Hi,
I'm looking for some help on a small program that I'm trying to develop in
VB.NET. I'm having trouble getting the code that I've written to work, can
anyone shed some light as to where I'm going wrong.
The program has been written to do the following tasks:
- Select remote server
- Select from two specific services
- Check the status of the server
- Ability to stop/start selected service.
I've listed the code below from mainFrm.vb:
Any help would be much appreciated.
Thanks
Scott
