ab7a5c561934e089"); Console.WriteLine (AssemblyName.ReferenceMatchesDefinition (n1, n2)); Console.WriteLine (AssemblyName.ReferenceMatchesDefinition (n2, n1)); Why do both of these checks print "True"? I would have thought that AssemblyName.ReferenceMatchesDefinition should consider differences in the version, culture, and public key token attributes of an assembly name, shouldn't they? If not, what does ReferenceMatchesDefinition do that a comparison of the simple names doesn't?

  • JQuery val() does not work for textarea in Opera

    - by Anil Soman
    I am displaying a modal dialog using jQuery. This dialog has a textarea control on it. But on submitting this dialog, the value of this textarea is not recognized by jQyery for some reason. It always comes blank. This works perfectly in other browsers. I put alert to display the value but it looks blank. Can anybody help me in this regards? Controls <input type="text" id="txtGroupName"/> <textarea rows="3" cols="30" id="txtDescription"></textarea> jQuery code which used this value var postData = new Object(); postData.GroupName = $('#txtGroupName').val(); postData.Description = $('#txtDescription').val(); $('#txtDescription').val() comes blank but $('#txtGroupName').val() is read correctly as it is a input field. One more finding about this issue: When I put alert in my update function after populating the control value on page load, this alert displays the existing value properly. But it displays only existing value. It does not display the edited value after submitting the modal box.

  • how floating point numbers work in C

    - by hatorade
    Let's say I have this: float i = 1.5 in binary, this float is represented as: 0 01111111 10000000000000000000000 I broke up the binary to represent the 'signed', 'exponent' and 'fraction' chunks. What I don't understand is how this represents 1.5. The exponent is 0 once you subtract the bias (127 - 127), and the fraction part with the implicit leading one is 1.1. How does 1.1 scaled by nothing = 1.5???

  • Updating multiple tables with LinqToSql in one unit of work

    Table 1: int ID-a(pk) Table 2: int ID-a(pk), int ID-b(pk) Table 3: int ID-b(pk), string C I have the data to insert into Table 1. But I do not have the ID-a, which is autogenerated. I have many string C to insert in Table 3. I am trying to insert row into Table 1, get the ID-a to insert in Table 2 along with the ID-b that is auto-Generated in Table 3 when I submit each string C, all in one submission to db. Right now I am calling dc.SubmitChanges twice in same call. Is it efficient to have to submit changes twice on same DataContext or can this be combined further?

  • Android x86 porting, unable to make it work

    - by Mr G
    I'm kind of new to the whole porting issue and I got to it because of the slowness in the emulator provided with the Android SDK. I downloaded the android-x86-3.2-RC2-eeepc and android-x86-3.2-RC2-tegav2 ISO-es (from this site) and tried them on the VirtualBox but have no internet connection on the eeepc version and the tegev2 wont event start. I tried the VirtualBoxHowTo but got nothing, on both Windows and Linux platforms. the only thing I managed to understand is that to use this on a VM you need to build it for VM. Can anyone help me on this? P.S.: I need the HoneyComb version (3.2) and the pc I have is a AMD 6 core on and Asus Crosshair Extreme motherboard, Windows 7 or Ubunutu 11.10. (both OS are 64bit)

  • PPR in tr:selectOneChoice does not work

    - by Nhut Le
    Hi, I have a simple testing page that test my PPR on a selectOneChoice component. when select a value from selectOnechoice 1, the selected value will display on a output label and also reset the selected value and the other selectOneChoice. However, it prints the selected values to the label correctly but it can't set the selected value for the other selectOneChoice. and Here are my page and my value change event method. <tr:form id="nhutForm"> <tr:selectOneChoice id="one" value="#{nhutTestBean.one}" autoSubmit="true" immediate="true" valueChangeListener="#{nhutTestBean.onMyValueChanged}"> <tr:selectItem label="0" value="0"/> <tr:selectItem label="1" value="1"/> <tr:selectItem label="2" value="2"/> <tr:selectItem label="3" value="3"/> </tr:selectOneChoice> <tr:selectOneChoice id="two" value="#{nhutTestBean.two}" partialTriggers="one"> <f:selectItems value="#{nhutTestBean.myList}"/> </tr:selectOneChoice> <tr:outputText id="nhutTextBox" value="hello: #{nhutTestBean.output}" partialTriggers="one"/></tr:form> and my valueChangeEvent method: public void onMyValueChanged(ValueChangeEvent event) { this.setOutput((String)event.getNewValue()); this.setTwo((String)event.getNewValue()); } One thing I realize is that it calls my setTwo twice, the first the set the correct values, but the second time set it to null so that nothing would be selected for the two drop down box. please help. thank you so much.

  • JSONArray does not work when I am getting the JSON string from the server

    - by Taehoon A Kim
    I've looked up some answers but am not sure why mine is failing exactly... The code looks something like this HttpResponse httpResponse = httpClient.execute(httpPost); HttpEntity httpEntity = httpResponse.getEntity(); String json = EntityUtils.toString(httpEntity); //Convert to JsonArray JSONArray jsonArray = new JSONArray(json); Log.i(DEBUG_TAG, Integer.toString(jsonArray.length())); for (int i = 0; i < jsonArray.length(); i++) { JSONObject jsonObject = jsonArray.getJSONObject(i); Log.i(DEBUG_TAG, jsonObject.getString(KEY_ID)); // creating new HashMap HashMap<String, String> map = new HashMap<String, String>(); // adding each child node to HashMap key => value map.put(KEY_ID, jsonObject.getString(KEY_ID)); map.put(KEY_TITLE, jsonObject.getString(KEY_TITLE)); map.put(KEY_ARTIST, jsonObject.getString(KEY_ARTIST)); map.put(KEY_DURATION, jsonObject.getString(KEY_DURATION)); map.put(KEY_VOTECOUNT, jsonObject.getString(KEY_VOTECOUNT)); map.put(KEY_THUMB_URL, jsonObject.getString(KEY_THUMB_URL)); map.put(KEY_GENRE, jsonObject.getString(KEY_GENRE)); //Adding map to ArrayList if (Integer.parseInt(jsonObject.getString(KEY_VOTECOUNT)) == -1){ //If VoteCount is -1 then add to header headerList.add(map); }else { songsList.add(map); } } } catch (UnsupportedEncodingException e) { e.printStackTrace(); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } When I run logcat on String json, it seems to show correct info which is kind of like this... { "userdata": [ { "id": "8", "title": "Baby One More Time", "artist": "Britney Spears", "duration": "03:24:00", "votes": "0", "thumb_url": "http://api.androidhive.info/music/images/dido.png", "genre": null }, { "id": "2", "title": "As Long As You Love Me", "artist": "Justin Bieber", "duration": "05:26:00", "votes": "0", "thumb_url": "http://api.androidhive.info/music/images/enrique.png", "genre": "Rock" } ] } and the logcat on JSONArray jsonArray = new JSONArray(json); tells me that jsonArray.length() 10-31 22:57:28.433: W/CustomizedListView(26945): error! Invalid index 0, size is 0 Please let me know Thank you,

  • how do simple SQLAlchemy relationships work?

    - by Carson Myers
    I'm no database expert -- I just know the basics, really. I've picked up SQLAlchemy for a small project, and I'm using the declarative base configuration rather than the "normal" way. This way seems a lot simpler. However, while setting up my database schema, I realized I don't understand some database relationship concepts. If I had a many-to-one relationship before, for example, articles by authors (where each article could be written by only a single author), I would put an author_id field in my articles column. But SQLAlchemy has this ForeignKey object, and a relationship function with a backref kwarg, and I have no idea what any of it MEANS. I'm scared to find out what a many-to-many relationship with an intermediate table looks like (when I need additional data about each relationship). Can someone demystify this for me? Right now I'm setting up to allow openID auth for my application. So I've got this: from __init__ import Base from sqlalchemy.schema import Column from sqlalchemy.types import Integer, String class Users(Base): __tablename__ = 'users' id = Column(Integer, primary_key=True) username = Column(String, unique=True) email = Column(String) password = Column(String) salt = Column(String) class OpenID(Base): __tablename__ = 'openid' url = Column(String, primary_key=True) user_id = #? I think the ? should be replaced by Column(Integer, ForeignKey('users.id')), but I'm not sure -- and do I need to put openids = relationship("OpenID", backref="users") in the Users class? Why? What does it do? What is a backref?

  • Need to work out database structure

    - by jim smith
    Hi, Just need a little kickstart with this. I have Mysql/PHP, and I have 5,000 products. I have 30 companies I need to store some data for those 30 companies for each product as follows: a) prices b) stock qty I also need to store data historically on a daily basis. So the table... It makes sense that the records will be the products because there's 5000, and if I put the companies as the columns, I can store the prices, but what about the stock quantities? I could create two columns for each compoany, one for prices, one for qty. Then make the tablename the date for that day...so theer would be a new table for every day with 5000 products in it? is this the correct way? Some idea on how I'll be retreiving data the top 5 lowest prices (and the company) by product for a certain date the price and stock changes in the past 7 days by product

  • NSMutableURLRequest and a Password with special Characters won't work

    - by twickl
    I'm writing a small program (using Cocoa Touch), which communicates with a webservice. The code for calling the webservice, is the following: - (IBAction)send:(id)sender { if ([number.text length] > 0) { [[UIApplication sharedApplication] beginIgnoringInteractionEvents]; [activityIndicator startAnimating]; NSString *modded; modded = [self computeNumber]; NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL: [NSURL URLWithString:@"https://tester:%=&[email protected]/RPC2"]]; [theRequest setHTTPMethod:@"POST"]; [theRequest addValue:@"text/xml" forHTTPHeaderField:@"content-type"]; [theRequest setCachePolicy:NSURLCacheStorageNotAllowed]; [theRequest setTimeoutInterval:5.0]; NSString* pStr = [[NSString alloc] initWithFormat:@"<?xml version=\"1.0\" encoding=\"UTF-8\"?><methodCall><methodName>samurai.SessionInitiate</methodName><params><param><value><struct><member><name>LocalUri</name><value><string></string></value></member><member><name>RemoteUri</name><value><string>sip:%@@sipgate.net</string></value></member><member><name>TOS</name><value><string>text</string></value></member><member><name>Content</name><value><string>%@</string></value></member><member><name>Schedule</name><value><string></string></value></member></struct></value></param></params></methodCall>", modded, TextView.text]; NSData* pBody = [pStr dataUsingEncoding:NSUTF8StringEncoding]; [theRequest setHTTPBody:pBody]; NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; if (!theConnection) { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"A Connection could not be established!" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil]; [alert show]; [alert release]; sendButton.enabled = TRUE; return; } [pStr release]; [pBody release]; } } The Username and Password have to be in the URL, and it works in most cases, but when the password consists of special characters like in the example "%=&=-Test2009", the Webservice does not respond. If it is something like "Test2009" it works fine. Does anyone have an idea why, and maybe a solution for that?

  • Strange problems with PHP SOAP (private variable not persist + variables passed from client not work

    - by Tamas Gal
    I have a very strange problems in a PHP Soap implementation. I have a private variable in the Server class which contains the DB name for further reference. The private variable name is "fromdb". I have a public function on the soap server where I can set this variable. $client-setFromdb. When I call it form my client works perfectly and the fromdb private variable can be set. But a second soap client call this private variable loses its value... Here is my soap server setup: ini_set('soap.wsdl_cache_enabled', 0); ini_set('session.auto_start', 0); ini_set('always_populate_raw_post_data', 1); global $config_dir; session_start(); /*if(!$HTTP_RAW_POST_DATA){ $HTTP_RAW_POST_DATA = file_get_contents('php://input'); }*/ $server = new SoapServer("{$config_dir['template']}import.wsdl"); $server-setClass('import'); $server-setPersistence(SOAP_PERSISTENCE_SESSION); $server-handle(); Problem is that I passed this to the server: $client = new SoapClient('http://import.ingatlan.net/wsdl', array('trace' = 1)); $xml=''; $xml.=''; $xml.=''; $xml.=''; $xml.='Valaki'; $xml.=''; $xml.=''; $xml.=''; $xml.=''; $tarray = array("type" = 1, "xml" = $xml); try{ $s = $client-sendXml( $tarray ); print "$s"; } catch( SOAPFault $exception){ print "--- SOAP exception :{$exception}---"; print "LAST REQUEST :"; var_dump($client-_getLastRequest()); print "---"; print "LAST RESPONSE :".$client-_getLastResponse(); } So passed an Array of informations to the server. Then I got this exception: LAST REQUEST : <?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"><SOAP-ENV:Body><type>Array</type><xml/></SOAP-ENV:Body></SOAP-ENV:Envelope> Can you see the Array word between the type tag? Seems that the client only passed a reference or something like this. So I totaly missed :(

  • How do the versions of Guava work?

    - by Frór
    I would like to use Guava in a project, but my PM doesn't like the "r05" suffix, saying that it looks like it's not stable. In fact, the part I need is only the Google-Collections 1.0 which is now deprecated (my PM doesn't like that word either). So I don't really get the versioning of Guava/Google-Collections. I'm currently doing the development with GC1.0, but if possible I'll switch to a more recent and stable version.

  • Does Scheme work with Microsoft COM?

    - by Martin
    I'm new to Scheme -- the functional programming language and I like it a lot for its first-class/higher-order functions. However, my data comes from a COM source with an object-oriented API. I know Scheme and COM belong to different programming paradigms, but I'm wondering if there is any interface or a way for Scheme to connect to a COM source? Thanks.

  • Flowlayout panel and autosizing child controls doesn't work

    - by Pete
    I am trying to get a very simple autosizing layout on a winform (C# .NET). I've tried TableLayoutPanels and FlowLayoutPanels but nothing works. I have a usercontrol which is a container for other usercontrols which are created at runtime - I've called it StackPanel as I want it to list the child controls vertically. I've tried this using a FlowLayoutPanel, TableLayoutPanel and a Panel (with each control docked to the top). The child usercontrol consists of a label and then any number of radiobuttons (or any other standard control - it doesn't matter). When the child controls are created, the label text is set (if this is long it needs to wrap to a new line) and the radio buttons are added. There seems to be no combination of docking/autosizing or manual size setting using the Resize events that can get everything to show without clipping and still resize with the form. Thanks!
