  • Object C casting

    - by ct2k7
    Hi, I'm trying to cast this statement: [self handError:noConnectionError]; basically, this statement is in a class, which is not the app delegate, but is the .m file of a view, specifically a view after uitableview, which contains its own uiviewtable. The warning that statement gives me is that the error produced may not be apparent to the UIView (view control container).

  • changing ASP.NET tag formatting

    - by Steven
    When I drag a Label control to my document, I get the following code : <asp:Label ID="Label1" runat="server" text="Label"></asp:Label> I prefer my code to look like the following instead : <asp:Label ID="Label1" runat="server" Text="Label" /> How can I get .NET to do this by default? I looked in Tools - Options - Text Editor, where you'd expect to find it, but I couldn't find anything relevant there.

  • Public Wildcard Domain Name To Resolve To 127.0.0.1

    - by Rahul
    Is anyone aware of a public wildcard domain name that resolves to IP address 127.0.0.1. For example if I wanted to test a URL locally such as mywebsite.localhost.com or example.localhost.com but I don't have control of DNS settings (hosts file or whatever) then I would use this public DNS to resolve to 127.0.0.1. It needs to be wildcarded so that no matter whatever comes before localhost.com it still resolves to 127.0.0.1.

  • How to record / capture audio with RecordControl on Java ME, SE K770i

    - by tomaszs
    I want to record sound on my Java ME App on K770i. So I used this: http://java.sun.com/javame/reference/apis/jsr135/javax/microedition/media/control/RecordControl.html example of RecordControl in my code. It goes like this: import java.util.Vector; import javax.microedition.lcdui.Choice; import javax.microedition.lcdui.Command; import javax.microedition.lcdui.CommandListener; import javax.microedition.lcdui.Display; import javax.microedition.lcdui.Displayable; import javax.microedition.lcdui.List; import javax.microedition.media.Manager; import javax.microedition.media.MediaException; import javax.microedition.midlet.MIDlet; import java.io.*; import javax.microedition.lcdui.*; import javax.microedition.media.*; import javax.microedition.media.control.*; import javax.microedition.midlet.*; import javax.microedition.rms.*; (...) try { // Create a Player that captures live audio. Player p = Manager.createPlayer("capture://audio"); p.realize(); // Get the RecordControl, set the record stream, // start the Player and record for 5 seconds. RecordControl rc = (RecordControl)p.getControl("RecordControl"); ByteArrayOutputStream output = new ByteArrayOutputStream(); rc.setRecordStream(output); rc.startRecord(); p.start(); Thread.currentThread().sleep(5000); rc.commit(); p.close(); } catch (IOException ioe) { } catch (MediaException me) { } catch (InterruptedException ie) { } But unfortunately when I try to build it, it tells me: *** Creating directories *** *** Compiling source files *** ..\src\example\audiodemo\AudioPlayer.java:121: cannot find symbol symbol : class RecordControl location: class example.audiodemo.AudioPlayer RecordControl rc = (RecordControl)p.getControl("RecordControl"); ^ ..\src\example\audiodemo\AudioPlayer.java:121: cannot find symbol symbol : class RecordControl location: class example.audiodemo.AudioPlayer RecordControl rc = (RecordControl)p.getControl("RecordControl"); ^ 2 errors So my question is: why there is no RecordControl class if in documentations it is written this class should be there. Or is there other method to record / capture audio from microfone in Java ME of Sony Ericsson? How do you record sound?

    - by Rachel Martin
    I have a DateTime stored in UTC time that I'd like to display to the user in their local time from within a GridView control.

  • Use SVN Revision to label build in CCNET

    - by hitec
    I am using CCNET on a sample project with SVN as my source control. CCNET is configured to create a build on every check in. CCNET uses MSBuild to build the source code. I would like to use the latest revision number to generate AssemblyInfo.cs while compiling. How can I retrieve the latest revision from subversion and use the value in CCNET? Edit: I'm not using NAnt - only MSBuild.

  • svn cat after svn del

    - by René Nyffenegger
    I have inadvertently svn-deleted a file with svn del --targets del.txt. Now, I'd like to recover that file with svn cat myPreciousFile.txt@4130 > myPreciousFile.txt, but svn gives me a warning that myPreciousFile.txt is not under version control. A svn cat -r 4130 myPreciousFile.txt > myPreciousFile.txt didn't work, either. Can someone please tell me how I'd go about recovering this file again?

  • Tabs for a ASP.NET website

    - by user102533
    I would like to add tabs for my website and I understand I can use the tab control in the AJAX toolkit or I can choose to go with JQuery UI tabs. Each tab would need to load a separate asp.net page and I need to customize the tabs to look slick. Any thoughts on what approach I can use?

  • Enterprise Architect Communication Diagrams question

    - by devoured elysium
    I want to achieve something like this in Enterprise Architect's Communication Diagrams: start() ---------------- 1. create() ------------ ------------> | RGController | ---------------> | U : User | ---------------- ------------ But I am facing 2 problems: a) it seems I have to always make a connection between 2 objects (I can't have the start() message just come out of nowhere, like I'd want). b) I can't control the numbering as I'd want. Is there any way I could just set the numbering by myself?

  • How can I swap WCF deserializer from configuration

    - by JohnIdol
    I have a problem with WCF deserialization where the client hangs on the response for more than a minute. I'd like to try to swap different deserializers and see if it affects the behavior. Can I swap in/out DataContract/Xml serializers (are there any others?) from configuration, and if so can I do that with any binding, or is that out of control once the service reference is imported? Any help appreciated!

  • How to show percentage of 'memory used' in a win32 process?

    - by pj4533
    I know that memory usage is a very complex issue on Windows. I am trying to write a UI control for a large application that shows a 'percentage of memory used' number, in order to give the user an indication that it may be time to clear up some memory, or more likely restart the application. One implementation used ullAvailVirtual from MEMORYSTATUSEX as a base, then used HeapWalk() to walk the process heap looking for additional free memory. The HeapWalk() step was needed because we noticed that after a while of running the memory allocated and freed by the heap was never returned and reported by the ullAvailVirtual number. After hours of intensive working, the ullAvailVirtual number no longer would accurately report the amount of memory available. However, this method proved not ideal, due to occasional odd errors that HeapWalk() would return, even when the process heap was not corrupted. Further, since this is a UI control, the heap walking code was executing every 5-10 seconds. I tried contacting Microsoft about why HeapWalk() was failing, escalated a case via MSDN, but never got an answer other than "you probably shouldn't do that". So, as a second implementation, I used PagefileUsage from PROCESS_MEMORY_COUNTERS as a base. Then I used VirtualQueryEx to walk the virtual address space adding up all regions that weren't MEM_FREE and returned a value for GetMappedFileNameA(). My thinking was that the PageFileUsage was essentially 'private bytes' so if I added to that value the total size of the DLLs my process was using, it would be a good approximation of the amount of memory my process was using. This second method seems to (sorta) work, at least it doesn't cause crashes like the heap walker method. However, when both methods are enabled, the values are not the same. So one of the methods is wrong. So, StackOverflow world...how would you implement this? which method is more promising, or do you have a third, better method? should I go back to the original method, and further debug the odd errors? should I stay away from walking the heap every 5-10 seconds? Keep in mind the whole point is to indicate to the user that it is getting 'dangerous', and they should either free up memory or restart the application. Perhaps a 'percentage used' isn't the best solution to this problem? What is? Another idea I had was a color based system (red, yellow, green, which I could base on more factors than just a single number)

  • Getting the source .rst file path in Sphinx extension

    - by Mikko Ohtamaa
    I am writing a Sphinx extension and I need to know the document page source code file system path (.rst file location) to extract some version control system information of it. How can I get this information in my event handler / which event handler I should use? Example: # This package may contain traces of nuts def on_html_page_context(app, pagename, templatename, context, doctree): import ipdb ; ipdb.set_trace() if doctree: print doctree.source def setup(app): app.require_sphinx('1.0') app.connect('html-page-context', on_html_page_context)

    Is it possible to exclude specific files (*.ai, *.psd) when pushing to certain repositories with GIT? My need comes from trying to use GIT for both version control and deployment to Heroku. If I include my graphic assets in the deploy, they slug size is larger than desired. However, I do need to include all project files in my main github repository. Thanks, Kevin

  • How to share memory buffer across sessions in Django?

    - by afriza
    I want to have one party (or more) sends a stream of data via HTTP request(s). Other parties will be able to receive the same stream of data in almost real-time. The data stream should be accessible across sessions (according to access control list). How can I do this in Django? If possible I would like to avoid database access and use in memory buffer (along with some synchronization mechanism)

  • What are the types and inner workings of a query optimizer?

    - by Frank Developer
    As I understand it, most query optimizers are cost-based. Some can be influenced by hints like FIRST_ROWS(). Others are tailored for OLAP. Is it possible to know more detailed logic about how Informix IDS and SE's optimizers decide what's the best route for processing a query, other than SET EXPLAIN? Is there any documentation which illustrates the ranking of SELECT statements? I would imagine that "SELECT col FROM table WHERE ROWID = n" ranks 1st. What are the rest of them?.. If I'm not mistaking, Informix's ROWID is a SERIAL(INT) which allows for a max. of 2GB nrows, or maybe it uses INT9 for TB's nrows?.. However, I think Oracle uses HEX values for ROWID. Too bad ROWID can't be oftenly used, since a rows ROWID can change. So maybe ROWID is used by the optimizer as a counter? Perhaps, it could be used for implementing the query progress idea I mentioned in my "Begin viewing query results before query completes" question? For some reason, I feel it wouldn't be that difficult to report a query's progress while being processed, perhaps at the expense of some slight overhead, but it would be nice to know ahead of time: A "Google-like" estimate of how many rows meet a query's criteria, display it's progress every 100, 200, 500 or 1,000 rows, give users the ability to cancel it at anytime and start displaying the qualifying rows as they are being put into the current list, while it continues searching?.. This is just one example, perhaps we could think other neat/useful features, the ingridients are more or less there. Perhaps we could fine-tune each query with more granularity than currently available? OLTP queries tend to be mostly static and pre-defined. The "what-if's" are more OLAP, so let's try to add more control and intelligence to it? So, therefore, being able to more precisely control, not "hint-influence" a query is what's needed and therefore it would be necessary to know how the optimizers logic is programmed. We can then have Dynamic SELECT and other statements for specific situations! Maybe even tell IDS to read blocks of indexes nodes at-a-time instead of one-by-one, etc. etc.

  • What are useful functions for drawing text (MFC)?

    - by kobac
    I'm creating a line chart control, and I need to write (or better say draw) the axis names and axis values. I found DrawText and TextOut functions, but the text they show is flickering and don't know how to set the font and text orientation (I will need vertical text orientation as well as horizontal). Are there any other functions you could recoommend or how to use these stated above and get the results I need? Thanks in advance. Cheers.
