  • Convert XMLDocument to String

    - by mnh
    Here is how I'm currently converting XMLDocument to String StringWriter stringWriter = new StringWriter(); XmlTextWriter xmlTextWriter = new XmlTextWriter(stringWriter); xmlDoc.WriteTo(xmlTextWriter); return stringWriter.ToString(); The problem with this method is that if I have " ((quotes) which I have in attributes) it escapes them. For Instance: <Campaign name="ABC"> </Campaign> Above is the expected XML. But it returns <Campaign name=\"ABC\"> </Campaign> I can do String.Replace "\" but is that method okay? Are there any side-effects? Will it work fine if the XML itself contains a "\"

  • RPX API Call auth_info is returning "missing parameter" error

    - by James Lawruk
    I cannot get the RPX auth_info API call to work. It keeps returning the error: "Missing parameter: apiKey" I am using the C# RPX Helper Class provided on their Wiki:RPX Helper Class Below is my code in my Page_Load method. The RPX service works by sending a POST to a Url that I specify. My code gets the token from the post data shown below. Then I call the AuthInfo API method. string token = Request.Params["token"]; string apiKey = "xxxxxxxxxxxxxxx"; //my API key Rpx rpx = new Rpx(apiKey, "http://rpxnow.com"); XmlElement xmlElement = rpx.AuthInfo(token); Everything looks good. The token is populated. Within their code, the "apiKey" value pair is added to the post data written to the Request stream. Has anyone had luck with this? Any ideas why this is not working? Thanks.

  • How do I give each test its own TestResults folder?

    - by izb
    I have a set of unit tests, each with a bunch of methods, each of which produces output in the TestResults folder. At the moment, all the test files are jumbled up in this folder, but I'd like to bring some order to the chaos. Ideally, I'd like to have a folder for each test method. I know I can go round adding code to each test to make it produce output in a subfolder instead, but I was wondering if there was a way to control the output folder location with the Visual Studio unit test framework, perhaps using an initialization method on each test class so that any new tests added automatically get their own output folder without needing copy/pasted boilerplate code?

  • What is the difference among NSString alloc:initWithCString versus stringWithUTF8String?

    - by mobibob
    I thought these two methods were (memory allocation-wise) equivalent, however, I was seeing "out of scope" and "NSCFString" in the debugger if I used what I thought was the convenient method (commented out below) and when I switched to the more explicit method my code stopped crashing! Notice that I am getting the string that is being stored in my container from sqlite3 query. p = (char*) sqlite3_column_text (queryStmt, 1); // GUID = (NSString*) [NSString stringWithUTF8String: (p!=NULL) ? p : ""]; GUID = [[NSString alloc] initWithCString:(p!=NULL) ? p : "" encoding:NSUTF8StringEncoding]; Also note, that if I looked at the values in the debugger and printed them with NSLog they looked correct, however, I don't think new memory was allocated and the value copied. Instead the memory pointer was stored - went out of scope - referenced later - crash!

  • JDBC Realm: GlassFish v2.1 = OK; GlassFish v3 = fail with invaliduserreason

    - by Vik Gamov
    In my J2EE 5 application I have a JDBC Realm based security with Form method. Encrypt method is MD5 as default. The database is PostgreSQL 8.4 installed locally (or 8.3 available via lan). My app used to work finely on GlassFish v2.1 server with PostgreSQL 8.3, but now I need to deploy it on GlassFish v3. I am absolutely sure I have done all the same config on GFv3 like creating Connection Pool (which pings with no problem), JDBC Resource and JDBC Realm. But on GFv3 I get login exception with "invaliduserreason" while the database schema is just created from the working database script. I have checked the data and entered login/password thousand times and it seems that data is all right. So where can I find the reason of unworking security? Please, advice. NetBeans 6.8 Thanks.

  • How to dispose data context after usage

    - by Erwin
    Hi fellow programmer I have a member class that returned IQueryable from a data context public static IQueryable<TB_Country> GetCountriesQ() { IQueryable<TB_Country> country; Bn_Master_DataDataContext db = new Bn_Master_DataDataContext(); country = db.TB_Countries .OrderBy(o => o.CountryName); return country; } As you can see I don't delete the data context after usage. Because if I delete it, the code that call this method cannot use the IQueryable (perhaps because of deferred execution?). How to force immediate execution to this method? So I can dispose the data context.. Thank you :D

  • Intel mobile CPU power consumption at idle levels?

    - by Ivan Petrushev
    I was wondering if someone has observations (or specifications) of different mobile processors power consumption levels when idle? Let's define 'idle' with 'browsing web sites trough wifi, no flash, no multitasking'. There are different series processors, recognizable by their first letter. The letter tells about the maximum TDP. For example: T - 30-39W P - max 25W L - 12-19W U - <12W However this is about maximum consumptions during load. Is there any difference in power levels when the CPU is idling?

  • Spitting out a Index view using parameters

    - by George
    Hello guys. I'm using ASP.MVC and trying to learn... I have the following controller // get all authors public ActionResult Index() { var autores = autorRepository.FindAllAutores(); return View("Index", autores); } // get authors by type public ActionResult Index(int id) { var autores = autorRepository.FindAllAutoresPorTipo(id); return View("Index", autores); } If i try http://server/Autor/1 I get a 404 error. Why is that? I even tried to create a specific method ListByType(int id) and the correspondent view, but that does not work too (URL: http://server/Autor/ListByType/1) Any ideas? Thanks in advanced EDIT Oh, the http://server/Autor works just fine. The method without parameters is spitting out my view correctly.

  • iphone OCMockObject and unit-testing a class that inherits from NSURLConnection

    - by Justin Galzic
    I want to unit test the custom init method of a class that inherits from NSURLConnection -- how would I do this if the init of my testable class invokes NSURLConnection's initWithRequest? I'm using OCMock and normally, I can mock objects that are contained within my test class. For this inheritance scenario, what's the best approach to do this? - (void)testInit { id urlRequest = [OCMockObject mockForClass:[NSURLRequest class]]; MyURLConnectionWrapper *conn = [[MyURLConnectionWrapper alloc] initWithRequest:urlRequest delegate:self someData:extraneousData]; } My class is implemented like this: @interface MyURLConnectionWrapper : NSURLConnection { } - (id)initWithRequest:(NSURLRequest *)request delegate:(id)delegate someData:(NSString *)fooData @end @implementation MyURLConnectionWrapper - (id)initWithRequest:(NSURLRequest *)request delegate:(id)delegate someData:(NSString *)fooData { if (self = [super initWithRequest:request delegate:delegate]) { // do some additional work here } return self; } Here's the error I get: OCMockObject[NSURLRequest]: unexpected method invoked: _CFURLRequest

  • Problem with JSON, Struts 2 and Ajax.

    - by Javi
    Hello, I have an apllication with Struts 2, Spring and I want to send JSON as a response to an Ajax request, but my server in not sending the JSON in the response. I have this base package: <package name="myApp-default" extends="struts-default"> <result-types> <result-type name="tiles" class="org.apache.struts2.views.tiles.TilesResult" /> <result-type name="json" class="com.googlecode.jsonplugin.JSONResult"> <param name="enableGZIP">true</param> <param name="noCache">true</param> <param name="defaultEncoding">ISO-8859-1</param> </result-type> </result-types> </package> And another package which extends the previous one. <package namespace="/rest" name="rest" extends="myApp-default"> <action name="login" class="restAction" method="login"> <result type="json"/> </action> So I call with jQuery Ajax and debugging it I see it enters in the Action restAction in the method login and it also enters in the method getJsonData() because I have set two breakpoints and the program is stopped first in login and then in getJsonData. public class RestAction extends BaseAction { private String login; private String password; private String jsonData; public String login() { jsonData = "changed"; return Action.SUCCESS; } //I ommit getter/setters for login and password @JSON(name="jsonData") public String getJsonData() { return jsonData; } public void setJsonData(String jsonData) { this.jsonData = jsonData; } } My ajax looks like this: $.ajax({type: 'GET', url: this_url, data: pars, cache:false, success: handleResponse, error: handleError}); With firebug I see that the response to my request is completely void (though I have seen that the data saved in pars variable has been populated to the action and the methods have been executed correctly). And maybe for that reason my ajax enters in my handleError function where xmlHttpRequest.readyState is 4 and xmlHttpRequest.status is 0. Can anyone tell me what may the problem be? Thanks.

  • CALayer and Quartz Transparency

    - by Brian
    I have a CALayer subclass. I have overridden the drawInContext method. I want the majority of my layer to be transparent except a few areas. I'm using the layer as a menu and I want the icons and labels on the menu to be opaque. Is it possible to have a CALayer's sublayers be opaque if the super CALayer is transparent? Is it possible to draw opaque tems in the drawInContext method of a transparent CALayer? I have tried using CGContextSetAlpha, but I assume it doesn't work since the CALayer that I am drawing for is transparent. As always, any help would be great.

  • Out of memory error in java

    - by Anuj
    I am getting OutOfMemoryError: java heap snippets of the method: { // step 1: I am creating a 2 dim array int totalCombination = (int) Math.pow(2.0, (double) vowelCount); here vowelCount > 10 // step2: initializing my array // step3: and using that array } My Question: each time this method is called, that array is getting created. Is it possible that the array is not getting released . In windows taskmanager i can see memory used by java is purely incremental. So it is not that at a point heap size is less, but memory is repetitively used and not released somehow. Please let me know if you need more detal. Please help to debug the error. Anuj

  • Lock Free Queue -- Single Producer, Multiple Consumers

    - by Shirish
    Hello, I am looking for a method to implement lock-free queue data structure that supports single producer, and multiple consumers. I have looked at the classic method by Maged Michael and Michael Scott (1996) but their version uses linked lists. I would like an implementation that makes use of bounded circular buffer. Something that uses atomic variables? On a side note, I am not sure why these classic methods are designed for linked lists that require a lot of dynamic memory management. In a multi-threaded program, all memory management routines are serialized. Aren't we defeating the benefits of lock-free methods by using them in conjunction with dynamic data structures? I am trying to code this in C/C++ using pthread library on a Intel 64-bit architecture. Thank you, Shirish

  • Eclipse IDE's Hello World Cheatsheet seems to have a mistake

    - by Sean
    Hey guys, Just a warning: I'm completely new to Java and am trying to teach myself Android programming. I installed the Eclipse IDE today and tried to walk through the first Java Hello World "cheat sheet," and it didn't work! I was really quite surprised. When it asked me to select the checkbox to create the main() method, there wasn't anything on-screen that looked like a checkbox with "main()" or "method" next to it, so I guessed that maybe what they meant was the "Modifiers" radio button. So I left that checked for "public." It didn't compile and I got red X's next to every folder in my Package Explorer. Has anybody else had this problem? Thanks!

  • WebOrb - Serializing an object as a string

    - by Robert Wagner
    We have an Adobe Flex client talking to a .NET server using WebORB. Simplifying things, on the .NET side of things we have a struct that wraps a ulong like this: public struct MyStruct { private ulong _val; public override string ToString() { return _val.ToString("x16"); } // Parse method } I want the Flex client to treat this as a string. So that for the following server method: public void DoStuff(int i, MyStruct b); It can call it as DoStuff(1, "1234567890ABCDEF") I've tried playing with custom WebORB serializers, but the documentation is a bit scarce. Is this possible? If so how?

  • Android: onClick on LinearLayout with TextView and Button

    - by Terry
    I have a Fragment that uses the following XML layout: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/card" android:clickable="true" android:onClick="editActions" android:orientation="vertical" > <TextView android:id="@+id/title" style="@style/CardTitle" android:layout_width="wrap_content" android:layout_height="wrap_content" android:duplicateParentState="true" android:text="@string/title_workstation" /> <Button android:id="@+id/factory_button_edit" style="?android:attr/buttonStyleSmall" android:layout_width="wrap_content" android:layout_height="wrap_content" android:duplicateParentState="true" android:text="@string/label_edit" /> </LinearLayout> As you can see, I have an onClick parameter set on LinearLayout. Now on the TextView this one is triggered correctly, and on all empty area. Just on the Button it doesn't invoke the onClick method that I set. Is this normal? What do I have to do so that the onClick method is invoked everywhere on the LinearLayout?

  • Why does python use 'magic methods'?

    - by Greg Beech
    I've been playing around with Python recently, and one thing I'm finding a bit odd is the extensive use of 'magic methods', e.g. to make its length available an object implements a method def __len__(self) and then it is called when you write len(obj). I was just wondering why objects don't simply define a len(self) method and have it called directly as a member of the object, e.g. obj.len()? I'm sure there must be good reasons for Python doing it the way it does, but as a newbie I haven't worked out what they are yet.

  • Objective-C : Trouble with file download

    - by Holli
    I ran in a bit of trouble downloading files with Objective-C. I use the download decideDestinationWithSuggestedFilename from Apples documentation page. http://developer.apple.com/mac/library/documentation/cocoa/conceptual/URLLoadingSystem/Tasks/UsingNSURLDownload.html As long as I want to download just one file it works fine but I want to download an array for files one by one. The problem starts with the second file. Right now my code will trigger the next download itself from the downloadDidFinish Method. Then I will get an unrecognized selector sent to instance error. For me it looks like the NSURLDownload that just finished the download is still in use somehow. Release is called but the must be a problem. If I just put an NSBeep in the downloadDidFinished Method and trigger the next file download manually it works fine. Looks like I have to wait a while till I can start the next download. I know this question is a bit vague but maybe someone got an idea.

  • Using mergedModelFromBundles: and versioning (CoreData)

    - by charlax
    Hi everybody, I'm trying to use the migration feature in CoreData. I've followed the Apple Documentation. I have a problem in the following method: /** Returns the managed object model for the application. If the model doesn't already exist, it is created by merging all of the models found in the application bundle. */ - (NSManagedObjectModel *)managedObjectModel { if (managedObjectModel != nil) { return managedObjectModel; } /* * NSInvalidArgumentException', reason: '*** -[NSCFArray insertObject:atIndex:]: attempt to insert nil' * 2010-02-17 16:27:15.338 Patrimoine[3037:207] */ managedObjectModel = [[NSManagedObjectModel mergedModelFromBundles:nil] retain]; return managedObjectModel; } It appears that there is the same problem on http://iphonedevelopment.blogspot.com/2009/09/core-data-migration-problems.html Yet I did choose the method Apple suggests, by using the menu option "Add Model Version". Do you have any idea?

  • iPhone - Is it ok to override UITableViewCell setSelected:animated

    - by Brian
    I am drawing custom UITableViewCells. My cells are opaque and are completely drawn in the drawRect of the cell to help with performance. I want to handle the look of a selected cell myself. If I don't, then the contents of my cell is covered up by the selectedBackgroundView that is added. Is it common or acceptable to override the setSelected:animated method of my cell so this is done properly. I guess if I did that, then I would not call the super's setSelected method since I would be handling how the cell will show that its selected. I would also have to set the selected property of the cell. Any help would be great. Thanks.

  • linq Except and custom IEqualityComparer

    - by Joe
    I'm trying to implement a custom comparer on two lists of strings and use the .Except() linq method to get those that aren't one one of the lists. The reason I'm doing a custom comparer is because I need to do a "fuzzy" compare, i.e. one string on one list could be embedded inside a string on the other list. I've made the following comparer ` public class ItemFuzzyMatchComparer : IEqualityComparer { bool IEqualityComparer<string>.Equals(string x, string y) { return (x.Contains(y) || y.Contains(x)); } int IEqualityComparer<string>.GetHashCode(string obj) { if (Object.ReferenceEquals(obj, null)) return 0; return obj.GetHashCode(); } } ` When I debug, the only breakpoint that hits is in the GetHashCode() method. The Equals() never gets touched. Any ideas?

  • JAVA Classes in Game programming.

    - by Gabriel A. Zorrilla
    I'm doing a little strategy game to help me learn Java in a fun way. The thing is I visioned the units as objects that would self draw on the game map (using images and buffering) and would react to the mouse actions with listeners attached to them. Now, based on some tutorials I've been reading regarding basic game programming, all seems to be drawn in the Graphics method of my Map class. If a new unit emerges, i just update the Map.Graphics method, it's not as easy as making a new Unit object which would self draw... In this case, I'd be stuck with a whole bunch of Map methods instead of using classes for rendering new things. So my question is, is it possible to use classes for rendering units, interface objects, etc, or i'll have to create methods and just do some kind of structural programming instead of object oriented? I'm a little bit confused and I'd like to have a mental blueprint of how things would be organized. Thanks!
