我可以在 Windows 服务中有一个函数并将数据返回到 vb.net 应用程序吗?
这是我在 Windows 服务中的示例代码:
Protected Overrides Sub OnStart(ByVal args() As String)
' Add code here to start your service. This method should set things
' in motion so your service can do its work.
EventLog1.WriteEntry("In OnStart")
End Sub
Protected Overrides Sub OnStop()
' Add code here to perform any tear-down necessary to stop your service.
EventLog1.WriteEntry("In OnStop.")
End Sub
Protected Overrides Sub OnContinue()
EventLog1.WriteEntry("In OnContinue.")
End Sub
Protected Overrides Sub OnCustomCommand(ByVal command As Integer)
Dim mymsg As String
Dim servicestorun As New System.ServiceProcess.ServiceBase
If (command < 128) Then
MyBase.OnCustomCommand(command)
Else
Select Case command
Case 129
mymsg = "i want this msg to my vb.net application"
Case Else
End Select
End If
End Sub
这是我的 vb.net 应用程序代码:
Dim myServiceController As New System.ServiceProcess.ServiceController("MyNewService")
Dim status As String
Try
myServiceController.ExecuteCommand(129)
' i want to get the msg from my windows service "i want this msg to my vb.net application"
status = "Custom Command Executed Successfully!"
Catch ex As Exception
status = "Failed To Execute Custom Command! " & ex.Message
End Try
请需要帮助。
