  • Remaining time of QTimer

    - by Exa
    In one of my projects I am working with a QTimer and I wonderer whether it is possible to get the remaining time of a QTimer in order to let the user know "Time until next timeout: 10 secs" or something like that... Is that possible? If not so, has anyone good ideas for how to realize that? Maybe I got to write my own Timer...

    I want PHP to randomly create a multi-dimensional array by picking a vast amount of items out of predefined lists for n times, but never with 2 times the same.

I tried and all i got was the scrambling but there were always doubles :s

  • How to intercept 401 from Forms Authentication in ASP.NET MVC?

    - by Jiho Han
    I would like to generate a 401 page if the user does not have the right permission. The user requests a url and is redirected to the login page (I have deny all anonymous in web.config). The user logs in successfully and is redirected to the original url. However, upon permission check, it is determined that the user does not have the required permission, so I would like to generate a 401. But Forms Authentication always handles 401 and redirects the user to the login page. To me, this isn't correct. The user has already authenticated, the user just does not have the proper authorization. In other scenarios, such as in ajax or REST service scenario, I definitely do not want the login page - I need the proper 401 page. So far, I've tried custom Authorize filter to return ViewResult with 401 but didn't work. I then tried a normal Action Filter, overriding OnActionExecuting, which did not work either. What I was able to do is handle an event in global.asax, PostRequestHandlerExecute, and check for the permission then write out directly to response: if (permissionDenied) { Context.Response.StatusCode = 401; Context.Response.Clear(); Context.Response.Write("Permission Denied"); Context.Response.Flush(); Context.Response.Close(); return; } That works but it's not really what I want. First of all, I'm not even sure if that is the right event or the place in the pipeline to do that. Second, I want the 401 page to have a little more content. Preferably, it should be an aspx page with possibly the same master page as the rest of the site. That way, anyone browsing the site can see that the permission is denied but with the same look and feel, etc. but the ajax or service user will get the proper status code to act on. Any idea how this can be achieved? I've seen other posts with similar requests but didn't see a solution that I can use. And no, I do not want a 403.

  • Comet without AJAX

    - by Carl Whalley
    Suppose I only had the regular J2SE http libraries but wanted to write a client for comet, say in Android etc, but not limited to that, i.e. not using a WebView. Since there's no browser I'm assuming you'd have to open the long term connections yourself ... is this feasible?

  • ASP.NET, JQuery - Sharing regular expressions

    - by Steve
    If you have a fair number of regular expressions used by both client (javascript) and server side code (C#, vb.net) and want to store them in one place to avoid duplication, where do you store them? I could use registerscript and write out the regex as strings, but just wondering if there is something more elegant.

  • Check on null reference

    - by Neir0
    Hello, i have the follow code: searchResults.SearchResultCollection.Add( new SearchResult() { Header = HttpUtility.HtmlDecode( htmlDocument.DocumentNode .SelectSingleNode(initialXPath + "h3") .InnerText), Link = HttpUtility.HtmlDecode( htmlDocument.DocumentNode .SelectSingleNode(initialXPath + "div/cite") .InnerText) } ); Sometimes htmlDocument.DocumentNode.SelectSingleNode(....) returns null and my application crashed with NullReferenceException. Ofcourse i can write code which check returned value on null reference but then code will be overly verbose. What is graceful way to do that?

  • How do I make nested options for plugins in jQuery

    - by Oscar Godson
    I know how to do plugins, but how do I do nested options like: var defaults = { spacing:10, shorten_to:50, from_start:0, from_end:2, classes: { test:'testing' } }; i know that isn't right, i just dont know how to write the proper syntax when I want to do something like this: $('#breadcrumbs').breadcrumbs({classes{test:'new_example'},spacing:12}) other suggestions are welcome, im in need of the ability to custom class names and there are 7, so rather than making something like test_class, example_class, etc id like it cleaner and neater like the example above.

    - by Bob
    What is the preffered method for creating a byte array from an input stream? Here is my current solution with .NET 3.5. Is it still a better idea to read and write chunks of the stream? Stream s; byte[] b; using (BinaryReader br = new BinaryReader(s)) { b = br.ReadBytes(s.Length); }

    I want to be able to read events from a MIDI file in Python. I have looked for libraries, but can't find one that works with my MIDI file in windows.

  • ArcObjects: Is buffering a point faster than buffering a line / polyline?

    - by Quigrim
    I can write my code logic to either buffer a polyline or to buffer the to and from point of the polyline. Working with the points will be easier, so it is the preferred way. Logically my reasoning tells me that buffering a point will be faster as it will always be a perfect circle. But will buffering 2 points still be faster than buffering 1 polyline? My gut says yes. Any comments?

  • How to manage orientation lock in android?

    - by pixel
    I want to create checkbox in my preference Activity that allows user to toggle orientation change. In similar questions people write only about complete orientation lock (by overriding onConfigurationChanged method or adding configChanges in AndroidManifest.xml) or orientation enforcing ( by setRequestedOrientation ). Is there a way to toggle orientation lock?

  • General RewriteRule for many undefined parameters in URL

    - by FedericoBiccheddu
    I'm trying to write a rule to make that one can generalize, since multiple pages to pass the values are different. Right now I could do: RewriteRule ^forum/([^/]{1,255})/([\+]{1})/((([a-z]+)([_]{1})([a-zA-Z0-9]+)([/]?))+)$ forum.php?name=$1&$5=$7 [L] To address such as: Nome+del+Forum/+/page_1/action_do Should return: forum.php?name=Nome+del+Forum&page=1&action=do Instead, take only the last parameter (in this case action=do): forum.php?name=Nome+del+Forum&action=do How can I fix? Thanks in advance!

  • Passing variables to functions

    - by Faken
    A quick question: When i pass a variable to a function, dose the program make a copy of that variable to use in the function? If it dose and I knew that the function would only read the variable and never write to it, is it possible to pass a variable to the function without creating a copy of that variable or should I just leave that up to the compiler optimizations to do that automatically for me?
