Hi, I have a string with a name in it: 'bob smith'. I want to parse the string and retrieve the first character of the second name, but not sure where to begin.

Any help would be appreciated,

You  can look for BOB and then thake the second name

        Dim strText As String = "asdfasdf asd bob smith asdfasdfas"
        Dim strSecondNameFirstLetter As String
        strSecondNameFirstLetter = strText.Substring(strText.IndexOf("bob") + 4, 1)

You can use IndexOf() to find the space, then Substring() to grab the next character:
Dim str As String = "bob smith"
        Dim space As Integer = str.IndexOf(" ")
        If space <> -1 AndAlso (space + 1) < str.Length Then
            Dim FirstLetterOfSecondName As String = str.Substring(space + 1, 1)
        End If

Another approach would be to Split() the string:
Dim str As String = "bob smith"
        Dim values() As String = str.Split()
        If values.GetUpperBound(0) >= 1 Then
            Dim FirstLetterOfSecondName As String = values(1).Substring(0, 1)
        End If

Try this:

Dim name As String = "bob smith"
Console.WriteLine(Regex.Match(name, "(?<=\s)\S").Value)

heres a good sample for you to play with:

  'strName =  " Title First MI Last + Credentials"
    Public Sub CheckForTitle(ByVal strName As String)
        Dim regExp As New Regex("([a-zA-Z]{1,})\.{1}\s{0,}([a-zA-Z]{1,})\s{0,}([a-zA-Z]{1,})\s{0,}([a-zA-Z]{1,})\s{0,}([a-zA-Z]\.)([a-zA-Z]\.)")
        Dim matchGroups As GroupCollection = regExp.Match(strName).Groups

        ' Title name
        ' First name
        ' Middle initial (If any)
        ' Last name
        '  Credentials
        MsgBox(matchGroups(5).Value + matchGroups(6).Value)
    End Sub
