• 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.

• How to get new logs in an EventLogEntyCollection?

  - by Massimo

  I need to monitor security event logs on very busy domain controllers, which generates hundreds of them each minute. I know how to use EventLog, EventLogEntry and EvenLogEntryCollection to open and read a server's event log, but an EvenLogEntryCollection can contain ~300.000 events, and it wraps around continuously (and very fast), so I can't rely on its index to find new entries. So far, the only thing I was able to come up with is saving the timestamp of the last processed log entry and then iterate above the EventLogEntryCollection until I find an EventLogEntry which TimeGenerated properties is greater than the timestamp I saved; but it's terribly slow to iterate on ~300.000 entries to find the new ones. How can I quickly find the new entries in an big event log?

• JavaScript inner function scope chain?

  - by Ding

  In this example var a = 1; ( function(x) { function inner() { alert(a); alert(x); alert(y); } var y = 3; inner(); })(2); When does function inner get created? during execution time or parsing time of outer anonymous function? What is in the scope chain of function inner? What is in the execution context of function inner? I know it is not a simple question, thanks for enlighting me in advance!

• OpenGL game written in C with a Cocoa front-end I want to port to Windows

  - by Philip

  Hello, I'm wondering if someone could offer me some tips on how to go about this. I have a MacOS X OpenGL game that is written in very portable C with the exception of the non-game-play GUI. So in Cocoa I set up the window and OpenGL context, manage preferences, registration, listen for keystrokes etc. But all of the drawing and processing of input is handled in nice portable C. So I want to port to Windows. I figured the obvious way to go about was to use the Win32 api. Then I started to read a primer on Win32 and began to wonder if maybe life isn't too short. Can I do this in C# (without converting the backend to C#)? I'd rather devote the time to learning C# than Win32. Any suggestions would be most welcome. I really don't know a lick about Windows. The last version I regularly used was 3.1...

• php most memory efficient way to return files

  - by bumperbox

  so i have a bunch of files, some can be up to 30-40mb and i want to use php to handle security of the files, so i can control who has access to them that means i have a script sort of like this rough example $has_permission = check_database_for_permission($user, filename); if ($has_permission) { header('Content-Type: image/jpeg'); readfile ($filename); exit; } else { // return 401 error } i would hate for every request to load the full file into memory, as it would soon chew up all the memory on my server with a few simultaneous requests so a couple of questions is readfile the most memory efficient way of doing this? is there some better method of achieving the same outcome, that i am overlooking? server: apache/php5 thanks

• How can I make external script output link to code in Visual Studio?

  - by JoelFan

  I sometimes need to search code for patterns in a way that goes beyond the regex capabilities of Visual Studio (e.g. patterns that depend on what was seen previously in the file or on the contents of other files). So I use Perl to analyze the source and output matching lines, along with the file name and line number. Since this is the exact same format as is produced by the search feature of Visual Studio, I wonder if there is a way to duplicate the functionality where I can double-click on a line and it will display that line in context in Visual Studio. Any ideas?

• 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

• [php + mysql] Save IP in database

  - by Knarf

  When a user logs inn I want to save their IP in the database. How would I do that? What type is best to use for the MySQL field? How would the PHP code to get IP look like? I'm thinking of using it as an extra security feature for the login/session stuff. I'm thinking of checking the IP the user logged in with from the DB with the IP the user have now as addition to checking the session. So that it first check the session, and then check if you have a valid IP. Is that an allright extra feature? And what other things can I do to make it more secure?

• Camel | Need for Scheduling console

  - by user1692063

  I am using camel 2.9.0 in my project. We have a number of routes divided into different camel contexts. Each camel context is bundled separately and deployed in Apache Karaf. Now the problem is divied into 2 parts: 1.) Each route is a scheduled route. Although using Quartz component, we are able to define a cron expressio in each route, we want a console where in we can trigger,stop any route and also put a cron expression to any route.(Scheduling a route through a web console is our main objective). 2.) Also we tried to configure the cron expression for each route through quartz.property. But if someone wants to change the cron expression at runtime in Apache Karaf, then we have to stop the bundle deployed and start in again. What can be done to change the value of cron expression at runtime. Any replies and help would be appreciable. Piyush

• Create link to Sitecore Item

  - by Zooking

  I know I have done this before but I can't seem to remember where or how. I want to create a link to an Item in Sitecore. This code: Sitecore.Data.Items.Item itm = Sitecore.Context.Database.GetItem(someID); return itm.Paths.Path.ToString(); Produces the following string: http://localhost/sitecore/content/Home/Item1/Item11/thisItem I would like to have this string instead: http://localhost/Item1/Item11/thisItem.aspx What is the correct way to get the path to the item? In this case I can't use a normal Sitecore link: Sitecore.Web.UI.WebControls.Link

• Unable to bind in asp.net grid Template Column

  - by OneSmartGuy

  I am having trouble accessing the data field. I receive the error: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control. I can get the value but using <%# getOpenJobs((string)Eval("ParentPart")) % but I need to use it in the if to display a certian picture if it passes the condition. Is there a better way to do this or am i just missing something simple? <telerik:GridTemplateColumn UniqueName="hasOpenJobs" HeaderText=""> <ItemTemplate> <% if (getOpenJobs((string)Eval("ParentPart")) > 1) { %> <img src="../images/job-icon.gif" alt="Open Jobs" /> <%} %> </ItemTemplate> </telerik:GridTemplateColumn>

  Is there something like Python with context manager in Java? For example say I want to do something like the following: getItem(itemID){ Connection c = C.getConnection(); c.open(); try{ Item i = c.query(itemID); }catch(ALLBunchOfErrors){ c.close(); } c.close(); return c; } where in python I just have: with( C.getConnection().open() as c): Item i = c.query(itemID); return i;

• Extending a view to the left side, animated

  - by Heinrich

  Hi, I have a view that I want to extend on the left side using an animation. All borders but the left one should remain the same, so the x position and the width of the view are changing. I use this code: [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:5.0]; self.frame = CGRectMake(self.frame.origin.x-100, self.frame.origin.y, self.frame.size.width+100, self.frame.size.height); [UIView commitAnimations]; If I run this code, the width of the view is set to the new value immediately and then the view is moved to the new x point, but why? How can I change this behaviour? Thanks for your ideas!

• Java training for .NET developers?

  - by C Keene

  We are working with a large retail bank on training 40-50 .Net developers to use Java. They are familiar with C# and .Net framework and have built dozens of "run the business" style apps in .Net. We need advice on how to provide basic Java familiarity, with a focus on back end logic, security and transaction management. Back end is Spring/Hibernate, front end is Ajax (Dojo). Are there any online, self-paced, Java courses that would be good for C#/.Net developers to get up to speed quickly?

• Eclipse: The icons in "Display View" are all greyed out

  - by Mark Silberbauer

  The discussion here describes the "display view" in eclipse which allows one to to quickly evaluate java expressions. The thing is, when I open the display view the icons remain greyed out and I can't execute anything. The only icon that isn't is "clear console". The odd thing is, alot of the screenshots on the web show the same behaviour but the people posting about the feature don't mentioned it. There aren't any options in the context sensitive menu either. I'm trying it on a java project. I've tried it in the debug view and I get the same issue. I'll provide a screenshot once my hosting is sorted. I'm using eclipse 3.4.

On the 3rd sharepoint server the default site crawl just fine...The second web application site (content database) crawls the top site and crawls all sub sites BUT The subsites get the below error in the crawl log. Deleted by the gatherer (The start address or content source that contained this item was deleted and hence this item was deleted.) I have checked the security rights (OK) I have checked the setting to crawl a SharePoint site (if wrong the top site would not work)... ???? Last part = I can crawl 3 other sharepoint sites (web applications/other content databases) on the same server...It seems to be just this one site...

• Getting content of a Facebook page in Adobe Flex

  - by cuneyt

  Hi guys, I wrote a Flex application that sends a UrlRequest to Facebook and gets the content of page as a string. The application user clicks a button, and the application connects to Facebook. And no I do not mean using Facebook API. It is like a screen scraper. This application worked locally, but when deployed to server it gives a sandbox security error. I have my crossdomain.xml on the root, but I think the problem is not that. Not only Facebook, but I cannot get any web site when the application is deployed on server. What should I do to get the content of a remote web page?

• Apache file caching

  - by danp

  How does apache handle caching of certain files, and is it possible to explicitly say that certain files should be aggressively cached more than others, through the standard config files for a given host or virtualhost? To put it in context, I keep a lot of site content in various XML files, and I'd like to be able to say that this file will be used a lot, and therefore cache it as much as possible..? Does apache do this kind of thing intelligently and on the fly..? Will it observe which files are more popular than others and try to match cache hits appropriately..? Lots of questions in one, but the basic idea should be clear enough. edit: to be clear, these are resource files which are loaded and interpreted by PHP - but php as a process is spawned inside apache.. right? Please help!

• Communication between web applications, 1 SSL certificate, other has none

  This the situation: I have one webservice without SSL, which provides two pages for the other web application. When the user submits these pages, an XML file with private information is sent to the webservice. How can I provide the necessary privacy protection on the XML file? Is the one certificate good enough to give the appropriate security? I'm not sure about this one, and am in the preparation phase of a project... So need to know the involved work on this part...
