  • Asynchronous database update in Django?

    - by Mark
    I have a big form on my site. When the users fill it out and submit it, most of the data just gets dumped to the database, and then they get redirected to a new page. However, I'd also like to use the data to query another site, and then parse the results. That might take a bit longer. It's not essential that the user sees these results right away, so I was wondering if it's possible to asynchronously call a function that will handle this, and then return an HttpResponse from my view like usual without making them wait? If so... how? Any particular libraries I should look at?

  • Change right-click context menu options in VS2008

    - by Mark Ursino
    When I right-click in my class library, I get some quick options to create things, like an Item from the popup list (New Item...), a User Control, etc. E.g. Now in my web app project, I'd like to be able to get the User Control listed in the right-click menu just like Component and Class, so I don't have to click New Item... then choose it from there. Is there a way to do this in the configuration? I can't seem to figure it out in VS.

  • Restoring web reference in Visual Studio 2008

    - by Mark Cheeseborough
    I had a web reference set in my VS2008 ASP.NET project, but due to some source control weirdness it is no longer listed in the project. I have the set of files in the Web References folder under my project. There's a .wsdl, .disco and several .datasource files. Is there any way to re-add this web reference through the existing files rather than using the "Add Web Reference" dialog?

  • After a period of time, nslookup still works, but pinging, and an auto-refeshed website, fails.

    - by Mark Hurd
    Contrary to this question this is for a dotted name (gw.localnet.au), and it doesn't happen straight away. Only after some period of time (quite a long time, possibly days). In fact this is for my ADSL router and its internal IP address which I have named within the router itself and in my Windows Server 2003 Domain Controller DNS Service. Specifically, localnet.au is a Active-Directory-backed primary domain. In fact, an ipconfig /flushdns may fix the problem, but only after a while (about the time it took me to type in this question :-) ). That doesn't explain the root cause though...

  • Use alternative browser with Subversion URLs

    - by Mark Howard
    We have subversion setup with http access through apache at http ://svn.local/ This provides access through svn clients and the standard svn repository browser. We also have a separate repository browser installed at http ://svn-browser.local/ (fisheye in this case). Is it possible to change the subversion/apache server so that browser requests are redirected to the subversion browser, but requests from svn clients go to the subversion server? Essentially, I'd like to use a single URL to identify a resource in both svn clients and the svn browser and be able to copy the url from a svn client into a web browser to have the enhanced functionality provided by the browser.

  • Removing Redundant Data from a List<T>

    - by Mark
    I have a List of objects which are ordered. I would like to remove redundant objects where redundant does not necessarily mean duplicate. Here is an example: List<Point> points = new List<Point> { new Point(0, 10), new Point(1, 12), new Point(2, 16), new Point(3, 16), new Point(4, 16), new Point(5, 13), new Point(6, 16), }; I am interested in removing the new Point(3, 16) entry because it doesn't provide useful information; I already know that the element at 2=16 and the element at 4=16. The information that 3=16 doesn't do me any good in my application (because I already have the bounds {2,4}=16), so I would like to remove that entry. I'd also like to not that I want to keep the 5th and 6th entry because there are not consecutive entries where Y=16. Is there a slick way to do this with linq?

  • How to set utf8 in the auto-generated PHP code of flash builder 4 ?

    - by Mark
    HI, PHP problem here (I think): I've just created a Flex (Flash Builder) project with a datagrid linked to a database - the database is all utf8. When I run the project using the auto-generated code in flex4, the non-English part comes like ????? while the English part comes fine. The auto-generated PHP code uses mysqli. I've tried: $this->connection->set_charset('utf8'); or mysqli_query($this->connection,"SET NAMES utf8"); I also tried writing the code myself (I'm not a PHP guy): mysql_query("set names utf8"); was fine - but that's mysql and not mysqli (that's an "i" after the mysql) and I want to use the auto-generated code... any help is appreciated.

  • Regex Remove Images with style tag from Html

    - by Mark Milford
    Hi I am new to Regex, however I decided it was the easiest route to what I needed to do. Basically I have a string (in PHP) which contains a whole load of HTML code... I want to remove any tags which have style=display:none... so for example <img src="" style="display:none" /> <img src="" style="width:11px;display: none" > etc... So far my Regex is: <img.*style=.*display.*:.*none;.* > But that seems to leave bits of html behind and also take the next element away when used in php with preg_replace.

  • Are PDO prepared statements sufficient to prevent SQL injection?

    - by Mark Biek
    Let's say I have code like this: $dbh = new PDO("blahblah"); $stmt = $dbh->prepare('SELECT * FROM users where username = :username'); $stmt->execute( array(':username' => $_REQUEST['username']) ); The PDO documentation says The parameters to prepared statements don't need to be quoted; the driver handles it for you. Is that truly all I need to do to avoid SQL injections? Is it really that easy? You can assume MySQL if it makes a difference. Also, I'm really only curious about the use of prepared statements against SQL injection. In this context, I don't care about XSS or other possible vulnerabilities.

  • Need Help with .NET OpenId HttpHandler

    - by Mark E
    I'm trying to use a single HTTPHandler to authenticate a user's open id and receive a claimresponse. The initial authentication works, but the claimresponse does not. The error I receive is "This webpage has a redirect loop." What am I doing wrong? public class OpenIdLogin : IHttpHandler { private HttpContext _context = null; public void ProcessRequest(HttpContext context) { _context = context; var openid = new OpenIdRelyingParty(); var response = openid.GetResponse(); if (response == null) { // Stage 2: user submitting Identifier openid.CreateRequest(context.Request.Form["openid_identifier"]).RedirectToProvider(); } else { // Stage 3: OpenID Provider sending assertion response switch (response.Status) { case AuthenticationStatus.Authenticated: //FormsAuthentication.RedirectFromLoginPage(response.ClaimedIdentifier, false); string identifier = response.ClaimedIdentifier; //****** TODO only proceed if we don't have the user's extended info in the database ************** ClaimsResponse claim = response.GetExtension<ClaimsResponse>(); if (claim == null) { //IAuthenticationRequest req = openid.CreateRequest(identifier); IAuthenticationRequest req = openid.CreateRequest(Identifier.Parse(identifier)); var fields = new ClaimsRequest(); fields.Email = DemandLevel.Request; req.AddExtension(fields); req.RedirectingResponse.Send(); //Is this correct? } else { context.Response.ContentType = "text/plain"; context.Response.Write(claim.Email); //claim.FullName; } break; case AuthenticationStatus.Canceled: //TODO break; case AuthenticationStatus.Failed: //TODO break; } } }

  • objective-c having issues with an NSDictioary object

    - by Mark
    I have a simple iPhone app that Im learning and I want to have an instance variable called urlLists which is an NSDictionary I have declared it like so: @interface MyViewController : UIViewController <UIPickerViewDataSource, UIPickerViewDelegate>{ IBOutlet UIPickerView *pickerView; NSMutableArray *categories; NSDictionary *urlLists; } @property(retain) NSDictionary *urlLists; @end and in the implementation: @implementation MyViewController @synthesize urlLists; ... - (void)viewDidLoad { [super viewDidLoad]; categories = [[NSMutableArray alloc] init]; [categories addObject:@"Sport"]; [categories addObject:@"Entertainment"]; [categories addObject:@"Technology"]; [categories addObject:@"Political"]; NSArray *objects = [NSArray arrayWithObjects:@"value1", @"value2", @"value3", @"value4", nil]; urlLists = [NSDictionary dictionaryWithObjects:objects forKeys:categories]; for (id key in urlLists) { NSLog(@"key: %@, value: %@", key, [urlLists objectForKey:key]); } } ... @end And, this all works up to here. I have added a UIPicker to my app, and when I select one of the items, I want to Log the one picked and its related entry in my dictionary. -(void) pickerView:(UIPickerView *)thePickerView didSelectRow:(NSInteger)row inComponent:(NSInteger) component { for (id key in self.urlLists) { NSLog(@"key: %@, value: %@", key, [urlLists objectForKey:key]); } } but I get the old EXC_BAD_ACCESS error... I know Im missing something small, but what? Thanks

  • TargetInvocationException?

    - by Mark
    Why would these lines of code cause that exception private Dispatcher dispatcher = null; public DownloadManager(Dispatcher dispatcher = null) { this.dispatcher = dispatcher ?? Dispatcher.CurrentDispatcher; } When the DownloadManager is instantiated in the XAML like <Window.DataContext> <c:DownloadManager /> </Window.DataContext> ?

  • How can I quickly sum all numbers in a file?

    - by Mark Roberts
    I have a file which contains several thousand numbers, each on it's own line: 34 42 11 6 2 99 ... I'm looking to write a script which will print the sum of all numbers in the file. I've got a solution, but it's not very efficient. (It takes several minutes to run.) I'm looking for a more efficient solution. Any suggestions?

  • How to add an additional field to a queryset?

    - by Mark
    I've got a list of affiliates (users who have referred someone to the site): affiliates = User.objects.annotate(referral_count=Count('referrals')).filter(referral_count__gt=0) And a count of the number of users each affiliate has referred within a time frame: new_users = User.objects.filter(date_joined__gt=sd, date_joined__lte=ed) new_referrals = User.objects.filter(referrals__user__in=new_users).annotate(referral_count=Count('referrals')) How can I do something like new_referrals['affiliate.username'].referral_count from within my template? Note that this is not just a syntax issue, I also need to index new_referrals somehow so that I'm able to do this. Either this, or if I can somehow add a new_referral_count to the first query, that'd work too.

  • Remote stream multiple files in SOLR

    - by Mark
    I want to use SOLR's remote-streaming facility to extract and index the content of files. This works fine if I pass stream.file=xxx as a parameter to the http GET method. However, I have a lot of these, and want to batch them up (i.e. not have to have a GET per file). Is there a way I can do this in SOLR? e.g. I'd like to be able to POST some xml like this: <add> <doc stream_file="filename"> <field name="id">123</field> </doc> <doc>...

  • How can I detect if a string contains punctuation marks at the end?

    - by Sheehan Alam
    Lets assume I have the string: "Hello I like your shoes #today...!" I am tokenizing the string by spaces: return [string componentsSeparatedByString:@" "]; So my array contains: Hello I like your shoes #today...! I want to focus on "#today...!" any word that has a # in the prefix I am changing the font color. How can I make sure that only "#today" has its font color changed? I would basically like to figure out if a word has a punctuation mark at the end, and change the color for characters before the punctuation mark.

  • jquery toggle+paginate+multiple instances

    - by mark
    Hi, I'm a jquery newbie - wanted to ask what might be the best strategy for achieving what I am after as I think it uses a mix of jquery functions : If list of items exceeds 5 items a 'more' link appears which when toggled will reveal the rest of the items. If items list is 5 or less no 'more' link is shown. Hide button also at bottom of long full revealed list. (perhaps this is toggle+pagination?) And then also that this can be used in multiple instances, as it is for multiple category menu's.(to be used in typical indexhibit websites structure like http://mikeyburton.com/) link 1 link 2 link 3 link 4 link 5 link 6 link 7 link 8 more Any help or links greatly appreciated.

  • How can I identify whether a browser/reader is being used by someone who is visually impaired?

    - by Mark Brittingham
    I have to provide a 508-compliant version of a page for the visually impaired and it isn't practical to just modify the page. Thus, I have created a new "reader-compatible" version of the page for the handicapped. The question is how I can tell if someone is using a reader rather than a standard browser? Is there a "header" or "useragent" value typically used by these non-standard browsers that I can look for? Thanks in advance!

  • iPhone: How can you draw a piece of an image

    - by Mark
    Code sample - (void)drawRect:(CGRect)rect { [super drawRect:rect]; CGContextRef context = UIGraphicsGetCurrentContext(); CGContextSaveGState(context); CGContextTranslateCTM(context, 0, self.frame.size.height); CGContextScaleCTM(context, 1.0, -1.0); CGContextDrawImage(context, CGRectMake(0.0, 0.0, self.frame.size.width, self.frame.size.height), [UIImage imageNamed:@"sample.png"].CGImage); CGContextRestoreGState(context); } ================ I would like to copy a certain rect within an image to the context, so not the entire image is drawn but just a piece of the image. Does anyone have a solution for this? I can't find anything on google nor the documentation. I know there are alternatives like: 1. Create a UIView with clipping and then just position the UIImageView within it. 2. Create the UIImageView within the UIScrollView and use content offset. But I think those are lame...
