  • android google maps my location

    - by windblow
    I have google maps activity where i would like to get my location but im facing NullPointerException... locManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); locManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, this); Location location = locManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER); System.out.println("loaded4"); myPoint = new GeoPoint((int)(location.getLatitude()*1E6),(int)(location.getLongitude()*1E6)); System.out.println("loaded5"); I am able to get "loaded4" but not "loaded5" So NullPointer cause is between them. I also tried to use GPS_PROVIDER but it didnt work out. Yes i have all permissions in manifest. Map is able to load in if im not searhing for my loacation. Is it possible its NullPointer because before that i load some other coordinates in same class ? Maybe its emulator fault ? I can give extended code if needed. Using source from http://www.chupamobile.com/tutorial/details/53

  • Problem generating GET url

    - by Bruce
    I am working on Java. I am calling a GET url on my own machine using Java. Here is the url string with the arguments. listen.executeUrl("http://localhost/post_message.php?query_string="+str); I am taking str as user input. BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); System.out.print("Enter query: "); str = br.readLine(); How do I encode str into GET argument. For eg. str -> test query url -> http://localhost/post_message.php?query_string=test%20query

  • Matching Line Boundaries in a Regular Expression (Pattern.MULTILINE/(?m)) is broken in Java?

    - by Mister M. Bean
    The example on http://www.exampledepot.com/egs/java.util.regex/Line.html gives false for me twice but should'nt! Why? CharSequence inputStr = "abc\ndef"; String patternStr = "abc$"; // Compile with multiline enabled Pattern pattern = Pattern.compile(patternStr, Pattern.MULTILINE); Matcher matcher = pattern.matcher(inputStr); boolean matchFound = matcher.find(); // true // Use an inline modifier to enable multiline mode matchFound = pattern.matches(".*abc$.*", "abc\r\ndef"); // false System.out.println(matchFound); // false matchFound = pattern.matches("(?m).*abc$.*", "abc\r\ndef"); // true System.out.println(matchFound);// false !!!!!

  • XMLHttpRequest progressive download?

    - by StackedCrooked
    Just for fun I was creating a JavaScript console for controlling my PC. It involves a small webserver that takes command strings and forwards those to the system using popen calls (to be more specific popen4 on a Ruby mongrel server). The stdout channels are redirected to the http response. The problem is that the response only arrives once the entire contents of stdout has been sent. This is ok for small commands, but not for a command like find / which lists all the files in the system. In such situations it would be nice to have the results shown progressively in the webview (just like in the regular terminal). I thought that using XMLHttpRequest synchronously might result in progressive downloading, but it doesn't seem so. Is there any way to make it work?

  • Lock thread using somthing other than a object

    - by Scott Chamberlain
    when using a lock does the thing you are locking on have to be a object. For example is this legal static DateTime NextCleanup = DateTime.Now; const TimeSpan CleanupInterval = new TimeSpan(1, 0, 0); private static void DoCleanup() { lock ((object)NextCleanup) { if (NextCleanup < DateTime.Now) { NextCleanup = DateTime.Now.Add(CleanupInterval); System.Threading.ThreadPool.QueueUserWorkItem(new System.Threading.WaitCallback(cleanupThread)); } } return; } EDIT-- From reading SLaks' responce I know the above code would be not valid but would this be? static MyClass myClass = new MyClass(); private static void DoCleanup() { lock (myClass) { // } return; }

  • C# Container Class

    - by Jamie
    I'm building a game in c# which allows you to script your own level, although I have come across a bit of a thought. I have a base class called "World" as an object. This was made with a simple: class World { However, when the user is scripting their level, all of the game objects will be contained in the world object. I want them to be able to do something on the lines of: World.ParentObjectName.ParentObjectProperty = "abc"; I know that the System.Windows.Forms.Panel and other classes are like containers and can have objects in them and be accessed in that kind of way... my question is how can I make a class which is like a container in which I can add objects to, and then access them with a World.ObjectName I have tried class World : System.Collections.CollectionBase, but with this method, I have to keep typing World.Item("ObjectName") Can anyone help? Thanks!

  • Windows XP: Have my program run in kernel mode?

    - by Kalamari
    I'm currently learning about the different modes the Windows operating system runs in (kernel mode vs. user mode), device drivers, their respective advantages and disadvantages and computer security in general. I would like to create a practical example of what a faulty device driver that runs in kernel mode can do to the system, by for example corrupting memory used for critical OS-processes. How can I execute my code in kernel mode instead of user mode, directly? Do I have to write a dummy device driver and install it to do this? Where can I read more about kernel and user mode in Windows? I know the dangers of this and will do all of the experiments on a virtual machine running Windows XP only

    Private Sub btnWord_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnWord.Click Dim Inputter As String Dim Words As String = "" Do Inputter = InputBox("Enter word", "Enter Word") If Inputter <> String.Empty Then lstDisplay.Items.Add(Inputter) Word += Inputter.Substring(0, 1) End If Loop Until Inputter <> String.Empty ' SOMETHING GOES HERE!!!!!' lstDisplay.Items.Add("---") lstDisplay.Items.Add(Word) End Sub Here is how it works, when you click the button it displays an input box so for example type in "CAT". But I can't figure out how to get it to do C (newline) A (newline) T (newline) within the listbox. Please help! C A T - CAT

  • Print an EObject ?

    - by tul
    I am writing some eclipse emf code and would like to print the content of an EObject (not store it to disk). Here is what I try: public static void print(EObject obj) { Resource eResource = obj.eResource(); try { eResource.save(System.out, null); } catch (IOException e) { e.printStackTrace(); } } but that gives a NullPointerException. I have tried this instead: public static void print(EObject obj) { ResourceSet resourceSet = new ResourceSetImpl(); resourceSet.getResourceFactoryRegistry().getProtocolToFactoryMap() .put("*", new XMIResourceFactoryImpl()); Resource resource = resourceSet.createResource(URI.createURI("dummyfile.xml")); resource.getContents().add(obj); try { resource.save(System.out, null); } catch (IOException ioe) { ioe.printStackTrace(); } } This works, but is it not possible to print to screen without specifying a dummy URI??

  • Java2D: if statement doesn`t work with java.awt.Color

    - by DarkSun
    I have a getPixelColour function: Color getPixelColor(int x, int y) { if(mazeImage == null) System.out.println(":("); int pixel = mazeImage.getRGB(x, y); int red = (pixel & 0x00ff0000) >> 16; int green = (pixel & 0x0000ff00) >> 8; int blue = pixel & 0x000000ff; return new Color(red,green,blue); } For example a pixel is black, and System.out.println(getPixelColor(x,y) + " " + Color.BLACK); writes "java.awt.Color[r=0,g=0,b=0] java.awt.Color[r=0,g=0,b=0]" But getPixelColor(x,y) == Color.BLACK return false. What's wrong with it?

  • Mac OS X: getting names of changed/written files

    - by Patrick
    I remember having a command line tool on an older Mac OS X version (Tiger?) that told me the name of every file that was written to (or read) by any process on the system. It used fseventd (? or something like that). Is there something like that for the newest Mac OS X (10.6)? It should be run in a terminal window and then I can use the system as normal. Let's say I type cat /etc/passwd, the output of that program would be similar to /bin/cat /etc/passwd I can't use lsof because I can't get the timing right. Is this clear or do you need more information?

  • Books on data-intensive enterprise integration patterns

    - by Tristan
    I'm trying to understand design patterns used by data-intensive enterprise applications. A classic example is the financial industry, where system must consume, analyze, and execute on real-time financial data while providing information and configuration options to a broad set of traders and analysts. One can imagine similar system in airlines, major supply chain operations, and utility providers. Are there good books that provide and inside view of how these systems work? Enterprise Integration Patterns is one example, but I'm looking for something with more real-world applications, particularly in finance.

  • Microsoft Enterprise Logging Application Block - Reading Log File

    - by Or A
    Hi, I'm using MS log application block for logging my application event into a file called app-trace.log which located on the c:\temp folder. I'm trying to find the best way to read this file at runtime and display it when the user asks for it. now i have 2 issues: it seems that this kind of feature is not supported by the framework, hence i have to write this reader myself. am i missing something here? is there any better way of getting this data (w/o buffering it in the memory or saving it into another file). if i'm taking the only alternative that left for me, and implementing the reader myself, when i'm tring to do: System.IO.FileStream fs = new System.IO.FileStream(@"c:\temp\app-trace.log", FileMode.Open, FileAccess.Read); i'm getting "File being used by another process c#", probably the file is locked by the application block. is there any way to access and read it anyhow? Thank

  • HP LaserJet 1515: Disable "refill" warning

    - by Pekka
    I have a HP LaserJet 1515 connected to a Windows 7 PC. The Magenta cartridge is empty; the printer shows a warning to that effect, and won't let me print even black-and-white documents any more. I can't turn the warning off manually using the printer's small console: When I try to enter any menu, the display says "Menu access disabled". I have no idea why. There is a setting to override the warning, but it can't be changed using the Network interface in the browser (Although it is there on the status page) According to the manual,the HP printing tool is supposed to offer a switch for this, but it won't install on my Windows 7. It just rumbles about for half an hour, to magnificently exit with an "unknown error" requiring a reboot. On second look, the problem seems to be that Windows 7 just isn't supported. There is no download link for the tool when you specify Windows 7 as your OS. I just want to print a black-and-white-document on a printer whose black cartridge is still 65% full. Is this indeed impossible? On second thought, I'm cross-posting this on the HP support forum. I'll update here if anything comes up.

  • WINDOWS 7: Make the contents of two folders appear in one

    - by big_smile
    In Windows 7, I have three folders: "Images", "assets" and "all". I want the contents of "Images " and "assets" to appear in "all" automatically without copying those files into that folder (e.g. I don't want to duplicate the files). I also only want the contents to be copied over and not the folders themslves (The reason for this is that if the folders are copied over, they will become sub-directories. I am using a printing hot folder that access "all" but it can't see any subdirectories in "all"). When Images and Assets are updated (e.g. with files being added or deleted), "all" should automatically update as well. How can I do this? This is what I have tried: Libraries: This is a feature built into Windows. It works exactly as I want. However, the print hot folder cannot recognise the library as a folder. Sym Link Extension: I can use this to make the "images" and "assets" folders appear as a sub directories of "all". However, I want the contents of "images"/"assets" to appear in the "all" folder (I don't want the directories to appear as sub directories, because as stated, the print hot folder cannot access sub directories).

  • How to get Path Separator in Perl?

    - by ram
    In case of Java, we can get the path separator using System.getProperty("path.separator"); Is there a similar way in Perl? All I want to do is to find a dir, immediate sub directory. Say I am being given two argumens $a and $b; I am splitting the first one based on the path separator and joining it again except the last fragment and comparing with the second argument. The problem is my code has to be generic and for that I need to know whats the system dependent path separator is? Could you help if there is any way to get it? TIA
