  • APNS: Not receving any feedback for registerForRemoteNotificationTypes: neither +/-

    - by vviji
    Hi, I have been trying to use the default code in the iPhone APNS documentation to generate a device token using registerForRemoteNotificationTypes() but without succes. Neither the didRegisterForRemoteNotificationsWithDeviceToken or the didFailToRegisterForRemoteNotificationsWithError is called. I had placed a UIAlert in both these methods- both did not appear. My iPhone is acceesing APNS using Wi/Fi using DHCP.(& am able to browse ) Is there any other setting that needs to to be done to genrate a device token? can someone post a working code which can be used to generate device token? Thanks, V

  • do-while loop in Python?

    - by Eye of Hell
    I need to emulate a do-while loop in a python. But, unfortunately, following straightforward code does not work: l = [ 1, 2, 3 ] i = l.__iter__() s = None while True : if s : print s try : s = i.next() except StopIteration : break print "done" Instead of "1,2,3,done" I have the following output: [stdout:]1 [stdout:]2 [stdout:]3 None['Traceback (most recent call last): ', ' File "test_python.py", line 8, in <module> s = i.next() ', 'StopIteration '] What can I do in order to catch 'stop iteration' excepton and break a while loop properly? Example why such thing may be needed. State machine: s = "" while True : if state is STATE_CODE : if "//" in s : tokens.add( TOKEN_COMMENT, s.split( "//" )[1] ) state = STATE_COMMENT else : tokens.add( TOKEN_CODE, s ) if state is STATE_COMMENT : if "//" in s : tokens.append( TOKEN_COMMENT, s.split( "//" )[1] ) else state = STATE_CODE # re-evaluate same line continue try : s = i.next() except StopIteration : break

  • PDO::fetchAll vs. PDO::fetch in a loop

    - by Byron
    Just a quick question. Is there any performance difference between using PDO::fetchAll() and PDO::fetch() in a loop (for large result sets)? I'm fetching into objects of a user-defined class, if that makes any difference. My initial uneducated assumption was that fetchAll might be faster because PDO can perform multiple operations in one statement while mysql_query can only execute one. However I have little knowledge of PDO's inner workings and the documentation doesn't say anything about this, and whether or not fetchAll() is simply a PHP-side loop dumped into an array. Any help?

  • Alternative Input Device(Midi) doesn't prevent Screen Saver in Winforms application

    - by DTig
    I have developed a c# winforms application whereby the user is providing input via a midi connected device. The user will go for long periods without using the keyboard or mouse. When I receive a midi message is there anything I can do to "tell" the system that this counts as user activity (ie key press). I don't want the screen saver or time lockouts to occur, if they are actively using the midi device. I think my request is different than other requests I've seen because they want to disable screen savers for the life of their application whereby I just want midi input I receive to count as user interactivity. Is there something I can call when I receive midi input to signify to the system user activity?

  • AJAX call in for loop won't return values to correct array positions

    - by Heilemann
    I need to get a range of pages using AJAX and put them into an array, where their given place in the array is equal to the i of a for loop (it's a caching-like function for blog pages, and the range of the for loop is entirely variable). I'm doing something akin to the following: var bongo = new Array(); for (i = 0; i < 10; i++) { jQuery.ajax({ type: "GET", url: http://localhost, data: queryString, success: function(request) { bongo[i] = request } }) } The problem is, that unless I add async: false to the .ajax options (which would make it... SJAX?), which causes the requests to basically pause the browser, going against what I'm trying to do, the i in the success callback will always end up being 11, whereas I of course want it to pour the returned data into each slot of the array from 0 to 10. I've tried replacing the line with this: bongo[i] = jQuery.ajax({ type: "GET", url: http://localhost, data: queryString }).responseText But that made no difference.

  • Break nested loop in Django views.py with a function

    - by knuckfubuck
    I have a nested loop that I would like to break out of. After searching this site it seems the best practice is to put the nested loop into a function and use return to break out of it. Is it acceptable to have functions inside the views.py file that are not a view? What is the best practice for the location of this function? Here's the example code from inside my views.py @login_required def save_bookmark(request): if request.method == 'POST': form = BookmarkSaveForm(request.POST) if form.is_valid(): bookmark_list = Bookmark.objects.all() for bookmark in bookmark_list: for link in bookmark.link_set.all(): if link.url == form.cleaned_data['url']: # Do something. break else: # Do something else. else: form = BookmarkSaveForm() return render_to_response('save_bookmark_form.html', {'form': form})

  • jQuery Star Rating plugin - select in callback causes infinite loop

    - by Ian
    Using the jQuery Star Rating plugin everything works well until I select a star rating from the rating's callback handler. Simple example: $('.rating').rating({ ... callback: function(value){ $.ajax({ type: "POST", url: ... data: {rating: value}, success: function(data){ $('.rating').rating('select', 1); } }); } }); I'm guessing this infinite loop occurs because the callback is fired after a manual 'select' as well. Once a user submits their rating I'd like to 'select' the average rating across all users (this value is in data returned to the success handler). How can I do this without triggering an infinite loop?

  • C Programming: malloc and free within a loop

    - by kouei
    Hi all, I just started out with C and have very little knowledge about performance issues with malloc() and free(). My question is as such: if I were to call malloc() followed by free() in a while-loop that loops for, say, 20 times, would it run slower compared to if I were to call free() outside the loop? I am actually using the first method to allocate memory to a buffer, read a string of variable length in a file, perform some string operation, and then clear the buffer after every iteration. If my method results in a lot of overhead then I'd like to ask for a better way for me to achieve the same results. Sorry for my bad English. Thanks and regards, K

  • Microsecond (or one ms) time resolution on an embedded device (Linux Kernel)

    - by ChrisDiRulli
    Hey guys, I have a kernel module I've built that requires at least 1 ms time resolution. I currently use do_gettimeofday() but I'm concerned that this won't work once I move my module to an embedded device. The device has a 180 Mz processor (MIPS) and the default HZ value in the kernel is 100. Thus using jiffies will only give me at best 10 ms resolution. That won't cut it. What I'd like to know is if do_gettimeofday() is based on the timer interrupt (HZ). Can it be guaranteed to provide at least 1 ms of resolution? Thanks!

  • Install multiple iPhone apps at once from Xcode to device

    - by Dimitris
    Supposing we have an Xcode iPhone project with 2 targets, is it possible to build and install both of them on the device with one click? Of course, I understand we will not be able to "build and run" both, but can we at least install them? And to extend this concept a bit a bit: are there any scripts to achieve the same thing but with multiple iPhone projects instead of multiple targets in one project? This would be useful when you want to load all your apps on a new development device and don't want to go through all your projects one by one and install.

  • Make VS 2008 Auto Deploy SQL Server CE 3.5 When Debugging on Windows Mobile 5.0 Device

    - by INTPnerd
    How do you make VS 2008 automatically install SQL Server CE 3.5 when debugging (F5) a CF app on a windows Mobile 5.0 device? VS used to do this automatically, but now it stopped and I don't know why. I have changed the structure of my solution and the projects, but it is still using SQL Server CE 3.5. It used to also install the Query Analyzer as well which was useful. I frequently uninstall all the programs on the device or do hard reboots so installing this manually is what I am trying to avoid.

  • Loop through text nodes inside a div

    - by crosenblum
    I am trying to do a text replace, but to do so, i need to loop through the text nodes of a div. Each Div upon clicking, loads via ajax it's appropriate content. But then I need to do text-replacing inside any of the text nodes inside there. My current code, after loading the ajax content, loops through all text nodes of the whole page, and therefore is too resource intensive. I have been looking for hours trying to find out how to both loop thru a div, and get the text nodes... and this has to work in firefox, google chrome and ie6. Any thoughts or suggestions?

  • Should one use < or <= in a for loop

    - by Eugene Katz
    If you had to iterate through a loop 7 times, would you use: for (int i = 0; i < 7; i++) or: for (int i = 0; i <= 6; i++) There are two considerations: performance readability For performance I'm assuming Java or C#. Does it matter if "less than" or "less than or equal to" is used? If you have insight for a different language, please indicate which. For readability I'm assuming 0-based arrays. UPD: My mention of 0-based arrays may have confused things. I'm not talking about iterating through array elements. Just a general loop. There is a good point below about using a constant to which would explain what this magic number is. So if I had "int NUMBER_OF_THINGS = 7" then "i <= NUMBER_OF_THINGS - 1" would look weird, wouldn't it.

I don't know why. This happens sometimes. So my question are: Is there any way Apache make connection loop? Is there a tool help me to monitor the connection? My question may not clear but I don't have any glue right now. Thanks

  • DOS Batch script loop

    - by Tom J Nowell
    I need to execute a command 100-200 times, so far my research indicates that I would either have to copy paste 100 copies of this command, OR use a FOR loop, but the for loop expects a list of items, hence I would need 200 files to operate on, or a list of 200 items, hence defeating the point. I would really not have to write a C program and go through the length of documenting why I had to write another program to execute my program for test purposes. Modification of my program itself is also no an option. So, given a command how would I execute it times via a DOS batch script?

  • Finding out whether a DirectInput device supports XInput (with mingw/gcc)

    - by Mr. Wonko
    I'm working on an input system, wrapping DirectInput and XInput. Currently XInput devices are enumerated twice, once as XInput and once as DirectInput (since they support both). How can I find out if a given DirectInput device also supports XInput? There is this MSDN page on the topic, but it requires wbemidl.h and wmsstd.h which aren't available in mingw/gcc (and for some reason I want to avoid msvc - probably by habit). I don't think blacklisting device names/guids is a good solution, but is there a better one? Thanks.

  • Consuming a USB HID device in Windows CE 6.0 using c#

    - by kersny
    I am working on an Embedded Windows CE project and am interested in accessing a USB HID device through one of its USB Host ports. All I really need to read are the raw HID spec packets. On a windows computer, I have a working program using hid.dll, but as far as I have researched, there is no equivalent on CE. I know there is the usbhid.dll, but I'm not sure if it is applicable for this situation. I would prefer not to write a kernel level driver, as I would like to do my coding in c#. Has anyone had experience consuming an HID device on Windows CE?

  • PHP Curl and Loop based on a numeric value

    - by danit
    Im using the Twitter API to collect the number of tweets I've favorited, well to be accurate the total pages of favorited tweets. I use this URL: http://api.twitter.com/1/users/show/username.xml I grab the XML element 'favorites_count' For this example lets assume favorites_count=5 The Twitter API uses this URL to get the favorties: http://twitter.com/favorites.xml (Must be authenticated) You can only get the last 20 favorties using this URL, however you can alter the URL to include a 'page' option by adding: ?page=3 to the end of the favorites URL e.g. http://twitter.com/favorites.xml?page=2 So what I need to do is use CURL (I think) to collect the favorite tweets, but using the URL: http://twitter.com/favorites.xml?page=1 http://twitter.com/favorites.xml?page=2 http://twitter.com/favorites.xml?page=3 http://twitter.com/favorites.xml?page=4 etc... Some kind of loop to visit each URL, and collect the Tweets and then output the cotents. Can anyone help with this: - Need to use CURL to authenticate - Collect the number of pages of tweets (Already scripted this) - Then use a loop to go through each page URL based on the pages value?

  • foreach loop from multiple arrays c#

    - by Mike
    This should be a simple question. All I want to know is if there is a better way of coding this. I want to do a foreach loop for every array, without having to redeclare the foreach loop. Is there a way c# projects this? I was thinking of putting this in a Collection...? Please, critique my code. foreach (TextBox tb in vert) { if (tb.Text == box.Text) conflicts.Add(tb); } foreach (TextBox tb in hort) { if (tb.Text == box.Text) conflicts.Add(tb); } foreach (TextBox tb in cube) { if (tb.Text == box.Text) conflicts.Add(tb); }

  • How to register a function in a driver code as its ISR

    - by CVS-2600Hertz-wordpress-com
    Following the feedback i got from: http://stackoverflow.com/questions/2683682/new-to-linux-kernel-driver-development/2683819 I have written a driver (.c file) by comparing it with an existing driver and "borrowing" heavily from its code. The driver is registered fine and init() and probe() are working fine. I am also able to access the peripheral device registers. :-) However i am a bit hazy about the IRQ/ISR. The peripheral-device is a input device and raises an interrupt on a GPIO pin. How do i move ahead from my current state ( init(), probe(), etc. ) to be able to handle the IRQ and execute my ISR function?? Many-Thanks in Advance
