Re: help with VB.NET?

[Andrew Kilgore <andrew.kilgore@xxxxxxxxx>]

Hi Ian,

I'm on my 2nd week of .NET so I can understand your frustration...!?!
I doing it in C# so even if I could give an example off the top of my
head (which I doubt would be correct anyway!) I'm not sure how much
use it would be in VB (as VB hides some stuff delegate from you I
think).

First advice: MSDN Magazine column/issue archive
http://tinyurl.com/a8m9y

Have a hunt there and then in all the usual haunts (CodeProject, CodeGuru
etc.)

Hope this helps,
Andy.
