Basically we have a web service that the client uses to get all sorts of information, works well. Now I would like the client to call our web service, and for us to update our database based on the information getting passed (just a bool, and time).This will be used to determine what stage the client is at (they do QA). Is this possible?

I put a break point inside MyWebMethod. When I invoke this call on the page, the break point never gets hit. It works fine when I remove all parameters from MyWebMethod's signature and pass in '{}' from JS as parameters. Once I try to pass in a string parameter, it stops working.
Data can be fetched into an application through web service can it be possible to update data in web service from our application ..
View 2 RepliesI am creating a web app with sql server 05 and visual studio express 08. There is always live data inserted into my sql tables throughout the day infrequently.
I want to create a web page that will show the data in graphs etc. I can currently show the data present in the database on the web page. HOWEVER what i do not know is how to update the page (graphs) with the NEW DATA that has been inserted into the tables.
I guess I will have to use ajax to change the data shown on the web page automatically. I will also need somesort of triggers to tell when new data has arrived.
I have a webservice - called MyCompany.WebService1
I reference this using a web reference in my ASP.net web application.
Theres a method called "GetDeal" in this web service, that returns a "Deal" Object.
The deal object currently looks (for example) like this:
[code]....
This class is in a different assembly: MyCompany.Model
The web service references this assembly.
In my web app, I can call the GetDeal method. This returns Service1.Deal (service1 is just the name of the web reference)
I can access both properties above. I have now changed the Deal class, and added a couple more properties.
However, I can't see these new properties in my web application. I've updated the web service in the web application. I rebuilt the web service several times, tried removing the MyCompany.Model reference and re-addding it etc...
I can't figure out what has changed... This was working - I have changed the model before, and it's updated the reference correctly...
I am trying to update client side controls asynchronously with information from a service.
The service I am using has a callback delegate that points to the users web page (server side)
I would like to update information on the page that is initiated by another users also consuming the same service. exactly like a chatroom.
I am trying to use an update panel, and call updatepanel.update() (server side) once I recieve the information from the service. basically: how do I partially update control data from the server side so that client side can see it.
I've been given the task of consuming a client's web service, and all they've given me is a XSD file. I'm a little unsure how to go about doing this, as the only other time I've consumed a web service was internally and we just pulled it in as a web reference to our project. Where do I start when all I have the XSD (below)?
<?xml version="1.0" encoding="UTF-8"?>
here's my issue. I'm trying to run service based applications from Visual Studio. My previous workstation died, and I got a replacement, and I can no longer run the service based apps from Visual Studio, so obviously there's something that I neglected to reload. The specific error I'm getting is:
Cannot start service from the command line or a debugger. A Windows Service must first be intstalled ( using installutil.exe) and then started with the ServerExplorer, Windows Services Administrative tool, or the NET START command.Going through debugger, I eventually get the error "Service <appname> was not found on computer .."The DOS environment does not seem recognize the installutil.exe command.

View 1 RepliesI'm trying to insert a new EF object containing a reference to a related table via foreign key, and cannot get the reference stored in the new object. I have two tables in a SQL Server 2008 Database:
Component Templates
PartGroups
with a Foreign Key linking them thus: ComponentTemplates:ID [0..1<->*] PartGroups:ComponentTemplateID
I have imported these tables into a .NET web application project .edmx file (using a new ADO.NET Entity Data Model), and then created a Data Service which I then reference in a Silverlight 3.0 project. The objects are available as expected in the data context called by my Silverlight app and load correctly. Now, when I try to save a reference of ComponentTemplate into a newly created PartGroup, the PartGroup object is created in the database, but the value of ComponentTemplateID in the newly created table record is NULL.
[Code]....
(Note that _ctCtrl.ComponentTemplate is a confirmed non-NULL object reference to the parent object on which PartGroup is a child)
We have an existing, proprietary data processing application that runs on one of our servers and we wish to expose it as a web service for our clients to submit jobs remotely. In essence, the system takes a set of configuration parameters and one or more data files (the number of files depends on the particular configuration template, but the normal config is 2 files). The application then takes the input files, processes them, and outputs a single result data file (all files are delimited text / CSV or tab).
We want to now expose this process as a service. Based on our current setup and existing platforms, we are fairly confident that we want to go with WCF 4.0 as the framework and likely REST for the service format, though a SOAP implementation may be required at some point.
Although I am doing a lot of reading on SOA, WCF and REST, I am interested in other thoughts on how to model this service. In particular, the one-to-many relationship of job to required files for input. It seems pretty trivial to model a "job" in REST with the standard CRUD commands. However, the predefined "job type" parameter defines the number of files that must be included. A job type of "A" might call for two input files, while "B" requires 3 before the job can run.
Given that, what is best way to model the job? Do I include the multiple files in the initial creation of the job? Do I create a job and then have an "addFile" method where by I can then upload the necessary number of files?
The jobs will then have to run asynchronously because they can take time. Once complete, is it best to then just have a status field in the job object and require the client to regularly query the system for job status, or perhaps have the client provide a URL to "ping" when the job is complete?
We are designing a system that has functionality that is essentially the same at the presentation layer and the exposed API layer. My question is what technique / strategy to use so we can get the most reuse out of our code with performance in mind? Here's a simplified example: A user can add a Customer via a web form. This will fire the Customer.Create() method. An API consumer / user can add a Customer via a SOAP / HTTP-POST to a web service which will call the Customer.Create() method.
Imagine these layers:
PRESENTATION
|
|
WEB SERVICE API (Customer.Create() is available here
|
|
FACADE Business Object Interface - Customer.Create() signature is here
|
|
BUSINESS Business object - Customer.Create method() is fleshed out here
|
|
DATA ACCESS - Writes data
The presentation layer SOAP calls the Create() web method, which calls the facade's Create() method which calls the business object's Create() method which wires via the data access layer.
Questions:
Is there a concern about performance in using the API's web services in our presentation layer, or are there alternatives to connect the presentation layer directly to the facade? If so, what technology to use (WCF, Remoting, Web Services, etc)?

View 1 RepliesI have built a WCF Service that is being consumed by a Silverlight app. At first I created one method that was very simple:
public String SfTest()
{
return "SF Test";
}
No poblem. My silverlight app references my service and displays "SF Test" in a textbox. Now I add a method to my wcf service like this:
public List<String> GetTest()
{
List<String> list = new List<string>();
String a = "a";
list.Add(a);
String b = "b";
list.Add(b);
return list;
}
I update the reference to the service in my Silverlight app and the using statement in my xaml cs page throws an error like the service doesn't even exist although it is there. I am assuming the problem has to do with datatypes or serialization or something like that but it is driving me up the wall. Why can't I consume a simple generic list in my Silverlight app through the WCF service.
I developed a web service in VS2010 on my local machine, wrote a consumer of it also locally, and that all works.
I copied the dll and the asmx file to our server, and I am getting an error when I try to invoke it from a browser (also still on the server machine) to make sure it correctly exposes its web methods, but it is not, it is saying "Could not create type 'Service'". That error comes from this line:
Line 1: <%@ WebService Language="C#" CodeBehind="~/App_Code/WarrantyDuplicate.cs" Class="Service" %>
There other web services in the same folder on the server that all work fine so I don't believe it's an IIS setup thing.
This is my first web service in C# and when I created it in VS I did think it odd that the code behind file went into App_Code (as you can see from the line in the asmx file) and is just named dot-cs rather than asmx-dot-cs. But since it worked fine locally, I wasn't sure that mattered.
I have asp.net 2.0 site which is calling web services hosted on another server. When i have an xml file from where web service ip for eg. www.mysite/webservice1/myservice.asmx is given. When i call the same server from developer machine using local networkit works fine.But the same is when hosted remotely and from client end when services is called reading xml fiile from client machine it given a message 'remote server not connecting'.
View 1 RepliesI am not sure which approach I should use. I have a web application that needs to get/receive data from a third party application that is in a secure remote network. The data needs to be secure during transport. The data layers cannot be exposed and the databases will not talk to each other. The data will be received from remote application on demand, or will get at scheduled intervals.
I have looked at WCF, but not sure if this will work. Can a WCF service be used to receive data as needed from a remote sender or service? Is this a secure way of doing it? I have also looked at SFTP using some XML/XSLT, but I don't think this is the right way to go. In addition, some data may be transported from my web application to the remote application (mostly reports at first). What protocols are used to transfer data between HIPAA compliant applications?
I am writing two ASP.NET apps. One is a web service that provides xml data and the other is a web client that will use the service to display and manipulate data. I would like for the web service to do the membership authentication and authorization. Is there any way to simply point the login controls in my client application to the web service instead of to a database. I assume I would have to provide the necesarry methods in my web service interface, which would then use the membership provider database I created and pass the results back through to the client.
Is this possible? I have seen many articles on security provisioin from a web service but none has really been what I am looking for. I was hoping that, since my service and my client are both written in ASP.NET, there might be some built functionality that would benefit me.
I'm currently trying to work out the best way to build this web application, which will then be intergrated on other systems, such as WinForms, Intranets etc.
We hope to include the usual layers i.e. DAL, BLL, BOL and UI but I have been experimenting with Entity Framework 4 and WCF Data Services and managed to get something in place where I was using WCF as a gateway to EF4.
i.e. Adding a Service Reference to my project and then using the EF4 context and writing LINQ queries against the DB
e.g.[Code]....
Now with the current setup I would still need to write a DAL Class Library, that interacts with the Data Service, because as I said WCF Data Services only seems to be a gateway, I can't see where to put the code (above) in the Data Service and then how I could these methods.
My questions are: 1. How do I develop a WCF Data Service in such a way to allow this behaviour - I know how I could do it using ASMX web service, something like [Code]....
2. If I am to use WCF Data Services, how is serialization handled (if at all) - again I know how to do something in ASMX web services
3. Again, If I am to use WCF, how do I add Security and only allow my applications to access the web service - for obvious reasons
4. Would it be possible / logical to also include the Business Logic Layer into the web service?
Is it possible to run a web service as a particular user/service account in the same way a Windows service can?I have a service account used for connecting to the DB and want to run the webservice under this account as the users using the webservice won't have DB access.The way I see to do it is to include the Impersonate option in the Web.config file, but is there any better way to do this?
