  • Across process marhalling problem with an array of points

    - by ElMagn
    Hi All, We have what we think is a marshalling problem with a renderer object when called across process boundaries. The renderer is an ATL COM server with a COM object that implements the IPoints interface defined below: typedef [uuid(B0E01719-005A-427c-B9DD-B42A18E969AE)] struct Point { double X; double Y; } Point; [ object, uuid(3BFECFE3-B4FB-4f14-8257-6E065D02E3B3), helpstring("IPoints Interface"), dual, ] interface IPoints : IDispatch { HRESULT DrawPolyLine([in] long hDC, [in] short count, [in, size_is(count)] Point * points ); // many more like DrawLine } The count parameter represents the number of points and the points parameter represents an array of the actual points. We have two process running, a graphical display process (GDP) and a tabular (grid) display process (TDP). A factory in the GDP, written in C#, creates the renderer and the clients of the renderer in the GDP. When the clients call into the renderer, everything displays correctly. The renderer is created at start up BTW. There is another factory in the TDP, written in VB6, that calls into the factory in the GDP to create the clients. When the clients call into the renderer, only the first point in the array is marshaled correctly, all the other points are garbage. Seems that the rendering works only when the client creation is started from the same process as the renderer. Now, i am not sure what the solution to this problem is. It seems that if we can guarantee that the clients are always created from a thread in the same GDP process as the renderer then the points are marshaled correctly. We tried using a background thread from the Thread Pool in C# and it indeed worked. The problem is that Windows Forms created from the clients stopped working because accessing the form's controls from a thread other than the thread that created the control is not allowed. We might change the calls to access the forms but we have quite a few of them and are trying to look into a different solution that might involve making changes to the renderer. The other problem is that the renderer is legacy code and we can't just change the interface. I am wondering what can we do to the renderer's interface that would help with marshalling from across process calls. Any ideas would be greatly appreciated. Regards, ElMagn

  • Copying Data between table without identity column

    - by user668479
    I have two table and I need to copy the data across from SRCServiceUsers to Clients Everytime i run it I get the following: Violation of PRIMARY KEY constraint 'PK_Clients'. Cannot insert duplicate key in object 'dbo.Clients'. The statement has been terminated. The Primary key ClientId field is not an identity column and therefore requires filling To date I have the following insert into Clients( ClientID, Title, Forenames, FamilyName, [Address], Town, County, PostCode, PhoneNumber, StartDate) SELECT ( Select Max(Clients.ClientID)+ 1, SRCServiceUsers.Title, SRCServiceUsers.[First Names], SRCServiceUsers.Surname, --BUILD UP MUITIPLE COLUMNS SRCServiceUsers.[Property Name] + ', ' + SRCServiceUsers.Street + ', ' + SRCServiceUsers.Suburb as [Address], SRCServiceUsers.Town, SRCServiceUsers.County, SRCServiceUsers.Postcode, SRCServiceUsers.Telephone, SRCServiceUsers.[Start Date] From srcsERVICEuSERS How can i autoincrement the PK field - CLientID when inserting the data? Many thanks Andrew

  • Is it possible / recommendable sending HTML emails containing Javascript?

    - by Adriano Varoli Piazza
    This is mostly a rhetorical question, as far as I've checked the answer is 'don't even bother', but I wanted to be really sure. We have an email app, where you can send email to lists of subscribers. This is not spam: it's used, for example, by an university to send communications to its students, by a museum to send emails to subscribers, etc. Recently, I was asked by a prospective client if it was possible to send html messages containing javascript without being marked as spam. Not knowing, I did a short trip of the webs and what I've got is (percentages out of my posterior) 'half the clients won't display properly', 'half the clients will flag you as spam' and 'half the clients will have blocked javascript altogether' (There's clearly some superposition). So the best solution seems to be adding a link to a proper page if really necessary. Have you got a different experience? Do you know of any email-merge solution that provides this feature? Do you know if specific clients accept it or refuse to display html with javascript?

  • Simple network gaming, client-server architecture planning.

    - by michal
    Hi, I'm coding simple game which I plan to make multiplayer (over the network) as my university project. I'm considering two scenarios for client-server communication: The physics (they're trivial! I should call it "collision tests" in fact :) ) are processed on server machine only. Therefore the communication looks like Client1->Server: Pressed "UP" Server->Clients: here you go, Client1 position is now [X,Y] Client2->Server: Pressed "fire" Server->Clients: Client1 hit Client2, make Client2 disappear! server receives the event and broadcasts it to all the other clients. Client1->Server: Pressed "UP" Server->Clients: Client1 pressed "UP", recalculate his position!! [Client1 receives this one as well!] Which one is better? Or maybe none of them? :)

  • Website access per client and each client having multiple users Sample Application

    - by windson
    I'm interested in building a web application in .NET that is scalable to multiple Clients and each and every Client has users associated with them. Suppose that my website is xyz.com and I have 3 clients "abc", "klm", "pqr" and I want to give access to features of xyz.com under the link as follows www.xyz.com/abc www.xyz.com/klm www.xyz.com/pqr and Client abc has N users and I want to set 3 roles for every client's user role. Is there any sample application in .NET that support this kind of website access per client having multiple users? And If I use ASP.NET Membership will that be a suitable membership solution or Do I need to opt for any other type of Membership defined by my own or already available in open source market for .NET. Edit: All the clients will have same functionality. I would like to build a generic model for www.xyz.com/{whatever} so that in future if a new client want to register with me he/she just have to give client name and up on adding client name all the features avaiable to exising clients will be applicable.

  • How Much Does Source Code Cost? Range?

    - by Brain Freeze
    I have taken a job selling a customized "online workplace management application." Our clients' businesses work around the application. Our clients track their time (which is how they get paid), finances and work documents through the application we provide and give their clients access to their interests throught the application. Our clients range from 2 users to 500 users. Each user probably processes 200 files per year and generates a fee for each file in the range of $500-$2500 per file. The application has been refined over a period of years and has cost around a million to develop. Does anyone know what range something like this sells for (source code, add-ons such as support and hosting)? I am trying to wrap my head around it as my background is not in software development.

  • RMI client tracking

    - by 0000
    I'm building a Client / Server app that has some very specific needs. There are 2 kinds of servers: the first kind provide most of the remote procedures and clients connect to these directly, while the second kind is a single server that should keep track of what users are active (clients) and how many servers of the first kind are active when a method is called. The main thing is that the monitor should ONLY connect to the servers and not the clients directly. My first idea was to implement a simple login/logout rmi method when a client connects/ disconnects and keep track of those in a list but the main problem is when a client or server end abnormally. For example, if a client goes offline abruptly the server should somehow be notified and update the list accordingly, while if a server goes out all of the clients connected to it should be marked as not active in the control server. Any ideas of how to implement this functionality would be appreciated.

  • Are there any frameworks for data subscription and update?

    - by Timothy Pratley
    There is one server with multiple clients. The clients are viewing subsets of the servers entire data. If the data that a client is viewing changes, the client should be informed of the changes so that it displays the current data. Example: Two clients are viewing a list of users in an administration screen. One client adds a new user to the list and modifies the permissions of another user. The other client sees the changes propagated to their view.

  • Java - understanding servlets

    - by Trup
    I am working on a homework project that should implement a board game between 2 clients over an HttpServlet. I have couple of questions: 1) I read that HttpServlets must be stateless, however, for the sake of the game, I have to keep a lot of state(whose turn it is, the state of the board, etc). Do I have to keep this in the clients? Does the HttpServlet indeed have to be stateless, i.e. have no fields that track state? 2) I know that the clients will talk to the servlet via the doGet/doPost methods, but how can the servlet talk to the clients(for example, if player 1 just made a move and sent it to the servlet, the servlet has to tell client 2 what the move was). Thank you Also, if you can point me to a useful, simple example of a similar code online, I would be very grateful

  • Filter a List via Another

    - by user1166905
    I have a requirement to filter a list of Clients based on if they haven't had any jobs booked in the last x months. In my code I have two lists, one is my Clients and the other is a filtered List of Jobs between today and x months ago and the idea is to filter Clients based on their id not appearing in the jobs list. I tried the following: filteredClients.Where(n => jobsToSearch.Count(j => j.Client == n.ClientID) == 0).ToList(); But I seem to get ALL clients regardless. I can easily do a foreach but this severly slows down the process. How can I filter the client list based on the job list effectively?

  • Backbone: rendering syntax

    - by ksol
    We're using Backbone.js in one of my team's projects, and this is the first time I use it. I've seen many times this kind of code (it's coffeescript, but clear enough I think. @ means this.) clients_view = new Homespa.Views.Orders.Clients.SectionView(collection: @options.clients) @$("#clients-section").html(clients_view.render().el) clients_search_view = new Homespa.Views.Orders.Clients.SearchView @$("#clients_search_modal").html(clients_search_view.render().el) Isn't there a better way to do this? I would expect to just call render on my view, and then everything's good, I shouldn't have to get the html and append/replace it by hand. Thanks for you time !

  • Why is a DataViewManager not sorting?

    - by Alarion
    First off, a quick rundown of what the code is doing. I have two tables: Companies and Clients. There is a one to many relationship between Companies and Clients (one company can have many clients). In some processing logic, I have both tables loaded into a DataSet - each are DataTables. I have added a DataRelation to set the relationship, and it works when I use GetChildRows on a record from the Companies table. However, I need to sort the records returned. After googling around some it looks like the DataViewManager is the way to go, and I have examined several basic examples. However, I cannot get my rows sorted. Am I missing something, or am I not using this how it is supposed to be used? Example code: Dim ldvmManager As New DataViewManager(mdsData) ldvmManager.DataViewSettings("Companies").Sort = "comName ASC" ldvmManager.DataViewSettings("Clients").ApplyDefaultSort = False ldvmManager.DataViewSettings("Clients").Sort = "entLastName ASC, entFirstName ASC" For Each mdrCurrentCompany in ldvmManager.DataViewSettings("Companies").Table.Rows Dim ldrClients() as DataRow = mdrCurrentCompany.GetChildRows("CompaniesClients") Next No matter what I do, the first Client returned has a last name that starts with a 'B' and the second has one that starts with a 'A'. From there, the order is all mixed up. If I use my entire data instead of the subset I was using to test with, the first Client returned has a last name that starts with 'J'. It seems like it is still using whatever default sort was being used before I tried to use the DataViewManager. Any ideas?

  • Choosing approach for an IM client-server app

    - by John
    Update: totally re-wrote this to be more succint. I'm looking at a new application, one part of which will be very similar to standard IM clients, i.e text chat, ability to send attachments, maybe some real-time interaction like a multi-user whiteboard. It will be client-server, i.e all traffic goes through my central server. That means if I want to support cross-communication with other IM systems, I am still free to pick any protocol for my own client<--server communication - my server can use XMPP or whatever to talk to other systems. Clients are expected to include desktop apps, but probably also browser-based as well either through Flex/Silverlight or HTML/AJAX. I see 3 options for my own client-server communication layer: XMPP. The benefits are clients already exist as do open-source servers. However it requires the most up-front research/learning and also appears like it might raise legal issues due to GPL. Custom sockets. A server app makes connections with the clients, allowing any text/binary data to be sent very fast. However this approach requires building said server from scratch, and also makes a JS client tricky Servlets (or similar web server). Using tried and tested Java web-stack, clients send HTTP requests similar to AJAX-based websites. The benefit is the server is easy to write using well-established technologies, and easy to talk to. But what restrictions would this bring? Is it appropriate technology for real-time communication? Advice and suggests are welcome, especially what pros and cons surround using a web-server approach as compared to a socket-based approach.

  • beginner Linq syntax and EF4 question

    - by user564577
    Question With the following linq code snip I get a list of clients with address filtered by the specifications but the form of the entities returned is not what i had expected. The data is 1 client with 2 addresses and 1 client with 1 address. The query returns 3 rows of clients each with 1 address Client 1 = Address1 Client 1 = Address2 Client 2 = Address3 var query = from t1 in context.Clients.Where(specification.SatisfiedBy()).Include("ClientAddresses") join t2 in context.ClientAddresses.Where(spec.SatisfiedBy()) on t1.ClientKey equals t2.ClientKey select t1; My expectation was a little more like a list with only two clients in it, one client with a collection of two addresses and one client with a collection of one address. Client 1 = Address1 / Address2 Client 2 = Address3 What am I missing??? Thanks!

  • How to connect to local database via website?

    - by Carlo
    Hi I have a website used by clients for reporting purposes and would like to give clients the option of my website reading their local database directly (instead of them providing data in a file format). In most instances their database would be SQL Express setup on their localhost. How can I connect to a clients local SQL server via my website, using asp.net / javascript etc? If the client provides their connection string properties, localhost would just refer to my server's localhost... Thanks

  • How to increase thread-pool threads on IIS 7.0

    - by Xaqron
    Environment: Windows Server 2008 Enterprise, IIS 7.0, ASP.NET 2.0 (CLR), .NET 4.0 I have an ASP.NET application with no page and no session(HttpHandler). It a streaming server. I use two threads for processing each request so if there are 100 connected clients, then 200 threads are used. This is a dedicated server and there's no more application on the server. The problem is after 200 clients are connected (under stress testing) application refuses new clients, but if I increase the worker threads of application pool (create a web garden) then I can have 200 new happy clients per w3wp process. I feel .NET thread pool limit reaches at that point and need to increase it. Thanks

  • What is the evidence that an API has exceeded its orthogonality in the context of types?

    - by hawkeye
    Wikipedia defines software orthogonality as: orthogonality in a programming language means that a relatively small set of primitive constructs can be combined in a relatively small number of ways to build the control and data structures of the language. The term is most-frequently used regarding assembly instruction sets, as orthogonal instruction set. Jason Coffin has defined software orthogonality as Highly cohesive components that are loosely coupled to each other produce an orthogonal system. C.Ross has defined software orthogonality as: the property that means "Changing A does not change B". An example of an orthogonal system would be a radio, where changing the station does not change the volume and vice-versa. Now there is a hypothesis published in the the ACM Queue by Tim Bray - that some have called the Bánffy Bray Type System Criteria - which he summarises as: Static typings attractiveness is a direct function (and dynamic typings an inverse function) of API surface size. Dynamic typings attractiveness is a direct function (and static typings an inverse function) of unit testing workability. Now Stuart Halloway has reformulated Banfy Bray as: the more your APIs exceed orthogonality, the better you will like static typing My question is: What is the evidence that an API has exceeded its orthogonality in the context of types? Clarification Tim Bray introduces the idea of orthogonality and APIs. Where you have one API and it is mainly dealing with Strings (ie a web server serving requests and responses), then a uni-typed language (python, ruby) is 'aligned' to that API - because the the type system of these languages isn't sophisticated, but it doesn't matter since you're dealing with Strings anyway. He then moves on to Android programming, which has a whole bunch of sensor APIs, which are all 'different' to the web server API that he was working on previously. Because you're not just dealing with Strings, but with different types, the API is non-orthogonal. Tim's point is that there is a empirical relationship between your 'liking' of types and the API you're programming against. (ie a subjective point is actually objective depending on your context).

  • serving mp3s to mobile devices is flooding nginx with partial requests

    - by drumfire
    I am serving mp3s with a minimalistic nginx server. What I see in my log files is that there are a lot of requests, in particular from AppleCoreMedia and sometimes Android useragents, that flood the server with short requests. Sometimes they keep requesting to download the same partial content for a very long time; sometimes more than an hour. For example: "GET /somefile.mp3 HTTP/1.1" 206 33041 "AppleCoreMedia/1.0.0.9B206 (iPhone; U; CPU OS 5_1_1 like Mac OS X; en_us)" "GET /somefile.mp3 HTTP/1.1" 206 33041 "AppleCoreMedia/1.0.0.9B206 (iPhone; U; CPU OS 5_1_1 like Mac OS X; en_us)" "GET /somefile.mp3 HTTP/1.1" 206 33041 "AppleCoreMedia/1.0.0.9B206 (iPhone; U; CPU OS 5_1_1 like Mac OS X; en_us)" [...] I also get a lot, but not as much, of these: "-" 400 0 "-" "-" 400 0 "-" The IP addresses are always from clients that start downloading shortly after that request, usually they have roughly the same UserAgent as in the first example. emphasized text I have enabled server throttling and connection limits in nginx to limit the huge amount of log entries from equivalent IPs at least somewhat. There was a performance issue when I saw the same behaviour on the previous server that used Apache. I installed nginx on a better server then moved the site. When Apache could not handle more connections from the increasing number of clients effectively that server was ddossed. There was no bandwidth issue with already connected clients and I don't know if the already connected clients were using more than one connection at a time. Please tell me: Are clients that appear to get stuck on a download a Bad Thing™ I heard people say their mobile bandwidth use was much higher than they could account for. I'm thinking this type of client behaviour can account for that. And costs us more bandwidth too. Which up to date alternatives exist out there that can handle serving this type of data better than plain HTTP? Useful general insights for someone who just came into this field straight out of the late 90s. :-)
