I just started programming in Visual Basic.NET about a month ago, so I am
completely oblivious as to which libraries to look in. However, I have good
experience with Java and C. Below are ten extremely simple questions which I
couldn't seem to find the answers to after looking in some text and
searching through the libraries:

I looked many places for the library that parses Strings into different
number formats, but couldn't find one.
Ex:
Dim str As String = "8.93"
Dim num As Double
num = ???
If I want num to be set to 8.93, which method of the String cl*** should I
use?


When I implement the Try... Catch... Finally set, I can't quite get the
clause to function the way I want it to. Take the following piece of code:
____ 'Start
Dim slots(3) As Integer
Try
slots(4) = 3
Catch Except As IndexOutOfBounds 'or something
'catch code here
Catch Except As Exception
'other catch code here
___ 'End
if I want to have a certain exception handled one way and any other
exception all handled in one general way, what do I need to do. If I type in
the above code, I always get the the general code executed, even if the
IndexOutOfBounds exception was thrown.

Almost everybody in this newsgroup is using VB6 or lower. While you may
get a stray answer to VB.NET questions here, you should ask them in
newsgroups devoted exclusively to .NET programming. Look for newsgroups
with either the word "dotnet" or "vsnet" in their name.

For the microsoft news server, try these newsgroups...

microsoft.public.dotnet.general
microsoft.public.dotnet.languages.vb
microsoft.public.vsnet.general

There are some others, but these should get you started.

look at the System.Convert.ToInt32( stringToConvert )
method in the System namespace

I'm more familiar java too and still exploring dot-net
- look at .net's 'namespaces' as similar to java 'packages' - at least
that's my impression so far

do this...

Dim slots(3) As Integer
Try
slots(4) = 3
Catch Except As IndexOutOfRangeException
'catch code here
MsgBox("IndexOutOfRangeException")
Catch Except As Exception
'other catch code here
MsgBox("General Exception")
End Try
