Well i encountered a simular problem when i didn`t knew exactly what the
server `s ip / name or port is

as my program is beeing shipped to customers i do not know how and on wich
computer the server is configured

so instead of the need to change the config file and restart the app every
time , i came up with this solution

VB.NET Code ::::::::
Private Sub frmMain_Load(ByVal sender As Object, ByVal e As
System.EventArgs) Handles MyBase.Load

System.Runtime.Remoting.Channels.ChannelServices.RegisterChannel(New
System.Runtime.Remoting.Channels.Tcp.TcpChannel)

End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click

Try

cRemote = CType(Activator.GetObject(Type.GetType("RemotingSample.NHSBL,
RemoteBL"), "tcp://" & TextBox1.Text & ":" & NumericUpDown.Value.ToString()
& "/NHSBL"), RemotingSample.NHSBL)

cRemote.NewClient()

Catch ex As Exception

Label2.Text = "Could not connect to the service ! " & vbCrLf & "are you sure
the service is running ? "

Label2.Visible = True

Beep()

Exit Sub

End Try

blnConnected = True

End Sub

in textbox1 the user can enter the ip or servername and try to connect to
the service

i am currently bussy to find a way that i can do a broadcast on the network
to discover the availlable running servers so the user can make a selection
in a drop down list ( see my previous post ) however it seems i am
inventing the weel ( again ??? )
