Status of Windows Services

[Scott Davies]

Hi,

I'm looking for some help on a small program that I'm trying to develop in
VB.NET.

The program I'm trying to develop needs to be able to do the following:

- Select remote server
- Select from two specific services
- Check the status of the server
- Ability to stop/start selected service.

The problem that I've got is that the status only returns a numerical code
instead of "Running" or "Stopped" etc, and the status doesn't always appear
in my textbox. I also get a return value stating the service is stopped when
it is in fact started!!

Any help would be much appreciated as this is driving me mad :-)

Thanks

Scott
