  • Eclipse Blackberry Preprocessor Not Working?

    - by Jessica
    I've already followed the directions @ http://stackoverflow.com/questions/1383277/using-preprocessor-directives-in-blackberry-jde-plugin-for-eclipse for making sure the blackberry plugin preprocessing hook is (theoretically) enabled. I'm using Eclipse 3.5.1 with Blackberry Plugin 1.1 with BB SDKs 4.7.0 and 4.6.0. I have my preprocessor defines set (and I've tried in both the Project's Blackberry Properties as well as the Workspace Blackberry Build settings), and checked their capitalization and spelling carefully too. I'm fairly confident the actual code to say "this stuff should be preprocessed" is good, because including/excluding preprocessed code seems to work fine on command line builds: //#preprocess --- at beginning of file and then code blocks like this throughout: //#ifndef jde_4_7 /* //#endif //#ifdef jde_4_7 import net.rim.device.api.ui.TouchEvent; //#endif //#ifndef jde_4_7 */ //#endif So what I can't figure out what else could be wrong that would cause Eclipse to not compile in my preprocessed code unless I remove the comments that are supposed to prevent the touch code from building into a build for blackberries that don't support touch. At one point it used to work (and no I haven't updated Eclipse), but sometime in the last couple of weeks it seemed to just stop working. And I'm getting kind of tired of the error-prone process of searching for ifdefs and manually commenting/uncommenting touch code and looking for a better solution while I do testing and initial development requiring testing both touch and non-touch functionality. Any other ideas on what could be wrong or how to fix it?

  • Empty responseText from XMLHttpRequest

    - by PurplePilot
    I have written an XMLHttpRequest which runs fine but returns an empty responseText. The javascript is as follows: var anUrl = "http://api.xxx.com/rates/csv/rates.txt"; var myRequest = new XMLHttpRequest(); callAjax(anUrl); function callAjax(url) { myRequest.open("GET", url, true); myRequest.onreadystatechange = responseAjax; myRequest.setRequestHeader("Cache-Control", "no-cache"); myRequest.send(null); } function responseAjax() { if(myRequest.readyState == 4) { if(myRequest.status == 200) { result = myRequest.responseText; alert(result); alert("we made it"); } else { alert( " An error has occurred: " + myRequest.statusText); } } } The code runs fine. I can walk through and I get the readyState == 4 and a status == 200 but the responseText is always blank. I am getting a log error (in Safari debug) of Error dispatching: getProperties which I cannot seem to find reference to. I have run the code in Safari and Firefox both locally and on a remote server. The URL when put into a browser will return the string and give a status code of 200. I wrote similar code to the same URL in a Mac Widget which runs fine, but the same code in a browser never returns a result.

    Hello All, There are a lot of questions on Stackoverflow about curl but I could not figure out what is that I am doing what I am not supposed to. I am trying to call a RESTful service that I had written using Jersey API and am trying to POST an xml string to it and I get HTTP 415 error which is supposed to be a Media Type error. Here in my shell script call to 1st service: abc=curl http://gf...:8080/InChItoD/inchi/3dstructure?InChIstring=$inchi echo $abc (this works fine the output that it returns is given below.)

  • Oracle & Active Directory : A love/hate relationship

    - by Frank
    Hi SO'ers, I'm currently trying to access Active Directory via the dbms_ldap API in Pl/Sql (Oracle). The trouble is that I'm not able to connect with my own username and password or anynoymously. However, in C# I can connect anonymously with this code : DirectoryEntry ldap = new DirectoryEntry("LDAP://Hostname"); DirectorySearcher searcher = new DirectorySearcher(ldap); searcher.Filter = "(SAMAccountName=username)"; SearchResult result = searcher.FindOne(); If I try to connect anonymously in Oracle, I only get the error(ORA-31202 : LDAP client/server error) when I try to search (and the result code for the bind is SUCCESS)... my_session := dbms_ldap.init('HOST','389'); retval := dbms_ldap.simple_bind_s(my_session, '', ''); retval := dbms_ldap.search_s(my_session, ldap_base, dbms_ldap.scope_subtree, 'objectclass=*', my_attrs, 0, my_message); Why is the anonymous connection is C# works but doesn't work in Pl/Sql? Do you have any other idea to connect to Active Directory via Oracle? Help me reunite them together. Thanks. Edit When I bind with anonymous credentials I get : ORA-31202: DBMS_LDAP: LDAP client/server error 00000000: LdapErr: DSID-0C090627, comment: In order to perform this operation a successful bind must be completed on the connection And if I try to connect with my credentials, which are supposed to be valid since I'm connected to the domain with it... I get : ORA-31202: DBMS_LDAP: LDAP client/server error Invalid credentials 80090308: LdapErr: DSID-0C090334, comment: AcceptSecurityContext error

  • FusionCharts vs GoogleCharts vs HighCharts suggestions required for commercial use

    - by Forte
    I find that FusionCharts v3 evaluation and HighCharts cannot be used for commercial purpose. Google charts is the best option but those are not as good looking as any of the above. They don't even have 3d charts although their visualization API does support 3D which i cannot find. Is there any open source graphing or charting solution available which can be used in commercial products? I even looked in to Open Flash Charts 2 but found that the developer had left the project long time a go and the currently out libs are way too buggy. I had to fix more than 50 bugs to get their 1 chart working. I tried to fix others but couldn't get Pie charts etc. working. What i'm looking for is - 1. Attractive 3d column chart. 2. 3d Pie Chart. 3. Spline Chart. 4. Geographical Chart. Does anyone knows any open source or free solution which can be used for commercial products? Cheers!

  • Use RegEx in Java to extract parameters in between parentheses

    - by lars_bx
    I'm writing a utility to extract the names of header files from JSPs. I have no problem reading the JSPs line by line and finding the lines I need. I am having a problem extracting the specific text needed using regex. After looking at many similar questions I'm hitting a brick wall. An example of the String I'll be matching from within is: <jsp:include page="<%=Pages.getString(\"MY_HEADER\")%>" flush="true"></jsp:include> All I need is MY_HEADER for this example. Any time I have this tag: <%=Pages.getString I need what comes between this: <%=Pages.getString(\" and this: )%> Here is what I have currently (which is not working, I might add) : String currentLine; while ((currentLine = fileReader.readLine()) != null) { Pattern pattern = Pattern.compile("<%=Pages\\.getString\\(\\\\\"([^\\\\]*)"); Matcher matcher = pattern.matcher(currentLine); while(matcher.find()) { System.out.println(matcher.group(1).toString()); }} I need to be able to use the Java RegEx API and regex to extract those header names. Any help on this issue is greatly appreciated. Thanks! EDIT: Resolved this issue, thankfully. The tricky part was, after being given the right regex, it had to be taken into account that the String I was feeding to the regex was always going to have two " / " characters ( (/"MY_HEADER"/) ) that needed to be escaped in the pattern. Here is what worked (thanks to the help ;-)): Pattern pattern = Pattern.compile("<%=Pages\\.getString\\(\\\\\"([^\\\\\"]*)");

  • Using ScriptGetProperties with Delphi

  • Context migration in CUDA.NET

    - by Vyacheslav
    I'm currently using CUDA.NET library by GASS. I need to initialize cuda arrays (actually cublas vectors, but it doesn't matters) in one CPU thread and use them in other CPU thread. But CUDA context which holding all initialized arrays and loaded functions, can be attached to only one CPU thread. There is mechanism called context migration API to detach context from one thread and attach it to another. But i don't how to properly use it in CUDA.NET. I tried something like this: class Program { private static float[] vector1, vector2; private static CUDA cuda; private static CUBLAS cublas; private static CUdeviceptr ptr; static void Main(string[] args) { cuda = new CUDA(false); cublas = new CUBLAS(cuda); cuda.Init(); cuda.CreateContext(0); AllocateVectors(); cuda.DetachContext(); CUcontext context = cuda.PopCurrentContext(); GetVectorFromDeviceAsync(context); } private static void AllocateVectors() { vector1 = new float[]{1f, 2f, 3f, 4f, 5f}; ptr = cublas.Allocate(vector1.Length, sizeof (float)); cublas.SetVector(vector1, ptr); vector2 = new float[5]; } private static void GetVectorFromDevice(object objContext) { CUcontext localContext = (CUcontext) objContext; cuda.PushCurrentContext(localContext); cuda.AttachContext(localContext); //change vector somehow vector1[0] = -1; //copy changed vector to device cublas.SetVector(vector1, ptr); cublas.GetVector(ptr, vector2); CUDADriver.cuCtxPopCurrent(ref localContext); } private static void GetVectorFromDeviceAsync(CUcontext cUcontext) { Thread thread = new Thread(GetVectorFromDevice); thread.IsBackground = false; thread.Start(cUcontext); } } But execution fails on attempt to copy changed vector to device because context is not attached? Any ideas how i can get it work?

  • Interpolation and Morphing of an image in labview and/or openCV

    - by Marc
    I am working on an image manipulation problem. I have an overhead projector that projects onto a screen, and I have a camera that takes pictures of that. I can establish a 1:1 correspondence between a subset of projector coordinates and a subset of camera pixels by projecting dots on the screen and finding the centers of mass of the resulting regions on the camera. I thus have a map proj_x, proj_y <-- cam_x, cam_y for scattered point pairs My original plan was to regularize this map using the Mathscript function griddata. This would work fine in MATLAB, as follows [pgridx, pgridy] = meshgrid(allprojxpts, allprojypts) fitcx = griddata (proj_x, proj_y, cam_x, pgridx, pgridy); fitcy = griddata (proj_x, proj_y, cam_y, pgridx, pgridy); and the reverse for the camera to projector mapping Unfortunately, this code causes Labview to run out of memory on the meshgrid step (the camera is 5 megapixels, which apparently is too much for labview to handle) I then started looking through openCV, and found the cvRemap function. Unfortunately, this function takes as its starting point a regularized pixel-pixel map like the one I was trying to generate above. However, it made me hope that functions for creating such a map might be available in openCV. I couldn't find it in the openCV 1.0 API (I am stuck with 1.0 for legacy reasons), but I was hoping it's there or that someone has an easy trick. So my question is one of the following 1) How can I interpolate from scattered points to a grid in openCV; (i.e., given z = f(x,y) for scattered values of x and y, how to fill an image with f(im_x, im_y) ? 2) How can I perform an image transform that maps image 1 to image 2, given that I know a scattered mapping of points in coordinate system 1 to coordinate system 2. This could be implemented either in Labview or OpenCV. Note: I am tagging this post delaunay, because that's one method of doing a scattered interpolation, but the better tag would be "scattered interpolation"

  • Deserializing a complex JSON result (array of dictionaries) with TouchJSON

    - by jpm
    I did a few tests with TouchJSON last night and it worked pretty well in general for simple cases. I'm using the following code to read some JSON content from a file, and deserialize it: NSString *jsonString = [[NSString alloc] initWithContentsOfFile:@"data.json"]; NSData *jsonData = [jsonString dataUsingEncoding:NSUTF32BigEndianStringEncoding]; NSError *error = nil; NSDictionary *items = [[CJSONDeserializer deserializer] deserializeAsDictionary:jsonData error:&error]; NSLog(@"total items: %d", [items count]); NSLog(@"error: %@", [error localizedDescription]); That works fine if I have a very simple JSON object in the file (i.e. a dictionary): {"id": "54354", "name": "boohoo"} This way I was able to get access to the array of values, as I wanted to get the item based on its index within the list: NSArray *items_list = [items allValues]; NSString *name = [items_list objectAtIndex:1]; (I understand that I could have fetched the name with the dictionary API) Now I would like to deserialize a semi-complex JSON string, which represents an array of dictionaries. An example of such a JSON string is below: [{"id": "123456", "name": "touchjson"}, {"id": "3456", "name": "bleh"}] When I try to run the same code above against this new content in the data.json file, I don't get any results back. My NSLog() call says "total items: 0", and no error is coming back in the NSError object. Any clues on what is going on? I'm completely lost on what to do, as there isn't much documentation available for TouchJSON, and much less usage examples.

  • Preserving case in HTTP headers with Ruby's Net:HTTP

    - by emh
    Although the HTTP spec says that headers are case insensitive; Paypal, with their new adaptive payments API require their headers to be case-sensitive. Using the paypal adaptive payments extension for ActiveMerchant (http://github.com/lamp/paypal_adaptive_gateway) it seems that although the headers are set in all caps, they are sent in mixed case. Here is the code that sends the HTTP request: headers = { "X-PAYPAL-REQUEST-DATA-FORMAT" => "XML", "X-PAYPAL-RESPONSE-DATA-FORMAT" => "JSON", "X-PAYPAL-SECURITY-USERID" => @config[:login], "X-PAYPAL-SECURITY-PASSWORD" => @config[:password], "X-PAYPAL-SECURITY-SIGNATURE" => @config[:signature], "X-PAYPAL-APPLICATION-ID" => @config[:appid] } build_url action request = Net::HTTP::Post.new(@url.path) request.body = @xml headers.each_pair { |k,v| request[k] = v } request.content_type = 'text/xml' proxy = Net::HTTP::Proxy("127.0.0.1", "60723") server = proxy.new(@url.host, 443) server.use_ssl = true server.start { |http| http.request(request) }.body (i added the proxy line so i could see what was going on with Charles - http://www.charlesproxy.com/) When I look at the request headers in charles, this is what i see: X-Paypal-Application-Id ... X-Paypal-Security-Password... X-Paypal-Security-Signature ... X-Paypal-Security-Userid ... X-Paypal-Request-Data-Format XML X-Paypal-Response-Data-Format JSON Accept */* Content-Type text/xml Content-Length 522 Host svcs.sandbox.paypal.com I verified that it is not Charles doing the case conversion by running a similar request using curl. In that test the case was preserved.

  • Using Windows and MMSystem in Delphi

    - by Jose Martinez
    Hi I am making a program to open and close the cd reader in which I have thought to write data to CD, the problem is the basis of the problem, which use "uses Windows 'and' uses MMSystem" but the problem is that when I use both at the same time being "uses Windows, MMSystem" gives an error and the program does not compile, I am using Delphi 2010, the strange thing is that when I use only one either Windows or MMSystem works fine and compiles. The error when I try to compile is: 'Could not find program' The code in question is this: mciSendString ('Set cdaudio door open wait', nil, 0, handle); I have two things to ask you first is how I avoid the error when using the two (Windows and MMSystem) and the other question was if he could open the CD player without using MMSystem, bone using Windows API, but not where to start The source : program Project1; {$APPTYPE CONSOLE} uses SysUtils,Windows,MMSystem; procedure opencd; begin mciSendString('Set cdaudio door open wait', nil, 0, 0); end; begin try Writeln('test'); except on E: Exception do Writeln(E.ClassName, ': ', E.Message); end; end.

  • Eigenvector computation using OpenCV

    - by Andriyev
    Hi I have this matrix A, representing similarities of pixel intensities of an image. For example: Consider a 10 x 10 image. Matrix A in this case would be of dimension 100 x 100, and element A(i,j) would have a value in the range 0 to 1, representing the similarity of pixel i to j in terms of intensity. I am using OpenCV for image processing and the development environment is C on Linux. Objective is to compute the Eigenvectors of matrix A and I have used the following approach: static CvMat mat, *eigenVec, *eigenVal; static double A[100][100]={}, Ain1D[10000]={}; int cnt=0; //Converting matrix A into a one dimensional array //Reason: That is how cvMat requires it for(i = 0;i < affnDim;i++){ for(j = 0;j < affnDim;j++){ Ain1D[cnt++] = A[i][j]; } } mat = cvMat(100, 100, CV_32FC1, Ain1D); cvEigenVV(&mat, eigenVec, eigenVal, 1e-300); for(i=0;i < 100;i++){ val1 = cvmGet(eigenVal,i,0); //Fetching Eigen Value for(j=0;j < 100;j++){ matX[i][j] = cvmGet(eigenVec,i,j); //Fetching each component of Eigenvector i } } Problem: After execution I get nearly all components of all the Eigenvectors to be zero. I tried different images and also tried populating A with random values between 0 and 1, but the same result. Few of the top eigenvalues returned look like the following: 9805401476911479666115491135488.000000 -9805401476911479666115491135488.000000 -89222871725331592641813413888.000000 89222862280598626902522986496.000000 5255391142666987110400.000000 I am now thinking on the lines of using cvSVD() which performs singular value decomposition of real floating-point matrix and might yield me the eigenvectors. But before that I thought of asking it here. Is there anything absurd in my current approach? Am I using the right API i.e. cvEigenVV() for the right input matrix (my matrix A is a floating point matrix)? cheers

  • EWS 2010: Public Folder Problem using .NET

    - by Daniel
    I've recently coded a .NET Console app using C#. It's purpose was to read the emails within a specific folder, parse them for specific values and save them to a database. Our email system, at the time I originally coded this, was Exchange 2003. However, I was made aware we would soon be upgrading to Exchange 2010: ergo, I built the code to work in both environments. Following the migration to 2010, however, the app has broken. The app uses the EWS API for 2010 functionality. When it attempts to use the ExchangeService's FindFolders method to find the publicfoldersroot, it throws an exception. Here's the code: ExchangeService service = new ExchangeService(); FindFoldersResults findRootFldrs; service.UseDefaultCredentials = true; service.AutodiscoverUrl("[email protected]", delegate(string x) { return true; }); FolderView fview = new FolderView(100); fview.Traversal = FolderTraversal.Deep; if (findRootFldrsSub == null) { //Set to root to test local folders -- findRootFldrs = service.FindFolders(WellKnownFolderName.PublicFoldersRoot, fview); } The exception: "The mailbox that was requested doesn't support the specified RequestServerVersion" I've attempted: -Setting the exchangeservice to 2007 (throws an exception: "An internal server error occurred. The operation failed.") -Giving myself the highest level of permission to the Public Folder (no effect) -Manually setting my credentials (no effect) I can view the public folders in outlook; the publicfoldersroot property is available in the intellisense; the code works on local folders (I can parse my inbox). My current thinking is that it's a setting on the recent setup of Exchange 2010: unfortunately that isn't really my field.

  • Using @Context, @Provider and ContextResolver in JAX-RS

    - by Tamás
    I'm just getting acquainted with implementing REST web services in Java using JAX-RS and I ran into the following problem. One of my resource classes requires access to a storage backend, which is abstracted away behind a StorageEngine interface. I would like to inject the current StorageEngine instance into the resource class serving the REST requests and I thought a nice way of doing this would be by using the @Context annotation and an appropriate ContextResolver class. This is what I have so far: In MyResource.java: class MyResource { @Context StorageEngine storage; [...] } In StorageEngineProvider.java: @Provider class StorageEngineProvider implements ContextResolver<StorageEngine> { private StorageEngine storage = new InMemoryStorageEngine(); public StorageEngine getContext(Class<?> type) { if (type.equals(StorageEngine.class)) return storage; return null; } } I'm using com.sun.jersey.api.core.PackagesResourceConfig to discover the providers and the resource classes automatically, and according to the logs, it picks up the StorageEngineProvider class nicely (timestamps and unnecessary stuff left out intentionally): INFO: Root resource classes found: class MyResource INFO: Provider classes found: class StorageEngineProvider However, the value of storage in my resource class is always null - neither the constructor of StorageEngineProvider nor its getContext method is called by Jersey, ever. What am I doing wrong here?

  • XMPP and Android interaction

    - by Ameya Phadke
    I am currently finding about how to build a XMPP client application on android 2.0.I came across this link which somewhat talks about the same problem.I am a newbie to android dev and thus found the solution given there to be difficult to digest. The system currently has Active MQ as a JMS provider.My job is to fed the messages coming from JMS to the XMPP server and then develope XMPP client on android 2.0 which will listen and show notification to the events pushed by the server. I have following concerns(which might sound foolish) 1.How do I push the events from JMS to the XMPP server which will in turn push them on android? 2.Which XMPP server implementation I should use?I have 3 options * Openfire: Very mature (was a commercial product), but sounds like it's heavyweight, written in Java * Prosody: Lightweight and easy to use, written in Lua. Doesn't have PubSub module yet * Tigase: Also lightweight, written in Java, supports PubSub How do I test and setup these servers.Do I need PubSub funcationality for my app? 3.For XMPP client I came across Smack API given here which is updated like 2 years back.Can anyone please tell me how do I make use of it for Android 2.0.If possible can anyone please mail me latest working Smack jar files. Thanks, Ameya

From the docs I gather that the NSAppearance class and a related protocol NSAppearanceCustomization Appear to be a means of customizing the appearance of NSView and its descendants. An NSAppearance object represents a file that specifies a standard or custom appearance that applies to a subset of UI elements in an app. An app can contain multiple appearance files and—because NSAppearance conforms to NSCoding—you can use Interface Builder to assign UI elements to an appearance. Typically, you customize a window by using Xcode to create an appearance file that contains the views you want to customize and the custom art that should be applied to them. Xcode transforms the file’s art content into a runtime format that AppKit can draw when the specified views are displayed. Well that all sounds neat and promising, but nowhere in the documentation can I find what an appearance file is or how to make one. Google searches are coming up empty other than for the thin documentation I have already read. I do see that UIKit has a similar sounding UIAppearance class, but from what I can tell this is not a straight port of the UIKit class. Does anybody know how to make this magic "appearance file" and what exactly we can do with it?

  • Advice for last year college graduates

    - by Tomh
    Hey guys, I know there are many "advice" questions around this site. But I wanted to to narrow mine down to last year college students, in my case my last year as Master student in computer science. So far is a list of things I've done during my time in college (which I can recommend others to do aswell): Code a lot I've written several hobby projects, had part time jobs, entered the Imagine cup from Microsoft, took programming extensive courses and did freelance gigs. Read a lot I've bought most top books from the recommended book topics here, to be honest I have not read them all. learn different languages I've tried several languages including Haskell, Java, Python, Ruby, Lisp, Prolog, C#, PHP, JS, AS3 and possibly some more I forgot. Tried to start a blog Joel recommends to learn how to write, I tried starting a couple of blogs to improve upon this, I gave up on all instances after writing about three posts. It was just not my thing... Have a portfolio of launched projects/programs I'm busy with this, have a couple of finished, working projects I worked on to show to people. So this is my last year. Is there anything else you can recommend a last year college student to do before hitting the job market? Personally I'm tempted to spend my time on the following: Practice algorithm design Learn and memorize the usage of the low level API's of your favorite language Polish your portfolio Why? Because those first two will make sure you pass the majority of the interviews, here in Holland (I could be wrong). I rather not spend my time on those first two points, but I have to be realistic and thats just my experience on what kind of questions you'll get when you apply. The third point is my hope that I won't have to answer questions about the amount of standard types in c# for example if they can see I get projects done and launched. But I'm still graduating, so I don't know anything :), and many of you might be hiring grads on a recent base and could tell me and other interested people what you wish that the recent grads you interviewed would have done before they applied.

  • Generate JSON object with transactionReceipt

    - by Carlos
    Hi, I've been the past days trying to test my first in-app purchse iphone application. Unfortunately I can't find the way to talk to iTunes server to verify the transactionReceipt. Because it's my first try with this technology I chose to verify the receipt directly from the iPhone instead using server support. But after trying to send the POST request with a JSON onbject created using the JSON api from google code, itunes always returns a strange response (instead the "status = 0" string I wait for). Here's the code that I use to verify the receipt: - (void)recordTransaction:(SKPaymentTransaction *)transaction { NSString *receiptStr = [[NSString alloc] initWithData:transaction.transactionReceipt encoding:NSUTF8StringEncoding]; NSDictionary *jsonDictionary = [NSDictionary dictionaryWithObjectsAndKeys:@"algo mas",@"receipt-data",nil]; NSString *jsonString = [jsonDictionary JSONRepresentation]; NSLog(@"string to send: %@",jsonString); NSLog(@"JSON Created"); urlData = [[NSMutableData data] retain]; //NSURL *sandboxStoreURL = [[NSURL alloc] initWithString:@"https://sandbox.itunes.apple.com/verifyReceipt"]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"https://sandbox.itunes.apple.com/verifyReceipt"]]; [request setHTTPMethod:@"POST"]; [request setHTTPBody:[jsonString dataUsingEncoding:NSUTF8StringEncoding]]; NSLog(@"will create connection"); [[NSURLConnection alloc] initWithRequest:request delegate:self]; } maybe I'm forgetting something in the request's headers but I think that the problem is in the method I use to create the JSON object. HEre's how the JSON object looks like before I add it to the HTTPBody : string to send: {"receipt-data":"{\n\t\"signature\" = \"AUYMbhY ........... D0gIjEuMCI7Cn0=\";\n\t\"pod\" = \"100\";\n\t\"signing-status\" = \"0\";\n}"} The responses I've got: complete response { exception = "java.lang.IllegalArgumentException: Property list parsing failed while attempting to read unquoted string. No allowable characters were found. At line number: 1, column: 0."; status = 21002; } Thanks a lot for your guidance.

  • Bluetooth development on Windows mobile 6 C#

    - by cheesebunz
    Hi everyone, i recently started on a project which is a puzzle slider game. This application will be using the Bluetooth, and i'm working on the mobile,Samsung omnia i900. This is how my application will work. Any user with this Samsung device plays the game and starts sliding the tiles. There is an option to search and connect to other users with the same device and application, so that they can solve the puzzle together. Right now, i'm working on the Bluetooth Part but am still new to the API. I'm using the 32feet.NET inthehandpersonal.net class library while encountering much difficulties. I am able to search for devices by using: private void btnSearch_Click(object sender, EventArgs e) { BluetoothRadio.PrimaryRadio.Mode = RadioMode.Discoverable; BluetoothRadio myRadio = BluetoothRadio.PrimaryRadio; lblSearch.Text = "" + myRadio.LocalAddress.ToString(); bluetoothClient = new BluetoothClient(); Cursor.Current = Cursors.WaitCursor; BluetoothDeviceInfo[] bluetoothDeviceInfo = { }; bluetoothDeviceInfo = bluetoothClient.DiscoverDevices(10); comboBox1.DataSource = bluetoothDeviceInfo; comboBox1.DisplayMember = "DeviceName"; comboBox1.ValueMember = "DeviceAddress"; comboBox1.Focus(); Cursor.Current = Cursors.Default; } Well, to be honest this is a rip off from some sources i found on the internet but i do understand this part. Next i went on to trying to sending a simple "testing.txt" file and i'm stucked at it. I think i will be using something like the OBEX and Obexwebrequest, obexwebresponse, Uri etc. Could anyone explain it in simple terms for me so that i could understand what they are so that i could continue pairing and etc on Bluetooth development. Sorry making it this long, really appreciate if anyone did waste some time reading it :). Hope alanM sees this :) i'm using their bluetooth library.

  • iPhone Development - CLLocationManager vs. MapKit

    - by Mustafa
    If i want to show userLocation on the map, and at the same time record the user's location, is it a good idea to add an observer to userLocation.location and record the locations, OR should i still use CLLocationManager for recording user location and use mapView.showUserLocation to show the user's current location (blue indicator)? I want to show the default blue indicator supported by the MapKit API. Also, here's a rough sample code: - (void)viewDidLoad { ... locationManager = [[CLLocationManager alloc] init]; locationManager.desiredAccuracy = kCLLocationAccuracyBest; locationManager.distanceFilter = DISTANCE_FILTER_VALUE; locationManager.delegate = self; [locationManager startUpdatingLocation]; myMapView.showUserLocation = YES; [myMapView addObserver:self forKeyPath:@"userLocation.location" options:0 context:nil]; ... } - (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context { // Record the location information // ... } - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { NSLog(@"%s begins.", __FUNCTION__); // Make sure that the location returned has the desired accuracy if (newLocation.horizontalAccuracy <= manager.desiredAccuracy) return; // Record the location information // ... } Under the hood, i think MKMapView also uses CLLocationManager to get user's current location? So, will this create any problems because i believe both CLLocationManager and MapView will try to use same location services? Will there be any conflicts and lack of accurate/required or current data?

  • Cannot add Authorization field to HttpsUrlConnection in order to complete Basic authentication

    - by ES
    Hi, I'm using the Sun API HttpsURLConnection class, and have been trying for a day now to get it to send a simple request: URL url = new URL("https://thirdpartyserver.com/somelocation"); connection = (HttpsURLConnection)url.openConnection(); connection.setDoOutput(true); connection.setRequestMethod("POST"); if (doAuthorization) { Base64Converter converter = new Base64Converter(); connection.setRequestProperty("Authorization", "Basic " + converter.encode("username:password")); } OutputStreamWriter writer = new OutputStreamWriter(connection.getOutputStream()); writer.write("param1=100&param2=hello"); writer.flush(); writer.close(); I keep getting 401 from the third part server. When I look at the connection through the debugger, the method shows up as GET even though I set it to POST; the collection of request properties shows up as null. If I print the values out, the method shows up as POST, but the request parameters collection is still empty. I would love to be able to print the request and understand what's going on, but I could not figure out how to print the content of an output buffer. Any ideas? Thanks! ES
