• processing: convert int to byte

  - by inspectorG4dget

  Hello SO, I'm trying to convert an int into a byte in Processing 1.0.9. This is the snippet of code that I have been working with: byte xByte = byte(mouseX); byte yByte = byte(mouseY); byte setFirst = byte(128); byte resetFirst = byte(127); xByte = xByte | setFirst; yByte = yByte >> 1; port.write(xByte); port.write(yByte); According to the Processing API, this should work, but I keep getting an error at xByte = xByte | setFirst; that says: cannot convert from int to byte I have tried converting 128 and 127 to they respective hex values (0x80 and 0x7F), but that didn't work either. I have tried everything mentioned in the API as well as some other blogs, but I feel like I'm missing something very trivial. I would appreciate any help. Thank you.

• Enterprise distribution Program for iPhone

  - by Mohammed Sadiq

  Hi all, I would like to implement a application which backs up all the internal datas like sms, mms, videos, audios, documents, call history stored in iPhone. But this seems to be not possible with api docs that the apple has released so far ... I have gone through the pdf of ENterprise distribution program and some of the links related to Enterprise Distribution Program, specifies about the Remote wipe and accessing of internal datas like Calendar, sms, mms ect .... But they didnt mention how to do it programmatically. Does Apple provide any special priviledges like extra api support to access the internal data in their Enterprise Distribution Program?. Is there any difference between Enterprise Distribution Program and Standard Distribution Program in the development point of view? And since in-house distribution does not require Apple approval, shall we use some other method which are not officially mentioned in apple docs, to access the internal stored data .. If so can anyone point out the way to do it? Any help would be greatly appreciated awaiting for your response Best regards, Mohammed Sadiq ....

• How to debug a web service written in PHP?

  - by nightcoder

  Hello, I've got a nice question here :) I need to debug my web service written in PHP. Its client is written in C#. After a couple of days of searching I realized this is not an easy task. At least it seems nobody knows the right solution. What is the problem in, actually? We have 2 popular PHP debugging libraries : PHP Debugger from NuSphere and XDebug extension. The problem is they both are controlled from URL query string or with the help of cookies. For example, to enable debugging with PHP Debugger you need to add ?DBGSESSID=xxx parameter to your URL or to have DBGSESSID cookie. But when your web service is called from the external client, the client doesn't have a cookie and doesn't add DBGSESSID url parameter. So how can we debug in this situation? PS. I don't want to write to log files, see request and response headers/data or something like this. I want normal step-by-step debugging and breakpoints. Anyone?

• Getting web page after calling DownloadStringAsync()?

  - by OverTheRainbow

  Hello I don't know enough about VB.Net yet to use the richer HttpWebRequest class, so I figured I'd use the simpler WebClient class to download web pages asynchronously (to avoid freezing the UI). However, how can the asynchronous event handler actually return the web page to the calling routine? Imports System.Net Public Class Form1 Private Shared Sub DownloadStringCallback2(ByVal sender As Object, ByVal e As DownloadStringCompletedEventArgs) If e.Cancelled = False AndAlso e.Error Is Nothing Then Dim textString As String = CStr(e.Result) 'HERE : How to return textString to the calling routine? End If End Sub Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim client As WebClient = New WebClient() AddHandler client.DownloadStringCompleted, AddressOf DownloadStringCallback2 Dim uri As Uri = New Uri("http://www.google.com") client.DownloadStringAsync(uri) 'HERE : how to get web page back from callback function? End Sub End Class Thank you. Edit: I added a global, shared variable and a While/DoEvents/EndWhile, but there's got to be a cleaner way to do this :-/ Public Class Form1 Shared page As String Public Shared Sub AlertStringDownloaded(ByVal sender As Object, ByVal e As DownloadStringCompletedEventArgs) ' If the string request went as planned and wasn't cancelled: If e.Cancelled = False AndAlso e.Error Is Nothing Then page = CStr(e.Result) End If End Sub Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim wc As New WebClient AddHandler wc.DownloadStringCompleted, AddressOf AlertStringDownloaded page = Nothing wc.DownloadStringAsync(New Uri("http://www.google.com")) 'Better way to wait until page has been filled? While page Is Nothing Application.DoEvents() End While RichTextBox1.Text = page End Sub End Class

• Publish content to Facebook C#

  - by Kyle

  I apologize if this has already been answered, but all the information out there on Facebook publishing is so confusing and conflicting, I haven't been able to get anything to work yet. I'm trying to set up an application that runs on my local server to publish content to my organization's fan page (this will tie in with my WCMS to cross-post content). I believe I want a Facebook Connect application to do this which I've set up properly in Facebook and gotten an application key and secret. Here's the code I'm trying to execute, but each time it's run I get "User has not authorized access" even if I'm just trying to publish to the application wall. ConnectSession fbSession = new ConnectSession("APP_KEY", "APP_SECRET"); Api fbAPI = new Api(fbSession); fbAPI.Stream.Publish("hello world"); I've also tried: fbAPI.Stream.Publish("hello world", null, null, FAN_PAGE_ID, APP_ID); I've granted my application access to publish on the fan page.

• Setting custom behaviour via .config file - why doesn't this work?

  - by Andrew Shepherd

  I am attempting to insert a custom behavior into my service client, following the example here. I appear to be following all of the steps, but I am getting a ConfigurationErrorsException. Is there anyone more experienced than me who can spot what I'm doing wrong? Here is the entire app.config file. <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.serviceModel> <behaviors> <endpointBehaviors> <behavior name="ClientLoggingEndpointBehaviour"> <myLoggerExtension /> </behavior> </endpointBehaviors> </behaviors> <extensions> <behaviorExtensions> <add name="myLoggerExtension" type="ChatClient.ClientLoggingEndpointBehaviourExtension, ChatClient, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null"/> </behaviorExtensions> </extensions> <bindings> </bindings> <client> <endpoint behaviorConfiguration="ClientLoggingEndpointBehaviour" name="ChatRoomClientEndpoint" address="http://localhost:8016/ChatRoom" binding="wsDualHttpBinding" contract="ChatRoomLib.IChatRoom" /> </client> </system.serviceModel> </configuration> Here is the exception message: An error occurred creating the configuration section handler for system.serviceModel/behaviors: Extension element 'myLoggerExtension' cannot be added to this element. Verify that the extension is registered in the extension collection at system.serviceModel/extensions/behaviorExtensions. Parameter name: element (C:\Documents and Settings\Andrew Shepherd\My Documents\Visual Studio 2008\Projects\WcfPractice\ChatClient\bin\Debug\ChatClient.vshost.exe.config line 5) I know that I've correctly written the reference to the ClientLoggingEndpointBehaviourExtensionobject, because through the debugger I can see it being instantiated.

• PyQt and unittest - how to handle signals and slots

  - by Einar

  Hello, some small application I'm developing uses a module I have written to check certain web services via a REST API. I've been trying to add unit tests to it so I don't break stuff, and I stumbled upon a problem. I use a lot of signal-slot connections to perform operations asynchronously. For example a typical test would be (pseudo-Python), with postDataDownloaded as a signal: def testConnection(self): "Test connection and posts retrieved" def length_test(): self.assertEqual(len(self.client.post_data), 5) self.client.postDataReady.connect(length_test) self.client.get_post_list(limit=5) Now, unittest will report this test to be "ok" when running, regardless of the result (as another slot is being called), even if asserts fail (I will get an unhandled AssertionError). Example when deliberatiely making the test fail: Test connection and posts retrieved ... ok [... more tests...] OK Traceback (most recent call last): [...] AssertionError: 4 != 5 The slot inside the test is merely an experiment: I get the same results if it's outside (instance method). I also have to add that the various methods I'm calling all make HTTP requests, which means they take a bit of time (I need to mock the request - in the mean time I'm using SimpleHTTPServer to fake the connections and give them proper data). Is there a way around this problem?

• On Android, click to expand list -and- click on a button?

  - by Aurora

  I have just started my career as an android programmer, and am currently relying heavily on the sample code and api examples. I have been working with this api example, to produce an expandable list of items (note this example does not use the ExpadableListView). In playing with the example, I tried to add another widget that would become visible and be gone at the same time as the text (mDialogue in the sample code). This works well with another TextView, but as soon as I tried to add a button widget, it stopped working. The list would expand on first click, showing my hidden TextView and Button, but it will not disappear on further clicks. The button is however, clickable, and I was able to set up an onClick listener to change the button text back and forth. I'm starting to wonder, is it just not possible to have a clickable item inside a clickable list item? Or is there some kind of work around? Would it solve my problem if I used ExpandableListView?

  I am trying to start working with excel documents through the OpenXML SDK Spreadsheet API. But I havent found any good guides or even examples on how to create a xlsx file from scratch.

It might be easier but I not comfortable using a technique I dont feel that I understand "pretty" good atleast. So my question is: Anyone has any god tips on articles or books or any other type of resource that explains the API. Thanks in advance. /johan

• Referencing assemblies created with ILMerge in Visual Studio projects

  - by Daniel Schaffer

  I have a solution in Visual Studio with 5 projects. They are: Foo.Core: Core functionality Foo.Api: Generated code built on top of core Foo.Web: Web-specific extensions Foo.Web.Mvc: MVC-specific extensions Newtonsoft.Json: 3rd party library I want to use ILMerge to merge Foo.Core, Foo.Api and Newtonsoft.Json into a single assembly, called Foo. That's the easy part. The problem I'm running into is that Foo.Web and Foo.Web.Mvc both need to reference all three of the merged assemblies. If I reference the original assemblies, they will have invalid references after I do the ILMerge. If I reference the ILMerged assembly, I have to reference a debug assembly and then change it before I package everything up, which doesn't seem ideal. I've tried creating a project called Foo, which references the 3 merged assemblies and replaces its own output with the ILmerged assembly, but that doesn't seem to work at all. Is there a reliable way to do this?

• WPF Background Thread Invocation

  - by jeffn825

  Maybe I'm mis-remembering how Winforms works or I'm overcomplicating the hell out of this, but here's my problem. I have a WPF client app application that talks to a server over WCF. The current user may "log out" of the WPF client, which closes all open screens, leaves only the navigation pane, and minimizes the program window. When the user re-maximizes the program window, they are prompted to log in. Simple. But sometimes things happen on background threads - like every 5 minutes the client tries to make a WCF calls that refreshes some cached data. And what if the user is logged out when this 5 minute timer triggers? Well, then the user should be prompted to log back in...and this must of course happen on the UI thread. private static ISecurityContext securityContext; public static ISecurityContext SecurityContext { get { if (securityContext == null) { // Login method shows a window and prompts the user to log in Application.Current.Dispatcher.Invoke((Action)Login); } return securityContext; } } So far so good, right? But what happens when multiple threads hit this spot of code? Well, my first intuition was that since I'm syncrhonizing across the Application.Current.Dispatcher, I should be fine, and whichever thread hit first would be responsible for showing the login form and getting the user logged in... Not the case... Thread 1 will hit the code and call ShowDialog on the login form Thread 2 will also hit the code and will call Login as soon as Thread 1 has called ShowDialog, since calling ShowDialog unblocked Thread 1 (I believe because of the way the WPF message pump works) All I want is a synchronized way of getting the user logged back into the application...what am I missing here? Thanks in advance.

• WCF Http Bindings, Require SSL

  - by JoshKraker

  I have the following binding I'm using with my wsHttpBinding webservice. <binding name="wsHttpConfig"> <security> <transport clientCredentialType="None"/> </security> </binding> The issue is that it allows for the client to connect using either Http or Https. I would like to require them to use SSL. I tried adding the following: <system.web.extensions> <scripting> <webServices> <authenticationService enabled="true" requireSSL = "true"/> </webServices> </scripting> </system.web.extensions> But it had no effect; client could still connect with Http. I then tried checking the "Require SSL" in the IIS7 SSL Settings and had client certificates radio set to Accept. Now, when I try to view the service I am getting the error "Could not find a base address that matches scheme http for the endpoint with binding WSHttpBinding. Registered base address schemes are [https]." Anyone know exactly how to fix this error? I have been googling for the last 3 hours trying 500 different combinations (not 500, but too many to list) and could not get anything to run.

• How do I specify a crossdomain policy file to allow Flash to grab a bitmap from an RTMP (Wowza) vide

  - by Ken Smith

  I'm trying to get a bitmap/snapshot of a Wowza video stream playing on my client, like so: var bitmapData:BitmapData = new BitmapData(view.videoPlayerComponent.width, view.videoPlayerComponent.height); bitmapData.draw(view.videoPlayerComponent); When I do this, I get this error message: SecurityError: Error #2123: Security sandbox violation: BitmapData.draw: http://localhost:51150/Resources/WRemoteWebCam.swf cannot access rtmp://localhost/videochat/smithkl42._default/. No policy files granted access. I presume the error comes from not being able to locate the appropriate crossdomain.xml file. I'm not quite sure where it's looking for it, and a wireshark sniff was inconclusive, so I've tried placing one in each of the following places: http://localhost/crossdomain.xml http://localhost:1935/crossdomain.xml http://localhost:51150/crossdomain.xml I can retrieve the file successfully from each of those three locations. (I'm pretty sure that the last one wouldn't have any effect, since it's just the location of the web site which hosts the page that hosts the .swf file, but on the off chance...) These are the contents of the file that it's grabbing in each instance: <cross-domain-policy> <allow-access-from domain="*" to-ports="*" /> </cross-domain-policy> And it's still throwing that same error message. I've also followed the instructions on the Wowza forums, to turn on StreamVideoSampleAccess in the [install]\conf[appname]\Application.xml, with no joy: <Client> <IdleFrequency>-1</IdleFrequency> <Access> <StreamReadAccess>*</StreamReadAccess> <StreamWriteAccess>*</StreamWriteAccess> <StreamAudioSampleAccess>*</StreamAudioSampleAccess> <StreamVideoSampleAccess>*</StreamVideoSampleAccess> <SharedObjectReadAccess>*</SharedObjectReadAccess> <SharedObjectWriteAccess>*</SharedObjectWriteAccess> </Access> </Client> Any thoughts?

• DataContract Known Types - passing array

  - by Erup

  Im having problems when passing an generic List, trough a WCF operation. In this case, there is a List of int. The example 4 is described here in MSDN. Note that in MSDN sample, is described: // This will serialize and deserialize successfully because the generic List is equivalent to int[], which was added to known types. Above, is the DataContract: [DataContract] [KnownType(typeof(int[]))] [KnownType(typeof(object[]))] public class AccountData { [DataMember] public object accNumber1; [DataMember] public object accNumber2; [DataMember] public object accNumber3; [DataMember] public object accNumber4; } In client side, Im calling the operation like this: DataTransfer.Service.AccountData data = new DataTransfer.Service.AccountData() { accNumber1 = 100, accNumber2 = new int[100], accNumber3 = new List<int>(), accNumber4 = new ArrayList() }; cService.AddAccounts(data); Also, here is the decorations of the generated AccountData obj (WCF proxy): [System.Diagnostics.DebuggerStepThroughAttribute()] [System.CodeDom.Compiler.GeneratedCodeAttribute("System.Runtime.Serialization", "3.0.0.0")] [System.Runtime.Serialization.DataContractAttribute(Name="AccountData", Namespace="http://schemas.datacontract.org/2004/07/DataTransfer.Service")] [System.SerializableAttribute()] [System.Runtime.Serialization.KnownTypeAttribute(typeof(DataTransfer.Client.CustomerServiceReference.PurchaseOrder))] [System.Runtime.Serialization.KnownTypeAttribute(typeof(DataTransfer.Client.CustomerServiceReference.Customer))] [System.Runtime.Serialization.KnownTypeAttribute(typeof(int[]))] [System.Runtime.Serialization.KnownTypeAttribute(typeof(object[]))]

• Google maps : How to open an InfoWindow for a Polygon by clicking on it?

  - by JB

  Hello ! I have a simple question, but i can't find the answer in the Google Maps API documentation... I have a map with 13 polygons drawed by the API. Here is an exemple of one of these polygons : var zone_up_montblanc = new GPolygon([ new GLatLng(46.21270329318585, 6.134903900311617), new GLatLng(46.20538443787925, 6.136844716370282), new GLatLng(46.20525043957647, 6.141375978638086), new GLatLng(46.20698751554006, 6.148050266912262), new GLatLng(46.21110286985207, 6.153203229026629), new GLatLng(46.21730757985668, 6.151718301267355), new GLatLng(46.22092122197341, 6.153676364285801), new GLatLng(46.22615123408969, 6.149844858907489), new GLatLng(46.22851200024137, 6.149876939987202), new GLatLng(46.22945159836955, 6.142758190170017), new GLatLng(46.21735908463437, 6.141457132705133), new GLatLng(46.21753573755057, 6.138058122426195), new GLatLng(46.21270329318585, 6.134903900311617) ], "#6b1f43", 2, 0.9, "#92c87f", 0.5); then : map.addOverlay(zone_up_montblanc); Polygons appears on my map, no problem. But the thing I have to do now is to open an "InfoWindow" by clicking on each polygons (with a different content for each polygons). Did someone have an idea or an example? Thanks a lot for your help !

• NoSuchMethod exception thrown in GWT

  - by eb1

  I'm starting to get my feet wet in the latest Google Web Toolkit using the Eclipse plugin on OS X 10.5.8. So far I've been able to get the client up and running, which is great. The server, though, is a different matter. I'm trying to link to a .jar file that has some classes I want to use in a server ServiceImpl class, but it seems to have glommed onto a previous iteration of the .jar - I've added a method, rebuilt the jar, removed the jar from the libraries tab on the GWT project's build path (as well as on the exports) and reincluded the jar. No luck - I'm still getting: [WARN] Exception while dispatching incoming RPC call com.google.gwt.user.server.rpc.UnexpectedException: Service method 'public abstract org.gwtapplication.client.LWDocument org.gwtapplication.client.DocumentService.getDocument()' threw an unexpected exception: java.lang.NoSuchMethodError: org.externalmodel.MyReallyValidClass.toSomething()Ljava/lang/String; at com.google.gwt.user.server.rpc.RPC.encodeResponseForFailure(RPC.java:378) at com.google.gwt.user.server.rpc.RPC.invokeAndEncodeResponse(RPC.java:581) ...

Any clue where I should be looking?

• python win32com EXCEL data input error

  Welcome, I'm exporting results of my script into Excel spreadsheet.

I put several different types of data strings, ints, floats, lists and it works fine. When I run the sript for the second time it works fine - no error. What's going on? PS. This is code that generates error, what's strange is that the error doesn't occur always.

• AsyncTask, RejectedExecutionException and Task Limit

  - by Samuh

  I am fetching lots of thumbnails from a remote server and displaying them in a grid view, using AsyncTask. The problem is, my grid view displays 20 thumbnails at a time, so that creates 20 AsyncTasks and starts 20 executes, one per thumbnail. I get RejectedExecution exception in my code. I recall reading somewhere that there is a limit to number of tasks that AsyncTask can have in its queue at a time, i might be hitting that. Was this bar lifted? Is there a way to increase this limit? Is it safe to just ignore this exception?(by having an empty catch(RejectedException e){} block?) I am running this code on Android 1.6 emulator and the API level in my code(minSDKVersion is 3). [EDIT: Added SDK and API level info]

• DomainContext class is not created in a RIA services class library solution

  - by Konamiman

  I have created a RIA services class library project and things are not going as I expected. The problem is that when I add domain service classes to the server project, the corresponding domain context classes are not generated on the client project. I start by creating a new project of type WCF RIA services class library. The generated solution has two projects: RIAServicesLibrary1 (the Silverlight class library project) and RIAServicesLibrary1.Web (the class library that will hold the services). Then I add a new project item to RIAServicesLibrary1.Web of type DomainServiceClass. I add a sample method so that the resulting class code is: namespace RIAServicesLibrary1.Web { using System; using System.Collections.Generic; using System.ComponentModel; using System.ComponentModel.DataAnnotations; using System.Linq; using System.ServiceModel.DomainServices.Hosting; using System.ServiceModel.DomainServices.Server; // TODO: Create methods containing your application logic. [EnableClientAccess()] public class DomainService1 : DomainService { [Invoke] void DoSomething() { } } } Then I generate the whole solution and... nothing happens on the client project. The Generated_Code folder is empty, and the domain context object for the service is not here. Funny enough, if I add a new item of type Authentication domain service, it works as expected: the file RIAServicesLibrary1.Web.g.cs is created on the client project, containing the AuthenticationDomainService1 class as expected. So what's happening here? Am I doing something wrong? Note: I am using Visual Studio 2010 Ultimate RTM and WCF RIA services 1.0.

• Nice name for `decorator' class?

  - by Lajos Nagy

  I would like to separate the API I'm working on into two sections: 'bare-bones' and 'cushy'. The idea is that all method calls in the 'cushy' section could be expressed in terms of the ones in the 'bare-bones' section, that is, they would only serve as convenience methods for the quick-and-dirty. The reason I would like to do this is that very often when people are beginning to use an API for the first time, they are not interested in details and performance: they just want to get it working. Anybody tried anything similar before? I'm particularly interested in naming conventions and organizing the code.

• How can I get a Silverlight application to check for an update without the user clicking a button?

  - by Edward Tanguay

  I have made an out-of-browser silverlight application which I want to automatically update every time there is a new .xap file uploaded to the server. When the user right-clicks the application and clicks on Updates, the default is set to "Check for updates, but let me choose whether to download and install them": This leads me to believe that it is possible to make my Silverlight application automatically detect if there is a new .xap file present on the server, and if there is, the Silverlight client will automatically ask the user if he would like to install it. This however is not the case. I upload a new .xap file and the Silverlight application does nothing. Even if I add this to my App.xaml.cs: -- private void Application_Startup(object sender, StartupEventArgs e) { this.RootVisual = new BaseApp(); if (Application.Current.IsRunningOutOfBrowser) { Application.Current.CheckAndDownloadUpdateAsync(); } } and update the .xap file, the Silverlight application does nothing. This information leads me to believe that I have to make a button which the user clicks to see if there is an update. But I don't want the user to have to click a button every day to see if there is an update. I want the application to check by itself if there is a new .xap file and if there is, let the client ask the user if he wants the update. How do I make my Silverlight application check, each time it starts, if there is a new .xap file, and if there is, pass control to the Silverlight client to ask the user if he wants to download it, as the above dialogue implies is possible?

• Use VersionControlExt.Explorer outside Visual Studio

  - by Ian

  Hi All, I'm developing a TFS tool to assist the developers in our company. This said tool needs to be able to "browse" the TFS server like in the Source Control Explorer. I believe that by using VersionControlExt.Explorer.SelectedItems, a UI will pop-up that will enable the user to browse the TFS server (please correct me if I'm wrong). However, VersionControlExt is only accessible when developing inside Visual Studio (aka Plugin). Unfortunately, I am developing a Windows Application that won;t run inside VS. So the question is, Can I use VersionControlExt outside of Visual Studio? If yes, how? Here's an attempt on using the Changset Details Dialog outside of Visual Studio string path = System.IO.Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location); Assembly vcControls = Assembly.LoadFile(path + @"\Microsoft.TeamFoundation.VersionControl.Controls.dll"); Assembly vcClient = Assembly.LoadFile(path + @"\Microsoft.TeamFoundation.VersionControl.Client.dll"); Type dialogChangesetDetailsType = vcControls.GetType("Microsoft.TeamFoundation.VersionControl.Controls.DialogChangesetDetails",true); Type[] ctorTypes = new Type[3] {vcClient.GetType("Microsoft.TeamFoundation.VersionControl.Client.VersionControlSever"), vcClient.GetType("Microsoft.TeamFoundation.VersionControl.Client.Changeset"), typeof(System.Boolean)}; ConstructorInfo ctorInfo = dialogChangesetDetailsType.GetConstructor(ctorTypes); Object[] ctorObjects = new Object[3] {VersionControlHelper.CurrentVersionControlServer, uc.ChangeSet, true}; Object oDialog = ctorInfo.Invoke(ctorObjects); dialogChangesetDetailsType.InvokeMember("ShowDialog", BindingFlags.InvokeMethod, null, oDialog, null);

• Storable Geocoding/reverse Geocoding services

  - by Marcus

  Im currently looking into an easy way to query and store Latitude/Longitude for a given address. There are a plentitude of services out there, but none actually allows me to store the data I retieve (i.e. Google Maps API TOS, Yahoo! Maps API TOS). As I wan't to use them for a distance search I can't really query the data on the fly. Are there any services that acutally allow to store the location you get for an adress? And I want to do it more or less worldwide. (As a side question, I might need the other way around soon, getting from latitude/longitude to an address or place name, but this falls under the same terms as the above).
