Small code fix

Have a small fix to stop people opening up 2 instances of the updater up at the same time, thus stopping people (in theory) getting the "access is denied" error because the file is already locked:

In Public Sub New() under the comment "'Add any initialization after the InitializeComponent() call":

Code:

Dim gotit As Boolean
Dim mut As New Mutex(True, "EQ2UpdateMut", gotit)

This creates a Mutex that is locked til the program ends. If you start another instance of it up then it tried to get access to this mutex, can't, and exits nicely with "1 instance" error message.

thanks this is much simpler than the way i was doing it...and it always works

sorry for not having so much knowledge of vb.net to know this but that should change this year when i start college getting my computer science degree. thanks again for the info; I would love to hear any other suggestions from you if you have them.

No probs. You've done a great job with the updater for someone who doesn't know VB.NET (you've done a great job with it for someone who does too). I currently develop C# for a large company and I wouldn't want to undertake something like the updater as a first project. Usually people just go for a "hello world" program
