• Reasonable technological solutions to create CRM using .NET eventually Java

  - by user1825608

  My background(If it's too long, just skip it please ; ) ): I am Java programmer(because of demand): mostly teacher for other students, worked on few thesis for others, but during my journey I discovered that .NET and Microsoft's tools are on at least two levels higher than Java and its tools so I want to learn more about them. I programmed little bit on Windows Phone(NFC Tags, TCP Clients, guitar tuner using internal microphone, simple RSS), used WPF, integrated WPF with Windows Forms, Apple Bonjour(.NET), I have expierience with IP cameras and with unusal problems, I learn Android, but I don't like it at all. Problem: I was asked by my friend to create CRM for small new company. There will maximum 20 workers in the company working at computers in few cities in the country(Poland). They just want to store contracts with the clients and client's data. I am not sure what exacly they do but probably sell apartments so there will be at most few thousands of contracts to store in far future. Now I am totally new to CRM but I want to learn. I have few questions: Should the data be stored on a server in the company's building running 24/7 or cloud. If cloud which one? Should I use ASPX or WPF. I read one topic about it but as far as I know aspx sites can be viewed from every device with internet browser: tablets, phones(Android, WP, iOS) and computers at the same time- so the job is done once and for all(Am I right?), I don't know nothing about aspx. Can WPF be also used in manner that does not need to port it for other platforms?

• Minimizing data sent over a webservice call on expensive connection

  - by aceinthehole

  I am working on a system that has many remote laptops all connected to the internet through cellular data connections. The application will synchronize periodically to a central database. The problem is, due to factors outside our control, the cost to move data across the cellular networks are spectacularly expensive. Currently the we are sending a compressed XML file across the wire where it is being processed and various things are done with (mainly stuffing it into a database). My first couple of thoughts were to convert that XML doc to json, just prior to transmission and convert back to XML just after receipt on the other end, and get some extra compression for free without changing much. Another thought was to test various other compression algorithms to determine the smallest one possible. Although, I am not entirely sure how much difference json vs xml would make once it is compressed. I thought that their must be resources available that address this problem from an information theory perspective. Does anyone know of any such resources or suggestions on what direction to go in. This developed on the MS .net stack on windows for reference.

• Why does DataContractJsonSerializer not include generic like JavaScriptSerializer?

  - by Patrick Magee

  So the JavaScriptSerializer was deprecated in favor of the DataContractJsonSerializer. var client = new WebClient(); var json = await client.DownloadStringTaskAsync(url); // http://example.com/api/people/1 // Deprecated, but clean looking and generally fits in nicely with // other code in my app domain that makes use of generics var serializer = new JavaScriptSerializer(); Person p = serializer.Deserialize<Person>(json); // Now have to make use of ugly typeof to get the Type when I // already know the Type at compile type. Why no Generic type T? var serializer = new DataContractJsonSerializer(typeof(Person)); Person p = serializer.ReadObject(json) as Person; The JavaScriptSerializer is nice and allows you to deserialize using a type of T generic in the function name. Understandably, it's been deprecated for good reason, with the DataContractJsonSerializer, you can decorate your Type to be deserialized with various things so it isn't so brittle like the JavaScriptSerializer, for example [DataMember(name = "personName")] public string Name { get; set; } Is there a particular reason why they decided to only allow users to pass in the Type? Type type = typeof(Person); var serializer = new DataContractJsonSerializer(type); Person p = serializer.ReadObject(json) as Person; Why not this? var serializer = new DataContractJsonSerializer(); Person p = serializer.ReadObject<Person>(json); They can still use reflection with the DataContract decorated attributes based on the T that I've specified on the .ReadObject<T>(json)

• Is this the correct way to implement .NET MVC website structure?

  - by aspdotnetuser

  I have recently seen a .NET MVC solution in which the markup in the .aspx views have a Controller as their model, and the .ascx user controls they contain use a separate model. I'm new to MVC and I wanted to find out about a few things I'm not clear on. An example of how the code is implemented: UserDetails.aspx view has markup that shows it's using the UserDetailsController.cs as the model. It contains RenderPartial("User_Details.ascx", UserDetailsModel) and passes it the UserDetailsModel. Is this the standard/correct way of implementing MVC? Or just one way to implement it? I also noticed that the classes used as Models appear to be Service classes that have [DataMember] and [DataContract] attributes on the class name and properties - what is the advantage of this implementation?

• Is passing the Model around in this way considered bad practice?

  - by Theomax

  If I have a view called, for example, ViewDetails that displays user information in labels and has a Model called ViewDetailsModel and if I want to allow the user to click a button to edit some of these details, is it considered bad practice is I pass the entire Model in the markup to a controller method which then assigns the values for another model, using the values stored in the Model that was passed in as a parameter to that action method? If so, should there instead be a service method that gets the data required for the edit view? For example: In the ViewDetails view, the user clicks the edit button which calls an action method in the controller (and passes in the Model object). The action method then uses the data in the Model object to populate another model which will be used for the EditDetails view that will be returned.

• MVC or Extract Service Layer

  - by Lizzard

  we have an application that is built with .Net MVC. We are now tasked with exposing API's to third parties. Members on our team want to just continue down our current path and just use more controllers so we can reuse the backend of our current application. Logic tells me we need to create a seperate service layer when more clients are going to be accessing it, but .Net MVC seems to take care of all of this. Is it really acceptable architecture to use controllers in a stand alone application to expose API's and what would be the potential gains of extracting the service layer out?

• Apple Push Notification-Unable to callback didRegisterForRemoteNotificationsWithDeviceToken

  - by Shailesh Kanzariya

  I have been simply trying to get deviceToken from my iPhone application using Apple Push Notification Service. I don't have any implementation on server side for the time being. I have created APP Id, got SSL certificate, Provision Profile with APN and calling - (void)applicationDidFinishLaunching:(UIApplication *)application { //view init and add sub view to window [[UIApplication sharedApplication] registerForRemoteNotificationTypes:UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound]; } method. When I execute the application it pop ups action box to allow Push Notification (means my request for APN registration is working) but my callback is not executed. Neither didRegisterForRemoteNotificationsWithDeviceToken nor didFailToRegisterForRemoteNotificationsWithError is called? can anybody help me to resolve the issue? Following are my callbacs for reference. - (void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)err { UIAlertView *myAlert = [[UIAlertView alloc] initWithTitle:@"APNClient" message:@"Entered into Error Method" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [myAlert show]; [myAlert release]; NSLog(@"Error in registration. Error: %@", err); } - (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)devToken { UIAlertView *myAlert = [[UIAlertView alloc] initWithTitle:@"APNClient" message:@"Got the deviceToken..!" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [myAlert show]; [myAlert release]; }

• Rails Associations - Callback Sequence/Magic

  - by satynos

  Taking following association declaration as an example: class Post has_many :comments end Just by declaring the has_many :comments, ActiveRecord adds several methods of which I am particularly interested in comments which returns array of comments. I browsed through the code and following seems to be the callback sequence: def has_many(association_id, options = {}, &extension) reflection = create_has_many_reflection(association_id, options, &extension) configure_dependency_for_has_many(reflection) add_association_callbacks(reflection.name, reflection.options) if options[:through] collection_accessor_methods(reflection, HasManyThroughAssociation) else collection_accessor_methods(reflection, HasManyAssociation) end end def collection_accessor_methods(reflection, association_proxy_class, writer = true) collection_reader_method(reflection, association_proxy_class) if writer define_method("#{reflection.name}=") do |new_value| # Loads proxy class instance (defined in collection_reader_method) if not already loaded association = send(reflection.name) association.replace(new_value) association end define_method("#{reflection.name.to_s.singularize}_ids=") do |new_value| ids = (new_value || []).reject { |nid| nid.blank? } send("#{reflection.name}=", reflection.class_name.constantize.find(ids)) end end end def collection_reader_method(reflection, association_proxy_class) define_method(reflection.name) do |*params| force_reload = params.first unless params.empty? association = association_instance_get(reflection.name) unless association association = association_proxy_class.new(self, reflection) association_instance_set(reflection.name, association) end association.reload if force_reload association end define_method("#{reflection.name.to_s.singularize}_ids") do if send(reflection.name).loaded? || reflection.options[:finder_sql] send(reflection.name).map(&:id) else send(reflection.name).all(:select => "#{reflection.quoted_table_name}.#{reflection.klass.primary_key}").map(&:id) end end end In this sequence of callbacks, where exactly is the actual SQL being executed for retrieving the comments when I do @post.comments ?

• Jquery animation callback issues

  - by ChrisOPeterson

  I'm trying to build a simple carousel animation with jQuery. There are 3 viewable images at any one time with buttons to click on each side to go forward or backwards. The center image is raised up by 30px to be given prominence. When one of the buttons is pushed the center image should drop down then all three images move together left or right. The initial up and down animation works but on a callback none of the other animations will work. If I hard code the direction into them only one of them works. Is there something wrong with my current code or approach? ctr_right.click(function() { carouselAnimate("right") }); ctr_left.click(function() { carouselAnimate("left") }); function carouselAnimate(direction) { var offset = img_width + img_offset; img_focus.animate({"top": "+="+focus_offset}, "slow", function() { img_left.animate({direction: "-="+offset}, "slow"); img_focus.animate({direction: "-="+offset}, "slow"); img_right.animate({direction: "-="+offset}, "slow"); }); };

• Android : Handle OAuth callback using intent-filter

  - by Dave Allison

  I am building an Android application that requires OAuth. I have all the OAuth functionality working except for handling the callback from Yahoo. I have the following in my AndroidManifest.xml : <intent-filter> <action android:name="android.intent.action.VIEW"></action> <category android:name="android.intent.category.DEFAULT"></category> <category android:name="android.intent.category.BROWSABLE"></category> <data android:host="www.test.com" android:scheme="http"></data> </intent-filter> Where www.test.com will be substituted with a domain that I own. It seems : This filter is triggered when I click on a link on a page. It is not triggered on the redirect by Yahoo, the browser opens the website at www.test.com It is not triggered when I enter the domain name directly in the browser. So can anybody help me with When exactly this intent-filter will be triggered? Any changes to the intent-filter or permissions that will widen the filter to apply to redirect requests? Any other approaches I could use? Thanks for your help.

• ASP.NET dropdownlist callback doesn't work inside div

  - by Wayne Werner

  This seems super weird to me. I have a callback handler done in VB which works fine with this code: <!-- Div Outside Form --> <div class="container"> <form id="querydata" runat="server"> <asp:DropDownList runat="server" ID="myddl" AutoPostBack="true" OnSelectedIndexChanged="myddlhandler"> <asp:ListItem>Hello</asp:ListItem> <asp:ListItem>Goodbye</asp:ListItem> </asp:DropDownList> <asp:Label runat="server" ID="label1"></asp:Label> </form> </div> <!-- Yep, they're matching --> I can change the value and everything is A-OK, but if I change the code to this (div inside form): <form id="querydata" runat="server"> <!-- Div inside form doesn't work :( --> <div class="container"> <asp:DropDownList runat="server" ID="myddl" AutoPostBack="true" OnSelectedIndexChanged="myddlhandler"> <asp:ListItem>Hello</asp:ListItem> <asp:ListItem>Goodbye</asp:ListItem> </asp:DropDownList> <asp:Label runat="server" ID="label1"></asp:Label> </div> </form> It the postback no longer works. Is how asp is supposed to work? Or is it some magic error that only works for me? And most importantly, if asp is not supposed to work this way, how should I be doing this? Thanks!

• How can a SVN::Error callback identify the context from which it was called

  - by Colin Fine

  I've written some fairly extensive Perl modules and scripts using the Perl bindings SVN::Client etc. Since the calls to SVN::Client are all deep in a module, I have overridden the default error handling. So far I have done so by setting $SVN::Error::handler = undef as described in [1], but this makes the individual calls a bit messy because you have to remember to make each call to SVN::Client in list context and test the first value for errors. I would like to switch to using an error handler I would write; but $SVN::Error::handler is global, so I can't see any way that my callback can determine where the error came from, and what object to set an error code in. I wondered if I could use a pool for this purpose: so far I have ignored pools as irrelevant to working in Perl, but if I call a SVN::Client method with a pool I have created, will any SVN::Error object be created in the same pool? Has anybody any knowledge or experience which bears on this?

• Setting objct literal property value via asynchronous callback.

  - by typeof

  I'm creating a self-contained javascript utility object that detects advanced browser features. Ideally, my object would look something like this: Support = { borderRadius : false, // values returned by functions gradient : false, // i am defining dataURI : true }; My current problem deals with some code I'm adapting from Weston Ruter's site which detects dataURI support. It attempts to use javascript to create an image with a dataURI source, and uses onload/onerror callbacks to check the width/height. Since onload is asynchronous, I lose my scope and returning true/false does not assign true/false to my object. Here is my attempt: Support = { ... dataURI : function(prop) { prop = prop; // keeps in closure for callback var data = new Image(); data.onload = data.onerror = function(){ if(this.width != 1 || this.height != 1) { that = false; } that = true; } data.src = "data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///ywAAAAAAQABAAACAUwAOw=="; return -1; }(this) }; I'm executing the anonymous function immediately, passing this (which I hoped was a reference to Support.dataURI), but unfortunately references the window object -- so the value is always -1. I can get it to work by using an externally defined function to assign the value after the Support object is created... but I don't think it's very clean that way. Is there a way for it to be self-contained? Can the object literal's function reference the property it's assigned to?

• C callback functions defined in an unnamed namespace?

  - by Johannes Schaub - litb

  Hi all. I have a C++ project that uses a C bison parser. The C parser uses a struct of function pointers to call functions that create proper AST nodes when productions are reduced by bison: typedef void Node; struct Actions { Node *(*newIntLit)(int val); Node *(*newAsgnExpr)(Node *left, Node *right); /* ... */ }; Now, in the C++ part of the project, i fill those pointers class AstNode { /* ... */ }; class IntLit : public AstNode { /* ... */ }; extern "C" { Node *newIntLit(int val) { return (Node*)new IntLit(val); } /* ... */ } Actions createActions() { Actions a; a.newIntLit = &newIntLit; /* ... */ return a; } Now the only reason i put them within extern "C" is because i want them to have C calling conventions. But optimally, i would like their names still be mangled. They are never called by-name from C code, so name mangling isn't an issue. Having them mangled will avoid name conflicts, since some actions are called like error, and the C++ callback function has ugly names like the following just to avoid name clashes with other modules. extern "C" { void uglyNameError(char const *str) { /* ... */ } /* ... */ } a.error = &uglyNameError; I wondered whether it could be possible by merely giving the function type C linkage extern "C" void fty(char const *str); namespace { fty error; /* Declared! But i can i define it with that type!? */ } Any ideas? I'm looking for Standard-C++ solutions.

• Visitor Pattern can be replaced with Callback functions?

  - by getit

  Is there any significant benefit to using either technique? In case there are variations, the Visitor Pattern I mean is this: http://en.wikipedia.org/wiki/Visitor_pattern And below is an example of using a delegate to achieve the same effect (at least I think it is the same) Say there is a collection of nested elements: Schools contain Departments which contain Students Instead of using the Visitor pattern to perform something on each collection item, why not use a simple callback (Action delegate in C#) Say something like this class Department { List Students; } class School { List Departments; VisitStudents(Action<Student> actionDelegate) { foreach(var dep in this.Departments) { foreach(var stu in dep.Students) { actionDelegate(stu); } } } } School A = new School(); ...//populate collections A.Visit((student)=> { ...Do Something with student... }); *EDIT Example with delegate accepting multiple params Say I wanted to pass both the student and department, I could modify the Action definition like so: Action class School { List Departments; VisitStudents(Action<Student, Department> actionDelegate, Action<Department> d2) { foreach(var dep in this.Departments) { d2(dep); //This performs a different process. //Using Visitor pattern would avoid having to keep adding new delegates. //This looks like the main benefit so far foreach(var stu in dep.Students) { actionDelegate(stu, dep); } } } }

• Problems with Backbone.Model callback and THIS

  - by Rev. Samuel

  I'm building a simple weather widget. The current weather conditions are read out of the National Weather Service xml file and then I want to parse and store the relevant data in the model but the callback for the $.ajax won't connect (the way I'm doing it). var Weather = Backbone.Model.extend({ initialize: function(){ _.bindAll( this, 'update', 'startLoop', 'stopLoop' ); this.startLoop(); }, startLoop: function(){ this.update(); this.interval = window.setInterval( _.bind( this.update, this ), 1000 * 60 * 60 ); }, stopLoop: function(){ this.interval = window.clearInterval( this.interval ); }, store: function( data ){ this.set({ icon : $( data ).find( 'icon_url_name' ).text() }); }, update: function(){ $.ajax({ type: 'GET', url: 'xml/KROC.xml', datatype: 'xml' }) .done( function( data ) { var that = this; that.store( $( data ).find( 'current_observation' )[ 0 ] ); }); } }); var weather = new Weather(); The data is read correctly but I can't get the done function of the call back to call the store function. (I would be happy if the "done" would just parse and then do "this.set". Thanks in advance for your help.

• Callback from static library

  - by MortenHN

  I think this should be simple, but im having a real hard time finding information about this topic. I have made a static library and have no problem getting the basics to work. But im having a hard time figuring out how to make a call back from the static library to the main APP. I would like my static library to only use one header as front, this header should contain functions like: requestImage:(NSString *)path; requestLikstOfSomething:(NSSting *)guid; and so on.. These functions should do the necessary work and start a async NSURLConnection, and call back to the main application when the call have finished. How do you guys do this, what are the best ways to callback from a static library when a async method is finished? should i do this with delegates (is this possible), notifications, key/value observers. I really want to know how you guys have solved this, and what you regard as the best practices. Im going to have 20-25 different calls so i want the static library header file to be as simple as possible preferable only with a list of the 20-25 functions. UPDATE: My question is not how to use delegate pattern, but witch way is the best to do callbacks from static librarys. I would like to use delegates but i dont want to have 20-25 protocol declarations in the public header file. I would prefer to have only one function for each request. Thanks in advance. Best regards Morten

• Coffeescript getting proper scope from callback method

  I've searched for this and can't seem to find an successful answer, I'm using a jQuerey ajax call and I can't get the response out to the callback. Here's my coffeescript code: initialize: (@blog, @posts) -> _url = @blog.url _simpleName = _url.substr 7, _url.length _avatarURL = exports.tumblrURL + _simpleName + 'avatar/128' $.ajax url: _avatarURL dataType: "jsonp" jsonp: "jsonp" (data, status) => handleData(data) handleData: (data) => console.log data @avatar = data Here's the compiled JS: Blog.prototype.initialize = function(blog, posts) { var _avatarURL, _simpleName, _url, _this = this; this.blog = blog; this.posts = posts; _url = this.blog.url; _simpleName = _url.substr(7, _url.length); _avatarURL = exports.tumblrURL + _simpleName + 'avatar/128'; return $.ajax({ url: _avatarURL, dataType: "jsonp", jsonp: "jsonp" }, function(data, status) { return handleData(data); }); }; Blog.prototype.handleData = function(data) { console.log(data); return this.avatar = data; }; I've tried a dozen variations and I can't figure out how to write this?

I want to keep it completely and utterly secure and private however we need to expose some information through a WCF service to another server which hosts our external websites which CAN be accessed by the public. What is the best way to pass information between the two servers with regards to an IT setup, while keeping the intranet in house server completely secure and inaccessible? I've heard VPN was the way to go but I wanted to be sure this was the safest way. Another question what would be the most secure way of passing data in the WCF service?

• Asynchronous callback for network in Objective-C Iphone

  - by vodkhang

  I am working with network request - response in Objective-C. There is something with asynchronous model that I don't understand. In summary, I have a view that will show my statuses from 2 social networks: Twitter and Facebook. When I clicked refresh, it will call a model manager. That model manager will call 2 service helpers to request for latest items. When 2 service helpers receive data, it will pass back to model manager and this model will add all data into a sorted array. What I don't understand here is that : when response from social networks come back, how many threads will handle the response. From my understanding about multithreading and networking (in Java), there must have 2 threads handle 2 responses and those 2 threads will execute the code to add the responses to the array. So, it can have race condition and the program can go wrong right? Is it the correct working model of iphone objective-C? Or they do it in a different way that it will never have race condition and we don't have to care about locking, synchronize? Here is my example code: ModelManager.m - (void)updateMyItems:(NSArray *)items { self.helpers = [self authenticatedHelpersForAction:NCHelperActionGetMyItems]; for (id<NCHelper> helper in self.helpers) { [helper updateMyItems:items]; // NETWORK request here } } - (void)helper:(id <NCHelper>)helper didReturnItems:(NSArray *)items { [self helperDidFinishGettingMyItems:items callback:@selector(model:didGetMyItems:)]; break; } } // some private attributes int *_currentSocialNetworkItemsCount = 0; // to count the number of items of a social network - (void)helperDidFinishGettingMyItems:(NSArray *)items { for (Item *item in items) { _currentSocialNetworkItemsCount ++; } NSLog(@"count: %d", _currentSocialNetworkItemsCount); _currentSocialNetworkItemsCount = 0; } I want to ask if there is a case that the method helperDidFinishGettingMyItems is called concurrently. That means, for example, faceboook returns 10 items, twitter returns 10 items, will the output of count will ever be larger than 10? And if there is only one single thread, how can the thread finishes parsing 1 response and jump to the other response because, IMO, thread is only executed sequently, block of code by block of code

• jquery, manipulate content inserted by ajax, without using the callback

  - by Cody

  I am using ajax to insert a series of informational blocks via a loop. The blocks each have a title, and long description in them that is hidden by default. They function like an accordion, only showing one description at a time amongst all of the blocks. The problem is opening the description on the first block. I would REALLY like to do it with javascript right after the loop that is creating them is done. Is it possible to manipulate elements created ofter an ajax call without using the callback? <!-- example code--> <style> .placeholder, .long_description{ display:none;} </style> </head><body> <script> /* yes, this script is in the body, dont know if it matters */ $(document).ready(function() { $(".placeholder").each(function(){ // Use the divs to get the blocks var blockname = $(this).html(); // the contents if the div is the ID for the ajax POST $.post("/service_app/dyn_block",'form='+blockname, function(data){ var divname = '#div_' + blockname; $(divname).after(data); $(this).setupAccrdFnctly(); //not the actual code }); }); /* THIS LINE IS THE PROBLEM LINE, is it possible to reference the code ajax inserted */ /* Display the long description in the first dyn_block */ $(".dyn_block").first().find(".long_description").addClass('active').slideDown('fast'); }); </script> <!-- These lines are generated by PHP --> <!-- It is POSSIBLE to display the dyn_blocks --> <!-- here but I would really rather not --> <div id="div_servicetype" class="placeholder">servicetype</div> <div id="div_custtype" class="placeholder">custtype</div> <div id="div_custinfo" class="placeholder">custinfo</div> <div id="div_businfo" class="placeholder">businfo</div> </body>
