Visual C# General
Hi everybody,
I have a problem with win services. I want to access a win service above a web service, I mean I have a win service that always run on computer and I must access some of the methods on this service. How can I do it Please help me about this. Thank you for all answers...
I do not have any error, because I also do not have any code
. I am using C# and I write a win service and this win service has a method for adding two numbers. OnStart event this method runs. But I want to call this adding method on a web service ( I want to use win services's method remotely ). I counld not find any code to implement this. Thats it...
Ok I think I find the solution, I can reference a win service to web service. I had supposed that I counld not do it. But I would do. Thank you very much for your interest...
To communicate with a running Windows Service you must provide some means of inter-process communications within the Windows Service. Accessing the Windows service's assembly via a web service is executing code in the Web Service, not accessing a running Windows Service.
Hi,
If you want to call a method in windows service from a web service, you have to add reference to System.ServiceProcess.dll and use ServiceController Class in the web service, and then override OnCustomCommand method in the windows service.
For Example.
Imports System.Web
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.ServiceProcess
End Try
Return status
End Function
End Class
Protected Overrides Sub OnCustomCommand(ByVal command As Integer)
If (command < 128) Then
MyBase.OnCustomCommand(command)
Else
Select Case command
Case 129
'Do Something.
Case Else
End Select
End If
End Sub
The following threads include good samples.
