Best Strategy To Simulate A .net Web Service Without A Server?
Apr 18, 2011
I have inherited a .NET 4 VS2010 solution consisting of a WinForms app and a web service. I don't have access to a server that's running a copy of the web service but I have to run, debug, upgrade and test the project that accesses the web service as well as the web service code.Later, I also want to quickly switch between a deployed web service and the code in my local projectWhat's the best strategy for changing the projects so I can make changes to both projects, test locally, deploy the web service then test against that? If I find issues, I want to switch back to "local" mode to debug.

Im a new in this VS2008. But i have some foundation of programming in VB6.0. So im planning to create this application using VB since im familiar in that language.I downloaded a Visual Studio 2008 and SP1 - now on its 90-day trial, and planning to buy the full version depending if it will meet my needs. I just read afterwards the conditions and how to buy it. I hope its free shipping and credit card is acceptable.^^
I need to make an application something like a reporting system, my plan application is a client-server application. Currently im reading the How to topics and some walkthroughs so far so good. Now here are some sort of details and target need to fulfill.
1. An interface from client that will input the data from the multiple-user , including images and these data will be saved in database/table remote server (center database server) LAN.

Would it be a good idea to start converting forms into .NET one at a time which you would then invoke from the VB6 app via COM-interop.This way, by the end of the process you would just convert the 'shell' of the VB6 application into a new .NET app, and all your forms are ready to go in .NET.

is it possible to implement strategy pattern with different parameters in VB.net? For example I have the following code:
Public Interface InterfaceDataManipulation
Sub updateMyData()
End Interface
How to implemente updateMyData in the class that implements above interface class with different parameter,for example in class x :
Public Class X
Implements InterfaceDataManipulation
Public Sub updateMyData(ByVal x as String)[code]......
But the IDE raises an error "class x must implement updateMyData on interface InterfaceDataManipulation"

I developed app which accepts user responses. I created secondary labels which I envisioned as larger "tool tips" which prompt the user. ("prompts")As the user inputs to either combo box or text box, the label should go invisible and a "prompt" for the next input should go visible.I am trying to use Selected Index Changed,Leave, or LostFocus events to accomplish the visible invisible change.Is that the most effficient way to accomplish my functionality? A twist I would like to incorporate: the purpose of the "prompts" is to guide an unsophisticated user through the app the first couple times.After familiarity is acheived the "prompts" can be annoying.My strategy is to allow user to turn off the "prompts" by a check box.Then my conditionals will test the checkbox. checked property and either show the "prompts" or not based on the test.

We have a asp.Net vb.net 2008 project on tfs2010. The project has one main branch and for any release we create a new feature branch which is finally deployed. Post production deployment we merge back the branch back into main branch.We are now also adding a db project to manage our SQL too. Question is how to version control the differential scripts. The db project contains all create scripts which is fine if we had to deploy thep project from scratch but the project is already live. So now any new release or hotfix would normally contain alter or change script practically.

I'm about to start a new project and want some advice on how to implement.I need a web application which contains a booking module for reserving timeslots, and a time management module which will enable employees to clock in / clock out.
If I am writing an update to the time managment module, I don't want to disrupt the booking engine availability by releasing a new solution containing both modules.to make things more difficult, there is some shared functionality like common users, roles and security.Here's a suggestion I've gotten, which sounds a bit cruddy, but may be functional.Write a 'container' web application which consists of basically a frame, and authentication / security features. This then has links which, will load the 2 independantly built and released web applications into the frame.I can see that say, if I wanted to update the time management module,

I'm trying to bind a WinForms TreeView control to some user-defined objects. In particular, I'd like to bind aTreeNode.Text property to myObject.Name. My strategy is to create xTreeNode, a subclass of TreeNode, add a DataBindings collection, and expose its Text property.
This would allow me to write some code like this:
Dim oBinding as Binding
Dim bs as New BindingSource
bs.DataSource = myObj

I have a solution in VS 2010: a WCF Service Library project ("NotifyService") and two Windows Forms projects, one for a server ("NotifyServer")and one for a client ("NotifyClient"). My goal is to have a duplex WCF service that will notify any number of connected clients when the server pushes out a notification. The clients do not need to communicate to the server except to subscribe and unsubscribe from the server's updates. However I seem to be running into problems nailing down the InstanceContext.
Here's the code for the WCF service:
<ServiceContract(
CallbackContract:=GetType(INotifyCallback),
SessionMode:=SessionMode.Required)>
[Code].....
Since I'm setting everything up through code, there are no app.config files. The problem I'm having is that my Subscribe method is never called. When debugging, I get an error after stepping through that line (not an exception) that says "Unable to automatically step into the server. The debugger failed to stop in the server process." When I go back to my server form and click the button designed to raise an event on the callback clients, it steps into the NotifyService class but the _callbacks list is empty, meaning the Subscribe method either never ran, or it never ran on that instance.
I have fought with this for almost a week. This is nearly an identical copy, at least on the service-side, to what was described here, and I've compiled that and it works.

I am hoping to get some advice on a project that I am wanting to work on. I have never done a web service/windows service or anything along the lines of what I am thinking so I would like some advice from some more experienced developers.I will be using VS2008 and VB.NET. My company currently mostly works in .NET 2.0 for our commercial application, but since this will be used mostly in house I would be able to use .NET 3.5 if suggested (am just not overly familiar with the additional features in .NET 3.5).What I would like is to have a server/service that communicates with multiple PCs. I want to create an application/web page (not familiar with web development so would probably start out as a winform app and possibly move to a web app to consume the service) that would query the web service/remoting service/whatever to retrieve information from each of the PCs (track the version of the application that is running, retrieve log files, push an update program to the PC (to be run manually)).
Not being too familiar with this type of scenario I was thinking something to the effect of:Each PC run a Windows Service that monitored the local PC. When something changes (software update installed?), tell the web service that the new version is installed.A service (web service? remoting server? other?) running on a PC that would be the interface to the windows service (not sure how the web service would talk to the Windows service without the Windows service initiating, though, unless it is also running a server) on the individual PCs. The service could request an update from the PCs (get the software version, request a file). The service would also be able to push an update program to the PCs to be run manually.

I have developed several Windows Services applications which all use SQL server. In some occasions, the customer shuts down the server and then restarts it the following morning. But then, my service is started BEFORE SQL Server starts and, of course, fails.
In which order are the services started ?

I have a usercontrol with a picturebox and a few buttons related to it, such as LoadFromFile, Paste and Zoom (that last one pops up a new form). Is there a way to override the basic Enabled property of the usercontrol so that I can keep the Zoom button active all the time, while turning off the other buttons?
I realize there are 2 "obvious" replies. don't do Enabled=False, create a custom method. do everything in the one form, not a usercontrol, so you can pick and choose disabling. Both are less than ideal, given that I'm putting this control into a couple of existing forms, so I'd like to work around how those forms already behave. So is there a way to override the behavior of my usercontrol when it gets disabled? What would be my best strategy?

I've got a webservice called Converter.asmx and I've just noticed that on the remote server I basically can't connect to it. The error that I get: "No connection could be made because the target machine actively refused it 127.0.0.1:49792" and the error occurs where I'm calling the web service (second line below).
Dim webservice As New localhost.Converter
results.InnerHtml = webservice.ParseData(txtInput.InnerText, options)
On my localhost it works fine. How can I change the webservice so that it'll work on the remote host as well?

I have a windows service written in .net framework 2.0. This service installs and runs perfectly fine on both XP and windows server 2003.We have a new 2008 box that we are migrating over to, so need to get this windows service up and running.When i try to 'start' the windows service on the 2008 machine, i get "Windows could not start the <service> service on local computer. Error 1053: The service did not respond to the start or control request in a timely fashion."I have searched everywhere looking for an answer, and all I could find was a fix attributed to .net framework 1.1 for this same error. That; however, is not applicable here, as the service was written in 2.0.

I created a windows application service that runs every 20 seconds to collect data from avaya cms and then dump it into a database. I did this using a timer. Since I had to have access to the clipboard to get the data and parse it, I had to be in STA. Unfortunately,just putting the STA before the Main() (or any other sub) did not keep the service in single thread mode. So I had to create a new thread and join it like so:
Public Class CMS
Protected Overrides Sub OnStart(ByVal args() As String)
Timer1.Enabled = True
Timer1.Start()

In our solution we have a web service that normally runs on a server, however we can build the webservice on our localhost for debugging as well. However, now whenever I grab the project from source safe it is building the webservice as a website instead of a developer web server.

i am looking into web services to be used for a windows forms application that i want to connect to my website and return data from my database. One thing i am concerned about is security. I have only played with web service a little bit but it seems to allow direct access to it by url and then run the service, showing the results in the browser. i guess i could set it up to accept a password in the code. i guess really if i have to pass in the query criteria to the sql from the application then showing the records in a browser should not be a problem. in my web application for the site i can keep all my web services in the app_data folder for no browser access.
i just need some advice in this area. goods, bads, other options if better. i don't have a full grasp on working this way from a client side windows application.

I have a windows service application that is meant to interact with SQL server database (INSERT, UPDATE, ETC). The windows service application is also multi-threaded.I created an "App_Data " folder to keep my database and used app.config file for connection information, etc.
After installing and starting the service, nothing happens, the database doesnt get updated, etc.
Has anyone ever written a windows service application that interacts with a database? Kindly advice me on how to overcome this problem..

i have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:
Warning: Type library exporter encountered a type that derives from a
generic class and is not marked as
[ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be
exposed for such types. Consider marking the type with
[ClassInterface(ClassInterfaceType.None)] and exposing an explicit
interface as the default interface to COM using the
ComDefaultInterface attribute.
It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.
