  • WCF App using Peer Chat app as example does not work.

    - by splate
    I converted a VB .Net 3.5 app to use peer to peer WCF using the available Microsoft example of the Chat app. I made sure that I copied the app.config file for the sample(modified the names for my app), added the appropriate references. I followed all the tutorials and added the appropriate tags and structure in my app code. Everything runs without any errors, but the clients only get messages from themselves and not from the other clients. The sample chat application does run just fine with multiple clients. The only difference I could find is that the server on the sample is targeting the framework 2.0, but I assume that is wrong and it is building it in at least 3.0 or the System.ServiceModel reference would break. Is there something that has to be registered that the sample is doing behind the scenes or is the sample a special project type? I am confused. My next step is to copy all my classes and logic from my app to the sample app, but that is likely a lot of work. Here is my Client App.config: <client><endpoint name="thldmEndPoint" address="net.p2p://thldmMesh/thldmServer" binding="netPeerTcpBinding" bindingConfiguration="PeerTcpConfig" contract="THLDM_Client.IGameService"></endpoint></client> <bindings><netPeerTcpBinding> <binding name="PeerTcpConfig" port="0"> <security mode="None"></security> <resolver mode="Custom"> <custom address="net.tcp://localhost/thldmServer" binding="netTcpBinding" bindingConfiguration="TcpConfig"></custom> </resolver> </binding></netPeerTcpBinding> <netTcpBinding> <binding name="TcpConfig"> <security mode="None"></security> </binding> </netTcpBinding> </bindings> Here is my server App.config: <services> <service name="System.ServiceModel.PeerResolvers.CustomPeerResolverService"> <host> <baseAddresses> <add baseAddress="net.tcp://localhost/thldmServer"/> </baseAddresses> </host> <endpoint address="net.tcp://localhost/thldmServer" binding="netTcpBinding" bindingConfiguration="TcpConfig" contract="System.ServiceModel.PeerResolvers.IPeerResolverContract"> </endpoint> </service> </services> <bindings> <netTcpBinding> <binding name="TcpConfig"> <security mode="None"></security> </binding> </netTcpBinding> </bindings> Thanks ahead of time.

  • Boxy Submit Form

    - by jornbjorndalen
    I am using the boxy jQuery plugin in my page to display a form on a clickEvent for the fullCalendar plugin. It is working all right , the only problem I have is that the form in boxy brings up the confirmation dialog the first time the dialog is opened and when the user clicks "Ok" it submits the form a second time which generates 2 events on my calendar and 2 entries in my database. My code looks like this inside fullCalendar: dayClick: function(date, allDay, jsEvent, view) { var day=""+date.getDate(); if(day.length==1){ day="0"+day; } var year=date.getFullYear(); var month=date.getMonth()+1; var month=""+month; if(month.length==1){ month="0"+month; } var defaultdate=""+year+"-"+month+"-"+day+" 00:00:00"; var ele = document.getElementById("myform"); new Boxy(ele,{title: "Add Task", modal: true}); document.getElementById("title").value=""; document.getElementById("description").value=""; document.getElementById("startdate").value=""+defaultdate; document.getElementById("enddate").value=""+defaultdate; } I also use validators on the forms fields: $.validator.addMethod( "datetime", function(value, element) { // put your own logic here, this is just a (crappy) example return value.match(/^([0-9]{4})-([0-1][0-9])-([0-3][0-9])\s([0-1][0-9]|[2][0-3]):([0-5][0-9]):([0-5][0-9])$/); }, "Please enter a date in the format YYYY-mm-dd hh:MM:ss" ); var validator=$("#myform").validate({ onsubmit:true, rules: { title: { required: true }, startdate: { required: true, datetime: true }, enddate: { required: true, datetime: true } }, submitHandler: function(form) { //this function renders a new event and makes a call to a php script that inserts it into the db addTask(form); } }); And the form looks like this: <form id ='myform'> <table border='1' width='100%'> <tr><td align='right'>Title:</td><td align='left'><input id='title' name='title' size='30'/></td></tr> <tr><td align='right'>Description:</td><td align='left'><textarea id='description' name='description' rows='4' cols='30'></textarea></td></tr> <tr><td align='right'>Start Date:</td><td align='left'><input id='startdate' name='startdate' size='30'/></td></tr> <tr><td align='right'>End Date:</td><td align='left'><input id='enddate' name='enddate' size='30' /></td></tr> <tr><td colspan='2' align='right'><input type='submit' value='Add' /></td></tr> </table> </form>

  • Distinguishing between failure and end of file in read loop

    - by celtschk
    The idiomatic loop to read from an istream is while (thestream >> value) { // do something with value } Now this loop has one problem: It will not distinguish if the loop terminated due to end of file, or due to an error. For example, take the following test program: #include <iostream> #include <sstream> void readbools(std::istream& is) { bool b; while (is >> b) { std::cout << (b ? "T" : "F"); } std::cout << " - " << is.good() << is.eof() << is.fail() << is.bad() << "\n"; } void testread(std::string s) { std::istringstream is(s); is >> std::boolalpha; readbools(is); } int main() { testread("true false"); testread("true false tr"); } The first call to testread contains two valid bools, and therefore is not an error. The second call ends with a third, incomplete bool, and therefore is an error. Nevertheless, the behaviour of both is the same. In the first case, reading the boolean value fails because there is none, while in the second case it fails because it is incomplete, and in both cases EOF is hit. Indeed, the program above outputs twice the same line: TF - 0110 TF - 0110 To solve this problem, I thought of the following solution: while (thestream >> std::ws && !thestream.eof() && thestream >> value) { // do something with value } The idea is to detect regular EOF before actually trying to extract the value. Because there might be whitespace at the end of the file (which would not be an error, but cause read of the last item to not hit EOF), I first discard any whitespace (which cannot fail) and then test for EOF. Only if I'm not at the end of file, I try to read the value. For my example program, it indeed seems to work, and I get TF - 0100 TF - 0110 So in the first case (correct input), fail() returns false. Now my question: Is this solution guaranteed to work, or was I just (un-)lucky that it happened to give the desired result? Also: Is there a simpler (or, if my solution is wrong, a correct) way to get the desired result?

  • Where do you put your unit test?

    - by soulmerge
    I have found several conventions to housekeeping unit tests in a project and I'm not sure which approach would be suitable for our next PHP project. I am trying to find the best convention to encourage easy development and accessibility of the tests when reviewing the source code. I would be very interested in your experience/opinion regarding each: One folder for productive code, another for unit tests: This separates unit tests from the logic files of the project. This separation of concerns is as much a nuisance as it is an advantage: Someone looking into the source code of the project will - so I suppose - either browse the implementation or the unit tests (or more commonly: the implementation only). The advantage of unit tests being another viewpoint to your classes is lost - those two viewpoints are just too far apart IMO. Annotated test methods: Any modern unit testing framework I know allows developers to create dedicated test methods, annotating them (@test) and embedding them in the project code. The big drawback I see here is that the project files get cluttered. Even if these methods are separated using a comment header (like UNIT TESTS below this line) it just bloats the class unnecessarily. Test files within the same folders as the implementation files: Our file naming convention dictates that PHP files containing classes (one class per file) should end with .class.php. I could imagine that putting unit tests regarding a class file into another one ending on .test.php would render the tests much more present to other developers without tainting the class. Although it bloats the project folders, instead of the implementation files, this is my favorite so far, but I have my doubts: I would think others have come up with this already, and discarded this option for some reason (i.e. I have not seen a java project with the files Foo.java and FooTest.java within the same folder.) Maybe it's because java developers make heavier use of IDEs that allow them easier access to the tests, whereas in PHP no big editors have emerged (like eclipse for java) - many devs I know use vim/emacs or similar editors with little support for PHP development per se. What is your experience with any of these unit test placements? Do you have another convention I haven't listed here? Or am I just overrating unit test accessibility to reviewers?

  • Separation of domain and ui layer in a composite

    - by hansmaad
    Hi all, i'm wondering if there is a pattern how to separate the domain logic of a class from the ui responsibilities of the objects in the domain layer. Example: // Domain classes interface MachinePart { CalculateX(in, out) // Where do we put these: // Draw(Screen) ?? // ShowProperties(View) ?? // ... } class Assembly : MachinePart { CalculateX(in, out) subParts } class Pipe : MachinePart { CalculateX(in, out) length, diamater... } There is an application that calculates the value X for machines assembled from many machine parts. The assembly is loaded from a file representation and is designed as a composite. Each concrete part class stores some data to implement the CalculateX(in,out) method to simulate behaviour of the whole assembly. The application runs well but without GUI. To increase the usability a GUi should be developed on top of the existing implementation (changes to the existing code are allowed). The GUI should show a schematic graphical representation of the assembly and provide part specific dialogs to edit several parameters. To achieve these goals the application needs new functionality for each machine part to draw a schematic representation on the screen, show a property dialog and other things not related to the domain of machine simulation. I can think of some different solutions to implement a Draw(Screen) functionality for each part but i am not happy with each of them. First i could add a Draw(Screen) method to the MachinePart interface but this would mix-up domain code with ui code and i had to add a lot of functionality to each machine part class what makes my domain model hard to read and hard to understand. Another "simple" solution is to make all parts visitable and implement ui code in visitors but Visitor does not belong to my favorite patterns. I could derive UI variants from each machine part class to add the UI implementation there but i had to check if each part class is suited for inheritance and had to be careful on changes to the base classes. My currently favorite design is to create a parallel composite hierarchy where each component stores data to define a machine part, has implementation for UI methods and a factory method which creates instances of the corresponding domain classes, so that i can "convert" a UI assembly to a domain assembly. But there are problems to go back from the created domain hierarchy to the UI hierarchy for showing calculation results in the drawing for example (imagine some parts store some values during the calculation i want to show in the schematic representation after the simluation). Maybe there are some proven patterns for such problems?

  • Writing a mini-language with haskell, trouble with "while" statements and blocks { }

    - by Nibirue
    EDIT: problem partially solved, skip to the bottom for update. I'm writing a small language using haskell, and I've made a lot of progress, but I am having trouble implementing statements that use blocks, like "{ ... }". I've implemented support for If statements like so in my parser file: stmt = skip +++ ifstmt +++ assignment +++ whilestmt ifstmt = symbol "if" >> parens expr >>= \c -> stmt >>= \t -> symbol "else" >> stmt >>= \e -> return $ If c t e whilestmt = symbol "while" >> parens expr >>= \c -> symbol "\n" >> symbol "{" >> stmt >>= \t -> symbol "}" >> return $ While c t expr = composite +++ atomic And in the Syntax file: class PP a where pp :: Int -> a -> String instance PP Stmt where pp ind (If c t e) = indent ind ++ "if (" ++ show c ++ ") \n" ++ pp (ind + 2) t ++ indent ind ++ "else\n" ++ pp (ind + 2) e pp ind (While c t) = indent ind ++ "while (" ++ show c ++") \n" ++ "{" ++ pp (ind + 2) t ++ "}" ++ indent ind Something is wrong with the while statement, and I don't understand what. The logic seems correct, but when I run the code I get the following error: EDIT: Fixed the first problem based on the first reply, now it is not recognizing my while statment which I assume comes from this: exec :: Env -> Stmt -> Env exec env (If c t e) = exec env ( if eval env c == BoolLit True then t else e ) exec env (While c t) = exec env ( if eval env c == BoolLit True then t ) The file being read from looks like this: x = 1; c = 0; if (x < 2) c = c + 1; else ; -- SEPARATE FILES FOR EACH x = 1; c = 1; while (x < 10) { c = c * x; x = x + 1; } c I've tried to understand the error report but nothing I've tried solves the problem.

  • Serialize JavaScript's navigator object

    - by kappa
    Hi, I'm creating a page to help diagnose the problem our users are experiencing with our web pages (you know, asking a user "What browser are you using?" usually leads to "Internet"). This page already submits to me all the HTTP headers and now I'm trying to have JavaScript give some more informations, so I thought it would be great to have the user's navigator JavaScript object and I started looking how to serialize it so I can submit it through a form. The problem is I'm not able to serialize the navigator object using any JSON library I know of, everyone returns an empty object (?!), so I decided to write an ad-hoc serializer. You can find the code here: <!DOCTYPE html> <html> <head> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js" type="text/javascript"></script> <script type="text/javascript"> function serialize (object) { var type = typeof object; if (object === null) { return '"nullValue"'; } if (type == 'string' || type === 'number' || type === 'boolean') { return '"' + object + '"'; } else if (type === 'function') { return '"functionValue"'; } else if (type === 'object') { var output = '{'; for (var item in object) { if (item !== 'enabledPlugin') { output += '"' + item + '":' + serialize(object[item]) + ','; } } return output.replace(/\,$/, '') + '}'; } else if (type === 'undefined') { return '"undefinedError"'; } else { return '"unknownTypeError"'; } }; $(document).ready(function () { $('#navigator').text(serialize(navigator)); }); </script> <style type="text/css"> #navigator { font-family: monospaced; } </style> <title>Serialize</title> </head> <body> <h1>Serialize</h1> <p id="navigator"></p> </body> </html> This code seems to work perfectly in Firefox, Opera, Chrome and Safari but (obviously) doesn't work in Internet Explorer (at least version 8.0), it complains that "Property or method not supported by the object" at line for (var item in object) {. Do you have any hint on how to fix the code or how to reach the goal (serialize the navigator object) by other means?

  • Objective-C memory management issue

    - by Toby Wilson
    I've created a graphing application that calls a web service. The user can zoom & move around the graph, and the program occasionally makes a decision to call the web service for more data accordingly. This is achieved by the following process: The graph has a render loop which constantly renders the graph, and some decision logic which adds web service call information to a stack. A seperate thread takes the most recent web service call information from the stack, and uses it to make the web service call. The other objects on the stack get binned. The idea of this is to reduce the number of web service calls to only those appropriate, and only one at a time. Right, with the long story out of the way (for which I apologise), here is my memory management problem: The graph has persistant (and suitably locked) NSDate* objects for the currently displayed start & end times of the graph. These are passed into the initialisers for my web service request objects. The web service call objects then retain the dates. After the web service calls have been made (or binned if they were out of date), they release the NSDate*. The graph itself releases and reallocates new NSDates* on the 'touches ended' event. If there is only one web service call object on the stack when removeAllObjects is called, EXC_BAD_ACCESS occurs in the web service call object's deallocation method when it attempts to release the date objects (even though they appear to exist and are in scope in the debugger). If, however, I comment out the release messages from the destructor, no memory leak occurs for one object on the stack being released, but memory leaks occur if there are more than one object on the stack. I have absolutely no idea what is going wrong. It doesn't make a difference what storage symantics I use for the web service call objects dates as they are assigned in the initialiser and then only read (so for correctness' sake are set to readonly). It also doesn't seem to make a difference if I retain or copy the dates in the initialiser (though anything else obviously falls out of scope or is unwantedly released elsewhere and causes a crash). I'm sorry this explanation is long winded, I hope it's sufficiently clear but I'm not gambling on that either I'm afraid. Major big thanks to anyone that can help, even suggest anything I may have missed?

  • Vertical Seek not progress value not showing on MainActivity textView

    - by Raju Gujarati
    I am try to display the progress value of the seekBar but when it comes to the execution, there is no update on the value being display on the TextView. I wonder what alternatives than putting two classes onto one big class in order to archive this aim ?

  • C++ Vector vs Array (Time)

    - by vsha041
    I have got here two programs with me, both are doing exactly the same task. They are just setting an boolean array / vector to the value true. The program using vector takes 27 seconds to run whereas the program involving array with 5 times greater size takes less than 1 s. I would like to know the exact reason as to why there is such a major difference ? Are vectors really that inefficient ? Program using vectors #include <iostream> #include <vector> #include <ctime> using namespace std; int main(){ const int size = 2000; time_t start, end; time(&start); vector<bool> v(size); for(int i = 0; i < size; i++){ for(int j = 0; j < size; j++){ v[i] = true; } } time(&end); cout<<difftime(end, start)<<" seconds."<<endl; } Runtime - 27 seconds Program using Array #include <iostream> #include <ctime> using namespace std; int main(){ const int size = 10000; // 5 times more size time_t start, end; time(&start); bool v[size]; for(int i = 0; i < size; i++){ for(int j = 0; j < size; j++){ v[i] = true; } } time(&end); cout<<difftime(end, start)<<" seconds."<<endl; } Runtime - < 1 seconds Platform - Visual Studio 2008 OS - Windows Vista 32 bit SP 1 Processor Intel(R) Pentium(R) Dual CPU T2370 @ 1.73GHz Memory (RAM) 1.00 GB Thanks Amare

  • How should I organize my C# classes? [closed]

    - by oscar.fimbres
    I'm creating an email generator system. I'm creating some clases and I'm trying to make things right. By the time, I have created 5 classes. Look at the class diagram: I'm going to explain you each one. Person. It's not a big deal. Just have two constructors: Person(fname, lname1, lname2) and Person(token, fname, lname1, lname2). Note that email property stays without value. StringGenerator. This is a static class and it has only a public function: Generate. The function receives a Person class and it will return a list of patterns for the email. MySql. It contains all the necessary to connect to a database. Database. This class inherits from MySql class. It has particular functions for the database. This gets all the registries from a table (function GetPeople) and return a List. Each person from the list contains all data except Email. Also it can add records (List but this must contains an available email). An available email is when an email doesn't have another person. For that reason, I have a method named ExistsEmail. Container. This is the class which is causing me some problems. It's like a temporary container. It supposed to have a people list from GetPeople (in Database class) and for each person it adds, it must generate a list of possible names (StringGenerator.Generate), then it selects one of the list and it must check out if exists in the database or in the same container. As I told above this is temporal, it may none of the possible emails is available. So the user can modify or enter a custom email available and update the list in this container. When all the email's people are available, it sends a list to add in the database, It must have a Flush method, to insert all the people in the database. I'm trying to design correct class. I need a little help to improve or edite the classes, because I want to separate the logic and visual, and learn of you. I hope you've been able to understand me. Any question or doubt, please let me know. Anyway, I attached the solution here to better understand it: http://www.megaupload.com/?d=D94FH8GZ

  • How to store array of NSManagedObjects in an NSManagedObject

    - by David Tay
    I am loading my app with a property list of data from a web site. This property list file contains an NSArray of NSDictionaries which itself contains an NSArray of NSDictionaries. Basically, I'm trying to load a tableView of restaurant menu categories each of which contains menu items. My property list file is fine. I am able to load the file and loop through the nodes structure creating NSEntityDescriptions and am able to save to Core Data. Everything works fine and expectedly except that in my menu category managed object, I have an NSArray of menu items for that category. Later on, when I fetch the categories, the pointers to the menu items in a category is lost and I get all the menu items. Am I suppose to be using predicates or does Core Data keep track of my object graph for me? Can anyone look at how I am loading Core Data and point out the flaw in my logic? I'm pretty good with either SQL and OOP by themselves, but am a little bewildered by ORM. I thought that I should just be able to use aggregation in my managed objects and that the framework would keep track of the pointers for me, but apparently not. NSError *error; NSURL *url = [NSURL URLWithString:@"http://foo.com"]; NSArray *categories = [[NSArray alloc] initWithContentsOfURL:url]; NSMutableArray *menuCategories = [[NSMutableArray alloc] init]; for (int i=0; i<[categories count]; i++){ MenuCategory *menuCategory = [NSEntityDescription insertNewObjectForEntityForName:@"MenuCategory" inManagedObjectContext:[self managedObjectContext]]; NSDictionary *category = [categories objectAtIndex:i]; menuCategory.name = [category objectForKey:@"name"]; NSArray *items = [category objectForKey:@"items"]; NSMutableArray *menuItems = [[NSMutableArray alloc] init]; for (int j=0; j<[items count]; j++){ MenuItem *menuItem = [NSEntityDescription insertNewObjectForEntityForName:@"MenuItem" inManagedObjectContext:[self managedObjectContext]]; NSDictionary *item = [items objectAtIndex:j]; menuItem.name = [item objectForKey:@"name"]; menuItem.price = [item objectForKey:@"price"]; menuItem.image = [item objectForKey:@"image"]; menuItem.details = [item objectForKey:@"details"]; [menuItems addObject:menuItem]; } [menuCategory setValue:menuItems forKey:@"menuItems"]; [menuCategories addObject:menuCategory]; [menuItems release]; } if (![[self managedObjectContext] save:&error]) { NSLog(@"An error occurred: %@", [error localizedDescription]); }

  • This code appears to achieve the return of a null reference in C++

    - by Chuck
    Hi folks, My C++ knowledge is somewhat piecemeal. I was reworking some code at work. I changed a function to return a reference to a type. Inside, I look up an object based on an identifier passed in, then return a reference to the object if found. Of course I ran into the issue of what to return if I don't find the object, and in looking around the web, many people claim that returning a "null reference" in C++ is impossible. Based on this advice, I tried the trick of returning a success/fail boolean, and making the object reference an out parameter. However, I ran into the roadblock of needing to initialize the references I would pass as actual parameters, and of course there is no way to do this. I retreated to the usual approach of just returning a pointer. I asked a colleague about it. He uses the following trick quite often, which is accepted by both a recent version of the Sun compiler and by gcc: MyType& someFunc(int id) { // successful case here: // ... // fail case: return *static_cast<MyType*>(0); } // Use: ... MyType& mt = somefunc(myIdNum); if (&mt) // test for "null reference" { // whatever } ... I have been maintaining this code base for a while, but I find that I don't have as much time to look up the small details about the language as I would like. I've been digging through my reference book but the answer to this one eludes me. Now, I had a C++ course a few years ago, and therein we emphasized that in C++ everything is types, so I try to keep that in mind when thinking things through. Deconstructing the expression: "*static_cast(0);", it indeed seems to me that we take a literal zero, cast it to a pointer to MyType (which makes it a null pointer), and then apply the dereferencing operator in the context of assigning to a reference type (the return type), which should give me a reference to the same object pointed to by the pointer. This sure looks like returning a null reference to me. Any advice in explaining why this works (or why it shouldn't) would be greatly appreciated. Thanks, Chuck

  • php functions within functions.

    - by Adamski
    Hi all, ihave created a simple project to help me get to grips with php and mysql, but have run into a minor issue, i have a working solution but would like to understand why i cannot run this code successfully this way, ill explain: i have a function, function fetch_all_movies(){ global $connection; $query = 'select distinct * FROM `'.TABLE_MOVIE.'` ORDER BY movieName ASC'; $stmt = mysqli_prepare($connection,$query); mysqli_execute($stmt); mysqli_stmt_bind_result($stmt,$id,$name,$genre,$date,$year); while(mysqli_stmt_fetch($stmt)){ $editUrl = "index.php?a=editMovie&movieId=".$id.""; $delUrl = "index.php?a=delMovie&movieId=".$id.""; echo "<tr><td>".$id."</td><td>".$name."</td><td>".$date."</td><td>".get_actors($id)."</td><td><a href=\"".$editUrl."\">Edit</a> | <a href=\"".$delUrl."\">Delete</a></td></tr>"; } } this fetches all the movies in my db, then i wish to get the count of actors for each film, so i pass in the get_actors($id) function which gets the movie id and then gives me the count of how many actors are realted to a film. here is the function for that: function get_actors($movieId){ global $connection; $query = 'SELECT DISTINCT COUNT(*) FROM `'.TABLE_ACTORS.'` WHERE movieId = "'.$movieId.'"'; $result = mysqli_query($connection,$query); $row = mysqli_fetch_array($result); return $row[0]; } the functions both work perfect when called separately, i just would like to understand when i pass the function inside a function i get this warning: Warning: mysqli_fetch_array() expects parameter 1 to be mysqli_result, boolean given in /Applications/MAMP/htdocs/movie_db/includes/functions.inc.php on line 287 could anyone help me understand why? many thanks.

  • Remove Item From Object SubList (LINQ)

    - by X3074861X
    I have an object that looks like this : public class Consortium { public string Id { get; set; } [JsonConverter(typeof(EnumDescriptionConverter))] public SourceType Type { get; set; } public List<UserLibrary> Branches { get; set; } } Each Consortium has a list of UserLibrary's associated with it, and that class looks like this : public class UserLibrary { public string LibraryId { get; set; } public string RetailerId {get; set;} public string UserId { get; set; } public string Name { get; set; } public DateTime CreatedAt { get; set; } } I have a method which will allow the user to remove a library from one of their consortium (note: There may be many branches associated to the consortium). However, I'm only being supplied a LibraryId, so I'm forced to traverse their list of Consortium, find which one contains the given id, then iterate over the branches and remove the one that matches the id. Here is how I'm currently accomplishing this : // Get the current list of consortiums var user = _mediator.Send(new GetUserProfileCommand { UserProfileId = _principle.UserProfileId }); var userConsortia = user.SavedConsortia; // the consortium to remove the library from var branchToRemove = _libraryService.GetLibrary(id); var consortRemove = new UserConsortium(); foreach (var userConsortium in userConsortia) { if (userConsortium.Branches.FirstOrDefault(c => string.Equals(c.LibraryId, id, StringComparison.OrdinalIgnoreCase)) != null) { consortRemove = userConsortium; } } // if the consortium id is null, something is f* if (consortRemove.Id == null) { return new JsonDotNetResult(HttpStatusCode.BadRequest); } // first remove the consortia userConsortia.Remove(consortRemove); // remove the branch from the consortium consortRemove.Branches.RemoveAll(ul => string.Equals(ul.LibraryId, id, StringComparison.OrdinalIgnoreCase)); // add it back in without the branch userConsortia.Add(consortRemove); Question : Is there a LINQ expression I'm missing here that can help me consolidate this logic, or is there a better way of doing this?

  • Unlock device, display a text, then lock again

    - by Waza_Be
    For the need of my application, I need to display a message on the screen even if the lockscreen is enabled, then wait 3 seconds, than I have to lock again the phone as I don't want it to make unwanted phone calls in your pockets. First part is easy: if (PreferenceManager.getDefaultSharedPreferences( getBaseContext()).getBoolean("wake", false)) { KeyguardManager kgm = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE); boolean isKeyguardUp = kgm.inKeyguardRestrictedInputMode(); WakeLocker.acquire(ProtoBenService.this); Intent myIntent = new Intent(ProtoBenService.this,LockActivity.class); myIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); if (isKeyguardUp) { ProtoBenService.this.startActivity(myIntent); } else Toast.makeText(ProtoBenService.this.getBaseContext(), intention, Toast.LENGTH_LONG).show(); WakeLocker.release(); } With this class: public abstract class WakeLocker { private static PowerManager.WakeLock wakeLock; public static void acquire(Context ctx) { if (wakeLock != null) wakeLock.release(); PowerManager pm = (PowerManager) ctx.getSystemService(Context.POWER_SERVICE); wakeLock = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.ON_AFTER_RELEASE, "CobeIm"); wakeLock.acquire(); } public static void release() { if (wakeLock != null) wakeLock.release(); wakeLock = null; } } And the Activity: public class LockActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Window window = getWindow(); window.addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD); window.addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON); window.addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); TextView tv = new TextView(this); tv.setText("This is working!"); tv.setTextSize(45); setContentView(tv); Runnable mRunnable; Handler mHandler = new Handler(); mRunnable = new Runnable() { @Override public void run() { LockActivity.this.finish(); } }; mHandler.postDelayed(mRunnable, 3 * 1000); } } So, this is nice, the phone can display my text! The only problem comes when I want to lock again the phone, it seems that locking the phone is protected by the system... Programmatically turning off the screen and locking the phone how to lock the android programatically I think that my users won't understand the Device Admin and won't be able to activate it. Is there any workaround to lock the screen without the Device Admin stuff?

  • Java - Layering issues with Lists and Graphics2D

    - by Mirrorcrazy
    So I have a DisplayPanel class that extends JPanel and that also paints my numerous images for my program using Graphics2D. In order to be able to easily customly use this I set it up so that every time the panel is repainted it uses a List, that I can add to or remove from as the program processes. My problem is with layering. I've run into an issue where the List must have reached its resizing point (or something whacky like that) and so the images i want to display end up beneath all of the other images already on the screen. I've come to the community for an answer because I have faith you will provide a good one. DisplayPanel: package earthworm; import java.awt.Graphics; import java.awt.Graphics2D; import java.util.ArrayList; import java.util.List; import javax.swing.JPanel; public class DisplayPanel extends JPanel { private List<ImageMap> images = new ArrayList(); public DisplayPanel() { setSize(800, 640); refresh(); } public void refresh() { revalidate(); repaint(); } @Override public void paintComponent(Graphics g) { super.paintComponent(g); Graphics2D g2d = (Graphics2D) g; g2d.clearRect(0, 0, 800, 640); for(int i = 0; i < images.size(); i++) g2d.drawImage( images.get(i).getImage(), images.get(i).getX(), images.get(i).getY(), null); } public void paintImage(ImageMap[] images, ImageMap[] clearImages, boolean clear) { if(clear) this.images.clear(); else if(clearImages!=null) for(int i = 0; i < clearImages.length; i++) this.images.remove(clearImages[i]); if(images!=null) for(int i = 0; i<images.length; i++) this.images.add(images[i]); refresh(); } }

  • PHP Based session variable not retaining value. Works on localhost, but not on server.

    - by Foo
    I've been trying to debug this problem for many hours, but to no avail. I've been using PHP for many years, and got back into it after long hiatus, so I'm still a bit rusty. Anyways, my $_SESSION vars are not retaining their value for some reason that I can't figure out. The site worked on localhost perfectly, but uploading it to the server seemed to break it. First thing I checked was the PHP.ini server settings. Everything seems fine. In fact, my login system is session based and it works perfectly. So now that I know $_SESSIONS are working properly and retaining their value for my login, I'm presuming the server is setup and the problem is in my script. Here's a stripped version of the code that's causing a problem. $type, $order and $style are not being retained after they are set via a GET variable. The user clicks a link, which sets a variable via GET, and this variable is retained for the remainder of their session. Is there some problem with my logic that I'm not seeing? <?php require_once('includes/top.php'); //first line includes a call to session_start(); require_once('includes/db.php'); $type = filter_input(INPUT_GET, 't', FILTER_VALIDATE_INT); $order = filter_input(INPUT_GET, 'o', FILTER_VALIDATE_INT); $style = filter_input(INPUT_GET, 's', FILTER_VALIDATE_INT); /* According to documentation, filter_input returns a NULL when variables are undefined. So, if t, o, or s are not set via URL, $type, $order and $style will be NULL. */ print_r($_SESSION); /* All other sessions, such as the login session, etc. are displayed here. After the sessions are set below, they are displayed up here to... simply with no value. This leads me to believe the problem is with the code below, perhaps? */ // If $type is not null (meaning it WAS set via the get method above) // or it's false because the validation failed for some reason, // then set the session to the $type. I removed the false check for simplicity. // This code is being successfully executed, and the data is being stored... if(!is_null($type)) { $_SESSION['type'] = $type; } if(!is_null($order)) { $_SESSION['order'] = $order; } if(!is_null($style)) { $_SESSION['style'] = $style; } $smarty->display($template); ?> If anyone can point me in the right direction, I'd greatly appreciate it.

  • Achieving C# "readonly" behavior in C++

    - by Tommy Fisk
    Hi guys, this is my first question on stack overflow, so be gentle. Let me first explain the exact behavior I would like to see. If you are familiar with C# then you know that declaring a variable as "readonly" allows a programmer to assign some value to that variable exactly once. Further attempts to modify the variable will result in an error. What I am after: I want to make sure that any and all single-ton classes I define can be predictably instantiated exactly once in my program (more details at the bottom). My approach to realizing my goal is to use extern to declare a global reference to the single-ton (which I will later instantiate at a time I choose. What I have sort of looks like this, namespace Global { extern Singleton& mainInstance; // not defined yet, but it will be later! } int main() { // now that the program has started, go ahead and create the singleton object Singleton& Global::mainInstance = Singleton::GetInstance(); // invalid use of qualified name Global::mainInstance = Singleton::GetInstance(); // doesn't work either :( } class Singleton { /* Some details ommited */ public: Singleton& GetInstance() { static Singleton instance; // exists once for the whole program return instance; } } However this does not really work, and I don't know where to go from here. Some details about what I'm up against: I'm concerned about threading as I am working on code that will deal with game logic while communicating with several third-party processes and other processes I will create. Eventually I would have to implement some kind of synchronization so multiple threads could access the information in the Singleton class without worry. Because I don't know what kinds of optimizations I might like to do, or exactly what threading entails (never done a real project using it), I was thinking that being able to predictably control when Singletons were instantiated would be a Good Thing. Imagine if Process A creates Process B, where B contains several Singletons distributed against multiple files and/or libraries. It could be a real nightmare if I can not reliably ensure the order these singleton objects are instantiated (because they could depend on each other, and calling methods on a NULL object is generally a Bad Thing). If I were in C# I would just use the readonly keyword, but is there any way I can implement this (compiler supported) behavior in C++? Is this even a good idea? Thanks for any feedback.

  • How to set Minimum and Maximum Character limitation to EditText in Android?

    - by nishitpatel
    I am new to android here i have very silly problem i want to set my Edit text box minimum and maximum input value. Here I am creating one Simple validation for Edit text it only take A-Z and 0-9 value with minimum 5 and Maximum 8 character. I set the Maximum and other validation as follow. <EditText android:id="@+id/edittextKode_Listing" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginRight="5dp" android:layout_marginLeft="5dp" android:layout_alignTop="@+id/textKode_listing" android:layout_toRightOf="@+id/textKode_listing" android:maxLength="8" android:inputType="textCapCharacters" android:digits="0,1,2,3,4,5,6,7,8,9,ABCDEFGHIJKLMNOPQRSTVUWXYZ" /> but not able to set Minimum requirement. My Edit text is in alert dialog and i also apply the following code to solve this problem ` private void openInboxDialog() { LayoutInflater inflater = this.getLayoutInflater(); // declare dialog view final View dialogView = inflater.inflate(R.layout.kirim_layout, null); final EditText edittextKode = (EditText) dialogView.findViewById(R.id.edittextKode_Listing); final EditText edittextalamat = (EditText) dialogView.findViewById(R.id.edittextAlamat); edittextKode.setOnFocusChangeListener(new OnFocusChangeListener() { @Override public void onFocusChange(View v, boolean hasFocus) { // TODO Auto-generated method stub if(edittextKode.getText().toString().length() > 0){ if(edittextKode.getText().toString().length() < 5) { edittextKode.setError("Error"); Toast.makeText(GPSActivity.this, "Kode listing value not be less than 5", Toast.LENGTH_SHORT).show(); edittextKode.requestFocus(); } } } }); final AlertDialog.Builder builder = new AlertDialog.Builder(GPSActivity.this); builder.setTitle("Kirim").setView(dialogView) .setNeutralButton("OK", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // TODO Auto-generated method stub gpsCoordinates = (TextView) findViewById(R.id.text_GPS_Coordinates); kode = edittextKode.getText().toString(); alamat = edittextalamat.getText().toString(); catatan = edittextcatatan.getText().toString(); pengirim = edittextPengirim.getText().toString(); if (kode.length() > 0 && alamat.length() > 0 && catatan.length() > 0 && pengirim.length() > 0) { message = "Kode listing : " + kode + "\nAlamat : " + alamat + " \nCatatan : " + catatan + " \n Pengirim : " + pengirim + "\nKoordinat GPS : " + gpsCoordinates.getText().toString(); sendByGmail(); } else { Toast.makeText( getApplicationContext(), "Please fill all three fields to send mail", Toast.LENGTH_LONG).show(); } } }); builder.create(); builder.show(); }` in this alert dialog i have two edittext i want to apply my validation on first edittext i called the setOnFocusChangeListener to check its minimum length on focus change and if length is less than 5 request for focus but it still type in second edittext. please help me out.

  • Mutable objects and hashCode

    Have the following class: public class Member { private int x; private long y; private double d; public Member(int x, long y, double d) { this.x = x; this.y = y; this.d = d; } @Override public int hashCode() { final int prime = 31; int result = 1; result = prime * result + x; result = (int) (prime * result + y); result = (int) (prime * result + Double.doubleToLongBits(d)); return result; } @Override public boolean equals(Object obj) { if (this == obj) { return true; } if (obj instanceof Member) { Member other = (Member) obj; return other.x == x && other.y == y && Double.compare(d, other.d) == 0; } return false; } public static void main(String[] args) { Set<Member> test = new HashSet<Member>(); Member b = new Member(1, 2, 3); test.add(b); System.out.println(b.hashCode()); b.x = 0; System.out.println(b.hashCode()); Member first = test.iterator().next(); System.out.println(test.contains(first)); System.out.println(b.equals(first)); System.out.println(test.add(first)); } } It produces the following results: 30814 29853 false true true Because the hashCode depends of the state of the object it can no longer by retrieved properly, so the check for containment fails. The HashSet in no longer working properly. A solution would be to make Member immutable, but is that the only solution? Should all classes added to HashSets be immutable? Is there any other way to handle the situation? Regards.

  • What is the most idiomatic way to emulating Perl's Test::More::done_testing?

    - by DVK
    I have to build unit tests for in environment with a very old version of Test::More (perl5.8 with $Test::More::VERSION being '0.80') which predates the addition of done_testing(). Upgrading to newer Test::More is out of the question for practical reasons. And I am trying to avoid using no_tests - it's generally a bad idea not catching when your unit test exits prematurely - say due to some logic not executing when you expected it to. What is the most idiomatic way of running a configurable amount of tests, assuming no no_tests or done_testing() is used? Details: My unit tests usually take the form of: use Test::More; my @test_set = ( [ "Test #1", $param1, $param2, ... ] ,[ "Test #1", $param1, $param2, ... ] # ,... ); foreach my $test (@test_set) { run_test($test); } sub run_test { # $expected_tests += count_tests($test); ok(test1($test)) || diag("Test1 failed"); # ... } The standard approach of use Test::More tests => 23; or BEGIN {plan tests => 23} does not work since both are obviously executed before @tests is known. My current approach involves making @tests global and defining it in the BEGIN {} block as follows: use Test::More; BEGIN { our @test_set = (); # Same set of tests as above my $expected_tests = 0; foreach my $test (@tests) { my $expected_tests += count_tests($test); } plan tests = $expected_tests; } our @test_set; # Must do!!! Since first "our" was in BEGIN's scope :( foreach my $test (@test_set) { run_test($test); } # Same sub run_test {} # Same I feel this can be done more idiomatically but not certain how to improve. Chief among the smells is the duplicate our @test_test declarations - in BEGIN{} and after it. Another approach is to emulate done_testing() by calling Test::More->builder->plan(tests=>$total_tests_calculated). I'm not sure if it's any better idiomatically-wise.
