• How to align Definition Lists in IE6 ?

  - by ellander

  I'm having a major headache trying to align some and elements in ie6. It looks fine in ie7 and firefox but the dt elements don't appear in ie6. can anyone help? here is the code.. <div id="listMembers"> <h3>Members</h3> <dl class="myDL"> <dt>Name</dt> <dd>John Smith</dd> <dt>Address</dt> <dd>the street</dd> ... </dl> <div id="listOptions"> <div> <table>...</table> </div> </div> <div> and the css:- DL.myDL { BORDER-RIGHT: black 2px outset; PADDING-RIGHT: 2px; BORDER-TOP: black 2px outset; DISPLAY: block; PADDING-LEFT: 2px; BACKGROUND: #ccbe99; PADDING-BOTTOM: 2px; BORDER-LEFT: black 2px outset; WIDTH: auto; PADDING-TOP: 2px; BORDER-BOTTOM: black 2px outset; FONT-FAMILY: "Trebuchet MS", Arial, sans-serif } DL.myDL DT { CLEAR: both; PADDING-RIGHT: 3px; DISPLAY: inline; FLOAT: left; WIDTH: 250px; TEXT-ALIGN: right } I basically want the dt text aligned to the right and the dd on the right hand side with left align text. I reset the margin on all elements to be 0 before anything else in the css and the elements are within a dive with position relative.

• Stop running this script, IE7 using PHP

  - by Jomel Dicen

  I incorporate javascript in my PHP program: Try to check my codes. It loops depend on the number of records in database. for instance: $counter = 0; foreach($row_value as $data): echo $this->javascript($counter, $data->exrate, $data->tab); endforeach; private function javascript($counter=NULL, $exrate=NULL, $tab=NULL){ $js = " <script type='text/javascript'> $(function () { var textBox0 = $('input:text[id$=quantity{$counter}]').keyup(foo); var textBox1 = $('input:text[id$=mc{$counter}]').keyup(foo); var textBox2 = $('input:text[id$=lc{$counter}]').keyup(foo); function foo() { var value0 = textBox0.val(); var value1 = textBox1.val(); var value2 = textBox2.val(); var sum = add(value1, value2) * (value0 * {$exrate}); $('input:text[id$=result{$counter}]').val(parseFloat(sum).toFixed(2)); // Compute Total Quantity var qtotal = 0; $('.quantity{$tab}').each(function() { qtotal += Number($(this).val()); }); $('#tquantity{$tab}').text(qtotal); // Compute MC UNIT var mctotal = 0; $('.mc{$tab}').each(function() { mctotal += Number($(this).val()); }); $('#tmc{$tab}').text(mctotal); // Compute LC UNIT var lctotal = 0; $('.lc{$tab}').each(function() { lctotal += Number($(this).val()); }); $('#tlc{$tab}').text(lctotal); // Compute Result var result = 0; $('.result{$tab}').each(function() { result += Number($(this).val()); }); $('#tresult{$tab}').text(result); } function add() { var sum = 0; for (var i = 0, j = arguments.length; i < j; i++) { if (IsNumeric(arguments[i])) { sum += parseFloat(arguments[i]); } } return sum; } function IsNumeric(input) { return (input - 0) == input && input.length > 0; } }); </script> "; return $js; } When I running this on IE this message is always annoying me " Stop running this script? A script on this page is causing your web browser to run slowly. If it continues to run, your computer might become unresponsive." but in firefox it's functioning well.

• jquery .get/.post not working on ie 7 or 8, works fine in ff

  - by Samutz

  I have basically this on a page: <script type="text/javascript"> function refresh_context() { $("#ajax-context").html("Searching..."); $.get("/ajax/ldap_search.php", {cn: $("#username").val()}, function(xml) { $("#ajax-context").html($("display", xml).text()); $("#context").val($("context", xml).text()); }, 'xml'); } $(document).ready(function() { $("#username").blur(refresh_context); }); </script> <input type="text" name="username" id="username" maxlength="255" value="" /> <input type="hidden" name="context" id="context" value=""/> <div id="ajax-context"></div> What it should do (and does fine on Firefox) is when you type a username in to the #username field, it will run /ajax/ldap_search.php?cn=$username, which searches our company's ldap for the username and returns it's raw context and a formatted version of the context like this: <result> <display>Staff -&gt; Accounting -&gt; John Smith</display> <context>cn=jsmith,ou=Accounting,ou=Staff,ou=Users,o=MyOrg</context> </result> The formatted version (display) goes to the div #ajax-context and goes to the hidden input #context. (Also, the - are actually - "& g t ;" (without spaces)). However, on IE the div stays stuck on "Searching..." and the hidden input value stays blank. I've tried both .get and .post and neither work. I'm sure it's failing on the .get because if I try this, I don't even get the alert: $.get("/ajax/ldap_search.php", {cn: $("#username").val()}, function() { alert("Check"); }); Also, IE doesn't give me any script errors. Edit: Added "$(document).ready(function() {", the .blur was already in it in my code, but I forgot to include that in my post. Edit 2: The request is being sent and apache2 is receiving it: 10.135.128.96 - - [01/May/2009:10:04:27 -0500] "GET /ajax/ldap_search.php?cn=i_typed_this_in_IE HTTP/1.1" 200 69

• Use `require()` with `node --eval`

• Is safe ( documented behaviour? ) to delete the domain of an iterator in execution

  - by PoorLuzer

  I wanted to know if is safe ( documented behaviour? ) to delete the domain space of an iterator in execution in Python. Consider the code: import os import sys sampleSpace = [ x*x for x in range( 7 ) ] print sampleSpace for dx in sampleSpace: print str( dx ) if dx == 1: del sampleSpace[ 1 ] del sampleSpace[ 3 ] elif dx == 25: del sampleSpace[ -1 ] print sampleSpace 'sampleSpace' is what I call 'the domain space of an iterator' ( if there is a more appropriate word/phrase, lemme know ). What I am doing is deleting values from it while the iterator 'dx' is running through it. Here is what I expect from the code : Iteration versus element being pointed to (*): 0: [*0, 1, 4, 9, 16, 25, 36] 1: [0, *1, 4, 9, 16, 25, 36] ( delete 2nd and 5th element after this iteration ) 2: [0, 4, *9, 25, 36] 3: [0, 4, 9, *25, 36] ( delete -1th element after this iteration ) 4: [0, 4, 9, 25*] ( as the iterator points to nothing/end of list, the loop terminates ) .. and here is what I get: [0, 1, 4, 9, 16, 25, 36] 0 1 9 25 [0, 4, 9, 25] As you can see - what I expect is what I get - which is contrary to the behaviour I have had from other languages in such a scenario. Hence - I wanted to ask you if there is some rule like "the iterator becomes invalid if you mutate its space during iteration" in Python? Is it safe ( documented behaviour? ) in Python to do stuff like this?

• cURL/PHP Request Executes 50% of the Time

  - by makavelli

  After searching all over, I can't understand why cURL requests issued to a remote SSL-enabled host are successful only 50% or so of the time in my case. Here's the situation: I have a sequence of cURL requests, all of them issued to a HTTPS remote host, within a single PHP script that I run using the PHP CLI. Occasionally when I run the script the requests execute successfully, but for some reason most of the times I run it I get the following error from cURL: * About to connect() to www.virginia.edu port 443 (#0) * Trying 128.143.22.36... * connected * Connected to www.virginia.edu (128.143.22.36) port 443 (#0) * successfully set certificate verify locations: * CAfile: none CApath: /etc/ssl/certs * error:140943FC:SSL routines:SSL3_READ_BYTES:sslv3 alert bad record mac * Closing connection #0 If I try again a few times I get the same result, but then after a few tries the requests will go through successfully. Running the script after that again results in an error, and the pattern continues. Researching the error 'alert bad record mac' didn't give me anything helpful, and I hesitate to blame it on an SSL issue since the script still runs occasionally. I'm on Ubuntu Server 10.04, with php5 and php5-curl installed, as well as the latest version of openssl. In terms of cURL specific options, CURLOPT_SSL_VERIFYPEER is set to false, and both CURLOPT_TIMEOUT and CURLOPT_CONNECTTIMEOUT are set to 4 seconds. Further illustrating this problem is the fact that the same exact situation occurs on my Mac OS X dev machine - the requests only go through ~50% of the time.

• Combining two exe files

  - by Sophia

  Here's some background to my problem: I have a project in Visual C++ 2006 and a project in in Visual C++ 2010 Express. Both compiles to form an exe file each. I cannot convert my 2006 project to 2010 because I get a lot of "unable to load project" errors. I also cannot port my 2010 project code to 2006 (I always get errors no matter what I try, something to do with libraries). My final solution requires me to only have ONE executable. Is there anything I can do to achieve that? I've done some quick search on Google and found there to be exe joiners, but I've also heard that those things are often used to make malware. For reference, I am working with "dummy" clients, and therefore want to simplify things on their end as much as possible. Thus, having them executing one exe is better than having them execute two. Also, I do not wish for their antivirus to go haywire because I used some program to join two exe together. What do? Edit: The two project files do different things. For example, the project in VS2006 one sets up a server, and the project in VS2010 one grabs info on the user's OS. The code for the "server", I think, has a lot of dependencies and for some reason cannot convert to Visual c++ 2010. The code for "grabbing" requires some newer libraries and compiling options, and would not work if I port to 2006.

• How to make buttons in python/pygame?

  - by user1334014

  I'm making a game in pygame and on the first screen I want there to be buttons that you can press to (i) start the game, (ii) load a new screen with instructions, and (iii) exit the program. I've found this code online for button making, but I don't really understand it (I'm not that good at object oriented programming). If I could get some explanation as to what it's doing that would be great. Also, when I use it and try to open a file on my computer using the file path, I get the error sh: filepath :Permission denied, which I don't know how to solve. #load_image is used in most pygame programs for loading images def load_image(name, colorkey=None): fullname = os.path.join('data', name) try: image = pygame.image.load(fullname) except pygame.error, message: print 'Cannot load image:', fullname raise SystemExit, message image = image.convert() if colorkey is not None: if colorkey is -1: colorkey = image.get_at((0,0)) image.set_colorkey(colorkey, RLEACCEL) return image, image.get_rect() class Button(pygame.sprite.Sprite): """Class used to create a button, use setCords to set position of topleft corner. Method pressed() returns a boolean and should be called inside the input loop.""" def __init__(self): pygame.sprite.Sprite.__init__(self) self.image, self.rect = load_image('button.png', -1) def setCords(self,x,y): self.rect.topleft = x,y def pressed(self,mouse): if mouse[0] > self.rect.topleft[0]: if mouse[1] > self.rect.topleft[1]: if mouse[0] < self.rect.bottomright[0]: if mouse[1] < self.rect.bottomright[1]: return True else: return False else: return False else: return False else: return False def main(): button = Button() #Button class is created button.setCords(200,200) #Button is displayed at 200,200 while 1: for event in pygame.event.get(): if event.type == MOUSEBUTTONDOWN: mouse = pygame.mouse.get_pos() if button.pressed(mouse): #Button's pressed method is called print ('button hit') if __name__ == '__main__': main() Thank you to anyone who can help me.

• How can I programmatically get the connection status of OSX network services?

  - by BigBrainz

  In the OS X System Preferences, when I click on 'Network' I see a green dot by 'Ethernet', and red dots by 'AirPort' and 'FireWire'. This is because I turned off AirPort and FireWire, as I access networks and the Internet via Ethernet. I need to programmatically determine which of these network services displayed in System Preferences have green dots and which have red dots. For Ethernet and FireWire the displayed status is 'Connected' or 'Not Connected', and for AirPort the displayed status is 'On' or 'Off'. Perhaps other network services have other status labels. I have picked through all the plist files in '/Library/Preferences/SystemConfiguration', particularly 'preferences.plist' and 'NetworkInterfaces.plist'. I can get all sorts of information there, such as the Location set, network service order, proxy information (which is also important to my task), but I cannot find how to determine whether a given network service is on or off--the equivalent of having the green dot displayed. I have also tried using System Configuration framework, specifically the SCNetworkConnectionGetStatus function, but all I get are invalid connection statuses. Does anyone know how to actually retrieve this connection status information? Thanks.

• How do I daemonize an arbitrary script in unix?

  - by dreeves

  I'd like a daemonizer that can turn an arbitrary, generic script or command into a daemon. There are two common cases I'd like to deal with: I have a script that should run forever. If it ever dies (or on reboot), restart it. Don't let there ever be two copies running at once (detect if a copy is already running and don't launch it in that case). I have a simple script or command line command that I'd like to keep executing repeatedly forever (with a short pause between runs). Again, don't allow two copies of the script to ever be running at once. Of course it's trivial to write a "while(true)" loop around the script in case 2 and then apply a solution for case 1, but a more general solution will just solve case 2 directly since that applies to the script in case 1 as well (you may just want a shorter or no pause if the script is not intended to ever die (of course if the script really does never die then the pause doesn't actually matter)). Note that the solution should not involve, say, adding file-locking code or PID recording to the existing scripts. More specifically, I'd like a program "daemonize" that I can run like % daemonize myscript arg1 arg2 or, for example, % daemonize 'echo `date` >> /tmp/times.txt' which would keep a growing list of dates appended to times.txt. (Note that if the argument(s) to daemonize is a script that runs forever as in case 1 above, then daemonize will still do the right thing, restarting it when necessary.) I could then put a command like above in my .login and/or cron it hourly or minutely (depending on how worried I was about it dying unexpectedly). NB: The daemonize script will need to remember the command string it is daemonizing so that if the same command string is daemonized again it does not launch a second copy. Also, the solution should ideally work on both OS X and linux but solutions for one or the other are welcome. (If I'm thinking of this all wrong or there are quick-and-dirty partial solutions, I'd love to hear that too.)

• .NET Development of iPhone App with MonoTouch - which development environment?

  - by Click Ahead

  Hi All, I'm a .NET developer (C#) with several years developing Windows Mobile Apps. I would like to get into developing iPhone Apps and MonoTouch looks good based on reviews I've read. So I'm going to go with MonoTouch. My understanding is that I'll need a new Mac, but as it happens I also need a new PC for my .NET windows development. My question is should I (a) Purchase a Mac Book Pro and dual boot with Windows 7 (b) Purchase a Mac Pro and dual boot with Windows 7 (c) Purchase a good Dev PC and a slighlty less well spec'd Mac Book Pro or Mac Pro Bear in mind I'm only doing MonoTouch development with the Mac, most of my development (approx. 80% initially) will be done on the Windows side. My budget is approx. €3,000 / $4,000 and I'd like a good, fast development environment.It's purely for development so on the windows side installing SQL 2008/VS 2010/Office and on the OS X side installing MonoTouch. BTW - my budget excludes licensing for VS/MonoTouch/etc, I have a MonoTouch and MSDN license. Any opinions are greatly appreciated. I'm a newbie to Mac's !

• IE dynamic image caching issue?

  - by rdevitt

  I have an html page that is loading multiple iframes into which are embedded dynamic images created from a Tomcat server page (.jsp). This works as expected from Chrome and Firefox, but for some reason IE displays all of the images the same (as the first image). I've created an example: http://coupondiscounts.com/dev/jsImageTest.html jsImageTest.html -- This page simply loads 6 instances of the testImageFrame.html page in separate iframes one-at-a-time, using Javascript. testImageFrame.html -- This is the page loaded in all the iframes. It contains only a JavaScript block that writes out the current time and an img tag. The img is dynamically generated by a .jsp page on a different server. It should be a white box on a black background. In the box are the current time (from the Tomcat server using Java) and a randomly created double between 0 & 1. What happens (in IE): The page almost instantly loads four identical iframes. Depending on the speed of your machine, the JavaScript times may vary by a second or two. The images' times will all be the same as will be the random number. This holds true even for the last two iframes which are loaded 5 and 10 seconds after the others (using JavaScript setTimeout()). What should happen (as it does in Chrome and FF): The page loads the same 4 iframes, but the random numbers in the images will be different. The times in the images occasionally span a second as well. Anyone have a clue as to what's going on here? Is IE doing some strange caching? The image header has "no-cache," "no-store" and all that. I've tried it on IE6 and 7. You can use the "Next" button to create another iframe. In IE, the images are always the same. Notes: I don't really need iframes, just the images, but if I only use img tags, the problem appears in Chrome and FF as well. I also don't really need to load these iframes dynamically, I was just trying to abstract the issue further and allow a delayed load for the latter 2 images.

• Why does Perl lose foreign characters on Windows; can this be fixed (if so, how)?

  - by Alex R

  Note below how ã changes to a. NOTE2: Before you blame this on CMD.EXE and Windows pipe weirdness, see Experiment 2 below which gets a similar problem using File::Find. The particular problem I'm trying to fix involves working with image files stored on a local drive, and manipulating the file names which may contain foreign characters. The two experiments shown below are intermediate debugging steps. The ã character is common in latin languages. e.g. http://pt.wikipedia.org/wiki/Cão Experiment 1 Experiment 2 To get around my particular problem, I tried using File::Find instead of piped input.

• Weird Rails database errors

  - by Jason Swett

  I've had some trouble getting my Rails app to connect to PostgreSQL so I decided to just say screw it and use SQLite for now. (I'm using the tutorial here: http://guides.rubyonrails.org/getting_started.html) I started a BRAND NEW, fresh Rails app from this tutorial. When I visit my app in the browser after deleting public/index.html, I get this the first time: Please install the pg adapter: `gem install activerecord-pg-adapter` (no such file to load -- active_record/connection_adapters/pg_adapter) That's odd to me because I'm not mentioning PostgreSQL anywhere. Here's my databases.yml: # SQLite version 3.x # gem install sqlite3-ruby (not necessary on OS X Leopard) development: adapter: sqlite3 database: db/development.sqlite3 pool: 5 timeout: 5000 # Warning: The database defined as "test" will be erased and # re-generated from your development database when you run "rake". # Do not set this db to the same as development or production. test: adapter: sqlite3 database: db/test.sqlite3 pool: 5 timeout: 5000 production: adapter: sqlite3 database: db/production.sqlite3 pool: 5 timeout: 5000 To make things more confusing, I only get that "pg adapter" error on the first load. For every subsequent page request, I get this error: ActiveRecord::ConnectionNotEstablished So even though I removed all mention of PostgreSQL, I'm still getting errors. What could be going on?

• Make a PHP GET request from a PHP script and exit

  - by Abs

  Hello all, Is there something simpler than the following. I am trying to make a GET request to a PHP script and then exit the current script. I think this is a job for CURL but is there something simpler as I don't want to really worry about enabling the CURL php extension? In addition, will the below start the PHP script and then just come back and not wait for it to finish? //set GET variables $url = 'http://domain.com/get-post.php'; $fields = array( 'lname'=>urlencode($last_name), 'fname'=>urlencode($first_name) ); //url-ify the data for the GET foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; } rtrim($fields_string,'&'); //open connection $ch = curl_init(); //set the url, number of POST vars, POST data curl_setopt($ch,CURLOPT_URL,$url); curl_setopt($ch,CURLOPT_GET,count($fields)); curl_setopt($ch,CURLOPT_GETFIELDS,$fields_string); //execute GET $result = curl_exec($ch); //close connection curl_close($ch); I want to run the other script which contains functions when a condition is met so a simple include won't work as the if condition wraps around the functions, right?

• Chat app vs REST app - use a thread in an Activity or a thread in a Service?

  - by synic

  In Virgil Dobjanschi's talk, "Developing Android REST client applications" (link here), he said a few things that took me by surprise. Including: Don't run http queries in threads spawned by your activities. Instead, communicate with a service to do them, and store the information in a ContentProvider. Use a ContentObserver to be notified of changes. Always perform long running tasks in a Service, never in your Activity. Stop your Service when you're done with it. I understand that he was talking about a REST API, but I'm trying to make it fit with some other ideas I've had for apps. One of APIs I've been using uses long-polling for their chat interface. There is a loop http queries, most of which will time out. This means that, as long as the app hasn't been killed by the OS, or the user hasn't specifically turned off the chat feature, I'll never be done with the Service, and it will stay open forever. This seems less than optimal. Long question short: For a chat application that uses long polling to simulate push and immediate response, is it still best practice to use a Service to perform the HTTP queries, and store the information in a ContentProvider?

• How to find out style of NSUserNotification during run-time? Or force close an alert?

  - by Dmitri Shuralyov

  According to "OS X Mountain Lion Release Notes" (https://developer.apple.com/library/mac/#releasenotes/Cocoa/Foundation.html), "The user has ultimate control over what notifications are displayed, and the style (banner, alert, etc). There is no mechanism to override the user preferences." Even though all I want to do is "downgrade" from alert style to banner style... Fine. But can I at least find out whether a notification is of alert or banner style inside the didActivateNotification method? The reason I want to do that is to respond differently according to notification.activationType. When the alert is a banner (which is what I want), clicking its contents is the only possible action, and this both triggers didActivateNotification method and closes the notification banner. When the user chooses alert-style notifications, clicking the alert contents also generates didActivateNotification with the same value of notification.activationType, but it stays on screen instead of going away (it only goes away when the Action button is pressed). I don't want my app to trigger an action repeatedly for the same alert notification, in case the user clicks the content area of an alert notification. An alternative solution would be to force the alert notification bubble to dismiss when the user clicks its contents. Is this possible?

• mailto: anchor links unloading html5 video in Chrome

  - by Robin Pyon

  I have a very simple page with a <video> tag and an email anchor link: http://jsfiddle.net/6GquX/3/ Clicking the email link in Chrome (OS X 10.8 + Win7, 23.0.1271.97) invokes the beforeunloadchange event and causes the video to unload, which isn't the desired outcome. Curiously enough, if I let the video buffer a bit and then click the email link, the video keeps playing and doesn't unload. To my knowledge this only occurs in Chrome and I'm truly at a loss. Visiting any HTML5 video player site (videojs, flowplayer etc), starting a HTML5 video and then immediately simulating an email click with document.location.href = "mailto:[email protected]" in the dev console yields the same error. However, I'm inclined to think it's the way in which the video has been encoded as I'm unable to recreate the above with a video downloaded from YouTube's HTML5 player: http://jsfiddle.net/6GquX/4/ (source) 1. Is it possible that YouTube are encoding their videos in a particular way to combat this? 2. Are there any strategies / hacks I can employ to get around this?

• PHP include taking too long

  - by wxiiir

  I have a php file with around 100mb which is full of arrays (only arrays). I've made a script that includes this file (for processing), first it exhausted the default Xampp 128mb memory limit, i've raised it to 1024mb but it just takes forever and doesn't do anything. I'm sure the problem is being created by the sheer size of the file because i've tried removing all lines of code and just leaving the include and an echo for me to know when it finishes executing, and it does the same thing (which is taking forever), i've also tried to run the 100mb file in separate and same thing again. A 10mb file is taking forever as well but a similar 1mb file is almost instantly read and executed so the problem must be more than just the file size. I was avoiding using c++ for a simple project as this and would rather not to as php is easier for me and the task that will be executed doesn't need to benefit from the added speed that it would have if it had been done in c++ but if i have no luck in solving this problem i guess i'll have to. EDIT Reasons for not using a database: 1-Whoever made it didn't used a database and it will be pretty hard to store this in an organized database if i'm not able to do something with it first, like just reading it, copying parts from it or putting in memory or something. 2-I don't have experience working with databases as pretty much all stuff i've ever done in php didn't needed large amounts of stored data, 50kb at best, if i was thinking about a big project or huge chunks of data as this one, i definitely would, but i didn't made this mess to start with and now i have to undo it. 3-The logic for having to store a small portion of data like 10mb in hard drive when now every computer has pretty much enough ram to fit the whole OS in it is pretty much incomprehensible unless someone gives a good explanation about it, if i had to access a lot of said files simultaneously i would understand but like i said, this is a simple project, this is the only file that will be accessed at a given time this isn't even to make some kind of website, it's to run a few times and be done with it.

• Maximized MFC window has dead region at the top

  - by John Calsbeek

  I'm trying to make a MFC window fullscreen whenever it is maximized. This window is being used to draw OpenGL content. So far it works fine—it fills the entire screen with the exception of the taskbar—but there's a dead black region at the top of the screen, 62 pixels in height. It's pretty darn close to the height of the Windows 7 taskbar, but it pretty much stays the same regardless of if the taskbar is on autohide or on a different side of the screen. When I get a CWind::OnSize callback, the height that is given is 988, which is 62 pixels short of the actual screen height (1050). I've tried to manually set the window height to 1050 with SetWindowPos, I've tried to give Windows the screen dimensions in CWnd::OnGetMinMaxInfo, and I've tried to give the screen dimensions to glViewport instead of the 988 pixels that I'm being given. None of these seem to work. I'm accomplishing the fullscreening with a call to… ModifyStyle(0, WS_MINIMIZEBOX | WS_MAXIMIZEBOX | WS_SYSMENU | WS_CAPTION | WS_POPUP, 0); …in the SIZE_MAXIMIZED CWnd::OnSize callback, which works fine, except for this dead region. I don't know if it's an OpenGL thing or a Win32 thing or a MFC thing. The GetClientRect function for my window reports the false 988 height. The same OpenGL rendering code works fine in my Mac OS X build. Curiously enough, I have gotten the dead region to move around a bit when I play with the taskbar (autohiding it, moving it around the screen, etc.). I've gotten the dead area to shrink to about half—not sure if the other half went to the bottom of the window or not.

• What is causing this template-related compile error? (c++)

  - by Setien

  When I try to compile this: #include <map> #include <string> template <class T> class ZUniquePool { typedef std::map< int, T* > ZObjectMap; ZObjectMap m_objects; public: T * Get( int id ) { ZObjectMap::const_iterator it = m_objects.find( id ); if( it == m_objects.end() ) { T * p = new T; m_objects[ id ] = p; return p; } return m_objects[ id ]; } }; int main( int argc, char * args ) { ZUniquePool< std::string > pool; return 0; } I get this: main.cpp: In member function ‘T* ZUniquePool<T>::Get(int)’: main.cpp:12: error: expected `;' before ‘it’ main.cpp:13: error: ‘it’ was not declared in this scope I'm using GCC 4.2.1 on Mac OS X. It works in VS2008. I'm wondering whether it might be a variation of this problem: http://stackoverflow.com/questions/1364837/why-doesnt-this-c-template-code-compile But as my error output is only partially similar, and my code works in VS2008, I am not sure. Can anyone shed some light on what I am doing wrong?

• Picture.writeToStream() not writing out all bitmaps

  - by quickdraw mcgraw

  I'm using webview.capturePicture() to create a Picture object that contains all the drawing objects for a webpage. I can successfully render this Picture object to a bitmap using the canvas.drawPicture(picture, dst) with no problems. However when I use picture.writeToStream(fos) to serialize the picture object out to file, and then Picture.createFromStream(fis) to read the data back in and create a new picture object, the resultant bitmap when rendered as above is missing any larger images (anything over around 20KB! by observation). This occurs on all the Android OS platforms that I have tested 1.5, 1.6 and 2.1. Looking at the native code for Skia which is the underlying Android graphics library and the output file produced from the picture.writeToStream() I can see how the file format is constructed. I can see that some of the images in this Skia spool file are not being written out (the larger ones), the code that appears to be the problem is in skBitmap.cpp in the method void SkBitmap::flatten(SkFlattenableWriteBuffer& buffer) const; It writes out the bitmap fWidth, fHeight, fRowBytes, FConfig and isOpaque values but then just writes out SERIALIZE_PIXELTYPE_NONE (0). This means that the spool file does not contain any pixel information about the actual image and therefore cannot restore the picture object correctly. Effectively this renders the writeToStream and createFromStream() APIs useless as they do not reliably store and recreate the picture data. Has anybody else seen this behaviour and if so am I using the API incorrectly, can it be worked around, is there an explanation i.e. incomplete API / bug and if so are there any plans for a fix in a future release of Android? Thanks in advance.

• changes in main.xml are not reflected in the android app in netbeans

  - by nitish712

  I am new to android apps. I am using the netbeans 7.0.1 IDE to develop android apps. I have written the following code in the main java file: package com.test.helloworld; import android.app.Activity; import android.os.Bundle; import android.widget.TextView; public class helloworld extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); TextView t1=new TextView(this); t1.setText("hello world..!!!!"); setContentView(t1); } } This was working fine. I edited the main.xml file to display a textfield and button as follows: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/button_send"/> <EditText android:id="@+id/edit_message" android:layout_width="wrap_content" android:layout_height="wrap_content" android:hint="@string/edit_message"/> </LinearLayout> Of course I have added all the corresponding strings in strings.xml. But when I try to run my app these weren't displaying... :( . I mean the same string that was displayed previously was being displayed. Can anybody figure out what is the mistake? thanx...
