Calling dynamic web methods via a windows service

Hi Experts!

We're using a windows service, which runs all the time and has 5 timers defined, that calls specific web methods, via a web service, every second, when it's not locked and available. My question now is:

How can we make the calling of web methods dynamic? In other words, we want to use a config file, define the timers' intervals in there, and specify methods to be called for every timer. Then in our windows service code we will have something like this:

Private Sub timer1_Elapsed(.....)
  .
  .
  .
    theWebserviceObject.DynamicMethod1_SpecifiedForTimer1_InConfigFile()
  .
  .
  .

End Sub

Private Sub timer2_Elapsed(.....)
  .
  .
  .
    theWebserviceObject.DynamicMethod1_SpecifiedForTimer2_InConfigFile()
  .
  .
  .
End Sub

ect
.
.
.

Any suggestions?

Use Reflection

Something like
theWebserviceObject.GetType.InvokeMember("DynamicMethod1_SpecifiedForTimer1_InConfigFile", Reflection.BindingFlags.Default Or Reflection.BindingFlags.InvokeMethod, Nothing, theWebserviceObject, Param)

It worked like a charm thank you!

One more question though, won't hold it against you if i don't get an answer to this one, but i'll add another 75 points to this question;

Do you by any chance know which OTHER windows services should be started first, before i can use my windows service to call a web service?

I know I'm using SQL server to write queries (logs) into the db, so "SQL Server (MSSQLSERVER)" (by default) is definately 1 of them. Any others? Web services or www, or IS or something?

Use ServiceController class to get a snapshort of all the services currently running on your machine at any instance
http://msdn2.microsoft.com/en-us/library/system.serviceprocess.servicecontroller(VS.80).aspx

something like
Dim services() As ServiceController
services = ServiceController.GetServices("MyMachineName")

This is the code that i managed through google @ this stage, but i dunno which services 2 start...
            'Check whether the SQL server service is running:
            Dim SQLServiceController As New System.ServiceProcess.ServiceController("SQL Server (MSSQLSERVER)", CStr(getConfig("EAPoller.ServerName")))
            If SQLServiceController.Status = ServiceControllerStatus.Stopped Then
                SQLServiceController.Start()
            End If
            SQLServiceController.WaitForStatus(ServiceControllerStatus.Running)
            SQLServiceController = Nothing

I dont know..

May be you should look for WWW service or IIS admin service on XP
or look for the process aspnet_wp.exe running

or may be you look for w3wp.exe running on Windows 2003 server
