Xml - Use A Custom Class To Return Data From A Web Service?
Feb 11, 2011So I have an application that uses a webservice, On the UI side the user picks a table which sends a request across the web to my webservice to return the fields of this table. So after this request is accomplished I have, on the webservice side a series of Name,Type Pairs that I need to serialize and send back to my client. I could use a List(of String()) to send the values back but I want to use a List(of Custom_Class) instead because later I have to do this on a much larger scale and I want to learn on this simpler version.

.net - .NET XML Web Service, Consuming Class Not Able To Access Web Service Class?
Mar 21, 2012I am creating a simple XML web service and have run into something I can't quite explain.My web service class has the following structure :
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.ComponentModel
[code]....
Invoking my method using the built in VS web service test harness works fine. I created another project, in another solution, to test consuming the web service. I added a web reference to my project and set it so I could reference my web service by using "localWS". Then in the page load event of my consuming class I tried to instantiate an object of my web service:
Dim srv As New localWS.MyWS
But there was no "MyWS" type found. There is however a localWS.MyWSSoapClient class. When I use it I can invoke my web methods. My question is, why can't I create a straight up version of MyWS class? In the tutorials I'v read, and in the book I have, example consuming classes for .NET XML web services can instantiate objects of the web service class they are consuming. As a further test I added a new web form to my web service project and from there I was able to instantiate a MyWS class.
Windows Service: Multiple Instances Of The Same Service Class?
May 3, 2011When you create a Windows Service, you create a list of the services you want to start. The default is this:
ServicesToRun = New System.ServiceProcess.ServiceBase() {New Service}
Can you have multiple instances of the same Service class (that bind to different addresses or ports), like this?
ServicesToRun = New System.ServiceProcess.ServiceBase() {New Service("Option1"), New Service("Option2")}
Or will that cause problems? Should we use two different classes instead?
Inside The Service Class, Declare A Class Variable Named Started?
May 8, 2012Create a class named Service. Inside the Service class, declare a class variable named Started. The datatype of this variable is Boolean.Public Class Service Dim started as Boolean End Class Create a class named Server. Inside the Server class, declare a dynamic array that can contain elements of the type Service.(Note: For convenience, both the array and the variable Started can be accessible from a client program that creates an instance of Server and Service respectively)
Create a constructor for the Service class. When the constructor is executed, it will set the value of the class variable Started to True. Create two new classes: WebServer and DatabaseEngine. Both of these classes inherit from the class Service. Inside the Service class, declare a Sub procedure (method) named Terminate. This method should display the following text Service stopping in a message box when executed.This method can be overridden in classes that inherit from Service class.
Inside both the WebServer and DatabaseEngine class, override the method Terminate inherited from their base class Service. Both methods should first call the base class Terminate method. The messages Web server stopping and Database engine stopping should also be displayed in a message box when the Terminate method for the WebServer and DatabaseEngine are called respectively. These messages should only be displayed if the Started variable inherited from their base class is not equal to False.
Inside the Server class, declare a method named Shutdown. This method does not return any value. When executed, it will call the Terminate method for each of the Service instances (if any) in the arrServices
array. You should call the Terminate method within a For Each loop that loops through the elements of the arrServices array.
In the Sub Main method, create an instance of the class Server. Set the size of the arrServices array in
your Server instance to contain 2 elements. Create first a WebServer instance and then a DatabaseEngine
instance into this array. Call the Shutdown method from your Server instance.

View 2 RepliesAdding A Windows Service Class To A Class Library
Feb 14, 2012I have a class library in VB.NET that does a NET-envelope for an USB device driver.There is only one function of that driver that I could not envelope in a traditional class, but I had to put it in a Windows Service as described here:Sharing a class property (field) between applications.The Windows Service works fine, but I have now two projects for my NET-envelope: the one with the class library, the second with the windows service and I do not like the idea to maintain two distinct projects for the same driver.Is it a good practice (or even if possible) to add a windows service class to a normal class library (without creating its own project as described in the vb tutorial)?I know, in any case I should create a separate setup only for the windows service, but in this way I could have together all the classes that envelope my usb device driver in only one project.

Public Structure In Web Service As Return Value In Function
Sep 24, 2010I have a windows app that references a web service I created. In the web service, I created a function that needed to return more than one value. Because of this, I created a public structure in the web service:
Public Structure MyRecordSet
Public lstOfDataInRecord As List(Of String)
Public iNumberOfRecords As Integer
End Structure
Here's the function - the return value is MyNewRecordSet:
Dim MyNewRecordSet As MyRecordSet <WebMethod()> _
Public Function GetDataReturnList(ByVal sql As String, ByVal sTableName As String) As MyRecordSet
MyNewRecordSet.lstOfDataInRecord = New List(Of String)
[Code] .....
Anyway, I see it's a conversion issue, but not sure how to resolve it. This is my first attempt to use a public structure in a web service and receive a return on it from my app.
Put A Wrapper Around Some Functionality That Uses A Web Service To Return Some Information?
Nov 28, 2011This is annoying. I'm trying to put a wrapper around some functionality that uses a web service to return some information. The intention is to wrap all of that communication into a dll such that the user can simply call functions from the dll to get back information, without needing to care about the service.As far as I can tell, that isn't possible, because the service information, as far as bindings and endpoints, HAS to exist in the app.config of the program that references the dll. That means that anybody using this dll won't just be able to add a reference to it and use it, like they would with any other kind of dll, they must also edit their app.config to add in a bunch of information. That's a simple copy and paste job, but it's incredibly unfriendly, and exposes some of the internal workings of the dll to casual inspection.
View 8 RepliesVS 2005 - Return Value From Asynchronous Web Service Call
Aug 13, 2009I'm using ASMX web services in VB.Net in VS 2005. I am calling a function method on the web service that returns a true or false value. This works fine if I call the the web method synchronously, but if I want to call the method asynchronously, the function returns to a sub and there is no return value; therefore, I can't tell whether the result of call is true or false. Is there a way to make an asynchronous call and still get the true or false result (perhaps using the userState Object)?
For Example:
Dim MyResult as Boolean = MyService.GetResult(10)
Dim MyResult as Boolean = MyServer.GetResultAsync(10)
This doesn't work the compiler complains: "Expression Does Not Produce a Value"

Class To Return An Object?
Nov 14, 2010I have a class i've called "buttons", which passes in 1 variable, the button text, and then returns a new button with that text. however, i do not know how to get the class, when called to return a button.
similar to how 'toString' works, except it would return a button object instead of a string. (im not sure how toString works in vb.net. in java it is automatically called when you call the new class, so newclass and newclass.toString(); return the same) [code]...
Referencing A Class As A Web Service
Nov 18, 2011I am building application that will be hosted as a web service. This app takes an employeeID and returns an employee object that contains lots of info regarding the employee. (name, status, full-time/part-time, etc)I want the two existing apps we have (and more to come) to be able to call a method that the web service will have and return the employee object. (also at time this web service that returns the object may have new fields added to it - Pay rate, etc)How would I go about creating a new object from this web service reference in the existing applications.Would I decalre it like Dim Employee as new emp_webservice.employee? And then be able to use this object within the app? Or would the better practice be to also included the same class files? It seems like this would not be the way to go, since if I make a change to that class I then have to make it in all places.

View 3 RepliesHow To Consume A Web Service In A .NET Class Project

I can create the .NET class web project and add a web service (Visual Studio 2005) but I cannot seem to figure out how to reference it. It's easy to reference in a web site (simply address it by name), but apparently in the class library project things are different because I cannot figure out the namespace or reference name.
View 2 RepliesShared Class Across A Web Service Boundary?
Aug 15, 2011I have a class in a shared library, that I have added references to on both the webservice and the client project. One of the functions in the webservice returns a list of this class.
when I try to cast the return value into a List of the class on the client side, I keep getting an error telling me that a 1-dimensional array of type '<webservice.class>' cannot be converted to type '<sharedlib.clas>'.
The reason that I put the class into the shared library, was because I wanted the webservice to return strongly typed data, but I also have a couple of methods in the class. I dont care about them on the server side, but they are needed on the client side. I figured that this would be the "better" method, since in a shared library it is only declared once for both projects.
Custom Class Constructor Needs To Be Able To Return Error
Mar 12, 2010I'm making a class that reads a file and processes data in it, but I need some error handling. I'm giving it a constructor that takes a file location and processes that file. How can I make it so the constructor tells the program whether it found the file or not? Optimistically the program that calls this class would check for that first, but since I'm not going to be the only one that uses this class I'd like to know how to secure such a thing. It's probably bad practice to do this within the class, but I'd like to be sure it's as portable as possible.
